Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a disk mounting device for carrying a disk into a player and mounting the disk on the tray, and particularly to a disk having a different diameter. It relates to a possible disk mounting device.

(B) Conventional Technology Among the compact disc players (hereinafter referred to as players) that have become widespread in recent years, the stationary type has a tray that horizontally moves inside and outside the player in order to convey the disc. An example thereof is shown in FIGS. 9 and 10. Tray (1)
Has a circular recess (disk storage part) (2) on its upper surface for storing the disk (D).
Lifters (3), (3), (3) and (3) are immersively provided in the. The diameter of the recess (2) is slightly larger than the diameter of the disk.

The disc (D) is mounted in the player by storing the disc (D) in the recess (2) when the tray is drawn out, and then operating the open / close button or the like arranged on the player. . When the open / close button or the like is operated in this manner, the tray (1) is carried into the player, and the disc (D) is positioned above a predetermined reproduction position. Then, the lifter (3) (3) (3) (3) is immersed by the desired means, and the disc
(D) descends, the disk (D) is placed on the turntable, and the mounting of the disk (D) is completed.

By the way, recently, there is a movement to commercialize a disk having a diameter smaller than that of a normal compact disk. Therefore, it is preferable that the player is compatible with such a small-diameter disk. However, in the device shown in FIGS. 9 and 10 above, the diameter of the recess (2) is naturally larger than the diameter of the small-diameter disk, so such a small-diameter disk is lifted (3) (3) (3) (3).
Even when placed on the disk, the small-diameter disk cannot be correctly centered with respect to the concave portion (2), so that the small-diameter disk cannot be conveyed into the player and correctly placed on the turntable.

In order to solve such a point, for example, an adapter having the same diameter as a normal disk is used, and a small-diameter disk is attached to the central portion of the adapter and then stored in the recess (2). However, in this case, the small-diameter disk had to be reattached to the adapter when the disk was replaced, and a relatively complicated work had to be performed.

In addition, Japanese Utility Model Publication No. 60-16363 (G11B17 / 0)
In the technique disclosed in 8), a step portion for a small-diameter disk is provided in the concave portion of the tray, and the small-diameter disk is positioned by such a step portion. However, in such a technique, after the disk is pulled into the player, The turntable can be applied to those who raise the disc and place the disc, but it is applicable to players who have the turntable fixed and can raise and lower the disc with a lifter as currently commercialized. Can not.

(C) Problems to be Solved by the Invention Therefore, the present invention is capable of positioning a large-diameter disk and a small-diameter disk in a player having a lifter on a tray, and this positioning can be achieved by a simple operation. An object is to provide a disk mounting device.

(D) Means for Solving the Problems In order to solve the problems, the present invention provides (i) a tray that moves between a disk attachment / detachment position pulled out of the player and a disk playback position pulled in the player. A disk mounting device having a disk storage portion for a large-diameter disk arranged on the upper surface of the tray, and at least three lifters arranged so as to be able to be retracted upward from within the disk storage portion. A small-diameter disk having a diameter smaller than that of the disk is lifted, and a positioning means arranged to engage with the opposite peripheral edge to position the disk is provided, and the small-diameter disk is tilted. Can be transported.

(ii) A disk mounting device having a tray that horizontally moves between a disk attachment / detachment position drawn out of the player and a disk reproduction position drawn in the player, and a disk storage section arranged on the upper surface of the tray. In the above, a lifter projecting from the bottom surface of the disk storage portion so as to be retractable, and a plurality of step portions arranged in the disk storage portion and engaging with a plurality of disk peripheral edges having different diameters, respectively, are provided. One peripheral edge is engaged with the corresponding stepped portion and the other peripheral edge is placed on the lifter, so that the disk can be positioned and mounted in the disk storage portion in an oblique state.

(E) Action (i) The large-diameter disk is placed on the lifter and positioned and stored by the inner wall of the disk storage portion. One edge of the small-diameter disk is lifted by a predetermined lifter and the other edge engages with the positioning means, and is thus positioned in the disk storage section in a state of being inclined with respect to the bottom surface of the disk storage section. When the tray is loaded into the player in such a state, the turntable is positioned immediately below the tilted disk, and when the lifter is subsequently retracted, the lifted peripheral edge of the small-diameter disk is lowered, The small disk is placed on the turntable.

(ii) Each disc is positioned in the disc storage portion in such a state that one edge thereof is engaged with the corresponding step portion and the other edge is placed on the lifter so as to be inclined with respect to the bottom surface of the disc storage portion. To be done. After that, when the tray is loaded into the player, the turntable is positioned immediately below the tilted disk, and the lifter is further retracted, so that the peripheral edge of the disk that has been lifted is lowered, and thus the disk is lifted. It is placed on the turntable.

(F) Embodiment One embodiment of the present invention will be described below with reference to the drawings. The same parts as those shown in FIGS. 9 and 10 used in the prior art are designated by the same reference numerals and the description thereof will be omitted.

Two lifters (4) (4), (5) (5), two in the front and two in the rear, project from the recess (2). Of these, the rear lifter (5) (5) is arranged so as to sandwich the notch (6) provided from the center of the tray (1) toward the rear,
Further, on the upper surface thereof, an inclined portion (5
a) (5a) is formed. Further, in front of the notch (6), there is provided a step (7) which is gradually depressed toward the front. The notch (6) avoids a collision between the tray (1) and a turntable (not shown) when the tray (1) is loaded, and a disc surface (not shown) is picked up when the tray (1) is completely loaded. It is arranged so that it can be scanned. When a disc of a normal size is mounted in the player, the disc (D ₁ ) is placed on the lifters (4), (4), (5), (5) as in the conventional technique. This is done by operating the tray open / close button placed in the recessed portion (2) and then arranged on the player.

Next, when mounting a small-diameter disk having a smaller diameter than such a disk in the player, the front peripheral edge of the small-diameter disk (D ₂ ) is brought into contact with the wall portion (7a) of the stepped portion (7) and the rear portion Inclined part (5a) of lifter (5) (5) with rear edge
Place it on (5a) and place the small-diameter disk (D ₂ ) in the recess (2).
Position within. Therefore, the small-diameter disk (D ₂ ) is a recess
(2) It is positioned in the recess (2) in a state of being inclined with respect to the bottom surface. At that time, there is a slight gap of about 1 mm between the front peripheral edge of the small diameter disc (D ₂ ) and the side surfaces of the front lifters (4) (4).

Then, when the tray open / close button provided on the player is operated, the tray (1) is carried into the player, and the turntable enters below the tilted small-diameter disk (D ₂ ) as described above. Incidentally, caused by the slide or the like of the small-diameter disk during such loading (D ₂₎ is or displacement forward of the small-diameter disk (D ₂₎ caused by departing from the stepped portion (7), or small-diameter disk (D ₂₎ The positional deviation in the left-right direction is prevented by the contact between the peripheral edge of the small-diameter disk (D ₂ ) and the front lifters (4) (4). The rearward displacement of the small-diameter disk (D ₂ ) is restricted by the walls of the inclined portions (5a) (5a) of the lifters (5) (5). When the small-diameter disk (D ₂ ) is thus positioned on the turntable, the lifter (4) is driven by a predetermined means, for example, by using a drive of a clamper (not shown) for crimping the disk to the turntable. ) (4), (5), (5) are immersed, and thereby the raised peripheral edge of the small diameter disk (D ₂ ) is lowered, and thus the small diameter disk (D ₂ ) is placed on the turntable. It At this time, substantially at the same time, the clamper presses the upper surface of the small-diameter disk (D ₂ ) toward the turntable, whereby the mounting of the small-diameter disk (D ₂ ) is completed.

The small-diameter disk (D ₂ ) is carried out in the reverse order of the above. That is, when the tray open / close button is operated, the lifters (4), (4), (5) and (5) are projected first and the rear lifter (5) is
(5) lifts the rear edge of the small diameter disk (D ₂ ) and the lifters (4) and (4) regulate the displacement of the small diameter disk (D ₂ ). Then, the tray (1) is pushed out toward the front of the player, and the small diameter disc (D ₂ ) is carried out of the player.

According to the above-described embodiment, a disc having a small diameter can be positioned in the tray without changing the structure of the tray used conventionally to the left, and the mounting operation of the disc to the player can be performed normally. This is exactly the same as the disk mounting operation, so that there is no need to change the disk mounting mechanism. Further, the mounting operation of the small-diameter disc on the tray is very simple because it is only necessary to place the rear portion of the disc on the rear lifter with the front portion of the disc engaged with the step portion.

In this embodiment, if the stepped portion and the inclined portion of the rear lifter are colored, for example, the mounting position of the small diameter disc can be identified so that the operator can perform the small diameter disc mounting work better. be able to. The display means at such a small-diameter disk mounting portion can be changed in color, in addition to in a pattern.

Next, another embodiment of the present invention will be described with reference to FIGS.

The tray (1) has two steps (8) and (9),
Also, from the back side to the top side, the lifter (10) (10) and the protrusion
(11) (11) is protruding. The lifters (10) (10) and the protrusions (11) (11) are formed on the same levers (12) and (12), respectively, and the levers (12) and (12) rotate on the tray (1). It is freely pivoted (13) (13) and is urged clockwise by springs (14) (14). Further, a clamp lever (16) having a clamper (15) at one end is pivotally supported (17) in the player, and the clamp lever (16) has pins (18) (18) on its lower surface. Is projected. The clamp lever (16) is driven and controlled by a control mechanism (not shown).

When a large-diameter disk is mounted on the tray (1), the peripheral edge of the disk (D ₁ ′) is engaged with the outer step (8) as shown in FIGS. 4 and 5. Place the disc on the lifter (10) (10). When a disc (1) having a small diameter is attached to the tray (1), the peripheral edge of the disc (D ₂ ′) is an inner step as shown in FIGS. 6 and 7.
With this disk engaged with (9), lift the disk (10).
(10) Place on top. The discs (D ₁ ′) (D ₂ ′) mounted on the tray (1) as described above are pressed forward against the corresponding step portions (8) and (9) during mounting. As a result, it moves along the walls of the step portions (8) and (9) formed in an arc shape and is always positioned at a fixed position. The tray of the center hole of each disk (D ₁ ′) (D ₂ ′) at this time
The projected shadow on (1) is slightly shifted in the front-rear direction, and is at substantially the same position.

After that, when the open / close button for opening / closing the tray (1) is operated, the tray (1) is pulled into the player, and the turntable (not shown) arranged in the player is positioned almost directly below the disk. (See FIG. 8). When the tray (1) is completely loaded, the clamp lever (16) is rotated counterclockwise, so that the pins (18) and (18) arranged on the lower surface of the clamp lever (16) are projected (11). Press (11) to move the lever (12) (1
Rotate 2) against the bias of springs (14) (14). By such an operation, the lifters (10) (10) descend, and the lifted edge of the large-diameter disk (D ₁ ′) or the small-diameter disk (D ₂ ′) descends, thereby turning the desired disk. It is placed on the table, and at the same time the upper surface is pressed by the clamper (15) to complete the mounting on the turntable. The disk is carried out of the player in the reverse order of the above. That is, the clamp lever (16) is first rotated clockwise, which causes the levers (12) and (12) to move to the springs (14) and (1).
It is rotated clockwise by the force of 4) and lifters (10) (10)
Rises and one end of the disk is lifted. After that tray
(1) is pulled out and the disc is transported to the outside of the player.

(G) Effect of the Invention As described above, according to the disk mounting device of the present invention, it is possible to securely mount several kinds of disks having different diameters in the player with a simple structure, and even if the disks having different diameters are mounted. The mounting work is extremely easy and practically effective. Further, if the lifter on which the disc is placed is provided with an inclined step portion that engages with the small diameter disc, the position regulation of the small diameter disc at the time of mounting becomes reliable, and the positioning accuracy of the small diameter disc with respect to the tray is improved.
