Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electronic apparatus in which a case such as a magazine containing a plurality of discs or a package containing recording media other than discs is loaded, and particularly when the case is ejected from a loading section. The present invention relates to an electronic device that prevents a case from popping out more than necessary.
[0002]
[Prior art]
FIG. 5 is a perspective view showing a part of a disk changer as an example of a conventional electronic apparatus loaded with a recording medium.
[0003]
In the disk changer 1 shown in FIG. 5, a discharge mechanism 3 is provided on the ceiling surface 2 </ b> A of the mechanism chassis 2. The discharge mechanism 3 is provided with a discharge lever 4. The discharge lever 4 is supported on the ceiling surface 2A so as to reciprocate in the (i)-(ii) direction, and is urged in the (i) direction by springs 5 and 5.
[0004]
A magazine M storing a plurality of disks (for example, compact disks) D is loaded into a magazine loading section B in the disk changer 1. At this time, the upper end in the insertion direction of the magazine M hits the bent portion 4a that serves as the pressing portion of the discharge lever 4, and the discharge lever 4 opposes the urging force of the springs 5 and 5 by the force of pressing the magazine M by hand. ii) The magazine M is moved in the direction, and the magazine M is locked by the lock mechanism 6 provided on the bottom surface 2C of the mechanism chassis 2 at the end of the movement.
[0005]
When the magazine M is discharged, if the lock mechanism 6 is unlocked, the discharge lever 4 is forcibly moved in the direction (i) by the biasing force of the springs 5 and 5. At this time, the magazine M is pushed by the bent portion 4a of the discharge lever 4 and discharged in the direction (i).
[0006]
Here, when the discharge lever 4 is driven in the direction (i) with a certain amount of force by the springs 5 and 5, the magazine M may jump out of the magazine loading portion B of the disc changer 1 and fall.
[0007]
Therefore, conventionally, for example, a braking member 7 made of a leaf spring or the like inserted into the mechanism chassis 2 from the ceiling surface 2A of the mechanism chassis 2 of the disk changer 1 is provided. When the magazine M moves in the direction (i), the braking member 7 is given a resistance force by the tip of the magazine M repressing the upper surface of the magazine M, so that the brake member 7 jumps out from the magazine loading portion B more than necessary. I try to prevent it.
[0008]
[Problems to be solved by the invention]
However, in the conventional discharge mechanism 3, when the magazine M is located in the magazine loading portion B, the elastic pressing force is always applied to the magazine M from the braking member 7. Therefore, when the magazine M is loaded, both the biasing force of the springs 5 and 5 and the elastic pressing force of the braking member 7 act as insertion resistance on the magazine M. The resistance of becomes very large. Further, since the braking member 7 and the magazine M continue to slide when the magazine M is inserted, not only the sliding resistance is large, but the outer surface of the magazine M may be damaged by the sliding.
[0009]
Further, when the magazine M is discharged, the sliding resistance force between the braking member 7 and the magazine M continues to act. Therefore, when the force of the springs 5 and 5 is weak, the magazine M is reliably pushed by the discharge lever 4. There are times when it cannot be put out.
[0010]
That is, if the elastic force of the braking member 7 and the elastic force of the springs 5 and 5 are not well balanced and set, the magazine M cannot be pushed out with the discharge lever 4 as described above, or the magazine M is inserted. This causes inconveniences such as extremely large resistance. However, the installation posture (mounting angle) of the disc changer 1 and the number of discs stored in the magazine vary for each user, and the braking formed by a leaf spring or the like according to these various usage environments. It is extremely difficult to finely adjust the elastic force of the member 7 and maintain the appropriate elastic force so as not to change for a long time.
[0011]
The present invention is for solving the above-described conventional problems, and by using the operation of a discharge member that pushes out a case such as a magazine, the insertion resistance is extremely increased by giving the case a resistance when protruding. It is an object of the present invention to provide an electronic device loaded with a recording medium that can prevent the case from popping out without disturbing the discharging operation.
[0012]
[Means for Solving the Problems]
The present invention relates to an electronic device in which a case in which a recording medium is stored is inserted and installed in the loading unit from the insertion port.
The loading portion is formed with a discharge member that is movable toward the insertion port and pushes the case toward the insertion port during the movement, and a guide portion that guides the discharge member toward the insertion port. And a spring member that biases the discharge member toward the insertion port,
The discharge member is provided with a pressing portion that is located on the back side of the device and applies a discharge force to the case, and at least one of the discharge member and the wall portion is caused by a biasing force of the spring member. An inclined portion that guides the insertion port side of the discharge member in a direction away from the case, and an insertion port side of the discharge member that is positioned between the pressing portion and the inclined portion and is separated from the case by the inclined portion. A protrusion for partially contacting the discharge member and the wall,
When the discharge member moves toward the insertion port and a part of the case protrudes from the insertion port, the discharge member is guided in the direction away from the case by the inclined portion, and the discharge by the protrusion. When the member and the wall portion come into contact with each other, a rotational force with the projection serving as a fulcrum acts on the discharge member, and a resistance force that opposes the discharge force is applied to the case from the pressing portion. It is a feature.
[0013]
In this electronic apparatus, when a part of the case pushed by the discharge member protrudes from the insertion port, the discharge member and the wall part come into contact with each other through the protrusion, and further, rotational force acts on the discharge member. A resistance force acts on the case from the discharge member. Accordingly, the case receives a large resistance force in the latter half of the discharging operation, smoothly protrudes from the insertion port, and prevents the projection from protruding from the insertion port. Further, the resistance force when the case is inserted into the loading portion does not become excessive.
[0014]
Further, the pressing portion provided on the discharging member is inclined with respect to the moving direction of the discharging member, and the component force of the urging force of the spring member is transferred from the pressing portion to the case toward the bottom of the loading portion. What acts as pressing force to press is preferable.
[0015]
In this structure, since the moving force of the discharge member in the discharge direction acts as a resistance force on the case, the resistance force applied to the case can be increased.
[0016]
The recording medium loaded in the electronic apparatus of the present invention is a compact disc (CD), a digital versatile disc (DVD), a mini disc (MD), various optical discs such as a CD-ROM, a magnetic disc, etc. One or a plurality of these discs are stored in the case. For example, in the case of a disc changer, a plurality of CDs are stored in a case called a magazine. In the case of MD, a cartridge in which one magneto-optical disk is accommodated corresponds to the case of the present invention. Alternatively, a recording medium such as a memory may be stored in the case.

As shown in FIG. 1, the disk changer 11 has a housing 12 as a mechanism chassis housed in an exterior case (not shown). The housing 12 is loaded with a magazine M which is an example of a case storing a disk as a recording medium. An insertion port 12D through which the magazine M enters and exits is opened in the housing 12, and a magazine loading portion B in which the magazine M inserted from the insertion port 12D is loaded is provided in the housing 12. Yes. A front surface of the exterior case in which the housing 12 is housed is a decorative panel, and an insertion port leading to the insertion port 12D is formed on the decorative panel.
[0019]
A plurality of discs are housed in the magazine M so that they can be drawn out, and the entrance is indicated by Ma. As shown in FIG. 1, with the magazine M loaded in the magazine loading portion B, the entrance / exit Ma is directed to the right side in the figure in the housing 12.
[0020]
As shown in FIGS. 2 and 3, a pressed portion M3 protruding upward from the upper surface M1 is formed at the tip of the upper surface M1 of the magazine M in the (ii) direction. A discharge member 14 to be described later hits the pressed portion M3.
[0021]
The right part of the housing 12 in FIG. The disk drive unit E is provided with a disk drive unit that moves up and down (not shown). When a command operation for selecting a desired disk is performed with the magazine M loaded in the magazine loading section B, the drive unit is moved up and down by the disk drive section E, and any disk D in the magazine M is selected. Is done. When the drive unit stops at a position where one of the disks D is selected, the disk (for example, a compact disk having a diameter of 12 cm) D is pulled out from the entrance / exit Ma of the magazine M and held in the drive unit, and the disk D is driven to rotate. Thus, the reproducing operation is performed by the optical head.
[0022]
On the ceiling surface 12A of the housing 12, a pair of openings 12b and 12b extending in the (i)-(ii) direction, which is the moving direction for entering and exiting the magazine M, are formed. In the wall portion 12A1 between the opening 12b and the opening 12b, a rectangular hole guide portion 12d extending in the moving direction and a guide elongated hole 12e which is also an oblong hole extending in the moving direction are formed. . A long plate-like discharge member 14 that moves in the (i)-(ii) direction along the movement direction of the magazine M is provided below the wall portion 12A1.
[0023]
A guide piece 14a that is bent upward from the main body of the discharge member 14 is integrally formed at one end of the discharge member 14 in the discharge direction (direction (i)) facing the insertion port 12D. An inclined portion 14b is formed in the bent portion of the guide piece 14a.
[0024]
Further, the discharge member 14 is provided with a guide shaft 14c on the upper surface thereof in the back side in the housing 12 relative to the guide piece 14a, and the guide shaft 14c is guided by being inserted into the guide long hole 12e. . The length of the guide shaft 14c is longer than the plate thickness of the wall portion 12A1, and a retaining portion 14c1 for preventing the guide shaft 14c from coming out downward from the inside of the guide elongated hole 12e is provided at the upper end thereof. Accordingly, the discharge member 14 can move up and down in the magazine loading portion B by a dimensional difference between the length of the guide shaft 14c and the thickness of the wall portion 12A1.
[0025]
When the guide piece 14a is guided by the guide portion 12d and the guide shaft 14c is guided by the guide elongated hole 12e, the discharge member 14 slides in the (i)-(ii) direction at the lower portion of the wall portion 12A1. It is free. Further, at the other end of the discharge member 14 in the (ii) direction, there is a pressing portion 14d bent from the main body of the discharge member 14 and a facing portion 14e facing the insertion side surface of the magazine M at the tip. It is integrally formed.
[0026]
In the middle of the guide piece 14a and the pressing portion 14d, projecting portions 14g and 14g projecting upward are integrally raised on the surface of the discharge member 14 with a facing interval wider than the width of the guide portion 12d. Is formed. As shown in FIG. 2, when the magazine M is loaded in the loading section B and the discharge member 14 is in a fully loaded state, and as shown in FIG. 3, the discharge member 14 is moved in the (i) direction. In the middle of the movement, the protrusion 14g is positioned below the wall 12A1, and as shown in FIG. 4, almost simultaneously with the discharge member 14 moving in the direction (i) and reaching the stop state. The protrusions 14g and 14g come into contact with the lower surface of the wall portion 12A1 on both sides of the guide portion 12d to form a contact point Q.
[0027]
As shown in FIG. 2, a notch 12g is formed in the rear wall of the housing 12 in the (ii) direction, and the discharge member 14 is most moved in the direction (ii) in the drawing. When the state is reached, the pressing portion 14d and the facing portion 14e enter the notch 12g.
[0028]
The discharge member 14 is integrally formed with spring hooking pieces 14 f and 14 f extending in both directions, and extends to the openings 12 b and 12 b of the housing 12. Spring ceilings 12f and 12f are formed on the ceiling surface 12A of the housing 12, and a pair of tension coil springs (spring members) are provided as spring members between the spring hooks 14f and 14f and the spring hooks 12f and 12f. ) 15,15. Due to the elastic force of the tension coil springs 15, 15, an urging force Fs is always applied to the discharge member 14 in the direction (i), which is the discharge direction.
[0029]
In a state where the magazine M is inserted into the magazine loading portion B, the discharge member 14 is positioned between the lower surface of the wall portion 12A1 of the housing 12 and the upper surface M1 of the magazine M, but the wall portion 12A1. Between the lower surface and the upper surface M <b> 1, there is provided a movement allowance S that allows the discharging member 14 to rotate.
[0030]
As shown in FIG. 1, in the magazine loading section B of the magazine M, a lock member 16 is provided on the bottom surface 12 </ b> C of the housing 12, and this lock member 16 is attached so as to protrude in the ceiling direction by the urging force of the compression spring 17. It is energized. On the other hand, on the lower surface of the magazine M, a lock groove M2 that fits into the lock member 16 is formed.
[0031]
The disk changer 11 is provided with a lock release mechanism for forcibly moving the lock member 16 downward in the figure against the urging force of the compression spring 17 so that the magazine M can be unlocked. (Not shown).
[0032]
Hereinafter, magazine insertion and ejection operations in the disk changer will be described.
[0033]
When waiting for loading of the magazine M, the discharge member 14 is moved to the insertion port 12D side by the urging force Fs of the tension coil springs 15 and 15. When the magazine M is inserted from the insertion port 12D, the pressed portion M3 hits the pressing portion 14d of the discharge member 14. When the magazine M is inserted in the direction (ii) toward the magazine loading section B, the discharge member 14 is moved in the (ii) direction against the urging force Fs of the tension coil springs 15 and 15.
[0034]
At this time, since the pressing portion 14d inclined by the pressed portion M3 is pressed in the (ii) direction, the discharge member 14 has the pressing portion 14d with the contact portion between the guide piece 14a and the wall portion 12A1 as a fulcrum. It is pushed in the direction (ii) together with the magazine M while tilting so that the side is lifted.
[0035]
As shown in FIG. 2, when the magazine M is pushed to the end in the direction (ii), the lock member 16 shown in FIG. 1 is fitted into the lock groove M2 of the magazine M, and the magazine M is inserted into the magazine loading portion. The loaded state is locked to B. In this loading completion state, the end portion on the (ii) side of the discharge member 14 contacts the lower surface of the wall portion 12A1 in a state where the pressed portion M3 hits the pressing portion 14d. Therefore, the pressed portion M3 is pressed obliquely downward by the inclined pressing portion 14d, and the magazine M is pressed against the bottom surface 12C of the housing 12 by the component force F1z of the pressing force F1. Therefore, the lock member 16 can be reliably fitted to the bottom surface of the magazine M.
[0036]
Further, when the discharge member 14 is pushed in the (ii) direction together with the magazine M, the protrusions 14g and 14g are separated from the wall 12A1 downward in the figure, so that the protrusions 14g and 14g are formed on the wall 12A1. There is no sliding, and the sliding frictional force does not act as a resistance force. Therefore, the insertion load can be reduced when the magazine M is inserted.
[0037]
Next, when an operation button for ejecting the magazine M is operated, the lock member 16 is retracted downward from the bottom surface 12C of the housing 12 by a lock release mechanism (not shown), and the lock member 16 locks the magazine M. The magazine M is released from the groove M2 and unlocked.
[0038]
Simultaneously with the unlocking, the urging force Fs of the tension coil springs 15, 15 causes the discharge member 14 to start moving in the (i) direction, and the magazine M is pushed out by the pressing portion 14 d of the discharge member 14. At this time, since the component force of the discharge force applied to the pressed portion M3 from the inclined pressing portion 14d is applied toward the bottom surface 12C, the frictional force between the magazine M and the bottom surface 12C is increased, and the magazine M is applied. On the other hand, a resistance force against the protrusion can be applied.
[0039]
Then, as shown in FIG. 4, when the discharge member 14 moves to the movement end in the direction (i), a part of the magazine M protrudes from the insertion port 12D. At this time, the inclined portion 14b provided on the guide piece 14a of the discharge member 14 hits the end 12d1 on the insertion port side of the guide portion 12d, and the inclined portion 14b is moved by the urging force Fs from the tension coil spring 15. The guide piece 14a is slid along the sliding point P at the upper end of the end portion 12d1, and is guided away from the wall portion 12A1.
[0040]
By the guide operation, the protrusions 14g and 14g provided on the discharge member 14 come into contact with the lower surface of the wall portion 12A1 to form the contact point Q. When the guide piece 14a is lifted by the inclined portion 14b, the discharge member 14 rotates counterclockwise with the contact point Q as a fulcrum. At this time, the urging force Fs of the tension coil spring 15 acts on the lower side of the drawing with respect to the contact point Q, so that the discharge member 14 is further rotated counterclockwise by the urging force Fs. That is, the discharge member 14 is rotated counterclockwise by both the lifting guide force by the inclined portion 14b and the urging force Fs.
[0041]
Therefore, when a part of the magazine M protrudes from the insertion port 12D, a large force acts on the magazine M in the direction of the bottom surface 12C, and a large resistance force that opposes the protruding output is given to the magazine M. it can. Therefore, when a part of the magazine M protrudes from the insertion slot 12D, it is possible to prevent the magazine M from jumping out of the insertion slot 12D with its inertial force.
[0042]
Further, when the magazine M is extracted from the magazine loading section B, the discharge member 14 waits for the insertion of the next magazine M in a posture that is most rotated counterclockwise with the sliding point P as a fulcrum.
[0043]
In addition to the embodiment described above, the inclined portion 14b is formed on the end 12d1 side, and the guide piece 14a moved to the end in the direction (i) is guided upward by the inclined portion. You can also
[0044]
Further, the protrusions 14g and 14g may be formed not on the discharge member 14 side but on the portion indicated by the contact point Q on the lower surface of the wall portion 12A1. Or you may form the protrusion which mutually opposes to both the discharge member 14 and wall part 12 A1.
[0045]
【The invention's effect】
As described above, in the present invention, when the discharge member is moved by the force of the spring member and the case such as a magazine is pushed out, at the final time, the case protrudes extremely from the insertion port or falls out of the insertion port. Can be prevented.
[0046]
Further, since both the discharging force and the resistance force for preventing the pop-up are applied to the case only by the operation of the discharging member, the structure is simple and the case discharging operation can be performed smoothly.
