Title: Record paper feeder
Inventor: TAKAGI YOSHIAKI
IPC: B65H18/26
Filed: 1982-07-26
Abstract: PURPOSE:To feed out record paper without zigzag while to facilitate mounting of a record paper roll, by contacting a drive roller continuously against the circumferential face of a record paper roll thereby rotating the record paper roll directly through the drive motor. CONSTITUTION:Upon turning-on of an electromagnetic clutch 19, the rotary force of a motor 18 is transmitted through said clutch 19 and a chain 21 to a drive roller 13. Consequently the drive roller 13 will rotate to rotate a record paper roll 10 pressure contacting against said roller 13 directly thus to feed a record paper 10b to the next process. When desired length of record paper 10b has been fed out, an electromagnetic brake 12 is functioned while simultaneously said clutch 19 is turned off to stop the drive roller 13 and the record paper roll 10. As the diameter of the record paper roll 10 reduces, the drive roller 13 guided by an elongated hole 11c and follows in the direction of the central axis of the record paper roll 10 through a spring mechanism 14.
