Abstract: A rotating body has paired anchoring projections and small projections projectingly disposed on one side thereof. On a shutter plate are formed guide holes in which the paired anchoring projections and small projections inserted in the shutter plate are slidable within a predetermined allowance angle range. When rotation input to a handle is broken during rotation input, the shutter plate is rotated respective to the rotating body in a direction opposite to the rotation direction of the rotating body within the allowance angle range, and the light transmission paths are closed by the shutter plate.

Abstract: A controller for a fishing game, in which, when a handle of the controller is rotated, a counter electromotive force is produced between both ends of a generator in the controller. When a short circuit occurs between both terminals, an electrical current which produces a force (that is, a load torque) acting in a direction which prevents rotation of the generator flows between both of the terminals. Therefore, a load torque can be applied to at least the handle without using a driving electrical power supply. When the electrical current flowing between both terminals is controlled through a load-generating device from the side of the body of a game device, a load torque which matches the content of the game being played can be applied to the handle.
