Abstract
A data processing apparatus including a drawable hopper table with a hopper and an image reading head. Sheets are conveyed from the hopper to a stacker arranged below the hopper table, and the stacker includes a pusher for discharging sheets. The hopper table and the pusher are moved by a common motor and a gear mechanism. The gear mechanism includes a partially toothed gear, so as to drive one of the hopper table and the pusher. A cam mechanism is incorporated with the gear mechanism to prohibit the movement of the not driven one. Also, a top cover is pivotally attached to the hopper table about a pivot arranged on one side of the top cover remote from the hopper, the image reading head is pivotally attached to the top cover about a fulcrum arranged on one side of the top cover near the hopper.
