发明名称 STROBOSCOPE USAGE CONTROLLER
摘要 PURPOSE:To prevent the deterioration and the damage of a heat generating element by inhibiting a stroboscope from being used from a time when the temperature of a heat generating element rises because of a continuous stroboscope photographing and the temperature reaches to near an allowable value till the time when it returns to an initial temperature. CONSTITUTION:In case of the continuous stroboscope photographing, a charging for stroboscope is inhibited by a detection that the charging for the stroboscope of the prescribed times have done till the time required for the heat radiation has passed; then the deterioration and the damage of the heat generation element of a transformer for an oscillation, etc., are prevented. That is, when a stroboscope circuit (b) is continuously used, a timer circuit (c) is reset, starts again an initial clocking action, and also outputs a count signal to a counter circuit (d). A counted content at the counter circuit (d) is compared with a reference data held in a reference data holding circuit (f) by means of a discriminating circuit (e); then the detection of the coincidence between them makes the signal for inhibiting a stroboscope usage be outputted to a controlling circuit (a), and a timer circuit 5 is reset.
