<Structure of front protrusion>
The upper protruding portion 1100 and the lower protruding portion 1101 provided on the front surface of the image pickup apparatus 1000 will be described with reference to FIGS. 1, 2, and 5 to 7. Figure 5 is a right side view of mounting the lens apparatus to the image pickup device 1000. Further, FIG. 6 is a top view of the image pickup apparatus 1000. Further, FIG. 7 is an enlarged view of the electrical contact 1043 in FIG.

For example, in addition to the upper protrusion 1100 and the lower protrusion 1101, the left protrusion extending from the left side of the image pickup device 1000 toward the front side in the optical axis direction and the left side protrusion portion extending from the right side of the image pickup device 100 toward the front side in the optical axis direction. An extending right side protrusion may be provided. In that case, the length of the upper protruding portion 1100 and the lower protruding portion 1101 in the X direction (left-right direction of the image pickup apparatus 1000) may be shorter than that of the present embodiment described above. Further, it is also possible to provide only the right side protrusion and the left side protrusion without providing the upper protrusion and the lower protrusion. Further, there may be a configuration in which two or more protrusions are provided among the upper protrusion, the lower protrusion, the left protrusion, and the right protrusion.

<Structure of side protrusion>
The detailed configuration of the left side cover protrusion 1031 and the right side cover protrusion 1016 will be described with reference to FIGS. 8 to 10. Figure 8 is a right side view of the imaging apparatus 1000. FIG. 9 is a cross-sectional view of the image pickup apparatus 1000, and is a cross-sectional view taken along the line AA in FIG. Further, FIG. 10 is a diagram showing a state in which the right side surface of the image pickup apparatus 1000 is placed on the lower side.

As shown in FIGS. 11 and 12, the left side cover 2030 of the image pickup apparatus 2000 has a left side cover projecting portion 2031 projecting from the left side cover first surface 2030a, which is a main surface, and a second left side cover projecting. It has a part 2033. A plurality of intake ports 2032 for sucking low-temperature air from the outside into the image pickup device 2000 by driving a fan 1404 (FIG. 4) arranged inside the image pickup device 2000 are formed in the left side cover protrusion 2031. There is.

The protrusion height H3 of the second left side cover protrusion 2033 is different from the protrusion height H1 of the left side cover protrusion 2031. The protrusion height H4 of the second right side cover protrusion 2019 is different from the protrusion height H2 of the right side cover protrusion 2016. In this embodiment, height H3 is less than the height H1, height H4 is smaller than the height H 2. The height H3 may be higher than the height H1, and the height H4 may be higher than the height H2.

As shown in FIG. 14, even when the image pickup device 2000 is placed on the ground with the right side facing down, the ridgeline of the right side cover protrusion 2016 and the ridgeline of the second right side cover protrusion 2019 are on the ground or the like. Contact. Further, even when the image pickup device 2000 is placed on the ground or the like with the left side surface facing downward, the ridgeline of the left side cover protrusion 2031 and the ridgeline of the second left side cover protrusion 2033 come into contact with the ground or the like. Therefore, since the intake port 2032 and the exhaust port 2017 are not blocked by coming into contact with the ground or the like, it is possible to prevent a failure due to an internal temperature rise due to a decrease in the heat exhaust efficiency of the image pickup apparatus 2000.
