As shown, the telephone of the present invention is a hand-free type in which the plug 30 and the dialing device 40 and the hooking switch 51, the handset 52, and the handset 53 connected to the outlet 10 are integrally formed. The handset device 50 is divided into two parts.

3 is a schematic block diagram of a telephone according to the present invention. As shown in the plug 30, the user-free devices of the above-described telephone, namely the tip and ring terminals T and R, the rectifier circuit 31, the control device 32, the ring sound generating device 33 and The call circuit 34 is comprised. The control device 32 in the plug 30 is connected to the dialing device 40 and the call circuit 34 is connected to the handset device 50. In other words, the user-use device is composed of a dialing device 40 and a handset device 50, respectively, and these devices are connected to a plug 30 in which the user-free device is configured.

In the above-described configuration, the rectifier circuit 31 configured in the plug 30 rectifies the voltage of the telephone station provided through the tip terminal T and the ring terminal R, and supplies the rectified voltage to the control device 32. Here, when no telephone call is established, the rectifier circuit 31 is not necessary because a DC voltage of -48 V is provided between the tip terminal T and the ring terminal R, but a ring signal is provided from the telephone station, In the case where the voice signal is input, since a DC voltage including an AC component is provided, the rectifier circuit 31 should be used, and it will be easily understood by those skilled in the art.

The control device 32 operates by the voltage supplied from the rectifier circuit 31, and monitors the operation of the hooking switch 51 in the handset device 50 as described later, and sends a hooking signal to the communication circuit 34. to provide. In addition, the control device 32 has an analog / digital change unit and DTMF generating means therein, detects the voltage from the dialing device 40 as a digital signal, and converts the DTMF signal corresponding to the detected digital signal into a communication circuit. Provide to 34. That is, the dialing device 40 is composed of a plurality of voltage distribution resistors R1-R13 and switches SW1-SW12 as shown in FIG. It provides to the control apparatus 32. Here, the switches SW1-SW12 correspond to 0 to 9 and the # and * keys of the telephone. Accordingly, the control device 32 detects which switch SW1-SW12, i.e., the numbers 0-9 or the * or # keys, corresponding to the voltage from the dialing device 40, and converts the corresponding DTMF signal into the call circuit. 34 to provide. It will be readily appreciated by those skilled in the art that the number of switches and resistors in the dialing device 40 can be increased as needed. In addition, in the case of configuring the above-described switches (SW1-SW12) as a membrane switch can be configured as a pad as shown in Figure 2 can be easily understood by those of ordinary skill in the art. will be.

The communication circuit 34 is connected to the tip terminal T and the ring terminal R, and toggles to the hooking on / off state as a hooking signal from the control device 32 is provided. That is, when the hooking signal is provided in the hooking-on state, the call circuit 34 switches to the hooking-off state through the tip line and the ring line, but switches to the hooking-on state when the hooking signal is provided in the hooking-off state. In the hooking-off state, the call circuit 34 is in a state capable of making a call with the telephone station as described above, providing the DTMF signal from the control device 32 to the telephone station, and sending the voice signal from the telephone station to the handset of the handset device 50. A voice signal from the talker 52 to a telephone station.

The ring sound generator 33 connected to the tip and ring terminals T and R of the plug 30 determines whether a ring signal is provided through the tip and ring terminals T and R, and when the ring signal is provided, It is comprised so that a predetermined ring sound may be output through the speaker 41 comprised in the dialing device 40. FIG. In this embodiment, the speaker 41 is shown and described as being configured in the dialing device 40, but the configuration position of the speaker 41 can be modified as necessary, it is easy for those of ordinary skill in the art. You will know.

The handset device 50 is composed of the handset 52, the handset 53, and the hooking switch 51 connected to the call circuit 34 of the plug 30 as described above, and the user has a hooking switch 51 ), The call circuit 34 can be driven in the hooking off / on mode as described above, and the call can be made using the handset 52 and the handset 53. Here, the handset device 50 may be configured as a hand free type in which the handset 52 and the handset 53 are integrally formed as shown in FIG. 2.

When a ring signal is provided from the telephone station in the circuit configured as described above, the ring tone generator 33 detects the ring signal and outputs a ring tone through the speaker 41 in the dialing device 40 to indicate that the user has come to the telephone. Notify. If the user wants to answer the call in response to a ring tone, the hooking switch 51 in the handset device 50 is activated, and the control device 32 in the plug 30 provides a hooking signal to the call circuit 34. do. The call circuit 34 switches to the hooking off state because the current state is the hooking on state (in the above description, the ring tone is provided from the telephone station, indicating that the call circuit 34 is operating in the hooking on mode). Therefore, the user can make a telephone call through the handset 52 and the handset 53 of the handset 50.

Contrary to the above situation, when a user makes a call, The user hooks off the call circuit 34 by operating the hooking switch 51 of the handset device 50 to form a call path with the telephone station. Then, the switch SW1-SW12 of the dialing device 40 is selected and operated to input the telephone number of the counterpart. The dialing device 40 sequentially provides a voltage corresponding to the input telephone number to the control device 32, and the control device 32 provides a DTMF signal corresponding to the input voltage to the call circuit 34. . At this time, since the call circuit 34 is in the hooking-off state, it provides the DTMF signal of the control device 32 to the telephone station, and the telephone station calls the counterpart corresponding to the telephone number input by the user. When the other party answers this call, a telephone line is established through the telephone station in the telephone period of the telephone and the other party of the present invention, so that a telephone call is possible.

As can be seen from the above description, it can be seen that the telephone of the present invention performs the same operation as a normal telephone. However, it is different from the conventional telephone in that it uses the divided voltage difference using the resistors R1-R13 to search for the operation switch among the switches SW1-SW12 of the dialing device 40. However, in the present invention, it can be seen that the configuration exposed to the outside by configuring the non-use devices not used by the user in the plug 30 is limited to the dialing device 40 and the handset device 50 only. That is, since the main components of the telephone are configured in the plug 30, the dialing device 40 and the handset device 50 that the user should use can be miniaturized. In addition, when the dialing device 50 is configured in a pad form using a membrane switch or the like as described above, the dialing device 40 is a mouse in which a computer mouse 70 is used as shown in FIG. It can be seen that the components that can be used as pads and are substantially exposed to the outside and occupy space are limited to the handset device 50. Since the handset device 50 is also composed of only the handset 52, the handset 53, and the hooking switch 51, the handset type can be configured in a very small size. When the handset type is configured, it can be seen that the required space is extremely small. .

As described above, when the dialing device 40 is used as a mouse pad, the following problem may occur.

When the dialing device 70 is used as a mouse pad in a state configured with a membrane switch or the like, the switches SW1-SW12 in the dialing device 40 are likely to be turned on as the mouse 70 moves. Therefore, when the user uses the mouse 70 on the dialing device 40 of the present invention during a phone call, that is, while the call circuit 34 is operating in the hooking-off mode, the switches SW1-SW12 in the dialing device 40 are used. Are turned on to provide the corresponding DTMF signal to the communication circuit 34. Therefore, the DTMF signal is transmitted to the other party as it is, so that the other party may be offended.

This problem can be solved by configuring the hold switch 42 in the dialing device 40 as shown in FIG. 5 and configuring the control device 32 to operate as follows. That is, the control device 32 provides the DTMF signal corresponding to the voltage provided by the dialing device 40 to the call circuit when the hold switch 42 is on, but dialing when the hold switch 42 is off. It is configured not to output the DTMF signal regardless of the provided voltage from the device 40. Therefore, when the dialing device 40 is to be used as a mouse pad during a phone call, the user turns off the hold switch 42 so that the corresponding DTMF signal is turned on even when the switches SW1-SW12 in the dialing device 40 are turned on. Can be prevented from being delivered to the other side.

On the other hand, when the dialing device 40 is configured as shown in FIG. 3, the configuration becomes complicated. That is, a plurality of variable resistors R1-R13 should be configured in the dialing device 40, and the control device 32 has a separate analog / digital conversion device for detecting a voltage from the dialing device 40, and the like. As a result, a problem arises in that the configuration is complicated and the manufacturing cost increases. This problem can be solved simply by configuring the dialing device 40 as shown in FIG.

As shown in FIG. 6, a processor 43 is configured in the dialing device 40, and a key matrix 44 is connected to the processor 43. The key matrix 44 is composed of a plurality of keys, i.e., keys corresponding to the dialing keys of the telephone, and the processor 43 can sense the pressed keys by providing and inputting a scan pulse to the key matrix 44. . The processor 43 transmits the pressed key information of the key matrix 44 to the control device 32, and it is common knowledge in the technical field of the present invention that the transmission method may employ any method enabling communication between processors. Those who have it will be easy to know.

In the case of configuring the dialing device 40 as shown in FIG. 6, since the key matrix 44 and the processor 43 can be downsized, the downsizing of the dialing device 40 is possible, in particular, the key information pressed from the processor 43. Is directly provided to the control device 32, unlike the case of FIG. 2, a separate analog / digital conversion device is not required in the control device 32.

In addition, if necessary, the hooking switch 51 and the hold switch 42 of FIG. 5 can also be configured as keys in the key matrix 44, which can be easily understood by those skilled in the art. will be.

As described above, in the present invention, by incorporating user's unused devices among the components of the phone into the plug of the phone, only the device in the user's phone can be exposed to the outside, thereby greatly reducing the use space of the phone. It works.
