DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lens-fitted film unit in which a protective tray is enclosed in a packaging bag together with a lens-fitted film unit.

[0002]

2. Description of the Related Art A film unit with a lens to which a film is previously loaded at the time of manufacture is stored in a dust-proof and moisture-proof packaging bag and shipped. This is to prevent dust from entering the product and causing a failure, or to prevent the photographic characteristics of the film from being deteriorated due to the influence of humidity, as well as during transportation or during display at a store. Further, as known in JP-A-8-248573 and the like, a tray is also accommodated in the packaging bag. This tray is
This protects the front of the lens-fitted film unit from impact during transportation, and prevents the push-type flash charging button from being pressed by unexpected external force from outside the packaging bag.

[0003] On the other hand, various types of film units with lenses have been commercialized, and some recent ones have a lens cover to protect the front surface of the photographing lens from dirt and impact when carrying. The lens cover is slidably assembled to the front of the lens-fitted film unit, and is moved between a closed position for covering the taking lens and a position for exposing the taking lens. The lens cover is provided with a click mechanism so as to be stabilized at the closed position and the open position, respectively, and is designed so that the lens cover does not move accidentally when carrying or photographing.

[0004]

For the same reason, a film unit with a lens with a lens cover is shipped together with a tray in a packaging bag, and the lens cover is closed. However, although the click mechanism is attached to the lens cover, the click stops at the closed position during transportation or when vibration or impact is applied at the store, and the lens cover may move to the half open or open position. . As a result, the protection of the photographic lens may be incomplete, and users who have purchased the photographic lens may feel uncomfortable because the lens cover is already open when the packaging bag is opened. Maybe.

It is possible to improve the above-mentioned difficulty by setting the locking force of the click mechanism to be strong. However, if the locking force at the closed position is too high, the lens cover is opened. It becomes difficult, and a problem arises in terms of operability.

The present invention has been made in view of the above circumstances, and a film unit with a lens having a lens cover receives a slight impact during transportation or at a store without affecting the opening operation of the lens cover. It is another object of the present invention to provide a lens-fitted film unit package that prevents the lens cover from being opened carelessly.

[0007]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problem by utilizing a tray enclosed in a packaging bag together with a film unit with a lens at the time of shipment. For this reason, in the present invention, a projection is provided on a tray enclosed in a packaging bag so as to cover the front surface of the film unit with a lens, and the projection is engaged with a part of the lens cover at the closed position to thereby provide a lens. The cover is prevented from moving in the opening direction. Such a protruding piece can be easily provided by bending a part of the tray. Further, in the case where a finger hook is protruded from the front surface of the lens cover for opening / closing operation, a hole into which the finger hook is fitted may be formed in the tray, in order to achieve the object of the present invention. It is an effective means.
