Hereinafter, a first embodiment of the telephone according to the present invention will be described.
FIG. 1 is a diagram showing an appearance of a telephone 1 according to the embodiment of the present invention. As shown in FIG. 1, the telephone 1 includes a main body 2 and a handset 3. The transmitter / receiver 3 is placed on the cradle of the main body 2 during standby, and is removed from the cradle during transmission / reception. FIG. 1 shows a state in which the handset 3 is placed on the cradle. The main body 2 and the handset 3 are connected wirelessly or by wire (hereinafter, the case of wireless, that is, a cordless phone will be described as an example, but the present invention can also be applied to a telephone connected by wire). The main body 2 is provided with a display unit 4 capable of displaying various information such as the current time, call time, and telephone number, an operation unit 5 that is various operation buttons, and an operation unit 8.

The operation unit 8 includes a numeric keypad for inputting a telephone number and the like, a hold button, an answering machine button, and the like. The operation unit 5 is a button for registering, for example, a telephone number or the like of a partner who frequently calls. The telephone number of the other party can be arbitrarily registered by the user of the telephone 1. In addition to the destination telephone number, for example, shortcuts for frequently used functions (such as various settings) may be registered.

  When frequently used destination telephone application numbers are registered in the operation buttons of the operation unit 5, it is convenient to be able to display which destination telephone number each operation button corresponds to. The holding unit 6 has a function of holding a sheet for displaying a destination name corresponding to the registered destination telephone number.

  In FIG. 2, a sheet 9 on which the registered destination telephone number and the like, the function of the operation button 5 corresponding to the shortcut function, that is, the name of the destination and the shortcut function can be entered is located at the end of the holding unit 6. The place where it inserts from the insertion port 7 is shown. The sheet 9 is made of paper, plastic, or the like, and the user of the telephone 1 can enter the name of the other party. FIG. 2 shows an example in which the name of the other party corresponding to the registered telephone number is entered for five operation buttons (operation unit 5) except for one at the right end.

  FIG. 3 is a diagram showing an example of the structure of the holding unit 6 arranged so as to be adjacent to the operation unit 5 of the main body 2 of the telephone 1. FIG. 3A is a plan view of the holding portion 6, and FIG. 3B is a cross-sectional view taken along A-A ′. The holding part 6 is composed of a bottom part 11 and a guide part 10. Since the guide portion 10 has a shape corresponding to the peripheral portion of the bottom portion 11, the guide portion 10 defines a hole to be exposed so that the sheet 9 can be seen when viewed in a plan view at the center portion thereof. The sheet 9 is inserted between the bottom part 11 and the guide part 10 through the insertion port 7 in FIG. The guide unit 10 has a guide function when the sheet 9 is inserted. A plurality of grooves 30 are formed in the bottom 11 to improve the sliding of the sheet 9. The inserted sheet 9 is held by the holding unit 6 so that the periphery of the sheet 9 can be pressed by the guide unit 10.

  The number of the grooves 30 can be appropriately selected in order to adjust the frictional force acting between the sheet 9 and the bottom portion 11. That is, it is possible to adjust the frictional force acting between the sheet 9 and the bottom part 11 by the number of the grooves 30. In FIG. 3, the number of the grooves 30 is small for easy understanding, but in actuality, for example, about 10 grooves 30 are arranged at a pitch of about 0.5 mm to 1.5 mm.

  The mechanism by which the friction force acting between the sheet 9 and the bottom portion 11 of the holding portion 6 is reduced by forming the groove 30 in the bottom portion 11 will be described as follows. First, by forming the groove 30, it is possible to reduce the contact area between the sheet 9 and the bottom 11 and reduce the frictional force.

Secondly, the contact angle of the water droplet changes depending on the surface shape of the bottom portion 11 and the degree of hydrophilicity changes. When the bottom part 11 is a flat surface, the contact angle between the bottom part 11 and the water droplet is small, the hydrophilicity is increased, and the water droplet easily moves on the bottom part 11. Accordingly, the frictional force acting between the bottom 11 and the sheet 9 is increased. On the other hand, when the groove 30 is formed in the bottom portion 11, the apparent contact angle is increased at the groove portion 30, and the water repellency is increased, and water droplets move on the bottom portion 11 due to the irregularities caused by the groove 30. It becomes difficult. This makes it difficult for water droplets to spread, and the frictional force acting between the bottom 11 and the sheet 9 is reduced.

  As for the direction of the groove 30, the shape along the insertion direction of the sheet 9 has the smallest frictional force. This is because if there is a component in the direction perpendicular to the insertion direction of the groove 30, it becomes an obstacle and the frictional force increases. However, it need not be strictly parallel to the insertion direction. Further, the groove does not need to be a continuous linear shape, and may be a structure that reduces the frictional force when the sheet 9 is inserted.

  Further, the groove 30 does not need to be formed on the entire surface of the bottom portion 11 and may be partial. For example, a character display indicating the location of the insertion opening 7 of the sheet 9 may be added to the bottom 11, and the groove 30 may be disposed in a portion other than the character display so that the sheet 9 can be easily inserted into the holding unit 6. That's fine.

  FIG. 3C is a view showing another form of the guide portion 10 of the holding portion 6. The guide portion 10 is not formed in the portion of the insertion port 7. In this form as well, the sheet 9 can be held as in FIG. In FIG. 3, the guide portion holds the peripheral portion of the sheet 9 in a frame shape. However, the guide portion is not limited to this, and may have a structure in which the entire holding portion is covered with a transparent material.

  In FIG. 3, the groove 30 is formed in the bottom portion 11, but may be formed in the guide portion 10. The formation location of the groove 30 can also be selected as appropriate for adjusting the frictional force.

  FIG. 4 is a block diagram showing a configuration of the telephone 1 according to the embodiment of the present invention. As shown in FIG. 4, the main body 2 includes a main control unit 25, a RAM (Random Access Memory) 21, a non-volatile memory 22, a public line control unit 23, an audio reproduction unit 24, a display unit 4, and an operation. Unit 5 and radio unit 20. The operation unit 8 described above is included in the operation unit 5 in FIG.

  The main control unit 25 controls each unit constituting the main body 2 according to a control program stored in the nonvolatile memory 22. The nonvolatile memory 22 stores a control program and the like. The RAM 21 functions as a main memory of the main control unit 25. Information on the destination telephone number and various setting shortcuts registered in the operation unit 5 used in the present invention is stored here. The public line control unit 23 is connected to a public line. The main control unit 25 can control the public line control unit 23 to make a call with another telephone.

The display unit 4 includes a display device that can display various information such as the current time, call time, and telephone number. When the operation button of the control unit 5 is pressed, the registered destination telephone number and the contents of various setting shortcuts may be displayed.
The voice reproducing unit 24 causes a voice (not shown), a ringing sound, the contents of an answering machine, an alarm sound, etc. to be generated from a speaker (not shown).

As shown in FIG. 4, the handset 3 includes a main control unit 29, a RAM (Random Access Memory) 27, a nonvolatile memory 28, and a wireless unit 26.
The main control unit 29 controls each unit constituting the handset 3 according to a control program stored in the nonvolatile memory 28. The nonvolatile memory 28 stores a control program and the like. The RAM 27 functions as a main memory of the main control unit 29.

The main body 2 and the handset 3 are cordless telephones connected wirelessly. The wireless connection is performed via the wireless unit 20 and the wireless unit 26.
The present invention will be described by taking the above-described cordless telephone as an example. However, the present invention can be similarly applied to a so-called parent-child telephone or portable telephone having a parent machine and a child machine. . Further, the main body 2 and the handset 3 may be connected by wire.

  Next, details of the first embodiment of the telephone 1 of the present invention will be described with reference to FIG. FIG. 5 is an enlarged view of the left end portion of the holding portion 6 of the telephone set shown in FIG. The holding unit 6 is disposed adjacent to an operation button (operation unit 5) in which a telephone number or the like is registered. The holding portion 6 is formed with a groove for reducing a frictional force acting between the inserted sheet 9 and the holding portion 6. A guide portion 10 is arranged around the holding portion 6 in a frame shape. The sheet 9 is inserted into the holding unit 6 from the right side of FIG. In the vicinity of the left end of the holding part 6, a convex part 31 is formed for increasing the frictional force acting between the sheet 9 and the holding part 6.

  6 is a plan view and a cross-sectional view of the holding unit 6 in FIG. 5, and the names and functions of the respective parts are the same as those in FIG. 3. FIG. 3B is a cross-sectional view taken along the line B-B ′ in the vicinity of the side opposite to the insertion port 7 in FIG. A convex portion 31 for increasing the frictional force acting between the sheet 9 and the holding portion 6 is formed. The convex part 31 protrudes from the guide part 10 to the bottom part 11 side, and the space between the convex part and the convex part of the bottom part 11 is narrow. This gap is formed to be equal to or narrower than the thickness of the sheet 9.

Thereby, the sheet 9 inserted from the insertion port 7 can be easily inserted into the holding portion 6 by the structure of the groove 30 formed at the bottom. Then, when the sheet is inserted to the vicinity of the side opposite to the insertion port 7 of the holding portion 6 (near BB ′), the friction force acting between the sheet 9 and the holding portion 6 is increased by the convex portion 31. However, since the sheet 9 is almost inserted into the holding portion 6, it is easy to insert the sheet 9 beyond BB ′ and complete the insertion into the holding portion 6.
The position where the convex portion 31 is formed can be appropriately determined from the material of the holding portion 6 and the sheet 9 and the structure of the holding portion 6, but the sheet 9 has a width in the insertion direction of the holding portion 6. Is more preferably formed at a position where about 70% or more is inserted from the insertion port 7.

  With this structure, even if the telephone 1 that has been inserted into the seat 9 is tilted due to, for example, movement of the installation position, the frictional force is high at the convex portion 31, so that the seat 9 is prevented from slipping out. it can.

In addition, although the convex part 31 is formed in the both sides of the guide part 10, respectively, one side may be sufficient and a convex part may be formed in the bottom part 11. FIG. Further, the shape of the convex portion does not need to narrow the gap between the convex portion 30 and the bottom portion 11 at one point, and the gap between the bottom portion 11 and the guide portion 10 may be narrowed in a linear or planar shape. That is, a structure that narrows the gap and increases the frictional force in the vicinity of the insertion opening 7 is preferable.

As described above, the groove 30 is formed in the holding portion, and a portion having a higher frictional force acting between the holding portion 6 and the sheet 9 than in the vicinity of the insertion port 7 is formed in a portion separated from the insertion port 7. Accordingly, it is possible to realize the telephone 1 in which the seat 9 is not easily slipped out even when the seat 9 is easily inserted and the telephone 1 is tilted. Further, the shape of the convex portion 31 can be realized without an increase in cost if it is built in a mold for producing the casing of the main body 1.

Hereinafter, a second embodiment of the telephone of the present invention will be described with reference to FIG. Note that a description of common parts with the first embodiment is omitted.
In FIG. 7A, a convex portion 32 is formed in the direction BB ′ of the guide portion 10 in a direction parallel to the surface of the holding portion 6. FIG.7 (b) is sectional drawing in BB '. The convex portion 32 is formed in a direction parallel to the bottom portion 11 and is formed so as to narrow the gap with respect to the width direction orthogonal to the insertion direction of the inserted sheet 9. The gap between the tops of the two convex portions is formed to be equal to or narrower than the width direction of the sheet 9. As a result, the frictional force acting between the sheet 9 and the holding portion in BB ′ is higher than that in the vicinity of the insertion slot 7, and the same effect as in the first embodiment can be obtained.
Similarly to the first embodiment, in the second embodiment, the convex portions 32 do not have to be on both sides of the holding portion 6, and if the friction force is increased by narrowing the gap in the width direction of the sheet 9. It need not be convex. Needless to say, the protrusion 32 may be formed on the bottom 11 side.

Note that, as shown in FIG. 7C, a notch 33 may be formed in the sheet 9 at a position corresponding to the convex portion 32 of the holding portion 6. Since the notches 33 are fitted with the convex portions 32, the sheet 9 is more difficult to slide out.

Hereinafter, a third embodiment of the telephone according to the present invention will be described with reference to FIG. Note that a description of common parts with the first embodiment is omitted.
In FIG. 8, the number of the grooves 30 is different between the vicinity of the insertion port 7 and the portion separated from the insertion port 7. The number of the grooves 30 is reduced at a portion separated from the insertion port 7. The groove 30 is for reducing the frictional force acting between the sheet 9 and the holding portion 6. By reducing the grooves 30 in the spaced apart portions, the area where the sheet and the bottom 11 come into contact increases, and the frictional force increases. Thereby, the same effect as the first embodiment can be obtained. It should be noted that the same effect can be obtained even if the grooves in the separated portions are eliminated.

  FIG. 9 shows a modification of the third embodiment. In the portion separated from the insertion port 7, the direction in which the groove 30 is formed is shifted from the insertion direction of the sheet 9. If the groove 30 is formed in parallel with the insertion direction, the frictional force number becomes the smallest. Therefore, by shifting the formation direction of the groove 30 as in this modification, it is possible to increase the frictional force in the part separated from the insertion port 7. It becomes.

Hereinafter, a fourth embodiment of the telephone according to the present invention will be described with reference to FIG. Note that a description of common parts with the first embodiment is omitted.
In FIG. 10, the bottom 11 is curved in the vicinity of BB ′ separated from the insertion port 7. As a result, it is possible to increase the frictional force that acts between the sheet 9 and the holding portion 6 that are flat surfaces. In FIG. 10, the bottom portion 11 is curved in a convex shape toward the guide portion 10, but the present invention is not limited to this, and the same effect can be obtained by bending in the reverse direction or in a corrugated shape.

Hereinafter, a fifth embodiment according to the telephone of the present invention will be described. Note that a description of common parts with the first embodiment is omitted.
The effect of the present invention can be obtained, for example, by increasing the frictional force in the vicinity of BB ′ in FIG. In order to realize this, not only the structure of the holding portion 6 is changed as described above, but also the friction coefficient can be increased by changing the material of the portion separated from the insertion port 7 or the surface roughness.

The casing of the telephone 1 is generally made of ABS resin. In order to realize the fifth embodiment of the present invention, the portion of the holding portion 6 that is separated from the insertion port 7 may be formed of a material having a higher friction coefficient than that of the ABS resin. Examples of the material having a higher coefficient of friction than ABS resin include nylon, polyurethane, vinyl chloride, polystyrene, and the like, but are not limited thereto. If these materials are used for a part of the holding part, that is, the bottom part 11 or part of the guide part 10, the friction coefficient is increased and the frictional force is increased, so that the effect of the present invention can be obtained.

  Further, even if the material is not changed, the friction coefficient is increased and the frictional force is increased by processing the surface roughness of the bottom portion 11 or the guide portion 10 of the holding portion 6 so that the effect of the present invention can be realized. . The surface roughness may be adjusted with a mold, or may be performed by mechanical or chemical surface treatment after molding.

As described above, the present invention has a plurality of grooves 30 in the bottom portion 11 of the holding portion 6, and the frictional force acting between the holding portion 6 and the inserted sheet 9 is greater than that in the vicinity of the insertion port 7. This is realized by using a structure or material in which the portion spaced from the mouth 7 is higher.
A plurality of these embodiments may be combined.

  The present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the gist or concept of the invention that can be read from the claims and the entire specification. It is included in the technical scope of the present invention.

  The present invention can be suitably employed in a telephone.
