A sheet detection device includes: a magnetic sensing element disposed on a sheet guide, wherein the sheet guide brings the magnetic sensing element to move to a first position or a second position; a first magnetic element disposed on a sheet tray corresponding to the first position; a second magnetic element disposed on the sheet tray corresponding to the second position and in spaced with the first magnetic element; a processing element electrically connected with the magnetic sensing element. When the magnetic sensing element outputs a first voltage signal, the processing element determines the sheet guide is located at the first position according to the first voltage signal. When the magnetic sensing element outputs a second voltage signal, the processing element determines the sheet guide is located at the second position according to the second voltage signal. The first voltage signal is different from the second voltage signal.

Sheet detection device and detection method thereof

A detecting method of a sheet detection device includes: generating, by a first magnetic sensing element, a first voltage signal corresponding to a magnetic element; generating, by a second magnetic sensing element, a second voltage signal corresponding to the magnetic element; determining, by a processing element, a first relative position of the magnetic element relative to the first magnetic sensing element according to the first voltage signal; determining, by the processing element, a second relative position of the magnetic element relative to the second magnetic sensing element according to the second voltage signal; determining, by the processing element, a stopping position of the magnetic element according to the first relative position and the second relative position; determining, by the processing element, a paper size of a paper abutted by a paper guide according to the stopping position. A sheet detection device is also disclosed.

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 automatic detection method for a paper size is disclosed. a plurality of mark points is set on a paperweight along a paperweight direction that is different from a feeding direction. The disclosure senses a plurality of row images combining into a scan image during a paper passing between the paperweight and an image sensor, determines an edge length of the paper based on a range of the mark points covered by the paper, and determines a paper size based on the edge length. The disclosure can effectively detect the paper size without any additional sensors.

Automatic detection method for paper size

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.

The present invention provides a multi-function printer, including a main body, a cover, and a hinge structure. The hinge structure includes a positioning component and a pivoting member. The positioning component is connected to the main body. The pivoting member is connected to the cover and is pivotally connected to the positioning component. The pivoting member is adapted to pivot to a first state so that the cover is closed on the main body and pivot to a second state so that the cover is opened from the main body. The pivoting member includes at least one positioning portion. When the pivoting member pivots to a third state between the first state and the second state, the pivoting member is positioned to the positioning component by the at least one positioning portion.

A document size sensing module adapted to a MFP having a transparent platform where a document is adapted to be placed is provided and includes a moving component movably disposed below the transparent platform along a first axial direction, a first sensor, a second sensor, and a control unit electrically connected to the moving component, the first sensor, and the second sensor. The first and second sensors are disposed on the moving component and arranged along a second axial direction. When the control unit drives the moving component to move along the first axial direction, and at least one of the first sensor and the second sensor senses the document, the control unit determines a length of the document according to a distance travelled by the moving component and a width of the document by the first sensor and the second sensor, so as to determine dimensions of the document.

A scanner cover including a first plate and a second plate is provided. The first plate has a first surface; multiple compressible and deformable elastic structures are arranged protruding on the first surface. The second plate is stacked on the first plate and the second plate has a second surface facing to the first surface, the elastic structures are contacted with the second surface, and deformation of each elastic structure is contained in the second plate while the elastic structures are compressed. While the first plate and the second plate are pressed to move close to each other, the elastic structures are compressed and a restoring force is thereby provided between the first plate and the second plate.

A calibration method of a delta 3D printer, wherein a vertical calibration mechanism is disposed on a vertical direction, a horizontal calibration mechanism is disposed on the horizontal direction and a printing-platform calibration mechanism is disposed under the printing-platform of the 3D printer. Before performing a new printing task, the 3D printer first controls three sliding components to move vertically and performs a calibration on the Z-Axis via the vertical calibration mechanism. Next, controls the nozzle to move horizontally and performs a calibration on X-Axis and the Y-Axis via the horizontal calibration mechanism. After the X-Axis, Y-Axis and Z-Axis are all calibrated, the 3D printer performs a tilt degree calibration on the printing-platform via the printing-platform calibration mechanism. Lastly, after performing all calibration operations, the 3D printer starts to execute the new printing task.
