ABSTRACT:
The present invention relates to a counter feed mechanism as used in digital clock comprising a cam member adapted for advanced rotation and another cam member adapted for delayed rotation both arranged on a common axis so that the advanced rotation of the first-mentioned cam member under a drive force transmitted from a clock mechanism twists a coil spring stretched between both cam members, which is, in turn, charged with energy for rotation of the second-mentioned cam member and, upon rotary displacement of the first-mentioned cam member by a predetermined angle, said second cam member is released to be rotated at once so as to advance a rotary wheel step by step.
