When the communication portion receives an interlock command transmitted from an electric working machine, the interlock operation control portion makes the dust collection portion operate interlocking with the electric working machine. The interlock operation control portion includes a storage portion, in which identification information specific to the electric working machine with which the dust collection portion is to be made to perform the interlock operation is stored. ## Claims ### Claim 1 A dust collector comprising: a dust collector main body configured to operate by receiving a power supply from an external alternating current power source; and a communication unit (1) attached to the dust collector main body, (2) configured to receive an interlock command wirelessly transmitted from an electric working machine and to output an operation command to the dust collector main body in response to receipt of the interlock command, and (3) including a circuit board having a first end and a second end, the first end being provided with an antenna for wireless communication, and the second end being provided with a signal input/output portion configured to input and output a signal including the operation command to and from the dust collector main body. ### Claim 2 (depends on 1) The dust collector according to claim 1, wherein: the dust collector main body includes an isolation device configured to electrically isolate the alternating current power source from the communication unit; and the isolation device includes an isolation transformer. ### Claim 3 (depends on 1) The dust collector according to claim 1, wherein: the dust collector main body includes an isolation device configured to electrically isolate the alternating current power source from the communication unit; and the isolation device includes a contactless circuit configured to contactlessly transmit a signal between an operation portion and the communication unit, the operation portion being configured to operate by receiving a power supply from the alternating current power source. ### Claim 4 (depends on 1) The dust collector according to claim 1, wherein the communication unit further includes a communication control portion configured to control a signal inputted and outputted via the antenna and the signal input/output portion. ### Claim 5 (depends on 1) The dust collector according to claim 1, wherein the dust collector main body includes: a power supply path configured to supply an electric power to the communication unit; and a detection circuit configured to detect, based on an electric current flowing to the power supply path, that the communication unit is attached. ### Claim 6 (depends on 4) The dust collector according to claim 4, wherein the communication unit further includes a case, and wherein at least the communication control portion is covered by a waterproof resin member and housed inside the case. ### Claim 7 (depends on 1) The dust collector according to claim 1, wherein the first end of the circuit board is located opposite to the second end of the circuit board. ### Claim 8 A dust collector comprising: a dust collector main body configured to operate by receiving a power supply from an external alternating current power source; and a communication unit (1) attached to the dust collector main body and (2) configured to receive an interlock command wirelessly transmitted from an electric working machine and output an operation command to the dust collector main body in response to receipt of the interlock command; wherein: the dust collector main body includes an isolation device configured to electrically isolate the alternating current power source from the communication unit; and the isolation device includes a contactless circuit configured to contactlessly transmit a signal between an operation portion and the communication unit, the operation portion being configured to operate by receiving a power supply from the alternating current power source. ### Claim 9 A dust collector comprising: a dust collector main body configured to operate by receiving a power supply from an external alternating current power source; a power plug connected to the dust collector main body, the power plug being configured to receive an alternating-current power from the external alternating current power source; a communication unit (1) attached to the dust collector main body and (2) configured to receive an interlock command wirelessly transmitted from an electric working machine and output an operation command to the dust collector main body in response to receipt of the interlock command; and a changeover switch (1) provided in the dust collector main body, (2) electrically coupled to the power plug, and (3) configured to be changed into a first state, a second state, and a third state; wherein the changeover switch in the first state makes the dust collector main body operate interlocking with an operation of the electric working machine, the changeover switch in the second state inhibits the dust collector main body from an interlock operation with the operation of the electric working machine, and the changeover switch in the third state stops an operation of the dust collector main body.
