電子機器及び電子機器に装着可能なリング状部材Electronic device and ring-shaped member that can be attached to electronic device
　本発明は、機器本体に対してアダプターリング等のリング状部材を着脱可能に装着してなる電子機器、及び電子機器に装着可能なリング状部材に関するものである。 The present invention relates to an electronic device in which a ring-shaped member such as an adapter ring is detachably mounted on a device body, and a ring-shaped member that can be mounted on the electronic device.
　従来、光学フィルター等の補助光学部品をカメラ本体に装着するために、カメラ本体にアダプターリングを取り付け、該アダプターリングの内周面に形成された内ネジに対して補助光学部品をねじ込む構造が採用されている。 Conventionally, in order to mount auxiliary optical components such as optical filters on the camera body, an adapter ring is attached to the camera body, and the auxiliary optical components are screwed into the internal threads formed on the inner peripheral surface of the adapter ring. Has been.
　カメラ本体にアダプターリングを取り付けるための構造としては、一般に、バネによって一方向に付勢された可動式のフック片をアダプターリングに配備する一方、カメラ本体には前記フック片が係合すべきフック受け部を形成してなるフック機構が採用されている(特許文献１)。 As a structure for attaching the adapter ring to the camera body, generally, a movable hook piece biased in one direction by a spring is arranged on the adapter ring, while the hook piece to be engaged with the camera body is provided.

　しかしながら、カメラ本体にアダプターリングを取り付けるための着脱機構として上述のフック機構を採用した場合、フック片を可動構造とすると共に、該フック片を一方向に付勢するバネを配備する必要があり、これによって構造が複雑となる問題があった。 However, when the above-described hook mechanism is used as an attachment / detachment mechanism for attaching the adapter ring to the camera body, the hook piece needs to be a movable structure and a spring that urges the hook piece in one direction must be provided. This has a problem that the structure becomes complicated.
　そこで本発明の目的は、機器本体に対してリング状部材を着脱可能に装着してなる電子機器において、着脱機構の簡易化を図ることである。 Therefore, an object of the present invention is to simplify the attachment / detachment mechanism in an electronic device in which a ring-shaped member is detachably attached to the device main body.
　本発明に係る電子機器においては、機器本体に対してリング状部材が着脱可能に装着されており、リング状部材には、その周方向にずれた位置に、複数の係合片が突設される一方、機器本体には、前記係合片がそれぞれ係合すべき複数の係合受け部が形成されており、リング状部材を一方向に挟圧してリング状部材を弾性変形させる操作と、リング状部材に対する挟圧を解除してリング状部材を弾性復帰させる操作によって、前記係合片を係合受け部に対して係脱させることが可能である。 In the electronic apparatus according to the present invention, a ring-shaped member is detachably attached to the apparatus main body, and a plurality of engagement pieces project from the ring-shaped member at positions shifted in the circumferential direction. On the other hand, the device main body is formed with a plurality of engagement receiving portions to be engaged with the engagement pieces, respectively, and the ring-shaped member is clamped in one direction to elastically deform the ring-shaped member; The engagement piece can be engaged with and disengaged from the engagement receiving portion by releasing the clamping pressure on the ring-shaped member and elastically returning the ring-shaped member.
　上記電子機器において、機器本体に対してリング状部材を取り付けるときは、リング状部材を一方向に挟圧し、リング状部材を弾性変形によって湾曲させる。これによって、リング状部材の複数の係合片がリング状部材の内側若しくは外側に向かって弾性変位することになる。この状態で、リング状部材を機器本体に装着し、リング状部材の挟圧を解除する。
　この結果、リング状部材が弾性復帰し、これに伴って、リング状部材の複数の係合片が機器本体の複数の係合受け部にそれぞれ係合し、これによってリング状部材が機器本体に係止されることになる。 In the electronic device, when the ring-shaped member is attached to the device main body, the ring-shaped member is pressed in one direction, and the ring-shaped member is bent by elastic deformation. As a result, the plurality of engagement pieces of the ring-shaped member are elastically displaced toward the inside or the outside of the ring-shaped member. In this state, the ring-shaped member is attached to the apparatus main body, and the clamping pressure of the ring-shaped member is released.
As a result, the ring-shaped member is elastically restored, and accordingly, the plurality of engagement pieces of the ring-shaped member are respectively engaged with the plurality of engagement receiving portions of the device main body, whereby the ring-shaped member is attached to the device main body. Will be locked.
　機器本体からリング状部材を取り外すときは、リング状部材を一方向に挟圧し、リング状部材を弾性変形させる。これによって、リング状部材の複数の係合片が弾性変位することになる。これに伴って、リング状部材の複数の係合片が機器本体の複数の係合受け部からそれぞれ離脱する。
　この状態で、リング状部材を機器本体から取り外し、リング状部材の挟圧を解除する。これによって、リング状部材が弾性復帰する。 When removing the ring-shaped member from the device main body, the ring-shaped member is pressed in one direction to elastically deform the ring-shaped member. As a result, the plurality of engagement pieces of the ring-shaped member are elastically displaced. Accordingly, the plurality of engagement pieces of the ring-shaped member are detached from the plurality of engagement receiving portions of the device main body, respectively.
In this state, the ring-shaped member is removed from the device main body, and the pinching pressure of the ring-shaped member is released. As a result, the ring-shaped member is elastically restored.
　具体的態様において、前記リング状部材は円筒体を呈し、その内周面に内ネジが形成されている。
　該具体的態様によれば、機器本体にリング状部材を装着した状態で、該リング状部材の内ネジに、各種若しくは特定の部品、部材、器具等をねじ込むことが出来る。 In a specific aspect, the ring-shaped member has a cylindrical body, and an inner screw is formed on an inner peripheral surface thereof.
According to the specific aspect, various or specific parts, members, instruments, and the like can be screwed into the inner screw of the ring-shaped member in a state where the ring-shaped member is mounted on the apparatus main body.
　又、具体的態様において、前記複数の係合片は、前記リング状部材の筒軸を中心として１８０度の角度差を有する２つの位置に突設されている。
　この場合、前記２つの位置とは９０度ずれた２つの位置にて、リング状部材を挟圧して、リング状部材を楕円状に湾曲させる。 Further, in a specific aspect, the plurality of engaging pieces are protruded at two positions having an angular difference of 180 degrees around the cylindrical axis of the ring-shaped member.
In this case, the ring-shaped member is clamped at two positions shifted by 90 degrees from the two positions, and the ring-shaped member is bent into an elliptical shape.
　他の具体的態様において、前記リング状部材には、前記２つの位置とは９０度ずれた２つの位置に、リング状部材のその位置での断面積を縮小する切り欠きがそれぞれ形成されている。
　これによって、リング状部材の弾性変形が容易なものとなる。 In another specific aspect, the ring-shaped member is formed with notches that reduce the cross-sectional area at the position of the ring-shaped member at two positions shifted by 90 degrees from the two positions. .
Thereby, the elastic deformation of the ring-shaped member is facilitated.
　更に具体的な態様において、前記係合片は、先端が前記リング状部材の内側へ向けてＬ字状に屈曲するフック片によって形成される一方、前記係合受け部は、リング状部材が装着されるべきリング状部分の内側へ向けて凹むフック受け凹部によって形成されている。
　この場合、リング状部材を着脱する際には、各フック片をフック受け凹部から脱出させる方向に、リング状部材を湾曲させる。 In a more specific aspect, the engagement piece is formed by a hook piece whose tip is bent in an L shape toward the inside of the ring-shaped member, while the engagement receiving portion is attached to the ring-shaped member. It is formed by a hook receiving recess that is recessed toward the inside of the ring-shaped portion to be formed.
In this case, when attaching and detaching the ring-shaped member, the ring-shaped member is bent in a direction in which each hook piece is escaped from the hook receiving recess.
　又、本発明に係るリング状部材は、電子機器に装着することが可能なリング状部材であって、リング状本体と、リング状本体の周方向にずれた位置に突設された複数の係合片とを具え、リング状本体を一方向に挟圧してリング状本体を弾性変形させる操作と、リング状本体に対する挟圧を解除してリング状本体を弾性復帰させる操作によって、装着相手となる電子部品に形成された係合受け部に対して前記係合片を係脱させることが可能である。 The ring-shaped member according to the present invention is a ring-shaped member that can be attached to an electronic device, and includes a ring-shaped main body and a plurality of engagement members protruding at positions shifted in the circumferential direction of the ring-shaped main body. It becomes an attachment partner by an operation of holding the ring-shaped main body in one direction and elastically deforming the ring-shaped main body and an operation of releasing the pressure on the ring-shaped main body and elastically returning the ring-shaped main body. The engagement piece can be engaged with and disengaged from an engagement receiving portion formed on the electronic component.
　本発明に係る電子機器及び電子機器に装着可能なリング状部材によれば、機器本体に対してリング状部材を着脱可能に装着するための機構として、リング状部材全体の弾性変形を利用した着脱機構が採用されているので、従来の着脱機構におけるフック片の可動構造やフック片を付勢するバネは不要となり、これによって着脱機構の簡易化が実現される。 According to the electronic device and the ring-shaped member that can be attached to the electronic device according to the present invention, as a mechanism for detachably attaching the ring-shaped member to the device main body, the attachment / detachment using elastic deformation of the entire ring-shaped member. Since the mechanism is employed, the movable structure of the hook piece and the spring for urging the hook piece in the conventional attaching / detaching mechanism are not necessary, thereby simplifying the attaching / detaching mechanism.
