    摘要： An image conversion apparatus for converting an image recorded on an original into an electrical signal upon reception of illumination light transmitted through the original, includes a moving device for mechanically moving the original while holding the original, an optical device for focusing the illumination light transmitted through the original on a focal plane as an image, and an image sensor device for converting the image focused on the focal plane into an electrical signal. The moving device and the optical device share a single base, and a shielding device for preventing a lubricant from being scattered from the moving device to the optical device is formed between the moving device and the optical device.

    摘要： An image input apparatus enables image reading at a number of different resolutions including higher and lower resolutions without incurring excessive costs. In the present invention, the image input apparatus includes two scanning states. A first scanning state is achieved by performing film take-up with a take-up spool driven by a DC motor and high-speed image reading during the scan. A second scanning state is achieved by performing film feeding with a scan roller driven by a step motor and lower speed image reading during this scan.

    摘要： An image input device that includes an illumination optical system to illuminate an original with light, a reading unit imaging light transmitted by the original, an original retaining unit retaining the original during a reciprocating motion of the original, and a reciprocating motion guide unit guiding the reciprocating motion of the original retaining unit. The original retaining unit has an aperture portion of a size not covered by the original. Output adjustment of the reading unit is performed in accordance with the light which passes through the portion of the aperture which is not covered by the original. A reciprocating motion guide unit is included to guide the reciprocating motion of the original retaining unit. The original retaining unit has an aperture portion having a first region through which the light of the original is caused to pass and a second region through which light is caused to pass in order for output adjustment of the reading unit. A drive unit causes a reciprocation motion of the original retaining unit in the direction of the optical axis of the light provided by the illumination optical system. An original ejection unit ejects the original and an original holder is slidably retained for insertion and removal in the original retaining unit. The original retaining unit has an aperture portion used by the image input device to perform output adjustment of the reading unit in accordance with light passing through the aperture portion.

    摘要： An image input device having a movable carriage is provided with an origin detection element that moves out of the path of the document when the document is inserted into the carriage. Because the origin detection element moves out of the path of the document, even long documents, such as, for example, long strips of film containing multiple frames, can be read by the image input device without increasing the size of the carriage or of the image input device. The origin detection element includes a tapered edge that functions as a contrast marker. When the edge is located in the path of the light between the illumination source and the image reading device, the edge can be used to cause the generation of a signal by the image reading device to enable the detection of the point of origin of the carriage in the secondary scanning direction and/or in the focusing direction.

    摘要： A scanning device for scanning an original which is set at a predetermined position and has information recorded thereon comprises: a plurality of light emission members for emitting lights of different wavelengths from each other; a first reflection member having a plurality of reflection planes for selectively reflecting emitted lights of a plurality of wavelengths coming from the light emission members and an optical aid portion; a second reflection member for reflecting the lights reflected by the first reflection member to focus them on the original in a linear pattern; and an imaging optical system for focusing the lights of the linear pattern onto a sensor, whereby the sensor receives the information of the original. The device has depressions arranged around the light emission members for reflecting lights and the depressions are shaped differently depending on the wavelengths of the light emissions of the corresponding light emission members so that increased light intensities of the respective wavelengths of light emissions and decreased non-uniformity of the light intensity are attained.
