Abstract

PURPOSE:To read information on a keyword with no error by controlling an image reading means so that only the display range of retrieving information displayed at a position corresponding to the size of a form is read based on a signal received from a form size detecting means. CONSTITUTION:A control part 5 prescribes a reading area from the detected form size in case the form sent to an image reading part 1 is equal to a mark sheet form 2 and also checks whether the form 2 is set correctly at a prescribed position of the part 1 based on a check mark put on the form 2. When the form 2 is sent correctly, the mark position of the keyword of the form 2 is sent correctly, the mark position of the keyword of the form 2 is decoded. Then the keyword mark is converted into code information from the mark position. This code information is temporarily stored in a RAM 4. When the code information equivalent to an item is stored in the RAM 4, the code information on the from 2 is recorded on a memory part 7. Then a read form 3 is read by the part 1 and recorded n the memory part 7 for each page to be combined with the code information.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention is capable of sequentially optically reading, recording and storing image information of a large number of sheets of reading paper, and extracting image information of individual reading sheets as necessary.
