<p>PURPOSE:To reproduce information in prescribed sections accurately at constant intervals of time by starting the time measurement of a timer when the starting point of a prescribed information section comes to a reproducing gate and by first starting the normal drive of a film when the measured time reaches a set time. CONSTITUTION:Control circuit means 47 and 53 which set and store the starting and ending points of recorded information in a prescribed section of a film and drive the film forward and backward with switches 69 and 70 when the starting and ending points of the information come to a reproducing gate are actuated by turns, and a counter device 71 reproduces the information in the prescribed section repeatedly. When the starting point of the information comes to the reproducing gate in repetitive playback mode, a timer device which is not shown in the figure starts time measurement by a control signal generated in response to the operations of the switches 69 and 70 and when the measured time reaches a constant time set by a time setting means, a control circuit means 47 is actuated and controlled to reproduce information in the prescribed section accurately at constant intervals of time.</p> |
