【産業上の利用分野】[Industrial applications]

本考案は、カメラのシャッタ開閉機構に関する。 The present invention relates to a shutter opening / closing mechanism of a camera.

【0002】[0002]

【従来の技術】[Prior Art]

従来、カメラのシャッタ開閉機構には、駆動源とシャッタとの間の連結機構等 に生じるガタによるシャッタ開閉作動のばらつきを補正するために、シャッタに バネを係止させてその弾性力によってシャッタを開放方向又は閉鎖方向に付勢し ておく構造を有するものが多い。 このようなシャッタ開閉機構の一例を図3により説明する。 図3はシャッタ開閉機構の要部平面図であり、開口部1が形成されたシャッタ 地板2の表面(紙面表側)には、夫々支軸3,4を中心に回動可能に支持された 一対のシャッタ羽根5,6が設けられている。シャッタ地板2の裏面(紙面裏側 )には駆動源である駆動モータ7が取付られており、その駆動軸に一端が連結さ れた開閉レバー8の他端には駆動ピン8aが設けられていて、駆動ピン8aは駆 動モータ7の回動範囲で所定角度だけ往復動し得るようになっている。 この駆 動ピン8aは、その回動範囲に沿ってシャッタ地板2に穿設された略小判型孔2 aを貫通して地板2の表側に突出しており、一対のシャッタ羽根5,6の各スロ ット5a,6aとピン−スロット連結されている。これにより、駆動ピン8aの 往復動によってシャッタ羽根5,6を開閉作動できるようになっている。 Conventionally, in a shutter opening / closing mechanism of a camera, in order to correct variation in shutter opening / closing operation due to play in a connecting mechanism between a drive source and the shutter, a spring is locked to the shutter and the shutter is elastically actuated. Many of them have a structure that biases them in the opening direction or the closing direction. An example of such a shutter opening / closing mechanism will be described with reference to FIG. FIG. 3 is a plan view of a main part of the shutter opening / closing mechanism. A pair of shutter base plates 2 having openings 1 formed therein are rotatably supported about support shafts 3 and 4, respectively. Shutter blades 5 and 6 are provided. A drive motor 7 as a drive source is attached to the back surface (back side of the paper) of the shutter base plate 2, and a drive pin 8a is provided at the other end of an opening / closing lever 8 whose one end is connected to its drive shaft. The drive pin 8a can reciprocate by a predetermined angle within the rotation range of the drive motor 7. The drive pin 8a penetrates a substantially oval-shaped hole 2a formed in the shutter base plate 2 along its rotation range and projects to the front side of the base plate 2, and each of the pair of shutter blades 5 and 6. It is connected to the slots 5a and 6a by a pin-slot. As a result, the shutter blades 5 and 6 can be opened and closed by the reciprocating movement of the drive pin 8a.

【0003】 又、一方のシャッタ羽根5の支軸3には、ガタ取り用のコイルバネ10のコイ ル部がゆるく巻回されており、その一端は一方のシャッタ羽根5の係止用小穴5 bに掛け止めされ、他端は他方のシャッタ羽根6の係止用長孔6bに掛け止めさ れている。そして、このコイルバネ10はシャッタ羽根5,6を閉鎖させる方向 に付勢されている。A coil portion of a coil spring 10 for loosening is loosely wound around the support shaft 3 of one shutter blade 5, one end of which has a small hole 5 b for locking one shutter blade 5. The other end of the shutter blade 6 is hooked on the locking long hole 6b. The coil spring 10 is biased in a direction to close the shutter blades 5 and 6.

【0004】 このような構成のもとで、図3ではシャッタ羽根5,6はコイルバネ10の付 勢力で、実線で示すように開口部1を覆った閉鎖状態に保持されている。 シャッタを開放作動させる場合には、駆動モータ7を図上で左旋(反時計方向 の回動)させると、駆動ピン8aの回動によりピン−スロット連結を介してシャ ッタ羽根5,6が連動し、コイルバネ10の付勢力に抗して開放作動させられる 。そして、開放状態では、図3で一点鎖線で示すようにシャッタ羽根5,6は開 口部1から外れ、コイルバネ10も大きく開かれた状態に保持される。 開放状態から閉鎖作動させる場合には、駆動モータ7を逆方向に回転させるこ とにより、コイルバネ10の付勢力が加わって高速でシャッタ羽根5,6が閉鎖 作動させられる。With such a configuration, in FIG. 3, the shutter blades 5 and 6 are held in a closed state of covering the opening 1 by the biasing force of the coil spring 10 as shown by the solid line. When the drive motor 7 is rotated counterclockwise (counterclockwise) in the case of opening the shutter, the drive pins 8a rotate to cause the shutter blades 5 and 6 to move through the pin-slot connection. In conjunction with this, the opening operation is performed against the biasing force of the coil spring 10. In the open state, the shutter blades 5 and 6 are separated from the opening 1 as shown by the chain line in FIG. 3, and the coil spring 10 is also held in a wide open state. When the closing operation is performed from the open state, by rotating the drive motor 7 in the opposite direction, the biasing force of the coil spring 10 is applied to close the shutter blades 5 and 6 at high speed.

【考案が解決しようとする課題】[Problems to be solved by the device]

ところで、このような構造のシャッタ開閉機構では、シャッタの開口位置に応 じてコイルバネ10の巻き込み角度即ち両端部間の角度が変化するため、バネ1 0自体の力量がこの角度に応じて変化するものであった。そのため、シャッタ羽 根の閉じ位置付近のバネ力量と全開付近のバネ力量とでは大きな差があった。 従って、特にシャッタが絞り兼用である場合、開口径の大きさ即ち絞り径の大 きさによって開閉作動時のメカ遅れにバラツキがあり、露光量が不正確且つ不安 定になる欠点がある。又、羽根全開時に完全に開くような力量のコイルバネを用 いると、小絞り時にはバネの力量が弱いために閉鎖作動速度が小さくなり、小絞 り時のシャッタ速度を速くすることが困難であった。 By the way, in the shutter opening / closing mechanism having such a structure, since the winding angle of the coil spring 10, that is, the angle between both ends, changes according to the opening position of the shutter, the force of the spring 10 itself changes according to this angle. It was a thing. Therefore, there was a large difference between the amount of spring force near the closed position of the shutter blade and the amount of spring force near full opening. Therefore, especially when the shutter also serves as an aperture, there is a disadvantage that the mechanical delay at the time of opening / closing operation varies due to the size of the aperture diameter, that is, the aperture diameter, and the exposure amount becomes inaccurate and unstable. Also, if a coil spring is used that has the force to open completely when the blade is fully opened, the closing operation speed will be low due to the weak force of the spring when the aperture is small, making it difficult to increase the shutter speed when the aperture is small. It was

【0006】 更に、開閉作動時に、コイルバネ10の巻き込み部における巻き込み量の変化 によってバネ10が地板2から立ってしまい、バネが掛け止め用の穴からはずれ てしまうこともある。これを防止しようとすれば、バネ10の巻き込み部を大径 化するかコイルの巻き数を増やす等してバネ10を大型にする必要があり、大き なスペースが必要であった。 又、全開状態では、コイルバネ10の力量が最大になるため、バネの設定力量 によってはシャッタ羽根に与える力が増大して羽根が変形することがあり、シャ ッタ開閉機構の耐久性に問題があった。又、開放作動時にコイルバネ10の付勢 力に抗してシャッタ速度を上げるには、大きな電力が必要である。 このように従来のシャッタ開閉機構のガタ防止用コイルバネ10には、多くの 問題があった。Further, during the opening / closing operation, the spring 10 may stand up from the base plate 2 due to a change in the amount of winding at the winding portion of the coil spring 10, and the spring may come off from the locking hole. In order to prevent this, it is necessary to enlarge the spring 10 by enlarging the winding portion of the spring 10 or increasing the number of windings of the coil, which requires a large space. Further, in the fully opened state, the force of the coil spring 10 is maximized, and therefore the force applied to the shutter blades may be increased and the blades may be deformed depending on the set force of the spring, which causes a problem in durability of the shutter opening / closing mechanism. there were. Further, in order to increase the shutter speed against the biasing force of the coil spring 10 during the opening operation, a large amount of electric power is required. As described above, the conventional coil spring 10 for preventing backlash of the shutter opening / closing mechanism has many problems.

【0007】 本考案は、このような課題に鑑みて、シャッタ羽根の開度に関わらずほぼ一定 の力量が掛かるようにして、作動時のガタを取り除くようにした付勢部材を有す るカメラのシャッタ開閉機構を提供することを目的とする。In view of the above problems, the present invention provides a camera having an urging member that removes play during operation by applying a substantially constant amount of force regardless of the opening of the shutter blade. It is an object of the present invention to provide a shutter opening / closing mechanism.

【課題を解決するための手段】[Means for Solving the Problems]

本考案によるカメラのシャッタ開閉機構は、開口部を開閉制御する複数のシャ ッタと、これらシャッタに連結されていて駆動源に連動してシャッタを開閉作動 させる開閉部材と、シャッタを開方向又は閉方向に付勢する付勢部材とを備えた カメラのシャッタ開閉機構において、付勢部材は回転可能であると共に、その一 端が一のシャッタに係止され、他端がこのシャッタとの連結部付近で開閉部材に 係止され、回転中心部がこのシャッタの回転中心軸付近に保持されていることを 特徴とするものである。 A shutter opening / closing mechanism of a camera according to the present invention includes a plurality of shutters for controlling opening / closing of an opening, an opening / closing member connected to the shutters for opening / closing the shutter in association with a driving source, and a shutter opening / closing direction. In a shutter opening / closing mechanism of a camera including a biasing member that biases in a closing direction, the biasing member is rotatable, one end of which is locked by one shutter, and the other end is connected to this shutter. It is characterized in that it is locked to the opening / closing member in the vicinity of the portion and the center of rotation is held near the center axis of rotation of this shutter.

【0009】[0009]

【作用】[Action]

シャッタ羽根の開放作動時に開閉部材が作動すると、シャッタ羽根が開き方向 に作動すると共に、付勢部材の他端も開閉部材と一体に回動させられるために付 勢部材は一方のシャッタの回転中心軸付近を中心に回動することになり、この付 勢部材の両端部間の角度はほぼ変化しないから、シャッタ羽根の開口径にかかわ らずこの付勢部材に働く付勢力はほぼ一定に保持され、又閉鎖作動時にも開閉部 材と一方のシャッタ羽根に連動して付勢部材も回動するために、付勢部材の付勢 力も開放作動時と同様にほぼ一定に保持される。 When the opening / closing member operates when the shutter blade opens, the shutter blade operates in the opening direction, and the other end of the biasing member is also rotated integrally with the opening / closing member, so that the biasing member is the center of rotation of one shutter. The urging force acts on this urging member, regardless of the opening diameter of the shutter blades, because the angle between both ends of this urging member does not change substantially because it rotates around the axis. In addition, since the biasing member also rotates in conjunction with the opening / closing member and the one shutter blade during the closing operation, the biasing force of the biasing member is maintained substantially constant as in the opening operation.

【実施例】【Example】

以下、本考案の好適な一実施例を図1及び図2に基づいて説明するが、上述の 従来技術と同様な部分又は部材には同一の符号を用いてその説明を省略する。 図1は本実施例によるシャッタ開閉機構の要部平面図、図2は更にその要部拡 大図であるが、一方のシャッタ羽根5は省略されている。 図において、コイルバネ10に代えてコイル状の羽根バネ12がガタ取り用の バネとして用いられており、その巻回部12aはシャッタ羽根6の支軸4にゆる く嵌合され、巻回部12aから延びる一端部12bは一方のシャッタ羽根6の外 周に掛け止めされ、又他端部12cは、二つのシャッタ羽根5,6の各スロット 5a,6aに嵌挿された駆動ピン8aに係止されている。 これによって、一対のシャッタ羽根5,6は羽根閉鎖方向に付勢されることに なる。 A preferred embodiment of the present invention will be described below with reference to FIGS. 1 and 2, but the same parts or members as those of the above-described conventional art will be designated by the same reference numerals and the description thereof will be omitted. FIG. 1 is a plan view of a main part of a shutter opening / closing mechanism according to this embodiment, and FIG. 2 is an enlarged view of the main part thereof, but one shutter blade 5 is omitted. In the figure, instead of the coil spring 10, a coiled blade spring 12 is used as a spring for removing backlash, and the winding portion 12a is loosely fitted to the support shaft 4 of the shutter blade 6, and the winding portion 12a. The one end 12b extending from the one end is hooked on the outer circumference of the one shutter blade 6, and the other end 12c is locked to the drive pin 8a fitted into the respective slots 5a and 6a of the two shutter blades 5 and 6. Has been done. As a result, the pair of shutter blades 5 and 6 are urged in the blade closing direction.

【0011】 本実施例は上述のように構成されているから、シャッタ羽根5,6の閉鎖状態 (実線図示)から開放作動させる場合、駆動モータ7を左旋(反時計方向の回動 )させると、一体に回動する開閉レバー8により駆動ピン8aも小判型孔2aの 範囲内で同一方向に回動して、シャッタ羽根5,6を開放作動させる。 この時、シャッタ羽根6の右旋に連動して羽根バネ12の一端部12bも右旋 するが、他端部12cは駆動ピン8aと一体に右旋方向に回動するため、結局羽 根バネ12は全体が巻回部12aを中心に時計方向に回動することになる。従っ て、両端部12b,12c間の角度はほとんど変化しないので、羽根バネ12の 付勢力はシャッタ羽根5,6の開口径に関わらず殆ど変化しないことになる。 又、シャッタ羽根5,6の閉鎖方向の作動時には、駆動ピン8aに押動されて シャッタ羽根6は左旋するが、羽根バネ12も巻回部12aを中心に反時計方向 に回転するため、結局その付勢力の大きさは殆ど変化しない。 このように、駆動ピン8aの回動に伴ってシャッタ羽根6が開閉作動する際、 羽根バネ12も連動して回動していくため、羽根バネ12の力量は変化せず、全 開状態、閉鎖状態であっても同様である。Since the present embodiment is configured as described above, when the shutter blades 5, 6 are opened from the closed state (shown by solid lines), the drive motor 7 is rotated counterclockwise (counterclockwise). The drive pin 8a is also rotated in the same direction within the oval hole 2a by the opening / closing lever 8 which is integrally rotated to open the shutter blades 5 and 6. At this time, the one end 12b of the blade spring 12 also rotates clockwise in conjunction with the clockwise rotation of the shutter blade 6, but the other end 12c rotates rightward together with the drive pin 8a, so that the blade spring is eventually rotated. The whole 12 rotates clockwise around the winding portion 12a. Therefore, since the angle between both ends 12b and 12c hardly changes, the biasing force of the blade spring 12 hardly changes regardless of the opening diameter of the shutter blades 5 and 6. Further, when the shutter blades 5 and 6 are actuated in the closing direction, the shutter blade 6 is rotated counterclockwise by being pushed by the drive pin 8a, but the blade spring 12 also rotates counterclockwise around the winding portion 12a. The magnitude of the biasing force hardly changes. In this way, when the shutter blade 6 is opened and closed according to the rotation of the drive pin 8a, the blade spring 12 also rotates in conjunction with it, so that the force of the blade spring 12 does not change, and the fully open state, The same is true in the closed state.

【0012】 上述のように本実施例は、シャッタ羽根5,6の回動位置に関わらず羽根バネ 12の力量をほぼ一定に保持することができるから、シャッタの開口径の大きさ に関わらずメカ遅れのバラツキが発生せず、露光量が正確且つ安定的である。又 、全開時と小絞り時における羽根バネ12の力量に変化がないので、バネ12の 力量を比較的大きく設定しておけば、小絞り時のシャッタ速度を速くすることが できる。更に、羽根バネ12の力量に変化がないため、バネ12による胴締めが 常に閉鎖状態と同一の状態に保持され、開閉作動時に羽根バネ12が外れること がなく且つ羽根駆動のための電力も一定のものでよい。しかも、羽根バネ12の 力量を適当に調整しておけば、全開状態で羽根に変形を来すような過大な負荷が かかることはなく、耐久性を向上できる。As described above, in the present embodiment, the force amount of the blade spring 12 can be kept substantially constant regardless of the rotational positions of the shutter blades 5 and 6, so that the aperture diameter of the shutter is not affected. The exposure amount is accurate and stable without causing mechanical delay variations. Further, since the force amount of the blade spring 12 does not change at the time of full opening and at the time of the small aperture, if the force amount of the spring 12 is set relatively large, the shutter speed at the time of the small aperture can be increased. Further, since the force of the blade spring 12 does not change, the body tightening by the spring 12 is always kept in the same state as the closed state, the blade spring 12 does not come off during the opening and closing operation, and the power for driving the blade is constant. Anything is fine. Moreover, if the force of the blade spring 12 is appropriately adjusted, the durability is improved without an excessive load that would deform the blade in the fully opened state.

【0013】 尚、上述の実施例では、羽根バネ12をシャッタ羽根6に掛けたが、他方のシ ャッタ羽根5に掛けるようにしてもよいことはいうまでもない。 又、羽根バネ12の荷重の付勢方向はシャッタ羽根の閉鎖方向に代えて開放方 向であってもよい。 尚、羽根バネ12は付勢部材を構成する。Although the blade spring 12 is hooked on the shutter blade 6 in the above embodiment, it goes without saying that it may be hooked on the other shutter blade 5. Further, the biasing direction of the load of the blade spring 12 may be the opening direction instead of the closing direction of the shutter blade. The blade spring 12 constitutes a biasing member.

【考案の効果】[Effect of the device]

上述のように本考案に係るカメラのシャッタ開閉機構は、付勢部材が回転可能 であると共にその両端がシャッタと開閉部材に係止されているから、シャッタの 作動時におけるガタを有効に防止できる他に、シャッタの開口径の大きさに関わ らず付勢部材の力量が変化しないので、メカ遅れのバラツキが発生せず、露光量 が正確且つ安定的である。又、全開時と小絞り時における付勢部材の力量に変化 がないから、小絞り時のシャッタ速度を速くすることができる。更に、付勢部材 による胴締めが常に羽根閉鎖状態と同一の状態に保持され、開閉作動時に付勢部 材が外れることがなく、羽根駆動のための電力も一定のものでよい。しかも、付 勢部材の力量を適当に調整しておけば、全開状態で羽根に過大な負荷がかかって 変形することもなく、耐久性を向上できる。 As described above, in the shutter opening / closing mechanism of the camera according to the present invention, since the biasing member is rotatable and both ends of the biasing member are locked by the shutter and the opening / closing member, it is possible to effectively prevent backlash when the shutter is operated. In addition, since the force amount of the biasing member does not change regardless of the opening diameter of the shutter, variation in mechanical delay does not occur, and the exposure amount is accurate and stable. Further, since there is no change in the force amount of the biasing member at the time of fully opening and at the time of small aperture, the shutter speed at the time of small aperture can be increased. Further, the body tightening by the biasing member is always kept in the same state as the blade closed state, the biasing member does not come off during the opening and closing operation, and the power for driving the blade may be constant. Moreover, if the force of the biasing member is appropriately adjusted, the blade is not deformed due to an excessive load in the fully opened state, and the durability can be improved.
