DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of an electronic camera device according to the present invention will be described below with reference to FIGS.

First, FIG. 1 shows the appearance of a CCD camera 1 as an example to which the present invention is applied. The CCD camera 1 is divided into a camera body 2 and a CCD image pickup block 21. The camera body 2 and the CCD image pickup block 21 are rotatably connected with a shaft member 31 (see FIG. 2) as a rotation center.

The camera body 2 includes, for example, a finder 3, a function changeover switch 4, a power switch 5,
Self-timer key 6, zoom key 7, display key 8, mode key 9, minus key 10, plus key 1
1, a shutter button 12 and the like are provided. Furthermore, in the illustrated example, a strap 13 is also provided, and in addition,
Although not shown, a video output terminal, a digital terminal, an external power terminal, an earphone terminal, etc. are provided. Also, CC
The D imaging block 21 includes a lens changeover switch 22.

As shown in FIG. 2, a CCD circuit board 23 is provided in the CCD image pickup block 21.
An optical unit 24 is mounted on one end side of the circuit board 23, and a lens 25 (FIG.
(See) is provided. The optical unit 24 is composed of a CCD and a lens system (not shown). A connector 26 is provided on the other end side of the CCD circuit board 23.

A shaft member 31 is fixed to the side end of the camera body 2 in a protruding state. This shaft member 31
Has a slit 32 penetrating in the axial direction and opened in the diameter direction, and penetrates a flange 33 fixed to a side end portion of the CCD imaging block 21 to project inward. The FPC 41 that electrically connects the camera body 2 and the CCD imaging block 21 includes a slit 32 of the shaft member 31.
It is shaped to pass through.

That is, the FPC 41, as shown in FIG.
It is a linear shape in which the forked narrow portions 43 and 44 extend from the wide portion 42, and the forked narrow portions 43 and 44 are bent in the same direction substantially at right angles to the wide portion 42 to form a forked width. It has a general L-shape in which the narrow portions 43 and 44 are overlapped.

The terminal portion 4 of the wide portion 42 of the FPC 41
As shown in FIG. 2, the narrow portions 43 and 4 are formed by inserting the connector 2a into the connector 26 and coupling the connector 2a, and then bending and overlapping the connector 2a.
4 is inserted into the camera body 2 through the slit 32 of the shaft member 31. In this way, the forked narrow portions 43 and 44 of the FPC 41 passing through the shaft member 31 are folded in two for compactness, and after entering the camera body 2, are folded in two for each connector not shown. Being
The terminal portions 43a and 44a are respectively inserted and connected to connectors of a main circuit board (not shown) in the camera body 2.

According to the CCD camera 1 having the above structure, the shaft member 31 is fixed to the camera body 2 side, and C
No rotation occurs due to the rotational movement of the CD imaging block 21. Therefore, the portions of the FPC 41 (the narrow width portions 43 and 44 that are folded in half) that enter the camera body 2 from the portion that passes through the slit 32 of the shaft member 31 are not displaced by the rotational movement of the CCD imaging block 21.

FPC41 that absorbs displacement due to rotational movement
The portion is a portion from the entrance portion of the shaft member 31 to the slit 32 to the connector 26, that is, the wide portion 42. Here, it is desirable that the connector 26 is located near the end of the board in view of the pattern design of the CCD circuit board 23. Therefore, if the inlet of the shaft member 31 to the slit 32 and the connector 26 are connected by a straight line, a certain length is inevitably obtained. In the present invention, this portion, that is, the wide portion 42 is provided with a slight slack to absorb the displacement due to the rotational movement.

Next, the rotational movement of the CCD image pickup block 21 and the deformation of the FPC 41 according to the present invention will be described step by step with reference to FIGS. First, FIG. 4A shows a normal state in which the CCD image pickup block 21 is not rotated with respect to the camera body 2.
The wide portion 42 of No. 1 is gently curved in the p-plane (pattern surface) direction.

FIG. 4B shows a state in which the CCD image pickup block 21 is rotated counterclockwise by 105 °. As in the case of FIG. 4A, the wide portion 42 of the FPC 41 has a width p.
Curved in the plane, but close to tension.

FIG. 4 (c) shows a state in which the CCD image pickup block 21 is rotated clockwise by 90 °.
The wide portion 42 of 1 is p near the connector 26.
Although it is curved in the surface direction, it is not curved near the shaft member 31.

FIG. 4D shows a state in which the CCD image pickup block 21 is rotated clockwise by 195 °.
The wide portion 42 of 41 is curved in the p-plane direction near the connector 26, but is conversely curved in the b-plane (back surface) direction near the shaft member 31.

As described above, in response to the rotational movement of the CCD imaging block 21, by utilizing the flexibility of the FPC 41 in both surface directions, the FPC 41 is not rounded in the vicinity of the shaft member 31 but is provided at the entrance to the slit 32 thereof. The wide portion 42 connecting to the connector 26 is provided with a slight slack to absorb the displacement.

Therefore, the length of the FPC 41 for absorbing the twist due to the rotational movement of the CCD image pickup block 21 can be shortened, and in the embodiment, by appropriately selecting the positions of the shaft member 31 and the connector 26, the conventional structure can be realized. With about half the length of the example, the electrical connection between the camera body 2 and the CCD imaging block 21 by the FPC 41 could be realized. As a result, the cost can be reduced and the size can be reduced, which is suitable for handling a weak current.

In the above embodiments, the shaft member is fixed to the camera body, and the FPC portion extending in a direction substantially perpendicular to the portion penetrating the shaft member is connected to the connector of the CCD circuit board. However, the present invention is not limited to this, and conversely, the shaft member is fixed to the CCD imaging block, and the FPC portion extending substantially at a right angle from the portion penetrating the inside of the shaft member is provided in the main circuit of the camera body. It may be configured to be coupled to a connector on the board. In addition, it is needless to say that the specific detailed structure and the like can be appropriately changed.

[0024]

As described above, according to the electronic camera device of the present invention, for example, a portion axially penetrating the inside of the shaft member fixed to the camera body and serving as the rotation center is connected to the camera body. , An FPC in which a portion extending substantially at right angles from a portion penetrating the inside of the shaft member is connected to an imaging block
By this, since it is possible to follow the rotational movement of the imaging block without rounding the FPC in one direction, it is possible to shorten the FPC, which makes it suitable for handling a weak current, and also reduce the cost. , And can be made compact.
