Abstract
A contact member supporting member is pivotably supported to a slide member which abuts on a part of an IC card to be inserted and is moved by the IC card. When the slide member moves, the supporting member also moves. The supporting member is swung in the direction of the IC card by fixed cams. Thus, contact members of the supporting member come into contact with contacts of the IC card. Since the contact member supporting member moves together with the IC card, the contact members do not slide on the surface of the IC card. Therefore, the abrasion of the contact members and the damage of the IC card which are caused by the slide friction between the contact members and the surface of the IC card, and the like can be prevented.
Claims7
An IC card reader comprising:
- guide means, provided for a frame of the IC card reader, for guiding an IC card so as to be smoothly inserted and ejected;
- a slide member supported to said frame so as to be movable in the inserting and ejecting directions of said IC card and having a receiving projecting portion to move said slide member in the inserting direction of the IC card in contact relation with a part of the inserted IC card;
- a contact member supporting means having a plurality of contact members adapted to come into contact with a plurality of contacts of the IC card and pivotally supported to said slide member so as to be freely swung;
- first urging means for urging said slide member in the ejecting direction of the IC card;
- second urging means for urging said contact member supporting means in such a direction that said contact members are away from a passageway of the IC card;
- said first and second urging means being formed by a spring which is attached between said frame and said contact member supporting means;
- and
- a fixed cam fixed to said frame, in which when said slide member is moved in said inserting direction through said receiving projecting portion by the IC card being inserted, said fixed cam comes into contact with a part of said contact member supporting means that is moved in said inserting direction and rotates said contact member supporting means against the urging force of said second urging means in such a direction that said contact members come into contact with the IC card.
An IC card reader comprising:
- guide means for smoothly guiding an IC card into and from a passageway of said reader;
- a contact mechanism for bringing contact members into contact with contacts on a surface of an IC card inserted in said passageway when the IC card reaches a predetermined position;
- a first spring member having one end portion urged toward the passageway by the spring elasticity, and a fixing member attached to said one end portion for depressing an IC card which is inserted to said predetermined position into said passageway;
- and
- a second spring member having one end portion arranged over the one end portion of the first spring member, the one end portions of the first and second spring members coming into contact with each other by elevating displacement of the one end portion of the first spring member upon the insertion of the IC card in said passageway to the predetermined position, said first spring member, fixing member and second spring member defining a sensor upon contact of the one end portions of said first and second spring members for detecting insertion of the IC card to said predetermined position and said first spring member and fixing member further providing a depressing force for holding said IC card in position.
