The entry/control unit includes a main unit in which a mounting space is formed, a cross bar case, one or more elastic members of which one end is fixed to the cross bar case, the cross bar which is connected to the elastic member and the cross bar case, a limit switch producing the electric signal equipped on the top of the main unit in order to rotate. The drive unit includes a base fixed on the top of the main unit, a drive motor which the cross bar case and turning axis are connected to, a reducer which is connected to the drive motor and decelerates the rotation. A first connector of which one end is connected to reducer, a rotary connection arm which is connected to the first connector, a second connector of which one end is connected to the connection arm, a shaft axis which is connected on the top of the base while one end is connected to the second connector and the other end is connected to the cross bar. In case of being provided the electric signal from the limit switch(35), the control unit controls the drive motor and make the cross bar release.
