A driving apparatus which is capable of smoothly moving a follower by a cam portion, and realizes the stopper structure of the follower by a small number of components without the size increased. The driving apparatus comprises an up cam gear having an up radial cam and an up thrust cam, and a down cam gear unit having a down radial cam and a down thrust cam. The up cam gear and the down cam gear unit mesh with each other in a vicinity of a region in which a lift amount of the up radial cam with respect to the follower increases. In a vicinity of a position at which the up cam gear and the down cam gear unit mesh with each other, a lift amount of the up thrust cam is larger than a lift amount of the down thrust cam in the thrust direction.

In one aspect, the present invention is directed to a photo terminal stand system, comprising: a light-opaque case, in which a front facet thereof is a tempered one-way reflective mirror; a display, mounted behind the one-way mirror, such that a graphical presentation presented by the display is seen outside the case through the one-way mirror; a camera, mounted behind the one-way mirror, for taking a stills photo or a video sequence; an input device using an infrared touch overlay frame, for providing coordinates of the mirror on which a user touches; and a computer, configured to receive from the input device which a user touches the coordinates thereof and responsively generate the graphical presentation, and activate the camera to record an image or a video sequence, wherein the system is adapted to convert the coordinates of a point the user touches on the mirror to the coordinates of the display.

An eyepiece lens (EL) used for a viewfinder optical system (VF) for viewing, using the eyepiece lens (EL), an image formed by an objective lens (OL), an image displayed by a display member, or an object, wherein an antireflection coating (101) is disposed on at least one surface among the optical surfaces constituting the eyepiece lens (EL), and the antireflection coating (101) includes at least one layer (101g) formed by a wet process.

Provided is an imaging device that prevents glare resulting from light that leaks out from a subject display area of a display section in an OVF mode. A finder device can be switched between the OVF mode and an EVF mode. A subject display area and an information display area are set in an EVFLCD. In the OVF mode, nothing is displayed in the subject display area of the EVFLCD, and an information image is displayed in the information display area. An EVF shutter is set such that the light transmittance of a first area, which corresponds to the subject display area, becomes a low transmittance and the light transmittance of a second area, which corresponds to the information display area, becomes a high transmittance. The first area, which is set at low transmittance, blocks light that leaks from the subject display area.

A focusing plate having a light entrance side and a light exit side includes a Fresnel lens disposed on one of the light entrance side and the light exit side to form a condensing surface, and a plurality of microlenses disposed on the other one of the light entrance side and the light exit side to form a diffusion surface. The relation between the arrangement period of microlens units arranged on the diffusion surface and the interval between annular sections of the Fresnel lens satisfies predetermined mathematical conditions.

An apparatus is disclosed. The apparatus may include a housing detachably coupleable to an end of a sighting device. The housing may include a channel protruding from a side of the housing. The apparatus may include a one-way mirror disposed inside the housing. The one-way mirror may be positioned to allow an image from the sighting device to pass through the one-way mirror and reflect the image from the sighting device through the channel. The apparatus may include a mounting plate coupled to the housing. The mounting plate may include one or more adjustment bars that may be engageable with a visual recording device.

An image pickup apparatus capable of reducing unnecessary reflected light without narrowing an exposure area. A holding member holds a semi-transparent mirror and is rotatably supported by a mirror box so as to move between a mirror-down position in a photographing light path and a mirror-up position out of the photographing light path. A shading member is supported on an object-side end of the holding member via a rotation shaft so as to rotate between a closed position close to the holding member and an opened position apart from the holding member. An urging member energizes the shading member toward the opened position when the holding member is in the mirror-down position. An engagement portion engages with the shading member when the holding member rotates toward the mirror-up position so as to rotate the shading member toward the closed position against the urging force.
