Description

The present invention relates to a multi-function filter frame that is used by being attached to the tip of a lens barrel of a digital camera.

In particular, the present invention provides a shock absorbing function for the filter frame to protect the filter frame and the camera lens barrel from shocks. This is to prevent the optical axis of the camera lens from deviating when the tip of the lens barrel hits a hard object during movement or shooting.

Further, in the present invention, when the filter frame is formed in a thin shape so that the vignetting phenomenon does not easily occur, the thin filter frame is clamped with a fingertip when the filter frame is attached to the lens barrel tip. The filter frame is provided with a filter frame that is less slippery and easy to attach and detach the filter frame. It is an object of the present invention to provide a multi-function filter frame for a digital camera that is configured so that the removal operation can be easily performed without causing the filter frame itself to idle when being removed.

A filter for a digital camera is attached to the tip of a camera lens barrel to absorb light, transmit light, or change light, and control the light to capture an image sensor (optical) The filter frame is a frame containing a filter lens having various functions described above. The filter lens built in the filter frame includes a lens protection filter, a polarizing filter, a light amount adjustment filter and a light effect filter, a soft focus filter that can express a subject softly, and the like.

Thus, as in the present invention, a filter frame with an impact buffering function is attached to the tip of the lens barrel of the camera, and the filter barrel is attached to the tip of the lens barrel while moving to the shooting site or during shooting. A filter frame that functions so as to prevent the optical axis of the camera lens from being deviated by using the filter frame as an impact buffer when hitting a hard object has not been provided as a conventional device.

However, the filter frame that holds the various filter lenses is not easily vignetted even when mounted on a wide-angle lens, a zoom lens, or a telephoto lens as disclosed in, for example, Japanese Patent Application Laid-Open No. 2005-301173 (hereinafter referred to as Patent Document 1). It is disclosed as a thin filter frame.

In the invention of Patent Document 1, a filter outer peripheral frame to which a filter lens is attached has a female screw portion for screwing another optical system attachment on the front surface of the filter outer peripheral frame, and a camera lens mirror to which the female screw outer cylinder side is attached. It has a shape that protrudes slightly from the front of the tube, and has a male threaded portion that is screwed to the tip of the camera lens barrel behind the filter outer frame, and the filter lens is as far back as possible. A filter frame is provided in which the outer peripheral frame of the filter frame can be made thin by being arranged and arranged in the lens barrel of the camera together with the male screw outer cylinder formed by the male screw part.

The invention of Patent Document 1 is thin by engraving a knurled portion engraved on the outer peripheral portion of the outer peripheral frame of the filter and a knurled portion different in knurled pitch engraved on the edge chamfered edge of the outer peripheral frame. However, it is possible to provide a filter frame that can be easily attached to and detached from the tip of the lens barrel.

However, a knurled part is engraved on the outer periphery of the thin filter outer frame so that the filter frame can be easily attached and detached, and a knurled part with a different knurling pitch is engraved on the outer edge of the outer frame with a chamfered edge. The above causes fine processing by a precision machine, resulting in a drawback of significantly increasing the product manufacturing cost.

The filter frame is attached to the tip of the camera lens barrel by attaching a male screw screwed on the outer diameter of the filter frame to a female screw threaded on the attachment screwed on the inner diameter of the lens barrel tip. When the filter frame is removed from the tip of the lens barrel, the removal operation may not be performed even if the knurled portion is held between the fingertips. Has drawbacks. This drawback is also an important issue that must be solved when providing a thin filter frame that is less vignetting.

Thus, the present invention relates to a multi-functional filter frame for a digital camera, and is mounted as a filter frame with an impact buffering function at the tip of a lens barrel of the camera. When the lens barrel tip hits a hard object while the camera is moving or shooting, the filter frame acts as a buffer material for the filter frame itself or the camera lens barrel so that the optical axis of the camera lens is not deviated. belongs to.

In addition, even when the filter frame is configured in a thin shape so that the vignetting phenomenon does not easily occur, the fingertip can be used when the thin filter frame is attached to the tip of the lens barrel. The filter frame that is sandwiched between the lens frame and the outer peripheral portion of the filter frame is difficult to slip, and the filter frame is easy to attach and detach. It is an object of the present invention to provide a multi-function filter frame for a digital camera configured so that the removal operation can be easily performed without rotating the filter frame itself when removing from the tip.
