Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a camera, and more particularly to an arrangement of substrates inside a housing in a camera having a plurality of circuit boards inside the housing.

[0002]

2. Description of the Related Art In recent years, electronic imaging means including an image pickup device such as a CCD for performing photoelectric conversion upon receiving a subject image formed by a photographing lens is provided, and a still image signal output from the imaging means is provided. And an electronic still camera (Electronic Still Cam) in which various kinds of information and the like accompanying the information are recorded on a predetermined recording medium by a predetermined recording means.
era; hereinafter, referred to as an electronic camera. ) Is widely spread.

In such an electronic camera, control is performed by an electric control circuit or the like to perform a photographing / recording operation or the like. For this purpose, a plurality of circuit boards on which a control circuit including various electric components and the like are mounted are arranged at predetermined positions inside the housing of the electronic camera.

[0004] In general, a substrate arrangement inside a housing of a conventional electronic camera is generally in a form as disclosed in, for example, Japanese Patent Application Laid-Open No. Hei 9-116796.

In the electronic camera disclosed in Japanese Patent Application Laid-Open No. Hei 9-116796, a plurality of circuit boards are arranged in the camera housing in a direction along the optical axis of the photographing lens. That is, a plurality of circuit boards are respectively arranged on a plurality of surfaces substantially orthogonal to the optical axis of the photographing lens, and the plurality of circuit boards are arranged inside the housing in a stacked form.

As described above, in the housing of a conventional electronic camera, by arranging a plurality of circuit boards so as to be stacked, the size of the electronic camera in the front-rear direction, that is, in the thickness direction becomes relatively short. This can contribute to downsizing of the camera housing.

On the other hand, a conventional electronic camera is provided with a so-called zoom lens unit configured to continuously change the magnification of a photographing lens within a predetermined range, and this zoom lens unit is integrated with a camera housing. Those that are arranged in a practical manner are generally put to practical use.

Conventionally, there has always been a demand for a high zoom ratio of a zoom lens in an electronic camera, and in recent years, a zoom lens having a zoom ratio exceeding 10 times has been generally put into practical use. In such a high-magnification zoom lens, the length dimension (total length) of the lens barrel in the optical axis direction is much longer than the entire length of a single focus lens or a low-magnification zoom lens. Is well known.

In general, in a high-magnification zoom lens, the number of optical elements constituting the zoom lens, that is, the number of lens elements increases, and a large-diameter optical lens is required to maintain a predetermined brightness or more. Elements (lenses) tend to be required. Also, there is a tendency that a large-sized driving mechanism, a driving motor, and the like for arbitrarily driving each of the plurality of lenses to execute the zooming operation and the focus adjustment operation are required.
Therefore, a high-magnification zoom lens generally tends to have a large size and weight as a unit.

On the other hand, in a conventional electronic camera, a so-called flash light emitting device for irradiating auxiliary illuminating light to a subject as necessary when performing a photographing operation is provided in a camera housing. The one with a built-in flash light emitting device is generally put to practical use.

When an electronic camera equipped with such a built-in flash light emitting device is compatible with a high-magnification zoom lens, the light emission amount of the flash light emitting device is compatible with a single focus lens or a low-magnification zoom lens. Needless to say, a larger amount of light is required as compared with the case of performing the above. Therefore,
Accordingly, components such as a power supply and a main capacitor used for causing the flash light emitting device to emit light also need to be large.

In a general electronic camera, a control circuit and the like for performing general operation control and the like of the camera and executing signal processing such as an image pickup signal acquired by an image pickup device are mounted. Circuit boards such as boards
It is desirable to secure a sufficiently large area, and it is also desirable that the outer shape be formed in a simple outer shape.

As described above, in the conventional electronic camera,
The size of the camera housing tends to be increased due to the adoption of a high-magnification zoom lens, an increase in the number of electrical components due to multifunctionalization, and the like.

On the other hand, a general electronic camera needs to be configured so that a user can carry it to an arbitrary place and easily use it at a place desired by the user when desired. Therefore, a demand for downsizing of a camera housing for the purpose of improving portability and the like has always been desired.

[0015]

However, in a camera in which a high-magnification zoom lens is integrally provided in a camera housing, conventional cameras as disclosed in Japanese Patent Application Laid-Open No. Hei 9-116796 are used. When the arrangement of the internal substrates is adopted, the overall length of the zoom lens unit itself becomes longer, so that the dimension in the thickness direction of the camera housing, that is, the direction along the optical axis becomes larger. Therefore, there is a problem that the camera housing itself becomes large. At the same time, the fact that the dimension in the thickness direction of the camera housing is increased, which is a factor that hinders the operability of the camera, has been made in view of the above points, and The purpose is to increase the area of a larger board by efficiently arranging a plurality of circuit boards arranged inside the camera housing in a camera having a high-magnification zoom lens integrated in the camera housing. It is possible to provide a camera which can secure the size of the housing while preventing the housing from being enlarged, and further improving the portability and reducing the size of the housing without impairing the operability.

The power supply strobe board 36 is arranged so as to secure a wider area with respect to the projection plane when viewed from the entire side or the rear side of the electronic camera 1, as viewed from the upper side or the lower side of the electronic camera 1. In this case, a larger area can be secured with respect to the projection plane.

In this case, in the electronic camera 1, since the photographing lens unit 10 is a high-magnification zoom lens, the size in the thickness direction of the camera housing, that is, the direction along the optical axis of the photographing lens. Is longer than those using a single focus lens or a low magnification zoom lens. Paying attention to this point, by arranging the power supply strobe board 36 on a surface substantially parallel to the upper surface or the lower surface of the housing as described above, a sufficient area is secured without increasing the size of the camera housing.

As described above, according to the first embodiment, in the electronic camera 1 including the photographing lens unit 10 composed of a high-magnification zoom lens and the corresponding built-in flash light emitting device 11, Since it is necessary to store a power supply having a large capacity, a large capacitor, and the like in the camera housing, the size of the camera housing in the thickness direction is inevitably increased to some extent. Focusing on this, taking lens unit 1
0 which is a plane orthogonal to the optical axis of the electronic camera 1

Therefore, it is possible to contribute to reliable connection and improvement of reliability and also to reduction of manufacturing cost.

The main substrate 37 can be formed by a single large-sized substrate having a required substrate area despite being disposed at a position where it does not interfere with the power supply strobe substrate 36. A more efficient circuit design can be performed on the substrate, and a high-magnification zoom lens can be employed without increasing the size of the housing itself.

Further, while the main board 37 is arranged at a position close to the back of the camera housing, the power storage unit 40 and the flash light emitting device 11 inside the gripper 1a are located between the main board and the front of the camera housing.
