Abstract
Abstract A camera comprises a camera body which is integrally formed with a lens barrel containing a lens having an optical axis. A receiving chamber for receiving an elongated electronic flash body is formed along the lateral side of the lens barrel in parallel to the optical axis of the lens. The electronic flash body having top and bottom ends is provided at its one side with a light emitting window located near the top end thereof. The flash body is built into the camera body through a pop-up means so as to be moved between a first position at which substantially the overall length of the flash body is received into the receiving chamber in the state that the light emitting window is oriented downward and that the bottom end of the flash body is located in the rear end portion of the receiving chamber, and a second position at which the flash body is raised upward from the camera body in the state that the light emitting window is oriented forward and that the bottom end of the flash body is located in the front end portion of the receiving chamber.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
210 words
A camera comprising: a camera body which is integrally formed with a lens barrel containing a lens having an optical axis, and which defines a receiving chamber extending along a lateral side of the lens barrel in parallel to the optical axis of the lens, the receiving chamber having front and rear end portions and being open forward and upward at the front end portion thereof; and an elongated electronic flash body having top and bottom ends and provided at its one side with a light emitting window located near a top end thereof, the flash body being built into the camera body through a pop-up means so as to be moved between a first position at which substantially the overall length of the flash body is received into the receiving chamber in a state that the light emitting window is oriented downward and that the bottom end of the flash body is located in the rear end portion of the receiving chamber, and a second position at which the flash body is raised upward from the camera body in a state that the light emitting window is oriented forward and that the bottom end of the flash body is located in the front end portion of the receiving chamber.
Claim 2
Dependent Claim
210 words
A camera comprising: a camera body which is integrally formed with a lens barrel containing a lens having an optical axis, and which defines a receiving chamber extending along a lateral side of the lens barrel in parallel to the optical axis of the lens, the receiving chamber having front and rear end portions and being open forward and upward at the front end portion thereof; and an elongated electronic flash body having top and bottom ends and provided at its one side with a light emitting window located near a top end thereof, the flash body being built into the camera body through a pop-up means so as to be moved between a first position at which substantially the overall length of the flash body is received into the receiving chamber in a state that the light emitting window is oriented downward and that the bottom end of the flash body is located in the rear end portion of the receiving chamber, and a second position at which the flash body is raised upward from the camera body in a state that the light emitting window is oriented forward and that the bottom end of the flash body is located in the front end portion of the receiving chamber.
Claim 3
Dependent Claim
96 words
A camera according to claim 1, wherein the pop-up means comprises: a pushing means for moving the bottom end of the flash body from the rear end portion to the front end portion of the receiving chamber, the pushing means being adapted to apply a pushing force to the flash body near the bottom end thereof; and a guide means for raising upward the flash body from the camera body by utilizing the pushing force of the pushing means when the bottom end of the flash body approaches the front end portion of the receiving chamber.
Claim 4
Dependent Claim
104 words
A camera according to claim 2, wherein the guide means comprises: a stopper member disposed in the front end portion of the receiving chamber and fixed to the camera body; and a stopper pin fixed to the flash body at a position near the bottom end of the flash body so as to be abutted on the stopper member at a position which is spaced forward and upward from a point of action of the pushing force of the pushing means in relation to the flash body when the bottom end of the flash body approaches the front end portion of the receiving chamber.
Claim 5
Dependent Claim
92 words
A camera according to claim 3, wherein the guide means further comprises: a guide plate which defines therein an elongated guide slot extending between the front and rear end portions of the receiving chamber and which is integrally formed with the stopper member; and a guide pin fixed to the flash body at a position near the bottom end of to the flash body and slidably engaged with the guide slot of the guide plate, the pushing force of the pushing means being applied to the flash body through the guide pin.
Claim 6
Dependent Claim
95 words
A camera according to claim 2, further comprising: a lock member, supported by the camera body, for locking the flash body in the first position against the pushing force of the pushing means, the lock member being forced by a bias spring so as to engage with the flash body when the flash body is located at the first position; and a releasing member supported by the camera body and adapted to push the locking member against the spring force of the bias spring so as to release the locking member from the flash body.
Claim 7
Dependent Claim
23 words
A camera according to claim 2, wherein the pushing means is a bias spring disposed between the camera body and the flash body.
