Description

Description: TECHNICAL FIELD The present invention relates to a recording medium reproducing apparatus that stores a recording medium and reproduces the recording medium.

2. Description of the Related Art There is known a so-called magazine disc player which houses a plurality of (for example, 6) CD magazines in a housing called a CD magazine in a freely protruding manner, and makes this magazine detachable and selectively plays a CD.

There is already known an apparatus in which such a magazine disk player is arranged at an appropriate place in a vehicle (for example, in a trunk) and a plurality of disks are selectively played by remote control from a vehicle interior.

By the way, when a magazine is ejected for the exchange of a magazine during operation of the magazine disc player and then a new magazine is re-mounted, an operation command for restarting the player operation by a user operation is required. this is,
If the player starts playing simply by attaching the magazine again after ejecting to the magazine, for example, the user may leave the vehicle as it is, which is dangerous, and the user can play the disc even if the user is in the vehicle. This is to prevent unnecessary consumption of the battery when there is no intention.

However, the size of a magazine disk player itself has been reduced, and the number of users who install the device in a vehicle compartment, for example, near a driver's seat or a passenger seat, has been increasing. When such an installation is performed, the user can easily exchange the magazine. However, each time the magazine is exchanged, the operation of the player must be performed, which is extremely complicated.

SUMMARY OF THE INVENTION [Object of the Invention] Accordingly, an object of the present invention is to provide a recording medium reproducing apparatus that automatically starts reproduction without performing a reproduction operation when a recording medium such as a disk is replaced. .

[Constitution of the Invention] A recording medium reproducing apparatus according to the present invention comprises: a holding unit for holding a player-on mode for performing an automatic reproduction operation of a recording medium; a releasing unit for releasing the player-on mode; Detecting means for detecting that the recording medium has been inserted; reproducing means for executing reproduction of the recording medium; and discharging means for discharging the recording medium from the recording medium reproducing apparatus. When the insertion of the medium is detected, and when the player-on mode is held in the holding unit, the reproducing unit reproduces the recording medium.

[Operation of the Invention] In the recording medium reproducing apparatus according to the present invention, the player-on mode is maintained until the player-on mode is released, and when the recording medium is inserted, the reproduction of the recording medium is automatically performed without performing the reproducing operation. Start.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

In FIG. 1, an operation unit 1 includes a system controller 2, a key switch unit 3, a display unit 4, a communication circuit 5, and the like. The system controller 2 receives an operation command by a user's operation of the key switch unit 3, Information is exchanged with the player unit 6 via the connection unit 12 such as an optical fiber via the communication circuit 5. The player unit 6 includes a player controller 7, a disk drive unit 8 having an eject button 11 protruding therefrom, a communication circuit 9, and the like. The player controller 7 communicates with the operation unit 1 via the connection unit 12 via the communication circuit 9. , And controls a series of operations of the disk drive unit 8, and detects the attachment / detachment of the detachable magazine 10 by the eject button 11 and a mechanism (not shown) provided in the disk drive unit.

The display unit 4 in the operation unit 1 displays the operation state of the key switch unit, the presence or absence of the magazine 10 obtained by transmitting and receiving information, and the like.

In the above configuration, the operations of the system controller and the player controller 7 will be described with reference to the flowcharts of FIGS. 2 (a) and 3.

In FIG. 2 (a), when the power is turned on, necessary initial settings are made (step S1), and communication is performed with the player section 6 to exchange information (step S2). During this communication, the state of the player section and the like are recognized and grasped. Then key switch part 3
Is determined (step S3). If there is no key input, the process proceeds to step S2. If it is determined that there is a key input, it is determined whether the key input operation command is a player-on command (step S3). Step S4). If it is determined that the command is the player-on mode command, it is determined whether or not the magazine 10 is mounted (step S5). If the magazine is not mounted, the process proceeds to step S2. Is transmitted (step S6). Subsequently, a CD-ON process in the operation unit 1 such as turning on a CD-ON indicator (not shown) of the display unit 4 is performed (step S7),
Move to step S2. If it is determined in step S4 that the command is not a player-on command, it is determined whether or not the operation command is a player-off command (step S8). If it is determined that the command is not a player-off command, other sources (cassette tape, radio, etc.) are turned on. It is determined whether the command is a command (step S11). If it is determined that the command is not another source-on command, the process proceeds to step S2. If it is determined in step S8 that the command was a player-off command, or if step S11
If it is determined that the command is another source-on command, a player-off command is sent to the player section 6 (step
S9), the CD-off process is performed (step S10), and then the process proceeds to step S2.

As described above, once the player ON command is received by key input, the player ON mode is set, and the player ON mode is maintained unless there is a player OFF command (including other source ON commands).

The player-on mode is a mode in which a disc is played automatically when a magazine is mounted.

On the other hand, the player controller 7 of the player section 6 performs necessary initialization after turning on the power (step S36), and subsequently communicates with the operation section 1 to exchange information (step S1).
9). It is determined whether or not there is a command in the information obtained in step S19 (step S20). If it is determined that there is a command, it is determined whether or not it is a player-on command (step S21). In the case of a player-on command, it is determined whether or not the magazine 10 is mounted (step S2).
2) If it is attached, perform performance processing (step S
23), set the value of the on flag indicating the player on mode to 1
(Step S24), and then the process proceeds to step S28.
If it is determined in step S21 that the command is not a player-on command, it is determined whether or not the command is a player-off command (step S25). If it is determined that the command is a player-off command, performance stop processing is performed (step S26). The value is set to 0 (step S27), and the process proceeds to step S28. If it is determined in step S20 that there is no command, if it is determined in step S22 that the magazine 10 is not mounted, and if it is determined in step S25 that the command is not a player-off command, the process proceeds to step S28. That is, from step S19 to step S2
Steps up to 8 show the operation of the player controller 7 according to the operation command of the operation unit 1.

In step S28, it is determined whether or not the magazine 10 is mounted. If it is determined that the magazine 10 is mounted, it is determined whether or not a disc (not shown) in the magazine is being played (step S2).
9) If it is during performance, it is determined whether or not the eject button 11 has been operated (eject is on) (step S3).
2) If it is not eject-on, the process proceeds to step S19, and the player section 6 continues playing unless a player-off command is issued. Upon receiving the eject-on command, the controller 7 performs an eject process (step S33),
The process moves to step S19 to perform a communication process. Subsequently, if there is no command in step S20, if the magazine has not been remounted, it is determined in step S28 that there is no magazine, and whether or not the magazine has been reinserted is determined by a magazine insertion sensor (not shown) provided in the disk drive unit. ) (Step S34), and if not inserted, step S19
Then, if inserted, a loading process is performed (step S35). Subsequently, after step S19 and step S20, it is determined in step S28 whether or not the magazine has been completely mounted. If the magazine has been mounted, it is remounted in this case, so that it is determined in step S29 that the magazine is not being played yet. If there is no player-off command from the ejection-on to the step S30, the player is in the player-on mode, the on-flag value is determined to be 1 in the step S30, and the performance processing is performed (step S31).

When a player-off command is sent from the system controller 2 to the player unit 7, time management from eject-on to re-attachment may be performed, and a time management condition is considered with reference to FIG. 2 (b). explain. FIG. 2 (b) is obtained by adding a time management routine R1 to the operation of the system controller 2 shown in FIG. 2 (a). In the routine R1, it is determined whether or not the player is in the ON mode (step S12). If it is determined that the mode is the ON mode, it is determined whether or not the magazine 10 is mounted (step S1).
3) If it is determined that the magazine 10 is not present, that is, if the magazine has been ejected, it is determined whether or not the timer in the system controller 2 has expired (time over) (step S14). (Step S17) If there is no player-off command by key input, the process proceeds to Step S2, where Step S3 and Step S1 are performed.
2. The circulation of steps S13 and S14 is repeated, and the timer is counted. If the magazine 10 is mounted before the end of the timer (information of mounting is transferred from the player controller to the system controller by communication processing),
In step S13, it is determined that there is a magazine, the timer is reset (step S18), and the process proceeds to step 2, where no player-off command is transmitted. If magazine 10 is not installed before the timer expires, step
In S14, it is determined that the timer has ended, a player-off command is sent (step S15), and CD-off processing is performed (step S16), whereby the player-off mode is set.

Effect of the Invention As described above, in the recording medium reproducing apparatus according to the present invention, when the player is in the player-on mode when the recording medium is inserted, the reproduction is automatically started. The regeneration operation is not required every time the exchange is performed. The player-on mode can be released by a player-off command as needed. Furthermore,
If the recording medium is not inserted within a predetermined time after the recording medium is ejected, the player-on mode is canceled, so that careless automatic reproduction can be prevented.
