Abstract

PURPOSE:To ensure a free variation of both the extent of change and the velocity and thus reduce the deterioration due to the wear, by detecting the induced voltage of a human body, converting the output of the detection into the DC and thus securing the increase/decrease of the gain of the gain control amplifier by said DC. CONSTITUTION:The detector C functions as an operational amplifier of the high- impedance input the like and thus converts the contact or noncontact of a human body into the electric signal. For this output of the detector, only two signals are available at the point on the figure and the lowest point in the metal bar B. The position signal of the bar B is connected to the D/A converter F to be converted into the DC and then applied to the gain control amplifier G in order to vary the level of the video signal or the aural signal. At the same time, the signal connected to the control circuit H is decoded within the circuit H. And a decision is possible whether the starting point of the action is given from the highest-rank side or the lowest- rank side by storing the signal supplied from the route (a).
