Description

Disk holding device

One of the oldest technologies of disk loading devices is to put the disc on the tray and move it to the destination while playing the prepared tray.

There are two types of disc loading methods by the tray: a tray driving unit for loading / unloading discs, and a pick-up driving unit. Each of the driving units is constructed in an interlocking relationship in which the position of the disc is controlled according to the selection. It is known that there is not a large malfunction such as the deviation from the path even when it is removed, and the damage or skewing of the disk is mechanically managed by the tray.

However, in order to load / unload the disc, the operation of the tray must precede the operation of the tray. In case of loading the disc, the tray is taken out after the tray is taken out, then the tray is loaded again, And thus unnecessary operations are repeated.

The disc ejecting structure disclosed in U.S. Patent No. 5,136,570 has a structure in which a transverse roller 2 is provided in the interior of the interior disc housing 1 as shown in Figs. 1 and 2, A plurality of detecting elements 4 (4a) for sensing the position are accommodated from a disk having a large radius to a disk having a small radius.

The apparatus compensates for the disadvantages of using a disk loading apparatus that uses a tray for loading / unloading a disk.

That is, when the disc 3 is pushed into the prepared disc port 5 without depending on a member such as a tray, the disc 3 is moved to the destination and landed on the turntable 6 as it is.

Even in the case of unloading, the ejection of the disk is advanced by the ejector of the disk guide mechanism part 7, and the disk is ejected by the rotational friction of the transverse roller 2 at the next time.

However, this device is adapted to utilize the frictional force of the transporter 2 at any time in the loading / unloading mode of transporting the disk 3, so that the disk 3 ) There are disadvantages.

Another disk loading apparatus of U.S. Patent No. 5,255,255 is similar to the direct loading system in which the disk 3 is pushed into the disk port 5, which is a feature of the roller system, and the disk loading method.

4, the disk loading rollers 8 and 8a have a predetermined moving area from the inside of the disk housing 1 and are dependent on the position of the disk 3, The main part includes left and right rollers 8 and 8a which come into close contact with the side surface of the disc 3 and guide rails 9 for guiding the movement of the rollers 8 and 8a. Left and right symmetrical drive gear groups 11 and 11a meshing with the plurality of gears for turning the rollers 8 and 8a by the rotational force of the loading motor 10, And controls the loading motor 10 by detecting the position.

The disc loading in the apparatus detects the position of the disc 3 when the disc 3 is inserted and transmits the detected position to the control unit. The control unit controls the loading motor 10 to determine the rotating direction of the rollers 8 and 8a, The loading motor 10 is stopped in the previous step.

When the driving signal is inputted to the loading motor 10, the loading motor is rotated in the direction opposite to the loading direction, and the interlocking gears are widened in both directions so that the rollers 8 and 8a are connected to the rails 9 The disc 3 is released by the rotational friction of the rollers 9 and 9a.

Here, the positions of the rollers 8 and 8a vary depending on the size and position of the disc 3 along the rails 9 and 9a.

Therefore, even in this case, it is possible to load the disc 3 without any other transportation mechanism necessary for loading the disc, but there is a disadvantage that the wear of the roller is repeatedly used for repeated use of the disc.

The disk loading device shown in FIGS. 5 and 6 is a special type of holding devices 20L and 20R having guide grooves 22L and 22R for holding both sides of the disk 3 to load the disk, .

The apparatus is mounted on loading plates 23L and 23R which slide through the holding devices 20L and 20R without moving the disc by surface contact of a friction member such as a roller in conveying the disc 3, Is moved through the guide grooves 22L and 22R. This prevents the disc from being damaged due to damage to the disc or from being unable to convey the disc due to wear of the roller.

The apparatus provides the disk 3 with a certain degree of contact force with the disk through the holder without giving a special friction force to the disk 3 so that the disk 3 is precisely positioned so that the disk does not slip or flow in the loading plates 23L, And how to hold a disc below or above the specification that the disc size is out of the disc fixing area by the holder whose receiving area is set to the specified size There is a problem.

The main part of the holding device 24L includes a movable holder 25 mounted on the moving plates 23L and 23R and moving together with the movable holder 25, A disk guide member 26 for constructing a rotation point on the movable holder 25 and the disk guide member 26L, an elastic member 27 for elastically connecting the movable holder 25 and the disk guide member 26, And a regulator track 28 formed on the base plate 21 for regulating the movement of the member 26. [

The movable holder 25 is formed with a boss 29 to be rotatably fixed to the moving plate 23L so as to be coupled to the moving plate 23L by the pin 30 and to move the disc side There is provided a disk guiding groove 31 in which an inner curvature serving as a contact surface is formed in accordance with the outer peripheral curvature of the disk and a tuck 32 for fixing the elastic member 27 is formed at one end.

The disk guide member 26 is rotatably fixed to the moving plate 23L with a pin 34 by projecting a downward-directed rod pin 33 guided by the regulator track 28 on the base plate 21 side, A barrier 35 is formed at one end to contact the movable holder 25 so as to limit its movement and an end portion in a direction perpendicular to the barrier 35 about the fixed point of the pin 34 is in contact with the disk side A roller 36 for guiding the rolling of the disc is installed, and a ring 37 for hanging the elastic member 27 is formed around the roller 36.

The center of the roller 36 is attached to the movable holder 25 in a position aligned with the extension groove 31 of the movable holder 25 in an aligned manner.

The elastic member 27 is connected to the jaw 32 of the movable holder 25 and the ring 37 of the disk guide member 26 and is installed to pull the two members inward.

The use of a compression coil spring is suitable for the elastic member 27.

The regulator track 28 is divided into one track 38 in the inward direction and two tracks 39 in the outward direction to guide the load pin 33 of the disk guide member 26 in accordance with the displacement of the moving plate 23L .

The operation of the disk holding device of the present invention is the same as that of the eleventh to seventeenth through the process of loading / unloading the disk.

Disk loading 1 to loading 4 corresponds to the inserted state of the disk exceeding the prescribed disk size in the eleventh to fourteenth degrees.

The disk holding device 24L in the disk loading 1 presses the side surface of the disk 3 with the pulling force of the elastic member 27 connecting the movable holder 25 and the disk guide member 26 when the disk is inserted The other holder 24R holds the disk 3 in a form to simply guide the disk 3 and the rod pin 33 of the guide member 36 is moved to the other side of the regulator track 24R, To the position capable of advancing in the direction A in Fig. (Fig. 11)

The loading 2 is a state in which the loading plate 23L released along the base plate 21 moves in the direction of the arrow A while the disk 3 is held by the holding device 24L and moves the movable holder 25 to the boss 29 The other side of the movable holder 25 pushes the barrier 35 of the guide member 26 when the combined pin 30 is pushed in the direction B in the center. At this time, the elastic member 27 is elongated so that the connection point on the side of the movable holder 25 and the side of the disk guide member 26 becomes long and the disk side is guided to the guide groove 31 on the side of the movable holder 25, And moves to the loading position while rolling in contact with the roller (36) on the member (26) side. (FIG. 12)

The loading 3 is a disk clamping standby state in which loading of disks by the upward movement of the loading plates 23L and 23R in the loading 2 is completed. At this time, the disk 3 is moved in the direction of the movable holder 25 side guide groove 31 and the guide member The load pin 33 of the guide member 26 is on the space of the regulator track 28 while the flow is prevented by the side roller 36 and the precise centering with the pickup base side is maintained, 23L, respectively. (Fig. 13)

In the loading 4, since the loading plates 23L and 23R are widened to the left and right in the loading 3, the position of the disk guide member 26 side rod pin 33 is released from the regulator track of the base plate 21 side The loading pin 23L moves in the outer C direction due to the movement of the inner one track 38 of the load plate 28 so that the load pin 33 is tangent to the outer two tracks 39 of the regulator track 28 As a result, the movable holder 25 slowly rotates in the direction D about the pin 30 of the boss 29.

In this state, the disc 3 is disengaged from the movable guide holder 25 on the left side and the disc guide groove 31 on the right holder 24R, and is also released from the roller 36 on the guide member 26, thereby releasing the disc holding. (Fig. 14)

In the case where the size of the disk exceeds the prescribed size, the loading pin 3 is divided into loading 3 as shown in the 15th to 17th drawings. In the loading 1, the position of the load pin 33 on the side of the disk guide member 26 is shifted from the base plate 21, Side regulator track 28 so that the loading plate 23L can be moved in the A direction. At this time, the size of the movable holder 25 is small enough to sufficiently accommodate the barrier 35 already on the guide member 26 side. (Fig. 15)

The loading 2 is a state in which the load pin 33 on the side of the guide member 26 is advanced along the two tracks 39 outside the regulator track 28 on the side of the base plate 21 and the disk loading is completed, to be. (Fig. 16)

The loading 3 is a position in which the loading plates 23L and 23R are widened to the left and the left to release the disk holding and the position of the rod member 33 on the side of the guide member 26 is shifted to the position of the regulator track 28 The disc 3 is regulated and positioned in the stopper groove 23H on the other side and the disc 3 is in a free state and is clamped while being down. (Fig. 17)

Disk ejection proceeds in the reverse order of loading.

The disk holding apparatus of the present invention corresponds to the rigid disk holding apparatus having the loading plates 23L and 23R as shown in FIG.

The role of the holding devices 24L and 24R in the presence of the loading plates 23L and 23R is to move the disc 3 through the disc port 5 and to move the disc 3 In a stable state.

Therefore, in the disc loading apparatus having the loading plates 23L, 23R, the holding apparatus guides and loads the disc 3, and at the time of ejecting, the disc is held again and is sent out.

The holding device applied to this type of disk loading device is not adapted to accommodate disks of all sizes and is adapted to hold only prescribed disks.

For example, when the standard disk size is 120 mm, the width of the two side holders is set to about 120 mm, and both sides of the disk 3 are guided to the loading plates 22L and 22R in a holding state.

If the disc size is outside of the standard size, the disc may be poorly held. For example, if the disc size is too small to hold the disc, the disc will flow. If the disc size is too large, disc holding is difficult.

Also, even in the case of a size conforming to the standard, there is a disk flow in the process of loading the loading plates 23L and 23R.

The disc holding apparatus according to the present invention is capable of disc holding with respect to the disc 3 passing through the disc port 5.

The disc holding apparatus of the present invention such as the eleventh guide guides the side surface of the disc 3 in a resilient manner when the disc is loaded.

When the disc 3 passes the disc port 5 on the side of the disc housing 1 and reaches the holding device 24L and the holder 24R, the disc 3 is guided to the guiding groove 31, The side surface of the disc 3 is elastically contacted with the guiding groove 31 of the movable holder 25 so as to push the movable holder 25 in this state and maintain the close contact state.

At this time, the holder 24R located on the other side takes the form of simply guiding the disc 3 through the guide groove 31. [

The pressing force of the side surface of the disk by the holding device 24L suppresses lifting and flowing of the disk and induces the correct movement of the disk. The laminating force of such a disk side surface can be alternatively provided on the left and right sides Do.

For example, the holding device 24L may be configured to hold the disc 24L in a manner that the holding device 24L is not provided and the other side is not provided with the elastic portion, And the inner wall of the groove 31 is structured to have an elasticity.

When the standard disc size is 120 mm in the disc holding apparatus of the present invention, the left / right width of the holding apparatus 24L and the holder 24R needs to be in a range exceeding 120 mm.

This is to provide a proper holding state for a disc not exceeding 120 mm, and if it exceeds 120 mm, the disc side surface can push and push the elastic part laterally when the disc passes, If the width of the holding device 24L and the holder 24R is matched to 120 mm, the loading of the larger size disc can be compensated for.

Thus, the disc holding apparatus of the present invention provides elasticity to the side surface of the disc, thereby catching the flow generated in the disc moving step, and can not hold the other disc due to the disc size defect.

The present invention provides a disc loading apparatus that can vary the storage width of the disc on the side of the holding device in accordance with the actual size of the disc, thereby enlarging the storage area for defective disc size, The pickup centering can be precisely induced after the completion of loading.
