An original reading apparatus can realize stepwise or sequential variable magnification using relatively small size optical system upon reading an original. The apparatus includes a first mirror arranged in an optical path from a reading position of an original to an image forming portion across an image forming lens and reflecting a light from the reading position of the original, and a second mirror arranged with placing a reflection surface in opposition to a reflection surface of the first mirror and reflecting a light reflected from the first mirror for a plurality of times between the first and second mirrors, and thereafter reflecting toward the image forming lens. A mirror angle positioner for varying an angle of the reflection surface of at least one of the first and second mirrors depending upon a designated original reading magnification.

Variable magnification reflecting mirror apparatus

A reduction optical system including a lensand a mirror, a CCD image sensorand a frame including a frame memberfor accommodating the reduction optical system and the CCD image sensor are integrated to constitute an image reading unit, and the unitis covered with a cover member. A lampis provided on the cover memberand spatially isolated from the inner space of the unit. A slitof the cover memberis closed by a transparent memberThe lampemits the lightonto a documenton a document setting glass, and the reflected lightfrom the documententers the CCD image sensorthrough the transparent member, slit, slit', mirrorand the lensand is converted into electrical information, thereby reading image information of the document

Image reading apparatus

A scanning module of the present invention includes a light source for illuminating a document. Light reflected by the document is incident to a first and a second mirror provided in a pair. The two mirrors reflect the light a plurality of times therebetween and then output it as light reflected from the first mirror. Subsequently, a third and a fourth mirror sequentially reflect the light along a path including a lens. A fifth mirror reflects the light incident thereto from the lens. A linear sensor is spaced from the fifth mirror by a preselected distance such that the light passed through the lens is focused on the linear sensor. The first and second mirrors are adjustable in position on a path, extending from the document to the first mirror, while maintaining a positional relation therebetween.

In a wire-driving system that drives and moves a movable unit along a guide path, a drive drum member is rotatably provided on the movable unit to be rotated around an axis which is perpendicular to a movement direction of the movable unit. An electric drive motor is provided in the movable unit and operationally connected to the drum member to be rotationally driven in either a first rotational direction or a second rotational direction. A wire cable has a first end and a second end, and is partially wound around the drum member such that a first cable section and a second cable section are extended from the drum member. The respective first and second ends of the wire cable are securely attached to two fixed points beside terminal ends of the guide path such that the first and second cable sections of the wire cable are tensionally extended along the guide path. The respective first and second cable sections of the wire cable are wound around and unwound from the drum member during the rotation of the drum member in the first rotational direction by the drive source, and the respective first and second cable sections of the wire cable are unwound from and wound around the drum member during the rotation of the drum member in the second rotational direction by the drive source, resulting in the movement of the movable unit along the guide path.

A toner bottle has a protruding portion on a lateral side of the toner bottle and an incised groove is provided in a bottle holder, and both of them are composed to be removable and to rotate integrally. The incised portion is provided in a position where a toner delivery outlet of the toner bottle is rotated slightly from the state of facing straight up and where the protruding portion of the toner bottle may pass through. That is, according to the relative positioning of the protruding portion of the toner bottle and the incised portion of a ring member, the toner is prevented from spilling out of the toner delivery outlet of the toner bottle by regulating a removable attitude of the toner bottle with respect to the bottle holder.

A similar document retrieval method capable of realizing an improved retrieval performance. In this similar document retrieval method for retrieving similar documents of a reference document from a plurality of retrieval target documents, similarities of each one of the plurality of retrieval target documents with respect to the reference document are calculated by using each one of two or more similarity calculation methods separately, and the similar documents of the reference document are retrieved by carrying out a discrimination analysis with respect to each one of a plurality of similarities calculated by using each one of the two or more similarity calculation methods separately.
