Claims (1)

[Claims for Utility Model Registration] 1. An elevator car, an optical space transmission device for signal transmission is installed in the car, and another optical space transmission device opposite to the car optical space transmission device is installed in the elevator tower. In an elevator that is fixedly installed and configured so that signals can be transmitted to each other regardless of the position of the cars, and that power for the cars is supplied from a battery on the car, a non-contact type is installed near the landing. The power receiving part of the non-contact power supply device is provided at a position opposite to the power supply part on the car side, and power is supplied to the car side without contact when both parts are facing each other. Characteristic elevator power transmission system. 2. The elevator power transmission system according to claim 1, wherein the power supply section of the non-contact power supply device is installed under the sill of the elevator hall door, and the car side power reception section is installed under the sill of the car door. 3. The elevator power transmission system according to claim 2, wherein the power supply part of the non-contact power supply device is installed under the sill of the hall door of each floor, so that power can be supplied to the car side when the car is stopped at any floor. 4. The elevator power transmission system according to claim 2, wherein the power supply part of the non-contact power supply device is provided in a pocket part of a hall door. 5. The elevator power transmission system according to claim 1, wherein signal transmission between the car and the control panel is performed by guided radio instead of optical space transmission. 6. An elevator power transmission system characterized in that both the power feeding part and the power receiving part of the non-contact power feeding device have a structure in which a coil is embedded in an insulating mold.
