Description

本発明はインターホンの玄関子機に係り、特に、来訪者を撮像するカメラ部の近傍に取り付けられ、周辺の照度が低い場合に前記来訪者を照射するためのLEDからの光が、広角カメラのレンズ（カメラカバー）に入射させない構造を有するインターホンの玄関子機に関する。 The present invention relates to an intercom entrance device, and in particular, is attached in the vicinity of a camera unit that images a visitor, and light from an LED for illuminating the visitor when the ambient illuminance is low, The present invention relates to an intercom entrance device having a structure in which it is not incident on a lens (camera cover).

従来から、この種のインターホンの玄関子機として、カメラを有する玄関子機であって、来訪者を撮像するカメラの側方に配置した赤外照明用の赤外発光素子から発光された光が、カメラ前面にあるカメラカバーに反射し、カメラのレンズに入射しないようにするためのリブを設けた構造を有するものがあった（例えば、特許文献１）。 Conventionally, as an entrance cordless device of this type of interphone, an entrance cordless handset having a camera, in which light emitted from an infrared light emitting element for infrared illumination arranged on the side of the camera for imaging a visitor is received. Some have a structure in which ribs are provided so as to be reflected on the camera cover on the front of the camera and not to enter the lens of the camera (for example, Patent Document 1).

このような構造によれば、赤外発光素子から発光された光が、レンズに入射することがないので写り込みがなく、良好な映像を出画させることが可能となる。 According to such a structure, since light emitted from the infrared light emitting element does not enter the lens, there is no reflection, and a good image can be displayed.

特開昭６３−１２６３８２号公報JP 63-126382 A

しかしながら、従来例のインターホンの玄関子機において、広角カメラを用いられていない。広角カメラの場合、カメラカバーを略ドーム形状としなければならないため、同一の構造ではリブの配置及び、その構造が複雑となってしまう虞がある。そのため、発光素子（LED）は、カメラ部から離間した位置に配置する必要があり、新たに発光素子からの光がカメラカバーに入射しない構造が必要となった。 However, a wide-angle camera is not used in the conventional intercom entrance unit. In the case of a wide-angle camera, since the camera cover has to be substantially dome-shaped, the arrangement of the ribs and the structure thereof may be complicated in the same structure. Therefore, it is necessary to arrange the light emitting element (LED) at a position separated from the camera unit, and a structure in which light from the light emitting element is not incident on the camera cover is required.

本発明は、上述の難点を解消するためになされたもので、広角のカメラのカバーであってもLEDからの光が写り込むことがなく、また、来訪者の照射を確実におこなうことができるインターホンの玄関子機を提供することを目的とする。 The present invention has been made to solve the above-described problems, and even a wide-angle camera cover does not capture light from the LED, and can reliably irradiate visitors.

以下、本発明のインターホンの玄関子機を適用した好ましい形態の実施例について、図面を参照して説明する。 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of an intercom entrance device according to the present invention will be described below with reference to the drawings.

図１は、本発明のインターホンの玄関子機の斜視図である。 FIG. 1 is a perspective view of an intercom entrance device of the present invention.

図１に示すインターホンの玄関子機１は、来訪者を撮像するカメラ部（カメラ２及びカメラカバー２１）、居住者と通話するためのマイク３、スピーカ４、来訪者が居住者を呼び出す場合に操作する呼出ボタン５、呼出時に来訪者を照射する照射部（LEDブラケット６、LED６１）から構成されている。また、玄関子機１は、ケース上１１（化粧パネル１１ａ）、ケース下１２（図２（ａ）参照）を嵌合して構成している。 The intercom entrance device 1 shown in FIG. 1 has a camera unit (camera 2 and camera cover 21) for imaging a visitor, a microphone 3 for talking with a resident, a speaker 4, and a visitor calling a resident. A call button 5 to be operated and an irradiation unit (LED bracket 6 and LED 61) for irradiating a visitor at the time of the call are configured. Further, the entrance cordless handset 1 is configured by fitting an upper case 11 (decorative panel 11a) and a lower case 12 (see FIG. 2A).

図２（ａ）は、玄関子機の断面図である。図２（ｂ）は図２（ａ）の部分拡大図である。図２（ａ）、（ｂ）に示すように、カメラ２をカバーするカメラカバー２１は略ドーム形状となっており、ケース上１１（化粧パネル１１ａ）よりも前面に突出している。 Fig.2 (a) is sectional drawing of an entrance child machine. FIG. 2B is a partially enlarged view of FIG. As shown in FIGS. 2A and 2B, the camera cover 21 that covers the camera 2 has a substantially dome shape, and protrudes to the front side from the case top 11 (the decorative panel 11a).

図２（ｃ）は、図２（ｂ）の一部をさらに拡大した図である。図２（ｂ）（ｃ）に示すように、LED６１の前面にあるLEDブラケット６は、ケース上１１（化粧パネル１１ａ）よりも下部に配置され、具体的にはケース上１１（化粧パネル１１ａ）からHの深さを有している。当該深さＨは、カメラカバー２１とLEDブラケット６の収容部の壁面のうちカメラ部側の壁面S1の頂点を結ぶ接線L1に接触しない位置となる深さとしている。 FIG. 2C is a further enlarged view of part of FIG. As shown in FIGS. 2B and 2C, the LED bracket 6 on the front surface of the LED 61 is disposed below the case top 11 (decorative panel 11a), specifically, the case upper 11 (decorative panel 11a). Has a depth of H. The depth H is a depth at which the wall surface of the housing portion of the camera cover 21 and the LED bracket 6 does not come into contact with the tangent line L1 connecting the vertexes of the wall surface S1 on the camera portion side.

また、LEDブラケット６の収容部のうち、カメラ部側の壁面S1とLEDブラケット６との間で形成される角度が直角であって、他の壁面S2は鈍角で構成している。これにより、カメラカバー２１には、LED６１からの光が照射されにくく、玄関子機の前面にいる来訪者を確実に照射することができ、良好な映像を得ることが可能となる。 Further, in the housing portion of the LED bracket 6, the angle formed between the wall surface S1 on the camera unit side and the LED bracket 6 is a right angle, and the other wall surface S2 is an obtuse angle. Thereby, it is difficult for the light from the LED 61 to be irradiated on the camera cover 21, so that it is possible to reliably irradiate the visitors who are in front of the entrance unit, and it is possible to obtain a good image.

なお、カメラ部側の壁面S1は、直角に限られず、上述のようにカメラカバー２１とLEDブラケット６の収容部の壁面のうちカメラ部側の壁面S1の頂点を結ぶ接線L1に接触しない位置となる深さHを有していればよい（図３の要部断面図参照）。
また、他の壁面S2のうち、カメラ部側の壁面に対抗する位置にある壁面S2’は、LEDブラケット６との間で形成される角度が鈍角θで形成されている。そして、確実にLED６１が照射した光が反射し、反射光がカメラカバー２１に入射しないようにするため、カメラカバー２１とカメラ部側の壁面S1の頂点を結ぶ接線L1に対する垂線L2より大きい角度θ’（θ’＝θ−90°）としている。 The wall surface S1 on the camera unit side is not limited to a right angle, and as described above, the position does not contact the tangent line L1 connecting the apex of the wall surface S1 on the camera unit side among the wall surfaces of the camera cover 21 and the housing portion of the LED bracket 6. It is only necessary to have a depth H (refer to the cross-sectional view of the main part in FIG. 3).
Further, among the other wall surfaces S2, a wall surface S2 ′ located at a position facing the wall surface on the camera unit side is formed with an obtuse angle θ between the LED bracket 6 and the wall surface S2 ′. Then, in order to ensure that the light irradiated by the LED 61 is reflected and the reflected light does not enter the camera cover 21, an angle θ greater than the perpendicular L2 with respect to the tangent line L1 connecting the camera cover 21 and the apex of the wall surface S1 on the camera unit side. '(Θ' = θ-90 °).

このように構成されたインターホンの玄関子機１において、来訪者が居住者を呼び出すために呼出ボタン５を操作すると、呼出確認音が、スピーカ４から報音される。また、これと同時に、インターホンの居室親機（図示せず）から供給された電源によって、カメラ２が駆動すると共にLED６１が来訪者を照射する。 When the visitor operates the call button 5 in order to call a resident in the intercom entrance handset 1 configured as described above, a call confirmation sound is reported from the speaker 4. At the same time, the camera 2 is driven and the LED 61 irradiates the visitor by the power supplied from the interphone room master (not shown).

LED６１が照射した光はLEDブラケット６を介して来訪者を照射することになる。このとき直接光としてカメラカバー２１側方向への光は、深さHを有する壁面にて反射するため光がカメラカバー２１に映りこむことがない。 The light irradiated by the LED 61 irradiates the visitor through the LED bracket 6. At this time, the light directed toward the camera cover 21 as direct light is reflected by the wall surface having the depth H, so that the light is not reflected on the camera cover 21.

また、他の壁面S2(S2’)で反射した光は、壁面が鈍角である角度θをもつことにより、カメラカバー２１の頂点に影響することがなく来訪者を広範囲にわたって照射することができる。また、カメラ部側の壁面S1に対抗する位置にある壁面S2’は、特にカメラカバー２１とカメラ部側の壁面S1の頂点を結ぶ接線L1に対する垂線L2より大きい角度θ’（θ’＝θ−90°）としているため、反射光がカメラカバー２１に入射することがなく、良好な映像を得ることができる。 Further, the light reflected by the other wall surface S2 (S2 ') has an angle θ that is an obtuse wall surface, so that it is possible to irradiate visitors over a wide range without affecting the vertex of the camera cover 21. In addition, the wall surface S2 ′ located at the position facing the wall surface S1 on the camera unit side is an angle θ ′ (θ ′ = θ− 90 °), the reflected light does not enter the camera cover 21 and a good image can be obtained.

この映像を確認した居住者が、応答することで来訪者の映像を確認しながら通話を行うことができる。 A resident who has confirmed the video can make a call while checking the video of the visitor by responding.
