Problems solved by technology

Therefore, especially when the amount of paper feeding during printing processing is large, it is difficult to maintain the tension of the recording paper pulled out from the roll paper stably due to the vibration of the roll paper in the storage unit, etc.
[0006] In this case, it is conceivable to stabilize the tension by increasing the stroke of the tension guide that applies tension, etc. However, in order to secure the stroke, the size of the device will increase.

Embodiment Construction

[0062] Hereinafter, examples of embodiments of the roll paper printer according to the present invention will be described with reference to the drawings.

[0063] figure 1 The inkjet printer 1 shown is a roll paper printer that performs color printing on the part of the roll paper pulled out from the roll portion using inks of various colors, and is opened and closed at the center of the front surface of the printer case 2 that covers the main body of the printer. The roll paper cover 3 is freely installed. An ink cartridge insertion opening 8 is provided laterally on the left side of the roll paper cover 3 , and the ink cartridge 4 is inserted through the insertion opening 8 to accommodate the ink cartridge 4 in the printer body. A power switch 5 , a feed switch 6 and an indicator 7 are also arranged on the front surface of the printer case 2 .

[0064] Such as figure 2 As shown, a roll paper 11 as a medium to be printed is stored in a roll paper storage unit 12 . When ...

Abstract

A paper roll printer has a paper roll compartment that stores paper roll so that it can roll with the axis of rotation transverse, and a side pressure plate inclined so that it touches part of the side of the paper roll and approaches the side with decreasing proximity to a supply roller. The paper roll transportation position of the supply roller that supplies paper from the paper roll is disposed to vertically overlap a paper roll of the maximum diameter that can be stored in the paper roll compartment. A movement limiting member that restricts movement of the paper roll horizontally and upwardly in the paper roll compartment is disposed opposite the supply roller.

Description

technical field [0001] The present invention relates to a roll paper printer that prints out a roll paper. Background technique [0002] For example, in a POS (Point-Of-Sale) system, a roll paper printer such as a receipt printer that prints on a roll of recording paper is used. [0003] As such a roll paper printer, Japanese Unexamined Patent Publication No. 2009-78414 discloses a printer which has a roll paper storage mechanism for storing roll paper, and uses the roll paper stored in the roll paper storage mechanism The recording paper pulled out is sent out by the platen roller to be printed by the thermal head. [0004] In addition, Japanese Unexamined Patent Application Publication No. 2009-269399 discloses a printer in which long strips of recording paper are placed on a tension guide located between the paper delivery position by the delivery roller and the paper delivery position by the paper delivery roller. The recording paper is conveyed in the normal direction...
