Description

本発明は、例えば、携帯電話機やパソコン等に付設されるカメラ等に露出制御用として設けられるシャッター羽根に関する。   The present invention relates to a shutter blade provided for exposure control in, for example, a camera attached to a mobile phone, a personal computer, or the like.

露出時間を制御するためのシャッター羽根には高速で正確な動作が要求されるため、その羽根を駆動させる駆動部分が羽根本体と確実に固定されている必要がある。例えば、一体成型により、羽根母材を駆動部分となる鋲部及び鋲突出部に固定するようにした露出制御用羽根（絞り羽根）とその製造方法が提案されている（例えば、特許文献１参照）。   Since the shutter blade for controlling the exposure time is required to operate at high speed and accurately, the driving portion for driving the blade needs to be securely fixed to the blade body. For example, an exposure control blade (aperture blade) in which a blade base material is fixed to a collar portion and a collar protrusion as a driving portion by integral molding and a manufacturing method thereof have been proposed (for example, see Patent Document 1). ).

この例では、図３に示すように、羽根母材１に鋲部２１、鋲突出部２２の径よりも小径な孔部１１，１２を形成し、かつ、それぞれ鋲部２１及び鋲突出部２２の上半分と下半分に相当するキャビティを有する上金型と下金型の間に羽根母材１を配置して、キャビティに溶融樹脂を射出して、羽根母材１の表裏両面に突出する鋲部２１と鋲突出部２２を一体的に形成するようにしている。なお、鋲部３１、鋲突出部３２も同様に形成される。
特許第２７０７６２２号公報 In this example, as shown in FIG. 3, holes 11 and 12 having a diameter smaller than the diameter of the flange 21 and the flange protrusion 22 are formed in the blade base material 1, and the flange 21 and the flange protrusion 22 are respectively formed. The blade base material 1 is disposed between the upper mold and the lower mold having cavities corresponding to the upper half and the lower half of the mold, and the molten resin is injected into the cavity so as to protrude on both the front and back surfaces of the blade base material 1. The flange portion 21 and the flange protrusion portion 22 are integrally formed. In addition, the collar part 31 and the collar protrusion part 32 are formed similarly.
Japanese Patent No. 2707622

しかし、例えば、図４に示すシャッター羽根のように、羽根本体１の基部１ａに形成した軸孔にカラン２を嵌め込むと共にカラン２の軸部に磁石３を嵌め込んで基部１ａとカラン２及び磁石３を一体化し、磁石３に磁力を作用させることによって羽根本体１をカラン２に挿通させた支軸（図示省略）のまわりに回動動作させるように構成する場合、羽根本体１の回動動作時には基部１ａに大きなモーメントが作用する。   However, for example, like the shutter blade shown in FIG. 4, the currant 2 is fitted into the shaft hole formed in the base portion 1 a of the blade body 1, and the magnet 3 is fitted into the shaft portion of the currant 2, and the base portion 1 a and the currant 2 and When the magnet 3 is integrated and a magnetic force is applied to the magnet 3 to rotate the blade body 1 around a support shaft (not shown) inserted through the currant 2, the blade body 1 rotates. During operation, a large moment acts on the base 1a.

従って、特に、羽根本体１の基部１ａと磁石３は滑りが生じないように強固に一体化されていなければならない。この点に関し、基部１ａとカラン２及び磁石３を接着剤で一体化する場合、対応する平面間に接着剤層を介在させただけでは、モーメントの作用方向に沿う方向に接着面が形成されるため充分な滑り止め効果が得られないことが懸念される。また、カラン２を樹脂材の一体成型によって形成することで羽根本体１の基部１ａと磁石３を一体化する場合においても同様である。   Therefore, in particular, the base 1a of the blade body 1 and the magnet 3 must be firmly integrated so as not to slip. In this regard, when the base 1a, the currant 2 and the magnet 3 are integrated with an adhesive, an adhesive surface is formed in a direction along the direction of the moment only by interposing the adhesive layer between the corresponding planes. Therefore, there is a concern that a sufficient anti-slip effect cannot be obtained. The same applies to the case where the base 1a of the blade body 1 and the magnet 3 are integrated by forming the currant 2 by integral molding of a resin material.

本発明は、このような実情に鑑みてなされ、羽根基部と磁石の間に滑りが生じないようにこれらを強固に一体化できるようにしたシャッター羽根を提供することを目的とする。   The present invention has been made in view of such circumstances, and an object of the present invention is to provide a shutter blade that can be firmly integrated so that no slip occurs between the blade base and the magnet.

（１）本発明のシャッター羽根は、支軸に回動自在に被嵌されるカランと羽根基部と磁石とが一体化され、前記磁石に作用する磁力によって前記支軸のまわりに回動動作するシャッター羽根であって、
前記羽根基部には、前記カランを挿通させるための軸孔が形成され、かつ、該軸孔の近傍位置に、前記羽根基部と磁石を一体化するための素材を充填させる切り抜き部が形成されることを特徴とする。 (1) In the shutter blade of the present invention, the curan that is rotatably fitted to the support shaft, the blade base, and the magnet are integrated, and the shutter blade is rotated around the support shaft by the magnetic force acting on the magnet. Shutter blades,
A shaft hole for inserting the currant is formed in the blade base portion, and a cutout portion for filling a material for integrating the blade base portion and the magnet is formed at a position near the shaft hole. It is characterized by that.

このような構成によれば、切り抜き部に充填された一体化のための素材が、シャッター羽根の回動動作時に羽根基部に作用するモーメントの作用方向に直交する方向に立ち上がる形となるため、羽根基部と磁石との間の滑りを阻止するための効果的な抵抗要素となり、強固な一体化が可能となる。
（２）前記羽根基部と磁石を一体化するための素材が樹脂材であり、該樹脂材の一体成型によって前記カランが形成され、前記カランは、前記羽根基部の軸孔に挿通される軸部と、該軸部の一端に形成されるフランジ部を有し、前記磁石には、前記カランの軸部に挿通される貫通孔が形成され、前記カランの軸部が前記羽根基部の軸孔に挿通され、かつ、前記磁石の貫通孔に前記カランの軸部が挿通され、前記フランジ部と磁石の間に前記羽根基部が挟持された状態にて、前記切り抜き部に充填された前記樹脂材を介して前記羽根基部と磁石が一体化されるようにしてもよい。 According to such a configuration, since the material for integration filled in the cutout portion rises in a direction perpendicular to the direction of the moment acting on the blade base when the shutter blade rotates, the blade It becomes an effective resistance element for preventing the slip between the base and the magnet, and strong integration becomes possible.
(2) The material for integrating the blade base and the magnet is a resin material, the curan is formed by integral molding of the resin material, and the curan is inserted into the shaft hole of the blade base. A flange portion formed at one end of the shaft portion, and the magnet has a through-hole inserted into the shaft portion of the currant, and the shaft portion of the currant is formed in the shaft hole of the blade base portion. The resin material filled in the cutout portion is inserted in a state where the shaft portion of the currant is inserted through the through hole of the magnet and the blade base portion is sandwiched between the flange portion and the magnet. The blade base and the magnet may be integrated with each other.

このようにすれば、切り抜き部に充填された樹脂材が、シャッター羽根の回動動作時に羽根基部に作用するモーメントの作用方向に直交する方向に立ち上がる形となるため、羽根基部と磁石との間の滑りを阻止するための効果的な抵抗要素となり、強固な一体化が可能となる。また、樹脂材の一体成型により製作容易であるため、安価に提供することができる。
（３）前記羽根基部と磁石を一体化するための素材が接着剤であり、前記カランは、前記羽根基部の軸孔に挿通される軸部と、該軸部の一端に形成されるフランジ部とを有し、前記磁石には、前記カランの軸部に挿通される貫通孔が形成され、前記カランの軸部が前記羽根基部の軸孔に挿通され、かつ、前記磁石の貫通孔に前記カランの軸部が挿通され、前記フランジ部と磁石の間に前記羽根基部が挟持された状態にて、前記切り抜き部に充填された前記接着剤を介して前記フランジ部と羽根基部と磁石が一体化されるようにしてもよい。 In this way, the resin material filled in the cut-out portion rises in a direction perpendicular to the direction of the moment acting on the blade base during the rotation of the shutter blade, so that there is a gap between the blade base and the magnet. It becomes an effective resistance element for preventing the slippage of the material, and can be firmly integrated. Moreover, since it is easy to manufacture by integral molding of the resin material, it can be provided at low cost.
(3) The material for integrating the blade base and the magnet is an adhesive, and the curan includes a shaft portion inserted into the shaft hole of the blade base, and a flange portion formed at one end of the shaft portion. The magnet has a through hole inserted through the shaft portion of the curan, the shaft portion of the curan is inserted through the shaft hole of the blade base, and the through hole of the magnet The flange portion, the blade base portion and the magnet are integrated with each other through the adhesive filled in the cutout portion in a state where the shaft portion of the currant is inserted and the blade base portion is sandwiched between the flange portion and the magnet. It may be made to be.

このようにすれば、切り抜き部に充填された接着剤が、シャッター羽根の回動動作時に羽根基部に作用するモーメントの作用方向に直交する方向に立ち上がる形となるため、羽根基部と磁石との間の滑りを阻止するための効果的な抵抗要素となり、強固な一体化が可能となる。また、接着剤により３つの部材（カランと羽根基部と磁石）を一度に一体化できるため製作容易であり、安価に提供することができる。   In this way, the adhesive filled in the cut-out portion rises in a direction perpendicular to the direction of the moment acting on the blade base during the rotation of the shutter blade, so that the gap between the blade base and the magnet is increased. It becomes an effective resistance element for preventing the slippage of the material, and can be firmly integrated. In addition, since the three members (curran, blade base and magnet) can be integrated at once by an adhesive, it is easy to manufacture and can be provided at low cost.

本発明のシャッター羽根は、羽根基部の軸孔の近傍位置に形成した切り抜き部に充填された一体化のための素材が、シャッター羽根の回動動作時に羽根基部に作用するモーメントの作用方向に直交する方向に立ち上がる形となるため、羽根基部と磁石の間の滑りを阻止するための効果的な抵抗要素となり、強固な一体化が可能となる。   In the shutter blade according to the present invention, the material for integration filled in the cutout portion formed in the vicinity of the shaft hole of the blade base is orthogonal to the direction of the moment acting on the blade base when the shutter blade rotates. Therefore, it becomes an effective resistance element for preventing slippage between the blade base and the magnet, and can be firmly integrated.

[Embodiment 1]
In the present embodiment, the shutter blade is configured such that the blade body and the magnet are integrated via a currant formed by integral molding of a resin material, and FIG. 1A is a plan view of the blade body. (b) is a cross-sectional view of the shutter blade 1A, and (c) is a plan view of the shutter blade 1A. In these drawings, reference numeral 1 denotes a blade body, a shaft hole 1b is formed in the base portion (blade base portion of the present invention) 1a, and cutout portions 1c and 1d are formed in the vicinity of the shaft hole 1b. Has been. Reference numeral 2 denotes a currant, which has a shaft portion 2a inserted through a shaft hole 1b formed in the base portion 1a of the blade body 1 and flange portions 2b and 2c formed at both ends of the shaft portion 2a. Reference numeral 3 denotes a magnet, which has a through hole 3a inserted into the shaft portion 2a of the currant 2 and is formed in an annular shape.

図１（ｂ）（ｃ）は、羽根本体１とカラン２と磁石３が、カラン２を形成する樹脂材の一体成型によって一体化されたシャッター羽根１Ａを示す。この状態では、カラン２の軸部２ａが、羽根本体１の基部１ａの軸孔１ｂに挿通され、かつ、磁石３の貫通孔３ａにカラン２の軸部２ａが挿通され、一方のフランジ部２ｂと磁石３の一面との間に基部１ａが挟持され、切り抜き部１ｃ，１ｄに充填された樹脂材ｒを介してカラン２と羽根本体１の基部１ａと磁石３が一体化され、他方のフランジ部２ｃは磁石３の他面に密着して、磁石３の両面がカラン２の両フランジ部２ｂ，２ｃに挟持されている。   FIGS. 1B and 1C show a shutter blade 1 </ b> A in which a blade body 1, a currant 2, and a magnet 3 are integrated by integral molding of a resin material forming the currant 2. In this state, the shaft portion 2a of the currant 2 is inserted through the shaft hole 1b of the base portion 1a of the blade body 1, and the shaft portion 2a of the currant 2 is inserted through the through-hole 3a of the magnet 3, and one flange portion 2b. 1a and the magnet 3 is sandwiched between the base 1a, the currant 2, the base 1a of the blade body 1 and the magnet 3 are integrated through the resin material r filled in the cutouts 1c and 1d, and the other flange. The portion 2 c is in close contact with the other surface of the magnet 3, and both surfaces of the magnet 3 are sandwiched between both flange portions 2 b and 2 c of the currant 2.

このようなシャッター羽根１Ａは、図示は省略するが、例えば、羽根本体１の基部１ａと磁石３を配置したキャビティに樹脂材を充填することによって、羽根本体１と磁石３をカラン２と共に一体成型することによって容易に得ることができ、安価に提供することができる。その樹脂材には、例えば、潤滑性の良好なポリアセタール（ＰＯＭ）を用いたジュラコン（商品名）等を用いることができる。なお、磁石３は一体成型後に着磁させれば、成型時の熱による磁力への影響を回避することができる。   The shutter blade 1A is not shown in the figure, but, for example, the blade body 1 and the magnet 3 are integrally molded together with the currant 2 by filling a resin material in a cavity in which the base 1a of the blade body 1 and the magnet 3 are arranged. This can be easily obtained and can be provided at a low cost. As the resin material, for example, Duracon (trade name) using polyacetal (POM) with good lubricity can be used. In addition, if the magnet 3 is magnetized after integral molding, the influence on the magnetic force by the heat | fever at the time of shaping | molding can be avoided.

このシャッター羽根１Ａは、カラン２の軸部２ａを支軸（図示省略）に回動自在に挿通させ、磁石３に磁力を作用させることによって支軸のまわりに回動動作する。その際に、切り抜き部１ｃ，１ｄに充填された樹脂材（カラン２の一部）ｒが、羽根本体１の基部１ａと磁石３の間の滑りの発生を阻止するための効果的な抵抗要素として機能する。即ち、その樹脂材ｒが、切り抜き部１ｃ，１ｄの内壁面及び磁石３と一体化されて、シャッター羽根１Ａの回動動作時に基部１ａに作用するモーメントの作用方向（図１（ｂ）の状態では紙面に直交する方向）に対して直交する方向に立ち上がる形となるため、その樹脂材ｒによって、羽根本体１の基部１ａと磁石３の間の滑りの発生が効果的に阻止されることとなり、基部１ａと磁石３が強固な一体化状態に保持され、シャッター羽根１の回動動作が高精度に維持される。
〔実施の形態２〕
本実施の形態では、接着剤により、カランと羽根本体と磁石が一体化されるように構成され、図２（ａ）は羽根本体の平面図、（ｂ）はシャッター羽根の組み付け対応図、（ｃ）はシャッター羽根１Ｂの断面図である。これらの図にて、前実施の形態と同等又は同一部材については同一符号を付し、その説明を省略する。この例では、カラン２は、軸部２ａの一端側にのみフランジ部２ｂが形成されており、ポリカーボネート等の接着性の良好な樹脂材からなる成型品が好ましい。 The shutter blade 1A rotates around the support shaft by inserting the shaft portion 2a of the currant 2 into a support shaft (not shown) so as to freely rotate and applying a magnetic force to the magnet 3. At that time, an effective resistance element for preventing the occurrence of slipping between the base portion 1a of the blade body 1 and the magnet 3 by the resin material (part of the currant 2) r filled in the cutout portions 1c and 1d. Function as. That is, the resin material r is integrated with the inner wall surfaces of the cut-out portions 1c and 1d and the magnet 3, and the acting direction of the moment acting on the base portion 1a when the shutter blade 1A is rotated (state of FIG. 1B) In this case, the resin material r effectively prevents the occurrence of slipping between the base portion 1a of the blade body 1 and the magnet 3. The base 1a and the magnet 3 are held in a strong integrated state, and the rotation operation of the shutter blade 1 is maintained with high accuracy.
[Embodiment 2]
In the present embodiment, the currant, the blade main body, and the magnet are configured to be integrated by an adhesive, FIG. 2 (a) is a plan view of the blade main body, (b) is an assembly correspondence diagram of the shutter blade, c) is a sectional view of the shutter blade 1B. In these drawings, the same reference numerals are given to the same or the same members as those of the previous embodiment, and the description thereof is omitted. In this example, the currant 2 is formed with a flange portion 2b only on one end side of the shaft portion 2a, and is preferably a molded product made of a resin material having good adhesion such as polycarbonate.

この場合、図２（ｂ）に示すように、カラン２の軸部２ａを羽根本体１の軸孔１ｂに挿入して、その軸孔１ｂと軸部２ａの境目及び切り抜き部１ｃ，１ｄに接着剤ｂを付着させた後、カラン２の軸部２ａに磁石３を被嵌させ、磁石３を羽根本体１の基部１ａに押し付けて羽根本体１の基部１ａを磁石３とフランジ部２ｂの間に挟み付けて接着剤ｂを展延させ、この状態で接着剤ｂを硬化させると、羽根本体１とカラン２と磁石３を一体化することができる。この例では、切り抜き部１ｃを円弧状の長孔に形成しているため、接着面積をより広くとれることから、より強固な接着力が得られる。なお、接着剤ｂにはエポキシ系等の接着剤を用いることができる。   In this case, as shown in FIG. 2 (b), the shaft portion 2a of the currant 2 is inserted into the shaft hole 1b of the blade body 1, and bonded to the boundary between the shaft hole 1b and the shaft portion 2a and the cutout portions 1c and 1d.

By sandwiching and spreading the adhesive b, and curing the adhesive b in this state, the blade body 1, the currant 2 and the magnet 3 can be integrated. In this example, since the cut-out portion 1c is formed in an arc-shaped long hole, the adhesion area can be increased, and thus a stronger adhesion force can be obtained. Note that an epoxy-based adhesive or the like can be used for the adhesive b.

本実施の形態においても、切り抜き部１ｃ，１ｄに充填された接着剤ｂが、カラン２のフランジ部２ｂ、切り抜き部１ｃ，１ｄの内壁面及び磁石３に接着して、シャッター羽根１Ａの回動動作時に基部１ａに作用するモーメントの作用方向（図１（ｂ）の状態では紙面に直交する方向）に対して直交する方向に立ち上がる形となるように硬化しているため、その接着剤ｂが、羽根本体１の基部１ａと磁石３の間の滑りの発生を阻止するための効果的な抵抗要素として機能し、基部１ａと磁石３が強固な一体化状態で安定に保持されることとなり、シャッター羽根１Ｂの回動動作が高精度に維持される。   Also in the present embodiment, the adhesive b filled in the cutout portions 1c and 1d adheres to the flange portion 2b of the currant 2, the inner wall surface of the cutout portions 1c and 1d, and the magnet 3 to rotate the shutter blade 1A. Since the adhesive b is cured so as to rise in a direction perpendicular to the direction of action of the moment acting on the base 1a during operation (the direction perpendicular to the paper surface in the state of FIG. 1B), the adhesive b , Functioning as an effective resistance element for preventing the occurrence of slippage between the base 1a of the blade body 1 and the magnet 3, and the base 1a and the magnet 3 are stably held in a strong integrated state.
