Abstract

PURPOSE:To prevent an optical disk sub-system device from becoming infeasible to be used caused by the deterioration of a cooling effect and to enhance the reliability thereof by always monitoring the clogging of a filter. CONSTITUTION:The filter 7 which is fitted to an optical disk device and which fetches external air is provided. Besides, a detector 10 which detects the clogging state of the filter which purifies the external air and a display device 11 which executes display based on the signal of the detector 10 are incorporated in a housing.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical disc subsystem device, and more particularly to an optical disc subsystem device with an improved system for purifying air sent to an optical disc device.

0002

2. Description of the Related Art Conventionally, this type of optical disc subsystem apparatus includes, as shown in FIG. It is composed of a power supply device 4, a fan motor 5 for introducing air, and a filter 7, which will be described later. Further, the optical disk device 2 is provided with an optical head 8 and a spindle motor 9. Here, in order to prevent the temperature of the device from rising, the fan motor 5 is used to introduce external air into the device for cooling. In order to prevent contamination, especially to prevent contamination of the lens 8A of the optical head 8, the structure is such that when introduced into the apparatus, the air is passed through a filter 7 provided at the introduction port 6A to remove dust from the air before being introduced into the apparatus. It has become. Note that there was no means for detecting clogging of the filter 7.

[Problems to be Solved by the Invention] The conventional optical disc subsystem device described above does not have a built-in mechanism for monitoring filter clogging, which is a guideline when replacing the filter. In the worst case, data may be destroyed if the temperature of the optical disk device rises, making it impossible to maintain the performance and reliability of the optical disk device.

0004

[Means for Solving the Problems] An optical disk subsystem device of the present invention includes an optical disk device that uses an optical disk medium to read and write information, a control device that controls the optical disk device, a power supply device that drives the system, and a subsystem. In an optical disc subsystem device having a fan motor for feeding external air to prevent a temperature rise in the entire system and a filter for purifying the external air, a detector for detecting a clogging state of the filter for purifying the external air; The device has a built-in display device that performs display based on the signal from the detector.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention. Moreover, FIG. 2 is a perspective view showing the external appearance of this embodiment. Figure 1
In the conventional example shown in FIG. 3, the same reference numerals have the same configuration and function. That is, in this embodiment, a photocoupler 10 for a clogging detector, a clogging monitoring indicator 11, and a mounting member 12 are added.

Next, the main parts of this embodiment will be explained with reference to FIG. A photocoupler 10 of a clogging detector is installed outside the filter 7.
is shown fixed to the mounting member 12 and further attached to the filter 7. When power is turned on to the optical disk subsystem device, the fan motor 5, which prevents the temperature of the entire subsystem from rising, rotates and supplies air to the outside. During this operation, dust adheres to the filter 7. Filter 7
Due to the dust, the amount of reflected light from the photocoupler 10 of the detector is reduced and the generated voltage is also turned off. By inputting this off signal to the control device 3 as an abnormality, the display device 1 is operated via the control device 3 and the filter 7 is operated.
Displays the clogging status.

[0008]

As explained above, the present invention constantly monitors the clogging of the cooling air purifying filter attached to the optical disk subsystem device, thereby preventing the optical disk subsystem device from becoming unusable due to a decrease in the cooling effect. This has the effect of increasing the reliability of the optical disk subsystem device.
