摘要： PROBLEM TO BE SOLVED: To prevent deviation of an angle of a recording head, caused by difference in wear rate between sliding contact parts, by using a simple constitution.
SOLUTION: This angle adjuster 1, which is provided between a main carriage 30 and a subcarriage 31, is subjected to a push-in force from a cam action part 37 integral with an angle adjusting lever 32 by making a rotating shaft part 35 serve as a rotating fulcrum, so as to be capable of rotating the subcarriage 31, equipped with a cam follower action part 38 abutting on the cam action part 37, at each predetermined angle in a predetermined direction. Materials, which constitute the sliding contact part between the cam action part 37 and the cam follower part 38 and the sliding contact part on the side of the rotating shaft part 35 and the subcarriage 31, are combined with one another so as to be equal in wear rate. A space member 60, which is made of the same material as a material for the cam action part 37, is used as the sliding contact part on the side of the subcarriage 31, which is brought into sliding contact with the rotating shaft member 35.

摘要： PROBLEM TO BE SOLVED: To provide a swing device capable of driving even a rather low output drive source by suppressing an increase in a power required for the driving of cams even if pressing forces between the cams and a cam follower part are increased. SOLUTION: In this swing device, the first cam 350 and a second cam 360 integrally rotated about a camshaft 209a are disposed with the phases thereof shifted in a rotating direction so that these cams can press, in order, the cam follower part 207 formed on a hopper lever 206 as a swing member. After the first cam 350 is rotated by a rotating angle D1 and the hopper lever 206 is rotated by a swing angle G1, the pressing of the second cam 360 and the cam follower part 206 is started. When the second cam 360 is rotated by a rotating angle De, the hopper lever 206 is rotated by a swing angle Ge. An angle ratio Ge/De is formed to be smaller than an angle ratio G1/D1.

摘要： PROBLEM TO BE SOLVED: To realize automatic switching control of a liquid injection space in a liquid injection device which has a carriage capable of switching a space between a liquid injection head and a material to be injected within the carriage. SOLUTION: It is judged whether or not a printing PG mode is designated in a printing command (step S1). If the printing PG mode is designated, it is judged whether or not a count value of a PC counter is an unfixed value (step S3). If the count value of the PC counter is an unfixed value, an AUTOPG resetting sequence is carried out (step S4). In the case where the count value of the PC counter is not the unfixed value, it is judged whether or not a value of the printing PG mode agrees with the count value of the PC counter (step S5). In the case where the value of the printing PG mode does not agree with the count value of the PC counter, an AUTOPG switching sequence is carried out until the values agree, thereby switching a PG (step S6).

摘要： PROBLEM TO BE SOLVED: To keep recording quality by firmly regulating and supporting a position at the time of recording materials to be recorded without giving stains to the materials to be recorded due to the leaked ink when the beginning and ending parts of the materials to be recorded are recorded without making the margin.
SOLUTION: A supporting part supporting the materials to be recorded of a platen from bottom is positioned within the scope between the highest upstream dot forming element and the lowest downstream dot forming element positioned on the highest upstream side in the several dots forming element array arranged one by another to a sub scanning direction and consists of several substances with the intervals of each other to the sub scanning direction. The intervals of the supporting part works as a hole receiving the ink leaked from the beginning and ending parts in printing both the beginning and ending parts of the materials to be recorded without making the margins.

摘要： PROBLEM TO BE SOLVED: To provide a gear fitting-disengaging device and a recorder having this device for restraining damage of an addendum of both gears caused when a switching gear 107 fittably-disengageably arranged to a first gear 101 contacts at the mutual addenda with the first gear 101. SOLUTION: When a gear shaft 102 of the first gear 101 and a gear shaft 108 of the switching gear 107 operate so as to approach, a distance S reduces, and a cam 110 and a cam-follower 105a are formed so as to increase a distance R. This gear fitting-disengaging device is constituted so that pressing force applied to the gear shaft 108 of the switching gear 107 at an inter-shaft distance AD for contacting both gears becomes smaller than pressing force applied to the gear shaft 108 of the switching gear 107 at an inter-shaft distance Ad for meshing both gears by driving the cam 110 by constant torque.

摘要： PROBLEM TO BE SOLVED: To maintain a proper feeding operation of hoppers and sheet feeding rollers regardless of the measurement of the width of a sheet of printing paper.
SOLUTION: A hopper for pushing up stacked sheets of paper toward the sheet feeding rollers 3 are composed of small hoppers 2a and 2b, and the small hoppers 2a and 2b are each provided with hopper springs, thereby preventing increase of pressure welding force of the sheets of paper to one sheet feeding roller 3 and preventing double feeding, even when the width of the sheet is narrow. When the width measurement of the sheet is narrow, a swinging operation of the small hopper 2b is constrained by a slide member 28 engageable with a movable edge guide 26, so that when the width measurement of the sheet is narrow, the small hopper 2b is not pressure welded to the sheet feeding roller 3, and a contact noises occurring when the small hopper 2b directly come into contact with the feeding roller 3 is prevented.

摘要： PROBLEM TO BE SOLVED: To obtain a paper discharging unit capable of executing a paper discharging operation without contacting the recording surface of a material to be recorded, and forming a certain cockling cycle without affecting the ink droplet impact accuracy. SOLUTION: A platen 14 is disposed facing a recording head 9. The platen 14 has ribs 10 elongating in the sub scanning direction formed by a certain interval in the main scanning direction on the surface facing the recording head 9. A paper discharging driving roller 20 having suction holes on the outer circumferential surface executes the paper P discharging operation according to its rotation while vacuuming the rear surface of a paper P by the suction holes. In the paper discharging driving roller 20, the suction holes are formed in the parts corresponding to the halfway positions of the two adjacent ribs 10 such that a cockling state is formed in the paper P by a certain cycle by the ribs 10 and the suction holes.

摘要： PROBLEM TO BE SOLVED: To take measures for surely preventing recurrence of fatal errors by accurately, surely and efficiently specifying generation causes of the fatal errors which make hardware elements uncontrollable. SOLUTION: A printer is provided with an error control routine which is to be carried out when an unrecoverable mechanical error (fatal error) is brought about, and is provided with means for counting a lapse time TF before the fatal error is brought about after a reference time. When the fatal error occurs, the printer writes the lapse time TF, states of all sensors of the printer and the like to an EEPROM. A time chart is formed from the lapse time TF and a printer control routine and is compared with a state of the printer when the fatal error occurs which is written to the EEPROM. An operation of the printer when the fatal error occurs can be specified accordingly.

摘要： PROBLEM TO BE SOLVED: To enable a printing paper tip end to strongly advance toward the downstream in the paper feeding direction, when the printing paper is warped between a paper feeding roller and a carrying roller on purpose or for some reason or other. SOLUTION: This paper feeding device is provided with an assist member 14 in a carrying path of paper P between a paper feeding roller 2 and a carrying drive roller 7. The assist member 14 is provided with an engaging portion penetrating the carrying drive roller 7 in the carrying direction downstream, rockably structured in a carrying direction upstream, and upwardly energized by a pressing spring 15. At the time of taking the skew of the paper P, the paper is warped between the paper feeding roller and the carrying drive roller, and the assist member is pressed down in such a way as to make the warped portion be along a tilting surface 16a of the assist member. The assist member gives the warped portion abutting force for abutting the paper tip end against the carrying drive roller 7. Therefore, the skew of the paper P is certainly removed.
