Fixing mechanism of optical scanning device and image forming apparatus
A fixing mechanism of an optical scanning device, the optical scanning device emitting a light beam and performing a scanning, the optical scanning device further being fixed to a frame at an external part, the optical scanning device further including a housing, and the fixing mechanism including: a penetration hole provided in the frame; and a protruding pin provided at both ends of the housing thereby forming a plurality of protruding pins, wherein at least one of the plurality of protruding pins is insertable to the penetration hole formed in the frame; and a biasing member biasing the housing in a direction.
1. A fixing mechanism of an optical scanning device, the optical scanning device emitting a light beam and performing a scanning, the optical scanning device comprising a housing that is fixed to a pair of frames at an external part, the pair of frames facing each other and the fixing mechanism comprising:
a penetration hole provided in each of the pair of frames; and
a plurality of protruding pins each provided at a respective end of the housing of the optical scanning device and each pin extending in a direction transverse to the pair of frames, wherein at least a first one of the plurality of protruding pins is insertable into the penetration hole formed in a first one of the frames; and
a biasing mechanism biasing the housing of the optical scanning device in a direction transverse to the pair of frames,
wherein:
the biasing mechanism comprises:
a plate member fixed to the first one of the frames;
a header pin passing through the plate member and fixed to the housing; and
a biasing member provided between a head of the header pin and the plate member that biases the header pin away from the plate member; wherein
the plate member comprises a fitting hole through which the at least first one of the plurality of protruding pins is fittable; and
a notch formed in the first one of the frames at the location of the fitting hole in the plate member.
2. An image forming apparatus comprising:
an optical scanning device emitting a light beam and performing a scanning;
an image supporting body creating an electrostatic latent image by being irradiated with the light beam; and
an imaging device creating a toner image by developing the electrostatic latent image, wherein
the optical scanning device is fixed by the fixing mechanism according to claim 1 .
