Abstract

PURPOSE:To eliminate the rolling of a sheet by a pile fin and prevent a jam by judging the ream weight of printed sheets by a control part, and lowering a stacker table according to the stacking number of sheet determined by counting the number of printed sheets. CONSTITUTION:The number of toner marks printed every sheet page is detected by a toner mark sensor 1, and counted by a control part 8. As the unit weight is differed according to a difference in sheet ream weight, the stacking number of sheets for turning ON a microswitch 4 is differed according on each sheet ream weight. Thus, a switch lever 5 temporarily fixed by a spring 6 is operated by the weight of stuck sheets 10 to turn ON the switch 4, and the sheet ream weight is judged by the control part 8. The stacking number for lowering a stacker table 3 depending on the kind of the sheet ream weight is stored in the control part 8, and when the ream weight of printed sheets reaches the stacking number for the ream weight stored in the control part 8, the table 3 is lowered. The page count is newly restarted to control the lowering of the table 3.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明はスタッカテーブル降下制御機構に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a stacker table lowering control mechanism.

〔従来の技術〕[Conventional technology]

従来のスタッカテーブル降下制御機構は第３図に示すと
おりであり、連続用紙向はプリンタのスタッカテーブル
は、スタック用紙から受ける反力によってスタック量を
感知して降下させていた。A conventional stacker table lowering control mechanism is as shown in FIG. 3, and in the direction of continuous paper, the printer's stacker table is lowered by sensing the stack amount by the reaction force received from the stacked paper.

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

従って上述した従来のスタッカテーブル降下制御機構は

ＪＡＩＶＩを引き起こす欠点がある。Therefore, in the conventional stacker table lowering control mechanism described above, the stacker table is lowered by sensing the amount of paper stacked by the reaction force received from the stacked paper, so there is variation in the amount of stacks sensed at the same speed of paper, and If the size is small, the pile fins may catch the paper and cause JAIVI.

下を制御する制御部とを有することを特徴とする。The mechanism of the present invention is a stacker table lowering control mechanism in a paper stacking section of a printer that uses continuous paper, and includes a page counting section that counts the number of printed sheets using a page print start pulse, etc., and a detection mechanism section that detects the paper thickness of the paper. and a control section that controls the lowering of the stacker table based on the output of the page count section and paper thickness detection information.

〔実施例〕〔Example〕

第１図は本発明の電子写真プリンタに於ける一実施例で
ある。FIG. 1 shows an embodiment of an electrophotographic printer according to the present invention.

速量の違いで単位重量が異なる為、各用紙速量でマイク
ロスイッチ４をＯＮさせるスタック枚数が異なる。A toner mark sensor 1 detects the number of toner marks printed on each paper page, and a control unit 8 counts the number. Since the unit weight differs depending on the paper speed, the number of stacked sheets required to turn on the microswitch 4 differs for each paper speed.

３の降下を制御する。In addition, the control unit 8 stores the number of stacked sheets to lower the stacker table depending on the type of paper speed, and when the speed of the paper being printed reaches the number of stacked sheets corresponding to the speed stored in the control unit 8, the stacker table is lowered. Lower 3. Then, the page count is restarted and the descent of the stacker table 3 is controlled.

防止できる効果がある。As explained above, in the stacker section of a printer that uses continuous paper, the present invention determines the speed of the paper being printed by the control section and counts the number of printed sheets. This has the effect of allowing the table to be lowered, eliminating paper getting caught in the pile fins, and preventing jams.
