SUMMARY OF THE INVENTION An object of the present invention is to provide a reproducing / recording apparatus for a disc-shaped record carrier which can individually insert and eject a disc-shaped record carrier such as a CD, and can store a large number of small-sized record carriers.

[0007]

According to the present invention, a disk-shaped record carrier having a center hole for rotational driving can be inserted and ejected individually from an opening of a housing, and a plurality of sheets can be stored inside the housing. A reproducing / recording apparatus for a disk-shaped record carrier, wherein a plurality of record carriers can be held parallel to each other and centered on the same straight line, and a space on one surface side of the held record carrier is enlarged. Storage means that can be divided into a plurality of storage means, input means for inputting designation of an operation for the record carrier, and designation of a holding position of the storage means to be operated, and an entire storage means, or a designated holding position. An exchange means capable of reciprocating the divided storage means present on the one side in the linear direction, a transport means for transporting the record carrier between the opening of the housing and the storage means, Magnified by splitting Reproducing / recording means for reproducing and / or recording recorded information, having a central axis which can advance and retreat with respect to the space and which has a central hole of a record carrier inserted therein; A moving means mounted with a reproducing / recording means, disposed between the opening of the housing and the storing means and capable of reciprocating in a direction parallel to the straight line passing through the center of the record carrier held by the storing means; When the operation of inserting or ejecting the record carrier is designated in response to the designation to the means, the position of the transport means by the moving means and the holding position designated by the entire movement of the storage means by the exchange means are set in the housing. When the operation of reproducing and / or recording the record carrier is specified according to the position of the opening of
The position of the reproducing / recording means is adjusted to the holding position specified by the storing means by the moving means, and the one storing means including the specified holding position is divided by the exchange means, and the space enters the space enlarged by the division. And a control means for controlling the reproduction / recording means to reproduce and / or record data on / from the record carrier. According to the present invention, a plurality of disk-shaped record carriers can be held in the storage means in a state where the disc-shaped record carriers are held so that the centers pass through the same straight line. Moving means is interposed between the storage means and the opening of the housing. The transport means is provided with a transport means for transporting the record carrier, and a reproducing / recording means for reproducing and / or recording on the record carrier. The moving means is movable in a linear direction passing through the center of the record carrier held by the storage means. The control means for moving the storage means as a whole in its linear direction or dividing the storage means from the designated holding position of the record carrier to expand the space in which the reproducing / recording means can advance, comprises the input means for inserting and discharging the record carrier. When the operation is instructed, the transfer means is adjusted to the position of the opening of the housing by the moving means, and the holding position of the storage means is adjusted to the opening of the housing by the exchange means. Discharge can be performed individually. When the input means is instructed to perform the operation of reproducing and / or recording the record carrier, the control means controls the moving means and the exchanging means to change the position of the reproducing / recording means to the designated record carrier in the storage means. Since the position is adjusted to the holding position, the amount of movement of the storage means by the exchange means can be reduced as compared with a case where the reproduction / recording means is fixed and only the position of the storage means is changed to select a record carrier. Thus, a storage unit having a relatively large thickness is provided in a housing having a limited height, and a large number of record carriers can be stored.

In the present invention, the storage means can hold an outer peripheral portion in a state where a predetermined area of the record carrier is inserted, and can reproduce and / or reproduce data from the record carrier by the reproducing / recording means. Alternatively, the recording operation is performed in a state where the record carrier is pulled out from the storage means to the opening side and the holding of the record carrier to the outer peripheral portion is released. According to the present invention, the holding means may be provided with a mechanism for holding the outer circumference of the state in which a predetermined range of the record carrier is inserted, for holding the inserted record carrier. And the required thickness can be reduced. Also,
If the record carrier is pulled out of the storage means until the holding of the outer peripheral portion by the storage means is released, reproduction and / or recording can be performed, so that the distance between the storage means and the opening can be reduced.

In the present invention, the operation of reproducing and / or recording on the record carrier by the reproducing / recording means is performed in a state where at least a part of the record carrier stays in the storage means. According to the present invention, the operation of reproducing and / or recording on the record carrier by the reproducing / recording means is performed in a state where at least a part of the record carrier stays in the storing means, so that the reproducing / recording means is separated from the storing means. The device can be made smaller by reducing the distance of advance and retreat between the means and the necessary distance between the opening of the housing and the storage means.

In the present invention, the center axis of the reproducing / recording means is inserted from the inside of the center hole into the center hole of the record carrier by inserting the center axis from the one surface side of the record carrier. A resilient holding means capable of holding and rotating the carrier is provided. According to the present invention, a resilient holding means is provided on the center axis of the reproducing / recording means, and the record carrier is rotationally driven only by inserting the center axis into the center hole of the record carrier from one surface side of the record carrier. Therefore, the recording medium can be attached to and detached from the center axis only from one surface side of the recording medium, and the configuration of the exchange means can be simplified.

In the present invention, the control means causes the reproducing / recording means to advance into the space formed in the storage means divided by the exchange means when performing the operation of reproducing and / or recording the record carrier. By returning the divided portion of the storage means by the exchange means to the remaining part side, the center axis is inserted into the center hole of the record carrier at the designated holding position, and the reproducing / recording means is retracted to store the record carrier. , The record carrier is mounted on the central axis, and at the end of the reproducing and / or recording operation, the reproducing / recording means is inserted into the holding position of the storage means, and the exchange means divides the storage means. Thus, the control is performed such that the record carrier is removed from the central axis. According to the present invention, the moving of the held record carrier to the center axis of the reproducing / recording means is achieved by combining the advance / retreat operation of the reproducing / recording means and the movement of the separated storage means by the exchange means. The movement of the record carrier from the center axis to the record carrier holding position of the storage means can be switched, so that the mechanism for changing the state of the record carrier can be simplified.

Further, in the present invention, when returning the divided portion of the storage means to the remaining portion side, the control means releases the press after pressing the record carrier toward the reproducing / recording means side. It is characterized by controlling. According to the invention, when the record carrier is moved from the holding position of the storage means to the center axis of the reproduction / recording means, the recording medium is once pressed by the exchange means toward the reproduction / recording means side and then released. As a result, the exchange means moves so that the record carrier can be reliably pulled out of the storage means.

Further, in the present invention, the record carrier is handled in a substantially horizontal posture, the moving direction of the moving means and the moving direction of the replacing means are respectively substantially vertical directions, the direction in which the conveying means conveys the record carrier, and The direction in which the reproducing / recording means advances and retreats into the space is substantially horizontal. According to the present invention, since the record carrier is handled in a substantially horizontal posture, when the outer peripheral portion is held in the storage means, it can be easily held, for example, in a state where the outer peripheral portion is placed.

In the present invention, an opening of the housing is provided with an opening / closing means which opens only in a state where a record carrier can be inserted or ejected. According to the invention, the opening / closing means is provided at the opening of the housing,
Since the opening is made only in a state where the record carrier can be inserted or ejected, it is possible to prevent the record carrier from being inserted in a state where the insertion is not possible, to prevent damage to the internal mechanism and the record carrier, and to avoid malfunction.

The present invention also provides a supporting means for commonly supporting the moving means and the exchanging means, a floating means for maintaining the supporting means in a resiliently floating state in a housing, and a recording medium provided on the input means. When an insertion or ejection operation is designated, a lock means for eliminating a floating state by the floating means and fixing the support means to the housing is provided. According to the present invention, the moving means and the exchanging means are commonly supported by the supporting means, and are resiliently kept in a floating state in the housing. A recording operation can be performed. When the record carrier is inserted and ejected, the support is fixed to the casing, so that the opening of the casing does not shift from the holding position of the transporting means or the storing means, and the record carrier can be reliably inserted and ejected. .

Further, in the present invention, the reproducing / recording means has an optical pickup and optically reproduces information recorded on a record carrier. According to the present invention, since the information recorded on the record carrier is reproduced optically in a state that is hardly affected by external vibration,
It is possible to reliably reproduce information while avoiding a situation where the position of information to be reproduced is shifted due to vibration.

In the present invention, the reproducing / recording means has a reproducing / recording head which can be displaced in a direction perpendicular to a direction in which the recording / reproducing device moves in and out of the space. According to the present invention, the reproducing / recording head can be displaced in the advancing and retreating direction of the reproducing / recording means and displaced in the track direction of the record carrier. And the required distance between the storage means and the housing opening can be reduced.

As described above, according to the present invention, both the storage means and the reproduction / recording means which can be separated from the middle can be moved in the linear direction passing through the center of the record carrier stored in the storage means. In addition, it is possible to reduce the necessary moving distance of the storage means as a whole, increase the height of the storage means that can be installed within the same height of the housing, and increase the number of recordable storage media. The record carrier can be individually inserted and ejected by matching the holding position of the record carrier designated by the storage means and the transport means to the position of the opening of the housing. Since the transporting means and the reproducing / recording means can be moved simultaneously by the moving means, the transporting means does not hinder the movement of the reproducing / recording means, and the moving of the reproducing / recording means by the moving means and the storing means by the exchange means. The movement as a whole and the divided movement can be performed smoothly.

Further, according to the present invention, if the record carrier is pulled out of a state where only a predetermined range of the portion is inserted into the storage means, the holding state can be released and recording and / or reproduction can be performed. The distance required for the means to advance and retreat is reduced, and the distance from the opening on the front surface side of the housing to the storage means is reduced, so that the size of the housing can be reduced.

Further, according to the present invention, the operation of reproducing and / or recording the record carrier by the reproducing / recording means can be performed in a state where at least a part of the record carrier remains in the storage means. The space required between the opening and the storage means can be reduced, and the size of the housing can be reduced.

Further, according to the present invention, the resilient holding means is provided on the center axis of the reproducing / recording means, and the record carrier is inserted only by inserting the center axis from one surface side of the record carrier into the center hole of the record carrier. Since the holding means can be rotated and driven, the storage means can be divided by the exchange means so that only one surface of the held record carrier is expanded, and the mechanism is simplified, which is necessary for the division. The height of the space can be reduced.

Further, according to the present invention, the movement of the divided storage means by the exchange means and the advance and retreat operations of the reproduction / recording means are combined to record the recording medium from the storage means to the central axis of the reproduction / recording means. And the movement of the record carrier from the central axis to the storage means can be easily performed.

Further, according to the present invention, the recording carrier held in the storage means divided by the exchange means is mounted on the center axis of the reproducing / recording means so that the pressure is released once and then released. The center hole of the record carrier can be reliably mounted on the center axis of the reproducing / recording means.

According to the present invention, a plurality of record carriers can be accommodated in a substantially horizontal state in the accommodating means. Can be maintained.

Further, according to the present invention, since the opening / closing means for inserting the record carrier only from the opening of the housing in a state where the record carrier can be inserted and ejected is provided, the internal mechanism or the internal mechanism may be erroneously operated. Damage to the record carrier can be reliably prevented.

Further, according to the present invention, the moving means and the exchange means are resiliently held in a floating state with respect to the housing by the floating means. And / or recording can be performed. When the record carrier is inserted and ejected, the floating state by the floating means is released, so that the record carrier can be reliably inserted and ejected.

Further, according to the present invention, since information is reproduced optically from the record carrier by the optical pickup, the influence of external vibration can be reduced by the floating means, and the information can be reproduced reliably.

Further, according to the present invention, since the head for reproduction / recording is performed while being displaced perpendicularly to the forward and backward directions of the reproducing / recording means, the width of the forward / backward direction of the reproducing / recording means is reduced. However, the necessary distance between the opening of the housing and the storage means can be reduced, and the overall size can be reduced.
