Solution Overview
Problem
Existing image forming apparatuses lack an intuitive method for counting and inputting numerical values in a GUI numerical value input field.
Innovation Solution
An image forming apparatus with a touch panel that detects multiple finger touches, calculates the angle change of one finger relative to another as a fulcrum, and uses this information to count and input numerical values through a gesture operation resembling dial rotation.

Engineering Contradiction Analysis
1Ease of operation
If conventional touch panel operations are used for numerical value input, then the device structure remains simple, but the operation becomes non-intuitive and time-consuming
Solution Approach 1:
The patent replaces conventional mechanical or button-based input methods with a touch panel gesture recognition system. The angle change calculating portion detects finger movements and calculates angular changes to determine numerical value increments, substituting physical interaction with intuitive gesture-based control that mimics natural dialing motions.
Solution Approach 2:
The system dynamically adjusts numerical value counting based on the speed and magnitude of finger angle changes. The numerical value counting portion responds to real-time gesture dynamics, where faster or larger angle changes result in quicker counting, allowing users to input values efficiently by varying their gesture intensity and speed.
2Ease of operation
If multiple finger touch detection is implemented, then numerical value input becomes more intuitive, but the device complexity increases
Solution Approach 1:
The touch panel serves multiple functions: it detects basic touches, identifies multiple fingers, calculates angle changes between fingers, and triggers numerical value counting. This multi-functionality consolidates what would otherwise require separate components into a single integrated touch interface, managing complexity through functional consolidation.
Solution Approach 2:
The angle change calculating portion acts as an intermediary between the touch panel's raw finger position data and the numerical value counting portion. It processes complex multi-finger gesture information into simplified angle change metrics that drive the counting function, mediating the complexity transformation from gesture detection to value input.
3Productivity
If angle change calculation is used for counting, then counting speed increases, but measurement precision requirements increase
Solution Approach 1:
The system continuously monitors finger angle changes and provides real-time feedback through numerical value updates. The angle change calculating portion tracks gesture progression and feeds this information back to the numerical value counting portion, allowing the system to maintain precision by continuously adjusting the count based on ongoing gesture measurement rather than relying on single-point measurements.

AI summary
To provide an image forming apparatus having an excellent operability for inputting a numerical value, an image forming apparatus (1) includes a touch panel (20), an angle change calculating portion (100), and a numerical value counting portion (130). The touch panel (20) is configured to detect touches of a plurality of fingers. The angle change calculating portion (100) is configured to, when it is detected that a first finger and a second finger have been touched to the touch panel (20), calculate an angle change of the second finger with the first finger as a fulcrum. The numerical value counting portion (130) is configured to count a numerical value that is input, in response to the angle change calculated by the angle change calculating portion (100).
