Description

A kind of number input unit fast and safely

The utility model relates to a kind of number input unit that is mainly used in telephone communication.

At present increasing people is using phonecard, and as 300 cards, IP phonecard etc., the use of these cards has brought convenience also to save telephone expenses to toll message.But need import a lot of information desk number and card number etc. during owing to these cards of use, not only time-consuming but also make mistakes easily when therefore using, particularly more sense inconvenience concerning the relatively poor people of those memory, often need during use while seeing that the number on the phonecard Enters Number, when using in public, then causing card number, password to be spied on by other people easily steals or causes the number of dialling to be deposited in redialing in the memory of telephone set, thereby cause phonecard by people's free call on sb. else's expense through illegal means, report is arranged during the example of this respect.

The purpose of this utility model is to provide a kind of can import number and long term storage the number input unit fast and safely that can once send when needing in advance.

This device is provided with box body, dialing keyboard, dial-up circuit, audio amplifier circuit, microphone device, DC power supply, printed circuit board (PCB) and switch.Box body is provided with vocal hole, dialing keyboard and switch are located on the box body, and dial-up circuit and audio amplifier circuit are welded on the printed circuit board (PCB), the output termination dial-up circuit of dialing keyboard, the output termination audio amplifier circuit of dial-up circuit, the output sending and receiving acoustic device of audio amplifier circuit.

Said dial-up circuit can be become by the integrated circuit bank of existing special-purpose dialing, also can be made up of the single-chip microcomputer that has the dual-tone dialing circuit, or add that by single-chip microcomputer the double-tone living integrated circuit that takes place frequently forms.Audio amplifier circuit can be made up of triode or audio frequency amplification circuit.Microphone device can be used loudspeaker, receiver etc.DC power supply adopts battery.

Before using this device, need desired number is deposited in the memory of dialing integrated circuit, for example the number that 300 calorie requirements are dialed is: 300820 (information desk number)+1 (or 2) (Chinese and English is selected)+* * ... * * # (18 card numbers end up with #)+* * * * (4 passwords).Because general password only has 4, more easily remember, if password also deposits in the lump,, then be easy to cause phonecard, so cryptopart does not deposit in better by free call on sb. else's expense through illegal means if this device falls into other people hand.In addition owing between different number segments, there is verbal cue (as importing card number, please input password etc., therefore between different number segments, need the joining day at interval, so that this device correctly cooperates with telecommunication apparatus.Adding two " Pause " (this is the pause function of dialing integrated circuit) through test gets final product, the number that need deposit in is like this: 300820+Pause+Pause+1 (or 2)+Pause+Pause+ * * ... * * # (18 card numbers and with the # ending), this number can exist in " Redial " memory of the integrated circuit that dials.Concrete time-division number storage and the number of using transferred to two steps, and be as follows respectively:

1) number storage step:

A. K switch is got to " ON " position by at ordinary times " OFF ".

B. keypad 300820+Pause+Pause+1 (2)+Pause+Pause+ * * ... (18 card numbers also for * * #

With the # ending)+Redial.

C. K switch is got to " OFF " position from " ON ", required number deposited Save (or Redial) in and deposited this moment

In the storage.

2) number is transferred to step:

A. K switch is got to " ON " from " OFF ".

B. the cleaner handgrip that picks up the telephone is aimed at this device vocal hole and is pushed down the handle microphone aperture, presses the Redial key, then deposits

The number of storage will disposablely be transferred to.

C. after hearing " please input password ", import password.

D. when hearing " requesting desired number ", the input called number can be conversed behind the connection circuit.

This shows that this device can be Entered Number voluntarily by the user, so number can not revealed.And easy to use, if also deposit password in this device in the lump in advance, then once can finish whole operations, unique number that has only the other side that needs input.In addition, this installation weight is light, also can be designed to the key chain pattern, and is easy to carry; Also can be designed to various animal-shaped and colors, increase its interest.Also can adopt the dialing integrated circuit or the single-chip microcomputer of band LCD interface, be designed to dialing mechanism, be more convenient for using with liquid crystal display.Also can use the dialing integrated circuit with a plurality of memories, then a device can store many sets of numbers simultaneously.This device also can be used for the occasion that other need Enter Number except that being used for circuit communication.
