Title: Carrier-related information management system and image reading apparatus
Inventor: TSUJI JUNICHI
IPC: G03B27/46
Filed: 2002-02-21
Abstract: PROBLEM TO BE SOLVED: To provide a carrier-related information management system and an image reading apparatus, which enable easy resetting of correction data. SOLUTION: When a film carrier 38 is mounted in an image reading apparatus main body, a control section 202 reads the identification number of the film carrier 38 from an EEPROM 216 and determines whether or not the identification number corresponds to any of the identification numbers stored in a RAM 208. When correspondence is not found, it determines that the film carrier 38 is mounted in the main body for the first time, and correction data are read from the EEPROM 216 and stored in the RAM 308 with the identification number. Instead of losing the correction data if the substrate 214 is replaced, the correction data stored in the RAM 208 are read from the control section 202 and written into a new EEPROM 216, thereby enabling easy resetting of the correction data.
