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 having an exterior label attached to the surface of a unit body.

[0002]

2. Description of the Related Art A film unit with a lens is a film unit in which a film is previously loaded into a unit body having a simple photographing mechanism, and the surface of the film unit is covered with an exterior body which also serves as a decoration, for example, an exterior label. It is widely used because it can shoot. 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 attached to the front of the taking lens, and is slidably opened and closed between a closed position for covering the taking lens and an open position for exposing the taking lens. The lens cover is provided with a click mechanism so as to be stable at the closed position and the open position, and is designed so that the lens cover does not move carelessly when carrying or photographing.

On the other hand, the exterior label is made of paper or a thin plastic sheet material, and on the surface thereof, marks or decorative patterns corresponding to the model of the lens-fitted film unit are printed. And in the case of a film unit with a lens provided with a lens cover as described above,
In addition to the front and top surfaces of the unit body, it is also attached to the front of the lens cover, ensuring uniformity in external design.

When a film unit with a lens is shipped from a factory, it is sealed in a dust-proof and moisture-proof packaging bag. As a result, it is possible to prevent dust from entering the inside of the product during transportation or during display at a store, causing a failure, and preventing the photographic characteristics of the film from being deteriorated by the influence of humidity.

[0006]

A film unit with a lens provided with a lens cover is sealed in a packaging bag with the lens cover closed, but when a vibration or impact is applied during transportation or at a store. The lens cover may open. Because of this, the protection of the photographic lens is incomplete, and if you buy it,
When the packaging bag is opened, the lens cover is already open, which may give a sense of incongruity.

[0007] Such a problem can be improved by increasing the locking force of the click mechanism that locks the lens cover in the closed position. It becomes difficult to open the cover, which causes a problem in operability.

[0008] The present invention has been made in view of the above circumstances, without affecting the opening operation of the lens cover,
It is an object of the present invention to provide a lens-fitted film unit that prevents the lens cover from being opened carelessly even if a slight impact is applied during transportation or at a store.

[0009]

In order to achieve the above object, according to the first aspect of the present invention, an outer label composed of one sheet is provided on a boundary between a lens cover at a closed position and a front surface of a unit body. Along the line, a detachable break line is provided, and this exterior label is attached to the unit body, thereby preventing the lens cover from being accidentally moved in the opening direction.

[0010] In the invention according to claim 2, a part of the break line provided on the outer label is separated in advance by a cut line to shorten the break length. Further, in the invention according to claim 3, the exterior label is integrally attached from the front surface to the back surface of the unit main body, thereby increasing the connection strength of the unit main body.

[0011]

FIG. 1 shows the appearance of a film unit with a lens. A film unit 1 with a lens is provided with a photographing mechanism, and a unit body 2 in which a film is loaded in advance.
And an exterior label 3 covering the surface thereof. The unit body 2 includes a photographing lens 4, a shutter button 5, a strobe device 6, an operation knob 7 for winding up a film, a finder objective window 8, a strobe charging start button 9,
The main body in which a number-of-photographs display window 10, a strobe charge display window 11, and the like are incorporated is covered with a front cover 12 and a rear cover 13.

Openings are formed in required portions of the front cover 12, respectively, and the photographing lens 4 incorporated in the base of the main body.
And the shutter button 5 are exposed to the outside. Further, the front cover 12 has a slide operation type lens cover 1.
When the camera is carried, it is closed so that the taking lens 4 can be protected. Further, a bottom cover 15 for taking out a photographed film is provided at the bottom on the left side when viewed from the front of the unit body 2.

On the other hand, the exterior label 3 is formed in a belt shape whose longitudinal direction is substantially perpendicular to the sliding direction of the lens cover 14, and extends from the front to the back of the unit body 2 as shown in FIGS. It is pasted together. Further, the exterior label 3 is composed of two label portions. That is, the cover label portion 3a is applied to the front surface of the lens cover 14, and the unit body label portion 3b is applied to the back surface in a range excluding the lens cover 14 in the closed position, and from the front surface to the back surface of the unit body 2. It is stuck by the applied adhesive.

Each part of the exterior label 3 is provided with an opening, from which the number-of-photographs display window 10, the strobe charging display window 11, the finger hook 14a, and the finder eyepiece 20 are exposed. . On the other hand, the unit body label portion 3b has a portion that overlaps with the bottom cover 15,
If the user tries to open the bottom cover 15 in this state, the overlapping portion becomes an obstacle. For this reason, a perforation 21 is formed on the unit main body label portion 3b so as to be separable at a boundary line of a portion overlapping with the bottom cover 15, and if the unit main body label portion 3b is broken along the perforation 21, The entire surface of the bottom cover 15 is exposed, and the bottom cover 15 can be easily opened.

FIG. 4 is a sectional view of a main part when the lens cover 14 is in the closed position. The internal structure of the unit body 2 is omitted. As shown in FIG.
2 is provided with a click claw 16 integrally protruding forward. The two engaging projections 17 and 18 are formed integrally on the inner wall of the lens cover 14. Engaging projection 17
Engages with the click claw 16 when the lens cover 14 is in the closed position, and another engagement projection 18 engages with the click claw 16 when the lens cover 14 is in the open position. The lens cover 14 does not accidentally move in the opening direction (the direction of the arrow B) due to the engagement between the engagement protrusion 17 and the click claw 16.

A slit 19 is formed at a required portion of the front cover 12 so that when a force is applied to the click claw 16 in the pushing direction, the click claw 16 is moved to the front cover 1.
2 (in the direction of arrow A). At the time of photographing, when the lens cover 14 is slid in the opening direction using a finger hook 14a provided forward of the lens cover 14, the engaging projection 17 pushes down the click claw 16 in the direction of arrow A.

When the engaging projection 17 gets over the click claw 16, the lens cover 14 in the closed position is closed.
