Abstract: To provide a reading/printing apparatus and a reading apparatus by which the facility with which each unit is assembled and maintained can be significantly improved because steps of fixing and connecting individual units need not be performed in order, a printing apparatus, a control board, and a power supply are disposed inside a housing obtained by integrally forming a base portion serving as a bottom surface, side walls serving as outer side surfaces, and an opening surrounded by the side walls. The reading apparatus, the printing apparatus, the control board, and the power supply are discretely constituted. The housing includes a first housing integrally formed with enough strength to separately fix the base portion, lower portions of the side walls, the reading apparatus, the printing apparatus, the control board, and the power supply, and a second housing covering the opening and integrally forming upper portions of the side walls.

Abstract: Present invention relates to a sheet feeding apparatus comprising, feeding means for feeding sheets; and limiting means movable to a limiting position for limiting a front end of the sheets and to an escape position for releasing the limitation. And the sheet feeding apparatus releases the limitation on the front end by the limiting means before the sheets start to be fed.

Abstract: The present invention provides a sheet separating and conveying apparatus for separating stacked sheets and for conveying a separated sheet, comprises a sheet convey means for conveying the sheet, a friction means disposed in a confronting relation to the sheet convey means, a biasing means for urging the sheet convey means and the friction means against each other, a preliminary convey means adapted to be urged against the sheet convey means at an upstream side of a contact position between the sheet convey means and the friction means in a sheet conveying direction, and a friction releasing means for separating the sheet convey means and the friction means from each other, and wherein, when the sheet convey means and the friction means are separated from each other by the friction releasing means, the preliminary convey means is maintained in a condition that the preliminary convey means is urged against the sheet convey means.

Abstract: A reading recording apparatus such as a facsimile apparatus is provided with a reading portion which causes an original conveying path to convey an original and reading image information, and a recording portion which causes a recording sheet conveying path to convey a recording sheet and effecting recording thereon, wherin an operating portion is disposed on the upper surface of an apparatus body, a lid member is provided openably and closably relative to the apparatus body, with the lid member, when in its closed position, covering the operating portion, and when in its opened position, supporting the original and the recording sheet so as to be guided by the original conveying path and the recording sheet conveying path, whereby the reading-recording apparatus has a well-balanced and compact structure.

Abstract: A wheel for maintaining a constant distance between an ink discharge plane of a recording head and a recording sheet is provided on a carriage such that it is upstream of the recording head as viewed in the direction of movement of the recording head in a unidirectional print mode. A sensor monitors whether the recording sheet is moved off a contact of a feed roller which feeds the recording sheet to a record position and a pinch roller. Before a trailing edge of the recording sheet is moved off the contact of the feed roller and the pinch roller, bilateral recording is conducted to print in each of forward movement and backward movement of the carriage. When the sensor detects that the trailing edge of the recording sheet has been moved off the contact of the feed roller and the pinch roller, the recording is switched to unilateral printing. The print range at the trailing edge of the recording medium is thus extended.

Abstract: A facsimile apparatus comprises a facsimile unit for sending data corresponding to image data that has been received, and a printer unit for performing image recording by discharging ink droplets in accordance with data sent from the facsimile unit. A first CPU for the control of the facsimile unit sends, after one page of image data, data in a predetermined pattern and further a paper exhausting command to the printer. A second CPU of the printer unit performs a paper exhausting operation upon receiving the paper exhausting command, after recording of the predetermined pattern, and upon conveying the recording paper up to a predetermined position, sends a signal for starting detection of the predetermined pattern to the first CPU. The first CPU thereby receives a detection signal from a photo sensor. The second CPU further conveys the recording paper, and at a timing of exhausting out of the apparatus, sends a signal for the detection end of the predetermined pattern to the first CPU.

Abstract: An information processing apparatus includes a program memory (4, 40) and circuitry for switching mapping schemes so as to deal with both direct and bank mapping schemes without alteration of programs. The program memory (4) includes a first memory area (14, 15) formed of a plurality of memory blocks for storing a first program (100) for the bank mapping and a second memory area (16, 17) utilized as a memory block for storing a second program for direct mapping. In the bank mapping, each memory block is mapped into a same address area of an address space of the processor. In the direct mapping, the first and second memory areas are mapped in one-to-one correspondence into the address space. Alternative program memory (40) includes a first memory block (50) storing a first program and a second memory block (60) storing a second program. A predetermined identification information ("JA") is stored in a predetermined memory location of the second memory block.
