り出す。That is, the paper 28 ejected from the lower paper ejection port 57 of the first reversing unit 15 is transferred from the second paper feeder 64 to the duplex unit 1.
Enter within 4. The paper 28 that has entered the duplex unit 14 is
The paper is fed by an entrance roller 65 and switched by a switching claw 66. If only one-sided printing is to be performed, the paper passes through a paper discharge conveyance path 67 and is discharged from a second wandering paper roll 69 by a non-discharge roller 68. In the case of double-sided printing, the paper is sent to the discharge gate 70 on the right side in the figure, where the discharge position is selected depending on the paper size and discharged toward the intermediate tray 71. The paper 28 sent to the intermediate tray 71 is moved to a jogger unit 72 also shown in FIGS. 9 and 10, is conveyed by a collapsing roller 73, and is stopped against a stopper 74 with its leading edge aligned. Then, the upper guides 75 and 76 regulate the lifting, and the jogger fence 77 and
78 regulates the width direction position, and the jogger unit 72
Stuck in position. Thereafter, when the stop by the stopper 74 is released at a predetermined timing, the paper 28 stacked at that jogger unit 72 position starts to be re-feeded in the paper re-feeding section 79, and the paper 28 is stopped by the pickup roller 79.
a, passes between the feed roller 79b and the separate roller 79c, and is sent from the re-feeding conveyance path 80 to the sheet feeding conveyance path 41, and then sent by the intermediate roller 39 and ball discharge roller 40 to the first sheet discharge port 42. Then, it is sent out again to the printer main body 10.

であり、軸方向に移動しながら用紙２８を移動する。The job stacker 13 sequentially stacks a large amount of paper 28 ejected from the printer main body 10.
It is configured as shown in Figure 1. That is, duplex unit 1
The paper 28 discharged from the second paper discharge roll 69 of No. 4 enters the job stacker 13 from the paper stack 83. Inside the job stacker 13, there is a job separation function that moves the transport path for each job to selectively shift the stack position of the paper 28, and a paper plate that adjusts the stack amount according to the stack amount so that the top surface of the stacked paper 28 remains constant. It has an elevator function that moves 84 up and down. With these two functions, a large amount of paper 28 is separated for each job and stacked with the surface facing up or down. The paper 28 is moved while moving.

がらそれらに順次両面記録を行う。The illustrated laser printer system uses an interleaf method that alternately records on the other side of a sheet of paper that has already been recorded on one side and records on one side of a new sheet, and during recording, multiple sheets of paper 28 are conveyed at the same time. Record them sequentially. For example, as shown in FIG. 3, the first sheet 28a in the double-sided recording device transfer unit 15, the second sheet 28b returned to the printer main body 10 after single-sided recording, and the second sheet 28b returned to the printer main body 10 after one-sided recording, and the second sheet 28b returned to the printer main body 10 after single-sided recording. 3rd sheet of paper 2 returned to
8c, a fourth sheet 28d that has been reversed after being recorded on one side and sent to the duplex unit 14, and a fifth sheet 28e that is being recorded on one side within the printer main body 10, a total of five sheets are being transported. Double-sided recording is sequentially performed on these sheets 28a to 28e while conveying them.

回復を待つ。By the way, in the double-sided recording apparatus according to the present invention, if there is a signal delay such as an image processing delay or transmission delay on the host side, or a delay in image processing conditions on the apparatus side, the transport of multiple sheets may be delayed as shown in FIG. The paper 28 is once stacked on the jogger unit 72. At this time, the jogger fence 77 and
Leave 78 open. Then, all the sheets 28 on the transport path are sequentially stacked on the intermediate tray 71 from bottom to top. Therefore, the device remains stuck and waits for the signal delay to recover.
