  The key operation unit 31 has a plurality of pressing keys, and is attached to a part of a dashboard that can be operated by a passenger in the front seat (FIG. 2). The key operation unit 31 notifies the central processing unit 32 of the operated key. As the key operation unit 31, a remote commander may be applied in addition to the one embedded in the dashboard.

  The pressure sensors 38A, 38B,..., 38X are provided in each seat of the vehicle 1, and detect the pressure applied to each seat and output the detection result. That is, the pressure sensors 38 </ b> A to 38 </ b> X are provided at a portion where the passenger in each seat sits so that the seating of the passenger in each seat can be detected based on the pressure detection result. Further, a predetermined number is provided on the backrest of each seat so that the seat height of the passenger seated on each seat can be detected based on the same pressure detection result.

  A ROM (Read Only Memory) 33 records and holds the processing program of the central processing unit 32, and further stores and holds in advance the optimum position of the monitor 3 with respect to the seating position of the passenger. Here, this optimum position is the position that is most easily seen from the seat on which the passenger is seated, within the movable range of the monitor 3 by the longitudinally movable mechanism 2, and when the passenger is seated on the front seat in the first row When seated in the second row of seats, each seat is provided for each seat in the third row of rear seats. Specifically, this optimal position is, for example, the front of the movable range when the passenger is seated in the front seat, and to the side of the backrest of the front seat when the passenger is seated in the second row of seats. It is a retracted position.

  In addition to this, the ROM 33 records and holds in advance the optimum height position of the monitor 3 with respect to the sitting height of the passenger. This height position is the position at which the monitor 3 is most easily viewed relative to the seat height of the passenger.

  Furthermore, the ROM 33 records and holds in advance the contrast adjustment value of the monitor 3 with respect to the seating position of the passenger. That is, as described above with reference to FIG. 2, the monitor 3 is hung from the ceiling and moved in the front-rear direction in the center of the vehicle, so that it sits in the center of the seat in the third row, for example. The passenger can see the monitor 3 from the front, while the passengers in the left and right seats see from an angle. The monitor 3 needs to adjust the contrast according to the viewing position because of the difference in the contrast of the image seen between when viewed from the front and when viewed from the diagonal. For this reason, in this embodiment, an optimum contrast is secured in each seat based on the contrast adjustment value.

The central processing unit 32 detects the seat on which the occupant is seated based on the detection result of the pressure sensor provided in the seat surface from the pressure detection results of the pressure sensors 38A to 38X, and is provided in the backrest. In addition, a rough seat height of a seated passenger is detected based on detection results of a plurality of pressure sensors.

  The central processing unit 32 also determines the position and height of the monitor 3 to be moved based on the seating position information of the occupant thus detected, the optimum position information of the monitor 3 held in the ROM 33, and the contrast adjustment value. And the contrast adjustment value of the monitor 3 is determined. In determining the position to which the monitor 3 should move, the central processing unit 32 can set the movement to the foremost part only when the vehicle 1 is stopped. This prevents the monitor 3 from moving to the forefront during traveling, and prevents the driver's field of view from being obstructed.

  Further, when the user instructs the use of the monitor 3, the central processing unit 32 sends a driving signal for moving the monitor 3 to the optimum position and height determined in this way to the front-rear direction movable mechanism 2 and drives it back and forth. The motor 11 and the vertical drive motor 19 are driven. As a result, the central processing unit 32 moves the monitor 3 to the optimum position according to the seating position of the passenger based on the seating position information of the passenger.

  The central processing unit 32 once adjusts the position of the monitor 3 to the optimum position as described above, by monitoring the pressure detection results by the pressure sensors 38A to 38X by the user's prior setting, Monitor changes. When a seat change by the passenger is detected, the position of the monitor 3 is readjusted to the optimum position. Further, when the use of the monitor 3 is detected by the operation of the operation unit 31, the monitor 3 is moved to the retracted position. Here, the retracted position is a position where the monitor 3 is lifted to the uppermost position and moved to the rearmost position.

  On the other hand, the central processing unit 32 switches the operation of the source 36 when the passenger is instructed to switch the source by operating the key operation unit 31.

  Here, the source 36 switches the operation under the control of the central processing unit 32, and the video data of the video content by television broadcasting, DVD (Digital Versatile Disc), etc. is sent to the monitor 3 via the central processing unit 32 and the interface 41. Output.
