An instruction executing part 12 carries out a serializing instruction after the end of the delay to read a 1st area set in its own system and at the same time write the prescribed data. Then the part 12 reads a 2nd area set at another system to decide the data writing state of another system and then reads and decides repetitively the 2nd area as long as no data is written into this area. A detecting part 13 monitors the executing state of another system and decides an error if the another system continues a deciding action even after a prescribed time to report the error.

Title: Sorter for discoid article
Inventor: RUDORUFU SHIYUTETSUKURI
IPC: B65G47/78
Filed: 1988-06-03
Abstract: Coins (24) lying on a turntable (22) driven in the direction of rotation (20) are forced by centrifugal force into a discharge channel (30) whose height limits the permissible thickness of the coins. Coins fed from the discharge channel (30) are rolled off with an S-shaped movement at a roll-off lip (38) when picked up by a conveyor belt (40) acting from above and are then conveyed away in a straight direction (42). The S-shaped movement is impressed on the coins (24c) by the arrangement of components (36, 38) which limit an exit opening (28) and which also include the roll-off lip (38). Such an arrangement ensures a reliable and trouble-free separation with few moving parts.
