An imaging apparatus includes an apparatus main body including a lens mount to which a lens device is detachably attachable, and at least two protruding portions protruding further to a front side in a direction of an optical axis than a mount surface on which the lens mount is provided. Amounts of protrusion in the direction of the optical axis of the at least two protruding portions are approximately the same.

Imaging apparatus

An imaging apparatus includes a forced air cooling mechanism that uses driving of a fan. The imaging apparatus further includes a lens mount, an air intake port, and an air exhaust port. The lens mount is provided on a front surface of an apparatus main body. A lens device is detachably attachable to the lens mount. The air intake port is formed in a first protruding portion on a first side surface of the apparatus main body. The air exhaust port is formed in a second protruding portion on a second side surface of the apparatus main body. The second side surface is different from the first side surface.

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.

Image capturing apparatus that is reduced in size and has high operability, and operation member

An image capturing apparatus having a high operability irrespective of whether an accessory is attached to an apparatus body. The apparatus body includes a first connection section connected to the accessory, a first operation member disposed in a surface different from a surface where the first connection section is provided, and a second operation member disposed in the surface where the first connection section is provided. The accessory includes a second connection section which can be connected to the first connection section, and a third operation section disposed in a surface different from the surface where the second connection section is provided and is located in the vicinity of the second operation member in a state in which the accessory is attached to the apparatus body. The second operation member and the third operation member have at least one same function.

Image capturing apparatus having high operability

An image capturing apparatus having a forced air cooling function and capable of having an accessory attached thereto includes an image capturing apparatus body. A lens mount is provided on the apparatus body and can have a shooting lens removably attached thereto. An attachment portion is provided on the apparatus body and can have the accessory removably attached thereto. A built-in microphone is arranged on a side of a surface of the apparatus body, different from any of a surface where an air outlet port for discharging air used for forced cooling is arranged, a surface where the lens mount is arranged, and a surface where the attachment portion is arranged. The built-in microphone is arranged at a location closer to a top surface of the image capturing apparatus body than a bottom surface thereof.

Image capturing apparatus having built-in microphone

A main body of an image pickup apparatus which enables a user to easily interchange mount apparatuses, and at this time, adjust and finely adjust the flange back. At least one flange back adjustment member is removably held between the mount apparatus and an image pickup device holding member of the main body. In a state in which the mount apparatus is attached to the main body with at least one flange back adjustment member, on a projection surface in a case of viewing the main body from the front side in a direction of an optical axis, fixing portions that fix the mount apparatus to the main body, the at least one flange back adjustment member, and a connector of the main body or the mount apparatus are overlapped with an outside shape of the mount apparatus.

Main body of interchangeable-lens image pickup apparatus, mount apparatus for same, and flange back adjustment member

An electronic apparatus to which an accessory is removably attached. One of a grip and an image capture apparatus body includes a first attachment part formed by a first screw, a first electrical connection part disposed outside the first screw, and a first engagement part formed outside the first electrical connection part. The other of them includes a second attachment part formed by a second screw and screwed with the first screw, a second electrical connection part disposed outside the second screw, and electrically connected to the first electrical connection part, and a second engagement part formed outside the second electrical connection part, and engaged with the first engagement part. When the first and second screws are screwed, the first and second engagement parts are engaged, and the first and second electrical connection parts are electrically connected.

Electronic apparatus to which accessory is removably attached, accessory, and system

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.

Heat dissipation module and system camera including heat dissipation module

An image pickup apparatus with forced air-cooling structure, which is capable of improving heat radiating efficiency. The image pickup apparatus comprises a fan, an inlet, an outlet, and a duct, which has an inhaling part interconnecting with the inlet, a discharging part interconnecting with the outlet, and a cooling part connected to each of the inhaling part and the discharging part. Each of the inhaling part and the discharging part is connected to the cooling part in a direction intersecting with the cooling part.
