The technical field

The present invention relates to a cartridge manifestations, used in electronic photographic manifesting the device.

Prior art

The device forming the image type of laser printer, copier, and printer all-in-one electrostatic image is formed on the surface of the photosensitive drum, serving as the carrier of an image, and the electrostatic image on the surface of the photosensitive drum, and then is manifested with the help of the developer held on showing the drum serving as the carrier of the developer on the developer machine to form a visible image. The developed image is transferred to the desired material, and then is fixed on the output material with the help of the fuser unit.

In the prior art, there are such types of image processor, as the photosensitive unit and the processing unit, Rethimno connected to the photosensitive unit. The photosensitive unit includes at least the photosensitive drum and the shaft of the charge transfer. The processing unit includes a developer container, a stirrer, a feed roller, roller manifestations, etc. of the Photosensitive unit and the unit processing unit processing image have similar principles ol the turnout, the internal structure, internal funds and mutual position of these funds. Due to the fact that manufacturers produce different types of devices and to prevent erroneous installation of the cartridge in another printer, various cartridges manifestations supplied restricting the installation of the latches corresponding to a particular type of device, and the actuator is located in a corresponding position on the side wall. Since cartridges manifestations have substantially the same basic design, but must clearly be different in the production, marketing and use, because otherwise they cannot be used, this leads to excessive public costs to some extent.

Disclosure of inventions

The present invention is directed to the creation of the cartridge manifestations that can be used in various devices for forming images.

Hereinafter the present invention will be illustrated in detail with reference to accompanying drawings.

The present invention proposes a cartridge manifestations, which includes a developer container, a stirrer developer, located in the developer container, a feed roller for supplying developer to the roller manifestations, roller manifestation to manifestation electrostatic image on the photoconductor, which is the filing means cartridge manifestations, the receiver power to drive only one gear set gear means for receiving input power. The receiver power is able to rotate in two or more positions to adapt to the position of the actuator devices forming the image.

In the present invention, the initial position of the receiver power is the position of reception of the input power and the device is moving receiver power includes a push block, deflecting block, a spring and a torsional spring. The moving device receiver power operated screw-down block. When the push block device moving receiver power is pressed, the receiver power is rotated to another position receiving input power under the action of torsion springs.

In the present invention, the receiver power and gear 2 are combined with each other, and the gear 2 rotates around the shaft fixed to the side plate 6. Gear 2 and gear 3 is fixed opposite to each other with the plates 6, 7. When the cartridge manifestations installed in the device forming the image, the receiver 1 receives power input power to the drive gear 2 to rotate, the gear 2 is engaged with the gear 3 and the gear 3 is engaged with the gear 4, so that the power of consistently peredav is up to gear 4 for driving the order of rotation of the rotating means of the cartridge manifestations.

In the present invention the pressure block 5 is in contact with the upper part 81 deflecting unit 8 through the wedge surface. When the receiver power 1 is in the initial position shown in the drawing, the right side 82 deflecting unit 8 is located in the recess 10, is made on the side plate 7, so that the gear 2 and the receiver power 1 were recorded at the start position, at this time, the spring 9 is in the stretched condition.

In the present invention when it is required to place the receiver power 1 second actuator position, the push block 5 is pressed in the direction as shown by arrows so that the push block 5 hit on the upper part 81 deflecting unit 8 through klinovuyu surface to compress the spring 9, and at the same time deflecting unit 8 is moved and shifted in the direction of the arrow in the drawing so that the right portion 82 extends from the notch 10. The torsion spring 11 is located on the side plate 6, one end is placed in the hole of the side plate 6, and its other end rests on the inner bottom portion of the deflecting plate 12. When the right part 82 deflecting unit 8 extends from the notch 10, the force of elasticity of the torsion spring 11 acts on the side plate 6 so that the receiver power 1 is rotated in the second actuator position, thereby completing the operation.

In the present the present invention the upper surface of the cartridge manifestations is a flat surface.

The present invention provides a movable actuator position through the use of the above technical solutions. When the product image formation type laser printer produced by the plant, actuator position is a fixed position by the set of gears, while the position of the actuator can be automatically changed by the rotation to another position due to the simple operation of the user, thereby the cartridge can be adapted to two or more types of devices with two or more different positions of the actuator. In other words, the cartridge manifestations is versatile for use in various devices, which significantly reduces public costs. For manufacturers of consumables reduces the number of required molds and production lines for the production of different cartridges manifestations, and for sellers and buyers eliminated some unnecessary problems that occurred because of too many varieties of cartridges manifestations.
