Description

유에스비 컨트롤러가 내장된 프린터{Printer having USB host controller}Printer with USB host controller {Printer having USB host controller}

본 발명은 유에스비(USB:Universal serial bus) 시스템에서의 출력장치에 관한 것으로서, 더욱 상세하게는 유에스비 호스트 컨트롤러(USB host controller)가 지원되는 컴퓨터가 없는 경우에도 복수의 유에스비 디바이스(USB device)를 관리하거나 유에스비 디바이스들과 데이터를 주고 받을 수 있는 프린터에 관한 것이다.The present invention relates to an output device in a universal serial bus (USB) system, and more particularly, to manage a plurality of USB devices even when there is no computer supported by the USB host controller (USB host controller). Or a printer that can send and receive data to and from the USBI devices.

일반적으로 USB 시스템은 컴퓨터의 주변기기를 용이하게 접속하는 시스템이다. USB 호스트를 중심으로 허브인 중계기를 경유하여 마우스, 프린터, 스캐너,모뎀 등의 복수의 주변기기를 용이하게 접속할 수 있다.Generally, a USB system is a system for easily connecting peripheral devices of a computer. It is possible to easily connect a plurality of peripheral devices such as a mouse, a printer, a scanner, and a modem via a relay, which is a hub, based on a USB host.

도 1에 도시된 USB 시스템의 접속구조에서 허브는, 상위 USB 호스트와 접속하기 위해 한 개의 업스트림 포트와, 하위 USB 디바이스와 접속하기 위해 복수의 다운스트림 포트를 갖는다. 즉, 허브를 이용함으로써, 한 개의 USB 호스트에 접속가능한 USB 디바이스의 수를 용이하게 증가시킬 수 있다.In the connection structure of the USB system shown in Fig. 1, the hub has one upstream port for connecting with the upper USB host and a plurality of downstream ports for connecting with the lower USB device. In other words, by using a hub, the number of USB devices that can be connected to one USB host can be easily increased.

USB 시스템에서는, 접속구조의 중심에 한 개의 USB 호스트가 존재하고, USB 호스트와 접속된 복수의 USB 디바이스들 간에 데이터의 송수신이 행해진다. 일반적으로 데이터의 전송은 USB 통신 규약에 따라 정해진다.In the USB system, one USB host exists in the center of the connection structure, and data is transmitted and received between the USB host and a plurality of connected USB devices. In general, data transfer is determined by USB communication protocol.

상기와 같이, USB 인터페이스를 갖는 종래의 전자기기에서는, USB 호스트 기능을 갖는 컴퓨터가 있고, 통신은, USB 호스트인 컴퓨터와 USB 디바이스 간에 행해진다. USB 디바이스와 USB 디바이스는 직접 통신할 수 없고, 디바이스 간에 데이터 교환하려면 필히, USB 호스트인 컴퓨터를 한 번은 경유해야만 한다.As mentioned above, in the conventional electronic apparatus which has a USB interface, there exists a computer which has a USB host function, and communication is performed between the computer which is a USB host, and a USB device. USB devices and USB devices cannot communicate directly, and must exchange via a computer that is a USB host to exchange data between them.

따라서, USB 호스트인 PC가 없는 경우, USB 디바이스간에 데이터 통신에 대한 문제점이 있다.Therefore, when there is no PC that is a USB host, there is a problem with data communication between USB devices.

예를 들어, USB 디바이스인 디지털 카메라로부터 USB 디바이스인 프린터를 통해 데이터를 인쇄할 경우, USB 호스트 기능을 갖는 컴퓨터가 없이는 인쇄가 가능하지 않다. 최근에는 별도의 전용 USB 호스트를 이용하여 디바이스간의 통신을 제어할 수도 있다. 그러나, 이 경우에는 다른 USB 호스트(컴퓨터)로부터 USB 디바이스(디지털 카메라 및 프린터)를 사용한다면, 케이블을 다시 연결할 필요가 있다.For example, when printing data from a digital camera as a USB device via a printer as a USB device, printing is not possible without a computer having a USB host function. Recently, a separate dedicated USB host can be used to control communication between devices. In this case, however, if you use USB devices (digital cameras and printers) from other USB hosts (computers), you need to reconnect the cables.

상기와 같은 문제점을 해결하기 위한 본 발명의 목적은, 출력장치에 USB 호스트 기능을 부여함으로써 USB 호스트 기능을 갖는 컴퓨터가 없이도 USB 디바이스 간의 데이터 교환을 가능하게 하는 프린터를 제공하는 것이다.An object of the present invention for solving the above problems is to provide a printer that enables data exchange between USB devices without a computer having a USB host function by giving a USB host function to the output device.

상기 목적을 달성하기 위해 본 발명에 따른, 프린터는 유에스비 디바이스로부터 데이터를 송수신하기 위한 유에스비 인터페이스; 상기 유에스비 디바이스로부터 전송된 상기 데이터를 송수신하도록 상기 유에스비 인터페이스를 제어하는 유에스비 컨트롤러; 및 상기 유에스비 컨트롤러에 의해 제어되어, 상기 유에스비 인터페이스를 통해 수신된 상기 데이터를 인쇄하기 위한 인쇄부;를 가지는 것을 특징으로 한다.According to the present invention to achieve the above object, the printer is a USB interface for transmitting and receiving data from the USB device; A USB controller for controlling the USB interface to transmit and receive the data transmitted from the USB device; And a printing unit controlled by the USB controller to print the data received through the USB interface.

또한, 상기 유에스비 인터페이스는, 복수의 상기 유에스비 디바이스와 연결하여, 상기 유에스비 컨트롤러에 의해 복수의 상기 유에스비 디바이스 중 어느 하나에 상기 데이터를 송수신하도록 한다.In addition, the USB interface is connected to a plurality of the USB devices to allow the USB controller to transmit and receive the data to any one of the plurality of USB devices.

이하에서는 도면을 참조하여 본 발명을 보다 상세하게 설명한다.Hereinafter, with reference to the drawings will be described the present invention in more detail.

도 2는 본 발명에 따른 프린터의 주요구성을 나타낸 블록도이다.2 is a block diagram showing the main configuration of the printer according to the present invention.

프린터는 USB 인터페이스(21), USB 컨트롤러(23), 인쇄부(25)를 갖는다.The printer has a USB interface 21, a USB controller 23, and a printing unit 25.

USB 인터페이스(21)를 통해서 복수의 USB 디바이스(31,33,35,...)로부터 데이터를 송수신한다.Data is transmitted and received from the plurality of USB devices 31, 33, 35, ... through the USB interface 21.

USB 컨트롤러(23)는 USB 인터페이스(21)를 제어하여 복수의 USB 디바이스(31,33,35,...) 중에서 어느 하나의 디바이스에 데이터를 송신하거나, 데이터를 수신한다.The USB controller 23 controls the USB interface 21 to transmit data to, or receive data from, any one of the plurality of USB devices 31, 33, 35,...

사용자 컴퓨터(PC:10)를 통해 수신된 데이터에 대한 인쇄명령이 전송되면, 인쇄부(25)는 수신된 데이터를 인쇄한다.When a print command for the data received via the user computer PC: 10 is transmitted, the printing section 25 prints the received data.

즉, 프린터는 USB 컨트롤러에 의해 연결된 USB 디바이스를 검색할 수 있으며, 연결된 복수의 USB 디바이스로 부터 데이터를 전송하거나 읽을 수 있다.That is, the printer may search for a USB device connected by a USB controller, and transmit or read data from a plurality of connected USB devices.

예컨데, USB 디바이스인 디지털 카메라(33)에 의해 촬상한 이미지 데이터를 저장할 경우, USB 컨트롤러(23)는 USB 인터페이스(21)를 제어하여 이미지 데이터를 USB 디바이스인 저장장치(HDD:Hard disk derive:31)에 저장한다.For example, when storing image data captured by the digital camera 33, which is a USB device, the USB controller 23 controls the USB interface 21 to store the image data as a USB storage device (HDD: Hard disk derive: 31). ).

한편, 저장장치(HDD:31)에 저장된 이미지 데이터를 인쇄할 경우에는 USB 컨트롤러(23)는 저장장치(HDD:31)로부터 저장된 이미지 데이터를 읽어들여 인쇄부(25)에서 인쇄하도록 한다.Meanwhile, when printing image data stored in the storage device HDD 31, the USB controller 23 reads the stored image data from the storage device HDD 31 and prints the image data.

따라서, 디지털 카메라에 의해 촬상된 이미지 데이터를 인쇄하기 위해 기존의 스마트카드(Smartcard)와 같은 저장매체를 이용할 필요가 없다.Thus, there is no need to use a storage medium such as a conventional smartcard to print image data captured by the digital camera.

상기와 같이, 별도의 USB 컨트롤러 기능을 갖는 호스트 컴퓨터가 없을 경우에도, USB 컨트롤러를 내장한 프린터에 의해 일반적인 컴퓨터 등과 같은 사용자 인터페이스를 통해서 USB 디바이스 간의 데이터 교환이 가능하게 된다.As described above, even when there is no host computer having a separate USB controller function, data can be exchanged between the USB devices through a user interface such as a general computer by a printer having a USB controller.

본 발명에 따르면, USB 컨트롤러를 내장한 프린터에 의해 별도의 USB 컨트롤러 기능을 갖는 호스트가 없을 경우에도 연결된 USB 디바이스들 간의 데이터 교환이 가능하게 된다.According to the present invention, a printer having a built-in USB controller enables data exchange between connected USB devices even when there is no host having a separate USB controller function.

이상에서는 본 발명의 바람직한 실시예에 대해서 도시하고 설명하였으나, 본 발명은 상술한 특정의 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형 실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and the present invention is not limited to the specific embodiments of the present invention without departing from the spirit of the present invention as claimed in the claims. Anyone skilled in the art can make various modifications, as well as such modifications are within the scope of the claims.
