Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a display mode at the time of power-on of an audio visual apparatus with a timer function.
[0002]
[Problems to be solved by the invention]
Some audio-visual devices have a timer function, and such an audio-visual device has a built-in clock so that the current time can be displayed. A device with a large display or multiple displays can have a dedicated display area for displaying the current time (clock), so the clock is displayed regardless of the operation mode, such as when the power is turned on or off. Can do.
[0003]
However, an audio-visual device with only a small display will display information about the audio-visual source, such as the CD track number and elapsed time, and the band and frequency of the broadcast being received, while the device is in operation. The current time cannot be displayed.
[0004]
When using an ordinary audio-visual device, the user will not feel much inconvenience even if there is no clock display. However, when using the audio-visual device as a wake-up timer, the timer function turns on the power. When this happens, the clock display disappears and the display changes to the audio / visual source information display, so that the user who wakes up cannot check the current time. Even with such an audio-visual device, the display on the display can be switched to a clock display if a predetermined operation is performed, but it is extremely troublesome to wake up such an operation.
[0005]
An object of the present invention is to provide an audio-visual device with a timer function that can display the current time on a small display even when the power of the device is turned on by a timer.
[0006]
[Means for Solving the Problems]
The present invention provides a reproducing means for reproducing an audio-visual source, a power switch for turning on / off the reproducing means, a display means, and the reproducing means when the power switch is operated or when a predetermined on time arrives. An audio-visual device with a timer function comprising:
The control means displays the current time on the display means during standby before the on-time arrives, and displays audio / visual source information on the display means when the playback means is activated in response to an operation of a power switch. When the on-time comes and the playback means is activated, the display means displays the current time and part of the audio-visual source information in parallel.
According to the present invention, when the control means displays the current time and a part of the audio / visual source information in parallel on the display means after the ON time has arrived, the control means corresponds to a predetermined release operation. The display means switches to displaying only the audio / visual source information.
[0007]
The present invention is an invention that should be applied to an audio-visual device having a display means that is so small that the current time (clock) and audio-visual source information cannot be displayed together. When the power is on, the current time is displayed on the display means, and the audio / visual source information is displayed when the power is turned on in the normal mode. Here, the audio-visual device in the present invention is a concept including both an audio source and a device that can reproduce both the visual source and a device that can reproduce only one of the audio source or the visual source, and the audio-visual source. The information includes, for example, CD track number and elapsed time, DVD chapter number and elapsed time, received broadcast band (AM, FM, TV, etc.) and frequency.
On the other hand, when the on-time comes and the power is turned on by the timer function, it is necessary to display the information of the audio / visual source to be played back, and to inform the user of the current time at the same time . Therefore, the current time is displayed, and a part of the audio / visual source information is displayed within a range that can be displayed by the display means. The audio / visual source information includes, for example, only a track number in the case of a CD and only a band in the case of broadcasting. As a result, the user who uses the timer function as an alarm can be notified of the current time and the information of the audio-visual source being reproduced at that time.
Further, by shifting to the normal mode with a predetermined release operation, there is no trouble in subsequent normal use.

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 FL display 11 is a small display composed of a 12-digit character display.
[0009]
The main controls are a power switch 12 for switching the operation of the apparatus to the standby state / on state, an open / close switch 13 for opening / closing the CD tray, a timer switch 14 for setting / releasing the timer operation, and an FL display. A display switch 15 for switching display contents, an input switch 16 for switching audio sources, and the like. The power switch 12 does not turn on / off the power supply of the apparatus by hardware, but an audio playback function such as CD playback or FM broadcast reception (the signal processing circuit unit 4, the servo control circuit unit 5, etc. in FIG. 2). ) Is turned on / off, and the CPU 1 (see FIG. 2), which is the control unit of the apparatus, operates regardless of whether the switch is turned on / off. 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.
[0010]
This CD receiver device can adjust the current time and set the timer on time by a predetermined operation. The set ON time is stored in the EEPROM 7 (see FIG. 2). When the timer switch 14 is turned on to enter the timer mode and then the power is turned off by the power switch 12, the timer mode enters a standby state and the timer function operation (timer operation) is executed. In the timer mode, the power is turned on when the on-time comes, and the audio source previously selected by the input selector switch 16 is reproduced. The timer mode is valid until the timer mode is released. When the display switch 15 is turned on, the timer mode is canceled and the normal mode is entered.
[0011]
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 uses the timer function to wake up can sleep for an extra 5 minutes by pressing the snooze button. The FL display 11 displays the current time when the power is off (see FIG. 4C), and displays audio source information when the power is on in the normal mode (see FIG. 4B). On the other hand, while the power is turned on in the timer mode, the current time and the audio source information are displayed in parallel (see FIG. 4A). However, since the FL display 11 is a 12-digit compact one, the audio source information displayed in parallel with the current time is simple.
[0012]
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 based on the time of the clock in the timer mode. The EEPROM 7 stores the on-time of the timer.
[0013]
The operation of the CD receiver will be described with reference to the flowchart of FIG. 3 and the display example of FIG.
FIG. 3 is a flowchart showing the display control operation in the timer mode. This process is repeatedly executed at predetermined intervals. Until the on-time of the timer arrives, the current time is displayed on the FL display 11 as shown in FIG. 4C by the determination of s1 and s2 (s7: standby display). Thereafter, when the on-time of the timer comes, playback of the audio source is started (in this embodiment, CD playback is started), and the display on the FL display 11 is shown in FIG. The current time and audio source information are displayed (s5).
[0014]
The display of this audio source is simple. That is, for example, during CD playback, in the normal mode, the track number and the elapsed time are displayed as shown in FIG. 4B, but only the track number is displayed in parallel display with the current time in the timer mode. To do.
[0015]
After the on-time has arrived, the process proceeds to s3 and s4 based on the determination of s1 and s2, but the current time of s5 and the audio source information are displayed in parallel until the user cancels the timer mode. After the user performs the release operation, the audio source information (see FIG. 4B) that is normal power-on display is displayed on the FL display 11 based on the determination of s4 and s3 (s6). When the power is turned off regardless of the timer mode or the normal mode, the display shifts to the standby display (s7) based on the determination of s2.
[0016]
Here, the timer mode can be canceled by turning on the display switch 15. However, other than this, the timer mode may be automatically canceled by an audio source changing operation such as opening the lid of the CD tray 10, for example. Good.
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 by a timer function.
[0017]
【The invention's effect】
As described above, according to the present invention, when the audio-visual device is turned on by the timer function, the timer function is used as an alarm clock by displaying a clock together with a part of the audio-visual source information. The current time can be notified to the user who is present, and the clock can be used instead. Furthermore, since all the audio / visual source information is displayed in the normal mode, the use as an audio / visual apparatus is not hindered.
