A projector including a computer has: an internal storage device that stores therein a basic system, which is executed first by the computer on actuation of the projector (S110), and a first control system that is activated through processing of the basic system to control operations of the projector, and a memory controller that reads information stored in a mobile memory (S130). On actuation of the projector (S110), the basic system reads information stored in a specific area of the mobile memory (S130) attached to the memory controller prior to activation of the first control system, identifies whether or not the information in the specific area is a specific piece of information (S140), and, when the information in the specific area is identified as the specific piece of information, activates a second control system stored in the mobile memory, in place of the first control system (S180). This arrangement enables the projector to utilize a new operating system. <IMAGE> |
