ABSTRACT:
A sheet feed control system for use in an image recording apparatus, for example, includes a suction cup for attracting a sheet-like member such as a photographic film under suction, a crank mechanism for moving the suction cup with respect to the sheet-like member, and a swinging mechanism for swinging the suction cup with the sheet-like member attracted thereto to impart swinging action to the sheet-like member. The crank mechanism is drived by a pulse motor in response to a control signal applied thereto, and the swinging mechanism is drived by a pulse motor in response to a control signal applied thereto. Information, such as rotational speeds and angular displacements, with regard to the pulse motors is stored in a memory, and desired information corresponding to certain physical properties of the sheet-like member, can be selected from the memory by the operator. A controller controls operation of the pulse motors to impart appropriate swinging action to the sheet-like member based on the selected information which is read from the memory.
