PURPOSE:To reduce the number of components, by increasing the moving distance of a carriage at recording much more than that at reading, and applying a driving force releasing trigger of recording chart carrying depending on the position of the carrige. CONSTITUTION:The moving range of a carriage 10 is made longer much more at the end than that at recording, a lever A is lifted up counterclockwise around a shaft 30 with the movement up to one-dotted chain line position, and held to the state lifted up at a lever C. Since the carrige 10 pushes the reading lever C and a shaft 39 is turned clockwise at the end of movement of the carriage 10, the engagement beteen the levers C and A is released, a lever A is turned clockwise around the shaft 30 with a force of a spring 31, a lever D linked to a fulcrum 34 is drawn downward to turn a rachet wheel 35 and an original feeding roll is driven. The lever A of the storage mechanism is released at recording, the recording feed roll is driven and the energy storage mechanism of the original feed roll is released at the same time, and the recording chart feed roll and the original feed roll are driven at the same time. |
