である。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tilt angle detection sensor for detecting that a device has tilted at a predetermined angle.

検出センサが使用されている。2. Description of the Related Art Conventionally, an inclination angle detection sensor has been used for detecting that various devices are inclined by a predetermined angle or more from a normal posture.

は、例えば以下のような構造のものがあった。[0003] As a conventional inclination angle detection sensor, for example, there is one having the following structure.

の。A light-emitting element and a light-receiving element are installed in a case so as to face each other, and a light-shielding body that blocks the light-emitting element is suspended from the ceiling of the case. A structure in which the light-receiving element receives light from the light-emitting element by moving and detects that the case is tilted.

る構造のもの。When the reflector is suspended in the case and the case is horizontal, the light emitted from the light emitting element installed in the case is made to enter the light receiving element after being reflected by the reflector, and the case is inclined. In this case, the structure is such that the position of the reflecting mirror in the case relatively moves, so that light reflected by the reflecting mirror does not enter the light receiving element and the case is tilted.

の。[0006] The sphere is housed in a mortar-shaped case having a bottom surface. When the case is in a normal posture, the sphere moves to the deepest part of the mortar, and when the case is tilted, the sphere leaves the position. Use to detect case tilt.

りしてしまうためその検出が不可能であった。In any of the prior arts, since the light shielding body, the reflecting mirror and the sphere suspended in the case freely move in the direction of gravity in the case, for example, when the inclination angle to be detected exceeds 90 °. However, since the light-shielding body, the reflecting mirror, or the sphere hits the case, or the thread hanging on the light-shielding body or the reflecting mirror sags, it is impossible to detect such a case.

う。In any of the prior arts, the light shielding body, the reflecting mirror, and the sphere suspended in the case move freely in the direction of gravity in the case, so that the case is at an angle close to 180 ° (ie, upside down).
In the case where the case is inclined, the light-shielding body, the reflecting mirror, or the sphere hits the ceiling surface of the case, so that sound or vibration is generated.

Another object of the present invention is to provide a tilt angle detection sensor which can easily cope with a case where the tilt angle to be detected is different between the front direction and the rear direction.

And the state excluding the flexible substrate 40 (however, the photo interrupter 45 is described).

It is engaged only near the upper end a and near the lower end b, and a space c is provided therebetween.
【0024】これは軸部21と回転支持軸13の摺接面

(E) and (f) show 65 °, 90 °, 18
It shows a case where the camera is rotated and tilted by 0 °, 190 °, and 270 °.

トインタラプタ45はオフである。As shown in FIG. 2A, when the inclination angle detecting sensor is in the normal posture (this is the same as the posture shown in FIG. 2), the reflecting portion 25 is not located in front of the photo-interrupter 45. Therefore, the light emitted from the light emitting unit 451 is not reflected and does not enter the light receiving unit 453. Therefore, the photo interrupter 45 is off.

入射され、フォトインタラプタ45はオンとなる。Next, as shown in FIG. 2B, if the inclination angle detection sensor is rotated and inclined forward (to the left), the weight 30 attached to the rotating member 20 moves vertically downward due to gravity. When rotated relative to case 10 and as a result tilted to 65 °, photointerrupter 45
The light emitted from the light emitting unit 451 is reflected by the reflecting surface 27 and is incident on the light receiving unit 453, and the photo interrupter 45 is turned on.

タラプタ45の面前に反射部25が位置しているので、
フォトインタラプタ45はオン状態を持続する。Further, as shown in FIGS. 3 (c), 3 (d) and 3 (e), the inclination angle detecting sensor is moved forward by 90 ° → 180 °.
Even if it is rotated by 190 °, since the reflection part 25 is always located in front of the photointerrupter 45 during that time,
The photo interrupter 45 remains on.

タラプタ45はオフとなる。The rotation angle of the inclination angle detection sensor is 1
When the angle exceeds 90 °, the reflecting portion 25 disappears from the front of the photo-interrupter 45, and the light-emitting portion 453 cannot receive the light emitted from the light-emitting portion 451, so that the photo-interrupter 45 is turned off.

The photointerrupter 45 is turned off in the range of ° to 65 ° and 190 ° to 360 °, and turned on in the range of 65 ° to 190 °. According to this inclination angle detection sensor, 3
An inclination angle in the entire range of 60 ° can be detected.

の種々の光センサを用いることもできる。Although one embodiment of the present invention has been described in detail, the present invention is not limited to the above-described embodiment, and for example, the following various modifications are possible. In the above embodiment, the photo interrupter 45 is used as the optical sensor. Instead, for example, a light emitting element and a light receiving element are provided on both sides of the rotating surface of the reflecting portion 25 of the rotating member 20, respectively. When there is the reflection unit 25, other various optical sensors may be used, such as a configuration in which the light receiving element cannot receive light.
【0032】反射部25の形状を種々変更すること

い。なお反射部25は回転部材20に複数箇所設けても
良く、一方光センサも複数個設けても良く、このように
構成すれば多数の傾斜角度の検出ができる。It is needless to say that various inclination angles can be detected by variously changing the shape of the reflecting portion 25. The reflecting section 25 may be provided at a plurality of positions on the rotating member 20, while a plurality of optical sensors may be provided. With such a configuration, a large number of inclination angles can be detected.
【0033】回転部材20は必ずしもケース10で覆

い。The rotating member 20 does not necessarily need to be covered with the case 10; in other words, another mounting member may be used as long as the rotating member 20 can be rotatably mounted.
【0034】回転部材20自体の重さで回転できるよ
うな場合は、錘30は必ずしも必要ない。If the rotating member 20 can be rotated by its own weight, the weight 30 is not always necessary.

〜360°の内のどのような角度であってもこれに容易
且つ正確に対応できる。As described in detail above, the present invention has the following excellent effects. Since the position of the rotatably mounted rotating member is detected by the optical sensor, the inclination angle to be detected is zero.
Any angle of ~ 360 ° can be easily and accurately accommodated.

容易に対応できる。Further, even when the inclination angle to be measured is different between the front direction and the rear direction, this can be easily coped with. Further, even when there are a large number of inclination angles to be measured, this can be easily coped with simply by increasing the number of optical sensors or changing the number or shape of the reflecting portions.
【0037】従来のように遮光体をケース内に吊り下

な場合でも音や振動の発生する恐れがない。Since there is no structure in which the light shield is suspended in the case as in the prior art, there is no danger of generating sound or vibration even when the light shield is turned upside down.
