Abstract: To downsize a curved transport route through which a transport target is transported without being deformed. A transport path 401 includes a first curved transport tubular-body unit 415B having a first curved shape in which a bottom surface 411B located beside an air blowing tube 100 bulges into a convex shape toward the air blowing tube. The first curved transport tubular-body unit is configured to increase a distance H between the bottom surface and a top surface 413B opposite to the bottom surface from each end portion toward an intermediate portion in a transport direction x to prevent a banknote P retained by a transport body 500 from coming into contact with the top surface.

Abstract: An election terminal apparatus includes an integral-type display/input unit constituted by a liquid crystal display unit and a tablet unit for input data. The display unit displays a first screen including icons corresponding to candidates. A voter operates the tablet unit to designate a candidate for whom he/she wants to vote. The election terminal apparatus discriminates the candidate designated by the voter, and causes the liquid crystal display unit to display an image for allowing the voter to input the candidate name or the like with handwriting. When the voter handwrites the candidate name or the like on the table unit, the election terminal apparatus performs character recognition with respect to the handwritten pattern. When a candidate specified by the recognized characters coincides with the candidate designated first, the election terminal apparatus increments the vote count of the candidate by one.

Abstract: A dozing system for a bulldozer with which dozing can be carried out by a simple operation without giving a great deal of fatigue to the operator.When the running slip of a vehicle body is not detected by a running slip detector, a blade is lifted or lowered by a comparison controller such that an actual tractive force of the vehicle body detected by an actual tractive force detector becomes coincident with a target tractive force set by e.g., a dial, whereby the amount of loads applied to the blade by excavating and moving earth can be maintained constant. On the other hand, when the running slip of the vehicle body is detected by the running slip detector, the comparison controller lifts the blade, thereby reducing the amount of loads applied to the blade by excavating and moving earth in order to eliminate the running slip.
