Title:
ELECTRIC TRANSPORTING VEHICLE
Document Type and Number:
Japanese Patent JP3795113
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain an easy-to-operate electric transporting vehicle.
SOLUTION: A variable resistor VR1 for steering control outputs a manual steering signal Hs corresponding to the horizontal movement of an operation lever. This manual steering signal Hs is converted into a manual steering signal Hs' by a manual steering signal generating circuit 30. A variable resistor VR2 for speed control outputs a manual speed signal Hv corresponding to the vertical movement of the operation lever. Also, a dead zone generating circuits 31, 32 output a '0' signal when each absolute value of the inputted manual steering signal Hs' and manual speed signal Hv is less than a fixed value and a '1' signal when it is greater than the fixed value. A switch 45 makes contacts 45a, 45b when the '1' signal is outputted from an OR-gate circuit 34 and breaks the contacts with the '0' signal.
