Abstract: PURPOSE:To enable easy replacement of a ribbon cassette and correction tape bobbins, by detecting the opened or closed state of a cover, moving a carriage to a central part of a moving range thereof when the cover is opened, and returning the carriage to an original position when the cover is closed. CONSTITUTION:When the run-out of an ink ribbon or a correction tape is detected, printing or correction is stopped. With a cover 29 opened, the condition is detected by a sensor 27, and the value in a current position counter 52 indicating the position of a carriage 23 is written into a memory 51c by a reading and writing means 50. The means 50 reads the coordinates of a central position and the current carriage position from a memory 51 and the memory 51c, and inputs the coordinates into a calculating means 53. The means 53 calculates the difference between the two coordinates, and sets the difference into a moving counter 54. The counter 54 sends pulses to a driver 55 until the value thus set becomes 0, and the driver 55 moves the carriage 23 to the center of a moving range of the carriage. Accordingly, a ribbon cassette 19 and tape bobbins 21 can be easily replaced.
