- 2004 1 q8 DESCRIPTION OF THE PRIOR ART

Though conventional TV receivers are available in a variety of designs the viewer (user) cannot freely move the receiver back and forth, up and down or right and left as any desires using a remote control. Therefore, when the user wishes to change the viewing direction or movement of a traditional TV set, he/she has to move the TV set itself by him/herself or manually push or pull a wheeled support for the set. This results various inconveniences in using the receiver. Especially the stereotypical perception of a TV receiver, which means simply placing and viewing it in a single-fixed location couldn't be overcome.
Consequently manufacturing companies as well as general consumers have longed for an appearance of a hi-tech TV receiver that can bring different images and dimensions deportioned from the old perception of TV
set.

SUMMARY OF THE INVENTION

In a specific aspect of the invention there is provided an improved TV receiver comprising a head having a CRT tube and a body equipped with a position adjustment mechanism located in a space defined within the body.
Means is provided for enabling the head to rotate by operation of the D

~a~4 1 ~

position adjustment mechanism inside the space and linked to the head. A
freely-rotating caster and a pair of driving wheels which are coordinated with the position adjustment mechanism are actuable by remote control means enabling the head and the body to move together, forward and backward and side to side. The remote-controlled position adjustment mechanism is also operable to enable the head to selectively tip left and right to a predetermined angle and to pan left and right to a predetermined extent.
The invention is designed to minimize the inconvenience of using conventional TV sets and to offer a high technological TV set dividing TV as the head portion including CRT-tube and the body portion installed driving equipment which is supporting the head portion. The head portion is connected onto the upper portion of the supporting frame (body) so that only the head can pan over, tilt up and down, and move upward and downward by the driving equipment in a sequence.
Therefore, when a viewer steps out of vista (visual range), for instance, the viewer moves from living room to kitchen to have a meal while intending to keep on watching the TV screen simultaneously, the viewer can remote-control the head to pan left or right. Furthermore, when the TV set itself can't be seen from kitchen, the -2a-2~4~98 viewer can remote-control it back and forth and truck left and right to make the TV set visible. And even in a lying-or-leaning posi-tion, the viewer can remote-control the head for a dolly in and out or pan left and ri~ht to a certain an~le and have the best possible viewin~ condition for him/herself.
This hi-tech TV invention, deportioned from the conventional perception, makes possible to view the screen from any angle and any direction by remote-controlling the receiver itself.
The supportin~ frame (the body) of the moving TV receiver consists of a fi~ed frame and a fixing member which the motor, elec-tronic clutch, caster and driving wheel are built in with sprocket, chain, sector gear and screw shaft. These elements are combined with the driving ~ear on ~hich the transmission shaft and driving shaft are connected to the head portion above the body, and these are controlled to shift the moving TV set in ever~ desired direc-tion.
When it's necessary, a viewer can pan only the head left and right at a portionicular angle within 60 dearees, incline and dec~ine at a portionicular slope within ~0 degrees, tilt up and down at 15 degrees and 3 degrees, and move up and down within 200mm - heiaht, so that the viewer can have a total control over the TV set even when moving around and out of vista.

DESCRIPTION OF THE PREFERRED EMBODIMENT

In order to grasp the overall structure of the moving TV receiver 1, as shown in Fig. 1, the upper portion is the head portion 2 in global form similar to human head and the lower portion, the body 3 of which the internal space room is having a plurality of assembly is holding a driving gear in it. The back cover 6 with a ventilating opening 5 in it and the front cover 7 constitute the global head 2 and a circular speaker 8 is installed at each side. A supporting cover 37, designed to prevent the space when controlling to pan or tilt, is built between the head 2 and the body 3. Down the space room of the body, casters 11, 11' are installed perpendicular to the driving wheels 10 10' on the driving shafts 22, of the internal driving gear. On the out left of the body, AFT and A/V terminal plate 12 are installed to connect the antenna code and terminal of a video tape recorder. Along the power code 13 which is connected 200419~3 to the body 3, a winding device 15 is set in, allowing the TV set to move back and forth, right and left. The overall appearance is designed to make automatic winding possible. As shown in Fig. 2, 3 and 4, the space room 4 of the body sustaining thè upper head-set 2 of the moving TV receiver 1 consists of the fixed frame with a driving gear built in. Under it, transmission shaft fixed boss 17, 17', 17'', 17''' and the driving shaft fixed boss 18, 18', 18'', 18''' are integrally formed. In the driving shaft fixed boss, the wheel gets installed at eachside, and the driving shaft 22, in which the magnetic clutch 19 and the vertical gear 21 are built in, is installed on the same shaft to control driving force instan-taneouly.
This driving shaft 22, 22' is divided into two shafts 22, 22' centered on the magnetic clutch 19 on it. And under the fixed frame 16, the transmission shaft fixed boss 17, 17' contains the transmission shaft 23, 23' the magnetic clutch l9a is installed centered on the shaft, and around the center of the eletronic clutch l9a. The driving gear 24 is built clogged with the vertical gear 21 of the driving shafts 22, 22' on the one transmission shaft 23, 23'. The driving sprocket 20a is built for continuing movements of the vertical sprocket 20 and the chain 25. Beside this, another sprocket 20b is installed to cut the driving force on the shaft.
The transmission shaft 23' is also divided into two shafts by the magnetic clutch l9a. The driving shafts 22, 22' and the trans-mission shafts 23, 23' activating the eletronic clutches 19, l9a on the two shafts by the control of the printed circuit board in the space room of the body 3, help the shafts attach and detach to control and to deliver the driving force.

2()~4~9~3 Underneath the fixed frame 16, the casters 11, 11' established perpendicular to the driving wheels 10, 10' on each side of the dri-ving shafts 22, 22' are located lower than the lower portion of the body 3, so that only the driving wheels 10, 10' of the driving shafts 22, 22' and the caster 11, 11' contact each other in order to move the receiver (1) itself to back and forth, or left and right by the rotating movements of the casters 11, 11' that followed by the driving wheels 10, 10' rotating after the movements of the driving shafts 22, 2~' and the transmission shafts 23, 23' activated by the driving device installed in the space room of the body 3.
As shown in the Fig. 2, the upper portion of the fixed frame 16 in the space room ~ of the body is centered by thé perpendicular trans-mission shaft 26 connected to the lower side of the head 2 by the foot step oearind 27.
On each side of it, the motor M2 and M3 are put and the small sprockets 28, 28a are installed on each shaft, and the small sproc~et is connected to the sprocket 20b and the chain 25a put on the transmission shafts 23, 23' of the lower of the fixed frame 18 of the space room ~ of the body 3.
Another small sprocket 28 installed on the other motor M3 of the upper fixed frame 16 is connected to the lower portion of the head set 2 of the movin_ TV receiver 1 in order to connect itself to the sprocket 20c to the perpendicular transmission shaft 26, established perpendicular to the foot step bearing 27 at the center of the fixed frame 16, can pan only the head portion 2 of the moving TY receiver 1 at a portionicular angle to left and right.
On the upper portion of the transmission shaft 26 installed per-2~ 98 pendicular in order to rotate itself by the foot step bear,ing 27 atthe center of the fixed frame 16 of the body's internal space room 4, connected to the lower portion of the upper head 2 of the moving TV
receiver 1, constructs the revolving disc 29. On the upper side, a fixing member 30, 30' are formed at each ~ide, and the motor M1 is installed between the fixing member 30, 30' on the revolving disc 29 to put the small sprocket 28b on the shaft. At each shaft of the fixing member 30, 30' on the revolving disc, as shown in the Fig. 3, a rotating shaft 31 is built in and the sprocket 20d connected to the small sprocket 28b on the motor M1 shaft installed on the revol-ving disc ~9 on this shaft and the chain 25c.
Another sprocket 20e is built at the center of the rotating shaft 31, designed to clog the chain rack 32 fixed onto the lower portion of the head 2. At each end of the fixing member 30, 30' on the revolving disc 29, like the Fig 3. illustrates, the rotating rollers 33, 33', 33'', 33''' are installed to be hung on the upper and lower portion of the supporting member 36, 36' to work with the fixed disc 35 fixed on the fixed rib 34 of the lower head 2.
When the sprocket 20e at the center of the rotating shaft 31 clogs with the chain rack 32 fixed on the lower head 2, control of angle at a portionicular degree to decline left and right by the rota-ting movements of the Motor h~1 on the revolving disc 29 becomes evident.
Also, between the lower portion-of the fixed rib 34 on the lower side of the fixed disc 35 which supports the head portion 2 while fixed onto the fixed rib 34 inside the lower portion of the head 2 and the body (supporting frame), the supporting cover 37 is connected to the fixing member 30, 30' supporting the head by its lower side and 20~4~98 preventing the space 38 of the fixed disc 35 from being projected o~utward.
On each extreme inside the supporting cover 37 which is built in between the head portion 2 and the body 3 of the moving TV recei-ver, the limit switches ~L~1) (LM2) are installed in the way to con-trol the angle of the head portion 2 at a certain degree to decline left or right.
As explained by Fig. 3 and ~, Fig. 7 features the movin~ TV
receiver comprising the head and the body portion. On the lower face of the fi~ed frame 16 of the inner space room 4, there is the transmission fixed ~oss 17, 17', 17'', 17''' and the driving shaft fixed boss 18, 1~', 18'', 18''' are integrally formed with each other. The driving shaft fixed boss 18, 18', 18'', 18''' i5 proYided with the driving wheels 10, 10' on its both ends and also with an eletronic clutch 19, sprocket 20 and driving shafts 22, 22' which are equipped with a vertical gear 21. These driving shafts 22, 22' are seperated by the eletronic clutch 19. The transmis-sion fixed boss 17, 17', 17'', 17''' is provided with the transmis-sion shafts 23, 23' with the center thereof equipped with an eletronic clutch l9a. On one side of the transmission shafts 23, 23' the vertical gear 21 is mutually engaged to a driving gear 24. On the other side, a driving sprocket 20a which is connected to the vertical sprocket 20 on the driving shafts 22, 22' in chain.
Next to the device, a sprocket 20b which sends a movement to the shafts is installed. The transmission shafts 23, 23' are also seperated by the central eletronic clutch l9a for the driving shafts 22, 22' and the transmission shafts 23, 23' to activate the electro-200a.198 nic clutches 19, l9a on both shafts using the control from the printcircuit board in the space room 4. There are also installed the casters 11, 11' where they meet the driving wheels 10, 10'. In doing so, the body portion is placed below the bottom half so that only the driving wheels 10, 10' and the casters 11, 11' contact the floor when the TV receiver is stood up. Thus, as the driving wheels rotate according to the movement of the driving shaft 22' and the transmission shaft 23, the caster 11, 11' rotates enabling the moving T~7 Receiver 1 to move back and forth, left and right. Be-tween the head 2 and the body portion 3, the moving member 39 which provides up and down movement installed. The upper half thereof supports the lower side of the head 2 with its lower half is inser-ted into the space room 4 of the body portion 3.
Inside the moving member 39, a fixed member 40 is installed, forming sector arms 41, 41' on its both ends. At the inner side of these sector arms, a sector shaft which is integrally formed with a semi-circular sector gear 43 is provided for revolving movement.
A coupling frame 44 is also integrally formed with the upper side of the sector gear 43 and fixed to the fixed rib which is installed on the inner side of the head portion 2. Surrounding the frame ~, a semi-circular cover 45 is placed in order to prevent the gap be-tween the head 2 and the moving member 39 from protruding. And, the sector gear 43 installed on one side of the sector shaft 42 is mutually enga~ed to the spear gear ~6 which is provided on the motor shaft (M5). This device is designed to control the tilting move-ment of the head portion 2 as the sector gear 43 rotates according to the rotation of M5.
.~lso, on one side of the moving member 39 which is inserted be-- 20041sa tween the head and the body portion of the Moving TV Receiver, ano-ther motor (M6) is installed facing downward. A small sprocket 28c is fixed to the end of the motor shaft while it protrudes from the lower side of the fixed member 40. At the center of the lower side of the fixed member 40, a fixed shaft 47 is formed. A
sprocket 20f on one end of the shaft is linked to the small sprocket 28c in chain 25d. As shown in the Fig. 10, a double-row trust bearing 48 is installed on the lower half of the fixed shaft 47.
Below the device, a screw shaft 49 is suspended for free rotation work. And on the screw shaft 49 which can seperately operate with the help from the double-row trust bearing 48 along with the fixed shaft 47, a key home 50 as illustrated by the-Fig. 11 and 12 is formed on the lower portion of the space room 4 and inserted in the fixed bushing 52 which is installed at the center of the supporting member 51. Between the screw shaft 49 and the fixed bushing 52, the key home 50 is provided with a key which will guide the up and down movement of the screw shaft 49.
The fixed bushing 52 is integrally formed with the screw shaft 49 at the center of the fixed member 40 in the moving member 39.
On the upper half thereof,a single row trust bearing 54 is installed with its upper side provided with the sprocket which forms a screw thread 55 that is connected to the screw shaft 49 as shown by the Fig. 12. This sprocket 20g is linked in chain to the small spro-cket 28d which is installed on the motor M4. Here, M4 is facing upward while installed on one side of the supporting member 51.
Thus, as the motor M4 revolves, the sprocket 20$ on the screw shaft 49 rotates, enabling the screw shaft 49 to move up and down.

2004.~98 Accordingly, the head portion 2 which is connected to the moving member 39 moves up and down.
On both sides of the upper half of the moving member 39 and of the supporting member of the space room 4 which contains the moving member inside it,the limit switches LM5, LM6, LM7, LM8 are installed to control the range of tilting angle and height of up and down movement of the head portion 2.

Following is how to operate the present invention.

(First embodiment ) When the viewer intends to move the Moving TV Receiver while watching the TV, the viewer can turn on the powér key of the TV
receiver. Then, the start signal " H " sent by the motor interrupt port interrupts the electric power that is supposed to go to the motor Ml, M2 and M3 respectively. As the next step, the relay (Ryl) coil of the motor Interrupt driven portion A10 is excited, closing the related contact al and a2. Here, the electric power stays on the contact a which is commonly shared by All, A12, A13.
The same power also stays on the No.l pin commonly shared by the speed controller SCl, SC2 and SC3.
As it is, when the viewer ~user) pushes the mode selection button 57' which directs back and forth movement, the signal as shown by the Fig. 19 is sent to the transistor Q4 via diode D5, re-sistance R5 and condenser C4 from micom output port C. Simulta-neously, a seperate power Vcc is sent to Q4 and Q5 via R6 and R7, becoming equipotential to the previously mentioned power. Then, the signal excites the Ry3 coil at the motor driven portion A12. At the `, , 2~41g8 same time, the contact a at Ry3 is closed, sending the alternating current (AC hereinafter) to the contact a of battery driven relay (Ry7) ~Ry8~.
If the vewer pushes the botton (v) among the movement selection bottons : (>) (<) (v) (^), the signal decided by the output port G
excites the Ry7 coil, closing the contacts al, a2 and a3. The same power throuoh al is sent to the board 2 of the speed controller Sc2 and the eletronic clutch l9a. The power adjusted by the variable resistance inside the Sc2 is sent to the terminal 01 at the motor switching circuit B11 by way of the contact a2, making the motor ~2 to rotate (turn). This M2 is linked to the sprocket 20b on the transmission shaft 23 and is fixed to the lower side of the fixed frame 16 of the space room l~). At the same time, the magnetic clutch on the driving shaft 22 22' is provided with power while the manetic clutch l9a on the transmission shaft 23, 23' is set off bv the repulsion eletronic power from the power provided by the contact of Ry7. This way, the turning of the motor M2 is sent to the sprocket on the transmission shaft of the fixed frame 16 through chain 25a, allowing the transmission shaft 23 and the driving sprocket 20a to turn accordingly. Then, the driving shaft 22 which is divided to two shafts revolves as the driven sprocket 20 which is connected to the sprocket 20a in chain revolves. The other driving shaft 22 turns in the same direction, with the driving wheels 10 10' which are installed on both ends of the driving shafts 22 22', allowing the entire Receiver to move forward as illustrated bv Fig. 17.
The viewer can release the movement selection button (v) when the Receiver has moved as he/she desired. Then, the si~nal from `- Z004198 the micom output port G is inverted, disconnecting the AC .power which is being sent to the motor M2. When the motor M2 on the fixed frame 16 stops operating, the Receiver also stops moving, with the eletronic clutch 19a bein~ able to connect the seperated transmission shafts 23 23'. Conversely, when the viewer intends to move the Receiver backward while the multiplexer MP2 and the motor driving portion A12 are operated by the control si~na`l from the micom output port C, he/she can push the botton (^), which will be sent to the transister in the relay driving portion A1~ for direction switching mode b~ way of D15, R1~ and C11. In the mean while, the relay Ry8 is e~cited by the independent po~er Vcc and the contancts al, a2 and a3 are closed. And, the AC power through al is sent-to the pin No.2 of Sc2 and the magnetic clutch l9a. The power readjusted by the variable resistance within the speed controller is again transmitted to the reverse terminal 02 and then to the motor ~2.
Contrary to the movement mentione~ above, the motor M2 installed on the upper side of the fixed frame 16 counter-revolves while the eletronic clutch on the driving shafts 22,22'become united as one shaft so that power transmission is made possible. The eletronic clutch 19a on one side of transmission shafts 23,~3' make the shafts seperated with repulsion magnetism, sending the counter revolving motion of the motor M2 to the sprocket 20b installed on one end of the transmission shaft 23 through the chain 25a. As the transmission shaft 23 rotates, the other sprocket 20a on the same transmission shaft 23 counter-revolves. Then the driving sprocket 20 on the driven shaft 22 which is linked to the above-mentioned sprocket by the chain 25 rotates, making the driving Z00419~ , shafts 22 22' to rotate in the opposite direction.
For the driving shafts 22,22' are united as one by the eletronic clutch 19, they turn in the same direction as the transmission shaft 23, which in turn operates the drivin~ wheels on each end 10, 10', allowing the Receiver to move backward as shown by Diagram 17.
When the viewer releases the direction selection mode button (^) , the signal from the micom output port H is inverted, disconnecting the AC power which is being provided to the motor M2 while the contacts al, a2 and a3 of the relay driving portion A17 and relay Ry8 open.
Likewise, the Receiver stops moving backward while at the same time the other transmission shaft 23' which was seperated from the shaft 23 become united as they were.
When the user intends to move the Receiver to the right while the motor interrupt driving portion A10 together with the multiplexer Mp2 and the motor driving portion A12 are normally operating by the control signal from the micom output port C, he/she can push the selection button 57' for right and left movement. The signal is sent to the transistor base [2] at the multiple~er through the diode 3, [3],resistance [2] and condenser [2] starting from the micom output port B. ([ ] lS not shown).
~ imultaneously, an independent power (Vcc~ is sent to the transister [2] and [3] via the resistance [3~ [~], keeping equipotential to each other. Then the inverted signal e~cites the relay Ry2 coil of the motor driving portion 11.
Here, the contacts al and a3 which are for direction selection mode is provided with the signal as the contact a at the relay Ry2 is closed.

2~ti~8 In order to move the Receiver to the right, the viewer can push the selection mode button (>) out of the four selection modes (v) (<) (^) (>). Then, the signal from the micom output port G is sent to the driving portion (A16) throu~h Dl3, R13 and C10.
At the same time, the relay Ry7 is activated, closing the con-tacts al, a2 and a3.
When the contact a at the relay Ry2 is closed, the AC power from the contact a at the Ry7 is transmitted to the magnetic clutch l9, producing repulsion magnetism, which in turn opens the eletronic However, since the relay driving portion Al~ is in a passive state, the contact a3 at the Ry8 remains off, while the eletronic clutch is -united by the magnetism, connecting the transmission shafts 23 and As the contact al at Ry7 is closed, the AC power from the same contact is sent to the pin No.2 of the speed controller SC2.
At the same time, the power which was varied by the variable resistance inside SC2 is transmitted to the terminal 01 and finally to the motor M2.
Then, the motor M2 which was installed on the upper portion of the fixed frame of the space room ~ seperates the driving shafts 22 , 22' by the inside circuit control. Union of the magnetic clutch 19a on the transmission shaft 23,23'sends the rotating motion of the motor M2 to the transmission shaft 23, 23' throught the chain 25a.
As the shafts 23, 23' turn, the driving sprocket (20a) on the same shafts also turn, driving the vertical sprocket 20 which is linked in chain. Finally, the rotation of the driving shaft 22 allows the driving wheel 10 turns clockwise.
Here, the rotation of the transmission shaft 23 is sent to the 20~ 9~
driving gear 24 by way of the eletronic clutch 19a, counter-rotating (counter clockwise) the driven gear on the driving sha~t 22' which is mutually engaged to the driving gear. As the driving shaft 22' and driving shafts 23, 23' turn in the same direction while the driving wheel on other end rotates counter clock wise. The driving wheel on each extreme of the driving shaft 22, 22' which are divided by the eletronic clutch 19 rotate in the opposite direction to each other, beina able to turn 360 degrees to the right.
Then, the head portion of the Moving TV Receiver turns to the right, and the viewer can release the selection button (<) when he/she gets the very angle he/she desired.
Accordingly, the signal to the micom output port G interrupts the movement of the relay driving portion A16 for selection mode.
When the viewer pushes the button (V) again, the signal from the micom output port ~ orders the motor driving portion A11 to stay in a passive state, turning off the power which was provided to the contact a3 at the Ry7, Ry8.
When the viewer pushes the selection button (V) again, repeated movement of the Ry7 of the relaty driven portion (A16) for selection mode allows the Receiver to move forward simultaneously as it turst to the right, resulting in movement to the right as shown by Fig.18.
When the viewer releases the selection button (v) after the TV
Receiver has moved as he/she desired, the signal from the micom output port G is inverted as mentioned earlier, disconnecting the AC power which is being sent to the motor M2 with the contacts a, a' at Ry7 remain open. This is followed by the interrupted movement to the right of the Receiver and by the eletronic clutch 19 on the shafts 22, 22' return to its previous state.

Z0~4 ~8 Also, contrary to what is mentioned above, when the viewer intends to move the Receiver to the left, he can select the panning selection mode 57' and the power is provided to the contacts a3 at Ry7, Ry8 by the operation of the motor drivin~ portion A11 and the relay Ry2. Afterward, when he/she pushes the button (<~, the signal from the micom output port H is sent to the relay driven portion for selection mode through D1~, R1~ and C11, closing the contacts al, a2 and a3 with the relay (Ry8) coil being excited by the independent power Vcc.
The AC power from the contact al is sent to the pin No.2 of the speed controller SC2 while the power adjusted by the variable resistance inside the speed controller SC2 is trans~ered to the reverse terminal 02 and then to the above mentioned motor ~2 throu~h the contact a 2 at Ry8.
Then the motor starts turning reversely. Thus, the motor M2 provided with the transmission shafts 22, 23' which are installed in the upper side of the fixed frame 16 of space room (~) also counter-rotates with the driving wheel 10 on the driving shaft 22 turning counter clockwise. In the meantime, the other driving shaft 22' and wheel 10' turn clockwise so that the Receiver itself turns 360 degrees to the left. ~hen the viewer releases the selection button (<) after the Receiver reaches the right angle he~she desires, the signal from the micom output B makes the motor driving portion A11 to stop all its movement.
This way, the power sent to the contact a3 at Ry8 of the relay driving portion A17 for selection mode is turned off. At the same time, the inverted signal from the micom output port H keeps the ` Z004198 relay Ry8 at the relay driving portion for selection mode also remains in a passive state.
As it is,when the viewer pushes the button for upward movement, the signal fro~ the micom output port H activates the relay Ry8 of the relay driving portion A17 for backward movement, enabling the head portion 2 which is turned to the left starts moving back, finally allowing the receiver itself to move to the left as shown by Fig.18.
When the viewer releases the selection button (<) as the Receiver moves in the direction (to the left) as he/she desires, the inverted signal from the micom output port opens up the contacts a, a' at Ry8, interrupting the AC power being provided to the motor M2.
In order to turn the Receiver to face forward, the viewer can push the button ~<) (>) for selection mode on the remote control (~6) , the Moving TV Receiver starts turning left and right.
~ ith the 90 turned receiver facing the front side, releasing the direction button (<) (>) fixes the receiver to the front side.
As described above, at the time of the receiver's moving, the power code cable connected to the receiver is automatically wounded or unwounded in proportion to the receiver's movement,by the winding machine stucked on the floor and the power code cable is simultane-ously and automatically positioned.
The length of the power code is optionally set in accordance with the maximum moving range of the receiver and wounded with the winding machine for use.

(Second enbodiment) In order to move the receiver's upper head portion to the left or 200~198 the right for the viewer's visibility,he should press the visibility control motor selection button 57" as shown in the illustration Fig.
13 among those mode selection buttons 57, 57', 57'' of the remote control 56. And the signal is transmitted to the multiplex PM3 through the diode D7, resistance R8 and the condenser C2 at the un-illustrated output port of the micom.
At the same time, a separate electricity power (Vcc~ is transmitted to the transistor Q7 of the motor driving portion A13 through resistance R9, R10 , to secure the same-level electricity potential and to reverse the signal and to excite the relay Ry4 coil of the motor driving portion A1~.
Then the contact point a of this relay Ry~ is closed and the A.C. power is induced to the relay Ry5 contact point a2 of the driving portion A14 for selection of direction and to the relay Ry6 contact point al of the driving portion A18,A19 for selection mode.
Thereafter, pressing the direction button for the right (>) among the direction buttons (<) (>) (^) (v) of the remote control 56 transmits the power to the transistor Q13 of the relay driving portion for selection of direction A15 from the unillustrated output port F of the micom through the diode D19 , resistance R16 and the condenser C13 . So, a separate electricity power (Vcc) is transmitted to the relay RylO coil through the limit s~itch LM2 and the coil is exceited.
At the same time, the contact points al, a2 are closed and the A.C. power is transmitted through the contact point al to the No. 2 pin of the speed controller SC3. The power adjusted by the variable resistor (unillustrated) in the speed controller SC3 flows to the direction-reversing terminal 02 of the motor ZO~:~198 conversion circuit B12 throu~h the contact point a2 of the above relay RylO.
Here, the motor (1~3J fixed at the fi~ing frame 16 of the upper portion of the vertical transmission shaft 23, 23' in the inner space room ~ of the receiver's lower body portion(3) rotates clockwise, turning the small sprocket (28) stuck on the motor.
Then, the movable sprocket (20C) of the vertical transmission shaft ( 26) installed on the footstep bearing (27) of the fixing frame ~16)'s-center-upper portion linked with the small sprocket rotates clockwise and the vertical transmission shaft (26) also rotates.

Then, the revolving disk (29) of the vertical transmission shaft (~9) rotates and both of the fi~ing member (30) (30'~ set up on the disk also rotate, to turn the fi~ed disk (3~) integrated in a sin~le body on the both fi~ing member(30) (30') and st~ckto the receiver(1)'s head portion (~) in the direction of the vertical transmission shaft (26 )'s movement.

According to the movement of the head fi~ed disk (31), only the head portion (2) of the receiver (1) stuck there on rotates in the same direction, say, to the right.

When the receiver(1)'s head portion(2) moves as much as the viewer wants, he should release the direction button for the right (>) of the remote control (56). Then, the motor(13) stops and the receiver(1)'s head portion (2) is positioned as wanted.

2(~(~4138 Even though the viewer continues to press the direction button for the right by mistake, the head portion(2) rotates no more than30 degrees.
That is, in case the head portion (2) reaches the ma~imum turning point and the lower portion of the head portion(2) turns to the maximum, the limit switches (LM3) (LM4) installed at both sides with a certain distance in the lower portion of the head portion (2) turn off, to finish movementss of the relay (Ry9) (RylO) and to bring the motor (M3) to a standstill.

Therefore, in spite of the viewer's keepina pressin~ the direction button for the right (37') of the remote control (~6) by mista~e, the motor (~f3) stops by the limit switches (LM3) (LM4) installed in the lower portion of the head portion ~2) and the head portion (2) is controlled not to move beyond the maximum movina angle 30 degrees.

The a~ove-described mechanism enables the head portion(2) of the receiver(1) to be remote-controlled and to move to the right as far as the viewer wants with the range of 30 degrees.

Likewise, when the view wants to move the head portion (2) of the receiver(1) to the left, he should press the direction button (~) among the direction buttons (v) (^) (<) (>).

Then the si~nal from the output port(E) often micom activates the direction-selecting relay transmission portion (A18) in the opposite way OI the previous case and the power through the contact Z004~98 points al, a2 turns the motor (M3) anti-clockwise through the speed -controller (SC3) and the conversion circuit (B12), which rotates the motor (M3) above the fixing frame (16) in the inner space room(4) of the receiver(1)'s body portion(3) clockwise. It also rotates the fixing member (30)(30') and the fixed disk (35) integrated in a single body on the fixing member and fixed to the bottom of the head portion (2) anti-clockwise, which, in turn, turns the head portion(2) to the left.

When the head portion(2) of the receiver(l) has moved to the left properly for visibility, he should release the direction button (<) of the remote control (56), which stops the motor (M3) and the movement of the head portion (2). In that way, the head portion(2) moves to the left for the viewer's visibility within the range of 30O degrees.

Accordingly, the head portion(2) of the receiver(1) moves freely to the right or left within the maximum range of 60 by the remote control, to secure the viewer's visibility.

(Third embodiment) When the viewer wants the head portion(2) of the receiver(1) to lean toward the right or left during watching the television, he should press the inclination button (57"), the lowest of the mode selection buttons (57) (57') (57'') as shown in the illustration Fig.
8. With that action, the mode selection is transmitted to the 200~138 multiplex (~P1) at the unillustrated output port (B) of the micom through the diode (D3), resistance (R3), (R2) and the condenser(2) At the same time, a separate electricity power (Vcc) is transmitted to the transistor (Q2) through resistance (R3) (R~ and the transistor (Q3) of the motor transmission portion (A11), to make the same-level power potential and to reverse the signal, which excite the relay (Ry2) coil of the motor driving portion (A11).

Then, the contact point a2 of the relay (Ry2) is closed and the waiting .~.C. po~er is induced to the relay (RyS) contact point a of the direction-selecting relay drivin~ portion (A1~) and to the relay (Ry6) contact point a of the direction selecting relay driving portion(.~15).

At this moment, if the viewer press the direction button to the right ~>) among the direction buttons (<) (>) (^) (v), it is transmitted to the transistor (Q9) of the direction-selecting relay driving portion (A15) from the unillustrated output port (F) of the micom through the diode (dll) resistance (R12) and the condenser (C9), while a separate electricity power (Ycc) is transmitted to the relay coil (Ryl6) through the limit switch (LM2).

Then, the coil is excited and simultaneously the contact points al, a2 are closed. The A.C. power through the contact points al is transmitted to the pin No. 2 of the speed controller (SC1) and the power adjusted by the unillustrated variable resistance in the speed controller (SC1) flows to the ~'''~"'" 2~a~lq~
direction-reversing terminal (0~) of the motor conversion circuit (B1 O) through the relay (Ry6) contact point a2 and is transmitted to the motor M1.

Here, the motor tM3) fixed at the revolving disk (29) of the upper portion of the transmission shaft ~26) in the inner chamber of the receiver(l)'s lower body portion (3) rotates anti-clockwise and the sprocket (20d) installed on the revolving shaft (31) and chain-connected with the sprocket turns, which rotates the sprocket 20e~ on the shaft anti-clockwise.

~ hen, en~agin~ with the sprocket (20e) turnino anti-clockwise, the chainrac~ (32~ integrated in a single body at the bottom side of the fi~ed dis~ (3~) of the lower portion of the head portion(2) moves in gear with the sprocket (~Oe) and rotates to the left, ~hich makes the head portion (2) of the recei er (1) lean toward the right side and rotate.

As this juncture, the round-type supporting member(36,36') of the fixed disk(3~) adjoins and moves among the revolving rollers (33,33', 33'',33''') on the lower fi~ing member(30,30') as shown in the illustration Fig. ~, which prevents the fixed disk from rattling during the leaning head portion(2)'s turning for a smooth movement and acts as a sliding guide for the fi~ed disk (3~).

As the head portion(~) has leaned toward the right side as much as the viewer wants~ releasing the direction button (>l of the remote control (36) reverses the signal from the output port of the micom, to open the contact points al, a2 of the direction-selecting relay 200~ 8 driving portion (al5) and the relay (Ry6) and to cut the A.~. power to the motor (~1).

With the stoppage of the motor driving, the lelaning of the head portion (2) is brought to a standstill to ensure an appropriate leaning of the head portion (2) of the receiver(1) at an angle the viewer needs.

However, even if the viewer happens to press continuously the direction button (>) of the remote control by mistake, the head portion( 2)'s leaning cannot e~ceed 20 (the range of this maximum angle can be modified by the position of the limit switc~es.)., for there is installed the limit switches (LM1) (LM2) at a distance from each other inside the supporting cover(37).

In case the head portion(2) has leaned as far as to the designated angle (20), the head fixed disk (35) touches the limit switch (LM2) and cut the power to the relay (Ry6) coil by the limit switch (LM2) movement, regardless of pressing the direction button (>) of the remote control (56).

Consequently, the motor stops owing to the lac~ of the need power and the head portion (2) of the receiver (1) is controlled not to lean in excess of 20 to the right.

However, repositioning the limit switches (L1~1) (L~2) installed on the supporting cover (3~) allows the leaning rane of 20 - 60 to the right and the viewer may watch the television leaning within that range.

Likewise, when the viewer wants to have the head portion(2) of the receiver (1) lean toward the left side at a certain angle, he should press the inclination button (57'') and the direction button to the left (<) together. Then, the signal is transmitted to the transistor (Q8) of the direction-selecting relay dirving portion (A1~) from the unillustrated output port (E) of the micom through the diode (D9), resistance (R11) and the condenser (C8), while a separate electricity power (Vcc) is transmitted to the relay (Ry5) coil through the limit switch (LM1) and the coil is excited.

At the same time, the contact points al, a2 are closed and the A.C. power through the contact point al is transmitted to the Fig. 2 pin of the speed controller (SC1). The power is adjusted by the variable resistor (unillustrated) in the speed controller (SC1) and flows to the same-direction terminal (01) of the conversion circuit ( B10) and lS transmitted to the motor (M1).

Concurrently, the motor (M1) fixed on the revolving disk (29) of the upper portion of the vertical transmission shaft(26) in the inner space room (~) of the receiver(l)'s lower body portion rotates clockwise unlike the previous case and the turning of the motor (M1) is delivered to the chainrack (32) at the bottom of the head fixed disk (35) set up at the bottom of the head portion(2) of the receiver(1 through the small sprocket (28b), chain (25C) and the sprocket (20d) installed on the revolving shaft(31) between two fixing member(30,30' 20~198 ) integrated in a single body with the revolving disk (29) of the transmission shaft (26). The chainrack (32) turns and moves to the right following the sprocket (20)'s turning, which results in the head portion(2) of the receiver(l)'s leaning to the left and rotating.

When the head portion(2) has leaned as much as the viewer wants, he releases the direction button (<) of the remote control (56).
Then, the signal from the unillustrated output port (E) of themicom is reversed, which opens the relay (Ry5) contact points al, a2 of the left driving portion (14) and cuts the A.C. power to the motor (M1).

Consequently, it stops the moter (Ml)'s driving and the head portion(2)'s leaning. So, the viewer may watch thetelevision with the receiver (l)'s head portion(2) leaned to the left at a certain angle wanted by the viewer.

In this case, the maximum range of the head portion(2)'s leaning does not exceed the optionally designated angle controllec by the limit switch (LM1) fixed on the supporting cover.

Meanwhile, the movement of the motor on-off driving portion (A10) is made by pressing the motor on-off button (57'') of the remote control (56). It excites the relay (Ryl) coil of the motor on-off driving portion (A10) by the signal from the output port (A) of the micom and the A.C. power is supplied to each motor dirving portion (A11) (A12) (A13).

Under these conditions, the motor mode selecting buttons (57) (5 Z0~4198 7') (57'') and the direction buttons (<) (^) (v) (>) of the remote control are used to control each motor driving system of the receiver(1).

But, releasing the motor on-off button (57) of the remote control (56) stops the function of the relay (Ryl) coil of the motor on-off driving portion (A10), which cuts the A.C. power being supplied to each motor driving portion (A11) (A12) (A13).

The other functions of this invention are as follows.

(First embodiment) When the viewer wants to watch the television from above the screen-level or from under the screen-level and so the head portion (2) of the receiver(1) with the CRT tube (C) should be lowered down, he should press the height-adjustment mode selecting button (57) among the mode-selecting buttons (57) (57') (57'') of the remote control (56) for a mode selection and press the up-direction button ( ^) among the direction buttons (<) (>) (^) (v) of the remote control (56) for lifting the head portion(2) of the receiver(1).

Then, the revolvable motor (M4) on the support member (51) integrated in a single body on the fixing frame (16) in the lower portion of the inner space room(4) of the receiver (l)'s body portion(3) turns to the left and the small sprocket (28d) on the shaft turns in the same direction. But, the screw shaft (49) connected therewith by chain (25f) and put in gear with the screw thread (55) inside of the large sprocket (20g) on the sliding screw shaft(49) installed on the fixing bushing (52) at the center of the support 2~4198 member (51) does not turn, while only the sprocket (20g) turns to the left together with the single-row bearing (5~).

In this way, the screw shaft(49) is lifted in gear with the screw thread (55), without turning, just like a nut being screwed into a fixed bolt.

At this time, the keyhome(50) of the screw shaft (~9) is guided, slided and lifted at the key (53) inside the fixing bushing (52).

As the upper end of the screw shaft is fixed at the fixing member (40) in the drum-type moving member (39~ together with the double-row trust bearing (48) and the sprocket (20f), the screw shaft (49) is lifted with the whole drum-type moving member (39) and is fixed in the upper portion by the sector arms (41) (41') on the drum-type many member (39).

Thereafter, it is lifted with the connecting frame (44) on the sector gear (43) fixed at the bottom of the fixed rib (34) under the head portion(2) and with the semi-circular cover (45).

As a result, the head portion (2) of the receiver (1) is moving upward.

Nhen the head portion (2) of the receiver (1) has moved upward as much as the view wants, releasing the direction button (^) of the remote control (56) stops the motor (M4) on the support member(51) ~ 30 -20()~1198 at the bottoms of the inner chamber(4) of the body portion (3) under built-in circuit control and the upward-moving of the screw shaft (49 ) stops, which, in turn, stops that of the head portion (2) of the receiver(1).

Likewise, when the head portion (2) of the receiver 91) should be lowered down, the viewer should press the down-direction button (v) among the direction buttons (^) (v) (<) (>) of the remote control (56 )-Unlike the previous case, the motor (m4) on the support member ( 51) fixed at the upper side of the lower fixing frame of the inner chamber inside the body portion (3) is turned to the right, which rotates to the right the sprocket (20g) on the sliding shaft (49), connected thereto by chain (25f) and installed at the fixing bushing (52) at the center of the support.

Here, the screw shaft (49) goes in gear with the screw thread (5 5) inside the sprocket (20g) and remains unturned. Only the sprocket (20g) rotates to the right with the single-row trust bearing (~4).

Consequently, just like a nut being unscrewed out of a fixed bolt, the screw shaft (49) remains unturned by the turning movement of the screw thread (55) in gear inside the sprocket (20g) and is lowered down by the turning movement of the sprocket t20g).

The screw shaft (49) slides down along the key (53) in the fixing bushing (52) and is fixed at the top of the screw shaft (49), Z0~198 while the fixing member (~0) fixed in the drum-type moving member (39 ) moves down. As the connecting frame (4~) on the sector gear (43 ) connected at the fixed rib (34) under the head portion (2) is fixed in as a single body by the sector arm (41) (41') on the fixing member (40) linked with the screw shaft (24), the screw shaft (49) moves down together with the drum-type moving member (39) and the head portion (2) is lowered down. As a result, the head portion (2) of the receiver (1) moves down.

At the time the head portion (2) of the receiver (10) has moved down as low as the viewer wants, he releases the direction button (v) of the remote control. It stops the motor (M4) on the support member (51~ at the bottom of the inner chamber (4) of the body portion ( 3) which, in turn, stops the turning of the sprocket (20g) on the screw shaft (49), linked to the small sprocket (28d) on the motor (m4 ) by chain (25f). Then, the moving-down of the screw shaft is completed and the head portion (2) of the receiver (1) moves no more.

As above, the head portion(2) of the receiver (1) moves up and sown by remote controlling within the maximum range heigh-adjustment range of 200mm. Even if the viewer keep the direction buttons (^) (v) pressed beyond a proper adjustment by mistake, the drum-type movin~ member (39) touches the limit switches (LM5) (LM6) installed top and bottom inside the body portion (3), between the support member ( 51) in the body portion (3) and the drum-type moving member (39), at the time of the head portion (2) moving upward or downward to the maximum range of 200mm.

200~198 _ Then, the motor (M~) on the support member (51) in the inner space room (4) of the body portion (3) stops under the built-in circuit control and through the movement of the limit switches, to keep the head portion (2) of the receiver (1) from moving upward or downward in excess of 200mm.

As described above, the viewer may optionally adjust the height of the head portion (2) of the receiver (1) within the maximum range of 200mm through remote-controlling for a better convenience.

(Second embodiment) hhen the viewer wants the head portion ~2~ of the receiver (1) to lean forward or backward, he should press the leaning-control button (57''), the lowest of the mode selecting buttons (57) (57') (57'') for the mode selection, as shown in the illustration Fig. 16.

Thereafter, in order forthe head portion (2) of the receiver (1) to lean forward at a certain degree, he should press the direction button (v), the direction button (v) of the remote- control, which finishes the movement of the motor (M~) installed at the fixino member (~0) in the inner space of the drum-type moving member (39) under the head portion 92) and stops the turning of the sector gear (43) going in gear with the spurgear (46).

Then the head portion (2) leans forward no more and the view may watch the television with the head portion (2) of the receiver(1) ZC~)4 ~98 - leaning forward properly.

Even if the viewer keeps pressing the direction button (v) of the remote control (56) by mistake, the head portion(2) leans forward no more than 5.

.

As there is the limit switch (LM) installed at the point of the maximum allowable forwardleaning range 5, in the upper end of the drum-type moving member (39) under the semi-circular cover (45) and the connecting frame (44) fixed on the fixed rib (34) under the head portion (2), the head portion (2)'s leaning forward by the motor (M5)'s turning reaches the maximum range of 5 and then the turning semi-circular cover (45) presses and activates the limit switch in the drum-type moving member (39). So, regardless of keeping pressing the direction button (v) of the remote control (56), the limit switch stops the motor (M5) on the connecting frame and controls the head portion (2) of the receiver (1) not ot lean forward more than 5 :

In such a way, the viewer may optionally have the head portion (2) of the receiver (1) lean forward within the range of 5 , the lowest of the four direction buttons (^) (>) (v) (<), which turns clockwise the motor (M5) on the fixing member (40) in space of the drum-type moving member (39) under the head portion (2) of the receiver (1), through the built-in circuit control.

Then, the spurgear 46 on the motor M5 rotates in the same direction and the sector gear 43 engaging in gear therewith installed in a single body with the sector shaft 42 on the upper ZO~4198 end of the sector shaft 42 on the upper end of the sector arms 41, 41' of the fixing member 40 slowly start to rot6ate anti-clockwise in gear.

At this moment, the connecting frame (44) formed in a single body on the sector gear (43), surrounded by the fixed semi-circular cover (45) and fixed in a single body with the fixed rib (34) of the head portion (2) of the receiver (1) turns in the same direction by the sector gear (43)'s turning in gear.

As the head portion (2) of the receiver (1) fixed at the top of the connecting frame (44) rotates with the connecting frame (44).
Accordingly, the head portion (2) slowly leans forward.

Here, the semi-circular cover (4~) fixed around the connecting frame linked to the fixed rib (34) at the bottom of the head portion (2) covers up the backside space caused by the head portion (2)'s lean-ing forward ar,d ke,eps a fine appearance.

At the time the head portion (2) of the receiver (1) has leaned forward as the viewer wants through such a mechanical procedure, he should release.

Likewise, when the viewer wnats the head portion (2) to lean back-ward for a certain degree, he should press the direction button (^) among the direction buttons (^) ~>) (v) (<) of the remote control (56). It turns anti-clockwise the motor intalled on the fixing member (40) in space of the drum-type moving member (39) under the head portion (2) of the receiver (1) through the built-in circuit control, in the oppsite way of the previous case.

Then, the spurgear on the motor (M5) turns in the same direc-tion (anti-clockwise) and the sector gear (43) positioned at the top of the sector arms (41) (41') of the fixing member (40) and operated by the sector shaft (42) starts to turn clockwise in gear with the spurgear (46) on the shaft of the motor (M5).

At this moment, the connecting frame installed on the sector gear (43), surrounded by the fixed semi-ciralar cover (45) and fixed on top with the fixed rib (34) under the head portion (2~ of the receiver (1) turns in the same direction (clockwise) in gear with the sector gear (43).

So, the head portion (2) of the receiver (1) fixed on the connec-ting frame goes into driving with the connecting frame (44), which results in the head portion (2)'s leaning backward.

At this time, the semi-circular cover (45) surrounding the connecting frame (44) linked at the fixed rib (34) under the head portion (2) leans backward with the head portion (2) and covers up the space formed between the head portion (2) and the drum-type moving member (39).

~ hen the head portion (2) of the receiver (1) has leaned backward as the viewer wants, he should release the direction button (^) of the remote control (56). Then, the motor (M5) installed on the . - 36 -Z0~198 connecting frame (44) inside the drum-type moving member (39) under the head portion (2) stops and the movement of all the portions linked thereto stop, wh.ich finishes the leaning of the head portion (2).
So, the head portion (2) of the receiver (1) leans backward and is positioned as the viewer wants.

At this time, though the viewer keeps pressing the direction button (~) of the remote control (56) by mistake, the head portion (2) of the receiver (1) leans backward no more than 15 owing to the limit switch (LM6).

As there is the limit switch installed at the point of the maximum allowable backward-leaning range 15, and in the upper end of the drumtype moving member (39) under the semi-circalar cover (45) and the connecting frame (44) fixed on the fixed rib (34) under the head portion (2), the head portion (2) leaning backward by the motor (M5)'s turning reaches the maximum range of 15and then puts the limit switch (LM6) in motion. The motor (M5) on the fixing support (40) stops by the limit switch (LM6)'s movement and the head portion (2) of the receiver (1) is controlled not to lean back-ward more than 15.

As above, the viewer may optionally have the head portion (2) of the receiver (1) lean backeard within the range of 15.

As explained so far, this moving television receiver moves back and forth, left and right through remote controlling at the viewer's disposal and the upper head portion of the receiver itself Z0~4198 rotates left-or right within the range of 30 as the viewe~ wants.

Also, the upper head portion may leans toward left or right with the range of 20 by the remote control, if necessay, and the height of the upper head portion may be adjusted upward or downward within the range of 200mm. Further, the head portion leans forward or backward within the range of 5 and 15 respectively.

Accordingly, in case you want to watch the moving television recevier in the kitchen over the meal after watching in bedroom, you can move the whole television receiver to the position seen from the kitchen by the remote control. In addtion, you can remote-control the head portion on the body portion to be slanted at a certain degree and to rotate left or right at a certain angle.
Further, the head portion itself is adjusted to lean forward or back-ward and moves up or down in height.

Beyond the general concept of~ the television receiver, this invention creates an exceptionally new image of the television receiver moving in all directions with multi-functions and high-technology.
