Problems solved by technology

However, due to the combined error caused by the aging of the torsion spring and the resistance of the toner, the time value for the light transmission window on the code wheel to pass through the code detection unit has uncertainty and changes within the error range, which will affect the image processing box. Accuracy of state identifying information

Embodiment 1

[0028] Embodiment 1: an image processing box using a cam slider device

[0029] figure 1 The shown developing unit 1 mainly includes an agitator shaft 5 supported on both side walls of the developing unit 1 , a powder bin 2 containing toner inside, and an assembly 18 installed outside the side wall of the developing unit 1 .

[0030] figure 2 , image 3 The photosensitive drum cartridge 17 shown mainly includes a waste toner bin 6, a slider cover sheet assembly 19, a spring 9, and a side wall 7 for assembling the slide block cover sheet assembly, wherein the wall 7 includes a rectangular window-shaped Slider track 8 has a support block 13 perpendicular to the inner wall surface on the inner wall surface of wall 7, and a cylindrical protrusion 14 is used for bearing spring 9 on one side of 13. From two perspective views in different directions, it can be seen that the installed slider block assembly 19 is installed on the side wall 7 of the photosensitive drum cartridge 17 ...

Embodiment 2

[0038] Embodiment 2: Image processing box adopting rack and pinion device

[0039] Figure 11 , Figure 12 As shown, the gear assembly 23 is integrally formed, including a half-key hole 20 for matching the shaft of the stirring rack in the developing unit, a driving gear 21 for driving the shaft of the stirring rack to rotate, and a sector gear 22, wherein the sector The gear angle β determines the opening time of the shutter 26 in the rack-slider assembly 27 at the position of the code reader.

[0040] The slider assembly 27 is integrally formed, including an opaque shielding sheet 26, a cylindrical projection 25 perpendicular to the plane of the shielding sheet 26 for connecting springs (not shown), a slide block 40, and a slide block 40 There is a flange above and below respectively, which is used for the positioning of the slider 40 in the track, so as to prevent it from slipping out of the assembly track. The slider track and the spring connection supporting member match...

Embodiment 3

[0041] Embodiment 3: Image processing box adopting slider crank device

[0042] Figure 13 The shown crank assembly 30 is integrally formed, and it includes a half-key hole 28 for matching the shaft of the stirring rack in the developing unit, a driving gear 39 for driving the shaft of the stirring rack to rotate, and a drive gear 39 on the outer surface of the driving gear 39. The shaft 29 is extended.

[0043] Figure 14 The slider assembly 37 shown includes an opaque mask 36 , a shaft 35 extending perpendicular to the plane of the mask, and a slider 38 . Wherein, there is a flange respectively above and below the slide block 38, which is used for the positioning of the slide block in the track, so as to prevent it from slipping out of the assembly track. The slider track matched with the slider assembly 37 is also located on one side wall of the photosensitive drum cartridge casing, and will not be described here.

[0044] Figure 15 The connecting rod 33 shown include...

Abstract

The invention relates to an image processing box in an electronic photograph imaging machine, which comprises a developing unit, a photosensitive drum box and an encoding device for transmitting state identifying information to the electronic photograph imaging machine, wherein the photosensitive drum box and the developing unit are assembled detachably; and the encoding device is formed by a plane mechanism, and a signal barrier sheet in the encoding device makes linear reciprocating motion under the rotating action of a driving gear. As the technical scheme is adopted by the invention, a plane mechanism device is adopted in the encoding device, and the motion trails of the components have high accuracy, so the detection time that the non-transparent barrier sheet passes through a code reader within set time is more accurate, and compared with an encoding wheel device driven by a torsional spring coupling device, the image processing box always can be identified correctly and can be operated effectively.

Description

technical field [0001] The invention relates to an image processing box in an electrophotographic imaging machine. Background technique [0002] The electrophotographic imaging machine converts the text and graphic information into a laser beam, and then scans the photosensitive drum at a constant speed along the axis of the photosensitive drum through a series of optical systems, thereby forming an electrostatic latent image corresponding to the input information on the photosensitive drum. After a series of actions, it is transferred to the electrostatic latent image to form a visible image, and the visible image of the developer formed on the photosensitive drum is finally transferred and fixed on the recording medium. [0003] After many times of use, electrophotographic imaging machines need to carry out various maintenance work, such as replacing the photosensitive drum, replenishing the developer, adjusting the charging element, cleaning the waste toner container, etc...
