Abstract: An information processing system encourages a player to continue a game even after the end of a special game state. An information processing system includes a storage device. The information processing system executes a normal game, a special game which is triggered based on a result of the normal game and which is more advantageous than the normal game, and an additional game which is executed after the special game and which includes plural stages. When the shift related to the stages occurs so that the progress of the game reaches the final stage of the stages in the additional game, the information processing system provides an additional reward. Meanwhile, when the progress of the game does not reach the final stage in the additional game, the information processing system stores the current state of the stages into the storage device. The additional game resumes from the stored state of the stages in the next execution.

Abstract: A linkage mechanism between a zoom strobe device and a zoom finder device, which contributes to reduced size of a camera, and can control the illumination range of the zoom strobe device and the magnification of a finder optical system of the zoom finder device. A cam plate is disposed linearly movably in a direction orthogonal to an optical axis of a zoom lens barrel unit. The linear motion of the cam plate changes the magnification of the zoom finder optical system and the range of illumination with strobe light. A linkage member is disposed movable along the optical axis. The linkage member has an engaging portion for being engaged with a cam groove formed in the outer periphery of a drive ring, and moves along the optical axis as the engaging portion moves following the cam groove along with rotation of the drive ring, thereby causing the cam plate to move linearly along the optical axis.
