FIG. 3 is a flowchart showing an operation processing procedure in a main part of the card manufacturing apparatus. Therefore, FIG.
Next, the basic operation of the main part of the card manufacturing apparatus will be described with reference to the flowchart shown in FIG. First, the lower film FL and the upper film FU are fed from right to left in FIG. 1 and are superimposed at the position of the guide rollers 19 and 20 to form a laminated film 100. 101, that is, it is discharged by the driving guide roller 30 and the driven guide roller 31 rotated at the reference speed by the reference speed motor 34. On the other hand, the pitch feed motor 35 in the second feed means 102 is stopped at the beginning. Accordingly, as the laminated film 100 is fed by the driving guide roller 30 and the driven guide roller 31, the loop amount of the lower film FL in the portion where the free hole 33 is hanging decreases, and the free hole 33 is moved from the lower side. The sensor unit 39c of the free hole detection sensor 39 is turned off and turned off. Then, the free hole 33 reaches the position shown in FIG.
Is moved upward, the sensor unit 39b is turned on (step S1).

When the sensor unit 39b is turned on, the control unit 45
Then, the signal is detected, and the pitch feed motor 35 is started via the driver 50 (step S2). Then, the feed roller 12 rotates integrally with the pitch feed motor 35, and is located upstream of the feed roller 12 (right side in FIG. 1).
Of the lower film FL located on the downstream side (left side in FIG. 1)
Sent out to. The feeding amount at this time is larger than the feeding amount of the lower film FL by the driving guide roller 30 and the driven guide roller 31. Therefore, when the feeding of the lower film FL by the feed roller 12 is started, the free holes 33 are moved from the upper side to the lower side.

A black mark 42 is provided on the lower film FL at a constant pitch.
When 2 is detected by the mark detection sensor 38, the control unit 45 interrupts the pitch feed motor 35 by interruption (steps S3 and S4). The position of the free hole 33 when this stop is applied is the position shown in FIG.

Thereafter, the board attaching unit 36 is driven to attach the flexible printed board onto the stopped lower film FL (step S5). During the sticking operation of the flexible printed board by the board sticking unit 36, it is necessary to stop the flow of the lower film FL, and the drive guide roller 30 and the driven guide roller 31 driven by the reference speed motor 34 are required.
Of the lower film FL by the free hole 33
Is absorbed by moving from the lower side to the upper side, and does not affect the attaching operation of the flexible printed circuit board. That is, the attaching operation of the flexible printed circuit board is performed within the distance (L2-L1) shown in FIG. The time for which the free hole 33 moves the distance (L2−L1) is set by controlling the rotation speed of the reference speed motor 34 via the driver 49.

Thus, one cycle of the operation of attaching the flexible printed circuit board to the lower film FL is completed. Thereafter, the process returns to step S1 again, and the same operation is repeatedly performed.

The lower film FL, which has been fed with the flexible printed circuit board attached thereto, is coated with an adhesive on the upper surface at the coating dispenser 40, and further, the upper film FU is positioned at the guide rollers 19, 20.
Are superimposed. Then, the lower film FL and the upper film FU are overlapped to form a single laminated film 100, which is discharged to the PET processing unit 3 side at a reference speed. After that, it is cut into a predetermined size in the PET processing unit 3 to produce an IC card of a required size.

Therefore, according to the structure of this embodiment, the continuous feed operation by the first feed means 101 comprising the reference speed motor 34, the drive guide roller 30 and the driven guide roller 31 is performed by the intermediate free hole 33 and the loop. When the work of attaching the flexible printed circuit board is performed, the feed by the second feed means 102 including the pitch feed motor 35 and the feed roller 12 is stopped, and the flexible printed circuit board is stopped during the stop. Work of pasting can be performed. This simplifies the structure of transporting the film (band-like material), and at the same time simplifies the control system and simplifies software design. Also,
By simplifying the control system, it is possible to reduce the time required to start up the system.
