Remote control operated moving television receiver

A mobile TV receiver is provided in which the viewing screen can move left and right or up and down and be tipped or tilted by remote control as the viewer chooses. The TV receiver is divided into a head portion including a CRT-tube and a lower body portion accommodating driving elements and supporting the head portion. The head portion is adjustably connected to the upper part of the supporting body portion so that only the head can lean over, tilt up and down, and move upward and downward by operation of the driving elements under the viewer's control. The viewer can thus remote-control the TV set back and forth, and adjust it exactly as desired to make the TV screen comfortably visible.

FIELD OF THE INVENTION 
The present invention relates to a TV receiver which a user can, by remote 
control, rotate, tip, tilt, and move left and right or up and down as 
desired. 
DESCRIPTION OF THE PRIOR ART 
Conventional TV receivers are available in a variety of designs and 
appearances, but the viewer (user) cannot freely move the receiver back 
and forth, tip, tilt or adjust up and down or right and left, as desired, 
using a remote control. Therefore, when the user intends to switch the 
direction or movement of the traditional TV set, he/she has to move the TV 
set itself by him/herself or manually push or pull the supporting rack 
which is provided with a caster. This results in 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, cannot readily be overcome. 
Consequently, manufacturing companies as well as general consumers have 
longed for a hi-tech TV receiver than can, by remote control, be adjusted 
for convenient viewing. 
SUMMARY OF THE INVENTION 
The invention is designed to minimize the inconveniences of using 
conventional TV sets and to offer a high technological TV set, in which 
the TV is the head portion including CRT-tube and a body portion has 
installed therein driving equipment which adjustably supports the head 
portion. The head portion is connected onto the upper part of the 
supporting body position so that only the head can pan over, tilt up and 
down, and move upward and downward by operation of the driving equipment 
in a sequence. 
Therefore, when a viewer steps out of vista (visual range), e.g., 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 cannot be seen from the kitchen, the viewer can remote-control it 
back and forth and move it left and right to make the TV set visible. Even 
in a lying- or-leaning position, the viewer can remote-control the head, 
on a dolly, in and out or pan left and right to a certain angle and have 
the best possible viewing condition for him/herself. 
This hi-tech TV invention makes it possible for a user to view the screen 
from any angle and any direction by remote-controlling the receiver 
itself. 
The supporting frame (the body) of the moving TV receiver consists of a 
fixed frame and a fixing member to which the motor, electronic clutch, 
caster and driving wheel are mounted with a sprocket, chain, sector gear 
and screw shaft. These elements are combined with driving gear on which a 
transmission shaft and driving shaft are connected to the head portion 
above the body portion, and these are controlled to shift the mobile TV 
set in every desired direction. 
When necessary, in a preferred embodiment of this invention, a viewer can 
pan only the head or TV portion left and right at a selected angle within 
a lateral angle of 60 degrees, incline and decline within a range of 40 
degrees, tilt up and down at 15 degrees and 5 degrees, and move up and 
down within a range of 200 mm in height, 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 
As shown in FIG. 1, the upper portion of the moving TV receiver is head 
portion 2 in a global form similar to human head. The lower portion body 
portion 3, of which the internal space accommodates a plurality of driving 
and adjustment elements. Back cover 6 has ventilating openings 5 in it 
and, with the front cover 7, forms the global head 2, and a circular 
speaker 8 is installed at each side. A supporting cover 37, designed to 
prevent leaving an opening when controlling to pan or tilt head 2, is 
provided between the head 2 and the body 3. Below body 3, casters 11, 11' 
are installed on a diameter perpendicular to the driving wheels 10, 10' of 
the driving shafts 22 of the driving gear mechanism. On body 2, an AFT and 
A/V terminal plate 12 is installed to connect to an antenna cord or a 
terminal of a video tape recorder. Along the power cord 13 connected to 
the body 3, a winding device 15 may be provided, allowing the TV set to 
easily move back and forth and right and left. The overall appearance is 
thus designed to make automatic winding of cord 13 possible. 
As best seen in FIGS. 2, 3 and 4, the space 4 within the body 3 supporting 
the head 2 of the moving TV receiver 1 contains a fixed frame with a 
driving mechanism 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. A wheel is installed at each side of a driving shaft 
fixed boss. Driving shaft 22 has a magnetic clutch 19 and gear 21 
installed thereon to control an applied driving force instantaneously. 
This driving shaft is preferably divided into two driving shafts 22, 22' 
centered on the magnetic clutch 19 on it. See FIG. 4. Under the fixed 
frame 16 of body 3, a transmission shaft fixed boss 17, 17' supports 
transmission shafts 23, 23' with another magnetic clutch, 19a, installed 
therebetween. A driving gear 24 engages the gear 21 on the driving shafts 
22, 22' to one of transmission shaft portions 23, 23'. A driving sprocket 
20a is built for continuing movements of vertical sprocket 20 and the 
chain 25 connecting them. Beside this, another sprocket 20b is installed 
to reduce the driving torque on the driving shafts 22, 22'. The 
transmission shaft portions 23, 23' are also divided into two by the 
magnetic clutch 19a. The driving shafts 22, 22' and the transmission 
shafts 23, 23', by activating of the electronic clutches 19, 19a on the 
respective shafts by control of a printed circuit board within the body 3, 
causes the shafts to engage and disengage to control and to deliver a 
driving force to adjust the TV receiver position. 
Underneath the fixed frame 16 in body 3, the casters 11, 11' are located on 
a live perpendicular to a line between the driving wheels 10, 10' on each 
side of the driving shafts 22, 22' and 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 casters 11, 11' make contact with a 
supporting surface to move the entire TV receiver 1 back and forth, or 
left and right, by rotating movement of the casters 11, 11' following the 
driving wheels 10, 10' rotating by movement of the driving shafts 22, 22' 
and the transmission shafts 23, 23' activated by the driving elements 
installed in body 3. 
As shown in FIG. 2, the upper portion of the fixed frame 16 in space 4 of 
body 3 has centered therein a perpendicular transmission shaft 26 
connected to the lower side of the head 2 by a foot step bearing 27. 
On opposite sides of foot step bearing 27 are provided motors M2 and M3. 
Small sprockets 28, 28a are installed on each motor's shaft. The small 
sprocket of motor M2 is connected to sprocket 20b by chain 25a around the 
transmission respective shafts 23, 23' below fixed frame 18 in space 4 of 
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 
moving TV receiver 1 in order to connect itself to a sprocket 20c on the 
perpendicular transmission shaft 26. Transmission shaft 28, is disposed 
perpendicular to foot step bearing 27 at the center of the fixed frame 16, 
and can pan only the head portion 2 of the moving TV receiver 1 at a 
particular or specified angle to left and right. 
On the upper portion of the perpendicular transmission shaft 26, at the 
center of the fixed frame 16 of space 4, connected to the lower portion of 
the upper head 2 of the moving TV receiver 1, is provided a revolving disc 
29. Fixing members 30, 30' are formed at each side thereon, and a motor M1 
is installed between the fixing members 30, 30' to the revolving disc 29 
and has a small sprocket 28b on its shaft. Extending between members 30, 
30' on revolving disc 29, as shown in the FIG. 3, is a rotating shaft 31, 
and a sprocket 20d thereon is connected to small sprocket 28b on the shaft 
of a motor M1 installed on the revolving disc 29 by a chain 25c. 
Another sprocket 20e is built at the center of the rotating shaft 31, 
designed to engage a 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, 
per FIG. 3., rotating rollers 33, 33', 33", 33"' are installed to be hung 
on the upper and lower portions of the supporting members 36, 36' to 
cooperate with the fixed disc 35 fixed to the fixed rib 34 of the upper 
head 2. 
When the sprocket 20e at the center of the rotating shaft 31 engages with a 
chain rack 32 fixed to the lower head 2, control is exercised on the angle 
at which head 2 can decline left and right by the rotating movements of 
the Motor M1 on the revolving disc 29. 
Also, between the lower portion of fixed rib 34 on the lower side of the 
fixed disc 35 (which supports the head portion 2 while being fixed onto 
fixed rib 34 inside the lower portion of the head 2) and body 3, a 
supporting cover 37 is connected to the fixing members 30, 30' supporting 
the head 2 at its lower side to prevent a space 38 of the fixed disc 35 
from being open to the outside. 
On the extreme inside supporting cover 37, built between the head portion 2 
and the body 3 of the moving TV receiver, limit switches (LM1) (LM2) are 
installed to control the maximum angle by which head portion 2 declines 
left or right. 
As best seen in FIGS. 3, 4 and 7 the moving TV receiver comprising the head 
2 and the body portion 3. On the lower face of the fixed frame 16 of inner 
space 4, there are provided transmission fixed bosses 17, 17', 17", 17"' 
as well as driving shaft fixed bosses 18, 18', 18", 18"' integrally formed 
with each other. The driving shaft fixed bosses 18, 18', 18", 18"' are 
fitted with driving wheels 10, 10' on the ends of driving shafts 22, 22' 
and also with clutch 19, sprocket 20 and driving shafts 22, 22' which are 
equipped with a vertical gear 21. These driving shafts 22, 22' are 
separated by clutch 19. The transmission fixed bosses 17, 17', 17", 17"' 
support with the transmission shafts 23, 23' with the center thereof 
equipped with a clutch 19a. On one side of the transmission shafts 23, 23' 
the vertical gear 21 is engaged to a driving gear 24. On the other side, a 
driving sprocket 20a is connected to the vertical sprocket 20 on the 
driving shafts 22, 22' by a chain 52a. Next to sprocket 20a is a sprocket 
20b which sends a movement to the driving shafts. The transmission shafts 
23, 23' are also separated by the central clutch 19a for the driving 
shafts 22, 22' and the transmission shafts 23, 23' to activate the 
clutches 19, 19a on both shafts using the control from the print circuit 
board in the space room 4. Also installed are casters 11, 11'. In doing 
so, the body portion 3 is placed below the head 2 so that only the driving 
wheels 10, 10' and the casters 11, 11' contact the floor when the TV 
receiver is placed thereon. Thus, as the driving wheels 10, 10' rotate 
according to the movement of the driving shafts 22, 22' and the 
transmission shafts 23, 23', the casters 11, 11' rotate enabling the 
moving TV receiver 1 to move back and forth and left and right. 
Between the head 2 and the body portion 3 is provided a moving member 39 
which provides up and down movement installed. The upper half thereof 
supports the lower side of the head 2 and its lower half extends into the 
space 4 of body portion 3. 
Inside the moving member 39, a fixed member 40 is installed, forming sector 
arms 41, 41' on its 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 44, a semi-circular cover 45 is placed in order to 
cover a gap between the head 2 and the moving member 39. Sector gear 43, 
installed on one side of the sector shaft 42, is mutually engaged to the 
spear gear 46 which is provided on the shaft of a motor shaft M5. This 
mechanism is to control the tilting movement of the head portion 2 as the 
sector gear 43 rotates according to the rotation of motor M5. 
Also, on one side of the moving member 39 inserted between the head and the 
body portion of the moving TV receiver another motor M6 is installed 
facing downward. A small sprocket 28c is fixed to the end of the motor 
shaft where 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 by chain 25d. As shown in FIG. 10, a double-row thrust 
bearing 48 is installed on the lower half of the fixed shaft 47. Below 
this structure, a screw shaft 49 is suspended for free rotation. On the 
screw shaft 49, which can separately operate with the help from the 
double-row thrust 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 keyway 50 is provided with a key (not shown) which 
will guide the up and down movement of the screw shaft 49. 
A 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 thrust bearing 54 is installed with its upper side 
provided with a sprocket 20g which forms a screw thread 55 that is 
connected to screw shaft 49 as shown in FIG. 12. This sprocket 20g is 
linked by a chain to the small sprocket 28d which is installed on motor M4 
which is facing upward while installed on one side of supporting member 
51. Thus, as the motor M4 revolves, the sprocket 20g on the screw shaft 49 
rotates, enabling the screw shaft 49 to move up and down. 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 4 which contains the moving elements inside 
it, limit switches LM5, LM6, LM7, LM8 are installed to control the range 
of the tilting angle and height of up and down movement of the head 
portion 2. 
Following hereinbelow is a description of how to operate the present 
invention. 
When the viewer intends to move the moving TV receiver while watching the 
TV, the viewer can turn on the power key on the TV receiver. Then, a start 
signal "H" sent by a motor interrupt port interrupts the electric power 
that is supposed to go to the motors M1, M2 and M3 respectively. As the 
next step, a relay (Ry1) coil of the motor interrupt driven portion A10 is 
excited, closing the related contacts "a1" and "a2." See FIG. 19A-19C. 
Here, the electric power stays on the contact "a" which is commonly shared 
by A11, A12, A13. The same power also stays on the No. 1 pin commonly 
shared by the speed controllers SC1, SC2 and SC3. 
As it is, when the viewer (user) pushes the mode selection button 57', 
which directs back and forth movement of the TV receiver 1, the signal as 
shown by FIGS. 19A-19C is sent to the transistor Q4 via diode D5, 
resistance R5 and condenser C4 from micom output port C. Simultaneously, a 
separate power flow 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 same time, the 
contact "a" at Ry3 is closed, sending an alternating current (AC 
hereinafter) to the contact "a" of battery driven relays (Ry7) and (Ry8). 
If the viewer pushes the button (v) among the movement selection 
buttons:(&gt;) (&lt;) (v) (), the signal decided by the output port G excites 
the Ry7 coil, closing the contacts a1, a2 and a3. See FIG. 13A. The same 
power through al is sent to the board 2 of the speed controller Sc2 and 
the clutch 19a. 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, causing the shaft of motor M2 to rotate (turn). This 
motor shaft of M2 is linked to the sprocket 20b to the transmission shaft 
23 and is fixed to the lower side of the fixed frame 16 of the space room 
(4). At the same time, the magnetic clutch 19 on the driving shaft 22, 22' 
is provided with power while the magnetic clutch 19a on the transmission 
shaft 23, 23' is set off by power provided by the contact of Ry7. In 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. 
The driving shaft 22 revolves as the driven sprocket 20 connected to the 
sprocket 20a revolves. The other driving shaft, 22', turns in the same 
direction with the driving wheels 10, 10' on the ends of driving shafts 
22, 22', allowing the entire receiver 1 to move forward as illustrated in 
FIG. 17. 
The viewer can release the movement selection button (v) when the receiver 
has moved as he/she desired. Then, the signal from 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, receiver 1 
also stops moving, with clutch 19a being able to connect the separated 
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 signal from the micom output port 
C, he/she can push the button (), which will be sent to the transistor in 
the relay driving portion A17 for direction switching mode by way of D15, 
R14 and C11. In the mean while, the relay Ry8 is excited by the 
independent power Vcc, and the contacts a1, a2 and a3 are closed. The AC 
power through a1 is sent to the pin No. 2 of Sc2 and the magnetic clutch 
19a. The power readjusted by the variable resistance within the speed 
controller is again transmitted to the reverse terminal 02 and then to the 
motor M2. 
Contrary to the movement mentioned above, the motor M2 installed on the 
upper side of the fixed frame 16 counter-revolves while the clutch 19 of 
the driving shafts 22, 22' drives them as one shaft so that power 
transmission is made possible. Clutch 19a on one side of transmission 
shafts 23, 23' separates the shafts with magnetic repulsion, 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 
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, linked to the above-mentioned sprocket by the chain 
25, rotates and causes driving shafts 22, 22' to rotate in the opposite 
direction. 
When the driving shafts 22, 22' are united as one by the clutch 19, they 
turn in the same direction as the transmission shaft 23, which in turn 
operates the driving wheels 10, 10', allowing the receiver 1 to move 
backward as shown in FIG. 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 motor M2 while the contacts a1, a2 and a3 of the 
relay driving portion A17 and relay Ry8 open. 
Likewise, the receiver 1 stops moving backward while at the same time the 
other transmission shaft 23' which was separated from the shaft 23 become 
united therewith. 
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 multiplexer through the diode 3, [3], resistance [2] and condenser 
[2], starting from the micom output port B. ([ ] is not shown). 
Simultaneously, an independent power (Vcc) is sent to the transistor [2] 
and [3] via the resistance [3], [4], keeping them equipotential to each 
other. Then the inverted signal excites the relay Ry2 coil of the motor 
driving portion 11. 
Here, the contacts a1 and a3, which are for direction selection mode, are 
provided with the same signal, as the contact "a" at the relay Ry2 is 
closed. 
In order to move the receiver to the right, the viewer can push the 
selection mode button (&gt;) out of the four selection modes (v) (&lt;) () (&gt;). 
Then, the signal from the micom output port G is sent to the driving 
portion (A16) through D13, R13 and C10. 
At the same time, the relay Ry7 is activated, closing the contacts a1, 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 19, producing 
magnetic repulsion. 
However, since the relay driving portion A17 is in a passive state, contact 
a3 at Ry8 remains off, while the clutch 19 is united by the magnetism, 
connecting the transmission shafts 23 and 23'. 
As the contact a1 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 4 separates 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' throughout the chain 25a. As the shafts 23, 
23' turn, the driving sprocket (20a) on the same shafts also turns, 
driving the vertical sprocket 20 which is liked to it by chain 25. 
Finally, the rotation of the driving shaft 22 causes the driving wheel 10 
to turn clockwise. 
The rotation of the transmission shaft 23 is sent to the driving gear 24 by 
way of clutch 19a, counter-rotating (counter clockwise) the driven gear on 
the driving shaft 22' which is mutually engaged to the driving gear 21. A 
the driving shaft 22' and driving shafts 23, 23' turn in the same 
direction, the driving wheel on other end rotates counter clockwise. The 
driving wheels on the driving shafts 22, 22', which are divided by clutch 
19, rotate in opposite directions to each other, thus being able to turn 
360.degree. to the right, and the viewer can release the selection button 
(&lt;) when he/she gets the 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 B 
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 relay driven portion (A16) for selection mode allows 
receiver 1 to move forward simultaneously as it turns 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 1 
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 receiver 1 and, by 
clutch 19 on the shafts 22, 22', return to its previous state. 
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 driving portion All and the relay Ry2. Afterward, when he/she 
pushes the button (&lt;), the signal from the micom output port H is sent to 
the relay driven portion for selection mode through D15, R14 and C11, 
closing the contacts a1, a2 and a3 with the relay (Ry8) coil being excited 
by independent power Vcc. 
The AC power from the contact a1 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 transferred to the reverse terminal 02 and 
then to the above mentioned motor M2 through the contact a2 at Ry8. 
Then the motor starts turning in the reverse sense. Thus, the motor M2 
provided with the transmission shafts 23, 23' installed in the upper side 
of the fixed frame 16 of space 4 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 
receiver 1 itself turns 360.degree. to the left. When the viewer releases 
the selection button (&lt;) after receiver 1 reaches the desired angle he/she 
desires the signal from the micom output B makes the motor driving portion 
all to stop all its movement. 
In 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 relay Ry8 at the 
relay driving portion for selection mode and also remains in a passive 
state. 
When the viewer pushes the button for upward movement, the signal from 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 to start moving back, finally allowing the receiver itself to 
move to the left as shown by FIG. 18. 
When the viewer releases the selection button (&lt;) as receiver 1 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 receiver 1 to face forward, the viewer can push the button 
(&lt;) (&gt;) for selection mode on the remote control (56), and receiver starts 
turning left and right. 
With the receiver turned 90.degree. to be facing the front side, releasing 
the direction button (&lt;) (&gt;) fixes the receiver to the front side. 
As described above, at the time of the receiver's movement the power cord 
or cable 13 connected to the receiver is automatically wound or unwound in 
proportion to the receiver's movement by the winding machine on the floor 
and the power cord 13 is simultaneously and automatically positioned. 
The length of power cord 15 is optionally set in accordance with the 
maximum moving range of the receiver and is wound with the winding machine 
for use. 
Another preferred embodiment will now be described. In order to move the 
head portion 2 to the left or 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. See FIG. 13A. The signal is transmitted to the 
multiplex PM3 through the diode D7, resistance R8 and the condenser C2 at 
the unillustrated output port of the micom. 
At the same time, a separate flow of electric power (Vcc) is transmitted to 
the transistor Q7 of the motor-driving portion A13 through resistance R9, 
R10, to secure the same-level electric potential and to reverse the signal 
and to excite the relay Ry4 coil of the motor driving portion A14. 
Then the contact point "a" of this relay Ry4 is closed and the AC 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 a1 of the 
driving portion A18, A19 for selection mode. 
Thereafter, pressing the direction button for the right (&gt;) among the 
direction buttons (&lt;) (&gt;) () (v) of the remote control 56 transmits the 
power to the transistor Q13 of the relay driving portion for selection of 
direction A15 from an output port F (not shown) of the micom through the 
diode D19, resistance R16 and the condenser C13. Hence, separate power 
(Vcc) is transmitted to the relay Ry10 coil through the limit switch LM2, 
and the coil is excited. 
At the same time, the contact points a1, a2 are closed and AC power is 
transmitted through the contact point a1 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 conversion circuit B12 
through the contact point a2 of the above relay Ry10. 
Motor M3, fixed at the fixing frame 16 of the upper portion of the vertical 
transmission shaft 23, 23' in inner space 4 of lower body portion 3 
rotates clockwise, turning the small sprocket 28 stuck on the motor. Then, 
movable sprocket 20c of the vertical transmission shaft 26 installed on 
the footstep bearing 27 of the fixing frame 16's center-upper portion and 
linked with the small sprocket rotates clockwise and the vertical 
transmission shaft 26 also rotates. 
Revolving disk 29 attached to the vertical transmission shaft 26 rotates 
and both of fixing members 30, 30' on disk 29 also rotate to turn the 
fixed disk 35 integrated in a single body on fixing members 30, 30' and 
attached to head portion 2 in the direction of movement of the vertical 
transmission shaft 26. 
According to the movement of the fixed disk 31, only the head portion 2 of 
the receiver 1 rotates in the same direction, say to the right. 
When head portion 2 moves as much as the viewer wants, he should release 
the direction button for the right (&gt;) on the remote control 56. Then, 
motor 13 stops and head portion 2 is positioned as wanted. 
Even though the viewer continues to press the direction button for the 
right by mistake, head portion 2 rotates no more than 30.degree.. That is, 
in case the head portion 2 reaches the maximum turning position and the 
lower portion of the head portion 2 turns to the maximum, the limit 
switches LM3, LM4 installed at both sides in the lower portion of head 
portion 2 turn off, to end movement of the relays Ry9, Ry10 and to bring 
the motor M3 to a standstill. 
Therefore, in spite of the viewer's mistaken continued pressing of the 
direction button 37' for the right on the remote control 56, the motor M3 
is stopped by the limit switches LM3 LM4 installed in the lower portion of 
head portion 2 and the head portion 2 is controlled not to move beyond the 
maximum moving angle of 30.degree.. 
The above-described mechanism enables the head portion 2 of receiver 1 to 
be remote-controlled and to move to the right as far as the viewer wants 
within the range of 30.degree.. 
Likewise, when the viewer wants to move the head portion 2 of receiver 1 to 
the left, he should press the direction button (&lt;) among the direction 
buttons (v) () (&lt;) (&gt;). 
Then the signal from the output port (E) often micom activates the 
direction-selecting relay transmission portion A18 in the opposite way of 
the previous case and the power through the contact points a1, 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 4 of body portion 3 clockwise. It also rotates the 
fixing members 30, 31' and the fixed disk 35 anti-clockwise which, in 
turn, turns the head portion 2 to the left. 
When the head portion 2 has moved to the left properly for visibility, the 
viewer should release the direction button (&lt;) of the remote control 56, 
which stops the motor M3 and the movement of the head portion 2. In that 
way, head portion 2 moves to the left for the viewer's visibility within 
the range of 30.degree.. 
Accordingly, the head portion 2 of receiver 1 moves freely to the right or 
left within the maximum range of 60.degree. by the remote control, to 
secure the viewer's visibility. 
A third embodiment is described hereinbelow. When the viewer wants the head 
portion 2 of the receiver 1 to lean toward the right or left during 
watching of the television, he should press the inclination button 57, the 
lowest of the mode selection buttons 57, 57', 57" as shown in FIG. 13A. 
With that action, the mode selection is transmitted to the multiplex MP1 
at an output port B (not shown) of the micom through the diode D3, 
resistance R3, R2 and the condenser 2. 
At the same time, a separate power (Vcc) is transmitted to the transistor 
Q2 through resistances R3, R4 and transistor Q3 of the motor transmission 
portion A11, to make the potential thereof the same and to reverse the 
signal, which excites the relay Ry2 coil of the motor driving portion A11. 
Then, the contact point a2 of the relay Ry2 is closed and the waiting AC 
power is induced to the relay Ry5 contact point "a" of the 
direction-selecting relay driving portion A14 and to relay Ry6 contact 
point "a" of the direction selecting relay driving portion A15. 
At this moment, if the viewer presses the direction button to the right (&gt;) 
among the direction buttons (&lt;) (&gt;) () (v), a signal 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 D11 
resistance R12 and the condenser C9, while separate power (Vcc) is 
transmitted to the relay coil Ry16 through the limit switch LM2. 
Then, the coil Ry16 is excited and, simultaneously, the contact points a1, 
a2 are closed. The power through the contact points a1 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 
direction-reversing terminal 02 of the motor conversion circuit B10 
through the relay Ry6 contact point a2 and is transmitted to motor M1. 
Motor M3, fixed at the revolving disk 29 of the upper portion of the 
transmission shaft 26 in the inner chamber of lower body portion 3 rotates 
anti-clockwise, and 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. 
Then, engaging with the sprocket 20e turning anti-clockwise, the chain rack 
32 integrated in a single body at the bottom side of the fixed disk 35 of 
the lower portion of head portion 2 moves in engagement with sprocket 20e 
and rotates to the left, which makes the head portion 2 lean toward the 
right side and rotate. 
As this juncture, the round-type supporting members 36, 36' of the fixed 
disk 35 adjoins and moves among the revolving rollers 33, 33', 33", 33"' 
on the lower fixing member 30, 30', as shown in the illustration FIG. 2. 
This prevents the fixed disk 35 from rattling during turning of the 
leaning head portion 2 for a smooth movement, and also acts as a sliding 
guide for the fixed disk 35. 
When head portion 2 has leaned toward the right side as much as the viewer 
wants, releasing of the direction button (&gt;) of remote control 56 reverses 
the signal from the output port of the micom, to open contact points a1, 
a2 of the direction-selecting relay driving portion a15 and the relay Ry6 
and to cut the AC power to the motor M1. 
With stoppage of the motor driving, further leaning 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 on the direction 
button (&gt;) of the remote control by mistake, the head portion 2 leaning 
cannot exceed 20.degree. (the range of this maximum angle can be modified 
by the position of the limit switches), for there are installed 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 the designated angle 20, 
the head fixed disk 35 touches the limit switch LM2 and cut the power to 
the relay Ry6 coil by movement of the limit switch LM2, regardless of 
continued pressing of the direction button (&gt;) of remote control 56. 
Consequently, the motor stops owing to the lack of 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 LM1, LM2 installed on the 
supporting cover 37 allows a leaning range of 20.degree.-60.degree. 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 (&lt;) together. 
Then, the signal is transmitted to the transistor Q8 of the 
direction-selecting relay driving portion A14 from an output port E (not 
shown) of the micom through the diode D9, resistance R11 and the condenser 
C8, while separate power (Vcc) is transmitted to the relay (Ry5) coil 
through the limit switch LM1 and the coil is excited. 
At the same time, contact points a1, a2 are closed and the AC power through 
the contact point a1 is transmitted to the No. 2 pin of the speed 
controller SC1. The power is adjusted by a variable resistor (not shown) 
in the speed controller SC1 and flows to the same-direction terminal 01 of 
the conversion circuit B10 and is 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 4 of 
lower body 3 rotates clockwise unlike the previous case, and the turning 
of motor M1 is delivered to the chain rack 32 at the bottom of disk 35 at 
the bottom of head portion 2 through small sprocket 28b, chain 25c and the 
sprocket 20d installed in revolving shaft 31 between the two fixing 
members 30, 30' integrated with the revolving disk 29 of vertical 
transmission shaft 26. Chain rack 32 turns and moves to the right 
following the turning of sprocket 20, which results in head portion 2 
leaning to the left and rotating. 
When the head portion 2 has leaned as much as the viewer wants, he releases 
the direction button (&lt;) of the remote control 56. Then, the signal from 
the output port E of the micom is reversed, which opens the relay Ry5 
contact points a1, a2 of the left driving portion 14 and cuts the AC power 
to the motor M1. 
Consequently, it stops driving of motor M1 and further leaning of the head 
portion. The viewer may thus watch the television with head portion 2 
leaned to the left at an angle wanted by the viewer. 
In this case, the maximum range of the leaning of head portion 2 does not 
exceed the optionally designated angle controlled by the limit switch LM1 
fixed on the supporting cover. 
Meanwhile, the movement of the motor on-off driving portion A10 is obtained 
by pressing the motor on-off button 57', of the remote control 56. It 
excites the relay Ry1 coil of the motor on-off driving portion A10 by a 
signal from the output port "a" of the micom and the AC power is supplied 
to each motor driving portion A11, A12, A13. 
Under these conditions, the motor mode selecting buttons 57, 57', 57" and 
the direction buttons (&lt;) () (v) (&gt;) of the remote control are used to 
control each motor driving system of receiver 1. 
Releasing of the motor on-off button 57 of remote control 56 stops the 
function of the relay Ry1 coil to the motor on-off driving portion A10, 
which cuts the AC 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 for which 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 (&lt;) (&gt;) () 
(v) of the remote control 56 for lifting the head portion 2 of the 
receiver 1. 
Motor M4 on the support member 51 on the fixing frame 16 in the lower 
portion of the inner space 4 of the receiver body portion 3 then 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 engagement with screw thread 55 inside of the large sprocket 20g on the 
sliding screw shaft 49 does not turn, while only the sprocket 20g turns to 
the left together with the single-row bearing 54. 
In this way, 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 keyway 50 of the screw shaft 49 is guided, slides along 
and is 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 thrust 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 member 39. 
Thereafter, it is lifted with connecting frame 44 on a 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 moved upward. 
When the head portion 2 of the receiver 1 has moved upward as much as the 
viewer wants, releasing of the direction button () of the remote control 
56 stops the motor M4 on the support member 51 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. 
Likewise, when head portion 2 of receiver 1 should be lowered down, the 
viewer should press the down-direction button (v) among the direction 
buttons () (v) (&lt;) (&gt;) 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 is turned to 
the right, which rotates to the right the sprocket 20g of 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 into engagement with screw thread 55 inside 
the sprocket 20g and remains unturned. Only the sprocket 20g rotates to 
the right with the single-row thrust bearing 54. 
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 engagement inside the sprocket 20g and is lowered down by the 
turning movement of the sprocket 20g. 
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, while fixing member 40 
fixed in the drum-type moving member 39 moves down. As the connecting 
frame 44 on sector gear 43 connected at the fixed rib 34 under the head 
portion 2 is fixed in as a single body by the sector arms 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 head portion 2 is 
lowered down. As a result, head portion 2 of receiver 1 moves down. 
When the time the head portion 2 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 
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. Thus, 
the moving-down of the screw shaft is completed and head portion 2 of 
receiver 1 moves no more. 
As above, the head portion 2 moves up and down by remote control within a 
maximum range height-adjustment range of 200 mm. Even if the viewer keeps 
the direction buttons () (v) pressed beyond a proper adjustment by 
mistake, the drum-type moving member 39 touches limit switches LM5, LM6 
installed top and bottom inside body portion 3 between the support member 
51 in the body portion 3 and the drum-type moving member 39, when head 
portion 2 is moving upward or downward to the maximum range of 200 mm. The 
motor (M4) on the support member (51) in the inner space 4 stops under the 
built-in circuit control through the movement of the limit switches, to 
keep head portion 2 from moving upward or downward in excess of 200 mm. 
As described above, the viewer may optionally adjust the height of the head 
portion 2 within the maximum range of 200 mm through remote-controlling 
for a better convenience. 
Second embodiment 
When the viewer wants the head portion 2 of the receiver 1 to lean forward 
to 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 FIG. 16. 
Thereafter, in order for head portion 2 to lean forward at a certain 
degree, he should press the direction button (v) which finishes the 
movement of motor M5 installed at the fixing member 40 in the inner space 
of the drum-type moving member 39 under the head portion 2 and stops the 
turning of sector gear 43 going in engagement with spurgear 46. 
Head portion 2 then leans forward no more and the viewer may watch the 
television with head portion 2 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.degree.. 
As limit switch (LM) is installed at the point of the maximum allowable 
forward-leaning range 5.degree., in the upper end of the drum-type moving 
member 39 under semi-circular cover 45 and the connecting frame 44 fixed 
on the fixed rib 34 under the head portion 2, the leaning forward of head 
portion 2 by turning of the motor M5 turning reaches the maximum range of 
5.degree. and then the turning semi-circular cover 45 presses and 
activates the limit switch in the drum-type moving member 39 Hence, 
regardless of continued pressing of the direction button (v) of remote 
control 56, the limit switch (LM) stops the motor M5 on the connecting 
frame and controls the head portion 2 so that it does not lean forward 
more than 5.degree.. 
In this way, the viewer may optionally have the head portion 2 lean forward 
within the range of 5.degree., by operating the lowest of the four 
direction buttons () (&gt;) (v) (&lt;), 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. 
Then, the spurgear 46 on the motor M5 rotates in the same direction and the 
sector gear 43 engaging therewith (installed in a single body with the 
sector shaft 42 on the upper end of the sector shaft 42 on the upper end 
of the sector arms 41, 41' of the fixing member 40) slowly starts to 
rotate anti-clockwise in engagement. 
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 head portion 2, turns in the 
same direction by the sector gear 43 turning in engagement therewith. 
Head portion 2, fixed at the top of the connecting frame 44, rotates with 
the connecting frame 44 and slowly leans forward. 
Here, the semi-circular cover 45 fixed around the connecting frame linked 
to the fixed rib 34 at the bottom of the head portion 2 covers up the rear 
space caused by leaning of the head portion 2 forward and maintains a fine 
appearance. 
At the time head portion 2 has leaned forward as the viewer wants through 
such a mechanical procedure, he should release. 
Likewise, when the viewer wants the head portion 2 to lean backward for a 
certain degree, he should press the direction button () among the 
direction buttons () (&gt;) (v) (&lt;) of the remote control 56. It turns 
anti-clockwise the motor installed on the fixing member 40 in space of the 
drum-type moving member 39 under the head portion 2 through the built-in 
circuit control, in the opposite way compared to that of the previous 
case. 
The spurgear on motor M5 then turns in the same direction (anti-clockwise) 
and the sector gear 43, positioned at the top of the sector arms 41, 41' 
of fixing member 40 and operated by the sector shaft 42, starts to turn 
clockwise in engagement with spurgear 46 of the shaft of motor M5. 
At this moment, the connecting frame installed on the sector gear 43, 
surrounded by the fixed semi-circular cover 45 and fixed on top with the 
fixed rib 34 turns in the same direction (clockwise) in engagement with 
sector gear 43. 
Head portion 2 fixed on the connecting frame thus goes into motion with 
connecting frame 44, which results in head portion 2 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. 
When the head portion 2 of the receiver 1 has leaned backward as far as the 
viewer wants, he should release the direction button () of the remote 
control 56. Then, the motor M5 installed on the connecting frame 44 stops 
and the movement of all the portions linked thereto stop, which finishes 
the leaning of head portion 2. The head portion 2 thus leans backward and 
is positioned as the viewer wants. 
At this time, even though the viewer keeps pressing the direction button () 
of the remote control 56 by mistake, head portion 2 leans backward no more 
than 15.degree. owing to the limit switch LM6. 
As limit switch LM6 is installed at the point of the maximum allowable 
backward-leaning range 15.degree., the head portion 2 leaning backward by 
turning of the motor M5 reaches the maximum range of 15.degree. and the 
puts the limit switch LM6 in motion. The motor M5 on the fixing support 40 
is stopped by the limit switch LM6 and the head portion 2 of the receiver 
1 is controlled not to lean backward more than 15.degree.. 
As above, the viewer may optionally have the head portion 2 lean backward 
within the range of 15.degree.. 
As explained so far, this moving television receiver moves back and forth 
and left and right through remote control at the viewer's discretion, and 
the upper head portion of the receiver itself rotates left or right within 
the range of 30.degree. as the viewer wants. 
Also, the upper head portion may lean toward left or right within the range 
of 20.degree. by operation of the remote control, if necessary, and the 
height of the upper head portion may be adjusted upward or downward within 
the range of 200 mm. Further, the head portion leans forward or backward 
within the range of 5.degree. and 15.degree. respectively. 
Accordingly, in case a viewer wants to watch the moving television receiver 
1 in the kitchen over a meal, after watching it in his bedroom, he may 
move the entire television receiver 1 to a position seen from the kitchen 
by operation of the remote control. In addition, he can remote-control the 
head portion on the body portion to be slanted to a selected degree and to 
rotate left or right by a selected angle. Further, the head portion itself 
may be adjusted to lean forward or backward and moved 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. 
In this disclosure, there is shown and described only the preferred 
embodiment of the invention, but, as aforementioned, it is to be 
understood that the invention is capable of use in various other 
combinations and environments and is capable of changes or modifications 
within the scope of the inventive concept as expressed herein.
