Abstract

PURPOSE: To enable recording and reproduction only with cassette loading by detecting the operation of loading and unloading of cassette, and to enable cassette unloading by stopping the recording and reproduction, only with unloading of cassette.
CONSTITUTION: In case of reproduction mode, first the entrance of the hand having the cassette 2 is detected with the light emitting element 5 and the photodetector 6, and with the loading of the cassette 2, the slide lever 3 is pushed in to turn on the switch 4. Further, the hand is detached from the cassette 2, to make conductive the photodetector 6, the output Z of the NAND circuit 7 is at low state, the control section 8 produces the reproducing signal for reproduction run. When the hand enters for cassette unloading, it is detected with the detectors 5 and 6. the output Z of the NAND circuit 7 changes to H, the stop signal gives to the control section 8 for halt. Next, when cassette 2 is unloaded, the lever 3 returns to the original position, the switch 4 is off, and even if the hand no longer exists, the output Z of the NAND circuit 7 remains at H to keep the halt condition.
