Abstract

PROBLEM TO BE SOLVED: To suppress the occurrence of abnormal sound by restricting the motion of a cable, by connecting a cover section with the main body section by a flexible cable, and equipping the apparatus with a spring member for biasing the middle section in fixed direction. SOLUTION: The middle section of a front plate 5 is provided with a pair of supporting shafts 5a and 5b, and they are engaged with the coil sections 10a and 10b of a spring member 10, and the ridge section 10c of the spring member 10 is applied to the middle section of a flexible cable 8. The ridge section 10c of the spring member 10 and one surface of the flexible cable 8 are in contact with each other at all times. For the flexible cable 8, the entire motion is restricted, and random motions such as swelling or recessing vertically or reversing from the swelling direction to the recessing direction at rotation of a display part 1 are controlled. As a result of suppressing the random reversing action of the flexible cable 8, the occurrence of abnormal sound can be suppressed.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device having a cover, and more particularly to a cover in which the cover is opened and closed in an electronic device in which the cover and the main body are electrically connected by a flexible cable. The present invention relates to an electronic device having a body.

[0002]

2. Description of the Related Art A conventional electronic device having a lid of this type will be described below with reference to the drawings. FIG. 3 is a partial cross-sectional schematic side view showing an example of an electronic device having a conventional lid. The electronic device has a lid portion (display portion) that opens and closes and a main body portion electrically connected by a flexible cable. This is an example.

In FIG. 3, reference numeral 1 denotes a display unit, 2 denotes a pivot for rotating the display unit 1 in the front-rear direction, 3 denotes an electronic device main body, 4 denotes a wiring board, 5 denotes a front plate, and 6 denotes a wiring board. 7 is an escutcheon, 8 is a flexible cable, and 9 is a flexible cable outlet of the display unit 1.

In the electronic device having such a configuration, even if the display unit 1 is rotated, the display unit 1 and the wiring board 4 are connected by the flexible cable 8, so that the electrical connection state is not affected. Never do.

[0005]

However, in such a configuration, the distance between the flexible cable outlet 9 and the connector 6 changes depending on the rotation angle of the display unit 1, so that the length of the flexible cable 8 is reduced. Is set assuming that the distance is the longest,
When the display unit 1 is rotated, the flexible cable 8 makes a random movement such as bulging in the vertical direction, denting, or reversing from the bulging direction to the concave direction. There is a problem that often.

An object of the present invention is to solve the above-mentioned conventional problems. An electronic device having a cover in which generation of abnormal noise is suppressed by regulating the movement of a flexible cable connecting the cover and the main body. The purpose is to provide equipment.

[0007]

An electronic device having a lid according to the present invention is an electronic device in which a lid portion and a main body portion are electrically connected by a flexible cable, and an intermediate portion of the flexible cable is provided. It is provided with a spring member for urging in a certain direction.

According to the present invention, random movement of the flexible cable during rotation of the lid portion, such as the display portion, is suppressed, so that it is possible to suppress the generation of abnormal noise accompanying the movement.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. It is to be noted that the same reference numerals are used for the same parts as those of the conventional one.

FIG. 1 is an exploded perspective view showing the structure of a main part of an embodiment of an electronic device having a lid according to the present invention, and FIG.
FIG. 2 is a partial cross-sectional schematic side view showing the entire configuration of the electronic device shown in FIG. 1, and is an example of an electronic device in which a lid portion (display portion) that opens and closes and a main body portion are electrically connected by a flexible cable.

In FIGS. 1 and 2, reference numeral 1 denotes a display unit, 2 denotes a support shaft for rotating the display unit 1 in the front-rear direction,
Is an electronic device body, 4 is a wiring board, 5 is a front plate, 6 is a connector for a flexible cable connected to the wiring board 4, 7 is an escutcheon, 8 is a flexible cable,
Reference numeral 9 denotes a flexible cable outlet of the display unit 1. The configuration up to this point is the same as that of the conventional one.

A feature of the present invention resides in that a spring member 10 for urging an intermediate portion of the flexible cable 8 in a predetermined direction is provided, thereby suppressing the random movement of the flexible cable 8. That is, as shown in FIG. 1, a pair of support shafts 5 a and 5 b are provided at an intermediate portion of the front plate 5, and the coil portions 10 a and 10
b is fitted to the pair of support shafts 5a and 5b, and the ridgeline portion 10c of the spring member 10 is applied to the intermediate portion of the flexible cable 8 so that the intermediate portion is positioned at the arrow X in FIG.
The flexible cable 8 is urged in the direction, and the flexible cable 8 is restricted by the entire movement thereof.
Random movement, such as reversing from the expanding direction to the concave direction, is suppressed, and the reversing operation, which is particularly likely to generate abnormal noise, is almost eliminated. As described above, as a result of suppressing the random movement of the flexible cable 8, particularly the reversing operation, it is possible to suppress the occurrence of the abnormal noise.

In this configuration, since the ridge 10c of the spring member 10 and the one surface of the flexible cable 8 are always in contact with each other, the spring member 10 is lubricated with a fluorine coating or the like, and the surface of the flexible cable 8 is By forming a lubricating layer between the spring member 10 and the ridgeline portion 10c of the spring member 10, the frictional resistance between them is reduced, and the display unit 1 performs a smooth turning operation.

As described above, according to the present embodiment, since the intermediate portion of the flexible cable is urged in the predetermined direction by the spring member, the movement of the flexible cable is regulated, and the generation of abnormal noise is effectively prevented. Can be suppressed. Further, by lubricating the spring member, the frictional resistance between the two is reduced, so that the wear on the surface of the flexible cable is reduced, and the display unit can be smoothly rotated.

[0015]

As described above, according to the present invention, since the intermediate portion of the flexible cable is urged in a predetermined direction by the spring member, the movement of the flexible cable is regulated, and the generation of abnormal noise is effectively prevented. An advantageous effect of being able to be suppressed is obtained.
