Title:
ANALOGUE ELECTRONIC TIME PIECE WITH TIMER
Document Type and Number:
Japanese Patent JPS5938678
Kind Code:
A
Abstract:

PURPOSE: To make it possible to confirm the set time of a timer visually in an analogue manner, by displaying the set time set by the manipulation of an external manipulating member for setting the timer by the display positon of a hand.

CONSTITUTION: When an external manipulating member 5 is drawn out, a signal Sb comes to Hi and a timer setting mode is established. A min counter 13 is reset and coincidence with a sec hand position counter comes off while the output signal Ye of a coincidence detecting circuit 20 comes to Low and a motor driving control ciruit 21 selects a 16Hz signal 16 as a motor driving signal M until the sec hand position counter is coincided with the content (0 min) of a min counter 13. When an external manipulating member 4 is pushed once, a signal Sa' instantaneously comes to Hi and the min counter 13 is raised to bring the signal Ye to Low to send a sec hand by one step. Every time when the external manipulating member 4 is pushed once, the sec hand is also sent forward by one step and, during the timer setting mode, the sec hand always indicates the position of a timer setting time.
