[0002]

2. Description of the Related Art A camera provided with a charging display member at a position distant from the camera so that the user can visually recognize the completion of charging of the strobe device has been disclosed in Japanese Patent Application Laid-Open Nos.
No. 4,951, gazette. In this camera, when the strobe switching knob on the front of the camera body is slid to the ON position, the strobe charging switch is turned ON and the charge display member is moved to the display position. As this charging display member, a prismatic light guide is used. The light guide vertically moves between a projecting position where the tip protrudes from the camera body and a retracted position where the tip enters the camera body. When the main capacitor of the strobe device is charged to a predetermined voltage, the red LED in the camera body blinks. The red light of the red LED passes through the light guide and exits from the tip.

Further, the present applicant has proposed an improved camera provided with the above-mentioned charging display member, wherein the operation of the strobe switching knob is prohibited when the lens cover is set to the closed position (International Patent Publication No. Public number WO
99/18477). In this camera, when the lens cover is set to the closed position, the strobe switching knob is maintained at the OFF position, and is prevented from moving to the ON position. When the lens cover is set at the open position, the strobe switching knob can move freely between the ON position and the OFF position. When the strobe switch is set to the ON position, the strobe charge switch turns on.
Then, the light guide for indicating the completion of charging moves to the protruding position. When the strobe switch is set to the OFF position, the light guide moves to the retracted position, and the strobe charging switch is turned off. If the lens cover is moved to the closed position while the strobe switching knob is at the ON position, the strobe switching knob is returned to the OFF position, and the light guide is moved to the retracted position.

When the strobe device is used for delight photographing, a person's face or the like is overexposed by the strobe light in photographing a normally lit scene. However, since the ratio of the strobe light is small compared to the sunlight, this overexposure is covered by the latitude of the photographic film. For this reason, the influence of overexposure does not appear in a print photograph created from a picture frame of a normally-lit scene shot by flash photography. By the way, when strobe light is used for a backlight scene, it is possible to prevent a person's face from being blackened due to underexposure. Therefore, although the battery is wasted, it is preferable to always use the strobe device for photographing.
