  • Patent number: 11679608
    Abstract: Both end parts of a cord are fixed to a maintenance mounting frame, and an intermediate part of the cord is laid on a first body-side rotating member, a head-side rotating member and a second body-side rotating member. Here, when a motor is driven, the movement restriction of the cord is released and a movement of a head mounting frame is restricted, whereby only the maintenance mounting frame moves together with a maintenance part while the movement of the head mounting frame is restricted. Further, when the motor is driven, a movement of the cord is restricted and the movement restriction of the head mounting frame is released, whereby only the head mounting frame moves together with a discharge head while a movement of the maintenance part is restricted.

  • Patent number: 11590774
    Abstract: The wind velocity of the air injected by the air-blow dryers 7a, 7b is lower than that of the air injected by the air-blow dryers 7c, 7d. That is, since a large amount of moisture remains on the front surface M1 of the printing medium M passing through the air-blow dryers 7a, 7b, the printing medium M is dried while the flow of the aqueous inks is suppressed by injecting the air at a lower wind velocity. On the other hand, the moisture decreases on the front surface M1 of the printing medium M dried by the air-blow dryers 7a, 7b and the fluidity of the aqueous inks is reduced. Accordingly, the drying of the printing medium M is promoted by injecting the air at a high wind velocity to the printing medium M passing through the air-blow dryers 7c, 7d.

  • Patent number: 11453227
    Abstract: In the air-blow dryers 7a, 7b, the back surface M2 of the printing medium M is supported by the rollers 74 while the hot wind is injected from the nozzles 76u to the front surface M1 of the printing medium M. By extending the printing medium M along the rollers 74, the evaporation of the moisture can be promoted by the hot wind while the formation of creases of the printing medium M is suppressed against the influence of the temperature distribution caused by the latent heat of the moisture on the printing medium M. After a certain amount of the moisture is evaporated, the temperature of the printing medium M becomes relatively uniform. In the air-blow dryers 7c, 7d, the printing medium M is dried by injecting the hot wind to the printing medium M from the nozzles 76l and 76u from both sides.

  • Patent number: 11345174
    Abstract: The printing medium M after color printing is performed on the front surface M1 (recording surface) by the color printing unit 32 can be conveyed while the front surface M1 and the back surface M2 of the printing medium M are inverted twice by the only rollers 471 to 478 (rotary bodies) in contact with the back surface M2 (non-recording surface) of the printing medium M (inverting conveying part 47). In this way, without providing air turn bars, a time to convey the printing medium M from the color printing unit 32 to the white printing unit 33 can be secured while the printing medium M is firmly supported by the rollers 471 to 478 in contact with the back surface M2 of the printing medium M.

  • Patent number: 11215398
    Abstract: A web drying apparatus, comprises: two blower units which are arranged vertically between an upper dry path and a lower dry path disposed below the upper dry path and at least partially overlap each other when viewed from a vertical direction. One blower unit disposed on an upper side, the other blower unit disposed on a lower side. The lower end part of the one blower unit deviates from the upper end part of the other blower unit in the horizontal direction and protrudes to be lower than the upper end part in the vertical direction.
