The base end 11b of the frame 11 is perpendicular to the tapered surface, and as shown by the solid line in FIG. It comes into contact with the upper part of the recessed part 3d formed in the lower part of. As a result, the control door 10 is tilted further 20 degrees from the horizontal direction (indicated by θ in FIG. 1), making it easier to press the pair of transparent touch panels 12, 12. In addition, as shown by the two-dot chain line in Figure 1,
When the control door 10 is closed, the vertical surface of the base end 11b of the frame 11 comes into contact with the protrusion 2c on the front side of the recess 2b formed in the base 2a of the VTR main body 2.
The control door 10 stands up and is housed in a recess 3a of the front panel 3 of the VTR main body 2. Further, the pair of metal plates 15, 15 fixed to both sides of the frame 11 are attracted to the pair of machinets 16, 16 embedded on both sides of the recess 3a of the front panel 3, whereby the control door The upright state of the control door 10, that is, the closed state of the control door 10 is maintained.

Each of the transparent touch panels 12 has a glass plate with a plurality of thin film transparent electrodes extending horizontally or vertically as a substrate, and a thin glass plate with a plurality of thin film transparent electrodes extending vertically or horizontally formed on one side. The well-known X-
It is a Y matrix switch (transparent thin input device),
By lightly pressing a predetermined portion of the transparent touch panel 12 with a finger, the VTR 1 can be operated into various modes such as recording, playback, rewind, and stop.

[0010] On the surface of the transparent display panel 13 on the side of the smoked acrylic panel 14, there is a "PO" corresponding to an operation button.
Multiple operation key patterns (operation displays) 17 such as "WER (power supply)" and "REC (recording)" are each printed using printing ink that is a mixture of transparent medium ink (matte) and pearl pigment at a ratio of 100:15. It's printed. Each of the operation key patterns 17 is arranged in a pair of holes 11c, 11c formed at the base of the frame 11, and each of the operation key patterns 17 has a light emitting diode (LED) as a light source that lights up when the control door 10 is opened. ) 18 is projected onto each of the transparent touch panels 12. The pearl pigment used is a composite of mica and titanium oxide, which was developed for artificial pearlescent luster (eg, trade name "Iriodin 210" (manufactured by Merck Japan)).

Further, the smoked acrylic panel 14 is made of acrylic resin with a smoke degree of transmittance of 20%, for example, and due to the difference in contrast with the transparent touch panel 12 and the transparent display panel 13, the control door 10 When the VTR body 2 is closed, the characters 8 and the display 9 on the display section 5 provided on the front panel 3 of the VTR body 2 can be directly seen. Further, when the control door 10 is opened, each operation key pattern 17 printed on the transparent display panel 13 can be projected onto each transparent touch panel 12 by side illumination of each light emitting diode 18.

Since the control door 10 is housed in the recess 3a of the front panel 3, the front appearance of the VTR main body 2 can be made simpler, and the overall design of the VTR 1 can be further improved.

Further, as shown in FIGS. 1 and 3, when the control door 10 is opened, the control door 10 is in a state slightly inclined from the horizontal state. This control door 10
While the frame 11 is opening, a switch (not shown) is turned on and the frame 11 is opened.
A pair of light emitting diodes 18, 18 arranged inside are lit. Due to the lighting of each light emitting diode 18 and the difference in contrast between each transparent touch panel 12, transparent display panel 13, and smoked acrylic panel 14 that constitute the control door 10, the entire control door 10 becomes slightly opaque, and each transparent “REC” printed on the transparent display panel 13 on the touch panel 12
” etc., each operation key pattern 17 appears. Each of the operation key patterns 17 was printed with a printing ink that was a mixture of transparent medium ink (matte) and pearl pigment at a ratio of 100:15, so each of the light emitting diodes 18
When the lights are off, the printed characters of each operation key pattern 17 are inconspicuous and hardly visible, but when each light emitting diode 18 is turned on, the printed characters of each operation key pattern 17 emerge on each transparent touch panel 12 and are very easy to see.

The mixing ratio of transparent medium ink and pearl pigment, which are the raw materials of the printing ink, and the light emitting diode 18
FIG. 5 shows the relationship between the visibility and difficulty of the printed characters of the operation key pattern 17 when the light is off and when the light is on. In Figure 5, 5.10% of pearl pigment is added to 100% of transparent medium ink.
, 15, . The easiness or difficulty of seeing the printed characters of each operation key pattern 17 at the time is indicated by a dashed dotted line C. As a result of the test, in the smoked acrylic panel 14 made of acrylic resin with a smoke degree of 20% transmittance,
If the pearl pigment content exceeds 15 to 100 parts of the transparent medium ink, the relationship between the visibility and difficulty of the printed characters when the light emitting diode 18 is turned on and off is reversed, so that the above B and C are It has been found that it is good to use a printing ink with a mixing ratio of 100:15 of the intersecting transparent medium ink and pearl pigment. Note that this mixing ratio varies depending on the type (color) of the pearl pigment used, the transmittance of the smoked acrylic panel 14, etc.

By pressing the transparent touch panel 12 corresponding to each of the operation key patterns 17, the VTR 1 can be easily operated. As a result, substantially the entire surface of the control door 10 is designed so that the operation key pattern 17 has a size, shape, etc. that is easy to see and use without being influenced by the position and size of the display section 5 of the front panel 3 of the VTR main body 2. The VTR 1 can be freely laid out using the following, and an easy-to-use, low-cost VTR 1 can be provided.

[0016] According to the above embodiment, the control door of a VTR was explained as the door structure of an electronic device.
The electronic device is not limited to a VTR, and it goes without saying that the present invention can be applied to door structures of other electronic devices such as AV devices, and display structures of other display sections of electronic devices. Further, a transparent liquid crystal panel (LCD) may be used instead of a transparent display panel or the like. Furthermore, the light source is not limited to a light emitting diode, but may be other electroluminescence, miniature light bulbs, or the like.
