Abstract:
Observation over a superwide field of view is possible with a short, lightweight, and inexpensive eyepiece optical system and a binocular barrel. A microscope optical system includes an objective optical system configured to collect light from a specimen; an imaging optical system configured to image the light coming from the specimen and collected by the objective optical system; and an eyepiece optical system configured to magnify the image of the specimen formed by the imaging optical system and form a virtual image in an eye of an observer, wherein the following conditional expressions are satisfied, M=Fntl/Fob×250/Fne (1) Fntl=Ftl×Kt (2) Fne=Fe×Kt (3) 0.4
Abstract:
An electronic image pickup apparatus according to the present invention includes a holding barrel, a lens frame supported by guide shafts inside the holding barrel and slidable and moveable in a direction of an optical axis, a light beam adjusting unit including an aperture and/or shutter for mechanically adjusting a light beam passing through the lens frame, and an image pickup element for converting an object image passed through the light beam adjusting unit to an electrical signal. The light beam adjusting unit comprises a base plate arranged perpendicular to the optical axis inside the lens barrel, an aperture member and/or a shutter member attached to the base plate, and an aperture driver for driving the aperture member and/or a shutter driver for driving the shutter member, arranged on the base plate.
Abstract:
A camera of the automatic aperture control type permits stop-down means which operates a diaphragm in cooperation with a shutter release operation first to move forward from a first position corresponding to the open aperture to a second position corresponding to a minimum aperture and then to move back from the second position toward the first position. The camera includes storage means for storing a position occupied by the stop-down means when the diaphragm assumes a proper aperture while the stop-down means moves from the first position to the second position so that the stop-down means is stopped at the stored position while the stop-down means moves back from the second position toward the first position.

Abstract:
An optical apparatus according to the present invention includes a cylindrical holding barrel, a plurality of moving lens frames which are held in the holding barrel such that the moving lens frames are moved back and forth in an optical axis direction, and a cam cylinder fitted on an outer surface of the holding barrel so as to move the moving lens frames. The cam cylinder slides and rotates on the outer surface of the holding barrel, and includes a first cam cylinder and a second cam cylinder each having a cam section on an inner surface thereof, and one end face of the first cam cylinder and one end face of the second cam cylinder are coupled to each other such that the first and second cam cylinders are rotated together.
Abstract:
An electronic image pickup apparatus comprises a shutter having a shielding member which can be inserted into or removed from an optical path of an optical system for forming an image of an object on a light receiving surface of an image pickup element, an inserting/removing mechanism for inserting or removing the shielding member into or from the optical path, a driver for driving the inserting/removing mechanism, and a manipulator for operating the inserting/removing mechanism by a driving system other than the driver.
Abstract:
A rectilinear barrel of a camera supporting a lens group in a manner that the lens group is movable along a rectilinear slot in the direction of its optical axis, a cam ring which has on its circumference a rib with a cutout portion and which rotates to drive the lens group in the direction of the optical axis, a threaded driving shaft for moving the rectilinear barrel between an imaging position and a retracted position, a zoom gear for rotating the cam ring when the rectilinear barrel is at the imaging position, and a locking tab for allowing the rectilinear barrel to move by means of the threaded driving shaft by aligning itself with the cutout portion and for locking the movement of the cam ring, and thus, the rectilinear barrel by aligning itself with the rib.
