BACKGROUND OF THE INVENTION
The present invention relates to a sliding contact surface protection structure for an imaging device that can protect the sliding contact surface of an imaging device having a casing that is slidably installed to extend the durability of use of the imaging device.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, in a photographing device such as a video camera, a housing such as a finder is slidably installed so as to perform a rotation tilt (up / down) operation or a slide (front / rear) operation. The exterior of such a photographic device is painted for beauty. On the other hand, the surface on which the casing and the photographing device are in sliding contact is often not painted. For example, the surface where the finder and the liquid crystal panel installed in the video camera are in sliding contact is not painted. This is because when the casing and the photographing device are in sliding contact, the sliding contact surfaces rub against each other, so that the coating is not peeled off and the appearance is not damaged.
[0003]
Even when the sliding contact surfaces are not coated, it is necessary to prevent the entire sliding surfaces from being scratched by the sliding contact surfaces. For this reason, a protruding portion or a rail-like convex portion (hereinafter referred to as a protruding portion or the like) is provided on the sliding contact surface of the photographing apparatus. The convex portion is formed in a rail shape in accordance with the locus of the casing that slides. The projections provided on the sliding contact surface of the photographing apparatus and the sliding contact surface of the housing are in sliding contact. In this way, the entire sliding surface of each other is prevented from sliding and the entire surface is prevented from being scratched.
[0004]
On the other hand, recently, metal housings have been used for photographing equipment. In this case, it is necessary to coat the sliding surface. Even when a plastic housing is used, the sliding contact surface is often painted to enhance the texture.
[0005]
[Problems to be solved by the invention]
If the sliding contact surface is also coated when the projections are provided, the sliding operation is repeated, so that the projections and the sliding contact surface of the housing are positively Make sliding contact. As a result, the coating of the protrusions and the like is peeled off. Furthermore, even on the sliding contact surface of the casing, the paint is peeled off along the sliding trajectory of the casing, or scratches are attached, resulting in a loss of aesthetics. Therefore, when painting on the sliding contact surface, it is difficult to provide the protrusions and the like because of the need to maintain aesthetic appearance.
[0006]
However, if the projections are not provided, the entire sliding contact surfaces are scratched by sliding of the casing. Furthermore, the coating film peels over a wide range of the sliding contact surface, and the aesthetic appearance is impaired. Moreover, in a metal housing, if the paint film is peeled off, it causes rust.
[0007]
The present invention has been made in consideration of the above-described circumstances, and an object of the present invention is to protect the sliding contact surface of a photographing apparatus having a casing that is slidably installed so that the durability of the photographing apparatus can be used. An object of the present invention is to provide a slidable contact surface protection structure for an imaging device that can extend the performance.
[0008]
[Means for Solving the Problems]
In order to solve the above-described problem, the sliding contact surface protecting structure for a photographing apparatus according to the present invention is a photographing apparatus having a casing that is slidably installed, and the sliding contact between the casing and the photographing apparatus. When the contact surface is coated, a sliding sheet is attached to one of the sliding contact surfaces, and a protrusion is provided on the other sliding contact surface. Therefore, even when the casing and the photographing apparatus are in sliding contact, friction between the sliding contact surfaces can be reduced. Therefore, it is possible to protect the sliding contact surface, maintain the beauty of the photographing device, and extend the use durability.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a sliding contact surface protection structure for a photographing apparatus according to an embodiment of the present invention. A video camera is exemplified as the photographing device. The video camera includes a video camera body 1, a viewfinder 2 and a liquid crystal panel 3. A finder 2 as a housing is slidably installed on the video camera body 1. The viewfinder 2 can perform a rotation tilt (up and down) operation in the direction indicated by the arrow a around the rotation axis 4. The liquid crystal panel 3 installed in the video camera main body 1 can be opened and closed in the direction indicated by the arrow b around the rotation shaft 5.
[0010]
A protrusion 8 is provided on the sliding surface 7 of the liquid crystal panel 3. The protrusion 8 is preferably formed in a spherical shape. Further, at least one of the protrusion 8 and the sliding contact surface 7 of the liquid crystal panel 3 or the sliding contact surface 6 of the finder 2 is coated for aesthetics and appearance protection. When the sliding contact surface 6 of the finder 2 is coated, the sliding sheet 9 is stuck on the coating film applied to the sliding contact surface 6. In the case of the video camera shown in FIG. 1, the sliding sheet 9 is formed in an arc shape along the rotation direction of the finder 2. The sliding sheet 9 is made of a material having a very low friction coefficient such as ultra high molecular weight polyethylene.
[0011]
Next, a video camera photographing method using the structure of the present invention will be described. In this photographing method, the finder 2 is used. The liquid crystal panel 3 is located at the position b1 and is closed. In the case of this photographing method, the subject is recognized by looking into the finder 2. The finder 2 can be freely rotated and slid along the direction of the arrow a from the position of the reference sign a1 in the horizontal state to the position of the reference sign a2.
[0012]
FIG. 2 shows a state in which the liquid crystal panel 3 is closed. At this time, the protrusion 8 provided on the sliding contact surface 6 of the finder 2 and the sliding sheet 9 attached to the sliding contact surface 7 of the liquid crystal panel 3 come into contact with each other. Therefore, when the finder 2 is rotated and slid along the direction of the arrow a with the liquid crystal panel 3 closed, the protrusion 8 and the sliding sheet 9 are in sliding contact.
[0013]
In the photographing method that does not use the finder 2, the liquid crystal panel 3 is opened to the position b2. The subject is recognized by looking at the liquid crystal panel 3.
[0014]
According to the first embodiment, the protrusion 8 provided on the sliding contact surface 7 of the liquid crystal panel 3 and the sliding sheet 9 attached to the sliding contact surface 6 of the finder 2 are in sliding contact. Accordingly, since the friction between the sliding surfaces can be reduced, it is possible to prevent the sliding surfaces 6 and 7 from being scratched. Furthermore, it is possible to prevent the paint film applied to the sliding contact surface 7 and / or the sliding contact surface 6 from being peeled off. In particular, when the casing of the video camera is made of, for example, metal, it is effective because it can prevent the paint film on the surface from peeling off and rusting. Further, even when the housing of the video camera is made of, for example, plastic, the sliding contact surfaces 6 and 7 are prevented from being scratched by sliding, and the aesthetic appearance is maintained. As a result, it is possible to provide a photographing device with an improved texture by painting on the sliding contact surfaces 6 and 7. Further, it is possible to prevent the appearance of the photographing apparatus from being troubled and to extend the durability of use of the photographing apparatus.
[0015]
Moreover, since the protrusion part 8 is formed in a spherical shape, friction with the sliding sheet 9 can be suppressed to a lower level, and smooth sliding is possible.
[0016]
FIG. 3 is a perspective view of a photographing apparatus used in the second embodiment of the present invention. In the video camera which is the photographing apparatus shown in FIG. 3, the finder 22 performs a sliding operation that slides in the direction indicated by the arrow c. The sliding sheet 29 is affixed to the sliding contact surface 26 of the finder 22. In this case, the sliding sheet 29 is formed in a horizontally long shape along the sliding direction of the finder 22.
[0017]
According to the second embodiment, the same effect as that of the first embodiment can be obtained.
[0018]
In addition, a sliding sheet 29 having an appropriate shape can be attached to each of the sliding contact surfaces 6 and 26 in response to the sliding operation of the viewfinders 2 and 22 that varies depending on the photographing device. Therefore, it is possible to easily provide a sliding contact surface protection structure that can correspond to various shapes of photographing devices at low cost.
[0019]
In the above-described embodiment, a video camera is used as a photographing device. However, the present invention is not limited to this, and a photographing device having a casing such as a slidable finder such as a digital still camera is widely used.
[0020]
【The invention's effect】
As described above, according to the present invention, it is possible to protect the sliding contact surface of a photographing apparatus having a casing that is slidably installed, thereby extending the use durability of the photographing apparatus.
