Title: Auxiliary optical device for focal point detecting device
Inventor: ONUKI ICHIRO
IPC: G03B3/00
Filed: 1987-12-29
Abstract: PURPOSE:To bring a focal point detecting area into a satisfactorily lighted state by varying an auxiliary light illuminating range according to information on the focal length of a photographing lens, information on the position and size of the tip of a lens barrel, information on a minimum photographing length or information regarding the position of a focusing lens. CONSTITUTION:By turning on a focal point detection start button, a camera CPU 21 and a lens CPU 28 start communicating: the lens CPU 28 reads out lens inherent information out of its built-in memory, or reads said information from encoders 30 and 31, and transmits it to the camera CPU 21. Prior to focal point detection, the camera CPU 21 measures the brightness of an object, and if the brightness is low, the camera CPU 21 sends focal length information to a stroboscope CPU 24, and instructs a zooming optical system 26 to zoom and to change the illuminating angle of auxiliary light in response to the focal length. At the end of zooming, the stroboscope CPU 24 causes an auxiliary light source 16 to emit light, and simultaneously the camera CPU 21 calculates defocus quantity. Thus, the focal point detecting area can be lighted appropriately and constantly.

A commercial electric current at 50 or 60Hz frequency is energized through the tinplate to heat the tinplate in this reflowing, and the waveform of the AC current is made rectangular. When the current applying time is denoted by t1 and the current stopping time by t2, t1/(t1+t2)=0.75-0.95 is satisfied, hence the generation of wood patterns on the tinplate surface is prevented, and the damage of the appearance is obviated.
