At this time, the control device 3 detects whether or not data is transmitted / received, that is, whether or not the optical disk 11 is being accessed. For example, if the optical disk 11 is being accessed, the first light emitting element 5 is turned on, and if not, the first light emitting element 5 is turned off. For example, when the optical disk 11 is damaged or the like and the recorded information cannot be read, the first light emitting element 5 is controlled to blink.

  Then, the second light-emitting element 7 is controlled in synchronization with the control of the first light-emitting element 5 described above. That is, for example, if the optical disk 11 is being accessed, the control device 3 controls the second light emitting element 7 to be turned on via the output terminal 9, and if not, via the output terminal 9. The second light emitting element 7 is controlled to be turned off. Therefore, in the present embodiment, the first light emitting element 5 and the second light emitting element 7 perform the same light emitting operation.

That is, the lid 23 covers the first light emitting element 5 formed on the front surface of the optical disc apparatus 100 in the closed state. For example, if the lid 23 blocks light, the first light emission is performed. Even if the element 5 performs the light emitting operation, the user cannot grasp it. Therefore, the user cannot grasp whether or not the input / output device controller 21 is accessing the optical disc 11 and whether or not the optical disc 11 is damaged and outputs error information.

  On the other hand, the output terminal 9 formed in the optical disc apparatus 100 is connected to the second light emitting element 7 through the second communication path 6, and the second light emitting element 7 is exposed from the input / output device casing 19. ing. And the said 2nd light emitting element 7 is not covered with the lid | cover 23 which covers the 1st light emitting element 5, as shown in FIG. Therefore, the second light-emitting element 7 that synchronizes with the first light-emitting element 5 in the light-emitting operation can make the user visually recognize the same light-emitting operation as that of the first light-emitting element 5.

  As described above, even if the user cannot grasp the state of the optical disc device 100 by the first light emitting element 5 formed on the front surface of the optical disc device 100, the output terminal 9 synchronized with the first light emitting device 5 is provided. By forming the optical disk device 100 and controlling the second light emitting element 7 from the output terminal 9, the user can accurately grasp the state of the optical disk device 100.

  Further, even when the lid 23 is not formed on the input / output device 200 and the first light emitting element 5 is not formed on the front surface of the optical disc apparatus 100 by design, the second light emitting element is used. By only 7, the user can accurately grasp the state of the optical disc apparatus 100.

  The contents described above can be applied to, for example, a tower type input / output device 250. 3 is a front view of a tower type input / output device (hereinafter referred to as a tower type input / output device) 250.

And the first light emitting element 5. An output terminal 9 formed on the back surface of the housing 1 is connected to the control device 25 through the second communication path 6, and a communication path 15 is connected to the control device 25. Further, for example, the second light emitting element 7 is connected to the output terminal 9.

  More specifically, the control device 25 includes a blinking signal generator 27, and the blinking signal generator 27 is connected to the first light emitting element 5 through the first communication path 4. The blinking signal generator 27 has a function of generating a blinking signal to be output to the first light emitting element 5 from a predetermined condition. The control device 25 includes an output terminal blink signal generator 29, and the output terminal blink signal generator 29 is connected to the output terminal 9 through the second communication path 6.

  Further, the flashing signal generator 27 is connected to a storage device 31 built in the optical disc apparatus 300, and the output terminal flashing signal generator 29 is connected to an output terminal storage device 33 built in the optical disc apparatus 300. . The storage device 31 and the output terminal storage device 33 are composed of, for example, an SRAM (Static Random Access Memory) or a flash memory. The storage device 31 stores blink pattern data for blinking the first light emitting element 5, and the output terminal storage device 33 stores output terminal blink pattern data transmitted to the output terminal 9.

  The blinking pattern data is defined by the firmware when the optical disc device 300 is manufactured, and is stored in the storage device 27 in advance. The data cannot be a blinking pattern that matches the user's preference. However, the flashing pattern data for the output terminal is stored in the output terminal storage device 33 via the communication path 15 from the input / output device 13 or the like arranged outside, and used, or the data saving stored in the optical disc device 300 The output terminal blinking pattern data prepared in advance in the means 35 can be stored in the output terminal storage device 33 according to the user's preference and used.

For example, in the above-described embodiment, the light emitting element is blinked and the state of the optical disk device is grasped by the user's vision. However, any means (notification means) for notifying the user of the driving state of the optical disk may be used. By using a sounding element such as a piezoelectric buzzer as a notification means that indicates the operation status instead, the state of the optical disc apparatus can be grasped by the user's hearing.

  In addition, instead of an input device such as a mouse equipped with a vibration motor, the light emitting element connected from the output terminal is used as a notification means, and the state of the optical disk device is notified by a user's sense of touch by vibrating the vibration motor. You can also.
