Light Emission Controller for Image Forming Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming devices do not visually express operator operations at the operating portion to the operator, lacking control over light emission patterns for operator interactions.
Innovation Solution
An image forming device with a light emission controller that manages multiple light emission patterns from various light sources, prioritizing delayed start timings for subsequent patterns to avoid overlap and emit specific patterns indicating operator actions and device operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple light emission patterns are emitted simultaneously to indicate operator operations and device operations, then visual information is provided, but light emission patterns overlap causing confusion
Solution Approach 1:
The light emission controller determines whether a light emission pattern is currently being emitted before emitting a new pattern. This preliminary check prevents overlapping light emission patterns that would cause confusion, ensuring clear visual information is provided to the operator about device operations and operator actions.
2Loss of information
If light emission patterns are delayed to avoid overlap, then visual clarity is improved, but response time to operator operations increases
Solution Approach 1:
The light emission controller dynamically adjusts the timing of light emission patterns based on the current state. When no pattern is currently emitting, the controller emits the pattern immediately without delay. When a pattern is already emitting, the controller waits until it completes before emitting the next pattern. This dynamic timing optimization ensures both visual clarity and minimal response time.

AI summary
An image forming device includes a light emission controller that controls emission of a plurality of types of light emission patterns from a plurality of light sources. The light emission controller emits respective light emission patterns corresponding to the operation. When among the plurality of types of light emission patterns, the preceding light emission pattern overlaps with the subsequent light emission pattern, the light emission controller preferentially emits the subsequent light emission pattern having a delay in the light emission start timing. The light emission controller also emits respective first light emission patterns corresponding to the operation, and emits the second light emission pattern expressing the predetermined operation. When any type of emission of the first light emission pattern among the plurality of types of first light emission patterns overlaps with emission of the second light emission pattern, the light emission controller preferentially emits the second light emission pattern.
