<p>PROBLEM TO BE SOLVED: To surely distinguish which of two re more resistor guides being ready for use and to surely change over the setting position of the resister guides. SOLUTION: This paper feed tray is provided at its side vicinity with a first resister guide (mobile resister guide) 32 which makes its wall 32A abut to the side of the papers, either perpendicular to or flush with a tray surface 13 by turning 90 degrees, and a second resister guide (fixed resister guide) 33 which prevents the wall 32A from tuning more than 90 degrees and also is used to position the side of the papers in a state where the wall 32A becomes flush with the tray surface 13. A spring 45 always holds the position of the guide in use, and a micro switch 47 senses rotating position of the guide.</p> |
