When a user inputs predetermined information in the tape printing apparatus 1 and then starts printing, the thermal element of the print head 222 can transfer information preset by the user to the media tape 105 through the toner on the thermal tape 117 where the platen roller 108 abuts the print head 222, the thermal tape 117 is overlapped with the media tape 105 and moves at the same time, and the media tape 105 moves to the tape feed-out port 111 of the tape cassette 10.

Referring to fig. 5, during the printing process, when the media tape spool 104 pulls the media tape 105 to move, the elastic member 106 generates an elastic pressure on the second end surface b of the spool main body 1041, and under the elastic pressure, the third end surface c of the spool main body 1041 is in sliding contact with the first end surface a of the shoulder 1032, the first side wall d of the shoulder 1032 is in sliding contact with the second side wall e of the flange 1042, and the fourth end surface f of the flange 1042 is in sliding contact with the support rib 1033, so that a stable friction force, i.e., a stable tape discharging force, exists between the media tape spool 104 and the lower housing 1012 during the printing process.

Referring to fig. 8 and 9, during printing, the process of transferring the media tape may be: the media tape 105 first enters the passage between the first guide 1101 and the insertion opening wall 119 from the media tape accommodating area 102, returns to the media tape accommodating area 102 via the gap between the first guide 1101 and the second guide 1102, enters the passage between the second guide 1102 and the platen roller 108 again from the media tape accommodating area 102, is printed through the insertion opening 109, and the media tape 105 is fed out from the tape feed outlet 111 by the platen roller 108. In this process, the media tape 105 may rub against the first arc 1101a of the first guide 1101 and the second arc 1102a of the second guide 1102 due to the curvature of the path, and thus the media tape 105 may not be retracted.

At this time, the tape discharging force of the tape cassette 10 is mainly provided by the friction between the first guide 1101, the second guide 1102 and the media tape 105, the friction between the elastic member 106 and the media tape winding wheel 104, and the friction between the media tape winding wheel 104 and the core main body 103, and the three kinds of friction are basically constant in the use process of the tape cassette 10, that is, the tape discharging force of the tape cassette 10 is basically constant, so that the probability of the occurrence of poor problems such as font inclination during printing can be reduced, and the printing quality can be greatly improved.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
