Problems solved by technology

[0005] However, as shown in the above-mentioned conventional ink ribbon cartridge, when reducing the width of the leaf spring or providing a slit in the leaf spring, there is a possibility that the residual edge of the leaf spring contacts the ink ribbon and damages the ink ribbon.
Assuming that the contact position between the plate spring and the ink ribbon is the end of the ink ribbon, although the possibility of hindering the recording is reduced, the ink ribbon is damaged, so it is not preferable.

Embodiment Construction

[0041] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0042] figure 1It is a perspective view showing the appearance of the front of the printer 10 to which the ink ribbon cassette according to the embodiment of the present invention is applied, figure 2 is a side sectional view showing the printer 10 . image 3 It is a perspective view showing the frame structure of the printer 10 .

[0043] The printer 10 is a serial dot matrix printer having a recording head 20 that selectively drives a plurality of recording wires and a carriage 21 on which the recording heads 20 are mounted. An image including characters is recorded on a recording medium (hereinafter referred to as a sheet).

[0044] Such as figure 2 As shown, if the printer 10 is roughly distinguished, it includes: a printer main body 12 constituting a recording unit, a transport unit 13, a sheet guide 14, and as figure 1 As shown, their top and bott...

Abstract

The invention provides an ink band box and recording apparatus, capable of applying the steady extraction resistance relative to an ink band in no damage way. The ink band box (50) comprises a container (53) for accommodating the ink band (51), and a leaf spring (60) and a spring bearing part (59) for clamping the ink band (51) drawn out from the container (53) and applying the extraction resistance, wherein a first contact portion and a second contact portion are formed on the leaf spring (60) contacted with the ink band (51), the first contact portion is contacted with the ink band in the width of the ink band (51) along the width direction, the second contact portion is gradually separated from the ink band (51) along the direction departing from the first contact portion to contact with the end of the ink band (51) along the width direction.

Description

technical field [0001] The present invention relates to an ink ribbon cassette and a recording device for storing an ink ribbon. Background technique [0002] Conventionally, among ink ribbon cassettes used in recording devices, there is an ink ribbon cassette having a mechanism that provides a drawing resistance to the ink ribbon to prevent the ink ribbon housed inside from slack (for example, refer to Patent Document 1). The ink ribbon cassette described in Patent Document 1 applies pull-out resistance by clamping the ink ribbon using a leaf spring. [0003] In such an ink ribbon cassette, the part that comes into contact with the ink ribbon may be worn along with the movement of the ink ribbon, and the ink ribbon may sink into the worn part, resulting in insufficient contact with the leaf spring. In this case, it is difficult to apply sufficient drawing resistance to the ink ribbon. As a countermeasure against this, for example, the plate spring is made smaller than the...
