Description

[Detailed explanation of the idea] The present invention relates to a car stereo.

Conventionally, in a car stereo with a tuner, as shown in Fig. 1, the front operation section has a cassette insertion slot a1 several preset buttons b1 a scale display C1 a balance adjustment knob d1
Volume and sound quality knobs e, dial knob f, etc. are provided.

To briefly describe a few examples of attaching the stereo unit to the car body, when attaching it to a dash board, etc., the mounting shafts of the knobs e and f are usually extended and the screws of the mounting shafts are used for mounting. Alternatively, the stereo unit was attached by screwing onto a mounting bracket fixed to the underside of the dash board.

However, as mentioned above, installing it below the dash board in the car reduces the space inside the car, and on the other hand, the stereo itself has internal mechanisms and performance that overlap with car radios etc. built into the in-dash. It is desirable to mount the car stereo by using the mounting space for the car radio provided on the dash board, for example, the opening.

Incidentally, although there are differences in standards for the installation space of car radios depending on the country, such as the distance between the axes of the knobs e and f, or the vertical and horizontal dimensions of the front operating body, it is generally It is now possible to store things.

However, when attaching the conventional stereo main body to a vehicle body, the front operation section cannot be made larger than a predetermined size.

Therefore, it is impossible to arrange the preset button b1 cassette insertion hole a1 on the front operation section or the knobs e and f on the stereo body equipped with the front operation section in a limited space, and moreover, it is impossible to arrange the preset button b1 on the front operation section, the knobs e, f, etc. on the stereo body equipped with the front operation section. , it was difficult to provide multipurpose functions.

The present invention was created in view of the above points, and its purpose is to separate the tuner, its operation dials, scale display, etc. from the stereo main body, which is the main body of the device, so that the cassette insertion slot of the main body of the device can be easily removed. The tuner can be attached and detached via the connector provided at the bottom, and remote control is possible by separating the tuner from the body of the device and placing it at hand. The purpose is to provide multi-functionality such as being shared with a radio, and to achieve effective use and high performance, such as making it possible to widely use the front operation section without changing the size of the main body of the device.

The details of one embodiment of the present invention will be explained below with reference to FIGS. 2 and 3. Reference numeral 1 has a built-in amplifier, a cassette recorder, etc., and when the front cassette insertion slot 2 is opened, the Arranged connector housing space 3
1 is a device body in which a female (male) connector 3 is installed, 4 is formed separately from the device body 1 and is separately formed, and has a knob 5 for switching power, individual broadcasting or FM broadcasting, etc. A tuner 9 is fitted in the connector housing space 31 and is supported. This is a male connector formed so as to be freely connectable to the female connector 3 so as to form a part of the outer shape thereof.

10. 11 is a balance adjustment knob and a volume/sound quality adjustment knob installed on the left and right sides of the front surface of the device main body 1; 12 is a dash board; 13 is an opening in the dash board 12, and is used to attach a conventional car radio. This is an opening for mounting.

Since one embodiment of the present invention has the above-described configuration, the device main body 1 is mounted by effectively utilizing the opening 13 of the dash board 12 of an automobile.

A cassette insertion slot 2, a knob 10 for adjusting the balance, and a knob 11 for adjusting the volume and sound quality are provided on the front side of the main body 1 of the device, which contains an amplifier and a cassette recorder.

Since the female connector 3 is installed in the device main body 1, the male connector 9 formed so as to form a part of the outer shape of the tuner 4 which is formed separately from the device main body 1 as described above is connected to the female connector 3. A housing space 31 in which a connector 9 formed to fit into and connect to the connector 3 and form a part of the outer shape of the tuner 4 is disposed below the cassette insertion port 2.
1 and the tuner 4 can be easily and securely connected as shown in FIG. It can be used in two ways when listening to cassette tapes.

In addition, when playing a cassette tape, it is sufficient to insert it into the cassette insertion slot 2 of the device main body 1, and if necessary, install a tuner 4 separate from the device main body 1 and connect the male connector 9 as described above. By connecting it to the female connector 3, the tuner 4 can be attached to the main body 1 of the device and the radio can be listened to.

Therefore, although conventionally it has been mechanically impossible to incorporate multifunctional mechanisms such as a car stereo and a car radio into the device body 1, it is now possible to achieve higher performance.

In addition, a tuner 4 is formed separately from the device main body 1.
By electrically connecting the tuner 4 with a cord or the like via a connector, it is possible to remotely control the tuner 4 and listen to the radio with only the tuner 4 at hand.

Moreover, only the male connector 9 to be formed on the tuner 4,
It is separated from the tuner 4 to form a male connector part (not shown), which can be attached to and detached from the tuner 4 (for example, a locking protrusion is provided on the male connector part, and an engagement recess that engages and disengages with the engagement protrusion is attached to the tuner 4). 4), and by fitting and connecting the male connector portion to the female connector 3 as described above, the tuner 4 can also be attached to the device main body 1.

As mentioned above, the present invention separates the tuner, its operation dials, scale displays, etc. from the stereo main body and forms them separately from the main body of the device, thereby making it possible to attach and detach the tuner to the main body of the device via the connector. By making the device flexible or by separating the operating device from the main body of the device and placing it at hand, remote control is possible, thereby providing multifunctionality such as the amplifier built into the main body of the device can be used as a car stereo and a car radio. At the same time, it is possible to achieve effective utilization and high performance, such as being able to widely use the front operation section without changing the size of the main body of the device.
