<p>PROBLEM TO BE SOLVED: To provide a finder device that can surely prevent a backlash in a state where an eyepiece lens unit is mounted in finder devices allowing the eyepiece lens unit to be detachably attached to a device body without increasing the number of components.SOLUTION: A finder device is configured to prevent a backlash upon attachment of an eyepiece lens unit to a device body by an elastic member that applies a given operational force to a diopter adjustment unit moving an eyepiece lens to an optical axis direction to thereby conduct diopter adjustments. Accordingly, it is unnecessary to provide a component exclusive for backlash prevention, which in turn enables reduction in the number of components.</p> |
