Title: Image reader
Inventor: MORIYA SHIGERU
IPC: H04N1/04
Filed: 1989-02-17
Abstract: PURPOSE:To enable a copy to be taken if a step-out is fine by judging whether or not the extent of the step-out is a value where an image can be read under restricted conditions where a step-out hardly occurs in judging the step-out by a comparing means by detecting the extent of the step-out. CONSTITUTION:A scanner 10 is moved actually at certain timing, the number of movement steps from the scan starting home position to the position where a sensor 100 turns on is counted, and the range is found. At this time, the scanner 10 is driven at the speed which is slow enough not to cause a step-out and whether the scanner 10 is in a step-out state or not is judged from the difference between the found range and predetermined value. Thus, a scanner position detecting means detects the difference of the scanner from a specific initial position, i.e. the extent of the step-out, the comparing means decides the extent of the difference, and a scan condition restricting means judges whether or not the image can be read under the restricted conditions where the step-out hardly occurs. Consequently, when the step-out is fine, the image can be read under the conditions where the step-out hardly occurs.
