[0047]
Further, when the first protrusion 38 and the second protrusion 40 separate from the first actuator 54 and the second actuator 58 and approach the first recess 37 and the second recess 39, there is no contact (pushed). The actuator protrudes, and the conduction of the first detection switch 53 and the second detection switch 57 is released.
[0048]
In addition, the first detection switch 53 and the second detection switch 57 move the recording medium 130 in which the third gear 34 has rotated counterclockwise and the recording medium pushing-out pin 36 has been inserted into the second insertion slot 3 to the second position. When the second detection switch 57 is ejected by hand to the extent that it can be removed by hand, the second actuator 58 of the second detection switch 57 is in the second recess 39 of the third gear 34, and the first actuator 54 of the first detection switch 53 is just It is also arranged so as to be pushed into the second projection 40 of the third gear 34.

This means that the recording medium 130 on either the first insertion port side or the second insertion port side can be discharged, or the recording medium on either the first insertion port side or the second insertion port side. This means that the discharge of 130 has been completed.
[0050]
When only the second detection switch 57 is turned on, it means that the recording medium 130 inserted into the first insertion slot 2 has been ejected from the first insertion slot 2 to the extent that the recording medium 130 can be taken out by hand, and only the first detection switch 53 is set. When the conduction occurs, the recording medium 130 inserted into the second insertion slot 3 has been ejected to the extent that the recording medium 130 can be manually removed from the second insertion slot 3, so that the control unit 110 rotates the driving motor 20 as described later. Then, the recording medium push-out pin 36 can be returned to the original initial position by reverse rotation.
[0051]
Next, as shown in FIG. 2, the connector section 70 exchanges information with the first substrate 71 disposed behind the first insertion port side of the chassis bottom surface 11 and the recording medium 130 mounted on the first substrate 71. Exchanges information with a first I / F (interface) connector head 72, a second substrate 73 disposed behind the second insertion port side of the chassis bottom surface 11, and a recording medium 130 mounted on the second substrate 73.

What is provided between the first lock lever 82 and the second lock lever 86 is not limited to a tension coil spring, but can pull the first lock lever 82 and the second lock lever 86 to each other. Is fine.
[0053]
Here, as shown in FIG. 8 described later, the cam body 81 is formed symmetrically with respect to the line connecting the shaft 35 and the recording medium pushing pin 36 formed on the third gear 34, and the recording medium pushing is formed. When the recording pin 36 reaches the initial position, the locking portions of the first lock lever 82 and the second lock lever 86 can lock the recording medium 130, and the recording medium pushing pin 36 pushes the recording medium 130 out. Before the start, the shape of the extruded recording medium side of the first lock lever 82 or the second lock lever 86 on the recording medium side can be unlocked by the locking portion, for example, the long axis is the shaft 35 and the recording medium pushing pin 36. Are formed in a substantially elliptical shape so as to coincide with the direction of the line connecting.
[0054]
As shown in FIG. 5, each of the first locking portion 83 and the second locking portion 87 has a substantially inverted L-shaped hooking portion facing the chassis bottom surface 11, and each of the hooking portions has a first hooking portion. A first tapered portion 84 and a second tapered portion 88 are formed on the surface in the 2-gear side direction. As a result, the hooked portion of the locking portion is smoothly hooked on the recording medium 130, and thereafter the recording medium 130 is firmly fixed by the tension of the extension coil spring 90.
[0055]
Next, the control unit 110 will be described.
[0056]
As shown in FIG. 6, a CPU (Central Processing Unit) 111 that performs calculations and controls, records information and the like as needed, and controls the recording / reproducing apparatus 1 such as the slot 4 more smoothly. A RAM (Random Access Memory) 112, a ROM (Read Only Memory) 113, a data storage unit 114, and a software storage unit 115 for storing various software are provided.
[0057]
The control unit 110 is connected to a power supply unit 122 that outputs a predetermined current to the drive motor 20 based on information from the control unit 110.
[0058]
Here, the data storage unit 114 stores, for example, data necessary before the ejection of the hard disk 131 under the control of the CPU 111.
[0059]
The software storage unit 115 includes a power switch lock mechanism 116, a discharge recording medium determination mechanism 117, a discharge possibility determination mechanism 118, a discharge pre-processing mechanism 119, a detection switch information mechanism 120, a drive motor control mechanism 121, and the like. .
[0060]
Here, the power switch lock mechanism 116 is for preventing the power switch from being operated so that the power is not cut off during the ejection, and the ejection recording medium determination mechanism 117 uses the first ejection button 102 and the second ejection button 103 for the ejection. It is to determine which one of the first insertion slot 2 or the second insertion slot 3 is ejected from the hard disk 131 which is desired to be ejected, depending on which one is pressed. The determined information is output to the discharge possibility determination mechanism 118, the discharge pre-processing mechanism 119, and the drive motor control mechanism 121 under the control of the CPU 111.
[0061]
Further, the discharge possibility determination mechanism 118 determines whether or not the hard disk 131 to be discharged exists, and whether the hard disk 131 to be discharged cannot be discharged due to recording or playback or the like. The information is output to the processing mechanism 119 and the drive motor control mechanism 121.
[0062]
Further, the ejection pre-processing mechanism 119 stores, for example, data of the hard disk 131 to be ejected in the data storage unit 114 or the like as necessary. The detection switch information mechanism 120 includes a first detection switch 53 and a second detection switch. It monitors the ON / OFF of the switch 57 and outputs the information to the controllable drive motor control mechanism 121 of the CPU 111.
[0063]
Further, the drive motor control mechanism 121 controls the rotation direction, the rotation start, the pause, and the like of the drive motor based on the information from the discharge recording medium determination mechanism 117, the discharge possibility determination mechanism 118, and the detection switch information mechanism 120 under the control of the CPU 111. These commands are used to control reverse rotation and rotation stop. These commands are input to the power supply unit 122, a predetermined current is output from the power supply unit 122 to the drive motor 20, and the drive motor 20 is driven. It is.
[0064]
Specifically, for example, when it is desired to eject the hard disk 131 inserted into the first insertion slot 2 and the worm gear 31 of the gear unit 30 is a left-hand thread, the drive motor control mechanism 121 When the motor shaft 21 of the drive motor 20 is instructed to supply a current that rotates clockwise as viewed from the shaft side, and when only the second detection switch 57 is electrically turned on, the drive motor The control mechanism 121 instructs the power supply unit 122 to temporarily stop the supply of the current to the driving motor 20 and then supply the current to the power supply unit 122 to rotate in the reverse direction.
[0065]
Further, when both the first detection switch 53 and the second detection switch 57 are electrically turned on, the drive motor control mechanism 121 stops supplying the power supply unit 122 with the current to the drive motor 20. Order.
[0066]
When the ejection of the hard disk 131 inserted in the second insertion slot 3 is desired, the drive motor control mechanism 121 causes the power supply unit 122 to rotate the motor shaft 21 of the drive motor 20 counterclockwise as viewed from the shaft side. When only the first detection switch 53 is electrically turned on, the driving motor control mechanism 121 supplies the power supply unit 122 with the current supplied to the driving motor 20. Is temporarily stopped, and then the current is supplied to the power supply unit 122 so as to rotate in the reverse direction. The following is the same as the case where the ejection of the hard disk 131 inserted into the first insertion slot 2 is desired.
[0067]
Thus, when the recording medium pushing pin 36 is ejected from the first insertion port 2 by the third gear even if the number of the drive motors 20 is one, the drive motor 20 is rotated clockwise. The hard disk 131 can be pushed out by moving the recording medium pushing pin 36 clockwise to eject the hard disk 131. When the hard disk 131 is ejected from the second insertion port 3, the drive motor 20 is rotated counterclockwise to The push-out pin 36 can be moved counterclockwise to push out the hard disk 131, so that the number of components and cost of the recording / reproducing apparatus 1 can be reduced.
[0068]

For example, a case will be described in which the hard disk 131 inserted into the first insertion slot 2 is ejected as shown in FIGS.
[0072]
First, when the first eject button 102 of the operation panel 101 of the recording / reproducing apparatus 1 is pressed as shown in FIG. 1, the information is input to the control unit 110 as shown in FIG. 6, and the power is not turned off during the discharging operation. Thus, the power switch is locked by the controlled power switch lock mechanism 116 of the CPU 111 so that the power switch does not work (ST101).
[0073]
Next, the CPU 111 outputs information from the first eject button 102 to the ejection recording medium determination mechanism 117, and the ejection recording medium determination mechanism 117 determines whether one of the first ejection button 102 and the second ejection button 103 has been pressed. Then, the first insertion port 2 which is the insertion port for performing the discharging operation is determined (ST102). The selection information is input to the discharge possibility determination mechanism 118 under the control of the CPU 111.
[0074]
Further, the discharge possibility determination mechanism 118 to which the determination information is input detects and determines whether the hard disk 131 is inserted into the first insertion opening 2 by using, for example, a detection switch provided on the partition plate 14 (ST103). . Thereby, when it is determined that the hard disk 131 is not inserted into the first insertion slot 2, there is no hard disk 131 to be ejected, so that the state returns to the state before ST101, and useless operation can be prevented.
[0075]
Next, when the ejection possibility determination mechanism 118 determines that the hard disk 131 is inserted into the first insertion slot 2, the information is input to the controlled ejection pre-processing mechanism 119 of the CPU 111, and the pre-ejection processing is performed. The mechanism 119 performs processing such as storage of information and files related to the hard disk 131 inserted into the first insertion slot 2 (ST104). As a result, it is possible to prevent the data and the like of the hard disk 131 from being damaged by the discharging operation.
[0076]
Further, under the control of the CPU 111, when pre-discharge processing such as storage of a file by the pre-discharge processing mechanism 119 is completed, the information is input to the discharge possibility determination mechanism 118, and the discharge possibility determination mechanism 118 determines that the discharge prohibition factor that prevents other discharges has occurred. It is determined whether or not there is (ST105).
[0077]
For example, when recording or playback is being performed by the hard disk 131 inserted into the first insertion slot 2, the information is input to the discharge possibility determination mechanism 118 under the control of the CPU 111, and the information is input to the discharge possibility determination mechanism 118. It is determined that the ejection is prohibited, and the operation returns to the operation before ST104 in order to restrict the ejection operation of the hard disk 131 inserted into the first insertion slot 2. As a result, the discharging operation can be started when it is most convenient for the recording / reproducing apparatus 1.
[0078]
Next, when the discharge possibility determination mechanism 118 determines that there is no discharge prohibition factor that prevents the discharge of the hard disk 131, the information is input to the controlled detection switch information mechanism 120 of the CPU 111, and the first detection switch 53 and the It is determined whether both of the two detection switches 57 are electrically conducting (electrically on) (ST106).
[0079]
Accordingly, for example, if it is determined that both the first detection switch 53 and the second detection switch 57 are electrically ON, the first actuator 54 is formed on the third gear 34 as shown in FIGS. The second actuator 58 of the second detection switch 57 is similarly pressed and pushed by the second projection 40 formed on the third gear 34. It will be.
[0080]
Therefore, the first protrusion 38 formed on the third gear 34 at the first detection switch 53 and the second protrusion 40 formed on the third gear 34 at the second detection switch 57 come. The pin 36 for ejecting the recording medium is located at the rear end of the partition plate 14, which is the initial position, and the third gear is rotated on either side of the first insertion port 2 and the second insertion port 3. It becomes possible.
[0081]
On the other hand, when it is not determined that both the first detection switch 53 and the second detection switch 57 are electrically ON, for example, both the first detection switch 53 and the second detection switch 57 are not electrically conductive ( When it is determined that the switch is in the “electrically off” state, both the first detection switch 53 and the second detection switch 57 are in an incomplete position, for example, as shown in FIG. 11 or FIG. In the first recess 37 of the third gear 34, the second detection switch 57 is at a position where the third gear 34 is partially cut linearly.
[0082]
In such a case, it is possible that the hard disk 131 in the first insertion slot 2 has already been ejected or some abnormal state has occurred. Will be returned to.
[0083]
Also, for example, when it is determined that only the second detection switch 57 is electrically ON, the first detection switch 53 is connected to the first recess 37 of the third gear 34 as shown in FIG. 12 or FIG. The detection switch 57 is located at the first protrusion 38 of the third gear 34, and the hard disk 131 in the first insertion slot 2 has already been ejected and the third gear 34 is being rotated in the reverse direction, or somehow. Since it is possible that an abnormal state has occurred, the operation returns to the operation before ST101 without instructing the start of the discharging operation.
[0084]
Next, it is determined that both the first detection switch 53 and the second detection switch 57 are electrically turned on, and the information and the first insertion port, which is an insertion port to be discharged by the discharge recording medium determination mechanism 117, are determined. When the determination information to select 2 is input to the controllable drive motor control mechanism 121 of the CPU 111, the drive motor control mechanism 121 determines that the worm gear 31 of the gear unit 30 has a left-hand thread, for example. Under the control of the CPU 111, the CPU 122 is instructed to supply a current to the drive motor 20 so that the motor shaft 21 of the drive motor 20 rotates clockwise (direction C shown in FIG. 9) when viewed from the shaft side. The power supply unit 122 supplies a necessary current to the drive motor 20 based on the information, and the drive motor 20 rotates the motor shaft 21 clockwise as viewed from the shaft side (ST1). 7).
[0085]
As a result, the third gear 34 starts to rotate clockwise (direction A in FIG. 9) as shown in FIG. 9, and the cam body 81 also starts to rotate at the same time. The first lock lever 82 pressed and closed by 90 is opened in the direction B in FIG. 9 around the first lock lever fulcrum shaft 85, and the first locking portion provided on the first lock lever 82 accordingly. The hooked portion of 83 starts to move in the locking groove left 140 of the locking portion left 137 of the hard disk case 133 described later.
[0086]
Next, when the third gear 34 further rotates as shown in FIGS. 10 and 15 (in the direction A in FIG. 10 and the direction D in FIG. 15), the first lock lever 82 (the first locking portion 83) is moved. Further, as the cam body 81 rotates, it is further opened in the direction B in FIG. 10 (the direction E in FIG. 15), and the portion where the first locking portion 83 provided on the first lock lever 82 is caught is formed by the hard disk case 133. The first locking portion 83 that is disengaged from the locking groove left 140 of the locking portion left 137 and is provided on the first lock lever 82 for a predetermined period of time releases the lock without returning to the original position due to the shape of the cam body 81. Keep the position of.
[0087]
At this time, the first detection switch 53 and the second detection switch 57 are not pushed by the first actuator 54 and the second actuator 58, and are electrically off. Further, the detection switch information mechanism 120 can determine that the ejection operation of the hard disk 131 of the first insertion slot 2 is being performed by inputting the electrically turned off information under the control of the CPU 111. Become.
[0088]
Further, when the third gear 34 rotates as shown in FIGS. 11 and 16 (in the direction A in FIG. 11 and the direction D in FIG. 16), the recording medium pushing pin 36 of the third gear 34 is moved to the hard disk case 133. By pressing the vertical wall 138 as it is, the ejection of the hard disk 131 starts. At this time, the first locking portion 83 provided on the first lock lever 82 keeps the unlocked position, so that the hard disk 131 is smoothly discharged.
[0089]
Next, when the third gear 34 further rotates, the first protrusion 38 of the third gear 34 pushes the second actuator 58 of the second detection switch 57 from the right as shown in FIGS. While the detection switch 57 is electrically turned on, the first detection switch 53 is in the first recess portion 37, and there is nothing to push the first actuator 54, so that the first switch 53 is electrically turned off. Based on the information, the detection switch information mechanism 120 determines that only the second detection switch 57 has been electrically turned on (ST108).
[0090]
Further, only the second detection switch 57 is not electrically turned on. For example, when it is determined that both the first detection switch 53 and the second detection switch 57 are electrically turned on, the initial position is still not determined due to some abnormality. Therefore, the operation returns to the operation before ST107.
[0091]
Next, when the detection switch information mechanism 120 determines that only the second detection switch 57 is electrically ON, the information that only the second detection switch 57 is electrically ON is controlled by the CPU 111. The driving motor control mechanism 121 is input from the detection switch information mechanism 120 to the driving motor control mechanism 121, and the driving motor control mechanism 121 outputs a command to the power supply unit 122 to temporarily stop the current supply to the driving motor 20. The unit 122 temporarily stops the current supply to the drive motor 20, and the drive motor 20 temporarily stops (ST109). At this time, the hard disk 131 is in a state where it can be manually removed from the first insertion slot 2, and the ejection of the hard disk 131 itself is completed.
[0092]
Next, the drive motor control mechanism 121 reverses the rotation of the drive motor 20 and applies a predetermined current to the power supply unit 122 so that the third gear 34 rotates in the F direction in FIG. 13 and the H direction in FIG. The power supply unit 122 supplies a current to the driving motor 20 so that the driving motor 20 rotates in the reverse direction (ST110).
[0093]
Further, the third gear 34 rotates in the direction F of FIG. 13 and the direction H of FIG. 18, and the first actuator 54 of the first detection switch 53 is moved by the first protrusion 38 of the third gear 34 as shown in FIG. When the second actuator 58 of the second detection switch 57 is pressed by the second protrusion 40 of the third gear 34 to be electrically turned on, the detection switch information mechanism 120 to which the information has been input is detected. It is determined whether both of the switches are electrically on (ST111). If it is determined that both the first detection switch 53 and the second detection switch 57 are electrically on, the determination information is transmitted to the CPU 111. Is input from the detection switch information mechanism 120 to the drive motor control mechanism 121, and the drive motor control mechanism 121 stops the current supply to the drive motor 20 to the power supply unit 122. To make it outputs an instruction, whereby the power supply unit 122 stops the current supply to the drive motor 20, drive motor 20 stops its rotation (ST 112).
[0094]
If the detection switch information mechanism 120 does not determine that both of the detection switches are electrically ON, for example, some abnormality has occurred and the recording medium pushing pin 36 of the third gear 34 is still in the initial position. Since there may be a case where it has not returned, the operation returns to the operation before ST110.
[0095]
Next, when the power supply unit 122 stops supplying current to the drive motor 20 according to a command from the drive motor control mechanism 121 and the information is input to the power switch lock mechanism 116, the power switch lock mechanism 116 The lock of the power switch is released so that the power switch under the control of (1) works (ST113). Thus, the recording / reproducing apparatus 1 ends a series of discharging operations of the hard disk 131.
[0096]
In addition, the ejection of the hard disk 131 in the first insertion slot 2 has been described. However, even when the second eject button 103 is pressed, the ejection can be performed according to the present embodiment as in the case of the first eject button 102. When the second eject button 103 is pressed, the hard disk 131 in the second insertion slot 3 is ejected, the direction in which the drive motor 20 first starts rotating is counterclockwise, and the third gear 34 The direction of first rotation is also counterclockwise, and the second lock lever 86 moves by the action of the shape of the cam body 81. The first stop of the drive motor 20 that has started to rotate counterclockwise is performed by the first lock lever 86. This is when only the detection switch 53 is pressed by the second protrusion 40 and is electrically turned on.
[0097]
Further, if the second eject button 103 is pressed during the ejection operation of the hard disk 131 of the first insertion slot 2, the information is temporarily stored under the control of the CPU 111, for example, and the ejection operation of the hard disk 131 of the first insertion slot 2 is completed. The ejection operation of the hard disk 131 from the second insertion slot 3 will be started later.
[0098]
As described above, according to the present embodiment, the rotation of one drive motor 20 causes the rotation of the first motor 2 on the circumference around the shaft 35 formed between the first insertion port 2 and the second insertion port 3. When ejecting the hard disk 131 in the first insertion slot 2, the recording medium pushing pin 36 can be moved clockwise so that the hard disk 131 in the second insertion slot 3 can be ejected in a counterclockwise direction. With this arrangement, even if only one drive motor 20 is used, both of the hard disks 131 inserted into the two insertion ports can be ejected, and the number of components and cost of the recording / reproducing apparatus 1 can be reduced. Can be.
[0099]
Further, the first detection switch 53 and the second detection switch 57 are arranged on the outer circumference of the circumference on which the recording medium pushing pin 36 moves, and the detection signals are controlled by both the first detection switch 53 and the second detection switch 57. When the rotation of the drive motor 20 is started or stopped when the detection signal is input to the control unit 110 and a detection signal is input to the control unit 110 from only one of the first detection switch 53 and the second detection switch 57, Since the control unit 110 for stopping the rotation of the drive motor 20 and thereafter rotating the drive motor 20 in the reverse direction is provided, the discharge of the two hard disks 131 can be accurately controlled even with one drive motor 20.
[0100]
Further, when the ejection of the hard disk 131 in the first insertion slot 2 is completed, information indicating that the hard disk 131 in the second insertion slot 3 is electrically turned on is output only from the second detection switch 57. At the end of ejection, only the first detection switch 53 outputs a detection signal indicating that the hard disk 131 in the first insertion slot 2 is electrically turned on. Can be distinguished from the end of the ejection of the hard disk 131, so that the drive motor 20 can be returned to the original position by rotating it in the reverse direction, and the desired hard disk 131 can be easily and reliably provided by one drive motor 20. Can be discharged.
[0101]
The rotation of the drive motor 20 causes the cam main body 81 to rotate about the shaft 35, and the first lock that locks the hard disk 131 when the hard disk 131 in the first insertion opening 2 is ejected by the rotation. A first lock lever 82 that opens and closes the portion 83 is provided, and when the hard disk 131 in the second insertion slot 3 is ejected, a center line formed between the first insertion slot 2 and the second insertion slot 3 is set to a center line. Since the second lock lever 86 is provided at an equal distance from the first lock lever 82 to open and close the second locking portion 87 that locks the hard disk 131, one drive motor 20 provides The lock of the hard disk 131 to be ejected among the two hard disks 131 can be released only when the hard disk 131 is ejected. As a result, the hard disk 131 can be securely locked at the time of recording and reproduction, and only one drive motor 20 or the like is required, so that the number of parts and cost can be reduced.
[0102]
Further, the first and second protrusions 38 and 40 are formed higher than the chassis bottom surface 11 than the first and second recesses 37 and 39 of the third gear 34, so that The first and second detecting portions 51 and 55 can detect only the first and second protrusions 38 and 40 of the first motor, and the timing to start, temporarily stop, reverse, and stop one drive motor can be determined. Thus, the detection can be performed easily and reliably.
[0103]
In addition, since the ejection of the hard disk 131 is controlled by the control unit 110, the ejection operation can be performed at the best timing as the recording / reproducing apparatus 1, and the hard disk 131 is ejected by mistake during the recording / reproduction. Can be prevented from being damaged.
[0104]
Next, a case will be described in which a recording / reproducing apparatus controlled by a host computer or the like according to the second embodiment of the present invention, for example, a recording / reproducing apparatus is connected to the host computer via a USB (Universal Serial Bus) or the like.
[0105]
FIG. 19 is a block diagram illustrating the relationship between the recording / reproducing device and the host computer according to the second embodiment of the present invention.
[0106]
As shown in FIG. 19, the recording / reproducing device controlled by the host computer includes the recording / reproducing device 1, the host computer 201, and the like.
[0107]
Here, since the configuration of the recording / reproducing apparatus 1 is the same as that of the first embodiment, the same reference numerals are given and the description is omitted.
[0108]
However, the ejection recording medium determination mechanism 117 stored in the software storage unit 115 of the control unit 110 determines whether the first ejection button 102 or the second ejection button 103 has been pressed, In response to the ejection request 131, it is determined whether the ejection is to be performed from the hard disk 131 desired to be ejected, that is, either the first insertion slot 2 or the second insertion slot 3. The determined information is output to the discharge possibility determination mechanism 118, the discharge pre-processing mechanism 119, and the drive motor control mechanism 121 under the control of the CPU 111.
[0109]
The discharge possibility determination mechanism 118 also stored in the software storage unit 115 determines whether or not there is a hard disk 131 to be discharged, and whether or not the hard disk 131 to be discharged cannot be discharged because recording or playback is in progress. In addition, it is determined whether or not a discharge regulation signal or the like is input from the host computer 201, and the information is output to the discharge pre-processing mechanism 119 and the drive motor control mechanism 121 under the control of the CPU 111.
[0110]
For example, when the hard disk 131 inserted into the recording / reproducing apparatus 1 and the host computer 201 exchange data, the host computer 201 prohibits the ejection of the hard disk 131 to protect programs and data. .
[0111]
The host computer 201 may be an ordinary personal computer, for example, and may include an interface unit for connecting to an external device, an input / output unit such as a keyboard, a display and a speaker, and a control unit.
[0112]
Here, the control unit stores, for example, a CPU (Central Processing Unit) for processing, a RAN (Random Access Memory), a ROM (Read Only Memory), a data storage unit storing various data, and various software. Software storage unit and the like.
[0113]
Next, the operation of the recording / reproducing apparatus 1 and the host computer 201 configured as described above will be described based on FIGS. 1 and 8 to 18 and FIGS. 19 and 20.
[0114]
Here, FIG. 20 is a flowchart of the ejection of the hard disk 131 as an example of the recording medium under the control of the host computer.
[0115]
A case where the hard disk 131 inserted into the first insertion slot 2 is ejected as shown in FIGS. 12 and 17 will be described.
[0116]
First, as shown in FIG. 1, the first eject button 102 of the operation panel 101 of the recording / reproducing apparatus 1 is pressed, and information on the pressing of the first eject button 102 or insertion from the host computer 201 into the first insertion slot 2 is performed. When the ejection command of the hard disk 131 is input to the control unit 110 as shown in FIG. 19, the power switch is controlled by the control power switch lock mechanism 116 of the CPU 111 so that the power is not cut off during the ejection operation of the hard disk 131. Is locked (ST201).
[0117]
Next, the CPU 111 outputs information from the first eject button 102 or the host computer 201 to the ejection recording medium determination mechanism 117, and the ejection recording medium determination mechanism 117 outputs information based on the information from the first ejection button 102 or the host computer 201. It is determined that the insertion port to be discharged is the first insertion port 2 (ST202). The determination information is input to the discharge possibility determination mechanism 118 under the control of the CPU 111.
[0118]
At this time, if there is information indicating that the first eject button 102 has been pressed and command information for ejecting the hard disk 131 of the second insertion slot 3 from the host computer 201, for example, the ejection recording medium determination mechanism 117 Thus, the information on the first eject button 102 side is processed with priority. Of course, the command information from the host computer 201 can be prioritized depending on how the discharge recording medium determination mechanism 117 is set.
[0119]
Further, the discharge possibility determination mechanism 118 to which the determination information has been input detects and determines whether the hard disk 131 is inserted into the first insertion slot 2 by using, for example, a detection switch provided on the partition plate 14 (ST203). . As a result, when it is determined that the hard disk 131 is not inserted into the first insertion slot 2, there is no hard disk 131 to be ejected, so that the state returns to the state before ST201, so that useless operation can be prevented.
[0120]
Next, when the ejection possibility determination mechanism 118 determines that the hard disk 131 is inserted into the first insertion slot 2, the information is input to the controlled ejection pre-processing mechanism 119 of the CPU 111, and the pre-ejection processing is performed. The mechanism 119 performs processing such as storage of information and files relating to the hard disk 131 inserted into the first insertion slot 2 (ST204). As a result, it is possible to prevent the data and the like of the hard disk 131 from being damaged by the discharging operation.
[0121]
Further, under the control of the CPU 111, when pre-discharge processing such as storage of a file by the pre-discharge processing mechanism 119 is completed, the information is input to the discharge possibility determination mechanism 118, and the discharge possibility determination mechanism 118 determines that the discharge prohibition factor that prevents other discharges has occurred. It is determined whether or not there is (ST205).
[0122]
For example, in the case where the recording / reproducing apparatus 1 itself is recording or reproducing the hard disk 131 inserted into the first insertion slot 2, the information is input to the controllable discharge possibility determination mechanism 118 of the CPU 111, The discharge possibility determination mechanism 118 determines that the discharge is prohibited, and returns to the operation before ST203 in order to restrict the discharge operation of the hard disk 131 inserted into the first insertion slot 2. As a result, the discharging operation can be started when it is most convenient for the recording / reproducing apparatus 1.
[0123]
Next, when it is determined in ST205 that the ejection is not in the ejection prohibition state, the ejection possibility determination mechanism 118 outputs the ejection request information of the hard disk 131 from the first insertion port 2 to the host computer 201.
[0124]
On the other hand, when the ejection prohibition information is input from the host computer 201 to the control unit 110, the ejection possibility determination mechanism 118 judges that the host computer 201 does not permit ejection of the hard disk 131 from the first insertion slot 2. (ST206), the state returns to the state before ST201. Thus, when the hard disk 131 and the host computer 201 are exchanging information, it is possible to prevent the hard disk 131 from being ejected and the data from being damaged, and to perform the ejection operation at the most convenient time for the host computer 201. Can be.
[0125]
When the ejection permission information from the host computer 201 is input to the ejection possibility determination mechanism 118 under the control of the CPU 111, the ejection possibility determination mechanism 118 allows the host computer 201 to permit ejection of the hard disk 131 from the first insertion slot 2. (ST206), the information is input to the controlled detection switch information mechanism 120 of the CPU 111, and both the first detection switch 53 and the second detection switch 57 are electrically conductive (electrically on). It is determined whether or not (ST207).
[0126]
Accordingly, for example, if it is determined that both the first detection switch 53 and the second detection switch 57 are electrically ON, the first actuator 54 is formed on the third gear 34 as shown in FIGS. The second actuator 58 of the second detection switch 57 is similarly pressed and pushed by the second projection 40 formed on the third gear 34. It will be.
[0127]
Therefore, the first protrusion 38 formed on the third gear 34 at the first detection switch 53 and the second protrusion 40 formed on the third gear 34 at the second detection switch 57 come. The pin 36 for ejecting the recording medium is located at the rear end of the partition plate 14, which is the initial position, and the third gear is rotated on either side of the first insertion port 2 and the second insertion port 3. It becomes possible.
[0128]
On the other hand, when it is not determined that both the first detection switch 53 and the second detection switch 57 are electrically ON, for example, both the first detection switch 53 and the second detection switch 57 are not electrically conductive ( When it is determined that the switch is in the “electrically off” state, both the first detection switch 53 and the second detection switch 57 are in an incomplete position, for example, as shown in FIG. 11 or FIG. In the first recess 37 of the third gear 34, the second detection switch 57 is at a position where the third gear 34 is partially cut linearly.
[0129]
In such a case, there is a possibility that the hard disk 131 in the first insertion slot 2 has already been ejected or some abnormal state has occurred, so the operation before ST201 is performed without instructing the start of the ejection operation. Will be returned to.
[0130]
Also, for example, when it is determined that only the second detection switch 57 is electrically ON, the first detection switch 53 is connected to the first recess 37 of the third gear 34 as shown in FIG. 12 or FIG. The detection switch 57 is located at the first protrusion 38 of the third gear 34, and the hard disk 131 in the first insertion slot 2 has already been ejected and the third gear 34 is being rotated in the reverse direction, or somehow. Since an abnormal state may occur, the operation returns to the operation before ST201 without instructing the start of the discharging operation.
[0131]
Next, it is determined that both the first detection switch 53 and the second detection switch 57 are electrically turned on, and the information and the first insertion port, which is an insertion port to be discharged by the discharge recording medium determination mechanism 117, are determined. When the determination information to select 2 is input to the controllable drive motor control mechanism 121 of the CPU 111, the drive motor control mechanism 121 determines that the worm gear 31 of the gear unit 30 has a left-hand thread, for example. Under the control of the CPU 111, the CPU 122 is instructed to supply a current to the drive motor 20 so that the motor shaft 21 of the drive motor 20 rotates clockwise (direction C shown in FIG. 9) when viewed from the shaft side. Based on the information, the power supply unit 122 supplies a necessary current to the drive motor 20, and the drive motor 20 causes the motor shaft 21 to rotate clockwise as viewed from the shaft side (ST2). 8).
[0132]
As a result, the third gear 34 starts to rotate clockwise (direction A in FIG. 9) as shown in FIG. 9, and the cam body 81 also starts to rotate at the same time. The first lock lever 82 pressed and closed by 90 is opened in the direction B in FIG. 9 around the first lock lever fulcrum shaft 85, and the first locking portion provided on the first lock lever 82 accordingly. The hooked portion of 83 starts to move in the locking groove left 140 of the locking portion left 137 of the hard disk case 133 described later.
[0133]
Next, when the third gear 34 further rotates as shown in FIGS. 10 and 15 (in the direction A in FIG. 10 and the direction D in FIG. 15), the first lock lever 82 (the first locking portion 83) is moved. Further, as the cam body 81 rotates, it is further opened in the direction B in FIG. 10 (the direction E in FIG. 15), and the portion where the first locking portion 83 provided on the first lock lever 82 is caught is formed by the hard disk case 133. The first locking portion 83 that is disengaged from the locking groove left 140 of the locking portion left 137 and is provided on the first lock lever 82 for a predetermined period of time releases the lock without returning to the original position due to the shape of the cam body 81. Keep the position of.
[0134]
At this time, the first detection switch 53 and the second detection switch 57 are not pushed by the first actuator 54 and the second actuator 58, and are electrically off. Further, the detection switch information mechanism 120 can determine that the ejection operation of the hard disk 131 of the first insertion slot 2 is being performed by inputting the electrically turned off information under the control of the CPU 111. Become.
[0135]
Further, when the third gear 34 rotates as shown in FIGS. 11 and 16 (in the direction A in FIG. 11 and the direction D in FIG. 16), the recording medium pushing pin 36 of the third gear 34 is moved to the hard disk case 133. By pressing the vertical wall 138 as it is, the ejection of the hard disk 131 starts. At this time, the first locking portion 83 provided on the first lock lever 82 keeps the unlocked position, so that the hard disk 131 is smoothly discharged.
[0136]
Next, when the third gear 34 further rotates, the first protrusion 38 of the third gear 34 pushes the second actuator 58 of the second detection switch 57 from the right as shown in FIGS. While the detection switch 57 is electrically turned on, the first detection switch 53 is in the first recess portion 37, and there is nothing to push the first actuator 54, so that the first switch 53 is electrically turned off. Based on the information, the detection switch information mechanism 120 determines that only the second detection switch 57 has been electrically turned on (ST209).
[0137]
Further, only the second detection switch 57 is not electrically turned on. For example, when it is determined that both the first detection switch 53 and the second detection switch 57 are electrically turned on, the initial position is still not determined due to some abnormality. Therefore, the operation returns to the operation before ST208.
[0138]
Next, when the detection switch information mechanism 120 determines that only the second detection switch 57 is electrically ON, the information that only the second detection switch 57 is electrically ON is controlled by the CPU 111. The driving motor control mechanism 121 is input from the detection switch information mechanism 120 to the driving motor control mechanism 121, and the driving motor control mechanism 121 outputs a command to the power supply unit 122 to temporarily stop the current supply to the driving motor 20. The unit 122 temporarily stops the current supply to the driving motor 20, and the driving motor 20 temporarily stops (ST210). At this time, the hard disk 131 is in a state where it can be manually removed from the first insertion slot 2, and the ejection of the hard disk 131 itself is completed.
[0139]
Next, the drive motor control mechanism 121 reverses the rotation of the drive motor 20 and applies a predetermined current to the power supply unit 122 so that the third gear 34 rotates in the F direction in FIG. 13 and the H direction in FIG. The power supply unit 122 supplies a current to the drive motor 20 so that the drive motor 20 rotates in the reverse direction (ST211).
[0140]
Further, the third gear 34 rotates in the direction F of FIG. 13 and the direction H of FIG. 18, and the first actuator 54 of the first detection switch 53 is moved by the first protrusion 38 of the third gear 34 as shown in FIG. When the second actuator 58 of the second detection switch 57 is pressed by the second projection 40 of the third gear 34 to be electrically turned on, the detection switch information mechanism 120 to which the information has been input is detected. It is determined whether both switches are electrically on (ST212).
[0141]
Here, when the detection switch information mechanism 120 determines that both the first detection switch 53 and the second detection switch 57 are electrically on, the determination information is transmitted under the control of the CPU 111 and the detection switch information mechanism 120 Is input to the drive motor control mechanism 121, and the drive motor control mechanism 121 outputs a command to the power supply unit 122 to stop supplying current to the drive motor 20, whereby the power supply unit 122 Is stopped, and the drive motor 20 stops its rotation (ST213).
[0142]
If the detection switch information mechanism 120 does not determine that both of the detection switches are in the electrically ON state, for example, some abnormality has occurred and the recording medium pushing pin 36 of the third gear 34 is still in contact with the partition plate. Since there may be a case where it has not returned to the initial position at the rear end of 14, the operation returns to the operation before ST211.
[0143]
Next, when the power supply unit 122 stops supplying current to the drive motor 20 according to a command from the drive motor control mechanism 121 and the information is input to the power switch lock mechanism 116, the power switch lock mechanism 116 The lock of the power switch is released so that the power switch under the control of (1) is activated (ST214). As a result, the recording / reproducing apparatus 1 controlled by the host computer 201 ends a series of discharging operations of the hard disk 131.
[0144]
In addition, the ejection of the hard disk 131 in the first insertion slot 2 has been described. However, when the second eject button 103 is pressed or the ejection command of the hard disk 131 inserted into the second insertion slot 3 is issued from the host computer 201. Also in this case, the ejection can be performed according to the present embodiment in the same manner as in the case of the first eject button 102 or the case where the ejection instruction of the hard disk 131 inserted into the first insertion slot 2 is issued from the host computer 201.
[0145]
When the second eject button 103 is pressed or when the host computer 201 issues a command to eject the hard disk 131 inserted into the second insertion slot 3, the hard disk 131 in the second insertion slot 3 is ejected. The direction in which the drive motor 20 starts to rotate first is counterclockwise, the direction in which the third gear 34 first rotates is also counterclockwise, and the movement of the cam body 81 due to the shape of the cam body 81 is the second lock. The drive motor 20 that has started to rotate counterclockwise by the lever 86 is temporarily stopped when only the first detection switch 53 is pressed by the second protrusion 40 and is electrically turned on.
[0146]
Further, when the second eject button 103 is pressed during the ejection operation of the hard disk 131 in the first insertion slot 2, or when the host computer 201 issues a command to eject the hard disk 131 inserted into the second insertion slot 3, for example, Under the control of the CPU 111, the information is temporarily stored, and after the ejection operation of the hard disk 131 of the first insertion slot 2 is completed, the ejection operation of the hard disk 131 of the second insertion slot 3 is started.
[0147]
As described above, according to the present embodiment, the rotation of one drive motor 20 causes the rotation of the first motor 2 on the circumference around the shaft 35 formed between the first insertion port 2 and the second insertion port 3. A recording medium pushing pin 36 is provided which is movable clockwise when the hard disk 131 in the first insertion slot 2 is ejected, and is movable counterclockwise when the hard disk 131 in the second insertion slot 3 is ejected. Therefore, even if there is one drive motor 20, any of the hard disks 131 inserted into the two insertion ports can be ejected, and the number of components and cost of the recording / reproducing apparatus 1 can be reduced. .
[0148]
Further, the first detection switch 53 and the second detection switch 57 are arranged on the outer circumference of the circumference on which the recording medium push-out pin 36 moves, and the detection signals are output from both the first detection switch 53 and the second detection switch 57. When the rotation of the drive motor 20 is started or stopped when input to the control unit 110 and a detection signal is input to the control unit 110 from only one of the first detection switch 53 and the second detection switch 57 In addition, since the control unit 110 for stopping the rotation of the drive motor 20 and then performing reverse rotation is provided, the discharge of the two hard disks 131 can be accurately controlled even with one drive motor 20.
[0149]
Further, the rotation of the drive motor 20 causes the cam body 81 to rotate about the shaft 35, and the first locking portion that locks the hard disk 131 when the hard disk 131 in the first insertion opening 2 is ejected by the rotation. A first lock lever 82 that opens and closes 83 is provided, and when the hard disk 131 in the second insertion port 3 is ejected, a center line formed between the first insertion port 2 and the second insertion port 3 is sandwiched. And a second lock lever 86 that is disposed equidistantly from the first lock lever 82 and opens and closes the second locking portion 87 that locks the hard disk 131, so that one drive motor 20 The hard disk 131 to be ejected among the hard disks 131 can be unlocked only when the hard disk 131 is ejected. 1 can be locked, and drive motor 20 or the like can be achieved to reduce the number of parts and cost because requires only one.
[0150]
In addition, since the ejection of the hard disk 131 is controlled by the control unit 110, the ejection operation can be performed at the best timing as the recording / reproducing apparatus 1, and the hard disk 131 is ejected by mistake during recording / playback, and This can prevent data from being damaged.
[0151]
Further, the control unit 110 is controlled to start or stop the rotation of the drive motor 20 by a regulation signal output from the host computer 201 which is an arithmetic processing unit for controlling the operation of the recording / reproducing apparatus 1. When the ejection prohibition information is input from the control unit 110 to the control unit 110, the ejection possibility determination mechanism 118 determines that the host computer 201 does not permit ejection of the hard disk 131 from the first insertion port 2, and the ejection operation of the hard disk 131 is performed. Is not started, the discharging operation can be performed at the most convenient time for the host computer 201.
[0152]
In addition, since the restriction signal output from the host computer 201 can be generated as necessary in the file management of the host computer 201, for example, when the hard disk 131 and the host computer 201 exchange data, the hard disk 131 Is discharged and data and the like can be prevented from being damaged.
[0153]
Next, a recording medium such as a hard disk 131 according to a third embodiment of the present invention will be described.
[0154]
FIG. 21 is a schematic perspective view of the rear surface of the hard disk 131 according to the third embodiment of the present invention, FIG. 22 is an explanatory diagram showing a state in which the rear surface of the hard disk 131 approaches the first locking portion 83 of the recording and reproducing device 1, and FIG. FIG. 24 is an explanatory diagram of the state where the first taper portion 84 of the first locking portion 83 is further pushed from FIG. 22, and FIG. 24 is an explanatory diagram of the state where the hard disk 131 is locked.
[0155]
The hard disk 131 is formed of, for example, a hard disk main body 132 (not shown) having a hard magnetic medium or the like, a hard disk case 133 surrounding the hard disk main body 132, and the like. As a result, video recording, audio recording, computer data storage, and the like can be performed on the hard disk 131.
[0156]
The hard disk case 133 has an opening in the lower half of the back as shown in FIG. 21, and an I / F (interface) fixed outwardly to, for example, a hard disk substrate 134 at a substantially center of the opening. ) A connector socket 135 is arranged. Thus, the hard disk 131 can exchange data with the slot side via the I / F connector socket 135 and receive power supply for driving the magnetic medium and the like of the hard disk main body 132.
[0157]
Further, in the hard disk case 133, for example, as shown in FIG. 21, a vertical wall 138 against which the recording medium pushing pin 36 of the recording / reproducing apparatus 1 contacts by the rotation of the third gear 34 is provided below the I / F connector socket 135. A locking portion right 136 and a locking portion left 137 are formed on both left and right ends of the vertical wall 138 so as to face each other. Thus, even if the hard disk 131 is inserted into either the first insertion slot 2 or the second insertion slot 3 of the slot 4, either the locking portion right 136 or the locking portion left 137 is moved to the lock lever on the insertion port side. The lock is reliably performed by the formed first locking portion 83 or the second locking portion 87, and the operation is simplified without having to select the insertion slot of the hard disk 131.
[0158]
In addition, as shown in FIG. 21, a locking groove right 139 and a locking groove left 140 formed continuously with the vertical wall 138 are provided in the locking portion right 136 and the locking portion left 137, respectively. A tapered portion right 141 and a tapered portion left 142 are respectively formed on the front surfaces of the overhanging portions which are the catching portions of the stop portion right 136 and the locking portion left 137. As a result, the first locking portion 83 or the second locking portion 87 on the recording / reproducing apparatus side can be smoothly opened, and the hooked portion can enter the locking groove right 139 or the locking groove left 140.
[0159]
The hard disk case 133 is slidable on both sides with the first left and right guide rails 15 and 16 or the second right and left guide rails 17 and 18 on the slot side when the hard disk 131 enters the slot 4 as shown in FIG. 143 and a rail groove left 144 are formed.
[0160]
Next, an operation of locking the hard disk 131, which is an example of the recording medium configured as described above, to the recording / reproducing apparatus 1 will be described.
[0161]
First, for example, when the hard disk 131 is inserted into the first insertion slot 2 of the recording / reproducing apparatus 1, the right rail groove 143 and the left rail groove 144 are slidably fitted with the first left and right guide rails 15 and 16 on the slot side. Then, when the hard disk 131 is pushed as it is, the locking portion left 137 of the hard disk case 133 approaches the first locking portion 83 of the slot 4 as shown in FIG.
[0162]
When the hard disk 131 is further pushed, as shown in FIG. 23, the first tapered portion 84 of the first locking portion 83 comes into contact with the tapered portion left 142 of the locking portion left 137 of the hard disk case 133, and the first first. The locking portion 83 overcomes the tension of the tension coil spring 90 of the slot 4 by the function of the tapered portion, and rotates in the direction I in FIG.
[0163]
Next, when the first tapered portion 84 of the first locking portion 83 exceeds the tapered portion left 142 of the locking portion left 137 of the hard disk case 133 and reaches the locking groove left 140 of the hard disk case 133, as shown in FIG. As described above, the first locking portion 83 of the slot 4 rotates in the J direction by the tension of the tension coil spring 90, and the portion where the first locking portion 83 of the slot 4 is caught is in the locking groove left 140 of the hard disk case 133. As a result, the hard disk 131 is securely locked to the recording / reproducing apparatus 1.
[0164]
The same applies to the case where the hard disk 131 is inserted into the second insertion slot 3, but the locking portion right 136 of the hard disk case 133 is locked by the second locking portion 87 of the slot 4.
[0165]
As described above, according to the present embodiment, the locking portions that lock the slots 4 are formed at both ends of the rear surface of the hard disk case 133 that houses the hard disk main body 132. The hard disk 131 can be locked to the recording / reproducing device 1 even if the hard disk 131 is inserted into the storage device, so that the hard disk 131 can be prevented from being detached during data exchange.
[0166]
Locking grooves formed at both ends on the rear surface of the hard disk case 133 are locking grooves formed on the right and left sides 139 and 140, which are formed opposite to each other, so that the locking portion of the locking portion of the slot 4 can be locked. And the right and left tapered portions 141 and 142 formed on the front surface of each locking groove, the hard disk 131 can be securely locked by the recording / reproducing device 1 and the locking operation itself can be smoother.
