摘要： A camera system includes a camera having a focal plane shutter and an electronic flash device cooperable with the camera. The flash device, which emits light repetitively, has two operating modes. In a first mode, a light emission start signal is synchronized with the start of the exposure of a film exposure area by a leading curtain of the shutter, and a light emission stop signal is synchronized with the end of the exposure of the film exposure area by a trailing curtain of the shutter. In a second mode, the light emission start signal is synchronized with the full exposure of the film exposure area by the leading curtain, and the light emission stop signal is synchronized with the start of shielding of the film exposure area by the trailing curtain.

摘要： A switching power source device provides a desired AC/DC output by producing a pulse width-modulated waveform through ON-OFF control of a pair or pairs of switching elements connected in series with an input power source, eliminating high-frequency components of the pulse width-modulated waveform with a smoothing choke. The switching power source device is configured so that the input power source will not be short-circuited and consequently suffer a voltage and/or current surge, even when both switching elements in the pair assume the ON status at the same time by dividing the smoothing choke into two portions. The two portions of the smoothing choke are connected in series with the input power source when the switching elements in the pair assume the ON status at the same time.

摘要： A small-size copying machine has an image sensor and a print head for printing image information or visible data on copying paper. The copying machine is moved over an original document to read the visible data with the image sensor, and the visible data read by the image sensor is printed by the print head on the copying paper. The reading of the visible data with the image sensor is synchronized with the printing of the visible data onto the copying paper with the print head by fixing an end of the copying paper discharged from the copying machine and moving the copying machine with respect to the original document. The distance from the position where the visible data of the original document is read to an outlet slit for discharging the copying paper therethrough is equal to the distance from the position where the visible data is printed by the print head on the copying machine to the outlet slit, so that the data printed on the copying paper and the image of the original document will be overlapped. The copying machine may have a tapered body portion with a reading slit defined therein for facilitating the reading of the original document with the copying machine. The copying machine may have an inclined bottom panel for allowing the copying machine to be moved easily over the original document. The copying machine may also have on sides thereof markings for indicating a width and a position where the original document is to be copied.
