摘要:
An optical-position adjusting device for an optical unit comprises a movement-conversion mechanism that converts a rotational movement of a rotary wheel cylinder into a linear movement of a lens barrel, and an optical-position adjusting mechanism that positions the lens barrel with respect to the rotary wheel cylinder. The optical-position adjusting mechanism has a ring and a fixing member. The ring is fit on the lens barrel in such a manner that the lens barrel can be moved along the central axis thereof. The ring is non-rotatable relative to the lens barrel. The fixing member is provided for fixing the ring to a frame in such a manner that the ring can be released from the frame.

A binocular incorporates a focusing and diopter correction mechanism having a common shaft, whereby the diopter adjustment is performed by rotation of the shaft and the focusing operation is performed by axial movement of the shaft. The lens-moving portions of the focusing/diopter adjustment mechanism are in a cavity having an access hole, in which the shaft enters the access hole through a water-tight seal to control the lens-moving portions of the adjustment mechanism. The binocular also incorporates a strap attaching mechanism having a spring-loaded clip and groove, wherein a flanged pin provided to a strap end is pushed past the clip into the groove, and the clip returns under the bias of the spring to hold the flanged pin in the groove. Also included is an eyecup adjustment mechanism having two positions defined by click-stops, wherein the eyecups are not rotatable, but are longitudinally slidable relative to corresponding support barrels.

A cleaning tool to remove foreign matter from a light receiving surface of an imaging device in a photographing device includes a body, a planar member, and a connecting member. The body extends in a longitudinal direction thereof. The planar member is provided at the end of the longitudinal direction, and has an adhesive surface to adhere to the foreign matter, a first edge, and a second edge that is at the opposite side of the first edge. The connecting member connects the body and the planar member, and the connecting member causes one of the first edge or the second edge of the planar member that is contact with the light receiving surface to detach from the light receiving surface earlier than the other, by an operation of the body, so that said foreign matter adheres to said adhesive surface.

A structure for assembly of a binocular telescope with a photographing function, comprises a lower frame, an upper frame, and an engaging mechanism. A pair of telescopic optical systems is mounted on the lower frame. A photographing unit is mounted on the upper frame. A first part of the engaging mechanism is provided on the lower frame. A second part of the engaging mechanism is provided on the upper frame. The first part and the second part are connected by assembling the upper frame onto the lower frame in such a manner that the photographing unit is placed between the pair of telescopic optical systems.

An zooming adjustment mechanism for an optical system is provided for reducing the length of the optical system along its optical axis, and enable the size down of the optical system. A cam ring is provided for adjusting distances between a first lens and a second lens that are constituting a telescope optical system in a binocular. Each of a first cam groove and a second cam groove includes two grooves. Two first cam grooves and two second cam grooves are formed on an outer circumferential surface at a distance along the circumferential direction. The two first cam grooves and the two second cam grooves are formed on the same area of the circumferential direction about the axis of the cam ring, i.e., the axis of a main shaft direction.

First lens frame has first front and rear shaft bearings that engage with the first guiding shaft along the optical axis, and a second shaft bearing that engages with a second guiding shaft along the optical axis. The first front and rear shaft bearings are spaced apart from each other along the first guiding shaft. Second lens frame has third front and rear shaft bearings that engage with the second guiding shaft, spaced apart form each other, and fourth shaft bearing that engages with the first guiding shaft. The third front and rear shaft bearings are arranged with the second shaft bearing between them, and fourth shaft bearing is disposed between the first front and second shaft bearings.

A binocular includes two telescope systems with parallel axes, eyepiece frames having a concave surface facing a user, adjustable eye cups with a secure locking mechanism, operation controls placed between the telescope systems, a focus adjustment mechanism, a diopter correction mechanism, and a magnifying-power-varying mechanism. The magnifying-power-varying mechanism includes rotatable cam rings and guide rings connected by a single connecting belt that moves perpendicular to the optical axes to rotate the cam rings. The connecting belt is supported and held in position so that it does not bind. The position of magnifying-power-varying lenses can be adjusted. The positions of the guide rings with respect to the telescope systems can also be adjusted.

A binocular includes two telescope systems with parallel axes, eyepiece frames, adjustable eye cups, operation controls positioned between the telescope systems, a focus adjustment mechanism, a diopter correction mechanism, and a magnifying-power-varying mechanism. The focus adjustment mechanism and diopter correction mechanism are arranged coaxially. The magnifying-power-varying mechanism includes rotatable cam rings and guide rings connected by a single connecting belt that moves perpendicular to the optical axes to rotate the cam rings. The connecting belt is supported and held in position so that it does not bind. The position of magnifying-power-varying lenses can be adjusted. During assembly, the magnifying-power-varying lenses can be mounted in the guide rings in a number of positions by rotating the lens frames holding the lenses about the optical axis and inserting sliders in linear guide grooves. Further, after assembly, the position of the magnifying-power-varying lenses along the optical axes in relation to the guide rings and cam rings can be adjusted.

A mounting plate has an opening provided for bonding a solid-state imaging device thereto. The opening of the mounting plate comprises a first edge portion and a second edge portion. The first edge portion corresponds to a first side of part of the contour of a light receiving area of the solid-state imaging device. The second edge portion corresponds to a second side of part of the contour. The first and second edge portions function as reference lines for positioning the solid-state imaging device over said opening.

An optical device includes an optical system mount plate, a casing, and a screw-hole forming part. An optical system is mounted on the optical system mount plate. The optical system mount plate is housed in the casing. The screw-hole forming part is provided on a bottom of the casing such that a screw provided on a tripod head can threadedly fit in the screw-hole forming part. The screw-hole forming part and at least one portion of the bottom are engaged with the optical system mount plate so as to counteract a rotational tightening force that is applied to the screw-hole forming part when the screw is threadedly tighten in the screw-hole forming part.
