FIG. 6 is a diagram showing a table T prestored in the control device 50. As shown in FIG. In the table T, the material of the wrapping paper 62, the rotation speed, the first heat generation amount, and the second heat generation amount are associated with each other. The rotational speed corresponds to the rotational speed of the driving roller 41a. The first heat generation amount corresponds to the heat generation amount per unit time of the printing heating element 42a. The second calorific value corresponds to the calorific value per unit time of the welding heating element 43a. The values stored in the columns of rotational speed, first calorific value, and second calorific value are determined in advance by actual measurement through experiments or the like and stored.

Specifically, the value stored in the rotation speed column is based on the characteristics of the material of the wrapping paper 62 (for example, tensile strength), and the speed at which the wrapping paper 62 is conveyed by the driving roller 41 a and the driven roller 41 b. The rotational speed of the drive roller 41a is set such that the forces acting on the paper 62 do not tear the wrapping paper 62 from the perforations.

In addition, the value stored in the column of rotation speed is set to the rotation speed of the drive roller 41a at which the wrapping paper 62 is conveyed at a speed at which the printing in the printing unit 42 does not shift. The value stored in the column of rotation speed is a drive roller that provides a relatively high transport speed within the range of a transport speed at which the wrapping paper 62 is not torn from the perforations and a transport speed at which print deviation does not occur. 41a.
