OUTPUT SYSTEM AND FOOT SWITCH

PROBLEM TO BE SOLVED: To provide an output system which can exactly perform a wireless communication and has a foot switch capable of reducing power consumption. SOLUTION: In the output system 12, the foot switch 14 comprises: foot switch side transmission means 46a and 50a which transmit an output signal; and a signal intensity adjustment means 54 for adjusting the signal intensity of the output signal transmitted from the foot switch side transmission means 46a and 50a. An apparatus body 20 comprises: body side transmission means 46b and 50b for receiving the output signal transmitted from the foot switch side transmission means 46a and 50a; and a receiving situation detection means 56 for detecting the receiving situation of the body side transmission means 46b and 50b. The receiving situation is transmitted from the main body side transmission means 46b and 50b to the foot switch side transmission means 46a and 50a, and the signal intensity adjustment means 54 adjusts the signal intensity according to the receiving situation.
