Imaging box chip, imaging box and identification method for imaging box

Abstract

The invention discloses an imaging box chip, an imaging box and an identification method for the imaging box. The imaging box chip comprises a state acquiring module and a control module, wherein the state acquiring module is used for acquiring the use state information of the imaging box, and the control module is used for generating an optical control signal corresponding to the use state information according to an optical identification rule of an imaging device, so as to control a light-emitting module arranged on the imaging box or the imaging box chip to emit lights towards a light-receiving part arranged on the imaging device. The imaging box chip provided by the invention can be used for controlling the light emission according to the use state information, without the light reflection and transmission of an optical additional part arranged in the imaging box, thereby avoiding the high-precision demand on optical elements and simplifying the structure of a product at the sideof the imaging box. The imaging box chip can imitate the light reflecting the use state information, thereby promoting the reliability of the imaging device for identifying the imaging box.

Description

technical field [0001] Embodiments of the present invention relate to imaging technologies, and in particular to an imaging box chip, an imaging box, and an identification method for an imaging box. Background technique [0002] As is well known, an imaging device is usually used in conjunction with an imaging cartridge, that is, the imaging device consumes toner stored in the imaging cartridge to record an image on an imaging medium. Typical applications such as printers, copiers, etc. When the imaging box is installed in the imaging device, the imaging device will judge and identify the imaging box. On the one hand, it can be determined whether the installed imaging box can match the imaging device through the installation identification information, so as to prevent the imaging device from using an illegal imaging box. On the other hand, during the imaging process, the imaging device will also timely monitor the amount of toner used or remaining in the imaging cartridge,...

AI Technical Summary

Problems solved by technology

[0006] However, there are certain defects in the optical structure of the above-mentioned imaging box to inform the imaging device of the remaining amount of toner: in addition to involving light-emitting components and light-receiving components, this type of method also needs to be provided with additional components on the imaging box, such as prisms, codes, etc. Wheels, reflective materials, optical inks, etc.

The cooperation between the light emitting part, the light receiving part and the additional part often makes its structure too complicated, and various detection and identification errors may occur due to the low precision of the cooperation of each part in practical applications

For example, for OEMs producing such printers, due to the very small size of the optical sensor used in conjunction with the prism, very high precision is required when setting the distance between the light emitting part and the light receiving part, which also increases production accordingly. cost; and in the process of actual use by the user, dust may intrude inside the printer, causing the light receiving part to directly receive the light emitted by the light emitting part without being reflected by the prism, which further leads to errors

For consumable manufacturers that produce compatible ink cartridges for such printers, it takes a lot of manpower and material resources to make this very high-precision prism and the corresponding optical channel. Once the prism and optical channel are not aligned with the optical sensor below, it is easy The consequences of not recognizing the machine and not being able to detect the remaining ink

For the code wheel device, since a torsion spring coupling device is used to drive the gear and the code wheel, the torsion spring will gradually age and lose its elasticity as time goes on, and the time value of the light transmission window on the code wheel is due to It is easily affected by external resistance factors such as toner and has uncertainty. The error generated by the combination of the two will seriously affect the accuracy of the imaging device to identify the imaging cartridge and monitor the remaining amount of toner

In addition, since the light received by the light-receiving part from the light-emitting part must pass through the light-transmitting window on the code wheel, manufacturers of compatible consumables must spend a lot of energy to precisely design the size and shape of the code wheel, which further adds to the Lengthy production steps and unnecessary production costs

In addition, for non-recyclable code wheel devices, it limits the development of compatible general consumables market
