Abstract

This invention relates to a paper feeding apparatus. The paper feeding apparatus includes a tray, a fixing bracket, and a rolling assembly. The rolling assembly includes a number of rollers rotatably fixed to the fixing bracket to transmit paper to the tray. The paper feeding apparatus further includes a blocking member fixed over the tray and opposite to the rolling assembly. The blocking member prevents one end of the paper, and thus to bent the paper upwardly before falling into the tray.

Description

出紙裝置Paper exit device

本發明涉及一種出紙裝置，尤其涉及一種能夠防止紙張捲曲的出紙裝置。The present invention relates to a paper discharge device, and more particularly to a paper discharge device capable of preventing curling of paper.

辦公設備，如影印機、印表機等，通常具有用於輸出紙張的出紙裝置。使用者在使用該出紙裝置列印高濃度圖案或影像時，由於墨水的特性會造成紙張剛性變弱，尤其是在列印短纖方向的紙張時特別明顯。因此在出紙時，紙張列印完成後會有向下捲曲現象，嚴重時甚至會造成夾紙或紙張破損。Office equipment, such as photocopiers, printers, etc., typically have a paper exit device for outputting paper. When the user prints a high-density pattern or image using the paper discharge device, the rigidity of the paper is weakened due to the characteristics of the ink, especially when printing the paper in the direction of the staple fiber. Therefore, when the paper is ejected, the paper will be curled downward after the printing is completed, and even if it is serious, the paper may be damaged or the paper may be damaged.

有鑒於此，有必要提供一種出紙裝置，能夠有效避免紙張的捲曲。In view of this, it is necessary to provide a paper discharge device which can effectively prevent curling of paper.

本發明提供一種出紙裝置，該出紙裝置包括託盤、固定架以及滾輪組件，所述滾輪組件轉動地固定於固定架上，用於傳送紙張至託盤上，所述出紙裝置還包括固定於該託盤上方並與滾輪組件相向設置的止擋件，該止擋件阻擋由滾輪組件傳送的該紙張的一端，使紙張形成迂回後落入託盤。The present invention provides a paper discharge device comprising a tray, a fixing frame and a roller assembly, the roller assembly being rotatably fixed to the fixing frame for conveying paper onto the tray, the paper discharge device further comprising a fixing device A stopper above the tray and disposed opposite the roller assembly, the stopper blocking one end of the paper conveyed by the roller assembly, causing the paper to form a loop back and fall into the tray.

該出紙裝置出紙時能夠避免出紙時紙張捲曲，有效地提升了列印進的性能。When the paper discharge device discharges the paper, the paper can be curled during paper discharge, and the performance of the printing is effectively improved.

請參考圖1，出紙裝置1包括用於承接紙張2的託盤11、與託盤11大致垂直連接的固定架12、滾輪組件20及止擋件30。該滾輪組件20轉動地固定於固定架12上，用於將紙張2傳送至託盤11上。止擋件30與滾輪組件20相向設置，用於阻擋由滾輪組件20傳送的該紙張2的一端，使紙張2形成向上捲曲後落入託盤11，從而有效避免紙張2落入託盤11時朝下捲曲。Referring to FIG. 1, the paper discharge device 1 includes a tray 11 for receiving the paper 2, a holder 12 that is substantially perpendicularly connected to the tray 11, a roller assembly 20, and a stopper 30. The roller assembly 20 is rotatably fixed to the holder 12 for conveying the sheet 2 to the tray 11. The stopper 30 is disposed opposite to the roller assembly 20 for blocking one end of the paper 2 conveyed by the roller assembly 20, so that the paper 2 is curled upward and falls into the tray 11, thereby effectively preventing the paper 2 from falling downward when it falls into the tray 11. curly.

在本實施方式當中，所述滾輪組件20包括主動滾輪21與從動滾輪22，紙張2自主動滾輪21與從動滾輪22之間被傳送出。In the present embodiment, the roller assembly 20 includes a driving roller 21 and a driven roller 22, and the paper 2 is conveyed from between the driving roller 21 and the driven roller 22.

止擋件30由柔性材料製成，其位於託盤11上方並且包括一固定於固定架12上的固定端31和一自由端32。該固定端31用於將止擋件30固定到託盤11上方，該自由端32正對主動滾輪21與從動滾輪22之間的出紙點大致下方。The stop member 30 is made of a flexible material that is positioned above the tray 11 and includes a fixed end 31 and a free end 32 that are secured to the holder 12. The fixed end 31 is used to fix the stopper 30 above the tray 11, which is directly below the paper exit point between the driving roller 21 and the driven roller 22.

請參考圖2，所述紙張2經主動滾輪21與從動滾輪22傳送至止擋件30時，紙張2的一端受止擋件30的自由端32阻擋及自身重力共同作用而朝上捲曲。當紙張2與自由端32的摩擦力小於其重力時，紙張2落入託盤11內。該止擋件30使得紙張2在出紙時朝上捲曲，可有效矯正紙張2朝下捲曲的現象。同時，止擋件30的阻擋延長了紙張2進入託盤11的時間，使紙張2上墨水變為較幹，進入託盤11後紙張2後也較不容易捲曲。Referring to FIG. 2, when the paper 2 is transported to the stopper 30 via the driving roller 21 and the driven roller 22, one end of the paper 2 is blocked by the free end 32 of the stopper 30 and its own gravity acts to curl upward. When the friction between the sheet 2 and the free end 32 is less than its gravity, the sheet 2 falls into the tray 11. The stopper 30 causes the sheet 2 to curl upward when the paper is discharged, and can effectively correct the phenomenon that the sheet 2 is curled downward. At the same time, the blocking of the stopper 30 lengthens the time when the paper 2 enters the tray 11, so that the ink on the paper 2 becomes relatively dry, and the paper 2 is less likely to curl after entering the tray 11.

儘管對本發明的優選實施方式進行了說明和描述，但是本領域的技術人員將領悟到，可以作出各種不同的變化和改進，這些都不超出本發明的真正範圍。因此期望，本發明並不局限於所公開的作為實現本發明。While the preferred embodiment of the invention has been shown and described, it will be understood Therefore, it is intended that the invention not be construed as being
