摘要： PROBLEM TO BE SOLVED: To solve a problem of uneconomical replacement of a filter with contaminated hands while interrupting print operation for a long time when the filter for removing impurities, e.g. dust, in ink is clogged to increase the channel resistance of ink thus causing malfunction of the system at the time of ejecting ink for recording from the ink ejection port of a recording head through an ink cartridge or reusing ink ejected by ejection recovery. SOLUTION: The ink jet recorder comprising an ink supply passage extending from an ink storage means to a recording means and an ink recovery passage extending from a section for receiving ink ejected from an ink ejection port to the ink storage means is provided with means for varying ink pressure in the ink recovery passage.

摘要： PROBLEM TO BE SOLVED: To charge a secondary battery by automatically shifting the temperature of the battery within a range where the battery can be charged even if it is under an environment out of the range where the battery can be charged when the secondary battery provided on a power supply part of an electronic device such as an ink-jet recording device. SOLUTION: This device comprises a temperature detecting element 305 for detecting the internal temperature of the secondary battery 203, and a temperature control element 306 for controlling the temperature of the second battery 203. When the indication of charging the secondary battery 203 is transferred from an MPU 102 where the secondary battery 203 is disposed, the temperature of the second battery 203 is detected by the temperature detecting element 305. When the temperature is out of the range where the prescribed charging can be started, the temperature of the secondary battery 203 is shifted within the range where the charging can be started by the temperature control element 306 for charging.

摘要： PURPOSE:To obviate the positioning adjustment and prevent dislocation so as to improve the sheet feeding accuracy by pressing a sheet to a feed roller, disposed obliquely at a specified angle to a sheet feeding direction, by an elastic member. CONSTITUTION:A spring 14 serving as a contact means for bringing a sheet into contact with a feed roller 9 is fitted to an upper cover 13 so as to press the sheet into contact with the feed roller 9. The shaft of the feed roller 9 is disposed at a skew angle to a right-angled direction to a sheet feeding direction. A side plate 7f serving as a positioning means is formed at a lower case 7 so as to be the recording position reference of a recording part 3. When the sheet is fed in the skew state, the sheet advances toward the side plate 7f because of the skew disposition of the feed roller 9, and when the corner of the sheet comes in contact with the side plate 7f, the sheet is rotated and fed along the side plate 7f. The skew feed of the sheet is thereby prevented so as to feed the sheet accurately.

摘要： PURPOSE:To execute a recording of respective pages in accordance with an each page recording form prescribed, by setting a means executing a controlling wherein a continuous recording of respective pages is executed by respective pages recording forms set by a recording form setting means. CONSTITUTION:When a recording is executed (A001), a judgement is executed whether a recording of all pages identical form (for example, same number of sheets) is executed, or other recording than that is executed (A002). After this, if the former is executed, an effective recording form in one sentence is set, and if the latter is executed, an effective recording form in one page is set (A003), and a controlling is so executed that a recording is executed in respectively set forms (A006, A007 or A004, A005). As this recording form, a recording paper size, a recording letter size, a recording page number, a recording number of sheets, a longitudinal, a lateral, a vertical, a left or a light margin, a recording style of type and the like can be listed as its elements.

摘要： PROBLEM TO BE SOLVED: To execute high-grade recording by emitting a recording soln. during the scanning by a recording head to perform recording and providing a fixing means for fixing a recorded image and properly controlling fixing corresponding to the kind of a material to be recorded and/or a recording mode. SOLUTION: It is judged whether a standard mode is selected (step S1) and, in such a case that the standard mode is judged to be selected, a next step is executed to judge whether paper is plain paper or a postcard (step S2). In the case of YES, a next is executed to judge whether a fixing mode is set (step S3). When the fixing mode is judged to be set, a next step is executed and, a printing grade is made high, that is, a mode performed by a multi-pass recording system is automatically set (step S4). Continuously, the fixing time in such a case standard mode + fixing mode are automatically set is set (step S6) and recording according to a high grade mode lowered in recording duty ratio is executed (step S7).
