Abstract

PURPOSE: To perform the time correction corresponding to both the direction and speed of the rotation of a rotary switch by correcting the time by means of a rotary switch the fixed and movable contacts of which are in a numerical relation wherein there exists no common divisor.
CONSTITUTION: When a crown is turned, one side of two movable contacts, which are in the numerical relation wherein there exists no common divisor, is made contact with three fixed contacts S1, S2 and S3 in turn. The fixed contacts S1WS3 are connected to a latch circuit 8a, which consists of a set-reset flip-flop 8c and an OR gate 8b and prevents a chattering, and circuits 8d, 8e the configurations of which are similar to said one 8a, and are further connected to pulser circuits 12W14 to produce pulse signals D, E and F. The addition correcting-signal X or subtraction correcting-signal Y is produced from these signals D, E, F to correct the content of a time counter 4.
