  We present the observational results of this kind of rare object 1SWASP
J093010.78+533859.5, for which the doubly eclips- ing feature had been detected
previously from the SuperWASP photometric archive. Individual PSF photometry
for two objects with a separation of about 1.9 arcsec was performed for the
first time in this study. Our time-series photometric data confirms the finding
of Lohr et al. (2013) that the bright object A is an Algol-type detached
eclipsing binary and the fainter B is a W UMa-type contact eclipsing. Using the
high- resolution optical spectra, we obtained well-defined radial velocity
variations of system A. Furthermore, stationary spectral lines were detected
that must have originated from a further, previously unrecognized stellar
component. It was confirmed by the third object contribution from the light
curve analysis. No spectral feature of the system B was detected, probably due
to motion blur by long exposure time. We obtained the binary parameters and the
absolute dimensions of the systems A and B from light curve synthesis with and
without radial velocities, respectively. The primary and secondary components
of system A have a spectral type of K1 and K5 main sequences, respec- tively.
Two components of system B have nearly the same type of K3 main sequence. Light
variations for both binaries are satisfactorily modeled by using two-spot
models with one starspot on each component. We estimated the distances to
systems A and B individually. Two systems may have similar distances of about
70 pc and seem to be gravitationally bound with a separation of about 130 AU.
In conclusion, we suggest that 1SWASP J093010.78+533859.5 is a quintuple
stellar system with a hierarchical structure of a triple system A(ab)c and a
binary system B(ab).
