Title: Image recorder
Inventor: SASAKI YOSHIHARU
IPC: B41J13/22
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To reduce blur due to floating and defect due to dust of a recorded image by employing a suction source combining an air blower and a vacuum pump as a suction mechanism for securing a recording medium to a rotary recording drum. SOLUTION: When a suction mechanism is started, a suction switching control section 6 opens a solenoid valve 4 to start suction through an air blower 1. Atmospheric pressure prevails in a rotary drum 10 at the start of suction, but a recording medium can be sucked to the surface of the drum 10 even under a state where the recording medium as draped by suction force of the air blower 1. The control section 6 monitors detection value of a flow sensor 5 from that state and opens a solenoid valve 3 to start suction through a vacuum pump 2 while simultaneously closes the solenoid valve 4 to stop suction when the detected value drops below a specified level. Consequently, a high vacuum is reached and the space between the recording medium and the drum 10 is sucked powerfully and disappeared.  The recording medium is thereby held tightly at a specified position on the surface of the drum 10, thus ensuring stabilized image recording.
