The extending direction of two groove 61b2 is slided in second direction.By above structure, driving force receiving portions 61a can be relative to powder feeding roller
4 move on a direction with the Axis Cross of powder feeding roller 4, and even if same not with powder feeding roller 4 in power reception part 61a
It can also be transferred a driving force in powder feeding roller when axis.
As shown in Figure 9 and Figure 10, maintaining part 8201 is provided in the present embodiment at second bearing portion 8201, works as handle box
It does not install in imaging device, maintaining part 8201 keeps the power reception part 61a1 of second shaft coupling 61 to be in second bearing
The top in portion 8201, and the axis runout of the axis of power reception part 61a1 and powder feeding roller 4, specifically power
The level height of the axis of receiving portion 61a1 is higher than the level height of powder feeding roller 4, which is arranged so as to work as handle box
It installs in imaging device, power reception part 61a1 can be engaged smoothly with the second driving head.Holding member 8201 is set as
Second bearing portion 8201 extend elastic piece, when closing machine door closure 100, handle box A is lifted, power reception part 61a with
The engagement of second driving head keeps not moving, and the second frame 2 is then lifted, and power reception part 61a1 will overcome maintaining part 8202
Elastic force and be moved to the lower part of bearing portion 8201.After the second frame is raised to predetermined position, power reception part 61a
Axis will be substantially coaxial with the axis of powder feeding roller 4, powder feeding roller 4 is transferred to the stable driving force by the second driving head
In.When handle box, which encounters imaging problem, to be needed to take out, machine door closure 100 is opened, handle box is moved down at this time, the second frame 2
Also move down, but power reception part 61a1 still with the second driving head holding engage, power reception part 61a1 but from newly from
The lower part in second bearing portion 8201 is moved to top and maintained portion 8202 is located in top.In other words, by power reception portion
Dividing 61a1 to be arranged to can be mobile relative to the second frame when by external force, and can be mobile relative to maintaining part, that is, can reach
The power reception part 61a1 of second shaft coupling can with the second driving head in imaging device when above-mentioned handle box installation and taking-up
With the technical effect being disengaged from smoothly engaged.
Embodiment 4
It as shown in figure 11, is the structural schematic diagram of embodiment 4 provided by the utility model, the present embodiment and embodiment 3
It the difference is that only, maintaining part 8203 does not need the structure for being arranged to elasticity, it is only necessary to which maintaining part 8203 is arranged along axis
