Hereinafter, the same reference numerals as those shown in the drawings denote the same members having the same function.

The flash 206 is provided with a flash housing 207. The flash housing part 207 is a hollow semi-cylindrical shape with one side open. A protective glass 211 is installed in the opening 207a of the flash housing 207. The protective glass 211 is preferably made of a diffusing plate for preventing breakage of the bulb 209 and diffusing the light emitted from the bulb 209 to the outside.

A reflection shade 208 is installed inside the flash housing 207. The reflector 208 has a hollow semi-cylindrical structure, and a reflective layer 212 is formed on the inner wall of the reflector 208 to reflect light emitted from the bulb 209 forward. The reflective layer 212 can be formed by coating a material such as aluminum (Al) or silver (Ag), which is excellent in reflectivity against light, or by attaching the material in a thin film form.

A bulb 209 is provided in the reflector 208 to emit light when an external signal is applied thereto. The bulb 209 is made of a discharge tube sealed with xenon gas (Xe gas).

Alternatively, the reflective layer 212 may be directly formed on the inner wall of the flash housing part 207 without installing the reflector 208, and the bulb 209 may be provided inside the flash housing part 207 It is not.

At this time, a rotary member 213 is installed on one side wall of the flash housing 207. The rotary member 213 has a plate-shaped main body portion 301 having an area relatively larger than the side wall area of the flash housing portion 207 and a plate-shaped main body portion 301 integrally extending downward from the bottom center of the main body portion 301 And a bent portion 303 bent in the vertical direction from the bridge portion 302 toward the flash housing portion 207. Needless to say, the rotary member 213 is not limited to the above-described embodiment, and may be formed in various shapes.

The bent portion 303 is hinged to the camera main body 201 (see FIG. 2) by the rotation portion 304, and is rotatable in the left and right directions as shown by an arrow. For example, the bending portion 303 may be formed at the bending portion 303 as a rotation center, such as a pin joint, a ball socket joint, a universal joint, or a roll joint, 213 are rotatable in the left-right direction, the present invention is not limited to any one combination.

A knob 305 is provided on the back surface of the main body 301, that is, on the opposite side to the facing surface of the flash housing 207. The knob 305 is rotatably coupled to a knob guide or the like through a through hole formed in the main body 301 and is coupled to the rotation shaft 306 through the main body 301. The end of the rotation shaft 306 is coupled to the side wall of the flash housing part 207. Accordingly, when the knob 305 is rotated as indicated by an arrow, the flash housing part 207 is rotatable in the vertical direction.

A scale 307 is displayed on the outer peripheral surface of the knob 305 and a reference display point 308 is displayed on the back of the main body 301. The scale 307 indicates an angle at which the flash housing 307 rotates when the knob 305 is rotated in one direction. For example, if the scale 307 indicates 0 degree, the flash housing unit 207 rotates toward the front portion. If the scale 307 indicates 45 degrees, the flash housing unit 207 rotates upward by 45 degrees. And when the flash housing part 207 indicates 90 degrees, it means that the flash housing part 207 rotates toward the vertical upper part.

The reflector 208 is preferably positioned in the flash housing 207 and rotates on the coaxial axis when the flash housing 207 rotates. However, the reflector 208 is not necessarily limited to this, Means may be provided to rotate only the reflector 208.
