Abstract: PURPOSE:To realize quick rising and to eliminate the need of preheating in the midst of standby by using a specified toner and providing a carrying means for carrying a recording medium and plural light sources arrayed in the direction nearly orthogonally crossing the carrying direction of the recording medium in a carrying path. CONSTITUTION:This fixing device 20 is provided with plural light sources 2 arrayed in the direction orthogonally crossing the carrying direction of the recording medium in the carrying path for plain paper, and a means 25 for heating or pressurizing the recording medium is arranged on the lower side with respect to the light source in the carrying direction. The carrying means is constituted of the means 25 and a paper ejecting roller 4. Since plural light sources 2 are used, the lighting responsiveness of the individual light source 2 is made quick, and radiant energy borne by one light source 2 is reduced. Meanwhile, in the case of utilizing such dispersed light energy, toner which is fixed with <=3J/cm<2> light energy is used as the toner. By using the light sensitive toner, high speed fixing is realized and printing quality is improved.

Inventor: NISHIMURA TADAYUKI
IPC: G11B5/187
Filed: 1990-09-13
Abstract: PURPOSE:To reduce the wear of a magnetic tape and to travel a magnetic medium while the medium is closely attached to a gap by instantaneously accelerating a lapping tape to a normal velocity and reversing the tape at the time of reciprocatively sliding the tape. CONSTITUTION:The lapping tape L is closely attached to the sliding surface of a recording medium and reciprocatively slid to lap the medium. The tape L is accelerated to a normal velocity in the short time of 0.7-0.9msec and reversed. Accordingly, the tape L collides with the slopes (l) and r on this side of a protrusion, and the slopes (l) and r are concentratedly lapped. Consequently, even if the sliding surface is worn, a lapped surface is exposed, the protrusion surface is not excessively lapped, and the shape of the sliding surface prior to lapping is held. Consequently, the wear and damage of the recording medium are reduced, the tape T is closely attached to the gaps G1 and G2 and traveled, and the electromagnetic conversion characteristic is improved.
