Problems solved by technology
However, in existing film packs having a gripping portion that protrudes or protrudes from the front of the cassette cavity, it is difficult to slide the protective cover
Even if a slidable protective cover could be provided, it would certainly increase the thickness of the film unit housing

Embodiment Construction
[0040] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
[0041] exist figure 1 Among them, a film unit 2 is provided with a winder wheel 3 exposed outside, a shutter button 4, a flash 5, a flash charging switch 6, a photographing lens 7, a viewfinder objective window 8, a charging status display 9 and A frame counter window 10 . A bottom cover 12 for taking out the exposed film strip is provided on the lower left side of the film unit in the figure and extends beyond the front bottom corner of the film unit 2 toward the lower part of the left front area 11 of the film unit 2 .
[0042] A protective cover 13 for protecting the taking lens 7 is provided on the front side of the film unit so as to be slidable in the horizontal direction or the longitudinal direction of the film unit 2 . The protective cover 13 is formed of plastic material as an integral part, and has hook-shaped portions at its upper and lower ends. ...

A lens-carrying film unit having a protective cover, comprising a protective cover (13) for a photographing lens, which is provided at a front side of a lens-carrying film unit and interlocked with a shutter lock mechanism adapted to lock a shutter button (4) when the protective cover is moved to a closing position at the front side of the photographing lens, and which is also interlocked with a flash prevention mechanism adapted to turn off a flash charging switch (6) when the protective cover is moved to the closing position, prevent the flash charging switch from being moved to an ON position while the protective cover is in the closing position, and enable the flash charging switch to be moved to the ON position when the protective cover is moved back from the photographing lens, the protective cover being adapted to slide horizontally in a front region, which extends linearly in a horizontal direction, of the film unit and having a longitudinal length which does not prevent the opening and closing of a bottom cover (12) provided for taking out an exposed photographic film, a first label pasted on a front surface of the protective cover and a second label wound around the film unit keeping out of the front region in which the protective cover is slid enclosing and dustproofing the film unit and reinforcing a unit housing.
Description
technical field [0001] The present invention relates to a lens-fitted photo film unit with a protective cover movable between a closed position covering the taking lens and an open position exposing the taking lens. Background technique [0002] A lens-fitted photo film unit is known as a device that is factory-set with a simple exposure mechanism and houses an unexposed photo film cassette so that anyone can enjoy photography without having to Hassle loading and rewinding. Hereinafter, the lens-fitted photo film unit will be referred to as a film unit. [0003] In order to improve portability, film packs have been made smaller and more compact. Also, a film unit incorporating an IX240 type film cassette which is smaller than a 135 type film cassette has recently been manufactured and sold on the market. Since the IX240 type film cassette is installed, the film unit can be designed to be smaller than the unit equipped with the 135 type film cassette. [0004] Small film ...
