Description

[Detailed Description of the Invention] The present invention relates to a camera equipped with a dust cover that protects the lens.

A cap is now attached in front of the lens to prevent the lens from being scratched or dusty. However, when taking pictures, the cap must be removed from the lens and stored in a pocket or the like, making it inconvenient to handle, so cameras with dust covers have been proposed.

This camera with dust cover has a dust cover on the front of the camera,
In order to cover the upper and lower surfaces, the dust cover is approximately U-shaped, and when the dust cover is slid, the lens and the viewfinder that were covered by the dust cover are exposed.
However, since this dust cover covers much of the outer periphery of the camera, it has the disadvantage of increasing its size and cost.

The present invention solves the above-mentioned drawbacks and aims to provide a camera with a dust cover that is small and inexpensive.

This device has a rotatable dust cover on the front of the camera, an opening is formed in the part facing the lens, and a blind that can be opened and closed can be moved in a straight line along the dust cover. The blind and the dust cover are connected by an L-shaped connecting lever, and when the dust cover is moved to the open position, the dust cover is retracted from the front of the dust cover, and the blind is retracted from the opening of the dust cover. This allows the lens to be exposed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In Figures 1 and 2, camera body 1
has a photographing lens 2, a front view window 3,
A distance measurement window 4, a focus adjustment lever 5, an aperture adjustment lever 6, and a self-lever lever 7 are provided. Further, a release button 8, a rewind crank lever 9, and a hot shoe 10 are provided on the top surface of the camera body 1, and furthermore, a winding knob 11 is provided in the right corner.

A dust cover 13 is provided on the front surface of the camera body 1 so as to be rotatable between a vertical position shown in FIG. 1 and a horizontal position shown in FIG. This dust cover 13 is provided with an opening 14 in a portion located in front of the photographing lens 2. A blind 15 for covering the opening 14 is provided inside the dust cover 13.
is slidably provided.

When the dust cover 13 is in the vertical position,
The finder window 3 and the distance measurement window 5 are shielded, and the blind 15 shields the opening 14. This protects the blind window 3, the distance measuring window 4, and the photographic lens 2 from being scratched or having dust attached to them.

When the dust cover 13 is rotated 90 degrees as shown in FIG. 2, the blind 15 slides and the photographing lens 2 is exposed. Furthermore, by rotating the dust cover 13, the viewfinder window 3 and the distance measurement window 4 are also exposed, allowing photographing.

As shown in FIG. 3, a mounting plate 17 is fixed to the rear end of the dust cover 13. This mounting plate 17
An opening is formed in the center, and the end of this opening fits into a ring-shaped groove 18 provided in the camera body 1 on the outer periphery of the photographic lens 2. Therefore, if the dust cover 13 is rotated, the open end will align with the groove 1.
Rotate along 8.

Inside the dust cover 13, there is an L-shaped 2
A guide frame 19 of the plate is fixed, and this guide frame 1
A blind 13 is slidably held at 9. Both ends of an L-shaped connecting lever 20 are pivotally connected to the blind 13 and the front surface of the camera body 1 with pins 21 and 22, respectively.

FIGS. 4 and 5 show the moving state of the blind. When the dust cover 13 is rotated from the state shown in FIG. 4 to the state shown in FIG. The blind 15 is slid to the right along the guide frame 19 and retreated from the opening 14. When the blind 15 moves, light from the subject enters the photographic lens 2 through the opening 14.

FIGS. 6 and 7 show an embodiment in which two blinds are provided that slide in opposite directions. Two blinds 24 and 25 are slidably held on a guide frame 19. This blind 2
One ends of two connecting levers 26 and 27 are pivotally attached to 4 and 25, and when the dust cover 13 is rotated, they move away from each other and retreat from the opening 14. Note that it is desirable that the ends of the blinds 24 and 25 overlap.

The present invention having the above configuration includes a rotatable dust cover in front of the camera, a blind that opens and closes the opening formed in the part facing the lens, and this blind moves in conjunction with the rotation of the dust cover. This makes the dust cover smaller and cheaper than conventional dust covers. Further, the dust cover partially closes the front surface of the winder to prevent it from being scratched. Furthermore, the blinds
Since it moves in a straight line in conjunction with the dust cover via an L-shaped connecting lever, the width of the dust cover can be reduced, making the whole compact.

Claims (1)

[Claims for Utility Model Registration] (1) A fine dust cover is arranged above the lens, and a rectangular dust cover with an opening formed in the part facing the lens is arranged in front of the lens and the fine dust cover. A pair of guide frames extending in the longitudinal direction are attached to the inside of the dust cover, and a blind is attached so as to be movable in a straight line along the guide frames, and an L-shape is formed between the blind and the camera body. When the dust cover moves from the closed position to the open position, a part of the dust cover is retracted from in front of the window viewr, and the blind is moved in a straight line to open the dust cover. A camera with a dust cover that is characterized by opening the lens to expose it. (2) Utility model registration claim 1, characterized in that two blinds are provided and move linearly in opposite directions according to the rotation of the dust cover.
