図面の簡単な説明を次のように補正する。
明細書７頁最終行「第２図ｂ」とあるのを「第１図ｂ」
と訂正する。Fig. 1a is a schematic diagram of the optical system of a conventional laser beam printer seen from above, and Fig. 2 is a diagram of the principle of correcting the optical system of a conventional laser beam printer.
Figure C is an enlarged view of the laser photodetector, Figure 2a is a block diagram of the optical system control, Figure 2 is an optical needle control time chart, and Figure 3 is the optical system of the laser beam printer according to the present invention. It is a schematic diagram of the system. In the figure, 1 is a laser, 2 is a laser beam modulator, 3 is a polygon mirror, 4 is an Fθ lens, 5 is a mirror, 6 is a laser photodetector, 7 is a cylindrical lens, 8 is a photosensitive drum, 9 is a polygon motor, 10 is a detection element, 11 is a detection circuit, 12 is a printer control circuit, 13 is a laser beam modulator drive circuit, and 14 is a concave cylindrical lens. Amendments Showa 5 & IZ 16 The brief description of the drawings has been amended as follows. The last line of page 7 of the specification “Figure 2 b” should be replaced with “Figure 1 b”
I am corrected.
