Abstract
Abstract @ A paper supply device for an electrostatic photographic printer which can significantly reduce an area for installation of the printer. A housing of the printer includes a base and a cover connected for pivotal motion in a vertical plane relative to each other. A picture image forming means including a photosensitive member and so on is mounted on the base. A paper supply cassette is mounted on the cover, and paper is drawn out from the paper supply cassette by means of a paper supply roller and then guided to the picture forming means by a paper guide which includes a guide plate mounted on the cover and another guide plate mounted on the base and disposed in opposing relationship to the guide plate on the cover. A gear wheel connected to the paper supply roll is meshed, when the cover is closed, with another driving gear wheel mounted on the base and connected to a motor. An engaging member is also provided on the cover and urged to engage with and hold the paper supply cassette from dropping off the cover.
