Abstract

PURPOSE:To attain the connection to an external instrument with simple operation by forming a pocket accommodating an IC card at the rear face of a front plate turned around one side and providing a contact block in contact with a contact of the IC card to a base plate. CONSTITUTION:In stretching and opening a card accommodating body 1 and pressing the tip of the IC card obliquely downward along a pocket member 12, the card slides the inside face of the pocket member 12 and is moved to a reception member 13 while being pressed onto the front plate 11 by a plate spring 16. In pushing down the body 1 against the force of the spring 21 in this state, a pin 41 of a connector block 4 contacts the contact of the card, the block 4 and the pin 41 are pressed downward while following the bent and curve of the card and the this side of the card is connected to a position member 23. When the card is normal, the card is pushed down while being contacted with the reception member 13 and pressed in the depth along a slope 23a, a pin 17 is engaged with a heart lever 24 so as to lock the body 1, a limit switch 5 is turned on at the same time and the loading is completed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a reading/writing device for a card-shaped storage medium incorporating a semiconductor storage circuit.

(Prior art) As shown in Figure 1, an electrically rewritable non-volatile memory, or EEFROM (a), and a CPtJ (b) that controls its operation are embedded in a card-like substrate (c). A storage medium (e) whose surface is provided with contacts (d) for connection with an external device is called an IC card, and has a larger storage capacity than a magnetic card made of magnetic strips, and also requires less RAM and batteries. It is attracting attention as a next-generation data storage method because it is thinner and lighter than a built-in Rampunk, and does not require a backup power supply for memory retention.

By the way, this IC card has the problem that it is easily warped or bent due to its V+b shape, and furthermore, it is difficult to connect to external equipment because the contact points are small.

(Objective) In view of the above problems, an object of the present invention is to provide an IC card reading device that can be connected to an external device through a simple operation.

That is, the feature of the present invention is that the back side of the top plate rotates around the negative side. In addition to forming a Pocken) that accommodates the IC car 1~, a connector bin is mounted on the base in a swinging manner, and connection to external equipment is made possible by closing the Pocken). At the point.

(Structure) Therefore, the embodiments illustrating the details of the present invention will be described below.
I will explain next.

FIG. 2 is a cross-sectional view of an apparatus showing an embodiment of the present invention, and reference numeral 1 in the figure is an IC card accommodating body, the negative side of which is rotatably provided on a base 2 by means of a hinge, and when opened. spring 2
The top plate 11 stops at an angle of approximately 30° due to the force of 1.
and a pocket member 12 provided on the back side thereof, the width and depth of which correspond to the length and width of the IC card, respectively,
There is a receiving member 13 on the back side of the bokeh member 12, and notches 14 and 14 for card ejection on both sides of the front side (Fig. 3A).
Further, a window 15 is formed at a position corresponding to the contact point of the IC card, and a leaf spring 16 is provided inside the bracket to press the IC card against the top plate 11 to prevent rattling. 2 is the base mentioned above, and in the position facing the contact part of the IC card loaded in the pocket member 12, the back side is 1) 11 separated from the frame body with a U-shaped cross section. A connector block holding member 22 (FIG. 3B) is formed, in which a connector pin 4, in which connector pins 41, 41, etc. connected to a cart interface (not shown) are implanted so as to be elastically movable, is attached via a compression spring 3. I'm wearing it
The connector pins 41, 41, . On the front side of this base 2, there is a slope 23a that the front end of the IC cart comes into contact with when the IC card is properly loaded into the pocket member 12, and a flat surface that comes into contact when it is floating from the receiving member 13. The positioning part 23 forming the part 23b is implanted, and when the card accommodating body l is closed, the card is moved in the back direction and the card is positioned at the standard position by the receiving member 13. ing.

In addition, the reference numerals 17 and 24 in the figure indicate a pin and a lock member that can be opened and closed by pressing the IC cart accommodating body 1 from two parts, respectively, and 5 indicates a lock member.
Each shows a limit switch that detects whether the card accommodating body is closed.

In this embodiment, when the card accommodating body 1 is opened and the tip of the IC card is pushed diagonally downward along the pocket member 12, the card slides on the inner surface of the pocket member 12.
It moves to the receiving member 13 while being pushed by the top plate 11 by the leaf spring 16. In this state, when the container 1 is pushed down against the force of the spring 21, the pins 41, 41, etc. of the connector block 4 come into contact with the contacts of the card, and the connector block 4 and The pins 41.41 are pressed downward while following the warping and bending of the card, and the front side of the card comes into contact with the positioning member 23.23. When the front side of the card comes into contact with the positioning member 23.23 in this way, if the card is floating from the receiving member 13, it rides on the flat part 23b of the positioning member 23 and becomes unable to rotate any further. Limit switch 5 cannot be turned on.

In this case, load the card again. When the card is loaded normally, the card is pushed inward along the slope 23a and further pushed down while contacting the receiving member 13, the pin 17 engages with the heart lever 24, and the storage body 1 is pushed down. The limit switch 5 is turned on at l'l l14j-, and loading is completed. Since this limit switch 5 is ONI (4), when reading from the keyboard not shown or manually inputting a fortune-telling command, a signal is output to the IC card via the connector,
Reading and writing are performed.

When writing and reading are completed, container 1 is set to i, I.
When pressed once, the pin 17 and the lever 24 are released and the lock is released, and the opening is expanded by the biasing force of the spring 21. In this state, insert your finger from the front of the container 1 and open the pocket member 12! IC exposed from ilJ notch 14
Hold the card with your fingers (=J) and pull it toward you to insert the IC card.
Take out the card from the blur 71-.

(Effects) Second, as explained, according to the present invention, a pocket for accommodating an IC card is formed on the back side of the top plate that rotates around the negative side, and the pocket is brought into contact with the contacts of the IC card on the base. Since the contact block is provided, the contact pins can follow the position and catch of the IC card, which not only enables a good connection between the IC card and the probe, but also allows the IC card 1ζ to be connected to the connector pin while backed by the top plate. It can be elastically contacted, and there is no risk of deformation even if the device is used for a long time. Furthermore, since the IC accommodating member is stopped in a half-opened state, there is no risk of fingers accidentally coming into contact with the contact pins when loading or removing an IC card, and contamination of the contact pins can be prevented. Can be done.
