Description

  The present invention relates to an imaging control apparatus that converts an imaging signal supplied from a camera unit into a video signal.

In a camera for business use, in particular, a camera for use in a broadcasting station and a VTR unit integrated with a VTR unit, a ventilation hole is formed in the casing and heated by a power supply circuit or the like provided therein. Air is allowed to escape outside the housing through the ventilation holes.
However, when such a camera is used in an environment where water droplets are splashed, such as rainy weather or a poolside, the water droplets may enter the inside of the housing through the ventilation holes and cause damage to internal electrical components.
In order to avoid such inconvenience, a camera in which a cover made of a shape memory alloy is attached to the ventilation hole has been proposed (see Patent Document 1).
In this camera, when the temperature inside the case rises, the cover is bent and the vent hole is opened to let the air heated inside the case escape to the outside through the vent hole. When the temperature inside the casing does not rise, the cover closes the vent hole to prevent water droplets from entering.

The exhaust fan 106 guides the outside air through the ventilation path 56, the space S, and the ventilation hole 42 to the inside of the housing 30, so that the noise of the exhaust fan 106 is transmitted through the ventilation path 56, the space S, and the ventilation hole 42. It is discharged to the outside above the body 30, thereby preventing it from being transmitted to the ear of the user who is using the imaging control device 20 on the shoulder.

Next, the function and effect of this embodiment will be described.
As shown in FIGS. 5 and 7, the cover 50 is attached to the upper wall 40 of the housing 30 by the bolt 51 being screwed into the female screw 4802 of the boss 48 for mounting the cover via the bolt mounting seat 5212. Worn.
As shown in FIG. 16, in the state where the cover 50 is attached to the upper wall 40, a ventilation path 56 is provided at a location of the cover 50 excluding the portion of the main body wall 52 facing the ventilation hole 42, and the ventilation path 56 is formed in a bent shape so that the upper wall 40 of the housing 30 is not exposed to the outside of the cover 50.
Therefore, when the image pickup control device 20 is used in an environment such as rain, and a water drop falls on the outer surface of the cover 50 from above, the water drop once hits the bent air passage 56 and the momentum is reduced. It is dropped onto the upper wall 40 through the ventilation path 56 and guided onto the upper wall 40. The water accumulated on the upper wall 40 is discharged from the drain hole 59 of the cover 50 to the outside of the cover 50.
At this time, since the momentum of the water droplets dropped on the upper wall 40 is weakened, it is possible to prevent the splashes of the water droplets hitting the upper wall 40 from entering the ventilation hole 42 and air flowing through the ventilation path 56. Therefore, it is advantageous to efficiently release the air whose temperature in the housing 30 has risen to the outside of the housing 30 while reliably preventing water from entering.
Further, in the present embodiment, a water droplet splash preventing wall portion 58 that protrudes toward the upper wall 40 is provided at an inner surface 4002 portion of the main body wall 52 located between the ventilation hole 42 and the ventilation path 56. Therefore, it is possible to more reliably prevent the splash of water droplets dropped on the upper wall 40 from entering the ventilation hole 42.

In addition, a structure that prevents water droplets from entering the ventilation hole 42 by interposing a water-absorbing member such as a sponge through which air can flow between the cover 50 and the upper wall 40 including the ventilation hole 42 is also possible. Conceivable. In this case, there is a limit to the amount of water that can be absorbed by the water-absorbing member, and the cost of the water-absorbing member is excessive. However, in this embodiment, such a water-absorbing member is not necessary and the inconvenience described above. There is no.

Further, in the present embodiment, the ventilation hole 42 provided in the upper wall 40 is circular, and the cylindrical upright wall 44 projects from the upper wall 40 so as to surround the ventilation hole 42. 20, when the housing 30 is tilted in the left-right direction from the horizontal state, the water accumulated on the upper surface of the upper wall 40 moves around the cylindrical outer peripheral surface of the upright wall 44 as shown by arrows in the figure. Since the water is smoothly moved along the direction and discharged from the drain hole 59 to the outside of the cover 50, the water accumulated on the upper surface of the upper wall 40 gets over the upright wall 44 and enters the ventilation hole 42. It is advantageous in preventing.
On the other hand, when the ventilation hole 42 has a rectangular shape, and the upright wall 44 having a rectangular frame shape is formed on the upper wall 40 so as to surround the four sides of the ventilation hole 42, the housing 30 is left and right. When inclined in the direction, the water accumulated on the upper surface of the upper wall 40 tends to stagnate on the outer surface of the standing wall 44, and there is a concern that the stagnant water may climb over the standing wall 44 and enter the ventilation hole 42. In this embodiment, such inconvenience can be surely prevented.
Further, in the present embodiment, when the exhaust fan 106 does not operate, the air heated by the power source 104 in the housing 30 moves upward and smoothly passes through the ventilation holes 42, the space S, and the ventilation path 56. Run away to the outside.
On the other hand, when the exhaust fan 106 is operated, an air flow is formed in which outside air flows into the housing 30 through the ventilation path 56, the space S, and the ventilation holes 42. 56 is formed in a bent shape so that the upper wall 40 of the housing 30 is not exposed to the outside of the cover 50, and a water droplet splash preventing wall portion 58 is located between the ventilation hole 42 and the ventilation path 56. Therefore, it is possible to reliably prevent the splash of water droplets from entering the ventilation hole 42.
