Title:
PRINTER APPARATUS
Document Type and Number:
Japanese Patent JP2738321
Kind Code:
B2
Abstract:
PURPOSE: To form a block copy of a home printer accurately.
CONSTITUTION: The printer apparatus has a photosensitive drum 2, a laser light-scanning part 4 which casts spots of laser light to the photosensitive drum 2 via a polygon mirror 3 thereby to form electrostatic latent images, and a developing part 5 for sticking toners to the electrostatic latent images. Moreover, a movable mirror 7 is provided on a route of the laser light from the polygon mirror 3 to the photosensitive drum 2 to reflect the laser light towards a side 7A of the photosensitive drum or a predetermined direction 7B. A driving means 8 is also installed in the movable mirror 7 to drive the movable mirror 7 in a direction opposite to the laser light. Further, a heat-generating drum 9 is set at the side of the predetermined direction 7B of the movable mirror 7 to transfer a thermoplastic film 10 for a form plate and detect the laser light shed in spots from the movable mirror 7.
