ABSTRACT:
A cassette type tape recorder, wherein, when a 2-reel type tape cassette is inserted in the lengthwise direction into a cassette-receiving section provided in a base board of a tape recorder, a push pin fixed on a drive mechanism-carrying board is depressed by the inserted tape cassette, causing the drive mechanism-carrying board to be lifted while being carried forward in the same direction as that in which the tape cassette is inserted into the cassette-receiving section; a reel drive shaft and capstan drive shaft mounted on the drive mechanism-carrying board are inserted into the tape cassette from below; one end portion of a magnetic head-carrying board fitted with a magnetic head and pinch roller is rotatably held by a magnetic head support pin fixed to the drive mechanism-carrying board; a cam pin provided at the other end of the magnetic head-carrying board is inserted into a cam hole obliquely bored in the base board of the tape recorder; and the magnetic head-carrying board is guided into the cam hole while being carried forward in the moving direction of the tape cassette as the result of the forward movement of the drive mechanism-carrying board and approaches the tape cassette, thereby causing the magnetic head and pinch roller to contact a magnetic tape received in the cassette.
