摘要：
A transmission type light sensor is disposed in the vicinity of the exit of a shooter, which has the exit thereof positioned above a grass-bag opening, and the fullness of the grass-bag is detected when the light blocking state of the sensor continues longer than a predetermined time. A light emitting portion and a light receiving portion of the light sensor are positioned opposite to each other so that their optical axes are in coincidence, and they are firmly attached to both ends of a light sensor mounting member. The light sensor consists of a light sensor main body which is placed at one side of a cover, and a retroreflective board placed at the side of the cover opposite to the light sensor main body for reflecting incident light from the light emitting portion in the direction of incidence.
