When the disk cartridge 1 is manually inserted to the innermost part of the cartridge case 52, the pressing force of the disk cartridge 1 causes the electric switch 57 whose tip is inserted through a hole into the innermost part of the cartridge case 52 to connect. The drive force of the motor 55 of the load/eject device 51, which is controlled by a control device to be described later, operates the vertical mechanism 54 of the device 51, thereby moving the cartridge case 52, and thus the disk cartridge 1, to the initial state. The case 5 is vertically lowered from the position and is positioned at a predetermined recording/reproducing position by a positioning device (not shown) provided on the upper surface of the base 61, and the knob 4 of the disc cartridge 1 is Through the window provided in the case 52 and the window 5b of the case 5, the drive knob 13b fixed to the drive shaft of the spindle motor 23a of the rotary drive device 23 fixed to the lower surface of the base 61, The disc 2 is chucked by the attraction force of a chucking magnet (not shown) built into the drive hub 23b, and a so-called loading operation is performed in which the disc 2 is held at a position where it does not come into contact with the inner wall of the case 5.

Then, a disk cartridge attachment detection device (not shown) detects that the disk cartridge 1 is attached to the recording/reproducing position, and the spindle motor 23

As shown in FIG. 9(A), the cartridge case 5
2 is in the initial position, the electromagnet 24 is in a standby position above the cartridge case 52. As shown in FIG. 2B, as the cartridge case 52 is lowered, the electromagnet 24 is moved up and down by the action of the electromagnet lifting device 25 that utilizes the vertical movement of the cartridge case 52. By descending beyond the descending distance, the disc 2 is set at a predetermined recording/erasing position through the window provided in the cartridge case 52 and the window 5a of the case 5, where the clearance with the top surface of the disc 2 is approximately 0.6+on.

At this time, in conjunction with the operation of this cartridge case 52, the electromagnet 2
4 is returned to the standby position. When the user removes the disc cartridge 1, the shutter opening/closing device 22 closes the shutter 6 and the disc cartridge 1 is removed.

The operation of the conventional magneto-optical disk device 50 described above is a summary, but in actual operation,
The recording mode includes a series of operations: erase, write, and verify.

That is, in the conventional magneto-optical disk 2 described above,
Since the magneto-optical film 2b cannot be overwritten, which is possible with magnetic tapes, magnetic disks, etc., prior to the recording operation, the erasing operation of the recording section is first performed, and then the recording operation is performed. will be held. Moreover, this magneto-optical film 2
Since b lacks reliability, a verification operation is performed after this recording operation. That is, this recording section is reproduced (read), the recorded signal and the reproduced signal are compared, and if they match, the process moves to the next operation. In the case of non-coincidence, the recorded signal of this portion is recorded again in a pre-provided alternative area, and then a so-called alternative process is performed in which verification and recording addresses are changed.

Control of the magneto-optical disk device 50 is performed by a control device connected between the disk device 50 and the host computer. This control device includes a disk device 50
8 is housed in a printed wiring board (not shown) disposed within the chassis 60.

FIG. 8 is an explanatory diagram of the operation of an example of the control device of the disk apparatus shown in FIGS. 1 and 9, which will be described later. FIG. 8A shows the operation in the recording mode, and FIG. 8B shows the operation in the playback mode.

As shown in the figure, a conventional control device 70 is connected between a host computer 40 and the magneto-optical disk device 50.

As shown in Figure (A), in the recording mode,
This host computer 40 outputs signals such as a recording command, recording section designation, recording data, etc. to the control device 70. In this control device 70, during a recording operation, an error correction code is added and modulated to this recording data to generate a recording signal. This control device 7
0, the disk device 50 is controlled to rotate the spindle motor 23a, search operation, erase operation,
Instructions for switching between recording operation and verification operation, control of the bias magnetic field by the electromagnet 6, control of the output intensity of the laser diode of the laser recording/reproducing device 26, control of the position of the objective lens 26a in the recording section, etc. are performed. During operation, a recording signal is input.

After the search, erasing, and recording operations are completed by the disk device 50, a reproduction signal for a collation operation is input to the control device 70. In this control device 70, the reproduced signal is demodulated, the above-mentioned verification is performed, and the above-mentioned alternative processing is performed as necessary, and the above-mentioned host computer 40 is provided with the following information:
A report on the completion of the recording order is made.

As shown in FIG. 2B, in the playback mode, the host computer 40 outputs signals such as playback commands and playback section designation to the control device 70. The control device 70 instructs the disk device 50 to control the spindle motor 23a, to switch between the search operation and the reproducing operation, to control the electromagnet 6, to control the laser diode, and to control the objective lens 26a in the reproducing section. Position control, etc. is performed. This disk device 50 performs a search and playback operation, and the control device 70 performs demodulation, error detection, and correction on the playback signal from this device 50. If this playback operation fails, the playback operation is repeated again. A retry operation in which a reproduction operation is performed is performed, and reproduction data is output to the host computer 40.

In this magneto-optical disk device 50, when the user presses the eject button 53 during the above-mentioned recording/reproducing operation, when the above-mentioned eject operation is performed, the disk 2 is ejected.
Since there is a risk that the recorded data will be destroyed, the motor 55 of the load/eject device 51 is controlled by the control device 70 so that the eject operation is not performed until the series of operations being executed is completed. Configured to perform prohibited operations.

(Problems to be Solved by the Invention) In the conventional small magneto-optical disk device 50 having the above configuration, the load/eject device 51 performs the loading operation by the driving force of the motor 55, as described above. Since it is a so-called electric type that performs the eject operation, the motor 55 is large in size, heavy, and consumes power due to its volume, weight, and power consumption (1).

In order to solve the above problem, for example, in a 3.5-inch floppy disk drive device (hereinafter abbreviated as FDD device), loading and ejecting operations are performed using the insertion force of the disk cartridge by the user and the pressing force of the eject button. The so-called manual method is adopted. In this FDD device, since the rotation speed of the disk is low, there is almost no risk of the disk being destroyed even if an eject operation is performed while the disk is rotating. However, in the small magneto-optical disk device 50, , Since the rotational speed force of the disk 2 is large, there is a danger that the disk 2 will be destroyed if this manual load/eject device is adopted.

The present invention has been made with attention to the above points, and has a small size,
It is an object of the present invention to provide an information recording disk device, such as a small magneto-optical disk device, which is lightweight and has low power consumption, and has no risk of destruction of the information recording disk.

In the information self-recording disk device, the host computer, the control device, and the disk device include a load/eject device that operates an eject mechanism to eject at least an information recording disk cartridge. If there is a need for an eject prohibition operation in which the ejection operation of the disk cartridge is not performed until the series of operations being executed in this disk device is completed at least in one place, the pressing force of the eject button should be adjusted to the This configuration includes a load/eject device having an eject prohibition mechanism that does not transmit information to the eject mechanism.

Further, in the information recording disk device of the present invention, in the information recording disk device described above, the eject prohibition mechanism includes an electric-mechanical conversion element that allows and prevents entry of the eject button.

Further, in the information recording disk device of the present invention, the rotation of the information recording disk is performed based on an open/close signal of an electric switch that is activated in conjunction with depression of an automatically returning eject button arranged on the front panel. The spindle motor is configured to stop rotation of a driving spindle motor and control energization of the electric machine conversion element.

Further, in the information recording disk device of the present invention, the rotation stop of the spindle motor and the energization of the electric machine conversion element are controlled based on an opening/closing signal by a user's operation of an eject request electric switch in the information recording disk device. It is structured like this.

Further, the information recording disk device of the present invention is configured such that, in the information recording disk device, after the rotational speed of the spindle motor falls below a predetermined value, the electrical machine conversion element is switched from the blocking side to the allowing side by energizing the electric machine conversion element. This is what I did.

(Embodiment) The information recording disk device of the present invention is of the above-mentioned manual type, and in addition, there is a need for the eject prohibition operation in at least one of the host computer, the control device, and the disk device. The above object is achieved by providing a load/eject device having an eject prohibition mechanism that does not transmit the pressing force of the eject button to the eject mechanism.

As shown in FIG. 1, a small magneto-optical disk device 10 according to an embodiment of the present invention is used with the above-described disk cartridge 1 installed, and includes a load/eject device 11, a chassis 20, a base 21, and a shutter opening/closing device. It is comprised of a device 22, the rotation drive device 23, the electromagnet 24, the electromagnet vertical device 25, the laser recording/reproducing device 26, and the like.

This disk device 10 has a load eject device 11, a chassis 20, and a base 21.
The control device 30 that controls this disk device 10 is different from the conventional control device 70 described above only in the portions related to the load/eject device 11. Therefore, Figures 7 and 8
9 and 9, descriptions of the same parts as in the conventional example described above will be omitted.

As shown in FIG. 1, FIG. 2, and FIG. 3, the load/eject device 11 that attaches and detaches the disk cartridge 1 described above includes a cartridge/body case 12, an eject button 13 made of resin, an up/down mechanism 14, and a lock. Mechanism 15, eject request electric switch 16, eject prohibition mechanism 1

This vertical mechanism 14 is integrally moved in the longitudinal direction of the button 13 by the pressing force of a total of four rollers 12b1 eject buttons 13, two of which are installed facing outward on both sides of the cartridge case 12. The hook portion 14c protruding through the hole 21a on the lower surface side of the base 21 is pressed by the tip of the formed arm portion 13a, so that the horizontal portion 14b extends from the upper surface of the base 21 in the depth direction of the disk device 10. The eject lever 14a1 that slides horizontally is composed of a spring 14f and the like that urges the eject lever 14a toward the front panel 2Oa. Further, the locking mechanism 15 is connected to a roller pin 14g that is set upright at the right rear end of the top surface of the horizontal portion 14b of the eject lever 14a, and a shaft 21 that is set upright on the top surface of the base 21.
A lock lever 15 disposed between the cartridge case] 2 and the base 21, whose central portion is pivoted by b and rotates horizontally to lock and release the roller pin 14g.
a1 A spring 15d that biases the lock lever 15a in the clockwise rotation direction in FIG.
It is composed of etc.

When the cartridge case 12 is in the initial position, the roller pin 14g is formed at the opposite end of the sensor pin 15e with respect to the axial center point of the lock lever 15a, as shown in FIG. 2(A). It is engaged with the groove portion 15b that has been opened, and is in a locked state. In this state, as shown in FIG.
When e is pressed to the innermost part of the case 12 by the pressing force caused by the insertion of the disk cartridge 1 described above, the lock lever 15a rotates in the counterclockwise rotation direction in FIG. and groove portion 15b
The locked state caused by the engagement with is released.

By releasing this locked state, the eject lever 14
a slides toward the front panel 2Oa side by the biasing force of the spring 14f, and as a result of this sliding, the roller 12b moves downward along the diagonally vertical guide groove 14e formed on both side plate portions 14d of the eject lever 148. By being pushed down by
2 reaches the recording/reproducing position, the loading operation is completed.

Further, when the eject prohibition mechanism 17 is in the eject permission state, which will be described later, the eject lever 14a slides toward the back of the disk device 10 due to the pressing force of the eject button 13, and the roller pin 14g is moved to the lock lever. It moves along the tapered portion 15C formed between the tip portion 15b and the tip portion and engages with the groove portion 15b, thereby entering a locked state. At this time, as the eject lever 14a slides, the guide groove 14e
The roller 12b is pushed upward along the cartridge case 12, and the cartridge case 12 reaches the initial position, thereby performing the ejecting operation.

The eject button 13 is automatically returned to the standby state before being pressed by the urging force of the spring 13b that urges the tip of the arm portion 13a toward the front panel 2Oa at the same time when the user ends the pressing.

The aforementioned eject prohibition operation in the load/eject device 11 is executed by the eject request electric switch 16, the eject M stop mechanism 17, the control device 30, etc., as shown in FIG.

As shown in the same figure (A), this ejection inhibiting mechanism 17
consists of a fixed part 17b fixed to the lower surface of the base 21, and a movable part 17c that protrudes from the fixed part 17b by the biasing force of a built-in spring (not shown) when the fixed part 17b is not energized. The solenoid plunger 17a1 is fixed to the tip of the movable portion 17c, and is arranged between the tip of the arm portion 13a of the eject button 13 in the above-mentioned standby state and the hook portion 14c in a position corresponding to the above-mentioned recording/reproducing state. stopped/<-1
7d, the arm portion 13a1 is arranged so as to contact the hook portion 14c side surface of this strut tube <-17d when not energized.
The hook portion 14C1 is composed of a reinforcing portion (not shown) and the like that is erected on the lower surface of the base 21 so as not to hinder the operation of the manual release mechanism 18, which will be described later.

When the eject button 13 is in the standby state, the eject request electric switch 16 whose tip is in contact with the side surface of the arm portion 13a by -1 is in the off state;
In this off state, the solenoid plunger 17a
is in a de-energized state.

When the solenoid plunger 17a is in the de-energized state, the stop lever 17d prevents the hook portion 14c from being suppressed by the tip of the arm portion 13a, and the ejection inhibiting mechanism 17 is in the eject inhibiting state. . In this eject inhibit 11- state, the stop lever 17d is reinforced by the reinforcing portion against the pressing force of the arm portion 13a.

As shown in FIG. 2B, when the eject button 13 is pressed by the user, the eject request electric switch 16 is first pressed by the tapered portion 13b formed on the side surface of the arm portion 13a. is turned on by being pressed, and an on signal representing this on state is supplied to the control device 30. This control device 30 causes the host computer 40,
If there is no need for the eject prohibition operation in the control device 30 and the disk device 10, the movable portion 17c is attracted by passing an excitation current to the fixed portion 17b of the solenoid plunger 17a, and the stop lever 17d is is moved to the retracted position, and the ejection prohibition mechanism 17 enters the ejection permission state.

In this eject permission state, the above-described eject operation is performed by the tip of the arm portion 13a of the eject button 13 pressing the hook portion 14c of the eject lever 14a. Control device 30 and disk device 10
If there is a need for the ejection inhibiting operation in at least one of the locations, the solenoid plunger 17a
maintains a non-energized state, and the ejection inhibiting mechanism 17 maintains the eject inhibiting state.

Next, details of the eject operation in the disk device 10 under the control of the control device 30 will be explained with reference to FIG.

FIG. 4 is a flowchart of the eject operation in the disk device of FIG. 1.

As shown in the figure, the eject button 1 by the user
3, the eject request electric switch 16 is activated.
When turned on, the control device 30 determines whether there is a need for the eject prohibition operation in at least one of the host computer 40, the control device 30, and the disk device 10, and determines whether there is a need for the eject prohibition operation. In this case, the ejecting operation is not performed due to the function of the ejecting inhibiting mechanism 17 described above. If there is no such need, the operation of the laser recording/reproducing device 26 and the spindle motor 23a in the disk device 10 is stopped under the control of the control device 30, and a rotation detection device (not shown) incorporated for controlling the motor 23a is used. Based on the detection signal, it is detected whether the rotation speed of this motor 23a has become below a predetermined value. When the rotational speed of the spindle motor 23a reaches a predetermined value that does not hinder the ejecting operation, the ejectable display indicator 20d installed on the front panel 20a turns on, and
The solenoid plunger 17a is turned on, and the ejection prohibition mechanism 17 is placed in the ejection permission state.

Here, when the aforementioned eject operation is performed and it is confirmed by the disk cartridge mounting detection device that the disk cartridge 1 is not at the recording/reproducing position, the solenoid plunger 17a is turned off and the indicator 20d is turned off. is turned off, and the ejection prohibition mechanism 17 is placed in the above-mentioned injection prohibition state.

Also, if the disk cartridge 1 is in the recording/reproducing position for some reason, the solenoid plunger 17a
In order to reduce power consumption due to the excitation current flowing through the solenoid plunger 17a, the solenoid plunger 17a is turned off after a predetermined period of time, and the ejectable indicator 20d is turned off.

In the above-described embodiment of the present invention, the load/eject device 11 stops the spindle motor 2 by a brake device (not shown) after the eject request electric switch 16 is connected in conjunction with depression of the eject button 13.
This is based on the assumption that the rotation speed of the motor 23a reaches a predetermined value or less in a short time, but if it takes 7 hours to reduce the rotation speed of the motor 23a, the following configuration can be used. .

For example, the first press of the eject button 13 by the user only connects the eject request electric switch 16, and after confirming that the rotation speed of the motor 23a has reached a predetermined value or less and that the indicator 20d is lit, the eject button is pressed. Due to the second suppression by 13 users,
It is also possible to adopt a configuration in which the ejecting operation described above is completed by operating the vertical mechanism 14.

Further, this eject request electric switch 16 is disposed on the front panel 20a, and when the user connects this switch 16, the rotation speed of the motor 23a decreases and the indicator 20d lights up, and then when the eject button 13 is pressed by the user, the above-mentioned It is also possible to have a configuration in which the ejection operation of the ejecting device is completed. In this case, if the user does not press the eject button 13 for some reason after connecting the switch 16, as explained in FIG.
Since the excitation current of the solenoid plunger 17a is turned off after a predetermined time has elapsed, power consumption can be reduced.

In addition, if a power failure occurs while the disk cartridge 1 is at the recording/reproducing position, the solenoid plunger 1
7a cannot be operated, the ejection operation is enabled by the operation of the manual release mechanism 18.

As shown in FIG. 3(C), this manual release mechanism 18
a release lever 18a made of a thin plate, disposed parallel to the lower surface of the base 21, one end in contact with the back surface of the front panel 20a, and the other end facing the tip of the stop lever 17d in the ejection prohibited state; This lever 1
A shaft 18b1 is installed on the lower surface of the base 21 and rotatably attaches the central part of the lever 18a to the shaft 18b1 in the same figure (C).
, it is composed of a spring 18c that biases in the clockwise rotation direction.

During a power outage, the user can open the hole 20 in the front panel 20a.
When one end of the release lever 18a is pressed by the tip of the rod-shaped object 19 through e, the lever 18a rotates in the counterclockwise direction, and the other end of the lever 18a presses the tip of the stop lever 17d. As a result, the ejection prohibition mechanism 17 enters the ejection permission state described above. In this state, the eject button 1 is pressed by the user.
By pressing 3, the eject operation described above is performed and the disk cartridge 1 is taken out.

The height of the release lever 13a from the lower surface of the base 21 is higher than the arm portion 13a and the hook portion 14c, so that it does not come into contact with both during rotation.

The compact magneto-optical disk device 10 according to an embodiment of the present invention having the above-described configuration is similar to the disk device 5 of the conventional example described above.
0, the load/eject device 11 is of the manual type, so it is smaller, lighter, and consumes less power. The ejection inhibiting mechanism 17 is also provided, and under the control of the control device 30, the host computer 40,
If there is a need for the eject prohibition operation in at least one of the control device 30 and the disk device 10, the ejection operation is not performed, so there is no risk of destruction of the disk 2 and recorded data. Further, since the eject request electric switch 16 stops the rotation of the spindle motor 23a and the eject operation is performed after the rotation speed of the motor 23a reaches a predetermined value or less, there is no risk of destruction of the disk 2. . Further, after the rotational speed of the motor 23a decreases, if the disk cartridge mounting detection device detects that the disk cartridge 1 is at the recording/reproducing position, the excitation current of the solenoid plunger 17a is changed after a predetermined period of time has elapsed. Since it is turned off later, power consumption can be reduced.

Furthermore, in the event of a power outage, the manual release mechanism 18 enables the eject operation, which is convenient when taking out the disk cartridge 1 in the event of a power outage.

The loading/ejecting device 11 in the disk drive 10 according to the embodiment of the present invention described above is an example in which the disk cartridge 1 is lowered and raised. It is also possible to have a configuration that performs an eject operation.

(Effects of the Invention) The information recording disk device of the present invention configured as described above is of a manual type and is equipped with a load/eject device having the ejection inhibiting mechanism, so that it is small and lightweight. , low power consumption is achieved, and
There is no risk of destruction of the information recording disk, and the usability and reliability of this disk device are improved, making it suitable for portable use. Further, since the ejection prohibition operation is electrically controlled by the control device using the electric switch and the electric machine conversion element, the ejection prohibition operation is reliable and power consumption can be reduced. Become. Further, since the ejection inhibiting operation is performed after the rotational speed of the spindle motor falls below a predetermined value, there is no risk of destruction of the disk, and the reliability of the disk device is improved.
