PURPOSE:To combine a panel with an adjacent panel or a wall in a state of a regular attitude by moving the panel or an auxiliary panel after the stopping of the vibration of the panel is confirmed. CONSTITUTION:After a panel 5 is temporarily stopped directly before it is brought into contact with a wall 3 or a preceding panel 5, a vibration detector consisting of a projector 11 and a light receiver 9 is operated, and output signals from the light receiver 9 are continuously transmitted for a time longer than a specific set-time (for example 2 seconds). According to the constitution, the stopping of the vibration of the panel 5 can be detected, and the panel 5 can be combined with the adjacent panel 5 or the wall 3 in a state of a regular attitude by traveling the panel 5 again based thereon. |
