<p>PURPOSE:To conduct the visual recognition of a sheet size with an ordinary operation posture by providing each indication angle regulating means that can freely set the indication angle of each characteristic means to indicate the size of sheets carried on a sheet housing means. CONSTITUTION:In the case of an image formation device in which a sheet cassette 6 is attachably/detachably furnished into a cassette insertion opening provided at the device front lower portion, size characteristics 12 that act as characteristic means are respectively provided on the front size surfaces of the cassette 6. As for each size characteristic 12, a regulating pin 19 is inserted into any one of plural regulation holes 6b-6d piercingly provided at the sheet cassette 6, and then, by conducting fitting to the turning shaft 6a of the hole 18c of each right and left arm 18b, a characteristic plate 18 is fitted. At this time, the characteristic plate 18 is rotated in a B direction due to self weight, and stopped as the tip of a rib 18d butts against the regulating pin 19, and an indication surface 18a is fixed at the position of an indication angle theta10 in regard to an outer appearance surface 6e (a perpendicular surface), and this angle theta10 is made variable according to the insertion position of the regulating pin 19.</p> |
