Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an entrance child device with a camera, and more particularly to an entrance child device with a camera that can improve the image of a TV intercom device by reducing direct light incident on the camera of the entrance child device with a camera. .

  The conventional entrance slave unit with a camera has a rib for preventing infrared light irradiated at night from being reflected on the camera cover and preventing the reflected light from entering the camera.

Patent No. 2071025

However, in the case of a conventional entrance hall with a camera, sunlight may be incident on the camera depending on the installation environment and time zone of the entrance hall with a camera, and it may be difficult to check an image when calling or monitoring. was there.
In addition, the installation situation of the entrance unit with camera varies depending on the user, so it was not easy to take measures after installation.
This invention was made in order to eliminate the above-mentioned difficulty, and it aims at providing the entrance child machine with a camera which enabled it to reduce the sunlight which injects into a camera easily according to an installation condition. To do.

In order to achieve the above-mentioned object, an entrance cordless handset with a camera according to the present invention includes a call button for a visitor to call a resident, a camera for imaging the visitor, and a call unit for making a call with the resident. An entrance child device with a camera, which is fixed to a mounting base and is installed at the upper and left and right sides of the gap between the camera entrance door and the mounting base. A direct light avoidance plate that is approximately U-shaped and has a width larger than the width of the entrance unit with camera is fixed by press-fitting in some gaps so that the direct sunlight does not easily enter the camera. And
Further, it is characterized in that noise due to rain is absorbed by attaching rubber packing other than the portion sandwiched in the gap on the upper surface of the direct light avoidance plate.
Further, the direct light avoidance plate is provided with a slit for enabling adjustment of the length of the ridge protruding from the camera-equipped entrance slave when attached to the gap.
In addition, the direct light avoidance plate has at least one hole at a position sandwiched between the gaps, and the mounting base is provided with a protrusion that fits into the hole, thereby making it difficult to remove the direct light avoidance plate.

According to the door extension device with a camera of claim 1 of the present invention, the light avoidance plate can be directly attached by simply press-fitting into the gap between the camera entrance door and the mounting base. It is possible. Moreover, since the force which tries to open the right and left parts of the light avoidance plate directly is generated by sandwiching the substantially U shape, it cannot be easily removed.
According to the entrance unit with a camera of claim 2, since the rubber packing is affixed, the sound of rain can be absorbed, and the rain is directly avoided even when the visitor and the resident are talking. The sound hitting the plate is not picked up by the microphone of the entrance unit with camera, and a good call can be realized.
According to the entrance slave with a camera according to the third aspect, the length can be adjusted according to the installation environment, so that it is possible to cope with various situations.
According to the camera-equipped entrance slave device according to the fourth aspect, since the hole fits into the protrusion at the time of mounting, the fixing can be further strengthened.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, exemplary embodiments to which a camera-equipped entrance cordless handset of the invention is applied will be described with reference to the drawings.

FIG. 1 is a perspective view of a camera-equipped entrance slave according to an embodiment of the present invention, and is an exploded perspective view of FIG. As shown in FIGS. 1 and 2, the camera has a call button 11 for a visitor to call a resident, a microphone 12 for making a call with the resident, a speaker 13, and a camera 14 for capturing an image of the visitor. The entrance device 1, the mounting base 2 for attaching the entrance device with a camera and fixing it to the wall surface, etc., and the substantially U-shaped and the width of the camera so that the direct sunlight does not easily enter the camera 14. It is comprised from the direct light avoidance plate 3 larger than the width | variety of the attached subunit | mobile_unit 1, and the subunit | mobile_unit 1 with a camera is attached to the mounting stand 2 with the screw 4. FIG.
In addition, the mounting base 2 has a projection 21 for fitting a hole 33 of the direct light avoidance plate 3 described later (see FIG. 4). The direct light avoidance plate 3 has a plate portion 31 made of a plastic member and a raindrop. A rubber packing 32 that absorbs sound is attached and configured (see FIG. 3). Further, the direct light avoidance plate 3 has a slit 34 (see FIG. 5) for adjusting the length, and can be adjusted short by cutting according to the slit.

The assembly of the camera-equipped entrance child device will be described in detail below.
As shown in the cross-sectional view of the camera-equipped entrance child device 1 shown in FIG. 5, there are gaps T <b> 1 and T <b> 2 between the camera-equipped entrance child device 1 and the mounting base 2. Of these, the light avoidance plate 3 is directly press-fitted and fixed in the upper and left and right gaps T1. At this time, the direct light avoidance plate 3 is configured such that a rubber packing 32 is attached to a portion other than the portion of the upper surface sandwiched between the gaps, so that the direct light avoidance plate 3 is easily press-fitted into the gap T1.
Moreover, since the hole 33 of the direct light avoidance plate 3 fits into the protrusion 21 of the mounting base 2, it has a positioning effect and does not easily come off.
Thus, since the light avoidance plate 3 can be easily attached directly according to the installation environment, a clear image can be obtained.

Further, since the heel portion of the light avoidance plate 3 protrudes directly near the camera 11 and the microphone 12 of the entrance unit with camera 1, a good image can be obtained even on rainy days without water drops on the camera cover 141. It can be obtained, and it is difficult for rain to enter the microphone hole.
Further, since the camera cover 141 is less likely to have water droplets, the camera cover 141 is less likely to be cooled by rain, so that condensation of the camera cover 141 can be prevented.

It is a perspective view of the entrance child machine with a camera of the present invention. It is a disassembled perspective view of the entrance unit with a camera of this invention. It is a side view of the entrance child machine with a camera of the present invention. It is a perspective view of the mount of the entrance child machine with a camera of the present invention. It is a perspective view of the direct light avoidance plate of the entrance unit with a camera of the present invention. It is AA sectional drawing in FIG. 2 of the entrance child machine with a camera of this invention.
