The invention provides an image forming device and a paper amount detection mechanism and method. The paper amount detection mechanism is used for being matched with a paper storage mechanism on the image forming device, the paper storage mechanism comprises a frame body and a movable lifting plate, the lifting plate is arranged in the frame body, and a grounding terminal is arranged in the frame body and moves along with the movement of the lifting plate. The paper amount detection mechanism comprises a control board, detection circuits and a control unit, wherein the detection circuits and the control unit are arranged on the control board; the detection circuits are used for making contact with the grounding terminal in the moving process of the lifting plate; and the control unit is connected with the detection circuits, is used for acquiring voltage information of the detection circuits, and determines the paper amount information in the paper storage mechanism according to the voltage information of the detection circuits. According to the image forming device and the paper amount detection mechanism and method, the structure is simple, the installation is convenient, the cost is low, reduction of the paper can be accurately judged without using a sensor, a user can be reminded of lack of the paper to supplement the paper, and printing operation can be prevented from being stopped.
Description
technical field [0001] The present invention relates to the technical field of image forming devices, in particular to an image forming device, a paper amount detection mechanism and a method. Background technique [0002] With the continuous development of science and technology, image forming devices are becoming more and more mature; and image forming devices are generally provided with a paper storage mechanism for storing paper and a paper pickup mechanism for extracting paper, in order to keep the paper in contact with the paper pickup mechanism , in some paper storage mechanisms, a lifting plate is set up, and the paper is stacked neatly on the lifting plate. The lifting plate may be lifted by the cooperation of the motor and the gear set. As the paper pickup mechanism continuously extracts paper from the paper storage mechanism, the amount of paper in the paper storage mechanism gradually decreases, and the position of the lifting plate also rises thereupon, so as t...
