Dynamic, push rod 5 drives seal member 4 mobile and opens meal outlet 221,7 forced compression of spring.
Meanwhile the first guide surface 334 of rotary force reception tooth 33 is abutted with rotary drive 101, rotary force receives tooth 33
It is rotated under the action of 101 deboost of rotary drive around hinged shaft 332, engaging section 331 is to close to rotary force transmitting head 31
The direction of axis L rotates, i.e., rotates along direction shown in arrow R2 in Fig. 9, and rotary force receives tooth 33 and turns to disengaging configuration,
32 stress of torsional spring is in compressive state, until carbon dust container is moved to coupled position.
Then, continue to push carbon dust container forward, the rotary force of two of them diametrically receives the engaging section 331 of tooth 33
It is moved to 103 position of engaging hole of rotary drive 101, and drives rotary force under the action of the elastic restoring force of torsional spring 32
It receives tooth 33 to rotate backward around hinged shaft 332, engaging section 331 is rotated to the direction of the axis L far from rotary force transmitting head 31, i.e. edge
The rotation of direction shown in arrow R1 in Fig. 7, rotary force receive tooth 33 turn to behind the position of engagement with rotary drive 101
It connects.
Then, rotary drive 101 drives rotary force to receive tooth 33, to drive rotation force transfer unit 3 to far from appearance
The direction of device main body 1 moves a certain distance, since rotary drive 101 needs to retreat, to avoid rotary force from receiving tooth 33
Deviate from from engaging hole 103 in 101 fallback procedures of rotary drive, needs the torsional spring 32 for selecting that there is larger torsion.
Finally, carbon dust container completes installation, rotary drive 101 drives carbon dust container to rotate and supplies into imaging device
Powder.
The removing method of carbon dust container includes the following steps.
Firstly, the driving direction along rotary drive 101 rotates carbon dust container, driving direction, that is, rotary drive 101
Tooth 33 is received to rotary force and applies clockwise direction shown in arrow R3 in the direction namely Fig. 7 of active force, is pulled out simultaneously
Carbon dust container, the second guide surface 335 are abutted with the side wall of engaging hole 103, and it is reversed in the second guide surface 335 that rotary force receives tooth 33
It is rotated under the action of thrust around hinged shaft 332, engaging section 331 is rotated to the direction of the axis L close to rotary force transmitting head 31, i.e. edge
The rotation of direction shown in arrow R2 in Fig. 9, rotary force receive tooth 33 and turn to disengaging configuration.
Then, continue to pull out carbon dust container, until taking out carbon dust container.
