Abstract

Abstract In a flash device having the body part thereof arranged to be turnable relative to a fixed or stationary part which includes a mounting part for mounting the flash device on a camera so that the body part can be uplifted when the flash device is to be used and can be bent down toward the lens barrel of the camera for improved portability when the flash device is not in use, an operation member is disposed on the fixed part in such a position as to be covered by the body part when the body part is shifted to a usable position or to an unusable position thereof so that water, etc. can be prevented from entering the inside of the flash device via the operation member while the flash device is used or not used in the rain.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 202 words
A flash device which can be mounted on an accessory shoe part of a camera body, comprising: (a) a mounting part for mounting said flash device on said accessory shoe part of the camera body; (b) a stationary part formed integrally with said mounting part, wherein a display part is arranged at a first position close to said mounting part of the stationary part and an operation member of the flash device is arranged at a second position which is spaced away from the mounting part a greater distance than the first position; and (c) a body part turnably connected to said stationary part, wherein a light emitting part is provided at said body part, said body part being turnable from a usable position to an unusable position relative to the stationary part and having an end portion of the body part located at a position which is higher than the first position and which is positionable to cover the second position when the body part is at a usable position relative to the stationary part, said end portion of the body part being shifted to a position higher than the second position when the body part is at the unusable position.
Claim 2
Dependent Claim 202 words
A flash device which can be mounted on an accessory shoe part of a camera body, comprising: (a) a mounting part for mounting said flash device on said accessory shoe part of the camera body; (b) a stationary part formed integrally with said mounting part, wherein a display part is arranged at a first position close to said mounting part of the stationary part and an operation member of the flash device is arranged at a second position which is spaced away from the mounting part a greater distance than the first position; and (c) a body part turnably connected to said stationary part, wherein a light emitting part is provided at said body part, said body part being turnable from a usable position to an unusable position relative to the stationary part and having an end portion of the body part located at a position which is higher than the first position and which is positionable to cover the second position when the body part is at a usable position relative to the stationary part, said end portion of the body part being shifted to a position higher than the second position when the body part is at the unusable position.
Claim 3
Dependent Claim 254 words
A flash device which can be mounted on an accessory shoe part of a camera body, comprising: (a) a mounting part for mounting said flash device on said accessory shoe part of the camera body; (b) a stationary part formed integrally with said mounting part, wherein an operation member of the flash device is arranged at a predetermined location of said stationary part; and (c) a body part rotatably connected to said stationary part, said body part having a case part which has a shape extended in a direction approximately vertically upward against said stationary part when the device is in an operating position and has a longer length than a length of said stationary part, as well as a light emitting part which is provided on an upper plane of said case part and is arranged in an approximately parallel direction against said stationary part at a time when the device is in said operating position and further is provided integrally with said case part, said case part being bent down in an approximately parallel direction against said stationary part at a time when the device is not in use so that a light emitting plane of the light emitting part faces to an approximately vertically downward direction against said stationary part, said case part being so placed to cover the operation member of said stationary part when it is at an operating position and being moved to a position not to cover the operation member when it is at a nonoperating position.
Claim 4
Dependent Claim 254 words
A flash device which can be mounted on an accessory shoe part of a camera body, comprising: (a) a mounting part for mounting said flash device on said accessory shoe part of the camera body; (b) a stationary part formed integrally with said mounting part, wherein an operation member of the flash device is arranged at a predetermined location of said stationary part; and (c) a body part rotatably connected to said stationary part, said body part having a case part which has a shape extended in a direction approximately vertically upward against said stationary part when the device is in an operating position and has a longer length than a length of said stationary part, as well as a light emitting part which is provided on an upper plane of said case part and is arranged in an approximately parallel direction against said stationary part at a time when the device is in said operating position and further is provided integrally with said case part, said case part being bent down in an approximately parallel direction against said stationary part at a time when the device is not in use so that a light emitting plane of the light emitting part faces to an approximately vertically downward direction against said stationary part, said case part being so placed to cover the operation member of said stationary part when it is at an operating position and being moved to a position not to cover the operation member when it is at a nonoperating position.
