[Conventional technology]

Traditionally, in electronic musical instruments, multiple functions are assigned to a single switch. In this case, all functions assigned to the switch are displayed on the mounting panel surface of the switch. It is displayed with symbols etc. If a single switch is assigned a single function, If you have multiple features, you can display that feature on the switch, but if you have multiple features, you can Not all functions can be displayed on the switch. For this reason, switches and functions is displayed separately.

0003

[Problem that the idea aims to solve]

By the way, displaying the functions of each switch on the panel makes the panel display complicated. reduce the number of switches by assigning multiple functions to a single switch. Contrary to the simplification, it makes the switch operation difficult to understand. Also, operate the switch If the selected function cannot be recognized from the switch and the switch It is also possible to make a mistake in operation.

0004 Therefore, this invention has multiple display modes to facilitate identification of display modes. The purpose is to provide a display device that

[Means to solve the problem]

That is, the display device of this invention emits light in at least two colors, first and second. a panel portion (6) having a possible light source (62) and at least two display pattern portions; 4) The light transmitted through the panel section is projected onto the display pattern section of the panel section. a projection unit (66) for displaying the image, and a control means for selectively controlling the light emission state of the light source. and at least two display pattern parts of the panel part and a display pattern part and beyond the display pattern part. when at least one of the two outer parts is colored with a color similar to the first color; Both are characterized in that the other is colored in a similar color to the second color.

[0006]

[Effect]

The light source emits light in one color under the control of the control means. This light is applied to the panel , passes through a display pattern consisting of colors similar to the emitted light color of the light source, and displays colors that are not similar. As a result, part or all of that light is blocked, and the display pattern is projected on the projection unit. be done. Therefore, it is difficult to visually identify the display mode from the display obtained on the projection unit. I can do that.

[0007] Therefore, for example, if this display device is used to display the functions of the controls, the function display can be simplified. Along with the simplification, the function display becomes easier to identify, the reliability of function selection increases, and the operation becomes easier.

【Example】

FIG. 1 shows an embodiment of the display device of this invention. This display has a pushbutton switch. An operator 2 having a pair or multiple contacts such as a switch is provided, and this operator 2 are assigned multiple functions, as typified by electronic musical instruments.

[0009] A light source driver 4 is installed that generates a drive output according to the function of the controller 2. There is. This light source driver 4 receives control from the CPU 3 according to the function of the operator 2. The color of the light emitted from the light source 62 of the display unit 6 is controlled by the control signal, and the color of the light emitted from the light source 62 of the display unit 6 is further controlled selectively. It turns on or off. In other words, if multiple functions are assigned to controller 2, In this case, the light source driver 4 generates a drive output according to the number of functions to be switched. configured so that

0010 The display unit 6 is provided with a light source 62, a panel section 64, and a projection section 66. Ru. The light source 62 is composed of at least two or more lamps capable of emitting light. It is assumed that the light color can be switched by the output of the light source driver 4. This light source 62 The emitted light color in the It may also be one that emits multiple colors such as red and green.

[0011] Further, the panel section 64 receives light from the light source 62 and selectively transmits or transmits the emitted color. is installed as a filter to cut off the noise. This panel section 64 is transparent or It is made of a light-transmitting plate such as a translucent glass plate or a synthetic resin plate, and has a mechanical structure on its surface or inside. The display pattern representing the function is formed in the same color as the light emitted from the light source 62.

0012 The projection section 66 projects the light that has passed through the panel section 64 to display a display pattern. In addition to being a means of visualizing it, it was also installed as an operation part for the controller 2. It is made of polished glass, translucent synthetic resin plate, etc.

[0013] FIG. 2 shows a specific example of the configuration of the display unit shown in FIG. The light of this example The source 62 receives red and green colors by the drive output Dr emitted from the light source driver 4. A lamp is used as a two-color light source that emits light. Moreover, the panel section 64 is Consists of two translucent panels 641 and 642, and the panel 641 has a display panel. The letter "A" is displayed in red as the turn 643, and the display pattern is displayed on the panel 642. The letter "B" is drawn in green as 644. The projection unit 66 includes a display screen. A projection surface 660 on which the display patterns A and B are to be displayed is formed.

[0014] According to such a configuration, when a specific function is selected using the operator 2, the light source The driver 4 generates a drive output according to the selected function. This drive output For example, as shown in FIG. 3A, the light source 62 lights up in green. When illuminated, the green light passes through panel 642 and reaches panel 641. panel Since the display pattern 644 of the screen 642 is green, other parts than the display pattern 644 Although it is not possible to distinguish between the minutes and the display pattern 644, the panel 641 displays Since the pattern 643 is red, the display pattern 643 blocks light. That is, , the panel 641 allows green light to pass through except for the display pattern 643. It becomes. Therefore, the green light that has selectively passed through the display pattern 643 is The display pattern 6 is displayed in the green display 661 on the projection surface 660. An image 662 representing 43 is displayed, and this image 662 is used to select with operator 2. be able to identify the functions that are

[0015] Also, when the function of controller 2 is changed, the drive output representing the newly selected function is is output from the light source driver 4, and the light source 62 is driven by this drive output, for example, as shown in FIG. As shown in 3(B), when the red light is emitted, the red light is emitted from the surface of the panel 642. It is cut off at the indicated pattern 644. That is, on the panel 642, the display pattern Red light is transmitted except for the portion 644. Display pattern of panel 641 Since the pattern 643 is red, the display pattern 643 also transmits red light. . Therefore, the red light that has selectively passed through the display pattern 644 is transmitted through the panel 64. 1 and reaches the projection unit 66, and on its projection surface 660, a red display 663 is displayed. An image 664 representing the pattern 644 is displayed, and this image 664 is used to control the operator 2. You can identify the selected function.

[0016] In this embodiment, two functions assigned to one controller 2 are displayed in the display pattern. 643 and 644, and one function display when the light source 62 is turned off. By assigning , three function displays are possible. You can also display the pattern like this When 643 and 644 are arranged so as to overlap each other, the projection plane 660 is one The area for displaying the display pattern 643 or 644 is sufficient, and the area for displaying the display pattern 643 or 644 is sufficient. The aim is to make the system more accessible.

[0017] Next, FIG. 4 shows another embodiment of the display device of this invention. This example uses multiple This enhances the effect of combining display patterns when using two panels. For example, if two panels 641 and 642 are used, each panel 641 and 642 has The display patterns 643 and 644 are displaced so that they do not overlap each other. The turn 643 is set to red, the display pattern 644 is set to green, and the light source 62 is set to have a red light. A lamp 621 and a green lamp 622 are installed. Therefore, the green lamp 622 is turned on. Then, as shown in FIG. 5A, the display pattern 643 appears in the green display 661. An image 662 consisting of a shadow is projected, and when the red lamp 621 is turned on, As shown in FIG. 5(B), from the shadow of the display pattern 644 in the red display 663, A green lamp 622 and a red lamp 621 are displayed. When both are lit, as shown in Figure 5 (C), the color is added by red and green. There are no shadows of both display patterns 643 and 644 in the yellow display 665 obtained. Images 662 and 664 are displayed. Such a video 662 or video 664 or The function switching of the operator 2 is displayed by images 662 and 664.

[0018] In this way, the display patterns 643 and 644 are arranged so that they do not overlap each other. In this case, as shown in FIG. 44, and by doing so, the display unit 6 can be simplified. I can do it.

[0019] Next, modifications of the display device of this invention are enumerated as follows. a. The operator 2 may be configured with a volume other than a switch. In the example, the operation The light source 62 was selectively turned on by using the Sakuko 2 as an on/off switch. , the operator 2 may be a wheel; for example, it may be combined with a center return type volume control. The amount of emitted light may be controlled by In that case, for example, one end is green, If you set the other end to red and the middle point to yellow by adding green and red, you can The positional movement of 2 can be represented by a video display, particularly by a change in color. b. The light source 62 is a combination of red, blue, and green lamps and a corresponding panel part 64. Furthermore, by combining the light amount control of the light source 62, changes in color and brightness can be achieved. It is possible to display multiple functions by In the example, one or two panels are used. Although three or more panels may be used in combination. c. In the embodiment, a projection section 66 is provided integrally with the operator 2, and the projection section 66 is provided with a device. However, it is not possible to provide a projection section 66 on the main panel of the electronic musical instrument. Accordingly, functions may be displayed on the main panel or the like. d. In the above embodiment, the panel was made transparent and the display pattern was colored, but the panel The display pattern may be made transparent by coloring the display pattern. e. In the embodiments described above, the display device was used to display the functions of the controls, but multiple displays may also be used. It can be used for anything as long as it has an indication mode, for example, for the detection of some kind of detection means. The display device may be operated based on the output result.
