Description

Auxiliary tape cassette and tape cassette for printing Technical Field The present disclosure relates to an auxiliary tape cassette and a tape cassette for printing. Background In a printing apparatus that prints on a printing tape, the replacement and supply of the printing tape are performed by attaching and detaching a cartridge that houses the printing tape to and from a printing apparatus main body. As such a cassette, a cassette in which an ink ribbon cassette accommodating an ink ribbon and a print tape cassette accommodating a print tape are stacked is known (see patent document 1). Prior art literature Patent literature Patent document 1 Japanese Kokai publication Sho-63-156762 Disclosure of Invention Problems to be solved by the invention In the above-described cassette, printing is performed in a state in which the printing tape discharged from the printing tape cassette overlaps the ink ribbon in the ink ribbon cassette. In this case, if the path of the printing tape to the ink ribbon cassette is not properly set, the printing tape may not be properly transported due to the tape twisting or the like. An object of an aspect of the present disclosure is to provide an auxiliary cassette and a printing cassette capable of properly conveying a printing tape. Means for solving the problems An aspect of the present disclosure is an auxiliary tape cassette including a roll of auxiliary tape for printing on a printing tape to be transported, and a case accommodating the roll. The housing has a discharge port for discharging the printing tape from the inside of the housing to the outside, and a guide surface provided on the inner surface or the outer surface of the housing for guiding the printing tape supplied from the outside of the housing toward the discharge port. The printing tape is wound on the guide surface so as to form a spiral portion having a rotation angle of 180 DEG or more around a central axis parallel to the winding axis of the roll. The guide surface has a curved surface that guides at least a part of the spiral portion at an upstream side in the discharge direction of the printing belt than the discharge port. According to this configuration, the guide surface of the auxiliary cassette suppresses the occurrence of defects such as twisting of the printing tape that is conveyed to the head opening. Thus, the printing tape can be properly conveyed toward the head opening provided in the auxiliary cassette. Another aspect of the present disclosure is a tape cassette for printing, including a roll of a tape for printing and a case for housing the roll. The housing has a discharge port for discharging the printing tape to the outside of the housing and a guide surface for guiding the printing tape discharged from the discharge port. The printing tape is wound on the guide surface so as to form a spiral portion having a rotation angle of 180 DEG or more around a central axis parallel to the winding axis of the roll. According to this configuration, the guide surface of the printing tape cassette suppresses the occurrence of defects such as twisting of the printing tape that is fed to the external printing unit. Thus, the printing tape can be appropriately conveyed toward the head opening provided in the auxiliary cassette, for example. Another aspect of the present disclosure is a tape cassette for printing, including a roll of a tape for printing and a case for housing the roll. The case has a connection surface intersecting the winding axis of the roll and a discharge port provided on the connection surface and discharging the printing tape to the outside of the case in a direction intersecting the connection surface. According to this configuration, by discharging the printing tape from the discharge port provided on the connection surface of the casing, the printing tape can be appropriately conveyed toward the head opening provided in the auxiliary cassette, for example.
