Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intercom door subunit, and more particularly to an intercom subunit with an improved camera angle adjusting mechanism.

[0002]

2. Description of the Related Art As shown in FIG. 3 (a), a conventional doorphone handset uses a camera 40 having a wide image pickup range and capable of picking up a relatively wide range of subjects. Is captured, and the video of the visitor is confirmed on the monitor screen (not shown) on the base unit side. When this type of intercom sub-unit is installed at a gate post or entrance, the angle of the camera 40 is adjusted in advance so that the imaging position is optimal at the installation position.

This conventional intercom sub-unit is a camera 4
0 is fixed to the camera board 41, the board 41 is screwed to a plurality of frames described later, the frame is fixed to a housing (not shown), and a specific frame is slid to adjust the angle of the camera 40. I was adjusting. That is, the frame F1 and the frame 2 are movably fixed by the rivets in the holes F10 and F20. As shown in FIG. 3B, the frame F
5 has a long handle F52, which is sandwiched between a frame F3 and a frame F4, and a hole F3 is provided between the frames F3 and F5.
1 and the hole F51 are movably fixed by rivets, and the frames F3, F4, and F5 are movably fixed by rivets at the holes 30, 40, and 50. The hole 50 of the frame F5 has an oval hole shape in the direction of the elongated handle F52.

A camera board 41 to which a camera 40 is fixed
Is the hole F22 of the frame F2 and the hole F of the frame F3.
It is screwed at the position of 32 through the camera board mounting hole 42. Five frames F1, F2, F3, F4, F5 connected to each other by fixing the camera 40
Are screwed to the housing at positions of the holes F11 and F12 of the frame F1 and the holes F42 of the frame F4.

When the long handle F52 of the frame F5 is moved in its longitudinal direction, the long handle F52 of the frame F5 moves back and forth by the long diameter of the hole F50 in the shape of an oval hole, and the frame F5 with the holes F31, F51 and 30, and 50. The frame F3, which is movably fixed to, tries to move in the same direction. The frame F3 is movably fixed to the frame F4 through the holes F30 and F40, and the frame F4 is screwed to the housing through the hole F42. Therefore, the movement of the frame F3 parallel to the long handle F52 is prevented, but the frame F3 is prevented. F3 is hole F30 and hole F40
Performs a swinging motion around. That is, the hole F31 of the frame F3 swings around the holes F30 and F40 following the movement of the hole F51 of the frame F5.

Since the frame F3 is fixed to the camera board 41 and the camera board 41 is fixed to the frame F2, the swing of the frame F3 is caused by the hole F10 of the frame F1,
The swinging movement of the frame F2 around the hole F20 of the frame F2 is brought about. The camera 4 fixed to the camera substrate 41 by the swing motion of the frame F2 and the frame F3.
0 itself will also swing, and the doorphone entrance sub-unit will be installed at the gatepost or entrance, and the vertical handle F52 of the frame F5 will be moved back and forth so that the camera angle will be optimal at that installation position. I was adjusting.

[0007]

In the conventional intercom door subunit having the above structure, the number of parts for adjusting the vertical angle of the camera 40 is large, and it takes a lot of time to assemble the camera 40, which causes an increase in cost. There was a difficulty.

[0008]

An object of the present invention is to solve the above-mentioned conventional problems, and to provide an intercom door entrance device having an excellent camera angle adjusting mechanism while reducing the number of parts and reducing the cost. With the goal.

A locking recess is formed in the.

The operation of the intercom door subunit according to the present invention will be described below. This type of intercom doorphone has a camera to capture an image of a visitor, and a monitor screen (not shown) on the base unit side.
Check the video of the visitor. When this doorphone entrance slave is installed on the gatepost or entrance, the angle is adjusted in advance so that the camera angle is optimal in the imaging range of the installation position. Since the entrance cordless handset must be installed at a low position and only the lower part can be imaged, the camera must be turned upward beyond the normal range. If the locking projections 87 of the slide lid 7 are locked below the multiple locking recesses 85 of the back case 52 while the slide lid 7 covering the angle setting holes 5h of the back case 52 is floated, sliding occurs. The sliding protrusion T of the contact portion 71 also moves downward. At this time, the slit S of the flange arm 22 also tilts downward while moving the contact point with the sliding protrusion T. The lowering of the flange arm 22 including the slit S moves the lens flange 2, and the lens flange 2 swings within the bearing portion of the flange support portion 5b around the swing axis J.
Therefore, the lens 1 fitted to the lens flange 2 faces upward, and a desired camera angle can be obtained.

Alternatively, the angle setting hole 5h of the back case 52
Slide the slide lid 7 covering the
When the upper side of the plurality of locking concave portions 78 of the slide lid 7 is locked to the locking convex portion 58 of the back case 52, the slit S of the sliding contact portion 71 also moves downward. At this time, the sliding protrusion T of the flange arm 22 also tilts downward while moving the contact point with the slit S. The descent of the flange arm 22 including the slit S is
The lens flange 2 is moved, and the lens flange 2 swings around the swing axis J by pivotally supporting the swing axis J of the flange support portion 5b in the bearing portion thereof. Therefore, the lens 1 fitted to the lens flange 2 faces upward, and a desired camera angle can be obtained.

Further, the intercom door subunit according to the present invention is
It goes without saying that the vertical relationship is replaced with the horizontal relationship, and the horizontal relationship is replaced with the vertical relationship, which is suitable for the left-right adjustment of the camera angle in the entrance slave. As described above, the lens flange 2 into which the lens 1 is fitted is directly pivotally supported by the flange support portion 5b extending to the front case 51, and is slid on the sliding contact portion 71 of the slide lid 7 that covers the back case 52. Since they are in contact with each other, the angle of the camera can be easily adjusted by sliding the slide lid, and the number of parts used is small and the cost can be reduced.

[0026]

As is apparent from the above-described embodiments, the intercom door subunit according to the present invention uses a lens, a lens flange into which the lens is fitted, and a light which is fixed to the lens flange and passes through the lens. A doorphone handset unit in which a camera composed of a CCD board for converting into a signal is housed in a housing composed of a front case and a back case, and a camera cover is attached to the camera, which extends from the front case to the inside of the housing. Flange support that axially supports the lens flange, a slide lid that covers the angle setting hole provided in the back case for setting the camera angle, a flange arm that extends from the lens flange toward the back case, and a slide lid.
