[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention accommodates a plurality of disc-shaped recording media, for example, optical discs in a predetermined array form, and selectively outputs an information signal to one of the plural optical discs. A character display area, which is mounted on a recording and / or reproducing apparatus for performing recording and / or reproducing of, displays at least the attributes such as the numbers and titles of optical discs that are symmetrical to record and / or reproduce information signals. The present invention is suitable for use as a display device for a vehicle-mounted audio set, in particular.

Further, according to the present invention, there is provided a reproducing apparatus which reproduces an information signal from the optical disc and outputs a sound from a plurality of speakers, and an acoustic listening position in which a phase of the sound output from the plurality of speakers is selected. Character display that is mounted on an audio device equipped with a sound field control device (sound field processor) that matches the above, and at least the attributes such as the number and title of an optical disc that is symmetrical with respect to recording and / or reproducing of information signals are displayed as characters. The present invention relates to a display device having a region, and is particularly suitable for use as a display device of an on-vehicle audio set.

[0003]

2. Description of the Related Art Recently, in-vehicle audio sets have been equipped with a cassette deck, a tuner, a reproducing device for optical discs, etc., and have become multifunctional. In particular, a reproducing apparatus for optical discs has a magazine in which a plurality of optical discs can be loaded, and a so-called changer, which is capable of selectively reproducing a plurality of optical discs loaded in the magazine, is mainstream. Is coming.

As an example of a magazine of this changer, as shown in FIG. 6, when a magazine 101 capable of loading six optical discs D is taken as an example, the six optical discs D are horizontally arranged on their respective plate surfaces. It is designed so that it can be loaded in a stacked state with a space between each other in the vertical direction.

Various operation keys are arranged on the operation panel for performing the reproduction operation of the changer, and the number and title of the optical disk D selected by the operation of these operation keys are displayed in characters, for example, on a liquid crystal display or the like. A configured display plate is provided, and it is possible to confirm which optical disk D is currently selected by visually checking the number or title displayed in the display area of this display plate.

FIG. 7 shows an example of a display form displayed in the display area of a conventional display plate. In this display mode, a number M of marks M corresponding to the number of optical discs D loaded in the changer magazine 101 are displayed, for example, in the form of being arranged in a row in the horizontal direction in the upper part of the display area.
A serial number is attached to each mark M so that the number of loaded sheets can be easily confirmed.

If, for example, four optical disks D are loaded in the magazine 101 without loading all six optical disks D, the number not loaded in the number attached to the mark M The corresponding number is turned off and displayed so that the loading state of the optical disc D loaded in the magazine 101 can be easily confirmed.

[0008]

The display form of the marks M displayed on the conventional display plate does not match the array form of the optical discs D loaded in the magazine 101 of the changer. For example, as shown in FIG. 6, even for a magazine 101 in which six optical discs D can be vertically stacked and loaded, the form displayed in the display area of the display plate is as shown in FIG. The number of marks M corresponding to the number of optical disks D loaded in the changer.
Are arranged in a row in the horizontal direction.

In this case, for example, the fourth optical disc D
And the mark M with the number “4” are numerically identical. Therefore, in order to confirm what number of the optical disc D is currently being reproduced, it is necessary to judge by the number or title displayed in characters, and it is possible to intuitively know which optical disc D is being reproduced. There was a problem that I could not.

Although there is no problem in using the changer in a room or the like, in the situation of driving a car, for example, what number of the optical disc D is currently being played back is determined. If you have to check the display plate while looking at it again, the operation of the changer will be very troublesome, and as a result, the frequency of use of the changer will decrease and the willingness to purchase for the vehicle changer will decrease. Occurs.

Further, in an audio device (that is, a car audio system) including the above changer or the like installed in the present vehicle interior, a wide acoustic space is created in a narrow vehicle interior by controlling reverberation sound, and a 4-channel speaker is used. It is designed to incorporate a sound field processor that can improve the localization of the sound image by adjusting the output volume balance and the phase delay of the audio output.

In particular, in the sound field processor, the improvement of the sound image localization by adjusting the volume balance output from the four-channel speaker and the phase delay of the sound output is usually set at the center of the four seats in the passenger compartment. .
However, at present, it is possible to improve the localization of the sound image at the selected seat position by selecting the listening position (seat position). That is, the phase of the audio output from the 4-channel speaker is adapted to the selected seat position.

In this case, the seat position is selected by operating, for example, a numeric key on the operation panel. There is no direct correlation between the seat position and the number, and in practice, the operator generally remembers and operates the number corresponding to the seat position.

Therefore, even when operating the sound field processor, it is not possible to intuitively know the seat position for which the sound field is desired to be controlled, and it is also possible to intuitively determine which seat position is currently subject to sound field control. There is a problem that the operation of the sound field processor is substantially troublesome because it cannot be known.

In order to solve this, for example, marks for imagining a seat (hereinafter simply referred to as a seat mark) are arranged in two rows and two columns, and a display similar to the arrangement of the seats in the vehicle is displayed. Based on the display of the sheet mark in the column,
A method of setting the seat position can be considered.
However, since the on-vehicle audio device is installed in a narrow vehicle compartment, the size of the operation panel is restricted, and at the same time, the display area of the display plate provided on the operation panel is small in accordance with the operation panel. It is set.

Therefore, in the narrow display area of the display plate, the number and title of the optical disk used for operating the changer, a plurality of marks indicating the loading state of the optical disk D, and two rows and two columns used for operating the sound field processor are set. It is physically impossible to display all the four sheet marks arranged, and even if they can be displayed, each display size becomes small, which is very difficult to see.

The present invention has been made in view of the above problems, and an object of the present invention is, when applied to a device for selectively reproducing a plurality of optical disks, a so-called changer, for example, it is currently reproduced. It is possible to intuitively know what number of optical disks the currently installed optical disk is,
An object of the present invention is to provide a display device capable of improving the utilization rate of a changer in a vehicle compartment.

Another object of the present invention, when applied to a device for selectively reproducing four optical disks, a so-called four-disk changer, is, for example, what number of optical disk is currently being reproduced. It is an object of the present invention to provide a display device capable of intuitively knowing the above and improving the utilization rate of the changer in the vehicle interior.

Another object of the present invention, when applied to an audio apparatus equipped with the above-mentioned four-disc changer and sound field control device, is to intuitively determine, for example, which optical disc is currently being reproduced. In addition to the above, it is possible to intuitively know the seat position that is currently the target of sound image localization, and to provide a display device that can improve the utilization rate of the acoustic device in the vehicle interior. To do.

Another object of the present invention is to make it possible to share an operation screen used for operating the four-sheet changer and an operation screen used for operating the sound field control device, thereby providing a narrow display. An object of the present invention is to provide a display device that can effectively display the above-mentioned two types of operation screens in an area.
