PROBLEM TO BE SOLVED: To provide a system wherein scale of a circuit of a sensor system is made small and changing in operation is facilitated and wirings are made less and furthermore, load of a control device is reduced. SOLUTION: Optical sensors 21 and 22 are connected with a processing device 25 through an integration-comparison parts 23 and 24. Processing devices 29, 34 and 38 are respectively connected with a tray detecting sensor 11, a microswitch 32 and a proximity switch 36. The processing devices are constituted of microcomputors and are connected with a communication medium 40 through network interfaces 26, 30, 35 and 39. Operations in the processing devices 25, 29, 34 and 38 are changable by changing programs by means of a control device 17. |
