a driven roller 33 and a conveying belt 34 which runs along the bottom faces of the eight containers 1 and around the rollers 32 and 33 for conveying packages a to the discharge port the belt 34 has on its outer surface projections 35 arranged at intervals of a pitch which is a little larger than the diameter of the package a provided above the driving roller 32 and the driven roller 33 of the conveyor system 31 are a light emitting element 36 and a light receiving element 37 respectively in a face to face alignment the elements 36 and 37 are adapted in cooperation with each other to detect whether there is any package a carried on the belt 34 or not and to stop discharging operation of the machine when no package on the belt is detected provided above the left hand portion of the conveyor system 31 i e the left hand portion of the belt 34 wherefrom packages of coins a are to be sent out of the machine is a counting device generally indicated by reference numeral 38 for counting the number of the packages a which are sent to the discharge port the counting device 38 comprises a generally star shaped detection plate 39 mounted for rotation about a shaft 40 the plate 39 is so disposed that it is rotated a predetermined angle by every package a passing there mounted also to the shaft 40 is a disk 42 which has concentric ratchets 43 and 44 secured on the opposite sides thereof for preventing the detection plate 39 from free or unrestrained clockwise and counterclockwise rotations such rotation of the disc 42 is detected by a sensor.
