In an image recording apparatus equipped with an automatic paper passing function, the image recording apparatus has an auxiliary member located at a position such as that of a rotatable first roller provided in the storage means, and a rotatable first roller that approaches and separates from the first roller. a holding means capable of holding the photosensitive recording medium or its leading end with a second roller that is supported by the second roller; and a biasing means that always brings the first roller and the second roller into contact with each other. , a coupling means provided at an end of the second roller and coupled to a drive shaft provided on the main body device side when the storage means is attached to the main body device; a movable member movable in the same direction as the moving direction of the second roller; and a movable member provided at an end of the movable member, and when the storage means is attached to the main body device, comes into contact with the coupling means and deforms in the attachment direction. an opening means comprising a displacement member that moves the auxiliary member between a position covering the winding means and a position away from the winding means, and simultaneously moving the opening means between a position close to and a position away from the coupling means. and an automatic paper passing means for moving the paper between the second roller and the first roller, when the storage means is mounted on the main body device, the coupling means deforms the displacement member in the mounting direction, and moves the displacing member between the second roller and the first roller. When the photosensitive recording medium is automatically fed, the displacement member of the opening means is moved in a direction away from the coupling means by the automatic paper feeding means to recover from deformation, and the photosensitive recording medium When the automatic paper passing of the recording medium is completed, the automatic paper passing means returns the opening means to the original position, and the displacement member thereby moves the second roller against the first roller against the urging means. An image recording device characterized in that it is separated from the image recording device.
