The traveling gear 32 is attached to both ends of the rotating shaft 31 and rotates integrally with the rotating shaft 31. The traveling gear 32 meshes with the rack 30. The plurality of gears 33 mesh with each other. One of the plurality of gears 33 meshes with the worm 34, and the other meshes with the gear 50 provided on the rotating shaft 31. Therefore, the plurality of gears 33 transmits the rotational driving force of the motor 29 to the traveling gear 32.

  With the configuration described above, in the transfer unit 19, when the motor 29 is driven in the normal direction, for example, the traveling gear 32 travels on the rack 30, and the housing position where the slide chassis 16, that is, the display unit 3 is housed in the housing 2. The display unit 3 is moved along the depth direction Y of the housing 2 toward the exposed position (shown in FIG. 11) discharged from the housing 2 (shown in FIG. 10). That is, the transfer unit 19 exposes the display unit 3 in the housing 2 to the outside of the housing 2 through the opening 2a when the motor 29 is driven in the normal direction, for example.

  Further, in the transfer unit 19, when the motor 29 is driven in the reverse direction, for example, the traveling gear 32 travels on the rack 30, and the slide chassis 16, that is, the display unit 3 is moved from the above-mentioned exposed position to the accommodation position toward the housing 2. Moves along the depth direction Y of. That is, the transfer unit 19 stores the display unit 3 outside the housing 2 in the housing 2 through the opening 2a when the motor 29 is driven in the reverse direction, for example. In this way, the transfer unit 19 covers the display unit 3, the rotation chassis 17, the slide chassis 16, and the displacement unit 20 over the housing position housed in the housing 2 and the exposed position discharged from the housing 2. And the rotary moving unit 21 and the rotary support 18 are moved integrally.

The motor 35 is attached to the slide chassis 16, and the worm 40 is attached to the output shaft.

  The rotating shaft 36 is rotatably supported at the end of the slide chassis 16 near the opening 2a. The longitudinal direction of the rotating shaft 36 is parallel to the width direction X of the housing 2. The transmission gears 37 are attached to both ends of the rotary shaft 36 and rotate integrally with the rotary shaft 36. The fixed gears 38 are fixed to both ends of the casing 2 of the rotating chassis 17 in the width direction X. Each of the fixed gears 38 meshes with the above-described transmission gear 37 via the gear 37a.

  The plurality of gears 39 mesh with each other. One of the plurality of gears 39 meshes with the worm 40, and the other one meshes with the one transmission gear 37. Therefore, the plurality of gears 39 transmits the rotational driving force of the motor 35 to the transmission gear 37.

  With the configuration described above, in the displacement unit 20, when the motor 35 is driven to rotate normally, the transmission gear 37 rotates and the fixed gear 38 rotates. Then, since the fixed gear 38 is fixed to the rotating chassis 17, the display unit 3 is discharged from the inside of the housing 2, that is, moved from the storage position to the display position (shown in FIG. 4). 3a faces the occupant in the passenger compartment, etc., toward the visual recognition position shown in FIG. 5, and the rotating chassis 17, that is, the display unit 3 with the one end portion 3c located on the back side of the housing 2 of the display unit 3 as a center. The housing 2 is rotated around the width direction X. That is, the displacement unit 20 makes the display unit 3 stand up.

  Further, in the displacement unit 20, when the motor 35 is driven in the reverse direction, for example, the transmission gear 37 rotates and the fixed gear 38 rotates. Then, since the fixed gear 38 is fixed to the rotating chassis 17, the rotating chassis 17 moves toward the visible position shown in FIG. 8 where the display panel 3a faces the occupant in the passenger compartment from the above-described exposed position. The display unit 3 is rotated around the width direction X of the housing 2 around the one end 3c of the display unit 3 located on the inner side of the housing 2. That is, the displacement unit 20 lowers the display unit 3. In this way, the displacement unit 20 raises or lowers the display unit 3, moves from the storage position to an exposed position, and a visible position where the occupant visually recognizes the information displayed on the display panel 3a. The display unit 3, the rotating chassis 17, the rotation moving unit 21, and the rotation supporting portion 18 are integrally displaced.

  As shown in FIGS. 10 to 12, the rotary movement unit 21 includes a motor 41 as a drive source, a support gear 42, and a plurality of gears 43. The motor 41 is attached to the rotating chassis 17, and a worm 44 is attached to the output shaft.

  The support gear 42 is fixed to the support 27 described above, and is arranged coaxially with the support 27. The plurality of gears 43 mesh with each other. One of the plurality of gears 43 meshes with the worm 44, and the other meshes with the column gear 42. Therefore, the plurality of gears 43 transmits the rotational driving force of the motor 41 to the support gear 42.

  With the configuration described above, when the motor 41 is driven to rotate in the normal direction, the rotary movement unit 21 rotates the support gear 42 to rotate the display unit 3 clockwise in the arrow K around the axis P described above. The rotation of the display unit 3 in the clockwise direction is referred to as the rotation of the display unit 3 to the right.

  When the motor 41 is driven in the reverse direction, the rotation moving unit 21 rotates the support gear 42 and rotates the display unit 3 counterclockwise in the arrow K around the axis P described above. The rotation of the display unit 3 in the counterclockwise direction is referred to as the rotation of the display unit 3 to the left. In this way, the rotation moving unit 21 can rotate the display unit 3 in the bidirectional K around the axis P parallel to the display panel 3a.

  As shown in FIGS. 13 and 14, the pair of detection switches 5 a and 5 b includes a main body portion 45 and a contact portion 46 that can project and retract from the main body portion 45. The main body 45 is fixed to the rotating chassis 17. The contact portion 46 faces the display unit 3. The contact portion 46 abuts on the protrusions 12 a and 12 b, so that the contact portion 46 is pressed by the protrusions 12 a and 12 b and is sunk in the main body portion 45. The pair of detection switches 5a and 5b are turned on when the contact portion 46 is submerged in the body portion 45, and output information indicating that the contact portion 46 is turned on to the CPU 8.

  The pair of detection switches 5a and 5b are arranged along the width direction X of the housing 2, as shown in FIGS. The distance between the one detection switch 5a and the axis P is equal to the distance between the one protrusion 12a and the axis P. The distance between the other detection switch 5b and the axis P is equal to the distance between the other protrusion 12b and the axis P. For this reason, in the pair of detection switches 5a and 5b, when the display panel 3a faces upward or downward, one of the contact portions 46 is pressed by the protrusions 12a and 12b and is sunk in the main body portion 45.

  In this way, in the pair of detection switches 5a and 5b, the display panel 3a of the display unit 3 at the exposed position is located above because the contact portion 46 of either one of the detection switches 5a and 5b is retracted into the body portion 45 by the protrusions 12a and 12b. It detects that it is facing to one of the lower parts. Then, the pair of detection sensors 5a and 5b output information indicating that one of them is turned on to the CPU 8 to thereby indicate that the display panel 3a is facing either upward or downward. Is output to the CPU 8.

  In the illustrated example, when the display panel 3a faces downward as shown in FIGS. 10 and 11, as shown in FIG. 13, of the pair of detection switches 5a and 5b in the width direction of the housing 2. The projection 12a comes into contact with the contact portion 46 of the one detection switch 5a located outside along the X, and the one detection switch 5a is turned on. When the display panel 3a faces upward as shown in FIG. 12, the pair of detection switches 5a and 5b are positioned inside in the width direction X of the housing 2 as shown in FIG. The protrusion 12b comes into contact with the contact portion 46 of the other detection switch 5b, and the other detection switch 5b is turned on.

  The ROM 6 stores a program for operating the car navigation system 1 and the like. The ROM 6 stores a program for operating the CPU 8 as described later.

  The EPROM 7 is a well-known non-volatile memory, and is used for the output shafts of the motors 29, 35, 41 from the time when the display unit 3 is once discharged to the outside of the housing 2 until the display unit 3 is housed inside the housing 2 again. The rotation direction and the rotation speed are written by the CPU 8. The EPROM 7 rotates in the rotation direction when the display unit 3 is rotated around the axis P at the visual recognition position while the display unit 3 is once ejected from the housing 2 and then the display unit 3 is housed in the housing 2 again. And the number of rotations are written by the CPU 8.

  The EPROM 7 stores the rotation direction and the rotation speed until the display unit 3 is once discharged from the housing 2 until the display unit 3 is housed in the housing 2 again. The rotation direction and the rotation number are oriented around the axis P of the display unit 3 at the visually exposed position described in this specification. The EPROM 7 may store an arbitrary rotation direction and rotation number input from the operation unit 13 or the like as the orientation of the display unit 3 around the axis P at the visual recognition position.

  The CPU 8 serves as the control means, the determination means, the instruction means, and the second instruction means described in this specification, and as shown in FIG. 15, the navigation unit 9, the DVD player 10, and the television. The tuner 11, the motors 29, 35, 41 of the drive mechanism 4 described above, the detection switches 5a, 5b, the ROM 6, the EPROM 7, etc. are connected, and by controlling these, the overall control of the car navigation system 1 is performed. Control

  When the CPU 8 receives a command to eject the display unit 3 out of the housing 2 and position it at the visual recognition position from the operation button 14 of the operation unit 13 in a state where the display unit 3 is housed in the housing 2, the CPU 8 drives the motor. 29, the display unit 3 is driven in the normal direction to move the display unit 3 through the opening 2a along the depth direction of the casing 2 together with the rotation chassis 17, the slide chassis 16, the rotation support portion 18, the displacement unit 20, and the rotation movement unit 21. , Is gradually discharged to the outside of the housing 2. Then, the CPU 8 stops the motor 29 when the predetermined rotation number motor 29 stored in advance in the ROM 6 is driven to rotate normally.

  Then, the CPU 8 determines whether or not any one of the pair of detection switches 5a and 5b is ON after a predetermined time has elapsed after stopping the motor 29 of the transfer unit 19, It is determined whether the display panel 3a of the display unit 3 is facing upward or downward. Then, the CPU 8 drives the motor 35 in the normal direction or in the reverse direction so that the display panel 3a faces the occupant to raise or lower the display unit 3.

  As described above, the CPU 8 moves the display unit 3 from the storage position to the exposed position by the transfer unit 19 and then, after a predetermined time elapses, the direction in which the display panels 3a detected by the detection switches 5a and 5b face each other (that is, the opposite direction). , The displacement unit 20 is controlled according to the detection result. The CPU 8 causes the displacement unit 20 to displace the display unit 3 from the exposed position toward the visible position.

  The occupant of the vehicle described above may rotate the display unit 3 around the axis P to change the direction in which the display panels 3a face each other during a predetermined time. Therefore, it is desirable that the predetermined time is a time in which the occupant can rotate the display unit 3 around the axis P and change the direction in which the display panel 3a faces. Then, the CPU 8 stops the motor 35 when the predetermined rotation speed motor 35 stored in advance in the ROM 6 is driven in the forward or reverse direction.

  After stopping the motor 35 of the displacement unit 20, the CPU 8 reads from the EPROM 7 the rotation direction and the rotation speed of the motor 41 that rotates the display unit 3 around the axis P at the visual recognition position stored in the EPROM 7. Then, the CPU 8 drives the motor 41 in the normal rotation or the reverse rotation based on the rotation direction and the rotation speed stored in the EPROM 7 (as it is) to rotate the display unit 3 around the axis P.

  In this way, the CPU 8 controls the rotational movement unit 21 according to the orientation of the display unit 3 stored in the EPROM 7 after the display unit 3 is positioned at the visual recognition position by the displacement unit 20 to move the display unit 3 to the axis P. Rotate around. Then, the CPU 8 stops the motor 41 when the predetermined rotation speed motor 41 stored in advance in the EPROM 7 is driven in forward or reverse rotation.

  Further, the CPU 8 rotates the motor 41 and changes the orientation of the display unit 3 in accordance with the instruction from the operation button 14 of the operation unit 13 described above. In this way, the CPU 8 positions the display unit 3 at the visual recognition position and changes the orientation of the display unit 3. Further, the CPU 8 appropriately changes the information displayed on the display panel 3a of the display unit 3 among the information from the navigation unit 9, the DVD player 10 and the television tuner 11 in accordance with a command from the operation button 14.

  The CPU 8 inputs a command to store the display unit 3 in the housing 2 (command to move to the storage position) from the operation button 14 of the operation unit 13 or the like while the display unit 3 is positioned at the visual recognition position. There is. Then, the CPU 8 reads the rotation direction and the rotation speed of the motor 41 of the rotary movement unit 21 from the information stored in the EPROM 7. Then, the CPU 8 determines whether or not the display unit 3 has an angle (direction) around the axis P when the display unit 3 is positioned from the exposure position to the visual recognition position by the displacement unit 20, that is, when the display unit 3 is positioned at the exposure position by the transfer unit 19. To determine.

  Then, the CPU 8 determines that the angle (direction) around the axis P when the display unit 3 is positioned from the exposure position to the visual recognition position by the displacement unit 20, that is, when the display unit 3 is positioned at the exposure position by the transfer unit 19 is different. Then, the rotation direction and the number of rotations of the motor 41, which becomes the angle (direction) around the axis P when positioned at the above-mentioned visual recognition position, are calculated. Then, the CPU 8 rotates the motor 41 according to the calculated rotation direction and rotation speed (as it is).

  In this way, when the CPU 8 determines that the orientation of the display unit 3 is different from the orientation when the displacement unit 20 positions the visual recognition position, the display unit 3 is oriented in the orientation when the displacement unit 20 positions the visual recognition position. Rotate. in this way. While the CPU 8 is driving the motor 41, the EPROM 7 stores the rotation direction and the rotation speed of the motor 41.

  The CPU 8 stops the motor 41 when the calculated rotation direction and the rotation speed motor 41 are driven in the normal direction or the reverse direction. When the CPU 8 determines that the display unit 3 is at the angle (direction) around the axis P when the display unit 3 is positioned from the exposure position to the visual recognition position by the displacement unit 20, that is, when it is positioned at the exposure position by the transfer unit 19. When the calculated rotation direction and rotation speed motor 41 are driven, the rotation direction and rotation speed of the motor 35 of the displacement unit 20 are read from the information stored in the EPROM 7.

  Then, the CPU 8 drives the motor 35 of the displacement unit 20 at the same rotation speed in the opposite direction of the information stored in the EPROM 7. Then, it is determined whether or not the display unit 3 is rotated around the one end portion 3c when the display unit 3 is positioned from the housed position to the exposed position by the transfer unit 19. The CPU 8 drives the motor 35 of the above-described displacement unit 20 until the display unit 3 is oriented around the one end 3c when the display unit 3 is positioned from the housed position to the exposed position by the transfer unit 19. Thus, when the display unit 3 is housed in the housing 2 in the displacement unit 20 and the transfer unit 19, the CPU 8 first causes the displacement unit 20 to position the display unit 3 at the exposed position.

  The CPU 8 determines that the display unit 3 is oriented around the one end portion 3c when the transfer unit 19 is positioned from the storage position to the exposure position, that is, when the displacement unit 20 positions the display unit 3 at the exposure position. Then, the motor 29 of the transfer unit 19 is reversely driven to move the display unit 3 from the exposed position toward the accommodation position, and the display unit 3 is accommodated in the housing 2.

  Thus, the CPU 8 determines that the display unit 3 is at an angle (orientation) around the axis P when the display unit 3 is positioned at the visual recognition position by the displacement unit 20, and the axis when the display unit 3 is positioned at the exposure position by the displacement unit 20. When the angle (direction) around the center P is reached, the displacement unit 20 and the transfer unit 19 store the display unit 3 in the housing 2.

  Next, the operation of the car navigation system 1 as the display device having the above-described configuration will be described. As shown in FIG. 2, when the display unit 3 is housed in the housing 2 (that is, the display unit 3 is positioned at the housing position), when the display unit 3 is discharged to the outside of the housing 2. First, in step S1 in FIG. 16, the CPU 8 performs an operation for ejecting the display unit 3 out of the housing 2 (for pulling out) of the operation buttons 14, that is, an operation for positioning the display unit 3 at the visual recognition position. It is determined whether the button 14 has been operated. The CPU 8 repeats step S1 until the operation button 14 for pulling out the display unit 3 is operated, and when the operation button 14 for pulling out the display unit 3 is operated, the process proceeds to step S2.

  In step S2, the CPU 8 drives the motor 29 of the transfer unit 19 in the normal direction to gradually eject the display unit 3 to the outside of the housing 2 through the opening 2a, as shown in FIG. Then, the process proceeds to step S3. In step S3, the CPU 8 determines whether or not the transfer unit 19 stored in advance in the ROM 6 has a predetermined rotation speed of the motor 29 for positioning the display unit 3 from the accommodation position to the exposure position. judge.

  Thus, in step S3, the CPU 8 determines whether or not the display unit 3 is positioned at the exposure position, that is, whether or not the pulling out of the display unit 3 from the housing 2 is completed. Then, in step S3, step S3 is repeated until the motor 29 rotates a predetermined number of revolutions, that is, until the display unit 3 is pulled out from the housing 2, and the motor 29 rotates a predetermined number of revolutions. When the pulling out of the display unit 3 from the inside of the housing 2 is completed and the display unit 3 is positioned at the exposed position as shown in FIG. 4, the process proceeds to step S4.

  In step S4, the CPU 8 determines whether or not a predetermined time has elapsed since the display unit 3 was positioned at the exposure position after the motor 29 rotated a predetermined number of revolutions. Step S4 is repeated until the predetermined time has elapsed, and when the predetermined time has elapsed, the process proceeds to step S5.

  In step S5, the CPU 8 determines from the information from the pair of detection sensors 5a and 5b whether the display panel 3a faces upward as shown in FIG. When it is determined that the display panel 3a faces upward as shown in FIG. 7, the process proceeds to step S8, and when it is determined that the display panel 3a does not face upward, that is, it faces downward as shown in FIG. 4, the process proceeds to step S6. ..

  In step S6, the CPU 8 drives the motor 35 of the displacement unit 20 in the normal direction, and proceeds to step S7. In step S7, the CPU 8 determines whether the displacement unit 20 stored in advance in the ROM 6 has a predetermined rotation speed of the motor 35 for positioning the display unit 3 from the exposed position to the visual recognition position. judge. Thus, in step S7, the CPU 8 determines whether or not the display unit 3 has been positioned at the visual recognition position, that is, whether or not the display unit 3 has been started up.

  Then, in step S7, step S7 is repeated until the display unit 3 is started up until the motor 35 rotates a predetermined number of revolutions. When the display unit 3 is started up when the motor 35 rotates a predetermined number of rotations, the display unit 3 rotates from the exposed position around the one end portion 3c, and as shown in FIG. Located in. Then, the process proceeds to step S10 shown in FIG.

  In step S8, the CPU 8 reversely drives the motor 35 of the displacement unit 20, and proceeds to step S9. In step S9, the CPU 8 determines whether or not the motor 35 of the displacement unit 20 has rotated a predetermined number of rotations of the motor 35, which is stored in the ROM 6 in advance and positions the display unit 3 from the exposed position to the visual recognition position. To determine. Thus, in step S9, the CPU 8 determines whether or not the display unit 3 is positioned at the visual recognition position, that is, whether or not the display unit 3 is lowered.

  Then, in step S9, step S9 is repeated until the display unit 3 is lowered until the motor 35 rotates a predetermined number of revolutions. When the display unit 3 is lowered when the motor 35 rotates a predetermined number of rotations, the display unit 3 is rotated from the exposed position around the one end 3c, and is lowered to the visible position as shown in FIG. Located in. Then, the process proceeds to step S10 shown in FIG.

  Further, after the display unit 3 is positioned at the exposure position by the transfer unit 19 in step S4 described above and before a predetermined time elapses, the display unit 3 is indicated by the arrow K with the axis P in FIG. 4 as the center. You may rotate along and may change the direction which the display panel 3a of the display unit 3 faces.

  In step S10, the CPU 8 reads the rotation direction and the rotation angle around the axis P of the display unit 3 at the previous visual recognition position from the EPROM 7. Then, the CPU 8 determines whether the read rotation direction around the axis P of the display unit 3 is the right direction described above. If it is determined to be rightward, the process proceeds to step S11. If it is determined to be leftward rather than rightward, the process proceeds to step S12.

  In step S11, the CPU 8 drives the motor 41 of the rotary movement unit 21 in the normal direction, and proceeds to step S13. In step S13, the CPU 8 determines whether the motor 41 has rotated the number of rotations corresponding to the rotation angle read from the EPROM 7. The CPU 8 repeats step S13 until the motor 41 rotates the number of rotations corresponding to the rotation angle read from the EPROM 7, and when the motor 41 rotates the number of rotations corresponding to the rotation angle read from the EPROM 7, stops the motor 41. In this way, the display unit 3 rotates around the axis P at the visual recognition position as shown by the chain double-dashed line in FIGS. 6 and 9 and faces the direction stored in the EPROM 7 described above.

  Further, in step S12, the CPU 8 reversely drives the motor 41 of the rotary movement unit 21, and proceeds to step S14. In step S14, the CPU 8 determines whether or not the motor 41 has rotated the number of rotations corresponding to the rotation angle read from the EPROM 7. The CPU 8 repeats step S14 until the motor 41 rotates the number of rotations corresponding to the rotation angle read from the EPROM 7, and stops the motor 41 when the motor 41 rotates the number of rotations corresponding to the rotation angle read from the EPROM 7. In this way, the display unit 3 rotates around the axis P at the visual recognition position as shown by the chain double-dashed line in FIGS. 6 and 9 and faces the direction stored in the EPROM 7 described above.

  As shown in FIGS. 6 and 9, when the car navigation system 1 is positioned at the visual recognition position, the car navigation system 1 displays the navigation unit 9, the DVD player 10, and the television tuner 11 on the display panel 3a of the display unit 3 in accordance with a command from the operation button 14. Display information from. When the car navigation system 1 is positioned at the visual recognition position, the car navigation system 1 appropriately changes the orientation around the axis P of the display panel 3a of the display unit 3 according to a command from the operation button 14.

  Further, as described above, when housing the display unit 3 located at the visual recognition position in the housing 2, first of all, the operation button 14 for housing the display unit 3 in the housing 2 among the operation buttons 14. To operate. Then, in step S20 in FIG. 18, the CPU 8 reads the rotation direction and the rotation speed of the motor 41 of the rotary movement unit 21 from the information in the EPROM 7.

  Then, the CPU 8 determines whether or not the orientation around the axis P of the display unit 3 is the orientation when the displacement unit 20 positions the display unit 3 from the exposure position to the visual recognition position. That is, in step S20, the CPU 8 determines whether or not the display unit 3 is in a so-called swinging state. If the CPU 8 determines that the display unit 3 is not in the swinging state, that is, the orientation around the axis P of the display unit 3 is the orientation at the time of being positioned from the exposed position to the visual recognition position, the process proceeds to step S23. When the CPU 8 determines that the display unit 3 is in the swinging state, that is, the direction around the axis P of the display unit 3 is different from the direction when the display unit 3 is positioned from the exposed position to the visual recognition position, the process proceeds to step S21.

  In step S21, the CPU 8 sets the rotation direction and the rotation speed of the motor 41 of the rotation moving unit 21 that is the direction around the axis P of the display unit 3 when the displacement unit 20 positions it from the exposed position to the visible position. calculate. Then, the CPU 8 rotates the calculated rotational speed of the motor 41 in the calculated rotational direction, and proceeds to step S22. In step S22, it is determined whether or not the rotational speed calculated by the motor 41 has rotated in the calculated rotational direction. The step S22 is repeated until the rotation speed calculated by the motor 41 is rotated, and when the rotation speed calculated by the motor 41 is rotated, the processing proceeds to step S23. Thus, in step S22, the CPU 8 determines whether or not the orientation around the axis P of the display unit 3 has returned to the orientation at the time when the displacement unit 20 positions it from the exposed position to the visual recognition position.

  In step S23, the CPU 8 reads the rotational direction and the rotational speed of the motor 35 of the displacement unit 20 when the display unit 3 is displaced from the exposed position to the visual recognition position, based on the information in the EPROM 7. Then, the CPU 8 drives the read rotation speed motor 35 in the opposite direction to the read rotation direction. Then, the process proceeds to step S24.

  In step S24, the CPU 8 determines whether or not the rotation speed read by the motor 35 is opposite to the rotation direction read by the motor 35, and the rotation speed is read by the motor 35 in the opposite direction. When S24 is repeated and the motor 35 has rotated the number of rotations read in the opposite direction to the direction of rotation read by the motor 35, the process proceeds to step S25. Thus, in step S24, the CPU 8 determines whether or not the display unit 3 is in the exposed position and is oriented from the accommodation position by the transfer unit 19, that is, whether or not the display unit 3 is in the horizontal position. ..

  In step S25, the CPU 8 reads the rotation speed of the motor 29 of the transfer unit 19 when the display unit 3 is moved from the accommodation position to the exposure position based on the information in the EPROM 7. Then, the CPU 8 drives the motor 29 to read out the rotational speed in the reverse direction. In this way, the CPU 8 stores the display unit 3 in the housing 2, that is, moves the display unit 3 from the exposed position to the stored position.

  According to this embodiment, the display unit 3 is rotatably provided in the bidirectional direction K around the axis P parallel to the display panel 3a at the exposed position. Therefore, the display unit 3 can be housed in the housing 2 both in a state where the display panel 3a faces in one direction such as upward and in a state where the display panel 3a faces in another direction such as downward.

  Further, the CPU 8 rotates the display unit 3 from the exposed position toward the visual recognition position so that the display panel 3a faces the occupant or the like according to the direction in which the display panel 3a detected by the detection switches 5a and 5b faces. . Therefore, after the display unit 3 is once discharged to the outside of the housing 2, the display unit 3 is rotated both in a direction in which the display panel 3a rises upward and in a direction in which it falls downward. Therefore, depending on the mounting position on the instrument panel D and various operation parts provided on the instrument panel D, it is determined whether the above-mentioned display unit 3 is once discharged to the outside of the housing 2 and then is raised or lowered. You can choose.

  That is, the display panel 3a can be made to face an occupant or the like so that the operation unit and the like of the instrument panel D are not hidden by the display unit 3. Therefore, when the display panel 3a displays information, it is possible to prevent the display unit 3 from hiding various operation units provided in the instrument panel D.

  Further, the CPU 8 rotates the display unit 3 from the exposed position toward the visual recognition position so that the display panel 3a faces an occupant or the like according to the direction in which the display panel 3a detected by the detection switches 5a and 5b faces. Therefore, when the operation of ejecting the display unit 3 from the housing 2 is performed, the display unit 3 rotates so that the display panel 3a surely faces the occupant. Therefore, the occupant can reliably view the information displayed on the display panel 3a. Further, when ejecting the display unit 3 from the housing 2, no trouble is required to adjust (change) the orientation of the display unit 3.

  After a predetermined time elapses after the display unit 3 is discharged from the housing 2, the CPU 8 controls the display panel 3a to face the occupant or the like according to the direction in which the display panel 3a detected by the detection switches 5a and 5b faces. Rotate the display unit 3. Therefore, the direction in which the display panel 3a faces can be adjusted (changed) within a predetermined time, and whether the display unit 3 described above is once discharged to the outside of the housing 2 and then raised upward or lowered downward is ensured. Can be selected.

  Therefore, the display panel 3a can be made to face the occupant or the like so that the operation unit of the instrument panel D is not hidden by the display unit 3. Therefore, when the display panel 3a displays information, it is possible to reliably prevent the display unit 3 from hiding various operation units provided in the instrument panel D.

  According to the orientation of the display unit 3 stored in the EPROM 7 (as it is), the display unit 3 is rotated around the axis P at the visual recognition position. Therefore, when the operation of ejecting the display unit 3 from the housing 2 is performed, the display unit 3 can be rotated so that the display panel 3a surely faces the occupant. Therefore, the occupant can reliably view the information displayed on the display panel 3a of the display unit 3.

  Unless the display unit 3 at the visual recognition position is oriented around the axis P positioned at the visual recognition position by the displacement unit 20, the displacement unit 20 and the transfer unit 19 do not house the display unit 3 in the housing 2.

  Therefore, the display unit 3 is not housed in the housing 2 unless the display unit 3 is housed in the housing 2. Therefore, since the display unit 3 that cannot be housed in the housing 2 is not stored in the housing 2, the display unit 3 that cannot be housed in the housing 2 is forcibly stored in the housing 2. It is possible to prevent the display unit 3 and the like from being unexpectedly damaged.

  When the CPU 8 causes the displacement unit 20 and the transfer unit 19 to store the display unit 3 in the housing 2, first, the displacement unit 20 positions the display unit 3 at the exposed position. Then, the transfer unit 19 positions the display unit 3 at the accommodation position, that is, the display unit 3 is accommodated in the housing 2. As described above, since the display unit 3 is housed in the housing 2 after being positioned at the exposed position, the display unit 3 that cannot be housed in the housing 2 is not housed in the housing 2. Therefore, it is possible to reliably prevent the display unit 3 and the like from being abruptly damaged when the display unit 3 that cannot be accommodated in the housing 2 is forcibly accommodated in the housing 2.

  In the above-described embodiment, the rotation direction and the number of rotations of the motors 29, 35, 41 from when the display unit 3 is once discharged from the housing 2 to when the display unit 3 is housed in the housing 2 are written in the EPROM 7. When the display unit 3 is housed in the housing 2, the motors 29, 35, 41 are controlled based on the written rotation directions and rotation speeds of the motors 29, 35, 41. However, in the present invention, for example, a detection unit such as a rotary encoder for detecting the rotation direction and the rotation speed of each motor 29, 35, 41 is provided, and the housing 2 is provided in the housing 2 based on the information detected by the rotary encoder. The motors 29, 35, 41 may be controlled when the display unit 3 is housed.

  Further, in the present invention, the display unit 3 may be provided with, for example, a switch that is turned on when the display unit 3 is positioned at the visible position and the exposed position. The motors 29, 35, 41 may be controlled when the display unit 3 is housed in the housing 2 based on the information from these switches and the detection switches 5a, 5b described above.

  Furthermore, LD and PD may be provided so that the PD (Photodiode) receives laser light from, for example, an LD (Laser Diode) when the display unit 3 is positioned at the visual recognition position and the exposure position. The motors 29, 35, 41 may be controlled when the display unit 3 is housed in the housing 2 based on the information from the LDs, PDs and the detection switches 5a, 5b described above.

  Further, when the rotary encoder, the switch, the LD, the PD, and the like described above are provided and the means for directly detecting the direction of the display unit 3 is provided, an occupant or the like may be particularly provided without providing the rotational movement unit 21 described above. The display unit 3 may be rotated around the axis P by hand.
