Abstract
PURPOSE: To perform the time correction in the direction of an increase or a decrease only with the rotation of a crown and to change the correction speed with the rotation speed of the crown by detecting the rotation direction of a rotary switch that is normally or reversely turned by the crown.
CONSTITUTION: When the crown 20 is normally turned, contact signals are provided as the output from the rotary switch in the order of S1, S2 and S3, and pulse signals appear at the output in the order of D, E and F through a latch circuit 8 and pulser circuits 12W14. And the addition correcting-signal X corresponding to the number of said pulse signals is produced by the direction detecting circuit 15 and the first correcting-signal gates 26. The signal X is fed to an up-count input terminal of a time counter 4 in order to correct the content of the time counter 4 so that the content may be increased. Also when the crown is reversed, the subtraction correcting-signal Y is produced and fed to a down-count input terminal of the time counter 4 in order to perform the correction in the direction of a decrease.
