Pulling means for pulling out the roll paper of one roll, and control means for controlling switching so as to pull out the roll paper of the next roll when the roll paper of one roll is consumed to an unusable state. Is what you do.

According to this roll paper supply device, when a request for discharging an admission ticket or the like is made by inputting money or the like, the roll paper is pulled out from one of the plurality of loaded rolls by the driving of the pulling means and pulled out. After the predetermined portion is subjected to a predetermined process, the processed portion is cut into an entrance ticket or the like, and the entrance ticket or the like is discharged.

When the roll paper of one roll is low enough to be unusable, the roll paper is pulled out from another unused roll under the control of the control means.
Subsequently, the entrance ticket and the like from the next roll are discharged. Therefore, it takes a long time to load a new roll as in the related art, so that there is no inconvenience of making the customer wait, and this is effective in preventing a decrease in service.

According to a second aspect of the present invention, there is provided the roll paper supply apparatus according to the first aspect, wherein the pull-out means is disposed so as to be separated from and connected to the roll paper through the pulled-out roll paper. One roll is formed by a pair of detachable pull-out rollers, and at least one of the pair of pull-out rollers is a driving roller that pulls out roll paper by driving rotation about an axis.

According to this roll paper supply apparatus, the roll paper is sandwiched by a pair of pull-out rollers corresponding to the roll from which the roll paper is drawn, and the roll paper is held in a state where the pair of rollers corresponding to the other rolls are separated. By driving the pair of rollers driving the pair of rollers, only the roll paper of the roller to be pulled out is pulled out. As described above, the roll paper is stopped and pulled out by the separation and contact of the pair of rollers, so that the structure for selectively extracting the roll paper is simplified.

According to a third aspect of the present invention, there is provided the roll paper supply apparatus according to the second aspect, wherein the roll paper drawn from the plurality of rolls is sequentially arranged downstream of each of the pair of pull-out rollers.

At the position, there are two layers together with the previous roll paper, and the number of layers increases sequentially toward the downstream side. Accordingly, first, the pair of rollers on the most upstream side sandwich the roll paper on the most upstream side and drive the drive roller to discharge an entrance ticket or the like by the roll paper on the most upstream side. Then, when the next pair of rollers is approached after the uppermost stream roll has run out, the next roll paper is pinched by the pair of rollers because the uppermost stream roll already does not exist at this time. And the next roll paper is pulled out by the drive of the drive roller. Each time the upstream roll paper runs out, by bringing the pair of rollers on the downstream side closer together, one roll paper to be pulled out is always sandwiched by the pair of rollers, and the transfer of the roll paper is efficiently performed. And the roll paper takeover structure is simplified.

According to a fourth aspect of the present invention, in the roll paper supply apparatus according to any one of the first to third aspects, the detecting means for detecting the presence or absence of the roll paper drawn from each roll is provided. It is characterized by being provided.

As shown in this figure, the control means 7 determines that a roll R (first roll R1 and second roll R2) is loaded on a pair of paper shafts 23, respectively, and a roll paper P (first roll paper P1).
The control is started by turning on a predetermined start switch in an initial state in which the leading end of the second roll paper P2) is introduced into the respective transport paths (the first transport path 5a and the second transport path 5b). It has become.

When the start switch is turned on, first, detection signals from the first and second detection sensors 71 and 72 are input to the control means 7 to determine whether or not the roll paper P is properly set. It is determined.

Also, in the appropriate place of the frame 11 (FIG. 1),
An input means 75 having ten keys and input buttons for inputting a desired entry ticket such as an entrance ticket P0 is provided.
When an input signal from the input means 75 is input,
A drive signal is sequentially output to the feed motor 31, the auxiliary motor 45, the thermal head 41, the ribbon winding motor 43a, and the roll paper cutting unit 6.

Then, a drive signal is outputted from the control means 7 to the first solenoid 36a in synchronization with the drive of the feed motor 31, and the first link arm 38a is caused to change its posture from the separated posture to the contact posture by the first solenoid. Roll paper P1
Is held between the first pressing roller 39a and the first conveying roller 32, and is pulled out by the counterclockwise rotation of the first conveying roller 32 via the upstream endless belt 30, so that the first conveying path 5a is moved toward the downstream side. At this time, since the pull-out of the second roll paper P2 is regulated by the lock lever 89, the second transport roller 33
It will not be pulled out regardless of the rotation of.

Then, when the leading end side of the first roll paper P1 is carried right below the thermal head 41 by the clockwise rotation of the downstream endless belt 450 driven by the auxiliary motor 45, the control means 7 sends the third pressing means 48. Solenoid 4
A drive signal is output to 8a, whereby the leading end of the first roll paper P1 is pressed against the thermal head 41 by the pressing roller 48d. In this state, the ribbon winding motor 43a and the thermal head 41
Is output by the thermal head 41 so that the ink of the ink ribbon I forms predetermined characters on the surface of the first roll paper P1.

Next, when the printed portion of the first roll paper P1 passes between the pair of upper and lower cutting blades 61, a drive signal from the control means 7 is output to the roll paper cutting section 6, and this drive is performed. The first roll paper P1 is cut by the cutting operation of the cutting blade 61 by a signal to form an entrance ticket P0 and the like, and the entrance ticket P0 is discharged to the tray 13.

By repeating the issuance of the admission ticket P0 and the like a predetermined number of times, the remaining amount of the first roll paper P1 wound on the first roll R1 decreases, and the end mark is detected by the first detection sensor 71. When detected, this detection signal is input to the control means 7. Then, the control means 7 to which the detection signal has been input determines that the first roll paper P1 has run out, and outputs a control signal of reverse drive to the feed motor 31. The first roll paper P1 that has entered the transport paths 5a, 5b, and 5c is pulled back by the clockwise rotation of the first transport roller 32, and the first detection sensor 7
The feed motor 31 is stopped when the first roll paper P1 no longer detects the presence of the first roll paper P1.

Next, the control means 7 controls the drawer restricting means 8
A drive signal is output to the solenoid 81, and the restriction of the lock lever 89 on the second roll paper P2 is released by the plunger 82 being retracted. Subsequently, the control means 7 controls the feed motor 31 and the second solenoid 36b.
Endless belt 3 to output a drive signal toward
0, the second roll paper P2 pressed and sandwiched between the second transport roller 33 and the second pressing roller 39b is pulled out by the forward drive of the second transport roller 33, and thereafter the second roll paper P2 is moved to the second roll paper P2. A similar printing process is performed.

FIG. 5 is a flowchart showing one embodiment of the control flow by the control means 7. This flowchart shows the state at the time when the first roll paper P1 is switched to the second roll paper P2. Therefore, the normal control for the roll paper P is represented by "ticketing" in step S1. Each time a ticket is issued, the first
It is determined whether or not the detection sensor 71 has detected the end mark of the first roll paper P1 (S2). If YES is detected when the end mark has been detected, the reverse rotation drive is performed after the feed motor 31 is locked (S3). Is performed (S4). By the reverse rotation drive of the feed motor 31, the first roll paper P1 is pulled back from the transport paths 5a, 5b, 5c.

Next, the presence or absence of the first roll paper P1 (whether the first roll paper P1 is no longer detected) is detected by the first detection sensor 71 (S5).
The feed motor 31 is temporarily stopped (S6), and then the second solenoid 36b is turned on, so that the second roll paper P2 is pressed and nipped by the second transport roller 33 and the second pressing roller 39b (S7). .

In this state, the solenoid 81 of the pull-out restricting means 8 is turned on, whereby the restriction of the second roll paper P2 by the lock lever 89 is released, and the second roll paper P2 can be pulled out (S8). In this state, a ticketing process similar to that in step S1 is executed for the second roll paper P2. Then, in step S10, the presence or absence of the end mark of the second roll paper P2 is detected by the second detection sensor 72, and when the end mark is detected, the control is terminated and the business by the roll paper supply device 1 is stopped.

As described in detail above, the roll paper supply device 1 of the present invention draws out the roll paper P by a predetermined size every time a request is received from the roll R on which the long roll paper P is wound, and performs a predetermined process. After the application, the entrance ticket or the like P0 formed by separating the processed portion of the roll paper P is discharged, and corresponds to a plurality of rolls R arranged side by side.
A drawer 3 for drawing out each roll paper P independently of the other roll paper P; and a roll paper P of the next roll R when the roll paper P of one roll R is consumed to a state where it cannot be used.
Control means 7 for switching control so as to pull out a roll paper P from a plurality of loaded rolls R when a request to discharge an entrance ticket or the like P0 is made by inserting money or the like. After being driven out, a predetermined process is performed on the drawn-out portion, and then the cut-off entrance ticket or the like P0 is discharged.

When the roll paper P of one roll R is low enough to be unusable, the control means 7 controls the roll paper P to be pulled out from another unused roll R. P0 from the entrance ticket
Is discharged. Accordingly, it takes a long time to load a new roll R as in the related art, and there is no inconvenience such as waiting for the customer, and it is possible to reliably prevent a decrease in service.

Further, the pull-out section 3 is provided with a pair of detachable pull-out rollers (a first transport roller 32 and a first transport roller 32) per roll R, which are disposed so as to be separated from each other via the roll paper P pulled out. Holding roller 39a and second transport roller 3
3 and the second pressing roller 39b), and at least one of the pair of pull-out rollers (the first transport roller 32 and the second transport roller 33) is a drive roller that pulls out the roll paper P by driving rotation about the axis. As a result, the roll paper P is pinched by a pair of pull-out rollers corresponding to the roll R from which the roll paper P is pulled, and the other rolls R
By driving the pair of rollers that hold the roll paper P in a state in which the pair of rollers corresponding to the pair of rollers are separated, only the roll paper P of the roller to be pulled out can be pulled out. As described above, the pull-out of the roll paper P is stopped and pulled out by the separation and contact of the pair of rollers, so that the selective pull-out structure of the roll paper P can be simplified.

Further, a plurality of rolls R (first roll R1 and second roll R2) are juxtaposed so that the rolled paper P is stacked, and a pair of pull-out rollers for one roll R is provided. By disposing a pair of rollers that draws out the roll paper P on the upstream side of the pair of adjacent front and rear draw rollers, on the upstream side of the drawn out roll paper P on the downstream side, The pulled out roll paper P has a single layer at a pair of roller positions corresponding to the roll paper P, and has two layers at the pair of roller positions corresponding to the next roll R together with the previous roll paper P. Accordingly, by first nipping the upstream roll paper P between the pair of rollers on the upstream side and driving the drive roller, an entrance ticket P0 or the like using the roll paper P on the upstream side can be formed.
Then, when the next pair of rollers is approached after the upstream roll paper P has run out, the next roll paper P is nipped by the pair of rollers because the upstream roll paper P no longer exists at this time. Then, the next roll paper P can be pulled out by driving the drive roller.
Each time the upstream roll paper P runs out, by bringing the pair of downstream rollers closer together, one roll paper P to be pulled out is always held between the pair of rollers, and the roll paper P is taken over. Can be performed efficiently, and the takeover structure of the roll paper P can be simplified.

Further, by providing a detecting means for detecting the presence or absence of the roll paper P pulled out from each roll R, switching to the downstream roll R when the upstream roll R runs out can be efficiently performed without time lag. It can be carried out.

Further, by providing a drawer restricting means for restricting the drawing of the roll paper P from the roll R which is not the target of drawing, even if a plurality of sheets are stacked, they can be drawn. It is possible to avoid such a problem that the roll paper P is erroneously pulled out due to friction.

The present invention is not limited to the above embodiment, but includes the following contents.

(1) In the above embodiment, the rolls R are juxtaposed such that the roll paper P pulled out passes through the same transport path to the discharge port. For example, a pair of rolls R are arranged concentrically side by side, and a transport path dedicated to the roll paper P drawn out from each roll R is provided. When one roll R is exhausted, a dedicated transport path is set from the other roll R. It may be configured to discharge the roll paper P by using this.

(2) In the above embodiment, the ticket vending machine is capable of mounting only two rolls R. However, the present invention provides a ticket vending machine capable of mounting only two rolls R. Is not limited to three or more rolls R
May be configured to be attached.

(3) In the above embodiment, the first roll R1 is consumed and then switched to the second roll R2. When the second roll R2 is used up, the driving of the ticket vending machine is temporarily stopped. Instead of loading two new rolls, instead of this, the first roll R1 is exhausted and then switched to the second roll R2, and the new first roll R2 is opened while operating with the second roll R2. Load the roll R1,
When the second roll R2 is consumed, the original roll may be switched to the first roll R1, and this operation may be sequentially repeated. In this way, it is possible to continue the operation of the ticket vending machine without giving the customer a waiting time.

(4) In the above embodiment, when it is detected that the roll paper P of the first roll R1 is running low, the roll paper P is temporarily moved in the reverse direction to thereby remove the second roll R2. Only the roll paper P is sandwiched between the second transport roller 33 and the second pressing roller 39b, but instead of this, the roll paper P of the first roll R1 that has run out is pulled out, and Then, the roll paper P of the second roll R2 is transported to the second transport roller 33.
And the second pressing roller 39b.
