Abstract: PURPOSE: To enable the feeding of large size paper, by means of a plurality of paper holders, a carry roller provided in advancing direction, and a paper detector provided in front of said carry roller such that the distance from the center of carry roller is shorter than the interval of holder.  
     CONSTITUTION: The end of first manuscript 6a is mounted on the magnet 5a of first holder 5-1, then the stopper board 5c is felled down to hold it. Required number of papers are set in similar manner. Upon starting it is carried by carry roll 7 associated with paper 6a and pinch roll 9 while when its leading edge is detected by detector 10 motor 1 is stopped. Since the distance L2 between the detector 10 and the center of carry roll 7 is shorter than the interval L1 of holder, second paper 6b isn't catched by carry roll 7. The paper 6a is pulled out from holder 5-1 and further carried, and when the trailing edge is passed through the detector 10 the motor 1 is driven again to process second paper 6b.

Abstract: PROBLEM TO BE SOLVED: To provide an optical recording medium having double density, based on information from two sheets of CD-Rs by separating the entire data into the first half/second halves, providing an intermediate area to connect the both and correcting a data format of a Q channel code. SOLUTION: A phase pit line which is to become the data is separated into three areas of a first half data area 8, the intermediate area 9 and a second half data area 10. Respective areas 8, 9 and 10 are successively arranged in a read-in 11, the area 8 and the area 9. By making one among the eight bits existing in a ZERO item in the Q-channel code in the read-in 11 a bit 1, the fact that the optical recording medium is of double-density can be recognized. The area 9 functions as a link area at the time of switching from a first sheet to a second sheet. At this time, the original data before EFM modulation conversion, except the Q channel of the area 9, are all zero. Further, by making the Q-channel of the area 9 the same as the final frame of the area 8, advance of a reproducing time is stopped in the reproduction of the area 9.
