Abstract

PURPOSE: To reduce wasteful load and prolong battery life by coupling a data feed Geneva gear and transmission member with a slight backlash at the non- transmission time.
CONSTITUTION: When it becomes 0:00 AM upon lapse of 24 hours, the first transmission member 7 which is formed with a Geneva gear and makes backlash coupling with a drive wheel 6 and the protrusion 6a of the drive wheel 6 couple, causing the member 7 to turn. This causes the second transmission member 8 to be turned by the postioning member 9 provided to the member 7, then a display wheel 2 is fed for 1 day. This minute backlash coupling of the drive wheel 6 and member 7 obviates application of wasteful load on the drive system at the times other than the time when the display wheel is fed, prevents the consumption of unnecessary power and prolongs battery life. When the member 8 is manually turned, the member 8 turns by jumping over the member 9, thus the month end correction or other may be accomplished while checking with tactile sensation.
