Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a personal computer and a printer, and more particularly to an auxiliary device for data transmission between the personal computer and the printer.

[0002]

[Prior art]

 In general, one personal computer is connected to one printer to print processed documents, etc., but the number of users who work simultaneously using multiple personal computers is increasing more and more, and the plural personal computers 1 are As they are located in different rooms or levels, it became necessary to build a corporate network. As shown in Fig. 1, a corporate network is constructed by attaching a network card to each personal computer and then using a T-shaped joint and an ETHERNET (R) cable 2 etc. to store data and data from each personal computer. Finally, one or a plurality of printers 3 were separately attached to the one or more personal computers to provide a printer that can be shared on a network.

[0003]

[Problems to be solved by the invention]

 This device has the following disadvantages. (A) Since the network construction uses ETHERNET (R) cables to connect those computers and printers, wiring work for the ETHERNET (R) cables is necessary, but extremely large old-fashioned architectures are required. Because the objects did not pre-fill their cable routing tubes, the cables had to be routed in an exposed form, resulting in a poor interior appearance, especially when the PCs were placed on different levels. became.

[0004] (b) If the cable for ETHERNET (R) receives an external force or is broken due to poor construction, the entire network becomes invalid and the maintenance of the cable is extremely troublesome.

[0005] This invention proposes a personal computer and a printer that can print wirelessly in one-to-one or one-to-many, or many-to-one, or many-to-many, etc. correspondence modes. The main purpose is to provide an auxiliary device dedicated to data transmission of a printer.

[0006]

[Means for Solving the Problems]

 Claim 1 of the present application, which has been made to achieve the above object, includes a pair of two auxiliary device bodies connected to one personal computer and one printer, respectively. One wireless transmission interface communication module including a microprocessor receiving module (MICRO processor Receiver) connected to the ECP interface and a launch module (transmitter) connected to the ECP interface of the personal computer is provided, and the ID code is built-in. Thus, the personal computer-to-printer using the frequency switching device can print wirelessly in a one-to-one or one-to-multiple manner, or in a plural-to-one or multiple-to-multiple manner. It is intended to be an auxiliary device dedicated to data transmission.

[0007]

[Embodiment of the invention]

 First, FIGS. 2 and 3 show an auxiliary device for data transmission of a personal computer and a printer of the present invention mainly including one auxiliary device main body 10 and one wireless transmission interface communication module 20, and FIG.

The auxiliary device main body 10 presents a box, has a storage space 11 therein, and has a connection provided on a side surface thereof for connection with a communication port of the personal computer main body 30 or the printer 40. A transmission indicator lamp 13 and a reception indicator lamp 14 on the upper surface of the port 12, respectively;

The wireless transmission interface communication module 20 including one microprocessor reception module 21, one emission module 22, one reader 23, and one transmission / reception switch 24 is provided inside the auxiliary device main body 10. The microprocessor receiving module 21 is connected to the ECP interface of the personal computer, the firing module 22 is connected to the ECP interface of the printer, and the reading device is transmitted from the ECP interface of the personal computer. The data is read and the ID code is built into the device. The transmission / reception switch 24 is separately connected to the microprocessor reception module 21 and the emission module 22, and the transmission indication lamp 13, the reception indication lamp 14, Displays the launch state or the reception state.

As shown in FIG. 4, the use of the personal computer and the printer dedicated to data transmission of the present invention configured as described above requires the use of one personal computer of the present invention separately for each personal computer and printer. Attaching a data transmission auxiliary device of the printer, specifically, connecting the connection port 12 of the auxiliary device body 10 of the present invention to the communication port of the personal computer body 30 and the printer 40, respectively, enables the use to be started. it can. The operation is as follows. After the wireless transmission interface communication module 20 built in the auxiliary device main body 10 reads the data (document or graphic) to be printed on the personal computer main body 30 by the reading device 23, the wireless high frequency emission module The signal is propagated by 22 (the transmission indicator lamp 13 located on the upper surface of the auxiliary device main body 10 starts blinking), and then the auxiliary device of the present invention located within a radius of 200 meters of the personal computer main unit 10. And the printer 40 connected thereto receives the same ID code by the microprocessor receiving module 21 (the reception indicator lamp 14 located on the upper surface of the auxiliary device body 10 starts blinking). The read signal is processed by the reading device 23 (ie, from analog to digital and from digital to analog). Log) and then print.

Therefore, a personal computer and a printer set with the same ID code can freely receive or transmit signals wirelessly if they are located within the emission range of 2000 meters. Since the ID code is set and adjusted by the module 20, the user can always print the personal computer-to-printer wirelessly in the form of one-to-one or one-to-many, or many-to-one or many-to-many.

[0012]

[Effect of the invention]

 This invention has the following effects. (B) The user can always print the personal computer-to-printer wirelessly in the form of one-to-one or one-to-many, or many-to-one or many-to-many.

(B) Since no cable wiring work is required, the user can install them by himself.
