る。BACKGROUND ART Various cameras with built-in strobes have been proposed or put into practical use in which the light-emitting section of the built-in strobe device as described above is automatically extended from the storage position to the operating position during low-brightness photography that requires auxiliary light. There is.

手段が、実間昭54−27622号公報にて提案され、
よく知られている。 By the way, looking at the means for moving the light emitting part in the camera with a built-in strobe as described above, a normally open type electromagnet is used, and by energizing this electromagnet, this electromagnet attracts the lock release member, and the release member is released. A means for protruding the light emitting part from the storage position within the camera body to the operating position by operation was proposed in Jitsema No. 54-27622,
well known.

しかしながら、上記提案における発光部の移動
手段は、上述の如く常時釈放型の電磁石を用いて
おり、離反している係止解除部材を吸着するには
電力をたくさん消費してしまうという欠点を有し
ており実用的ではない。 However, the means for moving the light emitting part in the above proposal uses a constantly released electromagnet as described above, and has the disadvantage that it consumes a lot of power to attract the detached unlocking member. It is not practical.

一方、上記した如くの欠点を解決するものとし
て実開昭57−3228号公報に示された如くの発光部
の移動手段が提案されている。 On the other hand, in order to solve the above-mentioned drawbacks, a means for moving the light emitting part as disclosed in Japanese Utility Model Application Laid-Open No. 57-3228 has been proposed.

させるものである。 This proposal is a means of reducing power consumption by using a constantly attracting electromagnet.Simply stated, at high brightness when there is no need for the light emitting part to protrude, the light emitting part is biased in the protruding direction by spring force. The part is attracted by the magnetic force of a permanent magnet against the spring force and kept housed in the camera body, and at low brightness when it is necessary to make the light emitting part protrude, the part is wound around the permanent magnet in a direction that cancels out the magnetic force of the permanent magnet. The electromagnetic coil is excited to lose its attractive force, and the strobe light emitting part is caused to protrude by the spring force.

時計方向に回転する。 Figure 4 shows the light emitting unit moving means shown in the above proposal, and in the same figure, as a result of measuring the subject brightness by a photometric circuit (not shown), it is constantly attracted at low brightness times when the strobe device needs to emit light. type electromagnet 1
When the electromagnetic coil 1b is energized, the unlocking member 2, which had been attracted to the permanent magnet 1a,
Since the attraction by the permanent magnet 1a is released, the lock release member 2 is rotated counterclockwise by the biasing force of the spring 3.

除されることになる。 Then, the tip 2a of the unlocking member 2 pushes the tip of the locking member 4 to the right in the figure, and the locking member 4 also rotates counterclockwise against the biasing force of the spring 5. As a result, the locking portion 4b of the locking member 4 and the lock pin 7 provided on the guide plate 6 are released.

上記係止部４ｂとロツクピン７との係止が解除
されるとガイド板６はバネ９の付勢力により図の
上方に移動し、同時に発光部８も同方向に移動せ
しめられることになる。 When the engagement between the engagement portion 4b and the lock pin 7 is released, the guide plate 6 is moved upward in the drawing by the biasing force of the spring 9, and at the same time, the light emitting portion 8 is also moved in the same direction.

尚、上記発光部８の移動量は、ガイド板６に設

係によつて設定されることはいうまでもない。 It goes without saying that the amount of movement of the light emitting section 8 is determined by the relationship between the guide groove 6a provided in the guide plate 6 and the guide pin 10 projected from a fixed member (not shown). Nor.

の作用により時計方向に回転する。 Now, when the guide plate 6 and the light emitting part 8 are moved upward by the spring 9 as described above, the return member 11 is moved by the control member biased by the spring 13 so that its oblique end 11a contacts the lock pin 7 to the raised position. 12
Rotates clockwise due to the action of

この時、制御部材１２は図中の左方向に移動
し、先の常時吸着型電磁石１の電磁コイル１ｂへ
の通電を遮断する。 At this time, the control member 12 moves to the left in the figure and cuts off the current to the electromagnetic coil 1b of the constant attraction type electromagnet 1.

吸着され、元の状態に復帰することになる。 When the return member 11 rotates as described above, its tip 11b aligns with the tip 2 of the unlocking member 2.
Press a, and the unlocking member 2 moves clockwise.
That is, it is brought close to the permanent magnet 1a of the electromagnet 1 so as to be in contact with it. At this time, since the electromagnet 1 is de-energized by the movement of the control member 12, the unlocking member 2 is attracted to the permanent magnet 1a and returns to its original state.

以上の動作で一連の発光部８の突出動作が終了
するわけである。 With the above operation, the series of protruding operations of the light emitting section 8 is completed.

単に行なわれることになる。 To return the light emitting section 8 to its original state, if the light emitting section 8 is pushed down against the biasing forces of the springs 9, 5, and 13, the lock pin 7 will
Oblique end portions 4 of each of the locking member 4 and the return member 11
c, move while pressing on 11a, and lock part 4b.
It is clear from the drawing that the above-described return operation is engaged with the above-mentioned push-down operation.

以上述べたように、内蔵ストロボ装置の発光部
移動装置としては、常時釈放型あるいは常時吸着
型の電磁石を用いたものがよく知られている。 As described above, as a light emitting unit moving device for a built-in strobe device, one using a constantly open type or a constantly attracted type electromagnet is well known.

尚、モータを使用して発光部を移動する手段も

石を用いるものであり、従来例としての説明は省
略する。 Although means for moving the light emitting section using a motor are also known, the present invention uses an electromagnet as described above, and a description of the conventional example will be omitted.

考案が解決しようとする問題点 上述したように電磁石を用いた発光部の移動手

時吸着型のものが常時釈放型のものに比して有利
となることはいうまでもなく、本考案も常時吸着
型電磁石を用いたものである。Problems that the invention aims to solve As mentioned above, two types of means for moving the light emitting part using electromagnets were described, but as for electromagnets, the always-attracting type is more advantageous than the always-release type. Needless to say, the present invention also uses a constant attraction type electromagnet.

さて、上述した常時吸着型電磁石を用いた発光
部の移動手段は、電力消費の点で有利となるが、
その移動構成自体を詳細にみると、依然として下
記の如くの間題点を有している。 Now, the above-mentioned means of moving the light emitting part using the constant attraction type electromagnet is advantageous in terms of power consumption, but
If we look at the moving structure itself in detail, it still has the following problems.

まず、第４図に示した構成における発光部８の

の結果、駆動源となるバネ９の付勢力を強くする
必要がある。 First, considering the force necessary for the protruding operation of the light emitting part 8 in the configuration shown in FIG. Part 4
b, 11a, and therefore, it is necessary to consider the load on the protrusion movement due to such contact, as well as the movement load of the light emitting part 8 and the guide plate 6. As a result, the biasing force of the spring 9, which is the driving source, is reduced. need to be strengthened.

即ち、発光部８の突出完了時において係止部材
２を元の状態に戻すべく構成していることから、
発光部の突出動作は上記係止部材４および復帰部
材１１を付勢しているバネ５，１３の影響を受け
るわけであり、パネ９の付勢力は強く設定しなけ
ればならないわけである。 That is, since the locking member 2 is configured to return to its original state when the projection of the light emitting part 8 is completed,
The projecting operation of the light emitting part is influenced by the springs 5 and 13 that bias the locking member 4 and the return member 11, and the biasing force of the panel 9 must be set strongly.

このため、発光部８が受ける突出時の機械的衝
撃は大きく、発光部８内の閃光放電管がリード線
よりはずれたり、あるいは少しでも上記バネ９の
付勢力が弱くなると発光部８が所望の位置まで移
動しきらない場合が生じる恐れのある問題点を有
することになる。 For this reason, the mechanical shock that the light emitting part 8 receives when protruding is large, and if the flash discharge tube inside the light emitting part 8 becomes detached from the lead wire, or if the biasing force of the spring 9 weakens even a little, the light emitting part 8 will not move as desired. This poses a problem in that it may not be able to move completely to the desired position.

また、復帰部材１１による係止解除部材２の制
御動作がロツクピン７と当接する斜端部１１ａの
傾斜を利用して行なわれることから、発光部８の
移動ストロークを短かくしたい場合、当然上記傾
斜をきつくする必要がある。 Furthermore, since the control operation of the unlocking member 2 by the return member 11 is performed by utilizing the slope of the oblique end portion 11a that comes into contact with the lock pin 7, it is natural that when it is desired to shorten the movement stroke of the light emitting portion 8, the above-mentioned slope need to be tightened.

来装置はコンパクト化に極めて好ましいとは言え
ないわけである。 However, if the above-mentioned inclination is made steeper, the load during the reset operation of the return member 11, that is, the retracting operation of the light emitting section 8 becomes large.
In addition to the strong biasing force, the storage operation becomes troublesome, and the above-mentioned slope cannot be made too steep.In other words, the conventional device shown in FIG. 4 is not very suitable for compactness. That's why I can't say it.

る。Means for Solving the Problems Means for solving the problems of the above-mentioned conventional device in the present invention are a locking member that locks the projecting operation of the light emitting section that is always urged to project; Unlike conventional devices, the resetting operation of the drive piece of the constant attraction type electromagnet that controls the operation of the stop member is performed in conjunction with the retracting operation of the light emitting section.

態に保持しておく構成を形成したものである。 That is, the present invention includes a reset member that slides and rotates in response to the protruding and retracting operations of the light emitting part, and the reset member controls the operation of the driving piece, and the locking member and the driving piece are connected to the light emitting part. The structure is such that it is maintained in the state set at the time of the ejecting operation unless the retracting operation is performed.

の付勢力を弱くできることになるわけである。Operation The device for moving a strobe light emitting part according to the present invention operates by the means described above without returning the locking member and the driving piece to their original states, that is, the state when they are not protruding, when the light emitting part is projected. Therefore, the force required to project the light emitting part can be determined by simply considering the moving load of the light emitting part, and the biasing force of the spring for projecting the light emitting part can be weakened.

になる。 Reference numeral 18 denotes a reset control member which is slidably and rotatably mounted on the board 17 via its own guide groove 18a and the cam groove 17a of the board 17 with a fixing pin 19, and its control arm 18b is connected to the guide groove 17a of the board 17. It is formed to have an elastic force with respect to the main body portion provided with the groove 18a, and its tip 18c comes into contact with a cam surface 14d of the driving piece 14 when the light emitting part 8 is stored, which will be described later. The control protrusion 6c of the guide plate 6 comes into contact with the light emitting part 8, which will be described later, when the light emitting part 8 is projected or retracted, thereby controlling its own movement.

さて、以下、上記如くの構成からなる本考案に

作状態における正面図を示した第３図イ〜ホを参
照して説明する。 Now, the operation of the light emitting unit moving device according to the present invention having the above-mentioned configuration will be explained with reference to FIGS. 3A to 3E showing front views in arbitrary operating states.

まず、定常状態、即ち発光部８が図示はしてい

述べる。 First, a steady state, that is, a state in which the light emitting section 8 is housed in a camera body (not shown) will be described.

ている。 The steady state in the moving device according to the present invention is formed by the one end 16b of the locking lever 16 engaging with the locking protrusion 6b of the guide plate 6 and fixing the guide plate 6 against the biasing force of the spring 9. Needless to say, the situation shown in FIG. 1 applies.

成しているわけである。 To explain in more detail with reference to the front view of FIG. 3A, which corresponds to the state of FIG. As a result, one end 16a of the locking member 16 can be moved to the illustrated position by the control pin 21 formed at the other end 14c, and this action causes the locking lever 16 to be locked with the one end 16b. This means that the engagement with the protrusion 6b is completed.

さて、今、第４図に示した従来装置同様、被写

１５の付勢力により反時計方向に回動することに
なる。 Now, like the conventional device shown in FIG. 4, when it is determined that a strobe device is necessary as a result of measuring the subject brightness and the constant attraction type electromagnet 1 is energized, the attraction of the drive piece 14 is released and the drive piece 14 is released. The piece 14 is rotated counterclockwise by the biasing force of the spring 15.

ちガイド板６に設けられた発光部８が上方に移動
し始めることになる。 When the driving piece 14 rotates, the one end 16 of the locking lever 16 is controlled by the control pin 21 of the one end 14c.
Since a is pressed, the locking lever 16 similarly rotates counterclockwise against the biasing force of the spring 22, and the engagement between the one end 16b of the locking lever 16 and the locking protrusion 6b described above is released. Therefore, the guide plate 6 moves upward by the biasing force of the spring 9, that is, the light emitting section 8 provided on the guide plate 6 begins to move upward.

の状態になされることになる。 On the other hand, when the guide plate 6 begins to move upward, the control protrusion 6c applies a counterclockwise rotational force to the reset control member 18 through its one end 18d against the urging force of the spring 20 due to its inclined portion. Therefore, the reset control member 18 is operated as shown in FIG. It will be brought to such a state.

第３図ハに示した如くの状態となり安定する。 Then, when the guide plate 6 has moved all the way to the top,
One end 18d completely overcomes the control protrusion 6c,
Therefore, the reset control member 18 is controlled by the biasing force of the spring 20, and the entire device becomes stable as shown in FIG. 3C.

る。 It goes without saying that the state shown in FIG.
The driving piece 14 is always held at a position away from the attraction type electromagnet 1, and the locking lever 16 is also held in a state in which it cannot lock the guide plate 6. Further, the tip end 18c of the control arm 18b of the reset control member 18 is stabilized in a state in which it is brought into contact with the side slope 14d of the drive piece 14 by the biasing force of the spring 15.

Considering the force required to project the light emitting part 8 as described above, other than the force necessary to move the guide plate 6 and the light emitting part 8, it is only necessary to consider the force for rotating the reset control member 18, which is a small force. As a result, spring 9
This means that a material with weak elasticity can be used.

次に、発光部８の収納動作であるが、かかる動
作は、発光部８を手動にて下方へ押し下げること
によつて行なわれる。 Next, the operation of storing the light emitting section 8 is carried out by manually pushing the light emitting section 8 downward.

とになる。 When the light emitting section 8 is pushed down against the biasing force of the spring 9, the control protrusion 6c of the guide plate 6 comes into contact with one end 18d of the reset control member 18, and when it is pushed down further, the reset occurs as shown in FIG. 3D. The cam pin 18e of the control member 18 is connected to the cam groove 1 of the board 17.
This results in a state where it comes into contact with the lower end of 7a. At this time, the reset control member 18
The side slope 14 of the drive piece 14 at the tip 18c of b
d against the biasing force of the spring 15, and therefore,
As is clear from this figure, the drive piece 14 is rotated slightly clockwise by the downward movement of the light emitting section 8 to the state shown in FIG. 3D.

よる下方向への力供給によつてカムピン１８ｅと

められることになる。 If the light emitting part 8 is further pushed down from the state shown in FIG. It is rotated clockwise due to the relationship with the groove 17a.

当然のことながら、その回動力が制御腕１８ｂの
先端部１８ｃを介して駆動片１４にも供給される
ことになり、従つて駆動片１４も第３図ニの状態
からさらに時計方向に回動することになる。 Naturally, when the reset control member 18 rotates clockwise, the rotational force is also supplied to the drive piece 14 via the tip 18c of the control arm 18b, and therefore the drive piece 14 also rotates in the third direction. It will rotate further clockwise from the state shown in Figure D.

吸着されることになる。 Therefore, it is possible to control the energization of the constantly attracting electromagnet 1 by using, for example, a timer means that operates according to the measurement result of the subject brightness so that it can be terminated after the projecting operation of the light emitting section 8. In the state shown in FIG. 3E described above, one end portion 14b of the drive piece 14 is attracted to the permanent magnet 1a via the iron piece member 23.

されることになる。 On the other hand, if the drive piece 14 performs the rotation operation as described above by pressing down the light emitting part 8, the one end 14c
The locking lever 16, which is controlled by the control pin 21, naturally responds to the above operation, and is rotated clockwise by the biasing force of the spring 22 from the state shown in FIG. 3C, as shown in FIGS. 3D and 3E. As a result, the guide plate 6 can be locked in the state shown in FIG. 3E, similar to the state shown in FIGS. 1 and 3A.

ことになる。 Finally, the light emitting section 8 is further removed from the state shown in FIG.
When the reset control member 18 is pushed down, the one end 18d of the reset control member 18 comes into contact with the slope of the control protrusion 6c, and is gradually rotated counterclockwise by the biasing force of the spring 20, that is, as shown in FIG. 3A. The locking lever 16 rotates to return to its original state, and the locking lever 16 also rotates at its one end 1.
6b comes into contact with the sloped surface of the locking projection 6b, so that, like the reset control member 18, it is rotated counterclockwise against the biasing force of the spring 22.

することになるわけである。 When the one end 16b exceeds the apex of the locking protrusion 6b, the locking lever 16 is rotated clockwise by the biasing force of the spring 22, and the locking protrusion shown in FIG. 1 or 3A is rotated clockwise. This results in the formation of an engaged state with 6c.

以上が発光部８の収納動作であるが、ここでか
かる収納動作時に必要な力を考えてみると、バネ
９，１５，２０の付勢力を越える力が必要となる
ことはいうまでもない。 The above is the storage operation of the light emitting section 8, but if we consider the force required for such storage operation, it goes without saying that a force exceeding the biasing force of the springs 9, 15, and 20 is required.

移動装置における発光部収納動作時に必要な力
は、従来装置のように大きくなることはない。 However, as described above, the spring 9 described above can have a weaker biasing force than the spring 9 in the conventional device, and the force opposing the biasing force of the spring 15 can also be applied in the direction opposite to the biasing force of the spring 15. Of course, the spring 20 does not cause any movement of the reset control lever 18 by its own biasing force; it is sufficient to simply pull the reset control lever 18 upward at all times. Therefore, a spring with a small biasing force can be used, and the force required during the light emitting unit retracting operation in the light emitting unit moving device according to the present invention does not become as large as in the conventional device.

ている。Effects of the Invention As described above, the light emitting unit moving device according to the present invention is capable of constantly adsorbing the locking release operation of the locking means that locks the light emitting unit, which is always biased in the protruding direction, in the storage position. This is done by energizing the electromagnet, and a reset control member that slides and rotates when the light emitting part is retracted is used to return the light emitting part to a state in which it can be locked again. It is not used for the above-mentioned return of the locking means, and therefore, the biasing force of the spring that biases the light emitting part to protrude can be set weakly, and it is easy to prevent the lead wire from slipping and adjust the biasing force of the spring. It has the effect of
