Abstract

PURPOSE:To save the consumption of ink as well as enable a printer to be used for long length of time with only one-time supply of ink by providing an outflow mechanism which allows a given amount of ink to flow out of a supplyer in response to the thickness of an object to be printed. CONSTITUTION:When a card 2 is sent between a feed roller 12 and a pinch roller 13, the roller 13 moves upwards as much as the thickness of the card 2. The first L-shaped rotator 21 is turned through a fixed angle around a pin 20, and the second L-shaped rotator 22 coupled with the rotator 21 is turned through a fixed angle around the pin 20 and its upper part is moved upwards. A supply port 10 is opened and ink flows out through a supply tube 11 to an ink roller 7. Each time the card 2 passes between the roller 12 and the roller 13, ink in the ink pot 9 can thus be supplied to the ink roller 7.

Next, the printing device l is provided with a feeding mechanism that sends the card 2 to the printing mechanism 3 .

The feed mechanism consists of a feed roller 12 and a pinch roller 13 placed above the feed roller 12.

The pinch roller 13 is biased to rotate clockwise by the counterclockwise rotation of the feed roller 12, and is biased by being sensitive to the thickness of the card 2 taken in between it and the feed roller 12.・It moves upward.

Now, the printing device 1 has an outflow mechanism that allows a predetermined amount of ink to flow out from the ink pot 9.

The outflow mechanism includes an actuation mechanism 14 and a second part of the actuation mechanism 14.
The valve mechanism 15 whose upper part 16 is fitted to the upper part of the L-shaped mouth member 22 is provided.

An upper portion 16 of the valve mechanism 15 projects outward from the upper surface 17 of the ink pot 9, and the other portions are housed in the ink pot 9. The valve mechanism 15 is connected to the upper surface 17 of the ink pot 9.
It is attached so that it can slide vertically. Furthermore, a valve 18 is arranged at the bottom of the valve mechanism 15. This valve 18
is disposed at the supply hole 10 portion of the ink bot 9, and the supply hole 10 is brought into an open state or an open state when the l2 portion 16 of the valve mechanism 15 moves downward.

- On the other hand, the actuating mechanism 14 includes a first L-shaped intermediary member 21 whose end on the do side is engaged with the shaft of the pinch roller 13 and whose bent portion is pivotally connected to the base 19 with a pin 20; A second L-shaped opening member 22 whose lower tip is engaged with the 1-side light end of the L-shaped interlocking member 21 and whose bent portion is pivotally connected to the base 19 with a pin 20. .

In the printing apparatus l configured as described above, the valve 18 of the valve mechanism 15 keeps the supply hole 10 of the ink bot 9 open until the card 2 is taken in between the feed roller 12 and the pinch roller 13. and the ink roller 7 through the supply pipe 11.
The outflow of ink sent to the area is stopped.

Next, when the card 2 is taken in between the feed roller 12 and the pinch roller 13, the pinch roller 13, which is in sliding contact with the feed roller 12, responds to the thickness of the card 2 and Move 1 unit.

As a result, the do side end of the first L-shaped interlocking member 21 engaged with the shaft of the pinch roller 13 is pushed upward, and the first L-shaped intermediary member 21, which is pivotally connected to the link base E9, is pushed upward. The rotating member 21 rotates at a certain angle around the pin 20, and this first

The pinch roller 13 remains open until the card 2 passes between the pinch roller 13 and the pinch roller 13, and as the card 2 passes, the pinch roller 13 returns to its original position.
Accordingly, the first L-shaped rotating member 21 and the second L-shaped opening member 22 are restored to their original positions. And the valve mechanism 15
The second part of the supply hole 10 moves downward to close the supply hole 10.

In this way, each time the card 2 passes between the feed roller 12 and the pinch roller 13, ink from the ink bot 9 is supplied to the ink roller 7, and the ink roller 7 applies ink to the outer peripheral surface of the marker roller 5. Evenly distributed.

A large number of cards 2 that have passed between the feed roller 12 and the pinch roller 13 are taken in by the take-in roller 6, and marks are sequentially printed by the marker roller 5.

The embodiments have been described above, but as moving members,
It is sufficient to have a member that moves in one direction in response to the thickness of the printed material only when the taken-in printed material passes, and the position of the ink supply section can be changed and the ink supply section can be moved from one place to another with one link. A fixed amount of ink may be flowed out.

Furthermore, the material to be printed is not limited to a card-like material, but may also be a large plate-like material.

In this case, the supply pipe may be formed thin. The printing is not limited to mark printing, but may also be character printing.

[Effects of the Invention] As is clear from the explanations below, the printing apparatus according to the present invention includes a feeding mechanism that sends the printing material to the printing mechanism, a supply section that supplies ink to the printing mechanism, and a feeding mechanism that feeds the printing material to the printing mechanism.
