Description

[Detailed description of the invention]

The present invention relates to a magnetic card reading device that is capable of re-reading magnetic information in a reversing process in the event of a reading failure when reading magnetic information on a magnetic card including a voting ticket or the like. Conventionally, voting information such as race name, group number, and amount is magnetically written on the back of voting tickets sold for horse racing, etc., and this is read by a magnetic head in the same way as a normal magnetic card, and the voting information is used as a winning ticket. A payout device is used that queries a higher-level device to determine whether or not the ticket is a winning ticket and calculates the payout for winning tickets, displays the results, and automatically pays out cash. Conventional voting tickets are inserted into the insertion slot by operators and customers, and if the card cannot be read magnetically, the motor for transporting the card is reversed, the voting ticket is returned to the insertion slot, and a display, buzzer, etc. I was letting you know. When the operator and the customer learn that the voting ticket has been read incorrectly, they repeat the process of inserting the voting ticket into the insertion slot again. In this method, the voting ticket is returned to the operator and customer every time there is a reading failure, which increases the time required to process the refund of one voting ticket, and also causes trouble for the operator and customer due to reading failure caused by the machine. This will give a bad impression. On the other hand, in the case of a reading failure, instead of returning the voting ticket to the operator and the customer, there is a method in which the voting ticket is returned to the insertion slot and the motor is automatically reversed to reread it. In this case, the labor of the operator and customer can be saved, but it is obvious that the efficiency is low because even though the voting ticket passes over the magnetic head when the voting ticket is returned, it is not read. SUMMARY OF THE INVENTION An object of the present invention is to provide a magnetic card reading device that efficiently rereads the magnetic card of a voting ticket when the reading fails. In order to achieve the above object, the magnetic card reading device of the present invention comprises: a magnetic card provided with a start code and an end code respectively before and after predetermined information; a conveying means for conveying the magnetic card in forward and reverse directions; a reading means for detecting either a start code or an end code of a card and detecting predetermined information each time the magnetic card passes; and reversing the reading order of the predetermined information according to the detection result of the start code or end code. and a means for determining a read result of the predetermined information, and if the determination result of the determination means indicates that the predetermined information cannot be read, the conveyance direction of the conveyance means is reversed. The present invention will be described in detail below with reference to examples. FIG. 1 shows an example of the format of magnetic information recorded on the back side of a voting ticket used in the present invention. In the figure, a start code (SC) 4 and an end code (EC) 5 are provided before and after six lines of voting information 3 on a voting ticket 2 corresponding to a six-channel magnetic head 1. The bits corresponding to these six channels are weighted bits 1 (2 ⁰ ), 2 (2 ¹ ) of 2 bits each with clock timing C in between.
, 4 ( ² ), 8 ( 2 ³ ), and parity P. When the voting ticket 2 is inserted from one side of the card conveying section and this SC4 or EC5 is detected by the magnetic head 1 provided in the middle, the voting ticket 2 is immediately inserted by identifying the magnetic data when the head starts reading.
The initial insertion direction and the subsequent transport direction can be identified. If the weighted codes shown in Figure 1 are set in SC4 and EC5 of voting ticket 2, voting ticket 2
When the insertion direction is positive, that is, when SC is in front,
In the opposite direction, that is, when EC is in the previous case, the bit position corresponding to the weighted bit changes, so a different code is detected, and SC and EC are detected reciprocally, corresponding to the forward and reverse directions of transport. Therefore, a different code is detected, and this code is expressed in hexadecimal as shown in Table 1.

[Table] As shown in the table above, the processing procedure for voting information 3 is different by identifying whether the insertion direction of the voting ticket 2 is forward or backward using the magnetic head, and whether it is forward or reverse in each case. It's coming. Table 2 shows this processing procedure.

[Table] With such a configuration and procedure, conventionally, in the case of a read failure, only the forward direction was repeated several times, but in the present invention, detection in the reverse process can be used, making it possible to shorten the processing time. A further advantage is that even if there is a reading failure in the forward direction, reading in the reverse direction is often possible. Although this has not received much attention in the past, the method of the present invention can significantly reduce the incidence of reading failures due to causes on the machine side. FIG. 2 is an explanatory diagram showing the structure of an embodiment of the present invention, and shows an example of a payout device for a winning ticket for the voting ticket shown in FIG. 1. In the same figure, a voting ticket 2 is inserted in an arbitrary direction by the six-channel reading head 1 illustrated in FIG.
is inserted. First, when the SC or EC at the start of reading is read out, the data of the 6 channels is amplified by the amplifier 11 and compared with the reference signal of SC or EC by the comparator 12 to determine whether the insertion direction is positive or negative, and the channel is switched. A circuit 13 switches the channel depending on the forward direction or reverse direction. That is, according to Table 2, in the case of reverse direction, the channels are switched in the order starting from the last address, input to the magnetic reading control section 14, voting information is checked, and if there is no reading error, the information is transferred via the main control section 15. The winning information is sent to a processing unit (CPU), checked against hit information, and the payout amount is returned and displayed on the display unit 16. As a result, the cash is released, and as will be described later, the voting ticket is conveyed by inputting a conveyance control photo signal to the conveyance control section 17, outputting a solenoid control signal and a motor drive signal, and passing it through the ticket punch 31. It falls into the ticket stack. Next, if the reading of the voting information is poor as a result of the check in the magnetic reading control section 14, the voting ticket 2 is transferred to the transportation control section 1, as will be described in detail later in FIG.
7 inputs a photo signal for conveyance control, outputs a solenoid drive signal and a motor drive signal, reverses the conveyance direction, and causes the magnetic head to read again.
At the same time, the magnetic reading control section 14 sends a switching signal to the channel switching circuit 13 to switch the channel in preparation for rereading by the magnetic head in the reversal process. The re-reading results are also sent to the magnetic reading control unit 1.
4, and if there is a reading failure, the card is further reversed at the end of the card transport section and the same procedure as above is repeated. FIG. 3 is an explanatory diagram of a specific configuration of a magnetic reading section related to the embodiment of FIG. 1. In the same figure, the card transport section is connected to the reading head 1.
It consists of an endless belt 20 that passes between the rollers 25, 26 and the drive roller 28, and is stretched between the rollers 25, 26 and the drive roller 28, and the voting ticket 2 is passed in the forward direction (right → left) or in the reverse direction (left → right). It is then transferred by the drive motor 27. An insertion slot for the voting ticket 2 is provided in the shutter 29 after the roller 25, and photo sensors 21 and 22 are arranged on both sides of the shutter 29.
A stopper 30 and a ticket punch 31 are provided in front of the machine, and a photo sensor 23 is arranged between them. Now, when the tip of the voting ticket 2 is detected by the photosensor 21, the shutter 29 is opened and the voting ticket 2 is transported in the forward direction by the drive motor 27, the magnetic information of the voting ticket 2 is read by the reading head 1, and the photosensor 22 detects that it is not detected. When the weather gets cold, the shutter 29 closes. The result detected by the reading head 1 is checked by the magnetic reading control unit 14 shown in FIG.
Open the 0 and it will fall into the ticket stacker. On the other hand, if the check shows that the reading is defective, the tip of the voting ticket 2 hits the stopper 30 and the photosensor 23 detects the ticket, the drive motor 27 is reversed, and during this reversal process, the reading head 1 performs rereading. . The re-reading procedure is carried out as described above, and if reading failure continues, the photosensor 22 and shutter 29
The voting ticket 2 is reversed by , and this process is repeated. As described above, according to the present invention, when reading the magnetic information of a magnetic card including a voting ticket or the like, if there is a reading failure, the magnetic information can be reread during the reversal process. This can shorten the processing time in the case of a reading failure, and can also be expected to improve the reading rate since reading in the reversal process is often better in identifying readings than conventional reading in the forward direction only. In this embodiment, by providing information that identifies the insertion direction and conveyance direction of the ticket before and after the magnetic information of the voting ticket, it is possible to easily read and judge the information content, but this is not a necessary condition, and other Equivalent functions may be provided depending on the method.
