Description

[Detailed description of the invention] Industrial field of application The invention is used in Japanese typewriters in which the type storage can often be replaced with respect to the underframe depending on the type of printing.

Prior Art In the conventional Japanese typewriter, a typewriter in which the type storage is detachably attached to the underframe, and the type storage is locked to the underframe when installed, is the
Although the structure described in Japanese Utility Model Publication No. 9679, the one described in Japanese Utility Model Publication No. 15139-1983, and the one described in Japanese Utility Model Application Publication No. 105145-1988 have been disclosed, all of them had complicated structures.

Problems that the invention aims to solve: During printing, the type storage can be easily operated against the underframe depending on the type of type used for printing, and when the type storage is frequently replaced. To provide a loading/unloading device for a type storage in a Japanese typewriter, which can be attached and detached with an extremely simple structure and is devised so that the type storage does not move within the frame after installation. It is something.

Means for Solving the Problem This will be explained in detail by the embodiment shown in the figures. 1 is an underframe, and this underframe mainly has an inner frame 2 inside as shown in FIGS. 1, 3 and 4. A front frame 4 having a substantially V-shaped groove 3 on the other side, a front frame 5, a left frame 6 that connects the inner sides of both ends of the front frame 4 and the front frame 5, and the left frame. Right frame 7 with a lower height than 6
The upper part, the lower part, and the upper part of the right frame 7 are open respectively, and one side of the front frame 5 in the longitudinal direction (in the left-right direction in FIG. 1) is opened. A handle 8 for operation is integrally fixed to the near center (on the near side). 9 is a large number of letters 1
0 is a type storage housed in a predetermined arrangement, and the outside of the front frame 11 (the front side in FIG. 5) and the outside of the front frame 12 (the front side in FIG. 5) are ,
For example, an elastic engagement body 1 made of material of a polymer compound
3 are provided protrudingly by a method such as embedding. Reference numeral 14 designates a knob for operating the type storage 9, and this knob 14 mainly has a handle 15 bent approximately 90 degrees to the right in the same figure, as shown in the second figure.
Each of the engagement pieces 16 is formed by bending one (front in the figure) free piece part approximately 90 degrees to the other (front in the figure), and the engagement piece part The inner side (left end in the figure) of the protrusion 17 formed at one end (the right end in the figure) of the projection 16 is connected to the upper right edge 7' of the right frame 7 of the tapered underframe 1. A matching inclined surface 18 is provided. And this pickle 1
4 is integrally fixed to the outer side (on the right side in the figure) of the right frame 19 of the type storage 9 in the longitudinal direction (back and forth direction in FIG. 1) at approximately the center with a screw 20.

Therefore, in order to attach the type storage 9 to the underframe 1, while lifting the knob 14 slightly upwards using the handhold 15, the front frame 4 and the front frame are removed from the opening 7'' of the right frame 7 of the underframe 1. After inserting the engaging body 13 into the inner frames 2 and 2 between the frames 1 and 5 against the elasticity of the engaging body 13, the knob 14 is inserted into the inner frame 1 of the frame 1.
All you have to do is press it down toward the right frame 7 of . Then, the type storage 9 can be moved to the engaging body 1 provided on the front frame 11 thereof.
3 and the inner surface 4' of the front frame 4 of the underframe 1, and the engagement body 13 provided on the front frame 12 of the type storage 9 and the inner surface 5' of the front frame 5 of the underframe 1. The underframe 1 without any movement in the front-rear and left-right directions. (FIGS. 6 to 9 show the state during this period.) Furthermore, by operating the type storage 9 in the opposite manner as described above, the type storage 9 can be loaded and removed from the underframe 1. .

Effects of the invention As mentioned above, this invention has been applied to the front frame 11 of the type storage 9
and the front frame 12, elastic engaging bodies 13 are provided which engage with the inner surface 4' of the front frame 4 of the underframe 1 and the inner surface 5' of the front frame 5, respectively. It has an extremely simple structure in that the knob 14 fixed to the frame 19 is provided with an engaging piece 16 having an inclined surface 18 that engages with the right upper edge 7' of the right frame 7 of the underframe 1. , the type storage 9 is inserted through the opening 7'' of the right frame 7 of the underframe 1 onto the respective inner frames 2, 2 between the front frame 4 and the front frame 5 of the underframe 1 against the elasticity of the engaging body 13. Then, by the extremely simple operation of pushing down the knob 14 toward the right frame 7 of the underframe 1, the type storage 9 is moved to the right frame 1 of the underframe 1.
In addition to being able to be installed without any movement in the back and forth and left and right directions within the underframe 1, the type storage 9 can be easily moved from the underframe 1 by operating the type storage 9 in the opposite directions as described above. 9 can be attached and detached, which is extremely convenient when frequently replacing the type storage 9 with respect to the underframe 1 depending on the type of type used for printing during printing. As mentioned above, it is simple and easy to manufacture, and its use has extremely great practical effects.

The above description has mainly been about an embodiment in which the top of the right frame 7 of the underframe 1 is open and the right frame 19 of the type storage 9 is provided with a knob 14 having an engaging portion 16.
Even if the underframe 1 and the type storage 9 are configured with the right and left sides opposite to those described above, and even if the engaging body 13 is provided on the underframe 1 instead of the type storage 9, the present invention will still work in the same manner as described above. can be carried out.
