Abstract

The carriage of a serial printer (not shown) is intermittently transported to various printing positions along a line of printing by a motor 22 which is part of a servo control system. A pulley 26 is mounted on the shaft of the motor 22 which drives the carriage by a cable arrangement indicated generally as 27. This includes a left cable segment 28 and a right cable segment 29. The cables are coupled to the carriage through a

CABLE/PULLEY DRIVE FOR PRINTER CARRIAGE (Cont'd)

The carriage of a serial printer (not shown) is intermittently
transported to various printing positions along a line of

printing by a motor 22 which is part of a servo control system.
A pulley 26 is mounted on the shaft of the motor 22 which
drives the carriage by a cable arrangement indicated generally
as 27. This includes a left cable segment 28 and a right cable
segment 29. The cables are coupled to the carriage through a

single-grooved pulley 31 which is mounted for rotation on the
carriage.

Cable segments are wrapped around the single grooved pulley 31
in opposite directions in the manner shown in Figure 2. In
this arrangement the forces Fl and F2 applied on pulley 31 by
the cables 29 and 28, respectively, lie in a common plane
perpendicular to the axis of rotation of the pulley and
intersecting its center, thereby avoiding tipping moments
which could produce a drag on the carriage during linear
movement.
