2. Description of the Related Art Conventionally, this type of magnetic stripe read
As shown in FIG. 2, the writing apparatus includes a main processing section 1, an editing processing section 2 for data used for transmission and reception, a control circuit 3 for controlling the apparatus, and a magnetic stripe 13 bonded to a passbook 14.
A magnetic head 8 for reading and writing data to the head, an actuator 5 for driving a read screw 7, and a read screw 7 for moving the magnetic head 8 by rotating.
, A shaft 6 for supporting the magnetic head, and a slit disk 12 fixed to the lead screw 7.

The control circuit 3 drives the actuator 5 and rotates the magnetic head 8 by rotating the lead screw 7, while the control circuit 3 controls the magnetic stripe 13 adhered to the passbook 14 through the magnetic head 8. Read and write data. With this operation, the magnetic head
The data edited by the editing processing unit 2 is written on the magnetic stripe 13 in synchronization with a signal generated in the sensor 11 by the rotation of the slit disk. The normal operation of the magnetic head 8 is to read the magnetic data of the magnetic stripe 13 and edit the magnetic data by the edit processing unit 2. That is, the slit disk 1
The recording density on the magnetic stripe 13 was fixed by the slit interval of 2.

[0004]

In this conventional magnetic stripe read / write device, the device is designed to a standard of a magnetic stripe having one recording density. -There was a problem that writing was not possible. In addition, it is necessary to provide different editing processes for devices having different recording densities.

SUMMARY OF THE INVENTION A magnetic stripe read / write device according to the present invention includes a magnetic stripe read / write head for reading / writing data from / to a magnetic stripe, and a magnetic stripe read / write head that supports the magnetic stripe. A lead screw that moves the magnetic stripe read / write head by rotating, a slit disk fixed to the read screw, a sensor that sandwiches the slit disk that outputs a pulse according to its rotation, and a sensor for the lead screw. A counter circuit for counting pulses generated from the sensor according to the rotation, a storage density of the magnetic stripe determined by the counter value, and a data format of the magnetic stripe.
And a plurality of editing processing units that are selected according to the read configuration and handle read / write data.

[0006]

Next, the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram showing the configuration of one embodiment of the present invention.

The actuator 5 receiving the command from the control circuit 3 transmits the drive transmitted by the pulley belt to the lead screw 7. As the lead screw 7 rotates, the magnetic stripe read / write head 8 (sometimes abbreviated as “MS head”) starts to move in a designated direction while being supported by the shaft 6. When the magnetic stripe read / write head 8 blocks light at the sensors 9 and 10, the control circuit 3 performs control to reverse the rotation direction of the actuator. During this operation, the magnetic stripe 1
3 is written or read.

When writing on the magnetic stripe 13,
A, A in the editing processing unit 2 designated by the main processing unit 1
One of the editing processing units B and C is selected. Each editing unit handles different types of recording configurations and data conversion. Further, according to the designation of the main processing unit 1, the write data processed by the selected editing processing unit is generated from the magnetic stripe read / write head 8 operated by the control circuit 3 by the sensor 11 due to the rotation of the slit disk 12. The counter circuit 4 counts the clock. Based on the output (counter value) of the counter circuit 4, the magnetic stripe 13 is written at a required timing. For example, 100 BP for a recording density of 200 BPI
In the case of realizing I, writing may be performed at every double count (every two pulses) with respect to the count value of 200 BPI.

Next, when data is read from the magnetic stripe 13, magnetic data on the magnetic stripe is read from the magnetic stripe read / write head 8 operated by the control circuit 3 in accordance with an instruction from the main processing unit 1.

At this time, the recording density is determined by counting the clock generated by the sensor 11 due to the rotation of the slit disk 12 with respect to the changing waveform. Further, the editing processing unit determines which type is used and performs processing. Further, in the case of reading, the main processing unit 1 can read by selecting the editing processing unit to be used, similarly to the case of writing, without using the counter circuit 4 as in the related art.

[0011]

As described above, the present invention treats the amount of movement of the magnetic head as a counter circuit for counting pulses from the slits of the slit disk, and uses the counter value as a reference for recording density to handle read / write data. The provision of the edit processing unit has an effect that the same device can read / write data to standards having different recording densities.
