Ion transport photoreceptor for electrophotography

In an analogue electronic timepiece comprising a minute hand mounted on a cannon pinion, an hour hand mounted on an hour wheel, a motor driven by pulses produced by an electronic circuit and a gear train connecting the motor pinion with the cannon pinion and hour wheel, means for setting the minute hand and hour hand to amend the time displayed by the timepiece comprises a setting wheel which is rotatable by a crown wheel in one direction for moving the hands clockwise and in the opposite direction for moving the hands counterclockwise. The setting wheel is coupled to the gear train by a friction pinion at a point in the train which is approximately midway between the motor pinion and the cannon pinion and hour wheel so that the blacklash generated in moving the hands clockwise in a setting operation is approximately equal to the backlash generated in moving the hands counterclockwise. The electronic circuit includes means for generating pulses at the conclusion of a setting operation so as to compensate for the blacklash in the gear train. Since the backlash is approximately the same regardless of the direction the hands are moved in the setting operation substantially complete compensation for the backlash can be attained regardless of the direction in which the hands are moved.

Analogue electronic timepiece with setting means

A small sized electric timepiece movement has a radius which is less than the diameter of the battery which powers the movement. Hence, the battery extends from one side of the movement to a point beyond the centerline of the timepiece. Advantage is taken of the fact that the battery is dome-shaped so as to accommodate a portion of the base plate which rotatably supports the cannon pinion and hour wheel of the timepiece movement which are located centrally of the timepiece. Hence, the axis of the cannon pinion and hour wheel, if projected, would intersect the battery. The invention enables the construction of an electronic timepiece which is smaller than would otherwise be possible. With a battery having a diameter of 7.9 mm and a thickness of 3.5 mm, it is possible to make a timepiece having a diameter of 14.8 mm and a thickness of about 4 mm.
