4) L
1the time, only need make flexible member 7 deflection (L in the axial direction
2-L
3) be slightly larger than (L
5-L
4) get final product, now need the reverse or forward along former detection of gear sense of rotation, detection of gear 2 is rotated to the top of initial position, then loose one's grip and can automatically reset.After the detection of gear reseting procedure of the present embodiment guarantees production test, powder box can be detected the realization counting again, resets easy simultaneously.
As shown in Figure 9, detection of gear 2 also can comprise two projections, a projection is that detection piece 23 is for triggering the information testing agency of image processing system, the handle 27 that another projection is only mentioned detection of gear 2 when resetting, avoid the detection piece 23 that fractures in reseting procedure, handle 27 height in the axial direction is less than the height of detection piece 23, and projection quantity also can be more than two certainly.
In the present embodiment, detection of gear also can snap fit onto and install on pin by buckle, buckle elastic deformation in the detection of gear installation process, detection of gear is installed to and installs on pin, the keeper of this programme is for installing pin, the buckle that flexible member is elastically deformable, buckle can be made into integration or be made into integration with detection of gear with the installation pin; During the reset detection gear, only need overcome the buckle constraining force and can make detection of gear move axially.

As shown in Figure 10 a and Figure 10 b, the present embodiment and embodiment mono-difference are flexible member 7 is arranged between sidewall 11 and detection of gear 2, and flexible member 7 one ends and sidewall 11 butts, the other end and detection of gear 2 are near the end face butt of sidewall 11.The first block comprises the extension radially extended along detection of gear 2, and when detection of gear 2 is positioned at last position, the extension 101a of spacing preiection 24 and the first block 101 interferes, thus restrict detect gear 2; Similarly, the second block comprises the extension radially extended along detection of gear 2, and when detection of gear 2 is positioned at initial position, the extension of positioning convex and the second block is interfered; The first block and the second block all comprise the extension radially extended.When detection of gear 2 is positioned at last position, the extension 101a of spacing preiection 24 and the first block 101 interferes, the extension that the block in embodiment mono-does not extend diametrically, and block only extends axially along detection of gear 2, and to outstanding away from sidewall; If block does not have extension radially, in the process of reset detection gear 2, when after direction N pressing detection gear 2, spacing preiection 24 is interfered with the first block 101 always, thereby can not be along former detection of gear 2 sense of rotation A(counterclockwise) spinning reduction, during therefore along sense of rotation A spinning reduction, block must have radially extension; The first block 101 and the second stop block structure are similar; When detection of gear 2 during in last position, in the process of reset detection gear 2 after direction N pressing detection gear 2, spacing preiection 24 is not interfered with the extension 101a of the first block, thereby at sense of rotation restrict detect gear 2 no longer, be provided with the first gap that spacing preiection 24 passes through between the first link stopper 101 and sidewall, agitating element gear 66 also is provided with towards the gear face of sidewall 11 and the spacing of sidewall 11 the second gap that spacing preiection 24 passes through simultaneously; When detection of gear 2 is moved to sidewall along installation pin 14 under external force, along in the process of sense of rotation A rotation detection of gear 2, spacing preiection 24 passes through from described two gaps; The axial spacing of described extension 101a and sidewall 11 is the first gap that spacing preiection 24 passes through; In detection of gear 2, by two gaps, arrive initial positions below after, remove external force, detection of gear can automatically reset.Spacing preiection 24 is corresponding the reducing of axial length of detection of gear 2, be convenient in the process of reset detection gear 2 move axially less apart from the time, the first extension 101a of spacing preiection 24 and the first block 101 breaks away from and interferes.
In the present embodiment, spacing preiection 24 has radially extension with respect to the gear parts of detection of gear 2, the tooth radius that is detection of gear 2 is less than the distance of spacing preiection 24 ends to detection of gear 20 axis, therefore during reset detection gear 2, spacing preiection 24 need pass through from the gap of the gap of agitating element gear 66 and sidewall 11 and extension 101a and sidewall 11; When the spacing preiection end, to the distance of detection of gear 20 axis while being less than the tooth radius of detection of gear 2, the extension that spacing preiection only need be by the first block gets final product to the gap of sidewall.
In the present embodiment, the first block also can adopt the structure identical with block in embodiment mono-with the second block, there is no extension radially; Detection of gear is being reset to the process of initial position from last position, when needing to guarantee the axially close sidewall of detection of gear and turning clockwise detection of gear, detection of gear and agitating element gear do not mesh, be that detection of gear 2 and agitating element gear 66 stagger on detection of gear 2 is axial, while guaranteeing to turn clockwise detection of gear, the second block is not interfered with spacing preiection simultaneously.
When detection of gear is positioned at last position in sum, the limited structural limitations of detection of gear is in last position, when detection of gear during in last position, detection of gear under external force can be axially near sidewall, thereby avoid position limiting structure or agitating element gear, make detection of gear can clockwise or be rotated counterclockwise the below that arrives initial position, finally under the effect of flexible member, detection of gear axially arrives initial position away from sidewall, moving axially of last position probing gear, be in order to make detection of gear can continue rotation, and (position limiting structure or the agitating element gear) top to initial position that clears the jumps.
