Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for recording and reproducing information on recording and reproducing discs such as records, video discs, and magnetic discs.

When the disk is not in use, it is generally stored in a jacket to prevent the recording surface from coming into direct contact with people's hands or being contaminated with dust or foreign matter. When in use, the jacket is inserted into the device and then pulled out, leaving only the disc. Thereafter, the disk is rotated within the apparatus by appropriate means, and recording and reproduction are performed by the recording and reproducing means. After recording and playback is finished,
The disk is retrieved into the jacket by inserting the previously withdrawn empty jacket into the device and then withdrawing it.

The present invention is directed to a recording/reproducing apparatus using such a jacket, in particular, in order to ensure operation when a disc is automatically taken out and retrieved from the jacket, a jacket is provided on the front surface of the jacket to allow the disc to be taken in and out. The purpose of this invention is to provide a simple and reliable means for expanding a jacket and a means for loading a jacket. That is.

That is, the present invention has an opening on one side, is provided at a predetermined position near a jacket insertion opening into which a jacket containing a recording/reproducing disk is inserted, and is inserted into the opening of the inserted jacket to open the opening. an expanding means for expanding the opening in the thickness direction of the jacket; a jacket loading means that engages with the jacket opening expanded by the expanding means and moves back and forth within the apparatus integrally with the jacket; and a disk holding device that temporarily holds the disk in the jacket inserted into the device and allows the jacket alone to be pulled out, the expanding means being configured separately from the jacket loading means, It is characterized in that it is configured to be able to approach and separate from the jacket loading means, thereby achieving the intended purpose.

An embodiment of the present invention will be described below with reference to the drawings.
An example of the jacket 2 used in the present invention is a first
As shown in the figure, when not in use, a recording/reproducing disc 6 (hereinafter referred to as a disk) is housed inside together with a lid member 4 (hereinafter referred to as a lid). In the figure, these are drawn out in sequence for the sake of explanation. This lid 4
In order to prevent the disk 6 from deviating from the jacket 2, an opening 8 is provided on one side of the jacket 2.
It's in full swing. The lid 4 has elastically deformable arm portions 12 having convex portions 10 at both ends in the width direction, and as only one of the arm portions 12 is shown in FIG. 14. Further, a protrusion 16 is provided at the center of the lid 4, and when not in use, this engages the engagement hole 1 provided approximately on the center line of the jacket 2.
8 and is engaged in a snug manner. Therefore, normally, the lid 4 protects the disk 6 built into the jacket 2 without easily separating from the jacket 2. Moreover, the lid 4 further has a pair of notches 20 symmetrically about the center line in the width direction at the tip of the lid.

For the disk 6 of such a jacket 2,
A recording/reproducing device (hereinafter referred to as a player) 22 has an insertion opening 24 into which the jacket 2 is inserted, and has the following means inside.

(A) Expanding means for expanding the opening 8 of the jacket 2 inserted into the insertion port 24 in the thickness direction of the jacket.

(B) A jacket loading means for reciprocating the jacket 2 inserted into the insertion port 24 into the player 22. The forward movement of the reciprocation is the movement of the jacket 2 in the direction of insertion, and the return movement is the movement of the jacket 2 in the direction of pulling it out from the player 22.

(C) It is provided on the side opposite to the insertion opening 24 of the player 22 (at the back of the player 22), and temporarily holds only the lid 4 and disk 6 of the inserted jacket 2, and then the jacket 2 is pulled out. A lid member (lid) holding means and a disc (disc) holding means which leave the lid 4 and disc 6 at predetermined positions within the player 22. However, if an empty jacket 2 (without a lid or disc) is inserted with the lid 4 and disc 6 remaining inside the player 22, the jacket 2 may not be inserted all the way into the insertion slot 24. At this point, the lid holding means and the disk holding means release the holding of the lid and the disk respectively, the disk and the lid are stored in the jacket, and then the jacket is pulled out, so that the disk 6 and the lid 4 are in the normal position. The jacket 2 is pulled out from the player 22 while it is completely inserted.

(D) A turntable on which the disk 6 is placed and rotates it.

(E) Disc moving means for placing the disc 6 on the turntable or removing it from the turntable.

(F) Recording and reproducing means for recording and reproducing data on and from a rotating disk mounted on a turntable.

The present recording and reproducing apparatus is composed of such means, but since (D) and (E) above have little direct relationship with the present invention, only a brief explanation will be given, and (F) is not directly related to the present invention. Since it is not relevant, I will not provide an explanation about it.

The configuration and operation of each of the above-mentioned means (A), (B), (C), (D), and (E) will be explained below.

(A) Expanding means The expanding means expands the opening 8 of the jacket 2 in the thickness direction of the jacket, and this is done by elastically deforming the opening 8 of the jacket 2. This means is necessary when using the jacket 2 of this embodiment for the following reason. In order for the lid holding means and disk holding means, which will be described later, to hold the lid 4 and the disk 6 during operation, the following steps are required:
Lid 4 and disk 6 from opening 8 of jacket 2
I had to avoid this and partially slip into the jacket to avoid getting hit. for that,
It is necessary to widen the opening 8 of the jacket 2 in the thickness direction. Furthermore, when inserting the jacket 2 without the lid 4 and disk 6 into the device and recovering the disk 6 and lid 4 inside the device into the jacket 2, it is necessary to expand the opening 8 of the jacket 2 in advance. This is because the disk 6 and lid 4 can be recovered safely.

Now, the expanding means 26 in this embodiment is the third
As shown in the figure, a pair of expansion members 3 are provided near the insertion port 24 of the player 22 and are fixed to a shaft 30 that is rotatably supported by a bearing 28.
Consists of 2. The distal end of the expanding member 32 has a wedge-shaped surface 34 with a shape close to a pointed parabola, and is biased by a torsion spring 36 to rotate in the direction of arrow A in FIG. Normally, its rotation is prevented by a jacket loading means 38, which will be described later.

When the jacket 2 is now inserted through the insertion port 24, the opening 8 of the jacket 2 is inserted into the distal end of the expansion member 32 and comes into contact with the wedge-shaped surface 34, as shown in FIG. 4A. When the jacket 2 is further inserted, the opening 8 of the jacket 2 slides on the wedge-shaped surface 38 and expands as shown in FIG. 4B. At this time, the protrusion 16 provided in the center of the lid 4
inevitably disengages from the engagement hole 18 of the jacket 2. Note that the expanding member 32 is located at a position corresponding to the notch 20 of the lid 4 when the jacket 2 with the lid 4 is inserted.
The lid 4 and the expansion member 32 do not come into direct contact. Note that the lid and disk are omitted in FIGS. 4A, B, C, and D.

The opening 8 of the jacket 2 expanded in this manner can engage with holding claws 40, 42 of a jacket loading means 38, which will be described later. Further, the insertion of the jacket 2 is temporarily restricted when the tip of the jacket 2 comes into contact with the jacket loading means 38 while the opening 8 is expanded according to the above-described configuration.

(B) Jacket loading means The jacket loading means 38 reciprocates the jacket 2 inserted through the insertion port 24 within the player 22. As shown in FIG. 3, this means 38 comprises a jacket holding means 44 and a jacket insertion guide means 46. The jacket holding means 44 is normally provided at a position close to the expanding means 26, and receives the opening 8 of the jacket 2 expanded by the expanding means 26, as shown in FIG. 4C. Two pairs of holding claws 40, 42 and a lid 4
and a window 48 through which the disk 6 can pass, guide bearings 50 and 52 provided at both ends, a jacket engagement piece 54 provided approximately in the center, a release member 56 provided on the left side thereof, and a release member 56 provided on the lower right corner. expansion control piece 5
It consists of 8.

When the jacket 2 is inserted, the opening 8 of the jacket 2 is expanded by the expansion means 26 described above, and in the expanded state as shown in FIG. 4B, the tip of the jacket 2 is held against the jacket holding means. This corresponds to the flat part 60 of 44. In this state, expansion means 2
6 escapes as shown in FIG. 4C, the opening 8 of the jacket 2 engages with the holding claws 40, 42 and remains expanded. Further, when the jacket 2 is inserted, the opening 8 of the jacket 2 is expanded by the expansion means 26, but in this process, the jacket engaging piece 54 is inserted as shown in FIG. 4B.
engages with an engagement hole 18 provided in the jacket 2.

The jacket insertion guide means 46 includes a pair of mutually parallel guide rods 62, which are installed so that their axial directions are in the same direction as the insertion direction of the jacket 2.
64, on which the guide bearings 50, 52 of the jacket holding means 44 are slidably held. Therefore, when the jacket 2 is inserted and the opening 8 is expanded by the expanding means 26, the retaining claws 40, 42 and the jacket engaging piece 54
The jacket is inserted into the player 22 while being guided by the jacket insertion guide means 46. In addition,
Normally, the expansion control piece 58 provided on the jacket holding means 44 is in contact with a cam lever 66 fixed to the shaft 30 of the expansion means 26, so that the jacket holding means 44 moves the jacket 2 into the player 22. When moved, the expansion control piece 58 escapes from the cam lever 66 as shown in FIG. In this way, the expansion means 2
6 escapes out of the passage area of the jacket 2 as the jacket 2 is inserted, so it does not come into contact with the jacket 2 as shown in FIG. 4D.

When the jacket 2 moves in the direction of being pulled out from the player 22, the jacket holding means 44
The expansion control piece 58 provided in FIG. 4C hits the cam lever 66 as shown in FIG. 4C, and the expansion means 26
In the order shown in FIG. 4B, that is, the movement is reversed to that at the time of insertion, and is reset to the initial position shown in FIG. 4A.

(C) Lid member (lid) holding means and disk (disc)
Holding means: These two means hold the insertion opening 24 of the player 22.
It is located in the back on the opposite side. As for its function, when the jacket 2 containing the lid 4 and disc 6 is inserted into the insertion opening 24 of the player 22, only the lid 4 and disc 6 are held temporarily. Then, as the jacket 2 is pulled out from the player 22, only the lid 4 and the disc 6 remain inside the player 22. Next, when a jacket without the lid 4 and disc 6 (hereinafter referred to as an empty jacket) is inserted, the lid 4 and disc 6 that had been in the player 22 until that time are released, and the empty jacket 2 is inserted. Inward lid 4 and disk 6
It is possible to recover In addition, the lid 4 and the disk 6
remains in the player 22, the turntable 1 separately provided in the player 22, as described later.
It has a function of allowing only the disk 6 to descend onto the disk 60.

These two means are not directly related to the gist of the present invention, so they will be briefly explained. In FIG. 3, the lid holding means 68 is a shaft 7 fixed to a mechanical board 70.
The disk holding means 126 includes a pair of left and right engaging members 76 and 78 rotatably held at the left and right ends of the mechanical board 70, and a pushing piece 88 formed at the left and right ends of the mechanical board 70. Member 12
8,130 are the constituent elements. Engagement members 76, 7
8 and the pushing piece 88 are located at the center in the thickness direction of the jacket 2 to be inserted, that is, at the same height as the lid 4 and the disk 6 inside the jacket.

The disk holding means 126, as shown in FIG. The swing clamp member 130 is rotatable about a shaft 134. Convex portions 137 and 139 are provided at the tip portions 136 and 138 of both clamp members to face each other. The inserted disk 6 in the jacket 2 is held here so that its outer periphery is sandwiched (7th disk).

9 are rotated in a direction toward each other, and the take 2 is held between the convex portions 137 and 139.

On the other hand, the lid 4, which has been inserted integrally with the jacket 2, will eventually fit between the disc-shaped clamp members 128 and 130 as shown in FIGS. An engagement member 76 is provided in the notch 20,
The tip of 78 is engaged. Note that the engaging member 76,
Stepped portions 104 and 106 are provided at the distal ends of the engaging members 76 and 78 at a height one step lower than the plane of the engaging members 76 and 78, and serve to support the lid 4 from below.

FIG. 8 is a view immediately before moving to the final stage of FIG. 6, showing the notch 20 of the lid 4 and the engaging members 76, 7
8 are in contact with each other, and the lid 4 is advancing while the engaging members 76 and 78 are being pushed away. Of course, at the final stage, already in the state shown in FIG. The engagement between the portion 10 and the recess 14 on the inner surface of the jacket (FIG. 2) has been disengaged.

In this way, the jacket 2 and the lid 4 are disengaged, and the disk 6 is also disengaged from the clamp member 12.
8, 130, so when the jacket 2 is pulled out, the lid 4 and the disc 6 are attached to the player 22.
remain within. When this disk 6 is lowered onto a turntable 160 (described later), the swinging clamp member 1
30 is rotated counterclockwise in FIG. 7 about the shaft 134, and the tip 138 escapes from the lower surface of the disk 6. At this time, the downward movement of the lid 4 is caused by the step portions 10 of the engaging members 76 and 78.
4,106 supports this from below, which prevents it.

(D) Turntable The turntable 160, as shown in FIG. It is located at a certain position outside (below) the jacket passage area when the jacket is inserted. This turntable 160 has the disk 6 placed on it and is rotated at a predetermined rotational speed by a motor (not shown).

(E) Disk moving means Although the drawings and detailed explanation thereof will be omitted since they are not directly related to the gist of the present invention, since the passage area of the jacket 6 and the height of the turntable 160 are different, the jacket is pulled. When the disc 6 that has been pulled out and is held by the disc holding means 126 is gently lowered onto the turntable 160, and when the disc is recovered using an empty jacket, the turntable 160 is
It serves two functions: lifting the disk 6 from above into the passage area of the jacket 2.

As described above, according to the present invention, the opening of the jacket is expanded by the expanding means provided at a predetermined position near the insertion opening, and the jacket loading means maintains the expanded state so that the jacket is integrated with the jacket. engage,
The jacket is inserted into the apparatus by this jacket loading means, and at the same time, the expanding means escapes out of the jacket passage area in conjunction with this insertion operation, so that the jacket is reliably expanded and Since the open state is maintained by a fixed retaining claw included in the jacket loading means,
It does not involve mechanical movements and can perform extremely stable operations.
