(2) Up/down movement of the image drum unit and rotation of the image drum.
The up/down movement of the image drum unit and the rotation of the image drum are
performed by a mechanism shown below. (See Figure 2.6-a). This mechanism is driven by a
single pulse motor.
When the pulse motor turns left (Counter-clockwise), the up/down gear turns left (in the direction
of "a"), and the up/down lever (see Figure 2.6-b) moves up (in the direction of "a". The up/down
lever pushes up the up/down actuator of the image drum unit. The image drum unit moves up as
shown in Figure 2.6-b). The image drum rotates freely.
When the pulse motor (see Figure 2.6-a) turns right (Counter-clockwise), the image drum gear
turns left (Counter-clockwise) and the up/down gear (one-way gear) is released. The weight of
the image drum unit is applied to the up/down lever via the up/down actuator of the image drum
unit. The free up/down gear turns right (in the direction "b" in Figure 2.6-a), and the image drum
unit goes down until the up/down actuator of the image drum unit is stopped by the up/down
lever. (See Figure 2.6-c). During this, the image is transferred onto the running paper.
