aforesaid ink ribbon 15 not yet used is set such that thesensor section 15b at one side end section of it is adhered to thefirst reel 16, theink ribbon 15 is wound around thefirst reel 16 and thesensor section 15c at the other end of the winding terminal side is adhered to theink ribbon 15 not yet used wound around thefirst reel 16. - Then, the
sensor section 15c at the other end adhered to theink ribbon 15 wound around thefirst reel 16 is peeled off and then thesensor section 15c is drawn in theribbon drawing path 12 and then drawn out to thesecond reel 17 side. Then, theink ribbon 15 not yet used is drawn in theribbon drawing path 12. - Then, the extremity end of the
sensor section 15c drawn out to thesecond reel 17 side is adhered to thesecond reel 17. When this adhesion is carried out, since the adhesive agent adhered to the outer circumference of theaforesaid ink ribbon 15 is yet left at thesensor section 15b, it is not especially necessary to coat the adhesive agent to it. - Then, the
first case 19 constituting a part of theupper case 18 is applied to cover theribbon drawing path 12 having theink ribbon 15 drawn therearound, thefixing legs 19b of thefirst case 19 are engaged with the thirdengaging sections 11n of thelower case 11, thefirst case 19 is snap fitted with thelower case 11 and fixed there. After this setting, the pins (not shown) of thefirst case 19 are press fitted to either thefirst side walls 11g or thesecond side walls 11j of thelower case 11 by a press fitting machine or the like (not shown) and fixed there. - Then, the
second case 20 is applied to cover thefirst reel 16 and thesecond reel 17 pivotally supported on thelower case 11. Then, the firstengaging section 20c of thesecond case 20 is snap engaged with the firstengaging section 11c of thelower case 11 and the second engagingsection 20d is snap fitted with the secondengaging sections 11f of thelower case 11, respectively, and concurrently the thirdengaging sections 20d of thesecond case 20 are engaged with theengaging sections 19c of thefirst case 19 to cause the divided first andsecond cases second case 20 is removably fixed to thelower case 11 to complete an assembling of theink ribbon cassette 10 of the present invention. - The
ink ribbon cassette 10, assembled in this order, is mounted on a carriage for a thermal transfer printer (not shown), a desired image is printed on a recording paper by a thermal head (not shown) while this carriage is being moved along a platen (not shown), the take-up reel 17 is rotated to take up theink ribbon 15 already used. - Referring to Figs. 4, 5 and 6, a method for replacing the
ink ribbon 15 already used in theink ribbon cassette 10 of the present invention as described above with anink ribbon 15 not yet used will be described as follows. At first, an item in which an ink ribbon 15' not yet used but wound like a pan-cake is prepared in advance on thesecond reel 17 as shown in Fig. 6. As the reel for winding up the ink ribbon 15' not yet used therearound, any one of thefirst reel 16 and thesecond reel 17 can be similarly used. - It is assumed that the
ink ribbon 15 stored in theribbon cassette 10 as shown in Fig. 5 is an ink ribbon already used, wherein thesecond case 20 is manually pulled up to disengage the snap-engagement between thelower case 11 and thesecond case 20 and to remove thesecond case 20 from thelower case 11. - Then, the
ink ribbon cassette 10 is set such that as shown in Fig. 4, the first reel having the adheredsensor section 15b already finished in taking-up operation and thesecond reel 17 having theink ribbon 15 already used and taken up are exposed. - From this state, the
second reel 17 is manually rotated in a clockwise direction to cause all the remained portions which is not taken up of thesensor section 15b wound around thefirst reel 16 are taken up. - Then, upon stopping of the clockwise rotation of the
first reel 16, the extremity end of thesensor section 15b' of the ink ribbon 15' formed in a pan-cake shape not yet used for preparation as described above is adhered to the outer circumference of theink ribbon 15 already used and taken up on thesecond reel 17 as shown in Fig. 6. - When this adhering operation is carried out, the adhesive agent is yet adhered to the
sensor section 15b' when thesensor section 15b' is peeled off from the ink ribbon 15' not yet used, so that it is not especially necessary to coat the adhesive agent to it. - Then, the
first reel 16 is manually rotated in a counter-clockwise direction to cause theink ribbon 15 already used and taken up on thesecond reel 17 to be rewound slightly on thefirst reel 16. - During this rewinding-up operation for the
ink ribbon 15 already used, thesensor section 15b' of the ink ribbon 15' not yet used is drawn in theribbon drawing path 12 and then exposed at thefirst reel 16. - The
sensor section 15b' of the ink ribbon 15' not yet used but exposed at thefirst reel 16 is peeled off from theink ribbon 15 already used. Next, thesecond reel 17 is manually rotated in a clockwise direction and theink ribbon 15 already used and slightly rewound on thefirst reel 16 is taken up again to thesecond reel 17. - Then, as the
entire ink ribbon 15 is taken up and the rotation of thesecond reel 17 in a clockwise direction is stopped, the extremity end of thesensor section 15b of theink ribbon 15 already used and adhered to thefirst reel 16 is peeled off from thefirst reel 16, thefirst reel 16 is rotated again in a clockwise direction, thesensor section 15b of theink ribbon 15 already used is taken up on thesecond reel 17 and adhered to theink ribbon 15 already used in a pan-cake shape wound around thesecond reel 17. - Then, the
sensor section 15b of theink ribbon 15 already used is peeled off and the extremity end of thesensor section 15b' of the ink ribbon 15' not yet used is adhered to thefirst reel 16 having no adhesive agent thereon. - Then, the
second reel 17 having the ink ribbon already used, wound therearound and formed like a pan-cake is pulled out of theshaft bearing section 11a of thelower case 11 and thesecond reel 17 having the ink ribbon 15' not yet used but wound therearound with thesensor section 15b' being already adhered to thefirst reel 16 is inserted into theshaft bearing section 11a. - Then, the
second case 20 of theupper case 18 is applied to cover from above thefirst reel 16 and thesecond reel 17, snap fitted with thelower case 11 and fixed there to enable the ink ribbon already used to be replaced with the ink ribbon not yet used . - The ink ribbon already used is replaced with the ink ribbon not yet used in this way to enable the ink ribbon already used to be easily replaced with an ink ribbon not yet used without performing any complex work for drawing the
ribbon drawing section 12 for theink ribbon 15. - The description above has been made in reference to the case in which the
first case 19 is fixed to thelower case 11 by a pin press fitting and the like. However, it is also applicable that thefirst case 19 can be fixed to or removed from thelower case 11 in the same manner as that for thesecond case 20. - The ink ribbon cassette can be divided into the first case where the upper case is positioned at the ribbon drawing section and the second case having the shaft bearing sections capable of pivotally supporting the take-up reel and the supply reel. Since the second case is removably fixed to the lower case, it is possible to provide an ink ribbon cassette in which the second case is fixed to or removed from the lower case and the ink ribbon already used can be easily replaced with the ink ribbon not yet used .
- In addition, since the aforesaid second case is removably fixed to the aforesaid lower case through a snap fitting or engaging, the fixing or removal of the second case to or from the lower case can be easily carried out.
- Since the aforesaid ink ribbon already used can be replaced with the ink ribbon not yet used under a state in which the second case is removed from the aforesaid lower case, the main body case for the ink ribbon cassette already used can be utilized again and the ink ribbon cassette which is well adapted for environment can be provided at a low cost.
