Embodiment Construction

[0032] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0033] figure 1 is a sectional view showing the internal structure of the printer in one embodiment of the present invention. Figure 2 is a representation of figure 1 An enlarged cross-sectional view of the main part of the printing position of the shown printer and the cutting position of the recording paper.

[0034] Such as figure 1 As shown in FIG. 2 , the printer 1 of this embodiment is a printer used in an electronic cash register used in a POS system or the like. In order to print, for example, a roll-shaped recording paper S by a thermal head H The recording unit 2 is formed at the front, and the storage unit 3 for accommodating and holding the recording paper S is formed at the rear.

[0035] As shown in FIG. 2 , the recording unit 2 is provided with a thermal head H, a platen roller 20 , and a cutting device 30 . The recording paper S passes betwe...

Abstract

The printer 1 comprises a thermal head H for performing printing on a recording sheet S, a cutting device 30 capable of partially cutting the recording sheet S and a platen-roller 20 which can convey the recording sheet S in both directions of the forward direction from a printing position by the thermal head H to a cutting position by the cutting device 30 and the opposite direction thereof. After the recording sheet S is partially cut by the cutting device 30, the amount of the paper feed in the opposite direction by the platen-roller 20 is changed depending on the time when the motor for driving the platen-roller 20 stops.

Description

technical field [0001] The present invention relates to a printer and a control method for the printer, in particular to a printer with a function of partially cutting recording paper and reversely feeding the recording paper and a control method for the printer. Background technique [0002] For example, in a printer such as an electronic cash register (cash register) used in a POS system, a cutting device (cutting mechanism) that cuts the recording paper after printing on a roll-shaped recording paper by a thermal head is provided. ). [0003] The cutting device operates according to a cutting command sent from the host device to the printer, and cuts the recording paper after printing is completed, so that the recording paper can be issued as a receipt. [0004] In a printer equipped with such a cutting device, there is a certain distance between the position where printing is made on the recording paper and the position where the recording paper is cut by the cutting de...
