Embodiment
Reference picture 5, drive assembly of photosensitive drum of the invention include driving wheel 1, driving locating support 2 and spring 3, driving wheel
1 is arranged at the end of photosensitive drums 4, is fixed with the phase of photosensitive drums 4, drives photosensitive drums 4 to rotate when driving wheel 1 rotates.Driving positioning branch
Frame 2 is arranged in driving wheel 1, and spring 3 is arranged between photosensitive drums 4 and driving locating support 2, and driving is supported in one end of spring 3
Locating support 2, makes it be close to driving wheel 1, and the other end supports the end of photosensitive drums 4.
In combination with Fig. 6 a to Fig. 6 c, the driving assembling for being engaged with printer driver section is provided with driving wheel 1
Groove 1a, when cartridge is installed on printer, printer driver section is stretched into driving fitting recess 1a, drives fitting recess 1a inwalls
Department of assembly 1b is provided with, department of assembly 1b is in contact with printer driver section, and power when printer driver section is rotated passes to drive
Driving wheel, rotate driving wheel.A pair of through hole 1c (Fig. 8) are provided with driving fitting recess 1a bottom surfaces, through hole 1c is located at department of assembly
On the inside of 1b (side that will be close to axis is defined as inner side).The side relative with driving fitting recess 1a of driving wheel 1 is photosensitive drums
Fitting recess 1d, for coordinating with photosensitive drums 4.As shown in Fig. 7 a to Fig. 7 c, driving locating support include rack body 2-1, a pair
The support department 2-2 stretched out upwards from rack body 2-1, drives the vertical section shape of locating support to take the shape of the letter U.Support department
2-2 size and the size of the through hole 1c on driving fitting recess 1a bottom surfaces are adapted.
As shown in figure 8, driving wheel 1 is tight with the end of photosensitive drums 4, driving locating support is arranged at the photosensitive drums of driving wheel 1
In fitting recess (non-label), the support department 2-2 of locating support is driven to be extend out to from through hole 1c in driving fitting recess 1a, support
Body 2-1 is located in photosensitive drums fitting recess, and spring 3 is arranged between the end of photosensitive drums 4 and driving locating support, and spring 3 is supported
Driving locating support.When coordinating with large-sized printer driver section 5, printer driver section 5 stretches into driving fitting recess 1a
In, while locating support will be driven to make it overcome the elastic force of spring 3 to be moved rearwards, until support department 2-2 is released to internal pressure
