PROBLEM TO BE SOLVED: To compactify a piston-cylinder type depositor. SOLUTION: This depositor is equipped with a cylinder 12 equipped with a raw material entrance 32 for receiving the raw material from a hopper and a raw material exit 43 for discharging/supplying the raw material received in the cylinder, a valve 24 made as capable of rotating between a raw material-receiving position by being inserted from the opening of a first end part of the cylinder, opening the raw material entrance and closing the raw material exit, and a raw material-discharging position for closing the raw material entrance and opening the raw material exit, a piston 26 being inserted from the opening of a second end part of the cylinder and made as capable of sliding in an axial line direction of the cylinder, a first servo motor 28 set at the opening side of the first end part of the cylinder for driving the valve, and a second servo motor 30 installed as adjacent to the first servo motor and rotational/reciprocal movements-converting means 48, 50 joined in between the rotary output shaft 44 of the second servo motor and the piston 26 and changing a rotating movement to a linear movement.
