DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording pen holding device which can be easily attached and detached.

[0002]

2. Description of the Related Art In a recorder for recording a measured value, an ink-written recording pen is used to record the measured value on recording paper. Recently, disposable pens are frequently used. The disposable recording pen is detachably held by a pen arm provided inside the recorder. When the ink runs out, the pen is detached from the pen arm and replaced with a new one. Also, disposable recording pens need to be replaced periodically. In these cases, the removal of the recording pen must be performed inside a working narrow recorder. Therefore, as a holding device for holding a disposable recording pen, a device that can be easily mounted for replacement and easily removable is required.

[0003] As a conventional holding device of this type, one having a structure as shown in Figs. 4 and 5 is known. In FIG. 4, reference numeral 10 denotes a disposable recording pen, which includes a pen tip 11 and an ink tank 12. Reference numeral 20 denotes a pen arm attached inside the recorder, and reference numeral 21 denotes a fixing bracket. In this holding device, the recording pen 10 is attached to the pen arm 20 from a diagonally lower side, and is fixed by a fixing bracket 21, but attaching and detaching from the diagonally lower side is troublesome. Becomes

In the holding device shown in FIG. 5, a groove 13 is formed in the upper part of the recording pen 10, and the recording pen is attached to the arm by inserting the tip of the pen arm 20 into this groove. . Although the apparatus shown in FIG. 5 is relatively easy to attach and detach, the recording pen becomes large, so that a space is required when the pen is multistage, or the recording lines are separated when using multiple pens. There is a problem to say.

SUMMARY OF THE INVENTION The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional pen holding device in a recording pen for ink writing, and its object is to make it small and inexpensive, and to make the detaching operation extremely easy. It is to provide an easy pen holding device.

[0005]

SUMMARY OF THE INVENTION The present invention has an elongated substrate made of stainless steel and has side plates integrally provided on both sides through a pair of legs. By applying a force inward to the sides, the central portions of the both side plates are curved so as to open each other, and when the recording pen is mounted, the central portions of the both side plates are curved inward so that the central portions of the both side plates are curved inward. It is to give power.

[0006]

According to the present invention, the central portions of both side plates made of stainless steel are curved by the principle of Peko, so that the recording pen can be attached and detached.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a configuration diagram showing an embodiment of a recording pen holding device according to the present invention. This holding device 30 is formed by bending a stainless steel material into a U-shaped cross section, and has a pen arm (not shown).
Used to attach to.

In this pen holding device, 31 is an elongated substrate, and 32 and 33 are side plates. The side plates 32 and 33 are formed integrally with the substrate 31 via a pair of legs 34a and 34b and 35a and 35b, respectively. The side plates 32, 33 are curved so that their central portions 32a, 33a are widened as shown in the figure. When the central portions 32a, 33a are pressed inward with fingers, the bends are opposite and the central portions are narrow. It is curved to become. Since the holding device 30 is made of a thin stainless steel material, the above-mentioned curved state is maintained as long as no force is applied from the outside. The bends toward the inside of the central portions 32a, 33a
When a finger is applied to the free ends 32b, 33b of the 33 inwardly, as shown by arrows in the figure, it returns to its original position, and the central portions 32a, 33a are curved so as to become wider as shown. This state is maintained unless a force is applied from outside. A semicircular protrusion 31a is formed at the center of the substrate 31, and holes 31b and 31c are formed on both sides of the protrusion 31a. The semicircular projecting portion 31a adjusts the distance of the substrate between the legs 34a and 34b and between the legs 34a and 35b so that the central portions 32a and 33a of the side plates 32 and 33 can bend. , 33 to reduce the distance. The holes 31b and 31c are used for positioning a recording pen described later.

FIG. 2 is a perspective view of a recording pen used in the holding device of FIG. In the figure, reference numeral 40 denotes a recording pen, which comprises a pen tip 41 and an elongated ink tank section 42. The width a of the ink tank portion 42 is slightly smaller than the width b of the substrate 31 of the holding device 30. Ink tank part 4
2 has a groove 42a for escape from the protruding portion 31a provided on the substrate 31 and a hole 3 also provided on the substrate 31.
1b and 31c are formed with projections (both are not shown in the figure), and step portions 42d and 42e are fitted on the side portions of the space portions 32c and 33c of the side plates 32 and 33 of the holding device 30. (42e is not visible in the figure)
Are formed.

The operation of attaching and detaching the recording pen in the recording pen holding device having such a configuration will be described below. When mounting the recording pen 40 on the holding device 30. When the recording pen 40 is detached from the holding device 30, the side plates 32, 33 of the holding device 30 are curved so that their central portions 32a, 33a are widened as shown in FIG. In this state, the recording pen 40 has its pen tip 41 directed downward in the drawing, and the ink tank portion 42 has a groove 42a formed on the bottom thereof and a protrusion formed on the substrate 31 of the holding device 30 by a protrusion. 31a and holes 31b, 3
It is arranged on the substrate 31 of the holding device 30 so as to be fitted to 1c. Thereafter, the side plate 3 of the holding device 30
When the central portions 32a, 33a of the two, 33 are pushed inward with fingers, the central portions 32a, 33a bend inward each other, and the side surfaces of the recording pen 40 are sandwiched by the narrowed side plates 32, 33. In this case, the step 4 formed on the side surface of the recording pen 40
2 d and 42 e are fitted into the spaces 32 c and 33 c of the side plates 32 and 33 of the holding device 30. As a result, the recording pen 40 is mounted and held on the holding device 30 without coming off due to vibration or the like. FIG. 3 shows the holding state. When the recording pen 40 is detached from the holding device 30. Free ends 32b, 33b of side plates 32, 33 of holding device 30
When the inward force indicated by the arrow in FIG. 1 is applied by a finger, the side plates 32 and 33 are curved so that the central portions 32a and 33a become wider. Thereby, the recording pen 40 can be easily removed from the holding device 30.

[0011]

According to the present invention, it is possible to obtain an extremely inexpensive holding device which is made of a stainless steel material and has a function of a lever so that the recording pen can be attached and detached with one touch. As described above, since the recording pen can be easily attached and detached, it can be easily exchanged even in a narrow recorder when the recorder is operating (at the time of recording). Even in such a case, it is possible to easily bring the adjacent pens close to each other, so that it is possible to obtain a pen holding device in which records can be easily read.
