PURPOSE:To largely open an upper frame and to smoothly close it. CONSTITUTION:In a printer 20, a photosensitive unit U is attached to the upper frame 30 so that it can move back and force in a direction shown by an arrow D or E. A lower frame 40 is provided with a shaft guide formed on a receiving part 43 and a unit guide 46 installed on the cover 45 of a fixing device 9. When the upper frame 30 is closed, the photosensitive unit U abuts on the unit guide 46 to be moved in a direction shown by the arrow E. |
