1)

Configuration

This mechanism consists mainly

of

the carriage motor,

tension unit, wire drum ass'v.wire, carriage unit, pulleys,

andguideshaft.

2) Remarks

The carriage is fed by the

winding of

the wire onto the

wire drum and is controlled by the direction and amountof

take-up. The amount of

carr

i

age feed is determined by

setting

the outer diameter of the wire drum and related

partsso

that

the carriageisfed 0.2 mm peronestep of the

motor.

S

i

milar

to

the paper feeding

mechanism

,

the speed-up/

down gearsection of the wire drum assy is provided

with

a

two-gear

configuration to prevent

back

l

ash during

for-

ward or backward rotation of the

carr

i

age motor.
