Abstract

In copying machines, traditional key/dial input for copy select coupled with numeric display have provided individual 0 thru 9 digit input for establishing the desired number of copies to be made. A system is provided for selecting a desired number of copies within the capabilities of the machine maintaining the features of existing keyboard/display systems and accomplishing this function in a minimum of space and at low manufacturing cost.

In copying machines, traditional key/dial input for copy select coupled with numeric display have provided individual 0 thru 9 digit input for establishing the desired number of copies to be made.

A system is provided for selecting a desired number of copies within the capabilities of the machine maintaining the features of existing keyboard/display systems and accomplishing this function in a minimum of space and at low manufacturing cost.

With reference to the figure, there is shown a control panel and graphics for a copier. The panel consists of four switches, a two digit display, two LED copy contrast indicators and graphic information for the operator.

The Start switch is used to initiate the machine's processing or copying cycle. When pressed, the machine will start up, process the number of copies selected and shut down.

MINIMUM SWTICH COPY SELECT SYSTEM

~ The Copy Contrast switch is used by the operator to select whether normal, lighter or darker copies are desired. Each momentary pressing of the switch changes the contrast feature from what it presently is to the next level in the sequence. Light emitting diodes (LEDs) are used to indicate whether darker or lighter contrast has been selected. The absence of both these indicating devices implies that normal copy contrast is available. Assuming that normal contrast is in use, both LEDs are off. hilomentarily pressing the Copy Contrast switch, the contrast feature changes to lighter copies and the Lighter LED is illuminated. Pressing the Copy Contrast switch again, the contrast feature changes to darker copies, the Lighter LED is turned off and the Darker LED is turned on. Again, momentarily pressing the Copy Contrast switch the contrast features return to normal copies and the Darker LED is turned off. This cycle of contrast selection will repeat as the momentary actuation of the contrast switch continues.

The unique part of the control console is the manner in which the number of copies are selected. Two switches, a count increment switch (shown in Figure 1 with the # symbol in its center) and the clear switch (shown with the letter C in its center) are used to generate the desired number of copies. The two digit segmented display is used to display the number of copies to the operator. In a machine standby condition, the number 1 is shown in the display.

In the standby or non-processing mode, the count increment switch is used to select the desired number of copies. If the switch (/I) is depressed and held depressed, the display will automatically count up a predeterimed rate. When the number of copies desired is reached and shown in the display, the switch is released and the display holds the desired...
