Further, a frequency/time display 7 is formed approximately in the middle of the movable display section of the tuner deck 1, and the display of the frequency/time display 7 is switched by a clock switch 8 disposed on the lower right side of the figure. Furthermore, 9 in the figure indicates volume, sound quality (
This is an adjustment mode display section that displays adjustment of selection modes such as treble, bass), fader, and balance, and the selection display lamp 10 indicates which mode is selected.

In addition, the part surrounded by the two-dot chain line in Fig. 3 is the preset switch group 11, 12 is the FM/AM changeover switch, and 13 is the preset switch group.
14 is a play program switch, and 14 is an opening/closing switch for movable display A. When this opening/closing switch 14 is pressed, movable display A slides downward and opens as shown in Fig. 5, and the internal cassette insertion slot B is visible. and,
As shown in FIG. 6, the movable display A can be switched between the closed state and the closed state by sliding in the opposite direction. Further, 15 is an eject/reload switch, 16 is a power switch, and 17-17 is an indicator indicating the rotation direction of the tape.
Reference numerals 18 and 18 are indicators indicating the running direction of the tape.

As shown in FIG. 4, this indicator 17018 is an aggregate of a plurality of fluorescent display segments (17a-17a), and has a substantially elliptical configuration. The indicator 18 is made up of a single triangular fluorescent display segment, and the indicators 17, 17 sequentially blink the fluorescent display segments 17a, 17a, etc. in accordance with the rotating direction of the expropriated cassette tape. Rotate, and
The indicator 18-18 lights up when one of the tape running directions is selected. Moreover, each fluorescent display segment 17
A or 18 uses the principle of a directly heated three-power vacuum tube, and has a filament (hot cathode), a grid, and an anode (anode segment), and thermionic electrons emitted from the filament are accelerated by the grid, and the phosphor By colliding with the anode coated with , the luminescent centers are excited and emit light. That is, the light is turned on when the grid and the anode have a positive potential with respect to the filament, and the light is turned off when the grid and/or the 7 nodes have a negative potential.

However, according to this tuner deck 1, the indicator 17Φ17 that indicates the rotational direction of the tape always flashes continuously in the same pattern, that is, it only repeats the indication of the rotational direction, and there is no time for turning the edges of a constant pattern over a long period of time. I'll come.

[Purpose of the invention]

Therefore, the present invention has been made in view of the above-mentioned circumstances, and by adding an element of play to the indicator indicating the rotation direction of the tape, the display pattern indicating the rotation direction changes each time a cassette is inserted. The purpose of the present invention is to provide a display method for an audio device that satisfies a user's taste and can increase the added value of the product by eliminating the need for special operations to switch display patterns.

[Summary of the invention]

In order to achieve this object, the display method of the audio device according to the present invention has a display section composed of a plurality of display segments, which is configured in advance to display a plurality of types of display segments in accordance with the input of media loading/unloading data. It is characterized by blinking in one of the patterns.

[Effect]

By adopting the display method described above, there is no need for special switch operations, and the display segments that make up the display part flash continuously in a different pattern each time the media such as a cassette is replaced. It satisfies the senses, never gives up, and increases the added value of the product.

〔Example〕

Next, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

The display method of the audio device in this embodiment is shown in FIG.
This is executed in the indicator 17Φ17 indicating the rotation direction of the cassette tape of the tuner deck 1 shown in FIG. 4, and FIG. 1 is a sequence block diagram of the display method. Inputs from the operation section are built into the tuner deck 1, and are sent to the microcomputer 19, which also controls the cassette tape drive section 21, playback section 22, etc., and receives the data. to finally select each fluorescent display segment (17a, 17a) of indicators 17, 17 indicating the direction of rotation of the cassette tape, and light them up in one of the patterns set in the multiple types of memory. ,
Turn off the lights. In order to obtain this display method, there is no need for the operation unit in this embodiment to require any special means such as pressing a switch, and the operation is triggered by loading and unloading the cassette tape. In addition, as for the multiple types of patterns described above, since the indicators 17, 17 indicating the rotation direction are used, they will be continuously rotating and flashing within the mission of the indicators, but specifically, the lights will turn off sequentially from normal overall lighting. In addition to patterns in which half of the lights are turned off and the position is moved with the same width, there is also a slow type in which each pattern has a temporal difference.

FIG. 2 is a flowchart showing the processing flow of this display method, in which a counter in the microcomputer 19 increments the N value by +1 as a certain period of time passes. Here, the N value is, for example, a value of O≦N≦9,
When N reaches "10" by counting +1, put O into N.

Therefore, the data on the loading and unloading of the cassette tape is stored in the drive unit 21.
When it is confirmed that the input is from the playback section 22, etc., the display pattern corresponding to the value of N at that time, that is, the combination of flashing fluorescent segments The pattern of changes made is read out from the memory, and is usually displayed on the indicator 17φ17 as a different pattern from the previous one.

Incidentally, in this embodiment, indicators 17 for the rotational direction of the cassette tape were used as the display section.

It is also possible to display certain messages such as alphabets, numbers, symbols, etc. on other displays 7, etc., and it can also be used in conjunction with a rhythm box when a performance is not in progress.

Furthermore, although this embodiment has been described using the tuner deck 1, other audio devices such as a compact display player may be used, and a liquid crystal display or the like may be used as the fluorescent display.
