FIG. 4 is a view schematically showing still another embodiment of the cover body, and FIG. 4A is a sectional view schematically showing a preferred shape of the cover body 4. 4 (b)
FIG. 4 is a cross-sectional view schematically showing a less preferable shape of the cover body 4.

Referring to FIG. 4 (a) and FIG. 1, the cover body 4 is provided on the inner surface side Sr of the corner portion which transitions from the front surface S2a of the main body 2 to the upper side surface S2b.
b has a gentle curved surface Rb for preventing a line pattern from being formed in an image captured by the camera 3.

The curved surface Rb is formed so as to have a substantially concentric relationship with a curved surface Ra formed on the outer surface side Sra of the corner portion which transitions from the front surface S2a of the main body 2 to the upper side surface S2b. ing.

The cover body 4 prevents a line pattern from being formed in the image picked up by the camera 3 on the inner surface side Srb of the corner portion which transitions from the front face S2a of the main unit body case 2 to the upper side face S2b. As a result, the problem that occurs in the cover 4A shown in FIG. 4B does not occur.

First, the problem occurring in the cover 4A shown in FIG. 4B will be described in detail.

In the cover body 4A shown in FIG. 4B, the cover body 4 has a curved surface having a large curvature at a corner portion where the front surface S2a of the main unit body case 2 transitions to the upper side surface S2b, and at the inner surface side Srb. Rc is formed.

In the case where a curved surface Rc having a large curvature is formed on the inner surface side Srb of the corner portion that transitions from the front surface S2a of the main unit body case 2 to the upper side surface S2b thereof as in the cover body 4A, Light emitted from the light emitting element 7 and passing through one side Rc1 of the curved surface Rc;
The light passing through the other side Rc2 of c is directed in significantly different directions from each other at this corner.

Due to the above, when light is emitted from the light emitting element 7, the light emitting element 7 is provided outside the corner portion of the cover body 4A, which transitions from the front face S2a of the main body 2 to the upper side face S2b. There is a problem that a portion where the light irradiated from 7 does not reach is formed, and when the light emitting element 7 is turned on to illuminate the subject (such as a visitor), a linear shadow is formed on the subject (such as a visitor). Occurs.

As a result, when the light emitting element 7 is turned on and an image of a subject (a visitor or the like) is captured by the camera 3, when the image captured by the camera 3 is viewed on a monitor television (not shown), the image is displayed. Inside, dark lines are formed.

The light entering one side Rc1 of the curved surface Rc and the light entering the other side Rc2 of the curved surface Rc are directed in different directions.

In the cover 4A shown in FIG. 4 (b), the thickness of the corner portion of the cover 4A which shifts from the front face S2a of the slave body case 2 to the upper side surface S2b of the slave body case 2 is large. A part and a thin part are formed.

Due to the above, when an object (a visitor or the like) is imaged by the camera 3, one side R of the curved surface Rc
The light entering c1 and the light entering the other side Rc2 of the curved surface Rc are directed in different directions from each other. As a result, the image captured by the camera 3 is displayed on the front side of the main body case 2 of the cover body 4A. Distortion occurs in a portion imaged through a corner portion that shifts from S2a to the upper surface S2b,
When this image is viewed on a monitor television (not shown), a line pattern does not appear, causing a problem that the visitor's face or the like is crushed.

On the other hand, the cover 4 shown in FIG.
Then, from the front surface S2a of the main unit 2 to the upper surface S2a.
The camera 3 is located on the inner surface side Srb of the corner portion which shifts to 2b.
Has a gently curved surface Rb for preventing a line pattern from being formed in an image to be captured. For this reason, the light radiated from the light emitting element 7 causes the cover body 4 to be uniformly bent in the radiation direction at the corner part where the cover body 4 transitions from the front face S2a to the upper side face S2b of the main body body case 2, resulting in the cover body 4. In the outer part of the corner part which transitions from the front face S2a to the upper side face S2b of the main unit body 2 of No. 4, a portion where the light emitted from the light emitting element 7 does not reach is not formed. When light is emitted to illuminate a subject (a visitor or the like), a linear shadow is not formed on the subject (a visitor or the like).

As a result, when the light emitting element 7 is turned on and an image of a subject (a visitor or the like) is captured by the camera 3, when the video captured by the camera 3 is viewed on a monitor television (not shown), the video is displayed. No dark line is formed therein, and the subject (a visitor or the like) is clearly displayed on a monitor television (not shown).

The light entering from the curved surface Rb is transmitted from the front surface S2a of the slave body case 2 of the cover body 4 to the upper surface S2a.
In the corner part which shifts to 2b, it is evenly bent.

Further, in the cover 4 shown in FIG.
The corners of the cover body 4 that transition from the front face S2a of the slave body case 2 to the upper side surface S2b of the slave body case 2 are formed to have the same or substantially the same thickness.

As a result, a subject (a visitor or the like) is
When the image is taken by the camera 3, almost no distortion occurs in the image taken by the camera 3 through the corner portion that transitions from the front surface S <b> 2 a of the main body 2 of the cover body 4 to the upper side surface S <b> 2 b. Therefore, when this image is viewed on a monitor television (not shown), no line pattern appears, the face of the visitor does not collapse, and the subject (the visitor, etc.) is clearly displayed on the monitor television. (Not shown).

FIG. 5 is a cross-sectional view schematically showing the inside of a camera-equipped door phone slave unit.

In FIG. 5, a member denoted by 8 is a control device (CP) for controlling the camera 3 and the intercom slave unit 1 with the camera.
U) (not shown) and the like, a member indicated by 9 detects an energizing lamp for illuminating the call button 5, and a member device indicated by 10 detects the brightness of the subject and its surroundings. Light sensors (brightness sensors) are shown, respectively.

The light-emitting element 7 is provided to illuminate a subject (a visitor or the like) picked up by the camera 3 when the night is around and the surroundings of the doorphone slave unit 1 with a camera are dark.

Further, an optical sensor (brightness sensor) 10
Is for detecting the brightness around the doorphone slave device 1 with a camera.

Then, an optical sensor (brightness sensor) 1
Information D10 detected by 0 is sent to a control device (CPU) (not shown). The control device (CPU) (not shown) transmits information D10 detected by the optical sensor (brightness sensor) 10 to a threshold value Dth stored in advance in the control device (CPU) (not shown). Compare. Then, the control device (CPU) (not shown) determines that the information D10 detected by the optical sensor (brightness sensor) 10 is darker than the threshold value Dth (D10 <Dt).
h), the light emitting element 7 is turned on for a predetermined time, and it is determined that the information D10 detected by the optical sensor (brightness sensor) 10 is brighter than the threshold value Dth (D10 ≧ Dt).
In h), the light emitting element 7 is controlled so as not to be turned on.

The circuit board 8 is rotatably provided, so that the angle of the camera 3 can be changed by changing the angle of the circuit board 8.

Next, a preferred combination of the light emitting element 7 and the camera 3 will be described.

It is preferable to use, for example, an infrared light emitting diode as the light emitting element 7 and to use an infrared camera as the camera 3.

In this case, the smoke portion 4a of the cover 4
Is made of a material that transmits infrared rays.

As described above, when an infrared light emitting diode is used as the light emitting element 7 and an infrared camera is used as the camera 3, the visitor or the like does not notice that the visitor or the like is being imaged. , Visitors and the like can be imaged by the camera. Further, since an infrared camera is used as the camera 3, a visitor or the like can be clearly imaged by imaging infrared reflected light that is emitted by the emission of the infrared light emitting diode and reflected by the visitor or the like.

Further, as the light emitting element 7, for example, a white light emitting element may be used.

In this case, it is preferable to use the camera 3 for color imaging.

As described above, when a white light emitting element is used as the light emitting element 7 and a color image pickup is used as the camera 3, a color monitor television is used as a master unit to be connected to the intercom unit 1 with a camera. With the equipment provided, the image of the visitor can be projected in color on the monitor television of the master unit.

The light emitting element 7 may be, for example, an infrared light emitting diode, and the camera 3 may be for color imaging.

When an infrared light emitting diode is used as the light emitting element 7 and a color image pickup is used as the camera 3, the light emitting element 7 is not turned on based on information detected by the light sensor (brightness sensor) 10. Sometimes, camera 3
When the light-emitting element 7 is turned on, the camera 3 is controlled so that the image taken by the camera 3 is converted to a black-and-white image and is displayed on the monitor TV of the master unit. Keep it.

When the control is performed in this manner, in the doorphone slave device 1 with a camera, when the subject (a visitor or the like) and its surroundings are dark and the light sensor (brightness sensor) 10 is turned on, the camera 3 Is switched to a black-and-white image, and a subject (a visitor or the like) is imaged. For this reason, even when a subject (a visitor or the like) and its surroundings are dark, and a subject (a visitor or the like) cannot be sufficiently imaged as a color image, this image is monitored by a master unit (not shown). TV (not shown)
In addition, it can be clearly projected in black and white video. Also, if the subject (such as a visitor) and its surroundings are bright,
Since the camera 3 is set to a color image to capture an image of an object (a visitor or the like), the object (a visitor or the like) is clearly displayed in a color image on a monitor television of a master unit (not shown). Can be.
