<p>PROBLEM TO BE SOLVED: To prevent mixture of a sheet discharged earlier and a sheet discharged later on a paper discharge tray. SOLUTION: A pair of insertion holes 5, 5 formed on a back surface 4 which is one of a plural number of erected outer surfaces of a printer 1. Additionally, projected parts 14, 14 to insert into the insertion holes 5, 5 are formed on one end of an extension tray 12 free to draw out and remove which is usually stored in the paper discharge tray 11. It is possible to prevent mixture of the sheet discharged earlier on the paper discharge tray 11 and the sheet discharged later by removing the extension tray 12 from the paper discharge tray 11, inserting the projected parts 14, 14 into the insertion holes 5, 5, holding them on a back surface 4 and carrying out following printing after moving the sheet on to the extension tray 12 when the sheet discharged earlier exists on the paper discharge tray 11.</p> |
