The movable scanning module is movable between a first position and a second position. The automatic document feeder has a flip path, a feeding path, an output path, a returnable path and a feeding wheel group. The feeding path is disposed corresponding to the first position and connecting with the feeding tray and the flip path. The output path is disposed corresponding to the second position and connecting with the first output tray. The returnable path has an intersection connecting with the flip path and the output path. The movable scanning module scans two sides of the sheet at the first position and the second position respectively.

An automatic document feeding device having a main body, a stopping assembly, an actuating assembly and a controller. The main body has a sheet conveying channel of a curvature shape. A sheet feeding roller assembly and a sheet conveying roller assembly are arranged on the sheet conveying channel. The stopping assembly is arranged between the sheet feeding roller assembly and the sheet conveying roller assembly. The stopping assembly is capable of being located in or out of the sheet conveying channel. A buffering channel is located between the stopping assembly and the sheet feeding roller assembly. The controller is electrically connected with the actuating assembly and the sheet feeding roller assembly. The controller controls the actuating assembly to hold the stopping assembly in the sheet conveying channel to block the sheet conveying channel in a predetermined period, and then controls the actuating assembly to stop holding the stopping assembly.

Automatic document feeding device

This disclosure is directed to an automatic sheet feeding device having a flipping mechanism which is used for a sheet. The automatic sheet feeding device has a sheet outputting tray, a sheet outputting channel, the flipping mechanism and a switching guide mechanism. The sheet outputting channel is disposed corresponding to the sheet outputting tray. The flipping mechanism is arranged between the sheet outputting channel and the sheet outputting tray. The switching guide mechanism is arranged between the sheet outputting channel and the flipping mechanism, and the switching guide mechanism is used for guiding the sheet to be conveyed to the sheet outputting tray from the sheet outputting channel or conveyed to the sheet outputting tray from the flipping mechanism. Therefore, an efficiency of duplex scanning of the automatic sheet feeding device may be improved.

A dual-axle linkage detection structure includes a first object, a second object, a sensor body, and a shielding element. The first object is movably connected to a base. The second object is movably connected to the first object. The sensor body is disposed on the first object and includes detecting positions. The shielding element includes a shielding part. When the second object covers the first object and the first object covers the base, the shielding part moves into the detecting position. When the second object moves away from the first object, or when the first object moves away from the base and drives the shielding element to rotate, the shielding part moves out of the detecting position.

An ink circulation system, including an ink cartridge, an ink tank, an ink pump, first, second, and third valves, a print head, a heating assembly, and a positive-negative pressure assembly, is provided. The ink cartridge has an output pipeline and an ink cartridge valve. The ink tank is disposed on one side of the ink cartridge and connected to the output pipeline. The ink pump is connected to the output pipeline and the ink tank through an ink pipeline. The first valve is connected to the ink tank through a first pipeline. The second valve is disposed on the output pipeline. The third valve is connected to the output pipeline and the ink pipeline through a return pipeline. The print head is connected to the ink tank and the return pipeline. The heating assembly is disposed in the ink tank. The positive-negative pressure assembly is connected to the first pipeline.

This disclosure is related to a duplex scanning device. The automatic document feeder includes a paper feeder body, a paper inlet and a paper outlet. The paper cassette includes an upper paper tray and a lower paper tray adjacent to the paper inlet and the paper outlet. The cassette power module includes a motor set and a transmission part. The transmission part drives the paper cassette to move on one side of the automatic document feeder to control the lower paper tray to connect with the paper inlet or the paper outlet. Therefore, the double-sided scanning of the document is completed by two-pass duplex scanning.

Duplex scanning device

A paper-feeding device and a multi-function printer (MFP) using the paper-feeding device are provided. The MFP includes a housing with the paper-feeding device installed thereon. The paper-feeding device includes an outer case, an inner case and a retainer. The outer case has first side-walls, openings and slots, in which each opening and each slot on the opening are correspondingly disposed on each first side-wall. The inner case is located beside the first side-walls of the outer case and has a second side-wall. The second side-wall has a position-limiting rib protruding towards the first side-walls. The retainer is located between the first side-walls and has a body, a protrusion and a pivot, in which the protrusion is disposed at a top-portion of the body and correspondingly located in the slots, and the pivot is located between the protrusion and a retaining-portion of the body and correspondingly locked in the openings.

Paper-feeding device and multi-function printer

A paper feeding device and a multi-function printer using the same are provided. The paper feeding device includes a frame, a top cover, a set of gear chains, a power unit and a set of driving gears. The set of gear chains and the power unit are disposed on a side of the frame. The set of driving gears is disposed on the top cover. When the top cover is closed relatively to the frame, the set of driving gears interferes with the power unit, and the power unit provides a power to enable the set of driving gears to rotate, so as to drive the set of gear chains. When the top cover is opened relatively to the frame, the set of driving gears releases interference with the power unit and the set of gear chains, and the set of gear chains is at a free rotation status.

A blocking module is used for blocking at least an object from passing through a rail. The blocking module includes a linkage member and a blocking member. The linkage member has a first end and a second end, and there is a buffering space at a side of the first end. The blocking member has a pivoting end and a free end, in which the pivoting end is pivoted at the second end and the free end hangs down under the pivoting end due to gravity. When the free end of the blocking member leans against on the object on the rail, the object applies a counterforce onto the blocking member so as to drive the first end of the linkage member to move towards the buffering space. The invention also discloses a multi-function printer.

A stopping device and a multi-function peripheral (MFP) using the same are provided. The stopping device disposed in a track having a recess includes a driving unit, a forcing unit, a first restricting point, a second restricting point, a rotating unit, and a stopping unit. The forcing unit has a pivoting portion pivoted with the driving unit and a forcing portion. The forcing portion is located between the first restricting point and the second restricting point aligned in a perpendicular direction. The rotating unit has a rotating axle, and a first end and a second end located at two opposite sides of the rotating axle. The forcing portion of the forcing unit contacts the first end. The stopping unit has a third end and a fourth end. The third end has an opening, through which the second end of the rotating unit passes.
