To improve safety and to prevent gear deformation, etc., by making a driving source non-drivable in the state that a hair removing head block and a main body casing are removed from each other in beauty equipment obtained by freely attachably and detachably providing the hair removing head such as a hair removing head, a cutting head at the main body casing which can be grasped by a hand.

In the state that a hair removing head block is correctly mounted to a main body casing, the upper end part of an insulated board 81 is pushed by the lower end face part of a block to be lowered against a pushing up spring 82 to bring a contact spring 80 in contact with a contact part provided at a switch print wiring board 83. Consequently, at the time of turning on a switch 15, a motor is driven to execute hair removing processing. On the other hand, in the state that the hair removing head block is removed from the main body casing, the board 81 is pushed up by the spring 82 and the spring 80 and the contact part provided at the board 83 are brought into non-contact with each other through the board 81. Consequently, in spite of turning on the switch 15, the motor is not energized and the equipment is kept in an inactive state.
