The relationship between the upper, lower, left, and right sides will be described with reference to FIG. 1, and the diagonally downward direction from the right in FIG.
The TV 100 is a large television of 20 inches or more and has a weight of 20 kg or more. The TV 100 includes a television main body (display main body) 10 and a metal stand (supported by resin or the like) 20 that supports the television main body 10 from below.

  The television main unit 10 includes a receiving unit 12 that receives a broadcast signal, a printed circuit board on which a control circuit is formed, and a display surface 11 that displays an image corresponding to the received broadcast signal on the front. The receiving unit 12 and the printed circuit board are accommodated in a resin cabinet 13 having an opening 14a formed on the front surface in accordance with the display surface 11. Then, under the control of a control circuit mounted on the printed circuit board, a broadcast radio wave is received or a signal in a predetermined format is input from an external input terminal, and corresponding video and audio are output. The cabinet 13 includes a thin, substantially box-shaped housing body portion 14 in which the opening 14 a is formed, and a convex portion 15 protruding rearward from the rear surface 14 b of the housing body portion 14. A plurality of connection terminals 16 are provided on the lower surface 15 a of the convex portion 15. Here, since the lower surface 15 a of the convex portion is located above the lower surface 14 c of the housing body 14, the connection terminal 16 is hidden when facing from the front of the display surface 11.

  The connection terminal 16 includes a power supply terminal to which a power cord can be connected, a D terminal, a S terminal, a USB terminal, a telephone line terminal (modular jack), an optical terminal, and the like to which a predetermined standard cable can be connected. . The connection terminal may be a digital terminal or an analog terminal. Here, some terminals, such as the D terminal, need to be aligned when connecting cables, and other terminals do not need to be aligned.

The stand portion 20 has a base portion 21 having an upper surface 21b facing the lower surfaces 14c and 15a of the cabinet through a space, and projects upward from the upper surface 21b of the base portion so that the television main body portion 10 is connected to the upper ends 22a1 and 22b1. A pair of square columnar legs 22, 22 (a left leg 22a and a right leg 22b) are provided. Concave recesses 13a and 13b that are recessed upward are formed at the front corners of the lower surface 15a of the protrusions 15, and the upper ends 22a1 and 22b1 of the leg portions are inserted into the recesses 13a and 13b. The John main body 10 is supported by the stand 20.
The lower surface 21a of the base 21 is placed on the upper surface of the installation surface on which the TV 100 is installed. Therefore, when the TV is installed on the floor, the floor is the installation surface, and the base 21 is placed. When the TV is installed on the TV rack, the upper surface of the rack is installed. The pedestal 21 is placed on the surface. Both columnar legs 22a and 22b are positioned to sandwich the plurality of connection terminals 16 in the left-right direction when facing from the front of the display surface 11. In other words, the plurality of connection terminals 16 are disposed at positions sandwiched between both leg portions 22a and 22b in the left-right direction.

  A flat plane mirror (mirror member) 30 is provided on the upper surface 21 b of the base part, and a concave accommodating portion 23 capable of accommodating codes is formed below the plane mirror 30. The plane mirror 30 is positioned between the pair of leg portions 22a and 22b, and is provided in alignment with the position of the connection terminal in the left-right direction when facing from the front of the display surface 11. The plane mirror 30 is made of the same material as that of the pedestal 21, and one side is a substantially rectangular mirror surface 30 a, and the other opposite surface is a non-reflective surface 30 b having the same color as the pedestal 21. Further, the flat mirror 30 has a rod-shaped member 31 and a D-shaped member 33 oriented in the left-right direction fixed to the left and right ends, and is attached to the upper surface 21b of the base portion so as to be rotatable about both members 31 and 33 as a central axis. . The plane mirror 30 makes it possible to view the plurality of connection terminals 16 provided on the lower surface 15a of the convex portion and hidden at the front when viewed from the front of the display surface 11.

As shown in FIG. 4, holes 30 c and d having a D-shaped cross section are formed at both left and right ends of the plane mirror 30. The left and right end portions 31a and 31b of the rod-shaped member 31 are D-cut in a D-shaped cross section. The operation knob 32 has fine irregularities for preventing slippage on the outer periphery, and a hole 32a having a D-shaped cross section is formed on the left end. The rod-shaped D-shaped member 33 has a D-shaped cross section. Here, the hole 30c at the left end portion of the plane mirror 30 and the cross section of the D-shaped member 33 have substantially the same size, and the hole 30d at the right end portion of the plane mirror 30 and the cross section of the left end portion 31a of the rod-like member have approximately the same size. The hole 32a of the operation knob and the cross section of the right end portion 31b of the rod-shaped member have substantially the same size.
Further, a hole 24 a and a through hole (bearing portion) 24 b are formed in the base portion 21 in accordance with the position of the rotation center axis of the plane mirror 30, and the inner diameter of the hole 24 a is slightly larger than the outer shape of the D-shaped member 33. The inner diameter of the through hole 24 b is slightly larger than the outer shape of the rod-shaped member 31.

In order to attach the plane mirror so as to be rotatable with respect to the pedestal, the following may be performed.
First, one end of the D-shaped member 33 is inserted and fixed in the hole 30c of the plane mirror, and the other end of the D-shaped member 33 is inserted into the hole 24a of the base portion. Next, the rod-shaped member 31 is inserted into the through hole 24b of the base portion, and the left end portion 31a is inserted into the hole 30d of the plane mirror and fixed. Finally, the operation knob 32 is attached to the rod-shaped member 31 so that the right end portion 31b of the rod-shaped member is inserted and fixed in the hole 32a of the operation knob. Then, the rod-shaped member 31 is fixed to the plane mirror 30 at the left end portion 31a, and is supported rotatably with respect to the base portion 21 at the position of the central axis of rotation of the plane mirror. The operation knob 32 is fixed to the right end portion 31b opposite to the left end portion of the rod-shaped member 31, and can be rotated around the rod-shaped member as a rotation center. Therefore, the user can rotate the plane mirror by rotating the operation knob 32, which is convenient.

  In addition, a plurality of LEDs 41 capable of emitting light emitted to the plurality of connection terminals 16 are provided on the upper surface 21b of the base portion. As shown in FIG. 6, the LEDs 41 are connected in parallel, the anode side is connected to one end of a tact switch (push button switch) 42, and the cathode side is connected to the ground. The other end of the tact switch 42 is connected to one end of a pull-up resistor 43 having a predetermined resistance value, and the other end of the pull-up resistor 43 is connected to a power supply line (+ E, positive potential) of the DC power supply device 44. Here, the switch operation part 42 a of the tact switch 42 is in contact with the lower side of the D-shaped member 33. The tact switch 42 is turned off when the non-reflective surface 30b of the plane mirror is on the upper side, and turned on when the mirror surface 30a is on the upper side. When the tact switch 42 is turned on, a current flows to each LED 41 through the pull-up resistor 43, and each LED 41 emits light to illuminate the plurality of connection terminals 16. That is, the illumination mechanism of the present embodiment is configured by the respective parts 41 to 43 and the power supply device 44, and illuminates the connection terminal when the mirror surface of the rotatable mirror member is set to the upper side. The connection terminal that is hidden from the front may be dark and difficult to see, but even in this case, the connection terminal is illuminated only when connecting the cables to the connection terminal with the mirror surface of the mirror member approximately upper. Since the connection terminal is prevented from being illuminated by setting the non-reflecting surface of the mirror member to the upper side when not in use, the connection terminal is illuminated efficiently and power consumption can be reduced. The connection terminal is illuminated so that the connection terminal can be easily seen and the cables can be easily connected to the connection terminal.

(2) Television action:
When the user of the TV 100 faces from the front of the display surface 11 of the television main body, the lower surface 15a of the convex portion provided with the connection terminal 16 is above the lower surface 14c of the housing main body 14. The connection terminal 16 is hidden and cannot be seen directly. In particular, the connection terminal 16 of the present TV is sandwiched between the pair of legs 22 and 22 in the left-right direction and is difficult to see, while the present TV is very heavy and is not easy to move or tilt.
Here, a flat mirror 30 that allows the connection terminal 16 to be visually recognized when viewed from the front of the display surface 11 is provided on the upper surface 21b of the base portion. Therefore, the user holds the cables with his hands and puts his hands from the front side to the back side between the two leg portions 22, 22, or puts his hands from the left and right outer sides of the both leg portions 22, 22 from the front side to the rear side. The cables can be connected to the connection terminal 16 while visually checking. Therefore, even for large televisions that are difficult to move or tilt, there is no need to connect cables by hand to the connection terminals on the back of the television. It becomes easy to connect to. In addition, since the mirror member is set to the position aligned with the position of the connection terminal in the left-right direction, the connection terminal can be easily placed in the field of view of the mirror member, and the connection terminal can be easily viewed.

  Further, since the mirror member is provided so as to be rotatable with respect to the base part, as shown on the left side of FIG. 5, when viewing the TV 100 from a relatively upper side of the front surface, the angle of the mirror surface with respect to the horizontal plane is made relatively small. Thus, the connection terminal 16 can be put into the field of view. When the TV is viewed from a relatively front side as shown on the right side of FIG. Can be put into view. In this way, by rotating the mirror member, the connection terminal can be easily put in the field of view of the mirror surface, and the connection terminal can be easily seen, so it is very easy to connect the cables to the connection terminal. It is.

Furthermore, since the non-reflective surface of the mirror member is made of the same material and the same color as the base part, a good appearance can be obtained by setting the non-reflective surface upward when not in use.
In addition, since a concave accommodating portion that can accommodate cords is formed on the upper surface of the base portion below the rotatable mirror member, the cords are provided when extra cords are present. This TV is convenient.

(3) Modification:
By the way, various modifications can be considered for the present invention.
Regardless of whether the television is large or small, other than plasma televisions, liquid crystal televisions, cathode-ray tube televisions, video deck and television integrated devices, DVD playback devices and television integrated devices Various devices are conceivable. Further, the present invention can be applied to a display that does not include a receiving device that receives broadcast radio waves, in addition to the television. Of course, the present invention can also be applied to a display including a receiving device.
The mirror member may be a convex mirror or a spherical mirror. Then, when facing from the front of the display surface, it is possible to see the connection terminal without aligning the position of the mirror member with the position of the connection terminal in the left-right direction, so the area of the upper surface of the base is limited It becomes a suitable structure. Of course, the mirror member may be a concave mirror in order to enlarge the connection terminal and make it easy to see.

  FIG. 7 shows a modification of the illumination mechanism. Also in this circuit, the LEDs 41 provided on the upper surface 21b of the base 21 are connected in parallel, and the cathode side is connected to the ground. A power switch (push button switch) 45 for switching on / off the power of the TV 100 is connected to the power line (+ E, positive potential) of the DC power supply device 44. The switch 45 can alternately switch the power line (+ E) between the conductive state and the cut-off state for each pressing operation from the user. The power is on when the switch 45 is in a conductive state, and the power is off when the switch 45 is in a cut-off state. Series circuits 46 and 47 of resistance elements are connected to the end of the switch 45 opposite to the power supply device 44. Here, one end of a resistance element 46 having a predetermined resistance value is connected to the end of the switch 45, and one end of a resistance element 47 having a predetermined resistance value is connected to the other end of the resistance element 46. The end is connected to ground. The anode side of each LED 41 is connected to the intermediate connecting portion 46 a of the resistance elements 46 and 47.

Since the power switch 45 is in a cut-off state when the power is turned off, no current flows through the resistance elements 46 and 47. Therefore, no current flows through each LED 41, and the LED 41 is turned off. Here, when the switch 45 is pressed to turn on the power, the switch 45 is switched to a conductive state, so that a current flows through the resistance elements 46 and 47. Accordingly, a current flows through each LED 41 and the LED 41 is lit. When the switch 45 is pressed again, the switch 45 returns to the cutoff state and the LED 41 is turned off.
In other words, the illumination mechanism of the present embodiment is composed of the units 41, 45 to 47 and the power supply device 44, and illuminates the connection terminals when the TV is turned on. When connecting cables to a connection terminal that is hidden from the front and is dark and difficult to see, the connection terminal is illuminated by turning on the TV, and the connection terminal is not illuminated when the power is turned off. As a result, the connection terminals are efficiently illuminated and less power is consumed. The connection terminal is illuminated so that the connection terminal can be easily seen and the cables can be easily connected to the connection terminal.

FIG. 8 is a front view showing another modified example of the TV 100, and FIG. 9 is a left side view showing the members 51 to 53 provided on the pedestal 21 in the A2-A2 cross section of FIG. A through-hole (bearing portion) (not shown) that can penetrate the rod-shaped member 51 is formed in the base portion 21 in the front-rear direction in accordance with the arrangement of the second rod-shaped member 51, and the rod-shaped member 51 is formed in the through-hole. Is inserted and supported so as to be movable in the front-rear direction with respect to the base 21. The second rod-shaped member 51 has a large number of gears 51a formed on the upper surface thereof to be a rack gear, and a disk-shaped operation knob 52 is fixed to the front end. On the other hand, a spur gear 53 is attached and fixed to the right end portion of the mirror member 50 such as a plane mirror at the position of the central axis of rotation of the mirror member 50. The spur gear 53 is rotatably supported with respect to the base portion 21, and a gear 53 a that meshes with the gear 51 a of the rod-shaped member 51 is formed around the spur gear 53.
In addition, holes similar to the holes 30c and d of the plane mirror 30 are formed at both ends of the mirror member 50, and the left end of the spur gear 53 is a D-cut portion formed in a D-shaped cross section. A D-shaped member similar to the D-shaped member 33 of the plane mirror 30 is also provided. Then, the D-shaped member that is rotatably supported with respect to the base portion 21 is inserted into the hole at the left end portion of the mirror member 50 and fixed, and the D-cut portion of the spur gear 53 is inserted into the hole at the right end portion of the mirror member 50. When inserted and fixed, the mirror member 50 is rotatably supported on the upper surface of the base portion 21.

  With the above configuration, when the user performs an operation of moving the operation knob 52 in the front-rear direction, the spur gear 53 rotates in conjunction with the movement of the second rod-shaped member 51, and the mirror member 50 rotates. Therefore, it is convenient because the mirror member can be linked and rotated reliably by operating the operation knob back and forth. In addition, since the operation knob is in front of the base, it is easy to operate, which is also convenient in this respect.

Of course, as shown in FIG. 10, a spur gear 63 fixed to the right end of the mirror member 50, a rubber belt 61 meshed with a gear 63a of the spur gear 63, and the belt 61, as shown in FIG. An operation knob 62 engaged with the gear 61a may be provided. The spur gear 63 is rotatably supported with respect to the base portion 21 at the position of the central axis of the mirror member 50, and a gear 61a provided inside the annular belt 61 is connected to a spur gear 61a and an operation knob. It is formed in accordance with 62 gears.
With the above configuration, when the user rotates the operation knob 62, the spur gear 63 rotates in conjunction with the movement of the belt 61, and the mirror member 50 rotates. Therefore, since the mirror member can be linked and reliably rotated by rotating the operation knob, it is convenient. In addition, since the operation knob is in front of the base, it is easy to operate, which is also convenient in this respect.
