Abstract: A projection device comprises an input section for inputting an image signal, a storage section for storing the image signal input by the input section after adding identification information thereto, a projection section for forming and projecting an optical image corresponding to the image signal, and a projection control section for using an image signal currently input by the input section and the image signal already stored in the storage section to cause the projection section to project, as one image, a plurality of screens together with indications based on the identification information for the respective screens.

Abstract: A controller controls exchange of data between a plurality of storage units based on transfer rates of the storage units and a fixed rate. If at least one of the transfer rates of a transfer-source storage unit and a transfer-destination storage unit are different than the fixed rate, the controller accumulates a certain amount of data, and outputs accumulated data to the transfer-destination storage unit at the transfer rate of the transfer-destination storage unit so that data is transferred from the transfer-source storage unit to the transfer-destination storage unit at apparently at the fixed rate.

Abstract: In a detection element for the current which flows from a power source to a disk apparatus internal circuit, a plurality of resistors are incorporated such that the detection resistance for consumption current can be selected. Based on apparatus identification information from an apparatus identification unit 31 such as a current identification signal outputting circuit or an apparatus identification structure provided in a disk apparatus unit, the detection element switching circuit switches the detection resistance value of the detection element. A voltage detection circuit detects the potential difference between both terminals of the detection element. When a current control circuit detects an excessive current based on the potential difference, the current control circuit turns off a transistor (FET).
