DEVICE FOR PREVENTING INFLOW OF IMPURITIES FOR TAPE RECORDER

摘要

PURPOSE: A device for preventing an inflow of impurities for a tape recorder is provided to prevent a generation of defect and to lengthen a life of product by preventing an inflow of floating materials among air into an inside of main chassis. CONSTITUTION: A holder is moved via a guide hole(15a) when a cassette(C) is loaded in the holder(16). A hanging protrusion(17) is inserted in a hanging groove(44). The switching plate(40) opens the radiating hole(32) gradually by moving backward with the holder(16). When the holder(16) is vertically fallen by arriving in a vertical section with passing a horizontal section of the guide hole(15a), the hanging protrusion(17) is removed from the hanging groove(44) and the movement of switching plate(40) is stopped. The vent(42) and the radiating hole(32) are confirmed each other. The opened state of radiating hole(32) is maintained during operating a tape recorder in the state. A heat generated inside a main chassis(10) is radiated to an outer air through the vent(42) and the radiating hole(32).
