PROBLEM TO BE SOLVED: To increase a capacity of mountable recording sheets at use time and improve space efficiency at non-use time, by providing a height variable in a recording sheet thickness direction of a guide member. SOLUTION: Any of guide members is formed with a height variable in a thickness direction of its recording sheet, here H can take mutually different two values HS, HT (HS<HT). Accordingly, the height H of a hand insertion tray, when it is not in use, is taken as HS to enhance space efficiency of the hand insertion tray, also the height of the hand insertion tray, when it is used, is taken as HT to make a large amount of the recording sheets mountable. In addition, by sliding a slider, the recording sheet in various sizes can be mounted in an upper part of a tray main body with no position deviation.
