The present invention relates to a programmable card type telephone number generator, and more particularly, by inputting and storing a desired telephone number by the user and operating a button of a channel storing the corresponding number when calling a number. It is a device that can make a call without dialing or pressing a number button by inputting the generated dual tone into the handset.

A common method of making a call is to press the button keypad on the phone to enter the desired number or to rotate the rotary dial. However, there has been a demand for a device capable of making a call without entering a telephone number. In particular, as the number of telecommunications operators doing local, long-distance or international calls increases, users must enter their identification number, telephone number and password number in order to use the telephone through a specific telephone operator preferred by the user. The total number of digits of the telephone number to be input by the user becomes tens of digits, which makes it very difficult for the user to input the conventional telephone.

Therefore, in order to make the call more convenient, the memory-equipped CPU and DTMF generator are combined and stored in advance, and then the dual tone corresponding to the telephone number is generated through the speaker and the voice signal is input to the handset of the telephone. Has been proposed to make a call (US Pat. No. 4,882,750).

However, according to the technique of the patent document, since the size of the device is very large, there is a disadvantage in that it is inconvenient to carry and a lot of manufacturing costs, which is not practically widely used.

Accordingly, it is an object of the present invention to provide a card-type telephone number generator that is convenient to carry as small as a credit card or business card.

Another object of the present invention is to provide a card type telephone number generator which can be programmed by easily inputting a telephone number desired by a user.

It is a further object of the present invention to provide a programmable card type telephone number generator which does not affect other cards having magnetic input magnetic lines when carried by the user by providing an electromagnetic shielding layer.

And a processor unit for generating a DTMF signal according to the data stored in the memory unit, a speaker unit for generating a dual tone according to the DTMF signal, and a power supply unit built in the main body to supply power. It can be achieved by the number generator.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

1 is an exploded perspective view of a programmable card type telephone number generator according to the present invention. The main body 10 of the device of the present invention is similar in size to a credit card or a business card in the shape of a card, and the thickness is formed to be slightly thicker than this.

The main body 10 includes an inner space having a bottom surface and four sides and a ceiling surface around it, in which the components of the present invention are embedded and cover the lid 12. Although the device of the present invention is shown in FIG. 1 as having a rectangular parallelepiped shape, the design may be modified into a round, elliptical, or other free form by modifying the design. In any case, since the arbitrary shape of the figure is possible on the front and back of the main body 10, an advertisement drawing, various guide texts, etc. can be displayed here. By utilizing this, it is possible to design according to the requirements of the supplier, such as placing the advertisement of the company on the front and back of the main body while providing the device of the present invention as a promotional or paid for free.

Referring to FIG. 1 together with FIG. 2, the apparatus of the present invention includes a memory unit 52, a key input unit 54, a processor unit 50, a speaker unit 24, and a power supply unit built in the main body 10. 58). When the user instructs execution through key input, the phone number stored in the memory unit 52 is converted into a DTMF signal and sent to the speaker unit 24 under the control and data processing of the processor unit 50. The speaker unit 24 generates and outputs the dual tone as a dual tone, and the dual tone is inputted to the telephone to make a call when the user approaches the voice input unit of the telephone. The power supply unit 58 supplies power to all components including the processor unit 50 to enable operation.

In the device of the present invention, the electrical connection between the processor and the memory and other components is preferably made of a printed circuit board 36. When configured with a PCB, the device is highly reliable and reliable and can reduce failures. Therefore, the processor unit 50 and the memory unit 52 are implemented through the printed circuit board 36 of FIG. 1, and connection with other constituent members is also made through this.

In the apparatus of the present invention, the key input unit 54 is provided with a number button 20 for programming data of the memory unit 52, a programming button 22 for selecting a programming mode, and the memory unit 52. It is preferable to include a channel button 18 for controlling the operation to generate a plurality of telephone numbers of each channel by storing a plurality of telephone number data for each channel, respectively. That is, when only one telephone number is stored and reproduced, it is not necessary to store a plurality of numbers. However, in order to further improve the convenience of the apparatus of the present invention, a plurality of channels are provided.

Providing a plurality of channels divides the memory unit 52 of the present invention into a plurality of assigned channels, stores separate number data for each channel, and reproduces them in dual tones for each channel. Accordingly, the key input unit 54 includes a plurality of channel buttons 18 corresponding to the plurality of channels assigned to the memory unit 52, and the user uses a plurality of channel buttons 18 to select a desired number for each channel. You can save it and play it back.

As described above, the apparatus of the present invention employs a non-volatile memory that can not be programmed and stores a fixed number for each channel at the time of manufacture so that the user cannot program it by himself. However, the practical use of the apparatus of the present invention can be further improved by storing and using a number frequently used for each user. Therefore, it is preferable to configure the memory unit 52 of the present invention as a programmable memory (e.g., E ² PROM) and to set a programming mode so that a user can program a desired telephone number by himself.

In addition to a separate programming button 22 for selection of a programming mode, a number button 20 for inputting a number is provided. Therefore, in order for a user to program a telephone number on a channel, first press the programming button 22 and then press the number button 20 which includes the numbers 0 to 9 and the saff (#) and eye decision (*) buttons. After inputting, you can program the channel number data by pressing the channel button. Of course, the procedure of such a program can be set differently as needed.

In the device of the present invention, the channel is set to one or a plurality, and in consideration of the size of the main body 10, two to five are preferable, and it is most preferable to provide three or four channels. Although a plurality of channels may be configured to be programmable as described above, there is a case where it is necessary to configure a specific channel so that it cannot be programmed. That is, when the supplier of the device of the present invention disseminates for the purpose of advertisement, the user wants to keep his company number or his business identification number. Therefore, data of a specific channel can not be updated, and the rest of the channel can be freely programmed by the user.

On the other hand, in view of the size of the main body 10, it is substantially difficult to configure the 12 number buttons, programming buttons and a plurality of channel buttons to be pressed by hand by the constraint of the area. If it is possible to set an area where the button can be pressed over the entire outer surface of the main body, it is not preferable because it is difficult to advertise on the front and back of the main body. Therefore, the channel button 18 used when making a phone call using the apparatus of the present invention forms a pressing portion 14 on the cover of the main body 10 so that the user can press it by hand and has a relatively low frequency of use. The button 20 and the programming button 22 are configured to be pressed using the pointed tool 44 (see FIG. 3).

In order to effectively press the buttons 18, 20, and 22 formed on the main body 10, the channel button 18 has a pressing portion 14 formed on the cover 12 of the main body 10 so that the user can press it by hand. On the other hand, the number button 20 and the programming button 22 correspond to the number button 20 and the programming button 22 on the cover 12 so as to be pressed by the pointed tool through the cover 12. The through hole 16 is formed.

As shown in FIG. 3, a pointed tool capable of pressing the number button 20 and the programming button 22 through the through hole 16 is generally used for pens, pins, fountain pens, ballpoint pens, pencils, and the like. It may be used or separately provided tools of similar shape. However, any tool may be used as long as its end can push the button through the through hole 16 and the user can conveniently use it by hand.

These buttons 18, 20, 22 are elastic members, such as silicon, combined with a conductive member 40, such as carbon, which can contact the electrical contacts of the printed circuit board 36, as shown in FIG. 38). In the state in which these buttons are not pressed, the conductive member 40 is spaced apart from the contact of the printed circuit board 38 by the elastic force of the elastic member 38, and the button 18 is exceeded by the force of the elastic member 38. 20, 22, the conductive member contacts the contact and transmits an electrical signal indicating that the corresponding key is input to the processor unit 50.

Referring again to FIG. 1, the device of the present invention is provided with a battery 28 for power supply since each component electrically connected to a single printed circuit board is operated using electricity. A long life mercury battery or the like may be used as the battery 28, and in view of the long durability of the apparatus of the present invention, it is preferable to replace the battery.

A battery holder 30 is provided that can be coupled to the body 10 to secure the battery 28 to the body 10. The battery holder 30 is inserted into and detached from one side of the main body 10. Therefore, the battery holder 30 surrounds at least a portion of the battery and is coupled to the main body 10, and the locking holder 32 is formed in the battery holder 30, and the locking groove 34 is formed in the main body 10. It is formed so that the holder and the main body are mechanically coupled and fixed.

Due to this configuration, when replacing the battery 28 that has reached the end of its life, the battery holder 30 is taken out so that the new battery 28 and the holder 30 together with the locking protrusion 32 and the locking groove 34 are coupled. Slide it into the body (10). Some space is formed in the cover 12 to facilitate the separation of the battery holder 30 from the main body 10 so that a portion of the battery holder 30 is exposed and the user touches the nail or other tools. It is further desirable to provide a separating groove 33 that can disengage the holder 30.

On the other hand, the device of the present invention operates while consuming electricity, and there is a concern that a considerable amount of electromagnetic waves are radiated to the outside due to the magnet or the like included in the speaker 24. Since the device of the present invention is convenient to carry in the size of a credit card, the user is likely to store it in a purse or a handbag, and in such a case, it is possible to store other information such as a credit card or a phone card or a bank in a magnetic line. It may affect bank accounts. In order to prevent this, it is particularly preferable to further provide an electromagnetic wave shielding layer 42 surrounding the inner space of the main body 10.

As shown in FIG. 5, the electromagnetic wave shielding layer 42 is provided on both the ceiling surface, the bottom surface, and the side surfaces of the internal space of the main body 10 so as to contain all the various components of the apparatus of the present invention so that electromagnetic waves do not radiate to the outside. do. As the electromagnetic wave shielding layer, a metal layer such as copper or aluminum that prevents the passage of electromagnetic waves may be used, or may be coated with an electromagnetic wave shielding paint.

In the device of the present invention, the speaker receives the DTMF signal output from the processor unit 50 and generates an actual sound. When the user inputs the dual tone generated close to the voice input unit of the telephone, the telephone is placed (Fig. 6). However, as shown in the drawing, it is desirable to provide a speaker through-hole 26 so that the sound generated by the speaker can be easily released to the outside.

Furthermore, it is further preferable to further provide a sound collecting means 46 for collecting the dual tone generated from the speaker 24 to the voice input portion of the telephone 48. The sound collecting means 46 is to allow the dual tone from the speaker 24 to be directly input to the receiver. The sound collecting means 46 may be fitted around the outside of the slightly protruding speaker 24 or may be integrally formed in some cases. . The sound collecting means 46 is formed of rubber, synthetic resin, or the like, so that when the user is coupled to the speaker and approaches the voice input of the receiver, the sound collecting means 46 reduces the external divergence of the dual tone so that the telephone can be called reliably. The reliability of the device can be increased.

As is apparent from the above description, since the telephone number generator according to the present invention has a small size of a card type, it can be easily carried and stored in a pocket, a purse or a handbag, and stored necessary data such as a telephone number to operate the switch. This allows you to make a dual tone call to make a call. In particular, by providing a plurality of channels and at the same time by providing a convenient key input means that the user can program the desired number freely, the convenience can be increased, and the manufacturer's data is fixed for a specific channel, to follow the supplier's request. Can be. In addition, the electromagnetic shielding layer to protect the body to prevent damage to other magnetic information magnetic lines stored together, and provides a sound collecting means that can minimize the loss of the dual tone.
