Abstract
Abstract There is an output apparatus which prints and outputs onto an ink ribbon in an electronic typewriter or the like. This output apparatus comprises: an output head to output a desired character through an ink ribbon; a cassette in which the ink ribbon is enclosed; a guide device to move the ink ` ribbon pulled out of the cassette in the direction having an angle of inclination with respect to the vertical direction; and a control unit to control the ink ribbon feed mechanism so as to stop the advance of the ink ribbon such that the length of ink ribbon pulled out of the cassette is made almost constant before and after the movement of the ink ribbon by the guide device. One motor is commonly used for print paper feed, ribbon feed, and ribbon lift up/down operations. The type wheel having a plurality of type elements is bilaterally rotated and its rotation amount is properly controlled to detect the home position of the wheel. The ribbon feed mechanism is controlled by the heteromorphic or noncircular rotary cam having grooves of different kinds of radii. The ink ribbon feed operation and the correction ribbon feed and lift up/down operations are also performed by the rotary cam. With this apparatus, the ink and correction ribbons can be efficiently used and the operation timing of the carriage can be accurately controlled.
