A paper feeding device, used in a copier, has a swivel cassette capable of turning to a longitudinal feed position for longitudinal paper feed and to a lateral feed position for lateral paper feed. The paper feeding device is so arranged that the swivel cassette is automatically turned to a priority-given position when power is turned on, auto clear is executed or an all clear key is depressed. The paper feeding device has a memory for storing the number of sheets supplied from a respective one of the feed positions of the swivel cassette. A paper feed position used high frequency is regarded as the priority-given position by comparing the stored numbers with each other, so that the swivel cassette is set to the paper feed position used high frequency when power is turned on, auto clear is executed or the all clear key is depressed. Accordingly, the user can save the trouble of changing over to that feed position used with high frequency, and this feature improves the convenience of the copier.
