Can be individually inserted or discharged into the housing 2 and reproduced by the PU unit 5. The PU unit 5 is mounted on a gantry 6 and is capable of vertical displacement and horizontal displacement in the CD4 insertion direction or in the opposite direction. Since the CD reproducing device 1 is mounted on a vehicle, vibrations and impacts are easily transmitted from outside while the vehicle is running. Therefore, during reproduction, the influence of external vibration or impact can be reduced by using the floating mechanism 7.

[0005] The stocker 3 is moved up and down
It can be divided up and down at any storage position. The PU unit 5 advances into the space formed by the division,
The CD 4 is received from the stocker 3 for reproduction, and the CD 4 whose reproduction has been completed is returned to the stocker 3. The operation of each part is controlled by the control circuit 9.

[0006] The stocker 3 and the gantry 6 are supported by a chassis 10. The chassis 10 is supported by the floating mechanism 7 so as to be floating with respect to the housing 2. When the CD 4 is inserted or ejected, the floating state by the floating mechanism 7 is released by fixing the lock claws 11. On the front side of the gantry 6,
A shutter 12 is provided, which can open and close an opening 13 for inserting and ejecting a CD 4 provided in the housing 2. When one CD 4 is inserted, it is closed so that a new CD 4 is not inserted. The CD 4 inserted from the opening 13 is sent into the stocker 3 by the transport roller 14. The transport roller is attached to the gantry 6 and is positioned at a height inside the opening 13 when the CD 4 is inserted or ejected.

Next, the CD 2 stored in the stocker 3
It is assumed that the third CD 4 from the bottom is selected and played. As shown in FIG. 53 (c), the stocker 3 is divided by the elevating / dividing mechanism 8. As shown in FIG. 53D, the height of the PU unit 5 is adjusted to the division position,
When the PU unit 5 enters the formed space, the transport roller 14 separates from the opening 13 and does not transport the CD4. For this reason, the horizontal movement of the PU unit 5 and the driving of the transport roller 14 are performed by the same motor. In FIG. 53D, the CD 4 is mounted by lowering the upper side of the divided stocker 3 on the turntable of the PU unit 5 that has entered the space.
In FIG. 53 (e), the upper side of the stocker 3 is raised, and the turntable of the PU unit 5 on which the CD 4 is mounted is moved to perform reproduction.

[0009]

In a reproducing apparatus in which only one recording medium can be inserted, it is necessary to convey the recording medium while detecting the position of the inserted recording medium with high accuracy. Alternatively, when a recording medium is placed on a tray or the like, it is necessary to perform high-precision positioning and maintain positioning accuracy such that the recording medium can be automatically attached to a reproducing mechanism after being drawn into the apparatus. If a plurality of recording media are collectively carried into the apparatus by a magazine method, the positioning accuracy can be maintained in a state where the recording media are stored in the magazine. However, the recording medium cannot be inserted and ejected one by one.
It is necessary to take out the entire magazine from the inside of the apparatus and perform a complicated operation such as replacing the recording medium.

[0010] Even in the CD reproducing apparatus 1 according to the prior application as shown in Figs. 52 and 53, it is necessary to precisely position the CD4 using an optical sensor in order to automatically perform the entire operation. is there. However, the operation of transporting the CD 4 within the limited housing 2, particularly the operation of transporting the CD 4 to the narrow storage position of the stocker 3 by the transport roller 14, becomes difficult to adjust if the configuration of the transport roller 14 is simplified. . The CD 4 to be inserted is stored and positioned in the stocker 3, and serves as a reference position for insertion and discharge with the transport roller 14 and delivery for reproduction with the PU unit 5. For this reason, actually, a lever for securely pushing the CD 4 into the stocker 3 or a stocker 3
A lever or the like for pushing the CD 4 stored therein to the position of the transport roller 14 is also required, and the mechanism is complicated.

An object of the present invention is to simplify a mechanism required for handling a recording medium individually inserted into the apparatus inside the apparatus, to reduce a space required inside the apparatus, and to downsize the whole apparatus. It is an object of the present invention to provide a reproducing apparatus for a recording medium that can perform the recording.

In this embodiment, the insertion / ejection roller 35 is driven by the elevating motor 52. The insertion / ejection roller 35 is lowered only when the CD 24 is inserted or ejected, and rises in other states. Therefore, in order to simplify the mechanism, the insertion / ejection roller 35 is always provided with the elevation motor 52. From the drive. When the vertical movement of the stocker 23 is required, the clutch mechanism is operated to connect the driving force to the vertical slide plate 54 so as to be transmitted. The clutch mechanism according to the present embodiment shuts off the driving force from the elevation motor 52 to a state where it is not transmitted to the elevation slide plate 54 when the division slide plate 56 is at the most retracted position. When the dividing slide plate 56 moves away from the rearmost position, the clutch mechanism 58 disconnects so that the driving force from the motor 52 is not transmitted to the elevating slide plate 54.

FIG. 13 shows a configuration of a slide unit 60 formed on the slide base 30 for moving the PU unit 25. FIG. 14 shows the slide unit 60.
A state in which the slide plate 61 is moved rearward with respect to the slide base 30 is shown in a plan view. FIG.
FIG. The slide unit 60 generally has a slide plate 61 and a turning plate 62. The slide plate 61 is movable in the front-rear direction with respect to the slide base 30. The revolving plate 62 can be revolved around a revolving shaft 63 provided on the base end side such that the PU unit 25 on the distal end side draws an arc with respect to the slide plate 61. The slide plate 61 is formed with an arc-shaped guide groove 64 for guiding when the turning plate 62 turns. An L-shaped guide groove 65 is formed in the slide base 30 and has a vertical groove 66 and a horizontal groove 67. The turning shaft 63 is provided with a protrusion 68 that engages with the L-shaped guide groove 65 of the slide base 30, while the protrusion 68 is engaged with the lateral groove 67 of the L-shaped guide groove 65, Is engaged with the arc-shaped guide groove 64 of the slide plate 61, and the turning plate 62
Is performed. When the projection 68 of the swinging plate 62 engages with the vertical groove 66 of the L-shaped guide groove 65, the revolving plate 62 cannot perform further pivoting displacement, and the vertical groove 66 and the projection 68 Can be moved only in the front-rear direction in the state in which is engaged.

The movement of the PU unit 25 on the revolving plate 62 is performed by the feed motor 70 rotating the feed screw shaft 71. The PU origin switch 72 detects that the PU unit 25 is at the origin position on the turntable 38 side. In a general PU unit, when the PU unit reaches the origin position, the feed motor 70 is not further driven. In this embodiment, the PU unit 2 is located at the origin position.
The feed motor 70 is further driven without mechanically stopping the lock 5, so that the clamping state by the chucking mechanism 40 can be released. The release of the clamp state is detected by the clamp release switch 73. The turntable 38 is directly driven to rotate by a spindle motor 74.

The relative movement of the slide unit 60 with respect to the slide base 30 is driven by a slide motor 75. Slide motor 75 is slide base 3
The movement position of the slide plate 61 is detected by a slide origin switch 76, a slide completion switch 77, and an insertion / ejection standby switch 78, respectively. In the gear mechanism for transmitting the driving force from the slide motor 75 to the slide plate 61 in the slide unit 60, a slip mechanism 79 is provided to prevent transmission of excessive driving force. When the slide plate 61 moves forward, the pins 61a
Comes into contact with a predetermined insertion / ejection mechanism 34 and stops.

Incidentally, on the back side of the slide base 30,
As shown in FIG. 13, the floating shaft 60a, the lock shaft 60b, and the lock piece 60c protrude. The floating shaft 60a is used to make the slide unit 60 in a floating state. The lock shaft 60b and the lock piece 60c are used to release the floating state.

FIG. 16 shows the structure of the slip mechanism 79. In the slip mechanism 79, two gears 79b and 79c are provided on a common shaft 79a. The gear 79b connected to the slide motor 75 is fixed to the shaft 79a. Gear 79c connected to slide plate 61 side
Is not fixed with respect to the axis 79a and can rotate about the axis 79a. The gear 79c has a shaft 79a
The driving force is transmitted by the frictional force between the gear 79c and the retaining ring 79d because the retaining ring 79d is pressed by the spring 79e.

When the driving force exceeds the frictional force, the gear 79b
The driving force transmitted from the shaft 79a to the shaft 79a is not transmitted from the retaining ring 79d to the gear 79b, but runs idle. As a result, the slide plate 61 reaches the state where the slide unit 61 is most protruded from the slide base 30 and the PU unit 25 enters the stocker 23, or the state where the slide plate 61 is most pulled back from the slide base 30. When the machine is stopped due to mechanical contact, the slip mechanism 79
Becomes idle. If sufficient control is performed until the slip mechanism 79 idles, the slide motor 75 is driven and then the control to stop the slide motor 75 is performed, so that the stop position of the slide plate 61 can be determined with high accuracy. In control in which the position is detected and stopped using an optical sensor or the like, accurate positioning is difficult due to the influence of mechanical control delay or the like. In this embodiment,
High-precision positioning can be performed reliably with simple control.

The linear movement of the slide unit 60 is as follows.
The driving force from the slip mechanism 79 is transmitted to both sides of the slide base 30 by an interlocking shaft, and is performed via a gear mechanism having the same configuration. Since both sides are driven simultaneously and evenly, smooth movement becomes possible.

As the opening / closing mechanism, opening / closing pins 89 arranged in pairs on both sides prevent double insertion of the CD 24. At the time of inserting the first CD24 or ejecting the CD24, the opening / closing pin 89a operates so that the movement of the CD24 is not hindered.
The pressure contacting the CD 24 allows the CD 24 to escape from the moving range. To prevent double insertion, the opening / closing pin 89a is prevented from being displaced by the opening / closing stopper 89b, so that it does not escape even if the CD 24 comes into contact with it.
Is prevented from moving. As described above, the shutter member 88c moves the insertion / ejection roller 35 relative to the CD 24 once inserted.
This is used when performing positioning by rotating the.
