First and second columnar portion 133 and 134 are interconnected with one another, and are formed with spirality projection 135a within it on the circumferential surface.When powder box 130 rotated, by the motion of the spirality projection 135a on developer bottle 131 inner circumferential surfaces, the ink powder in the developer bottle 131 was carried towards opening 134a.In addition, on outside surface, be formed with spiral slot 135b corresponding to the developer bottle 131 of spirality projection 135a.
Fig. 5 shows the viewgraph of cross-section according to the composition of the bottle cap 132 of same embodiment.As shown in Figure 5, bottle cap 132 is made up of flange part 136 and follower 137.Flange part 136 is a bowl-type, and the end that holds second columnar portion 134 in inside.The flange part 136 and second columnar portion 134 are fixed by screw thread.
In addition, the internal diameter of flange part 136 is greater than the external diameter of second columnar portion 134.Therefore, between the external peripheral surface and flange part 136 inner circumferential surfaces of second columnar portion 134, as shown in Figure 4, be formed with the clearance G that wherein contains air.
In addition, as shown in figure 11, on flange part 136 external peripheral surfaces, form effigurate jut 136a according to Machine Type or purposes.Jut 136a rotates with powder box 130, and when the detector 170 faced as shown in Figure 3, pushes the button of detector 170.
Therefore, when product that powder box 130 meets for type, the concavo-convex 152a that is formed on the concavo-convex 137a on the follower 137 and is formed on the unitor 152 of powder box actuator 150 cooperates each other well, and powder box 130 remains on the tram of powder box keeper 140.
On the contrary, when product that powder box 130 closes for type mismatch, be formed on the concavo-convex 137a on the follower 137 and the concavo-convex 152a that is formed on the unitor 152 of powder box actuator 150 mismatches each other, powder box 130 is outstanding from powder box keeper 140.
(slot part 139)
Below, slot part 139 will be described.As shown in Figure 4, the external diameter of supposing first columnar portion 133 is D1, and the external diameter of second columnar portion 134 is D2, and the external diameter of flange part 136 is D3, and the relation between D1, D2 and the D3 is as follows:
D1＞D2 and D3＞D2.
In other words, the diameter of second columnar portion 134 is less than first columnar portion 133 that is separately positioned on its both sides and the diameter of flange part 136.Therefore, on the external peripheral surface of powder box 130, between first columnar portion 133 and flange part 136, be formed with circular slot part 139.Slot part 139 is limited by first columnar portion 133, second columnar portion 134 and flange part 136.Therefore, by the outer diameter D 1 that makes up first columnar portion 133, the outer diameter D 2 of second columnar portion 134 and the outer diameter D 3 of flange part 136, can form the slot part 139 of different shape.
(identification key 190)
(relation between slot part 139 and the identification key 190)
Below, with the relation of describing between slot part 139 and the identification key 190.The projecting plate 192 that Fig. 7 shows the identification key 190 of the same embodiment according to the present invention enters the planimetric map of the state of powder box 130 slot parts 139, and the projecting plate 192 that Fig. 8 shows the identification key 190 of the same embodiment according to the present invention enters the skeleton view of the state of powder box 130 slot parts 139.
Suppose that the distance from the inside surface of loam cake 107 to the leading section of projecting plate 192 is L0, distance from the inside surface of loam cake 107 to first columnar portion, 133 external peripheral surfaces is L1, distance from the inside surface of loam cake 107 to second columnar portion, 134 external peripheral surfaces is L2, and the distance from the inside surface of loam cake 107 to flange part 136 external peripheral surfaces is L3, and L0 is as follows to the relation between the L3:
L1＜L0＜L2 and L3＜L0＜L2.
Therefore, shown in Fig. 7 and 8, if be installed in the product that the powder box 130 in the main frame body unit 100 meets for type, when loam cake 107 was closed, the projecting plate 192 of identification key 190 entered the slot part 139 of powder box 130.
Yet if the powder box 130 that is installed in the main frame body unit 100 does not have slot part 139, in the process of loam cake 107 near the opening 106 of main frame body housing 101, powder box 130 and projecting plate 192 can be interfered each other, and can't close loam cake 107 ideally.
In addition, even powder box 130 has slot part 139, unless the position of slot part 139 is corresponding to the position of the projecting plate 192 of identification key 190, otherwise, in the process of loam cake 107 near the opening 106 of main frame body housing 101, powder box 130 still can be interfered each other with projecting plate 192, and loam cake 107 equally also can't be closed ideally.
In addition, for instance, when the position of slot part 139 is not corresponding with the position of projecting plate 192, for example, the concavo-convex 137a that is formed on the follower 137 is not corresponding with the concavo-convex 152a on being formed on unitor 152, and therefore, follower 137 can't fully be inserted in the unitor 152.
That is to say, even the powder box of being installed 130 has identical shaped and slot part 139 same position with the powder box that type meets, unless the concavo-convex 137a of follower 137 and the concavo-convex 152a of unitor 152 can be corresponding mutually well, otherwise loam cake 107 still can't be closed.
In addition, when slot part 139 mistakes are shallow, even powder box 130 has slot part 139, and the position of the slot part 139 of powder box 130 is corresponding with the position of the projecting plate 192 of identification key 190, that is, when the outer diameter D 2 of second columnar portion 134 is excessive, in the process of loam cake 107 near the opening 106 of main frame body housing 101, powder box 130 and projecting plate 192 can be interfered mutually, and loam cake 107 can't be closed ideally.
(operation of this embodiment)
On the inside surface of the loam cake 107 of this embodiment, depending on the position of electrophotographic copier type and purposes that be provided with projecting plate 192, its length depends on Machine Type and purposes.
Therefore, unless be installed in the slot part 139 that powder boxs 130 in the main frame body unit 100 have the identical shape of the powder box that meets with type and are in identical position, otherwise powder box 130 and projecting plate 192 still can be interfered each other, and loam cake 107 can't be closed ideally.Therefore, the operator can recognize that certainly powder box 139 type mismatch of being installed close.
In addition, in this embodiment, on the unitor 152 of the follower 137 of bottle cap 132 and powder box actuator 150, be formed with concavo-convex 137a and 152a, its shape depends on electrophotographic copier type and purposes.
Therefore, during powder box 130 type mismatch in being installed in main frame body unit 100, produce defective and cooperate between the concavo-convex 152a of the concavo-convex 137a of follower 137 and unitor 152, simultaneously, the position of the slot part 139 of powder box 130 moves away the position of the projecting plate 192 of loam cake 107.If the position of slot part 139 moves away the position of projecting plate 192, projecting plate 192 and powder box 130 natures can be interfered each other, and loam cake 107 can't be closed ideally.
Therefore, even powder box 130 has the groove 139 of the powder box same form that meets with type, unless the concavo-convex 137a of follower 137 can be corresponding well with the concavo-convex 152a of unitor 152, otherwise loam cake 107 can't ideal be closed.Therefore, the operator can recognize powder box 130 type mismatch of being installed certainly.
In addition, the groove in the present embodiment 139 is limited by first columnar portion 133, second columnar portion 134 and flange part 136.Therefore, according to the fixed form of second columnar portion 134 and flange part 136, can freely change the width of slot part 139.Therefore, can produce abundant various powder boxs 130 corresponding to a variety of Machine Types and purposes.
And, in this embodiment, between second columnar portion, 134 external peripheral surfaces and flange part 136 inner circumferential surfaces, form the clearance G that has air.Therefore, even when the heat from fixing device is delivered to powder box 130 by partition wall 104, the air in clearance G also can play the effect of cooling piece, stops the ink powder in the developer bottle 131 overheated.Therefore, can not produce the situation of the ink powder fusing in the developer bottle 131 that becomes problem usually.
And even leak the gap of ink powder between developer bottle 131 and bottle cap 132, the ink powder that is leaked can eject from clearance G at once.So, after manufacturing is finished, promptly before the shipment, can find immediately that powder box 130 lost efficacy.Therefore, can reduce unworthy transportation.
In addition, the electrophotographic copier of present embodiment is the simple structure that only obtains by adding identification key 190 on the conditional electronic photorepeater, need be such as being used to detect the electronic installations such as switch whether powder box 130 types meet.Therefore, the structure of electrophotographic copier is also uncomplicated, and, introduce expense required for the present invention and can control very lowly.
As mentioned above, according to electrophotographic copier of the present invention, can prevent the use of the powder box 130 of type mismatch with very low expense.So, compare with conventional art, reduced the generation of printing failure and equipment failure largely.
In addition, in this embodiment, use loam cake 107 and lower cover 108 to close opening 106.Yet the present invention is not limited to this, also can only use a lid.
Second embodiment
Below, describe second embodiment in detail with reference to Fig. 9 and Figure 10.In addition, the structure identical with first embodiment and the explanation of operation will be omitted.Fig. 9 shows the skeleton view according to the inner structure of the front space 103 of second embodiment of the invention, and Figure 10 shows the planimetric map according to the state of the slot part 139 of the projecting plate 192 insertion powder boxs 130 of the identification key 190 of same embodiment.
As shown in Figure 9, the identification key 190 among this embodiment is fixed on the front portion of partition wall 104, rather than is fixed on the inside surface of loam cake 107.The projecting plate 192 of identification key 190 is arranged on the position corresponding with the slot part 139 of powder box 130.
Relation between projecting plate 192 and the slot part 139 will be described below.Suppose that the distance from the front portion of partition wall 104 to the front end of projecting plate 192 is M0, distance between the front portion of partition wall 104 and first columnar portion, 133 external peripheral surfaces is M1, distance between partition wall 104 front portions and second cylinder, 134 external peripheral surfaces is M2, and partition wall 104 is anterior and flange part 136 external peripheral surfaces between distance be M3, the relation between the M0 to M3 is determined as follows:
M1＜M0＜M2 and M3＜M0＜M2.
Therefore, as shown in figure 10, when powder box 130 that type meets was installed in the main frame body unit 100, the projecting plate 192 of identification key 190 did not contact with powder box 130, and enters in the groove 139 of powder box 130.
Yet, if powder box 130 does not have slot part 139, powder box 130 being installed in the process of main frame body unit 100, powder box 130 and projecting plate 192 can be interfered each other, and powder box 130 can't be installed ideally.
Even powder box 130 has slot part 139, unless the position of slot part 139 is corresponding with the position of the projecting plate 192 of identification key 190, otherwise in the process that powder box 130 is installed, powder box 130 and projecting plate 192 can be interfered each other, and powder box 130 equally also can't be installed ideally.
In addition, as an instantiation, the position of slot part 139 is not corresponding with the position of projecting plate 192, for example, the shape of the concavo-convex 137a of bottle cap 132 is not corresponding with the concavo-convex 152a of powder box actuator 150, therefore, the slot part 139 that is installed in the powder box 130 in the main frame body unit 100 moves away the position of projecting plate 192.
In addition, even the position of slot part 139 is corresponding with the position of projecting plate 192, when slot part 139 mistakes are shallow, that is, when the external diameter of second columnar portion 134 is excessive, in the process of the powder box of installing 130, powder box 130 can be interfered each other with projecting plate 192, and powder box 130 can't be installed ideally.
