Abstract: A recorder includes a housing and a key entry area, which is adjacent to the front end of the housing. The recorder also includes a recording unit for recording on a sheet of paper. The distance between the front end of the housing and the recording unit is equal to or longer than the length between the top of a cut sheet of letter size and the bottom of the print area in the cut sheet of letter size. The recorder further includes a tray fitted to the bottom of the housing to receive a sheet of paper fed from the recording unit. At least while the recorder is recording on a cut sheet of letter size being fed to the recording unit, the front end of the sheet does not protrude, through the space between the housing and the tray, from the front end of the housing. If the sheet end protruded, it would interfere with the operator's key entry operation.

Abstract: For control of static ink delivery pressure, a system and method make use of an outer chamber having a first outlet for delivery of ink to an ink printing mechanism, an inner chamber having a second outlet for delivery of ink to the outer chamber, and a pressure source that applies negative pressure to the outer chamber. The inner chamber maintains an internal negative pressure that is selected to control a level of the ink within the outer chamber relative to a height of the second outlet within the outer chamber. In particular, inner chamber maintains the ink level at a substantially constant level by replenishing the volume of ink within the outer chamber upon consumption. When ink is consumed by the ink printing mechanism, the inner chamber delivers a proportional volume of ink to the outer chamber that is sufficient to restore the ink to the desired level.
