Abstract

PURPOSE:To more stably and accurately record and/or reproduce information by exposing only the non-recording area of a card-type recording medium to the external part of the title device when the device is placed at a card removing standing by position. CONSTITUTION:At the time of ejecting a card, when a motor 8 and a pinion gear 9 are rotated reversely, and a spur wheel 10a is rotated reversely, a plate member 12 and a spur wheel 11 are rotated and moved in a separating direction from a spur wheel 10b around a shaft 23a and stopped at a position on which the plate member 12 is abutted on a stopper member 15. Consequently, since rotation power for the spur wheel 10a is disconnected, and a card 1 cannot be carried farther than the place up to which a feeding roller 3a can carry the card, the card is stopped automatically at a position where the edge of a card inserting port 2 and the edge of the card 1 are overlapped. Further, under this state, since one part of the card inserting port 2 is notched, only the part of the non-medium surface of the card 1 can be held in order to pull out the card. Thus, it can be prevented to hold a medium surface carelessly and to stick a fingerprint, etc., on the medium surface, which have a ban influence on recording and reproducing.
