    • A sheet passage is formed so as to extend from a sheet feed position via a printing position to a sheet delivery position, delivery rollers driven by a driving unit are disposed between the printing position and the sheet delivery position on the sheet passage, pressure rollers are disposed on one side of the sheet passage so as to be in contact respectively with the delivery rollers disposed on the other side of the sheet passage, a back sheet guide is disposed between the delivery rollers and the sheet delivery position, and a printed sheet delivered by the delivery rollers and guided by the back sheet guide is transferred to a printed sheet storage unit by sheet transfer arms. Thus, the time required to transfer the printed sheet from the delivery rollers to the printed sheet storage unit is extended so that the time between the delivery of the preceding sheet to the printed sheet storage unit and the delivery of the succeeding sheet to the printed sheet storage unit is extended to prevent the smearing of the preceding printed sheet previously stored in the printed sheet storage unit with the ink by the succeeding printed sheet.
    • 片材通道形成为从片材进给位置经由打印位置延伸到片材输送位置,由驱动单元驱动的输送辊布置在片材通道上的打印位置和片材输送位置之间,压力辊是 设置在片材通道的一侧,以分别与布置在片材通道另一侧的输送辊接触,底片引导件设置在输送辊和片材输送位置之间,并且输送的印刷品 通过输送辊并由背板引导件引导由纸张传送臂传送到打印纸存储单元。 因此,将印刷纸从输送辊转印到印刷纸张存储单元所需的时间延长,使得在前一张纸到印刷纸张存储单元的传送之间的时间和后续纸张传送到印刷纸张 存储单元被扩展以防止先前存储在打印纸存储单元中的前一印刷纸张与后续印刷纸的油墨拖延。

    • A paper feeding apparatus of the present invention, in which it is adapted such that a paper tray holding plural sheets of paper in a pile is supported by a fulcrum for rotation round the same and the paper tray is rotated by a paper setting mechanism so that the topmost copy paper of the paper held in the paper tray is brought into abutment with a feed roller and fed to a printing portion. As the drive power source of the paper setting mechanism and the feed roller, a constituent of a paper feeding mechanism, is used only a single motor rotatable in both normal and reverse directions. The normal or reverse rotation of the motor is selectively transmitted by a drive gear mechanism to the paper setting mechanism or the paper feeding mechanism, and thereby, it is made possible to selectively drive either the paper setting mechanism or the paper feeding mechanism using only a single motor. Thus, it is made possible to make the apparatus smaller and to reduce the cost of parts.
    • 一种本发明的送纸装置,其特征在于,其适于使得在纸张中保持多张纸的纸托由支撑件支撑在其周围旋转,并且纸盘由纸张设置机构旋转,使得 保持在纸盘中的纸张的最上面的复印纸与进给辊抵接并供给到打印部分。 作为纸张设置机构的驱动电源和进给辊,供纸机构的组成部分仅使用可在正向和反向两个方向上旋转的单个电机。 电动机的正转或反向旋转通过驱动齿轮机构选择性地传递到纸张设置机构或供纸机构,从而可以仅使用纸张设置机构或送纸机构来选择性地驱动 单电机。 因此,可以使装置更小并降低部件的成本。
