Printer with rotatable print band

A printer, comprising:

• a rotatable base having a circumferential surface with a plurality of holes therethrough;
• a flexible type belt having a front surface and a back surface, said back surface having a plurality of projections thereon each positioned to engage an associated on of said plurality of holes, said front surface having a plurality of types each corresponding to a different one of said plurality of projections;
• hammer means movably arranged within said base for assuming a first printing position and a second printing position to press selectively any of said plurality of projections and thereby selectively project said types corresponding thereto in one of a respective first projection direction, wherein printing can be performed on a first recording medium carried by a carrying means detachably mounted to the printer, and a second projection direction, wherein printing can be performed on a second recording medium separate from the printer;
• a counter for counting in accordance with the rotation of said base, each count by said counter indicating a type position;
• a disc mounted for rotation with said base, said disc including means for generating a first home position signal when said base occupies a first home position thereof and a second home position signal when said base occupies a second home position thereof, said home positions of said base being associated with said respective printing positions of said hammer means;
• detection means for detecting said home position signals;
• indicating means for providing an indication signal causing said hammer means to assume said first printing position when the carrying means is mounted to the printer and causing said hammer means to assume said second printing position when the carrying means is removed from the printer;
• key means for manually providing a selection signal causing said hammer means to assume said second printing position when the carrying means is mounted to the printer;
• and
• control means for controlling said counter to reset the count thereof in response to a home position signal output by said detection means selectively provided in response to the selection signal and indication signal.
