Abstract: A print system includes a supporting base, and a ribbon shaft rotatably installed inside the supporting base for carrying a ribbon. The print system further includes a chip card connected to the ribbon shaft for storing information of the ribbon, and a card reader installed on a side of the supporting base for reading the information stored in the chip card as the ribbon shaft is installed inside the supporting base.

Abstract: A print system includes a paper feed device; a print device which has a platen roller and a print head and inserts the fed paper and an ink ribbon at a head position between the platen roller and the print head to perform printing; a disjunction device which relatively moves the platen roller with respect to the print head between a contact position where the platen roller contacts and a separation position where the platen roller is away therefrom; a non-print section acquiring device which acquires non-print section data of a character image in a feed direction of the paper from print data; and a print control device which controls the devices. The print control device relatively moves the platen roller to the separation position during a non-print section of the fed paper passes through the print head, based on the non-print section data.

Abstract: A driving apparatus includes a driving gear bidirectionally rotatable by a driving source, at least two driven gears selectively driven by the driving gear, at least two swing gears connected to the driving gear to operate in combination with the driving gear and to transmit a driving force of the driving gear to the driven gears, a swing lever pivotally disposed to support the swing gears, and an adjusting unit to adjust a swing position of the swing lever.
