JPH10188053A - Remaining quantity detector for rolled paper and ticket issuing device - Google Patents

Abstract

PROBLEM TO BE SOLVED: To exactly detect the remaining quantity of rolled paper without applying any conveyance load to the rolled paper by optically detecting the rotating angle of rotary shaft at time, when the rolled paper is fed out for prescribed quantity, with no contact and detecting the remaining quantity of rolled paper from the displacing amount of this detected angle. SOLUTION: When rolled paper 2 is fed out by ticket issuing operation, a rotary shaft 31 is rotated and a disk 32 is rotated by this rotation. At this time, a light emitting part 34a of sensor 34 emits light. Since this light is passed through a slit from the state of being shielded by the disk 32, this is received by a light receiving part 34b. Each time the light receiving part 34b receives this light, namely, each time the slit is detected, its detecting signal is sent to a detecting means 35 and at the detecting means 35, the displacing amount of rotating angle of rotary shaft 31 of rolled paper 2 is detected from the number of slits detected while one piece of rolled paper is issued. Thus, the load at the conveying time of rolled paper is reduced and further, the remaining amount of rolled paper can be detected without damaging it.

Further, the roller paper 2 is provided on the delivery side of the roll paper 2.
Is provided with a sensor 41 for detecting the presence / absence. next,
The ticketing operation will be described.

First, the roll paper 2 is set in the loading section 2A, the leading end thereof is pulled out, wrapped around the feed roller 4, and fed out by the rotation of the feed roller 4. The unwound roll paper 2 is fed to the first and second transport roller pairs 5 and 5.
6 is fed along the transport path 3 by the rotation of the feed roller 6, and when the leading end is detected by the sensor 10, the feed rollers 4,
The rotation of the first and second transport roller pairs 5, 6 is stopped. With this stop, the roll paper 2 is stopped at the fixed position. The roll paper 2 stopped at this position is cut by the third cutting unit 12 at a ticket length of 30 mm when a ticket is issued, and 8 mm by the second cutting unit 8 when a commuter pass is issued.
It is cut with a 5mm ticket length, and when issuing a green ticket or the like, it is cut with a 120mm ticket length.

The bills cut by the first to third cutting sections 7, 8, and 12 are made up of a thermal head 9 and a platen roller 9a.
And various information such as a station name, a section, and a fee are printed on the front side (printed portion). After being printed in this manner, the ticket was sent to the write magnetic head 15 where the information was magnetically recorded on the back side (magnetic recording portion), and then sent to the read magnetic head 16 where it was magnetically recorded. The information is read and its contents are confirmed. If the result of the check by the magnetic reading head 16 is correct, the bill is conveyed to the bill outlet 11 and discharged. If the result of the check by the magnetic reading head 16 is not correct, the bill is sent to the disposal conveyance path 19 through the gate 20 and
After being perforated in step 1, it is collected in a waste ticket box 22 as a waste ticket.

When the old ticket is processed for refund or cancellation, the old ticket is inserted through the slot 23, the magnetic information is read by the read magnetic head 16, and then the write magnetic head is Rewrite (or demagnetize) magnetism by 15
Then, the paper is sent to the perforation section 21 via the disposal conveyance path 19, where it is perforated and collected in the waste ticket box 22.

By the above-described series of ticketing operations, the remaining amount of the roll paper 2 is reduced, or finally, completely eliminated.
Therefore, it is necessary to detect the remaining amount of the roll paper 2 and notify the operator of the remaining amount.

FIGS. 2 and 3 show a remaining amount detecting device 30 for detecting the remaining amount of the roll paper 2. In the figure, reference numeral 31 denotes a rotation shaft for rotating the roll paper 2, and a disk 32 for detecting the rotation angle is provided at one end of the rotation shaft 31. A number of slits 33 are radially formed in the disk 32 in the circumferential direction. The lower side of the disk 32 has a U-shaped cross section, and the slit 3 of the disk 32
3 is provided.

The sensor 34 is a light emitting element 34a that emits light.
And a light receiving element 34b for receiving the light emitted from the light emitting element 34a. The detection unit 35 is connected to the light receiving element 34b via a signal circuit 36. Detector 3
Numeral 5 detects the amount of displacement of the rotation angle of the rotating shaft 31 during the issuance of one note, based on the number of light receptions sent from the light receiving element 34b during the issuance of one note.

Next, a case where the remaining amount of the roll paper 2 is detected will be described. When the roll paper 2 is fed out by the ticketing operation, the rotating shaft 31 is rotated, and the rotation of the rotating shaft 31 rotates the disk 32. At this time, light is emitted from the light emitting portion 34a of the sensor 34, and the light passes through the slit 33 from a state where the light is blocked by the disk 32, and is received by the light receiving portion 34b. Light receiving unit 34b
Each time receives the light, that is, every time the slit 33 is detected, the detection signal is sent to the detection unit 35 and the detection unit 3
In 5, the rotation axis 3 of the roll paper 2 is determined based on the number of slits 33 detected during the issuance of one sheet of paper (the dimension 1 of the roll paper 2).
The amount of displacement of one rotation angle is detected.

As shown in FIG. 4, the rotation angle α of the rotation shaft 31
Is small, the remaining amount of the roll paper 2 is large,
As shown in FIG. 5, when the rotation angle β is large, the remaining amount of the roll paper 2 is small, and when the rotation angle becomes a certain angle or more, the determination means 36 shown in FIG. When it is determined that there is a displacement and the amount of displacement of the rotation angle cannot be detected, as shown in FIG. 6, the remaining amount of the roll paper 2 is completely lost, and the disk 32 remains stopped without rotating, and the roll paper 2 remains stopped. 2 is determined to be the end.

When the determination means 36 determines that the roll paper 2 is near end or end, the display section 37 displays the near end or end of the roll paper 2. The operator looks at this display and replenishes the roll paper 2.

When the roll paper 2 is slack as shown in FIG. 7, the disc 32 may not rotate even if the roll paper 2 is fed out. In order to eliminate this adverse effect, the judging means 35 judges that the roll paper 2 is at the end for the first time, for example, when the disk 32 has not been rotated even if three or more tickets are issued continuously. Thus, it is possible to prevent a state in which the roll paper 2 is slackened from being erroneously determined as a paper-out state.

The number of sheets to be continuously issued may be determined in consideration of slack of the roll paper 2 by a ticketing apparatus incorporating this mechanism. Further, the sensor 41 provided on the roll paper 2 feeding side is used when the roll paper 2 is fed out,
Despite the rotation of the rotating shaft 31 of the roll paper 2,
When detecting that the roll paper 2 has no paper on the feeding side, the determination unit 36 determines that the sensor 41 is abnormal, and causes the display unit 37 to display the sensor abnormality. The operator replaces the sensor 41 while seeing the display of the sensor abnormality.

[0033]

As described above, according to the present invention, the remaining amount of roll paper is optically detected in a non-contact manner. Can be reduced, and the remaining amount of roll paper can be detected without damaging the roll paper.

Further, as compared with the case where the number of issued tickets is counted and the remaining amount is estimated, there is no influence due to the variation of the length of the roll paper, so that the remaining amount of the roll paper can be detected more accurately. .
