Abstract: The present invention relates to a cleaning device for cleaning a mopping cloth of a self-propelled cleaning apparatus. The cleaning device includes a clean-water tank, a waste-water tank, a base, a cleaning unit, a clean-water pipeline and a waste-water pipeline. The cleaning unit includes a water outlet, a cleaning brush and a cleaning chamber. The water outlet is configured to spray a cleaning liquid toward a direction away from the base. The cleaning brush cleans a mopping cloth. The clean-water pipeline communicates between the clean-water tank and the water outlet and is for the cleaning liquid in the clean-water tank to pass through the clean-water pipeline and be sprayed from the water outlet. The waste-water pipeline communicates between the waste-water tank and the cleaning chamber of the cleaning unit and is for the cleaning liquid sprayed while the cleaning unit cleans the mopping cloth to pass through the waste-water pipeline and be collected in the waste-water tank.

Abstract: The present invention involves a washing device and a cleaning method for cleaning self-moving cleaning devices. The cleaning method includes: moving the self-moving cleaning device towards the washing device, and causing a first side of the self-moving cleaning device to be aligned with the washing device, wherein the self-moving cleaning device includes a mop; and moving a mop to a location over a cleaning unit of the washing device, and cleaning the mop of the cleaning member of the cleaning unit, including, during a first period, causing the cleaning unit in a first direction over the first side; and during a second period, causing the self-moving cleaning device to move in a second direction different from the first direction.

Abstract: The present invention provides a wafer notch leveling device, which comprises a body, a first rotating portion, a positioning portion, a power portion, and a control unit. The body has a support portion and a pivot portion is provided at each terminal of the body, the pivot portion pivotally connects a plurality of supporting arms. The first rotating portion and the positioning portion are electrically connected with the power portion. The power portion is electrically connected with the control unit. Especially, when a plurality of wafers are placed on the support portion and fixed, the first rotating portion is electrically connected with the power portion through the control unit to drive the plurality of wafers to rotate the wafers, a notch on the wafer is leveled through the positioning portion.

Abstract: A sheet feeding mechanism having a pickup roller, a switch device, and a gear set is disclosed. The pickup roller drives a recording material to a first path, and the recording material proceeds from the first path to a second path or from a third path to a fourth path when the switch device is switched to a first position, and proceeds from the first path to the third path when the switch device is switched to a second position. The gear set drives the recording material from the first path to the third path when the switch device is switched to the second position and drives the recording material from the first path to the second path, from the third path to the fourth path, and from the fourth path to the first path when the switch device is switched to the first position.

Abstract: A toner fuser includes a pressure roller for pressing toners on a print medium so as to fuse the toners on a print medium, and a rolling heating component for clamping the print medium with the pressure roller and heating the pressure roller. A fusing region is formed between the pressure roller and the rolling heating component. The toner fuser further includes a rolling preheating component installed on a side of the pressure roller for preheating the pressure roller and a part of the print medium not entering into the fusing region.

Abstract: The present invention is directed to a shutter system for electrophotographic machines that effectively reduces the impact of ambient light-on the photoreceptor, or image-bearing member. The shutter system of the present invention utilizes a shutter member that substantially covers the cartridge chamber when in a closed position. Preferably, the shutter member is disposed at the opening of the cartridge chamber. The shutter member is held in place by one or more support brackets.
