Abstract: PURPOSE:To transmit the force set by a computer to an operator by driving an arm mechanism by a pulse motor and a decelerating mechanism and providing a torque sensor on the driving shaft of the decelerating mechanism. CONSTITUTION:The number of pulses driven by a certain operation is counted with respect to each motor to obtain the position of a present indicated point in the coordinate system set by the computer, and the interference with an object set by the computer is calculated, and the repulsive force generated at the indicated point is obtained to calculate the shaft torque of each motor unit 2. This calculated torque value and a torque value 19 which is read by the torque sensor and is inputted to an input/output control part 22 are compared with each other; and if they are different from each other, the rotating direction of a pulse motor 11 is so determined that the torque value of the torque sensor approaches the calculated torque value, and pulses are generated to rotate the pulse motor 11. A driving circuit 24 is operated by a driving pulse 20 outputted from the input/output control part 22, and each pulse motor 11 is turned, and the repulsive force acting on the indicated point is controlled.

Filed: 1995-07-14
Abstract: PROBLEM TO BE SOLVED: To easily recognize timing for performing exposure correction. SOLUTION: A photometric area selected by a second-order position selecting means 15 is monitored by an EVF 11 together with an image from a CCD 3. When an exposure correction execute key 18 is depressed, switches SW1 and SW2 are closed, an AE detection circuit 12 detects the exposing state of the photometric area, an exposure control circuit 13 performs control so that this exposing state can be proper and when it becomes proper, a control value is held. On the other hand, an exposure condition discrimination circuit 20 detects the difference between this exposing state and the proper exposing state and that difference is displayed on the EVF 11. Therefore, since this difference is reduced when the exposing state gets closer to the proper state, a photographer can easily and exactly recognize the timing for depressing the exposure correction execute key 18.
