5,11-6,11-7 are transmitted on useless powder cleaning roller 11-8, and useless powder cleaning roller 11-8 is contacted with transfer unit pressure roll 6-5 by useless powder
It cleans out.
To make motor commutation not influence the direction of rotation of paper commutation tray unit 10, toner cartridge gear unit 9, transfer transmission
It is respectively equipped with unidirectional transmission in unit 6 and waste powder hopper gear unit 11.To be set to input gear in toner cartridge gear unit 9
For unidirectional transmission on 9-1, input gear 9-2, unidirectional transmission includes riveting axis, and driving tooth is cased with successively on riveting axis
Take turns 9-2-1, chisel teeth set 9-2-2, driven gear 9-2-3, spring 9-2-4 and photosensitive drums driving claw 9-2-5, driving gear 9-2-
It is provided with the first chisel teeth on 1, in the upper surface setting that chisel teeth covers 9-2-2 there are two grabbing outside, is grabbed and chisel teeth set outside two
The upper surface of 9-2-2 is vertical, and arc convex body is provided between being grabbed outside two, and the lower surface that 9-2-2 is covered in chisel teeth is provided with
Second chisel teeth, the first chisel teeth are meshed with the second chisel teeth, and muscle is provided on driven gear 9-2-3, grab connect with muscle outside
It touches.
When motor rotates forward, the gear in main transmission unit 1 is engaged with the tooth form of driving gear 9-2-1, makes its rotation,
Under the action of frictional force, chisel teeth set 9-2-2 has to be rotated clockwise therewith, and the arc on chisel teeth set 9-2-2 is convex
Body is contacted with the muscle on driven gear 9-2-3, and the tooth form of driven gear 9-2-3 is engaged with photosensitive drums driving claw 9-2-5, load
It is larger, so chisel teeth covers 9-2-2 and can arc convex body along riveting axis axis by the top rib on driven gear 9-2-3 in rotary course
To movement (to the direction close to the first chisel teeth), the first chisel teeth and chisel teeth set of driving gear 9-2-1 are allowed in this way
The second wedge-shaped tooth engagement of 9-2-2, then driving gear 9-2-1 be meshed power by the first chisel teeth and the second chisel teeth
Chisel teeth set 9-2-2 is passed to, chisel teeth set 9-2-2 transmits power by grabbing to contact with the muscle of driven gear 9-2-3 outside
Past, so driven gear 9-2-3 drives photosensitive drums driving claw 9-2-5 to rotate clockwise when driving gear rotates clockwise.
When motor inverts, the gear in main transmission unit 1 is engaged with the tooth form of driving gear 9-2-1, makes its rotation,
Under the effect of the component of first chisel teeth and the second chisel teeth engagement force, chisel teeth covers 9-2-2 can be along riveting axis axis in rotary course
To movement (far from the first chisel teeth direction), the first chisel teeth and chisel teeth that allow for driving gear 9-2-1 in this way cover 9-2-2
The second chisel teeth be disengaged from, driven gear 9-2-3 can not obtain power, so when driving gear 9-2-1 rotates counterclockwise
Driven gear 9-2-3 and photosensitive drums driving claw 9-2-5 do not rotate, and achieve the purpose that single-direction transmission.
In order to realize that printer two-sided functional devises three vital points, first, unidirectional transmission at three is devised, point
It is not photosensitive drums, transfer, at waste powder hopper transmission, motor controls this gear at three and stops rotating when inverting；Second is that at fixing
Increase motor, when the reversion of the motor of main transmission unit 1, the gear direction of rotation at fixing is unaffected.In addition, in printer
The motor rotation at fixing can be directly controlled when booting preheating, do not have to, by 1 motor passing power of main transmission unit, save energy
Source facilitates control；It is automatically redirected transmission device 10 between paper feeding component 4 and paper commutation tray unit 10 third, devising,
Ensure no matter motor is rotated forward or inverted, and the direction of rotation of paper commutation tray unit 10 is constant always.
This power transfer mechanism is applied in auto double color duplex printer, and when double-colored duplex printing controls main biography first
Dynamic motor rotates in the forward direction, and control takes paper relay 2-4 to take paper and prints verso content, and paper passes through laser scanning, transfer, calmly
After shadow unit, control motor reversely rotates when will be disengaged from two level feeding-in roll shortly so that paper is retracted and commutated by paper and held in the palm
Disk unit 10, control motor rotates in the forward direction after paper completely disengages two level feeding-in roll, and prints odd page content.In print procedure
Photosensitive drums, transfer belt 6-1, waste powder hopper pallet can not be overturn when the reversion of middle design motor, thus in main transmission unit 1 pair with
Its meshed gears has carried out single-direction transmission design so that stops not turning when motor reversely rotates.Similarly in order to change heating roller
The directions when motor inverts 8-6 do not change, and fixing gear unit 8 increases the direction that motor controls gear rotation at any time.
One embodiment of the present invention has been described in detail above, but the content be only the present invention preferable implementation
Example should not be construed as limiting the practical range of the present invention.It is all according to all the changes and improvements made by the present patent application range
Deng should all still fall within the scope of the patent of the present invention.
