PURPOSE:To perform the correction of time through the intermediary of a simple, small-sized and highly reliable means for detecting the displacement by detecting the magnetic field generated by a permanent magent and the like being displaced in linkage with an outside operating member and by controlling thereby the speed of the electrical time correction. CONSTITUTION:When a push-button 2 is pressed in, the permanent magnet 15 of a lever 13 is moved in linkage and is displaced in accordance with the button 2. The change in a magnetic field generated by the magnet 15 due to the displacement is detected by the magnetism resisting element, etc. of a semiconductor hole element 16', etc. Accordingly, when the frequency-dividing pulse for time correction caused by an electric signal detected corresponding to the displacement of the button 2 of the element 16' is selected, the time correction can be performed at a speed corresponding to the displacement of the outside operating member through the intermediary of the simple, small-sized and highly reliable displacement detecting means not requiring any capacitor and the like. In addition, the same effect can be obtained even by generating the magnetic field by means of a coil etc. in place of the permanent magnet. |
