摘要： PROBLEM TO BE SOLVED: To convey both cutform and roll paper onto the same path of conveyance, to feed roll paper without deskewing it, to perform processes matching cutform and roll paper at the completion of initial setting, particularly for reducing wasting of the roll paper. SOLUTION: When a button is operated at the completion of initial setting in Figure (a), a first paper removal routine is performed in which a paper feed roller 2 and a conveying roller 4 rotate in a forward direction to advance paper (figure (b), (b')). When the rear end of paper is sensed within a predetermined time, the first paper removal routine applied to cutform is continuously performed to continue the rotation of the conveying roller in the forward direction (Figure (c)). When the rear end of the paper is not sensed within the predetermined time, a second paper removal routine applied to roll paper is initiated in which the paper feed roller 2 and the conveying roller 4 are rotated in the reverse direction (Figure (c')).

摘要： PROBLEM TO BE SOLVED: To provide a large printer having a function of preventing a hand or finger from being caught in the vicinity of a rotational base end part of a roll paper cover. SOLUTION: The large printer has a paper feed part 30, a printing part 7 and a delivered paper stack part 8 arranged in a positional relationship of upper, middle and lower positions. A paper transfer path running from the paper feed part 30 through the printing part 7 to the delivered paper stack part 8 is formed nearly straight from a diagonally upper depth to a diagonally lower front of the printer. In this large printer, a roll paper cover 28 is set to the paper feed part 30, which has an upper base end part rotatably fitted to a frame 6 of a printer main body and is opened and closed when an inside roll paper is exchanged or the like. A cam-shaped guide member 50 is formed to a rotational base end part of the roll paper cover 28 to prevent a hand or finger from being caught between the roll paper cover 28 and the frame 6 when the roll paper cover 28 is closed.

摘要： PROBLEM TO BE SOLVED: To further improve printing operation of a printer having a stack part for recording papers arranged under a recording writing part. SOLUTION: A moving guide member 20 is arranged at a confluent point with a turn-over paper conveyance route provided with a flat paper conveyance route 8 continued on a recording writing part and a subpaper-feed roller 5 arranged therebelow. An inner guide surface 20a is smoothly connected to the flat paper feeding route 8 during recording and writing by a cam 24 for a roller release rotated in linkage with recording writing operation. This constitution suppresses push forward of a recording paper and improves printing quality, and performs further quiet recording writing operation through suppression of the generation of flipping noise.

摘要： PROBLEM TO BE SOLVED: To adjust a gap by moving a recording head up and down in parallel to a printing reference surface. SOLUTION: This apparatus is constituted so that a gap adjusting unit on a paper discharge roller shaft 8 driven by a paper feed motor is displaced toward the meshing side with an intermediate gear 20 by the transfer of a carriage 1 to a platen gap adjusting unit and one of planetary gears 17, 18 is meshed with the intermediate gear 20 by the rotary direction of the paper feed motor. Corresponding to the rotary direction thereof, a pair of guide rods 3, 4 are rotated in the same direction by the same quantity through a fan-shaped gear 25 to displace the carriage 1 in parallel to a printing reference surface.

摘要： PROBLEM TO BE SOLVED: To stabilize main scanning operation by suppressing the load variation to a carriage without using a special attaching member exerting effect on assembling properties in an ink jet printer using an ink supply tube. SOLUTION: This printer is equipped with a plurality of printing heads 5 (5a-5d), the carriage 4 reciprocally running within a printing region in a main scanning direction along with the printing heads 5 (5a-5d) and two-group ink supply tubes 7a-7d supplying the ink housed in ink cartridges 6a-6d to the corresponding printing heads. The ink supply tubes of one and other groups are attached so that ink supply ends penetrate into the carriage 4 on the side mutually opposed to the running direction of the carriage 4 to supply ink to the printing heads present at the positions separated from the penetration direction. By this constitution, the load applied to the carriage at a time of the running of the carriage is uniformized.

摘要： PURPOSE:To minimize simulated gradation and a rough appearance without deterioration of gloss quality on a printed surface by pressing an adhesive member on the printed part of paper to which data is transferred after the paper is peeled apart. CONSTITUTION:An adhesive roller 21 presses paper to which data is transferred after it is printed, on a platen 6. If a fin-like part sticks to the periphery of the adhesive roller 21, the ink is torn off S-section because of its adhesive force with the paper at C-section. Consequently, the fin-like part 1-N can be removed. In addition, when the adhesive film 22 is employed, an adhesive film holding roller is provided instead of the adhesive roller 21. Then the adhesive film 22 is pressed on the printed part of the paper using the adhesive film holding roller, and the adhesive film 22 is transported in an arrow G-direction. Thus the fin-like part also can be removed. It is also possible to cut the cost of expendables by using the adhesive film 22 repeatedly or cleaning the adhesive roller 21 for recovery and reuse.

摘要： PURPOSE:To reduce quasi-grdation and rough feeling and to improve printing quality by providing pressurizing means for deforming an ink film between recording means and peeling means. CONSTITUTION:An ink film 1 is wound on a peeling roller 10 to be peeled to peel it at a boundary between a film base material and an ink layer. Here, a pressurizing ember 9 deforms the film in a state that the ink is not completely resolidified to be mounted partly on a recording head 4. An ink layer 1-I is deformed at curvature r1 while solidifying in a melting state near the member 9, while the film base material is deformed at a curvature r2. Accordingly, when the deformation is released and resolidified, the resolidified part of the layer 1-I is deformed by the strain of r2 X theta - r1 X theta. Thus, a force necessary to peel off the ink may be small, and becomes equivalent to the reduction in the cohesive force in the ink only in a direction (f). The finlike part of the transfer dot can be reduced by this phenomenon.

摘要： PURPOSE:To enable a resistant value to be detected by a simple mechanism by a method wherein a resistant value is detected by bringing a detection member into contact with a film roll on which an ink film is wound with a resistant layer face up, and the resistant layer and the detection member are so established as to release their contact after a friction member forcing the film roll is transferred by rotation of the film roll. CONSTITUTION:When a lever 9 is forced on a film roll 4-a in order to establish a resistant value detection state, a detection brush 2 formed by a plate spring which is a resistant value detection member, is separated from a release pin 8 and comes in contact with the film roll 4-a by pressing force of resilience. Since detection brushes 2 are attached to both ends of a friction member 6, a resistant value of a resistant layer can be measured by impressing a specific voltage to the detection brushes on both sides. Under a printing state, the film roll 4-a is rotated in the arrow direction, and the friction member 6 is counterclockwise rotated. When the release pin 8 is rotated to a stopper part of a long groove of the lever 9, the detection brush 2 is forced by the release pin 8, and its contact to the resistant layer of the ink film 4 is released.
