ABSTRACT:
The present invention relates to a tape recorder. The tape recorder comprises a pair of reel shafts which accomodate both winding and rewinding reels for a magnetic tape; a pair of capstan shafts each of which rotates in an opposite direction and transfers said magnetic tape in that direction; an idle roller for appropriately rotating each of said reel shafts in two different winding directions of the magnetic tape; a driving motor which is linked and cooperated both with fly-wheels pivoted on each of said capstan shafts and with said idle roller; an electromagnetic relay cooperated with a sensor which senses the end of said magnetic tape; a contact plate which is shifted by said electromagnetic relay to the rotating position of a contact pin pivoted on the fly-wheel of one of said capstan shafts, and which is moved by said pin; a change-over plate which alternately contacts and detaches said idle roller with and from each of said reel shafts so as to let each reel shaft operate the tape-winding movement appropriately; a link plate for linking cooperatively said contact plate and change-over plate.
