Description

  The present invention is an image pickup apparatus that enables pan rotation of a camera unit and outputs an image shot by the camera unit to a display device, and is used particularly for transmitting power and signals between the camera unit and a substrate of a fixed part. The present invention relates to a photographing apparatus having a rotating wiring mechanism.

  Conventionally, as described in JP-A No. 2002-344784, the connection between the camera unit and the fixed part substrate is a flexible structure in which a plurality of conductors are arranged in parallel and both surfaces are covered with an insulating tape such as a laminate film. It is configured to be arranged in a spiral around the pan rotation axis. At this time, an outer periphery restricting member for arranging the flex in a spiral shape is formed on the fixed portion.

  This will be specifically described with reference to FIGS.

  FIG. 6 is a state diagram illustrating a state in which the rotating unit 40 is removed from the fixed unit in the conventional imaging apparatus. The camera unit 20 is configured to be rotatable in the directions of arrows A1 and A2 around the tilt unit 50. The tilt unit 50 includes a tilt motor 51, a tilt gear 52, and a tilt motor relay board 53. The pinion gear (not shown) and the tilt gear 52 that are integrally attached to the tilt motor 51 are gear-coupled. By driving, the camera unit 20 is configured to rotate in the directions of arrows A1 and A2. The tilt motor relay substrate 53 is a substrate that is electrically connected to the tilt motor 51 and has a relay function for connecting to the fixed portion with the flexible printed circuit 81. A flex 80 for electrically connecting the camera unit 20 and the fixed portion and a flex 81 for connecting the tilt motor relay board 53 and the fixed portion are wired together and in the vicinity of the pan shaft 41 which is the rotating shaft of the rotating portion. Wired. (FIG. 6) Here, 43 is a pan gear for rotating the rotating part.

Next, a state where the flexible cables 80 and 81 are wired to the fixing portion will be described with reference to FIG. FIG. 7 is a state diagram illustrating a state in which flexible wiring is provided in a conventional imaging device. The rotating unit 40 is mounted with a camera unit, and is attached to the fixed unit by fitting the pan shaft 41 and the bearing unit 31 of the fixed unit 20. At this time, the pan gear 43 of the rotating unit 40 is gear-coupled to a pinion gear (not shown) of the pan motor 42, and the pan unit 40 rotates in the B1 or B2 direction when the pan motor 42 rotates. Further, the above-described flexes 80 and 81 are wired in a spiral 82 within the flexi 70 provided in the fixed portion 30. The reason why the flexible wires are wired in this manner is to provide an extra length on the wiring when the rotating portion rotates in the B1 or B2 direction.

  In the case of the above configuration, static electricity may be generated in the flex when the flex is slid in the flex case due to the rotation of the rotating portion. For this reason, the flexible wiring may cause unexpected troubles such as electrostatic breakdown. Furthermore, in order to obtain slidability, the flexible case is often made of a plastic material such as POM, which makes it difficult to form a conduction path to the ground, and the potential of the flexible case in the flexible case becomes unstable. There are many.

The present invention has been made in view of such technical drawbacks.
A rotating unit including a camera unit; drive means for rotating the rotating unit; a fixing unit electrically connected to the camera unit by a flexible cable; and an outer periphery of the cable being restricted; The flexible case has a slidable and electrically conductive sheet inside.

In addition, the sheet is at least
The sleeve is configured to be in contact with and conductive with any one of a sleeve that supports the shaft of the rotating portion, a flexible case, or a base of the fixed portion.

  According to the present invention, since the sheet having slidability and conductivity is disposed in the flexible case, good flexible sliding is realized, and furthermore, static electricity generated by the flexible sliding is easily removed from the base. You will be able to lead to the ground.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The configuration of the tilt unit 50 is configured such that the tilt gear 52 that is gear-coupled with the drive of the tilt motor 51 rotates, and the camera unit 20 is rotatable about the tilt unit 50 in the directions of arrows A1 and A2.

  FIG. 2 is a state diagram in which the flexible case of the first embodiment is about to be attached to the rotating part. The fitting portion 60b of the flexible case 60 of the present invention and the flexible case fitting portion 44 of the rotating portion are configured to be temporarily fixed to the rotating portion 40 by light press-fitting, and the flexible case 60 is moved in the direction of arrow C. , Fixed to the rotating unit 40.

  FIG. 3 is a state diagram in which a flat cable is wired to a flexible case in which the flexible case of the first embodiment is mounted on a pan rotating part. In a state where the flexible case 60 is temporarily fixed to the rotating unit 40, the flexible cables 80 and 81 are spirally wired (82) as shown in FIG. At this time, since the helical terminal portion is temporarily fixed to the terminal fixing slit 60e of the flexible case 60, the wiring does not move. In the present embodiment, an example in which only the outer periphery is restricted and the flex is stored has been shown.Of course, the lower end surface of the flex is also regulated to form a storage space so that the inner circumference of the flex does not hang downward. It doesn't matter.

  FIG. 4 is a state diagram showing a state in which the pan rotating part of the first embodiment is mounted on the fixed part. The rotating unit 40 is attached to the fixing unit 30 in a state where the wiring is temporarily fixed and the flexible wiring is finished. As in the case described with reference to FIG. 6, at this time, the rotating portion 40 is attached by fitting the pan shaft 41 and the bearing portion 31 of the fixed portion 20. At this time, the pan gear 43 of the rotation unit 40 is connected to a pinion gear (not shown) of the pan motor 42, and the rotation of the pan motor 42 allows the rotation unit 40 to rotate in the B1 or B2 direction. .

  FIG. 5 is a cross-sectional view of the flexible case of the present invention attached to the fixed portion.
