IMAGE READING DEVICE AND CONTROL METHOD FOR IMAGE READING DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240113641 titled 'IMAGE READING DEVICE AND CONTROL METHOD FOR IMAGE READING DEVICE
Simplified Explanation
The patent application describes an image reading device that includes a DC motor, a roller driven by the DC motor, a reading unit to read images from documents conveyed by the roller, and a control unit to manage the DC motor's driving. The control unit is designed to detect the power load value of the DC motor and determine if it exceeds a certain threshold value while controlling the motor to convey documents at different velocities.
- DC motor-driven image reading device:
- Includes a DC motor and a roller for document conveyance. - Reading unit to scan images from documents. - Control unit to manage DC motor driving.
- Control unit functionality:
- Detects power load value of DC motor. - Determines if load value exceeds threshold. - Adjusts conveyance velocity based on load value.
Potential Applications

Unanswered Questions
How does the control unit adjust the conveyance velocity based on the power load value of the DC motor?
The patent application does not provide specific details on the mechanism by which the control unit modifies the conveyance velocity. Further information on the algorithm or process involved would be beneficial.
What are the specific threshold values used by the control unit to determine power load conditions of the DC motor?
The abstract mentions a first threshold value, but it does not specify the exact numerical values used for this threshold or any subsequent thresholds. Understanding these values would provide insight into the device's operational parameters.
Original Abstract Submitted
an image reading device includes a dc motor, a roller driven by the dc motor, a reading unit configured to read an image from a document conveyed by the roller, and a control unit configured to control driving of the dc motor. the control unit is configured to detect a power load value of the dc motor. the control unit is configured to determine that the power load value of the dc motor exceeds a first threshold value in a state in which the control unit controls the dc motor to convey the document at a first conveyance velocity, and then, control the dc motor to convey the document at a second conveyance velocity lower than the first conveyance velocity.
