Abstract

PURPOSE:To improve the resolution of the titled printer and to simplify its manufacture and to reduce production cost by providing plural pieces of printer heads consisting of numerous LED chips arrayed in the direction of main scanning in a manner that the phases of the LED chips shift in the said direction. CONSTITUTION:The plural, for instance, two pieces of the printer heads 3 and 4 are mounted on a frame 2 being shifted in the direction of subscanning shown by the arrow (a). The printer heads 3 and 4 are long in the direction of main scanning shown by the arrow (b), and are made parallel with each other. The printer heads 3 and 4 have the numerous minute LED chips 3a and 4a arrayed in the direction of main scanning with equal intervals. When the pitch of respective LED chips 3a and 4a are P, the printer head 4 is so located as its LED chips 4a are shifted by 1/2P from the LED chips 3a of the printer head 3 in the direction of main scanning, for which a spacer 5 is interposed between the frame 2 and the edge of the printer head 4 for purpose of positional adjusting.

置調整用のスペーサ５が介在されている。Embodiment An embodiment of the present invention will be described in detail with reference to the drawings. In the figure, 1 is the printer main body, 2 is its frame, and the frame 2 has a plurality of printers arranged back and forth in the sub-scanning direction (arrow α direction). For example, two printer heads 3 and 4 are attached. These printer heads 3 and 4 have an elongated shape in the main scanning direction (arrow direction), and are attached to the frame 2 in parallel to each other. Many micro LED chips 3a
, 4a are arranged in parallel at equal intervals. Furthermore, when each T and HD chip 3α#4α pitch is P, frame 2 is set so that the LED chimp 4α of the other printer head 4 is shifted by 14p in the main scanning direction with respect to the LED chip 3α of one printer head 3. A spacer 5 for position adjustment is interposed between the ends of the printer head 4.

An image signal from the line 6x and an image clock signal from the line 7 are input to the drive circuit. These image data signals and image clock signals are divided and sent to the output side of the drive circuit.
The chips 3a and 4a are alternately selected, and the LED chip 3a
, 4a allows image data to be recorded on a recording medium such as a photoreceptor (not shown).
