本物品は、「構成部位の名称を示す参考図１」及び「構成部位の名称を示す参考図２」に示すように、上円板と、下円板と、上下２つの円板の間に配置される円筒部とで構成される非接触静電フィルム付センサーである。円筒部は、「構成部位の名称を示す参考図１」及び「構成部位の名称を示す参考図２」に示すように、光を透過することができる透光性領域と、光を遮ることができる遮光性領域とを有している。また、円筒部の内部には、円筒の全周にわたって１枚又は複数枚の静電フィルムが巻き付けられている。本物品の非接触静電フィルム付センサーは、静電フィルムが検知した信号を、制御信号へ変換し、非接触静電フィルム付センサー内部に収納設置される１個又は複数個のＬＥＤに送信することで、ＬＥＤの点灯、ＬＥＤの消灯、ＬＥＤの発光色変更及びＬＥＤの光量調節を行うことができる。さらに、下円板の背面側には、電源又は信号等の受送信を行うためのケーブルを接続するための接続口（例えば、ＵＳＢ差込口）が設けられている。本物品では、静電フィルムが巻き付けられた円筒部の近傍で使用者が例えば手のジェスチャー操作を行うと、静電フィルムがジェスチャー操作を行う使用者の手の状態を非接触状態で検知することができる。非接触静電フィルム付センサーは、静電フィルムが検知した情報に基づく信号を、制御信号へ変換し、ＬＥＤに送信することで、ＬＥＤに対して様々な動作を実行させることができる。例えば、ＬＥＤが消灯した状態で使用者が手を円筒部の近傍で一方向に移動させた場合にはＬＥＤが点灯し、ＬＥＤが点灯した状態で使用者が再び手を円筒部の近傍で一方向に移動させた場合にはＬＥＤが消灯する動作を実行させてもよい。また例えば、ＬＥＤが消灯した状態で使用者が手を円筒部に近づけて一定の距離を維持したまま手の位置を固定させた場合には、ＬＥＤが点灯した後、所定時間の経過とともにＬＥＤの発光色を変化させることで円筒部の透光性領域が様々な色に発光し、最終的にＬＥＤが消灯するといった動作を実行させてもよい。また例えば、使用者が円筒部の近傍で手のジェスチャー操作を行った場合に、静電フィルムが使用者の手の位置や円筒部に対する距離を検知し、検知した情報を外部に信号として送信することで、本物品と接続した外部機器（例えば、コンピュータやマイコン等の電子計算機）の動作制御を実行することができる。なお、「使用状態を示す参考図１」乃至「使用状態を示す参考図３」において例示する円筒部の発光色は、「赤色」、「青色」、「オレンジ色」の３色が示されているが、本物品に係る非接触静電フィルム付センサーでは、あらゆる種類の発光色を採用することができ、また、円筒部の透光性領域を複数の発光色で同時に発光させることもできる。なお、静電フィルムは、円筒部の外周にわたって１枚又は複数枚を巻き付けることもできる。This article is arranged between the upper disk, the lower disk, and the upper and lower disks as shown in "Reference Figure 1 showing the names of the constituent parts" and "Reference Figure 2 showing the names of the constituent parts". It is a sensor with a non-contact electrostatic film composed of a cylindrical part. As shown in "Reference Figure 1 showing the names of the constituent parts" and "Reference Figure 2 showing the names of the constituent parts", the cylindrical portion has a translucent region capable of transmitting light and can block light. It has a light-shielding area that can be formed. Further, one or a plurality of electrostatic films are wound around the entire circumference of the cylinder portion inside the cylinder portion. The sensor with non-contact electrostatic film of this article converts the signal detected by the electrostatic film into a control signal and transmits it to one or more LEDs housed and installed inside the sensor with non-contact electrostatic film. This makes it possible to turn on the LED, turn off the LED, change the emission color of the LED, and adjust the amount of light of the LED. Further, on the back side of the lower disk, a connection port (for example, a USB insertion port) for connecting a cable for transmitting and receiving a power supply or a signal or the like is provided. In this article, when the user performs, for example, a hand gesture operation in the vicinity of the cylindrical portion around which the electrostatic film is wound, the electrostatic film detects the state of the user's hand performing the gesture operation in a non-contact state. Can be done. The sensor with a non-contact electrostatic film converts a signal based on the information detected by the electrostatic film into a control signal and transmits it to the LED, so that the LED can perform various operations. For example, when the user moves his / her hand in one direction near the cylinder while the LED is off, the LED turns on, and when the LED is on, the user again moves his / her hand near the cylinder. When the LED is moved in the direction, the operation of turning off the LED may be executed. Further, for example, when the user puts his / her hand close to the cylindrical portion and fixes the position of the hand while maintaining a certain distance while the LED is turned off, the LED is turned on and then the LED is turned on with the lapse of a predetermined time. By changing the emission color, the translucent region of the cylindrical portion may emit light in various colors, and finally the LED may be turned off. Further, for example, when the user performs a hand gesture operation in the vicinity of the cylindrical portion, the electrostatic film detects the position of the user's hand and the distance to the cylindrical portion, and transmits the detected information as a signal to the outside. This makes it possible to control the operation of an external device (for example, a computer such as a computer or a microcomputer) connected to the article. The emission colors of the cylindrical portion exemplified in "Reference Figure 1 showing the usage state" to "Reference Figure 3 showing the usage state" are shown in three colors of "red", "blue", and "orange". However, in the sensor with a non-contact electrostatic film according to this article, all kinds of emission colors can be adopted, and the translucent region of the cylindrical portion can be emitted with a plurality of emission colors at the same time. In addition, one or a plurality of electrostatic films may be wound around the outer circumference of the cylindrical portion.
