PURPOSE:To relax the variation of pressure in case of the adjustable speed of a recording head in a fluid injector by interrupting a fluid flow path by moving or bending a sheet when the head is accelerated or decelerated. CONSTITUTION:When the head 1 approaches near a left end, force is applied in the left direction from the right, and the sheets 9, 10 are strained so that the left side is convexed. The sheet 10 clogs an opening 5 at that time, and the flow path of a liquid is interrupted. The flow path is interrupted when force works in an adjustable-speed section, but the flow path is interrupted and the fluid may not be supplied because recording is not executed normally in the section. The variation of pressure propagated to the head 1 can be prevented by interruption the flow path. Consequently, the fluid supply element 4 may be arranged near the head 1 as much as possible. The effect of the fluid supply element 4 is increased because liquid chambers 13, 14 fill the roles of dampers. When the head 1 is positioned near a right end, the sheet 9 is convexed to the right side to clog the opening 5 because force is applied in the right direction from the left, and the flow path is interrupted. Accordingly, the variation of pressure is not transmitted to the head 1. |
