The tape cassette includes at least an upper case 1 and a lower case 2, and the upper case 1 and the lower case 2 cooperate to form a discharge portion 3 and accommodating regions for accommodating a print tape 21, a media tape 22, and a carrier tape 23, respectively. Specifically, the accommodation region includes a first accommodation region 41, a second accommodation region 42, and a second accommodation region 43 (see fig. 2) where: a driving wheel 421 and a driven wheel 422 are arranged in the second accommodating area 42, and the driving wheel 421 drives the driven wheel 422 to rotate so as to convey the medium belt 22 from the driven wheel 422 to the driving wheel 421; an over-roller 431 is provided in the third housing area 43, and the carrier tape 23 and the transferred print tape 21 are adhered to form the label 24 after passing through the over-roller 431.

Specifically, referring to fig. 7, the printing apparatus includes a positioning shaft 52, a first driving shaft 53 and a second driving shaft 54, the tape cassette is installed in the printing apparatus through the positioning shaft 52, and the positioning shaft 52 is inserted into the third accommodating area 43; the first driving shaft 53 is arranged in the driving wheel 421 to provide power for the driving wheel 421; the second driving shaft 54 is inserted through the pulley 431 to power the pulley 431.

The printing apparatus further comprises a first platen roller 56 and a second platen roller 57, the first platen roller 56 and the print head 55 cooperating to transfer the printed information on the media tape 22 to the print tape 21, and the transferred media tape 22 is wound back onto the drive wheel 421; the second pressure roller 57 and the over-roller 431 cooperate to bond the print tape 21 with the printed information to the carrier tape 23 to form the label 24.

Referring to fig. 2 and 3, a partition wall 10 is provided in the discharge portion 1 to form a first passage 11 and a second passage 12 for feeding a print tape 21 and a media tape 22, respectively, in the discharge portion 1, a regulating portion 13 is provided in the first passage 11, and the print tape 21 is at least partially positioned between the regulating portion 13 and the partition wall 10. The utility model discloses a be provided with restriction portion 13 in first passageway 11, make printing tape 21 at least part be located between restriction portion 13 and the partition wall 10 to the problem that distortion or slope appear easily in the exhaust in-process of discharge portion in the printing tape of having solved current box.

By providing the partition wall 10 so that the print tape 21 and the media tape 22 are separated in the discharge portion 1, contact of the print tape 21 and the media tape 22 over a large area during feeding in the discharge portion 1 is avoided to reduce a frictional force therebetween. It will be appreciated that the first and

second channels

11, 12 are approximately equal in size in a direction perpendicular to the direction of feed of the print ribbon 21 (i.e., the up-down direction).

Specifically, the outer surface of the discharge portion 1 is provided with a groove 31, the groove 31 is recessed inward to form the restriction portion 13, and the groove 31 is used to escape the detection switch 51 of the printing apparatus. The detecting switches 51 are provided in plural, when the tape cassette is installed in the printing apparatus, the groove 31 can at least avoid one of the detecting switches 51, and the matching condition (for example, the number of the avoided detecting switches 51) of the groove 31 and the detecting switches 51 helps the user to obtain the type of the tape cassette used. In this manner, by the groove 31 formed in the outer surface of the discharging portion 1 and the regulating portion 13 formed by recessing the groove 31, not only can the detection of the type of the tape cassette used be achieved, but also the advantageous effect of preventing the printing tape 21 from being twisted or inclined during the discharging process can be achieved.

Referring to fig. 1 and 4, a groove 31 is disposed at one end of the outer surface of the discharge portion 1. Specifically, the outer surface of the discharging part 1 includes a front wall surface 32 and a bottom wall surface 33, and the groove 31 is formed at the boundary of the front wall surface 32 and the bottom wall surface 33, so that the restriction part 13 formed by recessing the groove 31 can restrict at least part of the print tape 21 to prevent the print tape 21 from being twisted or inclined during feeding.

Alternatively, the cross section of the groove 31 and the regulating portion 13 in the direction in which the print tape 21 is fed is rectangular. Generally, the center of gravity of the tape cassette will shift on both sides of the center line 34 during the continuous use of the tape cassette, and the tape cassette will slightly tilt off the center line 34 with the center of gravity, which will reduce the influence of the tilt of the tape cassette on the detection when the recess 31 is located on the center line 34. Moreover, the groove 31 can provide a larger avoidance space for the detection switch 51, has a better function of detecting falling (namely successful installation of the tape cassette), and prevents false detection caused by the contact of the groove 31 with an excessively small size on the detection switch 51. On the other hand, the restriction portion 13 in which the groove 31 is formed to be recessed inward can always secure the restriction of the print tape 21.

Referring to fig. 3 and 4, the partition wall 10 is sequentially provided with a first positioning post 101, a connecting plate 102 and a second positioning post 103 along the feeding direction of the printing tape, and the printing tape 21 is at least partially positioned between the limiting portion 13 and the first positioning post 101. specifically, the distance between the inner wall of the front wall 32 and the first positioning post 101 is L1, the distance between the inner wall of the limiting portion 13 and the first positioning post 101 is L2, and L1 is greater than L2, so that the limiting of the limiting portion 13 on the printing tape 21 is realized.

Referring to fig. 5, the first positioning column 101 is located on the center line 34 of the tape cassette, and the restriction portions 13 are disposed on both sides of the center line 34, so that when the tape cassette is used continuously, the center of gravity will shift on both sides of the center line 34, and the tape cassette will slightly tilt from the center line 34 along with the center of gravity, and the restriction portions 13 are disposed on both sides of the center line 34, so that the restriction portion 13 can always restrict the printing tape 21. Moreover, the restriction portion 13 cooperates with the first positioning post 101, so that not only is the friction between the printing tape 21 and the first positioning post 101 or the restriction portion 13 reduced, but also no twisting or tilting of the printing tape 21 occurs during the entire feeding process in the first channel 11.

Referring to fig. 6, the length of the restriction portion 13 on the first side of the center line is greater than the length of the restriction portion 13 on the second side of the center line, wherein the first side and the second side are sequentially distributed along the feeding direction of the printing tape. That is, the length of the regulating portion 13 located in the first passage 11 is reduced as much as possible to reduce the frictional force between the print tape 21 and the regulating portion 13 as much as possible.

To sum up, the utility model provides a ribbon cassette and printing device makes printing tape 21 at least part be located between restriction 13 and partition wall 10 through being provided with restriction 13 in the first passageway 11 of ribbon cassette, has solved the printing tape of current ribbon cassette and has appeared warping or the problem of slope easily at the exhaust in-process of discharge portion.
