PURPOSE:To stably and rapidly secure papers, by enabling first and second paper guides which are orthogonal to each other, to be secured at arbtirary positions so that papers are held between a rail frame and the first and second paper guides at arbitrary positions. CONSTITUTION:There are provided a rail frame 2 and a rail 3 parallel with sides 1b, 1d of a paper tray 1, and a first paper guide 4 which is parallelly movable and which is in parallel with sides 1a, 1c orthogonal to the sides 1b, 1d. The first paper guide 4 and a second paper guide 5 orthogonal to the former may be secured and released at arbitrary positions, respectively on the frame 2 and the guide 4 by means of fixing levers 40, 50. These orthogonal first and second guides 4, 5 may be secured at arbitray positions by simple lever operation, and therefore, papers having any size may be secured, being surrounded by both guides 4, 5 and the frame 2. |
