BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic authentication and marking device suitable for use in a facsimile machine, a printer of a personal computer, a copying machine, and the like, and more particularly, a family register issued by a local government. In an automatic authentication stamping machine that automatically presses a seal against a certification statement for the purpose of authenticating a certified copy, an abstract, a seal seal, etc., especially ensure that the certification stamp does not hit the driven roller for stamping. The present invention relates to a stamping roller control method of an automatic authentication stamping machine which prevents the back side of a sheet from being stained.

[0002]

2. Description of the Related Art An automatic authentication stamping machine manufactured by NEC Corporation, which is commercially available as a model FZ-675, for example, using a conventional stamping roller control system, is caused by a paper conveyance jam. In order to correct the deviation of the position of the stamping roller, control has been performed to return the stamping roller to the standby position.

In this control, after the operator once opens the upper cover and eliminates the cause of the paper conveyance jam, the upper cover is closed by closing the upper cover, thereby confirming that the upper cover is fixed to the lower body. OPEN
Starts when the sensor detects, starts the stamping roller by connecting the stamping clutch and starts the paper transport motor, and the stamping roller standby position sensor detects that the stamping roller has returned to the standby position. At that time, the operation of disconnecting the sealing clutch and stopping the driving of the sealing roller was performed.

As another conventional example, for example, Japanese Utility Model Publication No. 61-4
No. 2847 can be cited.

The feature of the prior art described in Japanese Utility Model Publication No. 61-42847 is that a stamp plate for stamping a mark is formed in a roll shape, and this roll-like stamp roller is placed in a proper position of a sheet discharge roller. 1 is that the shaft is mounted via a one-turn clutch. Therefore, in the apparatus embodying the present invention, since the stamping roller is disposed coaxially with the sheet discharge roller, it is not necessary to newly provide a space for disposing the stamping mechanism, and the size and cost can be reduced. be able to. Further, in the mechanism of the present invention, since the mark for confirming the completion of the sheet feeding is imprinted just below the sheet discharging roller shaft, it is possible to accurately confirm whether the sheet discharging is completed.

[0006]

However, in the prior art described above, the driving of the stamping roller is performed in a state where the upper cover is fixed to the lower body and there is no paper between the stamping roller and the stamping driven roller. Is performed, the authentication mark located on the shaft of the stamping roller and the driven roller for stamping once come into direct contact with each other, so that the ink of the authentication mark is transferred to the driven roller for stamping, and the driven There is a drawback in that the back surface of the paper is stained with the ink attached to the rollers.

[0007] To explain the cause of such an idling of the stamping roller, the control is started from the time when the upper cover open sensor detects "open" and "close". In this case, since the deviation of the position of the stamping roller is not detected, it is not possible to determine the position of the stamping roller. Since it is not clear which direction is the conveyance direction or the opposite conveyance direction, a function is executed to rotate in either one direction and stop the stamping roller when the stamping roller standby position sensor detects the stamping roller.

In the structure of this conventional example, when the upper cover is closed, the stamping roller and the driven roller for stamping come into contact with each other, so that the blanking occurs.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional circumstances, and accordingly, an object of the present invention is to provide a new automatic authentication stamp machine capable of overcoming the above-mentioned disadvantages inherent in the prior art. An object of the present invention is to provide an impression roller control system.

[0010]

In order to achieve the above-mentioned object, the present invention relates to a method for controlling a stamping roller of an automatic authentication stamping machine. Control is performed to return the imprint roller to the standby position so as to correct the positional deviation. That is, when the operator opens the upper cover in order to eliminate the cause of the paper conveyance jam, it is determined that the stamping roller provided on the lower main body and the stamping driven roller provided on the upper cover are not in direct contact with each other. When the cover open sensor detects, the driving of the stamping roller is started by connecting the stamping clutch and activating the paper conveying motor, and the stamping roller standby position sensor detects that the stamping roller has returned to the standby position. Then, the connection of the stamping clutch is disconnected and the operation of stopping the driving of the stamping roller is executed.

[0011]

Next, a preferred embodiment of the present invention will be described in detail with reference to the drawings.

FIGS. 1 and 2 are views for explaining one embodiment of the present invention. FIG. 1 is a cross-sectional view showing a state in which the upper cover 17 is closed with the stamping roller 11 at the standby position. Is the certification mark 2 of the impression roller 11 with the upper cover 17 closed.
1 comes into contact with the stamping driven roller 12 via the paper 22,
FIG. 4 is a cross-sectional view illustrating a state in which a stamping operation is being performed on a sheet 22. FIG. 3 is a cross-sectional view showing a state in which the stamping roller 11 is being driven by opening the upper cover 17, and FIG. 4 is a schematic diagram showing a positional relationship among the stamping roller 11, the stamping clutch 16, and the authentication mark 21.

Referring to FIG. 1 to FIG.
Reference numeral 6 executes a function of driving / stopping the stamping roller 11 by connecting / disconnecting the rotating shaft 23 of the stamping roller 11. An authentication mark 21 is provided on the peripheral surface of the stamp roller 11 fixed to the rotating shaft 23. The stamping clutch 16 is connected to the paper transport motor 15 by a pulley 25 and a belt 24.

By connecting the stamping clutch 16 to the rotating shaft 23, the sheet conveying roller 13 and the stamping roller 11 are driven synchronously, and are conveyed by the sheet conveying roller 13 and the sheet conveying driven roller 14. The authentication mark 21 is pressed down on the sheet 22 by the stamping roller 11 and the stamping driven roller 12.

By disconnecting the stamping clutch 16 from the rotary shaft 23, only the paper transport is performed.

The automatic authentication machine according to the present invention controls the automatic authentication machine when a paper jam occurs.

Interruption of driving of the paper transport motor 15

Disconnection of the stamping clutch 16

Is executed.

With the above function, when the operator opens the upper cover 17 and removes the paper that caused the paper jam from the automatic authentication printer 10, it can be pulled out without any stress.

However, the above-mentioned "disconnection of the stamping clutch"
Is performed, the stamping roller 11 can be freely rotated by the addition from the outside, so that it rotates when the paper is pulled out. Since there is no mechanism for detecting the amount of rotation, the amount of returning the stamping roller 11 to the standby position is not known. Therefore, in the specification of the present application,
It expresses that "the position of the imprint roller is out of order."

The control of the position of the stamping roller 11 of the automatic authentication stamping machine 10 includes the control of returning the deviation of the position of the stamping roller 11 caused by the paper conveyance jam of the automatic authentication stamping machine 10 to the standby position, and the operation of the stamping roller. Rotate 11 one turn to form 2
And a control for stamping the authentication mark 21 on the second information.

In order to return the deviation of the position caused by the paper conveyance jam of the automatic authentication printer 10 to the standby position, the operator opens the upper cover 17, and the upper cover open (OPEN) sensor 20 detects this. The detection is started at the time of detection, and the driving of the stamping roller 11 is started by connecting the stamping clutch 16 to the stamping roller 11 and activating the sheet conveying motor 15. When the stamping roller standby position sensor 19 detects that the stamping roller 11 has returned to the standby position, the coupling of the stamping clutch 16 is disconnected, and the driving of the stamping roller 11 is stopped.

The control of stamping the authentication mark 21 on the sheet 22 by rotating the stamping roller 11 once is performed by the sheet conveying roller 13 and the sheet conveying driven roller 14. Is started when the sheet is conveyed to the position between the stamping roller 1 and the stamping roller 1.
1, the paper 22 is sandwiched from above and below by the stamping roller 11 and the stamping driven roller 12, and while the sheet 22 is sent out in the same direction as the transport direction, the ink of the authentication mark 21 on the axis of the stamping roller 11 is applied to the sheet 22. The imprint is performed on the sheet 22 by the transfer.

After the stamping is completed, the stamping roller 11 is driven as it is, and when the stamping roller standby position sensor 19 detects that the stamping roller 11 has returned to the standby position, the connection of the stamping clutch 16 to the stamping roller 11 is cut off. Then, the stamping roller 11 is stopped.

Further, according to the present invention, as shown in FIG. 1, when the upper cover 17 is fixed on the lower book pair 18 and the stamping roller 11 is at the standby position, the position between the stamping roller 11 and the stamping driven roller 12 is reduced. A structure is provided in which a sheet that is not to be stamped can pass while the stamping roller 11 is in the standby position.

[0027]

The present invention is constructed and operated as described above. According to the present invention, even if there is no special structure for avoiding contact between the stamping roller and the stamping driven roller,
Since the stamping roller can be returned to the standby position without causing the ink of the certification mark to adhere to the stamping driven roller, an effect of preventing the back surface of the sheet from being stained can be obtained.
