Abstract

PROBLEM TO BE SOLVED: To provide a reproducing device into which a recording medium can be safely loaded. SOLUTION: When an AC power is first supplied to a disk reproducing device, a central processing unit CPU acquires a disk storing state from a sensor input part and a switch input part (S11), and it is decided whether a disk is stored in the disk reproducing device (S12). When no disk is stored in the disk reproducing device, the CPU drives a motor in the disk ejecting direction (S13) and then stops the drive of the motor (S15) when a prescribed time passed (S14). Thus, even a slide bar having its position shift can be moved to its original position by driving the motor in the disk ejecting direction for a prescribed time.

Hereinafter, the operation of the disk reproducing apparatus 1 according to the embodiment of the present invention will be described with reference to the drawings. First, an initial ejection process for moving the position of the slide bar 57 to the initial position will be described with reference to FIG. The slide bar 57 may be shifted to a position different from the initial position due to transportation or the like when the disc reproducing device 1 is shipped. When the disc 2 is loaded with the slide bar 57 shifted, the down switch 56 is pressed before the disc 2 reaches the turntable 55. Therefore, it is necessary to move the position of the slide bar 57 to the initial position.

FIG. 5 is a flow chart for explaining the initial ejection process. The initial ejection process shown in FIG. 5 is started when the power is first turned on by the user after the AC power is supplied to the disc reproducing apparatus 1.

First, the CPU 14 acquires the storage state of the disk from the sensor input unit 31 and the switch input unit 32 (step S11). That is, the CPU 14 acquires the storage state of the disk 2 according to the inputs from the sensors 51 to 54 and the input from the down switch 56. Then, the CPU 14 determines that the disk 2 is
(Step S1).
2).

When the CPU 14 determines that the disk 2 is stored, the initial ejection process ends. That is, if the disc 2 is stored in the disc reproducing apparatus 1, it is not necessary to move the position of the slide bar 57 to the initial position.
In order not to eject the file against the user's intention, the initial ejection process ends.

On the other hand, if it is determined that the disk 2 is not stored, the CPU 14 moves the motor 3 in the ejection direction.
5 is driven (step S13). That is, CPU
The unit 14 controls the load mute output unit 33 and the loading output unit 34, and drives the motor 35 in the ejection direction. More specifically, the CPU 14 sets the output of the load mute output unit 33 to “Hi” and sets the output of the loading output unit 34 to “Hi”,
The motor 35 is driven in the ejection direction.

The CPU 14 keeps driving the motor 35 for a predetermined time (step S14). For example, the CPU 14
Drives the motor 35 in the ejection direction for 3 seconds. As described above, by driving the motor 35 in the ejecting direction for a predetermined time, even if the position of the slide bar 57 is shifted, the slide bar 57 can be moved to the initial position.

After a predetermined time has elapsed, the CPU 14
5 is stopped (step S15). That is,
The CPU 14 sets the output of the load mute output unit 33 to “L”.
ow ”, and the driving of the motor 35 is stopped.

As described above, by the initial ejection process,
Even if the slide bar 57 has shifted, it can be returned to the initial position. Then, when the disk 2 is loaded by a loading process described later, the slide bar 57 accurately presses the down switch. As a result, since the disc 2 is not caught in the insertion slot, the disc 2 can be safely loaded.

Next, a loading process performed by the disc reproducing apparatus 1 will be described with reference to FIG. FIG. 6 is a flowchart for explaining a loading process for loading the disc 2 and chucking the turntable 55. The loading process shown in FIG. 6 starts after the above-described initial ejection process is performed.

First, the CPU 14 waits for processing until the sensor 51 is turned on (step S21). That is, the CPU 14 waits for processing via the sensor input unit 31 until the sensor 51 serving as a loading start detection sensor detects that the user has inserted the disc 2 into the insertion slot.

When determining that the sensor 51 has been turned ON, the CPU 14 sets an error timer (step S22). That is, the CPU 14 sets a predetermined time in a timer unit (not shown) for detecting an operation error of the disk loading mechanism.

The CPU 14 drives the motor 35 in the loading direction (step S23). That is, CP
U14 sets the output of the load mute output unit 33 to "Hi".
And the output of the loading output unit 34 is set to “Lo”.
By setting “w”, the motor 35 is driven in the loading direction.

In the CPU 14, the down switch 56 is turned on.
It is determined whether or not has become (step S24). That is, the CPU 14 determines via the switch input unit 32 whether or not the down switch 56 has been pressed by the sliding movement of the slide bar 57 synchronized with the driving of the motor 35.

In the CPU 14, the down switch 56 is turned on.
If not, it is determined whether or not the error timer set in step S22 has timed out (step S25).

If the CPU 14 determines that the time is not up, the process returns to step S24. on the other hand,
If it is determined that the time is up, the CPU 14 stops driving the motor 35 (step S26). That is, the CPU 14 sets the output of the load mute output unit 33 to “Low” and stops driving the motor 35.

When the driving of the motor 35 is stopped, the CPU 14 displays a predetermined error message or the like on the display section 20 and abnormally ends the loading process.

If it is determined in step S24 that the down switch 56 is ON, the CPU 14 stops driving the motor 35 (step S27). Then, when the down switch 56 is pressed by the slide bar 57, the disk lifting / lowering mechanism is operated, and the disk 2 is chucked to the turntable 55.

The CPU 14 determines whether the sensor 51 is ON (step S28). In this case, the sensor 51 is used to determine whether the loaded disc 2 is a 12 cm disc or an 8 cm disc.

When determining that the sensor 51 is ON, the CPU 14 stores information indicating that the loaded disk 2 is a 12 cm disk in the RAM 11 (step S29).

On the other hand, if it is determined that the sensor 51 is not ON, the CPU 14 determines that the loaded disc 2 is 8c.
Information indicating that the disk is an m disk is stored in the RAM 11 (step S30).

As described above, the disc 2 is accurately loaded by the loading process. This is because the slide bar 57 has been returned to the initial position in the above-described initial ejection process. Therefore, the loading process can load the disc 2 safely, in combination with the initial ejection process.

Next, the ejection process performed by the disc reproducing apparatus 1 will be described with reference to FIG. FIG. 7 is a flowchart for explaining an ejection process for ejecting the disk 2 stored in the disk reproducing device 1. The ejection process shown in FIG. 7 starts after the disc 2 is loaded by the above-described loading process.

First, the CPU 14 sets the disc ejection key 4
3 is pressed (step S3).
1). That is, the CPU 14 sets the disc ejection key 43
The process waits until a signal indicating that is pressed is input via the I / O port 16.

When the CPU 14 determines that the disc ejection key 43 has been pressed, it sets an error timer (step S32). The CPU 14 drives the motor 35 in the ejection direction (Step S33). That is, C
The PU 14 sets the output of the load mute output unit 33 to “H”.
i ”and the output of the loading output unit 34 is set to“ H ”.
By setting “i”, the motor 35 is driven in the ejection direction.

The CPU 14 controls the disc 2 to be ejected.
Is a 12 cm disc (step S34). That is, the CPU 14 determines whether or not the information stored in the RAM 11 is a 12 cm disk. When determining that the disk is a 12 cm disk, the CPU 14 determines whether or not the sensor 54 has been turned off (step S35). That is, the CPU 14
The sensor 54, which is a cm disk ejection stop position sensor,
It is determined whether the completion of ejection of the disk 2 has been detected.

When determining that the sensor 54 is not OFF, the CPU 14 determines whether or not the time of the error timer set in step S32 has expired (step S36). When determining that the time is not up, the CPU 14 returns the process to the above-described step S35.

If it is determined in step S34 that the disc is not a 12 cm disc, the sensors 52 and 53 are turned off.
It is determined whether or not has become (step S37). That is, the CPU 14 determines whether or not the sensors 52 and 53, which are 8 cm disc ejection stop position sensors, have detected the completion of ejection of the disc 2. The CPU 14 controls the sensor 5
If it is determined that both 2, 53 are not OFF, step S3
It is determined whether the error timer set in step 2 has timed out (step S38). The CPU 14
If it is determined that the time is not up, the above-described step S
The process returns to 37.

If the CPU 14 determines in step S36 or S38 that the time is up,
The driving of the motor 35 is stopped (step S39). That is, the CPU 14 sets the output of the load mute output unit 33 to “Low” and stops driving the motor 35.
When the driving of the motor 35 is stopped, the CPU 14 displays a predetermined error message or the like on the display unit 20 and abnormally ends the ejection processing.

In step S35 or S37, the CPU 14 determines whether the sensor 54 or the sensor 5
When it is determined that the switches 2 and 53 are OFF, the driving of the motor 35 is stopped (step S40). In this way, the disc 2 is properly ejected by the ejecting process. As described above, the disk reproducing apparatus according to the present invention can load a disk safely.

In the above-described embodiment, the initial ejection process is started when the user first turns on the power after the AC power is supplied to the disc reproducing apparatus 1. However, the start timing of the initial ejection process is arbitrary. . For example, the initial ejection process may be started at the time of power-on reset when AC power is supplied to the disk reproducing device 1.

In the above-described embodiment, the slot-in type disc reproducing apparatus has been described.
The present invention is not limited to such a slot-in type disk reproducing apparatus, but is also applicable to a disk reproducing apparatus that performs loading by a loading mechanism and an elevating mechanism.

In the above embodiment, the disk reproducing apparatus for reproducing a CD has been described. However, the medium to be reproduced is not limited to a CD.
(Digital video disk) and the like can be applied to a disk reproducing apparatus for reproducing. Further, a playback device that can play back a medium such as SmartMedia (trademark) or Memory Stick (trademark) may be used.

The disk reproducing apparatus of the present invention can be realized by using a normal computer system capable of reproducing a CD-ROM or the like without using a dedicated system. For example, a medium (floppy disk, CD, etc.) storing a program for executing any of the above in a computer
By installing the program from a ROM or the like, a disk reproducing apparatus that executes the above-described processing can be configured.

The medium for supplying the program to the computer may be a communication medium (medium for temporarily and fluidly storing the program, such as a communication line, a communication network, or a communication system). For example, the program may be posted on a bulletin board (BBS) of a communication network and distributed via the network. Then, by starting this program and executing it in the same manner as other application programs under the control of the OS, the above-described processing can be executed.
