<p>PURPOSE:To obtain an operation mode selector having high performance and high operability, by providing a partial pressure detector which supports a pressure panel at several points and detects the partial pressure at each support point and controlling the operation mode by the pressing position and the tape speed by the pressing force. CONSTITUTION:When a pressure panel 10 supported at several points, the electric signals corresponding to the pressure received from pressure detectors 16a-16d are supplied to adders 44a-44c. Then addition output signals of detectors 16c and 16d, 16b and 16d and 16a-16d are sent to divider circuits 48a and 48c. Thus the signals of adders 44a and 44b are divided by the signal of the adder 44c. The coordinates x and y of the pressing position on the panel 10 are delivered through terminals 50a and 50b and supplied to a position converting circuit 54 via A/D converters 52a and 52b. The position signal of an operation mode region is sent to an operational comparator 56 and a signal processing circuit 64 to control an operation mechanism 62. While the tape speed, etc. are controlled by the output signal of the circuit 44c via a motor circuit 70. In such a way, both performance and operability are improved for an operation mode selector.</p> |
