  Thereby, while performing the operation | work which inputs authentication information on an authentication screen, several monitoring screens can be confirmed simultaneously, and it becomes easy to find the occupant in a parking room, and can ensure safety.

  Specifically, when the monitor for authentication and the monitor for video confirmation are arranged separately, the monitor screen cannot be confirmed while staring at the monitor for authentication, There is a risk of overlooking people in the room.

  On the other hand, in the present invention, the authentication screen and the plurality of monitoring screens are within the same field of view, and are displayed on the monitor with a layout that does not require movement of the line of sight. Can be confirmed at the same time.

  Further, since the monitor displays a plurality of monitoring screens corresponding to the plurality of cameras, the operator can quickly confirm the camera video in the direction he / she wants to confirm.

According to a second invention, in the first invention,
The control unit enlarges and displays the plurality of monitoring screens when a predetermined operation requiring safety confirmation is performed.

  In the second invention, a plurality of monitoring screens are displayed after a predetermined operation, for example, an operation that requires safety confirmation such as pressing an emergency stop button is performed, or after the vehicle is stopped at a fixed position on the pallet. When a condition that requires safety confirmation is detected, such as when an exit is detected, the monitor is enlarged and displayed on the entire monitor. .

According to a third invention, in the first or second invention,
The controller continuously displays the plurality of monitoring screens on the monitor until a predetermined time elapses after the entrance door is closed, while the authentication screen for the next operator is displayed. It is characterized by being displayed.

  In the third invention, since a plurality of monitoring screens are continuously displayed on the monitor even after the entrance door is closed, safety can be ensured without overlooking persons in the parking room.

  The monitor also displays an authentication screen together with the monitoring screen. Therefore, the waiting time of the next operator is longer than when the authentication screen is displayed after the monitoring screen is hidden after a predetermined time. Can be shortened.

According to a fourth invention, in any one of the first to third inventions,
Provided in the vicinity of the monitor is an emergency stop button for urgently stopping the transfer operation of the transfer machine.

  In the fourth invention, when an operator finds an occupant in the parking room while looking at the monitor screen of the monitor, the emergency stop button disposed in the vicinity of the monitor can be quickly operated. Can be secured.

  According to the present invention, the authentication screen and the plurality of monitoring screens are within the same field of view and are displayed on the monitor in a layout that does not require the line of sight to be moved. Can be confirmed.
