  • Patent number: 11951744
    Abstract: A switching mechanism includes a first rotating body that performs forward rotation and reverse rotation by receiving a driving force transmitted from a driving source; and a second rotating body having convex portions provided on an outer circumference at intervals. The first rotating body has an engagement portion configured to move along the outer circumference of the second rotating body. When the first rotating body rotates in a forward direction, engagement of the engagement portion with the convex portion causes rotation of the second rotating body in the forward direction together with the first rotating body. When the first rotating body rotates in a reverse direction, the engagement portion moves along the outer circumference of the second rotating body so that the second rotating body does not rotate in the reverse direction. A first interval, which is at least one of the intervals, is larger than other intervals.

  • Patent number: 11951735
    Abstract: A printing device includes: a printing unit printing on a recording paper; a feeder unit having a roller that rotates about a shaft and feeds the recording paper and a motor that rotates the shaft; a detection unit detecting the rotation of the shaft; and a control unit controlling the printing unit. The control unit calculates an electrifying time during which the printing unit is electrified and a non-electrifying time during which the printing unit is not electrified following the electrifying time, based on a detection signal from the detection unit. When the calculated non-electrifying time is less than a predetermined time, the control unit corrects the non-electrifying time in such a way that the non-electrifying time becomes equal to or longer than the predetermined time, and causes the printing unit to print.
