Abstract

PROBLEM TO BE SOLVED: To restrain the increase of the dimension in an up-and-down direction and a lateral direction of a camera though the thickness of the camera from a lens barrel to a holding member for holding parts such as a battery and a capacitor for strobe light emission is increased by arranging the holding member on the back side of a pressing plate. SOLUTION: The holding member 12 is arranged on the back side of the pressing plate 11 and integrally formed on the plate 11. A battery chamber 20 housing the battery 8 and a capacitor holding part 19 holding the capacitor for strobe light emission 9 are formed in the member 12. The plate 11 on which the member 12 is integrally formed is fixed on a camera main body 21 at four spots by machine screws. The member 12 fixed with the plate 11 on the main body 21 is arranged to be opposed to a range from a position near to the aperture side of a cartridge chamber 17 to a position near to the aperture side of a winding chamber 15 on the back side of the plate 11. By such arrangement, the increase of the dimension in the up-and-down direction and the lateral direction of the camera is restrained though the thickness of the center part of the camera, that is, the part from the lens barrel 2 to the member 12 is increased.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera having a battery storage room and a condenser for strobe light emission, and more particularly to a camera suitable for high-magnification zoom.

[0002]

2. Description of the Related Art In recent years, a camera that adopts a retractable type lens barrel structure that can be telescopically extended and retracted so that the lens barrel can be collapsed when carrying the camera has become mainstream. . However, in the above-described camera, the overall length of the photographing lens increases as the zoom magnification of the photographing optical system increases, so that the thickness of the camera tends to increase even if the lens barrel is collapsed. is there.

In order to reduce the thickness of the lens barrel in the retracted state as much as possible, it is necessary to increase the number of steps of the lens barrel. However, when the number of steps is increased, the diameter of the lens barrel increases. When such a lens barrel structure is adopted, the outer diameter of the lens barrel becomes larger than the aperture screen width, so that the distance between the film cartridge chamber and the spool chamber becomes large, and a battery or a strobe is provided on the side of the camera body. By arranging a large-sized component having a relatively large volume such as a condenser for light emission, the width of the camera is increased, and the camera has a large projection area from the front.

Therefore, in order to make the width of the camera as small as possible, a battery, a condenser for strobe light, and the like are disposed behind the spool chamber or the patrone chamber (see Japanese Patent Application Laid-Open No. 7-209739). (See Japanese Patent Application Laid-Open No.
Japanese Patent Application Laid-Open No. 09-844) and a camera in which a battery is disposed in a back cover (see Japanese Patent Application Laid-Open No. 6-82890) have been proposed.

[0005]

In the cameras described above and above, a battery for operating the camera circuit, a condenser for strobe light emission, and the like are arranged on the rear or lower surface of the cartridge chamber or spool chamber. Although the lateral width of the camera can be reduced, the thickness of the left and right grip portions is increased, so that it is difficult to hold the camera and the vertical size of the camera is increased.

In the above-mentioned camera, the battery is arranged in the back cover, but the condenser is arranged in the grip portion, so that it is difficult to hold the camera.
There is a disadvantage that portability is deteriorated.

On the other hand, since the battery is to be loaded and unloaded by the photographer, it is necessary to provide a dedicated battery chamber so that loading and the like can be performed easily. Further, in order to prevent a terminal portion such as a capacitor from being damaged by vibration or the like, a holding structure for securely fixing the terminal portion to the camera is required.

Accordingly, in the present invention, the holding structure of large parts such as a battery and a capacitor for strobe light emission is laid out so that the vertical size and the horizontal size of the camera can be made as small as possible and the grip portion of the camera is not thickened. The purpose is to provide a camera that has been developed.

[0009]

In order to achieve the above-mentioned object, the present invention has a pressure plate disposed to face an aperture and a holding member for holding components such as a battery and a strobe light emitting capacitor. In the camera, the holding member is disposed on the back side of the pressure plate.

More specifically, the holding member is disposed on the rear side of the pressure plate in a range substantially opposed to the aperture, in other words, from a position near the aperture side end of the cartridge chamber to a position near the aperture side end of the spool chamber. It is arranged in a range opposite to the range up to the position.

Although the thickness of the camera from the lens barrel to the holding member increases, it is possible to suppress an increase in the vertical and horizontal dimensions of the camera. Moreover,
Since at least a part of the part of the camera body where the cartridge chamber and the winding chamber are formed projects outward from the holding member and the camera shape can be set so that this part becomes a grip part, the grip part Can be prevented from increasing in thickness.

In the above invention, the holding member and the pressure plate may be formed integrally or separately. By integrally forming, the number of parts can be reduced. In addition, by forming them separately, it is possible to make the mounting position of the pressure plate and the mounting position of the holding member different in the camera body, and even if an external force is applied to the holding member, the pressure plate is deformed by the external force. Can be avoided.

Here, in a so-called APS camera (a camera in which loading is automatically started just by loading a film cartridge in a film storage state into a cartridge chamber), an openable / closable back lid needs to be provided on the back of the camera. Therefore, the pressure plate is fixed to the camera body. In such an APS camera, when batteries and capacitors are arranged on the back side of the pressure plate, and when the battery chamber and the capacitor holding structure are configured by using an exterior member of the camera, it is necessary to repair the camera. When the exterior member is removed, the workability becomes very poor. That is,
At the time of repair work, each function of the camera must operate normally even when the exterior member of the camera is removed.If the battery compartment and the capacitor holding structure are provided on the exterior member, the exterior member side and the camera body side It is necessary to keep the electrical connection between them and a lead wire, so that the repair workability is deteriorated and the assemblability is also deteriorated.

Therefore, by providing the holding member separately from the exterior member of the camera and mounting it on the camera body, it is possible to maintain a state in which the camera can be operated even when the exterior member is removed for repair of the camera or the like. Thus, repair workability and assemblability can be improved.

The strobe device 3 is held by the hinge portion 6 of the exterior cover 1 so as to be rotatable about 90 degrees from the state shown in FIGS. 1 and 4 to the state shown in FIGS. When raised to the state shown in FIGS. 2 and 3,
The light emitting unit 7 faces forward, and it becomes possible to irradiate the subject with strobe light.

The AF device 5 is arranged such that the front surface of the device is exposed when the flash device 3 is flipped up.

In a camera having such an external configuration,
From the state of FIG. 1, the main switch (not shown) of the camera is
When N is reached, the lens barrel is extended forward, the photographing lens is set to the wide position, and the locking of the strobe device 3 is released, and the stroboscopic device 3 is lifted upward by a spring (not shown), and the state shown in FIG. Becomes

When the strobe device 3 is flipped up, the front surface of the AF device 5 is exposed, so that AF can be performed. When a zoom operation switch (not shown) is operated, the lens barrel is extended as shown in FIG.
The taking lens is set to the tele position.

5 to 7, reference numeral 21 denotes a camera body covered by an exterior cover, 11 denotes a pressure plate, and 12 denotes a holding member disposed on the back side of the pressure plate 11. An aperture 14 is formed in the camera body 21 at a position facing the lens barrel 2. A cartridge chamber 17 in which a film cartridge 16 is loaded and a film unwound from the film cartridge 16 are sandwiched between the apertures 14. A hoisting chamber 15 for storing (winding with a spool or storing in a wound state without a spool) is formed.

The holding member 12 is formed integrally with the pressure plate 11. In the holding member 12, two battery chambers 20 for storing the batteries 8 and a capacitor holding portion 19 for holding the strobe light emitting capacitor 9 are formed. The pressure plate 11 in which the holding member 12 is integrally formed
Are fixed to the camera body 21 at four places by screws 22.

As shown in FIG. 5, the holding member 12 fixed to the camera body 21 together with the pressure plate 11 is provided on the rear side of the pressure plate 11 from a position closer to the aperture of the cartridge chamber 17 toward the aperture of the winding chamber 15. It is arranged so as to face the range up to the position.

Reference numeral 13 shown in FIGS. 4 and 5 is a battery chamber cover provided on the outer cover.
3, the battery 8 is inserted into the battery compartment 20 or the battery compartment 20 is opened.
The battery 8 can be taken out from the battery.

Reference numeral 10 shown in FIG. 6 is a display LCD for displaying a film counter, data, and the like.

According to the camera of the present embodiment described above, the holding member 12 for holding a relatively large-sized large component such as the battery 8 and the strobe light emitting capacitor 9 is substantially attached to the aperture 14 on the rear side of the pressure plate 11. Since they can be arranged in the opposing range, the thickness of the camera in the central portion, that is, from the lens barrel 2 to the holding member 12 increases, but it is possible to suppress an increase in the vertical and horizontal dimensions of the camera. In addition, the outer portion of the portion of the camera body 21 where the cartridge chamber 17 and the winding chamber 15 are formed protrudes outward beyond the holding member 12, and a grip portion is formed by the outer cover 1 covering this portion. Therefore, an increase in the thickness of the grip portion can be prevented, and the ease of holding can be ensured.

Therefore, even if the lens barrel 2 having a long overall length employing a high magnification zoom lens having a long focal length on the telephoto side is incorporated, the thickness direction at the center of the optical axis of the camera is not small, but the vertical and horizontal directions are small. Because it is small, portability is good,
It is possible to realize a camera having good hold characteristics at the time of shooting.

Further, in this embodiment, the holding member 12 is provided separately from the outer cover 1 and is attached to the camera body 21 together with the pressure plate 11, so that even when the outer cover 1 is removed for repairing the camera, the camera is mounted. An operable state can be maintained, and repair workability and assemblability can be improved.

In this embodiment, since the holding member 12 is formed integrally with the pressure plate 11, the holding member 12 and the pressure plate 1 are formed integrally.
1, and the number of parts can be reduced, and assemblability and repair workability can be improved.

(Second Embodiment) FIG. 8 shows a second embodiment of the present invention.
4 illustrates a relationship among a camera body, a pressure plate, and a holding member of the camera according to the embodiment. Note that the basic configuration of the camera according to the present embodiment is the same as that of the camera according to the first embodiment, and thus the same reference numerals are given to the common components, and description thereof will be omitted.

In the camera of the first embodiment, since the holding member 12 is formed integrally with the pressure plate 11, repair workability is improved. However, when an external force is applied to the holding member 12 from the outside of the camera, When pressure is applied to the battery terminal member when the battery 8 is inserted into the battery chamber 20, the pressure plate 11 may be deformed and affect the film feeding.

Therefore, in the present embodiment, the pressure plate 11 and the holding member 12 are separated from each other, and the pressure plate 11 is independently fixed to the camera body 21, and the holding member 12 is avoided from the fixing position of the pressure plate 11 in the camera body. Position (camera body 21
(The upper and lower positions of the pressure plate fixing position) are screwed at four locations using screws 23.

Thus, even if a load such as an external force is applied to the holding member 12, the pressure plate 11 can be prevented from being deformed.

In each of the above embodiments, the holding member 12
Although the battery 8 and the strobe light emitting capacitor 9 are mentioned as the large parts to be held in the above, other large parts may be held.

[0035]

As described above, according to the present invention,
Since the holding member that holds components such as batteries and flashlight condensers is located on the back side of the pressure plate, the thickness from the lens barrel to the holding member of the camera increases, but the vertical and horizontal dimensions of the camera The increase can be suppressed.

In addition, the holding member is positioned on the rear side of the pressure plate in a range substantially opposite to the aperture or in a range from a position near the end of the cartridge chamber near the aperture to a position near the end of the spool chamber near the aperture. If it is arranged in the camera body, at least a part of the part where the cartridge chamber and the winding chamber in the camera body are formed can be made to protrude outward from the holding member, and the camera shape is formed so that this part becomes a grip part. Can be set. For this reason, it is possible to prevent an increase in the thickness of the grip portion, and to improve the holdability of the camera.

If the holding member and the pressure plate are integrally formed, the number of parts can be reduced, and the assembling property and repair workability can be improved.

Further, if the holding member and the pressure plate are formed separately, the mounting position of the pressure plate and the mounting position of the holding member in the camera body can be made different from each other. This can prevent the pressure plate from being deformed.

Further, if the holding member is provided separately from the exterior member of the camera and is attached to the camera body, the camera can be operated even when the exterior member is removed for repairing the camera, etc. Workability and assemblability can be improved.
