The stopper 142 is for allowing the stopper 142 to freely slide in the left-right direction in the drawing. A solenoid 144 is used as a drive source for sliding the stopper 142. Then, by energizing or demagnetizing the solenoid 144, the stopper 142 is slid between a position where the two lift wires 140 are prohibited from rotating and a position where the two lift wires 140 are rotatable.

Next, the structure of the stamp device as a whole is shown in FIG.
Will be explained.

As shown in FIG. 6, the stamp device is composed of an input device 41, a display device 42, a control device 43, a plate making device 44, a storage device 45, and a mounting device 46.

The input device 41 receives characters and function inputs from the keyboard 41a or the like. The display device 42 uses a liquid crystal display 42a, and displays the input characters or the operating state of the stamp device according to the input from the keyboard 41a or the like.
The control device 43 includes a CPU that controls the entire stamping device and an interface portion connected to peripheral devices.
The plate making device 44 uses the plate making mechanism described above to produce the original plate 1.

The storage device 45 includes a ROM in which the program shown in the flowchart of FIG. 7 is written and a RAM for storing the prepress image data. The mounting device 46 is a mounting mechanism portion that mounts the original plate 101 after plate making on the stamp member 120, and includes the lift wire 140, the shaft support portion 141, the stopper 142, and the solenoid 144 described above.

Next, the original plate 1 by the stamp device of this embodiment
The operation from 01 plate making to mounting will be described with reference to the flowchart of FIG.

Here, it is assumed that the punching image data input to the stamp device has been completed and the operation command from the plate making key 22 has been accepted.

When the operation command for plate making is received, the control device 43, based on the signal from the original plate detection sensor 19, outputs the original plate 10.
It is determined whether 1 is set in the plate making device 44 (S101). If not installed (S10
1; No) A display is displayed on the display device 42 so as to mount the original plate 101 (S102), the flow chart is ended, and the state before the plate making key 22 is pressed is returned (S10).
3).

If the original 101 is set (S10
1; Yes), a signal is sent to the solenoid 144 which is the drive source of the stopper 142 of the mounting device 46, and the stopper 14 is turned on.
2 is pulled in, slid, and moved to the position shown in FIG. 4 (S104). When the stamp member 120 is pushed down in this state, the two lift wires 140
End portions 140a of the respective abutting stoppers 142, and they cannot be pushed downward. The state of the stopper 142 corresponds to the prohibited state of the present invention, at which time the stamp member 120 is prohibited from moving to the mounting position of the present invention.

Next, the plate making operation is started. First, the number of lines for plate making is recognized from the input punched image data, and the number of lines is set in the register (S106). After that, the thermal head 114 is pressed against the set original plate 101 so that the punching operation is possible (S10).
7).

The plate making device 44 reads the data of the punching image corresponding to the number of plate making lines set in the register from the RAM of the storage device 45, and makes the plate 101 for one line by the thermal head 114. After one line of plate making, the driving roller 111 and the driven roller 112 send out the original plate 101 for one line (S108) and reduce the value of the number of plate making lines in the register by one (S1).
09). As a result, it is determined whether or not the number of plate-making lines stored in the register has become 0 (S110). If it is not 0, the process returns to S108 until it becomes 0, and the plate-making operation is repeated line by line.

When the number of plate making lines becomes 0 (S11
0; Yes), the thermal head 114 is separated from the original plate 101 (S112), and the punching operation is completed. After completion of the punching operation, the driving roller 111 and the driven roller 112 feed the original plate 101 (S113). Drive roller 11
1 is rotated a predetermined number of times to move the original plate 101 to an arrow A shown in FIG.
And from below to the stamp member 120 placed in the mounting device 46.

Finally, a signal is sent to the solenoid 144, and the solenoid 142 is driven to push out the stopper 142 to move it from the state shown in FIG. 4 to the state shown in FIG. 5 in the direction of arrow D (S114). Then, as shown in FIG. 5, the two groove portions 1 of the stopper 142 are
The end portions 140 a of the two lift wires 140 can pass through 43. Then, if the stamp member 120 is pushed in, it is possible to mount the original plate 101 that has been plate-made. FIG. 5 is a view showing a state in which the stamp member 120 is pushed down as indicated by an arrow C. The stamp member 12 at this time
The position of 0 corresponds to the mounting position of the present invention, and this stopper 1
The state of 42 corresponds to the mountable state of the present invention.

Here, the force for pushing down the two lift wires 140 is set to be smaller than the force required for the compression of the compression spring 125. Therefore, the pressing member 122 positioned inside the stamp member 120 does not project from the outer frame 124, the leaf spring 123 engages with the groove portion 109 of the original plate 101, and the attachment of the original plate 101 to the stamp member 120 is completed. After that, the stamp image is obtained by pulling up the stamp member 120 and imprinting it on a desired sheet.

With the above operation, the plate making and mounting operations are completed (S115). After that, the stamp device returns to the state before inputting the plate making key 22 and accepts a new process.

As is clear from the above description,
By using the original plate 101 and the stamping device of the present embodiment, the stamp member 120 cannot be pushed even if it is pushed down in the middle of punching and sending out the original plate 101, and the stamping member 120 can be pushed only after the punching and sending out. 12
0 and the original plate 101 are not attached, and the original plate 101 is not wasted and the inside of the stamp device is not polluted.

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.

For example, the restraining member does not fix the stamp member 120 as in this embodiment, but the stamp member 1
The movable area of 20 may be suppressed. For example, at least the original plate 101 is located above the surface on which the original plate 101 is transported.
It is also possible to provide a stopper 142 at a position spaced apart by a thickness corresponding to the above so as to maintain a distance that does not prevent the stamped plate 120 from being conveyed even when the stamp member 120 is pushed in during stamping.

[0044]

As is apparent from the above description,
In the stamp device of the present invention, the conveyance path of the stencil printing master plate is blocked, and a malfunction in mounting such as pressing the stencil printing master plate during transportation is prevented, and the stencil printing master plate is wasted due to a plate making defect, or ink The inside of the stamping device will not be contaminated by bleeding.
