を印刷ジョブ終了ごとに切断する切断手段を有する用紙
折りたたみ装置に関するものである。[Detailed Description of the Invention] From ~0 to nnth'-: L to RJF Hirarokoi, NaH [] Pujo '79'L-Juchu V1 Na 4- and paper every time a print job is completed. The present invention relates to a paper folding device having a cutting means for cutting the paper into pieces.
一般に折りたたみ装置においては、用紙受台上に折りた
たみ堆積された用紙をジョブ終了ごとに排出するように
しているが、かかる排出時に印刷装置を一時停止させる
必要があるため、印刷装置の稼動率が低下するという問
題があつた。Generally, in a folding device, the paper folded and stacked on the paper holder is ejected every time a job is completed, but since it is necessary to temporarily stop the printing device during such ejection, the operating rate of the printing device decreases. There was a problem.
このため、ジョブ終了ごとに排出するのを止め、次々と
用紙を堆積することが提案されているが、切断された用
紙の終端が正確かつ確実に折りたたまれないと次の用紙
が折りたたまれないという欠点があつた。For this reason, it has been proposed to stop ejecting the paper after each job and stack paper one after another, but it is said that the next paper will not be folded unless the end of the cut paper is folded accurately and securely. There were flaws.
本発明の目的は、上述した従来技術の欠点をなくし、用
紙終端を正確かつ確実に折りたためるようにすることで
ある。The object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to enable accurate and reliable folding of the trailing edge of a sheet.
本発明は、用紙の終端処理時に用紙受台を通常の折りた
たみ位置より下降させると、用紙の終端が確実に折りた
たまれることに着目し、用紙の終Ｊ端処理時に用紙受台
を下降させるようにしたことを特徴とするものである。The present invention focuses on the fact that the end of the paper is reliably folded when the paper holder is lowered from the normal folding position when processing the end of the paper, and the present invention is designed to lower the paper holder when processing the final J-edge of the paper. It is characterized by the fact that

イドである。FIG. 1 is a schematic diagram of a paper folding device. In FIG. 1, a continuous printing paper 1 discharged from a printing device (not shown) is transported by a tractor 2, and a pair of rollers 3,
The paper is guided to the swing fin 8 through between 13, 4, 14 and 5, 15, folded alternately front and back by the swing fin 8, and deposited on the paper tray 9. 6 and 16 are guides.

て説明する。The rollers 3 and 13 feed the paper 1 at the same speed as the tractor 2, and the rollers 4 and 14 and the rollers 5 and 15 feed the paper 1 at a slightly higher speed than the rollers 3 and 13 so that the paper 1 does not slacken on the way. Suppose you send . It is assumed that the roller 14 is normally positioned upward as shown by the broken line, and when a cutting command is issued, it descends as shown by the solid line. When the roller 14 descends and comes into contact with the roller 4 through the paper 1, the roller 3,
Due to the speed difference between rollers 13 and rollers 4 and 14, tension is applied to paper 1 between them. Thereafter, the paper 1 is cut by lowering the blade 7. The cut paper 1 is sent toward the swing fin 8 by rollers 4 and 14 and rollers 5 and 15. As is well known, the swing fin 8 swings back and forth once when the paper 1 is fed two pages, and the swinging speed is the paper feeding speed of the rollers 3 and 13 before cutting, and the paper feeding speed of the rollers 4 and 14 etc. after cutting. It is controlled in a manner that corresponds to the When the end of paper 1 is processed with paper holder 9 at the normal folding position, paper 1 will be folded as shown in Figure 2.
The terminal end of the terminal is caught between the swing fins 8, and the terminal end can be folded securely. do not have. In FIG. 3, the paper holder 9 is lowered by a distance (L2 - L1) by a drive mechanism (not shown) when processing the end of the paper 1. When the paper holder 9 is lowered, the end of the paper 1 is lowered. It can be folded securely. The control circuit will be explained below with reference to FIG. 4 showing the control circuit.

グを第５図により説明する。When a disconnection command is issued, the monomulti 31 is triggered. The mono multi 32 is triggered at the timing when the Q side output of the mono multi 31 returns to the logical value 1, and during this time, a paper pedestal lowering signal is generated, and the paper pedestal 9 is lowered via the drive mechanism. The monomulti 31 adjusts the descending speed of the paper holder 9 and the cut paper so that the paper holder 9 descends by a desired amount when the end of the paper 1 cut by the cutting command passes through the swing fin 8. The time required for the terminal end of 1 to pass through the swing fin 8 shall be taken into account when deciding. The optical sensor 33 is a sensor for detecting that the paper 1 has completely passed through the swing fin 8, and when the paper 1 has completely passed through the swing fin 8,
The output of the optical sensor 33, that is, the input of the inverter 34 has a logical value of 0, and a flip-flop 37 is set via the differentiating circuit 35 and the inverter 36. As a result, the Q side output of the flip-flop 37 becomes a logical value 11, a paper pedestal rise signal is generated, and the paper pedestal 9 performs a rising operation. The switch 38 is a switch for detecting that the paper holder 9 has reached a predetermined position. When the paper holder 9 has risen to a predetermined position, the switch 38 falls to the normally open contact NO side, and the flip-flop 30 is reset, and the paper holder 9 stops rising. The timing of these operations will be explained with reference to FIG.
前記切断命令により、用紙受台下降信号が発生する。The cutting command generates a paper tray lowering signal.

い。T1, which determines the timing at which the paper pedestal lowering signal is generated, is the operating time of the monomulti 31, and time T2, during which the paper pedestal lowering signal is generated, is the operating time of the monomulti 32. The paper detection signal is an input signal of the inverter 34, and the paper pedestal detection signal is an output signal of the switch 38. In order to improve the operating rate of the printing apparatus, the starting edge processing of the next sheet may be performed while the paper holder is being raised after the trailing edge processing of the paper is completed. Further, the amount by which the paper holder 9 descends when processing the end of the paper 1 may be made variable depending on the page length of the paper 1.
