Abstract: In an imaging apparatus system, a first imaging apparatus includes a first front casing, a common rear casing, a first lens mount attached to the first front casing, and a common monitor attached to the common rear casing. A second imaging apparatus includes a second front casing, a common rear casing, a second lens mount attached to the second front casing and different from the first lens mount, and a common monitor. When the first and second front casings are respectively attached to the common rear casings and, the center of the first lens mount and the center of the second lens mount are identical, regarding the relative positions in the left-right direction with respect to the common rear casings and.

Abstract: An imaging apparatus system includes a first imaging apparatus, and a second imaging apparatus. The first imaging apparatus includes a first top casing including a casing top surface, and a common rear casing including a casing rear surface. The second imaging apparatus includes a second top casing including a casing top surface, and the common rear casing. The first top casing has a shape in which a vent hole is formed in the second top casing.

Abstract: An imaging apparatus includes a casing having an inlet port and an exhaust port, at least one heat source that is disposed in the casing and includes at least an image sensor, a fan that is disposed in the casing, takes in outside air through an inlet port, and blows out the taken-in outside air toward the exhaust port, and a display panel unit that includes a display panel and is rotatably provided on a rear surface of the casing. The inlet port includes first and second inlet ports that open in different directions. When viewed in a facing direction between the display panel unit in a housed state and the casing, the entire second inlet port is provided in a portion of the casing covered by the display panel unit in the housed state.
