Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a camera having a structure that prevents internal electronic components from being destroyed by static electricity.
[0002]
[Prior art]
In order to prevent destruction of electronic components inside the camera due to charging of the human body or the camera body, various cameras with anti-static measures have been proposed.
[0003]
For example, Japanese Utility Model Laid-Open No. 3-108232 discloses a camera in which a conductive member is provided outside the camera body, and the conductive member is electrically connected to the negative electrode terminal of the battery through the connecting member.
[0004]
In JP-A-61-133929, a conductive member is attached to the inside of a non-conductive battery lid that closes the battery storage chamber formed at the bottom adjacent to the conductive camera body, There has been disclosed a camera provided with a connecting member for electrically connecting a conductive member and a camera body with a battery cover closed.
[0005]
In addition, as shown in FIG. 3, the applicant of the present application previously has a conductive exterior member 102 covering the camera body (not shown) and a negative terminal of a battery (not shown) that supplies power to the camera body. The contacted battery contact piece (not shown) was electrically connected via a printed board 103 having a conductive screw 104 for fixing the exterior member 102 to the camera body and a connection portion 103a with the battery contact piece. Camera 101 was proposed.
[0006]
[Problems to be solved by the invention]
In each of the prior art examples described above, parts such as a connecting member and a printed circuit board are newly added to electrically connect the two members to be conducted, and this is a major obstacle to downsizing. There is a problem of becoming.
[0007]
Further, as the number of parts for electrically connecting two members to be conducted increases, the reliability of conduction between the two members decreases due to poor contact between these parts. Yes.
[0008]
The present invention has been made to solve the above-described problems, and has an object to have a structure that prevents internal electronic components from being destroyed by static electricity, and to be compact and improve reliability. It is to provide a camera that is intended.
[0009]
[Means for Solving the Problems]
In order to achieve the above-described object, the invention of claim 1 is directed to a camera body supplied with power by a battery to be loaded , and a conductive battery in contact with a terminal of the battery that supplies power to the camera body. A camera comprising: a contact piece; a conductive exterior member that covers the camera body; and a conductive fixing member that fixes the exterior member to the camera body. The piece is configured to conduct through the fixing member.
[0010]
The invention of claim 2 is characterized in that, in the invention of claim 1, the fixing member fixes the battery contact piece on the negative electrode side to the camera body.
[0011]
The invention of claim 3 is characterized in that, in the invention of claim 1 or claim 2, the fixing member is a screw.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a partially cutaway front view of an embodiment of the present invention, and FIG. 2 is a side sectional view of FIG.
[0013]
As shown in the figure, a camera 1 according to this embodiment includes a camera body 2 and an electric circuit (not shown) housed in a battery housing chamber 3 formed at the bottom of the camera body 2 and built in the camera body 2. A battery 4 for supplying power to the battery, battery contact pieces 5 and 6 in contact with the positive terminal 4a and the negative terminal 4b of the battery 4 stored in the battery storage chamber 3, an exterior member 7 for covering the camera body 2, A plurality of screws 8 for fixing the exterior member 7 to the camera body 2 are provided.
[0014]
The camera body 2 includes a frame 9 that supports components (not shown) such as an electric circuit. The frame 9 is provided with an attachment hole 9a for fixing the exterior member 7, and the attachment hole 9a On the inner peripheral surface, a screw thread that is screwed into the shaft portion of the screw 8 is formed.
[0015]
The battery contact pieces 5 and 6 are formed of a conductive metal, and the battery contact piece 6 on the negative electrode side has a screw hole 6a into which the shaft portion of the screw 8 is screwed. The double-sided adhesive tape 10 is temporarily fixed to the frame 9 so as to be aligned with one of the mounting holes 9a provided in the frame 9. On the other hand, the battery contact piece 5 on the positive electrode side is fixed to the frame 9 with a wire such as a wire.
[0016]
The exterior member 7 is formed of a conductive metal and has a plurality of through holes 7a through which the shaft portion of the screw 8 passes. The screw 8 is formed of a conductive metal. When the exterior member 7 is fixed to the frame 9 of the camera body 2 with screws 8, one screw 8 passes through the screw hole 6 a provided in the battery contact piece 6, and the battery contact piece 6 is fixed to the frame 9. ing. As a result, the exterior member 7 and the battery contact piece 6 are brought into conduction through the screw 8, so that static electricity does not flow into the camera body 2 even when a charged object such as a human body touches the exterior member 7. There is no danger of electronic components being destroyed by static electricity.
[0017]
In the present invention, since no new parts are added to electrically connect the exterior member 7 and the battery contact piece 6, it is advantageous in terms of space and can be made compact. In addition, since the number of parts that electrically connect the exterior member 7 and the battery contact piece 6 is minimal, poor conduction is unlikely to occur.
[0018]
In the present embodiment, the screw 8 that electrically connects the exterior member 7 and the battery contact piece 6 fixes the battery contact piece 6 to the camera body 2. 6 is not required, and the structure of the camera body 2 is simple. In addition, the battery contact piece 6 does not need to be firmly fixed to the camera body 2 and only needs to be temporarily fixed. Good workability. The battery contact piece 6 may be temporarily fixed to the exterior member 7 side.
[0019]
【The invention's effect】
As described above, according to the present invention, the exterior member and the battery on the negative electrode side are electrically connected to each other via the fixing member that fixes the exterior member to the camera body. Since it is not necessary to add a new part for electrically connecting the contact pieces, it is possible to reduce the size. In addition, since the number of parts that electrically connect the exterior member and the battery contact piece on the negative electrode side is the smallest, poor conduction is unlikely to occur and the reliability is high.
[0020]
According to the camera of claim 2, since the fixing member is configured to fix the battery contact piece on the negative electrode side to the camera body, it is necessary to provide a portion for fixing the battery contact piece on the negative electrode side on the camera body side. In addition, the camera body is simplified, and the battery contact piece on the negative electrode side does not need to be firmly fixed to the camera body, so that the workability during manufacturing is improved.
