ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a printing apparatus having a top cabinet which can be opened/closed and, more particularly, to a printing apparatus with a rotatably attached paper feed cassette.
2. Description of the Background Art
Printing apparatuses for printing on cut sheets of paper in which a plurality of cut sheets of paper are put in a paper feed cassette and the cut sheets of paper are separated and fed one by one from the paper feed cassette for printing have been widely used. In this type of printing apparatus, generally, the paper feed cassette is placed at an upper rear part of the printing apparatus, and the printed cut sheet is discharged to the front side of the paper feed cassette.
One example of the printing apparatus having the paper feed cassette containing the cut sheets is a printing apparatus of thermal transfer system. When an ink ribbon used in the thermal transfer type printing apparatus is to be exchanged, it is necessary to open by rotating rearward the top cabinet of the printing apparatus to change the ink ribbon. When the top cabinet is rotated rearward, paper feed cassette moves rearward together. Therefore, it is necessary to ensure a space behind the printing apparatus so that the paper feed cassette does not hit anything behind. Therefore, an extra space has been necessary for installing the printing apparatus.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a printing apparatus allowing opening/closing of the top cabinet without requiring extra space in the rear side.
Another object of the present invention is to provide a printing apparatus capable of preventing troubles such as a paper jam.
According to an aspect, the present invention provides a printing apparatus including an apparatus body for printing on a sheet of recording paper, and a paper feed cassette attached rotatably over a prescribed range within the apparatus body for feeding recording paper to the body of the apparatus.
The paper feed cassette is attached rotatable over a prescribed range in the body of the apparatus and therefore, even when the printing apparatus is placed without sufficient space therebehind, the top cabinet can be opened/closed freely.
According to another aspect, the present invention provides a printing apparatus including an apparatus body for printing on a sheet of recording paper, and a paper feed cassette attached rotatably over a prescribed range within the body of the apparatus for feeding the recording paper to the body of the apparatus, with the apparatus body including a recording paper discharging unit for discharging the printed sheet of recording paper, and a rib provided near the recording paper discharging unit for bending the direction where the printed recording paper proceeds.
As the paper feed cassette is attached rotatable over a prescribed range in the body of the apparatus, the top cabinet can be opened/closed freely even when the printing apparatus is placed without sufficient space therebehind. Further, as the apparatus body includes a rib for bending the direction of progress of the printed recording paper, troubles such as a paper jam can be prevented.
The foregoing and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings.
