US 6,640,056 B2 · Camera for driving lens unit removably attached thereto and method for controlling drive therebetween

Abstract

A photographing apparatus suitable for fixing an optical unit thereto, and a method for controlling a device in the unit from the apparatus. The apparatus includes: a unit fixing portion for fixing the unit thereto; a driver which runs the device in the unit; a controller which controls the driver and includes a primary controller; and a detector which finds running properties of the driver. The primary controller makes the driver work before an aimed running so as to run the device in the unit up to a set amount in a set timing, and makes the detector find running properties of the driver at the same time. During the aimed running, the controller makes the driver work, referencing to running properties found by the detector.
