Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage medium reproducing apparatus particularly suitable for a portable CD player, and more particularly to a hold switch for inhibiting all switch inputs.

[0002]

2. Description of the Related Art In a portable CD player, a hold switch is provided to prevent a switch from being erroneously pressed and an operation not intended by a user from being set. . When the hold state is set by the hold switch, all switch inputs are not accepted. For this reason, if a portable CD player is provided with a hold switch, by setting the hold switch to the hold state, the device switch is erroneously set when the device is put in a bag and goes out. It can be prevented from being erroneously set by being pushed.

In a conventional portable CD player,
As this hold switch, a slide switch is employed. The slide switch, as shown in FIG.
It is composed of terminals 101A, 101B, 101C and a slider 102. When the slider 102 is on the A side, the terminals 101A and 101B are connected. When the slider 102 is on the B side, the terminals 101B and 10B are connected.
1C is connected.

[0004] Since the slide switch is switched by sliding the slider 102, the state can be maintained. Therefore, if a slide switch is used as the hold switch, there is an advantage that it can be checked at a glance whether or not the switch is in the hold state from the switch position.

[0005]

[0005] Portable CD players are often used outdoors and are required to have improved waterproofness. Therefore, a portable CD player in which switches are covered with a waterproof material such as rubber has been developed.

However, it is difficult to employ a slide switch as a hold switch in a portable CD player having a structure in which switches are covered with a waterproof material in order to enhance waterproofness. In other words, if the switches are covered with a waterproof material such as rubber, the slide operation becomes difficult with a switch that slides and holds the slider like a slide switch. Therefore, it is conceivable to use a push button switch instead of the slide switch as the hold switch.

As shown in FIG. 8, the push button switch includes a terminal 111A, a terminal 111B, and a push button 112.
When the push button 112 is pressed, the terminals 111A and 111B are connected, and the push button 11
When 2 is separated, the terminals 111A and 111B are separated. With such a push button switch, the state is restored, so that even if it is covered with a waterproof material such as rubber, the operation is not hindered.

However, the push button switch returns to the original state when the push button is released, so that the hold state / hold release state cannot be maintained from the switch state. Therefore, when a push button switch is used as the hold switch, it is conceivable to set the hold state / hold release state by a toggle operation with the switch being turned on as a trigger. That is, it is conceivable to set the hold state once the push button switch provided as the hold switch is pressed, and to set the hold release state when the push button switch is further pressed.

However, if the hold state / hold release state is set by the toggle operation as described above, it becomes difficult for the user to confirm whether or not the state is the hold state. For this reason, when switch input cannot be performed because the switch is set to the hold state, the user may erroneously determine that a failure has occurred.

When a push button switch is used as a hold switch and a hold state / hold release state is set by a toggle operation, the hold state is erroneously set when the device is put in a bag and goes out. It may be set or the hold state is released.

Further, the user sets the hold state only in a special case where the user puts the device in a bag and carries the device. Except for such a case, it is desired that the hold state is released and the switch input can be performed immediately. For example, after loading a disc, the user usually presses a playback switch or a search switch to start playing the loaded disc. As described above, when the reproduction is to be started after the disc is mounted, if the hold state is set, an operation for releasing the hold state is required.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a storage medium reproducing apparatus capable of preventing a mistaken operation in a hold state or a hold release state when a push button switch is used as a hold switch. is there.

Another object of the present invention is to provide a storage medium reproducing apparatus in which a hold switch can be easily provided with a waterproof structure.

Still another object of the present invention is to provide a storage medium reproducing apparatus capable of confirming at a glance whether or not a hold state has been established.

As described above, the CD to which the present invention is applied
The player 1 has a hold button 12 (input section 67) that prohibits all switch inputs so that the switch is not pressed by mistake when carrying the device in a bag and carrying around.
Is included). In the CD player 1 to which the present invention is applied, a push button switch is used as the hold button 12 to enhance waterproofness. A CD to which the present invention is applied so that it is possible to easily confirm whether or not a hold state is established even when a push button switch is used as the hold button 12.
In the player 1, whether or not the display 18 (display section 69) is displayed is displayed. Then, in order to prevent the hold button from being set / released by mistake by pressing the hold button, the hold state is set / released when the hold button 12 is kept pressed for a predetermined time or more. .

That is, to set the hold state, the hold button 12 is pressed. Hold button 1
When the button 2 is continuously pressed for a predetermined time or longer, a hold state is set. When the hold state is set, a key-shaped display 81 is displayed on the display 18 as shown in FIG. From this display 81, the user can see at a glance whether or not it is in the hold state.

To release the hold state, the hold button 12 is pressed again. If the hold button 12 is pressed again for a predetermined time or more, the state is set to the state of releasing the hold. When the hold is released, the key-shaped display 81 is erased from the display 8.

Further, in the CD player 1 to which the present invention is applied, when the hold button 12 is kept pressed for a predetermined time or more, the hold state is set / released by a toggle operation, and when the lid 2 is opened. Also, when the power adapter is attached to the external power jack 21 or when the power is reset, the hold state is released. Therefore, operability is improved. For example, after loading a disc, the user usually presses a play key or a search key to start playing the loaded disc. At this time, if it is set to the hold state, usually after releasing the hold state after replacing the disk,
You have to press play key or search key. However, in the CD player 1 to which the present invention is applied, when the lid 2 is opened, the hold state is released, so that the operation of releasing the hold state becomes unnecessary, and the reproduction key and the search key can be operated as it is. .

FIG. 5 is a flowchart showing the processing when the hold button 12 is operated to set / cancel the hold state.

In FIG. 5, it is determined whether or not the hold button 12 has been pressed (step S1). If it is determined in step S1 that the hold button 12 has been pressed, it is determined whether the status flag is on (step S2). Hold button 1 in step S1
If it is determined that 2 has not been pressed, the status flag is cleared (step S3), and the process goes to step S9, where a counter for measuring time is initialized.

If it is determined in step S2 that the status flag is set to ON, the process returns to step S1.

If it is determined in step S2 that the status flag is not ON, a counter for measuring time is advanced (step S4). Then, it is determined whether the counter has exceeded a predetermined value (step S5). If the counter value has not exceeded the predetermined value, the process returns to step S1.

When the value of the counter exceeds a predetermined value, a status flag is set (step S6), and the state is switched between the hold state and the hold release state (step S6).
7) The display on the display 18 is switched in response to switching between the hold state and the hold release state. Then, the counter is initialized (step S
9), and the process returns to step S1.

For example, it is assumed that the hold button 12 has been pressed while the hold state has been released.

When the hold button 12 is pressed in this state, it is determined in step S1 that the hold button 12 has been pressed, and in step S2, it is determined whether the state flag is on. Since the state flag is cleared before the hold button 12 is pressed, it is determined in step S2 that the state flag is not on. Therefore, the counter for measuring time is advanced in step S4, and it is determined in step S5 whether the counter has exceeded a predetermined value. If the predetermined time has not elapsed since the hold button 12 was pressed, it is determined in step S5 that the value of the counter has not exceeded the predetermined value, and the flow returns to step S1.

When the hold button 12 is kept depressed, the time measurement counter is advanced during this time, and the value of the time measurement counter approaches a predetermined value.

Before the predetermined time elapses, the hold button 1
2 is released, the halt switch 12 is turned on in step S1.
Is determined not to be pressed, the status flag is cleared in step S3, the counter is initialized in step S9, and the process returns to step S1. For this reason, if the hold button 12 is released before the predetermined time has elapsed, switching between the hold state and the hold release state is not performed, and
Hold release state is maintained.

Until a predetermined time has elapsed, the hold button 12
If is kept pressed, it is determined in step S5 that the value of the counter has exceeded a predetermined value. If it is determined in step S5 that the value of the counter has exceeded a predetermined value, a state flag is set in step S6, and the state is switched between the hold state and the hold release state. In this case, since the state up to that point was the hold release state, the state is switched from the hold release state to the hold state.

Then, based on the setting of the hold state in step S7, the display 81 (FIG. 4) is displayed on the display 18 in step S8. Then, in step S9, a counter for measuring time is initialized, and the process returns to step S1.

Further, if the hold button 12 is continuously pressed, it is determined in step S1 that the hold button 12 has been pressed, and it is determined in step S2 that the status flag is ON. Therefore, a loop of steps S1 and S2 is performed, and the loop is held in the hold state.

When the hold button 12 is released after a predetermined time has elapsed, it is determined in step S1 that the hold button 12 has not been pressed, the state flag is cleared in step S3, the counter is initialized in step S9, and the step It returns to S1. Therefore, the holding state is maintained.

Next, the state up to that point is the hold state,
It is assumed that the hold button 12 has been pressed.

When the hold button 12 is pressed in this state, it is determined in step S1 that the hold button 12 has been pressed, and in step S2, it is determined whether the state flag is on. Since the state flag is cleared before the hold button 12 is pressed, it is determined in step S2 that the state flag is not on. Therefore, the counter is advanced in step S4, and it is determined in step S5 whether the counter has exceeded a predetermined value. If the predetermined time has not elapsed since the hold button 12 was pressed, it is determined in step S5 that the value of the counter has not exceeded the predetermined value, and the flow returns to step S1.

When the hold button 12 is kept depressed, the counter for measuring time is advanced during this time, and the value of the counter for measuring time approaches a predetermined value.

Before the predetermined time elapses, the hold button 1
2 is released, the halt switch 12 is turned on in step S1.
Is determined not to be pressed, the hold flag is cleared in step S3, the counter is initialized in step S9, and the process returns to step S1. For this reason, if the hold button 12 is pressed before the predetermined time is measured, switching between the hold state and the hold release state is not performed, and the hold state is maintained.

Hold button 12 until a predetermined time elapses
If is kept pressed, it is determined in step S5 that the value of the counter has exceeded a predetermined value. If it is determined in step S5 that the value of the counter has exceeded a predetermined value, a state flag is set in step S6, and the state is switched between the hold state and the hold release state. In this case, since the previous state is the hold state, the state is switched from the hold state to the hold release state.

In step S7, the display 81 is erased from the display 18 based on the setting of the hold release state. Then, in step S9, a counter for measuring time is initialized, and the process returns to step S1.

If the hold button 12 is continuously pressed until after a predetermined time has elapsed, it is determined in step S1 that the hold button 12 has been pressed, and it is determined in step S2 that the state flag is ON. Therefore, step S
1. A loop of step S2 is held, and the hold is released.

When the hold button 12 is released after a lapse of a predetermined time, it is determined that the hold button 12 has not been pressed in step S1, the hold flag is cleared in step S3, the counter is initialized in step S9, and the step It returns to S1. For this reason, the hold release state is maintained.
