The paper supply mechanisms 2a, 2b are provided with size detection means 15a, 15b for detecting the size of the cassette paper and with paper absence detection means for detecting whether there is cassette paper or not. Detection information from these detection means is applied to a control circuit 21. When the cassette paper of size in a desired paper supply cassette under paper supply has run out, the cassette paper of the same size in another paper supply cassette is detected for switching. Information on the switching is entered into a paper supply switching means 12 to perform the switching to successively supply the paper from the cassette of the same size.
