Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic ticket type discriminating apparatus, for example, which is installed in an automatic ticket gate for station service, and more particularly to a magnetic ticket type having a simplified discriminating structure of the ticket type used in the ticket gates. Regarding the discriminating device.

[0002]

2. Description of the Related Art Tickets generally used in automatic ticket gates,
A ticket type discriminating device for discriminating ticket types such as coupon tickets and commuter tickets is a high coercive ticket or a low coercive ticket by reading the magnetic data output with different coercive force and low coercive force recorded on the surface of the note. Alternatively, the type of non-coercive ticket is determined (see, for example, Japanese Patent Application No. 1-265807 of the prior application).

[0003]

In this case, a magnetic discriminating circuit for discriminating between the high magnetic coercive ticket and the low magnetic coercive sheet is required to discriminate between the magnetic coercive level and the non-magnetic coherent sheet. Since it is not possible to discriminate between a coercive sheet and a sheet with a peeled magnetic layer, there is a problem that the discriminating performance is unstable.

Therefore, an object of the present invention is to provide a magnetic note type discriminating apparatus capable of discriminating a note type from a specific magnetic processing condition without requiring a magnetic discriminating circuit and accurately discriminating the note type. To do.

[0005]

According to the present invention, there is provided a high coercive ticket which magnetizes magnetic data with a high coercive force on a bill surface, a low coercive ticket which magnetizes magnetic data with a low coercive force, and a magnetic data. A magnetic note type discriminating apparatus for reading and discriminating three types of non-coercive sheets, a write head for writing magnetic data of high coercive force on the note surface, and magnetic data for the note surface written by the write head. Among the data results of the reading head to be read and the face of the paper read by this reading head, when the read data and the write data are found to match, it is determined as a high-coercive ticket, and the read data and the write data are not found to match. It is characterized in that it is provided with a bill type discriminating means for discriminating a low coercive bill when there is no read data.

[0006]

According to the present invention, when discriminating the bill type, the bill type discriminating means causes the writing head to write magnetic data having a high coercive force on the bill surface, and the reading head reads the magnetic data. At this time, when the read data and the write data match and the read head allows the magnetic data with a high coercive force to be read, it is determined as a high coercive ticket, and when the magnetic data with a high coercive force cannot be read due to a mismatch, the low coercive force is read. If there is no read data, it is determined as a non-coercive ticket.

[0007]

As described above, the magnetic data of high coercive force is recorded on the face of the bill at the time of discriminating the bill type, and by reading and judging the data, the three types of the high coercive disc, the low coercive disc, and the non-coercive disc. It is possible to accurately determine either of the above. In particular, even a non-coercive sheet of blank paper can be accurately discriminated without being affected by a demagnetized sheet having the magnetic layer peeled off, and a highly reliable and stable discrimination process can be performed. Further, since it is not necessary to determine the magnetic output level, the determination circuit can be omitted, and the note type determination structure can be simplified and the cost can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. The drawing shows a magnetic ticket type discriminating apparatus equipped in an automatic ticket gate. In FIG. 1, the magnetic ticket type discriminating apparatus includes a writing head 12 arranged at a starting end side of a main conveyance path 11 for conveying and processing a ticket. It is composed of a reading head 13, a discharge conveyance path 14 and a collection conveyance path 15 which are branched and connected to the terminal side of the main conveyance path 11. Each of the above-mentioned transport paths 11, 14, 15 is
The transporting members such as the transporting rollers 16 for sandwiching and transporting the ticket are driven by the transporting motor M to transport the ticket guided therein. Further, a flapper f is provided at a branch position between the discharge conveyance path 14 and the collection conveyance path 15, and the ticket conveyed from the main conveyance path 11 is distributed to the ejection side or the collection side by the distribution function of the flapper f. Manipulate. The write head 12 is
The magnetic data of high coercive force, which is provided for writing the data for discriminating the bill type and which is specified for the discrimination, is written on the bill surface of the bill guided to the main transport path 11.

The reading head 13 is also provided to read the data for discriminating the type of bill, and reads the magnetic data of high coercive force that is specifically written for discrimination.

Tickets handled by this transportation system are tickets,
A ticket such as a coupon ticket or a commuter ticket is used, and the ticket is released or collected according to the discrimination data of the ticket type.

FIG. 2 shows a control circuit block diagram of the magnetic note type discriminating apparatus. The CPU 21 controls each circuit apparatus according to a program stored in the ROM 22, and the control data is readablely stored in the RAM 23.

Further, when discriminating the three types of bills, a high coercive bill which magnetizes magnetic data with a high coercive force on the bill face, a low coercive bill which magnetizes magnetic data on the bill face with a low coercive force, and a bill face The magnetic data is discriminated by reading three types, that is, a non-coercive non-coercive sheet, and the CPU 21 discriminates it from the data result of the sheet surface read by the reading head 13. This is Figure 3
As shown in, when read data and write data are found to match each other, it is determined to be a high coercive ticket A such as a commuter pass, and when read data and write data are not found to match each other, magnetic Low coercive ticket B such as a ticket with data
If there is no read data, it is determined to be a non-coercive ticket C such as a white ticket with no magnetic data.

The processing operation of the magnetic note type discriminating apparatus configured as described above will be described with reference to the flowchart of FIG.
Now, when discriminating the ticket type of the ticket inserted into the ticket insertion slot, the inserted ticket is guided to the position of the writing head 12 of the main transport path 11, where the magnetic data of high coercive force is applied to the ticket surface. Is written, and then the written magnetic data of high coercive force is read by the read head 13 (step n1
˜n2), at this time, if the read data and the write data match among the read magnetic data, the read head 13 was able to accurately read the magnetic data with high coercive force. It is determined to be a magnetic ticket A (steps n3 to n6). If the read data and the write data do not match among the read magnetic data and the read head 13 cannot read the magnetic data having a high coercive force and it is unclear to read, it is determined as a low magnetic coercive sheet B. (Step n7). Further, when there is no read data at the time of checking the comparison between the read data and the write data, the CPU 21 determines that it is a blank non-coercive sheet C which cannot be magnetically recorded (step n8). Then, the discriminated ticket is distributed to either the discharge conveyance path 14 side or the collection conveyance path 15 side according to the ticket type, and is conveyed to a predetermined position.

As described above, the magnetic data of the high coercive force is recorded on the face of the bill at the time of discriminating the bill type, and only by reading and judging the magnetic data, the high coercive ticket, the low coercive ticket and the non-coercive ticket can be selected. Either can be accurately determined. In particular, even a non-coercive sheet of blank paper can be accurately discriminated without being affected by a demagnetized sheet having the magnetic layer peeled off, and a highly reliable and stable discrimination process can be performed. Further, since it is not necessary to determine the magnetic output level, the determination circuit can be omitted, and the note type determination structure can be simplified and the cost can be reduced.
