Description of the Related Art A foreign matter detecting device of this type is provided with a pair of rollers that are pressed into contact with each other so that the foreign matter in the mail can be detected by passing the mail between the rollers. . That is, the pair of rollers is composed of a fixed roller and a moving roller that moves in a direction of coming close to and away from the fixed roller, and the moving rollers are provided by the thickness of the mail. It moves around the fulcrum and returns by spring force after passing the mail.

判定され、検出がないと、通常の郵便物と判定される。
定形外と判定された郵便物は排除される。When the moving roller moves by a predetermined distance when the mail is passing, it is detected by a detection sensor. If this is detected, the postal matter is determined to be out of the standard form (postal matter containing foreign matter or hard matter that interferes with transportation and detection), and if not detected, it is determined to be a normal postal matter.
Mail that is determined to be out of size is rejected.

By detecting the foreign matter, the shape such as the thickness and the length of the foreign matter can be determined. That is, when the first and second moving rollers are alternately moved by a predetermined distance and detected by the first and second detecting means during passage of the transported object, the foreign matter in the transported object is a short foreign matter. For example, it is determined that the object is a hard spherical object, and the first and second moving rollers simultaneously move and are detected by the first and second detecting means, and at the same time, the first and second moving rollers are detected. When the rotation base is rotated by the simultaneous movement of the blades and the rotation is detected by the third detecting means, it is determined that the foreign matter in the transported object is a long and thick foreign matter, for example, a thick sheet metal body. Further, although the first and second moving rollers move at the same time, the moving amount thereof is small and the first and second detecting means do not detect them, and only the rotation of the rotating base is the first. When detected by the detection means of No. 3, the foreign matter in the transported object is long and thin. If For example, it is determined that the thin sheet metal body.
