Abstract
(EN) In the present invention, a sheet-supplying roller part (12) supplies a plurality of bundled sheets (S1) to a transport path (18). An ultrasonic sensor (19) detects a voltage value that changes in accordance with the thickness of the sheets (S1) at a measurement position (P2) on the transport path (18). A determination processing unit (53) determines whether or not a voltage difference in the voltage value for the sheets as detected by the ultrasonic sensor (19) is equal to or greater than a preset threshold value. When it has been determined by the determination processing unit (53) that the voltage difference is equal to or greater than the threshold value, a light quantity adjustment processing unit (54) adjusts the quantity of light with which the sheets (S1) are irradiated from a CIS sensor (23).
(FR) Dans la présente invention, une partie de rouleau d'alimentation en feuilles (12) fournit une pluralité de feuilles groupées (S1) à un trajet de transport (18). Un capteur à ultrasons (19) détecte une valeur de tension qui change en fonction de l'épaisseur des feuilles (S1) à une position de mesure (P2) sur le trajet de transport (18). Une unité de traitement de détermination (53) détermine si une différence de tension dans la valeur de tension pour les feuilles telle que détectée par le capteur ultrasonore (19) est égale ou supérieure à une valeur de seuil prédéfinie. Lorsqu'il a été déterminé par l'unité de traitement de détermination (53) que la différence de tension est égale ou supérieure à la valeur de seuil, une unité de traitement d'ajustement de quantité de lumière (54) ajuste la quantité de lumière avec laquelle les feuilles (S1) sont irradiées à partir d'un capteur CIS (23).
(JA) 給紙ローラー部(12)は、複数枚綴りのシート(S1)を搬送路(18)に給紙する。超音波センサー(19)は、搬送路(18)上における測定位置(P2)において、シート(S1)の厚みに応じて変化する電圧値を検出する。判定処理部(53)は、超音波センサー(19)により検出されるシート(S1)における電圧値の電圧差が予め設定された閾値以上であるか否かを判定する。光量調整処理部(54)は、判定処理部(53)により電圧差が閾値以上であると判定された場合に、CISセンサー(23)からシート(S1)に照射する光の光量を調整する。
