摘要： The present invention provides a projection apparatus utilizing plural light sources, in which the light source principally irradiating the light valve is switched by moving the relative position between the plural light sources and the mirror for guiding the lights outputted from such light source to the light valve. Also the configuration can be simplified by using commonly the light condensing device for the plural light sources.

摘要： The present invention is directed to a reproducing apparatus for reproducing a composite signal from a record bearing medium on which said composite signal is recorded, said composite signal being formed by frequency multiplexing a frequency-modulated luminance signal and a low-band converted carrier chrominance signal which is obtained by frequency-converting a carrier chrominance signal from a high frequency band to a low frequency band. The recording apparatus is constructed to separate the frequency-modulated luminance signal and the low-band converted carrier chrominance signal from the composite signal reproduced from said record bearing medium, to demodulate the frequency-modulated luminance signal to restore the luminance signal, to convert the low-band converted carrier chrominance signal into two kinds of color difference signals and to form R, G and B signals from the luminance signal and the two kinds of color-difference signals thus obtained. According to this construction, it is possible to form and output the R, G and B signals, without causing deterioration of signals.
