　続いて、図５から図８を用いて、実施の形態１に係る盗撮防止装置の動作を説明する。
　図５および図６は、実施の形態１に係る盗撮防止装置の要部の上面図である。図７は、実施の形態１に係る盗撮防止装置を備えたエレベーターのかごの上面図である。図８は、実施の形態１に係る盗撮防止装置を備えたエレベーターのかごの鉛直断面図である。 Subsequently, the operation of the voyeurism prevention device according to the first embodiment will be described with reference to FIGS.
5 and 6 are top views of the main part of the voyeurism prevention device according to the first embodiment. FIG. 7 is a top view of an elevator car provided with the anti-voyeurism device according to the first embodiment. FIG. 8 is a vertical sectional view of an elevator car provided with the voyeurism prevention device according to the first embodiment.
　図５において、一対のかご扉９が開いている状態が示される。紙面左方向は、右かご扉９ｒの戸閉方向である。紙面上方向は、かご５の前方向である。 FIG. 5 shows a state where the pair of car doors 9 are open. The left direction in the drawing is the door closing direction of the right car door 9r. The upward direction in the drawing is the forward direction of the car 5.
　投光部１２は、上下方向の複数の箇所から戸閉方向の側に赤外線１６を出力する。投光部１２は、時間的にランダムまたは擬似ランダムなパルスとして赤外線１６を出力する。 The light projecting unit 12 outputs infrared rays 16 from a plurality of locations in the vertical direction to the door closing direction. The light projecting unit 12 outputs the infrared rays 16 as temporally random or pseudo-random pulses.
　反射板１９は、回転軸２０のねじりバネによって、右かご扉９ｒの戸閉方向と平行になる向きに向けられる。このとき、反射板１９は、投光部１２が出力する赤外線１６を受けない。赤外線１６は、戸閉方向の側に進行する。すなわち、反射板１９は、赤外線１６をかご５の内側に誘導しない。 The reflecting plate 19 is directed by the torsion spring of the rotating shaft 20 in a direction parallel to the door closing direction of the right car door 9r. At this time, the reflecting plate 19 does not receive the infrared rays 16 output from the light projecting unit 12. The infrared rays 16 travel to the door closing direction side. That is, the reflecting plate 19 does not guide the infrared rays 16 to the inside of the car 5.
　図５に図示されない受光部１３は、赤外線１６を受光する。受光部１３は、赤外線１６の受光の状態によって投光部１２との間の物体の有無を検知する。投光部１２が出力する赤外線１６が遮られずに受光される場合に、受光部１３は、投光部１２との間に物体がないことを検知する。一方、投光部１２が出力する赤外線１６の少なくとも一部が遮られる場合に、受光部１３は、投光部１２との間に物体があることを検知する。このとき、一対のかご扉９は、開いている状態を維持する。なお、一対のかご扉９が閉じる動作を行っているときに受光部１３が投光部１２との間に物体があることを検知した場合に、一対のかご扉９は、開く動作を行う。 The light receiving unit 13 (not shown in FIG. 5) receives the infrared rays 16. The light receiving unit 13 detects the presence of an object between the light projecting unit 12 and the light receiving state of the infrared rays 16. When the infrared rays 16 output from the light projecting unit 12 are received without being blocked, the light receiving unit 13 detects that there is no object between the light projecting unit 12 and the light projecting unit 12. On the other hand, when at least a part of the infrared ray 16 output from the light projecting unit 12 is blocked, the light receiving unit 13 detects that there is an object between the light projecting unit 12. At this time, the pair of car doors 9 maintains an open state. In addition, when the light receiving unit 13 detects that there is an object between the light projecting unit 12 and the pair of car doors 9 are being closed, the pair of car doors 9 is opened.
　図６において、一対のかご扉９が閉じている状態が示される。紙面左方向は、右かご扉９ｒの戸閉方向である。紙面上方向は、かご５の前方向である。 FIG. 6 shows a state in which the pair of car doors 9 are closed. The left direction in the drawing is the door closing direction of the right car door 9r. The upward direction in the drawing is the forward direction of the car 5.
　一対のかご扉９が閉じる動作を行うときに、図６に図示されない受光部１３は、左かご扉９ｌとともに左かご扉９ｌの戸閉方向に動く。このとき、投光部１２および誘導部１５は、右かご扉９ｒとともに右かご扉９ｒの戸閉方向に動く。一対のかご扉９が閉じるときに、接触板１８は、受光部１３に接触する。受光部１３は、接触板１８を押して回転軸２０のねじりバネの弾性力に抗しながら反射板１９を回転させる。反射板１９は、回転によって投光部１２が出力する赤外線１６を受ける位置に移動する。 When the pair of car doors 9 is closed, the light receiving unit 13 (not shown in FIG. 6) moves in the door closing direction of the left car door 9l together with the left car door 9l. At this time, the light projecting unit 12 and the guiding unit 15 move in the door closing direction of the right car door 9r together with the right car door 9r. When the pair of car doors 9 are closed, the contact plate 18 contacts the light receiving unit 13. The light receiving unit 13 rotates the reflecting plate 19 while pressing the contact plate 18 against the elastic force of the torsion spring of the rotating shaft 20. The reflecting plate 19 moves to a position for receiving the infrared rays 16 output from the light projecting unit 12 by rotation.
　投光部１２は、一対のかご扉９が開いている場合と同様に、戸閉方向の側に赤外線１６を出力する。赤外線１６は、反射板１９によってかご５の内側に向けて反射する。赤外線１６の反射光２１は、反射板１９によって拡散される。 The light projecting unit 12 outputs infrared rays 16 to the door closing side as in the case where the pair of car doors 9 are open. The infrared rays 16 are reflected toward the inside of the car 5 by the reflecting plate 19. The reflected light 21 of the infrared 16 is diffused by the reflecting plate 19.
　図７において、一対のかご扉９が閉じている状態が示される。紙面上方向は、かご５の前方向である。紙面左方向は、かご５の左方向である。紙面右方向は、かご５の右方向である。 FIG. 7 shows a state where the pair of car doors 9 are closed. The upward direction in the drawing is the forward direction of the car 5. The left direction in the drawing is the left direction of the car 5. The right direction on the page is the right direction of the car 5.
　反射光２１は、透過板１１を透過してかご５の内側に誘導される。反射光２１は、かご５の壁面に設けられる反射部１４によって反射される。 The reflected light 21 passes through the transmission plate 11 and is guided inside the car 5. The reflected light 21 is reflected by the reflecting portion 14 provided on the wall surface of the car 5.
　図８において、一対のかご扉９が閉じている状態が示される。紙面下方向は、かご５の下方向である。 FIG. 8 shows a state where the pair of car doors 9 are closed. The downward direction of the paper is the downward direction of the car 5.
　反射光２１は、反射板１９によって下方を含む方向に向けて拡散される。反射光２１は、かご５の床面に設けられる反射部１４によって反射される。 The reflected light 21 is diffused by the reflector 19 in a direction including the lower part. The reflected light 21 is reflected by the reflecting portion 14 provided on the floor surface of the car 5.
　以上に説明したように、実施の形態１に係る盗撮防止装置１０は、投光部１２と、誘導部１５と、を備える。投光部１２は、エレベーター１の右かご扉９ｒの戸閉方向の側の端部に設けられる。投光部１２は、戸閉方向の側にパルスとして赤外線１６を出力する。誘導部１５は、投光部１２より戸閉方向の側に設けられる。誘導部１５は、一対のかご扉９が閉じているときに赤外線１６を一対のかご扉９が設けられるかご５の内側に誘導する。このため、投光部１２は、かごの内側の空間に設けられる必要がない。エレベーター１において、乗客は、混雑時などにかご５の内側の空間に密集して乗車しうる。このため、かご５の内側の空間において、機器を設置する位置などの条件に制約がある。一方、実施の形態１に係る盗撮防止装置１０は、当該制約を考慮する必要がない。 As described above, the voyeurism prevention device 10 according to Embodiment 1 includes the light projecting unit 12 and the guiding unit 15. The light projecting unit 12 is provided at the end of the right car door 9r of the elevator 1 on the side in the door closing direction. The light projecting unit 12 outputs infrared rays 16 as pulses to the door closing direction side. The guiding portion 15 is provided on the door closing direction side from the light projecting portion 12. The guiding portion 15 guides the infrared rays 16 to the inside of the car 5 where the pair of car doors 9 are provided when the pair of car doors 9 are closed. For this reason, the light projection part 12 does not need to be provided in the space inside a cage | basket | car. In the elevator 1, passengers can get in the space inside the car 5 when crowded. For this reason, in the space inside the car 5, there are restrictions on the conditions such as the position where the device is installed. On the other hand, the voyeurism prevention device 10 according to Embodiment 1 does not need to consider the restriction.
　投光部１２は、パルスとして赤外線１６を出力することで、盗撮される画像にノイズを発生させる。投光部は、ノイズを発生させて画像の品質を劣化させることで、盗撮された画像の二次流出を防止できる。また、盗撮者の盗撮行為に対する意欲を減退させることで、盗撮が行われることが抑止される。ここで、撮影機器は、赤外線に感度を持つ。赤外線は不可視光であるため、乗客に視認されない。このため、乗客にパルスが視認されることで不快感を与えない。 The light projecting unit 12 generates noise in the voyeurized image by outputting infrared 16 as a pulse. The light projecting unit can prevent secondary outflow of a voyeurized image by generating noise and degrading the quality of the image. Further, by reducing the eagerness of a voyeur to voyeurism, voyeurism is prevented from being performed. Here, the photographing device is sensitive to infrared rays. Since infrared rays are invisible light, they are not visually recognized by passengers. For this reason, the passenger does not feel uncomfortable by seeing the pulse.
　赤外線１６は、右かご扉９ｒの端部からかご５の内部に誘導される。一対のかご扉９の付近において、他の乗客の出入が多いため、乗客は立ち止まりにくい。このため、赤外線１６の反射光２１が乗客によって遮蔽されにくい。 The infrared rays 16 are guided into the car 5 from the end of the right car door 9r. In the vicinity of the pair of car doors 9, since there are many other passengers coming and going, it is difficult for the passengers to stop. For this reason, the reflected light 21 of the infrared rays 16 is not easily shielded by passengers.
　また、投光部１２は、ランダムまたは擬似ランダムなパルスとして赤外線１６を出力する。フレームレートなどの動画撮影の仕様は、撮影に用いられる機器によって異なる場合がある。このとき、盗撮防止装置１０は、撮影に用いられる機器の動画撮影の仕様によらずに、盗撮される画像にノイズを発生させることができる。 Further, the light projecting unit 12 outputs infrared rays 16 as random or pseudo-random pulses. The specifications for moving image shooting such as the frame rate may differ depending on the device used for shooting. At this time, the voyeurism prevention device 10 can generate noise in the voyeurized image regardless of the moving image shooting specification of the device used for shooting.
　また、盗撮防止装置１０は、受光部１３を備える。受光部１３は、投光部１２に対して投光部が赤外線１６を出力する側に設けられる。受光部１３は、一対のかご扉９が開いているときに赤外線１６の受光の状態によって投光部１２との間の物体の有無を検知する。誘導部１５は、一対のかご扉９が開いているときに赤外線１６をかご５の内側に誘導しない。 The voyeurism prevention device 10 includes a light receiving unit 13. The light receiving unit 13 is provided on the side where the light projecting unit 12 outputs the infrared rays 16 with respect to the light projecting unit 12. The light receiving unit 13 detects the presence or absence of an object between the light projecting unit 12 and the presence of an infrared ray 16 when the pair of car doors 9 are open. The guiding portion 15 does not guide the infrared rays 16 to the inside of the car 5 when the pair of car doors 9 are open.
　受光部１３が投光部１２との間に物体があると検知する場合に、一対のかご扉９は、閉じない。すなわち、投光部１２と受光部１３とは、マルチビームドアセンサーの装置として動作する。これにより、一対のかご扉９に物体が挟まれることが防止される。 When the light receiving unit 13 detects that there is an object between the light projecting unit 12, the pair of car doors 9 are not closed. That is, the light projecting unit 12 and the light receiving unit 13 operate as a multi-beam door sensor device. Thereby, an object is prevented from being caught between the pair of car doors 9.
　誘導部１５は、一対のかご扉９の開閉に応じて赤外線１６の誘導を切り替える。このため、物体の検知に用いる赤外線源と、盗撮の防止に用いる赤外線源と、を別個に備える必要がない。これにより、エレベーター１の構成が簡単になる。特に、例えばマルチビームドアセンサーの装置として投光部１２と受光部１３とが既にエレベーターに設けられている場合に、赤外線源を新たに設けることなく盗撮防止装置１０を構成できる。 The guidance unit 15 switches the guidance of the infrared rays 16 according to the opening and closing of the pair of car doors 9. For this reason, it is not necessary to separately provide an infrared source used for detecting an object and an infrared source used for preventing voyeurism. Thereby, the structure of the elevator 1 becomes simple. In particular, for example, when the light projecting unit 12 and the light receiving unit 13 are already provided in an elevator as a multi-beam door sensor device, the voyeurism prevention device 10 can be configured without newly providing an infrared source.
　また、誘導部１５は、赤外線１６を反射可能な反射板１９を備える。誘導部１５は、一対のかご扉９が閉じるときに受光部１３および投光部１２の間で押されることで、赤外線１６をかご５の内側に反射させる向きに反射板１９を回転させる。 Further, the guide unit 15 includes a reflector 19 that can reflect the infrared rays 16. The guiding portion 15 is pushed between the light receiving portion 13 and the light projecting portion 12 when the pair of car doors 9 are closed, thereby rotating the reflecting plate 19 in a direction in which the infrared rays 16 are reflected to the inside of the car 5.
　誘導部１５による赤外線１６の誘導は、一対のかご扉９の開閉の動作によって切り替えられる。これにより、誘導部１５は、専用の駆動部を必要としない。このため、盗撮防止装置１０の構成が簡単になる。 The guidance of the infrared rays 16 by the guidance unit 15 is switched by opening and closing the pair of car doors 9. Thereby, the induction | guidance | derivation part 15 does not require an exclusive drive part. For this reason, the configuration of the voyeurism prevention device 10 is simplified.
　また、反射板１９は、赤外線１６を反射させるときに赤外線を拡散させる。赤外線１６の反射光２１は、拡散によって広い範囲に伝播する。このため、かご５の内部の乗客などによって反射光２１が遮蔽されにくい。 Further, the reflecting plate 19 diffuses infrared rays when reflecting the infrared rays 16. The reflected light 21 of the infrared ray 16 propagates over a wide range by diffusion. For this reason, the reflected light 21 is not easily shielded by passengers or the like inside the car 5.
　また、誘導部１５は、例えば拡散によって、下方を含む方向に向けて赤外線１６を誘導する。例えば女性の乗客が着用しているスカートの中が盗撮される場合に、撮影に用いられる機器は、上方に向けられる。このとき、赤外線１６の反射光２１は、当該機器に向けて誘導される。このため、盗撮される画像に効果的にノイズを発生させることができる。 Further, the guiding unit 15 guides the infrared rays 16 in a direction including the lower side by, for example, diffusion. For example, when the inside of a skirt worn by a female passenger is voyeurized, the device used for photographing is directed upward. At this time, the reflected light 21 of the infrared rays 16 is guided toward the device. For this reason, noise can be effectively generated in a voyeurized image.
　また、盗撮防止装置１０は、反射部１４を備える。反射部１４は、かご５の内側の面の少なくとも一部に設けられる。反射部１４は、赤外線１６の反射光２１を反射可能である。 Moreover, the voyeurism prevention device 10 includes a reflection unit 14. The reflecting portion 14 is provided on at least a part of the inner surface of the car 5. The reflection unit 14 can reflect the reflected light 21 of the infrared rays 16.
　反射光２１は、反射によって広い範囲に、複数の方向から伝播する。このため、かご５の内部の乗客などによって反射光２１が遮蔽されにくい。かごの内側の空間に多数の赤外線源を設けることなく、複数の方向から赤外線を伝播させることができる。 The reflected light 21 propagates from a plurality of directions over a wide range by reflection. For this reason, the reflected light 21 is not easily shielded by passengers or the like inside the car 5. Infrared rays can be propagated from a plurality of directions without providing a large number of infrared sources in the space inside the car.
　なお、かご５の内側にディスプレイなどの情報を表示する装置がある場合に、当該装置は、盗撮防止装置１０が動作していることを表示してもよい。乗客は、盗撮行為に対して不安を抱くことなく、安心してエレベーター１を利用できる。また、盗撮者の盗撮行為に対する意欲を減退させることで、盗撮が行われることが抑止される。 In addition, when there is a device that displays information such as a display inside the car 5, the device may display that the voyeurism prevention device 10 is operating. Passengers can use the elevator 1 without worrying about voyeurism. Further, by reducing the eagerness of a voyeur to voyeurism, voyeurism is prevented from being performed.
　反射板１９は、赤外線を反射させる面を下方に傾けて設けられてもよい。このとき、誘導部１５は、下方に傾く複数の反射板を備えてもよい。 The reflection plate 19 may be provided with a surface that reflects infrared rays inclined downward. At this time, the guiding portion 15 may include a plurality of reflecting plates that are inclined downward.
　投光部１２は、左かご扉９ｌに設けられてもよい。このとき、盗撮防止装置１０が受光部１３を備える場合に、受光部１３は、右かご扉９ｒに設けられる。誘導部１５は、投光部１２より左かご扉９ｌの戸閉方向の側に設けられる。すなわち、誘導部１５は、投光部１２が赤外線を出力する側に設けられる。誘導部１５は、受光部１３に設けられてもよい。 The light projecting unit 12 may be provided in the left car door 9l. At this time, when the voyeurism prevention device 10 includes the light receiving unit 13, the light receiving unit 13 is provided in the right car door 9r. The guiding portion 15 is provided on the side of the left car door 9l in the door closing direction from the light projecting portion 12.

The cage includes a door stop. The door stop portion is a portion that is hit when the car door closes to the end of the car door in the door closing direction that slides in the door closing direction. The light projecting unit 12 is provided at the end of the car door in the door closing direction. Further, when the voyeurism prevention device 10 includes the light receiving unit 13, the light receiving unit 13 is provided in the door stop.
　なお、投光部１２は、戸当たり部に設けられてもよい。このとき、投光部１２は、かご扉の戸閉方向の反対側にパルスとして赤外線を出力する。また、盗撮防止装置１０が受光部１３を備える場合に、受光部１３は、かご扉の戸閉方向の側の端部に設けられる。誘導部１５は、投光部１２より戸閉方向の反対側に設けられる。すなわち、誘導部１５は、投光部１２が赤外線を出力する側に設けられる。誘導部１５は、投光部１２または受光部１３の少なくとも一方に設けられる。 In addition, the light projection part 12 may be provided in a door stop part. At this time, the light projecting unit 12 outputs infrared rays as pulses to the opposite side of the car door in the door closing direction.
