专利汇可以提供Head plate shifting mechanism of tape player专利检索,专利查询,专利分析的服务。并且PURPOSE: To reduce the operating force and secure a proper shifting action for the head plate of a tape player, by utilizing the motive power of a motor for the working of the head player.
CONSTITUTION: When the pulse-type conduction due to the pack loading is applied to the electromagnetic mechanism, the plunger 1a starts sucking action. Thus the coupling and engaging pin 11 is hooked to projection part 10a of the head plate 10 and then detached from the linear hooking part 70a. Then the rotary cam board 7 is rotated by the auxiliary lever 4, and the notched part 22a of the minor gear 8 turns to secure an engagement between the gears 72 and 8. The board 7 is rotated by the rotation of the flywheel 9 of the belt 15 of the motor pulley 5. The plate 10 is hooked to the hooking part 106 of the lock lever 18 by the rotation of the board 7 and via the hooking element 6 of the spiral cam 75. With rotation of the cam 7, the part 27a touches the gear 8, and a junction can be prevented by the spring 14 of the auxiliary lever 4 between the element 6 of the plate 10 and the hooking part 73 of the cam 70. In such way, an excessive load can be avoided when the tape pack is loaded, thus ensuring a light operation.
