Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention is a card or the like that incorporates a semiconductor integrated circuit (IC) and transfers information between the IC card and the IC card that holds storage and calculation functions. The present invention relates to an IC card leak writer, and particularly relates to a detection device for detecting that an IC card is placed at an appropriate position within the IC card leak writer.

[Prior Art] An IC card leak writer is an IC card leak writer that incorporates a semiconductor integrated circuit (IC) into a card, etc., stores an IC card with storage and calculation functions in a card holder, and exchanges information with the IC card. I know. Such an IC card leak writer uses a detection device that detects whether the IC card is placed at an appropriate position within the card holder.

The conventional detection device includes a card holder with a movable board that moves horizontally at a predetermined height position when an IC card is inserted.
Due to horizontal movement, the lower surface of the moving board comes into contact with a lever-type switch and presses the switch. When this switch is set at a predetermined angle, it is determined that the IC card is placed in the appropriate position in the card holder, and the switch is released. The detection signal is configured to be output.

In addition, a light emitting element and a light receiving element constituting an optical coupling circuit are arranged, and the light from the light emitting element is reflected by the moving board that moves horizontally, and when this reflected light is received by the light receiving element, the IC card is inserted into the card holder. Some devices use a reflective photointerrupter that is configured to output a detection signal from a switch when it determines that it has been placed in an appropriate position.

[Problems to be Solved by the Invention] However, in any configuration, the conventional detection device has a lever-type switch that cannot be activated when the height of the moving board changes even if the IC card is placed in the appropriate position within the card holder. is not set at a predetermined angle, and even if a reflective photointerrupter is used, if the height of the moving board changes, the light from the light emitting element will change even if the IC card is placed in the appropriate position in the card holder. Since there is a risk that light may not be received between the light receiving elements, the moving board requires precision in height position, which poses a manufacturing problem.

Therefore, an object of the present invention is to provide an optical coupling circuit when a movable piece provided in a card holder and which moves from a first position to a second position in response to the insertion operation of the IC card moves to the second position. By configuring the detection means to output a detection signal when the IC card is shielded, the IC card stored in the appropriate position can be elevated without being affected by changes in the height position of the moving piece of the IC card depending on the type of card holder. The object of the present invention is to provide a detection device that can perform accurate detection.

[Means for Solving the Problem] In order to achieve the above object, in the present invention, an IC card inserted from a card insertion slot is stored in a card holder, and information is exchanged with the IC card. (IC car) <In the reader/writer, a movable piece provided in the card holder moves from a first position to a second position in response to the insertion operation of the IC card, and this movable piece moves to the second position. detecting means for outputting a detection signal for determining that the IC card is stored in the proper position of the card holder when the IC card is stored in the proper position of the card holder; the detecting means is formed of an optical coupling circuit; The detecting means is characterized in that the detecting means is formed so that the optical coupling circuit is shielded and the detecting signal is outputted when the optical coupling circuit is moved.

[Operation] According to the detection device according to the present invention, the moving piece provided in the card holder and moving from the first position to the second position in response to the insertion operation of the IC card moves to the second position. By configuring the detection means to output a detection signal when the optical coupling circuit is shielded, the movable piece that moves together with the IC card is not affected by changes in the height position of the IC card depending on the type of card holder, and can be positioned at an appropriate position. The stored IC card can be detected with high precision.

[Embodiments] Next, embodiments of the detection device according to the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1(a) shows one embodiment of the present invention, and is an overall perspective view of an IC card leak writer viewed from the bottom.

In the figure, reference numeral 10 indicates a coil substrate 24a.

24b is shown, and this circuit board 10 is fixed to the bottom of the cover plate 14 and forms part of the guide passage of the card holder, which will be described later.

That is, as shown in the cross-sectional view of FIG. 1(b), the card holder 27 has a lid in which a recess 22 is bent and has a substantially U-shaped cross section for guiding and regulating the IC card 2 in the elongated direction. It is composed of a plate 14 and a circuit board 10 which is integrally coupled with coil boards 24a and 24b to be fixed to the lower surface of the cover plate 14 with machine screws 23.Furthermore, the card holder 27 has a substantially U-shaped cross section. Formed chassis 12
It is fixed with a predetermined gap maintained within.

In this case, the gap is defined by three spacers 16 on the top surface of the lid plate.
Fix by caulking a, 16b, 16c,
Chassis 1 has tapped holes formed at the tips of these spacers.
It is formed by fastening to the back surface of the top plate 12a of No. 2 with countersunk screws 18.

By installing the card holder 27 inside the chassis 12 in this way, its guide passage 22 corresponds to the IC card insertion slot 15a formed in the center of the operation panel 15 inserted into the end of the chassis 12. .

Furthermore, as shown in FIGS. 1 to 3, the operation panel 15 molded from synthetic resin or the like and inserted into the end of the chassis 12 has a positioning/releasing means 32 in addition to the IC card insertion slot 15a. and a display section 15b are provided.

However, the IC card 20 inserted through the insertion slot 15a of the operation panel 15 slides on the circuit board 10 forming the guide passage 22 and is stored in a predetermined position in the card holder 27.

In this way, the IC card 2 stored in a proper state
0 is the positioning means 26 (for example, JP-A-1-219973
The IC card 20 is properly positioned by engagement with a notch (not shown) formed in the surface of the IC card 20.

The card holder 2 is equipped with a detection device that confirms that the IC card 20 is properly stored in a predetermined position.
It is installed at the rear of 7.

That is, this detection device is configured as follows.

That is, as shown in FIGS. 4 and 5(a), the detection device has an IC card locking part 40 that also serves as a shielding plate 38 at one end, and a tension spring 46 to insert the IC card 20 into the insertion slot 15aftUI. The biasing moving piece 42 and the insertion port 1.5
The tip of the IC card 20 inserted from a is inserted and moved inside the guide passage 22 against the tension spring 46 by a manual operation etc. from the first position where it is locked with the locking part 40 of the movable piece 42. , a detector serving as a detection means that confirms the position of the IC card 20 when it has reached a second position where information can be exchanged using a detection signal outputted by shielding the photodetection circuit by passing through the shielding plate 38; It basically consists of 48.

More specifically, the detection device includes a guide bin 52 having a flange 52a formed on the head thereof on the card holder 27 to engage with an elongated portion 50 formed on the movable piece 42 and guide the movable piece 42. A fifth

On the other hand, a transmissive photointerrupter 48 as a detector 48 is mounted on the circuit board 10, and an IC card is artificially stored in a groove 48a formed in the center of the transmissive photointerrupter 48. When the shielding plate 38, which moves with the operation, enters, the light is blocked so that its position can be detected.

In this case, since the slit width for position detection in this light detector is minute (0.25 nm), it is possible to accurately detect the position of an IC card stored in a proper state6. By outputting a detection signal that confirms the IC card 20 stored in the position, it becomes possible to exchange information with the IC card. In this case, the various states of the IC card stored in the card holder, that is, the insertion/standby state and the signal exchange state, are determined by the lighting display of the light-emitting element 17, which is a display section that displays a monochrome display in a different color depending on the mode. This can be confirmed by the change in color.

0 In other words, when the transfer of information between the IC card and the IC card is completed, the color of the display section is changed, and when the IC card 20 releases the card positioning means 26 by an artificial operation of the positioning release means 32, the IC card 20 is discharged by the biasing action of the spring of the movable piece 42 that is engaged with the IC card (see FIG. 4).

[Effects of the Invention] As is clear from the embodiments described above, the detection device of the present invention is provided in a card holder and moves from the i-th position to the second position in response to the insertion operation of the IC card. By configuring the detection means to output a detection signal when the optical coupling circuit is blocked by the movement of the moving piece to the second position, the height position of the moving piece of the IC card can be adjusted depending on the type of card holder. The position of the IC card can be detected with high precision without being affected by changes.

Therefore, the reliability of information exchange with the IC card in the IC card leak writer can be further improved.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and it goes without saying that various design changes can be made without departing from the spirit of the present invention.
