Patent ID: 8032253

Claim:
An automatic machine system comprising: a mechanism unit including at least one driving mechanism; a controller for controlling a driving operation of the mechanism unit; and a teaching unit for operating the mechanism unit, wherein the teaching unit includes: a teaching unit communicating portion for carrying out a wireless communication with the controller; and a first field intensity monitoring portion for monitoring a field intensity of communication data in the teaching unit communicating portion, and the controller includes: a controller communicating portion for carrying out a wireless communication with the teaching unit; a second field intensity monitoring portion for monitoring the field intensity of communication data in the controller communicating portion; and a driving portion for driving the mechanism unit based on an operation signal sent from the teaching unit, which is received in the controller communicating portion wherein the first or second field intensity monitoring portion gives an alarm to an operator when the field intensity is equal to or smaller than a first threshold which is preset, and stops the driving operation of the mechanism unit when the field intensity is equal to or smaller than a second threshold which is preset wherein the first or second field intensity monitoring portion releases a radio channel used in the wireless communication when the driving operation of the mechanism unit is stopped.
