Abstract

PURPOSE:To automatically start to feed without pushing a button, when an original has been inserted, by dividing the time required for rotating a feed roller after inserting the original, to two periods, and executing each different display in the preceding period and in the following period. CONSTITUTION:When a sheet original 2 is inserted between a pickup roller 3 and a feed roller 4, an original existence sensor 11 detectes it, makes the first timer count the time for a prescribed time, and after a constant time t1, a pickup roller 3 falls at the feed start position. After that, by the time counting of the second timer, the pickup roller 3 starts to rotate after a constant time T2 has elapsed, and at this time, the sheet original 2 starts to be carried. When each different display is executed in the course of time counting operation of this first timer and the second timer, a replaceable state of the original 2 and an unreplaceable state are displayed separately, and are informed to an operator.
