    摘要: When the scanner moves over the subject copy, the first reading elements of a close contact type image sensor (1) read the copy. As the movement causes a platen roller (5) to rotate, an encoder ring (4), having a prescribed distinguishing pattern (10) printed within, rotates. Second reading elements configured outside the copy reading range of the close contact type image sensor (1) read the distinguishing pattern, which moves over the reading face as the encoder ring (4) rotates. The second reading elements which read the distinguishing pattern are driven independently of the first reading elements for reading the subject copy, and their reading period is shorter than that of the first reading elements. This configuration enables the moving speed to be accurately detected even when the scanner moves faster than the copy reading speed.

    摘要: An image reading device, particularly a hand scanner, capable of setting a reading position in the main scanning direction accurately at all times. A stage glass is affixed to the reading surface of the hand scanner. A reference line is printed on the stage glass outside of the valid reading range of a CCD (Charge Coupled Device) image scanner. For the adjustment of the valid reading range, the image sensor and a lens are roughly adjusted such that data representative of the reference line appears at the edge of the valid reading range. Subsequently, the valid reading range is electrically shifted in the main scanning direction such that the reference line disappears.

    摘要: An image reading apparatus is provided which is capable of reading an original document at a higher speed. M pieces of lines on the surface of the original document can be simultaneously read by M pieces of line-like strings of light sensing devices making up a CCD (Charge-Coupled Device) having an interval represented by N pieces of lines to be read. When simultaneous reading is completed, the original document is moved to a line existing apart by L pieces of lines from the lines that have been read. While the original document is moving, image signals of lines that have been read are A/D (analog to digital) converted and then stored to memory regions. Simultaneous reading operation and subsequent storing are sequentially performed on lines on which the line-like strings of light sensing devices are placed.

    摘要: An image input apparatus comprises a cold cathode tube light source and a solid imaging device. The image input apparatus reads an image from a document paper by receiving at the solid imaging device a reflected light which is obtained by reflecting a light of the cold cathode tube light source on the document paper. On putting cold cathode tube light source into an on-state, an inverter control circuit controls an inverter to make the inverter supply the cold cathode tube light source with an overcurrent higher than a predetermined tube current which is for use in continuously and stably irradiating a predetermined luminous energy from the cold cathode tube light source. After the overcurrent is applied to the cold cathode tube light source during a predetermined duration, the inverter control circuit controls the inverter to make the inverter reduce the overcurrent to a predetermined current in accordance with an output of the solid imaging device.
