Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a chute for guiding coins from the coin slot of a toll collection machine to a coin validator.

Prior Art A chute for guiding coins from the coin slot of a toll collection machine to a coin validator in a vending machine, etc. is made by superimposing a pair of mold members each having a recessed part bent at an obtuse angle. Meanwhile, a pair of upper and lower coin passage forming cores bent to correspond to the shape of the recess are inserted from the upper and lower ends of the mold member, and a synthetic resin material is integrally injection molded. What has been done is known. In the chute thus formed, one end surfaces of the upper and lower cores inserted as described above are brought into contact with each other, thereby forming a coin passageway having an obtuse angle bent approximately in the middle.

Problems to be Solved by the Invention However, as shown in FIGS. 9 and 10, when molding this type of coin chute, it is not possible to hold the coin passage portions of the upper and lower cores, so the synthetic resin injection pressure etc. This often caused the upper and lower cores to be misaligned along the abutting surfaces, resulting in a step on the coin passage forming surface of the coin chute. Such a difference in level hinders the coin from smoothly sliding down the coin chute and causes the coin to become jammed.

Therefore, an object of the present invention is to provide a coin chute that can be integrally injection molded so that no steps are formed on the coin passage forming surface.

Means for Solving the Problems According to the present invention, in order to achieve the above object, the inner wall constituting the coin passage has a rectangular cross section that serves as a guide for rolling and falling coins, and is made by injection molding. It is a coin chute that is integrally molded, and part of the left and right rising walls corresponding to the coin outer diameter side guides of the first mold member and the second mold member that form the outer wall during molding are used as the side wall part of the coin passage. By overhanging to the inner wall of the coin passage and bringing the first core and second core forming the inner wall into contact with each other so as to be flush with each other in the thickness direction of the coin, the inner wall is formed on a part of the left and right rising walls of the side wall of the coin passage. The coin chute is characterized by having a hole that communicates with the coin chute.
