Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement of a character selection fixing device in a character selection punching machine that punches out letters and numbers into paper or the like using a plurality of small holes.

[Conventional technology]

Conventional character selection and punching machines only utilized part of the character theory, and could not be used all around.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a character selection punching machine that can rotate a character wheel through 360 degrees using a simple mechanism and can utilize the entire circumference of the character wheel.

[Structure of the invention]

In order to satisfy the above object, the present invention is constructed as follows.

That is, the present invention provides a character selection punching machine of a type in which letters and numbers are expressed by a large number of punched holes. The operating lever is connected to the outer periphery of an elevating circular body supported by an operating arm, and is fitted with a coil spring in a recessed hole formed in the elevating circular body, and has a chevron-shaped tip. A set pin having an edge-like tip cut off is housed, and V-shaped notches with the edge-like tips are arranged in rows on the inner circumferential surface thereof in correspondence with each character forming hole of the character ring, and further annular operation is performed. This is a glyph selection fixing device for a title punching machine, in which a V-shaped notch and an arcuate notch are formed on the inner peripheral edge of the lever so that the edge-like tip of the set pin is rounded.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a character wheel selection and fixing device in a character selection punching machine according to the present invention will be described with reference to the drawings.

In Fig. i, reference numeral 1 denotes an operating arm whose intermediate portion is pivotally supported by a support shaft 25 on a bearing plate 3 attached to a rock stand 2, and a shaft 4 whose forked portion 8' at the rear end is rotated by a handle punch.
In addition, as shown in Figure 2, several circular letter rings 5
A support shaft 7 protruding from the elevating circular body 6 arranged on the outer periphery is engaged with the forked portion 8 at the tip of the operating arm 1, and the support shaft 25 is used as a fulcrum by the shaft 4 that moves by the operation of the handle punch. When the actuating arm 1 swings, the elevating circular body 6 and the character 5 descend to selectively lower the punching needle group (not shown) below the character ring 5 to remove the paper inserted into the paper mulberry insertion gap 9. This is to punch letters and numbers into the hole. It is a die block equipped with a group of 10' piercing needles, etc.

The above is a general description of a known character selection/cutting machine. However, in the present invention, each character 5 has an annular operating lever 1.
1 are brought into contact with each other (see FIGS. 3 and 4), and one arcuate notch 12 is formed in the green inner periphery of each character ring 5, as shown in FIG. A V-shaped notch 14 is provided on the inner peripheral surface corresponding to the hole 13.

Then, a coil spring 16 and a set pin 17 having a chevron-shaped edge-shaped tip 18 at the upper end are inserted into the recessed hole 15 formed in the elevating circular body 6, and the edge-shaped tip 18 is inserted into the arc-shaped notch 1.
2 and V-shaped deficiency 14 in common.
(See Figure 5) Also, the set pin 17 is a rotation stopper pin 19.
(see FIGS. 4 and 6), and its protruding ends are arranged in two vertical grooves on the left and right sides of the recessed hole 15. The annular operating lever 11 has a knob 21 and a protrusion piece 22 protruding from the knob 21, and a stopper is provided on the outer periphery of the letter row between the knob 21 and the protrusion piece 22 as shown in FIGS. 1 and 4. I have given out a piece of 23. [Operation of the Invention] When the knob 21 of the annular operating lever 11 is held and the operating lever 11 is turned until the guard piece 22 contacts the stopper piece 23, the set pin 17 is removed from the position of the arcuate notch 12.
The V-shaped notch 14 in the wheel is pressed down against the spring 16.
You will be free and free from it.

Therefore, the character theory can be freely rotated by hand, and when the desired character is located directly above the punching needle, the knob 21 of the operating lever 11 can be returned to its original position, and the edge-like tip 1 of the set pin can be set.
8 rises and enters notches 12 and 14 in common, and the character theory stops. [Effects of the Invention] With the configuration of the present invention, the character theory can be used all around, so the performance of this type of punching machine is improved compared to conventional ones.

In particular, in the case of the present invention, the edge-like tip of the set pin fits into the arc-shaped notch of the annular operating lever 11 as well as the V-shaped notch, so when resetting the operating lever, hold the knob and press the operating lever. By turning the set pin, the set pin can be smoothly pushed down against the coil spring due to the arcuate notch, and the set pin can be removed from the V-shaped notch and the ring can be reliably freed. In other words, it has the effect of being able to select and fix the character theory using an extremely simple mechanism.
