C). Conventionally, an FPC 51 as shown in FIG. 5 has been used as an FPC for electrically coupling the CCD imaging block and the camera body. That is, as shown in FIG. 5A, a conventional FPC 51 has a shape in which linear portions 52, 53, and 54 are continuous in a right angle direction. As shown in FIG. 5B, the intermediate linear portion 53 is mounted in such a manner that the intermediate linear portion 53 is rounded in one direction, so that the rounded portion 55 absorbs the twist caused by rotation. [0004] As described above, in the prior art, the F has a shape in which the linear portions 52, 53, 54 are continuous in the perpendicular direction.
Since the PC 51 was used and the intermediate linear portion 53 was formed into a portion 55 that was rounded in one direction, the length of the FPC 51 became longer, which was not suitable for handling a weak current. Further, it has disadvantages in that it is disadvantageous in terms of cost and cannot be made compact. Therefore, an object of the present invention is to shorten the length of the FPC for electrically coupling the imaging block and the camera body so that the FPC is suitable for handling a weak current.
An object of the present invention is to provide an electronic camera device that can also realize cost reduction and downsizing. SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides an image pickup block which is rotatably assembled to a camera body, and which is electrically connected to the camera body by an FPC. In the electronic camera device, one of the camera body and the imaging block, for example, a shaft member fixed to the camera body and serving as a rotation center, and the camera body or the imaging unit penetrating through the inside of the shaft member in the axial direction. The FPC having one of the blocks, for example, a portion connected to the camera body, and a portion extending substantially perpendicularly from this portion and connected to the other of the camera body or the imaging block, for example, an imaging block.
And is characterized by the following. In the FPC, for example, a portion penetrating in the axial direction through a shaft member serving as a rotation center fixed to the camera body is connected to the camera body, and a substantially perpendicular angle is formed from the portion penetrating the shaft member inside. Because the portion extending in the direction is connected to the imaging block, the flexibility of the portion extending substantially perpendicularly from the portion penetrating through the shaft member and connected to the imaging block without bending the FPC in one direction allows the imaging block to be connected to the imaging block. Can absorb torsion caused by rotational movement. Therefore, the FPC can be shortened. An embodiment of an electronic camera apparatus according to the present invention will be described below with reference to FIGS. FIG. 1 shows the appearance of a CCD camera 1 as an example to which the present invention is applied. This CCD camera 1 is divided into a camera body 2 and a CCD image pickup block 21. The camera body 2 and the CCD imaging block 21 are rotatably connected to each other about a shaft member 31 (see FIG. 2) as a center of rotation. In the camera body 2, 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. Further, in the illustrated example, a strap 13 is also provided.
Although not shown, a video output terminal, a digital terminal, an external power terminal, an earphone terminal, and the like 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 of the circuit board 23, and a lens 25 corresponding to the optical unit 24 (see FIG. 4).
Reference). The optical unit 24 includes a CCD (not shown) and a lens system. A connector 26 is provided on the other end 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 that penetrates in the axial direction and is opened in the diameter direction, and protrudes inside through a flange 33 fixed to a side end of the CCD imaging block 21. The FPC 41 that electrically couples the camera body 2 and the CCD imaging block 21 includes a slit 32 of the shaft member 31.
It has a shape that lets through. That is, the FPC 41 is, as shown in FIG.
The forked narrow portions 43, 44 extend from the wide portion 42 in a straight line, and the forked narrow portions 43, 44 are bent in the same direction substantially perpendicular to the wide portion 42 to form a forked width. It has a substantially 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 inserted into the connector 26 and connected, and then bent and overlapped as shown in FIG.
4 is inserted into the camera body 2 through the slit 32 of the shaft member 31. As described above, the forked narrow portions 43 and 44 of the FPC 41 passing through the shaft member 31 are folded in two for compactness, enter the camera body 2 and then bend into 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 configuration, the shaft member 31 is fixed to the camera body 2 side.
No rotation occurs due to the rotational movement of the CD imaging block 21. Therefore, the portions of the FPC 41 (the narrow portions 43 and 44 folded in half) that enter the camera main body 2 from the portion passing through the slit 32 of the shaft member 31 do not generate displacement due to the rotational movement of the CCD imaging block 21. FPC 41 for absorbing displacement due to rotational movement
Is a portion from the entrance portion of the shaft member 31 to the slit 32 to the connector 26, that is, a wide portion 42. Here, it is desired that the connector 26 be located near the edge of the substrate in view of the pattern design of the CCD circuit substrate 23. Therefore, if the entrance 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 slightly slackened to absorb the displacement due to the rotational movement. Next, the rotational movement of the CCD imaging 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 one wide portion 42 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 by 105 ° counterclockwise. As in the case of FIG.
It is curved in the plane direction, but close to tension. FIG. 4C shows a state in which the CCD imaging block 21 is rotated clockwise by 90 °.
The wide portion 42 of p.
It is curved in the plane direction, but 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 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, the flexibility of the FPC 41 in both directions is utilized, and instead of being rounded to the vicinity of the shaft member 31, the entrance to the slit 32 is formed. The displacement is absorbed by only giving the wide portion 42 connecting the connector 26 a little slack. Therefore, the length of the FPC 41 for absorbing the torsion caused by the rotational movement of the CCD imaging block 21 can be shortened. In the embodiment, by appropriately selecting the positions of the shaft member 31 and the connector 26, the conventional structure can be used. The electrical connection between the camera main body 2 and the CCD imaging block 21 by the FPC 41 was achieved with a length of about half of the example. As a result, cost reduction and downsizing were achieved, and the device became suitable for handling a weak current. In the above embodiment, the shaft member is fixed to the camera body, and the FPC portion extending substantially perpendicularly from 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. Conversely, a shaft member is fixed to the CCD image pickup block, and an FPC portion extending substantially perpendicularly from a portion penetrating through the shaft member is connected to the main circuit of the camera body. It may be configured to be connected to a connector on the board. In addition, it goes without saying that specific detailed structures and the like can be appropriately changed. As described above, according to the electronic camera device of the present invention, for example, a portion penetrating in the axial direction through the inside of a shaft member fixed to the camera body and serving as a rotation center is formed in the camera body. An FPC in which a portion extending substantially perpendicularly from a portion penetrating the shaft member is connected to an imaging block.
Accordingly, the FPC can follow and follow the rotational movement of the imaging block without rounding the FPC in one direction, so that the FPC can be shortened, so that it is suitable for handling a weak current, and the cost is reduced. , And can be made compact.
