Present embodiment can also be, reference column 35d is arranged on the developing cell housing rear wall 10a, and the end of flexible member 34a is fixed on the developing cell housing 10a by reference column 35d, and the other end contacts with gland 35.
Embodiment nine:
As shown in figure 15, by the 9th kind of the utility model the side sectional view of employing embodiment handle box.Except that specified otherwise, the handle box structure that present embodiment adopted is identical with handle box structure shown in Figure 12.
As seen from the figure, gland 35 is provided with fore-set 35a; Gland 36 is provided with reference column 36c, and flexible member 34 can be fixed on the reference column 36c.When gland 35 and gland 36 are pivoted when being closed condition by open mode, the fore-set 35a on the gland 35 contact with developing cell housing rear wall 10a, limits the mobile backward of developing cell 1; After flexible member 34 is fixed on the gland 36, in the process that reference column 36 is closed, one end of flexible member 34 contacts with the photosensitive unit housing antetheca 31a of photosensitive unit 2, and for photosensitive unit 2 provides an elastic force, photo-sensitive cell 21 is moved to the direction of developing element 11.
With embodiment seven similarly, present embodiment can also be: on gland 35 and the gland 36 fore-set is set all, perhaps on gland 35 and the gland 36 flexible member is set all, make developing element 11 and photo-sensitive cell 21 close.
All execute the handle box structure that adopted of example the utility model, also can be used as make developing element and photo-sensitive cell mutually near and discontiguous situation.
