  • Patent number: 5754315
    Abstract: An image input system includes an image input device having a movable carriage and a feeder removably attached to the image input device. The image input device performs a reading action of image information from a source document loaded onto the carriage. The image input device uses a single opening for loading and discharging the film mounts to prevent double loading. The feeder loads the source document onto the carriage during a loading action and discharges the source document from the image input device during a discharging action. A controller controls the operation of the image input device and the feeder. The controller operates a detection system to detect the presence of a film mount remaining in an image input device.

  • Patent number: 5742326
    Abstract: An image reading device and method for producing a uniformly focused light image on a source document includes a document mount, an imaging device, and a drive assembly for moving at least one of the mounting device and the imaging device in a secondary scanning direction. The image reading device includes a control circuit for establishing multiple designated positions on the source document in the primary scanning direction and in the secondary scanning direction and for calculating the focus position from a signal output from the imaging device for the multiple designated positions. A cam member can be provided to adjust the position of the document mount along the optical axis of the light striking the document, a cam surface of the cam member contacting the document mount.

  • Patent number: 5589953
    Abstract: An image input system includes an image input device for reading image information from a source document and a feeder for automatically inserting the source documents into the image input device. The feeder includes a loading magazine storing source documents and an adjacent discharge magazine storing source documents discharged from the image input device. The source documents travel along a transport surface within the feeder. A dividing board controls the position of the source documents within the feeder. Detectors are provided to monitor the loading operation. A method of reading image information using the image input system is also disclosed.
