Description

本発明は、カメラのアクセサリーシューに対して着脱可能なカメラ用アクセサリーに関する。 The present invention relates to a camera accessory that can be attached to and detached from an accessory shoe of a camera.

特許文献１はアクセサリーシューを有するカメラと、アクセサリーシューに着脱可能なストロボと、を開示している。
アクセサリーシューは前後両面及び上面の一部が開口したものであり、その内部空間の底面にはカメラ内に設けた電源回路と接続する金属製のカメラ側端子が設けてある。
ストロボの下端部にはシュー（取付足）が設けてある。このシューは、アクセサリーシューの内部空間に対して挿脱可能なベース（支持部材）と、ベースの底面に固定したシュー金具と、ベースに支持しかつシュー金具の下端面から下方に突出した金属製の端子と、ベースに対して上下方向の軸線周りに回転しながら上下方向にスライド可能なロック部材（固定リング）と、を備えている。
さらにシューは、ロック部材の回転動作に伴って、端子をベースに対して水平方向に対してスライドさせるスライド機構を備えている。ロック部材を初期位置からロック位置側へ回転させると、ロック部材は徐々にベースに対して接近し（下方へ移動し）、ロック位置まで移動したときにベースに対して最も接近する。 Patent Document 1 discloses a camera having an accessory shoe and a strobe detachable from the accessory shoe.
The accessory shoe has both front and rear surfaces and a part of the upper surface opened, and a metal camera side terminal connected to a power circuit provided in the camera is provided on the bottom surface of the internal space.
A shoe (mounting foot) is provided at the lower end of the strobe. This shoe is made of a base (support member) that can be inserted into and removed from the interior space of the accessory shoe, a shoe fitting fixed to the bottom surface of the base, and a metal that supports the base and protrudes downward from the lower end surface of the shoe fitting. And a lock member (fixing ring) that is slidable in the vertical direction while rotating about the vertical axis with respect to the base.
Furthermore, the shoe includes a slide mechanism that slides the terminal in the horizontal direction with respect to the base as the lock member rotates. When the lock member is rotated from the initial position to the lock position side, the lock member gradually approaches the base (moves downward), and approaches the base most when it moves to the lock position.

ストロボをカメラに対して装着するには、アクセサリーシューの上面開口からストロボの大部分をアクセサリーシューの上方へ突出させながら、ロック部材を初期位置に位置させたシューのシュー金具及び端子をアクセサリーシューの後面からアクセサリーシューの内部空間に挿入する。するとベースの上面がアクセサリーシューの天井面に接触しかつ端子がカメラ側端子に接触する。
この状態でロック部材をロック位置側へ回転させると、端子がカメラ側端子に対して水平方向にスライドするので、端子やカメラ側端子の表面に付着していた酸化膜や汚れが除去される。そのため端子とカメラ側端子が確実に導通可能となる。
そしてロック部材がロック位置まで移動すると、ロック部材がアクセサリーシューの上面に対して上方から接触する。即ち、シュー金具とロック部材がアクセサリーシューを上下方向から挟持するので、ストロボがアクセサリーシュー（カメラ）に対して確実に固定される。
またロック部材を初期位置に戻した上で、シュー金具及び端子をアクセサリーシューに対して水平方向へスライドさせれば、ストロボ（シュー金具及び端子）をアクセサリーシューから取り外すことが可能である。 To attach the strobe to the camera, the shoe bracket and terminal of the shoe with the lock member positioned at the initial position are inserted into the accessory shoe while the majority of the strobe protrudes from the top opening of the accessory shoe above the accessory shoe. Insert into the interior space of the accessory shoe from the rear. Then, the upper surface of the base contacts the ceiling surface of the accessory shoe, and the terminal contacts the camera side terminal.
When the lock member is rotated to the lock position side in this state, the terminal slides in the horizontal direction with respect to the camera side terminal, so that the oxide film and dirt adhering to the surface of the terminal and the camera side terminal are removed. Therefore, the terminal and the camera side terminal can be reliably connected.
When the lock member moves to the lock position, the lock member comes into contact with the upper surface of the accessory shoe from above. That is, since the shoe fitting and the lock member clamp the accessory shoe from above and below, the strobe is securely fixed to the accessory shoe (camera).
Further, when the shoe member and the terminal are slid in the horizontal direction with respect to the accessory shoe after the lock member is returned to the initial position, the strobe (the shoe member and the terminal) can be removed from the accessory shoe.

特許文献１では、シュー金具及び端子をアクセサリーシューの後面からアクセサリーシューの内部空間に挿入したときにシュー金具の上面がアクセサリーシューの天井面に接触しかつ端子がカメラ側端子に接触する程度に、シューの端子がシュー金具の下面から下方に（常に）突出している。
そのためシュー金具及び端子のアクセサリーシューに対する上下位置を正確に合わせないと、シュー金具及び端子をアクセサリーシューの内部空間に対して挿入できない。即ち、ストロボのアクセサリーシューに対する装着が容易ではない。
さらにストロボ（シュー金具及び端子）をアクセサリーシューから取り外す際には、シュー金具及び端子とアクセサリーシューの内面（及びカメラ側端子）との間で摩擦抵抗が発生するので、ストロボのアクセサリーシューに対する取り外しも容易ではない。 In Patent Document 1, when the shoe fitting and the terminal are inserted from the rear surface of the accessory shoe into the interior space of the accessory shoe, the upper surface of the shoe fitting is in contact with the ceiling surface of the accessory shoe and the terminal is in contact with the camera side terminal. The shoe terminal protrudes downward (always) from the lower surface of the shoe fitting.
Therefore, the shoe fitting and the terminal cannot be inserted into the interior space of the accessory shoe unless the vertical positions of the shoe fitting and the terminal with respect to the accessory shoe are precisely aligned. That is, it is not easy to attach the strobe to the accessory shoe.
Furthermore, when removing the strobe (shoe bracket and terminal) from the accessory shoe, frictional resistance is generated between the shoe bracket and terminal and the inner surface of the accessory shoe (and the terminal on the camera side). It's not easy.

シュー２１は大きな構成要素として本体取付部２２、ロック部材２７（ロック機構、ロック部材第一構成部２８、ロック部材第二構成部６７）、端子ユニット３８、ベース７８、及びグランド接点部材９２を備えている。
樹脂等の絶縁性材料からなる本体取付部２２の中心部には本体取付部２２を上下方向に貫通する断面円形の中央貫通孔２３が形成してある。本体取付部２２の下面は円形のロック部材支持面２４により構成してあり、ロック部材支持面２４の下面には中央貫通孔２３を中心とする円弧形状をなす一対の第一カム溝形成用突起２５（第一カム溝）が突設してある。さらに第一カム溝形成用突起２５の下端面は二つの面により形成してある（なお、第一カム溝形成用突起２５の下端面に、この二つの面に加えて他の面を形成してもよい）。即ち、第一カム溝形成用突起２５の下端面は、本体取付部２２を上方から見たときに（中央貫通孔２３を中心としかつ第一カム溝形成用突起２５が位置する円周の）時計方向側に位置する水平面からなるピン突出許容カム面２５ａと、反時計方向側に位置しかつピン突出許容カム面２５ａ（水平面）に対して傾斜するピン突出量調整用カム面２５ｂとを有している。ピン突出量調整用カム面２５ｂは時計方向側から反時計方向側に向かうに従って徐々に下方へ向かう傾斜面である。さらに本体取付部２２には、本体取付部２２を上下方向に貫通する四つのボルト用貫通孔２６が形成してある。 Next, the structure of the strobe 20 (camera accessory) will be described.
The strobe 20 is integrally provided with a strobe main body (not shown) having a light emitting portion and a shoe 21 protruding downward from a lower portion of the strobe main body.
The shoe 21 includes a main body attachment portion 22, a lock member 27 (lock mechanism, lock member first component 28, lock member second component 67), a terminal unit 38, a base 78, and a ground contact member 92 as large components. ing.
A central through hole 23 having a circular cross section that penetrates the main body attachment portion 22 in the vertical direction is formed at the center of the main body attachment portion 22 made of an insulating material such as resin. The lower surface of the main body mounting portion 22 is constituted by a circular lock member support surface 24, and a pair of first cam groove forming protrusions having an arc shape centering on the central through hole 23 on the lower surface of the lock member support surface 24. 25 (first cam groove) is projected. Further, the lower end surface of the first cam groove forming projection 25 is formed by two surfaces (in addition to these two surfaces, another surface is formed on the lower end surface of the first cam groove forming projection 25. May be) In other words, the lower end surface of the first cam groove forming projection 25 is viewed from above the body mounting portion 22 (the circumference around the central through hole 23 and the first cam groove forming projection 25 is located). There is a pin protrusion allowable cam surface 25a made of a horizontal plane located on the clockwise side, and a pin protrusion amount adjusting cam surface 25b which is positioned on the counterclockwise side and inclined with respect to the pin protrusion allowable cam surface 25a (horizontal plane). doing. The pin protrusion amount adjusting cam surface 25b is an inclined surface that gradually goes downward as it goes from the clockwise direction to the counterclockwise direction. Further, four bolt through holes 26 are formed in the main body attaching portion 22 so as to penetrate the main body attaching portion 22 in the vertical direction.

略円環状をなしかつ樹脂等の絶縁性材料からなるロック部材第一構成部２８の外周面には摘み部２９が突設してある。ロック部材第一構成部２８の中心部には第一カム溝形成用突起２５（及び中央貫通孔２３）と同軸をなす断面円形の貫通孔が形成してある。この貫通孔の内径は二段階で変化している。即ち、ロック部材第一構成部２８の上部を構成する環状突部３０の内周面である回転支持孔３０ａは、ロック部材第一構成部２８の下部の内周面より小径かつ第一カム溝形成用突起２５の外周面と略同径である。ロック部材第一構成部２８は、環状突部３０の回転支持孔３０ａに対して一対の第一カム溝形成用突起２５の外周面を回転可能に接触（嵌合）することにより、一対の第一カム溝形成用突起２５に対して回転可能に支持してある。環状突部３０の内周面の互いに１８０°離間した二カ所には第一カムフォロア３１が内周側に向けて突設してある。さらに環状突部３０の内周面の各第一カムフォロア３１と約９０°離間した二カ所には第二カム溝３２が凹設してある。図５、図７等に示すように第二カム溝３２は環状突部３０の周方向に沿って延びる溝であり、その下面は開放している。さらに第二カム溝３２の上端面は二つの傾斜面により形成してある。即ち、第二カム溝３２の上端面は、ロック部材第一構成部２８を上方から見たときに（ロック部材第一構成部２８の中心軸を中心としかつ第二カム溝３２が位置する円周の）反時計方向側に位置するピン突出用カム面３３と、時計方向側に位置するロック用カム面３４とを有している。ピン突出用カム面３３は反時計方向側から時計方向側に向かうに従って徐々に下方へ向かう傾斜面であり、ロック用カム面３４は反時計方向側から時計方向側に向かうに従って徐々に上方へ向かいかつ傾斜角がピン突出用カム面３３より緩い傾斜面である。環状突部３０の下面には四つの嵌合ピン３５が下向きに突設してある。さらに環状突部３０の下面には４つの雌ネジ孔３６が穿設してある。 A knob portion 29 projects from the outer peripheral surface of the lock member first component portion 28 which is substantially annular and made of an insulating material such as resin. A through hole having a circular cross section that is coaxial with the first cam groove forming protrusion 25 (and the central through hole 23) is formed at the center of the lock member first component 28. The inner diameter of the through hole changes in two steps. That is, the rotation support hole 30a, which is the inner peripheral surface of the annular protrusion 30 constituting the upper part of the lock member first component 28, has a smaller diameter than the inner peripheral surface of the lower part of the lock member first component 28 and the first cam groove. The diameter is substantially the same as the outer peripheral surface of the forming projection 25. The lock member first component portion 28 is rotatably contacted (fitted) with the outer peripheral surfaces of the pair of first cam groove forming protrusions 25 with respect to the rotation support hole 30a of the annular protrusion 30. A cam groove forming projection 25 is rotatably supported. First cam followers 31 project toward the inner peripheral side at two positions spaced apart from each other by 180 ° on the inner peripheral surface of the annular protrusion 30. Further, the second cam grooves 32 are recessed at two locations on the inner peripheral surface of the annular protrusion 30 that are separated from each of the first cam followers 31 by about 90 °. As shown in FIG. 5, FIG. 7, etc., the second cam groove 32 is a groove extending along the circumferential direction of the annular protrusion 30, and its lower surface is open. Furthermore, the upper end surface of the second cam groove 32 is formed by two inclined surfaces. In other words, the upper end surface of the second cam groove 32 is a circle when the lock member first component portion 28 is viewed from above (a center axis of the lock member first component portion 28 and the second cam groove 32 is located). It has a pin protruding cam surface 33 located on the counterclockwise side of the circumference and a locking cam surface 34 located on the clockwise side. The pin protruding cam surface 33 is an inclined surface that gradually decreases downward from the counterclockwise direction toward the clockwise direction, and the locking cam surface 34 gradually increases upward from the counterclockwise direction toward the clockwise direction. Further, the inclined surface is an inclined surface that is looser than the pin protruding cam surface 33. Four fitting pins 35 protrude downward from the lower surface of the annular protrusion 30. Further, four female screw holes 36 are formed in the lower surface of the annular protrusion 30.

The terminal unit 38 includes a contact board 39, a terminal support member 42, a drip-proof member 53, a terminal 55, a lock pin 59, a compression coil spring 62, and a bolt 64 as large components.
The metal and disk-shaped contact board 39 is provided with two bolt holes 40 and two fixing holes 41.
A terminal support member 42 made of an insulating material such as a resin is positioned directly below the bolt hole 40. The upper half portion of the terminal support member 42 is constituted by a contact board 39 and a circular portion 43 having a substantially circular cross section, and the lower half portion of the terminal support member 42 is constituted by a non-circular portion 44 having a substantially rectangular cross section. A pair of fixing pins 45 project upward from the upper surface of the circular portion 43, and a pair of female screw holes 46 are formed. Further, four terminal receiving holes 48 and one lock pin receiving hole 49 are formed on the upper surface of the circular portion 43, both penetrating the terminal support member 42 in the vertical direction. As shown in FIGS. 9 to 11, the terminal receiving hole 48 has an inner diameter that changes in two stages. That is, the terminal receiving hole 48 has a small-diameter lower end portion 48a constituting the lower end portion thereof, and a large-diameter portion 48b larger in diameter than the small-diameter lower end portion 48a constituting a portion located above the small-diameter lower end portion 48a. Yes. Although not shown, the lock pin receiving hole 49 has the same structure as the terminal receiving hole 48, and has a small-diameter lower end portion and a large-diameter portion larger in diameter than the small-diameter lower end portion. Further, support protrusions 50 are integrally projected at two positions on the outer peripheral surface of the circular portion 43 that are separated by 180 °. A cylindrical second cam follower 51 protrudes in a fixed state on the front end surface of each support protrusion 50.

非円形部４４の下端面には、非円形部４４と略同じ断面形状をなす防滴部材５３が固着してある。防滴部材５３は弾性を有する柔軟な材料（例えばスポンジ）により構成したものである。防滴部材５３には各端子受容孔４８の小径下端部４８ａとロックピン受容孔４９の小径下端部とそれぞれ対応する五つの挿通用孔５４が穿設してある。
端子支持部材４２の各端子受容孔４８とロックピン受容孔４９には共に金属製の略円柱状部材である端子５５とロックピン５９が上方からそれぞれ挿入してある。端子５５は、その上部を構成する大径被支持部５６と、その下部を構成しかつ大径被支持部５６より小径の突出部５７と、を一体的に備えている。ロックピン５９は、その上部を構成する大径被支持部６０と、その下部を構成しかつ大径被支持部６０より小径の突出部６１と、を一体的に備えている。端子５５は、その突出部５７が小径下端部４８ａに遊嵌しかつ大径被支持部５６が大径部４８ｂに遊嵌する態様で各端子受容孔４８に上下動可能に挿入してある（図９−図１１参照。大径部４８ｂの底部には止水用Ｏリングが設けてある）。大径被支持部５６の外径が小径下端部４８ａより大きいので、端子５５は大径被支持部５６の下面が大径部４８ｂの底面を超えて端子支持部材４２に対して下方へ移動することはない。一方、ロックピン５９は、その突出部６１が上記小径下端部に遊嵌しかつ大径被支持部６０が大径部に遊嵌する態様で各ロックピン受容孔４９に上下動可能に挿入してある（大径部の底部にも止水用Ｏリングが設けてある）。端子５５と同様に大径被支持部６０の外径が小径下端部より大きいので、ロックピン５９は大径被支持部６０の下面が大径部の底面を超えて端子支持部材４２に対して下方へ移動することはない。 A drip-proof member 53 having substantially the same cross-sectional shape as the non-circular portion 44 is fixed to the lower end surface of the non-circular portion 44. The drip-proof member 53 is made of a flexible material having elasticity (for example, sponge). The drip-proof member 53 has five insertion holes 54 corresponding to the small-diameter lower end portions 48a of the terminal receiving holes 48 and the small-diameter lower end portions of the lock pin receiving holes 49, respectively.
Both terminal receiving holes 48 and lock pin receiving holes 49 of the terminal support member 42 are respectively inserted with terminals 55 and lock pins 59 which are substantially cylindrical members made of metal from above. The terminal 55 is integrally provided with a large-diameter supported portion 56 that constitutes the upper portion thereof, and a protruding portion 57 that constitutes the lower portion thereof and has a smaller diameter than the large-diameter supported portion 56. The lock pin 59 is integrally provided with a large-diameter supported portion 60 that constitutes the upper portion thereof, and a protruding portion 61 that constitutes the lower portion thereof and has a smaller diameter than the large-diameter supported portion 60. The terminal 55 is inserted into each terminal receiving hole 48 so as to be vertically movable in such a manner that the protruding portion 57 is loosely fitted to the small diameter lower end portion 48a and the large diameter supported portion 56 is loosely fitted to the large diameter portion 48b ( 9 to 11. A water stop O-ring is provided at the bottom of the large diameter portion 48b). Since the outer diameter of the large-diameter supported portion 56 is larger than the small-diameter lower end portion 48a, the terminal 55 moves downward with respect to the terminal support member 42 with the lower surface of the large-diameter supported portion 56 exceeding the bottom surface of the large-diameter portion 48b. There is nothing. On the other hand, the lock pin 59 is inserted into each lock pin receiving hole 49 so that the protrusion 61 is loosely fitted to the lower end of the small diameter and the large diameter supported part 60 is loosely fitted to the large diameter. (O-ring for water stop is also provided at the bottom of the large diameter part). Like the terminal 55, the outer diameter of the large-diameter supported portion 60 is larger than the lower end portion of the small-diameter, so that the lock pin 59 has a lower surface of the large-diameter supported portion 60 beyond the bottom surface of the large-diameter portion. It does not move downward.

Further, a pair of fixing pins 45 of the circular portion 43 are fitted into the pair of fixing holes 41 of the contact board 39 and a pair of bolts 64 inserted from above into the bolt holes 40 of the contact board 39 are paired. Therefore, the contact state between the lower surface of the contact board 39 and the upper surface of the circular portion 43 (terminal support member 42) is maintained. As a result, since the terminal 55 is always urged downward by the corresponding compression coil spring 62, when the upward force is not exerted on the terminal 55, the lower end surface of the large-diameter supported portion 56 of the terminal 55 corresponds ( The protruding portion 57 protrudes downward from the lower end surface of the drip-proof member 53 through the insertion hole 54 and abuts against the water stop O-ring (provided at the bottom of the large diameter portion 48 b of the terminal receiving hole 48). Similarly, since the lock pin 59 is always urged downward by the corresponding compression coil spring 62, when the upward force is not exerted on the lock pin 59, the lower end surface of the large-diameter supported portion of the lock pin 59 corresponds. The protrusion 61 protrudes downward from the lower end surface of the drip-proof member 53 through the insertion hole 54 and abuts against the water-stop O-ring (provided at the bottom of the large-diameter portion of the lock pin receiving hole 49). .

さらに固定接続部７９の外周面には、金属製の弾性部材であるグランド接点部材９２が装着してある。このグランド接点部材９２は、ストロボ本体内に設けたグランド端子（図示略）と中間部材（導電性部材）を介して接続している。 The lower end of the shoe 21 is constituted by a base 78 made of an insulating material such as resin.
The upper portion of the base 78 is constituted by a fixed connection portion 79 having a substantially circular cross section, and the lower portion of the base 78 is constituted by an attachment portion 80 (lock mechanism) having a substantially rectangular shape in plan view.
The fixed connection portion 79 is formed with a pair of slits 82 that are separated from each other by 180 ° in the circumferential direction. Further, four female screw holes 83 are formed in the upper surface of the fixed connection portion 79. Further, a pair of first cam grooves 85 are provided at two positions spaced apart by about 180 ° in the circumferential direction of the outer peripheral surface of the fixed connection portion 79. As shown in FIGS. 5 and 7, the first cam groove 85 is a groove extending along the circumferential direction of the fixed connection portion 79, and the upper surface thereof is open. Further, the bottom surface of the first cam groove 85 is formed by two surfaces.

以上説明したように本体取付部２２及びベース７８とロック部材２７の間には第一カム溝形成用突起２５及び第一カム溝８５と第一カムフォロア３１を備える第一カム機構（ロック部材移動機構）が設けてあり、ロック部材２７（ロック部材第一構成部２８及びロック部材第二構成部６７）と端子支持部材４２（端子ユニット３８）の間には第二カム溝３２及び第二カム溝形成用突起７０と第二カムフォロア５１を備える第二カム機構（端子移動機構）が設けてある。そして、この第一カム機構（ロック部材移動機構）と第二カム機構（端子移動機構）を備える移動機構の働きによって、ロック部材２７と端子ユニット３８は本体取付部２２及びベース７８に対して以下のように相対移動する。 As described above, the first cam mechanism (lock member moving mechanism) including the first cam groove forming projection 25, the first cam groove 85, and the first cam follower 31 between the main body attaching portion 22 and the base 78 and the lock member 27. ) Between the lock member 27 (the lock member first component 28 and the lock member second component 67) and the terminal support member 42 (terminal unit 38). A second cam mechanism (terminal moving mechanism) including the forming protrusion 70 and the second cam follower 51 is provided. The lock member 27 and the terminal unit 38 are connected to the main body mounting portion 22 and the base 78 by the action of the moving mechanism including the first cam mechanism (locking member moving mechanism) and the second cam mechanism (terminal moving mechanism). Move relative to each other.

ロック部材２７（ロック部材第一構成部２８及びロック部材第二構成部６７）が図１、図２、及び図９に示す最大離間位置に位置するとき、ロック部材２７が取付部８０に対して上方へ最大限離間し、ロック部材２７と取付部８０との上下間隔がアクセサリーシュー１２の被挟持部１５の厚み（上下寸法）より大きくなる。このときロック部材２７（ロック部材第一構成部２８）の一対の第一カムフォロア３１は第一カム溝８５の時計方向側端部に係合（ピン突出許容カム面２５ａとピン突出許容カム面８６の時計方向側端部と係合）する（図８の符号３１Ａ参照）。また、端子ユニット３８の一対の第二カムフォロア５１は第二カム溝３２の反時計方向側端部に係合（ピン突出用カム面３３とピン突出用カム面７１の反時計方向側端部と係合）する（図７（ｂ）の符号５１Ａ参照）。端子支持部材４２及び防滴部材５３が非円形貫通孔８９内に位置するので、端子ユニット３８のベース７８（本体取付部２２）に対する相対回転は規制されており、端子ユニット３８はベース７８（本体取付部２２）に対して上下動のみ許容されている。さらに端子５５の突出部５７及びロックピン５９の突出部（下端部）は、防滴部材５３の対応する挿通用孔５４内に位置し（防滴部材５３の下端面から下方に突出せず）かつ取付部８０の下端面より上方に位置する（図９参照。但しロックピン５９は図示略）。さらに防滴部材５３の下面も取付部８０の下端面より上方に位置する（図９−図１１では防滴部材５３の図示を省略している）。 When the lock member 27 (the lock member first component 28 and the lock member second component 67) is located at the maximum separation position shown in FIGS. The distance between the lock member 27 and the attachment portion 80 is greater than the thickness of the sandwiched portion 15 (vertical dimension) of the accessory shoe 12. At this time, the pair of first cam followers 31 of the lock member 27 (lock member first component portion 28) is engaged with the clockwise end of the first cam groove 85 (the pin protrusion allowable cam surface 25a and the pin protrusion allowable cam surface 86). (See reference numeral 31A in FIG. 8). Further, the pair of second cam followers 51 of the terminal unit 38 are engaged with the counterclockwise end portions of the second cam groove 32 (the counterclockwise end portions of the pin protruding cam surface 33 and the pin protruding cam surface 71). (See reference numeral 51A in FIG. 7B). Since the terminal support member 42 and the drip-proof member 53 are located in the non-circular through hole 89, the relative rotation of the terminal unit 38 with respect to the base 78 (main body mounting portion 22) is restricted, and the terminal unit 38 is controlled by the base 78 (main body Only vertical movement is allowed with respect to the mounting part 22). Further, the protruding portion 57 of the terminal 55 and the protruding portion (lower end portion) of the lock pin 59 are located in the corresponding insertion hole 54 of the drip-proof member 53 (does not protrude downward from the lower end surface of the drip-proof member 53). And it is located above the lower end surface of the attaching part 80 (refer FIG. 9 but the lock pin 59 is abbreviate | omitting illustration). Further, the lower surface of the drip-proof member 53 is also located above the lower end surface of the mounting portion 80 (the drip-proof member 53 is not shown in FIGS. 9 to 11).

摘み部２９を利用しながら最大離間位置に位置するロック部材２７を平面視で反時計方向に回転させると、ロック部材２７が図１０に示す中間位置まで回転する。ロック部材２７が最大離間位置から中間位置まで回転するとき、ロック部材２７の一対の第一カムフォロア３１は第一カム溝８５の中間部に係合（ピン突出許容カム面２５ａとピン突出許容カム面８６の反時計方向側端部と係合）する（図８の符号３１Ｂ参照）。上記したようにピン突出許容カム面２５ａとピン突出許容カム面８６は水平面により構成したカム面であるため、ロック部材２７のベース７８に対する上下方向位置は最大離間位置のときと同じままである。一方、ロック部材２７が最大離間位置から中間位置まで回転すると、端子ユニット３８の一対の第二カムフォロア５１は第二カム溝３２の中間部に係合（ピン突出用カム面３３とピン突出用カム面７１の時計方向側端部と係合）する（図７（ｂ）の符号５１Ｂ参照）。そのため、支持突起５０が対応するスリット８２内を下方へ移動しかつ端子支持部材４２及び防滴部材５３が非円形貫通孔８９内を下方へ移動しながら端子ユニット３８全体がベース７８に対して下方へ移動するので、端子５５及びロックピン５９が最大離間位置に位置するときよりもベース７８に対して下方へ相対移動する。そのため、端子５５の突出部５７及びロックピン５９の突出部（下端部）が、防滴部材５３の下端面から下方に突出しかつ取付部８０の下端面から下方へ突出する（図１０参照。但しロックピン５９は図示略）。さらに防滴部材５３の下部が取付部８０の下端面より下方へ突出する（図示略）。 When the lock member 27 located at the maximum separation position is rotated counterclockwise in plan view while using the knob 29, the lock member 27 is rotated to the intermediate position shown in FIG. When the lock member 27 rotates from the maximum separation position to the intermediate position, the pair of first cam followers 31 of the lock member 27 engage with the intermediate portion of the first cam groove 85 (the pin protrusion allowable cam surface 25a and the pin protrusion allowable cam surface). 86 (see reference numeral 31B in FIG. 8). As described above, since the pin protrusion allowable cam surface 25a and the pin protrusion allowable cam surface 86 are cam surfaces configured by a horizontal plane, the vertical position of the lock member 27 with respect to the base 78 remains the same as in the maximum separated position. On the other hand, when the lock member 27 rotates from the maximum separated position to the intermediate position, the pair of second cam followers 51 of the terminal unit 38 engages with the intermediate portion of the second cam groove 32 (the pin protruding cam surface 33 and the pin protruding cam). Engaging with the clockwise end of the surface 71 (see reference numeral 51B in FIG. 7B). Therefore, the entire terminal unit 38 moves downward with respect to the base 78 while the support protrusion 50 moves downward in the corresponding slit 82 and the terminal support member 42 and the drip-proof member 53 move downward in the non-circular through hole 89. Therefore, the terminal 55 and the lock pin 59 are relatively moved downward with respect to the base 78 rather than being located at the maximum separation position. Therefore, the protruding portion 57 of the terminal 55 and the protruding portion (lower end portion) of the lock pin 59 protrude downward from the lower end surface of the drip-proof member 53 and protrude downward from the lower end surface of the mounting portion 80 (see FIG. 10, however. The lock pin 59 is not shown). Further, the lower part of the drip-proof member 53 protrudes downward from the lower end surface of the attachment part 80 (not shown).

摘み部２９を利用しながらロック部材２７を平面視で反時計方向に回転させると、ロック部材２７が図１１に示す挟持位置まで回転する。ロック部材２７が中間位置から挟持位置まで回転するとき、ロック部材２７の一対の第一カムフォロア３１は第一カム溝８５の反時計方向側端部に係合（ピン突出量調整用カム面２５ｂとピン突出量調整用カム面８７の反時計方向側端部と係合）する（図８の符号３１Ｃ参照）。上記したようにピン突出量調整用カム面２５ｂとピン突出量調整用カム面８７は反時計方向側に進むに従って下方へ延びる傾斜カム面であるため、ロック部材２７のベース７８に対する上下方向位置は最大離間位置及び中間位置のときよりも下方となる。その結果、ロック部材２７と取付部８０との上下間隔がアクセサリーシュー１２の被挟持部１５の厚み（上下寸法）と同じか又は僅かに小さくなる。またロック部材２７が中間位置から挟持位置まで回転すると、端子ユニット３８の一対の第二カムフォロア５１は第二カム溝３２の時計方向側端部に係合（ロック用カム面３４とロック用カム面７２の時計方向側端部と係合）する（図７（ｂ）の符号５１Ｃ参照）。そのため端子ユニット３８（端子５５、ロックピン５９）は中間位置に位置するときよりもロック部材２７に対して上方へ相対移動する。但し、ロック部材２７が中間位置から挟持位置まで回転するときの端子ユニット３８（端子５５、ロックピン５９）のロック部材２７に対する上方への相対移動量よりも、ロック部材２７が中間位置から挟持位置まで回転するときのロック部材２７のベース７８に対する下方への相対移動量が大きいので、端子５５及びロックピン５９は中間位置に位置するときよりもベース７８に対して下方へ移動する。その結果、（端子５５及びロックピン５９の下方への突出が他の部材によって妨げられないとき）端子５５の突出部５７及びロックピン５９の突出部（下端部）の防滴部材５３の下端面及び取付部８０の下端面からの下方への突出量が中間位置に位置するときよりも大きくなる。また支持突起５０が対応するスリット８２内を下方へ移動しかつ端子支持部材４２及び防滴部材５３が非円形貫通孔８９内を下方へ移動しながら端子ユニット３８全体がベース７８に対して中間位置のときよりも下方へ移動するので、（防滴部材５３の下方への突出が他の部材によって妨げられないとき）防滴部材５３の下部の取付部８０の下端面からの下方への突出量が中間位置に位置するときよりも大きくなる。 When the lock member 27 is rotated counterclockwise in plan view while using the knob 29, the lock member 27 is rotated to the clamping position shown in FIG. When the lock member 27 rotates from the intermediate position to the clamping position, the pair of first cam followers 31 of the lock member 27 are engaged with the counterclockwise ends of the first cam groove 85 (the pin protrusion amount adjusting cam surface 25b and Engaging with the counterclockwise end of the pin protrusion amount adjusting cam surface 87 (see reference numeral 31C in FIG. 8). As described above, the pin protrusion amount adjusting cam surface 25b and the pin protrusion amount adjusting cam surface 87 are inclined cam surfaces that extend downward as they proceed in the counterclockwise direction, so that the vertical position of the lock member 27 with respect to the base 78 is It is lower than at the maximum separation position and intermediate position. As a result, the vertical distance between the lock member 27 and the mounting portion 80 is the same as or slightly smaller than the thickness (vertical dimension) of the sandwiched portion 15 of the accessory shoe 12. When the lock member 27 rotates from the intermediate position to the clamping position, the pair of second cam followers 51 of the terminal unit 38 are engaged with the clockwise end portions of the second cam groove 32 (the lock cam surface 34 and the lock cam surface 34). 72 (see the reference numeral 51C in FIG. 7B). Therefore, the terminal unit 38 (the terminal 55 and the lock pin 59) moves relatively upward with respect to the lock member 27 rather than being located at the intermediate position. However, when the lock member 27 rotates from the intermediate position to the clamping position, the lock member 27 is moved from the intermediate position to the clamping position more than the relative movement amount of the terminal unit 38 (terminal 55, lock pin 59) with respect to the lock member 27. Therefore, the terminal 55 and the lock pin 59 are moved downward relative to the base 78 rather than being located at the intermediate position. As a result (when the downward protrusion of the terminal 55 and the lock pin 59 is not hindered by other members), the lower end surface of the drip-proof member 53 of the protrusion 57 of the terminal 55 and the protrusion (lower end) of the lock pin 59 And the protrusion amount to the downward direction from the lower end surface of the attaching part 80 becomes larger than when it is located in an intermediate position. Further, the entire terminal unit 38 is in an intermediate position with respect to the base 78 while the support protrusion 50 moves downward in the corresponding slit 82 and the terminal support member 42 and the drip-proof member 53 move downward in the non-circular through hole 89. The amount of downward protrusion from the lower end surface of the mounting portion 80 at the lower part of the drip-proof member 53 (when the downward protrusion of the drip-proof member 53 is not hindered by other members) Is larger than when it is located at the intermediate position.

続いてストロボ２０のカメラ１０に対する着脱要領について説明する。
図１、図２に示すようにカメラ１０から離間させたストロボ２０のロック部材２７を最大離間位置に位置させて、端子５５及びロックピン５９の下端部を防滴部材５３及び取付部８０の下端面より上方に位置させておく。そしてアクセサリーシュー１２の後端開口から左右の被挟持部１５と底板部１３の間の空間に取付部８０を挿入する（図９（ａ）参照）。このとき取付部８０の前端部を底板部１３の前後方向の中間部と同じ位置に位置させ（底板部１３の前端部より後方に位置させ）、端子５５及びロックピン５９を露出用切欠１３ａの直上に位置させる。取付部８０の厚み（上下寸法）は底板部１３と被挟持部１５の間の隙間（上下寸法）より短くかつ端子５５及びロックピン５９の下端部が取付部８０の下端面より上方に位置している（取付部８０の下端面から下方に突出していない）ので、このとき取付部８０を左右の被挟持部１５と底板部１３の間の空間に対して円滑に挿入できる。 Next, how to attach / detach the strobe 20 to / from the camera 10 will be described.
As shown in FIGS. 1 and 2, the lock member 27 of the strobe 20 separated from the camera 10 is positioned at the maximum separation position, and the lower ends of the terminal 55 and the lock pin 59 are below the drip-proof member 53 and the mounting portion 80. It is located above the end face. Then, the attachment portion 80 is inserted into the space between the left and right sandwiched portions 15 and the bottom plate portion 13 from the rear end opening of the accessory shoe 12 (see FIG. 9A). At this time, the front end portion of the mounting portion 80 is located at the same position as the middle portion of the bottom plate portion 13 in the front-rear direction (positioned rearward from the front end portion of the bottom plate portion 13), and the terminal 55 and the lock pin 59 are Position it directly above. The thickness (vertical dimension) of the mounting part 80 is shorter than the gap (vertical dimension) between the bottom plate part 13 and the sandwiched part 15, and the lower ends of the terminal 55 and the lock pin 59 are positioned above the lower end surface of the mounting part 80. Since it does not protrude downward from the lower end surface of the attachment portion 80, the attachment portion 80 can be smoothly inserted into the space between the left and right sandwiched portions 15 and the bottom plate portion 13 at this time.

続いて、ロック部材２７を中間位置まで回転操作して端子５５及びロックピン５９の下端部を防滴部材５３及び取付部８０の下端面から下方へ突出させて、各端子５５の下端部を露出用切欠１３ａを介して露出した外装ケース１１ａの上面に接触させる（図１０参照）。すると取付部８０の上面が左右の被挟持部１５の下面に接触した状態で、端子５５（の突出部５７）及びロックピン５９（の突出部）が外装ケース１１ａから受ける反力によって対応する圧縮コイルバネ６２を圧縮方向に弾性変形させながら端子支持部材４２（取付部８０）に対して僅かに上方へ相対移動し、かつ、防滴部材５３が底板部１３と接触することにより上下方向に圧縮されるので、取付部８０（シュー２１）がアクセサリーシュー１２に対してガタつかなくなる。この状態で取付部８０（シュー２１）をアクセサリーシュー１２（カメラボディ１１）に対して前方にスライドさせると、各端子５５の突出部５７が対応する各カメラ側端子１１ｂの表面上を摺動しながら前方へ相対移動するので、突出部５７やカメラ側端子１１ｂの表面に付着していた酸化膜や汚れが除去される。そのため各端子５５（突出部５７）とカメラ側端子１１ｂが確実に導通可能となる。またロックピン５９がロック用凹部１１ｃと対応する位置までスライドすると、対応する圧縮コイルバネ６２の付勢力によってロックピン５９が端子支持部材４２（及びベース７８）に対して下方へ相対移動し、その下端部（突出部）がロック用凹部１１ｃに対して係合する。このとき操作者はロックピン５９とロック用凹部１１ｃの係合に伴うクリック感を感じることができるので、取付部８０（シュー２１）のアクセサリーシュー１２に対する前後位置が正規の装着位置に到達したことを認識できる（但し、クリック感を感じることができないようにロックピン５９とロック用凹部１１ｃを設計し、操作者の目視により取付部８０が正規の装着位置に位置することを認識してもよい）。 Subsequently, the lock member 27 is rotated to an intermediate position so that the lower end portions of the terminal 55 and the lock pin 59 protrude downward from the lower end surfaces of the drip-proof member 53 and the mounting portion 80, and the lower end portions of the terminals 55 are exposed. It is made to contact the upper surface of the exterior case 11a exposed through the notch 13a (see FIG. 10). Then, in a state in which the upper surface of the mounting portion 80 is in contact with the lower surfaces of the left and right sandwiched portions 15, the terminal 55 (the projecting portion 57) and the lock pin 59 (the projecting portion) are subjected to corresponding compression by the reaction force received from the outer case 11a. While the coil spring 62 is elastically deformed in the compression direction, the coil spring 62 is moved slightly upward relative to the terminal support member 42 (attachment portion 80), and the drip-proof member 53 is compressed in the vertical direction by contacting the bottom plate portion 13. Therefore, the attachment portion 80 (shoe 21) does not rattle with respect to the accessory shoe 12. In this state, when the mounting portion 80 (shoe 21) is slid forward with respect to the accessory shoe 12 (camera body 11), the protruding portion 57 of each terminal 55 slides on the surface of the corresponding camera side terminal 11b. However, since it moves relatively forward, the oxide film and dirt adhering to the surface of the protrusion 57 and the camera side terminal 11b are removed. Therefore, each terminal 55 (projection part 57) and the camera side terminal 11b can be reliably connected. When the lock pin 59 slides to a position corresponding to the lock recess 11c, the lock pin 59 is moved downward relative to the terminal support member 42 (and the base 78) by the biasing force of the corresponding compression coil spring 62, and its lower end. The portion (projection) engages with the locking recess 11c. At this time, since the operator can feel a click feeling associated with the engagement between the lock pin 59 and the locking recess 11c, the front-rear position of the mounting portion 80 (shoe 21) with respect to the accessory shoe 12 has reached the proper mounting position. (However, it is also possible to design the lock pin 59 and the locking recess 11c so as not to feel a click feeling, and to recognize that the mounting portion 80 is located at the proper mounting position by visual observation of the operator. ).

この状態でロック部材２７を挟持位置まで回転させると、ロック部材２７の下面が左右の被挟持部１５の上面に対して上方から接触する（図３、図１１（ａ）参照）。即ち、左右の被挟持部１５が取付部８０とロック部材２７によって上下から挟持される。そのため取付部８０（シュー２１）がアクセサリーシュー１２に対して固定される。さらに（端子５５及びロックピン５９の下方への突出が他の部材によって妨げられない場合に、端子５５の突出部５７及びロックピン５９の突出部の取付部８０の下端面からの下方への突出量が中間位置に位置するときよりも大きくなるので）各端子５５とカメラ側端子１１ｂの接触圧力がより高くなり、かつ、ロックピン５９とロック用凹部１１ｃの係合状態がより安定する。さらに（防滴部材５３の下方への突出が他の部材によって妨げられないとき、防滴部材５３の下部の取付部８０の下端面からの下方への突出量が中間位置に位置するときよりも大きくなるので）防滴部材５３が端子支持部材４２と底板部１３によって強い力で圧縮されるので、防滴部材５３と底板部１３の間から水滴等が端子５５の突出部５７とカメラ側端子１１ｂの間に流れて、これらの部材に付着するおそれが殆どなくなる。
このようにしてシュー２１の各端子５５をカメラボディ１１側の各カメラ側端子１１ｂに接触させると、カメラボディ１１内に設けたバッテリ（図示略）の電力が上記電源回路、カメラ側端子１１ｂ、及び端子５５を介してストロボ２０の上記発光部に伝わるので、カメラボディ１１に設けたストロボ操作手段を操作すればストロボ２０の発光部が発光する。
またシュー２１に設けたグランド接点部材９２がアクセサリーシュー１２の内面に接触する。その結果、ストロボ本体内に設けたグランド端子、グランド接点部材９２、アクセサリーシュー１２、及びカメラボディ１１内に設けたアクセサリーシュー１２と接続する金属製シャーシアースが互いに導通する。 When the lock member 27 is rotated to the clamping position in this state, the lower surface of the lock member 27 comes into contact with the upper surfaces of the left and right sandwiched portions 15 from above (see FIGS. 3 and 11A). That is, the left and right sandwiched portions 15 are sandwiched from above and below by the attachment portion 80 and the lock member 27. Therefore, the attachment portion 80 (shoe 21) is fixed to the accessory shoe 12. Further, when the protrusion of the terminal 55 and the lock pin 59 is not obstructed by other members, the protrusion of the protrusion 55 of the terminal 55 and the protrusion of the lock pin 59 protrude downward from the lower end surface of the mounting portion 80. The contact pressure between each terminal 55 and the camera-side terminal 11b becomes higher and the engagement state between the lock pin 59 and the locking recess 11c becomes more stable (because the amount is larger than when it is located at the intermediate position). Further (when the downward protrusion of the drip-proof member 53 is not hindered by other members, the amount of downward protrusion from the lower end surface of the lower mounting portion 80 of the drip-proof member 53 is more than when it is located at the intermediate position. Since the drip-proof member 53 is compressed with a strong force by the terminal support member 42 and the bottom plate portion 13, water droplets or the like from between the drip-proof member 53 and the bottom plate portion 13 cause the protrusions 57 of the terminal 55 and the camera side terminal There is almost no risk of flowing between these members and adhering to these members.
Thus, when each terminal 55 of the shoe 21 is brought into contact with each camera side terminal 11b on the camera body 11, the power of a battery (not shown) provided in the camera body 11 is supplied to the power supply circuit, the camera side terminal 11b, Since the light is transmitted to the light emitting part of the strobe 20 via the terminal 55 and the strobe operating means provided on the camera body 11 is operated, the light emitting part of the strobe 20 emits light.
A ground contact member 92 provided on the shoe 21 contacts the inner surface of the accessory shoe 12. As a result, the ground terminal provided in the strobe body, the ground contact member 92, the accessory shoe 12, and the metal chassis ground connected to the accessory shoe 12 provided in the camera body 11 are electrically connected to each other.

ストロボ２０をカメラ１０（アクセサリーシュー１２）から取り外す場合は、ロック部材２７を最大離間位置まで回転させる。すると端子５５及びロックピン５９の下端部が取付部８０及び防滴部材５３の下端面より上方に移動する（取付部８０及び防滴部材５３の下端面から下方に突出しなくなる）ので、取付部８０を左右の被挟持部１５と底板部１３の間の空間からアクセサリーシュー１２の後方へ円滑に取り外すことが可能になる。 When removing the strobe 20 from the camera 10 (accessory shoe 12), the lock member 27 is rotated to the maximum separation position. Then, the lower end portions of the terminal 55 and the lock pin 59 move upward from the lower end surfaces of the attachment portion 80 and the drip-proof member 53 (they do not protrude downward from the lower end surfaces of the attachment portion 80 and the drip-proof member 53). Can be smoothly removed from the space between the left and right sandwiched portions 15 and the bottom plate portion 13 to the rear of the accessory shoe 12.
