JPS609029Y2 - Header board indicating device for Japanese typewriters - Google Patents

Description

[Detailed explanation of the invention] This invention also applies to the case where the index board for character selection on the type board is tilted toward the user so that it is easy for the user to see.
Relating to a heading board indicating device for a Japanese typewriter that is devised so that it is possible to use a heading board on which heading characters are displayed at a pitch equal to the pitch of the type arrangement on the typeface, This eliminates the trouble of changing the pitch between the indicated characters on the index board depending on the degree of inclination of the index board.

Next, to explain this in detail with the embodiment shown in the figure, 1 is a machine base, 2 is a type plate, and this type plate accommodates a large number of printing type 3 in a predetermined arrangement at a predetermined pitch vertically and horizontally. ing.

The typeface 2 is mounted on the front side of the machine stand 1 (the upper right side in Figures 1 and 2) through a roller 4, etc., in the left-right direction (back-and-forth direction in Figure 2). It is mounted so that it can be slid a predetermined amount.

Reference numeral 5 denotes a carriage, and this carriage is provided with a key lever 6 for stamping operation, a type bar 7, etc., and is located above the typeface 2 at the front and back with respect to the machine base 1. Left-right direction (left-right direction and front-back direction in Figure 2)
It is suspended so that it can slide freely.

All of the above are the same as known ones.

8 is a heading board, and this heading board has a large number of heading characters 9 corresponding to the printing type 3 accommodated in the printing board 2 arranged in the same arrangement as that on the printing board. , with equal pitch.

This index board 8 is placed on the front side (first side) of the type board.
Attach the mounting bracket 10 and screws 11 and 11', etc. to the position opposite to the typeface on the right side in Figures 1 and 2. α angle in the example)
It is fixed in a tilted position.

12 is one side of the mounting bracket 10 (the front side in Fig. 2)
A handle for operating the type plate is provided on the handle, and the type plate 2 and index plate 8 can be moved integrally in the direction indicated by the arrow in FIG.

Reference numeral 13 is a pointer for indicating characters for a heading on the heading board, and the lower end thereof is formed into a tapered shape.

Reference numeral 14 denotes a support tube for the pointer, and this support tube is provided at the other end of a support rod 15 whose one end is fixed to the carriage 5.

Then, the pointer 13 is guided by the guide hole 16 of the support tube.
is suspended so that it can slide vertically (back and forth in Figure 1). (to the left in Fig. 1) from directly below, and at a position suitable for stamping, that is, the type insertion hole 17 of the type bar 7.
A support tube 14 and a pointer 13 are respectively provided to indicate the index character 9 on the index board 8 which corresponds to the type 3 located directly below.

This proposal has a structure similar to Naruko, especially the typeface 2 with an angle (7) that is half of the inclination angle α of the faceplate 8 with respect to the faceplate 8.
Since the pointer 13 is provided so as to be inclined from directly below toward the side (to the left in FIG. and the index board 8 correspond to the equilateral sides of an isosceles triangle with the pointer 13 as its base). Even when the index board 8 is tilted to make it easier for the user to see, Even if the pitch between the heading letters 9 on the heading board 8 is equal to the pitch between the letters 3 on the typeface 2, the pointer 13 ensures that the characters are indicated at the position suitable for printing. I was able to
Not only is the effect of completely eliminating the trouble of calculating and changing the pitch between the heading letters on the heading board 8 depending on the inclination angle of the heading board 8 extremely great, but the structure is also As described above, with respect to the index board 8, the pointer 13 is tilted from directly below toward the typeface 2 at an angle of - half of the inclination angle α of the index board 8, and the pointer 13 is tilted in the vertical direction with respect to its support tube 14. It is an extremely simple structure with a free rack that slides on the surface, and it is easy to manufacture, so the practical effects of its use are extremely large.

In the figure, reference numeral 18.18 indicates a screw for attaching the support rod 15.

Claims (1)

[Scope of utility model registration request] A heading board 8 is provided on the front side of the printing board 2, and is located downward from the horizontal direction on the front side of the printing board 2, and has characters 9 for the heading of each printing type indicated at positions corresponding to the positions of the printing characters 3 housed in the printing board 2. In a Japanese typewriter in which the typeface is inclined at an angle, the pointer 13 for indicating the heading characters of the heading board 8 is attached to the heading board 8 through a support tube 14 provided on the carriage 5. On the other hand, the index plate 8 is tilted toward the type plate 2 from the vertical direction at an angle of - half of the inclination angle α, so that it matches the type 3 on the type plate 2 at a position suitable for printing with the type bar 7. Headboard 8
An indicating device for a index board, which is positioned above the upper index character 9 and is freely suspended so as to slide up and down with respect to a support cylinder 14.
