Description
Technical field
The utility model relates to image processing system, relates in particular to the actuating unit in the image processing system.
Background technology
The image forming apparatus of electro photography such as laser printer are a kind of electrofax principles of utilizing, and through overcharging, exposure is developed at least, transfer printing, and fixing forms the equipment that forms image on medium such as the paper at image.
In charging process,, utilize as the corona discharge mode evenly predetermined electric charge is filled with in the surface of photosensitive components such as photo-sensitive cell by charging device; In exposure, the photosensitive member surface of filling even predetermined charge with is carried out optionally exposure, by the place of exposure, because the light sensitive characteristic of photo-sensitive cell, resistance descends, so by the electric charge ground connection cancellation in the localities of exposure, promptly after the exposure, photosensitive member surface forms an electrostatic latent image that distribution characterized by electric charge corresponding to institute's desire formation image; At developing process, by developing parts, developer that is used to form visual image such as carbon dust, the effect of mating reaction power such as electric field force is delivered on the electrostatic latent image of photosensitive member surface, and it is visual to make that above-mentioned electrostatic latent image obtains; In transfer process,, as transfer roll the developer on the photosensitive member surface electrostatic latent image is transferred to image and form on medium such as the paper by transfer device; At fixing, the developer of transferring on the image formation medium is secured on the image formation medium by fixing device.
The Poewr transmission mechanism of printer is that photo-sensitive cell can be provided with from the driving force that the printer driver head is accepted to rotate, to have a kind of be such to the Poewr transmission mechanism of printer in the prior art: photo-sensitive cell power is subjected to mouth to be provided with the spirality projection, and the printer driver head is provided with spiral groove, Poewr transmission mechanism is realized the transmission of revolving force by the spirality projection and the engagement of groove, thereby make photo-sensitive cell work, but to drive the torque ratio that power will produce by mouth bigger for the printer driver head in this Poewr transmission mechanism, and driving head and power are subjected to the engagement of mouth also to have certain limitation.
The driving head control gear of printer is that a controlling and driving axial stretching and photo-sensitive cell power are subjected to mouthful engagement and are provided with, it is to describe like this that a kind of flexible method of printer driver head of controlling is arranged in the prior art: in the process that opens or closes printer cover door, the cover door is controlled a rotary body by a connecting rod, there is an inclined-plane to control the retraction of printer driver head by rotation on the rotary body, the printer driver head is subjected to the recovery of elasticity after a spring is compressed to control it to eject, and then reach disengaging and the engagement that is subjected to mouthful with photo-sensitive cell power, this printer is realized by mechanism (rotary body inclined-plane) fully to the ejection of printer driving head and the control of retraction. this control gear mechanism more complicated, and transmission is stable inadequately, occurs making printer driver head and photo-sensitive cell power to be subjected to mouthful unsettled phenomenon of engagement easily.
The utility model content
The utility model provides a kind of printer, and is stable inadequately to solve existing printer control gear mechanism complexity, transmission, makes printer driver head and photo-sensitive cell power be subjected to mouthful unsettled defective of engagement easily.
In order to solve above technical matters, the technical scheme that the utility model adopted is:
A kind of printer, the control gear that comprises a printer driver head and a control printer driver axial stretching, it is characterized in that described extension and contraction control mechanism comprises: the battery valve of contactor, connecting circuit switch is connected the driving lever that the battery valve other end connects driving head with an end.
Described battery valve is provided with flexible member, and described flexible member is between battery valve and driving lever.
Described driving head is provided with flexible member and driven wheel, and described flexible member is between described driven wheel and described driving lever.
Described driven wheel is provided with gearset spacer.
Described driving head is provided with key, and described driven wheel is provided with the keyway of admitting described driving head key.
One end of described driving head is provided with the groove of admitting described driving lever.
After having adopted technique scheme, because the battery valve of extension and contraction control mechanism is by the telescopic moving of driving lever controlling and driving head, thereby engagement or disengaging that controlling and driving head and power are subjected to mouthful make power be subjected to the simple in structure of mouth and printer driver head, be easy to realize, and power transmission is stable.It is stable inadequately to have solved existing printer control gear mechanism complexity, transmission, makes printer driver head and photo-sensitive cell power be subjected to mouthful to mesh a unsettled technical matters easily.
