An auger type ice making machine comprises an ice storage level detecting apparatus (5) including an ice storage level sensing plate (5a) disposed within an ice guide barrel (3) at a position opposing to an ice discharge port (2). A pair of guide plates (7) for guiding ice discharged from the ice discharged port toward a center portion of the ice storage level sensing plate are mounted on both side walls (3b) of the ice guide barrel (3) closely adjacent to the ice storage level sensing plate (5). By mounting the paired guide plates (7), gaps otherwise taking place between the ice storage level sensing plate (5) and the ice guide barrel (3) are closed to thereby prevent the ice from moving to the rear side of the ice storage level sensing plate by circumventing it. The ice storage level sensing plate is thus protected from being blocked. Another guide plate (9) inclined toward a center region of the ice storage level sensing plate (5) is provided on a ceiling plate (3a) of the ice guide barrel (3) closely adjacent to a tip end (5d) of the ice storage level sensing plate (5a) to thereby prevent ice from intruding between the ice storage level sensing plate and the ceiling plate (3a).
