[0008]

FIG. 1 is a block diagram for explaining a first embodiment of the present invention. In the figure, the same parts as those in FIG. 6 are denoted by the same reference numerals, and description thereof will be omitted. 4 is a light emitting diode drive circuit, 5 is a two-color light emitting diode, 5a is a green light emitting part, and 5b is a red light emitting part. In this embodiment, the FDD 2 has the FDD access indicator 3 shown in FIG.
1, FDD access indicator 3 in FDD2
1 is newly connected to the driving line for driving the LED 1 and the LED driving circuit 4. In addition, the drive line driving the HDD access indicator 32 in FIG. 6 is connected from the electronic circuit main board 1 to the light emitting diode drive circuit 4. The output of the light emitting diode drive circuit 4 is supplied to a two-color light emitting diode 5. The two-color light emitting diode 5 has a green light emitting portion 5a and a red light emitting portion 5b, is sealed with glass or plastic material, and is integrated as one device.

In the above description, the light emitting diode drive circuit 4 is provided separately from the main board 1 of the electronic musical instrument, but may be provided on the main board 1 of the electronic musical instrument. Further, the circuit on the main board 1 of the electronic musical instrument may be changed so that the light emitting diode driving circuit 4 is controlled only on the main board 1 of the electronic musical instrument instead of the connection line from the FDD 2 to the light emitting diode driving circuit 4. Good. The installation position of the two-color light emitting diode 5 can be set at an arbitrary position.

FIG. 2 is a diagram showing a first example of a relationship between an access state and a display state according to the first embodiment of the present invention. When the system is accessing the HDD 3, the green light emitting unit 5a is in a light-up state, and when not accessing the HDD 3, it is in a light-off state. The red light emitting portion 5b is H
Lighting control is not performed depending on whether or not the DD3 is being accessed. When the system is accessing the FDD 2, the red light emitting unit 5b is in a lighting state, and when not accessing, the red light emitting unit 5b is in a non-lighting state. The green light emitting section 5a
Lighting control is not performed depending on whether or not DD2 is being accessed. Therefore, when the system is accessing both the HDD 3 and the FDD 2, both the green light emitting unit 5a and the red light emitting unit 5b are in the lighting state, and the light emission color is orange. When the system is not accessing any of the HDD3 and the FDD2, both are off. As a result, the access state to the HDD 3 and the FDD 2 is changed to one 2
The display can be performed in three colors by the color light emitting diodes 5.

In the relationship between the access state and the display state described above, the HDD access indicator 32 of FIG. 6 and the green light emitting portion 5a of FIG. 1, the FDD access indicator 31 of FIG. 6 and the red light emitting portion 5b of FIG. If the desired luminance can be obtained with the same driving current, the light emitting diode driving circuit 4 is not particularly necessary, and each driving line can be directly connected to the green light emitting section 5a and the red light emitting section 5b. is there. However, it is preferable to newly provide the light-emitting diode drive circuit 4 because the range of choices of the two-color light-emitting diodes 5 can be widened and the brightness of two colors can be adjusted.

FIG. 3 is a diagram showing a second example of the relationship between the access state and the display state in the first embodiment of the present invention. When the system is accessing only the HDD 3, the green light emitting unit 5a is lit and the red light emitting unit 5b
Is off. When the system is accessing only the FDD 2, the green light emitting unit 5a is off and the red light emitting unit 5b is on. The system is HDD3,
When both the FDDs 2 are being accessed, both the green light emitting unit 5a and the red light emitting unit 5b are in a lighting state. When the system is not accessing any of the HDD3 and the FDD2, both are off. The relationship between the access state and the display state described above may be achieved by incorporating a logic circuit in the light emitting diode drive circuit 4 of FIG. In this case, the driving current of each of the green light emitting unit 5a and the red light emitting unit 5b is made different between when one of the green light emitting unit 5a and the red light emitting unit 5b emits light and when both emit light at the same time. , The brightness of orange can be adjusted. Further, the correspondence between the access state and the display color can be arbitrarily determined by the logic circuit.

In the above description, the drive control of the two-color light emitting diode 5 is performed by changing only the hardware of the conventional access state display device that controls the lighting of the display by the flexible disk controller, the hard disk controller, or the like. I made it. Instead,
During the operation control flow of various displays in the electronic musical instrument, by detecting a signal indicating an access state, for example, a signal output from each of a flexible disk controller and a hard disk controller,
The display control shown in FIGS. 2 and 3 can be performed. However, in order to drive the newly provided two-color light emitting diode 5, a circuit change of the main board 1 of the electronic musical instrument is required.

FIG. 4 is a first example of a flowchart of a display control for explaining a second embodiment of the present invention. In S11, it is determined whether or not the HDD is being accessed. If Yes, the process proceeds to S12,
If so, the process proceeds to S13. In S12, green is turned on and the process proceeds to S14. In S13, green is turned off and the process proceeds to S14. In S14, it is determined whether or not the FDD is being accessed. If Yes, red is turned on, and if No, red is turned off. By providing such a flow in the operation control flow of various displays in the electronic musical instrument, the same relationship between the access state and the display state as shown in FIG. 2 can be realized.

FIG. 5 is a second example of a flowchart of the display control for explaining the second embodiment of the present invention. In S21, it is determined whether or not only the HDD is being accessed. If Yes, the process proceeds to S22, and if No, the process proceeds to S23. In S22, green is turned on and red is turned off. FD in S23
It is determined whether or not only D is being accessed, and if yes, S is determined.
The process proceeds to S24, and if No, the process proceeds to S25. In S24, green is turned off and red is turned on. In S25, it is determined whether both the HDD and the FDD are being accessed. If Yes, the process proceeds to S26, and if No, the process proceeds to S27. S2
In step 6, both green and red are turned on, and in step S27, both green and red are turned off. In this case,
The relationship between the access state and the display state can be realized by the same logic as that shown in FIG.

In the above description, F is used as the external storage device.
Although the access state of each of the DD and the HDD is displayed in three colors by the two-color light-emitting diodes, an electronic musical instrument having a plurality of external storage devices may be used.
Similarly, the access state can be displayed by the difference in the color of the common display. As the external storage device, FD
D in some cases. In addition to the HDD and the FDD, an MO (magneto-optical disk) drive and a CD-ROM (C
ohmpact Disk-Read OnlyMemo
ry) A driving device may be used.

In the case where three external storage devices are provided, if they may be driven simultaneously, 2 ³ -1 =
Although seven colors are required, seven colors can be displayed by a combination of light emission of light emitting diodes of three colors of red, green, and blue. It is desirable to display the access statuses of all the external storage devices on one display, but the access statuses of at least two external storage devices may be commonly displayed on one display. The display does not necessarily have to be a package in which light-emitting portions with different emission colors are sealed in one package. A user can see the mixed colors of these by, for example, arranging separate light-emitting diodes and passing them through a milky white glass portion. It may be something that is done.

Further, the display device in which the display colors are multicolored does not need to be a light-emitting diode, but excites and emits a fluorescent material like a fluorescent display tube, or rarely contains xenon as a main component like a plasma display. In the case where the ultraviolet-excited light-emitting phosphor emits light by discharging gas, it can be realized by selectively driving a plurality of light-emitting units provided with phosphors having different emission colors. Alternatively, it can be realized by controlling the display color using a color liquid crystal display device.

In the above description, the access status display device of the external storage device in the electronic musical instrument has been described.
The present invention is similarly applicable to a device having a plurality of external storage devices such as a personal computer and a workstation.

[0020]

As is apparent from the above description, according to the present invention, the installation area of the display device is reduced, and the access state of the plurality of external storage devices can be grasped at a glance. There is. Further, if a two-color light emitting diode or the like is used for the display, the cost can be reduced.
