Abstract

The utility model relates to a telephone set with a handle having a roller, which belongs to the field of communication. The utility model is a telephone set which is provided with a roller in a handle, rapidly makes a phone call and realizes a mute function during taking. The utility model has the technical scheme that the I /O port of the processor of the telephone set is connected with the external pin of the roller of the handle, the roller can rotate forwards and backwards and can be pressed down, a roller circuit feeds the state information of the roller back to the processor of the telephone set by testing the certain state of the roller, and then the processor correspondingly renovates the information of telephone numbers on a liquid crystal screen or directly makes a phone call according to the received information. The utility model has the advantages that the operating procedure of a user making a phone call and searching the telephone numbers is simplified, and as long as the roller on the handle is rotated by a single hand, the operation can be completed; the utility model can reduce the time for searching and confirming the telephone numbers, and meanwhile, the telephone set can realize the mute function by only operating the roller in the talking process.

Description

The telephone set of handle band roller

Technical field

The utility model belongs to communication field, is a kind of telephone set with fast dialing telephone and call office realization mute function of handle band roller.

Background technology

At present, the telephone set that has occurred the various PDA of having (personal digital assistant) function on the market, one of their characteristics are that the software section of telephone set has designed and can allow the telephone directory of user storage some telephone numbers, can call by certain user interface simultaneously.Though this type of telephone set can be stored a large amount of telephone number informations, the user operates, and still needs more loaded down with trivial details searching and the affirmation process.

Summary of the invention

The purpose of this utility model is: the user is searched efficiently and easily and call and design the telephone set that a kind of handle has roller, after the user is picking up handle, search rapidly and call, and can realize the call office mute function by forward and reverse swing roller.

Technical essential of the present utility model is: a roller is set in Telephone handset, and this roller can be rotated in the forward, reverse rotation and can being pressed, and roller is connected with the telephone set processor by the Telephone handset line.When the user picked up handle, the LCDs of telephone set showed the telephone number information in the telephone directory at once, and the user can select telephone number corresponding information by forward and reverse swing roller.When roller rotates, the rotation status that the roller circuit of telephone set can detect roller automatically promptly is rotated in the forward or reverse rotation, the telephone set processor judges that according to the roller circuit user selects the direction of telephone number information, and the telephone set LCDs correspondingly makes progress or downward roll display; When the roller electric circuit inspection is pressed during to a certain position of roller, telephone set will be dialed selecteed telephone number on the display screen automatically; In the user's communication process, if the user is once more by bottom roller and keep the roller state that is pressed, telephone set enters mute state so, and promptly we can hear that the other side speaks, but the other side can't hear we and speak, and telephone set recovers normal talking behind the relieving roller.

The effect of roller circuit is the state that detects being rotated in the forward of roller, reverse rotation and be pressed, and detected state information is fed back to the telephone set processor; 3 internal switches are arranged in the roller circuit, and the sequencing by 2 switch closures wherein and the closure state of other 1 switch detect the state of roller.

The external pin of handle roller links to each other by two lines with the I/O mouth of telephone set processor, the telephone set processor alternately is changed to high level with I/O, conducting by judging coupled unidirectional conducting diode and closure state are judged the closure state of the internal switch in the roller circuit, and state information is sent to the telephone set processor, processor is according to the information of the receiving telephone number information on the update displayed LCD screen or directly call correspondingly.

The beneficial effects of the utility model are, the simplification user calls the operation sequence with enquiring telephone number, only need the roller on the singlehanded rotary handle to get final product complete operation, significantly reduced the time of searching and confirming phone, in communication process, only need operated roller just can realize the mute function of phone simultaneously.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structure principle chart of the present utility model.

Fig. 2 is the roller action logic figure of roller circuit of the present utility model.

Fig. 3 is appearance figure of the present utility model.

1-roller 2-LCDs 3-telephone base

Embodiment

In the structure principle chart of Fig. 1, the I/O mouth of telephone set processor links to each other by line with the external pin of roller circuit, and its concrete circuit connecting relation is: link to each other with the I/O2 interface of telephone set processor after the end parallel connection of pin Com, SW1; The other end of Com links to each other with the end of K switch 1, K2 respectively; The other end of K1, K2 with after pin A, B link to each other, links to each other with the positive pole of diode D1, the negative pole of D2 respectively again; The other end of SW1 links to each other with an end of K switch 3; The other end of K3 links to each other with the I/O1 interface of processor with the negative pole of D1, the back anodal in parallel of D2 with after pin SW2 links to each other again.

In the roller action logic figure of the roller circuit of Fig. 2, low level represents that switch is an off-state, and high level represents that switch is a closure state; When roller did not rotate, K switch 1, K2 all were in off-state; When roller was pressed, K switch 3 was in closure state; When roller was rotated in the forward, the closed sequencing of K switch 1, K2 was: K1 is at first closed, K2 closure then, and K1 disconnects; Last K2 disconnects, and promptly K1 closure and disconnection are all early than K2; When the roller reverse rotation, the closed sequencing of K switch 1, K2 is: K2 is at first closed, K1 closure then, and K2 disconnects again, and last K1 disconnects, and promptly K1 is closed all is later than K2 with disconnecting.

Fig. 3 is an outside drawing of the present utility model, the handle right side of telephone set is provided with a roller (1), telephone base (3) is gone up except that having 9 numerical keys, 1 " * " number key and 1 " # " number key, also is provided with 6 function shortcuts, 4 indicator lights and 1 LCDs (2); 6 function shortcuts are respectively: dodge disconnected, hands-free, redial, switching, quiet and fast group; 4 indicator lights are distinguished display power supply, phone, hands-free and information.

When user's off-hook, the LCDs of telephone set (2) shows the telephone number information in the telephone directory at once, can select the telephone number of needs this moment by the roller on the rotary handle (1), LCDs (2) is according to the rotating direction of roller (1) and the roll display telephone number information, for example select by " Hanwang Technology's exchange 82675168 ", cursor on the LCDs (2) rests on this telephone number information place, promptly dialed " Hanwang Technology's exchange 82675168 " at once by bottom roller (1) this moment again, after putting through, phone can begin to converse with the other side, when environment is noisy in the our communication process, can press bottom roller (1) once more, realized the mute function of phone, originally can hear that promptly the other side speaks, the other side can't hear we and speaks, and telephone set recovers normal talking behind the relieving roller.

The utility model only just can be searched and call the user fast with singlehanded, and can realize mute function easily, and is simple to operate, convenient easy-to-use.
