Abstract

PURPOSE:To completely shut off the effect of external noise or reversely noise leaking out from a camera by applying conductivity treatment to a translucent member, which constitutes a translucent part, and placing it in a shield structure. CONSTITUTION:For an eyepiece 3, the surface is coated with transparent conductive film 3A. An eyepiece presser 4 made of conductor electrically connects the conductive film 3A overlaid on the surface of the eyepiece 3 with the conductive part of a body, a flexible board 6 for shielding, and others, and gives specified potential to the conductive film 3A. By covering the circumference, other than light taking-in part, of a silicon photocell module 2 with the flexible board 6 for shielding, excluding the eyepiece 3, and covering the surface of the eyepiece 3 with the conductive film 3A, the SPC module 2 is shielded, and the effect of noise irradiated from the body of a photographer is shut off. Moreover, by connecting the flexible board 6 for shielding and the conductive film 3A to the conductive part of the camera body thereby giving fixed voltage, the shielding capacity can be elevated further.

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to electrical shielding for devices containing electrical devices sensitive to external noise, such as automated cameras. (Prior art) The photometric signal obtained from the silicon photometric cell (hereinafter referred to as SPC), which is the light receiving element of the photometric circuit of the camera, is the most important signal in the camera, and because it is a weak current, The signal is susceptible to noise. Therefore, it is necessary to use a shield to protect the SPC from noise. On the other hand, as microcontrollers for controlling cameras become faster and flashes become built-in, the circuit inside the camera The generation of noise from the camera is also a problem.In other words, this noise may have a negative effect on electrical products around the camera and cards that use magnetism, and may also violate radio regulations. , a shield is also required to block noise radiation from the camera.As shown in FIG. By vapor depositing or plating and shielding the external parts, SPC
Module 2 was shielded. However, since the shield member is opaque, it cannot cover the transparent parts of the camera, such as the eyepiece and the light receiving window 5 of the SPC module 2, so the shielding effect on the SPC module 2 is reduced. The problem was that it was weak. In particular, the human body acts as an antenna, and various radio waves are emitted through the body.
It has become clear that noise emitted from the photographer's body can enter the camera through the eyepiece and cause trouble. However, in the past, there was no idea of shielding the transparent material, and the eyepiece was not shielded, so it was not possible to remove the noise that entered from the eyepiece. Also,
Recent cameras have become more electronic, and electronic circuits are now built into the lens barrel. Therefore, the camera lens must also be considered as a point where external noise enters or where radiated noise leaks. Furthermore, many recent cameras use liquid crystal as a display device, and as shown in FIG. , because it does not have a shield structure,
It was not possible to prevent noise from entering the camera from the LCD display, or conversely from noise leaking from the camera. In particular, there is an IC for driving the liquid crystal near the liquid crystal display device.
17 is often provided, and there is a problem in that noise leaks from this to the outside of the camera. Furthermore, although it was known to shield opaque parts of devices other than cameras, shielding of transparent parts had not been done. Thus, in the past, there was no general idea of shielding electrical equipment up to the transparent parts. (Problem H to be solved by the invention) Since the noise that enters through the transparent part and the noise that leaks from the transparent part cannot be ignored, the present invention makes it possible to completely shield the entire system such as a camera from the outside. The purpose is to

(Means for solving the problem) In a device having a light-transmitting part, the surface of the transparent member of the light-transmitting part is coated with a transparent conductive film, or the transparent member is mixed with conductive particles. Electrical treatment was applied. (Function) By coating a transparent body with a transparent conductive film such as IT○ film (indium oxide, tin oxide M) or NESA film (tin oxide film), or by mixing a conductive substance into the transparent body, Forming a transparent conductive film on the surface of a transparent body is a conventionally known method for forming electrodes on a transparent body.In the present invention, shielding is possible by such conductive treatment. By focusing on this and shielding the transparent parts, which had been ignored in the past, it is now possible to prevent noise from entering and leaking through the transparent parts, which could not be prevented in the past. Furthermore, by shielding components other than transparent components using conductive flexible substrates or shielded components as in the past, it is possible to create a shield structure around the entire camera.
<<Example>> Figure 1 shows an example of the present invention in which shielding measures are taken against the SPC of a photometric device placed in the optical path of a camera's single-lens reflex finder. In FIG. 1, 1 is a pentaprism, and 2 is an SPC module which is a light receiving element of a photometry circuit that measures light from the pentaprism 1. 3 is an eyepiece with a transparent conductive film on its surface (e.g. IT○ film or Nesa I film).

As shown in FIG. 2, the surrounding area of the SPC module 2 other than the light intake part is covered with a flexible shielding substrate 6 except for the eyepiece 3, and the surface of the eyepiece 3 is covered with a conductive M3.
By covering it with A, the SPC module 2 is shielded and the influence of noise emitted from the photographer's body is cut. Furthermore, the shielding ability can be further enhanced by connecting the shielding flexible substrate 6 and the conductive film 3A to the conductive part of the camera body and applying a constant potential. Figure 3 shows another example in which shielding measures were taken against the above-mentioned SPC. In Fig. 1, the optical system of the SPC module 2 is shielded by coating the surface of the eyepiece 3 with transparent conductive M3A, whereas in Fig. 3, the surface of the eyepiece lens 3 is coated with transparent conductive M3A, while in Fig. A conductive film 1A is coated on a part of the surface of the SPC, and a conductive film 5A is provided on the SPC light receiving window 5 in the eyepiece. This is done using a flexible board 6. As a result, the SPC module 2 is completely shielded as in the embodiment shown in FIG.
It is possible to cut out the effects of noise emitted from the photographer's body. In this embodiment, since the light receiving window 5 of the SPC is shielded, it is completely shielded from noise that may enter from the eyepiece lens as well as from the photographing lens. However, by providing the conductive film 5A on the SPC light receiving window 5, the amount of light incident on the SPC module 2 may be reduced. By correcting the photometric value, accurate photometric values with high noise resistance can be obtained. FIG. 4 shows an embodiment of the present invention in which shielding measures are taken for the liquid crystal display section 10. Reference numeral 11 denotes a liquid crystal holder, which is placed on a printed wiring board 16 via a liquid crystal driving circuit including a liquid crystal driving IC 17. The liquid crystal holder 11 has an anisotropic conductive rubber 15 connected to the liquid crystal drive circuit.
The liquid crystal display section 10 is held through the. Here, the anisotropic conductive rubber 15 is formed by alternately laminating conductive parts having elasticity and insulating parts having elasticity, and is a member having conductivity in only one direction. The stacking pitch between the conductive part and the insulating part is less than 172 times the pitch of the electrodes to which the anisotropic conductive rubber 15 is to be connected. A transparent member 12 coated with a conductive film is installed on the liquid crystal display section 10. The conductive film is also formed of an IT○ film or a NESA film. In addition, if the display on the liquid crystal display section 10 is sufficiently transparent to be visible from above,
A transparent plastic plate mixed with charged particles such as nickel, iron, or solder balls can also be used as the transparent member 12. A liquid crystal holding plate 13 is installed on the transparent member 12, and the liquid crystal holding plate 13 and the printed wiring board 16 are fixed with screws 14. As a result, the transparent member 12 and the liquid crystal display section 10 are placed between the liquid crystal holding plate 13 and the printed wiring board 16.
, the anisotropic conductive rubber 15 and the liquid crystal holder 11 are held, and the electrodes on the liquid crystal display section 10 and the anisotropic conductive rubber 15 are held together.
, the anisotropic conductive rubber 15 is brought into pressure contact with the electrode on the liquid crystal drive circuit. Here, by connecting the liquid crystal holding plate 13 to a part having a predetermined potential such as GND of the camera circuit, the chassis, etc., the conductive film on the transparent member 12 or the transparent member itself can be maintained at a predetermined potential. , it becomes a shield structure. The above liquid crystal drive circuit includes an oscillator, which is a source of noise. Conversely, this oscillator is also easily affected by external noise. However, since the transparent member 12 acts as a shield, such noise is prevented. 1. If the area around the liquid crystal display section is placed as a conventional shield, it will become a closed shield structure, creating an almost complete seal. can be performed. FIG. 5 is a diagram schematically showing an example in which the present invention is applied to a photographing lens optical system of a single-lens reflex camera. In FIG. 5, 20 is a lens barrel, and 21 is a photographic lens whose outer surface is coated with a transparent conductive film 21A. 22 is a conductive part provided inside the lens barrel 20, and the conductive film 21
It is electrically connected to A. 23 is an in-lens electronic circuit provided inside the conductive tube 22, and 24 is connected to the camera body through a contact electrode provided at the inner end of the conductive tube 22 on the side of the camera body. 25 is a lens side seat plate that comes into contact with the camera side seat plate when the lens is attached to the camera body. When attached to the camera body, the contact electrode 24 is connected to the contact electrode on the camera body side, so that the conductive cylinder portion 22 and the conductive film 21A are equal to a predetermined potential such as GND inside the camera body. In the embodiment shown in FIG. 5, due to the shield structure consisting of the conductive film 21A coating the lens 21 and the conductive cylinder portion 22, the shield is open only in the direction in which the lens is mounted. A camera equipped with this lens system is
If the shield structure or conventional shield ellipse as shown in Figures 1 and 4 is used to shield parts other than the lens mount, the shield ellipse becomes completely closed when the lens is attached. , the entire camera system can be shielded. (Effects of the Invention) According to the present invention, by shielding the light-transmitting part with a transparent member such as a transparent conductive film, it becomes possible to completely shield the part that requires shielding, and the radiation emitted from the photographer. We were able to completely cut out the effects of external noise such as noise from the camera, and conversely, noise leaking from the camera, resulting in extremely high noise resistance.
