Abstract: A small-sized image pickup apparatus which has space for locating a portion capable of applying image stabilization to an image pickup unit and is capable of capturing high-quality images by rapidly cooling an image sensor in the image pickup unit. The image pickup apparatus includes a housing, an image pickup unit disposed to divide an inner space of the housing into a first space and a second space, an electronic component, a first duct, and a second duct, where the second space is in front of the first space. The electronic component is in the first space. The first duct is in the first space, and includes a first heat exchanger that exchanges heat with the electronic component and a first flow path. The second duct is in the second space, and includes a second heat exchanger that exchanges heat with the image pickup unit, and a second flow path.

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.

Abstract: An image pickup apparatus that is capable of efficiently dissipating heat generated in a sensor substrate or a control substrate. An image sensor is implemented on the sensor substrate. A first heat dissipation section has four faces approximately parallel to an optical axis of an image pickup optical system of a lens unit and is fixed to the lens unit so that the four faces will surround the optical system from four sides. The control substrate is thermally coupled with the first heat dissipation section. A second heat dissipation section is arranged at a side opposite to the optical system in an optical axis direction with respect to the sensor substrate and is fixed to the first heat dissipation section. A heat conduction member is arranged between the sensor substrate and the second heat dissipation section in the optical axis direction so as to contact the both.

Abstract: An image capturing apparatus improved in heat dissipation efficiency while avoiding increase in size. A rotary fan is rotated to draw air from a suction port and discharge air from a discharge port. A heat dissipation duct includes an intake opening, a discharge opening, intake-side fins, an intake-side duct portion, and an exhaust-side duct portion. Projected shadows of at least part of the intake-side fins and at least part of the rotary fan overlap each other, as viewed from a direction of a rotational axis of the rotary fan. Ends of the intake-side fins toward the intake opening and the exhaust opening are closer thereto than ends of the rotary fan toward the same, respectively. The intake opening and the suction port of the rotary fan communicate with each other via a space adjacent to the end of the intake-side fins toward the discharge opening.

Abstract: A gripping device that enables a user to operate operation members like switches favorably. The gripping device is attached to an electronic apparatus and is used for gripping the electronic apparatus. The gripping device includes a gripping member of which a side surface is approximately circular, and an operation member that has an operation panel arranged along a circumference of the gripping member and that is operated for causing a predetermined action of the electronic apparatus. The operation member allows at least a first operation that presses the operation panel in a radial direction of the gripping member and a second operation that slides the operation panel in a circumferential direction of the gripping member from a position moved by the first operation.

Abstract: A heat dissipation module suitable for a system camera formed by a plurality of modules. A heat dissipation module has a first engagement structure which is provided on a first surface and with which a first mating module is removably engaged and a second engagement structure is provided on a second surface parallel to the first surface and with which a second mating module is removably engaged. A first heat reception portion is configured to receive heat from the first mating module. The heat dissipation module also has a first interface electrically connected to the first mating module, and a second interface electrically connected to the first interface and electrically connected to the second mating module. A fan unit is provided between the first surface and the second surface, for dissipating heat received by the first heat reception portion to the outside.
