A tape printing apparatus includes a feeding mechanism that feeds, a label tape in which a plurality of labels are disposed at equal intervals on a mount tape and a detection hole is provided at a position corresponding to each of the labels, a printing head that performs printing on the labels of the label tape, a sensor that detects the detection holes, a measurement feeding pitch, which is a distance between the detection hole of a first label and the detection hole of a second label, is measured based on a detection result of the sensor, and a feeding amount of the label tape after the detection hole of the second label is detected is corrected based on the measured measurement feeding pitch and a standard feeding pitch that is a distance between the detection holes in a specification of the label tape.
1 . A tape printing apparatus comprising:
a feeding mechanism that feeds, in a first direction, a label tape in which a plurality of labels are disposed at equal intervals on a mount tape and a detected portion is provided at a position corresponding to each of the labels;
a printing head that performs printing on the labels of the label tape fed by the feeding mechanism;
a sensor that detects the detected portions in a period in which the label tape is fed by the feeding mechanism;
a readout section that reads out a standard feeding pitch, which is a distance between the detected portions in a specification of the label tape, from a storage section; and
a feeding control section that controls the feeding mechanism, wherein
when printing is performed on the plurality of labels, the feeding control section measures a measurement feeding pitch, which is a distance between the detected portion of a first label that is any one of the plurality of labels and the detected portion of a second label to be printed after the first label, based on a detection result of the sensor, and corrects a feeding amount of the label tape after the detected portion of the second label is detected, based on the measured measurement feeding pitch and the standard feeding pitch.
2 . The tape printing apparatus according to claim 1 , wherein
the sensor is provided in the first direction with respect to the printing head,
the detected portions corresponding to the labels are provided on the label tape in the first direction with respect to positions of end portions of the labels in the first direction, and
the feeding control section repeats, for each label, calculation control of calculating a feeding correction value based on the measurement feeding pitch and the standard feeding pitch, and correction control of correcting the feeding amount of the label tape in at least a part of a period after the detected portion of the second label is detected until printing of the second label or a third label to be printed after the second label is started, by using the calculated feeding correction value.
3 . The tape printing apparatus according to claim 2 , further comprising:
a printing control section that controls the printing head to perform printing in the same printing target area in each of the labels when printing is performed on the plurality of labels, wherein
in the correction control, the feeding control section corrects the feeding amount of the label tape in a period after the detected portion of the second label is detected until printing of the second label is started, when a first distance, which is a distance between the detected portion on the label tape and a printing start position that is an end portion of the printing target area of the label in the first direction, is longer than a second distance, which is a distance between the sensor and the printing head, and corrects the feeding amount of the label tape in a period in which printing is not performed in a period after the detected portion of the second label is detected until printing of the third label is started, when the first distance is equal to or shorter than the second distance.
4 . The tape printing apparatus according to claim 2 , further comprising:
a cutting mechanism that cuts the mount tape of the label tape in a tape width direction, wherein
the sensor is provided between the printing head and the cutting mechanism.
5 . The tape printing apparatus according to claim 1 , further comprising:
a cartridge mounting section on which a tape cartridge that accommodates a tape roll around which the label tape is wound and a platen roller that feeds the label tape is detachably mounted, wherein
the feeding mechanism includes a platen drive shaft with which the platen roller is engaged.
6 . The tape printing apparatus according to claim 1 , wherein
a tape type detection section that detects a type of the label tape, and the storage section that stores the type of the label tape and the standard feeding pitch in association with each other are provided, and
the readout section reads out the standard feeding pitch corresponding to the type of the label tape detected by the tape type detection section from the storage section.
7 . A control method of a tape printing apparatus including:
a feeding mechanism that feeds, in a first direction, a label tape in which a plurality of labels are disposed at equal intervals on a mount tape and a detected portion is provided at a position corresponding to each of the labels;
a printing head that performs printing on the labels of the label tape fed by the feeding mechanism;
a sensor that detects the detected portions in a period in which the label tape is fed by the feeding mechanism; and
a readout section that reads out a standard feeding pitch, which is a distance between the detected portions in a design of the label tape, from a storage section, the control method comprising:
causing the tape printing apparatus to, when printing is performed on the plurality of labels, measure a measurement feeding pitch, which is a distance between the detected portion of a first label that is any one of the plurality of labels and the detected portion of a second label to be printed after the first label, based on a detection result of the sensor, and correct a feeding amount of the label tape after the detected portion of the second label is detected, based on the measured measurement feeding pitch and the standard feeding pitch.
