  • Publication number: 20220281129
    Abstract: A cutting device decides a cutting pressure correspondence value corresponding to a pressure applied to a mounting portion of a cutting blade when cutting an object to be cut using the cutting blade based on a first pressure correspondence value corresponding to the pressure applied to the mounting portion when it is detected that the cutting blade has come into contact with the object to be cut in the course of the mounting portion, and on a second pressure correspondence value corresponding to the pressure applied to the mounting portion when it is detected that the cutting blade has reached a holding surface of the holding member of the object to be cut. A cutting device applies the pressure to the mounting portion based on the cutting pressure correspondence value and cuts the object to be cut using the cutting blade mounted to the mounting portion.

  • Patent number: 9868308
    Abstract: A controller performs: correcting a pre-correction pulse signal and outputting the corrected pre-correction pulse signal as a post-correction pulse signal that switches between third and fourth levels, the correcting including: switching the post-correction pulse signal from the third to fourth level when first or second condition is satisfied, the first condition being that the pre-correction pulse signal switches from the first to second level, the second condition being that duration of the third level exceeds a first reference period; and switching the post-correction pulse signal from the fourth to third level when both of third and fourth conditions are satisfied, the third condition being that duration of the fourth level exceeds a second reference period, the fourth condition being that the pre-correction pulse signal is on the first level; and calculating a relative moving velocity of the moving device based on temporal changes between the third and fourth levels.

  • Patent number: 9334132
    Abstract: A recording apparatus includes: first and second recording modules; a storage accommodating a recording medium; a first path extending from the storage to the first recording module; a second path extending from the storage to the second recording module and including a first shared portion shared with the first path; a first roller pair disposed downstream of a branch position on the first path; and a second roller pair disposed on the first shared portion. The controller is configured to: determine whether a trailing edge of the recording medium on which recording is being performed by the first recording module is located downstream of the first roller pair on the first path; and when the trailing edge is located downstream of the first roller pair on the first path, cause the second roller pair to supply a recording medium from the storage to the second recording module.

  • Patent number: 9272545
    Abstract: In a recording apparatus, a first path and a module path of a first recording module for conveying and recording of a recording medium are formed such that a distance between the most downstream ejection opening and a joining position of the first path and a second path is less than a length of a recording medium. The controller executes: a first determination processing for determining whether there is a recording medium which should be conveyed through a join determination position before the recording medium having been supplied to the first recording module; and a wait processing for causing the recording medium having been supplied to the first recording module to wait in a state in which its leading edge is located upstream of the most upstream shared conveyor on the first path, when the controller determines that there is a recording medium.
