Description
Technical field
The utility model relates to a kind of Delevoping cartridges for image forming apparatus.
Background technique
Delevoping cartridge in the prior art, which is generally configured, to be detachably mounted in image forming apparatus.Delevoping cartridge has can
To the developer roll of photosensitive drums conveying developer.Photosensitive drums may be provided in independent photosensitive drums box or drawer type photosensitive unit
In group.When Delevoping cartridge is installed into independent photosensitive drums box or drawer type photosensitive unit group, Delevoping cartridge can be with the independent sense
Light drum box or drawer type photosensitive unit group are installed together into image forming apparatus thereby executing print out task.But it is executing
During print out task, it is sometimes necessary to the developer roll of particular color are in discrete state, that is, developer roll with photosensitive drums and do not connect
Touch photosensitive drums.For example, when carrying out black and white printing in color printer, in the Delevoping cartridge of other colors other than black
Developer roll needs separated with photosensitive drums, at this moment, Delevoping cartridge changes relative to the position of bulging box.But it is in the prior art
Delevoping cartridge has chip in the first side wall, which stores the relevant information in relation to Delevoping cartridge, such as the model of Delevoping cartridge, can beat
Printed page number, Delevoping cartridge information such as number of print pages, have in image forming apparatus or drawer type photosensitive unit group and the chip
The electric contact being electrically connected, so that the information stored in Delevoping cartridge chip and real-time monitoring development can be read in image forming apparatus
The state of box.But execute developer roll separated with photosensitive drums during when, due to the Delevoping cartridge with chip relative to
Image forming apparatus moves, so that the chip of Delevoping cartridge also can be mobile relative to the electric contact of image forming apparatus, chip
Friction is just generated between electric contact, the part that usual Delevoping cartridge chip and electric contact are in electrical contact all is by the way that one layer of metal is electroplated
Material is made, and the coat of metal is very thin, if rubbed frequent occurrence with electric contact, is easy to that frictionally damage occurs, thus
So that poor contact between electric contact and chip, causes image forming apparatus that cannot read the information of Delevoping cartridge chip, to scheme
The state of Delevoping cartridge cannot be normally detected as forming device.
Utility model content
The purpose of the utility model is to provide one kind Delevoping cartridges, send out for reducing image forming apparatus and Delevoping cartridge chip

Process.
Image forming apparatus includes the support plate 60 of electric contact 61 and support electric contact 61, and latent for developing electrostatic
The photosensitive drums 70 of picture, electric contact 61 and photosensitive drums 70 are all mounted on the specific position in image forming apparatus.
Fig. 8 is that Delevoping cartridge 1 is just installed along second direction to image forming apparatus, conductive member 22 also not with electric contact 61
Contact, developer roll 13 and photosensitive drums 70 are in discontiguous disengaged position；When Delevoping cartridge in second direction further along installing
When to position shown in Fig. 9, the second guide surface 22d of conductive member 22 is just contacted with electric contact 61, due to the second guide surface 22d
It is configured to inclined surface, so as to be oriented to the installation of the conductive member 22, when Delevoping cartridge 1 continues on second direction installation,
When the electrical contact surface 22b of conductive member 22 is abutted by electric contact 61, electrical contact surface 22b can occur relative to supporter 21
Flexible deformation, and it is mobile to the direction as shown by arrow A close to 21 side of supporter, continue on second party shown in Fig. 10
To by the installation of Delevoping cartridge 1, into image forming apparatus, developer roll 13 is contacted with photosensitive drums 70 at this time, the electrical contact of conductive member 22
Surface 22b is contacted with image forming apparatus contact electric contact 61, is at this time the normal operating conditions of Delevoping cartridge, and electric contact 61 contacts
Electrical contact surface 22b and in a second direction close to the side of the second guide surface 22d；Appoint when image forming apparatus executes printing
When business, when needing to separate one or more in the Delevoping cartridge of multiple colors with photosensitive drums, such as executes black print and appoint
When business, when needing to separate the Delevoping cartridge of other colors with photosensitive drums, a biasing member is provided in image forming apparatus (not
Show) apply a power to Delevoping cartridge so that Delevoping cartridge is moved along third direction shown in Figure 11, so that development
Developer roll 13 in box is separated with the photosensitive drums 70 in image forming apparatus, and in this process, electrical contact surface 22b connects with electricity
Point 61 is always maintained at contact, when completing separating action, the close first guide surface 22c of electric contact 61 and electrical contact surface 22b
Position contact.To which in executing print procedure, even if Delevoping cartridge is separated relative to image forming apparatus, electric contact 61 is still
Keep with the contact of conductive member 22, and in this process, conductive member 22 is contacted with chip 23 always, and conductive member
The 22 one end 22a contacted with chip 23 will not occur to relatively move and rub, so that the contact surface 23a of chip 23 will not occur
Abrasion.When needing to take out Delevoping cartridge from image forming apparatus, it can take out, take out along third direction shown in Figure 12
During, the first guide surface 22c is first contacted with electric contact 61, since the first conducting surface is inclined surface, so as to be oriented to
Delevoping cartridge takes out from image forming apparatus.
The not direct electric contact with image forming apparatus of the chip of the utility model Delevoping cartridge contacts, but in electric contact
It is connect between chip by conductive member, conductive member is contacted with the electric contact of image forming apparatus, aobvious in Delevoping cartridge
During shadow roller is separated with photosensitive drums, conductive member and electric contact are always maintained at electrical contact, and conductive member is thicker, i.e.,
Make to occur to rub that contact of the image forming apparatus with chip will not be influenced；Even if Delevoping cartridge, in separation process, image is formed
The electric contact of device can exert a force to conductive member, since conductive member has elasticity, the electric contact and conduction of image forming apparatus
The friction of component also can very little, the electrical contact surface of conductive member not easy to wear；When Delevoping cartridge takes out from image forming apparatus,
The guiding surface of conductive member can be oriented to the taking-up of Delevoping cartridge.So Delevoping cartridge provided by the utility model can be with picture image
Good electrical contact is kept in device, and can swimmingly be taken out Delevoping cartridge from image forming apparatus.
Above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；Although referring to aforementioned reality
Example is applied the utility model is described in detail, those skilled in the art should understand that: it still can be to preceding
Technical solution documented by each embodiment is stated to modify or equivalent replacement of some of the technical features；And these
It modifies or replaces, the spirit and model of various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
It encloses.
