Abstract
Abstract The present invention provides a preset counter apparatus for a copying machine wherein input keys are capable of independently controlling the numerical value of the number of copies to be made and displayed. Thus, an operator can activate one key to change the digit positions of units and another key to change the digit position of tens. The control of the number of copies to be made is specifically designed to facilitate operator use and to avoid operator errors. Simultaneous activation of more than one key prevents any change in any values in both the units and tens positions.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
130 words
A preset counter apparatus for copying machines and the like comprising: display means for displaying numerical values at least in the digit positions of units and tens; a first input key provided in a corresponding relation to the digit position of units for generating a signal when operated; a second input key provided in a corresponding relation to the digit position of tens for generating a signal when operated; display control means, responsive to said signals generated by the first and second keys, for varying the numerical values of each digit position of units and tens stepwise respectively; and control means for setting "0" in the digit position of units when generating said signal of said second input key regardless of said value displayed in said digit position of units.
Claim 2
Dependent Claim
130 words
A preset counter apparatus for copying machines and the like comprising: display means for displaying numerical values at least in the digit positions of units and tens; a first input key provided in a corresponding relation to the digit position of units for generating a signal when operated; a second input key provided in a corresponding relation to the digit position of tens for generating a signal when operated; display control means, responsive to said signals generated by the first and second keys, for varying the numerical values of each digit position of units and tens stepwise respectively; and control means for setting "0" in the digit position of units when generating said signal of said second input key regardless of said value displayed in said digit position of units.
Claim 3
Dependent Claim
30 words
The invention of claim 1 further including a timer means for automatically incrementing a digit position after a predetermined time period during a continual activation of an first input key.
Claim 4
Dependent Claim
29 words
The invention of claim 1 further including a reset key means for setting the numerical values of units to one and numerical values of tens to zero when depressed.
Claim 5
Dependent Claim
35 words
The invention of claim 1 further including a setting means for automatically setting the numerical values of units to one and numerical values of tens to zero when electric power is supplied to the machine.
