    摘要： There is provided a printer comprises a first type group having a first font; a second type group having a second font; a first read only memory in which a space traveling amount corresponding to each type of the first type group has been stored; a second read only memory in which a space traveling amount corresponding to each type of the second type group has been stored; and a microprocessor which selects the 1st read only memory when the 1st type group is used, thereby allowing the propotional spacing operation corresponding to each type of the 1st type group to be performed, and which selects the 2nd read only memory when the 2nd type group is used, thereby allowing the proportional spacing operation corresponding to each type of the 2nd type group to be performed. Since the invention can be constituted by a simple hardware, by merely adding this hardware to a conventional printer such as an electronic typewriter, the fine proportional spacing can be executed for each type of various kinds of fonts.

    摘要： An impact printer is provided which is capable of printing at either 10 characters per inch (standard pitch) or 15 characters per inch (compressed pitch) by changing the type character carrying member, such type carring member including multiple font character sets thereon. The type character carrying members or bands include timing marks thereon for detecting or sensing the type band (standard or compressed pitch), the type character font set, and for tracking the type characters on the band. The printer also includes time shared hammer means which are movable or shifted a precise distance of 1/10 inch for a standard pitch band or a precise distance of 1/15 inch for a compressed pitch band, such movement being operable by control mechanism responsive to pulses derived from the timing marks relative to the horizontal position mechanism and the type band on the printer (standard or compressed pitch).
