ともない。As shown in the exploded perspective view of FIG. 3, an elastic member 10 is laminated on the surface of the optical box 1 on the back side of the lid 9.
The elastic member 10 is attached to the back surface of the lid 9 with a double-sided adhesive tape 11 indicated by hatching, and the double-sided adhesive tape 11 is provided only at, for example, a central portion of the lid 9. As a result, the area of the double-sided adhesive tape 11 can be significantly reduced, so that the cost can be reduced.
When the lid 9 is removed from the optical box 1, the elastic member 10 comes off integrally with the lid 9 and does not shift from the lid 9.

As described above, there are problems such as the volatilized organic solvent eroding plastic parts and contaminating optical parts. As in the embodiment, reducing the bonding area of the double-sided adhesive tape 11 can reduce the amount of the organic solvent to be volatilized, shorten the time for volatilizing the organic solvent, and further reduce the cost. become.

ぎることがない個所を意味している。Since the elastic member 10 can be bent by its own weight to the extent that it blocks the optical path of the laser beam, it is preferable to appropriately provide a double-sided adhesive tape 11 as an adhesive member at a necessary position. The necessary portion means a portion where the double-sided adhesive tape 11 is attached thereto and the lid portion 9 and the elastic member 10 are adhered to each other so that the optical path of the laser beam is not blocked even if the elastic member 10 is slightly bent. ing.

Means that the double-sided adhesive tape 11 is provided in a direction in which the double-sided adhesive tape 11 can be provided long in one direction. are doing. That is,
This is because the elastic member 10 is easy to bend in one long direction.
Does not bend significantly and does not block the optical path of the laser light.

That is, the elastic member of the present embodiment substantially covers all the region corresponding to the surface of the cover 9. It has a large area to cover. The reason is that in the present embodiment, the step of assembling the scanning optical device can be simplified by eliminating the step of hollowing out the elastic member. Further, since the elastic member 10 has a large area, it is easy to grasp and the assembling work is easy. Note that, in order for the elastic member 10 to cover substantially all, the contour of the elastic member 10 does not necessarily have to be the same as the surface of the lid 9.

Alternatively, it may be provided at a certain angle with respect to the optical axis of the fθ lens 7. In particular, it is preferable to provide the double-sided adhesive tape 11 in one long direction along the optical axis of the fθ lens 7. That is, the direction is a particularly long direction on the bottom surface of the optical box 1. Alternatively, a double-sided adhesive tape 11 may be provided above all or at least a part of the optical path of the laser beam.

May or may not be located directly above the polygon mirror 6, but it is preferable to be located directly above the polygon mirror 6 because the polygon mirror 6
This is because, even if the elastic member 10 immediately above is bent by receiving heat from the scanner motor 5, it can be prevented from contacting the polygon mirror 6.

When the elasticity of the elastic member 1 is very weak, the double-sided adhesive tape 11
0 is adhered to the lid 9. Thereby, it is possible to avoid the possibility that the portion of the elastic member 10 adhered by the double-sided adhesive tape 11 hangs down and closes the light passage area of the fθ lens 7 and the cylindrical lens 4.

とができる。As a result, the elastic member 10 is firmly adhered and fixed to the lid 9 above the optical path, so that even if the elastic member 10 is deformed under the influence of its own weight or heat, the elastic member 10 is deformed. This can prevent the optical path from being deformed and blocking the optical path.

いられるとしても、同様である。The double-sided adhesive tape 11 is provided directly above the polygon mirror 6 and the optical path of the light beam. The position directly above the cover 9 corresponds to the direction of the cover 9 and the surface of the optical box 1 facing the cover 9. This is the same even if, for example, the optical box 1 to which the lid 9 is attached is used so that the lid 9 is located below the optical box 1.

Alternatively, a liquid or viscous liquid adhesive having fluidity may be used. However, the band-shaped double-sided adhesive tape 1
Using 1 not only reduces costs,
Since the double-sided adhesive tape 11 itself has a band shape, it is easy to attach and the work is easy, which is preferable.

In that case, it is only necessary to provide the adhesive substantially in the form of a strip on the optical axis. This can be reduced, and even if the adhesive contains a volatile component, the consumption of the adhesive itself can be reduced, so that the volatilization amount of the volatile component can also be reduced.
