Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a translucent display device used for push buttons, panels and the like.

[0002]

[Prior Art]

 For example, a push button of an audio device is manufactured by a two-color molding method, which has two kinds of structures. One of them is a structure in which the illuminated character portion is formed into a broken character, and has an appearance as shown in FIG. 11 and a cross section as shown in FIG. In this structure, first, the translucent member 2 is used as the primary molding to form the cut character 7 on the front surface, and then the non-translucent member 5 is used as the secondary molding to surround the character 7. Form .

The other is a structure in which the illumination character portion is formed into a joint character, which has an appearance as shown in FIG. 13 and a cross section as shown in FIG. 14, and further has a back structure as shown in FIG. In this structure, first, the translucent member 2 is used as the primary molding to form the joint character 1 on the front surface, and then the non-translucent member 5 is used as the secondary molding to surround the joint character 1. Form so as to surround it. In particular, in the case of this joint character 1, since the non-translucent member 5 is separated by the joint character 1 into two parts A and B, the back gate 5 as shown in FIGS. 'Must be formed. FIG. 16 is a rear perspective view of the translucent member 2 after the primary molding when forming a joint character, and FIG. 17 is a rear perspective view of the non-translucent member 5 similarly after the secondary molding. There is.

During button illumination, only the cut characters 7 or joint characters 1 made of a translucent member transmit light, so that character illumination as shown in FIGS. 11 and 13 is performed. Here, since the structure of the broken character 7 is a design giving priority to the processing method, it is unavoidable that the character shape is poor in design. On the other hand, the structure of the splice character 1 is excellent in design because the character shape is prioritized, but since the back gate 5 ′ needs to be formed, the back gate 5 ′ protruding after the secondary molding is cut off. Therefore, the advantages of molding cannot be utilized. If the back gate 5'is left unoccupied, it will take up extra space, which will be a hindrance when incorporating it into an audio device, or foreign matter will occur in the characters due to the back gate shape when the button illumination is transmitted. , There is a strange feeling.

[0005]

[Problems to be solved by the device]

 As described above, the conventional translucent display device has a problem in that, if an attempt is made to adopt a spliced character structure having an excellent design, the merit of molding cannot be utilized and the processing becomes complicated.

The present invention has been made in consideration of the above problems, and provides a transmissive display device which can be easily formed without giving a priority to the design in the daytime and without impairing the function as an illumination character at night. The purpose is to do.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a translucent member having a translucent display portion representing a character or a figure on the same surface, and a translucent display surrounding the periphery of the translucent member and at the front surface. In a translucent display device comprising a non-translucent member having at least two parts separated by a portion, a through hole connecting the two parts of the non-translucent member in the thickness direction of the translucent member is provided. It is characterized in that the non-translucent member formed in this through hole is kept flush with the back surface of the translucent member.

[0008]

[Action]

 Also in the joint character structure, at least two separated parts of the non-translucent member are connected by the through hole provided in the translucent member, and the non-translucent member formed in this through hole is transparent. By keeping the same surface as the back of the flexible member, it is not necessary to cut the back gate.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are a perspective view and a cross-sectional view taken along line X-X of FIG. 1 showing a stage of the primary molding of the translucent display device of the present invention. A translucent member 2 is used to form a joint character 1 on the front surface thereof. To do. At this time, a through hole 3 for connecting the two parts A and B, which are the separated parts of the non-translucent member formed at a later stage, is provided in the thickness direction of the translucent member 2. T indicates the thickness of the translucent member 2 in the primary molding. FIG. 6 shows a rear perspective view of the translucent member 2 after the primary molding. Reference numerals 2a and 2b denote connecting holes with the portions A and B of the through hole 3, respectively.

Next, as shown in FIGS. 3 and 4, the non-translucent member 5 is formed so as to surround the joint character 1 formed by the primary molding, and at the same time, the non-translucent member 5 is formed. 5 is also injected from the connecting holes 2a and 2b to be formed in the through hole 3. At this time, the non-translucent member 5 ′ formed in the through-hole 3 is molded so that the thickness thereof is equal to the thickness T of the translucent member 2 obtained by the primary molding. Try to keep it flush with the back. The non-translucent member 5'formed in this way serves as a back gate, and is positioned on the back surface of the joint character 1 as shown in FIG. FIG. 7 shows a rear perspective view of the non-translucent member 5 after the secondary molding. The non-translucent member 5'will function as a gate for a cutoff character.

Since the push button manufactured as described above is a joint character with a design priority in appearance, the display is as shown in FIG. 8 during the day, and it is visually recognized in comparison with a broken character. The quality can be improved, and a high-class feeling can be created. In addition, at night, by illuminating from the back with the light source 6 as shown in FIG. 10, the display on the front becomes a broken character 7 due to the presence of the back gate 5 ′ as shown in FIG. 9, but the function of illumination is Does not fall.

Therefore, the back gate 5'is not required to be cut as in the conventional case and can be left as it is, so that the merit of molding can be utilized and the manufacturing cost can be reduced. Furthermore, even if the back gate 5'is left, the thickness is the same as the thickness of the transparent member 2 formed by the primary molding, so that it is not projected unlike the conventional case, and thus an extra space is not required. Do not occupy. Therefore, there is no hindrance when incorporated in an audio device. This makes it possible to design with space.

Further, according to the present invention, the contour of the broken character is blurred by the shape difference of the back gate at the time of illumination through the button as compared with the conventional one, whereas the contour of the broken character becomes clearer than the conventional one, which is good-looking. You will be able to make a good display.

[0014]

[Effect of the device]

 As described above, according to the present invention, at least two portions of the non-translucent member separated by the translucent display unit are connected by the through hole provided in the translucent member, and the non-transparent member in the through hole is connected. Since the light-transmitting member is kept on the same surface as the back surface of the light-transmitting member, it is not necessary to cut the back gate, so that the merit of molding can be utilized. Furthermore, design priority can be displayed in the daytime, and display can be performed at night without impairing the lighting function.
