DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for attaching a label to a film unit with a lens, and more particularly to a method for attaching a label to a film unit with a lens with improved disassembly.

[0002]

2. Description of the Related Art A film unit with a lens (hereinafter, referred to as a film unit) is commercially available from the present applicant so that photographers can enjoy photography at low cost. This film unit is a unit in which an unexposed photographic film and an exposure mechanism are built in advance, and the unit body is covered with an exterior body such as a paper box. It is widely used in general because of its simplicity that it only needs to be sent to a developing dealer.

The unit main body is composed of a main body base on which a photo film is loaded, a front cover attached so as to cover the front side of the main body base, and a rear cover attached so as to cover the back side of the main body base. And in general,
Plastic molded. On the outer peripheral surface of the main body, there are a photographing lens, a finder lens,
In addition to an exposure opening for exposing a film counter display or the like to the outside of the main body, various openings are provided which are necessary for molding or function and do not need to be exposed to the outside of the main body.

On the other hand, film units are
It is essential that recycling and recycling are actively promoted, and that the main components of the used film unit be maintained in good condition. For this reason, an exterior label is used to protect the surface of the film unit, and in general, a paper exterior layer having a cosmetic print on the surface is cut in accordance with the shape of the unit main body to correspond to the exposed opening. An opening is provided at the location. Then, a pressure-sensitive adhesive for bonding the main body is applied to the back surface of the exterior label, and is attached to the outer peripheral surface of the main body.

[0005] Reuse of this film unit,
For efficient recycling, the process of removing the front and rear covers from the base of the main body is automated. Also, for film units that have an exterior label attached across a part of the assembly boundary between the front and rear covers, do not remove the exterior label from the unit body before removing the front or rear cover. Not be.

However, in order to peel the external label from the unit body, it is necessary to position the jig for peeling the label with high precision and to move the jig slowly. For this reason, in Japanese Patent Application Laid-Open No. 2000-122239, a label cutting device that irradiates a laser beam is used. , The front cover and the rear cover are removed from the film unit. Further, in this case, the outer labels attached to the front cover and the rear cover are formed based on a plastic film compatible with plastic, and are crushed and recycled together with the front cover and the rear cover.

However, the front cover and the rear cover cannot be easily removed from the film unit unless they are cut exactly on the assembly boundary. For example, when cut behind the assembly line, the exterior label ahead of the cut line sticks to the rear cover, preventing removal of the front cover and the rear cover from the film unit. Similarly, when cut at the front of the assembly boundary line, the exterior label behind the cut line may be attached to the front cover. For this reason, it is necessary to use a high-precision label cutting device capable of cutting accurately on the assembly boundary line.

For this reason, there has been proposed a film unit in which a tapered concave portion is provided at the assembly boundary line, and the outer label is cut by irradiating a laser beam above the concave portion. Since the exterior label is not attached to the unit body above the concave portion, when the external label is cut above the concave portion,
The exterior label ahead of the cutting line does not adhere to the rear cover, or the exterior label behind the cutting line does not adhere to the front cover, and the front cover and the rear cover can be easily removed from the film unit.

[0009]

However, the above-mentioned film unit with a lens has a drawback that the thickness of the concave portion is reduced, the resin is liable to be insufficiently wrapped around, and the defective production rate of the product is increased. there were. In order to prevent this, the surface on which the concave portion is formed must be provided thickly, and the size of the film unit is increased by a small amount unnecessarily.

According to the present invention, without increasing the size,
An object of the present invention is to provide a method for attaching a label to a film unit with a lens which can be easily disassembled.

[0011]

In order to achieve the above-mentioned object, a method for attaching a label to a film unit with a lens according to the present invention is characterized in that a boundary area that comes into contact with a periphery of an assembly boundary between a front cover and a rear cover is defined by the unit body. An outer label which is non-adhesive or peelable and has an adhesive applied to a contact surface with the unit main body except for a boundary region thereof is wound around the outer peripheral surface of the unit main body.
