Fig. 4, Fig. 4 are the exploded views of stylus mechanism 4, and stylus mechanism 4 has fix bar 41, pedestal 42, two contact pilotages 43, guide rod 44, bullets
Spring 45 and guard member 46.The fixing end of guide rod 45 is fixedly installed on baffle plate 3, and spring 45 is enclosed on guide rod 45, with cuboid
Axis of the guard member 46 of structure along guide rod 45 penetratingly opens up guide hole 461, is axially offered along guide hole in the top of guide hole 461
Groove 462.Groove 462 has the first opening and the second opening, and the first opening is arranged on guard member 46 towards the end face of powder box 2
On 463, the second opening is arranged on the end face 464 of the radial direction of guide hole 461, and the first opening is conjointly set with the second opening, and the
One opening constitutes the opening in the present embodiment with the second opening.
Reference picture 5, Fig. 5 is the sectional view of groove 462 in guide hole radially, and groove 462 has in the axial direction of guide hole 461
Bottom wall 465, has side wall 466 in the both sides of bottom wall 465, and elastomeric cleaning members 467 are separately installed with the side wall 466 of both sides,
Elastomeric cleaning members 467 can be made by the elastic component such as sponge or rubber.Guard member 46 is sleeved on guide rod 45 by guide hole 461
On, the first end of spring 44 is abutted with guard member 46, and the second end of spring 44 is abutted with baffle plate 3.
Reference picture 6 simultaneously combines Fig. 3, and Fig. 6 is the structure chart of fix bar 41, pedestal 42 and contact pilotage 43.The first of fix bar 41
Fixing end is fixedly installed on baffle plate 3, and the second fixing end of fix bar 41 is fixedly connected on pedestal 42.Pedestal 42 is arranged on powder box
The circuit board and two contact pilotages 43 for having laser printer can be set during 2 installation on the corresponding position of consumable chip 26, on pedestal 42,
Two contact pilotages 43 are electrically connected with the circuit board, and the circuit board be can also install into outside pedestal 42, and contact pilotage 43 is connected to by wire
Between circuit board.Contact pilotage 43 is the metallic conductor that sheet metal is made, and contact pilotage 43 includes fixed part 431 and electrical connection section
432, fixed part 431 is extending axially outward form electrical connection section 432 along guide hole 461.Contact pilotage 43 passes through the first opening or second
During opening is installed to 462 in groove, contact pilotage 43 is abutted and is interference fitted with the elastomeric cleaning members 467 of both sides, the fixation of contact pilotage 43
Portion 431 is abutted (referring to Fig. 5) with bottom wall 465.
Reference picture 7, Fig. 7 is the schematic diagram before consumable chip 26 and the connection of stylus mechanism 4.It is located at contact pilotage 43 in the axial direction
Sectional view.As seen from Figure 6, contact pilotage 43 is due in groove 462, and contact pilotage 43 is clamped by the elastomeric cleaning members 467 of both sides,
So being located at, contact pilotage 43 is not susceptible to external force in groove 462 or other objects are collided, while being also not readily susceptible to laser printing
Useless powder in machine is polluted.
When X is installed to powder box installation to powder box 2 in assembly direction, the housing of waste powder hopper 23 and the end face 463 of guard member 46
It is adjacent, and as powder box 2 continues the installation toward X-direction, guard member 46 will be slided along guide rod 45 towards X-direction.
Reference picture 8, Fig. 8 is the schematic diagram after consumable chip 26 and the connection of stylus mechanism 4.It is located at contact pilotage 43 in the axial direction
Sectional view.Guard member 46 will be slided along guide rod 45 towards X-direction at any time, because pedestal 42 is relatively fixed on baffle plate 3,
So contact pilotage 43 will be relatively moved with groove 462, the electrical connection section 432 of contact pilotage 43 is reached outside groove 462 from opening, and
Electrically connected with the electric contact of consumable chip 26.Then realize that consumable chip 26 is exchanged with the information of circuit board.
When opposite direction in X direction takes out powder box 2, in the presence of the elastic restoring force of spring 44, by guard member
46 opposite direction in X direction is pushed, and guard member 46 is returned to position as shown in Figure 6.Because contact pilotage 43 is bounced back by opening
Into groove, so with contact pilotage 43 relative slip occurs for the elastomeric cleaning members of both sides, then elastomeric cleaning members can be on contact pilotage 43
Pollutant cleaned, be conducive to improving the stability electrically connected next time.
Therefore, protected by the way that contact pilotage 43 is arranged in groove 462, be conducive to avoiding by external force or other
Object is collided, while when the housing of powder box is installed in powder box installation position, the housing of powder box 2 will be contacted with guard member 46,
And slide guard member 46 along guide rod with the installation of powder box, then cause groove 462 also to be moved along the axial direction of guide rod
It is dynamic, so that contact pilotage 43 electric contact of the exposed consumable chip 26 with powder box can be electrically connected at opening.Because contact pilotage 43 will
Supported by groove 462 and the chucking power of elastomeric cleaning members 467, so as to improve stability of the contact pilotage 43 when being engaged, it is to avoid
Deform or be broken when with contact, then improve the durability and stability of stylus mechanism.
Certainly, guide rod 45 is as the locating part in the present embodiment in above-described embodiment, by the locating part to guard member
Guide hole coordinates, the mobile limitation to guard member of realization so that guard member can be moved along locating part.Can also have during practical application
It is more to change, for example specifically, the fixing end of raised line can be fixedly installed on powder box installation position using raised line as locating part
On, and chute is opened up in guard member, by the way that chute is linked on raised line so that the guard member with chute can be along convex
Bar is slided, and realizes that contact pilotage is exposed from groove, while can be achieved on the purpose of the present invention.
