DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is an external view showing an upper surface of a CD receiver device according to an embodiment of the present invention. On the top surface, a CD tray 10 on which an audio CD is set, an FL display 11 for displaying audio source information and time, and a number of operators are provided. The main controls are a power switch 12 for switching the operation of the apparatus to standby / on, an open / close switch 13 for opening / closing the CD tray, a timer switch 14 for setting / releasing the timer operation, and display contents of the FL display. A display switch 15 for switching the audio source, an input switch 16 for switching the audio source, and the like. The power switch 12 is a switch for turning on / off an audio playback function such as CD playback or FM broadcast reception instead of turning on / off the power of the apparatus in hardware. Regardless, the CPU 1 (see FIG. 2), which is the control unit of the apparatus, is operating. In this description, turning on the audio playback function is called power-on, and turning off the audio playback function (standby) is called power-off.
[0017]
This CD receiver device can adjust the current time and set the on time and off time of the timer by a predetermined operation. The set on time and off time are stored in the EEPROM 7 (see FIG. 2). When the timer switch 14 is turned on when the power is off (standby), the timer mode is set and the timer function operation (timer operation) is executed. In the timer mode, the power is turned on at the on time, and the audio source previously selected by the input selector switch 16 is reproduced. At the off time, the power is turned off and the playback of the audio source is stopped. Further, when a predetermined operation is performed in the timer mode, the timer mode is automatically canceled according to this operation. This operation will be described in detail later.
[0018]
On the other hand, when the power is turned on by the timer function (operating in the timer mode), the input selector switch 16 functions as a snooze button. That is, when the user turns on the input switch 16 after the power is turned on by the timer function, the apparatus interrupts the reproduction for a predetermined time (5 minutes) and resumes the reproduction after the predetermined time. As a result, the user who is using the timer function to wake up can sleep for an extra 5 minutes by pressing the snooze button.
[0019]
FIG. 2 is a block diagram of the CD receiver apparatus. A user operation unit 2, a mechanical mechanism unit 3, a signal processing electronic circuit unit 4, a servo control circuit unit 5, a display 6 and an EEPROM 7 are connected to the CPU 1 that controls the functions of the apparatus. The user operation unit 2 includes various switches such as the power switch 12, the open / close switch 13, the timer switch 14, the display switch 15, and the input changeover switch 16 described with reference to FIG. 1. The mechanical mechanism unit 3 includes a mechanism for opening and closing the lid of the CD tray 10. The signal processing electronic circuit unit 4 includes electronic circuits such as receiving FM broadcasts and amplifying audio signals. The servo control circuit 5 is a circuit that controls the rotation of the CD and the driving of the head. Further, the CPU 1 has a built-in clock 6 and controls the power on / off based on the time of the clock in the timer mode. The EEPROM 7 stores the on time and off time of the timer.
[0020]
The operation of the CD receiver device will be described with reference to the flowcharts of FIGS. 3 and 5 and the timing chart of FIG.
FIG. 3 is a flowchart showing the operation in the timer mode. Since the timer mode is set when the power is turned off, this operation starts while the power is turned off. While the power is off, the built-in clock is on standby until the preset on time is reached (Sa6).
[0021]
When the CD tray 10 is opened / closed by operating the open / close switch 13 for opening / closing the CD tray during the power-off standby (Sa1), an open detection flag is set (Sa2). When the CD tray is opened, the power is automatically turned on even when the power is off, and the operation proceeds from Sa2 to Sa3 and Sa5. Note that the process proceeds to Sa5 even when the power is turned on not by operating the open / close switch 13 but by operating the power switch 12. However, at this time, the open detection flag is not set. Thereafter, when the power is turned off by the operation of the power switch 12 until the on time is reached (Sa5), the open detection flag is reset (Sa4), and the process waits until the on time is reached (Sa6).
[0022]
When the on-time arrives in the power-off state and the process proceeds from Sa6 to Sa7, power-on processing such as register reset is executed (Sa7), and audio source reproduction (CD reproduction in this case) is started (Sa8). And it waits until an off time comes (Sa12).
[0023]
When the CD tray 10 is opened / closed by operating the open / close switch 13 while the power is on (Sa9), an open detection flag is set (Sa10). After that, if the power is turned off by operating the power switch 12 (Sa11) by the time of turning off (Sa12), it is not necessary to start the off timer, and the timer mode operation is terminated as it is.
[0024]
On the other hand, if the on-time has arrived with the power on, the process at the time of power-on (Sa7, Sa8) is skipped in the determination of Sa5 and the process proceeds to Sa9 and subsequent processes.
[0025]
When the off time has arrived with the power turned on (Sa12), it is determined whether or not the open detection flag is set (Sa13). If the open detection flag is not set, the timer mode is set. Is executed (Sa15), and the operation is terminated. On the other hand, when the open detection flag is set, the timer mode is canceled without turning off the power (Sa14), and the processing operation is shifted to the normal mode.
[0026]
The timer mode is set when the power is turned off, and if the CD tray is not opened after that, the power is turned on at the on time and the power is turned off at the off time. The However, the set time is not cleared.
[0027]
In the CD receiver device of this embodiment, the power is automatically turned on when the CD tray is opened while the power is off. However, the CD tray may be opened and closed while the power is off. The opening / closing of the CD tray may be permitted after the power is turned on in advance.
[0028]
The operation of the timer mode described in the above flowchart will be described with reference to the timing chart of FIG. First, the case of FIG. If the timer mode is set while the power is off, and the active state change operation such as opening / closing the CD tray is not performed, the power is turned on at the on time, and the power is turned off at the off time to cancel the timer mode. .
In the case of FIG. 5B: Even when the CD tray is opened and closed during standby, if the power is turned off by the on time thereafter, as in the case of FIG. The power is turned on at the on time and the power is turned off at the off time to cancel the timer mode.
[0029]
In the case of (C) in the figure: the open detection flag remains set when the CD tray is opened and closed during standby and the on time arrives while the power is on. Then, only the timer mode is canceled without turning off the power, and the operation moves to the normal mode.
Case (D): Even if the power is turned on at the on time in the normal timer mode operation, the open detection flag is set and the off time is set when the CD tray is opened and closed during the on operation. Even if the error occurs, only the timer mode is canceled without turning off the power, and the operation moves to the normal mode.
[0030]
FIG. 5 is a flowchart showing the snooze function in the timer mode. Since the snooze function is a function of an alarm clock as described above, the timer mode will be described as an alarm function in this flowchart. Since the timer mode is set when the power is turned off, this operation starts while the power is turned off. Waiting until the on-time is reached in the power-off state (Sb2). When the power is turned on during the power-off standby (Sb1) and the on-time is reached as it is, the timer mode, which is a wake-up function, is canceled (Sb8), and the process proceeds to normal mode processing.
[0031]
When the on-time comes in the power-off state (Sb2: this state includes the case where the power is turned on once during the power-off standby and the power is turned off by the on-time). A power-on process is executed (Sb4), and an alarming operation for starting playback of an audio source (here, playback of a CD) is executed (Sb5). At this time, the function of the snooze button is assigned to the input selector switch 16. Thereafter, if no operation is performed, the operation in the wake-up mode is continued as it is. The wake-up mode is a state in which the power is turned on in the timer mode when the on-time comes and the timer mode is continued as it is. During the alarm mode, the input selector switch 16 functions as a snooze button.
[0032]
If a tray opening / closing operation is detected during the wake-up mode (Sb6), the wake-up mode is canceled (Sb8) and the operation proceeds to the normal mode. The release of the wake-up mode includes a process of returning the function of the input selector switch 16 from the snooze button to the original audio input switching function. If the power is turned off during the alarm mode (Sb7), the power is turned off (the alarm mode is canceled at this time).
[0033]
On the other hand, when the snooze button (input changeover switch) is turned on during the alarm mode (Sb12), the snooze operation is started (Sb13). The snooze operation is an operation for stopping the reproduction of the CD for a predetermined time (in this embodiment, 5 minutes). That is, it is a mode for sleeping for 5 minutes after the wake-up operation is started, and a 5-minute interruption timer is started. When this timer counts 5 minutes, the interruption of the CD reproduction is canceled by the determination of Sb9 and Sb10, and the reproduction of the CD is resumed (Sb11). Even when the reproduction is interrupted, when the tray is opened and closed (Sb6), the wake-up mode is canceled as in the wake-up operation, and the process proceeds to normal processing (Sb8). When the switch is turned off (Sb7), the alarm mode is canceled and the power is turned off.
[0034]
The determination of the opening / closing operation of the CD tray shown in Sa1, Sa9, Sb6, etc. may be made as YES when the tray is opened and then closed, or only when the tray is opened. You may make it judge.
[0035]
In this embodiment, the timer mode is canceled when the opening / closing of the CD tray for exchanging the CD is detected. However, the operation of the user who determines that the timer mode is no longer necessary is the opening / closing of the CD tray. The operation is not limited and may be an operation such as input switching (in this case, it is preferable not to use the input switch as a snooze button). The timer mode may be canceled by an operation other than changing the audio source.
[0036]
Note that even during the operation in the timer mode shown in FIGS. 3 and 5, the timer mode can be operated only to cancel the timer mode by operating the timer switch 14.
[0037]
In this embodiment, the CD receiver device for reproducing an audio source has been described. However, the present invention can be applied to any device for reproducing an audio source or a visual source.
[0038]
【Effect of the invention】
According to the present invention as described above, for which to release the timer mode in response to audio Oso over scan changing operation by the user, the user without a special operation of canceling the timer mode also can be released only in the timer mode operations to be reproduced different audio Oso over scan the audio Oso over scan that was set at that time, it is possible to simplify the operation, use the device It is possible to perform an operation reflecting the intention of the person.
