Reference numeral 40 denotes a local / DX changeover switch for switching a stop sensitivity in a seek operation. Reference numeral 41 denotes whether the display unit 11b-1 of the touch panel type data input device 11b displays only the operation state of the on-vehicle audio equipment, or operates. This is a display changeover switch for switching between displaying the state and the key image based on the high / low state of the display changeover signal IMC.

Touch panel type data input device The touch panel type data input device 11 displays an operation state image and a key image on the display unit 11b-1, and points on the surface of the display unit 11b-1 indicated by a finger or the like when displaying the key image. Are detected and output by the optical coordinate detector 11b-2. FIG. 4 is an exploded view of the touch panel data input device, and FIG. 5 is a perspective view of the touch panel data input device.

The touch panel type data input device 11 displays an operation state image and various key images for data input.
It has a display unit 11b-1 such as a CD (liquid crystal element) or a CRT, and an optical coordinate detection unit 11b-2 in which a light emitting element and a light receiving element are provided in a frame having a shape corresponding to the outer shape of the display unit. .

The optical coordinate detecting section 11b-2 includes a display unit 11b.
-1 and a frame 52 having a size corresponding to the outer shape of the display unit 11b-1, and a light emitting element is provided on each of four opposing sides of the frame. A large number of light-receiving elements 52b and light-receiving elements 52c are arranged in pairs, and the light-emitting elements 52b emit light one by one sequentially in the X direction, and then similarly emit light one by one in the Y direction. By scanning the surface and detecting the position where the light beam is blocked, the X and Y coordinate values of the point on the surface of the translucent panel 51 specified by the fingertip or the like can be detected. That is, the light-emitting element and the light-receiving element arranged on the opposite side are made to correspond to each other, the light-emitting elements are sequentially emitted one by one in the X direction, and it is checked whether the corresponding light-receiving element has received light (light is blocked). Check whether or not the light receiving element is detected in the X direction at the designated point. Then, the light receiving elements are similarly emitted one by one in the Y direction to check whether the corresponding light receiving element has received light. Thus, the coordinate value in the Y direction of the point designated by the user can be detected.

The bright overall operation daytime ambient, when the light selector switch is present in the off position, the display switching signal IMC output from the display switching signal generation unit 12 b - in the state. In such a state, the control unit 11c instructs the display control unit 11e to display the operation state, and also displays the audio source in operation and the data indicating the operation state (AM / FM, tuning frequency, stereo / monaural). , Playing / rewinding /
Etc. during fast forward). As a result, the display control unit 11e generates an operation state image of the currently operating audio source and displays it on the ideographic unit 11b-1 of the touch panel type data input device 11b (FIG. 3 shows the operation state image of the tuner). Displayed). In displaying the operation state image, the input key image identification unit 11g ignores the coordinates input from the touch panel data input device.

On the other hand, when the light changeover switch is switched to the lighting position at night or for other reasons, the illumination signal becomes high and the display changeover signal IM
C also goes high. When the display switching signal IMC becomes high,
The control unit 11c instructs the display control unit 11e to display a key image, and inputs data specifying the operating audio source to the display control unit 11e and the input key image identification unit 11g.

Thus, the display control section 11e reads out the key image corresponding to the currently operating audio source from the key image storage section 11d, and synthesizes it with a predetermined operation state image (tuning frequency or the like) as necessary. To display on the display unit 11b-1 of the touch panel type data input device 11b (FIG. 2).
(See (a) and (b)).

In this key image display state, for example, in a state where the key image of the tape deck is displayed, in order to rewind the tape, a "rewind key image" 11d-7 (FIG. 2 (b)) Is designated by a finger, the input key image identification unit 11g determines which key image display area the coordinate value is based on the coordinate value of the designated point and the key image position.
As a result, the designated key image is recognized as a "rewind key image", and key data corresponding to the rewind key image is output to the control unit 11c.

The control unit 11c includes an input key image identification unit 11g.
When key data corresponding to the rewind key is input,
The system controller 13 informs the system controller 13 via the bus line 16 and thereby controls the tape deck 14 to perform rewinding, and notifies the controller 11c of the operation panel 11 of a rewinding signal. Note that the same applies when the “play key image” 11d-8 or the “fast forward key image” 11d-9 is pressed. The above is the case where the tape deck is operating, but the same applies when the tuner is operating.

There are cases where it is desired to perform a normal key operation even at night. For this purpose, each key image is provided with a display switching key image (DISPLAY) 11d-1 and 11d-6.
A display switching key 41 is provided in 1a. During key image display, display switching key image (DISPLAY) 11d-1 or 11d-6
Is instructed, or when the display switching key 41 is pressed, the control unit 11c causes the display control unit 11e to display a normal operation state image. Also, the display switching key 41 again
Is pressed, a key image of the operating audio source is displayed.

In the above description, the touch panel type data input device 11b is provided at the center of the operation panel. However, if operability is important, it may be arranged at the right end. Although the present invention has been described with reference to the embodiments, the present invention can be variously modified in accordance with the gist of the present invention described in the claims, and the present invention does not exclude these.
