Chip fixing device and processing box with same for laser printer

Abstract

The invention discloses a chip fixing device and a processing box with the same for a laser printer. The chip fixing device comprises a base and a protection board, wherein the base is provided with a clamping groove and a supporting table; the bottom and the opening of the clamping groove are provided with expanding sections which expand along with the width direction of the expanding sections in the groove cavity extending direction of the clamping groove respectively; at least one shrinkage section which shrinks along with the groove cavity width direction is arranged between two expanding sections; pipe column groups which consist of not less than two pipe columns, are spaced in the preset transverse distance and are longitudinally parallel to each other are fixed on the protection board; the radial dimension of the pipe column is the same as the dimension of the expanding section; the pipe column groups can be transversely inserted into the clamping groove and the pipe column positioned on the outer side of the protection board is inserted first; and when the pipe column group is wholly inserted into the clamping groove, the protection board is attached to the supporting table. The chip fixing device and the processing box with the processing device can effectively improve the assembly efficiency of an integrated circuit chip.

Description

technical field [0001] The invention relates to a chip fixing device and a processing box for a laser printer with the device. The chip contains several integrated circuits that store information about the developer, such as toner. The process cartridge includes a photosensitive drum for forming electrostatic latent images, a waste toner scraper for removing residual toner on the surface of the photosensitive drum, a charging roller for charging the photosensitive drum, and a developing roller for laying toner on the photosensitive drum, etc. Background technique [0002] At present, the processing cartridges used with various laser printers on the market generally have an integrated circuit chip for storing toner information. The chip is used to provide printing information and record the remaining amount of toner reserve. Such chips are generally fixed on the outer surface of the process cartridge at locations corresponding to the connection electrodes of the laser print...
