DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to an IC card device which holds an IC card which stores data such as personal information in fields of communication, finance, medical care and the like.
BACKGROUND ART
An IC card comprises a card-shaped or card-like plate and an integrated circuit which is buried in the plate. The integrated circuit includes a microprocessor unit and a memory, and is formed on a one-chip of a semiconductor chip. In recent years, the IC card is widely put into practical use in the fields of communication, finance, medical care and the like, because the IC card has superior features about multifunction and security for stored data in the memory. For example, in the communication field, the IC card is used as a prepaid card for a public telephone, a user identification card for a portable telephone, etc. As the IC card has become popular in such a manner, installation of equipment such as public telephone machines and cash dispensers which incorporate an IC card device for holding the IC card and for reading data is becoming popular.
In the following, a description will be given on a conventional IC card device which is described in Japanese Patent Application Laid-Open Gazette No. 63-244187, for instance, with reference to FIGS. 15, 16 and 17.
FIG. 15 is a plan view showing a state before an IC card is inserted in conventional IC card. FIG. 16 is a plan view showing a state after the IC card is inserted in the conventional IC card device shown in FIG. 15. FIG. 17 is a cross sectional view taken on line XVII--XVII in FIG. 16. In FIG. 17, however, for simplicity of illustration, springs 70, 71 are omitted.
As shown in FIGS. 15, 16 and 17, a conventional IC card device 51 includes a first card discharging member 52 which is moved in an insertion direction X of an IC card 50 as the IC card 50 is inserted, having an L-shaped portion 52a which contacts a tip portion of the IC card 50 to be inserted, a second card discharging member 53 which is linked to the first card discharging member 52 by pins 61, 62 and which can be moved in the insertion direction X as the first card discharging member 52 is moved, a discharge-deterring member 54 which is linked to the second card discharging member 53 by an axis 63 and which can be rotated about the axis 63, and a card holding member 55 which is linked to the second card discharging member 53 by an axis 64 and which can be rotated about an axis 65. A hook portion 54a is formed at one end of the discharge-deterring member 54. When the IC card 50 is inserted at a predetermined position within the IC card device 51 (hereinafter referred to as "reading position"), the hook portion 54a is engaged with a notched portion 53a of the second card discharging member 53, so that the second card discharging member 53 is locked. Further, when the IC card 50 is inserted at the reading position, a bent portion 55a formed at one end of the card holding member 55 latches a rear edge of the IC card 50 within the IC card device 51, to thereby block a discharging path for discharging the IC card 50. Thereby, it is possible to prevent the IC card 50 from getting discharged during the insertion of the IC card 50.
Further, the IC card device 51 comprises an electromagnetic solenoid 56, which is linked with the discharge-deterring member 54 for discharging the IC card 50 which is inserted as an electric signal (hereinafter "discharge signal") is received from a control device not shown. A bent portion 54b formed at the other end of the discharge-deterring member 54 is linked with a plunger 56a of the electromagnetic solenoid 56 through a spring 73.
The IC card device 51 comprises a contact holding plate 57 which includes a plurality of contact terminals 57a and which is rotated about an axis 66 in association with movement of the first card discharging member 52, and a card rear edge detector 58 which detects the insertion of the IC card 50 at the reading position based on the movement of the first card discharging member 52.
Next, an operation of the conventional
