SMALL-SIZED CASSETTE TAPE PLAYER

摘要

PURPOSE:To attain sure positioning and fixing of a head to a tape by deciding the height of a head with a chassis face used as a reference through the operation of tapered circumferential wall of a pin member projected to a head holding member. CONSTITUTION:A head arm 29 is supported freely rockably to a support shaft 30 implanted to a cassette holder member 101 in parallel with a chassis 75 and when a changeover arm 27 is moved in the direction of PLAY, a pin 29a of the head arm 29 engaged with a square hole 27b of the changeover arm 27 is moved in following to the changeover arm 27 and the head arm 29 is rocked toward D around the support shaft 30 to forward a head 31. Since a circumferential ridge of the square hole 27b is engaged and drawn to the tapered face of the pin 29a, then the head arm 29 is depressed toward the chassis 75 while being rocked, the positioning of the height of the head 31 is conducted to the chassis face and the positioning of the head 31 to a tape is conducted surely.
