Description

  The present invention relates to a cable holder for holding a cable extending from a microphone device.

  2. Description of the Related Art A microphone device that converts an input voice into an electric signal is known (see Patent Literature 1). The microphone device includes a normal microphone device having no recording function and a microphone device having a recording function having a recording function. An ordinary microphone device has only an audio signal output function of outputting an audio signal converted into an electric signal to an external audio device such as a recording device or a speaker. On the other hand, a microphone device with a recording function has, for example, an IC memory in which an audio signal is recorded and a control circuit for recording the audio signal in the IC memory, in addition to the microphone. In a microphone device with a recording function, in addition to a microphone and IC memory, an output terminal for outputting an audio signal to a built-in speaker, an external speaker, headphones, or the like is housed in a portable housing to reproduce the audio signal. Some portable recording devices are also available. Such a portable recording device is called an IC recorder or the like.

  As in the microphone device described in Patent Literature 1, some microphone devices can be used by being attached to a digital camera capable of shooting moving images. When the microphone device is mounted on a digital camera, for example, a base for the microphone device is attached to an accessory shoe of the digital camera.

  When the microphone device is a normal type having no recording function, a cable for outputting an audio signal to an external device is connected to the microphone device, and when the microphone device is a portable recording device having a recording function, a headphone cable is used. Cable is connected. A holder for holding the above-described cable is indispensable for such a pedestal for a microphone device. This is because careless movement of the cable not only makes it difficult to use the digital camera, but also causes unnecessary noise due to the cable coming into contact with the digital camera body. Therefore, in Patent Literature 1, a holder is provided on a pedestal.

  However, the diameter of the cable may vary depending on the type of microphone device and the type of headphones. In this case, if only one type of diameter is supported, as in the case of the holder described in Patent Literature 1, there is a problem that the holder cannot be used for a cable having a diameter different from the diameter of the holder. As a solution to such a problem, it is conceivable to provide a plurality of types of holder portions. However, since the pedestal on which the microphone device is mounted is small, a space for providing a plurality of holder portions for a plurality of types of cables having different diameters is provided. Is difficult to secure. Although it is conceivable to use a binding band, there is a problem that the design is impaired. In addition, since many users use the existing pedestal, there has been a demand for effective use of the existing pedestal for the convenience of the user.

  1 to 3, a cable holder 10 of the present invention is detachably attached to a pedestal 13 for mounting a portable recording device 11, which is a microphone device having a recording function, on a digital camera 12. A cable such as a headphone cable can be connected to the portable recording device 11, and the cable holder 10 is for holding the cable. The cables include, for example, a first cable 37 shown in FIGS. 4 and 5 and a second cable 38 shown in FIGS. 1 to 3, 5 and 6. The first cable 37 and the second cable 38 have the same function as a headphone cable, but have different diameters as shown in FIG.

  The portable recording device 11 is provided with a microphone 16 for converting an input audio signal into an electric signal. As the microphone 16, for example, a condenser microphone is used. The portable recording device 11 includes a data storage device (not shown) such as an IC (Integrated Circuit) memory for recording an audio signal converted into an electric signal by the microphone 16 in a main body 17.

  On an upper surface of the main body 17, a plurality of operation buttons 18 used for performing operations such as reproduction and recording, and an indicator 19 for displaying various states such as a status during reproduction or recording and a recording time are provided. I have. On the lower surface of the main body 17, an attachment portion (not shown) for attaching to the pedestal 13 described later is provided.

  On the side surface of the main body 17, a slot 21 in which a memory card for recording an audio signal can be inserted, and a USB (Universal Serial Bus) connector 22 for transmitting the recorded audio signal to the outside are provided. (See FIG. 3).

  Further, on the side surface of the main body 17, a jack 23 which is an external output terminal for outputting an audio signal recorded in the IC memory to the outside is provided. A plug attached to one end of the first cable 37 or the second cable 38 is connected to the jack 23. An external speaker can be connected to the jack 23. A power switch, a volume control button (both not shown), and the like are provided on the opposite side surface of the main body 17.

  The digital camera 12 includes a camera body 25 and a lens device 26 that can be detachably attached to the front of the camera body 25. The camera body 25 is provided with a photographing device, an image processing device, an image recording device, an audio recording device, and the like. The lens device 26 has a lens barrel 27 and a photographing optical system 28 including a zoom lens and a focus lens. A motor for zooming, a motor for focus adjustment, a motor for camera shake correction, and the like are stored in the lens device 26.

  A release button 29, a mode setting dial 30, an accessory shoe 31, and the like are provided on the upper surface of the camera body 25 (see FIG. 2). The release button 29 is used for giving a shooting instruction. The mode setting dial 30 is used to select a still image shooting mode, a moving image shooting mode, a playback mode, and the like. The accessory shoe 31 is for attaching an external flash device (not shown) or the pedestal 13.

  The pedestal 13 has a cylindrical pedestal main body 32, legs 33 for attaching the pedestal main body 32 to the accessory shoe 31, and a holding ring 34. The pedestal body 32 has an opening 50 into which an engaging portion 43 of the cable holder 10 described later is inserted (see FIG. 4).

  The accessory shoe 31 has a rectangular planar shape, and has a pair of bent pieces 31a that are bent inward at both ends so as to face each other. A gap into which a flat plate can be inserted is formed at each end of the accessory shoe 31 by each bent piece 31a.

  The leg 33 has a flat plate shape, and when the pedestal 13 is attached to the accessory shoe 31, both ends of the leg 33 are inserted into gaps formed by the bent pieces 31a. When the holding ring 34 is rotated while the legs 33 are inserted into the gaps, the holding ring 34 moves from above in the direction of pressing the bent pieces 31 a, and is bent between the legs 33. The piece 31a is pinched. As a result, the pedestal 13 is fixed to the digital camera 12.

  The pedestal 13 has a mounting part 35 and a first holder part 36. The mounting unit 35 can be mounted on a mounting device (not shown) provided on the lower surface of the portable recording device 11. The mounting unit 35 has a structure for preventing vibrations generated by driving various motors and operating the digital camera 12 from being transmitted to the portable recording device 11.

  The mounting portion 35 is attached to the pedestal 13 in a floating manner, for example. For example, a damper made of an elastic material such as a spring or rubber is provided in the pedestal 13, and the mounting portion 35 is supported by the damper. The damper supports the mounting portion 35 at two points, for example. Therefore, when the portable recording device 11 is mounted on the mounting portion 35, the portable recording device 11 can swing with respect to the pedestal 13 within a predetermined swingable range. Thereby, the vibration from the camera body 25 is absorbed by the damper, and the vibration of the camera body 25 is not easily transmitted to the portable recording device 11. When the vibration from the camera body 25 is transmitted to the portable recording device 11 through the pedestal 13, noise such as mechanical contact sound and collision sound is generated due to mounting play between the pedestal 13 and the portable recording device 11. A sound is generated. Since the transmission of vibration to the portable recording device 11 is suppressed by adopting the floating method, generation of such noise noise can be prevented.

  On the outer peripheral surface of the pedestal main body 32, two first holder portions 36 are provided at a pitch of 180 ° (see FIG. 3). FIGS. 2 and 3 show a mode in which the cable holder 10 is attached to the first holder portion 36. However, the first holder portion 36 originally has a predetermined outer shape as shown in FIG. This is for holding the first cable 37 having the diameter A. The first cable 37 is a cable such as a headphone cable connected to the portable recording device 11 as described above.

  As shown in FIG. 5, the first holder portion 36 has two concave portions 36 a having a C-shaped vertical cross section along the axial direction of the pedestal main body 32. The recesses 36 a are provided vertically above and below in the axial direction of the pedestal main body 32, and the longitudinal direction extends parallel to a tangent to the outer periphery of the pedestal 13. The inner diameter of each recess 36a is formed to be substantially equal to the outer diameter A of the first cable 37. The opening 36 b of each recess 36 a is formed such that the axial length B of the pedestal main body 32 is smaller than the outer diameter A of the first cable 37. The outer sheath of the first cable 37 is formed of an elastic material such as silicon rubber, and can be bent flexibly. Therefore, when the first cable 37 is pushed into the opening 36b, the first cable 37 elastically deforms, passes through the opening 36b, and is housed in the recess 36a. Thus, the first holder portion 36 can hold the first cable 37 by fitting the first cable 37 into the concave portion 36a.

  However, the outer diameter of the cable may vary depending on the type of headphones connected to the portable recording device 11. For example, when a headphone having a second cable 38 having an outer diameter C larger than the outer diameter A of the first cable 37 is connected to the portable recording device 11, the second cable 38 is held by the first holder portion 36. Can not do. To solve this problem, it is conceivable to provide a plurality of first holder portions 36 for a plurality of types of cables having different diameters. However, since the pedestal 13 is small, a space for providing the plurality of first holder portions 36 is required. Difficult to secure. If the second cable 38 moves inadvertently, unnecessary noise may be generated and the sound quality may be degraded.

  Therefore, as shown in FIG. 6, a retrofitted cable holder 10 is used. The cable holder 10 holds the second cable 38 and is detachably attachable to the first holder portion 36. Although a detailed description of the method of attaching the cable holder 10 will be given later, the cable holder 10 is fitted by inserting the fitting portion 41 (see FIG. 7) along the direction in which the concave portion 36a extends. 10 can be attached to the first holder part 36. The second cable 38 is a cable such as a headphone cable connected to the portable recording device 11 as described above.

  As shown in FIGS. 7 to 10, the cable holder 10 has a substrate 40, a fitting part 41, a second holder part 42, an engaging part 43, and a rotation restricting part 44. The cable holder 10 is made of, for example, plastic, and each part is integrally formed. The board 40 has a flat plate shape, and the fitting section 41, the second holder section 42, and the engaging section 43 are respectively coupled to the board 40.

  The fitting section 41 is detachably fitted to the first holder section 36. The fitting portion 41 includes a first fitting pin 41a and a second fitting pin 41b that fit into the two recesses 36a of the first holder portion 36. The first fitting pin 41a and the second fitting pin 41b have one end in the longitudinal direction coupled to the substrate 40, and are arranged at intervals corresponding to the interval between the two concave portions 36a of the first holder portion 36. I have.

  The first fitting pin 41a has a circular cross section perpendicular to the longitudinal direction (see FIG. 9). The second fitting pin 41b has a semi-circular cross section perpendicular to the longitudinal direction (see FIG. 9). The first fitting pin 41a and the second fitting pin 41b correspond to "fitting pins" in the claims.

  The first fitting pin 41a has a tapered shape in which the diameter at one end (base end) connected to the substrate 40 is large and the diameter decreases toward the distal end (see FIG. 10). The outer diameter of the first fitting pin 41a on the proximal end side is formed to be substantially equal to the inner diameter of the concave portion 36a. That is, the outer diameter of the proximal end of the first fitting pin 41a is substantially equal to the outer diameter A of the first cable 37. Like the first fitting pin 41a, the second fitting pin 41b has a tapered shape in which the diameter at the base end is large and the diameter decreases toward the distal end. The outer diameter of the second fitting pin 41b on the proximal end side is formed to be substantially equal to the inner diameter of the concave portion 36a (that is, the outer diameter A of the first cable 37).

  When the cable holder 10 is mounted on the first holder portion 36, as shown in FIG. 6, the cable holder 10 is pushed into the concave portion 36a from the distal end side of the fitting portion 41 along the direction in which the concave portion 36a extends. The first fitting pins 41a and the second fitting pins 41b have thinner distal ends, so that they can be easily inserted into the recesses 36a. When the first fitting pin 41a and the second fitting pin 41b are pushed all the way, the outer peripheral surface on the base end side of the first fitting pin 41a comes into contact with the inner peripheral surface of the concave portion 36a, and the first fitting pin 41a is pressed. The pin 41a is press-fitted, and the cable holder 10 is fixed to the first holder portion 36.

  Further, the second fitting pin 41b has a protruding portion 41c protruding downward from the outer peripheral surface (see FIG. 9). When the second fitting pin 41b is inserted into the concave portion 36a, the protruding portion 41c contacts the inner peripheral surface of the concave portion 36a as shown in FIG. Assuming that the amount of protrusion of the protrusion 41c with respect to the outer peripheral surface of the second fitting pin 41b is D, the second fitting pin 41b is elastically deformed upward in accordance with the amount of protrusion D. Due to this elastic force, the second fitting pin 41b is pressed against the concave portion 36a, and the effect of fixing the cable holder 10 to the first holder portion 36 is improved.

  The second holder part 42 has two plate-shaped parts, a first plate-shaped part 42a and a second plate-shaped part 42b. The first plate-shaped portion 42a and the second plate-shaped portion 42b are joined at the lower ends that constitute one side parallel to the longitudinal direction of each of the fitting pins 41a and 41b, and this portion is a joining portion 48. . On the other hand, in the first plate-like portion 42a and the second plate-like portion 42b, the upper end opposite to the coupling portion 48 is an open end. Thus, the second holder portion 42 functions as a clip having a U-shape as a whole.

  The first plate portion 42a has a flat plate shape, and one end is coupled to the substrate 40. A connecting portion 46 extends from the outer peripheral surface of the first plate-shaped portion 42a toward the first fitting pin 41a. Similarly, the connecting portion 46 extends from the outer peripheral surface of the first plate-shaped portion 42a toward the second fitting pin 41b. These two connecting portions 46 are connected to the first fitting pin 41a and the second fitting pin 41b, respectively.

  As shown in FIG. 11, the first plate-shaped portion 42b has a substantially flat plate shape as a whole, and a facing surface facing the second plate-shaped portion 42b forms a flat plane. On the other hand, the second plate-shaped portion 42b has a gently wavy shape as a whole, and the opposing surface forms a wavy surface.

  A cable holding portion 49 that is recessed in a semicircular arc is provided at a central portion of the wavy surface of the second plate-shaped portion 42b. The cable holding portion 49 is for holding the second cable 38 between the first plate-shaped portion 42a and the second cable 38. Further, the open end of the second plate-like portion 42b is inclined with respect to the first plate-like portion 42a in a direction away from the first plate-like portion 42a, and the first plate-like portion 42a and the second plate-like portion 42a at the open end. The interval between the plate portions 42b is large.

  When the second cable 38 is pushed into the open end of the second holder portion 42, the second plate portion 42b is elastically deformed in a direction away from the first plate portion 42a. Since the open end of the second plate-shaped portion 42b is inclined in a direction away from the first plate-shaped portion 42a, it is easy to insert the second cable 38 toward the cable holding portion 49. When the second cable 38 is further pushed in and reaches the cable holding portion 49, the second cable 38 is held by the semicircular concave shape of the cable holding portion 49 and the elastic force of the second plate portion 42b. This prevents the held second cable 38 from falling off.

  As shown in FIG. 8, the engaging portion 43 extends parallel to the longitudinal direction of the first fitting pin 41a and the second fitting pin 41b, and one end is connected to the substrate 40, and the other end is a free end. It has become. The engagement portion 43 is a member for preventing the fitting portion 41 from falling off from the first holder portion 36 by engaging with the pedestal 13. An engagement claw having a substantially triangular cross section is formed at a free end of the engagement portion 43. When attaching the cable holder 10 to the first holder portion 36, the engaging portion 43 is inserted into the opening 50 provided in the pedestal main body 32, and the tip of the engaging portion 43 is in contact with the inner peripheral surface of the pedestal main body 32. Abut Therefore, in a state where the engaging portion 43 is inserted into the opening 50 of the pedestal main body 32, the fitting portion 41 is prevented from falling off.

  As shown in FIGS. 8 to 11, the rotation restricting portion 44 has a flat plate shape and is coupled to the first plate-shaped portion 42a. The rotation restricting portion 44 prevents the fitting portion 41 from dropping from the first holder portion 36. The rotation restricting portion 44 is provided below the fitting portion 41 so as to protrude to the side opposite to the second plate-shaped portion 42b. When attaching the cable holder 10 to the first holder portion 36, the rotation restricting portion 44 contacts the bottom 51 of the first holder portion 36 as shown in FIG. Therefore, when the rotation restricting portion 44 is in contact with the bottom portion 51 of the first holder portion 36, the rotation of the cable holder 10 around the axis along the longitudinal direction of the fitting portion 41 is restricted, and the fitting portion 41 is prevented from falling off.

  Hereinafter, the operation of the above configuration will be described. When the second cable 38 having an outer shape larger than the inner diameter of the concave portion 36a of the first holder portion 36 is connected to the portable recording device 11, the second cable 38 cannot be fitted into the concave portion 36a. 10 is attached to the first holder part 36.

  When attaching the cable holder 10 to the first holder portion 36, the fitting portion 41 is inserted into the concave portion 36a of the first holder portion 36. At this time, the engaging portion 43 is inserted into the opening 50 of the pedestal 13.

  When the fitting portion 41 is pushed in all the way, the outer peripheral surface on the base end side of the fitting portion 41 comes into contact with the inner peripheral surface of the concave portion 36a. Thereby, the cable holder 10 is fixed to the first holder portion 36. The second holder portion 42 of the cable holder 10 is elastically deformed when the second cable 38 is pushed in from the open end, and holds the second cable 38 by using the elastic force. Therefore, even when the outer diameter of the cable connected to the portable recording device 11 is different from the inner diameter of the first holder portion 36, the pedestal 13 for attaching the portable recording device 11 to the digital camera 12 can be effectively used. And a plurality of types of cables having different diameters can be held. In particular, there are various types of headphone cables connected to the portable recording device 11, and the diameters of the cables are various, which is particularly effective.

  When the fitting portion 41 is pushed in all the way, the substrate 40 near the base end of the engagement portion 43 comes into contact with the outer edge of the opening 50 provided in the pedestal 13. Thus, the pushing of the fitting portion 41 is restricted, so that the cable holder 10 can be prevented from dropping in the insertion direction.

  In addition, the tip of the engagement portion 43 contacts the inner peripheral surface of the pedestal 13. Thereby, the effect of preventing the fitting portion 41 from falling off is improved. Further, the rotation restricting portion 44 contacts the bottom portion 51 of the first holder portion 36. Thereby, rotation of the cable holder 10 around the axis along the longitudinal direction of the fitting portion 41 is restricted, and the effect of preventing the fitting portion 41 from falling off is further improved.

  Since the mounting portion 35 is mounted on the pedestal 13 in a floating manner, the portable recording device 11 is easily tilted within a swingable range. If a cable that cannot be held by the first holder portion 36 is connected to the portable recording device 11, the weight of the cable causes the portable recording device 11 to incline to the limit of the swingable range, and the camera body 25 Is transmitted to the portable recording device 11. Then, the microphone 16 picks up a noise sound generated by the vibration, and the sound quality is degraded. Therefore, when the mounting portion 35 is mounted in a floating manner, the need for the cable holder 10 is particularly high.

  Note that the cable holder 10 is not limited to the above-described embodiment, and a fitting portion 41 that removably fits into the first holder portion 36 and a second cable 38 having a diameter different from that of the first cable 37. And at least a second holder portion for holding the second member. Other configurations can be appropriately changed without departing from the spirit of the present invention.

  In the above embodiment, the portable recording device 11 which is a microphone device having a recording function has been described as an example. However, the present invention can be applied to a microphone device having no recording function. When a microphone device without a recording function is attached to the digital camera 12, for example, an audio signal output from the microphone device is input to the digital camera 12 and recorded by an audio recording device provided in the camera body 25. . Also in this case, the operation and effect when the present invention is applied are the same as those in the above embodiment.
