面の２方向が最低必要であつた。"Prior Art" In a conventional laser beam printer, as shown in FIG. 5 of a perspective view, an operation method for feeding and discharging an object to and from a printer main body 23 is performed by a sheet feeding side of a sheet feeding cassette 7 and a sheet discharging roller. The two directions, that is, the discharge side of the print carrying the image from the pair 24, the take-in / out side of the drum cartridge 5 and the side surface of the printer body 23, are required at least.

し、排出ローラ対２４により排出する。A conventional laser beam printer combining the electrophotographic method and the laser scanner shown in FIG.
The configuration is as shown. Reference numeral 1 denotes a scanning optical device, which is internally composed of a semiconductor laser, a collimator lens, a polygon mirror rotated by a motor, and an imaging lens group. A reflecting mirror 2 guides the light beam scanned by the scanning optical device 1 onto the surface of the photosensitive drum 3. The scanning optical device 1 and the reflecting mirror 2 are mounted on a base 4. Reference numeral 5 denotes a drum cartridge which develops the latent image formed by forming an image on the photosensitive drum 3 at this portion, transfers the latent image to the paper sent from the paper feed cassette 7 by the transfer charger 9, and sends it to the fixing device 6 to fix it. Then, the sheet is discharged by the pair of discharging rollers 24.

必要とした。“Problems to be Solved by the Invention” Due to such a configuration, the drum cartridge 5 is positioned with reference to a member different from the reflecting mirror 2, and the reflecting mirror 2 is positioned on the base 4, so that When the positioning with respect to the photosensitive drum 3 is difficult, and when vibration occurs, the reflecting mirror 2 and the photosensitive drum 3 repeat relatively small displacements, so that the image formation on the photosensitive drum 3 becomes inaccurate. Also, drum cartridge 5
Cannot be taken in and out due to the fixing device 6 on the paper feeding / discharging side, and cannot be taken out because the reflecting mirror 2 and the base 4 are fixedly installed in the upper direction. When the front of the car was used as the front, the method of taking it out from either one of the left and right sides was taken, so a lot of operating space was required on the side.

力によつて振動防止に十分な力で押圧される。When replacing or inspecting the cartridge 8, the opening / closing lid 12 is opened around the hinge 22 to bring the reflecting mirror 13 to the non-acting position to open the opening 21, the cartridge 21 is taken out through the opening 21 and the printer is opened again through the opening 21. When the opening / closing lid 12 is rotated in the counterclockwise direction about the hinge 22 to close the opening 21, the both ends of the reflecting mirror 13 are brought into contact with the reflecting mirror pressing positioning reference surface 15. In this state, the opening / closing lid 12 is not sufficiently closed, and when the opening / closing lid 12 is further pressed, the opening / closing lid 12 closes the opening 21 against the spring force of the reflecting mirror support member 14.
A fixing means such as a latch (not shown) locks the open / close lid 12.
By the last closing operation of the opening / closing lid 12, the reflecting surface of the reflecting mirror 13 is pressed against the reflecting mirror pressing / positioning reference surface 15 by the elastic force of the spring with a force sufficient to prevent vibration.

は変化しない。As a result, the vibration and backlash of the opening / closing lid 12 are absorbed by the reflecting mirror support member 14, and the reflecting mirror 13 is constantly pressed against the reference surface 15 on the cartridge 8 so that the pitch unevenness of the scanning line does not occur. Since the reflecting mirror support member 14 is provided so that substantially both ends of the reflecting surface of the reflecting mirror 13 press against the reflecting mirror pressing positioning reference surfaces 15 and 15 of the cartridge 8, the reflecting mirror 13 is located above the reflecting mirror pressing reference surfaces 15 and 15. Even if is moved along the reflecting mirror pressing and positioning reference planes 15, 15, the image forming position does not change.

Iron pieces 16, 16 are provided on the reflecting mirror pressing positioning reference surfaces 15, 15 on both sides of the
Reflector 13 is provided by fixing 17 and 17 integrally.
The magnet piece 17 is attracted to the iron pieces 16 and 16 which serve as the reflecting mirror pressing and positioning reference surface on the cartridge 8 to prevent the reflecting mirror 13 from moving independently of the cartridge 8 against external vibration. The relationship between the magnet and the iron piece may be reversed, and magnets of different polarities may be provided on the reflecting mirror and the cartridge, respectively.

である。By doing so, the reflecting mirror is firmly fixed to the cartridge 8 by the attraction force of the magnet and the elastic pressing force of the reflecting mirror supporting member, and is accurately positioned.
In addition, a rigid plate is integrally sandwiched between the reflecting mirror support member 14 and the reflecting mirror 13 so as to project further outward from the longitudinal end of the reflecting mirror 13, and the rigid plate is pressed against the reference surface 15. It is also possible to position the reflecting mirror 13 by means of.
