Abstract
Abstract A numeral setting apparatus for setting numerals such as copy magnification, copy density, or the like includes an operating member such as up/down keys or a volume lever and a setting device to set numerals corresponding to a magnitude of force which is applied to the operating member. When a larger force is applied to the operating member, the setting device changes the numerals in larger increments than those in the case where a smaller force is applied.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
63 words
A numeral changing apparatus, comprising: an operating member; and changing means for changing numerals in first predetermined numerical increments of one-by-one when a magnitude of force applied to said operating member is within a predetermined range, and changing the numerals in second predetermined numerical increments larger than the first predetermined numerical increments when the magnitude of force is larger than the predetermined range.
Claim 2
Dependent Claim
63 words
A numeral changing apparatus, comprising: an operating member; and changing means for changing numerals in first predetermined numerical increments of one-by-one when a magnitude of force applied to said operating member is within a predetermined range, and changing the numerals in second predetermined numerical increments larger than the first predetermined numerical increments when the magnitude of force is larger than the predetermined range.
Claim 3
Dependent Claim
53 words
An apparatus according to claim 1, wherein said changing means changes the numerals by first predetermined increments of "1" when the magnitude of the force is within the predetermined range, and changes the numerals by second predetermined increments greater than "1" when the magnitude of the force is larger than the predetermined range.
Claim 4
Dependent Claim
72 words
An apparatus according to claim 1, further comprising a plurality of contacts, wherein a contact to be closed in the case when the magnitude of force within the predetermined range is applied is different from a contact to be closed when the magnitude of force larger than the predetermined range is applied, and said changing means changes the predetermined increments in accordance with the closed state of the plurality of said contacts.
Claim 5
Dependent Claim
32 words
An apparatus according to claim 1, wherein said changing means changes the numerals in first predetermined increments even if the magnitude of the force has any value included in the predetermined range.
Claim 6
Dependent Claim
66 words
An image forming apparatus, comprising: an operating member; and changing means for changing numerals regarding image formation in first predetermined numerical increments of one-by-one when a magnitude of force applied to said operating member is within a predetermined range, and changing the numerals in second predetermined numerical increments larger than the first predetermined numerical increments when the magnitude of force is larger than the predetermined range.
Claim 7
Dependent Claim
66 words
An image forming apparatus, comprising: an operating member; and changing means for changing numerals regarding image formation in first predetermined numerical increments of one-by-one when a magnitude of force applied to said operating member is within a predetermined range, and changing the numerals in second predetermined numerical increments larger than the first predetermined numerical increments when the magnitude of force is larger than the predetermined range.
Claim 8
Dependent Claim
53 words
An apparatus according to claim 5, wherein said changing means changes the numerals by first predetermined increments of "1" when the magnitude of the force is within the predetermined range, and changes the numerals by second predetermined increments greater than "1" when the magnitude of the force is larger than the predetermined range.
Claim 9
Dependent Claim
32 words
An apparatus according to claim 5, wherein said changing means changes the numerals in first predetermined increments even if the magnitude of the force has any value included in the predetermined range.
Claim 10
Dependent Claim
89 words
An image forming apparatus, comprising: an operating member; first and second contacts which are closed to correspond to first and second magnitudes of displacement increments of said operating member; and setting means for setting numerals regarding image formation corresponding to whether said first and second contacts are closed, wherein said setting means changes numerals in first predetermined numerical increments of one-by-one when said first contact is closed, and changes the numerals in second predetermined numerical increments larger than the first predetermined numerical increments when said second contact is closed.
Claim 11
Dependent Claim
89 words
An image forming apparatus, comprising: an operating member; first and second contacts which are closed to correspond to first and second magnitudes of displacement increments of said operating member; and setting means for setting numerals regarding image formation corresponding to whether said first and second contacts are closed, wherein said setting means changes numerals in first predetermined numerical increments of one-by-one when said first contact is closed, and changes the numerals in second predetermined numerical increments larger than the first predetermined numerical increments when said second contact is closed.
Claim 12
Dependent Claim
64 words
An apparatus according to claim 8, wherein said setting means changes the numerals in accordance with first predetermined increments when said first contact is closed, and changes the numerals in second predetermined increments larger than the first predetermined increments when said first and second contacts are closed, wherein the first predetermined increment includes a minimum changing quantity which is changeable by said operating member.
Claim 13
Dependent Claim
35 words
An apparatus according to claim 8, wherein a first magnitude of the displacement closes said first contact, and said first magnitude is smaller than a second magnitude of the displacement for closing said second contact.
Claim 14
Dependent Claim
48 words
An apparatus according to claim 8, wherein said setting means changes the numerals by first predetermined increments of "1" when said first contact is closed, and changes the numerals by second predetermined increments greater than "1" when said first contact is closed and said second contact is closed.
Claim 15
Dependent Claim
66 words
A numeral changing apparatus, comprising: an operating member for changing numerals having a plurality of values; and changing means for changing the numerals by first predetermined increments of "1" when a magnitude of force applied to said operating member is within a predetermined range, and changing the numerals in second predetermined increments greater than "1" when the magnitude of force is larger than the predetermined range.
Claim 16
Dependent Claim
66 words
A numeral changing apparatus, comprising: an operating member for changing numerals having a plurality of values; and changing means for changing the numerals by first predetermined increments of "1" when a magnitude of force applied to said operating member is within a predetermined range, and changing the numerals in second predetermined increments greater than "1" when the magnitude of force is larger than the predetermined range.
Claim 17
Dependent Claim
72 words
An apparatus according to claim 12, further comprising a plurality of contacts, wherein a contact which is closed when the magnitude of force within the predetermined range is applied to said operating member is different from a contact which is closed when the magnitude of force larger than the predetermined range is applied, and said changing means changes the numerals in accordance with the closed state of the plurality of said contacts.
