  A disk device according to an embodiment of the present invention will be described below. FIG. 1 is a block diagram of a disk device according to this embodiment. The basic configuration of the disk device includes a base body 10, a lid body 19, a chassis exterior 23, a disk insertion slot 11, a connector 12, a traverse 30, a printed circuit board 14, a spindle motor 31, a pickup 32, and a driving means 33. The chassis exterior 23 includes a base body 10 and a lid body 19. A disk insertion slot 11 into which a disk is directly inserted is formed on the front surface of the lid 19, and a connector 12 is disposed on the rear surface of the chassis exterior 23. A traverse 30 and a printed circuit board 14 are provided on the base body 10. The traverse 30 holds a spindle motor 31 and a disk, and performs a recording / reproducing operation on the disk by rotationally driving the disk, and also a pickup 32 for releasing the disk from the holding state and a driving means 33 for moving the pickup 32. And holding.

  The disk device further serves as a disk loading control system, a disk insertion detecting means 24 for detecting that a disk has been inserted into the disk device, and a disk for detecting a state in which a disk can be loaded and a loading operation can be performed. Based on the detection information detected by the loading standby state detection means 25 and the disk insertion detection means 24 that the disk has been inserted into the disk device, the disk can be moved into the disk device by driving the loading motor and rotated to the spindle motor 31. A disk loading means 26 to be mounted on the disk, a loading completion detecting means 27 for detecting a state in which the disk loading means 26 has completed the disk loading operation, a disk presence / absence detecting means 28 for detecting the presence / absence of a disk in the disk device, And a mechanical position detector 29 for detecting a mechanical position of the disk loading unit 26.

  The disk insertion detecting means 24 is configured by a switch that is turned off when a disk is inserted and turned on when a disk is not inserted. The disk loading standby state detection means 25 is configured by a switch that is turned on when a disk loading standby state is entered and turned off in a state other than the loading standby state. The loading completion detection means 27 is configured by a switch that is turned on when the loading state of the disk is monitored and the disk is completely loaded, and is turned off otherwise. The disk presence / absence detecting means 28 is composed of a switch which is turned off when there is a disk inside the disk device and turned on when there is no disk. The mechanical position detecting means 29 detects the mechanical position when the mechanism of the disk loading means 26 is moving during the loading operation, and between the standby position and the loading completion position where the mechanism is between the loading completion position and the ejection completion position. The switch is turned on when the switch is on, and is turned off otherwise.

  Further, as a disk discharge control system, a discharge switch 43 for instructing disk discharge, and the disk mounted state on the spindle motor 31 is released by the instruction of the discharge switch 43, and the disk is discharged to the outside of the disk device by driving the loading motor. Disc ejecting means 44 for performing disc ejection, and disc ejecting state detecting means 45 for detecting a state in which the disc has been ejected by the disc ejecting means 44. The disc ejection state detection means 45 is configured by a switch that is turned on when the disc ejection is completed and turned off when the disc ejection is not completed.

  Next, the operation will be described with reference to FIG. FIG. 2 is a flowchart for explaining the initialization operation processing of the disk device according to the embodiment of the present invention. First, when a power-on or initialization operation is requested, basic initialization operation processing in the disk device is performed. In the slot loading type, it is necessary to perform the initialization operation by performing the eject operation once immediately after the power is turned on. The purpose is to return the disk loading mechanism, which may have stopped at an abnormal position, to the normal standby position when there is no disk. In the initialization operation, as shown in FIG. 2, first, the disk presence / absence detecting means 27 determines whether or not a disk exists in the disk device (step 1), and when it is detected that the disk exists in the device. Since the mechanical position is always at the loading completion position, initialization processing in the eject direction is not performed, and spin-up processing is performed to enable recording and reproduction (step 2).

  On the other hand, if there is no disk, the ejection operation is started (step 3), and the disk ejection means 43 is operated to perform the disk ejection operation until the disk ejection state detection means 44 detects the disk ejection state (step 4). When the disk discharge state is detected by the disk discharge operation of the disk discharge means 43, the disk loading means 26 is operated to move to the loading operation (step 5), and the operation is continued until the disk loading standby state detection means 25 detects the disk loading standby state. Thus, the disk loading standby state is set (step 6), and the initialization is completed.

  In addition, since a mechanical movement operation is always performed to return to the standby position when the power is turned on, the loading sound is felt loud when the power is turned on. Therefore, it is preferable to set the drive voltage of the loading motor 60 in the initialization process to be lower than the drive voltage of the normal disk loading process or ejection process. In actual processing, the discharge processing routine may be used as it is, and the drive voltage at the time of discharge may be reduced. During the transition from the power-on to the initialization process, even if the eject switch or the disk detection switch is detected, the event is held without issuing an event and the initialization operation is performed. When the initialization operation is completed, the hold is released.

  Next, the loading operation processing of the disk device will be described with reference to FIG. FIG. 3 is a control flowchart of the loading operation process. When a disk is inserted into the disk insertion slot 14, the disk detection switch as the disk insertion detection means 24 is turned off when a disk is inserted, and is turned on when a disk is not inserted. Thus, the insertion of the disc is detected (step 11). Next, after removing the chattering of the disk, the loading motor 60 of the disk loading means 26 is driven to the loading side to start the loading process (step 12). Note that the insertion of the disc may be detected after the chattering removal (step 11). During the loading process, the loading completion detection means 27 and the disk presence / absence detection means 28 are monitored and driven while controlling the driving operation of the loading motor 60. Further, while monitoring the mechanical position detecting means 29, the position of the loading mechanism at that time is grasped, and the driving voltage of the loading motor 60 is varied for each position of the loading mechanism to perform fine loading control.

  While the loading process is being executed, the disk rotation process (step 13) and the pickup inner circumference feed process (step 14) are performed in parallel with the driving of the loading motor 60. The disk rotation process is performed in order to perform a chucking operation a plurality of times. In other words, there is a risk that chucking may fail in a one-time chucking operation. Therefore, after reaching the position where the loading mechanism performs chucking during the loading process, the loading mechanism is temporarily returned to the ejection direction and driven again in the loading direction. The second chucking operation is performed, and the loading motor 60 is driven so as to perform a plurality of chucking operations by repeating this operation as necessary. At this time, in the disk rotation processing, the disk is rotated by the spindle motor 31 between the first chucking operation and the second chucking operation, and the chucking operation is not repeated repeatedly at the chucking claw position where it is difficult to chuck. Like that. The pickup inner circumference feeding process is a process of moving the pickup in the inner circumference direction of the disk during the loading process in order to shorten the spin-up time of the disk.

The loading completion detection means 27 determines whether or not the loading is completed (step 15). When the loading completion is detected, the loading motor 60 is driven with 0 volts in order to prevent the back electromotive voltage from being generated in the loading motor 60. (Step 16), and the loading motor 60 is rotated in reverse to stop the repulsive force loading operation immediately (step 17). Finally, the mechanism of the disk loading means 26 is locked so that the next disk cannot be inserted and the loading operation is not performed even if a loading request is made again (step 18).
If necessary, after completion of loading in step 16, the loading operation may be continued and further pushed in to prevent the disk from being removed.

Next, disk ejection processing of the disk device will be described with reference to FIG. FIG. 4 is a control flowchart of the disc ejection process. The discharge process is activated either when the discharge switch 43 is pressed or when a discharge command is received. When the eject switch 43 is pressed or a eject command is detected (step 21), the disc is unmounted from the spindle motor 31 (step 22), and the loading motor 60 is driven in the eject direction opposite to the loading direction. Then, discharge processing is performed (step 23).
During the ejection process, the loading motor 60 is driven to move the position of the loading mechanism while monitoring the disk detection means 24, the disk ejection state detection means 45, and the standby position detection means 25. At this time, while monitoring the mechanical position detecting means 29, the position of the loading mechanism at that time is grasped, and the drive voltage of the loading motor 60 is varied for each position of the loading mechanism to perform fine discharge control. The actual discharge process is composed of two operations: movement of the loading mechanism in the discharge direction and return to the standby position. After moving in the eject direction, the loading mechanism is locked, and the mechanism does not move when trying to insert a disc. In order to be able to insert the next disk, it is necessary to move the loading mechanism position again in the loading direction and return to the standby position. If the discharge switch 43 is detected during the discharge process, the current discharge operation is continued without issuing an event. When a new disk ejection instruction is received during the ejection process, the currently executed ejection process is continued.

The disc ejection state detection means 45 determines whether or not the disc ejection has been completed by the disc ejection means 44 (step 24). When it is detected that the disc has been ejected, the disc loading standby state detection means 25 causes the disc loading state detection means 25 to complete the disc loading. It is determined whether or not an operation can be performed (step 25). If it is detected in step 24 that the disc has not been ejected, the ejecting process (step 23) is repeated. If it is determined in step 25 that the disk loading operation can be performed, the loading motor 60 is braked by driving at 0 volts in order to prevent the back electromotive voltage from being generated in the loading motor 60 (step 25). 26) A reverse rotation operation is performed in order to immediately stop the repulsive force loading operation (step 27). Finally, the mechanical position of the loading mechanism is moved to the position where the disk can be inserted so that the next disk can be inserted, and the disk loading standby state is set (step 28).
If it is determined in step 25 that the disc loading operation is not possible, it is determined that the disc has not been ejected, and the ejection process (step 23) is repeated.
It is to be noted that chattering removal is performed as necessary before the disc ejection completion detection unit 45 in step 24 determines the completion of disc ejection or the disc loading standby state detection unit 25 in step 25 determines whether the disc loading operation is possible. Preferably it is done.

  By the way, if the pickup 32 has not moved to the outer periphery during the discharge process, the discharge lever 100 of the disk discharge means 44 may collide with the pickup 32 and damage the pickup 32. Therefore, it is necessary to move the pickup 32 to the outer peripheral position in advance before the discharging process. In the present embodiment, the spin-down process is performed before the discharge process, and the pickup 32 is moved in the outer circumferential direction. Whether or not the outer periphery of the pickup 32 is moved at the time of spin down is determined by whether or not the disk presence / absence detecting unit 28 has detected a disk. When the disk is detected, the outer periphery of the pickup 32 is moved. Absent. Chattering removal is not performed in the disk detection in the disk presence / absence detection means 28 at this time.

  The pickup 32 is moved around the outer periphery by using a DC motor. During the spin-down process, the recording / reproducing laser and focus are turned off, and the spindle motor 31 is turned off. When the spindle motor 31 is turned off, parameters are passed so that the outer periphery of the pickup is moved in parallel with the disk. If the current address can be acquired, the distance from the current position to the outer circumference is obtained, the number of DC motor drive pulses required for the transfer amount corresponding to that distance is calculated, and the pickup 31 is sent to the outer circumference by the number of drive pulses. Move with. At this time, the moving amount of the pickup is monitored by the encoder, and the motor drive is stopped when the encoder output does not change by a predetermined amount or more.

If the current position cannot be obtained, the pickup 32 is once moved to the innermost circumference, and the pickup 31 is moved to the outer circumference by a predetermined number of fixed pulses while monitoring the output of the encoder from the innermost circumference. Even when the pickup 31 is moved to the innermost circumference, the pickup 31 is moved while monitoring the output of the encoder. The reason why the pickup is moved to the innermost circumference and then moved to the outer circumference when the current position cannot be obtained is that when the pickup 32 is directly moved to the outer circumference, the mechanical vibration is more likely to occur than when the pickup 32 is moved to the inner circumference.
It is preferable to move the pickup lens downward in order to prevent the ejection lever from hitting the pickup lens when the disc is ejected.

  The disk apparatus and disk loading method of the present invention are a video / audio recording / reproducing apparatus for recording / reproducing video and audio by CD, DVD, etc., and for data for recording / reproducing data of a computer such as a large computer or personal computer by CD, DVD, etc. The present invention is suitable for application to various recording / reproducing apparatuses using optical disks and magneto-optical disks such as data recording apparatuses, slot loading type analog record cutting apparatuses and record players.
