Abstract
PURPOSE: To make it possible to stably photograph the data even when the electric power is used for either data photographing or stroboscope in common by stopping the oscillation of booster oscillation circuit of stroboscope circuit during the operation of data photographing circuit.
CONSTITUTION: Oscillation of booster transformer circuit is weakened from the suitable period prior to the data photographing. During the data photographing the collector potential of Tr4 is lowered, which shows the signal for detecting the operation of data photographing. Hence the base of transistor Tr2 is lowered by the collector of Tr4 via resistor R4 to suspend the operation of the booster oscillation circuit. Thus the data photographing circuit C obtains a stable energization of electric power. As soon as data photographing ends Tr4 is made OFF so that the oscillation circuit reopens its oscillation ready for the next use
