    • PURPOSE:To make feed rate and winding quantity equal at a given period of time, by installing a movable body, coming into contact with board, in a route leading to a winding part from a printer part, interlocking with the operation, and opening or closing an interval between a winding motor and a power source in a selective manner. CONSTITUTION:A box 8 is installed in front of a label printer 1, and there are provided with a winding motor 9 and a winding shaft 10. Likewise in the side, there is provided with a movable body 13 which is energized downward with its own weight and rotable in both upper and lower directions. This movable body 13 consists of an arm 15 and cams 16 and 17 rotating solidly together with a fulcrum shaft 14, and a bar 18 being situated at an arm tip and bending a route of board 5. Also there are provided with switches 21 and 22 which have switches 21 and 22 elastically coming into contact with each outer circumference of these cams 16 and 17. Therefore, a difference between fees rate and winding quantity is equalized at a given period of time because these switches 21 and 22 are operated by rotation of cams 16 and 17 due to vertical motion of the movable body 13, so that it is unnecessary to synchronize both operations of a feeding part and a winding part.

    • PURPOSE:To form a bar code consisting of small-width and large-width bars having widths conforming to specifications in the state of being free of black or the like, by setting a paper feed quantity for each line to a predetermined value so that printing by heat generating elements is conducted with a predetermined overlap length provided for each line in a paper-feeding direction, in a serial-type bar code printing method. CONSTITUTION:Printing by heat generating elements 4 is conducted with a predetermined overlap length l=65mum provided for each line in a paper-feeding direction. Fig. (a) illustrates a printing operation for each line, for the leftmost heat generating element 4 of a thermal head 5. The printing is so conducted that the width W1 of a small-width black bar 7 formed by printing a series of 2 dots is 0.375mum, the width W2 of a large-width black bar 8 formed by printing a series of dots is 1.1250mum, the width W3 of a small-width white bar 9 formed by not printing a series of 3 dots is 0.400mum, and the width W4 of a large-width white bar 10 formed by not printing a series of 8 dots is 1.175mum.
