Abstract

Disclosed is a mechanism of flexible link connection by a compression coil spring. Fig. 1 shows an example of the mechanism which is picked up on a printer with dual paper feeding path. It consists of Link-A 1, Compression Coil Spring 2, Link-B 3 and Selector 4 for switching the dual paper path. When Link-A 1 is actuated counter-clockwise, Selector 4 turns lock wise. In case of Link-A 1 being over-actuated against movable range of Selector 4, distortion of Compression Coil Spring 2 compensates it. Fig. 2 shows all components of the mechanism. Electro-Magnetic Solenoid 5 (pulled position shown) has two roles which are to transfer driving torque from Belt 6 to Gear-A 7 for lower paper path or Gear-B 8 for upper paper path, and to select paper path by Selector 4.

Flexible Link Connection by Compression Coil Spring

   Disclosed is a mechanism of flexible link connection
by a compression coil spring.  Fig. 1 shows an example of the
mechanism which is picked up on a printer with dual paper feeding
path.  It consists of Link-A 1, Compression Coil Spring 2, Link-B 3
and Selector 4 for switching the dual paper path.  When Link-A 1 is
actuated counter-clockwise, Selector 4 turns lock wise.  In case of
Link-A 1 being over-actuated against movable range of Selector 4,
distortion of Compression Coil Spring 2 compensates it.  Fig. 2 shows
all components of the mechanism.  Electro-Magnetic Solenoid 5 (pulled
position shown) has two roles which are to transfer driving torque
from Belt 6 to Gear-A 7 for lower paper path or Gear-B 8 for upper
paper path, and to select paper path by Selector 4.  In the
mechanism, both of appropriate gear engagement and complete upper
paper path are functional requirements.  Although they depend on
Solenoid 5 mounting position adjustment, it is difficult to obtain
both of them at a time.  Though usual adjustment procedure would be
(1) Adjustment of Solenoid 5 position for gear engagement condition,
then (2) Adjustment of angular relationship between Link-B 3 and
Selector 4.  However, use of Compression Coil Spring 2 can delete
the procedure (2) because of its distortion after Selector 4
contacts with Bed Plate 9.
