Description

Cartridge

Technical field

The utility model relates to a kind of cartridge, refers to a kind of cartridge that is fixed with chip especially.

Background technology

Electrophotographic image generates equipment by increasingly extensive use, wherein laser printer is again that a kind of common electrophotographic image generates equipment, its employed cartridge is removable to be installed on the laser printer, cartridge inside comprises a powder storehouse that holds carbon dust, is used for providing carbon dust to laser printer.

Generally be fixed with a chip that possesses the storage memory function on the existing dismountable cartridge, be used to write down the cartridge data such as information, carbon dust behaviour in service of dispatching from the factory.For example the accompanying drawing 4 in the CN1459673A Chinese invention patent ublic specification of application has disclosed a kind of comparatively typical cartridge structure, and its chips is fixed on the cartridge.When cartridge was inserted in the printer, the chip on the cartridge was electrically connected with the electric contact of printer, carried out the transmission of signal thus between printer and cartridge.Also disclose a kind of chip structure in the instructions of above-mentioned patented claim, it comprises substrate, integrated circuit (IC), electrical pickoff, and wherein electrical pickoff and integrated circuit (IC) are to be on the one side of substrate, and conduct each other.In actual manufacture process, usually electrical pickoff is actually one deck Copper Foil that adheres on the circuit board, in use, electric contact on the printer slides on Copper Foil, removing may be attached to the dust that Copper Foil electrically contacts that influences on the Copper Foil, and the electric contact on the printer is normally made with metal spring materials such as phosphor bronzes.

Said chip in use is to paste on the relevant position of cartridge by Double-face gummed paper, its stickup face must be very smooth, electrical pickoff and integrated circuit then are on the non-stickup face, in the use of cartridge, need to keep certain pressure to be applied on the electrical pickoff of chip substrate, to keep stable electrical connection.

Yet there are two apparent in view defectives in the chip fixed sturcture of above-mentioned cartridge:

The first, the mode of using Double-face gummed paper to paste can not guarantee highly stable connection, in use may produce the situation that chip is loosening even come off, and makes the serviceability instability of cartridge;

Second, the chip that more renews if desired, then needing to apply bigger external force extracts original chip by force from cartridge, after original chip picked-off, Double-face gummed paper is most probably attached on the cartridge, be difficult to remove, it is fixing to make that new chip is not easy to be flattened, and also can have influence on the serviceability of cartridge.

And part cartridge on the market must be taken cartridge earlier apart when needs are changed chip, and is so just inconvenient more, even may cause damage to cartridge.

Therefore, provide a kind of cartridge of chip and stable work in work that can be convenient for changing in fact for necessary.

Summary of the invention

The purpose of this utility model is a kind of cartridge that can be convenient for changing chip and stable work in work of design.

For achieving the above object, the cartridge that the utility model provides comprises: hold carbon dust the cartridge main body, be arranged on chip holding part, the rotary chip baffle plate on the cartridge main body and be arranged at chip in the described chip holding part, described rotary chip baffle plate comprises main body, be arranged on the turning axle of main body one end and be arranged on a plurality of grooves on the main body, and described rotary chip baffle plate is by the rotatable chip holding part top that is arranged on of turning axle.

Cartridge described in the utility model adopts the ccontaining chip of chip holding part, and rotary chip baffle plate be can be rotatably set in chip holding part top by turning axle, make chip install easily, change, and chip is also very firm with being electrically connected of printer, therefore, the serviceability of cartridge is also very reliable.

Fig. 2 is the stereographic map of the rotary chip baffle plate of cartridge described in the utility model;

Fig. 3 is the stereographic map of the chip baffle plate of cartridge described in the utility model when opening;

Stereographic map when Fig. 4 is the chip flapper closure of cartridge described in the utility model;

Below in conjunction with the diagram and embodiment the utility model is described in further detail.

Embodiment

In conjunction with referring to Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, cartridge A described in the utility model comprises cartridge main body 1, be arranged on chip holding part 10 on the cartridge main body 1, be rotatably provided in the rotary chip baffle plate 11 and the chip 2 of holding part 10 tops.

Comprise the elements such as powder storehouse that hold carbon dust in the cartridge main body 1,, do not do at this and give unnecessary details owing to have nothing to do with goal of the invention of the present utility model.Be provided with a chip holding part 10 that is used to hold chip 2 on the sidewall of cartridge main body 1, a chip draw-in groove 12 is set in the chip holding part 10, chip 2 is inserted in the chip draw-in groove 12 and is fixed securely.Correspondence is provided with a plurality of electric contacts (figure does not show) on the chip 2, is used for the data transmission of chip 2 is given printer or received corresponding data from printer.

Printer is depended in the position of chip holding part 10, and purpose is after cartridge A is inserted in the printer, and chip 2 can be on the correct position and with printer sets up corresponding electrical connection, and then can finish the exchange of data.

Emphasis is with reference to shown in Fig. 2, rotary chip baffle plate 11 comprises main body 110, be arranged on the turning axle 111 of main body 110 1 ends, be arranged on the projection 112 of main body 110 other ends and be arranged on a plurality of grooves 113 on the main body 110, in the present embodiment, the turning axle 111 of rotary chip baffle plate 11 is rotatable to be fixed in the receiving slit (figure is mark) of two relative vertical side of chip holding part 10, and thus with 1 rotatable connection of cartridge main body, this fixed form is disclosed among Fig. 1 and Fig. 3 very clearly.

The replacing chip processes of cartridge A described in the utility model is as follows, operating rotary chip baffle plate 11 at first, make it rotate to the open mode shown in Fig. 3 around turning axle 111, take out the chip (figure does not show) that need be replaced then, and the chip 2 that will need to change is inserted in the chip draw-in groove 12, operating rotary chip baffle plate 11 then, make it rotate to the closed condition shown in Fig. 4 around turning axle 111, simultaneously, in protruding 112 the corresponding mounting hole (figure does not show) that snap on the cartridge main body 1,, make closed condition more stable by protruding 112 fixing rotary chip baffle plates 11, simultaneously, the described chip holding part 10 of rotary chip baffle plate 11 sealings.After installing, a plurality of contacts on the chip 2 are respectively over against a plurality of grooves 113, like this, when cartridge A correctly was installed in the printer, the respective electrical contact point of printer was just in time passed a plurality of grooves 113 and is set up firm electrical connection with a plurality of contacts of chip 2.

Obviously, by foregoing description as can be known, cartridge A described in the utility model adopts chip holding part 10 ccontaining chips 2, and rotary chip baffle plate 11 be can be rotatably set in chip holding part 10 tops by turning axle 111, make chip 2 install easily, change, and chip 2 is also very firm with being electrically connected of printer, and therefore, the serviceability of cartridge A is also very reliable.

Certainly, the utility model is not limited to above-mentioned embodiment, for example, rotary chip baffle plate 11 is not limited only to shown in the foregoing description, according to circumstances, can also change projection 112 shape and number etc., as long as make rotary chip baffle plate 11 to fix more securely.Suchlike minor alteration and equivalent transformation all should be included within the described scope of claim.
