BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet discharging device for discharging a conveyed sheet and a recording device using the same.

[0002]

2. Description of the Related Art Today, personal computers and the like have become widespread, and various recording devices for recording the output results have been developed. For such personal use, not only is it required to downsize the device, but it is also required to reduce the installation space.

For this reason, there is a discharge tray for discharging the sheet on which the output result is recorded, which can be pulled out from the main body of the apparatus, and can be stored by pushing the discharge tray into the main body of the apparatus when not in use. With this arrangement, the discharge tray does not protrude when the apparatus is not used, and thus the apparatus installation space can be reduced.

[0004]

However, even when the discharge tray can be stored as described above, the pull-out direction of the discharge tray is constant and cannot be changed.
In order to discharge the sheet using the device, it was necessary to secure a space enough to pull out the discharge tray.

The present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to make it possible to change the state of the discharge tray according to the installation location of the apparatus, so that the discharge tray can be used even in a small installation space. An object of the present invention is to provide a sheet ejection device capable of ejecting a sheet and a recording device using the same.

[0006]

A typical structure according to the present invention for achieving the above object is, in a sheet discharging device for discharging a sheet, a discharging rotating body for discharging the sheet, and the discharging roller. It is characterized in that a discharge tray for receiving the sheet discharged by the rotating body and an adjusting means for adjusting the angle of the discharge tray with respect to the apparatus body are provided.

In the above structure, by adjusting the angle of the discharge tray according to the installation space of the apparatus, the discharge tray can be set to secure the sheet discharge space even in a small space. Can be effectively used.
