Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a feeding device that feeds out the base paper from a holding portion of the roll of base paper and supplies it to a processing section. The present invention relates to a terminal end detection device for roll-shaped base paper that detects the end of a rolled base paper.

(Prior art) Conventionally, base paper for various cards, printed matter, etc. has been formed into a long length in advance and wound into a roll, the roll of base paper is rotatably held, and the base paper is fed out from the holding portion of the roll of base paper. Various devices are known in which the information is supplied to a processing section, and the processing section performs processing such as printing and cutting. For example, as shown in Japanese Unexamined Patent Application Publication No. 61-217889, when a ball lending card made of a magnetic card or the like is used to lend game media such as pachinko balls, the ball lending card is used as a currency. A ticket issuing machine that issues tickets in response to input is equipped with a base paper supply device that rotatably holds the base paper of a ball loan card that has been formed into a long length and rolled into a roll, and the base paper is transferred from this base paper supply device to a processing section. There is one in which a predetermined ball rental card is created by supplying the ball and performing processing such as printing, cutting, and magnetic recording in a processing section.

By the way, when roll-shaped base paper is fed out as it is used, a detection device is required to detect when the base paper has been fed out to the vicinity of the end and there is almost no remaining amount for replacement, etc. . Conventionally, as this type of detection device, a microswitch is installed at a position that comes into contact with the base paper roll held at a predetermined location of the base paper supply device, and when the base paper roll becomes small in diameter due to the base paper being fed to the vicinity of the end. It is known that detection is performed by switching a microswitch accordingly.

However, according to this detection device, since the change in the diameter of the base paper roll for each roll of base paper is extremely small, it is inevitable that a relatively large error will occur in the end detection by the microswitch. In order to prevent a situation where the end of the base paper is not detected even when the end of the base paper is reached, the microswitch should be set to switch when a considerable amount of base paper remains to allow for the above error. There is a need. Therefore, when the base paper is at its shallowest position, it is determined that the base paper is used based on the detection by the microswitch, and the base paper roll is replaced, resulting in a considerable waste of base paper. Furthermore, if a microswitch is used,
It was difficult to finely adjust the stroke (stroke adjustment), and there were also problems in terms of durability.

(Object of the Invention) In view of the above circumstances, the present invention is capable of accurately detecting the end of a roll of base paper that is gradually unwound as it is used, when it has been unwound to the end, thereby making efficient use of the base paper. The present invention provides a device for detecting the end of rolled base paper, which can be used for various purposes, and which is also advantageous in terms of time adjustment and durability.

(Structure of the Invention) The present invention is provided in a feeding device that rotatably holds a long base paper wound into a roll, and feeds the base paper from the rolled base paper holding portion and supplies it to a processing section. A terminal end detection device for roll-shaped base paper, wherein a colored mark is attached to the outer surface of the terminal end of the base paper, and an optical sensor for detecting the mark is provided at a predetermined location around the roll-shaped base paper holding part. It is something that

According to this configuration, when the mark is exposed by unwinding the rolled base paper to the end and reaches a position corresponding to the sensor, the end is accurately detected.

Such a ball lending card 5 is created by cutting with a cutting means.

In addition, in a ball rental system using such a ball rental card 5, in addition to the ticket issuing machine 1, there is also a machine (not shown) that rents balls (discharges a predetermined number of pachinko balls) in response to the insertion of a ball rental card. A ball lending machine, a tallying machine that tallies and manages ticketing and ball lending, etc. are installed, and from ticket issuing machine 1 to ball lending card 5
When the ball lending card 5 is inserted into the ball lending machine, the contents of the barcode 25 are compared with the information stored in the counting machine. Tama lending is now held at the top.

A specific example of a roll-shaped base paper end detection device applied to the base paper supply section A of the paper rental unit 111 will be described below with reference to FIGS. 3 and 4.

As shown in FIG. 3, the base paper roll 6 held in the base paper supply section A has a colored mark 30, for example, a black band-shaped mark 30, on the outer surface of the end of the base paper in advance. . As shown in FIG. 4, the base paper roll 6 is attached to a cylindrical shaft 31 and rotatably and vertically movable to a holding frame 32 provided in the base paper supply section A. In addition, it is supported by a pair of support rollers 33, and as the base paper 7 is fed out by the operation of the feeding mechanism B, the lower end of the base paper roll 6 is kept in contact with the support rollers 33 due to its own weight. The base paper roll 6 is designed to rotate. Furthermore, the base paper roll 6 is held in a holding frame 32 so that it can be replaced when it is used.
It can be removed from. This holding frame 32 and the support roller 33 constitute a rolled base paper holding portion.

An optical sensor (hereinafter referred to as an end sensor) 34 for detecting the mark 30 is provided at a predetermined location on the periphery of the rolled base paper holding portion. The end sensor 34 detects when the base paper is fed out until the mark 30 is exposed and reaches the position corresponding to the end sensor 34. The end sensor 34 is arranged at the lower part of the holding frame 32, and is used to detect when the base paper roll is exposed. It faces the outer surface of 6 from below. Further, in this embodiment, a near-end sensor 35 is attached to the holding frame 6 on the side of the base paper roll 6 to detect when the base paper has been fed out to the vicinity of the end. When the diameter of the base paper roll 6 becomes smaller as the base paper is fed out to the vicinity of the end, this is detected by not receiving the reflected light. ing. In addition, a sub-switch 36 consisting of a microswitch may be provided at a predetermined location on the holding frame 32 as shown in the figure as a backup end detection means in case the end sensor 34 and the near-end sensor 35 fail. .

In the ball lending machine 1 of this embodiment in which the end detection device as described above is incorporated in the base paper supply section A, the above-mentioned feeding mechanism B,
By operating the thermal printing means C and the cutting means, a ball rental card 5 is created and issued, and the base paper 7 is fed out from the base paper roll 6 along with this ticket issuing operation. By repeating such an operation, when the base paper is fed out to a state where the mark 3o at the end of the base paper is exposed and reaches the position corresponding to the end sensor, the mark 30 is detected by the end sensor 34, and as a result, The end of the original paper is detected correctly. Then, the base paper is used until the end is detected, and when the end is detected, the control unit 23 that receives the signal stops the ticket issuing operation and instructs that the base paper 11 to roll 6 should be replaced. Processing such as displaying to show the information is performed.

Control of ticket issuing operation and control based on termination detection by the control unit 23 are performed, for example, according to the flowchart shown in FIG.

That is, in this flowchart, first, in step S1, a ticket issue request signal given from the currency identification bag @4 and the requested number of tickets issued switch is input, and then, in step S2, signals from the end sensor 34 and the near-end sensor 35 are input. Enter. And step S3
It is checked whether the end sensor 34 has detected the end (detected a mark), and if the determination is YES, a flag indicating end detection is set (step 34). Further, in step S5, it is checked whether the near-end sensor 35 is ON or not, and when the determination is YES, a near-end display is performed by a display means such as a lamp provided on the ticket issuing machine or the totalizing machine (step Ss).

Although this near-end display is not necessarily required, it is useful for predicting when to replace the base paper roll.

Next, in step S7, it is checked whether the requested number of tickets to be issued is O or not. In this case, when a specified number of coins are inserted into the ticket issue 1fi1 and the switch for specifying the number of tickets to be issued is operated, the designated number is set as the requested number of tickets to be issued, and step S7
It is determined that the requested number of tickets to be issued is not O. In this case, the process moves to step S8, and one ball rental card is issued by operating the feeding mechanism B, thermal printing mechanism C, and cutting mechanism at predetermined timings, and furthermore, in step S9, the requested number of cards is issued. After incrementing, the process returns to step S2 and the subsequent processes are performed again. In this way, the issuance of ball lending cards is repeated until the requested number of issued tickets reaches O. That is, in the specific example shown in this flowchart, the ticket issuing operation is repeated from the time the ticket issuing request is issued until the specified number of ball rental cards are issued, regardless of whether the end sensor 34 detects the end. The reason why this is done is that even if the end sensor 34 detects the end, the base paper 7 is left in the area from the detection position to the processing section, and this base paper 7 allows the specified number of ball lending cards to be processed. This is because issuance is possible.

When it is determined in step S7 that the number of requested tickets is O, that is, if no ticket issuance request has been made, or if the issuance of the specified number of ball rental cards has been completed after the ticket issuance request, the flag is set in step Sv. By checking whether or not the end sensor 35 has detected the end. If the flag is not set, the process returns to step S1, but if the flag is set, processing is performed to stop issuing tickets in step s11, for example, stopping the taking in of currency by the carrying means 3 and Displays that ticket issuance is suspended. Furthermore, the ticket issue suspension state is maintained until the clear key provided in the ball lending machine 1 is turned on, step 5t.
1), when the clear key is turned on after replacing the base paper roll 6, the flag is reset (step 513);
Then, by returning to step S1, the state is made ready for ticket issuance processing again.

In the above embodiment, the present invention is applied to the base paper supply unit A of the ticket issuing machine 1 that issues ball rental cards using thermal paper, but the present invention is also applicable to printing or magnetic recording from rolled base paper. The device of the present invention can be applied to a base paper supply unit for producing various prepaid cards, printed matter, etc. through processing such as cutting.

(Effects of the Invention) As described above, the present invention attaches a colored mark to the outer surface of the end portion of a roll-shaped base paper, and at the same time, an optical system for detecting the mark is placed at a predetermined location on the periphery of the O-roll-shaped base paper holding portion. By providing a target sensor, this is detected when the base paper is fed out to the point where the mark is exposed and reaches the position corresponding to the sensor, so it is possible to detect when the roll of base paper has been fed out to the end. can be detected accurately. Therefore, it is possible to appropriately perform processes such as exchanging the rolled base paper based on the detection of the end, and it is possible to efficiently use the rolled base paper until the end. In addition, since detection is performed using an optical sensor that does not have moving parts, it is more durable than using a microswitch. Although fine adjustment is required and difficult to make, the present invention also has the effect of simplifying the time adjustment when installing the sensor.
