Abstract

PURPOSE:To use the title telephone set without taking into consideration the direction of a handset by switching and using two transducers for a transmission and a reception by means of the operation of a push button switch. CONSTITUTION:A push button switch 5 and an operating part 11 of the push button switch 5, which is composed so as to project from a hole provided at a receiver part 9, are possessed inside a handset 1. In a condition in which the operating part 11 is pushed inside the handset 1 by the contact with the ear of a user, for four interlocking change-over switches inside the push button switch 5, contact points a1c1 to a4c4 are respectively closed, the operating part 11 does not make contact with the head part of the user, in a condition in which the operating part 11 projects from the hole of the receiver part 9, contact points b1c1 to b4c4 of the change-over switches SW1 to SW4 are closed. Thus, in any case, the transducer on the mouth side of the user is always operated as a microphone.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a wireless telephone, and more particularly to a wireless telephone that wirelessly transmits and receives signals between a handset and a telephone body.

(Prior Art) Conventionally, this type of telephone has been composed of a telephone body connected to a telephone line and a handset. There is no connecting cable between the two, and signals are sent and received wirelessly. The operation is as follows.

FIG. 5 shows an example of the configuration of a conventional wireless telephone. The packing machine main body 6 has a radio transmitter/receiver 7 for the telephone main body, and is connected to a telephone line 8.

On the other hand, a transducer 2 for receiving calls is installed in the receiver section 9 of the handset 1, and a transducer 3 for sending calls is installed in the transmitter section 10. Inside the handset 1, a wireless transmitter/receiver 4 is installed to transmit and receive signals wirelessly with a wireless transmitter/receiver 7 for the telephone body inside the telephone body 6. Vessel 1
A connecting cable between the telephone main body 6 and the telephone main body 6 can be omitted.

(Problem to be Solved by the Invention) By the way, in a general telephone in which the handset and the telephone main body are connected by a connecting cable, the user has to attach the connecting cable to the handset depending on the position of the handset and the transmitter. However, with the wireless telephone mentioned above, there is no connection cable that connects the handset and the telephone body, so the user cannot easily distinguish between the handset and the transmitter. In order to do this, in the past, improvements were made to the shape design of the handset. Therefore, there was a drawback that there were restrictions on the shape design of the handset.

In addition, in the conventional radio telephone described above, the transducer 2 in the handset section 9 is fixedly used for receiving calls, and the transducer 3 in the transmitter section 10 is used fixedly for sending calls. Even if the transducer is usable with an electrical circuit, it is impossible to use the handset 1 in the reverse direction, in which the transducer 2 is used for transmitting and the transducer 3 is used for receiving. For this reason, if the user accidentally uses the handset 1 in the opposite direction, there is also the drawback that a call cannot be made at all.

(Means for Solving the Problems) A wireless telephone according to the present invention includes a handset and a telephone body that transmit and receive signals wirelessly to each other. The transducer includes two transducers capable of operating in a use mode, and a push button switch provided protruding from the handset and controlling the operation of the two transducers in the use mode.

(Example) Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.

In FIG. 1, the same members as in FIG. 5 are given the same reference numerals, and their explanations will be omitted.The characteristic feature of the six-piece repair example is that there is a push button switch 5 inside the handset l and a push button switch 5 provided in the handset part 9. The actuating part 11 of the push button switch 5 is configured to protrude from the hole. Here, the same transducer 2 and 3 are used.

FIG. 2 is a principle diagram illustrating the operation of the push button switch 5 in the embodiment of FIG. 1. In Figure 2 -R
IR2 is a wireless transmitter/receiver for handsets (hereinafter referred to as transmitter/receiver 1114
The receiver signal terminal TIT2 of the transmitter/receiver 4 is also the transmitter terminal of the transmitter/receiver 4. push button switch 5
is composed of four interlocking changeover switches SWI to SW4.

In the embodiment of FIG. 1, the operating part 11 protruding from the hole in the handset part 9 is pushed into the interior of the handset l by contact with the user's ear.

In this state, all four interlocking changeover switches inside the push button switch 5 have contacts alcl, a2c2, . . . as shown in FIG. a3c3゜a4c4. are configured so that they are each closed. Therefore, the handset terminal RIR2 is connected to the transducer 2, and the transmitter terminal T
IT2 is connected to transducer 3. As a result, in the embodiment of FIG. 1, transducer 2 operates as a receiver, and transducer 3 operates as a transmitter.

Next, referring to FIG. 3, the operation when the user uses the handset 1 in the reverse direction in the embodiment shown in FIG. 1 will be described.

In FIG. 3, the usage state of the handset 1 is the up-down white path. That is, the receiver section 9 corresponds to the user's mouth side, and the transmitter section 10 corresponds to the user's ear side. The principle of operation in this state of use will be explained with reference to FIG.

In the usage state shown in FIG. 3, the operating portion 11 of the push button switch 5 protrudes from the hole in the receiver portion 9 without coming into contact with the user's head. In this state, the four interlocking changeover switches SW1 inside the pushbutton switch 5
~SW4 are all connected to contacts blcl and b2 as shown in Fig. 4.
c2. b3c3 and b4c4 are configured to be closed.

Therefore, the receiver terminal RIR2 is connected to the transducer 3, and the transmitter terminal TIT2 is connected to the transducer 2. As a result, in the usage state shown in FIG.
will operate as a receiver.

1 and 3, the operation of the push-button switch 5 causes the transformer on the user's mouth side to be activated in both cases, even though the usage state of the handset 1 is reversed vertically. The duuser always operates as a transmitter.

(Effects of the Invention) As explained above, the radio telephone according to the present invention includes two transducers for transmitting and receiving, and a push button switch whose operating portion protrudes from the handset. By making it possible to switch between the two transducers for sending and receiving calls by operation, the directionality of the handset is eliminated, and the transducer on the side of the user's ear is always used as the receiver. It becomes possible to always operate the side transducer as a transmitter. As a result, it is possible to make a call regardless of the direction in which the handset is used, and the user has the advantage of being able to use the handset without considering the orientation of the handset. Furthermore, since there is no need to distinguish between a transmitter and a receiver, there is also the advantage that there are no restrictions on shape design.
