    • In a state where a sheet exists, an current I is gradually increased. When an voltage V reaches a light receiving level Vx, the current I at the time is stored as I1. The voltage V immediately before the voltage V reaches the light receiving level Vx is stored as V1. In a state where no sheet exists, the current I is gradually decreased from the above I1. When the voltage V reaches a non-light receiving level Vy, the current I at the time is stored as I2. The voltage V immediately before the voltage V reaches the non-light receiving level Vy is stored as V2. Then, the current I at the time of normal operation is set within a range between I1 and I2. A reference voltage Vs is set within a range between V1 and V2.
    • 在片材存在的状态下,电流I逐渐增加。 当电压V达到光接收电平Vx时,此时的电流I被存储为I1。 紧接在电压V达到光接收电平Vx之前的电压V被存储为V1。 在没有片材的状态下,电流I从上述I1逐渐减小。 当电压V达到非光接收电平Vy时,此时的电流I被存储为I2。 紧接在电压V之前的电压V达到非光接收电平Vy被存储为V2。 然后,将正常工作时的电流I设定在I1和I2之间的范围内。 参考电压Vs设定在V1和V2之间的范围内。
