Abstract
A detection piece is held movably, and the size of recording paper being accommodated in a cassette case is detected in correspondence with a positional pattern of a detecting tongue provided on the detection piece. Even in cases where the number of paper sizes to be detected is large, the apparatus is capable of coping with that detection without an increase in the number of detection pieces, and contributes to the simplification of the mounting and demounting operation of the detection piece, prevention of loss or erroneous mounting of the detection piece, and so on.
