Abstract

PURPOSE:To easily and quickly execute the repeated reproducing of a reviewed part with the aid of a simple operation by executing reverse searching and automatically shifting a mode to a reproducing mode based on the count of a CTL pulse when a specified operation key switch is turned on during the reproducing. CONSTITUTION:A key matrix 7 is connected to a microcomputer 6 and the plural operation key switches 12 including the operation key switch for reproduc ing 8 which executes quick repeat during the reproducing are provided to the plural contact parts thereof. In such a case, when the operation key switch 8 is turned on, a magnetic tape is rewound and the control pulse (the CTL pulse) on the magnetic tape is counted extending over a prescribed time at the time of rewinding. Then, the mode is automatically shifted to the reproduc ing mode. Thus, when there is the part which is overlooked or which is desired to be viewed again while a VTR is reproduced, the reverse searching and the reproducing are automatically executed only by turning on the key switch 8. As the result, the operation for repeatedly reproducing the reviewed part is easily executed.
