Abstract: A sheet-fed scanning device including a first scanning channel and a second scanning channel disposed in parallel, a first sensing element and a second sensing element is provided. The first sensing element corresponds to the first scanning channel for acquiring the image of a first type object. The first type object has a first surface which is adjacent to the first sensing element and within the range of the field depth of the first sensing element. The second sensing element corresponds to the second scanning channel for acquiring the image of a second type object. The second type object has a second surface adjacent to the second sensing element and a third surface dented to the second surface, wherein the third surface is within the range of the field depth of the second sensing element.

Abstract: A scanning method of scanning apparatus and a scanning apparatus are provided. Firstly, when the scanning apparatus is in the default reflective document scanning state and a document is placed in the scanning apparatus, the scanning apparatus automatically activates reflective document scanning function to perform scanning. Next, a document holder is disposed in the feeding entrance of the scanning apparatus, wherein after the scanning apparatus activates the transmissive document scanning state and the document is placed in the document holder, the scanning apparatus automatically activates transmissive document scanning function to perform scanning. The scanning method automatically activates corresponding scanning function without performing document recognition, incurs lower power consumption, produces fast recognition, and is applicable to various scanning apparatuses having both reflective document and transmissive document scanning function.

Abstract: A film holder is provided. During scanning of a to-be-scanned object, the film holder is inserted into a scanning device. The film holder includes an input portion, a guiding portion and a leveling portion. The input portion has an entrance, a channel and an exit, the channel disposed between the entrance and the exit. During scanning of the to-be-scanned object, the to-be-scanned object passes through the channel. The guiding portion connects to the input portion for guiding the to-be-scanned object. The leveling portion is disposed on one side of the channel. During scanning of the to-be-scanned object, the leveling portion leans against the to-be-scanned object. The sensing unit stably senses the to-be-scanned object. The to-be-scanned object inside the film holder is kept from being scratched and the to-be-scanned object is in smooth move during scanning.

Abstract: A film holder is provided. During scanning of a to-be-scanned object, the film holder is inserted into a scanning device. The film holder includes an input portion, a guiding portion and an information window. The input portion has an entrance, a channel and an exit, the channel disposed between the entrance and the exit. During scanning of the to-be-scanned object, the to-be-scanned object passes through the channel. The guiding portion connects to the input portion for guiding the to-be-scanned object. The information window is formed at and through the guiding portion. During scanning of the to-be-scanned object, the side regions of the to-be-scanned object pass through the information window. Functions of the scanning device are effectively augmented; the film is kept from being scratched; the quality of image scanning is kept from being deteriorated; and it is convenient to use the scanning device.

Abstract: A paper-blocking mechanism is disposed in a printer. The printer includes at least a main body and an exit roller. The paper-blocking mechanism includes a stopper portion and a stopper elastic element. The stopper elastic element is fixed on the printer and is compressibly connected with the stopper portion. When the tail of the paper leaves the stopper portion, the stopper elastic element drives the stopper portion to rise to be higher than the surface of the exit roller to block the paper exit lest the paper might be back-rolled and jammed.

Abstract: A printer with print head cleaning function is provided. The printer includes a housing, a round shaft, a carrier and a clean housing. The round shaft is disposed in the housing. The carrier is reciprocally disposed on the round shaft. The carrier is used for carrying one cartridge of the printer. The clean housing is equipped with a cleaner, which is used for cleaning one print head of the cartridge. When the carrier moves upward or downward, the carrier mechanically drives the clean housing to move upward or downward to maintain a fixed interference distance between the cleaner and the print head for enabling the cleaner to clean the print head and maintain the printing quality.

Abstract: A multi-function printer and a supporting mechanism thereof. The multi-function printer comprises a printing module, a scanning module rotatably disposed on the printing module and a supporting mechanism. The supporting mechanism comprises a supporter rotatably disposed on the scanning module, and a constraining mechanism disposed in the printing module. When the scanning module is lifted from the printing module, the supporter is constrained by the constraining mechanism to position the scanning module at a predetermined angle with respect to the printing module. When the scanning module is further lifted to a limit position, the supporter is released from the constraining mechanism, whereby the scanning module descends to the printing module and the supporter is accommodated in the printing module.

Abstract: A sheet feeding apparatus includes an input tray, a paper picking device, and a paper separation device. The input tray is for placing a plurality of papers. The paper picking device is for performing a paper picking operation on the papers. The paper separation device, including a paper separation surface contacting with the papers placed on the paper tray, is for applying a paper separation force on each of the papers as fed in. When the paper picking device performs the paper picking operation on each of the papers, the paper separation forces applied on the papers are decreased as their paper separation paths are increased.
