    摘要: A device for positioning a tip portion of a continuous form provided in a laser printer when the continuous form is set in the laser printer. The device includes a pair of fixing rollers provided at a position separated by a predetermined interval from a photosensitive drum, a tractor unit, a feed sensor, a tip sensor, and a control unit. The tractor unit is provided between the fixing rollers and the photosensitive drum to feed the continuous form toward the fixing rollers, the feed sensor outputs feed pulses in accordance with an amount fed of the continuous form, the tip sensor senses the tip portion of the continuous form. The control unit counts the number of feed pulses sensed by the feed sensor to feed one page of the continuous form so as, to discharge one page from the outlet mouth of the printer when a positioning of the tip portion is needed.

    摘要: A justification system for use in a printer employing a continuous recording form. The justification system comprises a timing pulse signal generating system which generates timing pulses in synchronism with the traveling of sprocket holes of the continuous recording form. The timing pulses signals for commencing the printing on each printing segment defined on the continuous recording form and the timing for stopping the advancement of the continuous recording form are controlled based upon the above timing pulse signals. With this control, printing can be executed with a correct positional relationship with rules on each printing segment, even if the continuous recording form is set in the printer with a slight misalignment in the direction of the travel path of the continuous recording form or if the form itself has expanded or contracted in its longitudinal direction due to the effect of humidity.

    摘要: A form feeding control device includes a sensor provided at an inlet mouth of a printer to sense whether or not a continuous form exists in the inlet mouth. A control unit feeds the continuous for transfer thereto of a printed image corresponding to one page of the continuous form. The printed image is then fixed on the continuous form. The control unit also feeds the continuous form to fix the printed image on one page when the sensor senses that the end of the continuous form has passed through the inlet mouth and that a printed image has been transferred to the continuous form.

    摘要: An appartaus utilizing a continuous-form sheet having a plurality of perforations at predetermined intervals of length is provided with a plate member for upwardly guiding the sheet discharged from the apparatus. A connect member provided on the plate member, as well as the apparatus, are arranged to be brought into and out of engagement with each other. The continuous-form sheet discharged from the apparatus is bent at the perforations and falls beyond the plate to be neatly folded.

    摘要: A device for controlling a process of stopping a laser printer having a printing unit including a sensitive drum and a fixing unit. The stopping process control device is provided with a detecting unit for detecting errors occurring in the laser printer, a determining unit for determining whether or not an error detected by the detecting unit is very serious, and a control unit for controlling the printing unit and the fixing unit. The control unit stops the printing unit and the fixing unit after completing a printing and a fixing of the page being printed when the determining unit determines that the error is less serious, and conversely, immediately stops the printing unit and the fixing unit when the determining unit determines that the error is very serious.

    摘要: A device for feeding a continuous form in a printer, the device having a timer for controlling the width of a drive pulse for a main motor feeding the form. The timer is formed of a plurality of timers controlled by software. These plurality of timers being, for example, three timers measuring a constant time, and one timer measuring a variable time which is varied in accordance with a feeding speed of the form. The width of the drive pulse is determined by summing up a time obtained by multiplying the constant time by three and adding the variable time.

    摘要: A justification system is provided for use in an electrophotographic printer. The justification system comprises a detector which detects the passage of individual segments of a continuous form which are being fed at a predetermined rate. A counter counts the number of main scannings of a laser beam carrying printing information over the surface of a photoconductive drum. A read control is connected to the detector and the counter and controls reading of main information stored by monitoring outputs from the detector and the counter so that printing of each segment always occurs at a predetermined position, synchronously with passage of the segments.
