Simultaneously, distance detecting sensor 77 is connected in moving body 71, is connected in the bight of display 71b particularly.This distance detecting sensor 77 prevents that to the distance of fixed body 74 or wall display 71b from during turning colliding wall by detecting display.In addition, as what notice in the description of first embodiment of Fig. 1, the drive division that is connected in first to the 3rd arm 72a, 72b, 72c is used to drive first to the 3rd arm 72a, 72b, 72c.
Method of operating according to the display rotating apparatus 70 of this embodiment is described below.When input makes about display 71b the instruction of rotating up and down, be connected in the drive division running of first to the 3rd arm 72a, 72b, 72c, so that first to the 3rd arm 72a, 72b, 72c turn over predetermined amount of spin.Therefore, display 71b is rotated the required angle of beholder.In addition, by the distance detecting sensor 77 real-time distances that detect between wall and the display 71b.Under the situation of the too close wall of display 71b,, can obtain the safe distance between wall and the display 71b by making arm elongation near position of collision.
Fig. 8 is the skeleton view according to the display rotating apparatus of fourth embodiment of the invention.In this embodiment, moving body 81 rotates by four arm 82a, 82b, 82c, 82d.
Describe the rotating method of the display rotating apparatus among the embodiment of Fig. 7 below in detail.
Fig. 9 is the process flow diagram of driving according to the method for the display rotating apparatus of fifth embodiment of the invention.The driving method of this embodiment (with reference to the display rotating apparatus among Fig. 7) is as described below.In Fig. 7, display rotating apparatus 70 comprises first to the 3rd arm 72a, 72b, 72c, but the embodiment corresponding with the process flow diagram of Fig. 9 is applicable to all displays wheelwork 70 that comprises more than three arms.
As shown in Figure 7, as first to the 3rd arm 72a, when 72b, 72c in one plane are connected in moving body 71, the motion of control moving body 71 on three-dimensional by the length of controlling first to the 3rd arm respectively.First to the 3rd arm 72a, 72b, 72c connection in one plane refer to, and at the some place away from the virtual line of the tie point that is used to link the first and second arm 72a, 72b, the 3rd arm 72c is connected to moving body 71.First to the 3rd arm 72a, 72b, 72c in one plane are connected in moving body 71 makes moving body 71 to rotate along variable direction.
The rotation of display rotating apparatus 70 is described below with reference to the process flow diagram of Fig. 9.Operation S91 is the instruction that input is rotated moving body 71.In original state, display rotating apparatus 70 is near fixed body 74.Under this state, the beholder who is positioned at display the place ahead can obtain suitable visual angle.But when the beholder changed its position, the visual angle of display diminished.Therefore, the beholder can make moving body 71 rotate the visual angle of controlling display by using a teleswitch etc.Can receive these input signals by the receiving trap that is connected in display rotating apparatus 70 from telepilot.
The operation S92 of Fig. 9 determines reference value and produces the control signal that is used for each drive division by the amount of spin of each drive division that calculates a plurality of arm 72a, 72b, 72c (corresponding to from the movable part 71 of input signal and distance and the angle between the fixed body 74).That is, will be calculated to be the amount of spin of drive division by control part from the input signal of telepilot.This calculated value compares as reference value and with the fiducial value that describes below.
The operation S93 of Fig. 9 rotates each drive division of a plurality of arms by receiving control signal.Make the motor of drive division turn over the amount of spin of determining by control part.The amount of spin of drive division by being connected in drive division sensor measurement and be transfused to value as a comparison.Can use Hall element and magnet in these sensors.
The operation S94 of Fig. 9 determines fiducial value by the amount of spin of measuring drive division.Hall element by being connected in drive division and magnet and the amount of spin of correct measurement drive division.
The operation S95 of Fig. 9 stops drive division if the difference between fiducial value and the reference value satisfies target offset, and if do not satisfy this deviation then by input control signal drive division is rotated.Carry out these operations S93, S94, till the difference between reference value and the fiducial value satisfies this deviation.Herein, deviation is the value that is input to control part in advance.
Simultaneously, during display rotating apparatus 70 rotated by this way, moving body 71 may collide wall for some reason.Therefore, distance detecting sensor 77 sends to control part in real time with the distance signal between moving body 71 and the fixed body 74.If this distance signal satisfies deviation, then control part can stop operating, and arm is extended along collision course, to avoid collision." deviation " is expressed as the collision of avoiding between moving body 71 and the fixed body 74 and the minor increment of importing in advance.
Control method is to use distance detecting sensor 77 to prevent collision between moving body 71 and the fixed body 74.In addition, prevent that collision from can followingly realize: the rotation of measuring the rotation axis of hinged component and arm by the stop part that is connected to hinged component, measured value is sent to control part, the amount of spin of the hinged component by each arm is determined the position of moving body 71, and the rotation of controlling arm by control part.
Because novel feature of the present invention has been pointed out in top being described in when being applied to each embodiment, those skilled in the art should understand that, in the case without departing from the scope of the present invention, can carry out various omissions, replacement aspect the form of device that illustrates or process and the details and change.Therefore, scope of the present invention is defined by the following claims, rather than is limited by the description of front.All contain within the scope of the claims in the implication of claim equivalent and all changes in the scope.
