    • PROBLEM TO BE SOLVED: To properly control normal rotation-reverse rotation in a paper reversing mechanism.
      SOLUTION: An image forming apparatus has a circulating carrying passage including a switchback reversing passage and provided with a plurality of carrying mechanisms, an image forming means for forming an image on printing paper carried in the circulating carrying passage, the paper reversing mechanism arranged in the switchback reversing passage, carrying one surface image-formed printing paper carried at a carrying speed Vr from an upstream carrying mechanism by taking over at the carrying speed Vr and delivering to a downstream carrying mechanism at the carrying speed Vr by starting carrying in the inverse direction after stopping, a printing paper detecting means arranged at the upstream side of the paper reversing mechanism, and a carrying control means for controlling the paper reversing mechanism, and is provided so that the carrying control means starts acceleration to the carrying speed Vr from a stopping state to the paper reversing mechanism after a time T1 calculated based on the carrying speed Vr passes, after the printing paper detecting means detects the printing paper.

    • PROBLEM TO BE SOLVED: To provide a paper feeder enabling reduction in noise.SOLUTION: A paper feeder includes: resist rollers 17 for conveying paper P to a printing section 3 of a printer 1; intermediate conveyance rollers 15 for conveying the paper P to the resist rollers 17; and a control section for performing control so as to start an operation of the resist rollers 17 after stopping the intermediate conveyance rollers 15 when the paper P conveyed by the intermediate conveyance rollers 15 abuts on the resist rollers 17 to form predetermined amount of sag of the paper P and perform assist operation for causing the intermediate conveyance rollers 15 to assist conveyance of the paper P by the resist rollers 17 during the operation of the resist rollers 17. The control section controls the assist operation by the intermediate conveyance rollers 15 so as to leave the sag of the paper P until the rear end of the paper P has passed through the intermediate conveyance rollers 15 while reducing the sag amount of the paper P.
    • 要解决的问题:提供一种能够降低噪音的进纸器。解决方案:供纸器包括:用于将纸张P传送到打印机1的打印部分3的阻挡辊17; 用于将纸张P输送到阻力辊17的中间输送辊15; 以及控制部,用于当由中间输送辊15输送的纸张P抵靠在阻力辊17上时停止中间输送辊15而进行控制,以便开始对阻力辊17的操作,以形成预定量的下垂 纸P,并且执行辅助操作,以使中间输送辊15在阻力辊17的操作期间通过阻力辊17协助纸张P的输送。控制部分通过中间输送辊15控制辅助操作,以便 离开纸张P的下垂直到纸张P的后端通过中间输送辊15,同时减少纸张P的下垂量。
