FIG. 4 is a concrete block diagram of the motor speed control circuit 45 shown in FIG. 3. Next, the configuration of the motor speed control circuit 45 will be explained with reference to FIG. Motor speed control circuit 45 includes a relay coil 451. This relay coil 451 closes a contact 452 and opens a contact 454 when the conveyor belt 21 is moved at high speed. And C
When a low speed command signal is given from PU49, contact 452
is opened and contact 454 is closed. Contact point 452 is relatively ^
A battery 453 that outputs a high reference voltage is connected to the contact 45.
4 is connected to a battery 455 that outputs a relatively low reference voltage. Then, when the contact 452 is closed, the voltage 145
3 is applied to the reference input of comparator 456, and when contact 454 is closed, a relatively low reference voltage from battery 455 is applied to the reference input of comparator 456. The tacho generator of the motor 22 outputs a pulse signal according to the rotational speed. This pulse signal is integrated by an integrating circuit consisting of a capacitor 458 and a resistor 457 via a diode 460 and a resistor 459.
It is applied to the comparison input terminal of comparator 456. Comparator 456 compares the integrated pulse signal from the tachogenerator with a reference voltage, outputs a corresponding analog voltage, and supplies it to motor drive circuit 461 . A forward command signal or a comfort command signal is given to this motor drive circuit 461 from the CPU 49. The motor 11 circuit 461 determines the direction of one rotation of the motor 22 according to the forward command signal or the one-turn command signal, and the comparator 456
The rotational speed of the motor 22 is determined according to the analog voltage output from the motor.

FIG. 5 is a diagram showing changes in the speed of the conveyor belt 21 of a conventional card writing/reading device with a printer, FIG. 6 is a diagram showing a speed chart according to an embodiment of the present invention, and FIG. FIG. 2 is a flowchart for explaining the specific operation of an embodiment of the present invention.

Next, the specific operation of one embodiment of the present invention will be described with reference to FIGS. 1 to 711. When the CPLJ 49 receives date information and time information from the clock circuit 48, it determines which printing area 11 of the card 1 corresponds to the date information. Then, the CPU 49 determines, based on the determined printing area, the 6th!
The number of pulses corresponding to jl) is calculated and stored in the register 52. In addition, the CPLI 49 similarly operates for 12 seconds from the position where the low speed command is output to the position where the stop command is output.
The number of pulses corresponding to the period (see FIG. 6) is calculated and stored in the register 53.

When the card 1 is inserted into an insertion slot (not shown), the card detector 28 detects the card 1. When the CPU 49 receives the card detection signal, it gives a high-speed advance command to the motor speed control circuit 45.

Relay contact 452 then closes and a relatively high reference voltage is applied to comparator 456.

At this time, a pulse signal corresponding to the rotational speed of the motor 22 is output from the tacho generator. This pulse signal is passed through a diode 460 and a resistor 459 to a resistor 457.
and a capacitor 458. Comparator 456 deposits the reference voltage and the integrated pulse voltage and provides a relatively high analog voltage to motor drive a11461. Since a forward command is given to this motor drive circuit 461, the motor 22 rotates at high speed. The rotational force of the motor 22 is transmitted to the roller 24 via the belt 23. As a result, the conveyor belt 21 is moved toward the printer 3 side, and therefore, the card 1 is transferred by the conveyor belt 21 at a true speed.

When the card 1 reaches the position of the magnetic head 27, the write/read control circuit 46 causes the magnetic head 27 to move the card 1 based on the date information and time information output from the clock circuit 48.
magnetic recording area 1 for writing data in the magnetic recording area 12 of
The card 1 with data written on it is further transferred to the conveyor belt 2.
1, it is moved to the printer 3 side. At this time,
The CPU 49 determines whether or not the detection signal of the printing origin detector 29 is input. When the printing origin detection 29 detects the card 1, the counter 51 counts the pulse signal output from the pulse generator 1131. And C
The PU 49 compares the count value of the counter 51 and the number of pulses stored in the register 52, and if they match, outputs a low speed command. That is, the CPLI 49 outputs the low speed command slowly after the print origin detector 29 detects the card 1.

When a low connection command is output from the CPU 49, relay contact 4
52 is opened and relay contact 454 is closed. Then, a relatively low reference voltage is input to the comparator 456 from the battery 455 . The comparator 456 determines that the voltage obtained by integrating the pulse signal output from the tacho generator is higher than the reference voltage, and then applies a relatively low analog voltage to the motor drive circuit 461. Therefore, the motor drive circuit 461 causes the motor 22 to rotate at a low speed. Then, the counter 51 counts the pulse signals from the pulse generation 1131 of the number corresponding to the T2 period shown in FIG. When the number of pulses matches the number of pulses stored in the register 53, the CPU 49 determines that the low-speed feed has been completed and outputs a stop command. That is, both the forward command and the pass command are no longer given to the motor drive circuit 461. Then, motor drive @m46
1 stops the energization of the motor 22. However, motor 2
Even if the energization of the motor 2 is stopped, the motor 22 does not stop instantaneously and rotates by inertia during the T3 period shown in FIG. Therefore, if the 1st period and 12th period are set so that the determined print area of the card 1 reaches directly below the print head 34 of the printer 3 during the period T3 when the paper roll rotates by inertia, The card 1 can be stopped at a predetermined printing position extremely accurately.

When the card 1 is stopped, the print head 34 is activated by the clock circuit 48.
The date information and time information output from the printer are printed in a predetermined printing area. When printing is completed, the CPU 49 issues a high-speed advance command. Then, the relay contact 452 is opened and the relay contact 454 is closed, and a general command is given to the motor drive circuit 461. As a result, the direction of rotation of the motor 22 is reversed, and the motor 22 rotates once at high speed. Then, the conveyor belt 21 also rotates in the opposite direction, and the card 1 retreats at true speed.

As described above, in this embodiment, after the print origin detector 29 detects the card 1, the motor 22 is rotated once at low speed in the 11th period, and the energization of the motor 22 is stopped after the 2nd period has passed. Therefore, the period during which the motor 22 rotates due to inertia can be shortened. However, in the conventional card writing/reading device with a printer, as shown in FIG. 22 is de-energized, which lengthens the inertial rotation period (T5) of the motor 22, making it difficult to accurately stop the predetermined printing area of the card 1 at the printing position of the printer 3. Ta. However, in this embodiment, as mentioned above, the drawbacks of the conventional technology can be sufficiently overcome.

In the above-described embodiment, the data is written in the magnetic recording area 12 by the magnetic head 27, and the data is printed in the printing area 11 by the printer 3. However, the present invention is not limited to this. The present invention can also be applied to a card loading/reading device with a printer that prints data in the printing area 11 with the printer 3 after reading the data.

As described above, according to the present invention, the writing/reading means performs at least one of writing and reading data, detects the distance until the recording medium reaches a predetermined printing position, and detects the distance until the recording medium reaches a predetermined printing position. Since the transport speed of the recording medium is reduced in response to the detection output, even if the transport of the recording medium is stopped, the transport distance due to inertia can be reduced, so the recording medium can be transported extremely accurately. It can be stopped at the printing position.
