FIGS. 1(a) and 1(b) are side views of a camera body C and a flash light emitting device (hereinafter referred to as a strobe device) S. FIG. The strobe device S has a strobe foot SI, which is an accessory-side mounting part provided at the bottom, and an accessory foot SI, which is an accessory-side mounting part provided at the bottom of the camera body C. It is attached to the camera body C by sliding it from the back to the front.The strobe device S is equipped with an auxiliary light projection device AL that projects auxiliary light for automatic focus detection. .

Figure 2 shows the accessory shoe C fitted into each other when the strobe device S is attached to the camera body C.
8 and the strobe foot SH in a direction perpendicular to the optical axis of the camera, and FIG. 3 is a sectional view of the accessory shoe C8 and the strobe foot SR fitted together in the direction of the optical axis of the camera. Further, FIG. 4 is a configuration diagram of the accessory shoe C8 and the strobe foot SH.

Hereinafter, the structure and fitting operation of the accessory saw C8 and the strobe foot S1 will be described in detail with reference to FIGS. 2, 3, and 4.

In Fig. 2, the accessory saw -C9 is a shoe 1 integrally formed of plastic, =8- an electric terminal 2 for transmitting and receiving signals with the strobe device S, and a strobe for supplying power for the strobe. Power terminal 6, external member of camera such as Nikaher 4. and a bottom plate 3 disposed between the shoe 1 and the exterior member 4. Further, the strobe foot S H includes a foot body 10, a movable contact 12 that can be slid up and down for transmitting and receiving signals with the camera body C, a movable power supply terminal I4 that can also be slid up and down, and the above-mentioned It is roughly composed of a holding plate 11 that serves as a guide for the movable contact I2.

First, the accessory shoe C8 will be explained in detail. The above-mentioned Niko I has a substantially T-shaped cross-sectional shape with an eave part in two parts, and for example, four Neno 9 (only two are shown) are inserted from the inside of the exterior member 4 through the reinforcing plate 5 and the bottom plate 3. The four corners are fixed to the exterior member 4 by. The strobe device S of this embodiment is a compact strobe device S of a type in which there is no power source on the strobe device S side (the power source is shared with the camera body C).This strobe device S has an approximately T-shaped cross section. Lower surface 1 of the eaves part of the shoe I above
Two strobe power terminals 6, a pot line P (+) and a power ground PC, are provided at the position of the exterior member 4 facing b and lb, and when the strobe device S is attached to the camera body C, the strobe power terminals 6 and the movable power supply terminal 14 are automatically connected. Therefore, the strobe power supply means can be integrated into the camera-side mounting part and the accessory-side mounting part, and there is no need to separately provide a strobe power supply means. The strobe power supply terminal 6 is directly connected to the power supply of the camera body C since a large current is required when power is supplied to the strobe device S. That is, this strobe power supply terminal 6 is fixed to the exterior member 4 by caulking, and a lug plate 7 for soldering is connected to its lower end. The lug plate 7 is directly connected to a battery power terminal in the camera body C (not shown) via a lead wire 8'.

Furthermore, the two strobe power supply terminals 6 (P and P
G) The lower part of the eaves (X, Y (as shown in the figure). If the system 1, the bottom plate 3, and the exterior member 4 are made of, for example, a plus deck insulator, the electric terminal 2 and the strobe power supply terminal 6
insulation can be easily ensured. Furthermore, as shown in FIG. 2, a groove 4a is arranged around the strobe power supply terminal 6 to prevent current leakage caused by a film of water, sweat, etc. due to capillary action.

In this embodiment, the strobe power supply terminal 6 is provided in the exterior member 4 with a concave portion sandwiched between the convex portions 4b. Even if the power supply terminal 6 for the strobe is actively opened without opening the power supply terminal 6, since the power supply terminal is located under the eaves, there is no fear of inadvertently touching it.

Next, the arrangement of the electrical terminals 2 will be explained according to FIGS. 5(a) and 5(b) (plan views of the camera-side mounting portion).

FIG. 5(a) shows a two-row type, and FIG. 5(b) shows a one-row type. In the two-row type shown in Fig. 5(a), each electrical terminal 2 is arranged in two rows to prevent short-circuiting of the electrical terminals 2 due to water, sweat, dust, etc. and to improve reliability. is,
In addition, the electrical terminals 2 in each row are arranged in different phases so that the intervals between the terminals are as wide as possible. A separating strip 1c is provided at the center of the two terminal rows to isolate the terminal rows.

The electrical terminal 2 shown in FIGS. 5(a) and 5(b) is provided in a groove Ia provided in the center of the upper surface of the shoe 1 for horizontal positioning. As shown in FIG. 4, the rear end of this groove la communicates with the outside. In this way, by providing the electrical terminal 2 within the width ft1a that does not allow a human finger to enter, the electrical terminal 2 is prevented from being directly touched by a child.

In a camera of the type described above in which power is supplied to the strobe device S from the camera body C side, signal transmission between the camera body C and the strobe device S is performed by, for example, five electric terminals 2.

The lock groove 1d provided in the groove la is for locking the strobe device S so that it does not come off the camera body C when the strobe device S is attached to the camera body C, as will be described in detail later. It is. This lock groove 1d is
When the strobe device S is attached to the camera body C, the electric terminal 2 in the groove la is arranged so that the movable contact 12 on the strobe device S side does not fall into the lock groove ld and be damaged.
It is formed further forward than the

Next, FIG. 2 shows the strobe foot SH.

Figures 3 and 5 (C) (bottom view of strobe foot)
This will be explained in detail based on the following. The foot main body IO has a foot portion lob, 10b that fits between the lower surface 1b, lb of both eaves portions of the shoe 1 and the bottom plate 3, which are integrally formed of plastic. And this foot part 10b
Lower surface 10c, bottom plate 3, and upper surface 1 of foot portion 10b
Vertical positioning is performed by Oe and the lower surface 1b of the eave portion of the shoe L as will be described in detail later. At the lower center of the foot body IO, there is provided a protrusion 10a for horizontal positioning that fits into the groove 1a provided on the upper surface of the shoe I. Horizontal positioning is performed in a manner that will be described in more detail later.

A movable contact I2 is vertically arranged at a position of the convex portion 10a corresponding to the position of the electric terminal 2. The movable contact 12 is constantly urged downward by a spring 13 as shown in FIG.
It protrudes from the lower surface of a. By doing this, when the four-point device S is installed, the lower surface of the movable contact 12 slides on the electrical terminal 2 and self-cleans, ensuring that the electrical terminal 2 and the movable contact 12 are in contact with each other. be able to transmit signals. The holding plate 11 is a plate that fixes the upper end of the spring 13 and also holds the movable contact 12, and is fixed to the foot body 10 with a screw 20.

Furthermore, in the case of a strobe device S that is supplied with an electric wire from the camera body C side, a movable power source for supplying electricity to the battery of the strobe device S is provided at a position of the foot portion 10b corresponding to the strobe power terminal 6. A terminal 14 is provided (pull). This movable power supply terminal 14 is always urged downward by a spring I5 whose one end is fixed by a holding plate 11, as in the case of the movable contact I2. As shown in the figure, the foot portion 10b protrudes from the lower surface of the foot portion 10b.By doing so, when the strobe device S is attached, the strobe power terminal 6 is connected to the movable power terminal 14.
By sliding the lower surface of the movable power terminal 14, self-cleaning is performed, and the strobe power terminal 6 and the movable power terminal 14 can reliably come into contact with each other. The stop plate 16 is the movable power supply terminal 1
This is a member for determining the lowest position of No. 4.

Next, locking of the strobe device S when the strobe device S is attached to the camera body C will be explained in detail. As shown in FIG. 3, the lock lever 21 locks the strobe device S when the strobe device S is attached to the camera body C. This lock lever 21 is always urged downward by a lock spring I7. When the strobe device S has been installed, it is inserted into the lock groove 1d provided in the lock portion 1ah<groove 1a provided at the tip of the lock lever 21, and the strobe device S is locked. state. At that time, the locking member 21a is
As the separation strip 1c is slid over the electrical terminal 2,
There's no way you'll be disappointed. On the other hand, if you do not want to remove the strobe device S, do not press the lock release button 19. Then,
One end +8b of the lock release lever 18 is pushed and the lock release lever 18 is rotated about the shaft 11a. Then, the lock lever 21 attached to the tip of the lock release lever 18 by a hook 18a is moved upward against the urging force of the spring 17, and the lock portion side 21a is separated from the lock groove 1d. Therefore, the strobe device S can be slid and separated from the camera body C. In Fig. 3, the lock release button I9 is located at the rear of the strobe foot 5r-1, but when removing the strobe device S from the camera body C, the thumb, middle finger, and ring finger naturally come into contact with it. For example, press the lock release button I9 in the position shown by S L in Figure 1.
Take.

Next, horizontal and vertical positioning when attaching the strobe device S to the camera body C will be described in detail.

Horizontal positioning is performed using the groove 1a and the convex portion 10a as described above.
It is done by both sides. As shown in FIG. 5, the iM I a (and the convex portion 10a) is designed so that the widths a and α at the front end (on the lens side) are narrower than the widths i and β at the rear end, respectively (that is, a < b, α<β), and the space between them is tapered.

Therefore, the length for positioning may be a small distance (for example, 1 to 2 mm) both forward and backward. That is, since the horizontal positioning is carried out along the entire length of the groove 1a (and not by the length of the groove 1a), it is carried out only by a small distance between the front and rear parts of the groove 1a at the final stage of installation. While installing the strobe device S, the side surface of the groove 1a and the convex portion 1
It is easy to put on and take off without getting caught due to friction with the side surface of 0a, and the feel when wearing it is also excellent. In addition, as mentioned above, since it is possible to securely fit within a short distance and improve the fitting accuracy, the distance required for horizontal positioning is small, and the range that requires high processing accuracy is narrow and manufacturing is possible. It also has the advantage of being easy to do. Furthermore, the convex portion 10
The width a of the front end of a is the rear end of the groove 1a (the insertion opening of the convex part 10a)
Since the width of the strobe device S is narrower than that of the camera body C, it is easy to aim and insert the strobe device S when attaching it to the camera body C.

Further, the vertical positioning is performed by the lower surfaces 1b and lb of the eaves of the shoe 1 and the upper surface 10 of the foot portion 10b, as described above.
e and 10e. Bottom surface 1 of the above eaves part
b is Fig. 6 (A-A cross-sectional view in Fig. 2 and Fig. 4)
Further, as shown in FIG.

, a rear portion lb2, and a sloped portion lb3 located between the two. The dimensions of the foot part +ob inserted between the lower surface 1b, lb of the eave part and the bottom plate 3 are the dimensions of the front part (
The thickness C of the rear portion (corresponding to Ib2 of the lower surface of the eaves) is thinner than the thickness d of the rear portion (corresponding to Ib2 of the lower surface of the eaves) (that is, c<d). therefore,
As in the case of horizontal positioning described above, vertical positioning is performed at the final stage of installation by only a small distance between the front and rear parts of the foot part 10b, which facilitates insertion and
It does not get caught when worn, is easy to put on and take off, and has an excellent feel when worn.

Here, as shown in FIG. 6, the length of the convex portion 10a for horizontal positioning is 1. is longer than the length 11 of the foot portion 10b for vertical positioning (that is, +2>+). When the strobe is attached, the convex portion 1 is first used for horizontal positioning.
The part protruding from the foot part 10b at 0a (
Horizontal guidance is provided by length -12-10;
Subsequently, the foot portions 10b, 10b are connected to the eaves portions 1b, I.
The strobe device S is inserted between the strobe device S and the bottom plate 3, thereby making it easy to install the strobe device S. At that time,
Initially, the bottom surface 10x of the foot body IO is the top surface lx of the shoe 1.
(See Figure 6). However, the foot portion 10
Since the lower front end 10y of the foot body IO is chamfered, the foot portion 10b can eventually ride on the bent portion 3a of the bottom plate 3, and the lower surface 10x of the foot body IO and the shoe 1
A gap is created between the upper surface IX and the upper surface IX. Therefore, after that, a gap ε can be maintained between the lower surface 10x of the foot body IO and the upper surface 1x of the shoe 1, and the upper surface 1x of the shoe 1 can be maintained.
The foot portion 10b is fitted smoothly without causing any damage.

Next, the amount of backlash when the strobe device S is attached to the camera body C will be explained in detail.

In FIG. 7, if the strobe foot width is denoted by M, the horizontal positioning length is denoted by M, and the gap amount is denoted by δ, then the play amount (horizontal rotation amount) θ can be determined as follows.

cos (θ0−θ) −cosθ. +δ/Ivlsi
nθ.

=1+(67M)″・cos(θ0−α)・(A) However, tanα−δ/M, α×θ Here, if δm1n−0.2mm and M=18mm, δ/M=0.011 .1+(67M)″ 1, and janθ5δ/M. Therefore, the play amount θ is δ
The smaller the value is and the larger M is, the smaller it becomes, and it is approximately determined by the size of 67M.

Next, let's consider the effect of strobe foot width.

If we differentiate both sides of equation (A) with 61M constant, we get dθ/dθ. <0, and it can be seen that the backlash amount θ decreases with an increase in θ0, that is, a decrease in L.

From the above, horizontal positioning can be achieved by increasing the horizontal positioning length M and narrowing the strobe foot width L (that is, the horizontal positioning width).

Therefore, in this embodiment, the camera side vertical positioning part (i.e., the lower surface 1b of the eave part of the shoe I,
A groove 1a, which is a horizontal positioning part on the camera side, is provided in the center of the upper surface of the shoe l on the inside of Ib), and its width (a or b) is made as narrow as possible within the range that ensures the reliability of the electrical terminal 2. In this example, it is approximately 4 mm), and its length is made as long as possible (approximately 10 mm in this example) to reduce the amount of play in the horizontal direction and to obtain high positioning accuracy. . Further, by narrowing the width of the groove 1a in this way, the electric terminal 2 installed in the groove Ia as described above does not come into contact with fingers or the like.

Further, as mentioned above, the width a of the front end of the groove 1a is changed to the width b of the rear end.
'J: The width is slightly narrower, and the thickness of the front part of the foot part 10b is C.
The rear part is thicker (+), and the rear part is also made slightly thinner, so that the horizontal and vertical positioning of the strobe device S can be adjusted by i%.
This is done at the final stage of installation by only a small distance between t I a and the oil part of the foot part 10b and the rear part. Therefore, the strobe foot S I-1 can be easily inserted into the accessory nokko C8, and the strobe device S can be easily installed without getting caught.

Furthermore, as described in "--, the length 12 of the convex portion 10a for performing horizontal positioning is made longer than the length 11 of the foot portion 10b for performing vertical positioning. Therefore, when the strobe device S is attached to the camera body 0, horizontal guidance is first performed by the portion of the convex portion 10a that protrudes beyond the foot portion 10b, and then by the foot portion 10b.

10b is inserted between the eaves portions 1b, Ib and the bottom plate 3, so that the strobe device S can be easily attached. In this way, in this embodiment, L>1. However, it may be set so that +2<II.

Therefore, according to this embodiment, the play of the strobe device S is extremely small even if it is not fixed with a nut or the like as in the conventional case, and the cross-sectional area of the electric terminal 2 is reduced to allow the accessory no. Strobe foot S
H can be turned into Combat I. Also, Sony I
If the foot body 10 is made of plastic, the elastic deformation of the plastic deck can be used to better fit the lower surface Ib3 of the shoe 1 into the foot part 10b, and vertical play can be minimized. I can do it,
It is also possible to achieve lower cost than forming it from metal.

In this embodiment, the electric terminal 2 is placed in a groove Ia provided in the center of the second surface of the shoe 1. Therefore, the electrical terminal 2 will not be touched carelessly by hands or the like. In addition, since the movable contact 12 is always urged downward by the spring 13, self-cleaning when the strobe device S is attached removes the electrical terminal 2 and the movable contact 1.
It is possible to maintain electrically stable contact even if the tip surface of 2 becomes rusted or corroded.

In this embodiment, a strobe power supply terminal 6 and two movable power supply terminals 14 connected to the strobe power supply terminal 6 are separated on both sides of the base of Tsuyu-I at the lower part of the eaves of saw-1. It is arranged as follows. Therefore, the two movable power supply terminals 14 are connected to each other by hand.

No short circuit caused by water, sweat, etc. In addition, since the movable power terminal 14 is always heated downward by the ij spring 15, even if the tip surfaces of the strobe power terminal 6 and the movable power terminal 14 become corroded or rusted due to self-cleaning when the strobe device is attached, the electricity will not be removed. can maintain stable contact. In addition, strobe device S
When attached to the camera body C, it is automatically connected to the strobe power supply terminal 6 (J movable power supply terminal 14), so there is no need to separately provide a power supply means for the strobe.

In the above embodiment, a shoe 1 with a substantially T-shaped cross section is provided on the camera body C side, but a strobe foot with a substantially T-shaped cross section is provided on the strobe device S side, and the shoe 1 is fitted onto the strobe foot on the camera body C side. However, in order to make the accessory Sony on the camera side mounting part relatively simple in shape and smaller in volume, the arrangement as in this example is preferable. .

In addition, in the "-set number embodiment, horizontal positioning is performed by both sides of the groove 1a and the convex part 10a,
Side surfaces 1d and ld of Sony 1 and side surface 10 of foot portion 10b
d, lOd. However, in that case, the horizontal positioning width will be wider than in each of the above embodiments, so the amount of backlash will be slightly larger.

Further, in the above embodiment, the shape of the recess 1a and the convex portion 10a for horizontal positioning of the strobe device S is
Although it has a shape as schematically shown in FIG. 8(a), it may have a shape as schematically shown in FIGS. 8(b), (c), and (d). Fig. 8(b) shows a tapered part in the groove 21b (to facilitate fitting to the J strobe foot SI (accessory series: s--CS).
In Figure (C), the convex portion 40a is provided with a tapered portion to facilitate fitting of the strobe foot SH to the accessory shoe C8.

<Effects of the Invention> As is clear from the above, the camera and accessory mounting device of the present invention has a camera side vertical positioning section and an accessory side vertical positioning section on the camera side mounting section and the accessory side dam mounting section. Since a guide part is provided that protrudes forward in the mounting direction from the front end of the part, when sliding and inserting the accessory side dam attachment part into the camera side attachment part,
First, the guides provided on the camera-side attachment part and the accessory-side dam attachment part can provide horizontal guidance, and the accessory-side attachment part can be smoothly inserted into the camera-side attachment part.
