Abstract

본 발명은 진공흡입식 기록매체 홀딩장치를 구비한 프린터에 관한 것으로, 종래의 프린터는 기록매체(P)가 롤러(6)와 대전기(5)에 의해서만 전사드럼(4)에 밀착되므로 고속운전시 정확한 화상의 전사를 실시하지 못하게 되고, 전사드럼(4)에서 기록매체(P)를 분리시키는 별도의 장치가 필요하여 장치의 구성이 복잡하고, 생산비가 향상되는 등의 문제점이 있었는 바, 전사드럼에 진공흡입장치와 기록매체감지센서를 설치한 본 발명을 제공하여 진공흡입원리를 이용하여 기록매체를 드럼에 확실하게 부착시킬 수 있도록 함으로써 고속으로 기기를 사용할 때에는 정확한 화상의 전사가 가능해지는 효과가 있고, 드럼상에서 기록매체를 분리할 때에 별도의 분리장치가 배제되어 기기가 간소화되며, 제조비용이 절감되는 효과가 있는 것으로, 프린터 뿐만 아니라 전사 드럼상에 기록매체를 흡착시키는 제품 일반에 적동가능하도록 한 것이다.The present invention relates to a printer having a vacuum suction type recording medium holding device. In the conventional printer, the recording medium (P) is in close contact with the transfer drum (4) only by the roller (6) and the charger (5). There was a problem in that the transfer of the accurate image was not performed, and a separate device for separating the recording medium P from the transfer drum 4 was required, resulting in a complicated configuration of the device and an increase in production cost. The present invention is provided with a vacuum suction device and a recording medium sensing sensor in the present invention, so that the recording medium can be reliably attached to the drum by using the vacuum suction principle. When the recording medium is separated from the drum, a separate separation device is excluded, thereby simplifying the device and reducing manufacturing costs. D) It is possible to adapt it to the general product which adsorbs the recording medium on the transfer drum.
