Abstract

PURPOSE:To dust off a lens and to clear the lens by blowing off dust by providing the lens cap main body with feather which dusts off the lens and an air pump which blows off the dust disturbed by the feather. CONSTITUTION:The feather 6 attached to a supporting bench 7 integrated with the lens cap main body 3 can be right and left slided and moved, and a stick 5 for the feather is moved when the dust of the lens part is removed. At the next stage, for blowing off remaining dust and waste dropped near the lens, the air pump 8 is operated by depressing the lever part 7a of the edge of the supporting bench. Then air is injected from a nozzle 9 and the lens is cleaned. Thus lens cleaning is performed only by the lens cap and a camera lens, the lens of a camera integral VTR, etc., can be cleaned any-time and anywhere.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to cleaning lenses in machines and instruments that use lenses.

[Conventional technology]

Figure 5 shows various devices having conventional lenses. 1 is the main body of the device, 2 is the lens, and 3 is a simple dish-shaped lens cap. By attaching this in front of the lens 2, the lens It prevents damage and protects it from chips and debris.

That is, the lens cap 3 is fitted onto the tip of the lens 2 to protect it when the lens 2 is not in use, and is removed when the lens is in use.

[Problem to be solved by the invention]

Conventional equipment is configured as described above, so cleaning the lens requires removing dust with a separately prepared feather, and the lens is prone to dew condensation when you blow on it. There was a problem with it being put away.

This invention was made in order to solve the above-mentioned problems, and its purpose is to make it possible to remove dust attached to the lens itself, and also to blow it away to clean it.

[Means to solve the problem]

In the lens cap according to the present invention, the lens cap body is equipped with feathers for removing clumps and the like, and an air pump for blowing away dust disturbed by the feathers.

[Effect]

The lens cap according to the present invention uses feathers attached to the lens cap body to remove dust attached to the surface of the lens, and blows away remaining dust using an air pump.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure and Fig. 2, 3 is a dish-shaped lens cap body;
4 is a cleaning tool installed inside the cap body 3. 5 is a stick having a feather 6 at the tip, and this stick is attached to a support base 7 which is made integrally with the cap body 1.
It is fitted in a slidable manner. 8 is an air pump installed inside the support base 7 and used to blow away dust, and 9 is a nozzle at the air outlet thereof.

Note that the support stand 7 also serves as a lever for operating the air pump 8.

Next, the operation will be explained. The feathers 6 attached to the support stand 7, which is integrated with the lens cap body 3, can be moved by sliding left and right as shown in FIGS. To remove it, move the feather stick 5 as shown in Figure 3. Next, press down on the lever part 7a at the end of the support base to blow away any dust or dirt that remains or has fallen near the lens. The air pump 8 is activated to inject air from the nozzle 9 to clean the lens. Fig. 4 shows how to actually use the lens cap, as shown in the figure, remove dirt, dust, etc. from the lens 2 by holding the lens cap body 3 by hand with the feather 6 outside. In this case, there is no need to blow on the air like in the past, so there is no need to worry about condensation.

〔Effect of the invention〕

As described above, according to the present invention, lenses can be cleaned using only the lens cap, anytime and anywhere.
It is possible to clean the lenses of cameras, camera-integrated VTRs, etc., and since there is no need to blow on them, the problem of dew condensation is eliminated.

[Brief explanation of drawings]

1 to 4 show an embodiment of the present invention, in which FIG. 1 is a perspective view of a lens cap, FIG. 2 is a sectional view thereof,
3 and 4 are explanatory diagrams of the operation, and FIG. 5 is a perspective view showing a state in which a conventional lens cap is attached. In the figure, 3 is a lens cap body, 4 is a cleaning tool, 5 is a stick, 6 is a feather, 7 is a support stand, 8 is an air pump, and 9 is a nozzle. Note that the same reference numerals in the figures indicate the same or equivalent parts.

Claims (1)

[Claims] A cleaning tool is provided inside the dish-shaped lens cap body, and includes a stick that is slidably supported and has feathers at the tip, and an air pump that is installed opposite the stick and uses the stick as an operating lever. lens cap.
