At this time, the pointer 4 provided on the cassette lid 2 is interlocked with the tuning knob 8, and by tuning to the frequency printed on the front panel 3, it is possible to tune to the frequency of the broadcasting station. Further, the volume can be varied with a volume adjustment knob 10.

Problems to be Solved by the Invention However, in the above configuration, various knobs for the radio receiver are arranged on the upper surface perpendicular to the main surface of the cabinet on which the cassette lid body 2 is provided. It is difficult to operate, and there are limitations in the arrangement of each knob, etc., and there are problems in terms of miniaturization and operability of the set.

In view of the above-mentioned problems, the present invention aims to improve the operability during radio reception.

Means for Solving the Problems In order to solve the above problems, the cassette tape recorder with radio receiver of the present invention has a main body cabinet that incorporates a tape drive mechanism as a cassette tape recorder and an electric circuit as a radio receiver. and the misuse of the preset button for storing the number of holders for holding cassette tapes, which is attached to the main body cabinet so that it can be opened and closed, and the liquid crystal display section and electronic tuning operation section that display the frequency selected by these buttons in conjunction with each other. It is characterized by the provision of a prevention switch.

According to the above-described configuration, the present invention can utilize space more effectively by providing an operating section as a radio receiver on the surface of the cassette lid, and can also be operated more easily by using a preset method. Become.

Embodiment Hereinafter, a cassette tape recorder with a radio receiver according to an embodiment of the present invention will be described with reference to the drawings.

1 to 3 show a cassette tape recorder with a radio receiver according to a first embodiment of the present invention.

In FIGS. 1 to 3, 11 is a main body cabinet, and a tape drive mechanism 34 as a cassette tape recorder is connected to a lid cabinet 33 to be combined.
and a printed circuit board 3 for electrical circuits as a radio receiver
1 is built-in. 12 is a cassette lid rotatably attached to the main cabinet 11, and 13 is a panel of the cassette lid 12, which is made of a transparent plastic plate. 14 is an electronic tuning button, 15 is a preset button,
16 is a memory button for presetting, 17 is a tuning stop button for tuning, 18 is a liquid crystal display, 19 is an operation knob for the tape drive mechanism 34, 2o is a radio/tape selector switch knob, and 21 is a cassette lid 12 switch knob. It is a fulcrum hole for rotation.

The cassette lid body 12 has a holder 28 for holding the cassette tape, and a button guide 22. Rubber switch 23 and printed circuit board 24t
