Abstract

PURPOSE:To improve the commercial value of an audio equipment by preparing a first display mode in which numeric display or the like are executed while a tuner is in the middle or reception or while a tape deck is in the middle of operation, and a second game display mode which is used while the tuner or the tape deck is in the middle of non-operation. CONSTITUTION:A control circuit 8 provided in the controller 11 of a display device is connected with a RAM9, a ROM10 and a key matrix 12. The keys 21-1 to 12-5 of a front panel in a deck device having the matrix 12 share the preset key of the tuner and the stop operation key of respective displays in the game mode. When a cassette is set in the tape deck 6, a tape is ejected by operating an eject key 12-6. When the tuner is not turned off, it is turned off by a key 17-7. A key 12-8 is operated in such a state, and a display 5 displays the numerics of five digits, whereby respective numerics are stopped by the sequential operation of the keys 12-1 to 12-5.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a display device that receives data such as the receiving frequency of a tuner or the running state of a tape deck and displays numbers.

[Technical background of the invention]

Synthesizer tuners and the like are constructed to display the received frequency numerically on a display, and there are also devices that use this display to display the running status of a tape deck.

FIG. 5 shows a block diagram thereof, in which 1 represents the front end of the tuner, and 2 represents the intermediate frequency amplification circuit.

The front end 1 is configured to be applied with a local signal from a PLL 3, and a programmable frequency divider or the like in this PLL 3 outputs data according to the frequency division number.
That is, the received frequency data is applied to the display driver 4. Therefore, the display driver 4 allows the display to display the frequency being received numerically.

On the other hand, when a cassette tape is loaded into the tape deck and the tuner mode is switched to the tape deck mode, an output pulse is received from the running detector 7 that detects the tape running state of the tape deck 6, and this is applied to the display driver 4.
For example, the display 5 displays an operation display that indicates that the reel shaft is rotating.

However, unless a cassette tape is loaded on the deck and the tuner is not turned on, the display itself will not function.

[Object of the Invention] The present invention has been made in view of the above-mentioned prior art, and provides a multifunctional audio device that can use the display for other functions when the deck and tuner are not turned on. This is what I am trying to do.

(Summary of the invention) In order to achieve the above-mentioned object, in this invention,
A game that has a display mode in which at least multiple digit numbers are randomly switched and displayed based on a program stored in a storage device such as a ROM, and in which the switching display operation of each digit number can be stopped using an operation key. It is characterized by its functionality.

[Examples] The present invention will be described below based on Examples. FIG. 1 is a block diagram showing an embodiment of the invention. Code 1 in the diagram
The parts indicated by 7 to 7 are the same as or equivalent to those of the conventional example shown in FIG. 5, and therefore, the explanation of the structure will be omitted.

In this embodiment, a control circuit 8 is further provided,
A RAM 9 and a ROM 10 are connected to the control circuit 8, and each of these elements indicated by reference numerals 4, 8 to 10 constitutes a controller 11. A key matrix 12 is connected to this controller 11.

The key matrix 12 is arranged in the lower half of the front panel as shown in FIG. It is designed to also serve as an operation key for stopping the display of each number in a game mode to be described later.

FIG. 3 is a flowchart showing the operations performed by the controller 11 described above, and particularly shows the game mode.

That is, first, it is confirmed that no cassette tape is loaded in the tape deck 6 (step 1). If a tape is loaded, press the eject key 12-6.
Operate to eject the tape (step 2). Next, it is determined whether the tuner is off (step 3). If it is not off, the tuner is also turned off by operating key 12-7 (step 4). When the key 12-8 is operated (step 5), the display 5 starts lighting up the 5-digit numbers, that is, X, ~χ5, and the segment numbers that make up each digit (step 6). The numbers are randomly switched and displayed (step 7).

Here, it is determined whether the stop key 12-1 has been pressed (step 8), and if it has been pressed, the first digit number stops (step 9). Next, it is determined whether the stop key 12-2 has been pressed (step 10), and if it has been pressed, the second digit number stops (step 11). Furthermore, stop key 12-
It is determined whether 3 has been pressed (step 12), and if it has been pressed, the third digit number stops (step 13). Similarly, the fourth and fifth digits are stopped by the stop keys 12-4 and 12-5 (steps 14 to 17).

If you do not press any of the stop keys 12-1 to 12-5, the timer will start counting (
Step 18), and when 3 seconds or more elapse, for example, the number of time overs is set to N=O (Step 19), and then N
is incremented (step 20). Then, it is determined whether the incremented N value satisfies 3 (step 21), and if it does not, a 5-digit number is displayed on the display 5 with the numbers of each digit not matching (step 2).
2) Do. In this way, the process returns to step 2o, and when the N value matches 3, that is, when repeating 3 times, the display of each 5-digit number is automatically changed to the same value (for example, 3°3, 3, 3, 3).
) and the display change is stopped (step 23).

On the other hand, after passing through step 17, it is determined whether all of the five digits match (step 24). If they do not match, the process returns to step 6 and continues the same operation again. If all the numbers match, step 23
A routine similar to the above is entered, and a demonstration mode is started (step 25).

In this demonstration mode, as shown in FIG. " is displayed. Thereafter, the central segment of the display 5 is illuminated as shown as C, and then the four segments as shown as D are illuminated. Further, eight segments 1- are lit as shown as E, and after these operations C-E are quickly repeated about 10 times, a display as shown as F is obtained.

(Step 26) After passing through the above series of operations, the process returns to step 6 and is repeated until the operation key 12-8 is operated.

〔effect〕

As described above, the present invention provides a first display mode in which numbers are displayed while the tuner is receiving data or a tape deck is in operation, and a second game display mode that can be used while the tuner or tape deck is not in operation. , the display can be used for multiple functions and the product value can be improved.
