Claims (1)

【実用新案登録請求の範囲】[Scope of utility model registration request] 底板を上昇させることにより底板上の用紙を上昇させ、
この上面が給紙ローラに当接する位置で高さ検知手段の
出力により底板の上昇を停止させるよう制御した給紙装
置において、用紙上昇過程で、この用紙の残量を段階的
に検出し、その段階的に検出された信号により残量を表
示しかつ上昇手段の印加電圧のレベルを制御する様にし
たことを特徴とする給紙制御装置。By raising the bottom plate, the paper on the bottom plate is raised,
In a paper feeding device that is controlled so that the bottom plate stops rising at the position where the top surface contacts the paper feeding roller by the output of the height detection means, the remaining amount of paper is detected step by step during the paper rising process, and the remaining amount of paper is detected step by step. A paper feeding control device characterized in that the remaining amount is displayed using signals detected in stages and the level of the voltage applied to the raising means is controlled.
