Abstract: A sheet material conveying apparatus is provided with retard levers for supporting a retard roller shaft, which are rotative centering on the central axis of rotation so as to press the retard roller to a conveying roller. Retard pressing springs are hooked to the spring latches of the retard levers, and the hooks of a slider. When the limiter gear of a torque limiter rotates, the tightening force exerted by a stepped spring against an inner race is caused to change, thus changing the rotating-load torque of the retard roller. A motor enables the limiter gear to rotate, while moving the slider up and down. In this way, it is made possible to change the rotating load torque of the retard roller, while changing the pressurized contact force of the retard roller against the conveying roller. With the structure thus arranged, it is attempted to make the life of rollers longer, and to prevent the occurrence of double feeding of sheet material.

Abstract: A reliable detection of optically detecting the type of recording media is achieved. A part of a support member for supporting an optical sensor is pushed against the surface of a sheet by a spring so as to maintain the gap between the sensor and the sheet surface. With this arrangement, a recording apparatus which is free from wrong detection is achieved regardless of a gap-varying factor, that is, the remaining amount of sheets. Also, by arranging a part of a light-shielding hood so as to abut against the sheet, wrong detection due to disturbance light can be prevented.
