TECHNICAL FIELD OF THE INVENTION
The present invention relates to a camera-equipped intercom provided with a camera whose imaging angle can be adjusted, which can be easily assembled, disassembled, and adjusted.
[0002]
[Prior art]
2. Description of the Related Art A camera-equipped intercom capable of adjusting an imaging angle of a camera has been conventionally proposed.
FIG. 8A is a partially cutaway cross-sectional view showing an example of such a conventional camera-equipped intercom, and FIG. 8B is a cross-sectional view of the camera-equipped intercom shown in FIG. is there.
[0003]
8A and 8B, 101 is an intercom with a camera, 102 is a base, 103 is a front cover detachably attached to the base 102, 104 is a camera, and 105 is a camera 104 and an irradiation lamp 106. Reference numeral 107 denotes a printed circuit board on which the camera unit 105 is mounted, 108 denotes a movable arm attached to the left and right ends of the printed circuit board 105, and 109 denotes a holder on which the movable arm 108 is rotatably attached via a horizontal shaft 110. Reference numerals 111 and 112 denote washers, 113 denotes spacers, and 114 and 115 denote fixing tacks.
[0004]
One of the movable arms 108 (the left side in FIG. 8B) has an operation lever 116 extending downward and a projection 118 for locking a spring 117 projecting upward. A nut member 121 is provided on the operation lever 116, and by rotating the adjusting screw 119, the nut member 121 moves in the direction of B ← → C. The structure is such that it rotates substantially in the direction of B ← → C.
[0005]
Therefore, the operator rotates the adjusting screw 119 using a screwdriver and moves the nut member 121 in the direction of arrow B ← → C, thereby tilting the camera unit 105 up and down about the horizontal axis 110. The imaging angle can be adjusted.
[0006]
[Problems to be solved by the invention]
However, in the above-described conventional intercom with a camera, as shown in FIG. 8A, the camera unit is held by a holding member provided on the base side, and the operator can adjust the adjustment screw provided on the front cover side. By rotating the camera unit, the camera unit is tilted up and down about the horizontal axis to adjust the imaging angle, so that the structure of the apparatus is complicated and the cost is high.
[0007]
In addition, since the operating lever provided on the base side and the adjusting screw provided on the front cover side are screw-fitted, the screw fitting between the nut member and the adjusting screw is released to separate the base and the front cover. However, it is difficult and troublesome to assemble or disassemble the apparatus, and once the screw fitting is removed, there is a problem that the imaging angle needs to be adjusted again with the adjusting screw.
[0008]
SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has a camera with a simplified structure of an apparatus, cost reduction, no need for readjustment of an imaging angle, and easy assembly and disassembly. It is intended to provide intercoms.

The operation unit 11 has operation grooves 11A, 11B, and 11C into which the ends of the lever 10 of the camera unit 5 are fitted. When the operation unit 11 is slid in the direction of the arrow, the operation grooves 11A to 11C are formed. The end of the lever 10 moves up and down in a state where the lever 10 is continuously fitted.
[0019]
FIGS. 6A and 6B are diagrams schematically showing an assembling relationship of a front cover, a camera unit, an operation unit, and a base, wherein FIG. 6A is a partial longitudinal sectional view, and FIG. In the figure, the components described so far are denoted by the same reference numerals and description thereof is omitted.
When the front cover 3 is mounted on the base 2 on which the operation unit 11 is slid in the direction of the arrow in the figure, the lever 10 of the camera unit 5 supported by the front cover 3 is operated. 11B, 11C). When the front cover 3 is removed, the fitting of the lever 10 and the operation grooves 11A (11B, 11C) can be easily removed. Moreover, as already described with reference to FIG. 4, the camera unit 5 maintains the inclination angle even when the front cover 3 and the base 2 are separated.
[0020]
In this way, in the intercom with camera of the present invention, even if the front cover and the base are separated for repair or the like, the imaging angle of the camera is maintained, so that when the camera is reassembled, the angle of the angle is reduced. No need to readjust.
FIGS. 7A and 7B are diagrams illustrating an example of a method of adjusting the imaging angle of the camera in the camera-equipped intercom of the present invention. FIG. 7A is a partial vertical cross-sectional view illustrating a state when the camera unit is turned upward, and FIG. ) Is a partial schematic diagram of the position of the operation unit at that time as viewed from the back side of the apparatus, (c) is a partial vertical cross-sectional view showing a state where the camera unit is horizontal, and (d) is a position of the operation unit at that time. It is the partial schematic diagram seen from the back side of the apparatus. In the figure, the components described so far are denoted by the same reference numerals and description thereof is omitted.
[0021]
As shown in FIGS. 7A and 7B, when the operation unit 11 is slid to the left as viewed from the back side of the camera-equipped intercom 1, the end of the lever 10 is fitted into the operation groove 11A of the operation unit 11.
