ABSTRACT:
A printer case permits paper to be placed in a printer or the ink ribbon to be replaced without the need to remove the cover or the paper shelf. The case comprises a cover mounted on the upper surface of the case and a paper shelf mounted so as to be swingable about its rear end. Projection portions are formed at opposite sides of the upper surface of the shelf. The cover is swingable about its rear end and an opening having a given width is formed between the rear end of the shelf and the front end of the cover such that when the cover and the shelf are opened, the projection portions engage the front end of the cover to maintain the cover and the shelf in an open state.
