CONSTITUTION:One end of a cassette lever spring 7 acting to a cassette lever 5 for fixing an ink ribbon cassette 2 is folded downwards of the ink ribbon cassette 2 so as to press up the ink ribbon cassette 2. In this construction, the ink ribbon cassette 2 is made stable before loading and, on the other hand, pressed up to be easily ejected before unloading. In this manner, the ink ribbon cassette can be pressed both in fixing and removing direction with one spring, which realizes a lower-cost device. |
