PURPOSE:To relax a shock to a recording form by arranging buffer members above and below a pressure transfer mechanism consisting of an image carrier and a pressuring roll and reducing the length of press-contacting between the image carrier and the pressuring roll when the recording form is rushed and ejected. CONSTITUTION:The recording form is sent between both rolls 31 and 32 of a pair 30 of buffer rolls in the direction of an arrow S, and the roll 32 is moved downward against a pressure P by this form. Then, a pressuring lever 20 is turned clockwise around a supporting shaft 21 to reduce the length of press- contacting between a drum 11 and a pressuring roll 12, and the shock for rush of the form is relaxed. The form is sent to a pressure transfer mechanism 10 to turn the lever 20 clockwise furthermore, and the pressure to the form due to the pair 30 of buffer rolls is released. Next, the front end of the form is sent between both rolls 41 and 42 of a pair 40 of buffer rolls, and the roll 41 is pressed up to turn the lever clockwise, and the length of press-contacting between the drum 11 and the roll 12 is reduced again to relax the shock for the ejection of the rear end of the form from the transfer mechanism 10. |
