Claims

[Scope of claim for utility model registration] 1. A lens barrel that goes in and out of the camera body,
A lens barrel guide frame that guides the lens barrel and allows the lens and film surface to be adjusted to the correct position within the frame when the lens barrel is extended, and a film receiving plate that guides the travel of the film are integrally constructed. A lens barrel holding device for a collapsible camera, in which a housing is inserted and fixed into the camera body from the back side of the camera body to prevent light leakage. 2. A lens barrel holding device for a collapsible lens barrel camera according to claim 1, which prevents light leakage by interposing a light leakage prevention member between the camera body and the lens barrel frame. 3. A retractable lens barrel camera according to claim 1 or 2 of the utility model registration claim, in which a light leakage prevention member is arranged in a floating manner between the camera body and the lens barrel frame to prevent light leakage. lens barrel holding device. 4. A collapsible lens barrel camera according to claims 1, 2, and 3 of the utility model registration claims, in which the light leakage prevention member disposed between the camera body and the lens barrel frame is made of a flexible, soft material. lens barrel holding device.
