DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cartridge loading device for a recording and reproducing apparatus that records information or reproduces recorded information.

BACKGROUND ART Conventionally, this type of cartridge loading device has a structure as shown in FIGS. 5 and 6, as shown in, for example, Japanese Patent Application Laid-Open No. 58-108056.

When the cassette 50 is inserted into the cassette storage body 51 as shown by arrow V in FIG. 5, the cassette 50 first comes into contact with the back wall of the cassette storage body 51. Furthermore, when the cassette 50 is inserted against the insertion direction component force X of the tension spring 54 shown by the arrow
The cassette storage body 51 is moved downward in the drawing by the component force Y of the tension spring 54 directed toward the spindle 57 as indicated by , and the mounting of the cassette 50 is completed, resulting in the state shown in FIG. 6a. When ejecting the cassette 50,
By pushing the slide plate 55a in the direction of arrow W, the slope view 55a of the slide plate 55 comes into contact with the pin 52 of the cassette storage body 51, and the cassette storage body 51 is moved upward in the figure by the guide plate 53, and finally The cassette storage body 51 is returned to its original position by the component force X of the tension spring 54 in the cassette insertion direction, and the ejection operation of the cassette 50 is completed as shown in FIG. 6b.

Problems to be Solved by the Invention However, with this structure, the cassette 5
6a, the guide hole 53a of the guide plate 53 is configured so that the pin 52 can move upwardly. can be moved upward in the figure, and at that time the cassette 5
If the disk rotating in the cassette 50 comes into contact with the inner wall of the cassette 50, the disk will be damaged. Incidentally, in order to eliminate the influence of vibration or other external forces, it is possible to increase the component force Y of the tension spring 54, but in this case, the impact force when installing the cassette 50 in a predetermined position increases by that amount. Not only does this result in impact noise, but continuous use may also cause damage to the cassette 50. Furthermore, since the cassette 50 is configured to move and eject the cassette storage body 51 by the component force X of the tension spring 54, when inserting the cassette 50, it is inserted against the component force Since the body 51 also has to be moved, there is a problem in that more insertion force than necessary is required.

Therefore, the present invention is intended to protect the disk even if vibrations or other external forces occur during cassette loading, and to provide stable cassette loading/installation.

Means for Solving the Problems The technical means of the present invention for solving the above problems includes a cartridge holder for storing a cartridge, and a pin provided on the side surface of the cartridge holder that is inserted and guided. a substrate provided with a guide groove, a first position movably supported by the substrate and where the cartridge is inserted or ejected along the guide groove of the substrate, and a first position where the cartridge is stored in the cartridge; a loading plate that reciprocates to a second position where the loaded disk is rotatably driven; an eject plate that is held in the first position and that allows the cartridge holder to be moved to the second position when the cartridge is inserted; and a direction in which the cartridge holder is moved to the first position. an eject sub-plate capable of biasing the loading plate; and one end of the loading plate is hooked to the eject sub-plate, and the other end of the eject sub-plate is hooked to the loading plate and the eject sub-plate. a first elastic member that is elastically engaged and causes the eject sub-plate to generate the loading plate biasing force through the engagement; a second elastic member that biases the loading put in a direction in which the cartridge holder is moved to the second position when the cartridge holder is stopped; and a third elastic member that urges the eject plate in the cartridge ejecting direction.

Effect The effect of this technical means is as follows.

That is, when a cartridge is to be attached to the main body of the apparatus, the cartridge is automatically inserted into the cartridge holder in the same manner as in the conventional case. Movement of the cartridge to the second position is via a loading plate biased by a second resilient member separate from the third resilient member biasing the ejector plate to the lowered position. The vertical direction of the cartridge is also controlled via the loading plate. Therefore, it is possible to reduce the urging force of the eject plate, that is, the force required for mounting the cartridge, and to set the force for regulating the vertical direction of the cartridge to a sufficient magnitude.

As a result, even if vibrations or other external forces occur after the cartridge is mounted, the disk will not be damaged as in the conventional case, and a stable and highly reliable cartridge loading device can be provided.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings.

It is a drive means consisting of, for example, an electrically driven solenoid, which restricts the rotation of the lock lever 38 in the direction of arrow I, and is energized when the cartridge 1 moves to the second position, and the rotation drive body 7 stops. The structure is such that the energization is stopped at certain times. The driving means 60 is energized by a detection means such as a micro switch, although it is not shown in the figure.
The current may be applied by detecting the movement of the cartridge 1 or the cartridge holder 8, or the current may be applied by detecting the movement of the loading plate 20. A hole 48 provided in the substrate 40 and a long hole 30 provided in the eject sub-plate 28 allow the lock pawl 39 of the first lock lever 38 to be inserted into the hole 26 of the loading plate 20.

Next, the loading and unloading operations of the cartridge will be explained.

When the cartridge 1 is inserted into the cartridge holder 8 in the direction of arrow A as shown in FIG.
The protrusion 5a of the slider 5 contacts the protrusion 10.
As the cartridge 1 is further inserted, since the insertion of the slider 5 is restricted by the protrusion 10, the shutter 4 begins to move, and the center hole 2 and head insertion hole 3 are opened accordingly. Next, the cartridge 1 comes into contact with the wall 17 of the eject plate 12. Further, when the cartridge 1 is inserted against the biasing force of the third elastic member 18, the eject plate 12 moves in the cartridge insertion direction (arrow A direction) along the guide shaft 41, and finally the cartridge holder 8

When the lock lever 38 is moved to the position shown in FIG.
The locking pin 39 is engaged with the locking pawl 25 of the loading plate 20. Even if vibration or other external force occurs at this time,
The loading plate 20 is locked onto the substrate 40 by the first locking lever 38, and the loading plate 20 itself does not move in the direction of arrow A. Further, the cartridge holder 8 is also prevented from moving in the direction of arrow D by the inclined surface 23b of the guide hole 23 that engages with the pin 9, and unless the loading plate 20 is unlocked, the cartridge holder 8 will not move in the direction of the arrow D. It does not move in the D direction. Therefore, even if vibrations or other external forces occur, the cartridge 1 will not move, and the disk 6 will not come into contact with the inner wall of the cartridge 1 and be damaged. Figure 2a shows the loading plate 8 and eject sub-plate 2 at that time.

To eject the cartridge 1, push the push button 49 in the direction of arrow A against the biasing force of the first elastic member 37, as shown in FIG. Moving. When the ejector sub-plate 28 moves, the second lock lever 32 is rotated in the direction of arrow F so that the lock pin 34 slides on the inclined surface 46a of the lock claw 46 of the base plate 40. When push button 49 is pressed further,
Since the lock pin 34 is disengaged from the inclined surface 46a, the second lock lever 32 is rotated in the direction of arrow E by the elastic member 35 made of a tension spring or the like.
As shown in FIG.

Shown below. As shown in FIG.
2 are respectively locked on the substrate 40, so the biasing force of the first elastic member 37 acts on both of them to try to move them closer to each other. The first elastic member 37 is set to have a larger biasing force than the second elastic member 27. When the push button 49 is pressed and the eject sub-plate 28 is locked by the second lock lever 32, the rotary drive body 7
rotation is stopped. The stop signal to the rotary drive body 7 may be sent, for example, by detecting the movement of the eject sub-plate 28 using a micro switch or the like (not shown). At the same time as the rotation of the rotary drive body 7 completely stops, the power supply to the drive means 60 is stopped, so the first lock lever 38 is rotated in the direction of arrow I by the biasing force of the first elastic member 37.
The lock pin 39 and the lock pawl 25 are disengaged. Then, the restriction on the movement of the loading plate 20 in the direction of arrow A is released, and the loading plate 20 is moved by the urging force of the first elastic member 37 until the wall 24 comes into contact with the protrusion 31 of the eject sub-plate 28. do. At this time, loading plate 2 is attached to pin 9 of cartridge holder 8.
The inclined surface 23a of the guide hole 23 of No. 0 comes into contact with the guide groove 11, and the cartridge holder 8
direction and moves to the first position. Then, the wall 16 of the eject plate 12 disengages from the pin 9, and the eject plate 12 moves in the direction of arrow B due to the urging force of the third elastic member 18 to eject the cartridge 1. At the same time, a pin 19 provided on the eject cart plate 12
The release lever 36 is rotated in the direction of arrow G as shown in FIG. When the release lever 36 is rotated, the second lock lever 32 is rotated in the direction of arrow F, so that the lock pin 34 and the lock pawl 46 are disengaged and the eject sub-plate 28 can be moved in the direction of arrow B. After that, when the cartridge 1 is pulled out from the cartridge holder 8, the shutter 4 is moved again to the center hole 2 as shown in FIG.
The head insertion hole 3 is closed to prevent dust from entering the cartridge 1 from the outside and adhering to the disk 6.

Effects of the Invention As described above, the present invention automatically mounts the cartridge in the main body of the device simply by inserting the cartridge into the cartridge holder, and after mounting, the loading plate that drives the cartridge holder moves the cartridge holder up and down. Since the structure is configured to restrict directional movement, the disk will not come into contact with the inner wall of the cartridge during disk rotation even if vibration or other external force occurs. In addition, the ejection plate and the loading plate are biased by separate elastic members, and the guide hole of the loading plate is inclined so that the pin of the cartridge holder slides along the inclined surface. , the cartridge can be inserted smoothly, and the cartridge will not drop suddenly and be attached to the device body, so there will be no impact noise or damage to the cartridge when it is attached. .

Incidentally, in the present invention, the guide hole of the loading plate is simply inclined. However, for example, the inclination angle of the guide hole may be changed to move the cartridge holder from the first position to an intermediate position between the first position and the second position. The same effect can be obtained by changing the tilt angle to 45 degrees at times, then changing it to 30 degrees when moving to the second position, or by continuously decreasing the tilt angle.
Furthermore, the urging force of the second elastic member when moving and holding the cartridge holder to the second position can be reduced.

It also has the following effects.

That is, in the present invention, one end of the guide hole of the loading plate that drives the cartridge holder and the guide groove of the substrate are made open, so that the cartridge holder can be assembled by simply inserting it from above.

Therefore, according to the present invention, it is possible to provide a loading device that is easy to assemble and has high reliability, and it is also possible to always provide a good disk condition.
