发明名称 CARD INSERTION DETECTING MECHANISM
摘要 <p><P>PROBLEM TO BE SOLVED: To provide a card insertion detecting mechanism for a card reader detecting both ends of a card by one set of photocouplers. <P>SOLUTION: When a normal card 14 is inserted in a card traveling face 28 and it passes slit 16, pressing by a card 14 rim edge acts on a portion d shielding a slit 16 end of detection arm tips 22e and 23e of detection levers 22 and 23, and the detection levers 22 and 23 are turned toward mutually opposite arrow CW and CCW directions against biasing forces of torsion coil springs 24 and 25. Shading arm tips 22d and 23d turn integrally with the detection levers 22 and 23, and shielding of a photocoupler 18 light projecting path P is removed. A shutter of a card conveyance path is opened on the basis of a light receiving signal of a photocell 18c. <P>COPYRIGHT: (C)2004,JPO</p>
