Abstract: Manual operation means controls a motion of an operation target character in accordance with operation data outputted from an input device. Automatic motion control means controls the motion of the operation target character in accordance with a series of pieces of operation data which are prepared in advance. Game control means performs a first process when a first condition is satisfied as a result of control of the motion of the operation target character by the manual operation means only in a predetermined interval in a game in progress, performs a second process which is different from the first process when a second condition is satisfied, and executes the first when the control of the motion is performed by the automatic motion control means in at least a part of the interval regardless of whichever condition is satisfied.

Abstract: A disk unit for a confocal microscope has a rotary disk having many confocal openings, a rotary drive portion, which rotates the rotary disk, a holding member, which holds the rotary disk and the rotary drive portion, a drive portion, which is allowed to insert into and remove from an optical axis the rotary disk, and a disk replacement mechanism, which allows the rotary disk to be attached to and detached from the rotary drive portion.

Abstract: A focus detecting device includes a multi-beam producing member for emitting a plurality of light beams; a light-intercepting member for intercepting a part of the plurality of light beams; a beam splitting member having a surface for reflecting or transmitting an incident light beam; a light-condensing optical system for condensing the incident light beam; and a photodetector having at least two light-receiving sections. The multi-beam producing member and the light-intercepting member are placed on a first path of light, and the light-condensing optical system and the photodetector are placed on a second path of light. The beam splitting member is located at the intersection of the optical axis of the first path of light with the optical axis of the second path of light, and the photodetector is located at a position where the light beam is condensed by the light-condensing optical system.
