Sheet-feeding apparatus with selectable unit feed and coefficient therefor

Claim 1

A print apparatus comprising: inputting mean for inputting data of characters and symbols to be printed, a printing mechanism for printing data inputted by said inputting mean on a printing medium, a feeding mechanism for relatively moving a printing head of said printing mechanism and said printing medium, unit feed amount selecting means for selecting a unit amount of feed of said relative movement, feed amount setting means for selecting coefficient to multiply said unit amount of feed selected by said unit feed amount selecting means and for setting an actual amount of feed, and said feed amount setting means including a coefficient select key for selecting said coefficient and displaying means for displaying said selected unit amount of feed and said selected coefficient to multiply said selected unit amount of feed, said displaying means having a number of display lamps less than the total number of coefficients, and said display means displays some of the coefficients by lighting plural display lamps simultaneously and some of the coefficients by lighting only one display lamp at a time in accordance with said coefficient selected by said coefficient select key, and controlling means for controlling said feed mechanism so that the amount of feed of said relative movement is said set actual amount of feed based on an output from said feed amount setting means.
