<p><P>PROBLEM TO BE SOLVED: To prevent that an excessive load is imposed on a drive source driving a shutter, in an shutter opening/closing structure in a non-contact type IC medium processor. <P>SOLUTION: The shutter 11 is turnably supported such that the shutter 11 moves, with a shaft 27 as a turning center, between a position wherein the shutter 11 covers a space above a placing part 15a and a position wherein the shutter 11 releases the space. A rack member 36 is slightly turnably supported at a support plate 35 fixed to a side part 11A of the shutter 11 through bolts 37, 37 with the shaft 27 as the turning center. The rack member 36 is elastically held by a pair of tension coil springs 38A, 38B suspended between the support plate 35 and both end parts such that a neutral position is held. A rack 36b formed in the rack member 36 meshes with a pinion 32a rotating by drive of a motor. A movement detection means 41 detects that the rack member 36 slightly moves from the neutral position, so that the drive of the motor stops. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
