Claims

[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 sandwiches and runs the ink ribbon in a ribbon storage section, wherein the running mechanism is connected to a drive source. Consisting of a driving rotor and a driven rotor supported by a displaceable support member, a movable piece is displaceably supported by a case near the back of the support member, and one end is supported by the case to prevent movement of the movable piece. and a leaf spring that transmits the motion to the supporting member, and is characterized by being provided with a pressing mechanism capable of pressing the driven rotor toward the driving rotor with the restoring force of the leaf spring generated by the displacement of the movable piece. 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 holds and runs the ink ribbon in a ribbon storage part, wherein the running mechanism includes a drive rotating body connected to a drive source and a displaceable support. Consists of a driven rotating body supported by a member, with a removable spacer near the back of the support member, one end supported by the case, the other end locked to the spacer, and the middle part can come into contact with the support member. 1. An ink ribbon cassette comprising a flat spring and a pressing mechanism that can press a driven rotary body toward a driving rotary body by the restoring force of the leaf spring generated by inserting a spacer. 3. 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 holds and runs the ink ribbon in a ribbon storage part, wherein the running mechanism includes a drive rotating body connected to a drive source and a displaceable support. Consisting of a driven rotating body supported by a member, near the back of the support member, there is a leaf spring whose both ends are held by a displaceable fixture and whose one side can come into contact with the support member, and a removable leaf spring adjacent to the fixture. A pressing mechanism is disposed that can press the driven rotor toward the driving rotor using the restoring force of the leaf spring generated when the fixing device and the leaf spring are displaced toward the support member by inserting the spacer. An ink ribbon cassette featuring 4. The ink ribbon cassette according to claims 1 to 3, wherein the rotating body is a gear. 5. The ink ribbon cassette according to claims 1 to 3, wherein the rotating body is a roll. 6. The ink ribbon cassette according to claim 1 or 2, wherein the spacer according to claim 2 or 3 is integrated with the lid of the case.
