Abstract

PURPOSE:To reduce a cable load to be generated during operation of a movable unit by forming a cable into a specific shape in the cable for electrically connecting the movable unit capable of operation in two directions to a fixed unit. CONSTITUTION:A photographing unit 1 capable of a panning operation in the horizontal direction and a tilt operation in the vertical direction is electrically connected to a connector 7 of an image processing base board via a cable 4. The cable 4 comprises a first arm 401 for reducing a cable load during the panning operation and a second arm 402 for reducing a load during the tilt operation. The first arm 401 is formed into an S shape so as to be deformed according to the initial state during the panning operation, thus reducing a variation in the bending direction of the cable 4. In the same manner during the tilt operation, a moderately curved surface formed on the second arm 402 absorbs thereon a load generated during the tilt operation, thereby reducing deformation caused by the operation.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to cables, and more particularly to FPC cables used for moving parts that are movable in at least two different directions.

[0002]

2. Description of the Related Art Conventionally, FPC cables have been widely used for saving space for electricity and precision equipment.

[0003]

However, the present F
When a PC cable is used for a movable part, it can be applied only in one direction, and therefore it has not been introduced into a movable part that can operate in two or more directions. Furthermore, FPC cables used for transmitting video signals are shielded to prevent noise, and are commonly used.
The rigidity was higher than that of the PC cable, and it was not introduced into the moving part due to problems such as load. Also, FP
When the C cable is used for the movable part, there are problems such as durability.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention provides an FPC.
By forming a shape on the cable that reduces the generation of a cable load due to the operation, it is possible to support the operation in a plurality of directions, and further, the factory is made to have durability.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the image input device shown in FIG. In FIG. 1, reference numeral 1 denotes a photographing unit for inputting an image, and the photographing unit 1 is fixed to a pan head unit 2 capable of pan (X direction in the drawing) and tilt (Y direction in the drawing) operations.

The pan operation is a horizontal operation, and the tilt operation is a vertical operation. The pan and tilt operations of the platform unit 2 are supported on the base 5 so that they can be performed by a driving means (not shown).

Reference numeral 3 denotes an image processing board for processing an image signal picked up by the shooting unit 1. The image processing board 3 is fixed on a base 5. Reference numeral 4 denotes an FPC cable that electrically connects the image pickup unit 1 and the image processing board 3, and the cable 4 is shielded to prevent noise.

The cable 4 has a first arm portion 401 for reducing the cable load during the pan operation and a second arm portion 402 for reducing the load during the tilt operation.
Is formed, and the first arm portion and the second arm portion are formed so as to be in directions corresponding to the operation direction.

Reference numerals 6 and 7 denote connectors for electrically connecting the cable 4 to the photographing unit 1 and the image processing board 3, and the connectors 6 and 7 correspond to the pan and tilt operations of the camera platform unit 2. , As shown in FIG.

Referring to FIG. 2, the change of the cable 4 during the pan operation will be described. First arm portion 401 of cable 4
Is formed into an S shape, and when the pan head unit 2 performs a pan operation, the cable 4 is deformed while learning the initial state. Therefore, the change in the bending direction of the cable 4 can be reduced, the generated load can be reduced, and the durability can be improved.

Similarly, during the tilting operation, as shown in FIG. 3, the gentle curved surface portion formed on the second arm portion 402 absorbs the load generated by the tilting operation on the curved surface. , Less deformation due to movement,
The generated load can be reduced.

As described above, when the cable 4 is changed in the pan and tilt operations, the first
Since the arm portions 401 and the second arm portions 402 correspond to each other, the generated load is reduced. Furthermore, because each arm has a shape that is less deformed by the movement of the movable part,
The load on the cable can be reduced and the durability can be improved.

(Other Embodiments) A second embodiment of the present invention will be described with reference to FIG. Reference numeral 8 denotes an FPC cable, and the cable 8 has a slit formed in at least a part thereof. The cable 8 has lower rigidity as compared with the FPC cable in which the slit is not formed by the slit, the cable load generated by the operation of the movable portion is reduced, and the flexibility of deformation is increased.

When the pan / tilt head unit 2 performs a pan or tilt operation, the cable 8 is accordingly deformed while partially overlapping each other as shown in FIG. The first embodiment
It is also effective to combine with the embodiment of.

[0015]

As described above, the first direction and the first direction
In a device having a movable part operable in at least a second direction different from the above direction and a fixed part supporting the movable part, an FPC for electrically connecting the fixed part and the movable part
By changing the shape of the cable so that the deformation of the cable caused by the operation of the movable part is suppressed, the cable load generated during the operation of the movable part is reduced and it is possible to introduce the cable into the movable part.
