In the present invention, the front case and the rear case are mainly made of hardwood kraft pulp (L material), and it does not matter whether bleached pulp (LBKP) or unbleached pulp (LUKP). Since the case of the present invention is mainly composed of hardwood kraft pulp, it is desirable that about 80% of the pulp composition is hardwood pulp, but 10 to 20% of softwood pulp (N material is used in order to improve physical strength. ) May be blended. Papermaking slurry using this pulp in the present invention,
In addition to the above pulp raw material, a sulfuric acid band of about 0.1 to 0.3% is blended, and PH is controlled to 7 to 8 for papermaking. When papermaking without pH control, after resin impregnation,
After thermosetting, cracks may occur. In carrying out the present invention, the paper machine is not particularly limited, and a Fourdrinier paper machine, a cylinder paper machine, a Yankee paper machine or the like can be used. The beating degree is about 500 to 550 cc (Canadian freeness), and the basis weight is 50 to 1000 g / m 2, preferably 100 to 230 g / m 2 . The thermosetting resin impregnated into the sheet-shaped pulp base material is not particularly limited,
Diallyl (iso) phthalate resin, resol type phenol resin, novolac type phenol resin, epoxy resin,
It is appropriately selected from melamine resin, acrylic resin and the like. Further, the impregnated amount of the thermosetting resin is required to be 10 to 30% by weight with respect to the absolute dry weight of the sheet-shaped pulp base material, and if less than 10% by weight, the hygroscopicity and physical strength of the case will be considered. Cause problems. On the other hand, when the amount is more than 30% by weight, the amount of the resin is large, so that the calorie becomes too high when incinerated at the time of disposal after use, and too many components remain without being decomposed in the ground, which is not preferable.

In order to three-dimensionally mold resin-impregnated paper into a box-shaped paper case (front case, rear case), the resin-impregnated paper is once molded by an automatic box-making machine or a mold, and then heat-treated to cure the resin. Alternatively, it may be heat-treated and cured at the same time when it is made in a box by a box making machine. The latter is preferable in order to prevent cracks at the corners. In addition, an acrylic-based or epoxy-based adhesive may be used to join the corners in the box-making process, but considering that it is integrated with the main unit after the camera unit is built in, it is recommended to use volatile components as much as possible. Solventless adhesives are preferred. Further, in order to prevent the influence of the volatile component of the adhesive in a high temperature atmosphere, it is preferable to use physical fitting without using an adhesive for the joining.

According to the present invention, the main body is conventionally made of a plastic case, and only the main body case equipped with a photographing mechanism can be reused by simply changing the film, so that the discarded portion is reduced and the cost is reduced. In addition, the reuse part has no change in production equipment, production materials, etc., and no problems occur in production management. Also, since the front case and the rear case to be discarded are mainly made of paper materials, they are light in weight and low in cost, and can be burned with low calorie even when they are disposed of. There is no risk of damage, and even when it is buried in the ground, it can be easily decomposed by bacteria, so that the problem of pollution is extremely small.
