Description

  The present invention relates to an imaging apparatus having a camera unit that rotates about a pan rotation axis.

  2. Description of the Related Art Conventionally, an imaging apparatus such as a monitoring camera has been known that has a pan function for switching an imaging range.

  Patent Document 1 discloses a camera driven in the pan direction. This camera includes a flexible cable having one end fixed on the fixed portion side and the other end fixed on the rotating portion side. This flexible cable has at least a length necessary for the rotating operation of the rotating part and forms a U-shaped folded part, and the U-shaped folded part moves in accordance with the rotating operation of the rotating part. It is.

  Further, the configuration of another conventional imaging apparatus having a camera unit pan rotation function will be described with reference to FIG. Here, FIG. 7A is an exploded perspective view of the imaging apparatus 300, and FIG. 7B is a cross-sectional view of the imaging apparatus 300.

  An imaging apparatus 300 shown in FIG. 7 includes a camera unit 11 that captures an image of a subject and outputs a video signal inside an exterior 12 constituted by an upper case 12a and a lower case 12b, and a substrate 13 attached to the lower case 12b. And having. The imaging apparatus 300 further includes a connection portion 17 provided in the camera unit 11, a harness 14 connected to the connection portion 17 and the substrate 13, and an element 15.

  The harness 14 moves together with the connecting portion 17 as the camera unit 11 rotates in the pan direction around the rotation axis P. That is, the harness 14 moves in a space 18 surrounded by the exterior 12, the substrate 13, and the camera unit 11 with the rotation in the pan direction.

Japanese Patent Application Laid-Open No. 2004-191412

  However, in the camera disclosed in Patent Document 1, there is a possibility that the passage region of the flexible cable may extend over the entire circumference of the rotating shaft of the rotating unit. For this reason, if tall electronic components such as a transformer and a capacitor are arranged in the flexible cable housing space, the flexible cable may be caught by these electronic components. Further, if tall electronic components are disposed in the upper and lower spaces of the flexible cable housing space in order to avoid such a catch, there is a possibility that the height of the entire apparatus increases.

  Further, in the imaging apparatus 300 shown in FIG. 7, when a large (tall) element such as the element 15 is mounted on the substrate 13, the upper part of the element 15 (between the element 15 and the upper case 12a). Then, the space 18 in which the harness 14 moves becomes narrow. For this reason, when the camera unit 11 rotates in the pan direction and the harness 14 passes through the upper part of the element 15, the frictional force due to the contact between the harness 14 and the element 15 increases and the camera unit 11 rotates in the pan direction. In some cases, the load on the machine would increase.

  If such a load increases, there is a possibility that the camera unit 11 cannot be rotated in the pan direction to the desired imaging direction. Further, if the driving torque for rotating the camera unit 11 in the pan direction is set so that the camera unit 11 can be rotated in the pan direction even when such a load is large, the motor and gears become large and the image is taken. The apparatus 300 has become an obstacle to downsizing.

  Furthermore, if the exterior 12 is made smaller in order to make the imaging device 300 smaller, the space 18 for moving the harness 14 becomes narrower. In addition, the element 15 mounted on the substrate 13 becomes an obstacle that interferes with the harness 14, and the load applied to the drive system for rotating the camera unit 11 in the pan direction is increased.

  The present invention has been made in view of the above points. That is, an imaging apparatus having a camera unit that rotates about a pan rotation axis and a cable that is fixed at one end to the camera unit, and that is advantageous for downsizing without increasing the load caused by the movement of the cable. A device is provided.

  In order to achieve the above object, an imaging apparatus according to the present invention is provided with a housing, a camera unit that is rotatably supported by the housing around a pan rotation axis, and that fixes one end to the camera unit. An image pickup apparatus having a first cable and a board having a first region supported by the housing and provided with a first element, wherein the camera unit rotates about the pan rotation axis The rotation range is limited at both ends, and when the camera unit is located at both ends, a part of the cable is wound around the camera unit, and the camera unit is located between the both ends. Is characterized in that a bending portion is formed on the opposite side of the first region across the pan rotation shaft.

  According to the present invention, there is provided an imaging apparatus having a camera unit that rotates about a pan rotation axis and a cable having one end fixed to the camera unit, and is reduced in size without increasing a load caused by the movement of the cable. It is possible to provide an imaging device that is advantageous to

In addition, the element group 105 in this embodiment corresponds to a first element, and the element group 106 in this embodiment corresponds to a second element.

  The camera unit 101 images a subject and outputs a video signal. The output video signal is transmitted to the substrate 103 through the harness 104. The camera unit 101 is covered with a dome provided in the upper case 102a.

  Furthermore, the camera unit 101 includes a pan table 109, a lens cover 111 provided on the pan table 109, a tilt base 112, and a lens barrel unit 110 that is attached to the tilt base 112 so as to be rotatable in the tilt direction. Thereby, the lens barrel unit 110 can rotate in the tilt direction about the rotation axis T.

  The pan table 109 is attached to the lower case 102b so as to be rotatable in the pan direction. Thereby, the camera unit 101 can rotate in the pan direction around the rotation axis P. Here, the camera unit 101 in the present embodiment can rotate 360 ° in the pan direction. Note that the rotation axis P in this embodiment corresponds to a pan rotation axis.

  The lens barrel unit 110 is supported by the tilt base 112 so as to be rotatable in the tilt direction. The lens barrel unit 110 is covered with a lens cover 111. The lens cover 111 is disposed inside the upper case 102 a so as to cover the lens barrel unit 110 and the tilt base 112. Further, the lens cover 111 has a cutout portion that is cut out in accordance with the rotation operation of the lens barrel unit 110 in the tilt direction in order to secure the imaging field of view of the lens barrel unit 110.

  The lens cover 111 and the tilt base 112 are fixed to the pan table 109 and rotate integrally with the pan table 109 in the pan direction.

  The harness 104 is connected to a harness holding part 107 provided on the camera unit 101 and a board side connection part 108 provided on the board 103. Specifically, the harness 104 has one end fixed to the harness holding portion 107 and the other end fixed to the board side connection portion 108. Here, the harness holding portion 107 is a notch provided in the lens cover 111. The harness 104 is connected to the lens barrel unit 110 through the harness holding portion 107.

  As the camera unit 101 rotates in the pan direction, the harness 104 rotates in a space surrounded by the inner wall (inner periphery) of the exterior 102, the substrate 103, and the camera unit 101. The harness 104 is provided with a surplus portion having at least a length necessary for the rotation operation of the camera unit 101 in the pan direction. Moreover, the harness holding part 107 can be located in the rotation termination | terminus part A, when the camera unit 101 rotates in a pan direction.

  Note that the rotation end portion A in the present embodiment is an end portion of a rotation range in which the camera unit 101 rotates in the pan direction. Further, the board-side connecting portion 108 in the present embodiment corresponds to a fixed portion.

  Next, FIG. 4 shows that in this embodiment, when the camera unit 101 rotates in the pan direction, the harness holding portion 107 located at the rotation end portion A rotates 360 ° clockwise, and again the rotation end portion. It is the figure which showed the behavior of the harness 104 until it is located in A.

  In the present embodiment, both ends of the rotation range in which the camera unit 101 rotates in the pan direction are limited. Specifically, both ends of the rotation range are the rotation end portion A when the camera unit 101 rotates in the pan direction and counterclockwise, and the rotation end portion when the camera unit 101 rotates in the pan direction and clockwise. A. Note that “clockwise” in the present embodiment means clockwise when viewed from the upper surface of the imaging apparatus 100.

  In the state of FIG. 4A, the harness holding portion 107 is located at the rotation end portion A. At this time, the harness 104 is wound around a side wall (outer periphery) of the cylindrical portion of the lens cover 111. Because it is attached, it is in a state where there is little slack. When the camera unit 101 rotates clockwise from this state, as shown in FIGS. 4B, 4C, and 4D, the harness 104 rotates while forming a U-shaped bend 104a.

  For example, FIG. 4C shows the imaging device 100 in a state where the camera unit 101 is rotated 180 ° from the rotation end portion A in the pan direction and clockwise. In this state, the deflection 104a of the harness 104 becomes the largest. As the camera unit 101 further rotates in the pan direction and clockwise, the harness 104 gradually wraps around the lens cover 111 and the slackness of the harness 104 gradually decreases. As shown in FIG. 4C, the bending 104a of the harness 104 is formed on the opposite side of the region 114 with the rotation axis P interposed therebetween.

  Here, the broken-line region 114 is provided on the substrate 103 (on the substrate) and is located on the opposite side of the substrate-side connecting portion 108 with the rotation axis P interposed therebetween. Further, the region 114 is provided so as to face the rotation end portion A, in other words, provided on the same side as the rotation end portion A with respect to the rotation axis P. Note that the region 114 in the present embodiment corresponds to a first region.

  When the camera unit 101 further rotates in the pan direction, the harness holding portion 107 is again positioned at the rotation end portion A through the state of FIG. In this state, similarly to the state of FIG. 4A, the harness 104 is wound around the side wall of the cylindrical portion of the lens cover 111 and is in a state of less slack.

  The cylindrical portion of the lens cover 111 is a cylindrical portion that is coaxial with the rotation axis P.

  As described above, in the present embodiment, when the harness holding portion 107 is positioned at the rotation end portion A, the harness 104 is configured to be in a state of less slack. Thereby, even if the camera unit 101 rotates in the pan direction, the region 114 through which the harness 104 does not pass can be formed.

  Furthermore, in the present embodiment, the element group 105 is arranged in the region 114 where the harness 104 does not pass, and the element group 106 configured by elements shorter than the element group 105 in the other region (second region). Arranged. By arranging the elements in this way, the harness 104 that rotates as the camera unit 101 rotates in the pan direction passes through the upper part of the element group 106 but does not pass through the upper part of the element group 105. (In other words, the harness 104 passes through the space between the element group 106 and the upper case 102a, but does not pass through the space between the element group 105 and the upper case 102a.)

  Therefore, the harness 104 does not need to pass through a narrow space formed in the upper part of the element group 105 (between the element group 105 and the upper case 102a). For this reason, it is possible to prevent the pan driving load of the camera unit 101 from increasing due to the harness 104 being caught by the element group 105. Further, since it is not necessary to provide a separate space for allowing the harness 104 to pass above the tall element group 106 (between the element group 106 and the upper case 102a), it is possible to prevent the entire imaging apparatus 100 from becoming large.

Specifically, the harness 204 has one end fixed to the harness holding portion 207 and the other end fixed to the board side connection portion 208. Here, the harness holding portion 207 is a notch provided in the lens cover 211. The harness 204 is connected to the lens barrel unit 210 through the harness holding part 207.

  The harness 204 rotates in a space surrounded by the inner wall (inner periphery) of the exterior 202, the substrate 203, and the camera unit 201 as the camera unit 201 rotates in the pan direction. The harness 204 is provided with a surplus portion having at least a length necessary for the rotation operation of the camera unit 201 in the pan direction. Further, the harness holding unit 207 can be positioned at the rotation end portions A and A ′ as the camera unit 201 rotates in the pan direction.

  In the present embodiment, the rotation end portion A is one end portion of a rotation range in which the camera unit 201 rotates in the pan direction, and the rotation end portion A ′ is other than the rotation range in which the camera unit 201 rotates in the pan direction. It is an end. Therefore, the position of the rotation end portion A and the position of the rotation end portion A ′ are different from each other.
