Abstract

PURPOSE:To provide the telephone set whose dial button part is not dirty and which is used by the same operation as that of a conventional telephone set and to provide the handset used for a conventional telephone set and for a numeral entry device. CONSTITUTION:A open/close cover 5 is provided on a dial button part 4, and when the cover 5 is open, it is discriminated to be ON-hook, then a line is acquired and when a call tone is detected, the cover 5 is automatically closed. Furthermore, when a numeral input cover is mounted onto the dial button part 5, the handset is devised that a code generated at depression of a button is automatically converted from a telephone code into a numeral entry code.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to make a telephone network call to a telephone which is making a call through a public telephone line.
The present invention relates to a handset with dial buttons for transmitting and receiving.

[0002]

2. Description of the Related Art A conventional telephone is composed of a transmitter / receiver unit, a dial operation unit for designating the other party, a line control unit, and the like. In most cases, the dial is exposed.

Further, the conventional handset with dial buttons has a dial button for instructing a connection destination telephone number when making a call from the telephone network, and the arrangement of the dial buttons is generally a general arrangement of telephones.

[0004]

In the above-mentioned telephone, since the dial portion is exposed, there is a problem that it is easily covered with dust and is easily soiled. Is.

[0005] In addition, in a type of telephone having a dial button on the handset, there is an inconvenience that the handset touches and pushes the dial button.

It is also convenient if the dial buttons of a handset can be used as a numeric keypad by connecting them to a compound terminal or the like, but the dial button arrangement of a general telephone is the same as the numeric button arrangement of a numeric keypad generally used for numerical input. I am not familiar with entering numbers. In particular, the numeric keypad layout is indispensable for an expert who inputs at high speed, such as a computer operator, but the conventional handset does not have the function of satisfying such a practical need.

It is an object of the present invention to provide an improved telephone and handset with the necessary practical features that are lacking in the prior art telephones described above.

[0008]

The telephone according to the present invention comprises:
An openable / closable cover provided on the dial button portion, a means for detecting that the cover is opened, a means for automatically opening / closing the cover, an off-hook detection function, a ringing tone detection function, and an on-hook state Means for operating the on-hook dial function when it is detected that the cover has been opened, and means for automatically opening the cover unless a call is received when off-hook is detected when the cover is not opened. And a means for automatically closing the cover when a ringing tone is detected while the cover is open.

The handset according to the present invention has a button key cover detachably attached to a handset with dial buttons, a means for detecting the presence or absence of the button key cover, and a button press depending on the presence or absence of the button key cover. And a code generating means for changing a generated code at time.

[0010]

In the telephone of the present invention, the on-hook dialing function operates when it is detected that the cover is opened in the on-hook state, and when the off-hook is detected when the cover is not opened, the cover is not called. The cover is configured to open automatically when the ring tone is detected when the cover is open, so the dial section is not exposed except when necessary, and it is difficult for dust to collect. Therefore, according to the present invention, a clean telephone can be realized.

Further, the off-hook operation automatically opens the dial cover so that the subsequent operation can be smoothly expanded.

Further, since the operation of opening the dial cover directly designates the on-hook dial, the subsequent operation can be smoothly developed.

Further, since the dial cover is automatically closed by detecting the ringing tone, the operation is easy, and in the case where the handset is equipped with a dial portion, the finger touches the finger when holding the handset for a call. There is no need to accidentally press a dial button.

Further, since the handset according to the present invention is constructed so that the code generated when the button is pressed changes depending on whether or not the button key cover is set, it is versatile and has the most convenient form for each purpose. Can be used.

A handset with dial buttons is provided with a numeric keypad button key cover, means for detecting the presence or absence of the button key cover is set, and the code generated when the button is pressed is changed according to the presence or absence of the button key cover set. As a result, it is possible to realize an input device that is easy to use even for a person who can operate the numeric keypad, and can be effectively used as a means for inputting numerical values when connecting a handset to a composite terminal device or the like.

[Other Embodiments] In the above embodiment, the button key cover has a ten-key arrangement, but another arrangement, for example, a button key cover showing function keys, is used, and the generated code is not a numerical value. It can also be used as a special code.

In the embodiment, the button key cover is one type, but if the cover attachment detection circuit is devised so that the type of the button key cover attached can be discriminated, a plurality of button key covers can be supported. , More codes can be generated and the range of use can be expanded.

[0109]

As described above, the telephone of the present invention operates the on-hook dial function when it is detected that the cover is opened in the on-hook state, and detects the off-hook when the cover is not opened. When the cover is open, the cover is automatically opened when the call is not made, and when the ring tone is detected when the cover is opened, the cover is automatically closed. Since the parts are not exposed and dust is not easily accumulated, the present invention can realize a clean telephone.

Further, since the dial cover is automatically opened by off hooking, the subsequent operation can be smoothly developed.

Further, since the operation of opening the dial cover directly designates the on-hook dial, the subsequent operation can be smoothly developed.

Further, since the dial cover is automatically closed by detecting the ringing tone, the operation is easy, and in the case where the handset is equipped with a dial part, the finger is touched when holding the handset for a call. There is no need to accidentally press a dial button.

Further, since the handset according to the present invention is constructed so that the code generated when the button is pressed changes depending on whether or not the button key cover is set, it can be used for various purposes and in the most convenient form according to each purpose. can do.
