[First Embodiment]
As shown in FIGS. 1 and 2, the disk device 2 records and reproduces data on a disk 3, and is used by being externally attached to a personal computer main body constituting a part of a computer system.

  In the disk device 2, a disk reproducing mechanism 5 and a circuit board 6 are incorporated in a case 4. The disk reproduction mechanism 5 includes a spindle motor 7 that rotates the disk 3, a pickup head 8 that records / reproduces data on the disk 3, and a pickup base 9. A turntable 10 on which the disk 3 is mounted is fixed to the drive shaft of the spindle motor 7. The disk 3 has a disk hole 3a formed at the center. The turntable 10 is provided with a chucking head 11 and is inserted into the disk hole 3 a of the disk 3. The chucking head 11 inserted into the disk hole 3a is coupled (adsorbed) to a clamper (not shown) provided inside the case 4, so that the disk 3 is sandwiched between the turntable 10 and the clamper. It becomes a state and can rotate.

  The pickup head 8 incorporates an objective lens 13 that condenses the laser light emitted from the light emitting element on the recording surface of the disk 3. The pickup head 8 is movably held by a holding shaft 14 attached to the pickup base 9. The pickup head 8 is moved in the A direction which is the radial direction of the disk 3 by a known moving mechanism having a motor, a gear and the like.

  The circuit board 6 is provided with a CPU 16 that controls the driving of the spindle motor 7 and the pickup head 8. An exhaust fan 17 is attached to the CPU 16. On the rear surface of the case 4, a plurality of heat radiation holes 4 a are formed at positions facing the exhaust fan 17. The driving of the exhaust fan 17 is controlled by the CPU 16, and the heat generated from the CPU 16 is radiated to the outside of the case 4 by exhausting the air inside the case 4 to the outside of the case 4 through the heat radiation holes 4 a.

  A disc tray 21 is movably attached to the case 4. As shown in FIG. 3, the disc tray 21 is located between the storage position stored in the case 4 when the disc 3 is reproduced and the drawer position pulled out from the case 4 as shown in FIGS. Moving. The disc tray 21 is moved by a known tray moving mechanism 22 having a motor, gears, and the like.

  As shown in FIGS. 1 and 2, the disk tray 21 is loaded with the disk 3, and a recess corresponding to the outer diameter of the disk 3 is formed. An insertion hole 21a through which the spindle motor 7 and the turntable 10 are inserted when the storage position is located is formed at the center of the disk tray 21, and the pickup head 8 is attached to the disk 3 continuously from the insertion hole 21a. An access opening 21b for access is formed.

  A tray insertion hole 4 b into which the disc tray 21 is inserted is formed on the front surface of the case 4. As shown in FIG. 3, when the disc tray 21 is located at the storage position, the tray insertion hole 4b is shielded by the disc tray 21, and when the disc tray 21 is located at the drawer position as shown in FIGS. There is a gap between the tray insertion hole 4b and the disc tray 21.

  On the front surface of the case 4, an open / close switch 26 for opening / closing (moving) the disk tray 21 and an LED 27 are provided. The open / close switch 26 and the LED 27 are connected to the CPU 16. The open / close switch 26 outputs a signal to the CPU 16 when pressed. The LED 27 can be changed to a lighting state, a blinking state, and a light-off state, and is controlled by the CPU 16.

  A position detection switch 31 and a temperature sensor 32 are provided inside the case 4. The position detection switch 31 detects the position of the disc tray 21. For example, a switch piece 31a that can be rotated to the left-side down position in FIG. It has a rotary switch. The position detection switch 31 is disposed below the disk tray 21.

  When the disk tray 21 moves to the storage position, the switch piece 31a of the position detection switch 31 contacts the disk tray 21 and rotates to the right-side down position. The position detection switch 31 outputs a storage signal to the CPU 16 when the switch piece 31a is rotated to the right side position. When the disc tray 21 moves to the drawer position, the switch piece 31a contacts the disc tray 21 and rotates to the leftward position. The position detection switch 31 outputs a pull-out signal to the CPU 16 when the switch piece 31a is rotated to the leftward position. When the disc tray 21 is positioned between the storage position and the drawer position, the switch piece 31a is positioned at an intermediate position between the left-side down position and the right-side down position. The position detection switch 31 does not output a signal to the CPU 16 when the switch piece 31a is located at the intermediate position. The temperature sensor 32 detects the temperature of the CPU 16. A slider that slides according to the movement of the disk tray 21 may be provided, and the switch piece 31a of the position detection sensor 31 may be rotated by the slider.

  Next, the operation of the disk device 2 will be described. As shown in FIG. 3, when the disc tray 21 is located at the storage position, a storage signal is input from the position detection switch 31 to the CPU 16. When the storage signal is input, the CPU 16 enables the exhaust fan 17 to be driven and turns off the LED 27. Further, when the storage signal is input, the CPU 16 determines whether or not the temperature detected by the temperature sensor 32 exceeds 35 ° C. When the CPU 16 determines that the detected temperature exceeds 35 ° C., the CPU 16 drives the exhaust fan 17. When the exhaust fan 17 is driven, the heat generated from the CPU 16 is radiated to the outside of the case 4 through the heat radiation hole 4a. Further, when the detected temperature does not exceed 35 ° C., the CPU 16 stops the exhaust fan 17. In addition, the said temperature can be changed suitably. Further, the CPU 16 may always drive the exhaust fan 17 when the storage signal is input.

  When loading the disk 3 in the disk tray 21, the open / close switch 26 is pressed. As shown in FIGS. 1 and 2, the CPU 16 drives the tray moving mechanism 22 in response to the input of a signal from the open / close switch 26, and moves the disk tray 21 to the drawer position. When the disk tray 21 moves to the drawer position, a drawer signal is input to the CPU 16. In response to the input of the extraction signal, the CPU 16 stops driving the exhaust fan 17 if it is being driven. As a result, when the disc tray 21 is located at the pull-out position and the tray insertion hole 4b is exposed, dust from the outside of the case 4 enters the case 4 through the tray insertion hole 4b by driving the exhaust fan 17. In this way, dust outside the case 4 can be prevented from adhering to the pickup head 8 and the objective lens 13.

  Further, when the drawer signal is input, the CPU 16 determines whether or not the temperature detected by the temperature sensor 32 exceeds 40 ° C. (first predetermined temperature) and 45 ° C. (second predetermined temperature). When the temperature exceeds 45 ° C., the CPU 16 is more likely to break due to the temperature rise. Therefore, it is preferable to warn when the detected temperature approaches the dangerous temperature of 45 ° C. Therefore, when the CPU 16 determines that the detected temperature exceeds 40 ° C., the CPU 16 warns by blinking the LED 27. Further, when the detected temperature exceeds the dangerous temperature of 45 ° C., it is necessary to immediately drive the exhaust fan 17 to lower the temperature inside the case 4. When the CPU 16 determines that the detected temperature exceeds 45 ° C., the CPU 16 issues a warning by turning on the LED 27, and then drives the tray moving mechanism 22 to move the disk tray 21 to the storage position. In addition, the said temperature can be changed suitably.

  When the open / close switch 26 is pressed after the disk 3 is mounted on the disk tray 21 located at the drawer position, the CPU 16 drives the tray moving mechanism 22 to move the disk tray 21 to the storage position.

  When the disk tray 21 moves to the storage position, a storage signal is input from the position detection switch 31 to the CPU 16. In response to the input of the storage signal, the CPU 16 enables the exhaust fan 17 to be driven. When the CPU 16 determines that the temperature detected by the temperature sensor 32 exceeds 35 ° C., the CPU 16 drives the exhaust fan 17.

[Second Embodiment]
The second embodiment of FIG. 4 shows a disk device 40 provided with two fans. In addition, the same code | symbol is attached | subjected to the structural member similar to the thing of 1st Embodiment, and the detailed description is abbreviate | omitted.

  A front vent 4c is formed on the front surface (left surface in FIG. 4) of the case 4, and a rear vent hole 4d is formed on the rear surface (right surface in FIG. 4) of the case 4. Inside the case 4, an intake fan 41 facing the front vent hole 4c and an exhaust fan 42 facing the rear vent hole 4d are provided. Each of the fans 41 and 42 is provided below the disc reproducing mechanism 5. The intake fan 41 sucks air outside the case 4 into the case 4 through the front vent 4c. The exhaust fan 42 exhausts the air inside the case 4 to the outside of the case 4 through the rear vent hole 4d.

  When the disc tray 21 is located at the storage position, the CPU 16 can drive only the exhaust fan 42 and drives the exhaust fan 42 when it is determined that the temperature detected by the temperature sensor 32 exceeds 35 ° C. When the disk tray 21 is located at the drawer position, the CPU 16 can drive both the intake fan 41 and the exhaust fan 42. If the CPU 16 determines that the temperature detected by the temperature sensor 32 exceeds 35 ° C., the CPU 16 and the exhaust fan 41 are exhausted. The fan 42 is driven. When both are driven, the CPU 16 adjusts the intake air amount of the intake fan 41 and the exhaust amount of the exhaust fan 42 to be substantially the same. The intake fan 41 and the exhaust fan 42 may be driven when the disc tray 21 is not located at the storage position, that is, when the storage signal is not input to the CPU 16.

  If the intake air amount of the intake fan 41 and the exhaust air amount of the exhaust fan 42 are substantially the same, the air sucked into the case 4 by the intake fan 41 is exhausted as it is to the outside of the case 4 by the exhaust fan 42, so that each fan When the heads 41 and 42 are driven, no air is vented around the pickup head 8. Thereby, when the disc tray 21 is located at the drawer position, the exhaust fan 42 is driven so that dust outside the case 4 does not enter the case 4 through the tray insertion hole 4b.

[Third Embodiment]
The third embodiment of FIGS. 5 and 6 shows a disk device built-in personal computer main body (referred to as a personal computer main body) 50 that includes a disk device 60 and constitutes a part of a computer system. In addition, the same code | symbol is attached | subjected to the structural member similar to the thing of 1st Embodiment, and the detailed description is abbreviate | omitted.

  In the personal computer main body 50, a disk device 60, a circuit board 52, and a hard disk drive device 53 are incorporated in a main body case 51. The hard disk drive 53 records and reproduces data on the hard disk.

  A CPU 54 and an exhaust fan 55 are assembled on the circuit board 52. The CPU 54 controls the drive of the disk device 60 and the hard disk drive device 53 and is assembled at a position close to the exhaust fan 55.

  The disk device 60 is provided with a disk reproducing mechanism 5 inside the case 4, and the disk tray 21 is pulled out from the case 4 and a storage position (see FIG. 6) stored inside the case 4 when the disk 3 is reproduced. It moves between the drawer positions (see FIG. 5). The case 4 is attached to the main body case 51 so that the front surface thereof is substantially flush with the front surface of the main body case 51. The disc tray 21 protrudes from the front surface of the main body case 51 when located in the drawer position. The disc tray 21 is moved by a tray moving mechanism 22 provided inside the case 4. A disk holding rib 21 c for holding the disk 3 is formed on the disk tray 21.

  The position detection switch 31 provided inside the case 4 outputs a storage signal to the CPU 16 when detecting that the disk tray 21 is in the storage position, and detects that the disk tray 21 is in the drawer position. When this is done, a drawer signal is output to the CPU. A temperature sensor 57 for detecting the temperature of the CPU 16 is provided inside the main body case 51. The disk device 60 and the CPU 54 are connected by an IDE interface or the like, and the storage signal and the extraction signal are output from the CPU 16 to the CPU 54 via the IDE interface.

  On the front surface of the case 4, an open / close switch 26 for opening / closing (moving) the disk tray 21 and an LED 27 are provided. A plurality of heat radiation holes 51 a are formed on the rear surface of the main body case 51 at positions facing the exhaust fan 55. The exhaust fan 55 is driven by the CPU 54 and radiates heat generated from the CPU 54 to the outside of the main body case 51 through the heat radiating holes 51a. When the exhaust fan 55 is driven, the air inside the case 4 flows into the main body case 51 through the connector connection opening formed in the case 4 and is exhausted to the outside of the main body case 51 through the heat radiation holes 51a. Thereby, the heat generated from the CPU 16 inside the case 4 can be radiated to the outside of the main body case 51.

  A tray insertion hole 4 b into which the disc tray 21 is inserted is formed on the front surface of the case 4. As shown in FIG. 6, when the disc tray 21 is located at the storage position, the tray insertion hole 4b is shielded by the disc tray 21, and when the disc tray 21 is located at the drawer position as shown in FIG. There is a gap between the hole 4b and the disc tray 21.

  Next, the operation of the personal computer main body 50 will be described. As shown in FIG. 6, when the disc tray 21 is located at the storage position, a storage signal is input from the position detection switch 31 to the CPU 54 via the IDE interface, and the CPU 54 can drive the exhaust fan 55 and IDE. The LED 27 is turned off via the interface and the CPU 16. Further, when the storage signal is input, the CPU 54 determines whether or not the temperature detected by the temperature sensor 57 exceeds 35 ° C. When the CPU 54 determines that the detected temperature exceeds 35 ° C., the CPU 54 drives the exhaust fan 55.

  In response to the input of a signal from the open / close switch 26, the CPU 16 drives the tray moving mechanism 22 and moves the disc tray 21 to the drawer position. When the disk tray 21 moves to the drawer position, a drawer signal is input to the CPU 54 via the IDE interface. In response to the input of the extraction signal, the CPU 54 stops the driving of the exhaust fan 55 if it is being driven. Thus, when the disc tray 21 is located at the drawer position, the exhaust fan 55 is driven so that dust outside the main body case 51 does not enter the case 4 through the tray insertion hole 4b. The dust outside the main body case 51 does not enter the inside of the main body case 51 through the connector connection opening formed in 4. By preventing dust from entering the case 4, it is possible to prevent dust from adhering to the pickup head 8 and the objective lens 13.

  Further, the CPU 54 determines whether or not the temperature detected by the temperature sensor 57 exceeds 40 ° C. and 45 ° C. when an extraction signal is input via the IDE interface. If the temperature exceeds 45 ° C., the CPU 54 is likely to break due to a temperature rise. Therefore, it is preferable to warn when the detected temperature approaches the dangerous temperature of 45 ° C. Therefore, if the CPU 54 determines that the detected temperature has exceeded 40 ° C., the CPU 54 issues a warning by blinking the LED 27 via the CPU 16. Furthermore, when the detected temperature exceeds the dangerous temperature of 45 ° C., it is necessary to immediately drive the exhaust fan 55 to lower the temperature inside the main body case 51. Therefore, when the CPU 54 determines that the detected temperature exceeds 45 ° C., the CPU 54 issues a warning by turning on the LED 27 via the IDE interface and the CPU 16, and then drives the tray moving mechanism 22 by the CPU 16 to place the disk tray 21 in the storage position. Move to.

  When the open / close switch 26 is pressed after the disk 3 is mounted on the disk tray 21 located at the drawer position, the CPU 16 drives the tray moving mechanism 22 to move the disk tray 21 to the storage position.

  When the disk tray 21 moves to the storage position, a storage signal is input from the position detection switch 31 to the CPU 54 via the IDE interface. In response to the input of the storage signal, the CPU 54 enables the exhaust fan 55 to be driven. When the CPU 54 determines that the temperature detected by the temperature sensor 57 exceeds 35 ° C., the CPU 54 drives the exhaust fan 55.

  In the first and third embodiments, if the CPUs 16 and 54 determine that the detected temperature exceeds 45 ° C., the LED 27 is turned on and then the disk tray 21 is moved to the storage position. Instead of moving to the storage position, the exhaust fans 17 and 55 may be driven. If it is determined that the detected temperature exceeds 40 ° C., only the warning is first performed by blinking the LED 27. If it is determined that the detected temperature exceeds 40 ° C. (predetermined temperature), the disc tray 21 is removed. You may make it move to a storing position. In addition, the said temperature can be changed suitably.

  Further, in the first and third embodiments, the exhaust fans 17 and 55 are stopped when the disc tray 21 is located at the drawer position, but compared to when the disc tray 21 is located at the retracted position without stopping. Thus, the exhaust fans 17 and 55 may be driven at a low speed.

  Further, in the first and third embodiments, the exhaust fans 17 and 55 are stopped when the disk tray 21 is located at the drawer position and the drawer signal is input to the CPUs 16 and 54. The exhaust fans 17 and 55 may be stopped when they are not in the storage position, that is, when the storage signal is not input to the CPUs 16 and 54. Of course, the exhaust fans 17 and 55 may be driven at a lower speed than when they are located at the storage position. As a result, the withdrawal of the disc tray 21 is hindered in the middle, and the exhaust fans 17 and 55 can be stopped even when the disc tray 21 is located between the storage position and the withdrawal position.

  Further, each of the fans 17 and 55 is composed of an exhaust / intake fan that can be changed between an exhaust state and an intake state, and when the disc tray 21 is located at the storage position, the exhaust / intake fan is brought into an exhaust state, and the disc tray 21 When is located at the drawer position, the exhaust / intake fan may be in an intake state. Of course, when the disk tray 21 is not located at the storage position, the exhaust / intake fan may be in the intake state.

  Moreover, in the said embodiment, although the temperature of CPU16,54 was detected by the temperature sensors 32 and 57, the target object which detects temperature can be changed suitably, for example, the temperature of the pick-up head 8 may be detected. .

  Furthermore, in the above embodiment, the position of the disk tray 21 is detected by the position detection switch 31, but the detection method can be changed as appropriate, and includes, for example, a light emitting unit that emits light and a light receiving unit that receives light. You may detect with an optical sensor. In this case, a reflecting plate that reflects light is attached to the front end portion (lower end portion in FIG. 2) of the side surface of the disc tray 21, and a light sensor is provided on the front end side (lower end side in FIG. 2) inside the case 4. The light emitting unit emits light toward the side surface of the disc tray 21 and the light reflected by the side surface of the disc tray 21 is received by the light receiving unit. When the disc tray 21 is located at the storage position, the light emitted from the light emitting unit is reflected by the reflecting plate and received by the light receiving unit. When the disc tray 21 is moved to the drawing position, the light emitted from the light emitting unit is not reflected by the side surface of the disc tray 21, and the amount of light received by the light receiving unit is reduced. The optical sensor detects the position of the disc tray 21 based on the amount of received light.

  In the first and third embodiments, the present invention is applied to the personal computer main body 50 including the disk device 2 and the disk device 60 in which the disk tray 21 automatically moves. You may implement in an apparatus and a personal computer main body. In this case, if the CPUs 16 and 54 determine that the detected temperature has exceeded 45 ° C., the CPU 27 turns on the LED 27 and then drives the exhaust fans 17 and 55.

  Furthermore, in the said embodiment, it alert | reported that detected temperature exceeded 40 degreeC and 45 degreeC by blinking and lighting of LED27, However, The alerting | reporting method can be changed suitably, for example, you may alert | report with a sound. Moreover, when implementing this invention in the personal computer main body 50 like 3rd Embodiment, you may provide LED in the main body case 51 of the personal computer main body 50, and may alert | report. Further, a message prompting the user to close the disc tray 21 may be displayed on the display screen connected to the personal computer main body 50.
