Abstract

PURPOSE:To lower the height of a device and confirm the printed face easily by moving printing paper from the paper discharge opening of a printer forward from the horizontal direction to the vertical direction in the diagonally twisted way by a guide plate and discharging it into a tray disposed diagonally to the horizontal direction. CONSTITUTION:Printing paper discharged with its printed face placed downward from the paper discharge opening 45 of a page printer 2 moves along the horizontal part 54 of a guide plate 52 toward a sorting rack 62. When the tip of the paper reaches a raised part 58, the paper moves further forward while ascending in the twisted way and advances up to withdrawn rollers 70. The paper is discharged by the withdrawn rollers 70 into a tray 80 and stacked with the printed face placed upward so that the printed state is confirmed. In the stage of terminating the printing of one sheet, a motor 74 is operated to move the frame body 66 of the sorting rack by one tray. When the paper of the second page is discharged in this state, the printing paper is sorted into a second tray 68 through the same process.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a sorting device suitable for a page printer using the principles of electrophotography.

(Prior Art) Page printers using electrophotography are of extremely high Japanese quality, and are being used for small-scale publishing. In this type of usage, it becomes an important problem to sort the printed paper ejected from the page printer into pages.

For this reason, it is common practice to arrange multiple trays in the vertical direction and to install a sorting device at the paper output port of the printer that moves the trays in the vertical direction according to the pages of the ejected paper. It is being said.

(Problems to be Solved by the Invention) However, since the trays are arranged vertically, the height of the sorting device increases, making it difficult to operate the page printer located at the back of the sorting device. In addition, in a so-called face-down printer that discharges the printed surface downward, there is a problem in that it is difficult to check the printed surface because the printed surface is sorted downward.

The present invention has been made in view of these problems, and its purpose is to provide a page printer that is small in height, has no problems with the ejection form of printing paper, and is easy to check the printed surface. The purpose of this invention is to provide a sorting device.

(Means for Solving the Problem) In order to solve this problem, in the present invention, a fold is made that is inclined with respect to the printing paper ejection direction so that the part connected to the paper ejection port of the page printer is horizontal. A printing paper guide plate that is inclined diagonally upward along a bending line, a plurality of sorting trays that are arranged diagonally in accordance with the inclination of the discharge side of the guide plate, and a plurality of sorting trays that are arranged horizontally according to the number of pages of printing paper. Equipped with means for moving in the direction.

(Function) Print paper ejected from the paper ejection port of Bejib I Nonta,
It is moved forward while being twisted diagonally from the horizontal direction to the vertical direction by a guide plate, and discharged onto a tray arranged diagonally with respect to the horizontal direction. Since the plurality of trays are arranged horizontally, the height of the device is reduced.

(Example) The details of the present invention will be described below based on illustrated examples.

An example of a page printer to which the present invention is applied will now be described with reference to FIG. 2.

Reference numeral 1 in the figure denotes a paper feed device that is removably disposed on the upper part of the page printer main body 2, and in this embodiment, a stacker 3 that stocks printing paper P of two different sizes.
．． 5 and a pickup roller 7.9 for taking out the printing paper pH sheets one by one from these, and from the paper discharge port 11 to the paper feed port 13.
is configured to supply.

A paper detector 15 is disposed below the paper feed port 13 to detect that paper P to be printed is set, and after positioning the leading edge of the paper at a predetermined position, the paper is sent to a printing mechanism to be described later. gate roller] 7.17 is provided.

A photosensitive drum 23 is disposed downstream of the gate roller 17.17 and rotates in the direction of arrow A in the figure, that is, in the direction of moving the printing paper downward, and receives writing from the light beam from the light beam control mechanism 21. Around this photosensitive drum 23, there is a charging device M25 and a developing device! 27 toner sleeves 29, a transfer device 31, a toner recovery device f33, and an eraser 35 are arranged, and a fixing device 378 for fixing the toner transferred to the paper P is arranged roughly below the photosensitive drum 23 to form a printing mechanism. It is configured.

Below the fixing device 37 is a paper ejection roller 43 that ejects the printing paper P from the guide plate 39 to the outside of the apparatus from a paper ejection port 45.
Or is it set up?

In such a page printer, when a print command is output, the printing paper P stored in the stacker part 3.5 provided in the paper feeder 1 is transferred to the pickup roller 7.9.
The paper is pulled out from the paper feed port 13, its leading end is stopped by a gate roller 17, and the paper is roughly fed into the paper so that it curves and activates the paper detector 15. In response to a signal from the paper detector 15, the gate roller 17 rotates in synchronization with the rotation of the photosensitive drum 23 whose surface has toner adhered to it, and the printing paper P is sent toward the photosensitive drum 23. The transfer device N31 charges the back surface of the printing paper P to attract and transfer the toner on the surface of the photosensitive drum 23 to the surface of the printing paper P. The transferred toner is fixed to the printing paper P while passing through the fixing device 37.

The printing paper P that has exited the fixing device M37 is guided by the fixing paper guide 39, reaches the discharge roller 43, and is discharged from the paper discharge port 45 with the printed surface downward, that is, in a so-called face-down state.

FIG. 1 shows an embodiment of the present invention, in which the reference numeral 50 is a sorting device that is a feature of the present invention, and the member indicated by 52 is a paper ejecting device of a page printer. This is a guide plate for transporting paper from an opening 45 to a sorting shelf, which will be described later, and the side attached to the paper output port 45 of the page printer 2 has a horizontal portion 54 formed horizontally so as to be parallel to the surface of the paper being discharged. , consists of a rising portion 58 bent toward the back in the figure along a line 56 so as to rise diagonally upward from the middle, and the end of the rising portion 58 faces a sorting shelf 62 to be described later. As shown in FIG. 3, a pull-in roller 70 is disposed vertically at the rear end of the rising portion 58, and is configured to eject the paper to the sorting shelf 62 by a motor 72.

62 is the aforementioned sorting tank, which includes a frame 66 that is guided by a guide member 64 and moves horizontally and perpendicular to the sheet discharge direction, and a frame 66 that is fixed diagonally to the frame 66 and arranged at equal intervals. It is composed of a plurality of trays 68, 68, 68, .

A motor 74 drives the tray 68 via the frame 66 according to the number of pages. Note that the reference numeral 76 in the figure indicates a guide frame.

In this embodiment, the printing paper discharged from the paper discharge port 45 of the page printer 2 with the printed side facing downward is placed on the guide plate 5.
2 along the horizontal section 54 toward the sorting tank 62.

When the leading edge of the paper reaches the rising portion 58 in this manner, the paper moves upward while being twisted, and advances roughly until it reaches the pull-in roller 70. Pull-in roller 70 discharges the paper onto tray 68 . As a result, the printing paper can be stacked with the printed side facing up (this allows the printing state to be checked).

In this manner, when printing of one sheet is completed, the motor 74 is activated to move the frame 66 of the sorting tank by one tray. When the second page of printing paper is ejected in this state, the printing paper goes through the same process as described above and is transferred to the second tray 6.
It will be divided into 8.

After repeating this process, print the printed paper.
Sort according to the page.
