  • Publication number: 20230421882
    Abstract: An image pickup apparatus in which a cable is prevented from coming off a connecting terminal without requiring complicated operations. The image pickup apparatus comprising an image pickup apparatus main body, the connecting terminal provided in the image pickup apparatus main body and to which the cable is electrically connected, a grip belt that assists a user in holding the image pickup apparatus main body, and a cable clamp attachable to and detachable from the grip belt, wherein the cable clamp comprises a first holding portion that includes a U-shaped portion opened in a U shape and holds the grip belt and a second holding portion that includes a U-shaped portion opened in a U shape and holds the cable, and wherein the U-shaped portion of the first holding portion and the U-shaped portion of the second holding portion are opened in different directions.

  • Publication number: 20230353850
    Abstract: An image capturing apparatus includes an image sensor unit including an image sensor board on which an image sensor is mounted, a first drive mechanism that drives the image sensor unit in a first direction orthogonal to an optical axis of the image sensor, a second drive mechanism that drives the unit in a second direction orthogonal to the optical axis and different from the first direction, and a first duct disposed on an opposite side of the board to a surface on which the sensor is mounted, in a state opposed to the board, to allow cooling air to pass therethrough. The first duct has an air suction port and an air discharge port. When viewed from the optical axis direction, the first drive mechanism, the second drive mechanism, the air suction port, and the air discharge port do not overlap around the image sensor.

  • Patent number: 11800208
    Abstract: An image sensor converts an optical image formed by an imaging optical system to video signals. A heat dissipation section discharges heat generated in an image sensor to the outside. The imaging optical system, the image sensor, the heat dissipation section, and a battery chamber are arranged on an extension line of an axis of the system in the mentioned order. The battery chamber has an upper surface tilted forward in a direction in which the image sensor is disposed with respect to the axis by a predetermined angle. A projected shadow of a portion, close to the heat dissipation section, of an upper end portion of the battery chamber, which is projected from an upper surface side of the image capturing apparatus, overlaps the heat dissipation section.
