Abstract: A smoother includes a conveying device for a molded body; a pair of arms that are respectively disposed to face both widthwise ends of the conveying device, and in which longitudinal ends of the arms are swingable in upward and downward directions with respect to a conveying surface of the conveying device; a smoother plate fixed to a pair of facing ends of the longitudinal ends of the pair of arms; weights that are respectively attached to the pair of arms and are movable along a longitudinal direction of the arms; a weight position changing device configured to change positions of the weights on the arms; and a first control device configured to control the positions of the weights on the arms via the weight position changing device.

Abstract: A thermal head capable of reducing a possibility of separation of a connector is provided. A thermal head includes a substrate; a plurality of heat generating portions disposed on the substrate; a plurality of electrodes which are disposed on the substrate and are electrically connected to the plurality of heat generating portions, respectively; and a connector including a plurality of connector pins which pinch the substrate and are electrically connected to the plurality of electrodes, respectively, and a housing for containing the plurality of connector pins. The housing is disposed adjacent to the substrate in a sub-scanning direction, and the housing includes a support portion disposed under the substrate. This can reduce a possibility of separation of the connector.

Abstract: A gypsum board forming device (10) constitutes an apparatus of producing gypsum boards. A layered formation of a lower sheet (1), an upper sheet (2) and a gypsum slurry (6) passes through a forming gate (40). The forming device forms the formation into a plate-like configuration with use of upper and lower plates (20, 30). The upper plate (20) is constituted from a fixed substrate plate (21) and a movable plate (22), and the movable plate is in surface-to-surface contact with the upper sheet of the layered formation. A plurality of actuators (50) is supported by the substrate plate. Each of the actuators applies an upward or downward load (P) to the movable plate locally for a local deformation of the movable plate owing to a deflection thereof. A gate size (T) is locally changed by displacement of the movable plate relative to the substrate plate.
