Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motorized camera having a barrier member.

[0002]

2. Description of the Related Art In a conventional camera with a built-in motor having a barrier member, a motor for driving a lens barrel drive mechanism for adjusting the focal length of a photographing lens or a film feeding mechanism is provided inside the camera body (that is, in the camera body). (Inside the skeleton). That is, such a driving motor is arranged in a space below or on the left and right sides of the lens barrel (when viewed from the front side of the camera body) to drive the lens barrel, or below the spool chamber ( When viewed from the front side of the camera body), the film feeding mechanism is driven and the lens barrel is also driven through a transmission mechanism such as a gear mechanism.

However, in such a conventional camera, since the motor and its transmission mechanism are incorporated in the skeleton of the camera body, the motor and the transmission mechanism connected to the motor are provided in a small space inside the skeleton of the camera body. Since they must be assembled in a complicated manner, as a result, it is difficult to assemble and work the motor and the like at the time of assembling work or maintenance. Also, the camera body was inevitably upsized.

On the other hand, since the camera body skeleton accommodating the motor and its transmission mechanism is covered with the housing and the barrier member is provided in front of the housing so as to project, an unnecessary space is formed around the barrier member. In addition, it often happens that the barrier member is inadvertently opened when the camera is not used.

An object of the present invention is to provide a camera with a built-in motor that is small in size, excellent in operability, and easy for maintenance work even when a barrier member is provided in a camera having a lens barrel driving mechanism or a film feeding mechanism. To provide.

[0006]

In order to solve the above problems, a camera with a built-in motor according to the present invention comprises a housing, a photographing optical system provided at the center of the front surface of the housing, and the photographing optical system on both sides of the photographing optical system. A spool chamber and a cartridge chamber formed in the housing, and sliding between a closed position that is slidable in front of the housing and covers the photographing optical system, and an open position that is in front of one of the two chambers. A possible barrier member, and the motor is arranged between the other of the chambers and the front surface of the housing located at the other of the chambers. In addition to this, the front surface of the barrier member in the closed position and the front surface of the housing in front of the motor may be substantially flush with each other.

[0007]

According to the present invention, the motor is removed from the inside of the skeleton of the camera body, and the step is formed by the barrier member and the spool chamber or the cartridge chamber (that is, the step formed by the front surface of the barrier member and the front surface of the skeleton of the camera body). By externally attaching a motor, etc., assembly and maintenance work can be done simply by removing the housing part.
Further, since the position where the motor is externally attached is a step portion formed by the barrier member and the spool chamber (or the cartridge chamber), the space can be used without waste.

1 and 2 are views showing an embodiment of the present invention.

FIG. 1 is a cross-sectional view of a camera 20 with a built-in motor as seen from above, and a photographic optical system 1 at the center of the front of the camera 20 is held by a lens barrel portion 5. A lens barrel driving means including a cam barrel is provided on the outer circumference of the lens barrel 5, and the lens barrel driving means slides the photographing optical system 1 in the optical axis direction with respect to the skeleton 6 of the camera body. It is configured to move.

The skeleton 6 of the camera body has a cartridge chamber 3 and a spool chamber 4 at both ends thereof, and a lens barrel 5 is sandwiched between the two chambers 3 and 4. . Further, an aperture 7 is formed in the skeleton of the camera body on the rear side of the lens barrel 5. A back cover 8 is provided on the rear side of the aperture 7, and the back cover 8 is rotatably supported by a shaft portion 6a provided in a part of the skeleton 6 of the camera body.

Further, the outer periphery of the skeleton 6 of the camera body is covered with a housing, that is, a cover 9, except for the photographing optical system 1 and other external members (a finder, etc.).

A full barrier 11, which is a barrier member, is provided in front of the photographing optical system 1, and is slidably attached to the front of the housing, that is, the cover 9. In this state, the full barrier 11 is in the closed state (closed position A), but when the full barrier is moved leftward on the left front surface 9a of the cover 9, the full barrier 11 becomes the open state indicated by the phantom line (the open position). Position B). That is, this full barrier is slidably engaged with the cover 9 between the closed position A and the open position B.

A motor 10 is arranged to the right of the full barrier and in front of the spool chamber. The motor 10 is fixed to the front surface of the skeleton 6 of the camera body which is the front wall of the spool chamber. Therefore, the above-mentioned lens barrel driving means (not shown) can be driven.

On the further right side of the motor 10, there is a main capacitor 1 in the space formed by the thickness of the motor 10 and the rounded portion at the front right corner of the spool chamber 4.
4 is fixed. This main capacitor 14 stores the electric charge necessary for causing the strobe 15 (FIG. 2) to emit light.

The right front surface 9b of the cover 9 is arranged so as to cover the motor 10 and the main condenser 14. As a result, the right front surface 9b of the cover and the front surface 11b of the full barrier 11 are substantially in the same plane. In addition, this right front 9
b and the front surface 11b of the full barrier do not necessarily have to be in the same plane, and the right front surface 9b of the cover may slightly project forward in accordance with the structure of the motor 10 or the like. By doing so, the holding of the camera at the time of shooting can be improved.

FIG. 2 is an external view of the motor-embedded camera 20 of this embodiment as seen from the front. In this case, unlike the state of FIG. 1, the full barrier 11 is not in the closed position but in the open position. The front surface 11b of the full barrier 11 has a full barrier 11
A handle 11a for sliding the opening and closing positions is provided.

The photographing optical system 1 described above is arranged in the center of the front surface of the camera, and the finder optical system 2 is arranged above it. Therefore, the full barrier 11
When is moved rightward to the closed position, the finder optical system 2 and the photographing optical system 1 are covered and protected by the full barrier 11.

A strobe light emitting section 15 is provided on the upper right side of the front surface of the camera 20. An electric circuit or the like of the strobe light emitting portion may be arranged behind the strobe light emitting portion and above the spool chamber, and an internal mechanism of an external operation member (not shown) such as a release button of the camera 20. May be placed.

The spool chamber 4 at the right end of the camera 20
The main capacitor 14 described above is arranged in front of.

Further, the motor 10 is arranged in front of the spool chamber and on the left side of the main condenser 14 as described above.

Further, in the case of the present embodiment, a reduction system 12 is provided below the motor 10. The motor 10 can drive not only the lens barrel drive mechanism but also the film feeding system 13 provided on the bottom surface of the skeleton 6 of the camera body.

The speed reduction system 12 and the film feeding system 13 are not necessary in a camera that does not perform automatic winding. Further, as another embodiment, another motor is provided at the position of the speed reduction system 12 so that the film feeding system 13 is connected to the motor 1.
It may be configured to be driven separately from 0.

[0023]

According to the present invention, as already described,
The space created by the attachment of the full barrier can be used effectively. Especially, because the motor is placed in front of the spool,
The motor is close to both the lens barrel drive mechanism and the film feeding mechanism, and the arrangement for driving these mechanisms can be relatively simple.

Furthermore, by disposing the motor outside, the work of assembling and maintaining the mechanism such as the motor becomes easy.

Further, at the closed position of the full barrier, it is possible to eliminate the step between the front surface of the housing and the front surface of the full barrier, and it is possible to prevent the full barrier from being opened accidentally when the camera is housed in the case.
