ツト。[Scope of Claim for Utility Model Registration] 1. A case in which a ribbon storage section, a ribbon delivery path, and a ribbon reception path are integrated; most of the ribbon storage section is stored in a folded state; In the ink ribbon cassette, the ink ribbon cassette is equipped with an endless ink ribbon that circulates around the inside of the case through a ribbon storage section and a ribbon receiving passage, and a running mechanism that grips and runs the ink ribbon in a ribbon storage section, wherein the running mechanism is connected to a drive source. It has a driving gear and a driven gear supported by a displaceable supporting member, and one end is locked to the case on the back side of the supporting member, and the other end is in contact with the supporting member to press the driven gear toward the driving gear. The distance between the support member on which the spring is arranged and the stopper that comes into contact when the support member is displaced in the opposite direction of the spring is the distance between the center of rotation of the driven gear that meshes with the drive gear with the ink ribbon sandwiched therebetween, and An ink ribbon cassette characterized in that the distance is smaller than the distance from the rotation center of a driven gear at a biting limit position to the ink ribbon cassette. 2. A case in which a ribbon storage section, a ribbon delivery path, and a ribbon reception path are integrated; most of the ribbon is stored in the ribbon storage section in a folded state, and a portion passes through the ribbon delivery path, printing section, and ribbon reception path to the case. In an ink ribbon cassette, the ink ribbon cassette is equipped with an endless ink ribbon that circulates inside the cassette, and a running mechanism that grips and runs the ink ribbon in a ribbon storage part, wherein the running mechanism includes a drive gear connected to a drive source and a displaceable support member. A spring is disposed on the back side of the support member, one end of which locks with the case and the other end of which abuts against the support member to press the driven gear toward the drive gear. The distance between the center of rotation of the driven gear that engages with the drive gear with the ink ribbon in between and the stopper that comes into contact when the driven gear is displaced in the opposite direction of the spring's pressure is the distance between the center of rotation of the driven gear that is engaged with the drive gear with the ink ribbon in between, and the distance between the center of rotation of the driven gear that is engaged with the drive gear with the ink ribbon in between, and the distance between the center of rotation of the driven gear that is engaged with the drive gear with the ink ribbon in between, and the distance between the center of rotation of the driven gear that is engaged with the drive gear with the ink ribbon sandwiched between An ink ribbon cassette characterized by being smaller than the distance from the center of rotation of the gear.
