PORTABLE AND RECHARGEABLE AUTOMATIC LENSMETER

摘要

PURPOSE: A portable and rechargeable automatic lensmeter is provided to reduce power consumption and to allow a user to carry the portable and rechargeable automatic lensmeter easily by preventing high AC voltage from flowing into the lensmeter. CONSTITUTION: A portable and rechargeable automatic lensmeter includes a fixing/moving unit(10) for fixing/moving a position of a lens to be measured. Optical characteristics of the measured lens are detected by an optical system(12). A hardware section(50) has an interface(20) of users display device(25), a calculator(40) and a recharge battery(30). The display device(25) includes a touch screen type LCD monitor. The interface(20) of users includes a one-touch type interface accommodated in the touch screen type LCD monitor. The calculator(40) is operated by receiving low DC voltage from the recharge battery(30) so as to control the interface(20) of users. The calculator(40) outputs a measuring value of the measured lens by receiving a digital image signal from the optical system(12).
