Abstract

PURPOSE:To visually observe position information of a medium by displaying relatively a position confirmation at the time of loading and ejecting a contained medium by a graphic indicator. CONSTITUTION:To a microcomputer 22, a data is inputted by a key (switch group), and between these microcomputers 20, 22, no switch data is inputted in the course of loading or in the course of ejection of a compact disk. Accordingly, after a command of load/eject is sent from the microcomputer 22 to 20, a display part (especially, a rotary graphic indicator 13) varies a display by a timer until its operation is ended, and displays a state of its load/eject. In such a way, by operating the graphic indicator 13 of the display part 3, the state of load/eject of a medium can be observed visually and confirmed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a display system, particularly a display of an in-vehicle audio device, which allows the loading and ejecting status of media to be visually confirmed. Concerning display methods.

[Background of the invention]

FIG. 4 is a front view of an in-vehicle audio device, particularly a compact disc player l. In this player 1, when the open/close switch 2 is pressed, the display section 3 slides open as shown in FIG. 5, the compact disc insertion section is exposed, and the display section 3 is closed. This sliding opening/closing of the display section 3 can be automatically obtained by inputting the eject/reload switch 4. A power switch 5 is provided below the eject/reload switch 4, and the power can be turned on or off each time it is pressed. Further, 6 is a switch for fast forwarding and fast reversing. Further, in the figure of the display section 3, on the right side there is a repeat switch 7 which, when pressed while playing a compact disc, will repeat only that song. ) Scan switch to play each song 8. A music sensor switch 9aΦ9b is provided to locate the beginning of a favorite song when pressed during a performance or a pause, and a play/pause switch 10 is provided for switching between playing and stopping at -, and when 11 is pressed, a built-in computer is assembled. This is a music in cross switch that allows you to arbitrarily rearrange the song numbers and play them using a random number table.

Further, above the approximately central portion of the display section 3, a digital display 12 is provided with a track number display section 12a that automatically displays the track number when a compact disc is inserted, and an elapsed time display section 12b. Further, numeral 13 is a rotating graphic indicator that imitates the shape of a compact disc in perspective and indicates the direction of rotation of the compact disc, and numeral 14 is a remaining time indicator, which is shaped like a downward U-shape and is composed of a plurality of dot segments. The number of dots is divided into eight from the left, and the light is turned off sequentially from the left every one-eighth of the total time of the compact disc.

Moreover, FIG. 6 shows the above-mentioned rotating graphic indicator 1.
3, it is constructed by combining a plurality of display segments 15, 15, . . . displayed on a high-brightness FL tube or the like.

Here, in this compact disc player 1, while the display unit 3 is being slid open and a compact disc is being loaded or ejected,
The display on the display unit 3 is in a stationary state, making it impossible to visually confirm whether the compact disc is moving or whether it has been completely loaded or ejected.

[Purpose of the invention]

Therefore, the present invention has been made with attention to the above-mentioned actual situation, and it is possible to solve the problem and check the loading/ejecting status from above using a mechanism that allows the display section to move. The purpose of the present invention is to provide a display method that can break the static state of the display during loading/ejecting and add movement to satisfy the taste of the user and increase the added value of the product.

[Summary of the invention]

In order to achieve this object, a display system according to the present invention includes providing a graphic indicator on a slidably supported display portion to indicate the rotational state of a storage medium constituted by a plurality of display segments; The present invention is characterized in that a graphic indicator relatively displays position confirmation when loading and ejecting the storage medium.

[Effect]

By operating the graphic indicator on the display unit as described above, it is possible to visually confirm the loading/ejecting status of the media. At the same time, the static state of the display during loading/ejecting is broken and the display moves, which satisfies the user's sense of taste and increases the added value of the product.

〔Example〕

Next, an example of the implementation of the present invention will be described in detail with reference to FIGS. 1 to 3.

FIG. 1 is a block diagram of the hardware of a compact disc player in which the display method according to the present invention is executed. This is a microcomputer that controls each display section, and these two microcomputers 20 and 22 are electrically connected so that data can be sent in and out of each other. or.

Data is input to the microcomputer 22 using keys (switches). Also, switch data is not entered between the microcontrollers 20 and 22 while the compact disc is being loaded or ejected, so after a load/eject command is sent from the microcontroller 22 to the microcontroller 20, no switch data is entered between the microcontrollers 20 and 22 until the operation is completed. The display section (particularly the rotating graphic indicator 13) changes its display using a timer to display the load/eject status.

FIG. 2 is a flowchart showing the processing when loading a compact disc. First, the open/close switch 2 is pressed, the display section 3 makes a decision as to whether or not to start closing. In this case, a switch mechanism is used to detect whether or not a disc is inserted. If a disc is already inserted here,
Alternatively, if the closing of the display section 3 has been started in the previous decision, a command to load the disk is issued. When this command is issued, the timer starts, and within the time it normally takes to load, based on a fixed time length T, the display corresponding to that time length is read out from memory and rotated sequentially. When the timer reaches the end, which is displayed on the graphic indicator 13,
When a play command is issued, the play mode display format (continuous blinking of segments 15, 15, etc. representing the rotation direction) is shown.Furthermore, FIG. 3 is a flowchart showing the flow of processing at the time of ejection. , First, when it is confirmed that the eject switch 4 is turned on, a command to eject the disc is issued, a timer starts, and the display according to the time T is displayed from the memory in the same way as when loading (the direction is reversed). It is read out and displayed on the rotating graphic indicator 13.

If the disc gets stuck during ejection or loading, the rotating graphic indicator 1
The display No. 3 stops in that state, and its position etc. can be confirmed.

In addition, although this embodiment uses a timer to change the display,
It is also possible to arrange a detection means such as an optical sensor in the player 1 to detect the position of the compact disc when it is loaded/ejected, thereby displaying the position more accurately.Furthermore, this embodiment will be explained using a compact disc player as an example. However, it goes without saying that it can also be applied to loading/ejecting cassette tapes.

〔Effect of the invention〕

As described above, according to the display method of the present invention, the positional state of the media at the time of loading/ejecting can be visually confirmed in conjunction with the sliding movement of the display section. Furthermore, the display changes during loading/ejecting, which satisfies the user's hobby and increases the added value of the product.
