Problems solved by technology

[0030] However, if Figure 15 As shown, the printing paper 20 that has been printed on the printing surface 20c is in and Figure 14 When moving in the opposite direction to the arrow K direction, since the printing surface 20c of the printing paper 20 is in sliding contact with the upper surface of the printing paper guide part 115e of the ink ribbon cassette body part 115, if the printing paper 20 is misaligned in the width direction When the paper is fed in some cases, part of the printing surface 20c may be wiped off, making the printing quality deteriorate.
[0031] In addition, in recent years, according to the needs of users, when printing on the entire surface of the printing paper 20, the printing surface 20c of the printing paper 20 is directly in contact with the upper surface of the printing paper guide 115e and is wiped off. The problem that the print quality deteriorates significantly

Abstract

The invention intends to enable proper feeding and discharging of the recording paper printed over the entire page without causing deterioration of the quality. A pair of paper guide members are disposed in the vicinity of the lateral ends of the ink ribbon (29) drawn from the ribbon outlet port (23) respectively so as to project from the wall plate (16c) of the cassette body (16) in the direction in which the ink ribbon (29) is drawn. The pair of paper guide members (35) is formed with a surface (35b) inclined in such a manner that the projecting length decreases from the projecting top to the base of the paper guide member (35) toward the lateral center of the wall plate (16c).

Description

technical field [0001] The present invention relates to a color ribbon box and a thermal printer using the color ribbon box, in particular to a color ribbon box capable of correctly feeding and discharging printing paper that has been printed on the entire surface and a thermal printer using the color ribbon box . Background technique [0002] Such as Figure 11 As shown, the conventional thermal printer 100 has a box-shaped frame 101 with a hollow inside. [0003] The frame body 101 has a side plate portion 101a on the front side, a side plate portion 101b on the deep side opposite to the side plate portion 101a, a top plate portion 101c on the upper side, and a bottom plate portion 101d on the lower side. [0004] In the cavity of the frame body 101, there is provided an ink ribbon cassette mounting portion 102 capable of mounting an ink ribbon cassette 110 described later, and an ink ribbon cassette insertion port leading to the ink ribbon cassette mounting portion 102 i...
