Title: Image recorder
Inventor: IMAI SHINJI
IPC: H04N1/23
Filed: 1997-10-22
Abstract: PROBLEM TO BE SOLVED: To perform high-sensitivity image recording (recording of a latent image) without deteriorating the preservation alive of photosensitive heat developable recording material by heating the photosensitive heat developable recording material to be exposed at less than color developing temperature. SOLUTION: A scanning carrying means 48 is provided with a heating means 74 functioning as a means for heating recording material A submitted for exposure at less than the color developing temperature under a recorder X. In this recorder, the recording material A carried to the means 48 is exposed with a light beam L in a state where it is heated at less than the color developing temperature with heat from a heater 68, so that the latent image is recorded. The material A is exposed to perform photoset reaction and form the latent image. In such a case, generally speaking, the higher the temperature is, the more easily the reaction progresses. Then, the reaction progresses at the higher temperature even when an exposed value is the same.  By providing the heating means 74, the optical reaction of the material A, that is, exposure sensitivity is improved to realize the high-sensitivity latent image recording.

Title: Driving method for ink jet recording head
Inventor: SAYAMA TOMOHIRO
IPC: B41J2/045
Filed: 1997-10-22
Abstract: PROBLEM TO BE SOLVED: To enhance the recording speed by an arrangement wherein a nozzle meniscus expands or contracts a pressure generating chamber from stationary state to increase or decrease the pressure and the increased or decreased pressure is held as it is and then the pressure is controlled under such a state as the nozzle meniscus is pushed out to the ink jetting side through its own oscillation thereby the weight of ink to be jetted is increased. SOLUTION: In the vicinity of a moment where a nozzle meniscus (NM) is pushed out most toward the ink jetting side, i.e., the nozzle opening 7 side, second holding process (D2) is ended and then second discharging process (D3) for expanding a pressure generation chamber 4 to pull in the NM toward the generation chamber 4 is started and followed by subsequent processes. The driving waveform is compared between that case and a case where the second discharging process (D3) for pull in the NM toward the generation chamber 4 and subsequent processes are carried while omitting a first discharging process (D1) for pulling in the MN toward the generation chamber 4 and the second holding process (D2) for pushing out the NM toward the nozzle opening 7 side.  Since the weight of ink to be jetted can be increased when the step D3 and subsequent steps follows the steps D1, D2 because the NM is pushed out immediately before the step D3, recording speed can be enhanced.
