The threading assembly 3 is arranged in the accommodating cavity 23.

When the tape cassette is loaded into the label printing apparatus, the mechanical sensor unit 12 detects the type of the tape cassette, such as the ground color, the character color, etc., by contacting the first detecting portion 211; the optical sensor unit 13 emits light to the label tape inside the cartridge 2 through the second detection port 221a and receives reflected light to detect label tape related information such as opening start information, printing end information, and the like.

This application is with second detection mouth 221a and first detection mouth 211a intercommunication, and then allows the ray path of optical sensor unit to have certain upper and lower scope, and when the box upwards floated, the condition that the lateral wall of box body disturbed the light transmission can not appear, avoided the false retrieval.

Specifically, the tape cassette further includes an arm 4, the arm 4 is provided at one side of the cassette body 2, integrally formed with the cassette body 2, and a long hole opening 5 is provided between the arm 4 and the cassette body 2, so that a print head of the label printing apparatus can penetrate into the long hole opening 5 and then print at the long hole opening 5 by heating the print head. The arm 4 includes an outer wall 41, a partition wall 42, and an inner wall 43, a first threading passage 44 is formed between the outer wall 41 and the partition wall 42, and a second threading passage 45 is formed between the partition wall 42 and the inner wall 43. The tape passing assembly 3 comprises a label tape roll 31, a limiting wall 32, a limiting pin 33, a carbon tape roll 34, a winding wheel 35 and a tape discharging assembly 36. During assembly, the label tape roll 31 and the carbon tape roll 34 are respectively arranged in the accommodating cavity 23, and the label tape roll 31 and the carbon tape roll 34 are respectively arranged in the corresponding support holes 20; the limiting wall 32 and the limiting pin 33 are respectively arranged in the accommodating cavity 23, the winding wheel 35 and the tape discharging component 36 are respectively and rotatably arranged in the accommodating cavity 23, the winding wheel 35 and the tape discharging component 36 are respectively arranged in the corresponding supporting holes 20, and one end of the carbon tape on the carbon tape roll 34 is connected with the winding wheel 35.

During printing, the label tape on the label tape roll 31 is guided by the limiting wall 32 and the limiting pin 33 to penetrate into the first tape passing channel 44, and then guided by the first tape passing channel 44 and the tape discharging assembly 36 to be discharged from the tape outlet. The carbon tape on the carbon tape roll 34 is guided by the second tape passing path 45 to move toward the winding wheel 35 and is wound by the winding wheel 35. The thermal transfer ribbon is overlapped with the label ribbon at the slot opening 5 and is transferred by the print head.

The mechanical sensor unit 12 includes a plurality of projections 122, and the first detection port 211a communicates with the cavity in the arm portion 4, exposing a part of the label tape in the cartridge; the second detection port 221a communicates with the cavity in the arm 4, exposing another portion of the label tape in the cartridge.

When the tape cassette is loaded in the label printing apparatus, in the light sensing process, light is emitted from the emitting element 131, enters the tape cassette from the second sensing port 221a, is irradiated on the label tape, is reflected by the label tape, enters the receiving element 132 through the first sensing port 211a, and has black marks for sensing arranged at predetermined intervals, and during printing, the label tape travels through the passage between the outer wall 41 and the partition wall 42, passes through the position of the first sensing port 211a of the first sensing portion 211, and at this time, the mark portion and the non-mark portion on the label tape alternately receive light sensing, and reflect different amounts of light to the receiving element 132. When the receiving element 132 receives the amount of light reflected at the mark, a specific signal is output, whereby the printing apparatus performs a predetermined operation. In the mechanical sensor detection process, a part of the convex part 122 presses the outer surface of the detection piece 211b to form a pressing state, a part of the convex part 122 extends into the first detection port 211a to form a non-pressing state, so that the mechanical sensor unit 12 is matched with a contact part or a non-contact part of the tape cassette, different state combinations of the convex parts 122 occur, different electric signals are formed in the printing device, and the type information of the tape cassette, such as ground color, character color and the like, is detected

As the tape cassette is used, the label tape is used and the winding wheel winds the used carbon tape, the overall weight and the center of gravity of the cassette body gradually change, resulting in a risk of a shift in the printing position of the tape cassette. The horizontal shift of the tape cassette is limited by the support shaft and the rotation shaft in the printing apparatus, but the shift of the black mark in the tape cassette in the vertical direction cannot be completely avoided (shift due to a change in the center of gravity caused by a gap between the label and the housing or a decrease in the mass of the tape cassette).
