| 摘要 |
The invention relates to a device for driving a fastening element into a substratum, said device comprising a mechanical energy store for storing mechanical energy, an energy transfer apparatus for transferring energy from an electrical energy source to the mechanical energy store, and an electronic control apparatus, which is supplied with electrical energy by the electrical energy source and is suitable for initiating an energy withdrawal process when the supply of energy to the control apparatus by the electrical energy source is interrupted. In the energy withdrawal process, energy possibly stored in the mechanical energy store is converted into electrical energy and fed to the control apparatus in order to supply the control apparatus. |
