Filed: 1994-06-10
Abstract: PURPOSE:To improve processing function of a printer by recording information in a film in the case when exposure is carried out properly for standard light exposure printing for all frames of a roll of film used for photographing. CONSTITUTION:CPU 1 lowers Fft flag of the information regarding a standard light exposure printing to zero at the time of AE mode and AE is NG in the case a strobe 14 is in OFF state. The CPU 1 lowers the Fft flag to zero at the time of automatic strobe mode and light modulation NG in the case the strobe 14 is in ON state. In all other cases, the Fft is kept 1.

Title: Power interruption detector for voltage resonance type power source
Inventor: SHIOTANI MASAKI
IPC: H02M3/28
Filed: 1991-06-24
Abstract: PURPOSE:To miniaturize a power source by detecting an input voltage at a secondary side of a transformer and utilizing it as a power interruption detection signal. CONSTITUTION:A switching frequency detector 30 inputs a switching signal present at a secondary winding Ns1, and generates, for example, a voltage signal Vfs proportional to a switching frequency fs by using a counter. A power interruption discriminator 32 compares the signal Vfs with a reference voltage Vref2, and outputs a power interruption detection signal PF when the frequency fs corresponds to a state of a reference switching frequency or less. When a load current is detected and the reference switching frequency is delicately regulated, the power interruption signal is output at more accurate timing. Thus, the signal PF can be obtained by a simpler constitution than that of prior art. Since a primary side is insulated from a secondary side, a power source can be miniaturized.
