Abstract:
The ribbon winding unit is equipped with a first moving gear, a second moving gear, a first intermediate gear, a tumbler gear, and a winding member. The first intermediate gear engages with the first moving gear when the first moving gear and the second moving gear move in a given direction, and disengages from the first moving gear when the first moving gear and the second moving gear move in an opposite direction. The tumbler gear engages with the first intermediate gear, engages with the second moving gear when the first moving gear and the second moving gear move in the opposite direction, and disengages from the second moving gear when the first moving gear and the second moving gear move in the given direction.
Abstract:
The time recorder comprises a casing comprising gears (428) rotatably supported by the casing and a motor rotating the gears (428); a printing unit provided within the casing and comprising a carriage (210) provided slidably in the X-direction and comprising a print head (213) and longitudinal racks (420) extending in the Y-direction and intermeshing with the gears (428); and a controller controlling the motor. As the motor runs according to the control of the controller, the gears (428) rotate and the printing unit (20) moves in the Y-direction.
