Abstract
The circuit (Co) for control and shaping of the drive pulses is controlled by the divider (DIV) and actuates the motor (M). The counter (Cc) counts the pulses of the divider (DIV) according to a predetermined modulus, for example (60). With each rotation of the motor (M), the detector (D) emits a signal which is counted by the counter (Cc) having the same modulus as the counter (Co) and whose state is synchronised with the latter. The comparator (Cp) compares the state of the two counters and acts on the circuit (Co) so that it formulates additional pulses or disables the pulses of the divider (DIV) according to the results of the comparison, so that the two counters stay in synchronism. The push-button (4) resets the counter (Cc) to zero for example at the moment of the hourly pip. The number of pulses required to set the hands to time is then immediately formulated by (Co) on command of the comparator (Cp). <IMAGE>
