[0002] Conventionally, magnetic recording medium processing instrumentation for the automatic ticket gate
While a magnetic recording medium (hereinafter, referred to as a magnetic card) such as an ordinary ticket or a commuter pass is conveyed along a conveyance path, data written on the magnetic card is read by a read head, and the read data is read. The data is used for arithmetic processing. [0003] In an automatic ticket gate, the above read data is used for arithmetic processing for an automatic ticket gate. And
New data resulting from the arithmetic processing, that is, entry / exit data, is written to the magnetic card via the write head, and then verified to check whether the write data is correctly written. It is configured to be read by the head. In writing data by the write head, the leading end position of the magnetic card (the end position of the magnetic card on the side in the carrying direction) of the magnetic card by the carrying path is set so as to be written at a predetermined position on the magnetic card. And the drive of the write head is controlled based on the detection signal. However, in the above-described conventional magnetic recording medium processing apparatus for an automatic ticket gate , the data write position on the magnetic card is controlled by detecting the leading edge position of the magnetic card by a sensor. since the way, driving when the start of the automatic ticket gate <br/>, the write head position must be initially adjusted for each automatic ticket gate, furthermore, the writing when the write head or sensor maintenance When the head or the sensor is replaced or moved, there is an inconvenience that the readjustment is required. The present invention has been made in order to solve the above-mentioned drawbacks, and an object of the present invention is to provide an automatic ticket gate that can easily perform initial adjustment or readjustment of a writing head.
To provide a magnetic recording medium processing device for a machine . [0007] An automatic ticket gate according to the present invention.

Control means for controlling the write timing of the head. [0008] [action] In the above configuration, the control means, to determine the write timing of the resulting writing head by comparing the synchronizing clock data stored in advance and the synchronous clock data read by the verify head The write timing of the write head is controlled based on the write timing. Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram of an embodiment of the apparatus. In a transport path 1 formed by pairing a pair of endless belts, a reading head is sequentially arranged from the upstream side to the downstream side of the transport path 1. H1, a write head H2 and a verify head H3 are provided. In the figure, M is a motor,
Is provided to drive. When a sensor (not shown) provided on the right side of the transport path 1 detects the magnetic card C, the motor M takes the magnetic card C into the transport path 1 by a drive signal from the controller 2, and further, The heads H1 to H3 are configured to be conveyed in the directions. In FIG. 1, reference symbol S denotes a sensor comprising a photoelectric element, which is provided between the reading head H1 and the writing head H2 so as to detect the position of the leading end of the magnetic card C conveyed on the conveyance path 1. Is provided. The controller 2 is composed mainly of a microcomputer, is connected to each of the heads H1 to H3, the motor M and the sensor S, and is configured so as to be able to control the apparatus of this embodiment as a whole. together and is configured to also control the main body of the automatic ticket gate. FIG. 2 is a front view of the magnetic card C,
A data recording section C 'is provided so as to be parallel to the transport direction of the magnetic card C. This data recording section C 'is provided with synchronous clock data C'1 and C'2 on both sides similarly to a known magnetic card, and the preamble data C' is provided inside one synchronous clock data recording section C'1. Three
However, a postamble data part C'4 is provided inside the other synchronous clock data part. And
Basic data C'5 is recorded between both amble data parts C'3 and C'4. Therefore, when the magnetic card C is conveyed along the conveyance path 1 in the direction of the arrow in FIG. 2, the read head H1 reads the synchronous clock data, the preamble data, the data postamble data, and the synchronous clock data in this order to control. It is taken into the container 2 . When the magnetic card C is taken into the transport path 1 from the side opposite to the direction of the arrow in FIG. 2, it is read in the reverse order to the above and taken into the controller 2 . The controller 2 performs a predetermined calculation process based on the data obtained from the read head H1, for example, a calculation process of an automatic ticket gate process, and new data which is a calculation result of the calculation process, for example, entry and exit data. Is written via the write head H2 at the timing of writing by the sensor S. Next, it is checked whether or not the written data is correctly written by the verify head H3. By the way, the magnetic card C is
If the data to be written into the magnetic card C is not written according to a predetermined standard, a read error will occur when the magnetic card C is next inserted into the magnetic card processing device. Therefore, the magnetic card processing device must be adjusted so that write data is written within a predetermined standard before starting operation or when the write head H2 or the sensor S is replaced or moved. No. FIG. 3 shows a control operation for adjusting the write data in the apparatus of the present embodiment. This adjustment is performed when the write head H2 or the sensor S is maintained or inspected when it is shipped from a factory. Will be The adjustment at the factory is performed by using a test magnetic card in which new data is written after being read by the read head H1, and the adjustment after maintenance is automatically performed by the magnetic card inserted first. It is done on a regular basis. Of course, the above test magnetic card can be used even after the maintenance check. First, after the controller 2 is set to the pacing mode, a test magnetic card or a magnetic card (FIG.
Then, when card C is inserted (Yes at step 100).
Hereinafter, the step is referred to as S. ), The data is read by the read head H1 (S102). In the controller 2 , arithmetic processing is performed based on the read data (S104), and new data (write data) to be written into the data recording section C 'is generated. Write head H timed at S
2 (Yes in S106, S108). The data written via the write head H 2 is then read by the verify head H 3 and taken into the controller 2. Then, the synchronization clock stored in the controller 2 in advance is compared with the synchronization clock acquired this time. That is, if the bit length and bit density captured this time are within the predetermined ranges, the relationship between the sensor S and the write head H2 is determined to be normal, and the adjustment ends (S110,
S112 affirmation). However, when the currently acquired synchronous clock data is out of the predetermined range (No at S112), for example, when the bit length of the synchronous clock data is shorter than the predetermined length, the writing of the write head H2 is performed. The timing is adjusted earlier than the previous time, and rewriting (retry) is performed (S114,
S116). This retry is performed when the motor M rotates in the reverse direction to return the magnetic card C to the front of the sensor S1, that is, the tip of the magnetic card C is returned to the magnetic head H1 side of the sensor S. This retry is performed until the synchronous clock data falls within a predetermined range. As described above, the apparatus according to the present embodiment is characterized in that the initial adjustment performed before the start of operation or the readjustment at the time of maintenance and inspection can be automatically performed by software based on the read data. There is.
