Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a focal plane shutter camera, and more particularly, to an arrangement structure of a battery, a driving motor and an electronic flash capacitor in a focal plane shutter.

[0002]

2. Description of the Related Art Conventionally, in the process of downsizing a camera, the size of the camera is inevitably determined by how relatively large components are arranged in a body. In particular, in the case of a camera incorporating an electronic flash, the size of the camera is substantially determined by the arrangement of three relatively large types of cylindrical parts: a built-in motor for driving mechanical components, a flash charging capacitor, and a battery. It is no exaggeration to say. Further, in a camera with interchangeable lenses, a mount for mounting a lens is provided on the front of the camera body, and the distance between the mount and the focal plane shutter is set to a substantially predetermined value. Therefore, the size in the front-back direction is substantially determined.

On the other hand, as an arrangement structure of these parts, conventionally, for example, a structure in which a battery or a capacitor is arranged above and below a film between a spool chamber and a cartridge chamber substantially in parallel with an optical axis (first structure), a body There has been proposed a structure in which a battery is arranged at the end on the grip side (second structure) or a structure in which the battery is arranged below the lens barrel (third structure).

In the first structure, when applied to a focal plane shutter camera, a battery or a capacitor is disposed above or below the focal plane shutter. It is necessary to add the diameter of the battery or capacitor to the minimum value of the height of the camera, and the camera becomes larger in the height direction. In particular, in the case of a camera using a small and large-capacity battery, since the diameter of the battery is larger than that of a capacitor or a motor, arranging the battery in this position is a great limitation on miniaturization of the camera.

In the second structure, it is necessary to add the diameter of the battery to the minimum value of the width determined by the width of the focal plane shutter and the diameter of the cartridge and the spool, so that the camera becomes larger in the width direction. Furthermore, in the third structure, when applied to a general auto-focus single-lens reflex camera as a focal plane shutter camera, the battery is disposed further below the auto-focus module disposed below the lens barrel,
The camera grows in height.

[0006]

As described above, in the arrangement proposed in the prior art, when applied to a focal plane shutter camera such as an autofocus single-lens reflex camera, the camera cannot be sufficiently reduced in size. There was a problem. Therefore, a technical problem to be solved by the present invention is to improve the arrangement of a cylindrical component for storing electric energy such as a battery and a capacitor for an electronic flash, a motor, and the like in a focal plane shutter camera, and to reduce the size of the camera. It is to plan.

[0007]

A focal plane shutter camera according to the present invention is provided with a photographing frame and a front frame disposed in front of the frame and close to one of the right and left sides of the frame. A focal plane shutter having a shutter control unit disposed therein, and a cartridge chamber and a spool chamber disposed on both left and right sides of the focal plane shutter, and in order to solve the above-described technical problem, a spool in the spool chamber is provided. At least one electric energy storage cylindrical component is disposed substantially along the optical axis direction in a space extending from above or below to the front of the shutter frame.

The cylindrical body part may be arranged not in front of the shutter frame of the focal plane shutter but in a space extending from above or below the spool to behind the interchangeable lens mount surface. It may be arranged in a space that extends from below to extend between the shutter frame and the interchangeable lens mount surface. In these cases, the cylindrical body component may be arranged at a position other than the front of the shutter frame of the focal plane shutter or the rear of the interchangeable lens mount surface as long as it is above or below the spool. As the cylindrical body parts arranged at these positions, a small-sized and large-capacity battery is particularly effective because of its diameter, but may be a capacitor if necessary.

When the film cartridge and the spool are compared, the height of the spool is lower. For this reason, it is easy to provide space above and below the spool in the body of the camera, so in that position, even if the diameter of the camera is larger than that of a motor or a condenser, such as a small large-capacity battery, It can be arranged without increasing the height dimension. Therefore, the size of the camera can be reduced as compared with the conventional arrangement. In general, a focal plane shutter camera is configured as a single-lens reflex camera, and a mirror box is provided in front of a frame of the focal plane shutter. Even if the camera is arranged so as to be oriented substantially along the optical axis in a space formed between the camera and the (front wall), the thickness of the camera does not increase.

Further, in the above configuration, the cylindrical body part is positioned forward of the shutter frame of the focal plane shutter at a position overlapping the upper end or the lower end of the shutter frame of the focal plane shutter when viewed from the front. It is preferable to arrange them. With such a configuration, the height dimension of the camera can be reduced by an amount corresponding to the overlapping of the shutter frame and the cylindrical body part, and thus the camera can be further miniaturized as a whole.

Further, in the above configuration, when the camera is an autofocus camera having an autofocus sensor module positioned below the center of the photographing frame and in front of the shutter frame, the cylindrical component is automatically moved below the spool. It is preferable to arrange on the side of the focus sensor module. Since the space on the side of the autofocus sensor module is generally dead space in many cases, the space can be effectively used by disposing the cylindrical body component at this position.

In the above-mentioned configuration, the camera is provided with a magnetic head for reading and writing magnetic information on a magnetic recording surface provided on a film, at a lower rear portion on a spool side of a frame of a focal plane shutter. In some cases, the cylindrical part may be located in front of the magnetic head or below the magnetic head. Because these parts also tend to be dead spaces,
With this configuration, the space can be effectively used.

When the cylindrical component is disposed in front of or below the magnetic head, a notch is provided at the lower end of the spool of the frame of the focal plane shutter, and the cylindrical component is provided with the notch. Can be located in the vicinity of the lower part. By doing so, the space in which the cylindrical body parts can be arranged under the spool is widened toward the center of the camera, which is effective when, for example, two cylindrical body parts are arranged.

When batteries are disposed above and below the spool as cylindrical parts, it is preferable that the drive motor be disposed vertically in the space in front of the shutter control section of the focal plane shutter or in front of the cartridge opening. This space is smaller than the space in which the battery is arranged, but since the motor has a smaller diameter than the battery, the camera can be arranged without increasing the thickness and width of the camera.

Further, in the above configuration, it is preferable to dispose a condenser in the spool. Since the size of the camera in the front-back direction and the width direction is already determined by the battery, there is no effect even if the diameter of the spool is slightly increased by the capacitor placed inside. Can be placed without it. In addition, in this arrangement, since the battery and the capacitor are close to each other, the efficiency of the flash electric system can be increased.

In this case, it is preferable to dispose a flash circuit on the side opposite to the battery with respect to the spool. As described above, a space is easily formed above and below the spool because the height is lower than the cartridge, so that the flash circuit can be arranged in a well-balanced manner on the side opposite to the battery with respect to the spool.

Further, in the above configuration, it is preferable to use a battery holder as a member for holding the battery, and to form a spool bearing for rotatably supporting one end of the spool in the battery holder. Furthermore, when a condenser is arranged in the spool, this spool bearing portion,
At least one of the capacitor supporting portions supporting one end of the capacitor can be formed. With this configuration, in addition to the effective use of space by arranging the battery below the spool, it is not necessary to separately provide a bearing member for the spool and a support member for the capacitor, so that the arrangement efficiency of components is increased.

[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a focal plane shutter camera according to the present invention will be described below with reference to FIG.
This will be described in detail with reference to FIG.

First, the first embodiment shown in FIGS. 1 to 3 will be described. FIG. 1A is a plan view of the body of the focal plane shutter camera, and FIG.
Is a front view. In the figure, reference numeral 1 denotes a focal plane shutter arranged in front of a shooting image frame, and a shutter control unit 1a arranged close to the left side of the image frame includes:
It is formed integrally with the flat shutter frame 1b. Reference numeral 2 denotes a spool chamber disposed on the right side of the focal plane shutter, and reference numeral 3 denotes a cartridge chamber disposed on the left side of the focal plane shutter.
And the cartridge chamber 3 are disposed on both left and right sides of the focal plane shutter 1.

Below the spool 4 in the spool chamber 2,
The battery 5 of the book is arranged in a direction substantially along the optical axis of a photographing lens (not shown) and slightly shifted back and forth. The left battery 5 is disposed forward of the frame 1b of the focal plane shutter 1 and rearward of the interchangeable lens mount surface 6 at a position overlapping the lower end of the frame 1b when viewed from the front. Left battery 5
Is inserted between the frame 1b of the shutter 1 and the mounting surface 6, so that the shape of the front cover of the camera body can be made natural without any protruding portions. This location is the frame 1 of the focal plane shutter 1.
Since this is a dead space beside the sensor module 7 for auto-focusing disposed in the lower front of the center of b, the space can be effectively used.

An electronic flash capacitor 8 is disposed in the spool 4, and a flash circuit board 9 is disposed above the spool 4. As described above, since the battery 5, the capacitor 8, and the flash circuit board 9 are arranged close to each other, the loss in the flash circuit can be reduced and the efficiency can be increased.

From the front of the shutter controller 1a of the focal plane shutter 1, the mouth 10 of the cartridge 10
The drive motor 11 is arranged in a space in front of “a”. If the motor 11 is arranged at this position, the shutter 1 and the mirror box 1
In addition to driving the main mirror provided in 2, the film is fed through the speed reduction mechanism 13 and the output switching mechanism 14 for initial feeding and rewinding of the film. Can be.
Further, if the motor 11 is used to lock the lid of the cartridge chamber 3 and eject the cartridge chamber member, the convenience of the camera can be improved.

Since this position is a vertically long and narrow space, it is suitable for arranging the motor 11 in this manner.
If necessary, the motor 11 and the condenser 8 can be arranged in reverse. However, in the case of the illustrated first embodiment, the left side of the figure (the grip side of the camera) has more driven members, so it is more reasonable to arrange the motor 11.
Furthermore, if the output of the motor 11 is configured to be guided also to the right side in the drawing, and the winding spool 4 is also driven,
The driving of the driven portion in the camera body can be covered by one motor, which is extremely efficient.

Reference numeral 15 denotes an electronic flash light emitting unit, 16 denotes a finder, and 17 denotes a magnetic head. Although not shown in detail, the finder 16 reflects the light reflected upward by the main mirror through the photographing lens several times toward the eyepiece window (not shown) and guides the light.
The inverted subject image is inverted by a relay optical system composed of several lenses so as to be a formed image. The magnetic head 17 reads and writes magnetic information on the magnetic recording layer provided on the film when the film is fed.

In the above configuration, the battery is arranged at a position below the spool 4 which is lower in height than the film cartridge 10 and easily provides an empty space in the camera body, so that the space in the height direction in the camera body is reduced. Since the camera is effectively used, the height of the camera can be prevented from increasing. In particular, the battery 5 is used for the focal plane shutter 1
Since the battery 5 is disposed at a position overlapping with the lower end of the frame 1b, the battery 5 can be disposed so as to be extremely close to the lower surface of the spool 4, and an excellent effect of miniaturizing the camera can be obtained.

Further, since the motor 11 is arranged in an empty space between the shutter control unit 1a and the mounting surface 6 and the condenser 8 is arranged in the spool 4, the thickness of the camera is not increased and the width is not increased. The required minimum size determined by the focal plane shutter 1, the cartridge 10, and the spool 4 can be obtained. Thus, according to the above configuration, it is possible to make the camera smaller than before.

FIG. 2 is a partially enlarged view of the spool chamber 2 side in the camera body, and FIG. 3 is an exploded perspective view of the spool chamber 2 side viewed from diagonally rear. Reference numeral 18 denotes a body structure of the camera body, and 19 denotes a battery holder for holding the battery 5. The main body structure 18 is usually formed by resin molding. In this case, it is difficult to form a complicated-shaped portion on the upper and lower wall surfaces of the semi-cylindrical spool chamber 2. For this reason, in order to provide a support portion for the condenser 8 disposed in the spool 4 in addition to the bearing portion for the winding spool 4, another member is required.

If the bearing 19a and the support 19b are formed in the battery holder 19 disposed at this position, not only can the space for the battery 5 be effectively used, but also the number of parts can be reduced. In this example,
The bearing portion 19a is formed by an annular convex portion fitted to the lower end of the spool 4, and the capacitor support portion 19b is formed by a circular concave portion formed on the inner surface thereof. 8 supports are possible. Reference numeral 19c denotes a battery terminal.

Next, a second embodiment shown in FIG. 4 will be described. In this example, two batteries 5 are provided above the spool 4.
The left battery 5 is disposed so as to enter between the shutter frame 1b and the mounting surface 6. Also, in this camera, unlike the first embodiment,
A pentagonal roof prism is used for the reversing optical system of the finder 16. For this reason, the right portion of the flash light emitting section 15 becomes a dead space, and the camera body has a configuration in which this portion is depressed. Since the other parts have basically the same configuration as the first embodiment, the description will be omitted by attaching the same reference numerals to those in FIG.

Even with this configuration, it is possible to prevent the height, thickness, and width of the camera from increasing. Further, if the battery 5 is arranged above, a continuous space is formed below the spool 8 to the grip side, so that the output of the motor 11 is reduced from the grip side to the spool 4.
It is easy to communicate up to. If the transmission of the motor output is performed in another place such as on the mirror box 12 or behind the pressure plate, the height of the camera can be reduced to reduce the size.

Next, a third embodiment shown in FIG. 5 will be described. In this example, the spool chamber 2 is disposed on the left side of the focal plane shutter 1, and the cartridge chamber 3 is disposed on the right side. Two batteries 5 are arranged in a space between the lower part of the spool 4 and the space between the shutter frame 1b and the mount surface 6 and slightly shifted back and forth in a direction substantially along the optical axis. The battery on the right is
It is sandwiched from the front and back by the shutter frame 1b and the mounting surface 6, and is sandwiched from the left and right by the shutter control unit 1a and the autofocus sensor module 7. By doing so, the lateral width of the camera is made smaller than when two batteries are arranged under the spool 4.

In this embodiment, two motors 11a, 1
1b, the first motor 11a is arranged in front of the shutter controller 1a, the second motor 11b is arranged in front of the cartridge opening 10a, and the speed reduction mechanisms 13a, 13b are arranged for each of the motors 11a, 11b. ing. The first motor 11a drives the shutter, the mirror, and the take-up spool 4. The second motor 11b opens and closes the light-shielding door of the cartridge, initially feeds and rewinds the film. It is designed to eject. Thus, the motor 11a,
By arranging the 11b separately, the driven bodies on the right and left sides of the camera can be driven separately, so that there is no need to connect both by a drive transmission system.

The condenser 8 is disposed in the spool 4 as in the above embodiments. In addition, cartridge 1
The magnetic head 17 is disposed above and to the left of the image frame when viewed from the front, and the output switching mechanism 14 is disposed below the cartridge in a relationship in which the positions of the spool 0 and the spool 4 are opposite to those of the above embodiments. Note that the flash 15 and the finder 1
6 has the same configuration as in the first embodiment.

This arrangement not only prevents the height, thickness, and width of the camera from being increased, but also provides a weight balance on the grip side of the camera by placing a heavy object on the grip side of the camera. Is obtained.

Next, a fourth embodiment shown in FIG. 6 will be described. This example is an example in which the capacitor 8 is arranged at a slightly lower position and the battery 5 is arranged on the spool 4 as compared with the third embodiment. Regarding the arrangement of the batteries 5, since the batteries 5 cannot be moved to the center in order to avoid interference with the shutter control unit 1a, the heights of the two batteries 5 are slightly shifted to increase the lateral width of the camera. Is prevented. The flash circuit 9 is arranged in a space formed below the battery 5 on the right side.

Since the other parts have the same configuration as the third embodiment, the description will be omitted by assigning the same reference numerals to the respective parts, but even with such a configuration, the same effect as in the third embodiment will be obtained. Is obtained.

Next, a fifth embodiment shown in FIG. 7 will be described. This example has the same configuration as that of the first embodiment except that the arrangement of the battery 5 and the shape of the shutter 1 and the magnetic head 17 are accordingly different, so only the different points will be described.

The shutter frame 1b has a notch at the lower right corner, and the left battery 5 is disposed below the notch 1c. The magnetic head 17 is smaller in the height direction than in the first embodiment,
Also penetrates below the magnetic head 17. Battery 5
Are arranged closer to the center on the front side of the camera (on the mount surface 6 side) than on the rear side (the shutter side), so that they are arranged slightly inclined with respect to the optical axis. Even with this configuration, it is possible to prevent the height, thickness, and width of the camera from increasing.

Next, a sixth embodiment shown in FIG. 8 will be described. This example is an example of a camera in which a photographing lens (zoom lens) is integrated with a body.
1. The arrangement of the cartridge 10 and the like is basically the same as that of the first embodiment. The difference is that the second motor 20 is provided for driving the built-in zoom lens 21 in the space where the right battery 5 is arranged in the third embodiment. Note that it is also possible to configure so that the lens is driven by switching the output of the first motor 11 without using the second motor 20. Then, another component can be arranged at the position of the second motor 20.

Next, a seventh embodiment shown in FIG. 9 will be described. In this example, two batteries 5 are arranged on both sides of the autofocus sensor module 7 along the optical axis direction. This arrangement is difficult when the autofocus sensor module 7 is large for multi-point distance measurement or the like, but when the autofocus sensor module 7 is small as in this example, the battery 5 is placed at this position. By arranging, a space can be made in the lower part of the spool chamber 2. Therefore, if the capacitor 8 is shifted downward by utilizing this allowance, the flash circuit board 9 can be arranged without difficulty, and the photometric sensor for automatic exposure (AE) 26
Also, it is possible to arrange a diopter adjusting mechanism 27 of the finder.

Reference numeral 28 denotes a tripod mounting screw portion. The other parts are basically the same as those in the first embodiment. Therefore, the description will be omitted by giving the same reference numerals to those in FIG. Even with this configuration, it is possible to prevent the height, thickness, and width of the camera from increasing.

In the first embodiment, since the battery 5 is arranged at a position relatively close to the exterior under the spool 4, the battery can be replaced by providing a battery chamber lid on the lower surface of the body. Can be done easily. For example,
As shown in FIG. 10A, which is a perspective view of the camera as viewed obliquely from the lower rear side, the lid 22 of the battery chamber can be slidable. In this figure, 23 is axis 2
Reference numeral 25 denotes a lid of a cartridge chamber which is rotatable around the reference numeral 4, and reference numeral 25 denotes an eyepiece window of a finder.

Further, the lid 22 of the battery compartment may be provided on the back of the body. In FIG. 10, (b) shows the lid 2 of the battery chamber.
2 shows an example in which an opening / closing door type is used. In this example, since the battery chamber cover 22 is provided on the back of the camera, there is an advantage that the battery can be replaced even when the tripod is attached to the camera, for example. FIG. 11 shows how the battery 5 is inserted and removed when the battery chamber lid 22 is configured as described above. In this case, since the inner battery 5 has entered the front of the shutter frame 1b, it cannot be taken out directly behind. However, as shown in FIG. 11A, the outer battery 5 is taken out first.
Next, the inner battery 5 can be taken out by shifting it to the outside. In addition, the loading of the battery 5 as shown in FIG.
The operation can be performed in the reverse order of the operation for removing. In addition, 2
9, 30, 31 indicate battery contacts.

When the battery 5 is arranged above the spool 4 as in the second embodiment, the battery can be replaced by changing the battery chamber cover 22 to the structure shown in FIGS. Is easy. In the case of (b), as in the case shown in FIG. 11, the outer battery in FIG. 4 can be taken out by first taking out the battery and then moving the inner battery out.

In the case of the arrangement of the third embodiment, for example,
As shown in FIG. 13, the battery and the cartridge can be easily exchanged by making the lid of the battery chamber slide and the lid of the cartridge chamber rotary. Furthermore, the battery chamber lid in the case of the fourth embodiment can be configured as shown in FIG. 14, and in the case of the fifth embodiment, the lid 22 of the battery chamber can have the two configurations shown in FIG. ,
Even with the configuration shown in FIG. 15, the battery can be easily replaced.

FIG. 16 shows the structure of the battery chamber cover 22 corresponding to the arrangement of the batteries in the seventh embodiment.
(A) shows a state where the lid 22 is opened, and (b) shows a state where the lid 22 is closed. As shown in FIG. 9, in this example, the tripod screw portion 28 is disposed behind the autofocus sensor module 7, so that the battery compartment cover 22 avoids the screw portion 28 and the two batteries 5 on both sides. It is configured to cover. Reference numeral 32 denotes a battery compartment, and the lid 22 includes claws 33 and 3
The battery chamber 32 can be closed by engaging the battery 4. On the other hand, a hole 35 is provided at the lower part of the autofocus sensor module 7 in the inner wall constituting the battery chamber 32 so as to adjust the position and posture of the sensor module 7 and to provide an electrical signal contact for inspection after completion. Used for 36. When the inspection is completed after completion, a seal 37 or the like is attached to this portion so that the hole 35 is closed. As shown in the drawing, the direction in which the battery is loaded can be indicated on the seal 37.
