Title: Handy type image reader
Inventor: KUSUTAKI IZUMI
IPC: H04N1/107
Filed: 1987-07-03
Abstract: PURPOSE:To eliminate disorder in a reading direction and duplicated reading, by only reading an image when an original is scanned in one direction, and starting the reading of the image at a part where scan is performed in an opposite direction after a scanning distance in one direction becomes equal to that in the opposite direction. CONSTITUTION:In a two-phase type rotary encoder 8, the travel direction and scanning speed of a main body are detected by a scan direction detection circuit 25 and speed detection circuit 26. Also, the encoder 8 is connected to a CPU20 via an I/O 23, and the number of pulses of the encoder is counted, and it is stored in a count C in a RAM22. When the main body is scanned in one direction after being scanned in the opposite direction along the original, the scan of the original in one direction is discriminated, and the set state of the flag F of the RAM22 is discriminated. At this time, since the main body is scanned in the opposite direction once and the flag F is set, the number of pulses in which the scanning distance in the opposite direction is stored is decremented by the number of pulses generated in the scan in one direction. After completing decrement, a distance is decided as '0', and the flag F is reset, then, the reading of an original image is started.
