    • A sheet storing apparatus for stacking sheets discharged from a printer and storing the sheets therein, the apparatus having a plurality of trays, separate driving systems of the trays, and a detector for detecting failure in sheet storing operation on each of the trays. When the detector detects failure in sheet storing operation on one of the trays, successive sheets are transported to another tray. Further, each of the trays has a mechanism for moving the tray horizontally and a mechanism for moving the tray vertically, and the movements of the trays are independent. When it is detected that one of the trays has trouble in its horizontal movement mechanism and/or vertical movement mechanism, sheets are received on the other trays.
    • 一种片材存储装置,用于堆叠从打印机排出的片材并将片材存储在其中,该装置具有多个托盘,托盘的独立驱动系统以及用于检测每个托盘上的片材存储操作失败的检测器。 当检测器检测到其中一个托盘上的纸张存储操作失败时,连续的纸张被运送到另一个纸盘。 此外,每个托盘具有用于水平移动托盘的机构和用于垂直移动托盘的机构,并且托盘的运动是独立的。 当检测到其中一个托盘在其水平移动机构和/或垂直移动机构中具有麻烦时,纸张被接收在另一个托盘上。

    • Disclosed is a sheet storing apparatus with a sheet tray which is movable up and down. When the tray moves down to a position which is specified according to the sheet size, fullness of the sheet tray is judged. The sheet storing apparatus has a sheet sensor for detecting a sheet on the tray and a top surface sensor for detecting the upper surface of the tray on which sheets are to be stacked or the top surface of a sheet stack on the tray being at a specified position. A specified time after the sheet sensor detects no sheets, the tray starts moving up, and the upward movement of the tray is stopped when the top surface sensor generates a detection signal. The sheet storing apparatus further has a paddle wheel for aligning sheets transported onto the tray. A specified time after the top surface sensor generates a detection signal in a situation that the sheet sensor detects a sheet, the tray starts moving down.
    • 公开了一种具有能够上下移动的片材托盘的片材存储装置。 当托盘向下移动到根据片材尺寸指定的位置时,判断片材托盘的丰满度。 片材存储装置具有用于检测托盘上的片材的片材传感器和用于检测托盘的上表面的顶表面传感器,其中片材将被堆叠在其上,或者托盘上的片材堆叠的顶表面处于指定的位置 位置。 在纸张传感器检测不到纸张之后的指定时间内,托盘开始向上移动,并且当顶表面传感器产生检测信号时,托盘的向上移动停止。 片材存储装置还具有用于对准输送到托盘上的片材的桨轮。 在表面传感器检测到纸张的情况下,表面传感器产生检测信号之后的指定时间,托盘开始向下移动。

    • An image forming apparatus provided with a control circuit disposed at a front position of transfer section for correcting the timing of signal emission for turning on register rollers and also for starting exposure for image formation. The control circuit corrects the timing of signal emission basing on the time measured from signal emission to the time when the leading edge of a paper sheet reaches a sensor disposed at a rear position of the register rollers. The correction is made every time when a predetermined number of sheets are fed or an average value based on a predetermined number of samplings is obtained or power supply is turned on. The correction is further made by memorizing the data practically measured on the number of sheets fed to the transfer section from each one of paper feed positions.
    • 一种图像形成装置,设置有控制电路,该控制电路设置在传送部分的前部位置,用于校正用于打开对准辊的信号发射定时,并且还用于开始图像形成曝光。 控制电路基于从信号发射测量的时间到纸张的前端到达设置在对准辊的后部位置的传感器的时间来校正信号发射的定时。 每当进给预定数量的纸张时,进行校正,或者获得基于预定数量的采样的平均值或电源接通。 进一步通过记录从每个送纸位置馈送到转印部分的纸张数量实际测量的数据进行校正。
