Abstract:
1. A sheet size setting device for indicating the size of sheets stored in a sheet cassette and giving identification information of the size to a predetermined sheet size detector, comprising: a first member which includes a tubular holding portion having a first area and a second area in an axial direction and rotatable about an axis, a first indicator held in the first area of the tubular holding portion and adapted to display a first size of the sheets, and a first detectable portion formed in the second area of the tubular holding portion and to be detected for the identification of the first size by the sheet size detector; and a second member which is a member to be assembled with the first member movably in the axial direction of the tubular holding portion and includes an engaging portion to be engaged with the tubular holding portion, a second indicator connected to the engaging portion and adapted to indicate a second size of the sheets, and a second detectable portion to be detected for the identification of the second size by the sheet size detector; wherein: the first member includes a restricting portion capable of restricting a movement of the second member in the axial direction; and the restricting portion restricts the movement of the second member in the axial direction when the tubular holding portion is located at a first rotational position and permits the movement of the second member in the axial direction, thereby causing the second indicator to reach the first area and the second detectable portion to reach the second area, when the tubular holding portion is located at a second rotational position different from the first rotational position.
