PURPOSE:To shift a traveling object accurately to a free position and to shift a CRT cursor of a terminal in the regular direction with a simple device, by detecting the level and the direction of the pressure of hands by an analog detector and delivering a shift pulse from a processor in response to the pressure of the hands. CONSTITUTION:A manual pressure detector of electrostatic capacity type consists of a conductive disk electrode 1 fixed concentrically with a holding stand 3 of fingers, etc. and a conductive disk electrode 2 divided by a spring 4 into four parts along cut parts 5. These electrodes 1 and 2 are set in parallel with each other. Then the four divided disks 13-16 of the electrode 2 are connected to the input terminals of oscillators 6-9 respectively. While the electrode 1 is connected to a common terminal of oscillators 6-9 respectively. The oscillation frequencies of oscillators 6-9 are processed by the difference detecting circuits 10 and 11, preprocessing parts 17-20 and shift processing parts 20-24 respectively. Then a shift pulse is delivered in response to the level and the direction of the pressure detected by said manual pressure detector. Then the compression of pulse is carried out to the weak force through the preprocessing, and the estimated shift processing is performed through the shift processing. Thus the follow-up performance is improved with the manual shift device.
