    • An image forming apparatus includes: an apparatus body, a paper feed cassette, a feed section, an operation control section, a paper passage detection sensor, a cassette attachment-detachment detection sensor, a paper presence-absence detection sensor, a sensor failure determination section, and an alarm control section. The paper passage detection sensor detects whether or not paper has passed through a position. The cassette attachment-detachment detection sensor detects attachment or detachment of the paper feed cassette. The paper presence-absence detection sensor detects paper absence when the paper feed cassette is withdrawn from the apparatus body. The sensor failure determination section determines that the paper presence-absence detection sensor is in failure. The alarm control section, when passage of the paper is not detected before passage of a predefined time period, alarms that the feeding of the paper has failed.
    • 图像形成装置包括:装置主体,供纸盒,进纸部,操作控制部,纸通道检测传感器,盒安装拆卸检测传感器,纸张存在检测传感器,传感器故障判定 部分和报警控制部分。 纸通过检测传感器检测纸张是否通过位置。 盒式磁带安装拆卸检测传感器检测供纸盒的安装或拆卸。 纸张存在检测传感器检测到供纸盒从设备主体中取出时纸张不存在。 传感器故障确定部确定纸张存在检测传感器失败。 报警控制部分在通过预定义的时间段之前未检测到纸张通过时,报警纸张的进纸失败。

    • The object of the present invention is to obtain a contact pressure control device capable of carrying out feedback control enduring a practical use by inventing a pressure detecting means and the employment structure of the same. The contact pressure control device of the take-up winder comprises a bobbin holder 5, a contact pressure roller 11 contacted against the bobbin B set on the bobbin holder 5, a slide supporting mechanism (s) for supporting the contact pressure roller 11 elevating or descending to the machine main body 2 , and a contact pressure cylinder 13 freely adjusting the contact pressure of the contact pressure roller 11 and the bobbin holder 5. Moreover, a load cell 16 is provided directly below one contact pressure cylinder 13 located between a pair of slide supporting mechanisms (s), (s). Furthermore, a print circuit board for controlling is provided for controlling the contact pressure cylinder 13 based on the detected value of the load cell 16 so that the contact pressure is to be maintained at a designated value.
    • 本发明的目的是获得一种接触压力控制装置,该接触压力控制装置能够通过发明一种压力检测装置和其使用结构来实现持续实际应用的反馈控制。 卷取卷取机的接触压力控制装置包括筒管架5,与筒管架5上设置的筒管B接触的接触压力辊11,支承接触压力辊11的滑动支承机构, 下降到机器主体2,以及接触压力缸13,其自由地调节接触压力辊11和筒管架5的接触压力。此外,测力传感器16直接设置在位于一对之间的一个接触压力缸13的下方 的滑动支撑机构(一个或多个)。 此外,提供了一种用于控制的印刷电路板,用于基于测力传感器16的检测值来控制接触压力缸13,使得接触压力保持在指定值。
