Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a camera and an accessory mounting device that can removably attach an accessory to a camera.

<Prior art> Conventionally, as a camera and accessory mounting device for mounting accessories such as a strobe device to a camera, there are devices as shown in the plan view and cross-sectional view of FIGS. 9(a) and (11). . This mounting device connects the strobe foot 72, which is the accessory mounting part, to the camera side weir (=
The strobe device is attached to the camera by inserting and fitting it into the accessory bolt 71, which is the J section. At this time, positioning in the left and right directions in the figure (hereinafter referred to as horizontal positioning) is performed using the parallel side surfaces 61 of the strobe foot 72.
．． 61 and the parallel inner surface 62°62 of the accessory shoe 71. On the other hand, positioning in the downward direction (hereinafter referred to as "vertical positioning") in "1" in the figure is achieved by rotating the nut 73 to lock the inner surface 63.63 of the accessory shoe 71 and the upper surface 64.64 of the strobe foot 72. I try to do it.

<Problem to be solved by the invention> In recent years, reflex cameras equipped with AP (autofocus) have become mainstream. An increasing number of RoPo devices have a function of projecting auxiliary projection light.

However, when attaching the strobe device to the camera body, if the optical axis of the projected light from the strobe device shifts due to looseness in the mounting device, the effective range of the auxiliary light ΔF will be extremely limited. It ends up.

Therefore, it is necessary to improve the accuracy of the strobe device on the camera.

However, in the above-described conventional camera and accessory mounting device, horizontal positioning is performed by the parallel sides 61.61 of the strut foot 72 and parallel inner sides 62.62 of the accessory shoe 7 ridge, while the vertical Directional positioning is done using the inner surface 63.63 of the accessory ink 71.
The horizontal positioning section on the accessory side and the horizontal direction positioning section on the camera side are the side surfaces 61.61 and -1 of the strobe foot 72. - Fits over the entire length of the overlapping portion with the inner surface 62, 62 of the accessory string yaw 71. Therefore, the length of the mating surface (hereinafter referred to as the mating length) is long when attached, and the side surface 61.61 of the strobe foot 72 and the accessory shoe 71 are long.
If the gap between the strobe foot 72 and the inner surface 62 of the strobe foot 72 is narrowed to prevent it from rattling in the horizontal direction, there is a problem that when inserting the strobe foot 72 into the accessory sheet 71, it gets caught and cannot be easily attached or detached. .

Manoko, the width of the front end of the strobe foot 72 in the mounting direction (distance between the side surfaces 61.61) and the width of the insertion opening of the strobe foot 72 (distance between the inside surfaces 62.62 of the accessory sheet 71) are approximately the same. Since it is the same, strobe foot 72
There is also the problem that it is difficult to aim the insertion position when inserting the accessory into the -71.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a camera and accessory mounting device that is easy to aim at the insertion position, easy to attach and detach, and has high positioning accuracy.

Means for Solving the Problem> In order to achieve the two-pronged object, the invention provides a method for detachably attaching the accessory to the camera by sliding and fitting the accessory-side mounting part into the camera-side mounting part. 1. A mounting device for a camera and accessories, wherein the camera-side mounting portion (1) includes a camera-side vertical positioning portion (1) that determines the vertical position of the accessory (1) with respect to the camera; It has a camera-side horizontal positioning part that determines the horizontal position with respect to the camera, and the accessory mounting part is fitted with the camera-side vertical positioning part to determine the vertical position of the accessory. a vertical positioning part; and an accessory-side horizontal positioning part that fits into the camera-side horizontal positioning part to determine the horizontal position of the accessory; The device is characterized in that the width of the direction positioning portion, the accessory-side vertical positioning portion, and the accessory-side horizontal positioning portion at the front in the mounting direction is narrower than the width at the rear in the mounting direction.

<Operation> The accessory mounting part is slid and inserted into the camera side mounting part. Then, the camera-side horizontal positioning part of the camera-side mounting part is fitted with the accessory-side horizontal positioning part of the accessory-side mounting part, and the horizontal position of the accessory is determined. At the same time, the camera-side vertical positioning part of the camera-side mounting part is fitted with the accessory-side vertical positioning part of the accessory-side mounting part to determine the vertical position of the accessory.

At that time, the width of the camera-side horizontal positioning section, camera-side vertical positioning section, accessory-side horizontal positioning section, and accessory-side vertical positioning section at the front in the mounting direction is narrower than the width at the rear in the mounting direction. Therefore, when inserting the accessory-side attachment part into the camera-side attachment part, it is easy to aim the insertion position, easy to attach and detach, and high positioning accuracy can be obtained.

<Example> Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments.

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 above-mentioned strobe device S connects the strobe foot SH, which is an accessory-side mounting part provided at the bottom, to an accessory shoe C8, which is a camera-side mounting part provided at the top of the camera body C, for example, from the back of the camera body S to the front. It is attached to the camera body C by sliding it toward the camera body C and inserting it. The strobe device S is provided with an auxiliary light projection device AL that projects auxiliary light for automatic focus detection.

Figure 2 shows the accessory shoe C fitted with the strobe device S attached to the camera body C.
FIG. 3 is a sectional view of the accessory shoe C8 and strobe foot SH in the direction perpendicular to the optical axis of the camera, and FIG. 3 is a sectional view of the accessory shoe C8 and strobe foot SH 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 configuration and fitting operation of the accessory shoe C8 and the strobe foot SH will be described in detail with reference to FIGS. 2, 3, and 4.

In FIG. 2, the accessory Shiko C8 is a Tacho-11 strobe device S integrally formed of plastic.
electrical terminal 2 for transmitting and receiving signals, etc., a strobe power terminal 6 for supplying strobe power, camera exterior members such as the top cover 4. and a bottom plate 3 disposed between the shoe l and the exterior member 4. The strobe foot S) [ also 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 14 that can also be slid up and down, and It is roughly constituted by a pressing plate 11 that serves as a guide for the movable contact I2.

First, the accessory shoe C8 will be explained in detail. The shoe l has a generally T-shaped cross-sectional shape with an eaves portion at the top, and is inserted from the inside of the exterior member 4 through the reinforcing plate 5 and the bottom plate 3 by, for example, four screws 9 (only two are shown). The corners are fixed to the exterior member 4. The strobe device S of this embodiment is a compact strobe device S of a type that does not have a power source on the strobe device S side and shares the power source of the camera body C. This strobe device S includes a lower surface 1b of the eaves portion of the shoe 1 having a substantially T-shaped cross section.
, a hotline P is installed at the position of the exterior member 4 facing lb.
(+) and power ground PC] - A power supply terminal 6 for the robot is provided, and when the strobe device S is attached to the camera body C, the strobe power Δ! :I terminal 6 and movable power supply terminal I
4 so that it will connect automatically. 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 above-mentioned power supply terminal 6 for the strobe car 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. Naturally, this strobe power supply terminal 6 is fixed to the exterior member 4 by compression and contraction, and a lug plate 7 for soldering is connected to the lower end thereof. 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 (■) and PG) are connected to the Sony PC as shown in Figures 5(a) and 5(b) to prevent them from being short-circuited by hands or other conductive objects. They are separately arranged at the lower part of the eaves part (indicated by X and Y) on both sides of the base of the 1. Above Sony 1. If the bottom plate 3 and the exterior member 4 are made of an insulator such as Plus Deck, the electrical terminal 2 and the strobe power 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 with a concave portion sandwiched between the convex portions 4b provided on the exterior member 4, but as shown at 4°, the strobe light is not provided with a convex portion on the exterior member. Even if the power supply terminal 6 is actively opened, there is no fear that it will be accidentally touched because the power supply terminal is under the eaves.

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), the electrical terminals 2 are arranged in two rows in order to prevent the electrical terminals 2 from short-circuiting due to water, sweat, dust, etc. and to improve reliability. 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 la for horizontal positioning provided at the center of the upper surface of the Sony 1. As shown in FIG. 4, this rear end 1a communicates with the outside. in this way,
By providing the electrical terminal 2 in the groove la that is wide enough that a human finger cannot fit into it, the electrical terminal 2 is prevented from being directly touched by the hand.

Signal transmission between the camera body C and the strobe device S in a camera of the type that supplies power to the strobe device S from the camera body C side as described above 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 bipedal foot body 10 is
It has foot portions 10b and IOb that fit between the lower surfaces 1b and Ib of both eaves portions of the Sony I integrally formed of plus deck and the bottom plate 3. The lower surface 10c of this foot portion 10b, the bottom plate 3, and the foot portion lOb
Vertical positioning is performed using the upper surface 10e and the lower surface 1b of the eaves of the Sony I as will be described in detail later. At the lower center of the foot body 10, there is a protrusion 1 for horizontal positioning that fits into a groove 1a provided on the upper surface of the shoe 1.
0a is provided. Horizontal positioning is then performed using both side surfaces of the groove 1a and the convex portion 10a, as will be described in detail later.

A movable contact 12 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 strobe device S is attached, the electrical terminal 2
The lower surface of the movable contact 12 slides over the movable contact 12 for self-cleaning, and the electric terminal 2 and the movable contact I2 can reliably contact each other to transmit signals. The holding plate 11 is a plate that fixes the upper end of the spring 13 and guides the movable contact 12, and is fixed to the foot body 10 with screws 20.

Furthermore, in the case of a strobe device S that is supplied with power 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. Similar to the case of the movable contact 12, this movable power supply terminal I4 is always urged downward by a spring 15 whose upper end is fixed by a presser plate +1, and protrudes from the lower surface of the foot portion Job as shown in FIG. It looks like this. By doing this, when the strobe device S is attached, the lower surface of the movable power terminal 14 slides on the strobe power terminal 6, thereby self-cleaning.
The strobe power supply terminal 6 and the movable power supply terminal 14 can reliably come into contact with each other. The stop plate 16 is a member for determining the lowest position of the movable power supply terminal 14.

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. As shown in FIG. This lock lever 21 is always urged downward by a lock spring 17. And strobe device S
When the attachment is completed, the lock member 21a provided at the tip of the lock lever 21 is inserted into the lock groove 1d provided in the groove 1a, and the strobe device S becomes locked. At this time, the locking member 21a slides on the separation strip 1c, so that the electrical terminal 2 is not disturbed. On the other hand, if you want to remove the strobe device S, press the lock release button! Press 9. Then, one end 18b 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 biasing force of the spring 17, and the lock member 21a is moved upward into the lock groove 1.
separated from d. Therefore, the strobe device S can be slid and separated from the camera body C. In FIG. 3, the lock release button 19 is attached to the rear of the strobe foot SH, but when removing the strobe device S from the camera body C, the lock release button 19 is placed at a position where the thumb, middle finger, and ring finger naturally come into contact, for example, as shown in FIG. to SL
If the lock release button 19 is attached to the position shown by , it becomes easier to separate the strobe device S.

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 by both sides of the 'IWtIa and the convex portion 10a, as described above. The above TfIjl
a' (and the convex portion 10a) is located at the front end (as shown in FIG.
The widths a and α on the lens side are narrower than the widths i and β on the rear end, respectively (i.e., a < b and α < β), and there is a taper between them. ing. Therefore, the length for positioning may be a small distance (for example, 1 to 2 mm) both forward and backward. That is, the horizontal positioning is not carried out over the entire length of the groove 1a, but only by a small distance between the front and rear parts of the groove 1a, at the final stage of installation.

Therefore, the strobe device S can be easily attached and detached without being caught due to friction between the side surface of the groove 1a and the side surface of the convex portion 10a while the strobe device S is attached, and the feel when attached is also excellent. In addition, as mentioned above, since the fitting accuracy is improved by ensuring reliable fitting within a small distance, the distance required for horizontal positioning is small and the processing accuracy is 1VV. Another advantage is that the width a of the front end of the protrusion 10a is narrow and the width a of the protrusion 10a is narrower than the width a of the rear end of the protrusion 10a.
Since the width of the insertion opening 0a is narrower than that of the insertion opening 0a, it is easy to aim and insert the strobe device S when attaching it to the camera body 0.

Manoko, the vertical positioning is like a double row: J
-1's lower eaves 1b, Ib and the upper surface of the foot part 1]Oe, 1Oe. As shown in FIG. 6 (the sectional view taken along the arrow 8-Δ in FIG. 2 and FIG.
.

, a rear portion 1b, and a slope portion 11) 3 located between the two. And the lower surface 1 b of the eaves part, I
The dimensions of the foot part 10b inserted between the foot part 10b and the bottom plate 3 are the thickness of the front part (corresponding to 1111 on the lower surface of the eaves)
The rear portion of J (corresponding to Ib on the lower surface of the eaves) is thicker (thinner than L (i.e., cod). Therefore, as in the case of horizontal positioning described above, vertical positioning is The short distance between the top and rear of the front part of the foot portion 10b makes it easy to insert and remove at the final stage of installation, and there is no catch during installation. It has the effect of being there.

Here, as shown in FIG. 6, the length l of the convex portion 10a for horizontal positioning 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 performed by the length t++), and then the foot portion 10b and IOb are connected to the eaves portion 1b.
, Ib and the bottom plate 3, making it easy to attach the strobe device S. At this time, the lower surface 10X of the foot body 10 first comes into contact with the upper surface IX of the foot I (see FIG. 6). However, since the lower front end 10y of the foot portion 10b 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 10 and the upper surface IX of -1. A gap is created between them. therefore,
Thereafter, a gap ε can be maintained between the bottom surface 10X of the foot body 10 and the top surface IX of the Sony I.
No scratches on surface 1x (-1), foot part 1
ON; I Fit smoothly.9 Next, the amount of play when attaching the strobe device S to the camera body C will be explained in detail.

In FIG. 7, assuming that the strobe foot width is the strobe foot width, the horizontal positioning length is M, and the gap amount is δ, the play amount (horizontal rotation amount) 0 can be determined as follows.

cos(θ0−θ) = cosθ. 10δ/M-sin
O6-1→(67M)'cos(θ.-α)-(A) However, tanα-δ/M, α<0 Here, if δm1n=0.2mm and M=I 8mm, δ/M= O, OI 1. ++(67M)2ξ1
Therefore, the janθ valve δ/M. Therefore, the amount of backlash θ becomes smaller as δ becomes smaller and M becomes larger, and approximately 6
It is determined by the size of 7M.

Next, consider the influence of the strobe foot width I.

When both sides of equation (A) are differentiated with 61M constant, it becomes d(3/dO, <O, and it can be seen that the play amount θ decreases as Oo increases, that is, L decreases.

Therefore, for horizontal positioning, the horizontal positioning length M should be made longer and the strobe foot width L (Zunaitsuchi,
The horizontal positioning width) may be narrowed.

Therefore, in this embodiment, the camera side vertical positioning section (i.e., the lower surface 1 b of the eaves section of the Sony 1
, 1rItIa, which is a horizontal positioning part on the camera side, is provided at the center of the upper surface of the saw I on the inner side,
The 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, approximately 4 mm
L, its length is made as long as possible (wood, about 10 mm in the example) to reduce the amount of play in the horizontal direction and to obtain high positioning accuracy. Further, by narrowing the width of jpj Ia in this manner, the electric terminal 2 provided in the groove la does not come into contact with a finger or the like as described above.

Further, as described above, the width a of the front end of the groove 1a is made slightly narrower than the width of the rear end, and the thickness C of the front part of the foot part 10b is formed slightly thinner than the thickness d of the rear part, so that the strobe device S horizontal and vertical positioning at the final stage of installation by groove 1a and only a small distance between the front and rear of the foot fob? I try to do that. Therefore, it is easy to insert the strobe foot SH into the accessory ship p, -CS, and there is no catch when the strobe mount S is attached, making it easy to attach.

Further, as described above, the length l of the convex portion 10a for horizontal positioning is made longer than the length l of the foot portion 10b for vertical positioning. Therefore, when the strobe device S is attached to the camera body C, 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 portion 1b, H+ and the bottom plate 3, so that the strobe device S can be easily attached. In this way, in this embodiment, Lu1l is set, but It<It may be set.

Therefore, according to this embodiment, the play of the strobe device S is extremely small even if it is not tightened and fixed with a nut etc. as in the conventional case, and the cross-sectional area of the electric terminal 2 is reduced to make the accessory shoe C9 and the strobe foot SH compact. It can be done. Furthermore, if the shoe l and the foot body lO are made of plus deck, the lower surface 1b3 of the eave of the shoe l can be better fitted to the foot part 10b by utilizing the elastic deformation of the plus deck, and vertical play can be minimized. It is also possible to reduce the cost compared to forming it from metal.

In this embodiment, the electric terminal 2 is placed in a groove Ia provided in the center of the upper surface of the shoe 1. Therefore, the electrical terminal 2 will not be touched carelessly by hands or the like.

Furthermore, since the movable contact 12 is always urged downward by the spring 13, self-cleaning when the strobe device S is attached opens the electric 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 arranged separately on both sides of the base of the shoe 1 at the lower part of the eaves of the shoe 1. are doing. 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 urged downward by the spring 15, the tip surfaces of the strobe power terminal 6 and the movable power terminal 14 may corrode or rust due to self-cleaning when the strobe device S is attached. It is also possible to maintain electrically stable contact. In addition, strobe device S
When attached to the camera body C, the strobe power supply terminal 6 is automatically connected to the movable power supply terminal 14, so the strobe
.

There is no need to separately provide a power supply means for the

In the above embodiment, a shoe L with an approximately 'I'-shaped cross section is provided on the camera body C side, but a strobe foot with an approximately T-shaped cross section is provided on the strobe device S side, and a strobe foot with an approximately T-shaped cross section is provided on the camera body C side. A mating accessory shoe may be provided. However, in order to make the accessory shoe of the camera-side attachment part relatively simple in shape and smaller in volume, the arrangement as in this embodiment is preferable.

Further, in each of the above embodiments, horizontal positioning is performed by both side surfaces of the groove 1a and the convex portion 10a, but it is also performed by the side surfaces 1d, 1d of the shoe l and the side surfaces 10d, 10d of the foot portion tob. You can. 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 horizontal positioning groove 1a and the convex portion 10a 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). Figure 8(b) shows the accessory shoe C of the strobe foot SH with a tapered part i*21b.
Fig. 8(c) shows a configuration in which a tapered portion is provided on the convex portion 40a to facilitate fitting of the strobe foot SH to the accessory shoe CS.

<Effects of the Invention> As is clear from the following, the camera and accessory mounting device of the present invention has a camera-side horizontal positioning part and a camera-side vertical positioning part of the camera-side mounting part, and the number of accessory examples τj. The width of the horizontal positioning part on the accessory side and the vertical positioning part on the accessory side in the front direction in the mounting direction is formed narrower than the width in the rear direction in the mounting direction, so that the number of accessories mentioned above is attached to the mounting part on the two-leg camera side. and the horizontal positioning part on the accessory side is fitted into the horizontal positioning part on the camera side to position the accessory horizontally, while the vertical positioning part on the accessory side is fitted in the horizontal direction positioning part on the camera side. Since the vertical positioning of the accessory is performed by fitting it into the positioning part, it is easy to aim the insertion position when inserting the accessory-side weir part into the camera-side mounting part, and the installation is easy. At the final stage, the accessory-side mounting part fits into the camera-side mounting part, making it easy to attach and detach, and positioning the accessory with high precision.
