Claim 0:
1. A sheet processing apparatus, comprising:
a sheet storing portion that stores sheets;
a sensing processing portion that senses a length of a stored sheet stored in the sheet storing portion in a sheet conveying direction and a length of the stored sheet in a sheet width direction orthogonal to the sheet conveying direction;
a determination processing portion that determines whether a size of the stored sheet corresponds to any of a plurality of predetermined standard sizes based on a result of the sensing by the sensing processing portion;
an acquisition processing portion that
acquires, when the determination processing portion determines that the size of the stored sheet corresponds to one of the standard sizes, first sheet attribute information narrowed down from sheet attribute information that is predetermined for each type of the sheets and in which a size out of attributes of the sheets is expressed by any of the standard sizes or a combination of the length in the sheet conveying direction and the length in the sheet width direction, the first sheet attribute information being narrowed down based on the standard size that is determined as corresponding by the determination processing portion, and
acquires, when the determination processing portion determines that the size of the stored sheet does not correspond to any of the standard sizes, second sheet attribute information narrowed down from the sheet attribute information based on the result of the sensing by the sensing processing portion;

an acceptance processing portion that outputs the sheet attribute information acquired by the acquisition processing portion and accepts a selection operation of selecting any of the sheet attribute information;
a setting processing portion that sets a processing condition of the stored sheet based on the sheet attribute information selected by the selection operation; and
a switch processing portion that switches, according to a predetermined switch operation, an acquisition function of the acquisition processing portion to acquire the second sheet attribute information when the size of the stored sheet is determined to correspond to one of the standard sizes, between valid and invalid, wherein
the acquisition processing portion is capable of acquiring the second sheet attribute information together with the first sheet attribute information when the determination processing portion determines that the size of the stored sheet corresponds to one of the standard sizes, and
when the determination processing portion determines that the size of the stored sheet corresponds to one of the standard sizes, the acquisition processing portion acquires the second sheet attribute information in a case where the acquisition function is valid and does not acquire the second sheet attribute information in a case where the acquisition function is invalid.
