It should be noted that FIGS. 2 to 12 show only the mechanical basic structure of the constituent elements used for the description of the present invention, and other constituent elements (for example, electric parts and the like) necessary for the audio equipment are omitted.

Using the guide rails (2) crimped on the upper case (1) as a guide, the slider (3) slides relative to the upper case (1) by an appropriate number of guide rollers (3a) provided on both sides. You can do it. Further, the slide base (4) can be slid with respect to the slider (3) by a suitable number of guide rollers (4a) provided on both sides.
The monitor (6) is fixed to a rotating plate A (26) rotatably attached to a rotating base (27) which is rotatably connected to a slide base (4) in a vertical direction through a tilt hinge (7). The monitor (6) can be manually started up and operated. A pinion (10) is incorporated in the slide base (4) through a gear train including a motor (8) and a torque clutch (9), and this pinion (10) is provided on a slider (3). It meshes with the rack (11). The crank gear (12) is rotatably supported by the slider (3), and a module gear having the same size as the rack (11) is formed on the outer periphery of the crank gear (12). The link (13) has one end rotatably supported by the shaft of the upper case (1) and the other end rotatably supported near the outer periphery of the crank gear (12). Lock plate (1
4) is a pair of lock plate shafts (1
5) It is provided so as to be able to move laterally, and spring pressure is applied to the right by the lock plate spring (16). The pair of lock plate shafts (15) are engaged with the pair of inverted J-shaped cam grooves (18) of the upper guide (17) screwed to the upper case (1). The lock plate actuating pin (19) provided on the slide base (4) is attached to the inclined cam portion (20) at the center of the lock plate (14) along with the ejection slide of the slide base (4) to 14) is moved to the left.

Further, the rotary base (27) is attached via a tilt hinge (7) attached to the slide base (4).
Is attached. The rotary plate A (26) is fitted into the lower side of the rotary base (27) through the sliding hole (30), the ball (25) is placed on the upper side, and the rotary plate C is placed thereon.
(29) is fixed, the rotary plate B (28) is mounted thereon, and the whole is fixed by screwing a screw into the central screw hole.
As a result, the rotary plate A (26) is pressed by the rotary plate C (29) and is rotated by 90 ° along the sliding hole (30).
It can be rotated. The start point and the end point are guided by the ball (25) into the hole of the rotating plate C (29) and have a click effect. The rotation plate A26 has three projections 2 for fixing the monitor on three places.
6a is formed, and the monitor (6) has the protrusion 26
It is fixed with a screw etc. so that the monitor screen is on the lower side of a. The micro switch (31) is attached so that it is turned on at one position and turned off at the other position when it is rotated 90 degrees in the cutout portion of the rotary plate B, and this on / off signal causes the vertical direction of the monitor (6). Determine the screen / horizontal screen position.

Next, the operation when the monitor is used in the above structure will be described. 1. First, before using the monitor, as shown in FIGS. 7 and 11, the monitor (6) is housed in the upper case (1). 2. Next, when the motor (8) rotates in the discharge direction by operating the operation button when using the monitor, the pinion gear (1
0) rotates clockwise, and the slide base (4) moves in the ejection direction with respect to the slider (3). 3. At this time, the lock plate shaft (15) of the lock plate (14)
Is in the tail portion (21) of the inverted J-shaped cam groove (18) of the upper guide (17), and the slider (3) is locked to the upper case (1). 4. The slide base (4) moves in the discharging direction, the pinion gear (10) finishes meshing with the rack (11) of the slider (3), and the lock plate operating pin (19) moves the inclined cam portion () of the lock plate (14). 20), the lock plate (14) is moved leftward, and the lock plate shaft (15) escapes from the tail portion (21) of the inverted J-shaped cam groove (18), and the upper case (1). And unlock the slider (3).

5. When a part of the slide base (4) hits the stopper portion (22) of the slider (3), the slide base (4) cannot move further in the ejecting direction with respect to the slider (3). 6. If the motor (8) continues to rotate in this state,
The pinion gear (10) causes the crank gear (12) to start rotating counterclockwise. 7. When the crank gear (12) rotates counterclockwise,
The slider (3) and the slide base (4) are integrated by the link (13) and slide-moves in the discharging direction with respect to the upper case (1). 8. When the slider (3) starts to slide in the discharge direction, the lock plate shaft (15) of the lock plate (14) causes the tail portion (2) of the inverted J-shaped cam groove (18) of the upper guide (17).
1) to the straight portion (23), that is, the lock plate (14) further moves to the left, and the lock actuating pin (19) of the slide base (4) moves to the horizontal cam portion () of the lock plate (14). 24) and the slider (3) and slide base (4) are locked.

9. The slider (3) and the slide base (4) move forward until the crank gear (12) hits the rotation stopper, the discharge detection switch (not shown) is turned on at that position, and the motor pulse detector (for example, A photo interrupter provided at the position of the gear train) is activated to detect the rotation of the motor (8), and the rotation of the motor (8) is stopped when the rotation of the motor (8) is detected for a predetermined number of times. Controlled as. As a result, the monitor (6), as shown in FIG.
It stays in the position where it is maximally discharged outside the upper case (1). 10. Then, when the monitor (6) is grasped by hand and a force for rotating in the vertical direction is given, the rotary base (27) is rotated in the vertical direction by the tilt hinge (27), and the monitor (6) is rotated.
Is the position where the monitor screen can be seen as a vertical screen. The rotation angle in the vertical direction can be stopped in any angle range,
It is preferably 90 degrees. 11. If you want to view the monitor (6) in the horizontal screen, you can grab the monitor (6) from the position on the vertical screen and apply a force to rotate it in the horizontal direction. Rotate to and click stop at the 90 degree position.

As described above, the large-screen monitor, which has been conventionally considered unfittable, can be housed by putting it up vertically and then rotating it horizontally. In addition to the conventional one-way screen (horizontal screen), it is also possible to view the screen rotated 90 ° (vertical screen).

[0015]

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made. For example, it is easy to change the operation method without changing the basic structure. That is, a vehicle with a right handle can be configured to rotate the monitor unit 90 ° to the left, and a vehicle with a left handle can be configured to rotate 90 ° to the right. (This is desirable in view of the viewing angle of the liquid crystal display. It is an example of the configuration when the driver's side is taken into consideration.)
Any mechanism (slider, slide base, rotating plate, etc.) for ejecting, vertically rotating and horizontally rotating the monitor can be configured to be manually or electrically operated.

[0016]

According to the present invention, it is possible to store a monitor with a larger screen than in the past by rotating a large-screen monitor, which has been conventionally impossible to be stored, vertically and then horizontally.
