Abstract: An image forming apparatus has a paper feeding cassette that selectively stores at least first and second kinds of paper sheets having different sizes with respect to a paper feeding direction. Heights of the paper sheets storable in the paper feeding cassette are set in such a manner that the height of the second paper sheets is lower than the height of the first paper sheets. The apparatus also has a paper feeding tray and a structural member that has a mechanism for feeding third paper sheets loaded on the paper feeding tray. The structural member is disposed in a space of the cassette defined by a difference in the heights.

Abstract: An image forming apparatus comprising: a paper feeding cassette which selectively stores at least two kinds of paper sheets having different size with respect to a paper feeding direction, and includes a posterior end cursor which restricts a posterior end position of the stored paper sheets with respect to the paper feeding direction, wherein the height of the posterior end cursor is changeable. According to this construction, a smaller space is provided to stack large-sized paper sheets which are not frequently used while a larger space is provided to stack small-sized paper sheets which are frequently used can be reserved.

Abstract: A light tunnel retention and adjustment mechanism for retaining and aligning a light tunnel in a light tunnel assembly. The light tunnel retention and adjustment mechanism includes one or more first compliant spring fingers that interface with the light tunnel along a first surface to provide a compliant spring force for adjusting alignment of the light tunnel in a first axis and fixedly retaining the light tunnel in position in the first axis. The light tunnel retention and adjustment mechanism further includes one or more second compliant spring fingers that interface with the light tunnel along a second surface and provide a compliant spring force for adjusting alignment of the light tunnel in a second axis and fixedly retaining the light tunnel in position in the second axis. The light tunnel retention and adjustment mechanism may be formed as a single piece.

Abstract: A DMD stop has a notch through which a light reflected towards other than a projection lens by a mirror unit can pass. This protects the DMD from being heated up and thermally fractured by the light reflected towards other than the projection lens by the mirror unit.

Abstract: In a disc tray (T) having a tray main body (1) to which disc holders (2) are mounted at a plurality of portions in a periphery of a disc set portion, there is provided with a movable connecting member (3) transmitting an opening and closing operation of optional one disc holder (2a) to the other disc holders (2) so as to open and close the other disc holders (2). The movable connecting member (3) can be formed by combining a plurality of rod bodies (31, 32).
