Displacement mechanism control device in a camera |
摘要 |
A camera displacement mechanism control device can maintain the time required to effect removal of backlash within a set time. Zooming-down is started by the zoom-down switch being turned ON, and the lens barrel is driven as far as the wide-angle terminus if the zoom-down switch is not turned OFF during zooming-down. Alternatively, if the zoom down switch is turned OFF during zooming-down, the lens barrel is driven to the next halt position after the position where the zoom-down switch was turned OFF. In either case, the lens barrel is caused to overshoot the target halt position in the direction of scrolling-in for a time interval long enough to effect removal of backlash, and is subsequently driven in the direction of scrolling-out and halted at the described target halt position.
