<p>PURPOSE:To reduce the number of parts and achieve the reduction in the thickness and weight of the apparatus by simultaneously controlling both of an accidental erasing protecting lever and a record-playback switch with an accidental erasing protecting lever control pin and letting a lock lever be actuated by one sloped face of a recording lever. CONSTITUTION:When a rcoring state is set, the accidental erasing protecting lever control pin 108 of a recording lever 13 falls. Then, the deformed hole 2a of an accidental erasing protecting lever 20 disengages from the control of the pin 108 and is turned by the action of an accidental erasing protecting lever spring 83, causing its accidental erasing protecting detection end 20c to detect the fin 6a of an accidental erasing detection hole 6. At this time, the end 20b of the lever 20 does not interfere the stopper 13a of the lever 13 and therefore the lever 13 advances straightforward, and the other recording-playback switch lever 43a freely fitted to the pin 108 is cooperatively pushed in, by which the recording-playback switch 43 is sealed in the recordig side. Next, when the fin 6a is cut off, the lever 20 turns by being disengaed from the control by the pin 108, causing the detection end 20c to enter the detection hole 6 to prohibit further entry of the lever 13. Thereby, the number of parts may be reduced and the apparatus made thinner and lighter in weight.</p> |
