Filed: 1995-06-02
Abstract: PURPOSE: To provide a camera mechanism capable of effectively covering a gap caused by the eccentricity of a camera lens barrel and a camera case which can not be prevented in assembling accuracy, even if the gap is generated. CONSTITUTION: An annular decorative ring 42 and a guiding ring 44 are screwed into the gap generated by a moving lens barrel 26 and the through-hole 38 of the front cover 40, to hold it The camera mechanism is designed to make the outside diameter of the base part 44a of the guiding ring 44 smaller than the inside diameter of the through-hole 38 of the front cover 40 and structured so that the gap S11 caused by the difference between the inside and outside diameters is a maximum span for allowing a positional deviation caused by the eccentricity of the front cover 40 and covered with the base part, 42a of the decorative ring 42, not to be seen outside.  Velveteen 42c is stuck to the inside of the projected line part 42b of the decorative ring 42 and the very small gap between the decorative ring 42 and the moving lens barrel 26 is shielded to prevent external light, dust, etc., from entering.

IPC: H02M3/155
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To reduce power loss by an output voltage detection means and at the same time miniaturize circuit components. SOLUTION: A-boosting chopper device has a main circuit 3 that includes a boosting inductor and a switching means in series and a smoothing means 4 that is connected between both terminals of a switching means 3b, and switches the switching means 3b by a control means 5.
