Abstract
In a printing position adjusting mechanism employed in an image forming apparatus using a continuous form recording medium having perforated tear lines at predetermined intervals, are sensors are provided for detecting a leading edge of the recording medium and outputting a predetermined signal synchronously with the feeding of the recording medium. With the printing position adjusting mechanism, the period of time, between the detection of the leading edge of the continuous sheet and outputting of the predetermined signal, is adjustable. The apparatus starts printing upon receiving the predetermined signal which is outputted after a predetermined time has elapsed after the leading edge of the continuous sheet is detected.
Claims13
An apparatus for forming an image on a recording medium, said apparatus comprising:
- (a) means for feeding the recording medium;
- (b) means for generating a pulse signal, the number of pulses of said pulse signal corresponding to the feeding amount of said recording medium;
- (c) means for detecting a predetermined position on said recording medium;
- and
- (d) means for shifting the phase of said pulse signal in relation to said predetermined position of said recording medium, wherein said means for shifting the phase of said pulse signal comprises means for mounting said means for generating a pulse signal, said mounting means being movable to change the position of said means for generating a pulse signal.
