Abstract: A rinsing device is comprised of a rinsing head including a first flow path extending horizontally, and a second flow path extending horizontally and being disposed below or above the first flow path so as not to communicate with the first flow path; one or more nozzles arranged horizontally and projecting vertically downward from the rinsing head; and one or more sliding members including passages in fluid communication with the nozzles, the sliding members slidably fitting in the rinsing head and being movable between a first position to place the passages in fluid communication with the first flow path and a second position to place the passages in fluid communication with the second flow path.

Abstract: A device for dispensing directional objects is comprised of: a case for housing the objects in a horizontal direction; a shutter covering the case and capable of leaving a window; a pivot pivotally supporting the case to allow the case to swing around the pivot; a conveyor including a plurality of slots respectively holding the objects in the horizontal direction and being disposed to receive the objects dropped through the window into the slots; a guide including a bottom end and a slit opened upward to receive the objects dropped from the conveyor and gravitationally feed the objects toward the bottom; and a dropper coupled with the bottom end of the guide, where the objects are dispensed with the tip ends thereof directed downward.
