Description

[Detailed Description of the Invention] The present invention relates to a double printing device equipped with two printing hammers, and in particular, the first printing hammer of the two printing hammers is always linked to a solenoid for normal printing operation. In addition, the present invention is characterized in that the other second printing hammer can be activated or stopped in conjunction with the first printing hammer by a user or a mechanical or electrical command.

When printing the time on a card using a time recorder, special indications such as leaving early or overtime may be printed in the printing field of the card at the same time as the normal time stamp.

Such special indications are printed using a special printing hammer provided separately from the one for printing the time stamp. Therefore, this type of time recorder has a double printing mechanism with two printing hammers, one for normal use and one for special use. is used.

These printing hammers are operated by a solenoid that operates based on a printing command, but printing hammers that perform special printing do not operate all the time, but need to be activated only in predetermined cases. It is not possible to operate the printing hammers of a book in constant cooperation.

A quick way to make the two printing hammers perform different operations is to use two solenoids to operate each printing hammer, but this method requires a complicated structure and is costly. It gets expensive.

In view of the above points, the present invention is configured so that each of the two printing hammers can be operated by one solenoid, and in particular, the printing operation of the printing hammer for special printing is controlled only in predetermined cases. It is an object of the present invention to provide a double printing device which is devised so as to be able to operate printing or, conversely, to stop printing in cooperation with a printing hammer.

To explain the present invention in more detail based on the description shown in the drawings, 1 is a frame to which the device of the present invention is attached, and 2 is a solenoid.

Reference numeral 3 denotes a mounting shaft installed between the left and right mounting walls 1a and lb arranged in parallel on the frame 1, and a rotating body 4 having a plate structure with one side attached to the plunger 2a of the solenoid 2 rotates on the shaft 3. It is attached freely.

Reference numeral 5 denotes a first printing hammer having a lower end attachment portion 5a rotatably attached to the attachment shaft 3, and a pressing body 6a of a first adjustment screw 6 screwed onto the rotary body 4 so as to be able to advance and retreat on the bottom surface of the flat end portion. When the solenoid 2 operates and the rotating body 4 rotates, the pressing body 6a presses the bottom side of the first printing hammer 5.

When the first printing hammer 5 is pressed by the pressing body 6a, the upper end side, that is, the hammer rubber 5b side hits the type wheel 7 side using the mounting shaft 3 as a fulcrum, and the card (
(not shown) can be stamped with time, etc.

Next, reference numeral 8 denotes a second printing hammer whose lower end 8a is rotatably attached to the mounting shaft 3, and the whole is formed into a frame shape, and the upper end of the switching lever 9 is rotatably mounted.

Further, on the bottom surface 9a of the switching lever 9, a second adjusting screw 1 is screwed onto the rotating body 4 side in line with the first adjusting screw 6.
0 is pressed against the pressing body 10a, and when the rotary body 4 is rotated by the solenoid 2 and the pressing body 10a presses the bottom part 9a of the switching lever 9, the second printing hammer 8 is pressed against the first printing hammer 8. The first printing hammer 8 rotates together with the printing hammer 5 about the mounting shaft 3 as a fulcrum, and hits the upper end of the hammer rubber 8C side against the type wheel 7 side.
Special markings such as leaving early or overtime can be stamped alongside the time markings.

The switching lever 9 corresponds to the intermediate interlocking member shown in the claims of the utility model registration, and controls the operation and stopping of the second printing hammer 8.

That is, a rotating piece 9b projects from the upper end of the switching lever 9, and a pressing shaft 11a attached to the lower end of the operating lever 11 can be freely pressed against the rotating piece 9b.

The actuating lever 11 is mounted on a mounting plate 12.1 arranged parallel to the frame 1.
It is rotatably attached to a shaft 12a installed between the two,
An operating cam plate 13 is fixed to the upper side.

Although not specifically shown, the actuation cam plate 13 has a convex portion and a concave portion formed therein, and a card pocket (not shown).
is located near.

A freely operable adjustment plate is attached to the card pocket, and the plate is provided with a piece that presses the cam edge of the cam plate 13.

The piece presses the convex portion of the normal operating cam plate 13 to hold the operating lever 11 and the pressing shaft 11a in the rotational state shown in FIG. 11a presses the entire switching lever 9 to the second position with the shaft 8b as the fulcrum.
The lever 9 is rotated to the state shown in the figure, and the bottom surface 9a of the lever 9 is pressed against the pressing body 1.
0 I have employees leave work within the pressure range of a.

Therefore, even if the solenoid 2 operates and the rotating body 4 rotates, the second printing hammer 8 does not operate, and only the first printing hammer 5 performs printing as shown by the imaginary line in FIG.

In order to operate the second printing hammer 8, it is sufficient to insert the aforementioned piece into the recess of the operating cam plate 13 and release the pressure on the switching lever 9 side by the pressing shaft 11a.

When the switching lever 9 becomes free, the lever 9 is rotated to the state shown in FIG. 3 by its own weight and the action of the return spring 14, and the bottom portion 9a is positioned within the pressing range of the pressing body 10a.

When the rotary body 4 is rotated by operating the solenoid 2 in this manner, the second printing hammer 8 and the first printing hammer 5 operate printing together as shown in the imaginary line in FIG. 3 via the switching lever 9. death,
Special symbols can be engraved on the card.

Note that the above-mentioned actuating means for the actuating lever 11 is an example of implementation, and for example, the actuating lever 11 may be moved by various other electrical or mechanical means to control the actuation of the second printing hammer 8. Of course it's good too.

As described above, according to the double printing device of the present invention, the first
While the printing hammer can perform time stamping etc. each time based on the operation of a solenoid, the second printing hammer operates together with the first printing hammer by switching the switching lever which is an intermediate interlocking member. It is possible to freely switch between operation and stop, such as printing when the solenoid is activated, or stopping and not printing regardless of the operation of the solenoid. It is suitable for implementation in the printing mechanism of a time recorder that can print at the same time as printing, and in particular, since both printing hammers can be operated by one solenoid, the structure can be simplified and manufacturing costs can be reduced. It also has practical effects.
