Title:
OPERATION SWITCHING UNIT OF TAPE RECORDER
Document Type and Number:
Japanese Patent JPS5577045
Kind Code:
A
Abstract:

PURPOSE: To make it possible to lock a fast-feeding or rewinding button according to demands with a simple constitution by prescribing a going movement quantity of the stopping material of a reproducing operation material and a contact pressure for stop.

CONSTITUTION: Reproducing operation material 24d reciprocates stopping material 27 through inclined part 32d according to operations of a reproducing push button. Next, material 24d is stopped by hook part 31d of material 27 simultaneously with returning movement of material 27 dependent upon elasticity of spring 29, and the reproducing push button is locked, and the contact pressure between material 24d and hook part 31d becomes a value to stop returning movement of material 27. Consequently, when a fast-feeding button, etc., are operated in the reproducing mode, material 27 goes by a quantity smaller than the going movement quantity for reproducing operation through fast-feeding operation material 24b different in contact position and inclined part 32e similar to inclined part 32d of material 27, and material 27 does not return, and reproducing and fast-feeding push buttons are locked and unlocked respectively, and simultaneously, the fast-feeding button is locked only when the reproducing button is operated again. The similar operation is performed in respect to the rewinding button.
