A door limit switch SW1 is provided to detect the open / closed state of the front door 49.

FIG. 5 is a block diagram of the limit switches SW1 to SW6 arranged as described above. In the figure, each of the limit switches SW1 to SW6 is connected to the one-chip processor 202 after being converted into a signal having a processable voltage-current waveform via the regulator IC 201. On the other hand, the start switch 25 is also connected to the 1-chip processor 202. From this one-chip processor 202, three signal lines for instructing the forward / reverse rotation drive of the drive motor 33, a brake and a complete stop are connected, and each of them is connected to a brake terminal of a motor driver 204 via a photo coupler 203. 205, a forward / reverse rotation drive terminal 206, and a complete stop terminal 207.

With reference to FIG. 3 in the above configuration, when the main switch of the main body of the apparatus is turned on, the state of each limit switch is searched after the initialization of the one-chip processor 202, and the inclination angle is searched. When the base portion 6 of the variable device 1 is at the maximum tilt angle position as shown by the solid line (FIG. 3), this position state is the rear limit switch S.
It is detected that W3 is "on", and it is determined that it is in a normal state, and the drive motor 33 is not particularly driven.

On the other hand, when the base 6 of the tilt angle varying device 1 is at the minimum tilt angle position as shown by the broken line (FIG. 3), this position state is detected by the front limit switch SW4 being "on". Then, the drive motor 33 is determined to be in a normal state, and the drive motor 33 is not particularly driven.

On the other hand, when it is desired to move the tilt angle varying device 1 from the position shown by the solid line in FIG. 3 to the position shown by the broken line after the power is turned on, or from the position shown by the broken line to the position shown by the solid line. When desired, the start switch 25 is pressed to start the forward / reverse rotation of the drive motor 33, the rear limit switch SW3 is turned off, and then the front limit switch SW4 is turned on. Tilt angle position. Alternatively, when the front limit switch SW4 is turned off and the rear limit switch SW3 is turned on, the control program for performing drive control so as to move to the maximum tilt angle position is the one-chip processor 20 described above.
2 is written in advance.

When the tilt angle varying device 1 is at the intermediate position which is not located at the position shown by the solid line or the position shown by the broken line in FIG. It is necessary to drive the tilt angle varying device 1 to any position for initialization.

If the drive motor 33 is suddenly driven, it will be driven even if the door limit switch SW1 is in the "OFF" state and the front door 49 is open. Further, even if the guide stud 10 is disengaged from the guide groove 20, if the guide stud 10 is driven, it becomes impossible to prevent the lateral blurring regulation when the base portion 6 moves.

In such a case, motor drive control is performed according to the flowchart shown in FIG. In this figure, after the initialization when the power source of the apparatus is turned on, when it is started in step S1, it is determined in step S2 whether the door 49 is closed and the door limit switch SW1 is in the "on" state. If it is turned off and is "off", the process proceeds to step S8, the motor is not driven, and the process returns at step S13.

On the other hand, when the door limit switch SW1 is in the "on" state, the process proceeds to step S3, and subsequently it is judged whether or not the foot limit switch SW5 which becomes normal in the normally closed state is "on". If it is turned off, the process proceeds to step S8, the motor is not driven, and the process returns at step S13.

If it is determined in step S3 that the foot limit switch SW5 is "on", then it is determined in step S4 whether the front limit switch SW4 is "on". Since it is at the minimum tilt angle position, the process proceeds to step S8, the motor is not driven, and the process returns at step S13. Next, in step S5, the rear limit switch SW
It is determined whether or not 3 is "on". When it is "on", it is in the maximum tilt angle position retracted. Therefore, the process proceeds to step S8 so that the motor drive is not performed and step S1 is performed.
Return with 3.

On the other hand, when it is judged to be "OFF" in steps S4 and S5, the tilt angle varying device 1 is in the intermediate position which is not located at the position shown by the solid line or at the position shown by the broken line in FIG. It is determined that the motor is started in the clockwise direction in step S6, is continued until SW3 is turned on in step S7, and is stopped in the retracted position. As described above, the tilt angle varying device 1 is stopped at the home position shown by the solid line in FIG.
Return and end.

On the other hand, when the drive motor overruns for some reason and the base 6 moves beyond the above SW3, 4, as shown in the flow chart of FIG. The guide stud 10 provided further moves the actuator block 35 to turn on the back limit switch SW2 or the front limit switch SW6 for detecting overrun when the base 6 is moved forward (steps S21 and S25). In step S22, the drive motor 33 is forcibly stopped, abnormally stopped and an abnormal stop flag is set, and the subsequent processing is forcibly stopped. As described above, the driven drive motor 33 is a perfect countermeasure against runaway.

8A and 8B are side views showing an auxiliary mechanism at the time of starting the drive motor 33. FIG. 8A shows a state in which the base portion 6 is in an upright position, and FIG. 8B shows a state in an inclined position. It is a thing.

Since the weight of the base portion 6 is added from the state shown in FIG. 8A, the drive motor 33 does not generate much load, and rather acts as a motor brake in the final drive position. On the other hand, in the case of driving from the position shown by the broken line in FIG. 3 to the position shown by the solid line, when starting from the position shown in FIG. 8B, the drive motor 33 requires a starting torque of 100 kilograms F or more. Become.

Therefore, the support arm 28 is further extended downward from the lower fulcrum 30, and a hook portion 52 for locking one end of the tension coil spring 50 is provided, while being fixed to the apparatus main body. The hook portion 51 is fixed, and the tension coil spring 50 is stretched in the tension state of the entire length K. Further, a tension coil spring 50 (not shown) is stretched in a tensioned state with a total length K, and has a total length J in a natural state.

In the above structure, the maximum load when the base 6 of the tilt angle varying device is at the minimum tilt angle position in FIG. 8B is reduced by the pulling force of the tension coil spring 50, and the load on the drive motor 33 is reduced. So that
The size of the drive motor 33 can be reduced. Further, by arranging a plurality of tension coil springs 50 as tension means in parallel, a desired tension force can be obtained in a limited space.

Further, the end face 32c of the sector gear 32 is brought into contact with the stopper pin 54 fixed to the apparatus main body 2 at the rotating position shown in FIG.
A pin for restricting further rotation is provided, and a pure mechanical overrun prevention mechanism is provided for the above-mentioned motor control for overrun prevention.

Next, FIG. 9 shows how the projection 41 at the lower edge of the base 6 rides on the sloped portion 40 formed on the upper surface 22 when the base is guided and driven to the maximum inclination angle position. FIG. In this figure, as described above, the drive motor 33 is driven in the clockwise direction and the rear limit switch SW3 is turned “on”, and before and after the rear limit switch SW3 is turned on. 41 becomes a state of riding and stops.

By maintaining the state as described above, when moving as shown by the solid line, the upper part of the display surface 3a is touched by the touch force of F1 and the lower part is touched by the touch force of F2. In any case, help the weight W of the flat panel display 3 is around 15 kg,
It can be completely immobile.

On the other hand, in the case of the position shown by the broken line, the weight of the flat panel display 3 is irrespective of whether the upper part of the display surface 3a is touched by the touch force of F1 or the lower part is touched by the touch force of F2. Can be immobilized by.

Even if the present invention is applied to a system composed of a plurality of devices such as "a host computer, an interface, a printer", it is also applied to an apparatus composed of a single device such as "a copying machine". Is also good. Needless to say, the present invention can be applied to a case where the present invention is achieved by supplying a program to a system or an apparatus. In this case, the system or device enjoys the effects of the present invention by reading the program into the system or device from a storage medium storing a program represented by software for achieving the present invention.
