Description

[Detailed Description of the Invention] The present invention has been devised so that each type is brought into close contact with each other, and insertion into the type bar and drop of the type storage from the type bar can be carried out extremely well. It is something that

Next, to describe this in detail with reference to the embodiment shown in the figure, 1 is a type storage, and the bottom plate 2 of this type storage has an interval t approximately equal to the length and width of the type 3, which will be described in detail later. Holes 4 for pushing up the type are bored vertically and horizontally at the holes 4 and T. Reference numeral 5 designates a cylinder having a substantially hemispherical tip that serves both as a guide for the typeface 3 and as a partition. It is erected so as to be located approximately in the center, and is provided with a slight interval S between the outer circumferential edge of the hole 4 and the outer circumferential edge of the column 5, and the bottom plate 2 Height from top surface h
is made slightly lower than the height H from the bottom surface 6 of the type 3 to the lower part 8 of the block 7 to form the type storage 1. Therefore, the printed word 3 is
The shape and structure from the face 9 to the net 7 are the same as those of conventionally known ones, but the structure below the net 7 is different, mainly as shown in the first and fourth figures. Cut off the lower four corners toward the center to form surfaces 10 ₁ ... 10 ₈ ,
The surfaces 10 ₁ .
10 ₈ and the bottom surface 6, a surface 12 is also removed between the surface 10 ₁ ... 10 ₈ and the net 7 part, and the surface 1
The spacing S ₁ between 0 ₁ and 10 ₅ and the spacing S ₂ between surfaces 10 ₃ and 10 ₇ are the spacing S ₃ and S ₄ between the columns 5 and 5 diagonally facing each other in the type storage 1. It is designed to be slightly smaller than the

In the configuration described above, in order to store the type 3 in the type storage 1, the type 3 is stored from the upper side of the type storage 1.
The planes 10 ₁ , 10 ₅ are formed between the cylinders 5 and 5 which face each other in an oblique direction while the direction of the thread 7 is directed in a predetermined direction.
and 10 ₃ and 10 ₇ are inserted next so that they are positioned respectively. Then, the surface 12 of each type 3 mainly forms the cylinders 5, 5 as shown in the third figure.
They are positioned so as to be engaged with and received by the type characters 3, and are housed in close contact with each other above the bases 7 of the respective type characters 3. In this state, the type 3 is supported by the adjacent type 3 and the cylinders 5, 5 and does not tilt. Therefore, even if the type bar 13 is pushed up into the type insertion hole 14 of the type bar 13 from below (from the front in Fig. 5) into the hole 4 for stamping with a type stopper rod (not shown), the type bar 13 is tilted. In addition to this, when the type 3 returns to the type storage 1 after stamping is completed, the type 3 is mainly pushed up by the adjacent type 3 as shown in Figure 5.
Since the typewriter 3 is guided back by the cylinders 5, 5, etc., the return can be carried out easily and reliably, and is extremely efficient. In addition to being able to reduce the size of the polymer compound, its structure is simple: holes are bored at predetermined intervals in the bottom plate, and cylinders are placed upright at the four corners of the outer periphery of the holes. In addition to the fact that it can be manufactured easily and in large quantities at low cost by molding,
Compared to those described in Publication No. 1691 and Publication No. 17111 of 1981, the hole for raising the type in the bottom plate can be made larger because there is no slope on the peripheral wall of the hole in the case. Therefore, there are many excellent effects such as no damage to the peripheral wall of the hole caused by the type projecting rod.
