PROBLEM TO BE SOLVED: To provide a compacted safety device, in which there is no trouble of the movement of an electric wiring with door open-close operation. SOLUTION: The safety device consists of rods 22 attached to the home door 4 so as to receive specified force and be pushed backwards by the collision of a foreign matter against the door stop section 21 of the home door 4 for a home door device for a platform, a reflector 30 mounted on the home door 4, and a photodetector 29 set up to a door storage case 1 for receiving reflected light from the reflector 30 by projection light to the reflector 30. The safety device has a light shielding mechanism 31 interlocked with the pushing of the rods 22 and set up on the home door 4 so that light reception is interrupted and a control section 17 provided at the side of the door storage case 1 so as to command door-opening driving for a specified time to a driving device 10 for opening and closing the door during a door-closing driving command by the operation of the photodetector 29 at the time of light shielding. |
