Abstract

PURPOSE: To prevent breakage of a document due to a jam by temporarily stopping a conveyance mechanism by means of a conveyance control means during detection of the occurrence of lateral displacement of the document by a given amount by means of a detecting means.
CONSTITUTION: Light shield members 25b and 26b of lateral displacement detecting means 25 and 26 are extended in a manner to cross each other at a given angle with a conveyance direction on both sides of a conveyance passage 12. When a document D is protruded outwardly from the conveyance passage, the light shield members are brought into contact with the document D for retraction. During retraction of the light shield members 25b and 26b, limit sensors 25a and 26a are shielded and it is detected that the document D is protruded outwardly from the conveyance passage by a given amount. This detecting information is inputted to a control part 100 containing a CPU, an ROM, an RAM, a switching source, and an inverter. The control part 100 executes processing according to a given program stored in the ROM, and during detection of the occurrence of lateral displacement of the document D by a given amount in the conveyance passage 12 from ON/OFF of the limit sensors 25a and 26a, stops first - third conveyance roller pairs 13, 16, and 17.
