We designed and developed a multi-purpose CCD camera system for three kinds of CCDs; KAF-0401E(768$\times$512), KAF-1602E(1536$\times$1024), KAF-3200E(2184$\times$1472) made by KODAK Co.. The system supports fast USB port as well as parallel port for data I/O and control signal. The packing is based on two stage circuit boards for size reduction and contains built-in filter wheel. Basic hardware components include clock pattern circuit, A/D conversion circuit, CCD data flow control circuit, and CCD temperature control unit. The CCD temperature can be controlled with accuracy of approximately $0.4^\circ$C in the max. range of temperature, $\Delta 33^\circ$C. This CCD camera system has with readout noise 6 e$^{-}$, and system gain 5 e$^{-}$/ADU. A total of 10 CCD camera systems were produced and our tests show that all of them show passable performance.
