Abstract
PURPOSE:To obtain a small-size and light-weight circuit of a simple constitution, by connecting an electric-mechanical converter and a motor in series. CONSTITUTION:When the operation member for tape constant-speed running is operated at a time T1, an H-level signal shown in figure A is supplied to an input terminal 66, and a transistor (TR)Q1 is turned on, and the potential at a point B is set to the earth potential as shown in figure B, and TRs Q2 and Q3 are turned on, and potentials of points C and D are equal to the potential of a point E as shown in figures C and D, and power is supplied to a solenoid plunger 48 to drive it. The potential at the point C is lowered as shown in figure C according as a capacitor C3 is charged, and a voltage shown in figure G is applied to the solenoid plunger 48 from the time T1, and a current to drive the solenoid plunger 48 is not flowed to stop the operation. At this time, a current is flowed between points C and D, and a voltage shown in figure F is applied to a motor 16, and the motor 16 is rotated and driven.
