Figure 2-11. Disengage & Clutch mechanism
The Clutch mechanism transmits the ASF motor drive to the LD roller shaft only when
the Clutch gear rotates CW direction after the Change lever releases the Clutch lever. If
the Clutch gear rotates CCW direction, the ASF motor drive is not transmitted to the
LD roller. This is due to the combination of the shape of the Clutch gear and the Clutch
lock tooth such as described on the figure.
1.
When the ASF motor rotates CW direction, the Change lever is set on the Clutch
lever and the Clutch is pushed down as above Step1’s figure. As the result, the
Clutch gear is released from the Cluck lock tooth and the drive from the ASF
motor is not transmitted to the LD roller shaft.
2.
When the ASF motor rotates CCW direction in the above Step2’s figure, the
Change lever moves to the left direction with the CCW rotation of Combination
gear 37.6, 44.4. The Clutch turns back to the engagement position by the tension
force of the Tension spring 0.143 and the Clutch gear is engaged with the Clutch
lock tooth as above Step2’s center figure.
3.
When the ASF motor rotates CW direction in the above Step3’s figure, the Change
lever moves to the right direction with the CW rotation of the Combination gear
37.6, 44.4. And the drive from the PF motor is transmitted to the LD roller shaft
via Clutch gear and Clutch lock tooth.
4.
The LD roller shaft rotates about 360 degree and the Change lever push the Clutch
lever and the ASF motor drive is interrupted. This position is the ASF home
position.
Paper Return Plate (Pad holder)
Unlike the previous products, The Paper return plate is built in the ASF frame
instead of the Paper return lever. The Paper separation pad is also stacked on the
plate.
It works with the spring force of the Torsion spring 25.7 (mounted in the ASF
frame) as following figure.
