<p>PURPOSE:To achieve correct detection by detecting a pattern body position corresponding to the positions of paper size guides through ON-OFF operation of a switch. CONSTITUTION:The position of a pattern body 19 which is attached to paper size guides 12a, 12b and moves in response to the paper size is detected through ON-OFF operation switches 23a to 23c by means of convex and concave parts 20, 21. This allows the paper size to be correctly.</p> |
