Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a small portable cassette tape recorder.

Conventional configuration and its problems Hitherto, portable type cassette tape recorders have been known in which the first state in which no cassette tape magazine is installed is smaller than the second state in which the cassette magazine is installed. However, since the operation switch that determines the mode of the tape recorder is always located in an operable part, there is a problem in that it can be operated even in the first state when no cassette tape magazine is installed. In other words, if an attempt is made to add a radio receiver as another functional device to a cassette tape recorder whose first state is smaller than the second state, the switch operation as a tape recorder is possible even in the first state. However, there was a problem in that it was not possible to distinguish between radio reception functions as a multifunctional device based on the above-mentioned state changes.

Purpose of the Invention The present invention solves the above-mentioned conventional drawbacks, and is capable of combining other functional devices by adding other functional devices, and also changing the state in which the operable state of the combined functional device can be distinguished. It is an object of the present invention to provide a cassette tape recorder that can be used based on

Structure of the Invention In order to achieve the above object, the cassette tape recorder of the present invention has a switch for driving each mode in a first state in which a cassette tape magazine is not installed and in a second state in which a cassette tape magazine is installed. This feature is characterized in that it is configured to disable the operations of According to such a configuration, it is possible to operate only other functional equipment, such as a radio receiver, in the first state, and the other functional equipment can be combined and changed depending on the state change. This method has the advantage of being able to distinguish between operable states of complex functional devices.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described based on the drawings. Figures 1 and 2 show an embodiment of the cassette tape recorder of the present invention. Figure 1 shows the state in which no cassette tape magazine is installed, and Figure 2 shows the second state in which the cassette tape magazine is installed. The first state has a smaller overall shape than the second state. 1 and 2, reference numeral 21 denotes a cassette tape recorder body, which is constructed so that the cassette lid 14 is slidable and rotatable to a second pulled out state. The cassette tape recorder main body 21 is equipped with respective switches for realizing the basic mode as a tape recorder, and among these switches, there is a PLAY button 1 which operates the switch to set the PLAY mode, and a switch which sets the switch to the STOP mode. On the other hand, the cassette lid 14 is provided with an FF button 3 for operating the FF switch for fast forward mode, and a REW button 4 for operating the REW switch for rewind mode. ing. Also,
The cassette tape recorder body 21 also includes a volume 5, a radio tape selector switch 6,
Noise reduction switch 7, tape position switch 8, tuning knob 9, band (FM-AM) switch 10, band pointer 1
1, a headphone jack 12, and an external DC power supply jack 13 are provided. Further, the cassette tape recorder main body 21 is provided with a take-up reel 3' and a supply reel 4', and the take-up reel 3' is equipped with an FF switch (not shown) for setting a fast forward mode. The supply reel 4' is also provided with a REW switch (not shown) for setting the rewind mode.

In such a configuration, in playback mode
PLAY button 1 and STOP button 2, which sets the stop mode, are pressed when the cassette lid 14 is in the first state.
It is covered and cannot be operated. Similarly, the FF button 3 and the FF button 3 provided on the cassette lid 14
As shown in FIG. 3, the REW button 4 is not engaged with the take-up reel 3' and the supply reel 4', and similarly cannot be operated.
Therefore, in this first state, the PLAY switch, STOP switch, which realizes the basic mode of the tape recorder on the tape recorder main body 21 side,
Since the FF switch and REW switch cannot be operated, it can be determined that the tape recorder is not functioning. In this first state, each switch and knob for the radio receiver can be operated.

On the other hand, when the cassette tape magazine 15 is installed in the second state, the cassette lid 14 slides in the direction of the arrow in the figure for the first time, as shown in FIG. It is exposed and becomes operable. At the same time, as shown in FIG. 4, the take-up reel 3' and the FF button 3, and the supply reel 4' and the REW button 4 are superimposed, respectively.
These operations become possible, and the mode operation of the cassette tape magazine 15 becomes possible.
This second state can therefore be distinguished as being the functional state of the tape recorder.

On the other hand, since this embodiment has a built-in FM-AM radio receiver, radio reception is possible in the small first state as shown in FIG. 1, and its portability is excellent.

Effects of the Invention As described above, according to the present invention, a multifunction device is provided with an operation mode for a tape playback function that allows a cassette tape magazine to be attached and played back, and an operation mode for a radio reception function that allows radio reception. The tape recorder is provided with a cassette lid configured to be movable such that a first state in which a cassette tape magazine is not installed is smaller than a second state in which a cassette tape magazine is installed, and the cassette lid is A tape operation mode operation button is provided on the cassette lid, and at least the tape operation mode operation button on the cassette lid is configured so that the tape operation can be operated only in the second state; Depending on the mode operation button, the radio reception operation can be operated in both the first and second states.
Based on the second state change, it is possible to clearly distinguish between the tape recorder's original functional mode and the operable state of the combined radio reception mode, and in the first state in which no tape cassette is attached. The overall size is smaller and the radio reception function can be fully demonstrated.
