The ends of the rails 7a, 7b and the guide rails 8a, 8b are formed in a tapered shape so that the original plate 1 can be easily inserted into the plate making device 44 described later.

Next, a plate making apparatus 44 for making a plate on the original plate 1 will be described with reference to FIG. In FIG. 3, only the main part of the plate making device 44 is shown, and the other parts are not shown or described.

The main part of the plate making device 44 is mainly composed of a pair of driving roller 11 and driven roller 12, a platen roller 13, a thermal head 14, a gate 15, a leaf spring 16, a fixed side guide 17, a movable side guide 18, an original plate. It is composed of a detection switch 19.

The driven roller 12 and the thermal head 14 are arranged so as to come into contact with the rail 7b provided on the frame 3 of the original plate 1 and the printing surface of the heat-sensitive stencil sheet 2 respectively by a mechanism and a drive source (not shown). ing. Further, the platen roller 13 is arranged between the rails 7a of the original plate 1, and the thermal head 14 is pressed against the printing surface of the original plate 1 which is directly below the platen roller 13.

The gate 15 arranged so that the leading end side of the original plate 1 abuts is configured to be openable / closable by a drive source (not shown). Further, the movable side guide 18 and the fixed side guide 17 are configured to contact the guide rails 8b and 8a of the original plate 1, respectively, and the movable side guide 18 always moves the original plate 1 to the fixed side guide 17 by a predetermined force. It is urged in the direction.

The original plate detection switch 19 is configured so that the guide rail 8a pushes the lever of the original plate detection switch 19 when the original plate 1 is correctly inserted into the stamp device.

As shown in FIG. 4, the stamp device of this embodiment comprises an input device 41, a display device 42, a control device 43, a plate making device 44, a storage device 45, and a detection device 46.

The input device 41 is for inputting characters and functions using a keyboard. The display device 42 uses a liquid crystal display device, and displays a character or an operating state of the device according to a key input from the input device 41. The control device 43 is an interface part connected to a CPU and peripheral devices that control the entire stamp device. The plate making device 44 is the plate making mechanism described above. The storage device 45 includes a ROM in which an operation command of the CPU is written and a RAM for storing data. The detection device 46 is a part that performs input processing of the original plate detection switch 19 described above and other detectors not shown.

Next, the operation of the stamp device of this embodiment having the above configuration will be described.

First, at the time of plate making, the driven roller 12 and the thermal head 14 are initially released downward by a driving source (not shown), and the gate 15 is arranged at the position shown in FIG. When the original plate 1 is inserted in this state, the guide rails 8b of the original plate 1 are pushed by the movable side guides 18 with a predetermined force, and the original plate 1 is pushed to the position where the guide rails 8a abut the fixed side guides 17.

Then, the original plate 1 guided by both side guides of the plate making device 44 is inserted to a position where it hits the gate 15. At the same time as the original plate 1 hits the gate 15, the projection 10 provided on the original plate 1 gets over the plate spring 16 provided on the plate making device 44 side, so that the user can feel the click when the original plate 1 is inserted. I can tell. In this state, the guide rail 8a of the original plate 1 pushes the lever of the original plate detection switch 19 protruding from the hole provided in the fixed side guide 17, and the original plate detection switch 19 is turned on.

Next, a plate making operation is started by pressing a plate making key (not shown). When the plate making key is pressed, the control device 43 first confirms from the detection device 46 that the original plate detection switch 19 is in the ON state. If the original plate detection switch 19 is not turned on, it is judged that the original plate 1 is not inserted or the insertion state is abnormal, and the plate making operation is not performed, and the display device 42 displays the abnormality of the original plate 1 insertion.

When the original plate detection switch 19 is turned on, the gate 15 is lowered downward by a drive source (not shown), and at the same time, the driven roller 12 and the thermal head 14 are respectively placed on the rail 7b of the original plate 1 and the marking surface. It is pressed with a predetermined pressure to be in the state shown in FIG.

After that, the driving roller 11 is driven to rotate in the direction of the arrow and is energized to the thermal head 14 based on the signal corresponding to the desired image, so that the original plate 1 is conveyed while the heat-sensitive stencil sheet 2 surface is conveyed. To be perforated.

When the punching is completed, the thermal head 14 and the driven roller 12 are separated from the original plate 1 by a driving source (not shown), and a series of plate making operations are completed.

Finally, as shown in the conventional example of FIG. 8, the original plate 1 can be attached to the stamp member 120 to print.

Here, the processing of the plate making operation when the original plate 1 is inserted into the plate making apparatus 44 in the reverse direction will be described.

In the state where the original plate 1 is inserted into the plate making device 44 in the reverse direction, the lever of the original plate detection switch 19 is inserted into the recess 20 b provided in the original plate 1 with respect to the correct insertion state shown in FIG. In opposition, the lever is not pushed and the original plate detection switch 19 is turned off.

In this off state, the plate making operation is not performed as described above, and it is determined that the insertion state is abnormal, and the display device 42 displays the abnormality of the original plate 1 insertion.

Similarly, when the original plate 1 is inserted upside down into the plate making apparatus 44, the recess 20 a provided in the original plate 1 faces the lever of the original plate detection switch 19. Even when the original plate 1 is inserted upside down and upside down, the recess 20c provided in the original plate 1 faces the lever of the original plate detection switch 19. In either case, the detection state of the original plate detection switch 19 is off, and the plate making process is not performed.

As is clear from the above description, by using the original plate 1 and the stamp device according to the present embodiment, even if the original plate 1 is inserted into the plate making apparatus in the front-rear direction or upside down, Does not perform the plate making operation, so that the original plate 1 is not wasted and the meaningless plate making operation is not performed.

The present invention is not limited to the embodiments described in detail above, and various modifications can be made without departing from the spirit of the invention.
