Claim 4:
5. A periphery monitoring system for a work machine, comprising:
a machine body;
a front work device that is provided in the machine body; and
an operation device that outputs an operation signal for operating the machine body and the front work device, wherein
a sensor that detects an object around the machine body, and
a controller that has a control function for controlling operation of the machine body or the front work device when receiving a detection signal from the sensor are included,
the controller determines whether or not the control function is enabled and whether or not the operation device is operated when receiving the detection signal,
when it is determined that the control function is disabled or when it is determined that the control function is enabled and the operation device is operated, a command for issuing a first state warning is transmitted, and
when it is determined that the control function is enabled and it is determined that the operation device is not operated, a command for issuing a second state warning that is weaker in warning intensity than the first state warning is transmitted.
