DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording / reproducing apparatus using a disk cartridge containing a disk-shaped recording medium, and a stocker in which one or a plurality of disk cartridges can be mounted is provided with an opening in a front panel. The present invention relates to a disk reproducing apparatus that transfers the data to the inside of a housing via a.

[0002]

2. Description of the Related Art As a conventional disk reproducing apparatus, the following configuration is known as an example of a technique for pulling a cartridge mounted on a stocker into a housing.

[0003] As a first conventional example, it is generally well known that a driving member for pulling a stocker into the inside has a double lever configuration in which a spring is biased. The lever on the slave side is moved in accordance with the movement of the stocker by the operation of pushing the stocker itself, and at the same time, the drive member is pulled in by the drive motor by detecting the position of the moved member. Then, the double lever in the open state is closed to the original angle, and the stocker is transferred into the housing in a state where the double lever operates integrally. The spring force of the double lever prevents breakage of the drive member when operated with excessive pushing force,
It is used to secure the holding force of the discharge position of the stocker against the reaction force for holding the lock when the cartridge is mounted.

[0004] As a second conventional example, Japanese Utility Model Laid-Open No. 4-49 is disclosed.
No. 350 discloses a configuration using a worm and a worm wheel for a drive system for inserting and discharging a magazine.

In this configuration, the last gear and the lever are rotatably arranged on the same axis, and the gear and the lever are connected by a spring to prevent the worm from biting at the end of operation.

[0006]

In the first prior art, since the lever of the driving member has a double structure, the structure is slightly complicated, and when a stocker is pushed in, a reaction force is generated to push it back. Problems such as poor feelings occurred.

In the second conventional example, the worm and the worm wheel are used. However, the worm and the worm wheel are connected by a spring for the purpose of preventing the worm from biting at the end of operation. It is not effective in improving gears and preventing gear breakdown due to external force.

According to the present invention, when a stocker in which one or a plurality of disk cartridges can be mounted is transferred into the housing through an opening in the front panel, the drive gear is prevented from being broken by an excessive pushing operation. Also, a gear drive system capable of stably securing a holding torque against an operation force for mounting a cartridge in a slot of a stocker is realized.

It is another object of the present invention to provide a disk reproducing apparatus capable of easily switching a braking torque of a stocker transfer drive system according to each operation state.

[0010]

In order to solve the above-mentioned problems, a disk reproducing apparatus according to the present invention comprises control means capable of setting a motor terminal to a short or open state according to a predetermined operation mode or position of a stocker. The multi-row worm is set with the number of strips and the lead angle that allow the motor to reverse when the stocker is forcibly pushed in and an external force is applied from the last stage to the motor.

As a result, it is possible to prevent the drive gear from being destroyed by an excessive pushing operation, to stably secure a holding torque against an operation force for mounting the cartridge into the slot of the stocker, and to control a braking torque of the stocker transfer drive system. Can be easily switched in accordance with each operation state.

[0012]

A gear train including a reduction gear including a worm wheel meshing with the multi-worm is provided, and control means for setting a short-circuit between terminals of the transport drive motor when the stocker is at the discharge position is provided. It is assumed that.

Further, the invention according to claim 3 of the present invention provides:
In the above-described configuration, when the stocker at the discharge position is pushed into the housing by manual operation, the conveyance drive is performed based on the detection information of the stocker position detection unit that detects that the stocker has been transferred from the predetermined discharge position by an external force. The motor is electrically connected to rotate the motor in a direction in which the stocker is mounted in the housing.

The invention according to claim 4 of the present invention provides:
A housing provided with a front panel having an opening on one side; a playing means provided inside the housing for recording / reproducing a disk rotatably stored in a disk cartridge; While facing the front panel of the housing, and disposed on the front panel side than the playing means,

It is characterized by comprising control means for switching to a state.

With the above arrangement, when the stocker is pushed in, a rotational force is generated from the subsequent gear after the gear train is decelerated, and the worm and the worm wheel are set to a transmission efficiency that allows rotation from the driven side. Therefore, the rotation is transmitted to the transport drive motor of the drive source. At this time, when the terminals of the transport drive motor are open at both ends, the braking torque of the transport drive motor decreases, so that the pushing load of the stocker can be reduced, and the pressure applied to each drive gear can also be reduced.

Further, when the stocker is at the discharge position,
By making the terminals of the transport drive motor short-circuited, the braking torque of the transport drive motor can be increased, and the force against the pushing force applied to the stocker can be increased. For this reason, it is possible to stably secure a holding torque against an operation force for mounting the disc cartridge on the stocker, which is an operation in the insertion direction toward the same housing.

When the stocker is driven from the inside of the housing in the discharge direction, if there is an obstacle that cannot project to a predetermined discharge position, the power supply in the discharge direction is stopped and the transport drive motor is released between both terminals. By doing so, destruction of the gear can be prevented.

FIG. 8 is a detailed view of a main part showing a transfer route from the stocker in the state of FIGS. FIG. 9 is a schematic diagram of a lifting mechanism for selecting a cartridge to be reproduced. FIG. 10 is a flowchart showing the relation of the mechanism operation according to the state of the slide panel. FIG. 11 is a side view showing a state where the stocker has been transferred to the vicinity of the panel.

First, a stocker for accommodating a disk cartridge and a front slide panel according to the present embodiment will be described.

1 to 3, a front panel 7 is integrally provided on a front surface of the housing 3. The front panel 7 has an opening for the stocker 2 into which the disk cartridge 1 is inserted. Further, a slide panel 8 for shielding the opening is slidably provided on the front panel 7. The height of the opening of the front panel 7 is set to be large as shown in FIGS. 1 and 3 so that the number of stored disk cartridges 1 can be as large as possible. However, the opening of the front panel 7 is
Due to the thickness of the panel edge, the height is smaller than the height of the storage position inside the housing 3.

The front panel 7 is provided with an open / close button 9 for discharging the stocker 2 at a position not blocked by the stocker 2 and the slide panel 8. The slide panel 8 is provided with operation buttons or a display unit (not shown) for operating the playback device. When the opening of the front panel 7 is completely shielded by the slide panel 8, the operation buttons or the display section are electrically connected by closing contacts 10a and 10b provided respectively. When the slide panel 8 is fully opened,
A panel open completion sensor 11 in a detection state is provided on the front panel 7.

In the depth direction of the opening of the front panel 7, a stocker 2 capable of accommodating a plurality of disk cartridges 1 is provided so as to be movable in a predetermined section in the insertion / ejection direction (hereinafter referred to as the front-back direction) by a configuration described later. I have. A traverse unit 19 is disposed further in the depth direction of the stocker 2, and when the stocker 2 is at a predetermined standby storage position moved in the depth direction, the specified disk cartridge 1 is pulled out and attached to the traverse unit 19 for reproduction. You can do it.

The stocker 2 is partitioned by a partition plate for storing a plurality of disk cartridges 1 in a stacked manner, and is opened in the cartridge insertion direction. The stockers 2 are protruded from the opening of the front panel 7 at the time of ejection, and are configured to be detachable one by one by holding the stored disk cartridges 1 on both sides.

A method of moving the stocker 2 will be described below with reference to FIGS. 2, 4, 5, and 11. Stocker 2
Are guided on both sides by a stocker angle L5 and a stocker angle R6 fixedly arranged on a mechanical chassis (not shown) fixed to the housing 3. Further, the stocker 2 is transported in the front-rear direction by the stocker rack 4 sliding on the stocker angle L5. The stocker rack 4 constitutes a stocker transfer means for performing a predetermined section movement by driving a reduction gear train using the transport motor 27 as a drive source. Rotation is transmitted from the motor worm gear 30 provided on the output shaft of the transport motor 27 to the worm wheel 31 by changing the axial direction by 90 degrees, and further reduced gears A32 and B3.
3. The stocker rack 4 is moved to a predetermined section by being transmitted to the relay gears A34 and B35. Here, the number of worms of the motor worm gear 30 is four, the lead angle is about 20 degrees, and the torsion angle on the worm wheel 31 side is also about 20 degrees, thereby suppressing the deceleration rate in the worm stage and increasing the transmission efficiency. Thus, the motor worm gear 30 can be rotated from the rear-stage gear side of the driven side.

The movement of the stocker rack 4 causes the engaging pin of the stocker 2 to be simultaneously moved since the stocker rack 4 is engaged.

With such a configuration, the stocker 2 is arranged as shown in FIG.
5 can be transferred from a discharge position where the disc cartridge 1 can be replaced to a standby storage position where an internal change operation is performed as shown in FIG. FIG.
In the standby storage position, the storage device 2 is configured to rotate between a forwardly inclined posture for performing a changer operation inside the playback device and a horizontal posture when the stocker 2 moves by a method described later. When the stocker 2 is tilted forward as shown in FIGS. 5 and 1, the pin behind the stocker 2 is lifted by the inclined cam portion provided on the stocker rack 4, and the front part of the stocker 2 is relatively lowered, and the rear part is lowered. Is raised in reverse.

In the standby storage position, the stocker 2 has been moved further back from the front panel surface to mount the disc cartridge 1 on the traverse unit 19, leaving a gap in the opening. At this time, slide panel 8
When the user opens the disk cartridge and looks into the disk cartridge, the user actually looks down at the apparatus from above, but if the stocker 2 is tilted forward, the back label of the upper disk cartridge 1 is difficult to see. easy.

In FIG. 11, the stocker rack 4 is moved by a predetermined amount by driving the stocker transfer means, and the rear back label surface of the stored disk cartridge 1 is located near the rear surface of the slide panel 8 for shielding the front panel 7. Has been transported to In this state, the gap in the front-rear direction between the opening of the front panel 7 and the stocker 2 disappears,
It is configured to be less susceptible to entry of foreign matter.

By opening the slide panel 8, the back label surface of the disk cartridge 1 can be directly viewed. By providing a transparent or translucent portion at a predetermined portion of the slide panel, the back label surface of the disc cartridge 1 can be confirmed even in a shielded state.

Next, the operation of the stocker 2 by operating the slide panel 8 will be described.

FIG. 1 shows the posture and position of the stocker 2 in the reproducing state of the apparatus. The stocker 2 takes a forward leaning posture at the standby storage position moved from the front panel to the back. At this time, the slide panel 8 is in a state of closing the front panel 7,
Since the operation buttons and the display unit on the surface of the slide panel 8 are connected by the close contacts 10a and 10b, various operations for reproduction are possible. Here, when the slide panel 8 starts to be opened, the closed contacts 10a, 10a
b is electrically disconnected from the slide panel 8 because the connection is released.
The opening start of is detected. At this point, the change operation for replacing the disk cartridge 1 inside the apparatus by the operation button or the like is prohibited.

In response to the detection of the opening, the stocker transporting means for driving the stocker 2 in the front-rear direction starts to operate. As shown in FIG. 5, the stocker 2 is first returned from the forward tilted posture to the horizontal posture, and then moved forward. And the rear back label surface of the disc cartridge 1 shown in FIG. 11 is moved to a position near the front panel 7. This position is a preparation position for ejection, and as described above, the label of the disk cartridge 1 can be easily checked, and entry of foreign matter into the opening can be prevented.

When the slide panel is further opened and the disk cartridge 1 becomes wide enough to insert the disk cartridge, a light click portion is provided on the sliding portion so that the structure is easily stopped once. At this open position, if there is an empty space in the insertion portion of the stocker 2, the disc cartridge 1 can be additionally inserted at this time. There is no protrusion of the disk cartridge 1 from the front panel 7, and the front surface is aligned after mounting, so that it is easy to check the mounting.

Next, when the slide panel 8 is further opened to a completely opened state, the panel open completion sensor 11 is detected, and upon receiving this detection, the stocker 2 is re-opened.
The stocker transfer means for driving the stocker 2 in the front-rear direction starts operating in the forward direction, and the disc cartridge 1 of the stocker 2 is ejected from the front panel 7 as shown in FIG. No need to press.
At this position, the removal and replacement of the disk cartridge 1 can be performed freely.

When the disk cartridge 1 is inserted into the empty slot, the disk cartridge 1 is inserted into the empty slot until the rear label surface of the rear part is aligned with the partition plate part of the front part of the stocker 2. The lock portion holds the notch portion of the disk cartridge 1. When this stocker 2 is in the discharge position,
By shorting the terminals of the transport motor 27,
By increasing the braking torque of the transport motor 27, the force against the pushing force applied to the stocker 2 can be increased. Therefore, a holding torque against the force of the leaf spring of the chucker 12 can be stably secured when the disc cartridge 1 is mounted in the insertion direction toward the same housing.

When the disc cartridge 1 has been replaced and the user wants to store it again, the user presses the open / close button 9 on the front panel 7 or pushes the stocker 2 in, so that the stocker transporting means drives the stocker 2 by rotating in the reverse direction to the ejection. By moving it in the depth direction, the state shown in FIG. 1 can be restored. Here, when the stocker 2 is directly pushed in, a rotational force is generated between the stocker rack 4 and the relay gear B35, and the rotation is transmitted from the rear gear side of the gear train of the stocker transfer means to the transport motor 27 of the drive source after deceleration. Is done. When it is detected that the stocker 2 has been moved from the specified discharge position, the energization of the motor 27 is started and the motor 27 is electrically driven.

When the stocker 2 is driven from the inside of the housing in the discharge direction, if there is an obstacle that cannot project to the predetermined discharge position, the power supply in the discharge direction is stopped and the transport motor 27 is stopped.
By opening the terminal between the two terminals, destruction of the gear can be prevented. When the terminals of the transport motor 27 are open at both ends, the braking torque of the transport motor 27 is reduced, so that the pushing load of the stocker 2 can be reduced, and the pressure applied to each drive gear, especially the subsequent relay gear B35 can be reduced. .

In the state shown in FIG. 11, when the slide panel 8 is returned from the opened state to the closed state, the close contacts 10a and 10b are connected again. When the transfer means moves the stocker 2 in the depth direction to bring it back to the state shown in FIG. 1, it is possible to quickly return to the standby storage state during reproduction. When returning to this state, various operations such as a change operation using the operation buttons and display can be performed.

FIG. 10 shows the flow of control at this time. Also, in FIG. 10, when the open / close button 9 is first pressed, if the closed contacts 10a and 10b are detected, the fact that the slide panel 8 is not opened is displayed on a predetermined display section, and the opening of the slide panel 8 is performed. Will be encouraged.

Further, in the above embodiment, the steady standby state when the stocker 2 is reproduced is the state shown in FIG. 1 located at the back, but if the position shown in FIG. Alternatively, by providing a translucent transmissive portion, the spine label of the disk cartridge 1 can always be easily visually recognized, and the chance of foreign matter entering the opening can be further reduced. However, the changer operation time for replacing the reproduction disk cartridge 1 inside the apparatus is longer than that in the above-described embodiment. These two embodiments can be selected according to the user's preference by setting the control means without changing the configuration of the mechanism.

In the above embodiment, when the slide panel 8 is completely opened, the stocker transferring means starts transferring the stocker 2 immediately, but the detection by the panel open completion sensor 11 is prohibited. The discharge operation may be performed with the open / close button 9 only when the discharge command is permitted.

Next, a description will be given of the regulation of dropping of the disk cartridge stored in the stocker 2 in the front-back direction.

In FIG. 2, on the left side of the stocker 2, a cartridge regulating arm 29 for regulating the movement of the disk cartridge 1 in the front-rear direction is provided. The cartridge regulating arm 29 is rotatably supported in a U-shape in the vertical direction of the stocker 2 in the vicinity of the center. It has a configuration with a restricting part that contacts. When the stocker 2 is at the standby storage position inside the apparatus, the cartridge regulating arm 29 regulates the rear portion of the disc cartridge 1 to prevent the disc cartridge 1 from dropping forward.

In this state, careless insertion of a new disk cartridge is also prevented. Next, when the stocker 2 is transferred to the near side by the stocker transfer means and transferred to the position shown in FIG. 11 or FIG. 4, the cartridge regulating arm 29 is turned by a cam (not shown) provided by a cam provided on the mechanical chassis. When the disc cartridge 1 is newly inserted into the insertion slot of the stocker 2, the disc cartridge 1 can be prevented from being pushed too far and falling off in the depth direction when the disc cartridge 1 is newly installed in the insertion slot of the stocker 2.

Next, the traverse unit 19 will be described. In FIGS. 2, 6 and 9, positioning pins for positioning the disk cartridge 1 are implanted in the traverse unit 19 (playing means), and a spindle motor 23 for rotating the disk is mounted.

The chucker 12 holds the disc cartridge 1 and is integrally transported to the traverse unit 19 by the carrier 13 provided in the cartridge transfer means. Four guide pins are provided on both side surfaces of the chucker 12, and five chuckers 12 engage with guide grooves 2 a provided on both side surfaces of the stocker 2, respectively, to maintain the height of the disk cartridge 1 and guide the conveyance. It is carried out.

The stacking interval between the first and second disk cartridges 1 is such that the rear stacking interval L2 is wider than the front stacking interval L1. The stacking interval between the fourth and fifth stages is such that the rear stacking interval L4 is wider than the front stacking interval L3. The stacking interval between the second and third tiers and the stacking interval between the third and fourth tiers are the same between the front and the rear, and in the horizontal state shown in FIG. They are almost parallel.

As described above, by reducing the stacking distance in front, even when the stocker 2 is discharged out of the housing 3, the front panel 7 and the disk cartridge 1 do not interfere with each other, and the design of the front panel 7 can be prevented. Degree of freedom can be increased. Also, by increasing the rear stacking interval, the disc cartridge 1 can be moved to the traverse unit 19.
When pulled out to the side, a gap between the upper and lower disk cartridges 1 and the chucker 12 can be secured.

Next, the holder 17 will be described. The rear end of the holder 17 is rotatably supported by the rear end of the traverse unit 19, and its rotation fulcrum 19a is located at the third stage of the stocker 2 inclined as shown in FIG.
Is provided on a substantially extension of. When the fifth-stage disc cartridge 1 is selected, the holder 17 forms a maximum angle with respect to the traverse unit 19 and maintains a posture substantially parallel to the housing 3.

In addition, even with a reduction gear mechanism using a worm, destruction can be prevented by a simple drive mechanism having a configuration that does not require a double lever structure or the like. Therefore, even if there is an obstacle that cannot project to the predetermined discharge position, the gear can be prevented from being broken.
