Image Reading Apparatus Two-Sided Mode Adjustment Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In two-sided simultaneous reading systems, the initial adjustment operation for the back side reading unit often starts only upon user instruction for two-sided reading, leading to increased waiting time before reading commences, reducing convenience due to prolonged adjustment times.
Innovation Solution
The image reading apparatus initiates the initial adjustment operation of the second reading unit when the two-sided reading mode is set, allowing for concurrent preparation and reducing the waiting time before actual reading begins.

Engineering Contradiction Analysis
1Use of energy by stationary object
If the initial adjustment operation of the back side reading unit starts only upon user instruction for two-sided reading, then power consumption is reduced and unit life is extended, but the waiting time before reading commences increases
Solution Approach 1:
The system performs the initial adjustment operation of the back side reading unit in advance when two-sided reading mode is selected, before the actual reading process begins. This preliminary action reduces the waiting time during the reading operation by preparing the back side reading unit beforehand, while still allowing the unit to remain inactive during one-sided reading to conserve power.
2Productivity
If the initial adjustment operation of the back side reading unit starts upon user instruction, then the reading unit is activated only when needed, but the time required from job start instruction to reading start increases
Solution Approach 1:
The system initiates the initial adjustment operation as a preliminary action when two-sided reading mode is selected, completing the adjustment process before the actual reading begins. This reduces the adjustment time during the reading operation itself, thereby improving overall reading efficiency while maintaining proper activation control of the reading unit.
