A tray drawer and a multi-function printer using the same are provided. The drawer includes a tray body, a handle and an elastic element. The handle is connected to the tray body and includes a handle portion and a first engagement portion. The first engagement portion is connected to the handle portion, wherein when the tray body is at a lock state, the first engagement projects from a first position-limit portion. The elastic element connects the first engagement portion to the tray body. There is no relative motion between the first engagement portion and the handle portion.

A sensing device includes a housing, a supporting component, a grating module, a first roller, a second roller, and a control unit. When a media contacts with the second roller, the second roller drives the first roller to move the supporting component relative to the housing according to a thickness of the media, so as to adjust positions of the first roller and a grating wheel of the grating module relative to the housing. When the media drives the second roller to rotate, the second roller drives the first roller to rotate the grating wheel. The control unit determines whether the media proceeds at a predetermined speed according to a corresponding sensing signal generated by the grating module during rotation of the grating wheel, which allows a user to recognize a progress state of the media.

A sheet-fed scanner comprising a scan channel, a feeding unit, a transmitting unit, a background sheet, a background light source and a scan module is provided. The feeding unit is disposed at an inlet of the scan channel for feeding a document. The transmitting unit transmits the document to pass through the scan channel. The background sheet is disposed on a side of the scan channel, and has a first surface and a second surface. The first surface faces towards the scan channel. The background light source faces towards the second surface to provide an intermittent light signal to the background sheet, so that the background sheet correspondingly displays an intermittent variation background image on the first surface. The scan module is disposed on another side of the scan channel, and captures a document image of a document and the intermittent variation background image to generate scan data accordingly.

A sheet feeder has a transmission mechanism which includes an output gear mesh with a transmission gear train, and a switch element, disposed between the transmission gear train and the output gear, for switching a rotational direction of the output gear. The switch element includes a movable arm, a driving gear driven by the transmission gear train, a switching gear set attached to the arm and meshing with the driving gear, and a clutch device for restricting movement of the arm to enable the switching gear set to be disengaged from the output gear. When the output gear meshes with the switching gear set, the output gear and a transmission shaft of the sheet feeding mechanism may change the direction of their rotation. When the output gear is disengaged from the switching gear set, the output gear and the transmission shaft of the sheet feeding mechanism are not driven by a power source.

A paper pick-up mechanism for a feeder includes a pick-up roller, a pick-up roller shaft, a separation roller, a transmission shaft, a gear set and a transmission gear shaft. Two one-way clutches are respectively coupled to the transmission shaft and the transmission gear shaft in parallel. When the transmission shaft is rotated in a direction opposite to a sheet-feeding direction, the gear set, through the cooperation of the two one-way clutches are used as a planetary gear set to lift up the pick-up roller.
