Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a channel display device in a channel selection mechanism of a television receiver using a selection push button switch.

A conventional channel display device of this type includes a plurality of channel selection switches, and a channel display section that decreases points in response to the operation of each push button switch is arranged in parallel to the push button switch and is glued to the display panel. This display panel was placed over the case as a lid.

In this way, in conventional channel display devices, the channel display section is installed separately and in parallel with the push button switch so that the display lamp of the channel display section can be replaced, so the device itself becomes large. This increased the space taken up in front of the television receiver, which prevented the television receiver from becoming more compact.

The present invention was developed in view of the above points, and it not only makes it possible to downsize the device, but also provides a channel display that makes it easy to replace the display lamps that indicate the number of channels selected and whether or not the power is turned on. The device is provided with an outer casing in which a plurality of key top storage sections partitioned by partition walls are arranged in a row, and a side wall of the outer casing that communicates with the key top storage sections. A transparent hole is formed, a plurality of light-transmitting keytops are vertically movably fitted into the keytop storage, and the keytop is formed in the insertion portion of the keytop storage so as to communicate with the transparent hole. an indicator lamp accommodating part that passes through the through hole and is inserted into the indicator lamp accommodating part; and an indicator lamp that is irradiated by the indicator lamp and illuminates the area above the key top accommodating part of the outer casing and the key top. a channel display body inserted between the display lamp accommodating part and a switch body penetrating the bottom of the outer casing so as to come into contact with the bottom of the key top;
The channel display device is characterized in that a lead wire of the display lamp and a lead wire of the switch body protrude in the same direction toward a side of the outer casing.

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is an exploded perspective view showing one embodiment of the channel display device of the present invention, FIG. 2 is a front view of the same embodiment, and FIG. 3 is a sectional view taken along the line -- in FIG. 1 to 3, reference numeral 1 denotes a channel display device, which has a plurality of key tops 3 fitted into an outer casing 2 with an open top, and which can be turned on and off individually by vertical movement of the key tops 3. A plurality of slide switches 4 that turn off, a display lamp 5 that decreases in light in conjunction with the on/off of the slide switches 4, and a channel display that displays the selected channel by illuminating light from the display lamp 5. body 6
It is composed of.

Thus, the outer casing 2 has a line of key top storage areas 8 partitioned by a partition wall 7 formed therein, and through holes 2a are formed in opposite sides of both side walls at positions corresponding to the key top storage areas 8. A through hole 2b is bored at the bottom through which the operating shaft 4a of the slide switch 4 passes, and a regulating wall for regulating the horizontal position of the channel display 6 is provided at the upper end of the partition wall 7. 2c are integrally protruded at predetermined intervals. Furthermore, a locking protrusion 2e that engages with a square hole (not shown) in the board 9 is provided on one side wall 2d of the outer casing 2 in a protruding manner.

Further, the key top 3 is made of a translucent resin such as acrylic or polycarbonate, and a display lamp accommodating portion 10 is formed in the lower part of the key top 3. The key top 3 is fitted into the key top storage portion 8 so as to be movable up and down, and a protrusion 3a protruding from the outer periphery of the key top 3 engages with a through hole 2a of the outer casing 2 to prevent it from coming off.

The operating shaft 4a of each slide switch 4 and the coil spring 4b provided around the operating shaft 4a pass through the through hole 2b of the outer casing 2, and the key top 3 is inserted into the key top storage portion 8. The slide switch 4 touches the bottom of the outer casing 2 and is constantly pushed up.
The outer casing 2 is attached to the substrate 9 with which the outer casing 2 is engaged in a predetermined positional relationship. Further, the channel display body 6 is guided by the regulating wall 2c so as to close the key top storage section 8 of the outer casing 2, and the key top 3 is inserted into the key top storage section 8.
The lamp accommodating portion 10 of the lamp accommodating portion 10 is inserted therethrough. The display lamp 5 is inserted through the through hole 2a of the outer casing 2 and is provided in the lamp accommodating portion 10 so as to be located below the channel display body 6. Note that 2f in the figure is an engaging protrusion that engages with an elastic engaging claw 6a formed on the side of the end of the channel display body 6. Furthermore,
Although not shown, an operating piece is provided that slides in a direction perpendicular to the movement of the operating shaft 4a in response to the press of the operating shaft 4a of the switch 4, and the operating shaft 4a of the selected switch 4 is held at the pressed position. The operating shaft of the other switch that has been in the pressed position is returned to its original position. In the returning position, the operating shaft 4a and the coil spring 4b act to push up the bottom of the key top, and in the pressed position, the coil spring 4b acts to push up the bottom of the key top. The key top is configured to return to its original position by applying force from the chisel.

In the channel display device 1 configured as described above, the outer casing 2 is attached to the board 9, the slide switch 4 is soldered to the pattern of the board 9, the key top 3 is fitted into the outer casing 2, and the display lamp of the key top 3 is housed. The channel display body 6 is inserted into the section 10 from one end in the longitudinal direction of the outer casing 2, and the display lamp 5
After the key top 3 is fitted into the outer casing 2, it is inserted into the lamp accommodating portion 10 from one side wall 2d of the outer casing 2, and the terminals are soldered to the board 9 to be assembled.

Therefore, even when replacing the indicator lamp 5, if the indicator lamp 5 is removed from the board 9, the transparent hole drilled in the side wall of the outer casing can be replaced without removing the other channel indicators 6 or key tops 3. The indicator lamp 5 can be easily replaced through the hole.

As explained above in detail, the channel display device of the present invention has a display lamp accommodating section at the bottom of the key top, and the display lamp and channel display body are inserted into this lamp accommodating section. It is more compact than a channel display device that has two display lamps installed side by side, and even when it becomes necessary to replace the display lamp, there is no need to disassemble the entire unit, and only the display lamp to be replaced can be removed. , which can be easily replaced.
