发明名称 VIBRATION PROOFING DEVICE
摘要 <p>PURPOSE: To make an objective lens mechanism compact and to save electric power when a correction means is driven by providing a vibration proofing device with the correction means relatively rotated with respect to an equipment in which the device is loaded or a lens barrel holding an objective lens. CONSTITUTION: The signals of vibration detection means 91p and 91y and the signal of a photointerruptor 15 are inputted to a target value arithmetic means 11. Based on the rotating angle signalθof the photointerruptor 15, a new target value for correcting the deflection of the correction means (lens barrel 710) is calculated. That means, even when a deflection correcting direction is changed because the lens barrel 710 is rotated, the deflection is corrected by mutually calculating the target value of the deflection correcting direction and obtaining the new target value so as to cancel the change. Then, vibration proofing accuracy is prevented from being deteriorated caused by the rotation of the lens barrel 710. By providing the vibration proofing device with the correction means and the target value arithmetic means in such a way, the deterioration of the vibration proofing accuracy is eliminated and a focus mechanism and a zoom mechanism are made compact.</p>
