In recent years, for the purpose of reducing the discharge of dust, label paper without a mount, so-called linerless label, has been developed and spread. In a paper issuance (printer) device that prints such a linerless label, cuts it, and issues the label, since there is no mount on the paper, the glue on the back of the label is applied to the cutter blade of the cutter device that cuts the label. Therefore, it is necessary for the operator to open the cover body of the cutter device and clean the glue attached to the cutter blade directly with a cleaning pen or the like. At this time, the operator manually moves the cutter blade up and down so that it is easy to clean. When the cleaning is completed, the operator manually returns the cutter blade to the original position and closes the cover. However, it is not possible to return the initial position accurately only by manually moving the cutter blade, and the cover body may be closed with the cutter blade exposed at the cutting position due to forgetting to return.
When the paper issuing (printer) device is operated in this state, there is a problem that when the paper is transported to the cutting position, the leading edge of the paper comes into contact with the exposed cutter blade, and paper jam occurs in the cutter device. Could have occurred.

  And when the invention of the above prior art document detects an error of the cutter means, the cutter blade can be returned to the initial state, but when the cutter blade is moved manually, etc. No consideration was given to the return of the cutter blade, and the above problem could not be solved.

  The present invention has been made in view of these problems. In the cutter device, not only when an error state such as a paper jam occurs, but also in the movement of the cutter blade that occurs during normal operations such as cleaning of the cutter blade. It is another object of the present invention to provide a cutter device that can reliably and safely return the cutter blade to the initial position or the like, and a sheet issuing device including the cutter device.

  In order to achieve the above object, the present invention is a cutter device for cutting a strip-shaped sheet, and detects a movement or position of the cutter blade for cutting a strip-shaped sheet fed from a sheet roll, and the cutter blade. Detecting means, and when detecting that the cutter blade has been moved by the detecting means in the error state or maintenance state of the cutter device, the cutter blade when the error state or maintenance state of the cutter device is resolved Is returned to a predetermined position.

  According to the present invention, it is possible to reliably and safely return the cutter blade to the initial position after error handling such as a paper jam that is performed by opening and closing the cover body that covers the cutter device, and periodic cleaning of the cutter blade. Therefore, it is possible to prevent the paper from being conveyed while the cutter blade is in the cutting position, and it is possible to prevent the paper jam from occurring without the front end of the paper coming into contact with the cutter blade.

Then, cleaning is performed by wiping off the chips and glue on the labels attached to both surfaces of the fixed blade 22 and the movable blade 23 exposed with a cleaning tool such as a cotton swab soaked in alcohol or a cleaning pen. In the cutter device 2, the output gear 24 a of the stepping motor 24 and the transmission gear 25 a of the transmission means are used as the cutter blade manual operation means, but the movable blade 23 can be moved safely separately from the drive system of the movable blade 23. It is also possible to provide means for this.

(Drive control of paper issuing device)
Control of the sheet issuing apparatus according to the above embodiment of the present invention will be described with reference to FIGS.
A sheet issuing apparatus according to an embodiment of the present invention includes a control unit (CPU) 51 that controls driving of the entire automatic label printer including the sheet issuing apparatus, and a storage unit (ROM) that stores a program executed by the control unit 51. 52, a storage means (RAM) 53 for storing detection values of detection means provided in each apparatus of the automatic label printer, information to be printed on paper, and the like, and a status of each apparatus of the automatic label printer are displayed. A display operation unit C for inputting a command to the control unit, detection units such as a label detection unit 56 and a jam detection unit 57 for detecting the end of paper, input / output units such as an error lamp 13a and a power switch, Each driving unit such as the peeling roller driving unit 61 and the sticking device driving unit 32 is connected.
In this embodiment, in order to perform drive control of the cutter device 2, the cover body opening / closing detection means 15 that detects the opening / closing of the cover body (sticking device) 3 and the movable blade position that detects the vertical position of the movable blade 23. The detection means 26 and the stepping motor 24 are connected.
The control unit 51 drives the automatic sticker label printer by controlling the driving of each driving unit based on the input information from each detecting unit and the input / output unit according to the command of the program stored in the ROM 52. I have control.

In the normal driving state of the paper issuing apparatus according to the present embodiment, as shown in FIG. 6, the belt-like paper fed from the paper roll R is applied to the printer unit 13 in a state where an appropriate tension is applied by the pressing member 131. It is introduced, guided between the peeling rollers 134 and 135 via the guide rollers 132 and 133, and conveyed by the peeling rollers 134 and 135 driven by the peeling roller driving means 61. The belt-like sheets conveyed by the peeling rollers 134 and 135 are printed by a platen roller 136 and a thermal head 137 that rotate in synchronization with the rotation of the peeling rollers 134 and 135, and are arranged adjacent to the printer unit 13. Is sent to the cutter device 2.
The strip-shaped paper sent to the cutter device 2 creates a sheet-like label by moving the movable blade 23 up and down by the stepping motor 24 at the timing when the printed paper is conveyed a predetermined distance. doing.

(Cutter device return control)
In the normal driving state, when the control unit 51 receives any error signal, such as when the jam detection unit 57 detects a paper jam or the label detection unit 56 detects a paper out, the control is performed. The unit 51 drives and controls the stepping motor 24 so as to stop the movable blade 23 of the cutter device 2 at the initial position near the upper end position according to the instruction of the control program, and then the printer unit 13, the cutter device 2, and the pasting device 3. Is stopped and the error lamp 13a is turned on.
Similarly, when the user stops the operation by pressing the drive switch of the paper issuing device P at the end of the work or during maintenance such as cleaning the device, the control unit 51 similarly performs the cutter according to the instruction of the control program. After controlling the driving means to stop the movable blade 23 of the device 2 at the initial position near the upper end position, the drive of the printer unit 13, the cutter device 2, and the sticking device 3 is stopped.

Here, in order to eliminate an error such as a paper jam or out of paper that has occurred in the paper issuing device P, and for maintenance such as cleaning, the operator can remove the cover member 13b of the printer unit 13 or the cutter device 2 from the printer. Open the cover body (sticking device) 3 to expose various rollers such as the platen roller 136 and cutter blades (fixed blade 22 and movable blade 23), remove the paper, eliminate errors, and perform maintenance such as cleaning. After that, the cover member 13b and the cover body (sticking device) 3 are closed.
Among these, when an error occurs and the open state of the cover body 3 of the cutter device 2 is detected by the cover body opening / closing detection means 15, the movable blade 23 is moved by the movable blade position detection means 26. Is detected, the operator has removed the jammed paper etc. in the cutter device 2 and the error has been resolved, and the movable blade 23 of the cutter blade stopped without returning to the initial position or moved from the initial position. It is highly possible that
Also, when the operator presses the drive switch of the paper issuing device P at the end of the work or maintenance of the device and the paper issuing device P is stopped, the cover body opening / closing detection means 15 causes the cutter device 2 to When the open state of the cover body 3 is detected and the movable blade position detecting means 26 detects that the movable blade 23 is moving, it is considered that the operator has cleaned the cutter blade, etc. It is highly possible that the cutter blade has been moved.
Therefore, when the open state of the cover body 3 of the cutter device 2 is detected by the cover body opening / closing detection means 15 in the error state or maintenance state of the cutter apparatus as described above, the movable blade position detection means 26 detects the cutter blade. When the movement of the movable blade is detected, the cutter blade is returned to a predetermined position when the error state or the maintenance state of the cutter device 2 is resolved. The determination that the error state or the maintenance state of the cutter device 2 has been resolved is, for example, that the cover body 3 has been closed, or that the operator has been notified of the error by a button or the like. It can be determined that the error state or the maintenance state has been eliminated, but any other method may be used. Here, the movable blade of the cutter blade is returned to a predetermined position at the timing when the cover body open / close detection means 15 detects the closing of the cover body 3.

On the other hand, even if an error occurs, the cover body opening / closing detection means 15 does not detect the open state of the cover body 3 or the cover body 3 is open, but the movable blade position detection means 26 When it is detected that the movable blade 23 has not moved, for example, the operator cannot find a sheet in the cutter device 2 and opens the cover member 13b of the other printer unit 13 or the like to remove the sheet or simply replace the sheet. It is considered that the movable blade 23 of the cutter device 2 is stopped at the initial position.
Even when the paper switch P is stopped by pressing the drive switch, if the cover body opening / closing detection means 15 does not detect the open state of the cover body 3, maintenance of the printer unit 13 or the like is performed. There is a high possibility that the cutter blade of the cutter device 2 has stopped at the initial position.

Therefore, in the paper issuing device according to the embodiment of the present invention, when an error or the like is released or when the maintenance work is completed, for example, the error processing and the maintenance are finished and the cover body 3 of the cutter device 2 is closed. When it is detected that the cutter blade is moving by the movable blade position detecting means 26, the cutter blade is controlled to return.
On the other hand, even if it is detected by the cover body opening / closing detection means 15 that the cover body 3 is closed, if the movable blade position detection means 26 does not detect that the movable blade 23 is moving, The return control of the movable blade 23 is prohibited, and the stepping motor 24 is not driven.

As described above, in the embodiment of the present invention, when it is detected that the cutter blade of the cutter device 2 is moved by an external force other than the driving force of the stepping motor 24, the cutter device shifts to a normal use state. Accordingly, the driving of the cutter blade is automatically returned to the initial state, so that the leading edge of the paper can be prevented from coming into contact with the cutter blade when the paper is issued, and the occurrence of paper jam can be prevented.
Further, since it is set so that the return operation is not performed when only the opening / closing operation of the cover member of the cutter device is detected, it is possible to promptly shift to the sheet issuing operation without performing an unnecessary return operation.
Furthermore, the return control of the cutter device is safe at the timing when the cover body of the cutter device is closed, so that the movable blade is not exposed when the movable blade is driven.

  The printer apparatus of the present invention is not limited to the above embodiment, and any printing method may be used. Further, the apparatus in which the paper issuing device is arranged is not limited to the automatic label printer, but may be a POS register or a ticket issuing machine.
