Abstract

PURPOSE:To operate a compound functional device only in the first state where a cassette tape magazine is not set, by constituting the device so that switch operations for mode driving in the second state, where the cassette tape magazine is set, are made ineffective in the first state. CONSTITUTION:A play button 1 and a stop button 2 which sets the stop mode are covered with a cassette cover body 14 and cannot be operated in the first state where the cassette tape magazine is not set. Similarly, an FF button 3 and an REW button 4 provided on the cassette cover 14 are not engaged with a take-up reel 3' and a supply reel 4' respectively and cannot be operated. Consequently, this device is judged to not be in the state of tape recorder functions because the play switch, the stop switch, the FF switch, and the REW switch which realize fundamental modes of a tape recorder in the side of a tape recorder body 21 cannot be operated in this first state. In this first state, switches and knobs for functions of a radio receiver can be operated.

Description

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

Conventional Structure and Problems There has been known a portable type cassette tape recorder in which the first state in which a cassette tape magazine is not installed is smaller than the second state in which a sumo wrestler 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.

That is, when trying to add a radio receiver as another functional device to a cassette tape recorder that is smaller in the first state than in the second state, the switch operation as a tape recorder is possible even in the first state. Therefore, there was a problem in that it was not possible to distinguish between radio receivers as complex functional devices even when the above-mentioned state changed.

Purpose of the Invention The present invention solves the above-mentioned conventional drawbacks, and it is possible to add other functional devices to combine them, and to distinguish between the combined functional devices based on state changes. The purpose of the present invention is to provide a cassette tape recorder that can perform the following operations.

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 this 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 eliminates the advantage of being able to distinguish between complex functional devices.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described based on the drawings. 1st
1 and 2 show an embodiment of the cassette tape recorder of the present invention, FIG. 1 shows a state in which no cassette tape magazine is installed, and FIG. 2 shows a second state in which a 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 configured such 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 switches for realizing the basic mode as a tape recorder, and among these switches, PLA
1. PLAY button to operate the switch for Y mode.
A 5TOP button 2 is provided to operate a switch to set the 5TOP mode, while an FF button 3 is provided on the power center lid 14 to operate the FF switch to set the fast forward mode, and a REW switch to set the rewind mode. R to do
An EW button 4 is provided. In addition, the above-mentioned tape recorder body 21 has a volume 5, a radio tape selector switch 6, a noise reduction switch 7, a tape position switch 8, a tuning knob 9, a band (FM-AM) switch 10, A band pointer 11, a Henodo phone jack 12, and an external DC power jack 13 are provided. Further, the cassette tape recorder body 21 is provided with a take-up reel 3' and a supply reel 4'.
' is an FF switch (not shown) for fast forward mode.
is equipped. The sub-reel 4' is also provided with a REW switch (not shown) for setting the rewind mode.

In such a configuration, the PLAY button 1 for playback mode and the 5TOP button 2 for stop mode are covered by the cassette lid 14 in the first state and cannot be operated. Similarly, the FF button 3 and REW button 4 provided on the cassette lid 14 are not engaged with the take-up reel 3' and supply reel 4', respectively, as shown in FIG. 3, and cannot be operated in the same manner. do not have.

Therefore, in this first state, P that realizes the basic mode of the tape recorder on the tape recorder main body 21 side is
LAY switch, 5TOP switch, FF switch,
Since the REW switch cannot be operated, it can be determined that the tape recorder is not functioning. In this first state, each switch and knob of the radio receiver can be operated.

On the other hand, when the cassette tape magazine 16 is in the second state where it is loaded, the cassette lid 14 slides in the direction of the arrow in the figure for the first time as shown in FIG. will be exposed and ready for operation. At the same time, as shown in FIG. 4, the take-up reel 3', the FF button 3, the supply reel 4' and the REW button 4 are in a superimposed state, and these operations are possible. Mode operation of the tape magazine 15 becomes possible. This second state can therefore be distinguished as a 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 even in the first state where the shape is small as shown in Fig. 1, and its portability is excellent. .

Effects of the Invention As described above, according to the present invention, in the first state where the cassette tape magazine is not installed,
Since the configuration is such that the switch operations for each mode drive are disabled in the second state where a cassette tape magazine is installed, the combined functional equipment can be operated only in this first state. First, when compounding This has the advantage that the operable state of the complex functional device can be clearly distinguished even when the second state changes.
