Abstract

PURPOSE:To enhance the operability of a titled device by forming an IC card containing part by a slit-shaped trunk and providing an insertion inlet and mechanisms of contact head lifting and card ejecting on one end and the other end, respectively. CONSTITUTION:When an IC card is inserted from an insertion inlet 4 by pointing a contact downward in the condition where the lock of an IC card receiving member 18 is released, its top abuts on the receiving member 18. When the IC card is pushed to the recess against a spring 20 in this condition, the receiving member 18 is shifted backward, and the spring 20 is suppressed. At the same time, a contact head 26 is lifted to the oblique upward by a link 28, and a contact pin 26a is in contact with a contact point of the IC card, which forms a contact. Simultaneously one claw 14b composing of a locking part is bent by the other claw 14a, and both claws are connected. The IC card is pressed to a contact pin in the condition where the spring 20 is energized, and fixed. When a card is taken out, a releasing member 30 is pressed.

Description

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

(Prior art) As shown in Fig. 1, an electrically rewritable nonvolatile memory, that is, an EEPROM (a), and a CPU that controls its operation (b) are embedded in a card-like substrate (c). A card-shaped storage medium having a contact point (d) for connection with a reading device on its surface is called an IC card, and is attracting attention as a next-generation data storage means.

By the way, this IC card has a thin substrate for easy portability, and is prone to warping and bending.
Moreover, since the contacts are small, there is one difficulty in connecting with external equipment.

For this reason, the applicant formed a pocket for accommodating an IC card on the back side of a lid member that rotates in the vertical direction centering on the - side, and provided contact pins on the base to open and close the top plate. We have proposed an IC card reading/writing device that links sets of IC cards.

This device has the advantage of being able to form contacts and reliably read and write information regardless of warpage or bending of the board; however, it is necessary to open and close the lid when loading and unloading the IC card. First, frequent replacement of IC cards not only lacks mobility, but also has the disadvantage that the lid member occupies a large area on the surface of the device in which it is installed, such as a hand belt computer.

( ] ) In view of these circumstances, the present invention provides a novel device that can reliably form a contact by inserting an IC card through an insertion slot, and at the same time eject the IC card to the outside by operating an ejection rod. The purpose is to provide a copper 1 father device for IC cards.

(Structure) Therefore, details of the present invention will be described below based on illustrated embodiments.

Fig. 2.3 shows an embodiment of the present invention, in which reference numeral 2 denotes a main body of the device, which has an IC card insertion slot 4 at one end and a positioning wall 6 at the other end. It consists of a frame member integrally formed with a shaped IC card storage body 8, a housing 10 in communication with the body in the center of the positioning wall 6, and a guide wall 12 in the lower part that guides the reading head upward at the rear end. , ] - One claw member 14a of a locking tool 14, which will be described later, is integrally formed at the rear end of the slope member 8a, and the other claw member of the locking tool is integrally formed at the rear end of the lower plate member 8b. A window 16 is formed that allows i songs to be played on the 14b.

18 is two compression springs 20. which are interposed between the locking tool.
20, the card holder is a member that protrudes elastically toward the storage barrel 8 side and is provided so as to be interlocked in the card movement direction.The other claw member 14b of the locking tool is integrally formed at the rear, and a lower plate is provided at the lower end. It is constructed by attaching a switch operating member 24 that drives a contact formation detection switch 22 disposed on the member.

26 is a contact head movably housed in the guide chamber 12 of the frame member, and includes contact pins 26a, 26.
The card holder is connected to the member 18 via the link member 28 on both sides with a facing upward, and the holder moves up and down in the left direction (arrow A) in the figure in accordance with the movement of the member 18. It is configured.

Reference numeral 30 denotes a release member that bends the claw 14b of the engagement member downward to release the engagement, and is movable downward between the claw 14a of the upper plate member 8a and the rear end of the lower plate member 8b. It is set in.

In this embodiment, when the IC card is inserted from the insertion slot 4 with the contacts facing downward with the IC card receiving member 18 released, the tip of the IC card comes into contact with the receiving member 18.

In this state, when the IC card is pushed in against the force of the screw 20.20, the member 18 of the receiver moves backwards and the
20.20 is pressed, and at the same time the contact head 26 shown in FIG.
6a and 26a come into contact to form a contact, and at the same time, one claw 14b constituting the engagement II tool is pushed and bent by the other claw 14a, so that the two engage, and a pressing force is stored in the spring 20.20. In this state, the IC card is pressed against the contact pins and fixed. Further, a switch 22 for detecting contact formation is operated by a switch driving member 24, and exchanges information with a computer (not shown).

When the release member 30 is pressed when the information exchange is completed,
One of the claws 14b bends downward to release the engagement, the springs 20 and 20 spring, and the receiving member 18, holding the IC card, is flipped against the side of the insertion slot 4, and at the same time, the contact pad 26 is The IC card is pulled down by the link 28, moves to the insertion slot 4, and can be taken out.

In this embodiment, the retention release member for card ejection is disposed at the rear end, but it can be operated from the insertion slot side by connecting an extension rod or the like.

(Effects) As described above, according to the present invention, the IC card accommodating portion is formed by a slit-shaped body, and an insertion opening is provided at one end, and a contact head lifting mechanism and a card ejection mechanism are provided at the other end. Therefore, not only can the exposed area be made as small as possible and the casing surface of the built-in device can be used effectively, but also a large degree of freedom can be given to the design of the built-in device. Furthermore, since the card insertion force is used to operate the contact head 1 raising mechanism and at the same time the card ejection force is stored in the card ejection mechanism, loading and ejection from the device can be performed extremely quickly. , the usability of the device can be significantly improved.
