Latest Patents

Sugihara's latest patents include a driving apparatus that drives a driven body using a lead screw and an image pickup apparatus equipped with this driving apparatus. The driving apparatus is designed to reduce degradation of driving performance and durability when a driven body is displaced using a lead screw. This lead screw features a lead groove formed over first and second members, with first and second surfaces facing each other in a width direction. The lead screw is rotated by a driving source, allowing a moving member to engage with the lead groove and move parallel to the lead screw according to its rotation. The driven body is displaced between first and second positions based on the movement of the moving member. Additionally, a first energization member energizes the moving member toward the second surface when it passes across a first junction at the boundary between the first and second members.

The image pickup apparatus, on the other hand, is capable of reducing unnecessary reflected light without narrowing the exposure area. It features a holding member that holds a semi-transparent mirror, which is rotatably supported by a mirror box. This allows the mirror to move between a mirror-down position in the photographing light path and a mirror-up position out of the path. A shading member is supported on the object-side end of the holding member and can rotate between a closed position close to the holding member and an opened position apart from it. An urging member energizes the shading member toward the opened position when the holding member is in the mirror-down position.
