Title: Damper device for carriage
Inventor: TAKEMOTO TAKESHI
IPC: B41J19/08
Filed: 1980-03-26
Abstract: PURPOSE: To improve printing speed by a mechanism wherein a friction providing member containing an electromagnet is mounted, frictional force is increased when starting and frictional force is decreased when stopping by changing currents flowed through the electromagnet, in a damper device for a carriage.  
     CONSTITUTION: A hole 13 is formed at the upper plate side of a carriage base 11, opposing to a stator 6, and a frictional force providing member 14 is mounted by utilizing the hole. The frictional force providing member is supported by an electromagnet 15, a friction member 16 and flat springs 17. When currents flowed through the electromagnet are set at zero when starting and at large value when close to stopping time, only slight frictional force by the flat springs 17 is generated when starting and the carriage base is quickly started, and magnetic force increases when approaching to a stopping location, frictional force by the sucking force of the electromagnet functioning to the stator through a sucking hole 18 is added to frictional force by the flat springs and the carriage base is rapidly stopped at a designated location.
