Abstract

PURPOSE:To make easy the synchronism with the analog and digital display in manual correction and to stabilize the code detection of the code plate, by operating the selection circuit with external operation member. CONSTITUTION:Digital display is made by feeding the signal from the frequency divider 2 to the counter 6 by the selection circuit 10, and the encoder 11 is operated with the external operation member such as the crown 9, and the code signal from the encoder 11 is displayed. The member 9 operates the selection circuit 10, the wheel train 4 and the pointer 5 are selected manually at the same time, and the time in synchronizing with the wheel train 4 is displayed on the display unit with the signal from the encoder 11 only at the manual pointer correction. Simultaneously, the code signal from the wheel train 4 rewrites the content of the counter 6 the same as the code signal.
