Abstract: A liquid jet recording apparatus is structured to enable recording liquid to circulate by conductively connecting the recording head (13) for discharging recording liquid and means for retaining recording liquid through a forwarding path (30) for recording liquid to flow into the head and a returning path (31) for recording liquid to flow out from the head. This apparatus comprises means (11,9) for generating pressure to suck recording liquid on the returning path (31) from the head (13), while exerting pressure on recording liquid in the forwarding path (30) toward the head (13). In this way, dust particles and air bubbles in ink are removed without allowing ink to flow out of the discharge ports (15) of the recording head so as to save the consumption of ink to be used wastefully when a recovery operation is executed for the apparatus.

Abstract: An ink jet printer comprises a wiper member for wiping the surface of the ink jet recording head. The ink jet recording head and the wiper member move in the same direction each other to wipe the surface of the ink jet recording head by one operation. In this way, the stabilized wiping is always possible to keep the head surface in an appropriate condition of ink discharges, hence obtaining images in beautiful print quality with the stable ink discharges.

Abstract: PURPOSE:To rewind a recording medium to enable the use thereof when a small-sized medium to be recorded is continuously used to eliminate the wastefulness of the recording medium by providing discrimination marks to the side end part of the strip like recording medium used in a thermal transfer recording apparatus at a specific interval. CONSTITUTION:When the area of one screen is small, an ink sheet 1 being a recording medium is constituted of three kinds of colors, that is, yellow, magenta and cyan and has an yellow dye part 1Y, a magenta dye part 1M and a cyan dye part 1C and is wound in a roll form to be constituted as a cartridge. In this case, the cueing sensor marks 1y1, 1m1, 1c1 are provided to the ink sheet 1 as the discrimination indexes of the respective dye parts 1Y, 1M, 1C of the ink sheet 1 and intermediate part sensor marks 1y2, 1m2, 1c2 are provided as the discrimination indexes of the dye parts 1Y, 1M, 1C. When a small-sized recording sheet is used, the ink sheet 1 is unwound to be used until the respective discrimination marks are detected by a detection means.

Abstract: PURPOSE:To prevent the unwinding of a continuous medium even when impact is applied thereon due to dropping and the like by a method wherein the wound member is provided with a first wound member, around which the continuous medium is wound, a second wound member, around which a guide member is wound, and a frame type retaining section, formed on the second wound member to retain the side rims of the continuous medium and provided with a slit formed on the peripheral surface. CONSTITUTION:A first wound member or an ink wound member 31 and second wound members or ink sheet leader wound members 34a, 34b are formed in an ink reel 30. The outer diameters of the ink sheet leader wound members 34a, 34b are made larger than outer diameters in a case when a predetermined amount of ink sheet is wound around the ink sheet wound member 31 to prevent interference between the ink sheet and the ink leader member. Further, ink leader retaining sections 35a, 35b, provided with a multitude of slits 36 for retaining the retaining part of the ink leader member on the peripheral surface of the frame type retaining sections, are formed on the outside of the ink sheet leader wound members 34a, 34b to pinch the rear end of the retaining section of the ink leader member and prevent the unwinding of the ink leader member by the own force of the same.

Abstract: PURPOSE:To carry a wound recording medium while using a second guide member as a feed reel by pulling out a first guide member by Joining the first guide member at the open end of the recording medium wound in a long-sized shape and the second guide member at a winding-side end section respectively. CONSTITUTION:An ink sheet 2 drawn out from a feed reel 30 is given constant tension. A spring 61 energizing a take-up reel driving shaft 60 in one direction is installed so as to facilitate engagement with an engaging pawl 34a mounted at one end of a pinion gear 34. When a rectangular pawl section 60a and the engaging pawl 34a are engaged, the take-up reel driving shaft 60 is slid in the longitudinal direction because there is a clearance between the end face 60b of the pawl section 60a and the end face 62b of a bearing 62 even when the rectangular pawl section 60a and the engaging pawl 34a are abutted, and the driving shaft 60 is rotated in a trace quantity in the direction of rotation, thus slipping off abutting and engaging the driving shaft 60.

Abstract: PURPOSE:To provide recording method and device, by which the reproducibility of gradation is improved and recording is enabled, by adjusting energy applied to a recording head on the basis of the temperature of the recording head and an ambient temperature where the device is positioned. CONSTITUTION:The temperature of a thermal head 103 is detected by a temperature sensor 115, and an ambient temperature where a device is positioned is detected by a temperature sensor 124. Maximum applied energy information to the thermal head is stored in a ROM table 135 in response to the temperature of the thermal head and the ambient temperature, and applied energy information corresponding to these temperature information is read from the ROM table 135. The quantity of applied energy to the thermal head 103 is determined in response to the read applied energy information, and recording is conducted.
