Abstract

PURPOSE:To easily clean a transparent body by covering a lens section with a freely attachable and detachable lens cover provided with the transparent body so as to eliminate the need for a large sized camera case containing the camera main body and the lens section. CONSTITUTION:A mount 11a of a lens cover 11 fitted to a camera main body 3 to cover the surrounding of a lens section 4 to the camera main body 3 is formed detachably without a gap by a method such as a snap fit. A mount 12a of a transparent plate 12 being a transparent body fitted to the lens cover 11 opposite to the lens to the lens cover 11 is formed to be, e.g. screw fit and removable by a double-side tape or an adhesive tape or the like. Since dirt of the lens is prevented by using the lens cover 11 covering only the surrounding of the lens section 4, a large sized camera cover used for a conventional camera is not required. Thus, the camera is easily installed in a space smaller than that for a conventional device and the cleaning or replacement of the transparent plate 12 is facilitated.

[0016]

Embodiments of the present invention will be described below with reference to the drawings. Example 1. 1 is a configuration diagram showing a surveillance camera apparatus according to Embodiment 1 of the present invention. The same or corresponding parts as in FIG.

In the figure, reference numeral 11 denotes a lens cover attached to the camera body 3 so as to cover the periphery of the lens portion 4. The attachment portion 11a of the lens cover 11 to the camera body 3 is formed by, for example, snap fitting or the like. It is removable and has no gaps. Reference numeral 12 denotes a transparent plate as a light-transmitting body, which is attached to the lens cover 11 so as to face the lens. An attaching portion 12a of the transparent plate 12 to the lens cover 11 is, for example, screwed,
It is removable with double-sided tape or adhesive tape.

In such a surveillance camera device, the lens cover 11 covering only the periphery of the lens portion 4 is used to prevent the lens from being soiled, so that the conventional large-sized camera cover 1 is unnecessary, Therefore, it can be easily installed in a smaller space than before. Also, by removing only the lens cover 11 or the transparent plate 12,
The transparent plate 12 can be easily cleaned and replaced.

Example 2. Next, FIG. 2 is a block diagram showing a surveillance camera device according to a second embodiment of the present invention. In the first embodiment, the lens cover 1 attached to the camera body 3
However, as shown in the second embodiment, the mounting portion 13
The lens cover 13 attached to the lens unit 4 by a
May be used, and the same effect as that of the first embodiment can be obtained.

Example 3. 3 is a block diagram showing a surveillance camera apparatus according to Embodiment 3 of the present invention. In the figure, 14 is a lens cover that is detachably attached to the camera body 3, 15 is two lenses that are attached inside the lens cover 14, and 16 is a lens cover that is detachable from the lens cover 14 so as to face the lens 15. It is a transparent plate as an attached translucent body.

With this structure, the same effect as that of the first embodiment can be obtained, and the structure can be simplified by omitting the lens portion 4.

Example 4. Further, FIG. 4 is a block diagram showing a surveillance camera apparatus according to Embodiment 4 of the present invention. In the figure, 17 is a transparent cap as a cap-shaped light-transmitting body, which is detachably attached to the tip of the lens unit 4.

By using such a transparent cap 17, it is possible to further reduce the size of the device while preventing the lens from being soiled, and to easily clean or replace the transparent cap 17.

Example 5. Next, FIG. 5 is a configuration diagram showing a surveillance camera device according to a fifth embodiment of the present invention. In the figure, reference numeral 18 is a transparent film as a film-shaped translucent body, which is detachably attached to the surface of the lens 15 in the lens portion 4.

In such a surveillance camera device, since the lens 15 is prevented from being soiled only by the transparent film 18, the entire device can be further downsized. Further, the transparent film 18 can be easily cleaned or replaced by peeling it from the lens 15.

In each of the above-mentioned embodiments, the transparent plates 12 and 16, the transparent cap 17 and the transparent film 18 are used as the translucent body.
However, the material is not limited to a transparent material, and may be a colored material or a semi-transparent material as long as it has a light-transmitting property that can maintain the performance of the device.

Further, in the above-mentioned Embodiments 1 and 2, the lens covers 11 and 13 and the transparent plate 12 are shown as separate bodies, but if the lens covers 11 and 13 are detachable, they are transparent. The plate 12 may be provided integrally with the lens covers 11 and 13.

As described above, in the surveillance camera apparatus according to the first aspect of the present invention, the lens cover that covers the periphery of the lens portion is detachably attached to at least one of the camera body and the lens portion, and the lens cover is attached to the lens. Since the opposite translucent body is provided on the lens cover, a large camera case for housing the camera body and lens part is not required, the installation space can be reduced, and the translucent body can be easily cleaned. It is possible to achieve such an advantage that maintenance can be facilitated.

In the surveillance camera apparatus according to the second aspect of the present invention, a lens cover that covers the periphery of the lens portion is attached to at least one of the camera body and the lens portion, and the translucent body facing the lens is used as the lens cover. Since it is detachably attached, in addition to the same effect as the invention of claim 1, the effect of facilitating the cleaning and replacement of the translucent body is exerted.

Further, in the surveillance camera apparatus according to the invention of claim 3, the lens cover is detachably attached to the camera body,
Since the lens is mounted in the lens cover and the translucent body facing the lens is removably mounted on the lens cover, in addition to the same effect as the invention of claim 2, the structure of the device can be simplified. It has the effect of being able to.

Furthermore, in the surveillance camera device of the invention of claim 4, since the cap-shaped light-transmitting body facing the lens is detachably attached to the lens portion, in addition to the same effect as the invention of claim 2, Since the lens cover is not used, the device can be made more compact.

Further, in the surveillance camera apparatus of the fifth aspect of the invention, since the film-shaped light-transmitting body is detachably attached to the surface of the lens, in addition to the same effect as the invention of the fourth aspect. Thus, there is an effect that the device configuration can be further simplified.
