Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a so-called waterproof / living-type drip-proof / waterproof camera, and more particularly to a drip-proof / waterproof camera having a sounding body that emits a warning sound or the like in a camera body. About the camera.

"Prior art and its problems" The present applicant, in a camera in which the inner volume changes greatly due to zooming or the like, a perforated breathing hole that communicates between the inside and outside of the camera is provided, and a vented water-impermeable filter is provided in this breathing hole. The camera is designed to prevent drastic changes in the internal volume of the camera.
We have proposed a drip-proof and waterproof camera that can be made waterproof. This drip-proof / waterproof camera can perform zooming or focusing without changing the operation force due to a change in the internal volume by balancing the air pressure inside and outside the camera with the breathe hole.

By the way, some cameras are provided with a sounding body for notifying a subject of a release timing at the time of self-timer shooting, for example. However, when this equipment is applied to the drip-proof / waterproof camera, the generated sound is blocked by the camera body, and is hardly transmitted to the outside. For this reason, even if a sound indicating the turning angle and the release timing is issued, a problem such that the sound does not reach the subject occurs.

"Purpose of the invention" The present invention has been made in view of the above-mentioned conventional problems, and even if the camera is drip-proof and waterproof, the sound emitted from the sounding body inside the camera is easily transmitted to the outside. The aim is to get a drip-proof and waterproof camera that can do it.

"Summary of Invention" The present invention relates to a camera having a sounding body in a watertight camera body.
Form a breeze hole that connects the inside and outside of the camera body,
The breathe hole is covered with a gas-impermeable filter, a support member is provided in the camera body at a position close to the breathe hole, and the sounding body is arranged at a position of the support member facing the breathe hole. I do.

Therefore, when, for example, self-timer shooting is performed using the drip-proof / waterproof camera, the sound emitted in the camera body to notify the release timing is easily transmitted to the subject through the breeze hole.

"Embodiments of the Invention" The present invention will be described below with reference to illustrated embodiments. FIG. 2 is a perspective view showing the appearance of the drip-proof / waterproof camera 10 to which the present invention is applied.

The camera body 12 of the drip-proof / waterproof camera 10 is configured to be watertight, and its lens barrel 14 is provided so as to maintain watertightness. This lens barrel 14 is moved forward and backward in the optical axis direction by a pair of zoom switches 30 and 32 installed on the upper surface of the camera body 12 to perform zooming. As a result, the inner volume of the camera body 12 including the lens barrel 14 is increased. Changes. A release button 28 is further provided on the upper surface of the camera body 12. A rear cover 34 is provided on the rear surface of the camera body 12 so as to be freely opened and closed. On the front surface 12a of the camera body 12, there are a light-emitting window 20 for projecting infrared light for distance measurement, a light-receiving window 22 for receiving infrared light reflected by a subject, and an objective window for a finder.
24, a strobe light emission window 26, and a protective cover 35 are provided.

Referring to FIG. 1, the portion where the protective cover 35 is installed will be described in detail. A breeze hole 37 is formed in the front surface 12a of the camera body to communicate the inside and outside of the camera body 12 and balance the air pressure. In front of this breathe hole 37, a ventilation non-water-permeable filter 36 is
Is pasted. A protection cover 35 is provided at a position corresponding to the air-permeable / non-water-permeable filter 36 on the camera body front surface 12a. The protective cover 35 has a large number of communication grooves 35a formed along the circumference thereof.
Allows the filter 36 to contact the outside air, and at the same time protect the filter 36 from scratches, breakage, contamination and clogging.

Also, inside the camera body 12, close to the front 12a,
The camera internal component 39 is installed, and this component
An electric circuit board 40 is provided on the front surface of 39. At a position of the electric circuit board 40 corresponding to the breathe hole 37, a sounding body 41 for notifying a release timing or the like is provided.

Therefore, according to the drip-proof / waterproof camera 10 having the above structure, when the lens barrel 14 is moved forward and backward with respect to the camera body 12, the internal volumes of the body 12 and the lens barrel 14 change.
Then, the air corresponding to the change amount enters and exits the body 12 through the many communication grooves 35a of the protection cover 35, the ventilation / non-water-pass filter 36, and the breathe hole 37. Therefore the lens barrel
The operating force for moving the 14 forward and backward does not fluctuate due to changes in the internal pressure in the body 11 and the lens barrel 14.

For example, when performing self-timer shooting, the sounding body 41 emits a sound immediately before the release to notify the subject of the release timing. This sound wave passes through the breathing hole 37 located immediately in front of the sounding
It easily exits outside through 36 and the communication groove 35a. Therefore, despite the drip-proof and waterproof camera 10 being drip-proof and waterproof, the sound emitted in the camera body 12
It can be reliably transmitted to the outside.

Note that the sounding body 41 described above may be a sounding body that emits a warning sound when focusing is impossible.

"Effects of the invention" As described above, the drip-proof / waterproof camera of the present invention can easily transmit the sound emitted by the sounding body inside the camera body to the outside, even though it is drip-proof and waterproof. it can. Therefore, for example, in the case of self-timer shooting, a sound indicating the release timing can be reliably transmitted to the subject, and problems such as improper shooting due to improper timing can be prevented.
