Filed: 1981-08-28
Abstract: PURPOSE:To detect the amount of tape running, by loading a cassette to a tape transport, turning on a power supply, and automatically running the tape in forward and reverse direction for a prescribed short time. CONSTITUTION:A tape running control means 1 is controlled with an automatic measuring means 2, for tape running amount before each mode such as stop, recording reproduction, fast feed, rewinding and pause is instructed. When a cassete is loaded to a tape transport and a power supply 3 is turned on, both hub shafts for supply and winding sides of the means 1 are turned for a prescribed number of revolutions. A tape running amount calculation and display means 4 calculates the rotating period of the rotary angle of the hub shafts for supply and winding sides and calculates and displays the running position of the tape at present from the difference and the running direction of the tape. During automatic measurement, a signal C controls 5 the sound volume of reproduction of tape to erase sound. When a mode signal is given during the automatic measurement, the mode is changed over to the detection of normal tape running amount. Thus, the amount of tape running can simply be detected automatically.
