Therefore, when the leading end of the card CA is inserted up to the contact portion between the take-in roller 16 and the first pinch roller 22, the card CA is conveyed in the direction of arrow A by these rollers 16 and 22. Here, if the front end is detected by the second sensor 27 after the rear end of the inserted card has passed through the first sensor 26, the defective card whose overall length is shorter than the regular card in the control unit 33. And the motor 11 is driven in the reverse direction, and the defective card is returned from the card insertion slot 9. Further, when the front end of the card is detected by the fourth sensor 29 while the rear end of the inserted card is detected by the first sensor 26, the control unit 33 is longer than the regular card. Is determined to be a long defective card, the motor 11 is driven in the reverse direction, and the defective card is returned from the card insertion slot 9.

It is conveyed in the B direction. In S2, when the third sensor 28 is turned on and the front end of the card CA passes through the third sensor 28, the third sensor 28 is turned off, and in S3, the timer 31 starts measuring time. In S4, when the second sensor 27 is in the ON state and the front end of the card CA passes through the second sensor 27, the second sensor 27 is turned OFF. In S5, the time measurement by the timer 31 is terminated. The measured card transport time X1 is stored in the control unit 33. In S6, based on the card conveyance time X1, the calculation unit 32 calculates the card conveyance speed from the time when the third sensor 28 is turned OFF to the time when the second sensor 27 is turned OFF. That is, the conveyance speed Y1 obtained from the card conveyance time X1 and the interval L1 between the third sensor 28 and the second sensor 27 is
Y1 (mm / S) = L1 / X1
Is calculated as

In S7, when a command for a front discharge command is output from the control unit 33, in S8, the distance Z1 from the second sensor 27 to a predetermined position to stop in the arrow B direction side and Y1 calculated in S6 On the basis of the calculation unit 32, the required transport time x1 until the card is stopped at a predetermined position,
x1 second = Z1 / Y1

  In S10, when the second sensor 27 is in the ON state, when the front end of the card CA passes through the second sensor 27 and the second sensor 27 is turned off, the timer 31 starts counting in S11. In S12, When x1 has elapsed, x1 is counted by the timer 31, and in S13, the control unit 33 controls to stop driving the DC motor 11. Accordingly, as shown in FIG. 1B, the card CA has a front end portion exposed by the take-in roller 16 and the first pinch roller 22 so that the rear end portion is exposed to the outside of the apparatus from the card insertion port 9. It is pinched. Here, when forgetting to remove the returned card CA for some reason, the control unit 33 controls the DC motor 11 to drive in the forward direction, and the card CA is taken into the card transport path 7. It is.

  As described above, the existing sensor for detecting the entire length of the card is used to stop the card at a predetermined position, so that the clock pulse can be applied to the motor for card conveyance without adding parts. Since it is not an expensive motor having a function to be generated but a relatively inexpensive DC motor, the manufacturing cost can be reduced. The card transport speed Y1 calculated for stopping at a predetermined position is based on the transport time between the third sensor 28 and the second sensor 27 immediately before the card is stopped, and the fourth sensor. Since the conveyance is started from the position 29 and is based on the conveyance speed between the third sensor 28 and the second sensor 27 at a stable speed at which no acceleration occurs, the accuracy of the card stop position is improved. .

5, when the front end of the card CB passes through the third sensor 28 from the third sensor 28 in the OFF state in S22, the third sensor 28 is turned on, and the timer 31 starts measuring time in S23. . In S24, when the fourth sensor 29 is in the OFF state and the front end of the card CB passes through the fourth sensor 29, the fourth sensor 29 is turned on. In S25, the time measurement by the timer 31 is terminated. The measured card transport time X2 is stored in the control unit 33. In S26, based on the card transport time X2, the calculation unit 32 calculates the card transport speed from the time when the third sensor 28 is turned on to the time when the fourth sensor 29 is turned on.

  In S29, the DC motor 11 is driven in the forward direction to transport the non-contact type card CB in the direction of arrow A. In S30, when the third sensor 28 is in the ON state, when the rear end of the card CA passes through the third sensor 28 and the third sensor 28 is turned off, the timer 31 starts counting in S31, and in S32 , X2 has elapsed, x2 is counted by the timer 31, and in S33, the control unit 33 controls the DC motor 11 to stop driving. Therefore, as shown in FIG. 4B, the non-contact type card CB has a front end exposed to the outside of the apparatus from the card discharge port 10 and a rear end at the discharge roller 20 and the second pinch roller 23. It is pinched by. Therefore, the data recorded at the front end exposed from the card discharge port 10 is processed in a non-contact state by the processing unit 41 of the non-contact processing means 42.

  Also in the second embodiment, the card transport speed Y2 is determined by the third sensor 28 and the fourth sensor 29, which are transported from the position of the card take-in roller 16 and become stable speeds where no acceleration occurs. Since it is based on the conveyance speed in between, the accuracy of the stop position of the card is improved. Further, when the specification of the non-contact processing means 41 that is detachably attached to the card transport device 1 changes and the position of the processing unit 41 is shifted in the direction of the arrow AB, based on the changed Z2, Since the stop position can be freely set, it is possible to cope with various second processing means.
