Abstract: A shift register includes stages each constituted by a unit circuit provided with a thin-film transistor (separation transistor) that separates a control node into an output-side first control node and an input-side second control node and a capacitor whose first end is connected to the second control node. The thin-film transistor (separation transistor) has a control terminal that is supplied with a high-level DC power supply voltage. Typically, the channel width of a thin-film transistor (first output control transistor) that controls output from a unit circuit is ten or more times greater than the channel width of the thin-film transistor (separation transistor).

Abstract: The disclosure discloses a printer including a memory. The memory stores computer-executable instructions that, when executed by a processor, cause the printer to perform a first process, a second process, and a third process. In the first process, an N-th determination target value is calculated, from an N-th pulse count index value and an (N+1)th pulse count index value. In the second process, a mean value of a plurality of consecutive pulse count index values within a predetermined range is calculated. In the third process, a comparison value is calculated by comparing (N?1)th the determination target value with the mean value. The first process to the third process are performed while increasing N one by one. A first determination step includes determining whether the elongated medium has reached a consumption completion status or not, on the basis of a magnitude relation between the comparison value and a first threshold value.
