Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a processing structure for wiring housed inside an optical device such as a camera.

[Conventional technology]

In recent years, as devices such as cameras have become more electronic, the number of wires housed inside them has also continued to increase.

Conventionally, these wirings were constructed by bundling multiple coated conductors together or arranging them as a flexible board along the inner and outer walls of the frame, and fixing them by attaching them to the frame at key points or gripping them with fixtures. It was getting worse.

[Problem that the invention attempts to solve]

However, in the case of such conventional optical equipment, the location where the wiring is fixed is often in an extremely narrow space, which makes processing difficult, and the fixed wiring may become loose due to vibration, etc.
There was a risk of accidents such as wire breakage and short circuits due to sliding contact with fixed members and movable members.

In addition, in order to solve these drawbacks, if the frame that fixes the flexible board is a molded product of synthetic resin, the flexible board that is wired during the molding process is embedded in the frame and molded integrally. has also been proposed, but there was a problem in that if the wiring was changed due to improvements in electrical parts or circuits, all the molded frames could no longer be used.

The purpose of this invention is to provide an optical device that can solve these conventional problems.

[Means for solving problems]

Therefore, the optical device according to this invention consists of a frame of an optical device such as a camera that has a partially opened elongated hole, and an anti-reflection device that has an adhesive surface coated with adhesive attached to the inner surface of the frame. It consists of non-reflective paper and wiring that is adhered to the adhesive surface of the non-reflective paper exposed in the elongated hole and housed within the elongated hole.

[Effect]

With the above configuration, the wires such as coated conductors and flexible substrates housed in the long holes of the frame are pasted on the adhesive surface of the non-reflective paper exposed at the bottom of the long holes, and are separately coated with adhesive. It can be fixed immovably without using a fixture.

〔Example〕

Embodiments of this invention will be described below with reference to the accompanying drawings.

Figure 1 shows an example of this invention.
On the inner surface of the frame body 1 through which light rays pass, a non-reflective paper 2 such as flocked paper with an adhesive surface coated with adhesive on the back side is pasted, and a part of the frame body 1 is opened. The adhesive surface 5 of the non-reflective paper 2 is exposed at the bottom of the elongated hole 3.

Therefore, the wiring 4 is inserted into the long hole 3 except for both terminals.
When stored inside, the storage portion 6 is firmly adhered to the back surface of the non-reflective paper 2 with the adhesive surface 5, and is completely embedded in the thickness of the frame 1, so there is no risk of sliding contact with other members.

Note that 7 in FIG. 1 is a switch connected to one terminal portion of the wiring 4.

Next, FIG. 2 shows another embodiment of this invention, in which a non-reflective paper 9 having an adhesive surface on the back side is pasted on the inner circumferential surface of a lens frame 8 which is a frame body for housing the lens. The adhesive surface of the non-reflective paper 9 is exposed at the bottom of the elongated hole 11 opened in the side surface of the lens frame 8.

Further, a terminal plate 13 is fixedly attached to the flange portion of the lens frame 8 to connect one end of a flexible board 12 having printed wiring, and the other end 10 of the flexible board 12 is connected to a conductor outside the elongated hole 11. and connected to respective predetermined circuits.

In this way, the flexible substrate 12 housed in the elongated hole 11 is firmly adhered to the exposed adhesive surface of the non-reflective paper 9 and is completely embedded in the thickness of the lens barrel 8.

In addition to flocked paper, the non-reflective paper used in the above embodiments may also be a paper with many crepe-like or tortoise-like irregularities on the surface, and its material is not limited to paper, but may include synthetic resins and metals. There is no problem with sheets, etc.

[Effect of idea]

As mentioned above, the optical device according to this invention has a long hole in a part of the frame with non-reflective paper pasted on the inner surface, and the wiring is housed in this long hole and attached to the adhesive surface on the back side of the non-reflective paper. Since it is attached, there is no need for separate adhesives or fixtures, and the workability of wiring is greatly improved.

In addition, the fixed wiring can be completely buried in the long hole of the frame, so it can be easily stored in a narrow space, and the fixed wiring can be installed in close proximity to other parts. There is no risk of accidents such as wire breakage or short circuits due to sliding contact with the wire.
