る。Next, the operation of the monitoring camera device will be described. For example, in a situation where the monitoring camera device is installed in an outdoor environment, the camera device 6 in the camera case 1
However, for example, the state of rivers and traffic is constantly photographed through the defroster glass 3 and the image is transmitted to a remote monitoring monitor (not shown). The defroster temperature sensor 7 is set so that energization is turned on at 20 degrees Celsius or less (hereinafter, celsius is omitted) and energization is turned off at 30 degrees or more. This prevents fogging of the defroster glass 3 due to various changes.

やすい。As described above, the defroster 3a is set so that the power is turned on when the temperature of the defroster temperature sensor 7 is 20 degrees or less, and the power is turned off when the temperature of the temperature sensor 30 is 30 degrees or more. However, the calorific value is small due to its configuration. On the other hand, when the front panel 2 and the defroster glass 3 are blown with snow, especially during winter snowfall, the heat generated from the defroster 3 is deprived, and the temperatures of the front panel 2 and the defroster glass 3 tend to be 0 ° C. or lower.

ａ近傍に堆積する氷雪である。However, since the defroster 3a generates heat as described above, the snow on the surface of the defroster glass 3 melts and falls as water droplets. Further, the water droplets that have fallen downward accumulate in the step portion 4a, and freeze again when the front panel 2 is at 0 degrees or less. That is, if this operation is repeated, ice and snow will accumulate in places where the heat from the defroster 3a of the step portion 4a does not reach. 6 is a front view of the monitoring camera device shown in FIG. 4 when ice and snow accumulate on the stepped portion 4a. FIG. 7 is a side sectional view of FIG.
This is ice and snow that accumulates near a.

As a result, ice and snow 9 may enter the visual field range 8 of the camera device 6, which may hinder the photographing of the camera device 6. In FIGS. 6 and 7, the lower step portion 4a is mainly used.
Is shown, but depending on the direction of the wind and snow, the ice and snow 9 may also be deposited on the side and / or the upper step portion 4a, causing the same trouble.

一以下としてデフロスタガラス３ｂを押えている。In FIGS. 1 to 3, projections 2c are provided on the upper and lower portions of the front panel 2a to support the defroster glass 3b. In addition, the height of the protruding portion 2c and the height of the defroster glass 3b are made equal to or less than each other, thereby eliminating a vertical step such as the step portion 4a shown in FIG. Further, the height of the glass holder 10 supporting the defroster glass 3b from the side is set to be equal to or less than the height of the defroster glass 3b. Further, the inclined portion 3c has a negative gradient toward the front surface side of the front panel 2a, and the inclined portion 10a has a positive gradient corresponding to the inclined portion 3c. As a result, the glass presser 10 is moved to the inclined portions 3c and 10a.
The defroster glass 3b is held down by setting the surface height equal to or lower than that of the defroster glass 3b.

Next, the defroster glass 3b is arranged between the protruding portions 2c of the front panel 2a and pressed against the packing 4a. This prevents the packing 4a from falling down when the defroster glass 3b is removed from the front panel 2a. Next, the defroster glass 3b is inclined by the glass retainer 10 to the inclined portion 3c.
And 10a. Next, the glass presser 10 is attached to the front panel 2a with screws or double-sided tape.

Ice and snow 9 as shown in FIG. 7 will not be deposited on the front panel 2a. As a result, the ice and snow 9 do not enter the visual field range 8 of the camera device 6, and the trouble of shooting by the camera device 6 is solved. In this embodiment, the protruding portion 2c is arranged in the up-down direction and the glass presser 10 is arranged on the side.
As long as the defroster glass 3b can be held, it goes without saying that the arrangement and direction of the projection 2c and the glass presser 10 may be freely changed.
