Abstract: A vibration generation device capable of feeding back execution of image capturing to an image capturing person without affecting hand-shake correction control includes a vibration unit that generates vibration and a vibration control unit that performs vibration control on the vibration unit. In accordance with image capturing operation of an image capturing device, the vibration control unit causes the vibration unit to generate vibration at a second frequency band different from a first frequency band that the image capturing device has as a vibration range used for hand-shake correction control.

Abstract: [Problem] Image capturing is fed back to an image capturing person without affecting hand-shake correction control. [Solution] A vibration generation device capable of feeding back execution of image capturing to an image capturing person without affecting hand-shake correction control includes: a vibration unit configured to generate vibration; and a vibration control unit configured to perform vibration control on the vibration unit. In accordance with image capturing operation of an image capturing device, the vibration control unit causes the vibration unit to generate vibration at a second frequency band different from a first frequency band that the image capturing device has as a vibration range used for hand-shake correction control.

Abstract: An optical function device includes a base material layer, a semi-transparent layer formed on a principal plane of the base material layer, the semi-transparent layer reflecting light of incident light at a ratio determined in advance and passing remaining light; and a reflection prevention layer formed on a principal plane opposite to the principal plane of the base material layer with respect to the base material layer, the reflection prevention layer preventing reflection of the light passing through the base material layer. The image-capturing device includes an optical function device, a first light receiving device for receiving transmission light from the optical function device, and a second light receiving device for receiving reflection light from the optical function device.

Abstract: An image pickup device includes a fixedly provided half mirror that separates object light that has passed through a shooting optical system into transmitted light and reflected light, and an image pickup unit that generates an image of an object by receiving the transmitted light. The half mirror includes an optically transmissive film that is optically isotropic.

Abstract: Disclosed is an imaging apparatus that includes a table rotating device rotationally drives a disc-shaped recording medium; a pickup device capable of recording an information signal of an image corresponding to light from a subject; and an external case having a disc enclosure portion and the pickup device. The imaging apparatus further includes a disc cover rotatably attached to the external case; and a cover opening/closing mechanism capable of locking and unlocking the disc cover. In the imaging apparatus, the cover opening/closing mechanism includes a fixed claw integrally provided with the disc cover and a locking claw rotatably supported on one of the external case and a case-side member fixed to the external case, the fixed claw protruding in a direction substantially perpendicular to a main surface of the disc cover, and a convex portion protruding toward the disc cover provided at a front end of the fixed claw.

Abstract: A tape cassette comprising a flat, box-like cassette case, a recording medium tape accommodated in the cassette case, and a lid for covering and protecting, when the tape cassette is not in use, the recording medium tape at a portion exposed out of the cassette case, wherein a fulcrum of the lid is composed of a fulcrum pin and a receiving portion for receiving and holding the fulcrum pin, the receiving portion being made of an elastic synthetic resin and having a circular inner peripheral face for receiving the fulcrum pin, the inner peripheral face being partially notched for providing an introducing portion, anda frontage of the introducing portion being slightly smaller than an outer diameter of the fulcrum pin. This setup makes extremely easy the work for having the fulcrum pin be supported in the receiving portion.
