Screw holes necessary for mounting the apparatus body at a predetermined position in a vehicle compartment of an automobile are provided on the side surface of the box 1. 2 are formed. Reference numeral 3 denotes a bottom plate that covers the lower opening of the housing 1, and 4 denotes a lid plate that covers the upper opening of the housing 1.
In the housing 1, a circuit such as a radio receiving circuit and a deck control circuit and a mechanism such as a cassette deck are housed. 5
Is a front member slidably supported on the front surface of the housing 1. Various operation switches 6, 7 are provided on the left and right sides of the front surface of the front member 5, as shown in FIG. Reference numeral 6a denotes a switch for switching the display of the liquid crystal display device 9. Reference numeral 8 denotes a concave portion formed at the center of the front surface of the front member 5, and a liquid crystal display device 9 is accommodated in the concave portion 8.
The liquid crystal display device 9 displays a reception frequency and the like when the radio receiver is operating, displays a track number and a playing time when the CD player is operating, a running direction and a reproduction when the cassette deck is operating. Display screen, operation mode, etc. Further, the present embodiment has a clock function, and the liquid crystal display device has the present time, date,
Can display a calendar. Pins 10 are formed on both side surfaces of the front member 5, and arc-shaped grooves for guiding the pins 10 are formed on the inner walls of the left and right protrusions 1 a and 1 b on the front surface of the housing 1. . Reference numeral 15A denotes a distal end of a sliding plate 15 slidably supported by the bottom plate 3 in the housing 1. The distal end 15A of the sliding plate 15 is connected to a lower portion of the front member 5 by a bolt 12. Have been. When the drive mechanism provided in the housing 1 operates and the slide plate 15 moves forward, the lower part of the front member 5 connected to the tip 15A of the slide plate 15 is pushed forward. For this reason, the front member 5
The pins 10 formed on the right and left sides of the upper part are guided by the grooves of the protruding parts 1a and 1b, and are slid as shown by a two-dot chain line in FIG. 13 is opened and a cassette can be inserted. When the sliding plate 15 is pulled into the housing 1 by the drive mechanism, the inclined front member 5 is slid to an upright state, and the cassette insertion slot 13 is closed by the front member 5. It is. Reference numeral 6b denotes a function switch 6b provided near the cassette insertion slot. By operating this function switch, a clock display and a calendar display can be performed on the liquid crystal display device 9.

FIG. 3 shows a control circuit for controlling the display of the liquid crystal display device 9. In FIG. 3, 9 is the liquid crystal display device, 6a is the switch, 16 is an AM / FM tuner, 17 is a CD player connected to the audio device of the present embodiment, and 18 is a cassette deck.
6. The CD player 17 and the cassette deck 18 are controlled by a control circuit 19 composed of a microcomputer or the like. The control circuit 19 is a device selection function for selecting the device in response to inputs from the switches 6 and 7 and the like, an operation control function for controlling various operations of the selected device, and an operation state of the selected device for the liquid crystal display device. 9 has a function of outputting a command to be displayed on the display 9 and a function of clocking the current time. Reference numeral 20 denotes a display control circuit that controls the display of the liquid crystal display device 9 by various commands output from the control circuit 19, and the display control circuit 20 is configured by a microcomputer or the like. The display control circuit 20
Responds to a command from the control circuit 19, and
A display control function for selecting data such as characters, colors, and numeric characters to be displayed in the RAM and setting the data in the RAM to control the liquid crystal display device 9; a time zone determination function for determining the time zone of the current time measured by the clock function; Having. 21 is a character generator.

Next, the display control processing of the above embodiment will be described with reference to FIG. FIG. 4 shows a process of changing the background color (back color) of the operation state display displayed on the liquid crystal display device 9 when the tuner 16 is operating, when the CD player 17 is operating, or when the cassette player is operating. When the switch 6a shown in FIG. 1 is continuously pressed for a predetermined time (for example, 2 seconds), the processing shifts to the processing shown in FIG. 4, and the control circuit 19 sends a back color select command to the display control circuit 20. In step A, the display control circuit 20
It is determined whether a back color select command has been received from the CPU. If it is determined that the back color select command has been received, the current mode stored in the current mode register is determined in step B to determine the tuner mode. If the current mode is determined to be the tuner mode in step B, the next back color data is set in the tuner mode color storage area of the RAM in step C. For example, if the current back color data is set to yellow data, in step C, the yellow data is rewritten to green data. Therefore, the liquid crystal display device 9
Is changed from yellow to green. When step C ends, this process ends. If it is determined in step B that the current mode is not the tuner mode, the process proceeds to step D, where it is determined whether the current mode is the CD mode.
If it is determined in step D that the current mode is the CD mode, step E
In step D, the current color data (for example, blue data) stored in the CD mode color storage area is rewritten with the next back color data (for example, black data).
If it is determined in step S that the current mode is not the CD mode, the flow advances to step F to determine whether the current mode is the cassette tape mode.
If "Yes" is determined, the color data in the cassette tape mode color storage area of the RAM is rewritten to the next color data in step G. The change of the back color in the tuner mode, CD mode and tape mode is shown in FIG. Each time the processing shown is performed, the data is sequentially changed in the order of yellow data → green data → blue data → black data → yellow data →... By pressing the button 6a for a predetermined time or more, the background color of each mode displayed on the liquid crystal display device 9 can be changed. Can be immediately recognized, and the background color can be easily changed by operating the switch 6a.

FIG. 5 is a diagram showing a display character and color data changing process in the clock mode of the present embodiment.
When the function switch 6b in FIG. 1 is operated, the mode is changed to the clock mode, and the liquid crystal display device 9 displays the data in FIG.
Characters (characters such as the sun and stars), the current time, the date, the day of the week, and the like are displayed as shown in FIG.
The display color, background color, and numeric character color of these characters are automatically changed depending on the time zone. FIG.
In steps A, B, C, D, E, F, and G, the current time of the clock means provided in the control circuit 19 is determined, and according to the determined time zone, the steps H,
The character color and the back color numeral character color are changed with I, J, K, L, M, N, O. Table 1 shows the colors in each time zone of the present embodiment.

[0013]

[Table 1]

FIGS. 6A and 6B show display examples of the liquid crystal display device in the clock mode. FIG. 6A is a display example of the time zone (20:00 to 4:59). In this case, in step H, the data (1) is set in the RAM, and the color of the character (star, moon, etc.) is yellow, The back color is black and the numeric characters are white. FIG. 6B shows a display example of the time zone (6:00 to 6:59). In this case, data (3) is set in the RAM in step J,
The color of the character (sun, flower, etc.) is yellow, the background color is red, and the number character color is white. As described above, in the present embodiment, the character displayed on the liquid crystal display device 9 in the clock mode is changed according to the time zone, and the character color, the back color, and the numeric character color are automatically changed according to the time zone. Therefore, the user can grasp the current time zone by the displayed characters and colors. The current time can be accurately grasped by displaying the current time digitally displayed.
