Abstract

PURPOSE:To precisely decide the timing of the contact conduction of a contact point in a reading/writing device with the electrode of and IC card and timing with the position detection of the IC card by shifting a lever of a plunger for inserting and detecting the IC card. CONSTITUTION:When the IC card 1 is inserted, a first slider 2 shifts, the lever 9 locks the IC card 1 and a contact point holding plate 13 equipped with the contact point 12 by a cam part 2b provided on a first slider 2, whereby the IC card is brought into conductive contact with the electrode. The notching part 3b of a second slider 3 is simultaneously locked to the bending part 6a of the lever 6 which interlocks with the plunger 21. The head part 21a of the plunger 21 pressurizes the movable piece 27 of a leaf switch 26 which has been arranged in the head part 21a of the plunger 21, and the leaf switch 26 is set to an ON-state, whereby the position of the IC card 1 is detected. Thus, these timing can precisely be decided.

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an IC card read/write device for reading information stored in an rC card or writing information to an IC card.0 Prior Art Fig. 4 ~ Figure 7 shows a conventional example. Figure 4 shows IC card 1
FIGS. 6A and 6B show the state before the IC card 1 is inserted into the read/write device, and FIG. 6 shows the locked state after the IC card 1 is inserted into the read/write device.

IC from the IC card insertion slot 1'91L of the main body panel 19.
When the card 1 is inserted, the tip of the IC card 1 hits the L-shaped part 2& of the first slider 2, and then the IC card 1
As the slider 2 is inserted, the first slider 2 also pushes the second slider 3.

The moving distance of the first slider 2 until the second slider 3 starts moving is determined by the length of the elongated hole 3a provided in the second slider 3, and this is determined by the length of the elongated hole 3a provided in the second slider 3.
and the second slider 3 by a support shaft 4 provided between the two sliders 3 and 3. By further inserting the IC card 1, the second slider 3 moves, and the lever 6 held by the spring 5 provided on the plunger 21 of the solenoid 20 rotates around the support shaft 7. , hook part 6 of lever 6
1L is locked into the notch 3b of the second slider 3, and the lever 9 connected to the second slider 3 and the support shaft 8 rotates around the support shaft 10, and the L-bending portion 91L of the lever 9 rotates. , locks the other end of the inserted IC card 1, positions the IC card 1, and locks the other end of the inserted IC card 1.
The electrodes provided on the card 1 are positioned. Also, when the first slider 2 is moved by the IC card 1, the first
The support shaft 1 is supported by the cam portion 2b provided on the slider 2
A contact holding plate 13 having contacts 12 rotatably supported by the IC card 1 rotates and makes conductive contact with the electrodes of the IC card 1. Note that 17 is a spring that supports the contact holding plate. When ejecting the IC card 1, the button tip 142L is pressed by operating the head 21& of the plunger 21 of the solenoid 2o with the ejection button 14, and the lever 6 rotates to move the notch 3b of the first slider 3. At the same time, the hook portion 6a of the lever 6, which is locked to The card 1 is ejected, and at the same time the contact holding plate 1
3 is also rotated by the spring 17, and the contacts 12 are separated from the electrodes of the IC card 1. As another method of ejecting IC cards, use the solenoid 2o to rotate the lever 6! Plunger 21 held by lever 6 to which air signal is applied
, and perform the operations described above. In the conventional technique for detecting the electrical position of the IC card 1 during these series of operations, as shown in FIGS. 5, 6, and 7, the lever 22 of the microswitch 22 is Press to turn the micro switch 0N-OFF to detect the position, or press the leaf switch 2 with the tip of the IC card 1.
Push the movable piece 25 of No. 4 and turn the leaf switch 24 to 0N-
It was turned off and the position of the IC card was detected. Note that 18 is a spring and 29 is a lead wire portion.

Problems to be Solved by the Invention As described above, in the conventional configuration, the micro switch 22 or the leaf switch 24 is set to 0N by the tip of the IC card 1 or by the second slider 3 that moves when the IC card 1 is inserted. - Position detection is performed with OFF.

However, with the structure of currently available microswitches and leaf switches, the ON-OFF stroke accuracy is poor.
2 and the leaf switch 24 cannot be accurately determined, and the contacts of the read/write device come into contact with the electrodes of the IC card 1 after the card position detection switch is turned on, causing problems such as read/write failures. there were.

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to accurately determine the timing of contact of a contact point of a read/write device with an electrode of an IC card and the timing of detecting the insertion position of an IC card.

Means for Solving the Problems In order to achieve the above object, the present invention provides a detection device that detects the insertion position of the IC card by moving the first lever or the plunger of a solenoid that drives the lever. It is something.

Function With the above configuration, the position of the C card is detected by the movement of the lever that amplifies the minute movement of the first slider when it is locked, or the plunger of the solenoid that is linked to this, so the lead to the electrode of the IC card is detected. The timing at which the contacts of the write device make contact and the timing at which the insertion position of the IC card is detected can be determined with high accuracy, and read/write failures will not occur.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings. Components that are the same as those in FIGS. 4 to 7 will be designated by the same reference numerals, and the description thereof will be omitted. 1 and 2 show the state before the XC card is inserted. When the IC card 1 is inserted through the IC card insertion slot 19a, the first slider 2 moves, and the lever 9 locks the IC card 1 in the order explained in the conventional example, and the lever 9 locks the IC card 1 provided in the first slider 2. Contact 1 by cam part 2b
The contact holding plate 13 equipped with the IC card 1 rotates and moves.
Make conductive contact with the electrode of the Along with this, the second
The notch 3b of the slider 3 locks onto the bent portion 6a of the lever 6 which is interlocked with the plunger 21 of the solenoid 20. At the same time, the head 21 of the plunger 21
The head 21aL of the plunger 21 presses the movable piece 27 of the leaf switch 26 disposed at &, the leaf switch 26 is turned on, and the position of the IC card 1 is detected.

FIG. 3 shows another embodiment, in which the position of the IC card is detected by a detection unit 6c provided on the lever 6 and a photo sensor 28.0 Effects of the Invention According to the present invention, the IC card can be inserted easily. Since detection is not performed by the tip of the IC card or the first slider, but by the movement of a lever that amplifies the minute movement of the first slider when it is locked, or the plunger of a solenoid that is linked to this, the electrode of the IC card It is possible to accurately determine the timing of contact conduction of the contact point of the read/write device with the IC card and the timing of position detection of the IC card, and to provide a highly reliable IC card read/write device.
