Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auto-cutter device which is used by being incorporated in various devices such as a small-sized printer for issuing documents, for example, in which a blade installed reciprocally is in a locked state. In this case, the present invention relates to a device configured to restore this by a software means.

[0002]

2. Description of the Related Art For example, a small printer for issuing forms, etc. is equipped with various types of auto-cutter devices so that a printer body automatically cuts and ejects a sheet on which a predetermined print is made. There is. At that time, the blade provided so as to be able to reciprocate may be in a locked state. That is, the sheet is caught in the blade, and further forward movement of the blade is restricted. In such a case, the blade is returned in the backward direction to release the locked state, and the work of removing the jammed paper is performed.

As a means for releasing the locked state,
There are the following: First of all, not only the equipment case of the small printer, but also the cutter cover that covers the entire auto-cutter device is removed to expose the drive unit, and in that state, manually operate the drive unit to move the blade back and forth. It is to move. Further, as a device for releasing the locked state without removing the cutter cover, there is, for example, a device disclosed in Japanese Utility Model Laid-Open No. 4-13361. This is a part of the train wheel mechanism of the drive unit (1 in the gear group).
Part of each gear) is projected and arranged from the cutter cover, and the projected and arranged part is manually operated to move the blade in the backward direction.

[0004]

According to the above conventional structure, there are the following problems. That is, in any of the conventional cases, there is a problem that the operator must manually operate the mechanism section to release the locked state, which complicates the work. Especially when you cannot do it at the operator level (for example,
The cashier) would stop, which would be a major obstacle to sales, and it was extremely troublesome to call a professional service person. There is also a problem that the blade is damaged when the operator tries to remove the paper by force.

The present invention has been made on the basis of such a point, and an object of the present invention is to return a blade in a locked state by a soft means without requiring any complicated returning work. It is to provide an automatic cutter device capable of

[0006]

In order to achieve the above object, an automatic cutter device according to the present invention comprises a blade reciprocally arranged, a drive motor for outputting power for reciprocating the blade, and the drive motor. A drive mechanism that transmits the rotational force from the blade to the blade to reciprocate the blade, and detects that the blade is locked and further movement is restricted during the cutting operation by the forward rotation of the drive motor. Detection means,
And a control unit for inputting a signal from the detection unit to reversely rotate the drive motor to move the blade in the opposite direction to return the blade.
At that time, it is conceivable that the error lamp is turned on when the blade is locked during the cutting operation, and the blade returning process is performed by operating the switch based on the lighting of the error lamp. It is also conceivable that when the blade is locked during the cutting operation, the error lamp is turned on and the blade is returned.

[0007]

First, in the normal cutting operation, the blade is moved in the forward direction via the drive mechanism by the forward rotation of the drive motor to cut the sheet. When the drive motor further rotates in the forward direction, the blade that has finished cutting moves in the backward direction via the drive mechanism and returns to the initial position. This is 1
The disconnection operation of times ends. At this time, the blade may be in a locked state in which further movement of the blade is restricted due to paper jam or the like. This is detected by the detection means, and based on this, the control means functions to reversely rotate the drive motor to move the blade in the opposite direction to restore the blade. After that, the normal condition is restored by removing the jammed paper. The control means may be configured to restore, for example, when an error lamp is turned on when the lock state is set, and then the switch is operated to perform the restoration process, or when the lock state is set. It is conceivable that the error lamp is turned on and the recovery process is performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS. First, the automatic cutter device according to the present embodiment has a configuration as shown in FIGS. First, there is a cutter cover 1 as shown in FIG.
Below the cutter cover 1, a cutter frame 3 as shown in FIG. 1 is installed. The cutter cover 1 shown in FIG. 2 is integrated with the cutter frame 3 shown in FIG. A side wall 4 is provided upright on three sides of the cutter frame 3. The cutter frame 3 is provided with a sheet introduction port 5 into which a sheet (not shown) that has been subjected to predetermined printing by a printer body (not shown) is introduced, and the sheet that has been cut is discharged to the cutter cover 1. A paper discharge port 7 is formed. The paper discharge port 7 has a simple rectangular shape as is clear from FIG.

A fixed blade 9 is fixed on the cutter frame 3 side and above the sheet introduction port 5 in FIG. on the other hand,
A movable blade 11 is arranged below the sheet introduction port 5 in FIG. 1, and the movable blade 11 is attached by a drive means 13 so as to be reciprocally movable in the vertical direction in FIG. The structure of the driving means 13 will be described below. First, the drive motor 15 is installed, and the worm gear 17 is fixed to the rotary shaft of the drive motor 15. A worm wheel 19 is arranged, and the worm wheel 19 meshes with the worm gear 17. The drive motor 15, worm gear 17, and worm wheel 19 are
It is attached to the cutter cover 1 side, and
Is shown with a virtual line. Further, the cutter cover 1 is notched in the mounting portion of the drive motor 15 to form an opening 20.

On the other hand, a swing lever 21 is mounted on the cutter frame 3 so as to swing around a fulcrum 23. A cam groove 25 is formed on the right side portion of the swing lever 21 in FIG. 1, and the cam groove 25 is provided so as to project from the lower end surface of the worm wheel 19 as shown in FIGS. The cam pin 27 is movably engaged.
Further, another groove 29 is formed at the center of the swing lever 21. Further, below the swing lever 21, the pressing plate 3
1, a slider 35 and a stop plate 37 are arranged, and the pressing plate 31, the slider 35, and the stop plate 37 are screw members 33,
It is integrated by 34.

The mounting structure of the pressing plate 31, the slider 35, the stopper plate 37, and the movable blade 11 already described will be described in more detail. First, at the center of the cutter frame 3, as shown in FIGS.
A rectangular slide groove 36 extending in the reciprocating direction is formed. The slider 35 is slidably fitted in the slide groove 36. Also, FIG.
As shown in, the movable blade 11 is placed on the slider 35 via the sliding sheet 38, and the pressing plate 31 is further placed thereon. On the other hand, the stopper plate 37 is installed below the slider 35 via another sliding sheet 40. In that state, the screw member 33 already described,
It is screwed and coupled by 34. As a result, the pressing plate 31, the movable blade 11, the sliding sheet 38, the slider 35, the sliding sheet 40, and the stopper plate 37 are stacked and fixed in this order from the top. The pressing plate 31 and the movable blade 11 are stacked in a state as shown in FIG. .. The stop plate 37, the sliding sheet 40, and the slider 35 are stacked in the state shown in the back view of FIG. The upper portion of the screw member 33 is projected upward and is movably engaged with the groove 29 of the swing lever 21. Further, as shown in FIG. 4, a recess 42 is formed at the tip of the slider 35, and the pressing plate 31 at that portion is crimped (the crimped portion is indicated by reference numeral 44).

According to the above construction, when the drive motor 15 rotates, the worm wheel 19 rotates counterclockwise in FIG. 1 (direction indicated by arrow a in the figure) via the worm gear 17. When the worm wheel 19 rotates, the swing lever 21 swings in the forward direction (counterclockwise direction in FIG. 1, indicated by arrow b in the figure). Thereby,
The pressing plate 31 and the movable blade 1 through the upper portion of the screw member 33.
1, sliding sheet 38, slider 35, sliding sheet 4
0, the stop plate 37 moves linearly along the slide groove 36 in the forward direction. That is, the rotational movement of the drive motor 19 is converted into the linear movement along the slide groove 36. As a result, the movable blade 11 and the fixed blade 9 perform a shearing operation to cut the sheet. Further, when the worm wheel 19 makes a half turn from the state shown in FIG. 1 and makes a further half turn, the swing lever 21 swings in the backward movement direction (clockwise direction in FIG. 1), which causes the pressing plate. 31, movable blade 11, sliding sheet 38, slider 3
5, the sliding sheet 40, and the stop plate 37 also linearly move in the backward movement direction along the slide groove 36 and return to the original position. This completes one cutting operation.

Next, the structure of the control means 41 for controlling the above-mentioned automatic cutter device will be described with reference to FIG.
The control means 41 includes a CPU 43, a ROM 45, a RAM 4
7, an I / O 49, a driver 51, an online switch 53 as a switch, an error lamp 55, and a driver 57. In addition to the drive motor 15 already described, the auto cutter device is provided with a sensor 59 as a detecting means. The automatic cutter device is incorporated in a small printer, and the printer mechanism portion of the small printer is indicated by reference numeral 61. Also, CPU4
3 is provided with a timer 63. The control means 4
1 functions to return the movable blade 11 when it is in a locked state. That is, when the movable blade 11 is locked, this is detected by the signal from the sensor 59. The control means 41 is a sensor 59
The error lamp 55 is turned on to display an error on the basis of the signal from, and the drive motor 15 is rotated in the reverse direction to restore the movable blade 11 in the locked state.

The sensor 59 is constructed as shown in FIG. That is, there is a rotating body 65 having the worm wheel 19, and the rotating body 65 is formed with a notch 67 at a predetermined angle. On the other hand, a switch 69 is installed at the outer peripheral position of the rotating body 65. When the switch 69 and the rotating body 65 are in the positional relationship shown in FIG. 7, the switch 69 is in the off state, and the sensor 59 is also in the off state. On the contrary, when the worm wheel 19 and the rotating body 65 rotate forward (rotate in the direction indicated by the arrow in FIG. 7) to perform the cutting operation, the switch 69 causes the outer periphery of the rotating body 65 (the cutout 67).
(The outer peripheral portion on the left side in the figure), the switch 69 and thus the sensor 59 are turned on. Then, while the disconnection operation is being performed, the switch 69, and thus the sensor 59, continues to be in the ON state, and when the rotating body 65 makes one rotation and returns to the state shown in FIG. 59
Is turned off. In the case of this embodiment, the sensor 59
On. The locked state of the movable blade 11 is detected by monitoring the off state.

The operation will be described based on the above configuration. First, the initialization process of the automatic cutter will be described with reference to the flowchart of FIG. When the power source of the small printer is turned on (sequence S1), it is determined whether the reset pulse is "HIGH". This is a determination as to whether or not the sensor 59 has returned to the initial state. In the normal case, the sensor 59 has returned to the initial state as shown in FIG. 7, and the switch 69 and thus the sensor 59 are in the off state. And the reset pulse is in the "HIGH" state. If the reset pulse is "HIGH", the process ends. On the other hand, when the reset pulse is not "HIGH", the "return process 1" (sequence S3) is performed, and then the process ends.
This "recovery process 1" will be described in detail later.

Next, the cutting operation of the automatic cutter will be described with reference to the flowchart of FIG. First, it is determined whether or not the printer mechanism unit 61 is stopped (sequence S4). That is, in the case of this embodiment, when the paper is cut by the automatic cutter device, the printing operation by the printer mechanism unit 61 is stopped. .. When the printer mechanism unit 61 is not stopped, the determination of the sequence S4 is repeated. When the printer mechanism unit 61 is stopped, the timer 63 is set to 400 ms (sequence S5) and started (sequence S6). 4 above
00 ms is set as the time required for the sensor 59 to switch from the initial state (off state) to the on state, and takes into consideration the cutout portion 67 shown in FIG. 7. Then, the drive motor 15 starts normal rotation (sequence S7). The cutting operation is started by the normal rotation of the drive motor 15. That is, in FIG. 1, the worm wheel 19 rotates counterclockwise in the figure, and the swing lever 21 starts swinging in the forward direction accordingly. Thereby, the movable blade 11 starts moving in the forward direction.

Next, it is determined whether or not the timer 63 has timed out (whether or not 400 ms has elapsed) (sequence S8). That is, it is a determination as to whether or not the sensor 59 is normally turned on within the set time of 400 ms. When the sensor 59 does not turn on within the time of 400 ms, that is, when the timer 63 times out, the process returns to the "return process 2" (sequence S9) and returns to the sequence S5 again. In such a state, not only the sensor 59 itself may fail, but the movement of the movable blade 11 in the forward movement direction may be restricted in the initial state for some reason.
For some reason, it is conceivable that a plurality of sheets are jammed and the movable blade 11 is locked at the initial stage. The contents of the "recovery process 2" will be described in detail later. On the other hand, when the timer 63 has not timed up, it is determined whether or not the reset pulse falls (sequence S1).
0). That is, when the sensor 59 is turned on, the reset pulse falls. If the reset pulse has not fallen, the process returns to sequence S8 and the above determination is repeated. On the other hand, when the reset pulse is falling, the timer 63 is set to 12
The timer 63 is set to 00 ms (sequence S11) and the timer 63 is started (sequence S12). 120 above
0 ms considers the time required to complete one cutting operation. That is, it is set as the time required for the movable blade 11 to move forward to cut the sheet with the fixed blade 9 and then to move back and return to the initial position.

Next, it is determined whether or not the timer 63 has timed out (sequence S13). That is, it is determined whether or not one cutting operation is normally completed within the set time of 1200 ms. When one cutting operation is not normally completed within the set time of 1200 ms, that is, when the timer 63 has timed up, the process proceeds to the restoration process 1 (sequence S14) and the sequence S5. Return to.
In such a case, the movable blade 11 may be locked in the forward movement stage. That is,
If the sheet is not normally cut and the sheet is still sandwiched between the movable blade 11 and the fixed blade 9,
It is in a state where the further movement of the car is regulated.
Apart from that, it is expected that the movable blade 11 will be locked in the backward movement stage. This is because after the cutting of the paper is completed, the paper is not ejected smoothly and jams,
As a result, the backward movement of the movable blade 11 is restricted. If the timer 63 has not timed out, it is determined whether or not the reset pulse has risen (sequence S15). That is, when one cutting operation is normally completed, the sensor 59 has returned from the on state to the initial off state, and the reset pulse rises. If the reset pulse has not risen, the process returns to sequence S13 and the above determination is repeated. On the other hand, when the reset pulse has risen, the drive motor 15 is stopped (sequence S16), and the process ends. with this,
This means that one cutting operation has been normally performed.

Next, referring to the flowchart of FIG. 10, the "return processing 1" and "return processing 2" already described will be described. In addition, the above "recovery process 1", "recovery process 2"
Will be briefly explained. First, in the "recovery process 1", the sensor 59 is normally turned on within the set time of 400 ms from the initial state, but the movable blade 11 is in the locked state on the assumption of the subsequent cutting operation. In such a case, the drive motor 15 is reversed to move the movable blade 11
Means a process for restoring the normal state. On the other hand, the "recovery process 2" means that the sensor 59 is not normally turned on within the set time of 400 ms from the initial state, that is, the movable blade 11 is locked at the initial stage. In the case such as, the drive motor 15 is reversely rotated to return the movable blade 11 to a normal initial state.

First, in the case of "return processing 1", first,
Error processing is performed (sequence S17). This error processing is as shown in FIG. That is, the drive motor 15 is stopped (sequence S18),
At the same time, the error lamp 55 is turned on (sequence S19). Next, it is determined whether or not the online switch 53 has been pressed (sequence S20).
If the online switch 53 is not pressed, the above determination is repeated. On the other hand, when the online switch 53 is pressed, the following steps are performed. That is, returning to FIG. 10, the timer 63 is set to a time of 1200 ms (sequence S18), and the timer 63 is started (sequence S19). At the same time, the drive motor 15 starts reverse rotation (sequence S20). As a result, the movable blade 11 returns from the locked state in the backward movement direction. Although the set time is 1200 ms, this is also assumed when the movable blade 11 completes the forward movement and shifts to the backward movement to be in the locked state immediately before the end of one cutting operation. Therefore, the set time is 1200 ms corresponding to the time required for one cutting operation to end normally.

Next, it is judged whether or not the timer 63 has timed out (sequence S21). this is,
This is a determination as to whether or not the movable blade 11 has moved in the backward direction and returned to the initial state within the set time of 1200 ms, and the sensor 59 is in the off state. 120 above
When the initial state as described above is not restored within the set time of 0 ms, that is, when the timer 63 times out, the process returns to the sequence S17 and the above steps are repeated. On the other hand, when the timer 63 has not timed up, it is determined whether or not the reset pulse has risen (sequence S22). That is, it is determined whether the sensor 59 is on or off. If the reset pulse has not risen, the process returns to the sequence S21 and the determination is repeated. If the reset pulse is rising (the sensor 59 is turned off), the timer 63 is set to 40
Set 0ms (Sequence S23), timer 6
3 is started (sequence S24). 400m above
Although the set time is s, this is because the movable blade 11 moves in the backward movement direction and the sensor 59 shifts from the ON state to the OFF state. The purpose is to move the drive motor 15 back to the initial state, and to further reverse the drive motor 15 within the range of the notch 67 shown in FIG. 7.

Next, it is determined whether or not the timer 63 has timed out (sequence S25). At this point, the drive motor 15 is still rotating in the reverse direction as described above. When the timer 63 has timed out, the process proceeds to the error processing of sequence S26. On the other hand, if the timer 63 has not timed up,
In sequence S27, it is determined whether or not the reset pulse has fallen. This is the drive motor 15
Is reversed to turn the sensor 59 from an on state to an off state, and further to be reversed to determine whether the sensor 59 is turned on. That is, in FIG. 7, the switch 69 is turned on by the outer peripheral portion on the left side of the cutout portion 67 of the rotating body 65 in the drawing after passing through the cutout portion 67. If the reset pulse has not fallen, the process returns to the sequence S25 and the above determination is continued. On the other hand, when the reset pulse has fallen, the process proceeds to sequence S28 and the drive motor 15 is stopped.

After stopping the drive motor 15, the timer 63 is set to 400 ms (sequence S29),
The timer 63 is started (sequence S30).
Then, the drive motor 15 is normally rotated (sequence S3
1). Next, it is determined whether or not the timer 63 has timed out (sequence S32). If the timer 63 has timed out, the process proceeds to error processing (sequence S33), and then returns to sequence S29. On the other hand, when the timer 63 has not timed up, it is determined whether or not the reset pulse has risen (the sensor 59 is turned on / off) (sequence S34). That is, due to the reverse rotation of the drive motor 15, the sensor 59 is in the ON state on the opposite side from the OFF state (a position slightly past the initial state). It is to return to the state. If the reset pulse has not risen, the process returns to sequence S32. On the other hand, when the reset pulse rises (the sensor 59 is turned off), the drive motor 15 is stopped (sequence S35), and the error lamp 55 is turned off (sequence S36). This means that the device has returned to the normal initial state. The operator confirms that the error lamp 55 is off,
Remove the jammed paper. Then, it is determined whether or not the online switch 53 has been pressed (sequence S37), and if it has been pressed, the process ends.
If it is not pressed, the determination as to whether or not the online switch 53 is pressed is repeated. The above is the processing of “recovery processing 1”.

Next, the "recovery process 2" will be described.
First, the error processing of sequence S26 is performed. This error processing is performed by the drive motor 1 as already described.
5, the error lamp 55 is turned on, and the online switch 53 is pressed. By pressing the online switch 53, a time of 400 ms is set in the timer 63 (sequence S39), and the timer 63 is started (sequence S41). Then, the drive motor 15 is rotated in the reverse direction (sequence S43). After that, the sequence proceeds to the sequence S25 described in the "return process 1" and the same process as that already described is performed.

Although the set time is 400 ms, in the case of "recovery process 1", the set time is 1200 ms as described in sequence S18. On the other hand, 400 ms in the case of "recovery process 2" means that in the case of "recovery process 2", the disconnection operation is started and the initial stage (the state in which the sensor 59 is turned off is changed to the on state). This is because the lock state is a problem.

According to this embodiment, the following effects can be obtained. First, when the movable blade 11 is locked during the cutting operation, the movable blade 11 can be returned to the initial state by a software means without performing a complicated return work using a jig or the like. I can do it. That is, the above-described processing is automatically performed and the movable blade 11 is returned to the initial state only by pressing the online switch 53 while seeing the lighting of the error lamp 55. Then, after confirming that the movable blade 11 has returned to the initial state and the error lamp 55 has been turned off, the jammed paper may be removed. When the movable blade 11 is in the locked state, the paper is forcibly removed. Therefore, the movable blade 11 will not be inadvertently damaged. That is, it is not necessary to remove the paper while the error lamp 55 is on, and the operator should be alerted to that effect.

Further, the contents of the locked state of the movable blade 11 are classified into two types, and different return processes, that is,
Since the "returning process 1" or the "returning process 2" is performed, it is possible to provide an appropriate returning process suitable for the content of the locked state of the movable blade 11. Further, even when the printer is restarted after the "recovery process 1" or the "recovery process 2" has been performed, the power of the printer remains on, so that the data once input is not lost.
Subsequent work is also easy.

Next, a second embodiment will be described with reference to FIG. In the case of the first embodiment, when the movable blade 11 is in the locked state, the error lamp 55 is turned on, and the operator confirms it and presses the online switch 53 to perform the "return processing 1" or the "return processing". 2 ”was performed. On the other hand, in the case of the second embodiment, the "return process 1" or "return process 2" is automatically performed without the need to press the online switch 53.

First, in the case of "return processing 1", the drive motor 15 is stopped (sequence S45). Next, the error lamp 55 is turned on (sequence S4).
7). Next, as in the case of the first embodiment, the time of 1200 ms is set in the timer 63 (sequence S18 '). Hereinafter, the same processing as in FIG.
A sequence number of 0 is attached with "'" and its description is omitted. The difference from the first embodiment is that, first, when the timer 63 times out in sequence S21 ', error processing is performed (sequence S4).
9) After that, the process proceeds to sequence S18 '. Further, after the drive motor 15 is stopped in the sequence S35 ', it is first confirmed whether or not the online switch 53 is pressed (sequence S51).
When the is pressed, the error lamp 55 is turned off and the process ends. When the online switch 53 is not pressed, it is repeatedly confirmed. Further, the removal work of the jammed paper is carried out after confirming that the error lamp 55 is turned off.

Next, the case of "recovery process 2" will be described. Also in this case, first, the drive motor 15 is stopped (sequence S55), and the error lamp 55 is turned on (sequence S57). After that, the same processing as in the case of the first embodiment is performed, and the sequence number in FIG. Note that the difference from the case of the first embodiment is that when the timer 63 times out in sequence S25 ′, the process proceeds to error processing (sequence S59), and then sequence S
This is the point to return to 39 '. Further, the difference at the final stage of the processing is as described in the above "return processing 1".

Therefore, even in the case of this embodiment, the same effect as in the case of the first embodiment can be obtained, and even if the operator does not press the online switch 53, the "return processing" is automatically performed. Since "1" or "recovery process 2" is performed, the automation of the system is further promoted. Incidentally, when the error lamp 55 that has been turned on is finally turned off, it is necessary to press the online switch 53 as described above.
This is rather preferable for removing the jammed paper after confirming that the movable blade 11 in the locked state has returned to the initial state.

The present invention is not limited to the above embodiments. First, the configuration of the sensor 59, that is, the detection means is not limited to that shown in each of the above embodiments. For example, it may be detected by an optical switch. Also, the time set in the timer 63 may be appropriately selected and set.
It is not limited to 200 ms. Further, although the online switch is used as the switch in each of the above embodiments, a dedicated switch may be provided separately. or,
In each of the above-mentioned embodiments, an automatic cutter device of a type including a movable blade and a fixed blade has been described as an example, but the type of the automatic cutter device is not limited thereto, and various types such as a type including only a movable blade. It can be applied to any type of auto cutter device. Furthermore, in each of the above-described embodiments, the automatic cutter device incorporated in the small printer has been described as an example, but the device to be incorporated is not specified.

[0033]

As described in detail above, according to the automatic cutter device of the present invention, the state of the drive mechanism is constantly monitored by the detecting means, and when the blade is in the locked state, this is detected, and based on this Since the control means reverses the drive motor to restore the blade, it is possible to restore the blade to a normal state by a software means without performing complicated restoration work using a jig or the like. It can be used and is greatly improved in use.
