A component supplying apparatus which is appended to the electronic component working apparatus, for supplying electronic components to the electronic component working apparatus is provided. The component supplying apparatus includes a component storing section which stores the electronic components, and movement range regulator. The movement range regulator allows the component storing section to move between a supply position P1 which is set for supplying the electronic components and a retracted position P2 to which the component storing section is retracted for the purpose of maintenance of the electronic component working apparatus. In addition, the movement range regulator regulates the range of relative movement of the component storing section with respect to the electronic component working apparatus to a movement amount L4 that is previously established.
