Abstract

PURPOSE:To open or decompose a principal mechanism part by allowing a front cover which covers the front surface of a camera among outer package covers to be separated from a main body side cover. CONSTITUTION:The main body side cover 5 where boundary surfaces 5a and 5b with the front cover 7 are formed is fitted to the top surface of a camera body 1 while covering a mirror box unit 4. When the front cover 7 is fitted and fixed to the camera body 1, a main body cover step part 9a provided in front of the accessary shoe fitting part 9 of the main body side cover 5 and the roof type part 8 of the front cover 7 are clamped with a small screw for the upper part, the hole 7d of the front cover 7 and the projection 6a of a winding-up base plate are clamped for the lower part, and a hole part 7c and the screw hole 4b of a mirror box unit 4 are clamped for the intermediate part respectively. Therefore, the front cover 7 is easily detached from the camera body 1 even after the assembly of the camera by loosening small screws, and the mirror box unit 4, etc., are adjusted only by detaching the front cover 7.

Description

[Detailed description of the invention]

[ν (uplift)) Single-lens reflex camera field 1 The present invention relates to classification l of exterior parts that make up the exterior of a single-lens reflex camera;

[Regarding this and its mounting structure.] [Conventional technology]

Generally, the exterior parts of a small single-lens reflex camera that uses 35mm film (J135) are the main body side cover that covers the top of the camera including the tape, the bottom cover that covers the mechanism on the bottom of the camera, and so on. It consists of a 70-piece cover attached to the front plate sandwiched between the covers, and an Ik lid that can be opened and closed on the back. Both the main body side cover and the bottom cover are fitted not only into the camera body but also into the aforementioned front plate part, and the main body side cover is fitted with a vent tag fixed to the mirror box unit integrated with the front plate part. Since it covers the rhythm, in order to remove the mirror box unit or the shutter unit installed behind it, it is necessary to remove the front cover, the aforementioned body side cover, and bottom cover in advance. However, there is a winding lever and a winding lever on the top of the cover on the main body side.
1. The ISO dial, shutter speed dial, etc. are attached to the camera body side with the body side cover in between.
In addition, the bottom cover also holds the rewind button, etc., so removing the main body cover and bottom cover involves removing many parts, which saves time and effort when assembling and repairing the camera. The reality is that this is a huge burden on many people. [Problems to be Solved by the Invention] The present invention makes it possible to take out the mirror box unit and shutter unit of a single-limit reflex camera by simply removing the front cover that covers the front of the camera without removing the main body side cover and the bottom cover. The purpose is to provide an exterior for a single-lens camera. [Means for solving the problem of gap] The present invention provides a front cover that covers the front of the camera, with the front cover attached to the mirror box unit being partially attached to the mirror box unit up to the 5th position in the upper direction, and attached to the camera body in the bottom direction. The upper part is connected to the main body side cover, and the bottom part is in contact with a part of the winding base plate, and is tightened with machine screws. It is configured so that it is integrated with the camera body.
It extends the front cover that covers the front of the camera inside the exterior cover to the roof-shaped part that covers the pentaprism.
Both are characterized by forming a boundary with the main body side cover on the top surface of the camera and being separable from the main body side cover.
This is accomplished by using a V-eye camera. [Example] An example of the present invention is shown in FIGS. 1 and 2. FIG. 1 shows the structure of the exterior cover of a single-lens reflex camera according to the present invention, in which the camera body l is pivoted to a hinge 2a of the back cover 2 on a hinge 2a on the back of the camera body l so that it can be opened and closed. When installed, the camera body 1 is locked by engaging the hook 2b of the back cover 2 with a tightening claw (not shown) placed on the side surface of the camera body 1. In some image frames on the front of the camera body 1, there are three shutter units 3 shown in FIG. 2 (only two are shown).
The mirror box unit 4 is installed by tightening the hole 3a provided at each of the holes 3a and the screw hole IC with a small screw, and the mirror box unit 4 is installed by tightening the hole 3a provided at each of the four locations and the screw hole 1 with a machine screw.
d and are fastened with machine screws. Further, on the top surface of the camera body 1, a body side cover 5 is attached to cover the rear half of the pentaprism of the mirror box unit 4, and has interfaces 5a, 5b, etc. with a front cover 7, which will be described later, on its flat surface. The shutter speed dial, winding lever, ISO dial, rewinding shaft, etc. are arranged in each mounting part provided on the flat surface, and are connected to each m+:q part in the camera body i and are mounted. ing. Further, a bottom cover 6 is attached to the bottom of the camera body 1 with the protrusion 6a of the winding base plate protruding. By configuring the exterior of the camera body 1 except for the front part as described above, the front cover 7 attached to the front surface of the camera body 1 can be configured as follows. t 7', Cb The front cover 7 is attached to the camera body 1
covers the front surface of the
a, 7b are joined to the boundary surfaces 5a, 5b, etc. of the main body side cover 5, and the central part thereof is further extended to cover the front half of the venta grism of the mirror box unit 4.
is formed. On the other hand, the lower end of the front force bar 7 is also extended to cover the side edges of the bottom cover 6, and the left and right side ends are respectively fitted to the left and right side walls 5C15d hanging down from the main body side cover 5. The front part of the camera body 1 can be completely covered. The front cover 7 is fixed to the camera body by a main body cover stepped portion 9a provided in front of the accessory shoe attachment portion 9 of the main body side cover 5 at the upper part.
and the roof-shaped part 8 of the front cover 7, while in the lower part, the hole 7d of the front cover 7 and the above-mentioned protrusion 6a of the winding base plate, and in the middle part, the hole 7C and the screw of the mirror box unit 4. The holes 4b are each tightened with machine screws. Therefore, even after the assembly of the camera is completed, the front cover 7 can be easily removed from the camera body 1 by releasing the aforementioned screws. As a result, the mirror box unit 4 and the shutter unit 3 can be adjusted or taken out simply by removing the front cover 7, and the main body side cover 5 and the bottom cover 6 can be removed.
There is no need to remove the winding V-bar, return shaft, 180 dial, shutter speed dial, etc. attached to the end, making assembly and disassembly work extremely easy. [Effects of Claims] According to the present invention, by removing only the front cover among the exterior members, main mechanical parts such as the mirror box unit and shutter unit can be opened or disassembled, which is very convenient for assembly and repair. Naru et al. 1. Even after the development was completed, a single reflex camera with many features such as the ability to easily replace the front cover with a different design or brand was realized.
