Power supply device for supplying a drive power to a movable object

A power supply device for a moveable object comprising:

• a power supply member which is in the form of a plate and connected with a power source;
• the power supply member including:
• a first conductive plate electrically connected with one of positive and negative terminals of the power source;
• a second conductive plate electrically connected with the other terminal of the power source;
• a first insulating layer provided between the first conductive plate and the second conductive plate;
• a second insulating layer provided on the other surface of the second conductive plate that does not face the first insulating layer;
• a plurality of supply electrode members attached on an outside surface of the second insulating layer, the plurality of supply electrode members being spaced from one another, said first insulating layer, said second conductive plate and said second insulating layer having aligned openings, first conductors passing through said aligned openings and electrically connecting said first conductive plate to one of said supply electrode members, said first conductors not being electrically connected to said second conducting plate, said second insulating member having passages, second conductors passing through said passages and electrically connecting said second conductive plate to another one of said supply electrode members;
• a plurality of current collecting electrode members provided on a movable object which is movable on a planar surface, one of said current collecting electrode members being operable to come into contact with said one of said supply electrode members connected with the first conductive plate, and another one of said current collecting electrode members being operable to come into contact with said another one of said supply electrode members connected with the second conductive plate.
