Abstract: A document feeder comprises a hopper table on which documents are to be mounted, a feeding roller for transporting the documents mounted on the hopper table, and lifting system for raising and lowering the hopper table to position the topmost sheet of the documents mounted on the hopper table at a level of the feeding roller. The lifting system includes a hopper motor, and a drive mechanism for raising and lowering the hopper table by means of the driving force. The drive mechanism swings the hopper table when the hopper table is located between an lower limit position and a switching position above the lower limit position, or moves the hopper table vertically with maintaining its posture horizontally when the hopper table is located between the switching position and an upper limit position above the switching position. In addition, the height and the slant angle of the feeding roller sequentially conform to the movement of the hopper table in order to prevent jamming.

Abstract: An image reading and printing apparatus having a housing, a printing part located in the upper part of the housing, an image reading part located in the lower part of the housing, a sheet feeding part located in the lower part of the housing below the image reading part and receiving thereinto a sheet inserted from the lower part of the front face of the housing, a C-like shape sheet conveying path through which the sheet is led from the sheet feed part to the printing part, and is discharged outside of the housing from the upper part of the front surface thereof, and a C-like shape document conveying path through which a document inserted from the lower part of the front face of the housing is led to the image reading part, and is then discharged outside of the housing from the front face of the housing, the C-like document conveying path being surrounded by the C-like sheet conveying path, thereby making it possible to miniaturize the image reading and printing apparatus and to absorb a shift between the ti

Abstract: A scanner printer includes a scanner portion for reading written information on an original manuscript paper and a printer portion for printing written information on printing paper, both of which are integrally combined within a single casing. The respective paper feeding into the scanner portion and the printer portion is performed through a common feeding passage. Thus, the overall dimension of the scanner printer can be downsized. A pointer directs the original manuscript and the printing paper into an original manuscript passage and into the printer portion, respectively. Hence, wear an on a surface of a photo-sensitive drum of the printer portion can be greatly reduced thus maintaining accurate and sharp printing characteristics.
