Abstract

PURPOSE:To make it possible to switch arbitrarily continuous hand moving and step hand moving, by controlling gates to switch and output one of two kinds of hand moving pulses formed according to combination of frequency division outputs. CONSTITUTION:The output of D type FF24 of switch 22 is inverted according to switching of manual switch 26, and one of outputs O and anti-O of hand moving pulse generating circuit 14 becomes high-level, and AND gate 18 or 16 is opened according to the operation of switch 26. Frequency division outputs from frequency dividing circuit 12 such as 16Hz and 1Hz, 16Hz and 8Hz, and so on are applied to these gates 18 and 16 respectively, and step moving pulse 102 having the quiescent time at every half period of 1Hz and continuous pulse 100 throughout 1Hz whose number is equal to the number of pulses 102 are applied to driving pulse generating circuit 28 from opened gates 18 and 16 respectively, and motor 30 for watch is step- driven or driven continuously, thus switching arbitrarily continuous hand moving and step hand moving.
