Abstract

PROBLEM TO BE SOLVED: To shield mixing and transmission of an undesired signal to a cable of a hinge by allowing the device to have a shield plate having a shield whose one end is fixed to the hinge and covering the cable. SOLUTION: A cable 17 is connected to a terminal 26 of a printed circuit board 25 and inserted between a shield 45 of a shield plate and a support 44. Thus, an undesired signal intruded in the cable 17 is protected by the shield 45 and an undesired signal transmitted from the cable 17 is protected similarly through the shield effect. In the case of turning a PC card section 21 by about 90 deg., the cable 17 is pressed into contact with the tip 45a of the shield 45 and is depressed toward the PC card 21. However, the tip 45a of the shield 45 is smoothly moved without giving damage to the cable 17 by the spring 43 of the shield plate to keep the shield effect of the cable 17.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shield device for an electronic camera with a PC card having a function of connecting to a computer device.

[0002]

2. Description of the Related Art With the recent development of digital technology, electronic cameras have been developed and commercialized as devices for photographing still images.

[0003] In this electronic camera, a captured video signal is stored in a semiconductor memory built in the camera body, and the stored video signal is played back and viewed on a television receiver and a computer device, or an electronic printer device is used. Had a hard copy.

[0004] In particular, when reproduced by a computer device, it is possible to edit a video and generate a new video in combination with a captured video signal and other computer graphic functions, and to organize and store the captured video. As a device, a combination of a computer device and the electronic camera is used.

In order to connect an electronic camera to an electronic device such as a television receiver, an electronic printer, and a computer device, for example, when reproducing on a television receiver, the video reproduced on the television receiver is generally an analog signal. For this reason, it is necessary to convert a digital video signal captured by the electronic camera into an analog video signal and convert the digital video signal into a television signal format. For this purpose, an adapter having a built-in conversion function is used. When the data is reproduced by a computer device, the digital-to-analog signal conversion is not required, and an adapter having a function of simply converting the signal into a signal or data format of the corresponding computer device is required.

1 and FIG. 2 showing an assembled state of the shield plate 41,
The relationship between the shield plate 41 and the cable 17 will be described. The camera body 11 and the PC card unit 21 are both formed to have a small thickness according to the use and use form of the product. Therefore, the camera body 11 and the PC
As the cable 17 for connecting the card unit 21, a cable called a flexible cable in which a plurality of connection lines are provided in parallel on a thin film-shaped insulator is used. One end of the cable 17 is connected and fixed to a terminal 16a of the printed wiring board 16 in the camera body 11 by a connector or soldering. The cable 17
The other is inserted through the space formed between the support part 44 and the shield part 45 of the shield plate 41, and
The PC is inserted through the cable opening 24 of the card unit 21 and
Printed wiring board 2 mounted with electronic circuit means in card section 21
5 is connected and fixed to the terminal section 26 by a connector or soldering. At this time, the shield part 4 of the shield plate 41
The distal end 45 a of the fifth card 5 is configured to be slightly inserted into the PC card unit 21 from the cable opening 24 of the PC card unit 21.

The PC card unit 2 assembled as described above
1, the operation relationship between the hinge portion 31, the shield plate 41, and the cable 17 will be described with reference to FIG. FIG. 3 is the same as FIG.
2 shows a cross-sectional view taken along a cutting line AA of FIG.

FIG. 3A shows a state in which the PC card section 21 is opened 180 degrees from the camera body section 11 (not shown). The cable 17 is connected to the terminal portion 26 of the printed wiring board 25 on which the electronic circuit means is mounted, and is inserted between the shield portion 45 of the shield plate 41 and the support portion 44. Thereby, unnecessary signals entering the cable 17 are protected by the shield part 45, and unnecessary signals transmitted from the cable 17 are similarly protected.

Next, as shown in FIG.
The card section 21 is oriented approximately 90 degrees toward the camera body section 11 (in the figure,
When the hinge 17 is rotated about the second shaft 20 of the hinge portion 31 in the direction of the arrow), the cable 17 is bent. At this time, the cable 17 is connected to the distal end 45a of the shield portion 45.
And is pressed toward the PC card unit 21 side. However, due to the spring portion 43 of the shield plate 41, the distal end 45a of the shield portion 45 moves smoothly without damaging the cable 17, and maintains the shielding effect of the cable 17.

Further, the PC card section 21 is rotated about the second shaft 21 toward the camera body section 11 from the position shown in FIG.
Even if the card portion 21 is closely attached, the shield portion 45 only slightly moves to the camera body portion 11 side, and does not impair the shield effect of the cable 17.

If the shield plate 41 does not exist, the cable 17 inserted into the hinge portion 31 is connected to the camera body 11 and the PC card portion 21.
Due to the opening / closing operation with the hinge part 31, the cable 17 is turned up inside the hinge part 31 and may be damaged inside the hinge part 31.
An effect of pushing the cable 17 into the cable opening 24 of the card portion 21 occurs, and the cable 17 is prevented from being damaged.

[0036]

As described above, according to the present invention, unnecessary signals mixed in or transmitted from the cable are shielded by a slidable shield plate for a cable inserted in a hinge for opening and closing the camera body and the PC card. Of the cable, and also has the effect of preventing breakage of the hinge portion connecting the camera body portion and the PC card portion due to the distortion of the cable caused when the hinge portion is opened and closed.
