Abstract

PURPOSE:To easily switch the discharging direction of the paper in the paper discharging device of a printer stored with paper discharging trays in a main body and used for a copying machine. CONSTITUTION:When paper discharging trays 5, 6 capable of being folded and stored in a main body 1 are opened, a switching knob 8 is operated to switch the reverse discharge and straight discharge of the paper 4. When the paper discharging trays 5, 6 are stored in the main body 1, a guide plate 7 is switched via a restricting plate 9 interlocked at the end section of the paper discharging tray 5 for the reverse discharge of the paper 4, thus the discharging direction of the paper 4 can be easily switched.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper ejection device for a printer used in a copying machine or the like, in which a paper ejection tray can be stored in the main body.

0002

[Prior Art] In recent years, paper ejecting devices have been used to straightly or
Many of them are designed to be switched in two directions, such as inversion. Additionally, some of them have a paper output tray that can be stored in the main body.

[0003] A conventional printer paper ejecting device will be explained below. As shown in FIGS. 3 and 4, the first paper discharge tray 2 is rotatably engaged with the main body 1 so that it can be stored. The second paper discharge tray 3 is rotatably engaged with the paper discharge tray 2 and is foldable. 4 is paper.

[0004] The operation of the printer paper discharging device configured as described above will be described below. First, when the paper 4 is to be reversed and discharged, the first paper discharge tray 2 and the second paper discharge tray 3 are folded and stored in the main body 1, as shown in FIG. In this state, the paper 4 is guided to the paper discharge tray 3 and is reversely discharged. Further, when the paper 4 is to be discharged straight, the first paper discharge tray 2 and the second paper discharge tray 3 are opened and ready for use, as shown in FIG. In this state, the paper 4 is ejected straight without being guided in the reverse ejection direction.

[0005]

[Problems to be Solved by the Invention] However, in the above-mentioned conventional configuration, it is necessary to open and close the paper ejection trays 2 and 3 each time the paper ejection direction of the paper 4 is to be changed, which makes the operation complicated. There was a problem.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and it is an object of the present invention to provide a paper ejecting device for a printer in which a paper ejecting tray can be stored in the main body and the paper ejecting direction can be easily changed. shall be.

[0007]

[Means for Solving the Problems] In order to achieve this object, the printer paper ejection device of the present invention has a switching knob,
A guide plate that changes the paper ejection direction with a switch knob,
It has a structure that includes a paper discharge tray that can be folded and stored in the main body, and a regulation plate that is linked to storage of the paper discharge tray.

[0008]

[Operation] With this configuration, the guide plate can be switched using the switching knob or the regulating plate.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, the first paper discharge tray 5 is rotatably engaged with the main body 1 and can be stored therein. The second paper discharge tray 6 is rotatably engaged with the paper discharge tray 5 and is foldable. 4 is a sheet of paper, 7 is a guide plate operated by a switching knob 8 and has a contact portion 7a formed therein, and 9 is a main body 1.
This is a regulation plate that is slidably attached to the

The operation of the printer paper discharging device configured as described above will be described below.

First, as shown in FIG.
When using the paper 4 in an open state and you want to eject the paper 4 in reverse, move the switching knob 8 to the position shown by the solid line, and switch the guide plate 7 to the position shown by the solid line. lead to the direction of reverse discharge shown in . Also, when you want to eject the paper 4 straight, you can move the switching knob 8 to the position shown by the dashed line and switch the guide plate 7 to the position shown by the dashed line.
is guided in the direction of straight discharge shown by the dash-dotted line. In this way, the direction in which the paper 4 is ejected can be easily switched simply by operating the switching knob 8.

Next, as shown in FIG.
6 is stored in the main body 1, when the paper ejection trays 5 and 6 are stored in the main body 1, the regulation plate 9 pushed by the end of the first paper ejection tray 5 is pushed against the guide plate 7. The position of the guide plate 7 is changed in conjunction with the abutting portion 7a, whereby the paper 4 is restricted to being ejected only in reverse. In this way, the direction in which the paper 4 is ejected can be easily switched in conjunction with the storage of the paper ejection trays 5 and 6 into the main body 1.

[0014]

As described above, the present invention allows the paper ejection tray to be stored in the main body by providing a guide plate that switches the paper ejection direction and a regulation plate that is linked to storage of the paper ejection tray. Furthermore, it is possible to realize an excellent paper ejection device for a printer in which the paper ejection direction can be easily switched.
