Abstract
An image forming apparatus comprises a carriage freely attached and removed containing a photosensitive sheet, copy paper whereon a latent image that was formed on the photosensitive sheet is transferred by pressure developing rollers, a winding shaft whereon the used photosensitive sheet is wound, a loading guide plate, capable of pivoting freely, incorporated in the carriage and installed on the opposite side of a jam processing operation section on the transportation path of the photosensitive sheet, a tension spring mounted on the loading guide plate that maintains the loading guide plate in a loading position guiding the photosensitive sheet toward the winding shaft, and in a retreat position creating a transportation path for the copy paper between the loading guide plate and a copy paper guide plate, a horizontal shaft mounted over the surface of the loading guide plate that drives the loading guide plate to a retreat position in accordance with the tension of the photosensitive sheet when the photosensitive sheet is wound on the winding shaft, a winding sensing switch that operates in response to the stretching action of the photosensitive sheet, and a contact member mounted on a member of the main body of the apparatus that drives the loading guide plate in the loading position when the loading guide plate is drawn out together with the carriage.
