In devices that read magnetic recording tickets, in which data is magnetically recorded on the back side of tickets, voting tickets, etc., that is, the magnetic recording surface coated with magnetic material, when the back side of the magnetic recording ticket is read with the back side facing upward, the magnetic head is located below the magnetic recording ticket, so there is a gap between the magnetic recording surface and the magnetic head corresponding to the thickness of the ticket. Therefore, the force of the magnetic flux that reads the magnetic recording surface also becomes weaker. Therefore, when reading in this state, if no signal is output from the magnetic head, it can be determined that the magnetic recording surface is facing upward. However, in reality, some of the magnetic recording signals on the upper magnetic recording surface may be detected by the magnetic head due to the thickness of the magnetic recording ticket. At this time, the detection signal of the magnetic head becomes confusing in case of a reading failure. For this reason, conventionally, it has not been possible to determine whether the magnetic recording ticket was inserted with its back side facing up, or whether the magnetic recording surface of the ticket was not read properly even though the back side was facing down. In view of the above problems, the present invention provides a front/back determination circuit for a magnetic recording ticket that can accurately determine whether the front side of the magnetic recording ticket is placed on the lower side or not. The purpose is to

The present invention uses a magnetic head provided separately from a magnetic head for reading normal data to perform read synchronization from the recording surface of a read synchronization clock provided side by side with a magnetic recording surface on which normal data is recorded. Detects clocks and counts the number of clocks. This number of clocks is then compared with a predetermined threshold. This threshold value is set to a value that allows determination of whether the magnetic recording surface is front or back.

When the number of clocks of the read synchronization clock is equal to or greater than a predetermined threshold, it is determined that the magnetic recording surface of the magnetic recording ticket is facing the magnetic head side, and if the data read from the magnetic recording surface is defective at that time, the magnetic recording data is It can be determined that the product itself is defective. Further, when the number of clocks of the read synchronization clock is less than or equal to a predetermined threshold value, it is determined that the magnetic recording surface of the magnetic recording ticket is facing upward.

As shown in FIG. 3, the magnetic recording ticket 1 has a back side 1-1 that constitutes a magnetic recording surface coated with a magnetic material, a paper 1-2, and a front side 1- that is printed on the front side of the paper.
It consists of 3.

磁気ヘツドへの出力信号は大となる。 When the surface 1-3 of the magnetic recording ticket is brought into contact with the magnetic head, the magnetic recording surface moves away from the magnetic head by the thickness of the magnetic recording ticket 1, so that the force of the magnetic velocity read by the magnetic head becomes weaker. On the other hand, when the back side 1-1 of the magnetic recording ticket 1 is brought into contact with the magnetic head, the output signal to the magnetic head becomes large.

する。 As shown in FIG. 1, a magnetic head 2-1 for detecting magnetically recorded contents is brought into contact with the lower side of the magnetic recording ticket 1, and an amplifier 3-1 amplifies the output signal of the magnetic head.
The output signal from the magnetic recording ticket 1 is decoded by the decoder 4. The output of the decoder 4 is sent to the MPU, where the magnetically recorded data is analyzed. Next, a read synchronization clock recorded adjacent to the magnetic recording surface is detected by a read synchronization clock magnetic head 2-2, amplified by an amplifier 3-2, and then input to a decoder 4. Here, the read synchronization clock is used to set the timing for reading data from the magnetic recording surface. Further, the output of the amplifier 3-2 is input to the counter 5, and the number of clocks of the read synchronization clock is detected. On the other hand, the threshold circuit 7 stores a threshold value of the number of clocks for determining whether the magnetic recording ticket 1 is front or back. Therefore, the output of the counter 5 and the output of the threshold value circuit 7 are compared by the comparator 6, and when the output of the counter 5 is greater than the threshold value 7, the back side 1 of the magnetic recording ticket 1 is
Since it is considered that -1 is in contact with the magnetic heads 2-2 and 2-1, the front and back sides of the magnetic recording ticket 1 are correct. Further, when the output of the counter 5 is smaller than the output of the threshold circuit 7, the output of the comparator 6 indicates that the surface 1-3 of the magnetic recording ticket 1 is lower than the magnetic head 2-3.
1 and 2-2. Therefore, if the contents recorded on the magnetic recording ticket 1 cannot be read normally, the output of the threshold circuit 7 and the counter 5 corresponding to the number of read synchronization clocks are compared, and if the output of the counter 5 is large, the magnetic recording is completed. Since the back of the ticket is correctly placed on the magnetic head side, it is found that the data on the magnetic recording surface is defective. Conversely, when the output of the counter 5 is smaller than the output of the threshold circuit 7, it means that the front side 1-3 of the magnetic recording ticket is on the lower side and is in contact with the magnetic head, so the front and back sides are I judge it to be the opposite.

る。 FIG. 2 shows the correspondence between the count number of the read synchronization clock of the magnetic recording ticket and the number of magnetic recording tickets 1 that generate the relevant count number. When the count number of the synchronous clock of the magnetic recording ticket is close to the originally recorded number 80, it indicates that the back side 1-1 of the magnetic recording ticket 1 is placed downward, and the reading synchronous clock of the magnetic recording ticket 1 is When the count number is close to 0, it indicates that the surface of the magnetic recording ticket is placed on the lower side, that is, on the side of the magnetic head. In the threshold circuit 7 which provides threshold data for the number of synchronous clocks, it is possible to determine whether the magnetic recording ticket 1 is front or back by setting the number of synchronous clock counters at, for example, 20 to 40 as a threshold for determining whether the card is front or back. .

It is something.
