Paper support

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 light sensing apparatus includes a sheet passage, a first sensing assembly and a first background sheet. The sheet passage has a scan window. The first sensing assembly disposed on a first side of the scan window outputs first scan light to the scan window. The first background sheet disposed on a second side of the scan window has a first reflective surface reflecting the first scan light, passing through the scan window, back to the first sensing assembly through the scan window. The first reflective surface of the first background sheet and the scan window are disposed in a non-parallel manner. Therefore, a light sensing method is also provided to achieve the effects of brightness calibration and boundary detection of the first sensing assembly.

A two-sided scanning device includes a first image scanning module, a second image scanning module, a first scanning background component, a first brightness calibration component, a second scanning background component, and a second brightness calibration component. When the second image scanning module moves relative to the first image scanning module to a scanning position, the second image scanning module drives the first scanning background component to move relative to the first image scanning module, so that the first image scanning module and the second image scanning module are aligned with the first scanning background component and the second scanning background component, respectively. Therefore, the first scanning background component and the second scanning background component can be scanning backgrounds for the first image scanning module and the second image scanning module to generate a scanning image of an object with a size corresponding to an actual size of the object.

The present disclosure provides a transmission assembly and an office machine comprising the same. The transmission assembly includes a body, a first roller, a second roller, a flexible element, a third roller and a transmission element. The first roller is pivoted at a first position of the body, the second roller is pivoted at a second position of the body, one end of the flexible element connects to the body, the third roller is pivoted besides the first roller in parallel and rotates with the first roller simultaneously, and a transmission element is used to surround axes of the first roller and the second roller; wherein, the rotating directions of the first roller, the second roller, the third roller and the transmission element are the same. The present disclosure provides another office machine using the same.

The disclosure provides a scanning device including a flatbed scanner and an ADF. The flatbed scanner includes a first body, a transparent substrate disposed on top surface of the first body, a first film disposed on top surface of the transparent substrate, and an image capturing module disposed under bottom surface of the transparent substrate. The ADF includes a second body, a backplane disposed at bottom of the second body for covering top surface of the flatbed scanner, a paper passage disposed inside the ADF, and a second film. An open portion is configured in the paper passage corresponding to top surface of the transparent substrate, and results communication between the paper passage and top surface of the transparent substrate. The second film is disposed at paper entrance of the open portion. Wherein, the first film and the second film are not overlap on top surface of the transparent substrate.

A sheet separation mechanism comprises a separation roller set and a reverse roller set rotating in the same rotation direction. The reverse roller set presses sheets onto the separation roller set to stop one or multiple ones of the sheets close to the reverse roller set from passing through a nip between the separation and reverse roller sets, and allow the sheet directly contacting the separation roller set to pass through the nip. The reverse roller set comprises a shaft, and two reverse rollers and an annular member all mounted on the shaft, which rotates the reverse rollers. The annular member, disposed between the two reverse rollers, is rotatable relatively to the shaft and movable relatively to the shaft in a radial direction of the shaft. The annular member and the reverse rollers commonly press the sheets. A sheet-fed scanning apparatus using the sheet separation mechanism is also provided.

Tray drawer

The present invention discloses a stacking tray device to be used for a business machine. The stacking tray device comprises a tray, a guide plate and a stopper, wherein paper is placed on the tray, the guide plate moves relative to the tray and restricts the size of the paper, and the stopper sets the position where the guide plate stops when the guide plate is pushed from the center towards the outside. When the stopper is in a lock position, the guide plate stops at a first position corresponding to a first standard paper size; when the stopper is in an unlock position, the guide plate stops at a second position corresponding to an oversized paper size.

Stacking tray device

A multi-mode scanner comprises a first body, a second body and a scanning module. The first body connected to the second body has connected first and second sides. A passageway accommodating a first portion of a bent document is formed between the first and second bodies. A second portion of the bent document is connected to the first portion of the bent document and supported by a second side of the first body. The first and second bodies are configured such that a weight of the bent document makes the second portion be in flat surface contact with the second side, or makes the first portion be in flat surface contact with first side. The scanning module disposed in one or both of the first and second bodies performs an image scan operation on the first portion of the bent document in the passageway to obtain an image signal.

Multi-mode scanner

A multi-purpose scanner comprises a first body, a second body and a scanning module. The second body is disposed on the first body. A first passageway and a second passageway, which are for accommodating a first portion and a second portion of an angled document, and are disposed on a first plane and a second plane, respectively, are formed between the first body and the second body. An included angle is formed between the first plane and the second plane. The scanning module, disposed in the first body and/or the second body, performs an image scan operation on the first portion of the angled document in the first passageway to obtain an image signal.
