PAPER FEEDING MECHANISM FOR ROLLED TYPE RECORDING PAPER

摘要

PURPOSE:To facilitate setting of recording paper and simplify construction by detecting the displacement of a turning plate in a paper feeding passage and interlocking an opening/closing cover with the turning plate so as to release the contact with a roll when the cover is set in the opening direction and to contact with the roll when the cover is set in the closing direction. CONSTITUTION:When an angle detector 12 detects the exhaustion of the amount of recording paper 1, and an opening/closing cover 8 is opened by turning it in the C direction, also a plate 3 is turned in the A' direction in linkage, and new recording paper 1 can be easily set into a holder. Then, the recording paper 1 is introduced into a printing and cutting mechanism, and when the cover 8 is closed by turning it in the C' direction, also the plate 3 turns in the A direction in synchronization, and contacts with the roll part 1a of the recording paper 1. At this time, the projection 13a of the link is positioned under an elliptical hole 15a, and when the diameter of the roll part 1a reduced through the consumption of the recording paper 1, the plate 3 and the link 13 turn in the A direction, and the projection 13a rises in the elliptical hole, but the projection is engaged so as not to reach the upper edge even if the diameter reduces to the min. Thus, setting of recording paper is facilitated and the construction can be made simple.
