Claims

[Scope of utility model registration request]

In a capacitor type cartridge device having a plurality of fixed electrode plates provided substantially orthogonally to the pace mold of the cartridge, a notch is provided in one or both of opposing sides of the plurality of fixed electrode plates; A capacitor type cartridge device characterized in that both rotating constant electrode plates are assembled in a notch so as to be substantially perpendicular to each other in a non-contact state.
