Title: Card transmitter

Description:
BACKGROUND OF THE INVENTION  
       [0001] This invention relates to a card transmitter, particularly to one transmitting and receiving a graphic data of a card for a short distance.  
       [0002] Cards are an indispensable means for business or social activities, especially those working for expanding business for visiting retailers, distributors, makers, etc. have to carry out with him/her a large number of cards in order to contact with them in case of need. And it is quite inconvenient to find a needed card of a customer from the bundle of cards or a card book.  
       [0003] Now portable electronic appliances have become prevalent, and Palm Desk Assistants (PDA) are used for memorizing data of cards with more convenience than traditional cards. However, the data of cards have to be in advance to be recorded in a PDA before it can be used, impossible to exchange cards with others when meeting them in dealing with business matters. Moreover, a PDA can only store word data, impossible to store graphics such as a personal photo, a company logo, etc for more deep impression for a user to give a businessman.  
       [0004] A card transmitter in the present invention seems to be not yet on the market.  
       SUMMARY OF THE INVENTION  
       [0005] The purpose of the invention is to offer a card transmitter transmitting and receiving the graphic and letter data of a card in a short distance.  
       [0006] The card transmitter in the invention includes at least a receiving device, a converting module, a transmitting device, and a display. The receiving device receives transmitted signals and feeds them to the converting module. The converting module converts the received code signals into graphic data, and sends to the display for indicating the graphic and letters on its screen, or converts graphic data of an image on the screen of the display into transmittable code signals to be sent to a receiving device of another card transmitting device. The display is connected to the converting module and shows the graphic and letter data on its screen. The transmitting device transmits the code signals of a card to another card transmitter in a short distance. Therefore, a user can save many cards, not needing to carry with him/her many of them or a heavy card book, only needs a card transmitter in the invention.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
     [0011] A preferred embodiment of a card transmitter in the present invention, as shown in FIGS. 1 and 2, at least includes a receiving device  11 , a converting module  12 , a transmitting device  13  and a display  14  as main components combined together.  
     [0012] The receiving device  11  receives code signals transmitted from another card transmitter and feeds them to the converting module  12 .  
     [0013] The converting module  12  can either convert code signals coming from the receiving device  11  into graphic data to the display  14  or convert graphic data of an image of a card into code signals and sends them to the transmitting device  13 .  
     [0014] The transmitting device  13  transmits code signals coming from the converting module  12  to another card transmitter.  
     [0015] The display  14  is connected to the converting module  12  for receiving graphic data coming from the converting module  12  and indicates them on a screen.  
     [0016] The card transmitter  1  uses the display  14  for indicating the image of a card and the graphic data of the image of the card is converted into code signals by the converting module  12 . Then the code signals are sent to the transmitting device  13 , which transmits them to another card transmitter  1 ′ which receives the code signals with its receiving device  11 ′, and then the receiving device  11 ′ sends the received code signals to the converting module  12 ′, which then converts the code signals into graphic data. Then the graphic data are sent to the display  14 ′, which then indicates the graphic data on its screen, attaining effect of card transmitting.  
     [0017] However, the card transmitter  1  further always includes an operating member  15  consisting of a control switch  151 , a receive/send key  152 , and a up-and-down key  153  arranged properly on an outer surface of a case of the card transmitter  1 . Or as shown in FIG. 2, the display  14 ′ of the other card transmitter  1 ′ is a touch-type screen, with the control switch  151  fixed on an outer surface of the case of the card transmitter  1 ′, with the other keys all formed in an operation soft ware located inside the card transmitter  1 ′ and controlled with touching as used in a PDA. Then the weight and the size of the card transmitter can be decreased.  
     [0018] The card transmitter can also have written-in telephone numbers and names registered at the telephone company, such as government institutions, hospitals, clinics, commercial companies, other public places, etc. Then a use only looks for the written-n information in the card transmitter for needed telephone numbers to get it quickly, without need of searching a thick telephone directory or asking the number information via telephone, very convenient to use.  
     [0019] Signals used in the card transmitter in the invention may be transmitted by RF (radio frequency), infrared ray, or blue-tooth technology, only suitable for transmission between a short distances, say 3m-5m. As shown in FIG. 1, a connect port  16  such as a SUB (universal serial bus) is further added on an outer surface of the case of the cart transmitter  1 , connected to a PC for editing or amending the data of cards, such as personal photos, company logos scanned into a software of the PC. Then the finished data of cards may be sent through the connect port  16  to the card transmitter  1  for a user to carry with himself for transmitting.  
     [0020] The display  14  commonly indicates an image of a user&#39;s own card with his/her photo or a company logo. When a user wants to transmit a card to another person, the user handles the receive-and-send key  152  (or by touching in case of a touch-type screen) to transmit through the converting module  12  for converting the graphic data into code signals and sent out by the transmitting device  13 . Then another card transmitter  1 ′ receives the code signals sent out by the card transmitter  1 , converting them into graphic data to be fed to the display  14 ′ for indicating the image of the transmitted card image on its screen. Then the user can dispense with much trouble of carrying out many cards and also save expenditure for cards.  
     [0021] Moreover, though the display  14  is for showing the image of a card on its screen, an advertising mobile picture may be indicated on its screen when possible such as in waiting time. Then press a key can recover the picture of the card at once on the screen.  
     [0022] Another example of using the card transmitter is shown in FIG. 3. A control case  22  having a receiving device  221  and a converting module  222  is connected to a common telephone  21 . Then the card transmitter  1  can transmit code signals to the control case  22 , which receives the code signals by the receiving device  221  and converting the code signals by the converting module  222  to actuate the telephone  21  to dial a number. Then the card transmitter  1  serves as an electronic sound-frequency start telephone directory, and a user picks out a person&#39;s card and transmits code signals through the card transmitter  1  to the control case  22  to actuate the telephone so that the telephone automatically switches to automatic dial to attain card transmitting.  
     [0023] As can be understood from the above description, the card transmitter in the invention has the following advantages.  
     [0024] (1) The card transmitter can take place of the traditional card for a user to carry with, dispensing with many personal cards.  
     [0025] (2) The card tranmitter can save much expenditure for printing personal cards and also helpful in environment protection by saving a large volume of paper used for cards.  
     [0026] (3) The card transmitter can have written-in telephone numbers and names registered at the telephone company, such as government institutions, hospitals, clinics, commercial institutions, and public places, etc. Then a user only looks for the written-in information of the card transmitter to get wanted telephone numbers quickly, without need of searching a thick telephone directory or asking the number information, very convenient.  
     [0027] (4) The card transmitter can be used as an electronic sound-frequency start telephone directory, making it needless to put a telephone directory or a card book beside a telephone, and useful by picking out a needed card stored therein for directly dial the number automatically.  
     [0028] (5) The card transmitter can also functions as a calculator, utilizing the control key changed over to a calculator and then entering numerals. Then the monitor may display the result of calculation. Then a user does not need to carry a calculator with him/her.  
     [0029] While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modification that may fall within the spirit and scope of the invention.
