JP 2001-346074 A (page 3-9, FIG. 1)

しかしながら、従来の装置では、天井面から壁面へカメラ設置面の切替えを行うときに、取付部材を回転させて取付突出部を貫通孔から外側へ突出させるために、装置を分解する必要がある。したがって、カメラ設置面の切替えを行うときの作業に手間や労力がかかるという問題があった。   However, in the conventional device, when the camera installation surface is switched from the ceiling surface to the wall surface, it is necessary to disassemble the device in order to rotate the mounting member and project the mounting projection from the through hole. Therefore, there has been a problem that work and labor are required for switching the camera installation surface.

本発明は、上記従来の問題を解決するためになされたもので、カメラ設置面の切替えを容易に行うことのでき、様々なカメラ設置面に対応可能なカメラ装置を提供することを目的とする。   The present invention has been made to solve the above-described conventional problems, and it is an object of the present invention to provide a camera device that can easily switch the camera installation surface and can handle various camera installation surfaces. .

本発明のカメラ装置は、カメラと、前記カメラをカメラ設置面に取り付けるための取付面を有する取付部とを備え、前記取付面は、前記カメラに対して所定の回転軸を中心にして相対的に回転可能であり、前記回転軸は、前記カメラのチルト旋回面上において、前記カメラのパン軸に対して第１の角度で設けられており、前記取付面は、前記回転軸の垂直面に対して第２の角度で設けられた構成を有している。   The camera device of the present invention includes a camera and an attachment portion having an attachment surface for attaching the camera to a camera installation surface, and the attachment surface is relative to the camera around a predetermined rotation axis. The rotation axis is provided at a first angle with respect to the pan axis of the camera on the tilt rotation surface of the camera, and the mounting surface is perpendicular to the rotation axis. On the other hand, it has a configuration provided at a second angle.

この構成により、回転軸を中心にして取付面を回転させて、カメラ設置面に応じて取付面の角度を調整することが可能になる。これにより、カメラ装置を分解することなく、カメラ設置面の切替えを容易に行うことのでき、様々なカメラ設置面に対応することができるようになる。   With this configuration, the mounting surface can be rotated about the rotation axis, and the angle of the mounting surface can be adjusted according to the camera installation surface. Accordingly, the camera installation surface can be easily switched without disassembling the camera device, and various camera installation surfaces can be handled.

また、本発明のカメラ装置では、前記第１の角度および前記第２の角度は、４５度に設定された構成を有している。   In the camera device of the present invention, the first angle and the second angle are set to 45 degrees.

この構成により、回転軸を中心にして取付面を回転させて、取付面の角度がパン軸と平行になるように調整することができ、垂直な壁面への取付けが可能になる。また、回転軸を中心にして取付面を回転させて、取付面の角度がパン軸と垂直になるように調整することができ、水平な天井面への取付けが可能になる。   With this configuration, the attachment surface can be rotated about the rotation axis so that the angle of the attachment surface can be adjusted to be parallel to the pan axis, and attachment to a vertical wall surface becomes possible. Further, the mounting surface can be rotated around the rotation axis so that the angle of the mounting surface can be adjusted to be perpendicular to the pan axis, and mounting on a horizontal ceiling surface becomes possible.

また、本発明のカメラ装置では、前記回転軸が、前記パン軸と前記チルト軸との交点を通るように設けられた構成を有している。   In the camera device of the present invention, the rotation axis is provided so as to pass through the intersection of the pan axis and the tilt axis.

この構成により、回転軸を中心にして取付面を回転させて、カメラ設置面に応じて取付面の角度を調整したときに、カメラの相対的な位置が保たれる。これにより、取付面の角度を調整してカメラ設置面を切り替えたときに、カメラ位置が変わるのを防ぐことができる。   With this configuration, when the mounting surface is rotated about the rotation axis and the angle of the mounting surface is adjusted according to the camera installation surface, the relative position of the camera is maintained. Thereby, it is possible to prevent the camera position from changing when the angle of the mounting surface is adjusted to switch the camera installation surface.

また、本発明のカメラ装置では、前記取付面は、前記カメラのパン軸の向きが鉛直方向になるように、前記カメラに対して所定の回転角度だけ一の方向に回転されているとともに、前記カメラ設置面に対して前記回転角度だけ前記一の方向の逆方向に回転されている構成を有している。   In the camera device of the present invention, the mounting surface is rotated in one direction by a predetermined rotation angle with respect to the camera so that a direction of a pan axis of the camera is a vertical direction. It is configured to be rotated in the direction opposite to the one direction by the rotation angle with respect to the camera installation surface.

この構成により、カメラのパン軸Ｐの向きが鉛直方向になるように、取付面をカメラに対して回転させるとともに、その分だけカメラ設置面に対して逆回転させて、取付面の角度を調整することができる。これにより、様々なカメラ設置面に対応することができるようになる。この場合、カメラ設置面を切り替えたときに、カメラの向きが変わるのを防ぐことができる。   With this configuration, the mounting surface is rotated with respect to the camera so that the direction of the pan axis P of the camera is in the vertical direction, and the angle of the mounting surface is adjusted by rotating the mounting surface reversely with respect to the camera installation surface. can do. Thereby, it becomes possible to deal with various camera installation surfaces. In this case, the camera orientation can be prevented from changing when the camera installation surface is switched.

また、本発明のカメラ装置では、前記回転角度の基準を示す基準部を備えた構成を有している。   Further, the camera device of the present invention has a configuration provided with a reference portion indicating the reference of the rotation angle.

この構成により、取付面やカメラ設置面に対してカメラを回転させるときに、基準部を基準にすることができ、角度の調整作業が容易になる。   With this configuration, when the camera is rotated with respect to the mounting surface or the camera installation surface, the reference portion can be used as a reference, and the angle adjustment operation is facilitated.

本発明は、回転軸を中心にして相対的に回転可能な取付面を設けることにより、カメラ設置面の切替えを容易に行うことのでき、様々なカメラ設置面に対応することができるという効果を有するカメラ装置を提供することができるものである。   The present invention provides an effect that the camera installation surface can be easily switched by providing a mounting surface relatively rotatable about the rotation axis, and can be applied to various camera installation surfaces. The camera apparatus which has can be provided.

図１〜図３に示すように、カメラ装置１は、パン方向とチルト方向に回転可能なカメラ２と、カメラ２の上部に設けられる支持板３と、支持板３に対して回転可能に取り付けられる取付板４を備えている。取付板４は、ベース板５に固定されており、ベース板５が、カメラ設置面（天井面や壁面など）に取り付けられている。すなわち、カメラ２は、支持板３、取付板４、ベース板５を介して、カメラ設置面（天井面や壁面など）に取り付けられているともいえる。   As shown in FIGS. 1 to 3, the camera device 1 is attached to a camera 2 that can rotate in a pan direction and a tilt direction, a support plate 3 provided on the top of the camera 2, and a support plate 3 that can rotate. The mounting plate 4 is provided. The mounting plate 4 is fixed to the base plate 5, and the base plate 5 is attached to a camera installation surface (such as a ceiling surface or a wall surface). That is, it can be said that the camera 2 is attached to the camera installation surface (ceiling surface, wall surface, etc.) via the support plate 3, the attachment plate 4, and the base plate 5.

カメラ２の内部には、カメラ２をパン軸Ｐを中心に回転させるためのパン用モータ（図示せず）と、カメラ２をチルト軸Ｔを中心に回転させるためのチルト用モータ（図示せず）が備えられている。図１および図２の例では、パン軸Ｐが紙面に平行（紙面上）であり、チルト軸Ｔが紙面に垂直である。チルト旋回面が紙面と同一面であるともいえる。   Inside the camera 2, a pan motor (not shown) for rotating the camera 2 around the pan axis P and a tilt motor (not shown) for rotating the camera 2 around the tilt axis T are provided. ) Is provided. In the example of FIGS. 1 and 2, the pan axis P is parallel to the paper surface (on the paper surface), and the tilt axis T is perpendicular to the paper surface. It can be said that the tilt turning surface is the same surface as the paper surface.

図１および図２に示すように、支持板３は、カメラ２の上部に固定される本体部６と、本体部６から屈曲して延びる屈曲部７を備えている。本体部６は、パン軸Ｐに垂直であり、屈曲部７は、本体部６に対して４５°の角度で設けられている。この屈曲部７に、取付板４が回転可能に取り付けられる。   As shown in FIGS. 1 and 2, the support plate 3 includes a main body 6 that is fixed to the upper part of the camera 2 and a bent portion 7 that is bent and extends from the main body 6. The main body 6 is perpendicular to the pan axis P, and the bent portion 7 is provided at an angle of 45 ° with respect to the main body 6. The mounting plate 4 is rotatably attached to the bent portion 7.

取付板４は、支持板３の屈曲部７に回転可能に取り付けられる回転取付部８と、カメラ設置面に取り付けられる取付部９を備えている。この回転取付部８は、取付部９に対して４５°の角度で設けられている。取付板４の回転取付部８は、支持板３の屈曲部７に対して回転軸Ｘを中心にして回転可能である。すなわち、取付板４が、支持板３とカメラ２に対して回転軸Ｘを中心にして相対的に回転可能であるともいえる。なお、この取付板４の取付部９には、カメラ設置面に取り付けるための平面状の部分（取付面）が設けられている。   The mounting plate 4 includes a rotation mounting portion 8 that is rotatably mounted on the bent portion 7 of the support plate 3 and a mounting portion 9 that is mounted on the camera installation surface. The rotation attachment portion 8 is provided at an angle of 45 ° with respect to the attachment portion 9. The rotation attachment portion 8 of the attachment plate 4 is rotatable about the rotation axis X with respect to the bent portion 7 of the support plate 3. In other words, it can be said that the mounting plate 4 is rotatable relative to the support plate 3 and the camera 2 around the rotation axis X. The mounting portion 9 of the mounting plate 4 is provided with a planar portion (mounting surface) for mounting on the camera installation surface.

この回転軸Ｘは、カメラ２のパン軸Ｐを含むチルト旋回面上において、パン軸Ｐに対して第１の角度α（ここでは、α＝４５°）で斜めに設けられているともいえる。また、取付面は、回転軸Ｘの垂直面に対して第２の角度β（ここでは、β＝４５°）で斜めに設けられているともいえる。そして、図１および図２に示すように、回転軸Ｘは、パン軸Ｐとチルト軸Ｔの交点を通るような位置に設けられている。   It can be said that the rotation axis X is provided obliquely with respect to the pan axis P at a first angle α (here, α = 45 °) on the tilt turning surface including the pan axis P of the camera 2. It can also be said that the mounting surface is provided obliquely with respect to the vertical plane of the rotation axis X at a second angle β (here, β = 45 °). As shown in FIGS. 1 and 2, the rotation axis X is provided at a position passing through the intersection of the pan axis P and the tilt axis T.

以上のように構成されたカメラ装置１について、図面を用いてその動作を説明する。   About the camera apparatus 1 comprised as mentioned above, the operation | movement is demonstrated using drawing.

（天井面への取付）
本実施の形態のカメラ装置１を天井面に取り付けるときには、まず、ベース板５を天井面へ取り付ける。なお、カメラ装置１の取付前の段階では、支持板３と取付板４はカメラ２に取り付けられており、ベース板５のみが別体になっている。 (Mounting on the ceiling)
When the camera device 1 of the present embodiment is attached to the ceiling surface, first, the base plate 5 is attached to the ceiling surface. In the stage before the camera device 1 is attached, the support plate 3 and the attachment plate 4 are attached to the camera 2, and only the base plate 5 is separate.

つぎに、天井面に固定されたベース板５に取付板４を取り付ける。つまり、取付板４と支持板３を介して、カメラ２をベース板５に取り付ける。そして、カメラ２を取付板４に対して相対的に回転させて、カメラ２の向きを水平方向に設定する（図１参照）。すなわち、パン軸Ｐの向きが鉛直方向に設定される。   Next, the attachment plate 4 is attached to the base plate 5 fixed to the ceiling surface. That is, the camera 2 is attached to the base plate 5 via the attachment plate 4 and the support plate 3. Then, the camera 2 is rotated relative to the mounting plate 4 to set the orientation of the camera 2 in the horizontal direction (see FIG. 1). That is, the direction of the pan axis P is set to the vertical direction.

（壁面への取付）
天井面へ取り付けられていたカメラ装置１を壁面に付け替えるときには、まず、取付板４をベース板５から取り外す。そして、カメラ２から取り外したベース板５を壁面へ取り付ける。 (Wall mounting)
When the camera device 1 attached to the ceiling surface is replaced with a wall surface, first, the attachment plate 4 is removed from the base plate 5. Then, the base plate 5 removed from the camera 2 is attached to the wall surface.

つぎに、壁面に固定されたベース板５に取付板４を取り付ける。つまり、取付板４と支持板３を介して、カメラ２をベース板５に取り付ける。そして、カメラ２を取付板４に対して相対的に回転させて、カメラ２の向きを水平方向に設定する（図２参照）。この場合、取付板４をカメラ２に対して相対的に１８０°回転させる。このようにして、パン軸Ｐの向きが鉛直方向に設定される。   Next, the attachment plate 4 is attached to the base plate 5 fixed to the wall surface. That is, the camera 2 is attached to the base plate 5 via the attachment plate 4 and the support plate 3. Then, the camera 2 is rotated relative to the mounting plate 4 to set the orientation of the camera 2 in the horizontal direction (see FIG. 2). In this case, the mounting plate 4 is rotated by 180 ° relative to the camera 2. In this way, the direction of the pan axis P is set to the vertical direction.

（斜め壁面への取付）
つづいて、本実施の形態のカメラ装置１を斜め壁面に取り付けるときの動作について、図４および図５を用いて説明する。図４は、斜め壁面に設置したときのカメラ装置１の側面図であり、図５は、斜め壁面に設置したときのカメラ装置１の説明図である。ここでは、斜め壁面の角度が６０°の場合を例示して説明する。 (Mounting on an oblique wall)
Next, an operation when the camera device 1 of the present embodiment is attached to an oblique wall surface will be described with reference to FIGS. 4 and 5. 4 is a side view of the camera device 1 when installed on an oblique wall surface, and FIG. 5 is an explanatory diagram of the camera device 1 when installed on an oblique wall surface. Here, a case where the angle of the oblique wall surface is 60 ° will be described as an example.

図４および図５に示すように、斜め壁面にカメラ装置１を取り付けるときには、まず、斜め壁面の角度（例えば６０°）に応じて、取付板４をカメラ２に対して相対的に所定の回転角度θ（例えば９０°）だけ正方向（例えば図５における左回り方向）に回転させる。   As shown in FIGS. 4 and 5, when the camera device 1 is attached to the oblique wall surface, first, the attachment plate 4 is rotated relative to the camera 2 by a predetermined rotation according to the angle of the oblique wall surface (for example, 60 °). It is rotated in the positive direction (for example, counterclockwise in FIG. 5) by an angle θ (for example, 90 °).

ここで、カメラ２の回転角度θについて説明する。カメラ２を取付板４に対して相対的に回転させると、その回転角度に応じてカメラ２は取付板４に対して上向きになる。この回転角度θは、斜め壁面の角度に応じて、カメラ２のパン軸Ｐの向きが鉛直方向になるように設定される。以下の表に、カメラ２の回転角度θと取付板４に対するカメラ２の角度（仰角）との関係を示す。   Here, the rotation angle θ of the camera 2 will be described. When the camera 2 is rotated relative to the mounting plate 4, the camera 2 faces upward with respect to the mounting plate 4 according to the rotation angle. This rotation angle θ is set so that the direction of the pan axis P of the camera 2 is the vertical direction according to the angle of the oblique wall surface. The following table shows the relationship between the rotation angle θ of the camera 2 and the angle (elevation angle) of the camera 2 with respect to the mounting plate 4.

Figure 0004800281
Figure 0004800281

図５に示すように、斜め壁面にベース板５を取り付けるときには、斜め壁面の角度（例えば６０°）に応じた回転角度θ（例えば９０°）だけ逆方向（例えば図５における右回り方向）に回転させた状態で取り付ける。つぎに、斜め壁面に固定されたベース板５に取付板４を取り付ける。そして、カメラ２を取付板４に対して回転角度θだけ正方向に回転させる。このようにして、パン軸Ｐの向きが鉛直方向になり、カメラ２の向きが正面方向（図５の上方向）に設定される。   As shown in FIG. 5, when the base plate 5 is attached to an oblique wall surface, the rotation angle θ (for example, 90 °) corresponding to the angle of the oblique wall surface (for example, 60 °) is reversed (for example, clockwise in FIG. 5). Install in a rotated state. Next, the attachment plate 4 is attached to the base plate 5 fixed to the oblique wall surface. Then, the camera 2 is rotated in the positive direction with respect to the mounting plate 4 by the rotation angle θ. In this way, the direction of the pan axis P is set to the vertical direction, and the direction of the camera 2 is set to the front direction (upward direction in FIG. 5).

図６は、本実施の形態のカメラ装置１の変形例を示す図である。図６に示すように、カメラ装置１には、カメラ２を取付板４に対して回転させるときの回転角度θの基準になる第１目盛り部１０が設けられている。また、ベース板５とカメラ設置面との間に基準板１１が設けられており、ベース板５と基準板１１には、カメラ２をカメラ設置面に対して回転させるときの回転角度θの基準になる第２目盛り部１２が設けられている。この第１目盛り部１０および第２目盛り部１２は、本発明の基準部に相当する。   FIG. 6 is a diagram illustrating a modification of the camera device 1 according to the present embodiment. As shown in FIG. 6, the camera device 1 is provided with a first scale portion 10 that serves as a reference for the rotation angle θ when the camera 2 is rotated with respect to the mounting plate 4. In addition, a reference plate 11 is provided between the base plate 5 and the camera installation surface, and the base plate 5 and the reference plate 11 have a reference for a rotation angle θ when the camera 2 is rotated with respect to the camera installation surface. The second scale portion 12 is provided. The first scale portion 10 and the second scale portion 12 correspond to the reference portion of the present invention.

図６に示したカメラ装置１を斜め壁面に取り付けるときには、まず、斜め壁面に基準板１１を取り付ける。そして、第２目盛り部１２を参照して、斜め壁面の角度（例えば６０°）に応じた回転角度θだけ逆方向に回転させた状態でベース板５を基準板１１に取り付ける。つぎに、基準板１１に固定されたベース板５に取付板４を取り付ける。そして、第１目盛り部１０を参照して、斜め壁面の角度（例えば６０°）に応じた回転角度θだけカメラ２を取付板４に対して正方向に回転させる。   When the camera device 1 shown in FIG. 6 is attached to an oblique wall surface, first, the reference plate 11 is attached to the oblique wall surface. Then, with reference to the second scale portion 12, the base plate 5 is attached to the reference plate 11 while being rotated in the reverse direction by the rotation angle θ according to the angle of the oblique wall surface (for example, 60 °). Next, the attachment plate 4 is attached to the base plate 5 fixed to the reference plate 11. Then, with reference to the first scale portion 10, the camera 2 is rotated in the forward direction with respect to the mounting plate 4 by a rotation angle θ corresponding to the angle of the oblique wall surface (for example, 60 °).

このような本発明の実施の形態のカメラ装置１によれば、回転軸Ｘを中心にして相対的に回転可能な取付面を設けることにより、カメラ設置面（天井面や壁面など）の切替えを容易に行うことのでき、様々なカメラ設置面に対応することができる。   According to such a camera device 1 of the embodiment of the present invention, by providing a mounting surface relatively rotatable around the rotation axis X, the camera installation surface (ceiling surface, wall surface, etc.) can be switched. It can be easily performed, and can correspond to various camera installation surfaces.

すなわち、本実施の形態では、回転軸Ｘを中心にして取付面を回転させて、カメラ設置面に応じて取付面の角度を調整することができる。これにより、カメラ装置１を分解することなく、カメラ設置面の切替えを容易に行うことのでき、様々なカメラ設置面に対応することができるようになる。   That is, in the present embodiment, the attachment surface can be rotated about the rotation axis X, and the angle of the attachment surface can be adjusted according to the camera installation surface. Thereby, it is possible to easily switch the camera installation surface without disassembling the camera device 1, and it is possible to deal with various camera installation surfaces.

例えば、回転軸Ｘを中心にして取付面を回転させて、取付面の角度がパン軸Ｐと平行になるように調整することができる。これにより、垂直な壁面への取付けが可能になる。また、回転軸Ｘを中心にして取付面を回転させて、取付面の角度がパン軸Ｐと垂直になるように調整することができる。これにより、水平な天井面への取付けが可能になる。   For example, the attachment surface can be rotated about the rotation axis X, and the angle of the attachment surface can be adjusted to be parallel to the pan axis P. Thereby, the attachment to a vertical wall surface is attained. In addition, the attachment surface can be rotated about the rotation axis X so that the angle of the attachment surface is perpendicular to the pan axis P. Thereby, the installation to a horizontal ceiling surface is attained.

また、この場合、回転軸Ｘを中心にして取付面を回転させて、カメラ設置面に応じて取付面の角度を調整したときに、カメラ２の相対的な位置が保たれる。これにより、取付面の角度を調整してカメラ設置面を切り替えたときに、カメラ位置が変わるのを防ぐことができる。すなわち、カメラ位置が、上下左右にずれるのを防ぐことができる。   In this case, when the mounting surface is rotated about the rotation axis X and the angle of the mounting surface is adjusted according to the camera installation surface, the relative position of the camera 2 is maintained. Thereby, it is possible to prevent the camera position from changing when the angle of the mounting surface is adjusted to switch the camera installation surface. That is, it is possible to prevent the camera position from shifting vertically and horizontally.
