Description

Description: TECHNICAL FIELD The present invention relates to an improvement of a monitor camera and a direction adjusting device for detecting a human body. [Background Art] Conventionally, a direction adjusting device has been used to direct a security sensor, a monitor camera, and the like to an appropriate position according to a subject, but a conventional structure has a structure as shown in FIG. In addition, a base 101 is attached to a ceiling 100, a wall surface, or the like, and a head 102 having a built-in sensor can be rotated and tilted within a predetermined range to adjust in a free direction. However, since such a conventional direction adjusting device has a structure in which the base is mounted on a ceiling or a wall surface and the head is exposed in any form, the existence thereof is conspicuous, which is preferable for security. And the equipment was also upsized. [Object of the Invention] The present invention has been developed in view of such circumstances, and is not noticeable even when attached, and furthermore, a monitor camera or a human body that can position the head within a predetermined range and in any direction. It is an object to provide a direction adjustment device for a detector. DISCLOSURE OF THE INVENTION The direction adjusting device for a monitor camera of the present invention proposed to achieve the above object is provided with a drive unit, and a base adapted to cover a cylindrical cover having an opening at an upper part thereof.
A dome-shaped head having a built-in monitor camera is pivotally attached to the upper cover via a mounting column so that the base can be rotated and the head can be tilted and adjusted. In addition, the human body detection direction adjusting device of the present invention proposed at the same time incorporates a monitor camera via a mounting column on a base on which a driving unit is mounted and a cylindrical cover having an opening on an upper portion is covered. The dome-shaped head is pivotally mounted so as to protrude from the upper cover, so that the base can be rotated and the head can be tilted and adjusted. Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a partially cutaway perspective view of a dome-shaped head showing a main structure of a direction adjusting device for a monitor camera according to the present invention, FIGS. 2 and 3 are longitudinal sectional structures, and FIG. It is a figure showing a plane. Reference numeral 1 denotes a disc-shaped base on which a driving unit described later is mounted,
Two mounting support plates 3, 3 are fixed to the peripheral edge of the base 1, and the base of the dome-shaped head 2 is pivotally connected to the end of the support plates 3, 3 at the end thereof. , 3a. The dome-shaped head 2 has a window hole 2a for allowing the sensor to face an appropriate position of the dome main body, and a space inside the dome body has a monitor camera built therein, as shown in FIG.
A mounting base 2b is provided, and a monitor camera (not shown) is mounted on the mounting base 2b to mount a printed circuit board required for control. The drive unit mounted on the base 1 attaches two step motors 6 and 7 to the base 1, and each of the step motors 6 and 7 tilts the first gear mechanism 4 for rotating the base 1 and the head 2. The rotation force is transmitted to the second gear mechanism 5 to be rotated. As shown in FIG. 2, the first gear mechanism 4 meshes a worm 61 attached to the rotating shaft of the step motor 6 with a worm wheel 41 fixed to a projection 42 fixed to a cylinder bottom 81. And a support cylinder fixed to the base 1 side
43 is rotatable with respect to the protruding portion 42 via a bearing 44. For this reason, when the step motor 6 is rotated forward and backward, the base 1 is configured to rotate right and left around the protrusion 42. In order to prevent continuous rotation of the base 1 by the first gear mechanism 4, a detection means such as a proximity switch is provided between the base 1 and the cylinder bottom 81 to define the start and end positions during forward and reverse rotation. I have. As shown in FIGS. 2 to 4, the second gear mechanism 5 has another worm wheel 41 attached to the base 1 so as to face the step motor 6 with the worm wheel 41 interposed therebetween. Worm fixed to the rotating shaft of the step motor 7
The 71 is rotatably supported on the two support plates 3, 3 described above.
A gear 52 fixed to the end of the shaft 53 is further meshed with a gear 55 fixed to the head 2 by bolts and nuts 56. ing. The base 1 has an opening as described above.
A cylinder cover 8 having a cylinder cover 8 is mounted thereon. The cylinder cover 8 is fixed to a cylinder bottom 81 fixed to the base 1 with a screw 83 or the like. It has a more protruding structure. In order to prevent the tilt control of the head 2 by the second gear mechanism 5 from being performed beyond an allowable range, the head 2
The base 1 is provided with detection means such as a proximity switch to define the start and end positions of the tilt range. According to the direction adjusting device for a monitor camera of the present invention having such a structure, when the stepping motor 6 is driven forward and reverse,
Since the base 1 rotates in the directions A and A '(see FIG. 1),
The head 2 also rotates with this. When the stepping motor 7 is driven forward and backward, the head 2 tilts in the directions B and B '(see FIG. 1). Therefore, the head 2 can be arbitrarily controlled through forward and reverse rotation control of these stepping motors 6 and 7. rotation,
Can be positioned as tilting. Further, according to such a monitor camera direction adjusting device, since the vertical position of the window 2a provided in the head 2 can always be kept constant and directed toward the subject, the monitor camera incorporated in the head 2 can be An appropriate monitor image can be obtained without inverting the image signal. FIG. 5 shows an example of the use of the direction adjusting device for a monitor camera of the present invention. If the entire cylinder cover 8 is embedded in a wall, only the head 2 is exposed from the wall surface 10, so that the conventional device is used. It is not noticeable during installation. In the present invention as described above, if the optimum position of the monitor camera is stored in advance by a microcomputer or the like, the same positioning can always be reproduced. In addition, if a system linked to other sensors is configured by a microcomputer, the head is oriented to the optimum position according to the other sensors, and the monitor camera built in the head is oriented in the optimum direction to the subject. Can be positioned. In the above description, only the direction adjustment device for the monitor camera has been described, but the direction adjustment device for the human body detector is also structurally the same, and a human body detector such as a heat ray detector is mounted instead of the monitor camera. . According to the direction adjusting device for a monitor camera human body detector of the present invention, a base on which a drive unit is mounted is housed in a cylinder cover, and the cylinder cover is embedded in a wall or a ceiling, and only a head is mounted. Since it can be used by protruding, it is not noticeable at the time of mounting, and the apparent size can be reduced.
