Abstract
An electronic photo-copying apparatus in accordance with the present invention comprises: at least one paper feed device comprising a paper feed cassette rotatably supported so as to move in the feeding direction thereof interchangeably between the longitudinal and lateral directions and a driving device for rotating the paper feed unit; and, a control device for controlling the paper feed device so as to permit it to switch the feeding direction of copy paper interchangeably between the longitudinal and lateral feeding directions by rotating the paper feed device by the driving device regardless of operation conditions of an electronic photo-copying apparatus main body. With the above arrangement, since the paper feed cassette can be rotated in the direction interchangeably between the longitudinal and lateral directions even when the electronic photo-copying apparatus main body is in operation, waiting time can be eliminated which is required for switching the feeding directions of copy paper stored in the paper feed cassette, and therefore working efficiency can be improved.
