Abstract: A device providing automatic control of temperature for an environment of a working station includes an air box, a baffle member, and a driving assembly. The air box is coupled to a machine defining a working space which the working station is in. The air box defines an opening. The opening allows cooling air to be introduced into the working space. The baffle member is slidably coupled to the air box at the opening. The driving assembly coupled to the baffle member drives the baffle member to cover the opening completely, to cover the opening partially, or to leave the opening uncovered in accordance with a difference between a current temperature of the working space and a desired target temperature of the working space. A related system and method are also disclosed.

Abstract: A sheet-fed image scanning method and a scanning device thereof are provided. Firstly, a contact image sensor (CIS) scanning element is equipped with at least two sheet-feeding rollers respectively and passively connected with a driven roller, so that the to-be-scanned sheet is fed into/out between the sheet-feeding rollers and the driven rollers. Then, the to-be-scanned sheet is scanned by the CIS scanning element when the to-be-scanned sheet is fed in, and the driven roller is elastically ascended or descended according to the thickness of the to-be-scanned sheet. The invention enables non-contact or low-friction contact scanning between the scan glass window of the scanning device and the to-be-scanned sheet to avoid the to-be-scanned sheet being scratched or damaged and assure the constant-distance scanning to obtain high-quality scanned image. The position of the scanning element can be adjusted to the optimum scanning focal distance according to the thickness of the to-be-scanned sheet.

Abstract: A sheet-fed scanning device with cleaning mechanism is provided. The sheet-fed scanning device includes a housing, a scanning module for scanning a fed-in document, and a cleaning curtain whose one end is fixed on the sheet-fed scanning device. The cleaning curtain is disposed in a sheet-fed direction at the front end of the scanning module, and the edge of the other end of the cleaning curtain is elastically in contact with the fed-in document for cleaning a to-be-scanned surface of the fed-in document. The invention is simple in structure and effective in cleaning the fed-in document. The cleaning mechanism does not cost much, but avoids the scanning quality being affected due to the large friction of the cleaning element. The cleaning mechanism ensures long-term cleanness of the to-be-scanned surface of the fed-in document as well as the cleanness of the glass window of the scanning module and the scanning quality.

Abstract: A cleaning device for scanner includes a handhold portion and a cleaning portion including a window cleaning surface. The handhold portion and the cleaning portion are fixed together, and the thickness of the handhold portion is larger than that of the cleaning portion. The cleaning portion further includes a loading body. The loading body can be a hard or flexible flat board that has a first end, which is fixed with the handhold portion, and a second end. The cleaning process of the cleaning device for the scanner is simple. The window cleaning surface can be replaceable or not and is cheap when manufactured, suitable for being used in any scanner having an immovable scanning module relative to its housing, and more practically, for cleaning the glass window and roller of small size and any portable scanner, so as to maintain scanning quality and scanning precision.

Abstract: A printer of the invention includes a main body, an exit roller and at least one kicking mechanism. The exit roller is rotatably disposed on the main body and comprises a shaft and a rolling portion disposed on the shaft and rotated by the shaft to send paper out of the main body. The kicking mechanism is joined to the shaft and periodically exceeds the exit roller in a paper exit direction to kick the paper from the exit roller.

Abstract: A film holder and a film scan module using the same and a multi-functional peripheral using the same are provided. The film holder is used in a multi-functional peripheral for fixing at least a film. The multi-functional peripheral comprises a cap body and a main body assembled thereon. The film holder comprises a board and a clip portion. The board is movably disposed on the undersurface of the cap body. The clip portion is disposed on the board for fixing the film. The film can be disposed on the board that is fixed on the undersurface of the cap body. When the cap body covers the main body, the cap body is against the board for pressing and making the film spread on the main body.

Abstract: A multi-function printer comprises a printing module, a scanning module, a supporter and a cam. The printing module has an accommodation portion and a supporting groove. The scanning module is rotatably disposed on the printing module. The supporter is rotatably disposed on the scanning module. The cam is rotatably disposed in the accommodation portion and capable of rotating between a first position and a second position. When the scanning module is rotated and opened, the cam rotates and guides the supporter to abut the supporting groove, whereby the scanning module is supported on the printing module. When the scanning module is rotated and closed, the cam rotates and guides the supporter to enter the accommodation portion.

Abstract: A business machine. The business machine comprises a main body having a paper feed slot, an accommodating portion disposed around the paper feed slot and having a guide groove, and a tray loading paper and slidably joined with the guide groove to be positioned in a first position and a second position. When the tray is positioned in the first position, a predetermined angle is formed between the tray and the main body. When the tray is in a second position, the tray is parallel to the guide groove and accommodated in the accommodating portion.

Abstract: A printer. The printer comprises a base having an incline surface for paper on which a depression is formed, a shaft disposed above the incline surface, an arm pivoted on the shaft, a pick-up roller disposed on the tip of the arm, and a free arm with one end pivoted on the arm and the other end free. When the paper on the incline surface runs out, the free arm is rotated and the free end enters and abuts the depression, whereby the arm is supported by the free arm to maintain an appropriate distance to the incline surface.

Abstract: A carrying apparatus for holding an optical scanning module is provided to allow the optical scanning module against the platen. The carrying apparatus at least comprises the first carriage, the second carriage and a carriage control means. The second carriage is pivotably connected to the first carriage. The carriage control means provides an upward force to lift one or both of the first carriage and the second carriage up, thereby allowing the optical scanning module loaded on the carriages against the platen.
