Binoculars including a pair of lens barrels, each lens barrel having an optical system, a relative movement between the lens barrels causing the lens barrels to relatively displace, traveling between a closed state and an operational state in which eye spacing adjustment is enabled, a barrier that is moved between an optical system protective position with the lens barrels in the closed state and a retracted position with the lens barrels in the operational state, and a barrier control member, mounted on the lens barrels which moves the barrier from the optical system protective position to the retracted position in response to the displacement of the lens barrels from the closed state to the operational state.

Binoculars having lens barrels movable between open and closed states by pivotal movement

Binoculars include a pair of lens barrels, each barrel having an optical system, a flexible lens barrier which travels between a protective position for protecting the optical system of each of the lens barrels and a position that is retracted from the field of view of the optical system, and a drive member for moving the flexible lens barrier between the protective position and the retracted position.

Binoculars

Binoculars which can adjust the optical axes of optical systems by moving at least one lens groups of objective lens groups and eye piece groups in a plane approximately perpendicular to the optical axes of the lens groups and further independently adjust the optical axes of the optical systems in a linear direction and in the direction approximately perpendicular to the linear direction by moving, one lens groups of the objective lens groups and the eye piece groups on the plane approximately perpendicular to the optical axes of the lens groups approximately in the linear direction and moving the other lens groups of the objective lens groups and the eye piece groups on the plane approximately perpendicular to the optical axes of the lens groups approximately in the linear direction, whereby the optical axis between a pair of the right and left optical systems of the binoculars can be easily adjusted.

Optical axis adjustable binoculars

A camera according to the present invention has an arrangement that a film is discharged to a side toward a subject after a picture has been taken, the instant camera comprising a grip portion formed on a right portion of a camera body when viewed in a normal photography state and from a position of a photographer operating the camera, an optical system disposed on a left portion of the camera body when viewed from the said position of the photographer and including at least a photographing lens, and a film cartridge loading portion which is capable of loading a film cartridge into a position between the grip portion of the camera body and the optical system in such a manner that an exposure surface of the film accommodated in the film cartridge faces the optical system.

Instant camera

An interpupillary distance adjusting mechanism for use in a binocular telescope, having a pair of lens-barrels which contain lens optical systems, respectively, and are placed in parallel with each other. The interpupillary distance adjusting mechanism further has first and second guide shafts, which slidably guide the pair of lens-barrels in a direction substantially perpendicular to the direction of the optical axes of the lens optical systems, interpupillary distance adjusting springs for pushing the pair of lens-barrels in a sliding direction, and an interpupillary distance adjusting cam which can adjust an interpupillary distance by sliding the pair of lens-barrels along the guide shafts as the result of undergoing a pushing force from the interpupillary distance adjusting spring, of converting a part of the pushing force in a direction which intersects the sliding direction, and of moving the pair of lens-barrels by pushing the pair of lens-barrels against the first guide.
