Description

[Detailed Description of the Invention] The present invention relates to a hand puncher that can manually punch holes for reading in 80-column cards used in computers.

When punching (issuing) a large amount of 80-column cards, there is no problem as the punch is automatically issued using a computer-operated automatic puncher, but when punching a small amount on-site,
At present, there is no suitable puncher for use in issuing revisions, and even if there is one, it has the disadvantage that it is extremely expensive and cannot be used at low cost.

Therefore, the present invention aims to provide a hand puncher for 80-column cards which is capable of punching holes in 80-column cards with extremely simple operation and accuracy, and which is devised so that it can be manufactured at an extremely low cost. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the overall dramatic view shown in FIG. 1 and the sectional view shown in FIG. 2, reference numeral 1 denotes a base, and 2tl'1 indicates a machine frame provided approximately at the center of the upper surface of the base 1.

The top surface of the base 1 is the surface in front of the machine frame 2 in the center, that is, the surface on the left side in FIG. 2, which is the insertion surface 1a of the 80 column card C shown in FIG. Further, the rear surface, that is, the right side surface is a feeding surface 1b on which card feeding is performed by a clamp described later, and both surfaces 1a.

On both the left and right sides of 1b, there are guide edges lc for guiding the card C,
lc is provided protrudingly.

2' is a card insertion slot opened on one side of the machine frame 2, 3ri
The mounting shaft installed horizontally inside the machine frame 2 is shown.

4a to 41V'i Punch levers for X, Y, and 0 to 9, a total of 12 punch levers, are placed on the top of the feed surface 1b of the base 1 in order in one direction (width direction) of the card C in column 80. The tips of the punch levers 4a to 41 are inserted into the machine frame 2 and rotatably connected to the mounting shaft 3, respectively.

4... is a push button attached to the hand part of each punch lever 4a to 41, and these buttons have X, Y, etc.
The symbols 0 to 9 are displayed as shown in FIG.

Each of the punch levers 4a to 41 inserted into the machine frame 2 has an 80 inserted into the insertion passage 2a of the machine frame 2 on the tip end side.
A punch 5 for perforating the column card cK is attached to each of the punches 5, and the punch lever is always supported upwardly between the punch stand 6 provided in the machine frame 2 and the bottom of each punch lever 4a to 41. Coil springs 7 are interposed respectively.

In FIGS. 2 and 3, reference numeral 8 denotes a feed frame rotatably attached to the mounting shaft 3, and a driven frame 8a provided on the feed frame 8 protrudes below the bottom surface of each of the punch levers 4a to 41. 4c to 4 for punch levers 0 to 9.
1 is pressed and rotated, the driven frame 8a is pushed and the entire feed frame 8 rotates clockwise in FIG. 2 around the mounting shaft 3. .

However, when the punch levers 4a and 4b for X and Y are pressed and rotated, a notch 8a' is formed in the upper edge of the driven frame 8a so that the feed frame 8 does not rotate. .

8bIIi A feed lever is vertically installed on one side of the feed frame 8, and a feed pawl 9 is attached to the lower end of the lever 8b suspended within the base 1.

This is a guide shaft installed in the longitudinal direction inside the 10t-J base 1. An operating frame 11 is attached to this shaft 10, which is movable in the insertion direction of the l1i80 column card C, that is, in the column direction. The rack 12 is installed.

Rack 12Ktd The feed claws 9 are engaged, and the feed frame 8
When the card rotates back and forth once, the feed claw 9 feeds the rack 12 by one pinch, and sends the rack 12 by l pinch (l configuration) in the column direction of the card C along the overall guide shaft 10 of the operating frame 11. There is.

Furthermore, in FIGS. 2 and 4, the reference numeral 13 indicates a clamp that clamps the leading edge of the 80-column card C that protrudes from the insertion passage 2a onto the feeding surface 1b. A substrate 1 attached to one end of the operating frame 11 via 13a.
3bri, which protrudes horizontally from the elongated hole 1b' to the upper surface of the feeding surface 1b.
d is rotatably attached, and the board 13b and the rotating plate 13
A spring 13e interposed between d constantly presses a clamping piece 13f formed at the tip of the rotating plate 13d to a clamping die 13g attached to the front surface of the mounting plate 13a.

The leading edge of the column 80 card C is clamped between the clamping piece 13f of the clamp 13 and the clamping die 13g, and this clamping operation is performed by a clamp lever connected to the end of the rotating plate 13d. 13'.

Next, in Fig. 2, Fig. 5, and Fig. 6, 14 is the outer end 1.
4a protrudes from the outer surface of the base 1, and the inner end 1 is formed into two prongs.
4b and 14c are respectively the lower side of the feed claw 9 and the rack 1.
When this lever 14 is rotated in the direction of the arrow in FIG. 6 using the release lever protruding from the bottom side of the stopper 12& for 2, the inner ends 14b and 14c will release the feed pawl 9 and the stopper 12a from the rack 12 and release the operating frame 11. The clamp 13 can be freely moved in the column direction along the elongated hole 1b', and the operating frame 11 can be automatically returned to its original position by the action of the winding spring 15.

In addition, in FIG. 2, 16 is a pointer attached to the operating frame 11.The position of this pointer 16 is indicated by a scale attached to the top surface of the base 1.
(not shown), the amount of movement of the 80 column card C in the column direction by the clamp 13 is known, and the punch 5 can punch a hole in the desired column.

Since the present invention has the configuration as described above, the leading end side of the 80 column card C is inserted into the insertion passage 2a of the machine frame 2 along the insertion surface 1a.
Lever 13
' to clamp it to the clamp 13 on the feeding surface 1b side.

Thereafter, by pressing any one of the punch levers 4c to 41 for O to 9 as desired, the punch 5 can punch a hole C' in the desired position of the card C in column 80.

In conjunction with this drilling work, the feed frame 8 rotates and the feed claw 9
Since the rack 12 is pulled to the left in FIG. 2, the punch lever is released and the coil spring 7 is pulled.
pushes the punch lever back to its original position and moves punch 5 to card C.
At the same time as the rack is pulled out, the return rotation of the feed frame 8 causes the feed pawl 9 to feed the rack 12 by l thickness, and the operating frame 11 can be moved by Kl pitches in the column direction (rightward in FIG. 2).

Therefore, the clamp 13ri integrally formed with this operating frame 11
The 80 column card C can be advanced one column to prepare for the next punch.

In short, with this invention, punch lever 4C-4 for riO-9
If you press any of the levers 1, the card cIlc hole will open, and if you release the pressure on the lever, you can automatically advance the card C by 1 column.If you continue this operation, the card C will be 80
This allows accurate drilling in the desired column of column card C.

In addition, in this invention, as mentioned above, the punch lever 4 for 0 to 9 is
When you press c~41 to make a hole, card C is advanced by one column for every l punch, but levers 4a and 4 for X and Y
When pressing b to punch, the feed frame 8 does not rotate and is not fed.

That is, X and Yri should never be drilled alone, but should always be drilled in combination with the numbers O to 9.

This hole is necessary to represent the Roman letters such as 1suX and YriABC... In combination with the numbers O to 9, for example, the Roman letters tl'1AldY and 1, 13 are combined as Y and 2, and so on. When the levers 4a and 4b of X and Y are operated first, the feed is not applied, and only when the levers 40 to 41 of O to 9 are operated next, the feed is heated and the card C is rammed with one force. You can move forward by a minute.

As described above, the present invention allows the punching or issuance of 80-column cards to be carried out extremely easily and accurately by manual operation, so it is suitable for use in on-site issuance of small quantities or amended issuance, and is suitable for use in culling. Since it does not use any electrical parts and has a simple structure, it also has the advantage of being able to be manufactured at a much lower cost than conventional ones, and its practical effects are extremely large.
