Title: Thermal printer
Inventor: OMINE TSUTOMU
IPC: B41J15/16
Filed: 1988-02-26
Abstract: PURPOSE:To enable printing almost free from color shift by moving paper while helding it using a paper holding roller, spreading the paper between the paper holding rollers and winding it on a platen without generation of any slack. CONSTITUTION:As soon as paper 1 is fed, a motor 13 rotates rollers 11, 12, and the paper 1 is fed into between the rollers, on a guide plate 9 and a platen 6 and then between the rollers 12. If the start end of the paper is detected by a sensor 80, the motor 13 stops and the paper 1 also comes to a standstill. Both ends of the rollers 11, 12 are held while the paper is wound around the platen 6. In the meantime, ink film 2 is fed to allow the cueing of the first color while the paper is loaded, and a thermal head descends to press the ink film 2 and the paper 1 against the platen 6. If a reversible motor 22 is started, a heat-generating element on the thermal head 3 is driven, while the ink film 2 is moved to the winding roller 8 side simultaneously. Consequently, the first- color printing is performed on a desired place on the paper 1. In the same way, the second, third and fourth colors are printed.

Title: Squeeze method for printing device
Inventor: OKUTSU KOICHI
IPC: G03F7/20
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To make a squeeze time shorter when an image is printed on a printing plate of the size of four or two pages of newspaper. SOLUTION: One end side of a printing plate 14B in the longitudinal direction thereof is positioned on a printing surface plate 16 of a printing device 10 so as to serve as an exposure region. A negative film 12 is placed on the printing surface plate and covered with an overlay sheet. A squeeze roller 22 of a squeeze unit 20 rolls over the overlay sheet along the longitudinal direction of the printing plate to perform the squeeze. Since the longitudinal dimension L of the printing plate B is shorter than the printing width 2W, the squeezing time can be made shorter than the time required for the squeezing in the direction of the width. And even in a printing plate having a shorter width, the moving distance of the squeeze roller is shorter than that in a conventional method, and hence the squeeze time can be made shorter.
