IMAGE READING APPARATUS

An image reading apparatus, including a feed tray, a conveyance guide, a feed roller, a separator, a reading sensor, and a controller, is provided. The feed tray supports sheets for being fed and has a movable plate movable between a standby position and a feedable position. The feed roller is movable and feeds the sheets to be conveyed along the conveyance guide. A positional relation between the feed roller and an uppermost sheet in the sheets is maintained within a predetermined range by the movable plate located at the feedable position. The controller controls at least rotating-and-stopping movements of the feed roller and the separator and ascending-and-descending movements of the movable plate. While the feed roller feeds the sheets, the controller conducts a vibrating action, in which the movable plate located at the feedable position is moved to ascend and descend for a plurality of times.

A sheet conveying apparatus includes a second conveying roller adjoining a motor driven first conveying roller, a phase determiner to determine a rotational phase of a rotor of the motor, a controller, and a discriminator. The controller controls a drive current flowing through a winding of the motor to reduce phase deviation. The discriminator executes a discrimination regarding one of whether a front end of a sheet has reached a nip portion and whether a rear end of the sheet has passed through a nip portion. The controller controls such that the first conveying roller rotates at a first conveying roller peripheral velocity which is different from a peripheral velocity of the second conveying roller. The discriminator executes the discrimination based on a value of a parameter corresponding to a load torque applied to the rotor where the first conveying roller rotates at the first conveying roller peripheral velocity.

Scanner

A scanner includes a paper feeding roller set, a paper exporting roller set, a scanning module, a background and calibration roller, a main driving assembly, a first sleeve, a torque limiter and a stop-driving assembly. The paper feeding roller set and the paper exporting roller set are driven by the main driving assembly. The background and calibration roller includes a black background section, a white background section and at least one calibration section. The first sleeve sleeves the first end and is linked to the main driving assembly. The torque limiter is disposed between the background and calibration roller and the first sleeve and contacts the same. The stop-driving assembly is selectively abutted against two portions of the background and calibration roller.
