It has a movable contact link and a fixed contact (to) which are brought into a conductive state when pressed and switched to the manual side, or rendered non-conductive when the press is released.

In addition, in the figure (73 is a slit-shaped insertion hole (a taper part that makes it easier to push into 41) G4 is a paper sheet S4 that is in the OFF state when the lid member αa is removed and is in the ON state when it is closed. A paper detection switch, σe, is provided on the side of the first drive gear C17), and is set to be in the on state when the paper G4 is in contact with it, and in the off state when the paper σ4 is not in contact with the paper. A gear interlocking switch consists of a recess (71) and a movable contact that comes into contact with the fixed contact when it falls into the recess (71) and escapes from the fixed contact. At the exit, SS is the paper guide, □□□ is the paper tray, (Funds) is the ink vat (ink refill window for 4th column, and the illusion is the transparent lid attached to the ink vat (Funds).

That is, in the above embodiment, first, the lid member (1) is removed and the drum 0I is taken out, a stamp (to) is attached to the drum G3 that has been taken out, the drum (to) is put back in, and the lid member (2) is closed. Then, operate the automatic/manual switching button 61) to the manual side, and after this operation, insert the paper G4 into the recess (4) and insert the leading edge of it into the drum through the paper insertion slot (7). (31 and Vintyroll C?1) and the non-slip rubber (LgJ and Vintyroll r2υ, inserted between them,
Next, the manual pushbutton is pressed down and released, and the electric circuit shown in FIG. Since the paper detection switch σQ is in the on state, the motor circuit forms a closed loop and the motor starts rotating, and this start causes the movable contact 0 of the gear interlocking switch (3) to move out of the recess σ9. The switch comes into contact with the fixed contact wire of the σ force, and this contact is maintained before the manual push button U is released, and the drum G! I is in a rotating state, and when it rotates once in this way, the movable contact σ frame of the gear interlocking switch σ sword sinks into the recess 0 and separates from the fixed contact [F]O, opening the closed loop and stopping the drum GI. . In this way, when the drum C (l) rotates once, the stamp surface of the stamp □□□ is lightly pressed against the circumferential surface of the ink bat 03, and the ink is adhered to the stamp surface, and the paper (74 is removed from the rubber stopper U). The sheet σ4 is pressed against the ink-adhered stamp surface by the vinyl roll Cυ and printed, and the paper 0 is also conveyed by the rubber stopper fi.
It is sent out from the discharge port [F]υ due to the pinching and feeding action of the pinch roll 121J and the pinch roll 121J.

That is, by switching the automatic/manual switching button t61) to the manual side, inserting the paper σ, and pressing the manual push button, the outer circumference of the drum 09 can be changed to a shorter paper σ.
4 can be transferred. If the outer circumference of the drum (to) is long, the drum 09 will stop with the long part remaining between the drum 01 and the vinyl roll (2'JJ). All you have to do is press the push button (goods) again to release it.

In addition, another way to use it is to automatically
Operate the manual switching button 6υ to the automatic side to turn it on, and after the operation, insert the paper σ4 into the recess (4) and pass the tip of it through the paper insertion slot (7) to the drum GL and the pinch □-rule Qυ. The safety switch (79 is in the on state) is inserted between the rubber stopper and the pinch roll r2υ, and the safety switch (79 is in the on state)
When the paper detection switch σQ is turned on by inserting →, a closed loop of the motor circuit is formed and the drum (39
) is in a rotating state, and with the start of this rotation, the movable contact decoy of the gear interlocking switch (c) escapes from the recess σ9 and comes into contact with the fixed contact bar of the switch (5), and when it rotates once in this way, the gear interlocking switch The movable contact σ of σD enters the recess σ9 and separates from the fixed contact, thereby opening the closed loop and stopping the drum. In this way, the direction of the stamp ① is transferred and sent out from the discharge port @υ in the same manner as described above. In other words, continuous transfer can be performed by repeatedly inserting the sheet σ after switching the automatic/manual switching button 61) to the automatic side. If the paper (74) is long around the outer circumference of the drum, even if the gear interlocking switch σD turns off in the middle of each revolution, the paper detection switch σe remains on. Because of this, the rotation of drum 09 does not stop until the paper σ◆ runs out, and it always returns to position 1, which is the starting point of the next transfer operation.
It is a struggle to rotate and stop.

[Action] and [Effect of the invention]

As described above, the present invention includes a drum having a plurality of insertion holes (49) arranged vertically and horizontally at equal intervals in the peripheral wall, and a convex stamp made of a soft plastic having elasticity.

The reverse side of the stamp □□□ has a large number of pipe-shaped insertion legs (to) that are integrally arranged at equal intervals vertically and horizontally, and the pipe-shaped insertion legs (to), such as strainers, are inserted into the insertion holes (41). The stamp ■ is removably fixed to the drum 09 by inserting it in a slightly collapsed state, so by removing the wedge-shaped insertion leg (to) from the insertion hole Ol, the stamp ■ can be inserted. The drum C31
It can also be removed from the drum C31, and the seal can be removed from the drum C31□
Installation of □□ is possible by pushing the pipe-shaped push-in leg (to) into the insertion hole OI.

In other words, the size and position of the insertion legs on the back side of the stamp □□□ are very easy to attach and detach from the drum C31.
If you prepare a large number of stamps with different stamped faces, you can arbitrarily and easily add, reduce, or replace the number of stamps, or change the vertical and horizontal orientation by replacing them. It is useful to have a self-container, and there is also an insertion hole (4
9 is made into a slit shape, so the installed stamp ■ can be repositioned by the slit-shaped insertion hole (4cJI), making it easy to use, and the pipe-shaped insertion leg (to) When it is inserted into the hole (41), the insertion hole (4) in the pipe-shaped push-in 8!llIgB appears to have expanded on the back side (see Figure 3), so it can be removed easily. Not only is there no danger, but the pipe-shaped push-in leg egg is in pressure contact with the incisal edge surface of the slit-shaped insertion hole (4I) due to the repulsive force existing in the slit-shaped insertion hole (4I), and the friction is large, so the position may shift. Moreover, according to the present invention, the printing material is made of elastic soft glass.

When the paper Cl4) is pressed against the stamp surface by the vinyl roll Qυ, the stamp □□□ is slightly compressed and acts as a cushioning material, making beautiful printing possible. It has structural advantages such as not requiring cushioning material such as sponge on the back side, and since the seal has good flexibility, it fits well when attached to drum 09 and is extremely easy to use. It has the following effects.
