Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information storage device using a cartridge containing an information recording medium such as an optical disk drive device and an audio / video recording tape recorder device.

2. Description of the Related Art Conventional information storage devices of this type include, for example, a magnetic recording type floppy disk drive device and an optical magnetic recording type or phase change type optical disk drive device.

In these devices, a cartridge containing a floppy disk or an optical disk, which is an information recording medium, is inserted into the device and mounted at a predetermined position in the device, and then the information recording medium is rotated to write information by a magnetic head or an optical head. Recording and playback are performed.

When the cartridge is taken out of the apparatus, the cartridge is taken out by the force by pushing the take-out button facing the outside of the apparatus or turning the turning lever. (For example, Japanese Utility Model Laid-Open No. 62-106396) Also, after holding a cartridge containing an information recording medium to be inserted into the device, a motor is used to transfer the device to a predetermined mounting position and from the mounting position to a discharging position. A device that employs a so-called auto-loading method (for example, Japanese Patent Application No.
No. 62-230101) is also considered.

However, when the cartridge can be directly taken out of the apparatus by the operation force from the outside of the apparatus by pressing the take-out button provided on the front surface of the apparatus, the information is recorded in the information recording medium. The recording of important information that may occur during the process cannot be performed in a highly reliable state. On the other hand, it is conceivable that at least during recording, a blocking lever operated by a plunger or the like prohibits an operating force from outside the apparatus by an operator. However, in this case, in order to take out the cartridge from the apparatus, it is necessary for the user to carefully observe that the recording state has ended and to perform the taking-out operation again,
Along with the complexity of the operation, it tends to cause an erroneous operation depending on the timing of the recording start or end and the operation force. It is also conceivable that the operating force from the outside of the apparatus is stored once in terms of the mechanism configuration and the plunger is operated to perform the take-out operation after the recording state ends, but the mechanism becomes extremely complicated.

On the other hand, a first object of the present invention is to prevent the information recording medium from being accidentally taken out while recording the take-out button provided on the front surface of the apparatus, and to achieve high reliability with a simple operation and a very simple structure. The purpose is to make it possible to eject the cartridge containing the information recording medium to the outside of the apparatus.

A second object of the present invention is to realize mounting and ejection of a cartridge containing an information recording medium to and from an apparatus with an extremely simple structure, and at the same time, when an eject button provided on the front surface of the apparatus is erroneously recorded during recording. The purpose is to achieve the first objective without taking out.

In addition, as a problem from one viewpoint, since the plunger cannot operate when the power is cut off due to a power outage or the like, it is possible to take out the information recording medium recording sensitive information from the device and store it. Do not turn on the power in a device that uses a motor or an auto-loading system that uses a motor to mechanically hold the cartridge to be inserted and transfer it to a specified position. If it is inserted, the cartridge cannot be similarly taken out unless the power is turned on. On the other hand, a window or hole for emergency ejection operation used at the time of power failure etc. is provided on the front of the device and tools such as a driver are inserted and the lock by the plunger is released by the operating force from outside the device by the operator. It is conceivable to perform a take-out operation. In the case of the auto loading method using a motor,
In order to secure the mounting / discharging speed of the cartridge and a sufficient driving force, a speed reducing mechanism including a worm / worm wheel is generally adopted, but it is not necessary to rotate the worm from the worm wheel side to which the cartridge mounting means is connected. Since it is extremely difficult to load and is practically difficult, either rotate the worm directly for an extremely large number of times required for the discharging operation, or cut off the drive force transmission system to the mounting means once and place it in a position with less drive load. It is conceivable to insert a tool through a similar window or hole to apply an operating force. However, in the case of rotating the worm a number of times, in addition to the complexity, unless the operation force from outside the device is detected by detecting completion of the discharging operation, the speed reducing mechanism is exceeded beyond the moving range of the mounting means. Since it is operated with a large force passing through, there is a risk of destroying the device mechanism, and it is easily presumed that this avoidance mechanism becomes extremely complicated.
Even when the driving force transmission system reaching the mounting means is cut off and a driving force is applied, the mechanism may become complicated and it may be difficult to secure the reliability of engagement when the driving force transmission system is connected again. . Further, if a window or a hole which is not normally used is provided on the front surface of the apparatus, not only the appearance is impaired, but also a tool may be mistakenly inserted and the cartridge may be taken out. In addition, when operating from narrow holes or windows, it is generally difficult to operate, and special tools are required to make it easier. And in the unlikely event that the tool is lost, the removal operation is naturally impossible. Further, when the window is formed on the front surface, a new device component such as a sliding door that normally covers the window is required.

On the other hand, a third object of the present invention is to make it possible to easily take out the cartridge containing the information recording medium even when the power supply to the device is cut off at the time of a power failure or the like.

Further, a fourth object of the present invention is to provide a sufficient space necessary for operation without providing a window or a hole in the front of the device with an operation force from the outside of the device when power supply to the device is cut off at the time of power failure or the like. It is to ensure that it can be easily added to the device without using a special tool such as a driver.

Means for Solving the Problems In order to achieve the above first, third and fourth objects, an information storage device of the present invention is provided on the front surface of the device for inserting a cartridge containing an information recording medium into the device. A predetermined opening inside the apparatus, the rotation lid covering the opening, and the rotation lid being rotated to interlock with an insertion operation of inserting the cartridge into the apparatus through the opening. A cartridge mounting means to be mounted at a position, a cam means that does not engage during the mounting operation of the cartridge and that engages with the cartridge mounting means only during the discharging operation to move the cartridge mounting means in the discharging direction, and the cam means. A position inside the device where a driving means for driving and an engaging end capable of transmitting an operating force from the outside of the device in a direction in which the cartridge is discharged to the outside of the device can be operated from the opening. And an operating force transmission means facing the above.

In order to achieve the second object, the information storage device of the present invention is a cartridge holder that accommodates a cartridge containing an information recording medium at the time of insertion into the device and is capable of ascending / descending only in the thickness direction of the inserted cartridge. A slide cam that engages with the cartridge and raises and lowers the cartridge holder by its movement, an abutting portion that abuts on the front surface of the cartridge to be inserted, and a height position of the cartridge holder to be regulated. A lock member having a restricting portion in contact with the slide cam and the lock member so as to generate a biasing force in a direction in which the slide cam lowers and mounts the cartridge holder, and in a direction in which the lock member prevents insertion of a cartridge. It has a cartridge mounting means composed of an elastic member stretched between Than it is.

In the means for achieving the above-mentioned first, third and fourth objects, the cam means does not engage during the cartridge mounting means and the cartridge mounting operation, but engages only during the discharging operation to perform the discharging operation. Moreover, since the cam means is driven only by the driving means for driving it, it does not interfere with the mounting operation as a load during the mounting operation of the cartridge, and by pressing the normal eject button, the cartridge is ejected even during recording. Avoid the inconvenience caused by taking out halfway during recording, such as a device with a mechanical structure that allows
After the recording mode is completed and the running or rotation of the information recording medium is stopped, the cam means can be operated to move the cartridge mounting means in the ejecting direction in a safe next period. The cartridge can be ejected by operating the operation force transmitting means provided inside the apparatus from the opening portion into which the cartridge is inserted, which is not normally touched by a finger even when the cartridge is cut off.

Of course, when the slide cam 17 moves in the reverse direction, the cartridge holder 20 rises. An opener arm 25 is provided at the upper part of the cartridge holder 20. One of the opener pins of the above-described cartridge 3 is erected at one end of the cartridge holder 20 and is pivotally supported by a shaft 26. And opener arm 25
Is an opener spring 28 which is a tension spring whose one end is locked to the cut-and-raised portion 20E of the cartridge holder 20.
It is locked at 25A, and is thereby urged to rotate in a direction that prevents the cartridge 3 from being inserted. The rotation position of the cartridge holder 20 is regulated by one end of the long hole portion 20F of the cartridge holder 20 so that the rotation position of the cartridge holder 20 can enter the concave portion 3B of the cartridge 3. Further, an opener guide 29 is provided on the side of the opener pin 27 in order to prevent the opener arm 25 from floating during rotation. On the chassis 8,
A holder lock 30 is provided which is slidably guided on the chassis 8 by the holder guide shaft 23 and the shaft 31 which are set up. The holder lock 30, which is the lock member of the cartridge holder 20, comes into contact with the cartridge 3 inserted into the cartridge holder 20 at the cartridge abutting portion 3C as shown in FIGS. 2 and 3, and escapes to the cartridge holder 20. It has an abutting portion 30A located inside the portion 20C, and a regulating portion 30B that normally abuts on the bottom surface of the cartridge holder 20 and locks and regulates its height. Also, the locking end 30C of the holder lock 30 and the locking end 17C of the slide cam 17

Cartridge contact part 3 of the cartridge 3 inserted in 30A
When it comes into contact with C, an urging force is generated in a direction that prevents its insertion, and at the same time, the arrow 40 in FIG.
It gives a biasing force in the direction. As a result, the cartridge 3 inserted into the cartridge holder 20 assembled to the slide cam 17 through the opening 5A is urged so as to descend in the thickness direction, and the descending movement position is regulated by the holder lock 30. It is regulated by the portion 30B, and the movement position of the slide cam is also regulated at the same time. The position of the holder lock 30 by the urging force of the tension spring 32 is restricted by the holder guide shaft 23 and the shaft 32. On the other hand, the motor 33 is attached to the rear surface of the chassis 8 via the mounting bracket 38, and the worm 34 integrated with the motor 33 meshes with the worm wheel 35 pivotally supported by the mounting bracket 38 to form the worm wheel 35. The integrated pinion part 36 meshes with the outer periphery of the rotary cam 19 which is also axially supported by the mounting bracket 38, and the slide cam
The cam portion 19A arranged at a position where it can be engaged with the cam follower pin 18 that is planted on the 17 is rotated. As shown in FIG. 2, the rotary cam 19 has a rotational position detecting portion 19C, which is provided with protrusions 19C 'having different radii of rotation, and the protrusions 19C' detect the rotation angle. A switch 37 is provided. When the cartridge 3 is inserted, the relative position between the cam follower pin 18 and the cam portion 19A of the rotary cam 19 is such that the slide cam 17 together with the cam follower pin 18 reaches the position shown by the broken line in the figure as shown in FIG. It is in a positional relationship that does not hinder movement. Further, the slide cam 17 is provided with an elongated hole portion 17D as shown in FIGS. 1 and 4, and an operation from the outside of the device rotatably supported by a shaft 43C erected in the chassis 8 is provided therein. A rotation lever 43, which is an operation force transmission unit that transmits a force to the slide cam 17, is engaged by a shaft 43A.

The rotary lever 43 is provided with an engaging end 43B for the one which gives an operating force from outside the device, and the slide cam 17
When is moved to the position shown by the broken line in FIG. 4, it is similarly rotated to the position shown by the broken line.

At this time, the engaging end 43B is located below the cartridge 3 mounted in the device 1 as shown in FIG. 5, and is fitted to the opening 5A of the front panel 5 such as a tip of a knock type pencil 44. It is designed so that it can be pushed with the tips of personal items.

The operation of the configuration of the above embodiment will be described below. First, as shown in FIG.
Rotating lid 6 in opening 5A provided in front panel 5 of
When it is inserted into the cartridge holder while rotating, the opener pin 27 enters the concave portion 3B of the cartridge 3 in the process, and when the insertion operation is further advanced, the opener arm 25 rotates and the slide shutter of the cartridge 3 moves. 4 slide the cartridge 3 window
The 3D is released to expose the built-in optical disc 2 to the objective lens 10. As shown in FIG. 2, when the cartridge 3 is further inserted in the direction of the arrow 39, the cartridge 3 and the cartridge contact portion 3C are holder locked.
The holder lock 30 is brought into contact with the contact portion 30A of 30 to move the holder lock 30 against the tension spring 32.

Meanwhile, the position of the slide cam 17 is biased in the direction of the arrow 39 by the tension spring 32, and the cartridge holder 30 assembled therein is inserted into the cartridge 3
The holder lock 30 is regulated by the regulating portion 30B of the holder lock 30.

Then, when the cartridge 3 is further advanced, the height of the cartridge holder 20 is not regulated by the regulation portion 30B, and the slide cam 17 is moved in the direction of arrow 40 by the urging force of the tension spring 32 as shown in FIG. At the same time, the cartridge 3 is moved together with the cartridge holder 20 in the direction of arrow 41, and the cartridge 3 is mounted at a predetermined position on the chassis 8 by the positioning pin 15 and the height determining pin 16 on the chassis 8. In this case, the holder lock 30
Is determined by the side surface of the restriction portion 30B contacting the cartridge holder 20, and at the same time, the contact portion 30A is disconnected from the cartridge contact portion 3C of the cartridge 3 and the position of the cartridge 3 is determined by the positioning pin 15. However, this is because the cartridge 3 has the restriction portion 30B.
It is obtained by setting the position at which the regulation to the cartridge holder 20 by the above is slightly moved to the position in the insertion direction of the cartridge 3.

Also, when the insertion is too deep, the regulation of the insertion position is
A pair of holder guide shafts 23, 24 set in the chassis 8
When the escape portion 20C of the cartridge holder 20 whose movement direction is restricted to contact with the contact portion 30A of the holder lock 30, the other is cut and raised portion 20D of the cartridge holder 20 shown in FIG. And the inclined portion 3A of the cartridge 3 come into contact with each other. As shown in FIG. 4, the relative position between the rotary cam 19 and the cam follower pin 18 erected on the slide cam 17 upon completion of the above mounting operation is such that the cam follower pin 18 is blocked by the cam portion 19A of the rotary cam 19 as shown in FIG. Without moving to the position shown by the broken line in the figure. Further, as described above, in this state, the operating end 43A of the rotating lever 43 is in a state where it can effectively receive the operating force from the outside of the device shown in FIG.
After the mounting operation is completed, the optical disk 2 is irradiated with laser light through the objective lens 10 to perform the information recording / reproducing operation.

Next, regarding the operation of taking out the cartridge 3, first, by pressing the eject button 5B provided on the front panel 5 shown in FIG. After confirming that the rotation of the optical disk 2 is stopped by a system controller (not shown) using a microcomputer or the like, the motor 33 is rotated, and thereby the rotary cam 19 is rotated in the arrow 42 direction in FIG. . Then, the cam follower pin 18 of the slide cam 17 at the position corresponding to the broken line causes the cam portion 19A to move the cam follower pin 18 in the outer peripheral direction of the rotary cam 19, and the arrow 40 shown in FIG.
It moves in the opposite direction to the tension spring 32, so that the cartridge holder 20 also rises along with the cartridge 3 in its thickness direction. Eventually, when the raised position of the cartridge holder 20 exceeds the height of the restriction portion 30B of the holder lock 30, the holder lock 30 enters in the direction opposite to the arrow 40 by the urging force of the tension spring 32, and at the same time, the cartridge 3 is inserted. It pushes out in the discharge direction at the contact portion 30A. The rotation of the rotary cam 19 is stopped after the discharging operation of the cartridge 3 is completed and further rotated to the rotation position shown in FIG. 4, because the projection 19C ′ of the rotation detection unit 19C of the rotary cam 19 is a detection switch. 37
Is detected by hitting, and the rotation of the motor 33 is stopped. To remove the cartridge 3 containing the optical disc 2 from the apparatus during the discharging operation or after the power supply is cut off due to a power failure or the like after the mounting is completed, as shown in FIG.
As described above, the engaging end 43B of 43 is pushed by the tip of the personal belongings such as the knock type pencil 44 to push the engaging end 43B to rotate the rotating lever 43 as shown in FIG. It is possible by moving from the position to the position indicated by the solid line. At this time, even if the cam portion 19A with the rotary cam 19 is moved at an arbitrary rotation angle, even if the cam follower pin 18 which is erected on the slide cam 17 moves in the outer peripheral direction by the movement range necessary for the ejection operation of the cartridge 3, A predetermined area is released in the outer peripheral direction so as not to interfere.

As described above, the information recording medium is taken out by mistakenly pressing the ejection button of the cartridge provided on the front surface of the apparatus during recording as in the apparatus having the normal mechanical structure which is the first object of the present invention. In order to enable a cartridge containing an information recording medium to be ejected to the outside of the apparatus with high reliability with a simple operation and with an extremely simple structure, In the embodiment, the cartridge mounting means for mounting the cartridge containing the optical disk 2) at a predetermined position in the apparatus in association with the insertion operation into the apparatus and the cartridge mounting means not engaged during the mounting operation of the cartridge and only during the discharging operation. Cam means for engaging with the cartridge mounting means to move the cartridge mounting means in the discharging direction (rotary cam 19 in the embodiment), and driving means (motor) for driving the cam means. 33) is intended to constitute implemented by the.

As a result, during recording on the information recording medium, the cartridge is directly ejected from the device by an operation force outside the device such that the ejection button of the cartridge provided on the front of the device is erroneously pressed like the device having a normal mechanical structure. There is no inconvenience of being taken out and the information can be recorded with high reliability.

Then, the operation force from outside the device by the operator is prohibited during recording by the plunger or the like, and the cause of erroneous operation when the user carefully takes out the end of the recording state by carefully observing the display lamp or the like can be eliminated. Further, in terms of the mechanical structure, a complicated mechanical structure such as once storing the operation force from the outside of the apparatus and operating the plunger to take out after the recording state is completed is not required.

The second object of the present invention is to realize the mounting and ejection of the cartridge containing the information recording medium to and from the apparatus with an extremely simple structure, and the erroneous removal operation of the cartridge during the recording which is the first object. To prevent this from happening, a cartridge holder that accommodates a cartridge containing an information recording medium at the time of insertion into the device and that can be raised and lowered only in the thickness direction of the inserted cartridge, and a cartridge holder. A slide cam that engages and moves up and down the cartridge holder by its movement,
A lock member having an abutting portion that abuts the front surface of the cartridge to be inserted and a regulating portion that abuts to regulate the height direction position of the cartridge holder, and a direction in which the slide cam lowers the cartridge holder and the lock member is the cartridge. An elastic member stretched between the slide cam and the lock member so as to generate a biasing force in a direction that prevents the insertion of the
This is realized by a cam means that is not engaged when the slide cam moves in the direction of lowering the cartridge, but engages so as to move only in the direction of raising the cartridge, and a drive means that drives the cam means.

As a result, the cartridge which is inserted and stored in the cartridge holder is lowered and mounted to a predetermined position by a single elastic member, and a driving force for discharging the cartridge to the outside of the apparatus can be secured, and a cartridge mounting means can be provided with an extremely simple structure. At the same time, it is possible to eliminate the inconvenience of erroneously taking out the cartridge during recording.

The third object of the present invention is to enable the cartridge containing the information recording medium to be easily taken out when the power supply to the device is cut off at the time of power failure or the like.
A cartridge mounting means for mounting a cartridge containing an information recording medium at a predetermined position in the apparatus, and a cam means for engaging in the cartridge mounting means only for the discharging operation and moving in the discharging direction without engaging during the mounting operation of the cartridge. And driving means for driving the cam means, and operating force transmitting means for transmitting the operating force from the outside of the apparatus to the cartridge mounting means in the direction in which the cartridge is discharged to the outside of the apparatus.

As a result, even if the power is cut off due to a power failure or the like, the cam means does not engage with the cartridge mounting means during the mounting operation of the cartridge. The information recording medium in which confidential information is recorded can be taken out from the device and stored. In the case of the auto-loading method using a motor, the rotating shaft of the motor is directly rotated for a very large number of times required for discharging operation, or the driving force transmission system leading to the mounting means is cut off, and the position where the driving load is small When a tool is inserted through the hole provided in the front of the device to apply an operating force, it does not require a complicated structure, and when the rotating shaft of the motor is directly rotated, it is detected that the discharging operation is completed. If the operating force from outside the device is not interrupted, the inconvenience that the device mechanism may be destroyed by operating with a large force beyond the moving range of the mounting means via the reduction mechanism can be eliminated.

A fourth object of the present invention is to provide an operation force from the outside of the device when power supply to the device is interrupted at the time of power failure, etc. To secure the space and to be easily added to the device without using a special tool such as a driver,
It includes an opening provided on the front surface of the apparatus for inserting the cartridge containing the information recording medium into the apparatus, a rotary lid for covering the opening, and a drive source for mounting the inserted cartridge at a predetermined position in the apparatus. The cartridge mounting means and the operating force in which the engaging end capable of transmitting the operating force from the outside of the apparatus to the cartridge mounting means in the direction in which the cartridge is discharged to the outside of the apparatus faces the position inside the apparatus operable from the opening. It is realized by transmission means.

In this way, by arranging the engaging end at the position inside the device rather than on the front of the device, the possibility of accidental operation by pushing without knowing the function is reduced compared to when it is arranged on the front of the device. It is possible. In addition, since the operating force is applied from the opening, it is not necessary to provide windows and holes that are not normally used on the front of the device, and not only can the appearance be maintained, but also when the cartridge is ejected from the nipping holes or windows. Is generally awkward to operate and does not require the special tools needed to make it easy. And when the tool is lost, there is no inconvenience that the take-out operation becomes impossible, and there is no need for new device components such as a sliding door that normally covers the window when the window is configured on the front side. Can also be provided.
