An image reading apparatus according to the present invention comprises an image reading unit arranged on a conveying path of a first medium and reading an image on the first medium, a conveying unit conveying the first medium and a second medium to the image reading unit, a width of the second medium being smaller than the first medium, and guide portions guiding the second medium introduced from a discharge port along the conveying path.

Image reading apparatus and media conveying apparatus

An image reading apparatus including a shading correction mechanism that can be formed by fewer component parts than conventional ones, and is increased in the degree of freedom of design, thereby enabling reduction of the size and weight thereof. A contact glass guides an original to an image reading position. A glass holding member holds the glass. A line image sensor reads an image on the original conveyed to the image reading location, through the contact glass. A reference member is disposed at a location different from the image reading location on the contact glass. A moving mechanism relatively moves the line image sensor and the reference member so that the line image sensor can alternatively read the original conveyed to the image reading location and the reference member. A drive section externally drives the moving mechanism to move the line image sensor and/or the reference member.

A sheet feeding apparatus for separating and feeding sheets supported on a sheet supporting portion one by one is provided with a separating and feeding portion having a sheet feed roller provided downstream of the sheet supporting portion for feeding the sheets, and a separation roller brought into pressure contact with the sheet feed roller, and designed to be rotatable in the same direction as or a direction opposite to the rotational direction of the sheet feed roller, and separating and feeding the sheets one by one, and a transport restriction guide provided near the separation roller so as to protrude toward the sheet feed roller for restricting the number of sheets coming into the pressure contact portion between the sheet feed roller and the separation roller, and the transport restriction guide is formed by a flexible member, and is provided so as to be pressed by the sheets coming into between the sheet feed roller and the separation roller and be flexible toward the separation roller side, and the transport restriction guide is flexed so as to abut against the separation roller.

Sheet feeding apparatus and image forming apparatus and image reading apparatus provided with same

An image reading apparatus includes a transmission type projection screen capable of reading an image projected on an inner surface side of the projection screen from an outer surface side thereof, a projection optical system for projecting an image onto the inner surface side of the projection screen, and a reading unit movable in a projection optical path between the projection screen and the projection optical system for reading image information in an image reading mode. A light shield is capable of being moved to a position where an ambient light incident from the outer surface side of the projection screen, reflected by the projection optical system and entered into the reading unit, is blocked in the image reading mode.

The present invention provides a printing apparatus which can detachably mounted to a main machine and which is driven by a drive source independently from the main machine and is adapted to effect printing of a sheet conveyed from the main machine apparatus body, the printing apparatus having a sheet detect mechanism for detecting presence/absence of the sheet conveyed from the main machine, a sheet convey mechanism disposed at a downstream side of the sheet detect mechanism in a conveying direction within a sheet convey path, a print mechanism for effecting printing on the sheet conveyed by the sheet convey mechanism, and a drive control mechanism for controlling driving of the sheet convey mechanism and the print mechanism on the basis of a sheet detect signal from the sheet detect mechanism.

Printing apparatus

A recording apparatus for recording images of an object on a plurality of recording media records the object images on the recording media at different reduction factors. It also records an object image independently on each of the recording media.

Recording apparatus

A recording system in which film stored in a state of loops can be fed smoothly due to the film guide members which can change their positions depending on the amount of films a sensor means has detected. In addition, the assembly of a film transport unit and a development container can be mounted or dismounted to or from the development unit easily.

Recording system

An image recording apparatus comprises first feed means for feeding a document placed at a supply unit to a record unit;

Image recording apparatus

An image scanning apparatus includes a focusing lens, a mirror for guiding light beams passing through the focusing lens onto a predetermined exposure position of a moving photosensitive drum, a moving unit for causing the mirror to move along a line intersecting a perpendicular bisector of a line segment connecting an imaginary focal plane of the focusing lens and the exposure position, and a rotating unit for changing an angle of the mirror upon movement of the mirror.
