- Representative inspection items performed at the production site of the imaging apparatus may include sound adjustment, image quality adjustment, and mode switching, and may include various inspection items. If these inspection items are collected into similar items and a single inspector performs the inspection while operating the remote controller, the inspection efficiency can be improved to some extent depending on the skill of the operator. It does not lead to the improvement of productivity and the fall of the defective rate. According to this embodiment, these inspection items are further subdivided (e.g., subdividing the sound adjustment into amplification and reduction), so that a plurality of workers are arranged in a row to continue the work assigned to the worker. As a result, it is possible to obtain an improvement in work speed and work accuracy expected by the operator.
