Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a preset memory for a reproducing device that can immediately retrieve and reproduce desired reproduction signals from a plurality of external input devices connected to the audio reproducing device.

[Prior Art] Among sound reproducing devices equipped with a radio receiver, there are some that can receive traffic information broadcasts, especially those for in-vehicle use. Examples of traffic information broadcasts include roadside broadcasts and ARI broadcasts (Automobil Radio).
If the radio receiver is preset in memory with these traffic information broadcast modes, when the traffic information broadcast starts, the SK signal or DK signal transmitted at the same time will be displayed.
A pilot signal such as a traffic signal is detected, and the reproduction sound of traffic information is preferentially interrupted and reproduced from the cassette tape or other radio broadcast that is being reproduced.

[Problem to be solved by the invention] Because traffic information broadcasting is urgent in nature, the reception function preset in the radio receiver automatically switches to give top priority to all other program source playback modes. It is configured so that

By the way, the radio receiver generally does not automatically return to the program source desired by the listener unless the traffic information broadcast ends. Therefore,
If you wish to play another program source after recognizing one set of traffic information, you must cancel the preset for traffic information reception and reselect the function switch. There was an inconvenience that the operation was complicated.

Therefore, the present invention has developed a top-priority preset memory that allows a desired program source to be recalled instantly with a single operation while receiving traffic information broadcasts or playing other program sources. The purpose is to provide

[Means for Solving the Problems] In order to solve the above-mentioned problems, the playback device according to the present invention includes a highest priority mode memory that can be written and read freely for specifying a preset playback priority order for an external input device; and a top priority mode key for operating writing/reading of the top priority mode memory.

[Function] The preset memory of the playback device of the present invention specifies presets to determine playback priority for desired program sources, and by calling this preset memory, the desired program is given priority over all program sources. The source will be played immediately.

[Example] Hereinafter, the present invention will be explained based on the drawings.

Fig. 1 is a block diagram of the audio reproduction device.
A receiving section 3 and an electronic tuner system section 4 are included. The tuner 1 also has a function of receiving traffic information broadcasts preferentially.

8 is a compact disk player, 9 is a DAT,
7 is a cassette player provided integrally with the playback device, and these are the tuner section 1 of the radio.
In addition, as an external input device of the reproduction device, an output signal is appropriately selected and reproduced. Hereinafter, these external input devices will be referred to as program sources.

10 is a signal switching circuit that selectively switches the output signal of the program source, 11 is a volume control that adjusts the volume of the signal, 12 is an amplifier, 13 is a speaker, and 14 is a CPU that controls the operation of each part of the playback device. . Reference numeral 15 denotes a display section that displays the operating status of each section; for example, when the power of the playback device is off, the time is displayed, and in the radio reception mode, the reception frequency is displayed.

Next, 16 is a preset operation section, which is composed of two push buttons, namely, a top priority mode key 16a and a mode selection key 16b. The top priority mode key 16a is an operation key provided for calling and playing a desired program source with top priority.If the compact disc player 8 is designated in advance as the top priority mode, the playback device will
Even when playing in other modes such as the DAT 9, cassette player 7, or radio traffic information broadcast reception mode, playback on the compact disc player 8 can be directly executed by operating this key 16a. It becomes possible.

The designation of the highest priority mode is written and set in the highest priority memory 17 by pressing and holding the operation key 16a for, for example, 1.5 seconds or more during playback of a desired program source. Also, while playing another program source, press the operation key 16 again.
If you hold down a for more than 1.5 seconds, that program source will be set to the highest priority mode and will be transferred to the highest priority memory 17.
The contents of will be rewritten.

The mode selection key 16b is an operation key for specifying the next priority mode, and calls and reproduces the program source that was selected before the highest priority mode was specified. The mode memory 18 is a memory that stores the designation of the next priority for this purpose, and each time the contents of the above-mentioned top priority memory 17 are rewritten to a new mode, the contents of the top priority memory 17 are automatically moved down, and the mode memory Written in 18.

Note that when operating the top priority mode key 16a to specify the top priority, that is, writing to the memory 17, it is necessary to hold down the operation key 16a for 1.5 seconds or more, but for reading, the press operation must be performed within 1.5 seconds. limited to. In other words, the highest priority program source can be called up with a single touch operation. Similarly, when the next priority mode is called up by operating the mode selection key 16b, a one-touch operation is sufficient.

Next, 19 is the last channel memory, and FM
Regardless of whether the receiving section 2 or the AM receiving section 3 is receiving broadcasts, the memory stores the receiving channel that was last received before the switching operation of the signal switching circuit 10 is performed, and by operating operation keys (not shown). However, if tuner mode is specified for the above-mentioned top priority memory 17, the contents of the top priority memory 17 and last channel memory 19 will be recalled by the calling operation of the top priority mode key 16a. read simultaneously.

Next, the operation of the present invention will be explained.

Although the drawing shows only the main parts of the present invention, like other playback devices, operation switches for various parts not shown are provided, and it is possible to control the playback device by operating a group of these switches. be.

At present, the audio signals of each program source are input to the signal switching circuit 10, and a desired program source is selected by operating a function switching switch (not shown) for selecting a program source. Based on this instruction, the CPU 14 operates the signal switching circuit 10 to reproduce the desired program source. Then, the reproduction signal of the selected program source is reproduced from the speaker 13 through the amplifier 12.

Give top priority to the program source selected here.
If you want to preset the next priority mode and make settings for directly calling these program sources from now on, operate the highest priority mode key 16a twice. In other words, the first designated program source is moved down by the later designated program source, and becomes the next priority.

The contents of the set memories 17 and 18 are always backed up and maintained in this state unless rewritten thereafter.

Note that even if the playback device selects the tuner mode and traffic information broadcasting is being received preferentially, pressing either key 16a or 16 of the operation unit 16
If b is operated, the desired program source is immediately selected.

[Effects of the invention] As explained above, according to the playback device of the present invention, there is a top priority mode memory that can be written and read freely for specifying a preset playback priority order for an external input device, and the top priority mode memory. A top-priority mode key is provided to operate the writing/reading of the listener, so the program source desired by the listener can be selected instantly with a single operation, and is freed from complicated operations, especially when used with in-vehicle playback devices. , the effect is great.
