摘要： PROBLEM TO BE SOLVED: To enhance the abrasion resistance, water repellency and sliding performance without changing arrangement of each component by coating one or both of a pair of surfaces at a part to be detected with an abrasion resistant coating layer having a relatively small coefficient of friction. SOLUTION: Variation of magnetic field of a magnetic film 70 being inserted into a through part 22b in the base part of a carriage member is detected by means of a magnetic sensor 68 arranged on one side of the magnetic film 70. A magnetic layer 78 formed on the surface of the mother material layer 77 of magnetic film 70 is coated with a protective layer 79 on the side of the magnetic sensor 68. A primer layer 76 formed on the surface of the mother material layer 77 is coated with a fluororesin layer 75 on the side remote from the magnetic sensor 68. The magnetic layer 78 is bonded to the mother material layer 77 through an adhesive Ad and arranged with S and N poles alternately at a specified pole interval along the longitudinal direction. The protective layer 79 is hardened in order to ensure abrasion resistance. The primer layer 76 is formed to enhance the adhesion of the fluororesin layer 75 to the mother material layer 77.

摘要： PROBLEM TO BE SOLVED: To improve an operating quality upon mounting and dismounting of a recording head and eliminate any damage on contact surfaces of the recording head and a carriage due to misoperation or the like by making a biasing force of biasing means a part of an operating force of an operating lever when the recording head is to be dismounted. SOLUTION: Turning of a hook lever 33 causes a head holder 31 to move in rightward and leftward directions, and a biasing force of a contact spring becomes a pressing force, with which a recording head is pressed by the head holder 31 through the hook lever 33. Since a clearance X between the hook lever 33 and a hook cover in a thrust direction is set to be greater than a height Y of a cam portion of the hook lever 33, any interference is not caused between the hook lever 33 and the hook cover, which leads to no obstruction against an action of a second cam mechanism. When the recording head is to be mounted, first cam portions 316, 331 enable the recording head to abut against a positioning surface of a carriage and electrically contact with a flexible substrate.

摘要： PURPOSE:To obtain a low-cost recorder in which a structure is simplified by stacking record sheets in a stacker out of a guide member by own weight after a lower end of the sheet is passed through a discharge means. CONSTITUTION:A record sheet 10 conveyed while tension is being applied between a discharge roller 13 and a sheet feed roller 22 is discharged while being supported by a sheet discharge guide 25 provided slightly at a left side from a central axis of a lateral direction of the sheet 10 under the roller 13. The sheet 10 is not dropped to a stacker 20 where the discharged sheet 10 is stacked while being interposed between the roller 13 and a pulse wheel 14. Accordingly, the sheet 10 being discharged is not brought into contact with a recording surface of a recorded sheet 10b already stacked in the stacker 20. However, when the conveyance is advanced and the lower end of the sheet 10 is removed out of the roller 13 and the wheel 14, the sheet 10 is slid out of the member 25 by own weight of the sheet 10, dropped to the stacker 20 and stacked in the stacker 20.

CONSTITUTION:A cap 51 is provided so as to be opposite to the ink discharge port forming surface of a recording head under the state that a shiftable carriage, on which the recording head is installed, takes its home position in order to forcibly deliver the ink accepted in the cap 51 by the suction force of a pump 53. A blade 59 for wiping the discharge port forming surface of the recording head is provided. The driving of the pump 53 and the movements of both the cap 51 and the blade 59 are performed by a cam device 63. The blade 59 is mounted to a blade lever 535, which is pivotally supported about the axis 519 of the pump 53, so as to abut a blade roller 535A, which is a following-up member mounted rotatably on the lever 535, against the discharge port forming surface of the recording head in order to control blade intrusion amount.

摘要： PURPOSE:To detect ink which has leaked from a recovery system, peripheries of an ink discharge tank or the like, and give an alarm securely to prevent troubles accompanied by ink leakage by providing an ink detecting member and detecting means for detecting a state variation of the detecting member within the device. CONSTITUTION:In a substrate section in the arrangement area of a recovery system 13, tube 14, and an ink discharge tank 15, there is provided an ink sbsorber 19 of a high absorptive member such as foam polystylene, foam polyurethane or the like. When the ink discharge port 13b and tube 14 remain disconnected, ink is immediately prevented from flowing to electric parts and so forth by the ink absorber 19. In this instance, before the amount of flowing ink comes beyond the tolerance of the ink absorber 19, since a part of the ink absorber 19 is in contact with a material to be recorded, it appears on the recording paper as an ink stain, so that the operator can recognize an abnormality of the recording device.
