Abstract

PURPOSE:To readily remove a jammed paper without reducing the number of paper feed cassettes by setting a paper piling direction nearly vertical and providing a means which inverts a circulator and piles and feeds sheets on the opposite side to the paper feed side of paper feed cassettes. CONSTITUTION:The means 24 which inverts a circulating route used for double- sided recording and piles and feeds sheets is provided on the opposite side to the paper feed side of the paper feed cassettes 1 to 4 by setting the paper piling direction nearly vertical. Consequently, the recorder is designed to be compact, and the means 24 does not occupy the disposing place of the paper feed cassettes 1 to 4, so that the opposite side to the paper feed cassettes 1 to 4 of the means 24 can be used for a place to remove a jammed paper. Thus, a jammed paper can be readily removed without reducing the number of disposed paper feed cassettes.

As a recording device capable of double-sided recording as described above, the circulation path is reversed to perform double-sided recording. Japanese Patent Laid-Open Publication No. 114227/1983 discloses a device in which the loading and unloading means are stacked one on top of the other in the same way as multistage paper feeding cassettes. Such a recording device uses a reversal of the circulation path. Not only is there a problem in that the number of paper feed cassettes is reduced by the number of paper feed cassettes provided, but also the reversal. Another problem is that when a jam occurs in the loading and unloading means, it is troublesome to remove the jammed paper. Inversion.
If a jam occurs in the loading and unloading means, it is almost impossible to remove the jammed paper unless it is reversed and the loading and unloading means is pulled out in a horizontal direction perpendicular to the paper feeding direction. Paper is easily damaged.

Furthermore, when double-sided printing is selected on the control panel, the number of sheets to be printed, the paper size, etc. are also selected, and printing is started, the double-sided printing operation is performed as follows. That is, when double-sided recording is selected, the single-sided and double-sided switching gate 21 is switched to the dotted line position to open the passage to the circulation path and close the passage to the discharge port 22, and the receiving/discharging switching gate 23 is switched to the dotted line position. By switching to the clockwise rotating position and selecting double-sided recording and paper size, the lower end regulating plate 24f is brought to a position corresponding to the paper size as described above. Then, the toner image is transferred and fixed onto the paper sent out from one of paper cassettes 1 to 4 in the same way as in the case of single-sided recording, but in this case, the single-sided recording paper enters the circulation path and rolls around the entrance roller. 24a in the feeding direction and guidance of the elastic guide 24i, the loading and unloading means 2
It is sent onto the tray 24d of No. 4. This feeding is performed a specified number of times, and when it is finished, the single-sided, single-sided, double-sided switching gate 21 is switched to the clockwise rotation position indicated by the solid line.
At the same time as the receiving/discharging switching gate 23 is switched to the solid line position, the entrance roller 24g, relay conveyance roller 25, etc. begin to rotate in the discharging direction. Therefore, the tray driving means 24e rotates the tray 24d counterclockwise to press the single-sided recording paper against the feed-out roller 24b, and as the feed-out roller 24b rotates to feed out the paper in the counterclockwise direction, the single-sided recording paper is reversed and 8F is inserted. Feeding means 24
One piece will be sent out.
