Banknote Feeder Motor Nesting in Winding Roller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing banknote storing/feeding devices face challenges in increasing storage capacity while maintaining a compact design, particularly when motor installation is restricted or desired within the device.
Innovation Solution
A paper sheet storing/feeding device with a motor partially housed inside the winding roller, utilizing a dual drive axis system to rotate the winding roller and reel, allowing for efficient winding and unwinding of tapes without the need for multiple motors, thus enhancing storage capacity without increasing device size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the motor is installed outside the device, then the device can be made compact as a whole, but it becomes difficult to install the motor outside the device when there is no place for installing it outside
Solution Approach 1:
The motor main body is disposed inside the winding roller, with the first drive axis projecting from one end and the second drive axis projecting from the other end. This nesting arrangement allows the motor to be housed within the existing structure of the winding roller, eliminating the need for external motor installation while maintaining compact device dimensions.
2Volume of moving object
If drum devices are applied one each to the winding roller and the reel, then the device can be made compact as a whole, but the number of motors increases and results in high cost
Solution Approach 1:
A single motor with dual drive axes serves multiple functions: the first drive axis rotates the winding roller while the second drive axis rotates the reel. This multi-functional design eliminates the need for separate motors for each component, reducing the total number of motors while maintaining compact device dimensions.
3Volume of moving object
If a single motor with dual drive axes is used, then the device remains compact, but the motor main body must be disposed inside the winding roller which increases structural complexity
Solution Approach 1:
The motor is divided into distinct functional components: the motor main body disposed inside the winding roller, the first drive axis projecting for winding roller rotation, and the second drive axis projecting for reel rotation. This segmentation allows each component to perform its specific function efficiently while maintaining overall structural compactness.

AI summary
The present invention provides a banknote storing/feeding device 23 that can increase a storing amount of banknotes while the device is made compact as a whole.The banknote storing/feeding device includes a winding roller 38 that winds and unwinds banknotes together with a tape 37, and a reel 40 that winds and unwinds the tape 37 with respect to the winding roller 38. The banknote storing/feeding device includes a motor 55 including a motor main body 56 disposed inside the winding roller 38, and a first drive axis 58 and a second drive axis 59 projecting from a first end portion side and a second end portion side of the motor main body 56. The banknote storing/feeding device includes a transmission mechanism 70 that transmits a drive force from the second drive axis 59 of the motor 55 to the reel 40. A drive force from the first drive axis 58 of the motor 55 is transmitted to the winding roller 38 to rotate the winding roller 38. A drive force of the second drive axis 59 of the motor 55 is transmitted to the reel 40 to rotate the reel 40.
