Abstract: An image reading apparatus capable of preventing the occurrence of a streak and reading a quality image from the leading edge to the trailing edge of a original. An original is conveyed along a convey pass. The original being conveyed is guided by a guide member, at least part of the guide member being transparent. An image of the original being conveyed is read by an image sensor through the guide member. Airflow is generated, the airflow being blown into the convey pass from a location upstream in a conveying direction compared to a location of the image sensor. The guide member has a convex portion disposed at a location upstream in the conveying direction compared to the location of the image sensor.

Abstract: 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.

Abstract: A sheet feeding apparatus has a pair of feeding roller and separating roller an inter-shaft distance changing mechanism for the pair of rollers, and sheet detecting means, and a sheet fed is rammed against the surface on which the feeding roller and the separating roller overlap each other to thereby correct skew feeding, and the feeding roller and the separating roller are moved away from each other to thereby feed the sheet. When the passage of the fed sheet between the feeding roller and the separating roller is detected the feeding roller and the separating roller assume a state in which sheet feeding is impossible. By the above-described operation being performed for each sheet, the correction of skew feeding and the separation of a sheet are effected by the feeding roller and the separating roller.

Abstract: An image reading apparatus is capable of being switched between an observation state in which an image on a recording medium is projected onto a screen and observed and a read state in which the image is projected onto a reading unit and read. The apparatus includes a projecting lens provided in a lower portion of the apparatus to project the image, a rockable first reflecting member provided in an upper portion of the apparatus to reflect the image light from the projecting lens and, a second reflecting member provided in opposition to the screen to guide the image light reflected by the first reflecting member to the screen. A third reflecting member is provided below the second reflecting member to guide the image light reflected by the first reflecting member to the reading unit. The observation state and the read state are switched by the rocking motion of the first reflecting member.

Abstract: An image forming apparatus includes an image illuminating section having an illuminating lamp for projecting an image and a heater-type fixing device. In the image forming apparatus, the image illuminating section and the heater-type fixing device are adjacent to each other, and the fixing device is heated by the heat of the illuminating section. This prevents a waste of energy, shortens the rise time of the fixing device and the operating time of a heater for heating a heating roller of the fixing device, and obtains good fixing properties even in a low-temperature environment.

Abstract: In an image projecting apparatus such as a microfilm reader and a microfilm reader printer, the inclination angle of a screen surface can be changed without causing distortion and blur in a projected image on the screen surface. The inclination angle of the screen can be changed for the user to see the screen surface with ease such that the screen surface becomes perpendicular to the user's line of sight and the external light reflected by the screen surface is prevented from entering the user's eyes.

Abstract: An image recording apparatus provided with a reader for reading information for identifying an original document; a recording unit for recording the image of the original document on a recording medium; a selector for selecting a first mode or a second mode; and a controller for causing the recording unit to record the image only when the identifying information is read by the reading means if the first mode is selected, or causing the recording unit to record the image regardless of the reading of the identifying information if the second mode is selected.

Abstract: An image projection apparatus switchable between a reader mode in which an image is projected on a screen for observation and a printer mode in which an exposure position is scan exposed to the image for obtaining a copied image comprises a support member for supporting two scanning mirrors in a mutually perpendicular manner, and a transport member for supporting and transporting the support member for scanning exposure. An arc-shaped guide portion is provided on the support member or on the transport member, whereby the support member can effect a rotating motion on the transport member, about the crossing point of the two scanning mirrors, and the scanning mirrors effect a rotating motion combined with a linear motion at the scanning exposure.
