PURPOSE:To reduce the cost of a device by irradiating a light-receiving element provided to a projection of a panel with the light of a light-emitting element being lit simultaneously with the start of partitioning of a room, so that a motor for traveling the panel can be stopped. CONSTITUTION:When the forefront panel 1A traveling along a guide rail 5 abuts on a wall member 2, a light-receiving element 16a provided to a runner 9 being a projection of the panel 1A on one side is placed in the position opposite to the light-emitting element 16b of a front-end first photoelectric switch 16 being lit simultaneously with the start of partitioning of a room to receive its light, and the traveling motor for the panel 1A is stopped. When the other runner 10 of the panel 1A advances between the light-emitting element 17b of a second photoelectric switch 17 and a light-receiving element 17a to interrupt the light, the light-emitting element 16b of the first photoelectric switch being the second from the front is lit to stop the subsequent second panel 1B. Thus, without using a complicated device, respective panels 1 (1A, 1B) can be stopped for partitioning the inside of a room 6 (not shown). |
