置における感材の落下防止装置。[Scope of Claim for Utility Model Registration] A photosensitive material case that stores a roll-shaped photosensitive material in which the photosensitive material is wound around a core material without fixing its ends, and a photosensitive material that is pulled out from the photosensitive material case and that is sandwiched between the photosensitive material cases. A pair of lead-in rollers sends out the photosensitive material in the sub-scanning direction while the photosensitive material is being conveyed in the sub-scanning direction while being held between the main roller and the nip roller. an exposure scanning section that records a duplicate image on the photosensitive material by scanning the photosensitive material; a cutter that is provided between the introduction roller and the exposure scanning section and cuts the photosensitive material into a predetermined length; a main control section that controls driving of the roller, the exposure scanning section, and the cutter, and the introduction roller moves the photosensitive material until the leading end of the photosensitive material is between the main roller and the nip roller. After being fed out and held between the main roller and the nip roller, the photosensitive material is cut to form a piece of photosensitive material of a predetermined length, and then the image is exposed to the photosensitive material piece by the exposure scanning section. In an image recording apparatus for recording, a trailing edge detection sensor is provided between the introduction roller and the photosensitive material case and detects a trailing edge of the photosensitive material; A fall prevention device for a photosensitive material in an image recording apparatus, comprising: an auxiliary control section that stops the introducing roller when a terminal end of the photosensitive material is detected by a terminal end detection sensor.
