IMAGE READER

PROBLEM TO BE SOLVED: To provide an image reader reading an original by performing preparation operation in a preparation parallel control system, based on original change time data at an automatic original conveyance mechanism section. SOLUTION: A scanner 1 acquires the original change time data in an entire original conveyance mode from an ADF4 at start-up, refers to the acquired original change time data based on the original conveyance mode of the read conditions of the read operation in read operation, and performs preparation operation, by performing preparation operation in the preparation parallel control system, thus continuously performing the preparation operation in the preparation parallel control system at an appropriate timing, without changing a program, even if the ADF4 is replaced with an ADF4 that has different control timing, and hence reading of the original can be made quickly and appropriately.
