定着させる方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flash fixation control method for an information recording device using continuous paper, and in particular, by controlling the flash timing, it is possible to reliably transfer print data developed with toner near the end of the printing paper. Regarding the method of fixation.

れない所謂未定着領域ができる問題があつた。 Conventionally, in information recording devices such as electrophotographic printers equipped with a flash fixing device made of a xenon flash lamp, etc., even when the end of continuous paper is detected and the data being printed on the photosensitive drum is stopped, the photosensitive drum is already The data printed on the paper needs to be transferred to paper and fixed completely. For this purpose, it is necessary to detect the end of the paper quickly, but this is difficult due to the structure of the device. Also,
During printing, it is necessary to apply appropriate tension to the paper passing through the fusing unit, so a skirt is installed on the paper exit side of the fusing unit to slide and pull the paper at a speed several percent faster than the specified paper speed. A roller called a flora is provided. Therefore, the unfixed data area transferred to the paper near the end of the paper is pulled by the skirt roller alone when it leaves the section, usually called the tractor, which transports the paper at a predetermined paper speed. As a result, the overlapping margin of the regular flash fixing zones is exceeded, resulting in a problem that a so-called unfixed area is created in which the fixing is not done due to the faster speed of the scat flora.

好ましくない。 FIG. 1 shows an embodiment in which the present invention is applied to a laser printer. In the figure, reference numeral 1 denotes a laser beam generation section that modulates the laser beam according to the print data signal and generates the modulated laser beam, and usually stores print data for one page of printing paper. Signal processing is performed page by page. Reference numeral 2 is a sensitive drum on which exposure with a laser beam, development with toner, etc. are performed. Reference numeral 3 indicates a folded sheet of continuous paper that has sprocket holes for paper feeding at both ends and is perforated at predetermined intervals. Reference numeral 4 denotes a paper feeding section which conveys the continuous paper 3 at a constant speed by two tractors 4' as shown in the figure. Reference numeral 5 denotes a transfer section which includes a charger in the center of the paper feed section 4 and transfers the toner image developed on the photosensitive drum 2 onto the continuous paper 3. 6 shows a flash fixing device which is composed of three xenon lamps inside a reflecting plate. Further, on the back side of the flash fixing device 6 with the continuous paper sandwiched therebetween, an auxiliary means 6' that is suctioned with air is included for cooling and to prevent the paper 3 from fluttering within the fixing device. This flash fixing device 6 usually takes several milliseconds.
During this period, a powerful light energy is generated, which fixes the length of the effective fixing width l4 of the flash fixing device, and usually overlaps several millimeters in accordance with the constant speed determined by the paper feed section 4. It will be established. this number
The overlap of mm is predetermined in advance to ensure that unfixed portions never occur, taking into consideration the margin for retrying when the flash fixing device causes a misflash and the speed fluctuation of the continuous paper 3. However, if this amount of overlap is made too large, problems such as an abnormality in the fixing state and the occurrence of wrinkles due to local shrinkage of the continuous paper 3 occur, so that it cannot be made too large. Further, in order to prevent an increase in the power supply capacity of the flash fixing device 6, increasing the overlap is not preferable because the flash timing becomes earlier and the power supply capacity increases as a result.

例えば光学的に検出するものである。 The flash fuser 6 is shown as having three xenon lamps, but in order to prevent the power supply capacity of the flash fuser from increasing, the three xenon lamps are not flashed at the same time, but are flashed one after the other in an appropriate order. The books are flashed one by one. This is advantageous because it allows fine control when controlling the flash timing. 7 is provided in order to apply appropriate tension to the continuous paper 3 during printing, and is normally set to rotate at a speed several percent faster than the speed determined by the paper feed section 4, and during printing, it rotates on the continuous paper 3. It's slipping and spinning. 8 is a tension damper which absorbs sudden speed changes of the continuous paper 3. Reference numerals 9 and 10 indicate paper end detectors, which are transmission-type light emitters and receivers. In particular, the detector 10 is also used to detect paper jams and the like. Reference numeral 11 denotes a paper running detector which detects signals from the sprocket holes of the continuous paper 3 optically, for example.

うにしたものである。 The detection signal from the paper end detector 9 is notified to the laser beam generator 1, and the laser beam generator 1
receives this signal and stops the laser beam at the page break. However, the photosensitive drum 2
Since the information exposed to light needs to be transferred onto continuous paper, even if the paper end detection signal is a page break, only the remaining portion of continuous paper 3, l 1, will be transferred to l 2 . It must be. Furthermore, the continuous paper 3 after being transferred will not be fixed unless it completely passes through the flash fixing device 6. Due to the structure of the normal device, the length l1 - l2 is much shorter than the length from the outlet of the paper feeding section 4 to the outlet of the flash fixing device 6, which is indicated by l3 in the figure. Therefore, the terminal end of the continuous paper 3 comes off from the paper feed section 4. In this state, the toner image transferred near the end of the continuous paper 3 is almost sent at the speed of the scraper roller 7, resulting in an unfixed area as described above. In order to solve this problem, the present invention detects the end of the continuous paper 3 with the detector 10,
A change in paper speed is detected by a signal from a paper running detector 11, a change in the movement of the tension damper 8 is detected, or a change in paper speed is detected by a signal from a paper end detector 9 by a detector 10. By using a signal predicted earlier, the flashing timing of the flashing fixing device 6 is set so that the flashing is performed at a slightly earlier timing that matches the speed of the continuous paper 3 during the period when only the skirting roller 7 is being driven. It is something.
