Abstract
PURPOSE: To increase duration of a spring plate and smallize force of magnet by providing a mechanism for controlling pressure of spring plate and in regard to print selection lever, each line spring plate increase presuure upon print selection and decrease pressure upon printing operation and gradually increase pressure after half of print wheel returning operation.
CONSTITUTION: Upon print selection operation, a lever 218 for keeping spring plate is rotated in clock direction about an axis 2182 by cams 117, 117 and each line spring plate 217 is raised against a print selection lever 208 so that pressure of the spring plate is increased and get sufficient force for stop of print wheel. Upon printing, engaging of cams 117, 117 with the lever 218 is released and the lever is rotated about the axis 2182 in counter-clock direction and each line spring plate 217 is lowered against the lever 208 so that the pressure of spring is decreased. And after half of return operation of print wheel, the pressure of spring is increased. Thus, the pressure is increased only in print selection operation so that the duration of the spring plate 217 is increased and it allows small attractive force of magnet.
