Abstract

PURPOSE:To detect wrong detection of marking while a ticket issuing machine is operating, and increase the service life of a mark detection means. CONSTITUTION:When a ticket issuing command is given, the forward rotation of a pulse motor 46 is driven by a controller 50, and roll paper 14 is fed in a direction of F1 through an epicyclic gear mechanism 44 and a feed roller 30. A mark on the roll paper approaches a mark detection sensor 48, the controller 50 generates a mark detecting signal effective condition, and the mark detection sensor 48 is turned off. Reversing is driven by the controller 50, and a cutter 32 is driven through the epicyclic gear mechanism 44, a cutter driving gear 42 and a rack 32, thus cutting the roll paper. It is possible to prevent the mark from being detected by mistake through the effective/ineffective control of the signals and lengthen service life by ON/OFF control of a sensor.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ticket issuing machine for issuing tickets from roll paper on which a large number of tickets are printed.

[0002]

2. Description of the Related Art In a ticket issuing machine using roll paper on which a large number of tickets are printed in advance at predetermined intervals, a mark indicating the division of each ticket is attached, and the ticket is cut using this mark. . This will be described below with reference to FIGS. 8 and 9. First, it is assumed that the cutter 100, the optical sensor 102 for detecting a mark, and the roll paper 104 are in the positional relationship as shown in FIG. When there is a ticket issuing instruction based on the insertion of coins (FIG. 9, step SA), the optical sensor 102 is turned on to enable the mark detection, and the roll paper feed is started based on the ticket issuing instruction signal (step SB), FIG. 8
The roll paper 104 is fed as shown in FIG.

When the mark M passes through the optical sensor 102 and a mark indicating the division of the ticket is detected (step S
(Y in C), and then the roll paper is fed by a predetermined length (FIG. 8C). As a result, one ticket is sent first from the cutter 100. At this point, the roll paper feeding is stopped (step SD). Then, as shown in FIG. 8D, the fed roll paper is cut to issue a ticket TK (step SE), and the optical sensor 102 is turned off.

[0004]

However, the above conventional techniques have the following disadvantages. (1) When the distance between the cutter 100 and the optical sensor 102 is an integral multiple of the mark pitch LM (see FIG. 8) or slightly long, the optical sensor 102 may erroneously detect the mark M. In the case of FIG. 8A, the distance between the cutter 100 and the optical sensor 102 is 4L with respect to the mark pitch LM.
It is M + Δ, which is longer by Δ. Therefore, the length of feeding the roll paper after the optical sensor 102 detects the mark M is Δ, which is a short distance.

Then, as shown in FIG. 3D, when the roll paper 104 is cut, the optical sensor 102 is cut.
Is at the position Δ from the mark M. At this point, if a ticket issuing instruction is issued again, the operation of each step shown in FIG. 9 is performed. In this case, when the mark detection area of the optical sensor 102 is equal to or wider than Δ, the already detected mark remains within the sensor detection area. Then, the mark M already detected
Is again detected by the optical sensor 102, the result is “Y” in step SC immediately after the start of the operation, and the cutter 100 operates in the state shown in FIG. 8 (E). In such a case, one ticket will not be issued.

(2) Further, in the above-mentioned prior art, since the light emitting portion of the optical sensor 102 continues to emit light after the ticket issuing machine starts receiving the ticket issuing instruction and finishes issuing the ticket, the life of the light emitting portion is extended. There is also the inconvenience of becoming shorter. The present invention focuses on these points, and a first object thereof is to prevent an erroneous detection by the mark detecting means and to issue one ticket satisfactorily. A second object is to extend the life of the light emitting means when the light emitting means is used as the mark detecting means.

[0007]

In order to achieve the above object, the present invention provides a mark detecting means when the roll paper is fed by the roll paper feeding means and the mark seems to approach the mark detecting means. Is provided, and signal control means for invalidating the output of the mark detecting means when the mark detecting means detects the mark is provided. Until the mark detection means seems to have approached the mark,
Since the output is not treated as valid, the erroneous detection of the mark is well prevented.

Further, in response to the valid / invalid control of the output of the mark detecting means, the control of the sensor operation start / stop,
For example, the presence / absence of energization of a light emitting diode, which is a light emitter of an optical sensor, is controlled. Therefore, the time for energizing the light emitter is shortened, and the life can be extended.

The main aspects of the present invention are as follows. (1) The roll paper control means is a drive motor means; when the drive motor means rotates to one side, the drive force of the motor means is transmitted to the roll paper feed means, and when the drive motor means rotates to the other, the motor is driven. Power transmission means for transmitting the driving force of the means to the roll paper cutting means; first motor control means for rotating the motor means to one side when a ticket issuing instruction is issued; mark during roll paper feeding by the roll paper feeding means Second motor control means for rotating the motor means to the other when the mark is detected by the detection means;

(2) The roll paper control means is a driving motor means; when the driving motor means rotates in one direction,
Power transmission means for transmitting the driving force of the motor means to the roll paper feeding means and for transmitting the driving force of the motor means to the roll paper cutting means when rotating to the other; the motor means to one side when a ticket issuing instruction is issued. First motor control means for rotating; when a mark is detected by the mark detection means while the roll paper is being fed by the roll paper feed means, the roll paper feed means sets the amount of roll paper necessary for cutting one ticket. Second motor control means for feeding and then rotating the motor means to the other.

(3) The roll paper control means further determines an abnormality when the mark is not detected by the mark detection means even when the roll paper feeding means feeds the roll paper of a mark detectable amount; It is characterized by having.

[0012]

Embodiments of the ticket issuing machine according to the present invention will be described in detail below with reference to the accompanying drawings. <Embodiment 1> FIG. 1 shows a configuration of the embodiment apparatus viewed from the side. In the figure, the roll paper shaft 10 is attached to a frame (not shown) located forward and backward in the plane of the drawing.
Is pivotally supported. The roll paper shaft 10 is provided with a roll 12 around which a paper on which a large number of tickets are printed in advance at predetermined intervals is wound. Guides 16, 18 for guiding and feeding the roll paper 14, a pair of paper pressing rollers 20, 22, guides 24, 26, a paper pressing roller 28, and a paper feeding roller 30 are provided on the roll paper pulling side of the roll 12. They are provided in order.

A cutter 32 for cutting the roll paper 14 is provided on the exit side of the roll paper 14. The cutter 32 includes a fixed blade 34, a movable blade 36, and a return spring 38 for returning the movable blade 36 to a predetermined position. A rack 40 is provided on the movable blade 36, and a cutter driving gear 42 is meshed with the rack 40.

A pulse motor (stepping motor) is applied to the paper feed roller 30 by a planetary gear mechanism 44.
The driving force is transmitted when 46 rotates in the forward direction, and the driving force is released when 46 rotates in the reverse direction.
Further, the planetary gear mechanism 4 is attached to the cutter drive gear 42.
4, the driving force is transmitted when the pulse motor 46 rotates in the reverse direction, and the driving force is released when the pulse motor 46 rotates in the normal direction.

FIG. 2 shows how these operations are performed. In the figure, only the pitch circle of the gear is shown. First, as shown in FIG.
When A rotates in the direction of arrow F10, the gear 44A of the planetary gear mechanism 44 rotates counterclockwise. Gear 44A and Gear 4
Since it is integrated with 4B, the gear 44B also rotates counterclockwise. Then, the gears 44C and 44D, which are in a planetary gear relationship with the sun gear gear 44B, rotate and move counterclockwise as a whole, the gear 44D moves away from the cutter driving gear 42, and the gear 44C moves. It comes to mesh with the feed gear 30A. Therefore, the driving force of the gear 44B is transmitted to the feed gear 30A via the gear 44C, the feed roller 30 rotates, and the roll paper 14 is fed in the direction of arrow F1.

Next, as shown in FIG. 3B, when the pulse motor 46 rotates in the direction of arrow F12, the gears 44A and 44B of the planetary gear mechanism 44 rotate clockwise. Then, the gears 44C and 44D rotate clockwise as a whole, the gear 44C separates from the feed gear 30A, and the gear 44D meshes with the cutter driving gear 42. Therefore, the driving force of the gear 44B is transmitted to the cutter driving gear 42 and the rack 40 via the gear 44D, the moving blade 36 of the cutter 32 moves in the arrow F2 direction, and the roll paper 14 is cut. As described above, the roll paper 14 is fed by the normal rotation of the pulse motor 46,
The roll paper 14 is cut by reversing.

Next, returning to FIG. 1, the guides 24, 26
Between the paper pressing roller 28 and the paper feeding roller 30 toward the roll paper 14 a light emitting device (for example, a light emitting diode).
And a light receiver (for example, a photo IC or a phototransistor) is provided as a reflection type optical sensor 48. Marks are provided on the roll paper 14 at intervals of one ticket, and this is detected by the optical sensor 48.

The pulse motor 46 and the optical sensor 48 are connected to the control device 50. The control device 50 is configured as shown in FIG. 3, and includes a forward rotation pulse output unit 52, a reverse rotation pulse output unit 54, a sensor operation control unit 56, an abnormality determination unit 58, and a signal control unit 60.

Of these, the forward rotation pulse output section 52 is for supplying the forward rotation driving pulse to the pulse motor 46, and the reverse rotation pulse output section 54 is for supplying the reverse rotation driving pulse. belongs to. The sensor operation control unit 56 is for controlling the operation of the optical sensor 48 in accordance with the output state of the forward rotation pulse and the sensor detection signal.
The abnormality determination unit 58 is for determining whether there is an abnormality, that is, whether there is a paper jam or a paper jam, based on the sensor detection signal. The signal control unit 60 is for performing control for validating or invalidating the input of the detection signal supplied from the optical sensor 48.

Next, the overall operation of the first embodiment will be described with reference to FIGS. 4 and 5. It should be noted that FIG. 4 shows a flowchart of the operation, and FIG. 5 shows the state of roll paper feeding. In this embodiment, the distance between the cutting position of the cutter 32 and the detection position of the optical sensor 48 is the width of the ticket, that is, an integral multiple of the mark pitch. That is, FIG.
As shown in (A), the cutter 32 and the optical sensor 48 are at the position of the stop mark M. Further, the optical sensor 48 is in an OFF state in which the mark detecting operation is not performed, that is,
The light emitter is not energized (not emitting light).

(1) Normal Operation First, the normal operation will be described. When a ticket is issued in response to a coin operation, a button operation for issuing a ticket, or the like (step S1 in FIG. 4), the forward pulse output unit 52 of the controller 50 outputs a forward pulse to the pulse motor 46 ( Step S2). Then, the pulse motor 46 rotates in the normal direction, and the roll paper 14 is sent out by the operation shown in FIG. 2 (A) (step S3). As a result, FIG. 5 (A)
The roll paper 14 at the position is sent out in the direction of the cutter 32 as shown in FIG. This operation is for roll paper 1
4 is repeated until the length LA shown in FIG. 5C is transmitted (step S4). Note that LA is a value slightly shorter than the interval LM between the marks M.

Then, the forward rotation pulse output section 52 outputs a signal indicating that the roll paper 14 has been LA-fed, and the signal control section 60 is brought into a signal valid state based on this signal. At the same time (or before that), the light emitting device of the optical sensor 48 is energized to turn on the sensor (step S).
5). That is, as shown in FIG.
Is sent and the feed amount becomes LA, the optical sensor 48
The mark can be detected by.

Thereafter, the roll paper feeding is continued until the mark M is detected by the optical sensor 48 (steps S6, S7, S8). During normal operation,
As shown in (D), the roll paper 14 has Δ (= LM−L
A) When sent, the mark M will be at the position of the optical sensor 48, and the mark M will be detected (step S).
6). Then, the detection signal is output from the optical sensor 48,
This is supplied to each unit via the signal control unit 60 of the control device 50 (step S9).

After the mark is detected, the signal control unit 60 becomes the signal invalid state, and at the same time (or after that), control is performed to turn off the optical sensor 48 (step S10). Further, the output of the forward rotation pulse is stopped and the reverse rotation pulse is output from the reverse rotation pulse output unit 54, so that the pulse motor 46 is rotated in the reverse direction (step S11). Then, by the operation shown in FIG. 2B, the roll paper feed is stopped in the state of FIG. 5D, and the cutter 32 is driven to cut the roll paper 14 (step S1).
2). By the above operation, one ticket TK is issued as shown by an arrow F3 in FIG.

FIG. 6 shows the relationship between the operating state of the signal control unit 60 and the operating state of the optical sensor 48 in the above operation with the roll paper 14 fixed. Same figure (B)
As shown in, the signal control unit 60 changes from the invalid state of the sensor detection signal to the valid state at the position PA before Δ from the mark M. Then, at the position PB where the mark M is detected, the signal valid state is changed to the invalid state.

Therefore, even if the optical sensor 48 is turned on in the state where the ticket issuing instruction of FIG. 5A is given and the mark M detected previously is erroneously detected, the signal control unit 60 is in the signal invalid state. Therefore, malfunction of each part of the control device 50 can be effectively prevented.

Next, in the example shown in FIG. 6C, the optical sensor 48 is turned on according to whether the signal control unit 60 is valid or invalid.
Turns off. Further, in the example shown in FIG. 7D, when the signal control unit 60 becomes valid from invalid, it is turned on before that.
Then, when the signal control unit 60 is changed from valid to invalid, it is turned off thereafter. That is, while the signal control unit 60 is valid, the optical sensor 48 is surely controlled to be ON.

As a result of such control, the light emitter of the optical sensor 48 is only energized for the period required for detecting the mark M, and the LA period shown in FIG. 5 (C) (see FIG. 6 (D)). In this case, it is not energized during a period slightly shorter than LA). Therefore, the life of the light emitter can be extended. This is effective when a light emitting diode, such as a light emitting diode, whose life is determined by the total energization time is used.

(2) Operation when ticket is out or jammed In this case, even if the pulse motor 46 is driven in the forward direction to feed the roll paper 14, the mark M is detected by the optical sensor 48 because the ticket is out or jammed. Cannot be detected. FIG. 5 (E) shows a situation when a ticket is jammed, and the mark MA that should be detected during normal operation is the optical sensor 48 due to the jam of the ticket.
Does not reach the position. FIG. 6F shows a state when the ticket is out, and the mark MA that should be detected during normal operation does not exist because the ticket is out.

Therefore, in this embodiment, when the mark M cannot be detected even when the roll paper 14 is further fed LB (see FIG. 5C) from the time when the sensor output is made effective (N in step S6, and S7). Y), it is determined to be abnormal. That is, when the abnormality determination unit 58 of the control device 50 has a signal input indicating that the roll paper 14 has been LB sent from the forward rotation pulse output unit 52 and no detection signal is input from the optical sensor 48, an abnormality has occurred. Is determined (step S1)
3).

When it is determined that an abnormality has occurred, for example, the pulse output by the pulse output units 52 and 54 is stopped to stop the roll paper feeding and cutting operations, the sensor output is invalidated, and the optical sensor is turned off. Etc. are processed. In addition, a warning buzzer (not shown) may be sounded, a warning lamp (not shown) may be turned on and off, or both the buzzer may sound and the lamp may blink.

As described above, according to the first embodiment, when the optical sensor approaches the mark, the mark detection is performed by validating the output of the optical sensor. One ticket will be issued. Further, the light emitter of the photosensor is energized and turned on only during the period when the photosensor output is valid or before and after the period, so that the life of the photosensor is extended.

Further, since it is determined that the mark cannot be detected even if the roll paper feed operation is performed for one pitch or more of the mark, it is determined that the mark is not abnormal, and the abnormality such as the out-of-ticket condition or the jam of the ticket is detected. It can be detected by one sensor means, and the number of steps for adjusting each sensor can be reduced, the number of parts can be reduced, the device configuration can be simplified, and the size and cost can be reduced. Note that step S20 in FIG. 4 will be described later.

<Second Embodiment> Next, a second embodiment of the present invention will be described with reference to FIG. In the above-described embodiment, the distance between the cutting position of the cutter 32 and the detection position of the mark detection sensor 48 is an integral multiple of the width of the ticket, that is, the mark pitch LM (see FIG. 5). That is, as shown in FIG. 5A, the cutter 32 and the mark detection sensor 48 are at the position of the stop mark M. On the other hand, the present embodiment is a general case in which the distance between the cutting position of the cutter 32 and the detection position of the mark detection sensor 48 is not necessarily an integral multiple of the mark pitch LM.

In the example shown in FIG. 7 (A), the mark detection sensor 48 is displaced from the mark position by L1. In the example shown in FIG. 6E, the mark detection sensor 48 is displaced by L2 from the mark position. In addition,
The relationship is L1 <L2 <LM.

In the case of FIG. 7A, the feed length in step S4 during the operation shown in FIG. 4 is set to the distance LA shown in the same figure. Then, after issuing the ticket issuing instruction (step S1), the roll paper 1
4 is sent by LA in the same manner as in the above embodiment (step S2,
S3, S4). FIG. 7B shows a state in which the roll paper 14 has been sent to the LA, and at this time, the control device 50 is set to the sensor detection signal valid state and the mark detection sensor 48 is turned on (step S5). .

When there is no abnormality, mark detection is performed when the mark M reaches the sensor position as shown in FIG. 7C (Y in step S6), and the sensor detection signal is disabled and the mark is detected. The detection sensor 48 is turned off (step S10).

Next, in this embodiment, when the mark M is detected, the forward rotation pulse output section 52 of the control device 50 further feeds the roll paper 14 by the predetermined amount L1 (step S20). Then, the roll paper 14 is fed from the mark detection position of FIG. 7C by L1 and reaches the position shown in FIG. At this position, the roll paper 14 is fed out for one ticket, and the mark M is just at the position of the cutter 32. Therefore, the roll paper 14 is cut by the cutter 32, and one ticket is issued (steps S11 and S12), as in the above embodiment.

Next, when the ticket is out or jammed, the above L
After the roll paper feed of A (step S4), the same operation as that of the above-described embodiment is performed (steps S7 and S8). And L
When the mark M is not detected while sending B, it is determined that an abnormality has occurred (step S13). The subsequent steps are the same as in the above embodiment.

The same applies to the case of the example shown in FIG. In this case, the first feed length LA of the roll paper 14
Is set shorter than that in FIG. The LBs have the same length in each case. The roll feed length after the mark is detected is L2 in the case of FIG.

As described above, according to the second embodiment, after the mark is detected, the roll paper is fed by a predetermined amount to the position where the bill is cut, and then the bill is cut from the roll paper. In this case,
The total of the roll paper feed length from the ticketing instruction until the mark is detected and the roll paper feed length from the mark detection to the position where the ticket is cut are equivalent to the feed length of one roll paper ticket. To do. Then, when the mark cannot be detected even if the roll paper is fed by a length capable of detecting the mark, it is determined that the ticket has run out or jammed.

As a result, similar to the above-described embodiment, it is possible to prevent erroneous mark detection, prolong the life of the optical sensor, and reduce the number of parts to simplify the device structure, reduce the size, and reduce the cost. In addition, according to the second embodiment, since the roll paper is fed by a predetermined amount after the mark is detected, the positional relationship between the cutter and the mark detection sensor is excellent regardless of the mark pitch. Tickets can be issued.
Tickets can be issued even when the mark is not on the boundary between the tickets, for example, when the mark is in the center of the ticket. In the first embodiment, L1 or L2 is “0” in the second embodiment.
Can be considered a special case of.

<Other Embodiments> The present invention is not limited to the above embodiments, and includes, for example, the following. (1) The present invention relates to mark detection control, and mechanical mechanisms such as roll paper feeding and cutting may be appropriately changed as necessary. For example, a tension mechanism for preventing the slack of the roll paper, a rotation speed adjustment mechanism for adjusting and transmitting the rotation speed of the pulse motor to set the roll paper feed speed and the cutter drive speed to predetermined values, and the cutter If necessary, a counting mechanism for counting the number of issued tickets based on the number of times the movable blade has moved may be provided. The planetary gear mechanism also
It may be another mechanism having the same action, for example, a gear switching mechanism. Depending on the gear mechanism, the relationship between the forward rotation and the reverse rotation of the pulse motor is also the opposite relationship to the above embodiment.

(2) In the above embodiment, the mark is formed on the roll paper and the mark is detected by utilizing the fact that the light is reflected or absorbed by the mark. However, the roll paper is notched or punched. The mark may be formed by a method of performing processing such as the above, and the mark may be detected based on the presence or absence of light transmission. (3) In the above embodiment, the optical sensor is used as the mark detecting means, but a magnetic material such as magnetic ink may be used to detect the mark using the magnetic sensor.

(4) In the above embodiment, the optical sensor is turned on only for a certain period required for mark detection to prolong the sensor life. However, the purpose is only to prevent erroneous detection by effective / ineffective control of the sensor detection signal. In this case, it does not prevent continuous turning on of the optical sensor. (5) The control device may be executed by software using a microcomputer or the like.

[0046]

As described above, the ticket issuing machine according to the present invention has the following effects. (1) Since the control for validating and invalidating the output of the mark detecting means is performed, the re-detection of the same mark is prevented, and a ticket issuing machine that does not malfunction can be provided. (2) Since the start / stop of the operation of the mark detecting means is controlled in response to the valid / invalid of the output of the mark detecting means, the life of the mark detecting means can be extended.
