DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of the present invention will be described in more detail with reference to the embodiments shown in the drawings. FIG. 1 is a plan view showing an embodiment of a vehicle-mounted display device of the present invention in a state when the display is accommodated corresponding to FIG. The structure of the drive mechanism of this device is the same as that of the previous invention, and the appearance of this device is also the same as that shown in FIG. 5, Figure 6
The same reference numerals as in the above are given, and duplicate explanations are omitted.

In the present invention, the display 3 is provided with the solenoid lock mechanism 40. Figure 2 (a)
Shows the details of the solenoid lock mechanism 40, in which the final drive gear 37 of the second gear train 8 driven by the second motor 7 is provided with a plurality of holes 41 arranged in the circumferential direction. The solenoid 42 is provided with a fixing rod 43 that is inserted into and removed from the hole 41 by its drive. A position detection gear 44 is meshed with the drive gear 37 as shown in the side view of FIG. 1B, and a photo reflector 45 that projects light onto the side surface of the position detection gear 44, facing one side surface of the position detection gear 44.
Is installed.

FIG. 3 illustrates the control principle of the solenoid lock mechanism 40. The photo-reflector 45 projects light onto the position detection gear 44 and receives the reflected light to rotate the drive gear 37. (Therefore, the rotation angle of the display 3) is detected, and the detection pulse signal from the photo reflector 45 is input to the control microcomputer to control it.
The solenoid 42 is driven by a control signal from the microcomputer and the fixing rod 43 is inserted into the hole 41 of the drive gear 37 and locked to hold the display 3 at a desired angular position.

A plurality of holes 41 of the drive gear 37 are provided for each angle of the drive gear 37 to make a required rising angle (for example, 80 °, 90 °, 100 °, 110 °) with respect to the horizontal position of the display 3. , The fixing rod 43 of the solenoid 42 is inserted into one of these holes 41 to hold the angle of the display 3, but the angle is set (changed).
In this case, it goes without saying that the fixing rod 43 must be accurately inserted into the predetermined hole 41. The operation for this is performed as follows. FIG. 4 (a) shows the operating chart. That is, when the angle is changed, the solenoid 42 is pulled (the retracting direction of the rod 43), and then the motor 7 is rotated. When the input rotation pulse reaches the specified rotation (the number of rotations that is not affected by the variation due to the product), the solenoid 42 is set to the free position (the forward direction of the rod 43). After freeing, the motor 7 is continuously driven for about 1 second (depending on the timing of releasing the solenoid 42 and the timing at which the rod 43 can be surely inserted by driving the motor 7 thereafter).

The initial angle at the time of rising of the display 3 is a memory operation (memory of the number of pulses after the position detection gear 44 detects a reference angle, for example, 80 °) set to the angle set before storage. In order to surely set the memory position, an angle detecting sensor means (the photo reflector 44 or the mechanical SW in the above embodiment) for detecting the position of the reference angle 80 ° is provided, and the angle setting hole 4 is provided.
For the position of 1, the pulse count value is normalized so as to eliminate the problem caused by the accumulated error. This normalized count value takes into consideration variations due to products.

FIG. 4 (b) shows an operation chart when the display 3 rises from the horizontal position (0 °) to the reference angle 80 °.
At the same time, with the start of the rising operation of the motor 7, a pulse is generated at the same time. Angle detection sensor means 80 ° ON
(H → L) is detected, and the motor 7 is continuously driven for about 1 second beyond that so that the rod 43 of the solenoid 42 can be securely fitted and locked in the hole 41.

When the rising angle of the display 3 is set to 80 ° ⇔ 90 ° ⇔ 100 ° ⇔ 110 ° as described above, by operating the down button 14 and the up button 15, the motor 7 is kept at 10 ° during this period. To be able to rotate by feeling. FIG. 4 (c) is a chart of this 10-degree sensation, in which the rising or falling of the pulse is detected, and the solenoid 42 is freed at the third point. Solenoid 4
After setting 2 to free, the motor 7 is driven for 1 second. If the rod 43 of the solenoid 42 locks in the hole 41 within 1 second, the rotation by the motor 7 will slip for the remaining time.

In the above display rising angle determining operation, if the operation is normally performed, no trouble occurs, but the angular position is set to a predetermined value (80 by the pulling operation of the display during the angle determining operation).
(°, 90 °, 100 °, 110 °), the angle position may be 80 ° or less. In this case, since the rod 43 is not locked by the driving of the solenoid 42, the display 3 may fall due to vibration or the like. In order to avoid such inconvenience, in the present invention, the operation at 80 ° or more is constantly monitored by the angular position detecting means (the position detecting gear 44 and the photo reflector 45 in the above embodiment) for detecting the reference angular position 80 °. When the angular position is 80 ° or less, the motor 7 is rotated in the normal direction (rotated in the rising direction of the display 3) and the rod 43 of the solenoid 42 is raised by the control of the controller (control microcomputer). Angle 8
The driving gear 37 is locked by being fitted into the hole 41 of the drive gear 37 corresponding to 0 °.

In the above embodiment, the rotation of the position detecting gear 44 is detected by the photo reflector 45 as the position detecting means, but the rotation of the driving gear 37 itself may be detected by the photo reflector or the like. Further, as the 80 ° detecting means, the position of the drive gear 37, the arc gear 38, etc., which change in position depending on the rotation angle of the display 3, can be detected by a mechanical switch or another sensor.

Possible display, a first motor for driving the slide body, a second motor for driving the display
And a position detecting means for detecting a rotation angle of the display by driving the second motor, a solenoid lock mechanism for locking the rotation of the display, a position detecting means and a solenoid lock. Since a controller for controlling the mechanism is provided and the display is locked and locked at a predetermined set rotation angle, it is possible to automatically pull out, rise, fall and store the display with simple operations. In addition, the display can be reliably and accurately maintained at a desired rising angle during use.
