Abstract

PURPOSE:To control a card driving by a few card position detectors without providing a position detecting mark for a driving control by inverting a card driving direction by the output signal of the specific detector, at the time of a card back-and-forth driving after the stoppage of a card insertion. CONSTITUTION:At the time of moving an optical card 1 back and forth one time when an edge ID area is positioned at a reading head 10m at the first, the output signal of a photo reflector (CIN) 600 is a High state, and the output signal of a photo interrupter (PIR) 601 is the High state. Then, when the card 1 is carried in one way by a driving roller 3, and a center ID area is positioned at the head 10, the output signal of the CIN 600 is changed from the High state to a Low state. According to the change, a driving inversion position is detected, and the driving direction of the roller 3 is inverted. When the edge ID area reaches the head 10 again, the output signal of the PIR 601 is changed from the Low state to the High state, and the completion of the one way driving is detected.

Similarly, each of the other upper rollers 53 to 56 is also configured such that each rotation shaft is movably engaged with a notch groove formed in the frame 2 in a vertically displaceable manner. However, unlike the upper rollers 51 and 52, the upper rollers 53 to 56 do not have the driving roller 3 below them, so that the entrance portion of the notch groove is formed of a suitable member such as a leaf spring in order to prevent the upper roller from falling. Close it up. Further, the frame is provided with pressing springs 61 to 64 in contact with the lower surface of the optical card 1, so that the upper surface of the optical card 1 can effectively contact the upper rollers 51 to 56. These pressing springs 6
The optical card 1 is urged upward by the drive rollers 3 to 1 to 64 and the drive roller 3 described above.

A photo reflector 600 (hereinafter referred to as a card-in sensor CIN) for detecting the insertion of an optical card is arranged in the vicinity of the entrance hole 2a of the frame 2, and an optical card is provided at the rear end of the frame 2. A photo interrupter 601 (hereinafter, referred to as a photo interrupter PIR) that detects the transport stop position of is disposed. This CIN600
Outputs a High signal when there is no optical card 1 and outputs a Low signal when there is an optical card 1. Also, P
The IR 601 outputs a Low signal when there is no optical card 1 and outputs a High signal when there is an optical card 1.

The positional relationship between the two optical sensors is such that, when the edge ID area 5 of the optical card 1 is at the position of CIN 600, when the optical card 1 is moved in the insertion direction by a half of the length of the optical card. The PIR 601 is placed at a position where the tip of the card 1 is detected. Both sensors can be positioned freely in the short side direction of the card.
Next, regarding the operation of the card drive device according to the present invention,
This will be described with reference to FIGS. 2 and 7.

When the optical card 1 is inserted into the frame 2,
Card insertion is detected based on the output of CIN600,
The optical card 1 includes a read head 1 as shown in FIG.
It is conveyed until the edge ID area 5 is located at the reading position of 0. For stopping the transportation of the optical card 1, see P.
This is performed by the signal output of IR601. FIG. 2 shows a state in which the optical card 1 is inserted into the frame 2 and the transportation is stopped.

The above operation will be described in more detail with reference to FIG. This figure shows a carrier control signal associated with the insertion of an optical card, where the length of the optical card 1 is a and the half length thereof is b.

Before inserting the optical card 1 into the frame 2, the output signal of the CIN 600 is High before insertion.
Although the output signals of the h and PIR 601 are in the Low state, when the card end reaches the CIN 600, the output signal of the CIN 600 changes from High to Low (insertion detection). Based on the signal change of the CIN 600, the optical card 1 is carried into the frame by a carrier mechanism (not shown). Further, in accordance with this insertion detection, the drive roller 3 is driven via the control means and drive means (not shown).
When the optical card 1 is conveyed to the inside of the frame by the conveying mechanism and reaches the driving roller 3, thereafter, the card is automatically fed into the inside of the apparatus.

When the optical card 1 is conveyed by a (length of the optical card 1) from the insertion position, the output signal of the CIN 600 changes from Low to High, but the drive roller 3 remains driven. And the optical card edge is PIR6
When it reaches 01, the output signal of the PIR 601 changes from Low to High (stop position detection). This PIR60
Based on the signal change of 1, the driving of the driving roller 3 is stopped and the loading is completed.

After the card has been inserted and conveyed, the reading head 10 moves in the width direction of the optical card 1 to seek a desired track in the edge ID area 5. The reading position of the reading head 10 is the center ID area 4
The optical card 1 is moved until it is positioned at, and the data in the data area 7 is read. After that, this operation is repeated. That is, the optical card 1 is reciprocally driven between the center ID area and the edge ID area. When reading the data in the data area 8, the optical card 1 is reversed and inserted into the frame 2. The above operation will be described in more detail with reference to FIG. This figure shows a carrier control signal in the reciprocating drive of the optical card 1.

For example, a case where the optical card is reciprocated once from the state where the edge ID area 5 is located at the read head 10 will be described. Initially, the output signal of the CIN 600 is High and the output signal of the PIR 601 is High. When the optical card 1 is conveyed one way by the drive roller 3 and the center ID area 4 is located at the read head 10, the output signal of the CIN 600 is High.
Change from h to Low. The drive reversal position is detected by this change, and the drive direction of the drive roller 3 is reversed based on this detection signal. After that, when the edge ID area 5 reaches the position of the read head 10 again, the output signal of the PIR 601 changes from Low to High. This change detects the completion of one reciprocating drive.

Similarly, the case where the optical card is reciprocated once when the center ID area 4 is located at the read head 10 will be described. Initially, the output signal of the CIN 600 is low, and the output signal of the PIR 601 is low. Then, when the optical card 1 is conveyed one way by the drive roller 3 and the edge ID area 5 reaches the position of the read head 10, the output signal of the PIR 601 is Lo.
Change from w to High. The drive inversion position is detected by this change, and the drive roller 3 is detected based on this detection signal.
Reverse the driving direction of. After that, when the center ID area 4 reaches the position of the read head 10 again, the output signal of the CIN 600 changes from High to Low. This change detects the completion of one reciprocating drive.

As described above, in the present invention, since both ends of the optical card are detected, the number of optical sensors can be reduced as compared with the conventional one. In the drawings, a drive circuit and a control circuit for driving and controlling the drive roller 3 are omitted.

Although an optical card is used as an embodiment of the present invention, the present invention is not limited to this. For example, an optical card having one data area on one surface, a magnetic card or It can be effectively applied to various card driving devices such as IC cards.

[0031]

According to the card driving device of the present invention, it is not necessary to provide a position detection mark on the card when driving the card, and therefore the card manufacturing process is facilitated. Also, along with this, the drive control of the card is
It will not be affected by scratches.

Further, since the card drive is controlled by detecting the edge of the card, the number of sensors for detecting the card can be reduced. As a result, the cost is reduced by reducing the number of parts.
