Electron and proton energy spectra gained at acceleration by a super-Dricer electric field are investigated in the non-neutral reconnecting current sheet (RCS) with a non-zero longitudinal component of magnetic field (a guiding field) directed along the electric field. The other transverse and tangential magnetic component are considered varying with the distances from the X null-point. The proton and electron energy spectra are calculated numerically from a motion equation using the particle-in-cell approach for the model RCSs with constant and variable densities. In the presence of a strong or moderate guiding field protons were found fully or partially separated from electrons at ejection from a RCS into the opposite semiplanes, 'electron' and 'proton' ones while for a weak guiding field they are ejected symmetrically as neutral beams. The particles ejected from a RCS with a very strong guiding field have the power-law energy spectra with spectral indices about 1.5 for protons and 2.0 for electrons. For a moderate guiding field the electron and proton spectra are a combination of power law and thermal-like ones.
