Other mechanisms such as the disk transport mechanism 34A will be described later for convenience of explanation. As shown in FIG. 1 and FIG. 2, the disc reproducing unit 32A and the disc housing unit 33A are in an opposed arrangement relationship, and both can rotate (swing) and can be inclined. Therefore, the angle α at which the disk reproducing unit 32A must rotate is smaller than the angle at which the disk reproducing unit must rotate when the disk housing unit is fixed, and is ± 3 degrees with respect to the horizontal position. Sufficiently, the space 81A required for the disk reproducing unit 32 to rotate is small. Similarly, the angle β at which the disk storage unit 33A must rotate is smaller than the angle at which the disk playback unit is fixed and only the disk storage unit must rotate, and ± 3 degrees with respect to the horizontal position is sufficient. The space 82A required for the rotation of the disk housing unit 33A is small. Moreover, the space 81A
And the space 82A overlap in the Z direction. Therefore, the height of the disc reproducing device 30A is H10, and it is thin.

Since both the disk reproducing unit 32A and the disk accommodating unit 33A rotate, the disk transport path 48A of the disk reproducing unit 32A and the predetermined disk accommodating portion of the disk accommodating unit 33A are aligned. The time required to perform the above operation is shorter than that of a disk reproducing apparatus in which only the disk reproducing unit operates. Thus, the time required from issuing a command to completing the operation according to the command is short.

[Schematic Operation of Disc Reproducing Device 30A]
(FIGS. 4 to 9) Next, the operation of the disk reproducing device 30A having the above configuration will be schematically described. The disc reproducing device 30A is built in the computer device, and usually, based on a command from the computer device, the disc accommodating unit 3A.
An operation is performed in which the disk 11 in the predetermined disk storage unit of 3A is pulled out and played, and the disk 11 that has been played back is returned to the original disk storage unit of the disk storage unit 33A.

In addition, an operation of ejecting the disk 11 in a predetermined disk accommodating portion of the disk accommodating unit 33A to the outside of the disk reproducing device 30A is performed by an operation of the operator. (1) Operation of pulling out and playing back the disk 11 in, for example, the fifth disk storage section 41A-5 of the disk storage unit 33A (FIG. 4): The disk 11 is stored in the disk storage unit 33A. When a command for designating the fifth disk storage section 41A-5 is issued from the computer device, the operation shown in FIG. 4 is performed. In FIG. 4, the holding finger 1
Regarding the roller 31A, the roller 60A and the roller 61A, the black color indicates that the roller 11 hits the periphery of the disk 11,
An outline indicates that it is farther from the disc. This is the same for other figures.

Is rotated, the holding of the disc 11 by the pressing finger 131a is released, and the pushing finger 131c pushes the disc 11 slightly in the Y2 direction from the fifth disc accommodating portion 41-5.

Subsequently, the disk transport mechanism 34A operates, and as shown in FIG.
0A moves and holds the disk 11 pushed out from the fifth disk storage portion 41A-5, and transports the disk 11 in the Y2 direction to a position in the disk reproducing unit 32A.

Subsequently, as shown in FIG. 4 (D), the turntable 37A moves upward and is coupled with the clamper 38A, the disk 11 is clamped on the turntable 37A, and the rollers 61A and 60A are retracted and the disk 11 is retracted.
More away. Thereafter, the disc 11 is reproduced.

When the computer specifies the fifth disk storage section 41A-5, and the disk 11 is present on the disk reproduction unit 32A,
An operation of accommodating the disk 11 in the disk accommodating unit 33A or an operation of ejecting the disk 11 out of the disk reproducing device 30A (these will be described later).
Then, the operation of transporting the disk 11 in the disk storage unit 33A to the disk reproduction unit 32A and reproducing the disk 11 is started.

(2) The disk 11 whose reproduction has been completed is transferred to the original disk storage section 41A of the disk storage unit 33A.
Operation to return to −5 (FIG. 5): The disk 11 that has been reproduced up to that time is a disk pulled out from the second disk accommodating portion 41A-2, and the disk reproducing unit 32A and the disk accommodating unit 33 are (A), FIG.
As shown in (A), the disc transport path 48A of the disc reproducing unit 32A and the second disc accommodating portion 41A
-2 are aligned.

When the computer instructs to play another disk, the operation shown in FIG. 5 is performed. As shown in FIG. 5B, the disk transport mechanism 34A
Operates to hold the disk 11, then the turntable 37A moves down, the clamper 38A moves up, and the clamp of the disk 11 is released.

Subsequently, as shown in FIG. 5C, the disk transport mechanism 34A transports the disk 11 in the Y1 direction and stores it in the second disk storage section 41A-2. Finally, as shown in FIG.
1a hits the periphery of the disk 11 and holds the disk 11.

The disc reproducing apparatus 30A normally repeats the above operation. The disc playback device 30A performs the following operation in addition to the above operation, according to an operation of the operator. (3) Operation for reproducing a disk inserted from outside the disk reproducing device 30A (FIG. 6): When the operator instructs to reproduce the disk to be inserted, the operation shown in FIG. 6 is performed.

The both-side rotating mechanism 35A operates to rotate both the disk reproducing unit 32A and the disk accommodating unit 33A, and as shown in FIGS. 16A and 16A, the disk reproducing unit 32A The disk transport path 48A and the empty disk storage part, for example, the second disk storage part 41A-2 are aligned. Next, the flap 112 in FIG. 14 is rotated to open the disc insertion opening 71A.

Next, the operator inserts the disk 11 from the disk insertion slot 71A. When the disk 11 is inserted from the disk insertion slot 71, as shown in FIG.
Is transported in the Y1 direction to a position on the disk reproducing unit 32A.

Subsequently, as shown in FIG. 6C, the turntable 37A and the clamper 38A operate to clamp the disk 11 on the turntable 37A. Further, the flap 112 is returned to the original state, and the disc insertion slot 71A is closed. Finally, as shown in FIG. 6D, the rollers 61A and 60A are retracted and separated from the disk 11. Thereafter, the disc 11 is reproduced.

(4) Operation of ejecting the disc being reproduced by the disc reproducing unit 32A to the outside of the disc reproducing apparatus 30A (FIG. 7): The operator ejects the currently reproduced disc shown in FIG. 7A. , The operations shown in FIGS. 7B to 7D are performed.

As shown in FIG. 7B, the disk transport mechanism 34 A operates to hold the disk 11. Next, as shown in FIG. 7 (C), the clamp of the disk 11 is released, and the motor (not shown) is started to rotate the flap 112 in FIG. 14 to open the disk insertion port 71A. It is.

Subsequently, as shown in FIG. 7 (D), the disk transport mechanism 34A transports the disk 11 in the Y2 direction, and a part of the disk 11 projects to the outside of the disk reproducing device 30A. Thereafter, the operator operates the disk 11
And pull it out of the disc player 30A.

When the disk 11 is pulled out, the flap 112 is returned to the original state, and the disk insertion slot 71A is closed. Here, the flap 112 cannot be closed unless the operator pulls out the disk 11. That is, when a command to close the flap 112 is issued,
The disc insertion detection switch 160 (see FIG. 28), which will be described later, is turned on for a predetermined time, and the disc insertion detection switch 1 is turned on.
If 60 is off (the disk 11 is not pulled out), the instruction to close the flap 112 is not executed. Therefore, the inconvenience that the flap 112 hits the disk 11 does not occur.

(5) Operation for accommodating a disk outside the disk reproducing device 30 in the disk accommodating unit 33 (FIG. 8): an operator instructs an accommodating operation, and an accommodating section for accommodating the disk, for example, Disk storage part 41 of 3
When A-3 is designated, the operation shown in FIG. 8 is performed.

The both-side rotating mechanism 35A operates, and both the disk reproducing unit 32A and the disk accommodating unit 33A are rotated, and as shown in FIGS. 16B and 8A, the disk reproducing unit 32A The disc transport path 48A and the third disc accommodating portion 41A-3 are aligned. Next, the flap 112 in FIG. 14 is rotated to open the disc insertion opening 71A.

Next, the operator inserts the disk 11 from the disk insertion slot 71A. When the disk 11 is inserted from the disk insertion slot 71A, the disk transport mechanism 34A holds the inserted disk 11 as shown in FIG. 8B. Subsequently, as shown in FIG. 8C, the disk 11 held by the disk transport mechanism 34A is transported in the Y1 direction. The disk transport mechanism 34A transports the disk 11 through the disk transport path 48A of the disk playback unit 32A in the direction of the third disk storage section 41A-3 of the disk storage unit 33A. Also, flap 11
2 is returned to the original state, and the disc insertion slot 71A is closed.

Finally, as shown in FIG. 8D, the pressing finger 131a pushes the peripheral edge of the disk 11 to house the disk 11 in the third disk housing 41A-3 and hold the disk 11. . At this time, the disk transport mechanism 34A and the disk 11 are separated.

(6) Operation of ejecting the disk in the disk accommodating unit 33 out of the disk reproducing device 30 (FIG. 9): When the operator instructs the ejecting operation and designates the fourth disk accommodating portion 41A-4. The operation shown in FIG. 23 is performed.

The both-side rotating mechanism 35A operates, and both the disk reproducing unit 32A and the disk housing unit 33A are rotated, and as shown in FIGS. 16C and 9A, the disk reproducing unit 32A The disc transport path 48A and the fourth disc accommodating portion 41A-4 are aligned.

Subsequently, as shown in FIG. 9B, the holding of the disk 11 by the pressing finger 131a is released, and the pushing finger 131c moves the disk 11 from the fourth disk housing portion 41A-4 in the Y2 direction. Extrude a little. The disk transport mechanism 34A holds the extruded disk 11.

The disk transport mechanism 34 A is shown in FIG.
As shown in (C), the disk 11 is transported in the Y2 direction, and a part of the disk 11 is set to protrude out of the disk reproducing device 30A. Thereafter, the operator operates the disk 11
And pull it out of the disc player 30A.

As can be seen from the above description, the disc reproducing apparatus 30A has the following features. (1) The height dimension is H10, and it can be made thin. For the following reasons.

As shown in FIG. 2, the disc reproducing unit 32A and the disc accommodating unit 33A are in a facing relationship, and both can rotate and tilt. For this reason, the angle α at which the disk reproducing unit 32A must rotate is smaller than the angle at which the disk reproducing unit must rotate when the disk housing unit is fixed. Therefore, the space 81A required for the rotation of the disk reproducing unit 32A is small. The angle α is about 6 degrees.

The angle β at which the disk storage unit 33A must rotate is smaller than the angle at which the disk playback unit is fixed and only the disk storage unit must rotate. Therefore, the space 82A required for the rotation of the disk housing unit 33A is small. The angle β is about 6 degrees.

The space 81A required for the disk playback unit 32A to rotate and the space 82A required for the disk storage unit 33A to rotate are:
Most of them overlap in the Z direction. (2) The distance g1 between adjacent disks 11 housed in the disk housing portions 41A-1 to 41A-6 of the disk housing unit 33A does not become narrow.

Disk storage units 41A-1 to 41A-6
Are arranged in parallel with each other. (3) It is possible to shorten the time required from completion of a command to completion of an operation corresponding to the command.

Since both the disk reproducing unit 32A and the disk accommodating unit 33A rotate, the disk transport path 48A of the disk reproducing unit 32A and a predetermined disk accommodating portion of the disk accommodating unit 33A are aligned in a straight line. This is because it is possible to shorten the time required for this.

Next, the configuration of each unit of the disk reproducing device 30A will be described. [Configuration and Operation of Disk Transport Mechanism 34A] (FIG. 14,

1c and one pin 191d on the opposite side. The clamper 38A has an annular groove 38Ac having a central hole 1.
91a and supported by the clamper holder 191. The width w1 of the annular groove 38Ac in the Z direction and the thickness t1 of the clamper holder 191 have a relationship of w1 <t1. The clamper 38A has a play with respect to the clamper holder 191 in a dimension (t1-w1) in the axial direction of the clamper 38A.

The clamper holder 191 has pins 191b,
191c and 191d are connected to the opening 1 at the center of the chassis 103.
03d guide groove 103d formed at the edge of 03a,
It can move in the Z1 and Z2 directions by fitting with 103e and 103f. The clamper 38A protrudes toward the lower surface of the chassis 103 through the opening 103a.

The clamp slider 192 has a bifurcated fork 192a at one end.
a has diagonal cam grooves 192b, 192c, and 192d, and has a pin portion 192e on the other end side. The clamp slider 192 has oblique cam grooves 192b, 192c, 19
2d is provided on the chassis 103 so as to be slidable in the A3 and A4 directions with the pins 2b fitted to the pins 191b, 191c and 191d, respectively. The A3 direction is a direction between Y1 and X2, and the A4 direction is a direction between Y2 and X1. The pin portion 192e faces the mountain-shaped cam 140f of the loading arm 140.

The clamp slider 192 is urged in the A4 direction by a tension coil spring 193. The mountain-shaped cam 140f has slope portions 140f-1, 14f on both sides.
0f-2 and the top surface 140f-2. The oblique cam groove 192b has an upper portion 192b-1 and an oblique portion 192b.
-2 and a lower portion 192b-3.

The cam 140f causes the clamp slider 192 to move in three directions P10 and P1 in the directions A3 and A4.
1, P12. Thus, the clamper holder 191 is positioned at a high position (retraction support position) Hu, an intermediate position (intermediate support position) Hm, and a low position (rotatable support position) Hl (FIG. 17 (G)). .
The high position Hu is such that the clamper holder 191
This is a retreat support position that supports the clamp 8Ab and supports the clamper 38A at a retreat position H10 that is higher than the disc 11 and does not hinder the conveyance of the disc 11. The intermediate position Hm is a position where the clamper 38A is supported at a height position H11 in contact with the disk 11. The lower position Hl is
Flange part 38 of clamper 38A at height position H11
Ab is a position lower than Ab, that is, a position where the clamper holder 191 is separated from the flange portion 38Ab.

Next, the operation of the disc clamp mechanism 190 will be described. FIG. 17G shows the clamper holder 19.
1 and the movement of the turntable 37A is shown in FIG. First, the operation of clamping the disk 11 will be described.

When the disk transport mechanism 34A is in the initial state shown in FIG. 32, as shown in FIG. 39A, the clamp slider 192 is located at the position P10, and the clamper holder 191 is located at the high position Hu. , Clamper 38
A is located at the high position H10, and the turntable 37
A is located at a low position (retraction position) H20 which does not hinder the transport of the disk 11 (FIG. 17 (I)).

The loading arm 140 is rotated counterclockwise by the forward rotating motor 174, and
Is transported to the reproduction position, as shown in FIG. That is, the slope 140f-
1 presses the pin portion 192e, the clamp slider 192 slides in the A3 direction against the spring 193 to reach the position P11, the oblique portion 192b-2 guides the pin 191b, and the clamper holder 191 is positioned at the intermediate position. Hm, Clamper 3
8A reaches the height position H11.

In this state, as shown in FIG.
The turntable vertical movement mechanism 114 operates, the turntable 37A moves upward, reaches the support position H21 for supporting the disk 11, and the magnet 37Ac in the turntable 37A magnetically attracts the iron plate piece 38Ad in the clamper 38A, and 11 is clamped on the turntable 37A.

As described above, the turntable 37A is raised after the clamper 38A is positioned at the clamp position, so that the magnet 37Ac in the turntable 37A effectively uses the magnetic attraction force to attract the iron plate piece 38Ad in the clamper 38A. Can work.

Thereafter, the loading arm 140 further rotates counterclockwise, as shown in FIG. 39 (D). That is, the top surface portion 140f-2 of the cam 140f pushes the pin portion 192e, the clamp slider 192 further slides in the direction A3 to reach the position P12, the lower portion 192b-3 guides the pin 191b, and the clamper holder 191 reaches the lower position Hl, is separated from the flange 38Ab, and floats in the annular groove 38Ac.

Here, a case where the disc 11 is shifted from the reproduction position by a predetermined dimension or more will be described. When the turntable 37A moves upward, as shown in FIG. 40B, the turntable 37A pushes up the vicinity of the center hole of the disk 11 and deforms the disk 11 into an umbrella shape.

As shown in FIG. 40A, the clamper holder 191 is already located at the intermediate position Hm, and the allowance for the displacement of the clamper 38A in the Z1 direction is limited to the dimension b1. Therefore, the upward movement of the turntable 37A is
As shown in FIG. 40B, the position is restricted to a position H22 slightly lower than the original height position H21.

Therefore, as compared with the case where the turntable 37A moves upward to the original height position H21, the size of pushing up the vicinity of the center hole of the disk 11 is limited, and the disk 11
The deformation amount when deforming into an umbrella shape is limited to a small amount. Next, the operation for releasing the clamp of the disk will be described.

When the motor 174 rotates in the reverse direction and the loading arm 140 rotates clockwise, the state becomes as shown in FIG. That is, the slope 140f-
2 presses the pin portion 192e, the clamp slider 192 slides in the A3 direction to reach the position P11, and the oblique portion 192b
-2 guides the pin 191b, the clamper holder 191 moves up slightly, reaches the intermediate position Hm, and is in a state of supporting the flange portion 38Ab of the clamper 38A. Clamper 38
A stays at the height position H11.

In this state, as shown in FIG.
The peripheral edge of the disk 11 is gripped, and the turntable vertical movement mechanism 114 operates to lower the turntable 37A.
Therefore, the turntable 37A is separated from the clamper 38A, reaches the position H20, and the clamp of the disk 11 is released.

When the turntable 37A is moved downward, the magnetic attraction between the magnet 37Ac in the turntable 37A and the iron plate piece 38Ad in the clamper 38A is forcibly separated. Until the magnetic attraction is forcibly separated, the clamper 38A is about to be displaced downward with the downward movement of the turntable 37A. When the clamper 38A is displaced downward, the disk 11 whose peripheral edge is gripped is deformed into an inverted umbrella shape. However, the clamper holder 19
1 has already moved slightly upward to reach the intermediate position Hm, and has supported the flange portion 38Ab of the clamper 38A.
8A is in a state where downward displacement is restricted. Therefore, when the clamp is released, the disk 11 does not deform into an inverted umbrella shape.

Thereafter, the loading arm 140 further rotates clockwise, as shown in FIG. 41 (C).
That is, the pin portion 192e reaches the foot of the cam 140f,
Get over the top 140f-2. Therefore, the clamp slider 192 slides in the A4 direction to reach the position P10,
The upper portion 192b-1 guides the pin 191b, the clamper holder 191 reaches the high position Hu, the clamper 38A is slightly moved up to the high position H10, and floats from the unclamped disk 11. [Connecting Mechanism of Disk Reproducing Unit 32A and Disk Housing Unit 33A] (FIGS. 42 and 43) The disc reproducing apparatus 30A has a connecting mechanism 200.
The coupling mechanism 200 mechanically connects the disk reproducing unit 32A and the disk housing unit 33A when the disk transport mechanism 34A operates, and the two-side rotating mechanism 35
A does not operate even if it tries to operate, that is, the disk reproduction unit 32A and the disk accommodation unit 33A
And does not rotate.

As shown in FIG. 42, the connecting mechanism 200
Connecting recess 109b at the tip of eject lever 109
And the holding finger 131a at the tip of the stock arm 131
It is composed of That is, the coupling mechanism 200 is entirely composed of existing components, and is configured without using any special components.

When the disc transport mechanism 34A is in the initial state shown in FIG. 32, the eject lever 109 is
7A, the eject lever 109 and the stock arm 131 are not connected, and the disc reproducing unit 32A and the disc housing unit 33A are not connected and can freely rotate. That is, when the two-side rotating mechanism 35A operates, the disc reproducing unit 32
A and the disk accommodating unit 33A are in a rotating state.

The two-way rotating mechanism 35A operates, the disk reproducing unit 32A and the disk accommodating unit 33A rotate, and the disk reproducing unit 32A faces the predetermined disk accommodating portion 41A of the disk accommodating unit 33A. Thereafter, when the disk transport mechanism 34A starts operating, the eject lever 109 rotates in the M1 direction, and the distal end 109c of the eject lever 109 is
By pressing 1b, the stock arm 131 pivotally rotates in the N1 direction.

When the eject lever 109 starts to rotate in the M1 direction, as shown in FIG.
09b is the holding finger 13 at the tip of the stock arm 131.
Start fitting with 1a. The eject lever 109 and the stock arm 131 rotate to the position shown in FIG. 43 (C), the pressing finger 131a fits deeply into the connecting recess 109b, and the eject lever 109 and the stock arm 1
31 are mechanically connected.

As a result, the disk reproducing unit 32A
And the disk housing unit 33A are mechanically connected,
Disk playback unit 32A and disk storage unit 3
3A is a state in which the rotation is prohibited. Therefore, when the disk transport mechanism 34A is operating, the two-side rotating mechanism 35A is not electrically operated. However, for example, the control is disturbed due to noise or the like. Attempting to do so, the disk reproducing unit 32A and the disk housing unit 33A do not rotate. For this reason, the disc reproducing unit 32A and the disc accommodating unit 33A are reliably maintained in a predetermined positional relationship. Therefore, the disk transport by the disk transport mechanism 34A is reliably performed without any trouble.

The disk 11 transported outside the disk storage unit 33A and the disk storage unit 33
It is possible to reliably prevent an accident that the disk 11 is damaged due to collision with another disk 11 accommodated in A. Therefore, as shown in FIG. 12, under the condition that sufficient reliability is guaranteed, the disk reproduction unit 32
A and the disk housing unit 33A are arranged close to each other. Therefore, the disc reproducing device 30A has the depth dimension L
10 is as short as possible. Also, since the depth dimension L10 of the disc reproducing device 30A is short,
The transport distance of the disk 11 is shortened, and the time required for transporting the disk 11 is shortened.

Further, the connecting mechanism 200 may be configured such that the distal end side of the eject lever 109 locks a part of the partition plate 130 of the disk storage unit 33A. [Flap 112 and Flap Opening Mechanism 113] (FIG. 4)
4 to 46) As shown in FIG. 44 and FIG.
The hole 112a-1 of the arm 112a on the X2 side is inserted into the pin 40 on the side of the chassis 103 of the loading assembly 100.
A, the fork 112b of the arm 112b on the X1 side.
-1 is fitted to a pin 40Aa corresponding to the pin 40A so as to be rotatable in the B3 and B4 directions.

A slider 210 is provided on the X2 side of the chassis 103 so as to be slidable in the Y1 and Y2 directions. Hole 210a on the Y2 end side of slider 210 and flap 112

The slider 210 and the flap 112 are connected. The slider 210 is urged in a Y1 direction by a spring 211, and the flap 112 is urged in a B4 direction which is a closing direction. In this state, the flap 112 holds the front bezel 39 as shown in FIGS. 46 (A) and (B).
A opening 71A is closed.

The slider 210 has a finger 210b. The finger portion 210 b protrudes to a position on the chassis 103 where the finger portion 210 b is pressed by the pin 146. When the disc transport mechanism 34A operates to eject the disc 11 from the disc reproducing device 30A, FIG.
(B), as shown in FIG. 46 (C), at the final stage of the operation, that is, immediately before the disc 11 is ejected, Y
The pin 146 that has moved in two directions presses the finger 210b, the slider 210 moves in the Y2 direction against the spring 211, the flap 112 rotates in the B3 direction, and the opening 71A of the front bezel 39A is opened. . As soon as the opening 71A of the front bezel 39A is opened, the disk 11
Project from the opening 71A.

Here, the state in which the flap 112 closes the opening 71A of the front bezel 39A will be described. The flap 112 is attached to the chassis 103 of the loading assembly 100, is urged by a spring 211 in a direction B4, which is a direction in which the flap 112 is closed via the slider 210, and has a support projecting behind the opening 71A of the front bezel 39A. It hits the sponge 213 on the base 39Ab.

For this reason, as shown in FIGS. 46 (A) and (B), when the disc rotating unit 32A swings around the pins 40A and 40Aa, the slider 210 moves as shown in FIGS. Is slightly slid, so that the flap 112 is attached to the sponge 2 on the pedestal portion 39Ab.
Keep hitting 13. That is, the disc reproducing unit 32
The swing of A is absorbed by the slight sliding of the slider 210, the flap 112 continues to abut on the receiving part 212b, and the opening 71A of the front bezel 39A keeps being closed by the flap 112. In this way, even if the disk reproducing unit 32A swings, the flap 112
Since the relative positional relationship between the flap 112 and the front bezel 39A does not change, the size (height dimension) e of the flap 112 does not need to be particularly large, and a minimum size that is one size larger than the opening 71A is sufficient. Therefore, the disc reproducing device 30A
Can be made thin.

Further, the flap 112 keeps hitting the sponge 213 on the receiving portion 39Ab, and no gap is formed between the flap 112 and the sponge 213. Therefore, the portion of the opening 71A of the front bezel 39A of the disc reproducing device 30A has good dustproofness.

Further, the flap 112 is attached to the front bezel 3
9A, the ejected disk 11
For example, even when a finger is inserted into the center hole and pulled out, the flap 112 does not interfere
Is easy to pull out. [Configuration around Disc Insertion Portion Member 111] (FIGS. 47 to 49) As shown in FIGS. 47, 48A and 48B, X1, X2 of the back side of the disc insertion portion member 111 which is a resin molded product.

It is. The attachment member 221 has the arm portion 221b hooked on the hook portion 111c and the finger portions 221d, 221.
e is inserted and attached to the holes 111d and 111e.

The arms 221b and 221c extend laterally past the protrusion 111b and press the disk supporting member 220. The disk supporting member 220 is firmly attached to the same degree as the adhesive. Here, when the disk 11 is inserted, the disk supporting member 220
As shown in (A), the wings 220b and 220c are warped so as to be elastically turned up. Warped wings 220b, 220c
Supports the disk 11 with the elastic restoring force of the warped wings 220b and 220c themselves. When the disk 11 is ejected, as shown in FIG. 49 (B), the wings 220b and 220c warp and support the disk 11 in the same manner as when inserting the disk. As described above, the disc supporting member 220 is a consumable that is rubbed and gradually worn by the disc 11 each time the disc 11 is inserted or ejected, and a certain period of time has elapsed since the use of the disc reproducing apparatus 30A was started. After that it should be replaced with a new one. The mounting member 221 is easily removed by removing the finger portions 221d and 221e from the holes 111d and 111e. By removing the mounting member 221, the disk support member 220 is removed and replaced with a new one. Therefore, the disk insertion member 111
There is no need to replace the parts, and the maintainability is good.

The back surface 11 of the disk support member 220
1f is a tapered surface that faces in the Y1 direction as approaching the insertion opening 111a, and the wings 220b and 220c also have a mountain shape that is convex in the Y1 direction toward the slit 220a, and is angled in the Y1 direction with respect to the vertical surface. θ1 is inclined.

For this reason, when the disk 11 is inserted, as shown in FIG.
The angle at which c warps remains at θ2. This angle θ2 is smaller by θ1 than the warp angle when the wings 220b and 220c are vertical surfaces, and the warped wings 220b and 220c
c, the elastic restoring force is small, and the warped wings 220b, 220
The resistance force (load of the insertion of the disk 11) exerted on the disk 11 into which the c is inserted is small, and therefore, the insertion of the disk 11 is performed with a lighter force and a better feel as compared with the related art.

The center of the wings 220b and 220c where the wings 220b and 220c are warped is a position that is pressed by the arms 221b and 221c, and is a position that is vertically separated from the position of the edge of the insertion port 111a. In the configuration where the wings are bonded,
The position of the warped center is the position of the edge of the insertion port 111a. Therefore, even by this, the angle at which the wing portions 220b and 220c warp is small.

When the disc 11 is ejected and when the ejected disc 11 is pulled out, FIG.
As shown in (B), the angle at which the wings 220b and 220c warp is θ4. This angle θ4 is determined by the wings 220b, 2
The angle at which the warped wings 220b, 220c are elastically restoring force is large, and the force supporting the disk 11 from which the warped wings 220b, 220c are pulled out is larger than the warped angle when 20c is a vertical plane by θ1. Increases. Therefore,
When the disk 11 is pulled out, even if the fingertip comes off the disk 11, the disk 11 is warped to the wing 2
The disk 11 continues to be firmly supported by the disks 20b and 220c, so that the disk 11 does not come off and fall off, which is safe.

The disk supporting member 220 is not limited to felt, but may be rubber or sponge. Also,
The disk support member 220 can be applied to support a card-shaped recording medium.

[Operation when the disc 11 is inserted from the outside, the operator forcibly pulls out the disc 11 immediately after the disc transport mechanism 34A starts operation] (FIGS. 50 to 52) When the disk 11 is stored in the disk storage unit 33A as shown in FIG.
As shown in (B), when approximately three quarters of the disk 11 is inserted into the disk reproducing device 30A, the disk insertion detection switch 160 operates to be turned on.
Detector 106 inserted into substantially the entire disc 11 in disc reproducing apparatus 30A operates to be turned ON. afterwards,
The disc insertion detection switch 160 is turned off.

When the disk insertion detection switch 160 is operated and turned on, but before the detector 106 is turned on, or when the detector 106 is turned on, for example, There may be a case where the user notices an error and forcibly pulls out the disc whose transport has started. Even if this operation is performed, no inconvenience occurs in the operation of the disk reproducing device 30A.

The means is a disk insertion detection switch 1
After the state in which 60 is to be turned off has passed, that is,
At a point shortly after the disk transport mechanism 34A starts operating, the state of the disk insertion detection switch 160 and the state of the detector 1
In the state of 06, if the disk insertion detection switch 160 is OFF and the detector 106 is ON, it is determined that the disk is normal and the disk transport is continued, otherwise, it is determined that the disk is abnormal and an error occurs. Then, the disc transport mechanism 34A is returned to the initial ejection state, that is, the state of receiving the insertion of the disc.

FIG. 52 shows a control circuit 2 shown in FIGS. 1 and 50.
3 is a flowchart of a microcomputer constituting 30. If it is determined that the disc insertion detector 106 is ON (ST2), the loading motor 174 is rotated in reverse (ST4). If it is determined that the slit 140g-3 has been detected (ST5), the disc insertion detection switch 16
It is determined whether or not 0 is OFF (ST7). If the determination result is YES, the disc insertion detector 106
It is determined whether it is F (ST10). The judgment result is YE
In the case of S, it is determined whether or not the slit 140g-7 has been detected (ST12). If the result of the determination is YES, the motor 174 is stopped (ST13).

If the decision result in the step ST7 is NO,
Alternatively, if the determination result in step ST10 is NO,
An error is issued (ST14). Steps ST1,
By ST3, ST9, and ST11, the light emitting diode of the detector 106 is turned on only when it is necessary to perform detection. In steps ST6 and ST8, the light emitting diode of the disk insertion detection switch 160 is also turned on only when it is necessary to perform the detection. In FIG. 52, reference numeral 231 indicates a time during which the light emitting diode of the disk insertion detection switch 160 is on, and reference numeral 232 indicates a time during which the light emitting diode of the detector 106 is on. The light emitting diode of the disc insertion detection switch 160 and the light emitting diode of the detector 106 are not always lit, but are lit only when it is necessary to perform detection. Therefore, the power consumption of the light emitting diode can be reduced.

The slit 140g-3 is detected just before the flap 112 is closed, and if the loading is performed normally, the entire disc is loaded into the apparatus. Therefore, if the disc is loaded normally at this time, the disc is not pulled out after that, so that the disc can be reliably prevented from being pulled out.

Further, since the judgment is made before closing the flap, it is possible to prevent the disc being pulled out from colliding with the closing flap 112 and being damaged. Also, to judge before clamping (slit 140g-5),
It is possible to prevent the turntable from hitting the disk being pulled out and destroying the data on the disk.

Note that the present invention is not limited to a CD-ROM,
It can be applied to other discs such as CD, MD, and DVD.

As described above, according to the first aspect of the present invention, the flap is rotatably supported by the recording medium reproducing unit, is positioned behind the front bezel, and The front bezel is urged in a direction to close the opening by a spring, and the front bezel has a receiving base at a position along the opening on the back side of the front bezel, and the flap contacts the receiving base by the spring force of the spring. Because of the configuration in which the flaps are in contact with each other, even when the recording medium reproducing unit rotates, the flaps continue to abut on the pedestal portion, and the relative positional relationship between the flaps and the front bezel remains unchanged. Therefore, the height dimension of the flap can be made smaller than the configuration in which the flap rotates together with the rotation of the recording medium reproducing unit, and the flap can be made the minimum size. Thus, the height of the recording medium reproducing apparatus can be reduced.
