のには好適である。The main body of the cartridge is made up of multiple parts that can accommodate the spool inside. Traditionally, these parts were made of metal, but Japanese Patent Application Laid-Open No. 50-3383
The photographic film cartridges described in No. 1 and JP-A-57-190948 are made of resin. In such a photographic film cartridge, since the parts are made of resin, the cartridge main body can be assembled by ultrasonic welding. This ultrasonic welding method can join the joint surfaces uniformly and with high dimensional accuracy by irradiating the joint surface with ultrasonic waves once from a direction perpendicular to the joint surface, and does not require adhesive, so the adhesive can be applied to the joint surface. This method is suitable for products that are manufactured in large quantities, such as photographic film cartridges, because it saves time and effort.

The inner circumferential ribs 20, 21 abut against the outermost circumferential surface of the film roll 6a to prevent loosening of the film roll. Guide ribs 20a and 21a are formed at the other ends of the ribs 20 and 21 to guide the tip of the film 6 peeled off from the outermost peripheral surface toward the film path 10. Furthermore, a tip separation claw 22 is formed on the film roll 6a side of the guide lip 20a to separate the tip of the film 6 from the outer peripheral surface of the film roll 6a.

First, to describe the different manufacturing methods, the first manufacturing method is to irradiate ultrasonic waves from the arrow B direction and then from the arrow A direction, and under other conditions, such as pressing the casings 3 and 4. Fixing pressure, ultrasonic irradiation time, pressure after irradiation,
The fixing time is the same as the conditions used in the method for producing a photographic film cartridge of the present invention. In the second manufacturing method, the pressure for pressing and fixing the casing 3.4 was set to 200 psi, ultrasonic waves were irradiated from the direction of arrow C for 0°3 seconds, and the casing 3.4 was fixed continuously for 0.3 seconds.

．． The dimensional accuracy of the joint surfaces of the second port portions 11 and 12 deteriorated, and variations occurred in the dimensions. As a result, the leading end of the film 6 may get caught in the film path 10, or light may leak from the film path 10.

た。Further, in the photographic film cartridge manufactured by the second manufacturing method, the resin flowed out from a part of the joint surface, and the resin did not melt, so that the joint surface could not be uniformly welded. For this reason, photographic film cartridges manufactured by this manufacturing method were not usable.

Since the port parts can be joined with high dimensional accuracy, it is possible to manufacture photographic film cartridges that allow film to be fed smoothly.
