Abstract

<P>PROBLEM TO BE SOLVED: To provide a monitor prevented from causing twisting or winding to occur in wires led out of a detector even if the direction of the detector is turned ≥360°. <P>SOLUTION: In this monitor 1, the detector 80 is turned around a second axis line L2 extending in a direction crossing a first axis line L1 substantially parallel to a direction L0 with the detector 80 facing therein. In this event, the detector 80 is caused to make one turn around the axis line L1 in the direction opposite to the turn around the axis line L2 while the detector 80 makes one turn around the axis line L2 when viewed from the axis line L2. That is, when viewing the monitor 1 from the exterior, the detector 80 does not turn around the axis line L1 when turning around the axis line L2 but it turns around the axis line L2 with it kept directed in the same angular direction around the axis line L1. Accordingly, twisting or winding is prevented from occurring in the wires 83 led out of the detector 80. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

本発明は、各種センサや撮像装置などといった検出器の向きを切り換えることのできる監視装置に関するものである。   The present invention relates to a monitoring device capable of switching the direction of a detector such as various sensors or an imaging device.
従来、赤外線センサや撮像装置などといった検出器の向きを360°以上にわたって切り換える監視装置としては、モータの出力軸にホルダなどを介して赤外線センサを連結し、モータによってホルダとともに赤外線センサをモータ軸線周りに回転させる構成が知られている(特許文献1参照)。
特開平9−72781号公報
Conventionally, as a monitoring device for switching the direction of a detector such as an infrared sensor or an imaging device over 360 ° or more, an infrared sensor is connected to a motor output shaft through a holder or the like, and the infrared sensor is moved around the motor axis along with the holder by the motor A configuration in which the rotation is performed is known (see Patent Document 1).
Japanese Patent Laid-Open No. 9-72781
しかしながら、上記特許文献1に開示の構成では、赤外線センサが1回転すると、赤外線センサから引き出されている配線も1回転するため、赤外線センサの向きを繰り返し切り換えると、配線がモータ出力軸などに巻き付いてしまうという問題点がある。   However, in the configuration disclosed in Patent Document 1, when the infrared sensor rotates once, the wiring drawn from the infrared sensor also rotates once. Therefore, when the direction of the infrared sensor is repeatedly switched, the wiring is wound around the motor output shaft or the like. There is a problem that.
以上の問題点に鑑みて、本発明の課題は、検出器の向きを360°以上回転させた場合でも、検出器から引き出された配線に捩れや巻き付きが発生することのない監視装置を提供することにある。   In view of the above problems, an object of the present invention is to provide a monitoring device that does not cause twisting or wrapping in wiring drawn from a detector even when the direction of the detector is rotated 360 ° or more. There is.
上記課題を解決するために、本発明では、配線が引き出された検出器と、該検出器の向きを切り換える駆動装置とを有する監視装置において、前記検出器が向いている方向、前記検出器が向いている方向と平行、あるいは前記検出器が向いている方向と所定の角度を成す軸線を第1の軸線とし、当該第1の軸線および前記検出器が向いている方向と交差する方向に延びた軸線を第2の軸線としたとき、前記駆動装置は、前記検出器に前記第2の軸線周りの回転を行わせるとともに、前記第2の軸線からみたとき、前記第2の軸線周りの回転を1回行う間に前記検出器に前記第1の軸線周りの回転を1回、前記第2の軸線周りの回転とは逆方向に行わせることを特徴とする。   In order to solve the above problems, in the present invention, in a monitoring device having a detector from which wiring is drawn out and a drive device that switches the direction of the detector, the direction in which the detector is facing, the detector An axis that is parallel to the direction that faces or that forms a predetermined angle with the direction that the detector faces is defined as a first axis, and extends in a direction that intersects the first axis and the direction that the detector faces. The driving device causes the detector to rotate around the second axis when viewed from the second axis, and the rotation around the second axis when viewed from the second axis. In this case, the detector is rotated once around the first axis in the opposite direction to the rotation around the second axis.
本発明に係る監視装置において、駆動装置によって、検出器を第2の軸線周りに回転させると、検出器の向きが切り換わる。その際、第2の軸線からみると、検出器は、第2の軸線周りの回転を1回行う間に第1の軸線周りの回転を1回、第2の軸線周りの回転とは逆方向に行う。このため、検出器が第2の軸線周りの回転を行う前後において、検出器からみて配線は、第1の軸線に対して常に同一方向に位置する。このため、検出器の向きを360°以上にわたって回転させても、検出器から引き出された配線が捩れることがなく、巻き付くこともない。   In the monitoring device according to the present invention, when the detector is rotated around the second axis by the driving device, the direction of the detector is switched. At this time, when viewed from the second axis, the detector rotates once around the first axis once during the rotation around the second axis, and in the direction opposite to the rotation around the second axis. To do. For this reason, before and after the detector rotates around the second axis, the wiring is always located in the same direction with respect to the first axis as viewed from the detector. For this reason, even if the direction of the detector is rotated over 360 ° or more, the wiring drawn from the detector is not twisted and does not wind.
本発明において、前記駆動装置は、前記検出器を保持した状態で前記第1の軸線方向に延びた軸体と、モータと、該モータの回転出力を前記軸体に伝達して当該軸体に前記第2の軸線周りの公転を行わせるための伝達部材と、前記第2の軸線から半径方向に離間した位置で前記第1の軸線周りの自転を許容した状態で前記軸体と前記伝達部材とを連結する連結機構と、前記自転および前記公転を許容した状態で前記軸体を支持する軸受機構とを備えていることが好ましい。このように構成すると、前記軸体は、前記第1の軸線周りにおける同一の角度方向を向いたまま前記公転を行うことにより、前記第2の軸線からみたとき、前記第2の軸線周りの公転を1回行う間に当該公転とは逆方向に前記自転を1回、自動的に行う。従って、軸体の1公転動作中に軸体を自転させるための駆動系が不要である。それ故、監視装置を小型かつ安価に構成することができる。   In the present invention, the driving device transmits a shaft body extending in the first axial direction while holding the detector, a motor, and a rotation output of the motor to the shaft body to the shaft body. A transmission member for causing revolution around the second axis, and the shaft body and the transmission member in a state in which rotation around the first axis is allowed at a position spaced apart from the second axis in the radial direction; And a bearing mechanism that supports the shaft body in a state in which the rotation and the revolution are allowed. With this configuration, the shaft body performs the revolution while facing the same angular direction around the first axis, so that when viewed from the second axis, the revolution about the second axis is performed. The rotation is automatically performed once in the direction opposite to the revolution while the rotation is performed once. Accordingly, there is no need for a drive system for rotating the shaft body during one revolution of the shaft body. Therefore, the monitoring device can be configured in a small and inexpensive manner.
本発明において、前記モータの出力軸は、前記第2の軸線上に位置し、前記軸受機構は、前記第2の軸線と前記軸体との交差部分に構成されていることが好ましい。このように構成すると、監視装置を小型に構成することができる。   In this invention, it is preferable that the output shaft of the said motor is located on the said 2nd axis, and the said bearing mechanism is comprised in the cross | intersection part of the said 2nd axis and the said shaft body. If comprised in this way, a monitoring apparatus can be comprised small.
本発明において、前記連結機構は、前記軸体および前記伝達部材のうちの一方に形成された連結機構用球部と、他方側で当該連結機構用球部を受ける連結機構用受け部とを備え、前記軸受機構は、前記軸体、および固定された支持板のうちの一方に形成された軸受機構用球部と、他方側で当該軸受機構用球部を受ける軸受機構用受け部とを備えていることが好ましい。このように構成すると、小型で簡素な構成で、各方向への回転を許容する連結機構や軸受機構を構成することができる。   In the present invention, the connection mechanism includes a connection mechanism ball portion formed on one of the shaft body and the transmission member, and a connection mechanism receiving portion that receives the connection mechanism ball portion on the other side. The bearing mechanism includes a bearing mechanism ball portion formed on one of the shaft body and the fixed support plate, and a bearing mechanism receiving portion receiving the bearing mechanism ball portion on the other side. It is preferable. If comprised in this way, the connection mechanism and bearing mechanism which allow the rotation to each direction can be comprised with a small and simple structure.
本発明において、前記連結機構は前記軸体の一方端側に構成され、前記検出器は前記軸体の他方端側で保持され、前記軸受機構は前記軸体の長さ方向における途中位置に配置されていることが好ましい。このように構成すると、モータは小さな力で軸体を公転させることができる。   In the present invention, the coupling mechanism is configured on one end side of the shaft body, the detector is held on the other end side of the shaft body, and the bearing mechanism is disposed at an intermediate position in the length direction of the shaft body. It is preferable that If comprised in this way, a motor can revolve a shaft with a small force.
本発明に係る監視装置において、駆動装置によって、検出器を第2の軸線周りに回転させると、検出器の向きが切り換わる。その際、第2の軸線からみると、検出器は、第2の軸線周りの回転を1回行う間に第1の軸線周りの回転を1回、第2の軸線周りの回転とは逆方向に行う。このため、検出器が第2の軸線周りの回転を行う前後において、検出器からみて配線は、第1の軸線に対して常に同一方向に位置する。このため、検出器の向きを360°以上にわたって回転させても、検出器から引き出された配線が捩れることがなく、巻き付くこともない。   In the monitoring device according to the present invention, when the detector is rotated around the second axis by the driving device, the direction of the detector is switched. At this time, when viewed from the second axis, the detector rotates once around the first axis once during the rotation around the second axis, and in the direction opposite to the rotation around the second axis. To do. For this reason, before and after the detector rotates around the second axis, the wiring is always located in the same direction with respect to the first axis as viewed from the detector. For this reason, even if the direction of the detector is rotated over 360 ° or more, the wiring drawn from the detector is not twisted and does not wind.
以下に、図面を参照して、本発明を適用した監視装置を説明する。   A monitoring apparatus to which the present invention is applied will be described below with reference to the drawings.
(原理)
図1は、本発明を適用した監視装置の原理を示す説明図である。図1において、本発明の監視装置1は、配線83が引き出された検出器80と、この検出器80の向きを切り換える駆動装置(図示せず)とを有している。監視装置1において、駆動装置は、検出器80が向いている方向L0と平行な軸線L1と交差する方向に延びた第2の軸線L2周りの回転(θ回転)を検出器80に行わせるとともに、第2の軸線L2からみたとき、第2の軸線L2周りの回転を1回行う間に検出器80に第1の軸線L1周りの回転(ψ回転)を1回、第2の軸線L2周りの回転とは逆方向に行わせる。
(principle)
FIG. 1 is an explanatory diagram showing the principle of a monitoring apparatus to which the present invention is applied. In FIG. 1, the monitoring device 1 of the present invention includes a detector 80 from which a wiring 83 is drawn, and a drive device (not shown) for switching the direction of the detector 80. In the monitoring device 1, the drive device causes the detector 80 to rotate around the second axis L2 extending in the direction intersecting the axis L1 parallel to the direction L0 in which the detector 80 faces (θ rotation). When viewed from the second axis L2, the detector 80 rotates once around the first axis L1 (ψ rotation) once around the second axis L2 while rotating around the second axis L2 once. This is done in the opposite direction to the rotation.
すなわち、監視装置1を外部からみると、検出器80は、第2の軸線L2周りのθ回転を行う際、第1の軸線L1周りにψ回転せず、第1の軸線L1周りにおける同一の角度方向を向いたまま、第2の軸線L2周りにθ回転する。   That is, when the monitoring device 1 is viewed from the outside, the detector 80 does not rotate around the first axis L1 when performing the θ rotation around the second axis L2, and does not rotate the same around the first axis L1. While rotating in the angular direction, it rotates θ around the second axis L2.
このように構成した監視装置1において、駆動装置によって、検出器80を第2の軸線L2周りにθ回転させると、検出器80の向きL0は、例えば、実線で示した方向から点線で示す方向に切り換わる。その際、第2の軸線L2からみると、検出器80は、第2の軸線L2周りのθ回転を1回行う間に第1の軸線L1周りのψ回転を1回、第2の軸線L2周りのθ回転とは逆方向に行う。このため、検出器80が第2の軸線L2周りの回転を行う前後において、検出器80からみて配線83は常に同一方向に引き出された状態にあり、配線83は、第1の軸線L1に対して常に同一方向に位置する。このため、検出器80の向きを360°以上にわたって回転させても、検出器80から引き出された配線が捩れることがなく、巻き付くこともない。   In the monitoring apparatus 1 configured as described above, when the detector 80 is rotated by θ around the second axis L2 by the driving device, the direction L0 of the detector 80 is, for example, the direction indicated by the dotted line from the direction indicated by the solid line. Switch to. At this time, when viewed from the second axis L2, the detector 80 performs one rotation of ψ about the first axis L1 and one second rotation about the second axis L2 while performing θ rotation about the second axis L2. It is performed in the direction opposite to the surrounding θ rotation. Therefore, before and after the detector 80 rotates around the second axis L2, the wiring 83 is always drawn in the same direction as viewed from the detector 80, and the wiring 83 is connected to the first axis L1. Always in the same direction. For this reason, even if the direction of the detector 80 is rotated over 360 ° or more, the wiring drawn out from the detector 80 is not twisted and wound.
(装置の具体的構成)
図2、図3および図4はそれぞれ、本発明を適用した監視装置の側面図、底面図および断面図である。
(Specific configuration of the device)
2, 3 and 4 are a side view, a bottom view and a cross-sectional view, respectively, of a monitoring device to which the present invention is applied.
図2、図3および図4に示す監視装置1は、赤外線センサなどからなる検出器80を駆動装置2によって360°以上の範囲にわたって回転させることにより、検出器80の向きを監視対象となる空間の隅々まで向かせるための装置であり、配線83が側方に引き出された検出器80と、この検出器80を内側に保持するホルダ81と、駆動装置2とを有している。   The monitoring device 1 shown in FIGS. 2, 3, and 4 rotates the detector 80 made of an infrared sensor or the like over a range of 360 ° or more by the driving device 2, thereby changing the direction of the detector 80 to be monitored. And includes a detector 80 from which the wiring 83 is pulled out to the side, a holder 81 for holding the detector 80 inside, and the driving device 2.
本形態において、ホルダ81の側面には、コネクタ82が固定されており、このコネクタ82を用いて検出器80には配線83が接続されている。ホルダ81の下面は開放状態にあり、検出器80は、下面開口から下方に向けて露出した状態にある。検出器80は、ホルダ81の中心からずれた位置に配置され、図4には、検出器80の向いている方向を矢印L0で示してある。   In this embodiment, a connector 82 is fixed to the side surface of the holder 81, and a wiring 83 is connected to the detector 80 using this connector 82. The lower surface of the holder 81 is in an open state, and the detector 80 is exposed downward from the lower surface opening. The detector 80 is disposed at a position shifted from the center of the holder 81, and the direction in which the detector 80 faces is indicated by an arrow L0 in FIG.
本形態において、駆動装置2は、ホルダ81を介して検出器80を下端部に保持した軸体10と、出力軸220が下方に延びたステッピングモータ22と、ステッピングモータ22の出力軸220に連結された円板状の伝達部材24とを備えている。ここで、軸体10は、検出器80が向いている方向L0と略平行な第1の軸線L1に延びている。また、ステッピングモータ22の出力軸220は、第1の軸線L1と交差する方向に延びた第2の軸線L2上に位置している。ステッピングモータ22は、モータ本体が固定具60などを介して天井に固定されている。ステッピングモータ22のモータ本体の下面には連結板26が固定され、この連結板26の端部の折り曲げ部分には、支持板28の上端部分が固定されている。支持板28は、伝達部材24の側方から軸体10の下端部に向けて下方に折れ曲がり、第2の軸線L2が通っている部分を横切っている。   In this embodiment, the driving device 2 is connected to the shaft body 10 holding the detector 80 at the lower end portion via the holder 81, the stepping motor 22 with the output shaft 220 extending downward, and the output shaft 220 of the stepping motor 22. The disc-shaped transmission member 24 is provided. Here, the shaft body 10 extends in a first axis L1 substantially parallel to the direction L0 in which the detector 80 faces. Further, the output shaft 220 of the stepping motor 22 is located on the second axis L2 extending in the direction intersecting the first axis L1. As for the stepping motor 22, the motor main body is being fixed to the ceiling via the fixing tool 60 grade | etc.,. The connecting plate 26 is fixed to the lower surface of the motor body of the stepping motor 22, and the upper end portion of the support plate 28 is fixed to the bent portion of the end portion of the connecting plate 26. The support plate 28 is bent downward from the side of the transmission member 24 toward the lower end portion of the shaft body 10 and crosses the portion through which the second axis L2 passes.
本形態の駆動装置2において、伝達部材24は、ステッピングモータ22の回転出力を軸体10に伝達して、軸体10および検出器80に第2の軸線L2周りの公転(θ回転)を行わせるための部材であり、第2の軸線L2から半径方向で離間した位置において、連結機構30を介して軸体10の上端部と連結されている。連結機構30は、軸体10の第2の軸線L2周りの公転、および軸体10の第1の軸線L1周りの自転(ψ回転)を許容した状態で軸体10の上端部を支持している。このような連結機構30として、本形態では、軸体10の上端部に形成された連結機構用球部31と、伝達部材24の側に形成されて連結機構用球部31が嵌る半球状の連結機構用受け部32とが用いられている。   In the driving device 2 of the present embodiment, the transmission member 24 transmits the rotation output of the stepping motor 22 to the shaft body 10, and performs the revolution (θ rotation) around the second axis L2 on the shaft body 10 and the detector 80. And is coupled to the upper end portion of the shaft body 10 via the coupling mechanism 30 at a position spaced apart from the second axis L2 in the radial direction. The coupling mechanism 30 supports the upper end portion of the shaft body 10 while allowing the revolution of the shaft body 10 around the second axis L2 and the rotation (φ rotation) around the first axis L1 of the shaft body 10. Yes. As such a coupling mechanism 30, in this embodiment, a coupling mechanism ball 31 formed on the upper end portion of the shaft body 10 and a hemispherical shape formed on the transmission member 24 side and into which the coupling mechanism ball 31 is fitted. A connection mechanism receiving portion 32 is used.
また、本形態の駆動装置2において、軸体10の下端部と支持板28との間には、第2の軸線L2と軸体10との交差部分で、軸体10の第2の軸線L2周りの公転、および軸体10の第1の軸線L1周りの自転を許容する状態で軸体10を支持する軸受機構40が構成されている。このような軸受機構40として、本形態では、軸体10の下端部に形成された軸受機構用球部41と、支持板28の側に形成されて軸受機構用球部41が嵌るリング状の軸受機構用受け部42とが用いられている。ここで、軸受機構用受け部42の底部には穴421が形成されているが、穴421は、軸受機構用球部41よりも小さいので、軸受機構用受け部42は、軸体10の下方への抜け止め機能も担っている。一方、連結機構30は、軸体10の上方へのずれを防止しており、本形態において、軸体10は、連結機構30と軸受機構40により上下方向の動きが規制されている。なお、軸体10とホルダ81との連結は穴421を介して行われている。   In the driving device 2 of the present embodiment, the second axis L2 of the shaft body 10 is located between the lower end portion of the shaft body 10 and the support plate 28 at the intersection of the second axis L2 and the shaft body 10. A bearing mechanism 40 that supports the shaft body 10 is configured in a state in which the surrounding revolution and the rotation around the first axis L1 of the shaft body 10 are allowed. As such a bearing mechanism 40, in this embodiment, a ring-shaped bearing mechanism ball 41 formed on the lower end of the shaft body 10 and a ring-shaped bearing mechanism ball 41 formed on the support plate 28 side are fitted. A bearing mechanism receiving portion 42 is used. Here, a hole 421 is formed in the bottom portion of the bearing mechanism receiving portion 42, but since the hole 421 is smaller than the bearing mechanism ball portion 41, the bearing mechanism receiving portion 42 is located below the shaft body 10. It also has a function to prevent it from falling off. On the other hand, the coupling mechanism 30 prevents the shaft body 10 from being displaced upward. In this embodiment, the shaft body 10 is restricted from moving up and down by the coupling mechanism 30 and the bearing mechanism 40. The shaft body 10 and the holder 81 are connected through a hole 421.
(本形態の動作、効果)
図4は、本発明を適用した監視装置において、検出器の向きが変化する様子を示す説明図である。本形態の監視装置1において、ステッピングモータ22を動作させると、ステッピングモータ22の出力軸220の回転が伝達部材24を介して軸体10の上端部に伝達され、図4に示すように、軸体10は、第2の軸線L2周りにすりこぎ運動を行いながら公転(θ回転)する。その結果、軸体10の姿勢が切り換わり、それに伴って検出器80の姿勢が切り換わるため、検出器80が向いている方向L0が切り換わる。それ故、軸体10に360°の公転を行わせれば、検出器80が向いている方向L0も360°回転する。また、検出器80をいずれの方向に向かせたい場合でも、180°以下の角度範囲で軸体10を公転させればよいので、所定の方向に短時間で向かせることができる。
(Operation and effect of this form)
FIG. 4 is an explanatory diagram showing how the direction of the detector changes in the monitoring apparatus to which the present invention is applied. In the monitoring device 1 of this embodiment, when the stepping motor 22 is operated, the rotation of the output shaft 220 of the stepping motor 22 is transmitted to the upper end portion of the shaft body 10 via the transmission member 24, and as shown in FIG. The body 10 revolves (rotates θ) while performing a rub motion around the second axis L2. As a result, the attitude of the shaft body 10 is switched, and accordingly the attitude of the detector 80 is switched, so that the direction L0 in which the detector 80 faces is switched. Therefore, if the shaft body 10 is revolved 360 °, the direction L0 in which the detector 80 faces also rotates 360 °. Moreover, since it is only necessary to revolve the shaft body 10 in an angle range of 180 ° or less, it is possible to make the detector 80 face in a predetermined direction in a short time, regardless of which direction the detector 80 is desired to face.
その際、連結機構30および軸受機構40では、軸体10の第2の軸線L2周りの公転、および軸体10の第1の軸線L1周りの自転の双方が可能であるため、軸体10が第2の軸線L2周りに1公転動作を行う際、第2の軸線L2からみたとき、軸体10は、第1の軸線L1周りの自転を1回、公転とは反対方向に行う。この様子を監視装置1の外部からみると、検出器80は、第2の軸線L2周りの公転を行う際、第1の軸線L1周りに自転せず、第1の軸線L1周りにおける同一の角度方向を向いたまま、第2の軸線L2周りに公転する。それ故、公転により軸体10の姿勢が切り換わるに伴って検出器80の向きが切り換わるが、検出器80に接続されている配線83は、多少振れることがあっても捩れることがなく、また、軸体10に巻き付くこともない。   At that time, in the coupling mechanism 30 and the bearing mechanism 40, both the revolution around the second axis L2 of the shaft body 10 and the rotation around the first axis L1 of the shaft body 10 are possible. When performing one revolution operation around the second axis L2, when viewed from the second axis L2, the shaft body 10 performs one revolution around the first axis L1 in the opposite direction to the revolution. When this state is viewed from the outside of the monitoring device 1, the detector 80 does not rotate around the first axis L1 when performing the revolution around the second axis L2, but the same angle around the first axis L1. Revolving around the second axis L2 while facing the direction. Therefore, although the orientation of the detector 80 is switched as the posture of the shaft body 10 is switched due to revolution, the wiring 83 connected to the detector 80 is not twisted even if it is slightly swung. Moreover, it does not wind around the shaft body 10.
また、本形態では、軸体10とともに検出器80が第2の軸線L2周りに回転するが、検出器80は、軸体10に対して常に同一方向に位置する。このため、検出器80の法線方向の向きを360°回転させても、検出器80上における座標系は公転前後で変化しないので、検出結果の解析が容易である。   Further, in this embodiment, the detector 80 rotates around the second axis L2 together with the shaft body 10, but the detector 80 is always located in the same direction with respect to the shaft body 10. For this reason, even if the direction of the normal direction of the detector 80 is rotated 360 °, the coordinate system on the detector 80 does not change before and after the revolution, so that the analysis of the detection result is easy.
さらに、本形態では、軸受機構40での自由回転により、軸体10の公転により軸体10に自動的に自転を行わせる構成を採用したため、軸体10の1公転動作中に軸体10を当該軸体10の軸線L1周りに自転させるための駆動系が不要である。それ故、監視装置1を小型かつ安価に構成することができる。   Furthermore, in this embodiment, since the shaft body 10 is automatically rotated by the revolution of the shaft body 10 by free rotation in the bearing mechanism 40, the shaft body 10 is moved during one revolution operation of the shaft body 10. A drive system for rotating around the axis L1 of the shaft body 10 is not necessary. Therefore, the monitoring device 1 can be configured small and inexpensively.
また、ステッピングモータ22の出力軸は第2の軸線L2上に位置し、かつ、軸受機構40は、第2の軸線L2と軸体10との交差部分に構成されている。このため、監視装置1を小型に構成することができる。   Further, the output shaft of the stepping motor 22 is located on the second axis L2, and the bearing mechanism 40 is configured at the intersection of the second axis L2 and the shaft body 10. For this reason, the monitoring apparatus 1 can be comprised small.
また、連結機構30は軸体10の上端側に構成され、検出器80は軸体10の下端側に連結され、軸受機構40は連結機構30と検出器80との間の位置に配置されているため、ステッピングモータ22は、小さな力で軸体10を公転させることができる。それ故、ステッピングモータ22として、小型で安価なものを用いればよい。   The coupling mechanism 30 is configured on the upper end side of the shaft body 10, the detector 80 is coupled to the lower end side of the shaft body 10, and the bearing mechanism 40 is disposed at a position between the coupling mechanism 30 and the detector 80. Therefore, the stepping motor 22 can revolve the shaft body 10 with a small force. Therefore, a small and inexpensive one may be used as the stepping motor 22.
(その他の実施形態)
上記実施の形態では、検出器80が向いている方向L0と軸体10の軸線である第1の軸線L1とが平行な構造を採用したが、検出器80が向いている方向L0と第1の軸線L1とが一致する構造、あるいは、検出器80が向いている方向L0と軸体10の軸線である第1の軸線L1とが所定の角度を成す構造を採用してもよい。また、上記実施の形態では、検出器80として赤外線センサを用いたが、検出器80として撮像装置などを用いてもよい。また、上記実施の形態では、駆動装置2の駆動源としてステッピングモータ22を用いたが、その他のDCモータ、あるいはACモータを用いてもよい。また、駆動装置2の駆動源としては、モータに代えて、手動で行ってもよい。また、上記実施の形態において、軸体10は、連結機構30と軸受機構40により上下方向の動きが規制されていたが、連結機構30および軸受機構40の一方で軸体10の上下方向の動きを規制してもよい。さらに、上記実施の形態では、軸受機構40での自由回転により、軸体10の公転により軸体10に自動的に自転を行わせる構成であったが、軸体10の公転に同期させて、軸体10を強制的に自転させる構成を採用してもよい。

Or a structure in which the direction L0 in which the detector 80 faces and the first axis L1 that is the axis of the shaft body 10 form a predetermined angle may be employed. In the above embodiment, an infrared sensor is used as the detector 80, but an imaging device or the like may be used as the detector 80. In the above embodiment, the stepping motor 22 is used as the drive source of the drive device 2, but other DC motors or AC motors may be used. Further, the drive source of the drive device 2 may be manually performed instead of the motor. Further, in the above-described embodiment, the vertical movement of the shaft body 10 is restricted by the coupling mechanism 30 and the bearing mechanism 40, but the vertical movement of the shaft body 10 is one of the coupling mechanism 30 and the bearing mechanism 40. May be regulated. Furthermore, in the said embodiment, although it was the structure which makes the shaft body 10 autorotate by the revolution of the shaft body 10 by the free rotation in the bearing mechanism 40, it synchronizes with the revolution of the shaft body 10, A configuration in which the shaft body 10 is forced to rotate may be employed.
