[Field of Invention]

The present invention relates to a wireless telephone that can maximize the convenience of use by configuring the handset-type wireless telephone to separate the receiver and the main body like a current wired telephone by a coil cord, so that the wired telephone can be used as a wireless telephone. Although the device was designed by the present inventors (Utility Model Publication No. 94-1178), it was provided in the form of an adapter attached to a landline telephone, there were many restrictions on the implementation.

This can be improved and implemented in the landline phone itself to achieve the desired purpose as well as to provide more convenient. Providing a handset-type cordless phone in the form of a landline phone with a coil cord is placed in the reception set of the office and home. The present invention has been made in that the inconvenience to solve the inconvenience, the dial keyboard can be enlarged to make it easier for older people to use and design a variety of products.

[Background of invention]

With the development of technology, wireless telephones, which are widely used, provide convenience to life. Currently, products that can be used by connecting multiple handsets to one main body have been developed to maximize convenience for the whole family. However, since the radiotelephone integrates all functions into the handset and is gradually miniaturized and lightened, it is inadequate to be placed on the reception set of an office or home.

In addition, with the miniaturization of the phone, the dial button size is small and it is not easy for elderly people to use the dial, so the dial keypad should be larger like the current landline phone, but this is not possible due to the limitation of the handset, and also because the weight of the handset is small There is a problem that the battery is easily discharged by using a battery, and to solve this problem, a high capacity battery must be provided, which is limited in size and weight to be applied to the current handset type, and ultimately, the handset is separated by a coil cord like a landline telephone. Must be provided.

There are various forms of a method for providing a cordless telephone in the form of a wired telephone filed by the present inventor (utility model application 91-3315) and published (utility model notification 94-1178). First, cut the connection line between the telephone trunk line and the main body of the telephone and attach the transceiver. Second, cut the connection line between the telephone main body and the handset and attach the transceiver. Third, cut the connection line between the telephone main line and the telephone main body and the handset. There is a method of attaching a transceiver to the subdivision. Applicant No. 91-3315 for the wireless transmission and reception of the wireline telephone apparatus of the present inventors uses the first method, and an adapter including a bell signal detector, a directional separator, a wireless transceiver, and a call circuit detector is fixed to a wall. An adapter including a bell signal generator, a directional separator, a wireless transceiver, and a hook switch detector is attached to the telephone body to make it wireless. However, the circuit is complicated and the size of the adapter device is unreasonable.

The second method is the method of the present inventors published in the application 94-1178, which is used in ordinary cordless telephones. The main body of the cordless telephone has a function of minimizing functions such as a transmission / reception circuit, a relay, a password setting and a search function, and dialing, It is characterized by setting the on / off switch.

[Purpose of invention]

The object of the present invention is that, despite the convenient advantages of using a conventional handset type wireless telephone, it is difficult to install by position and wiring due to the power supply line and telephone line when the main body of the telephone is placed on the reception set, and the handset is placed on the reception set. There is a problem in that it is not suitable for stability and functionality.

In addition, although there are many cases of receiving a call while working, a speakerphone is used in this case. However, the present invention does not provide such a speakerphone function. However, the present invention provides a more convenient phone culture by providing such a function. Purpose.

As the society ages, the aging population is increasing. Most of the aging populations are looking for handset-type wireless telephones because they do not remember where they have been placed due to memory loss and decreased vision. To solve this problem, in order to solve this problem, the portability of the wireless telephone is somewhat sacrificed by designing it as a wired telephone as in the present invention, but the above-mentioned problem is solved by specifying a large number of reserved positions, and the dial size is determined to have good visibility. It is possible to apply a high capacity battery can be configured to enable even without frequent charging.

[Summary of invention]

The present invention relates to a wireless telephone having a main body and a handset connected to a coil cord like a wired telephone. The telephone line includes a main body comprising a wireless transmission / reception circuit, a telephone controller, and a ringtone processing circuit, and corresponding counterpart wireless. The wireless handset receiver circuit, the control circuit, the handset sensing circuit, the speakerphone circuit, the battery, the coil cord and the speaker, and the microphone are configured to provide the telephone in the form of a cord separated from the receiver and the main body like a current wireline telephone. The mobile phone is used to move and use the speakerphone when receiving a call while working. The detailed description will be given below with reference to the accompanying drawings.

Detailed description of the invention

It is a cordless phone provided in the form of a main body and a receiver separated by a line like the wired telephone of the present invention.
