[Effects of the Invention] The photoelectric spherical object detection counter of the present invention having the above-described configuration includes a light emitting element and a light receiving element, and allows the object sphere to pass through a reflected light coupling path formed between them. The object sphere is detected by blocking the optical coupling path when the sample passes. In this invention, even if the object sphere is continuously supplied in the state of contacting the contact as shown in FIG. 3, the optical coupling path is the diameter line of the object passage hole, that is, the object passage. Since it is located away from the center point of the hole, the optical coupling path is always formed when the contact point contact portion (P) of the object sphere passes through the optical coupling path. Therefore, each time one object sphere passes, as shown in FIG. 2 , accurate optical signals such as the optical coupling path conduction time t 1 and the optical coupling path cutoff time t 2 are output. Further, unlike the conventional spherical object detection counter in which the outer surface of the object spherical object is used as a reflecting surface, the photoelectric spherical object detection counter of the present invention has a configuration of detecting the object spherical object by blocking optical coupling. However, it is completely unaffected by variations in surface reflectance due to discoloration, damage, marking, etc. on the outer surface of the test object. Further, since the photoelectric sphere detection counter of the present invention can increase the installation interval between the light emitting element and the light receiving element, malfunction due to noise such as scattered light can be avoided. Also, when blocking the optical coupling path of the test object, it is a mechanism that counts the test object,
When the sphere to be inspected interrupts the optical coupling path, it disturbs the disturbance, so the influence of the disturbance is minimized.When the optical coupling path is connected, even if there is ambient light, the sphere of the object to be inspected is counted. Since there is no influence, can improve the detection accuracy and prevent malfunction.

Further, the photoelectric spherical object detection counter according to the present invention is one in which a light emitting element and a light receiving element are arranged so as to form a reflected light coupling path via a reflecting portion provided on the opposite side, The light emitting element and the light receiving element can be arranged compactly, and in some cases, both can be combined as an integral assembly. Further, in the photoelectric spherical object detection counter according to the present invention, the reflected light coupling path formed between the light emitting element and the light receiving element is set to be about twice or more the diameter of the object spherical object, and As shown in FIG. 3, the space between the contacting object spheres, which is surely formed on both sides of the contact, is focused, and one of the reflected light coupling paths ( Since LR 1 ) is set so that the other side (LR 2 ) of the reflected light coupling path passes through to the other space, it should be a photoelectric type spherical object detection counter with high reliability without malfunction.
