In one embodiment, a supply mechanism is provided. The supply mechanism supplies accumulated paper sheets to a takeout position sequentially. A takeout belt having adsorption hole runs along a surface of the takeout position. An opening of a negative pressure chamber is arranged so as to face the takeout belt. A suction unit sucks air existing at the takeout position via the opening and the adsorption holes. The suction unit causes a negative pressure to act on each of the paper sheets so that each is adsorbed onto an adsorption surface of the takeout belt. The suction unit has an air supply port to supply air into the negative pressure chamber. The air supply port is arranged so that the air supplied via the air supply port is directed to a position and in a direction different from those of the opening.

A mass measuring unit includes two driving rollers vertically separate from each other and intersecting the direction of conveyance of a mail matter. Servo motors for driving the driving rollers are connected to torque detection units. A control unit controls motor control units to cause them to impart a rate difference between the driving rollers to rotate the mail matter during its conveyance, and to cause the torque detection units to detect the torque values of the servo motors. The control unit compares the thus detected torque values with the torque values of the servo motors detected when the servo motors are idling without rotating the mail matter, thereby measuring the mass of the mail matter using a calculation unit.

According to one embodiment, a flow channel opening and closing device includes a first rotating plate provided rotatably along a face which crosses two adjacent flow channels, having a first fluid passing hole which overlaps with each of the two flow channels midway during rotation, which fully opens the one flow channel and blocks the other flow channel at a region except the first fluid passing hole by making the first fluid passing hole overlap with the one flow channel, and a second rotating plate provided adjacent to the first rotating plate and rotatably along a face which crosses the two flow channels, having a second fluid passing hole which overlaps with each of the two flow channels midway during rotation, which rotates to a position where the second fluid passing hole overlaps at least partially with the one flow channel when the first rotating plate rotates to a position where the first fluid passing hole fully opens the one flow channel.

A valve device is provided with a first block connected to an upstream-side suction tube that is connected to a negative-pressure chamber, a second block connected to a downstream-side suction tube that is connected to a pump, first and second shielding plates rotatably interposed between the first and second blocks, and servo motors for rotating the shielding plates. Each of the shielding plates has a plurality of air passing holes, and are rotated in opposite directions.

According to one embodiment, a posture converting device includes two upstream-side correction rollers spaced apart in a direction intersecting with a conveying direction of a paper-like material, two downstream-side correction rollers arranged at a position spaced apart from the upstream-side correction rollers toward a downstream side in the conveying direction, and a control unit for independently controlling rotations of the four correction rollers, wherein the control unit rotates a conveyance posture of the paper-like material to some extent by making a speed difference between the two upstream-side correction rollers, and rotates the paper-like material to a desired conveyance posture by making a speed difference between the two downstream-side correction rollers.
