Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bill processing apparatuses are costly and inefficient in performing authenticity judgments for both bills and bar-coded paper sheets, as they require multiple dedicated sensors, increasing component complexity and costs.
Innovation Solution
A bill processing apparatus equipped with a light emitting part, a light receiving part, and a light emission control part that determines whether the object is a bill or a bar-coded paper sheet based on received light, adjusting lighting intervals to optimize authenticity judgment, allowing for the use of a common sensor system for both types of objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dedicated sensors (magnetic sensor and optical sensors) are installed for reading bills and dedicated sensors are installed for reading bar-codes, then the authenticity judgment can be performed for both bills and bar-coded paper sheets, but the number of components increases and the device complexity increases
Solution Approach 1:
The patent applies universality by enabling a single optical sensor to perform multiple functions: reading both bills and bar-coded paper sheets. The determining part distinguishes between the two object types and the light emission control part adjusts the lighting interval accordingly, allowing one sensor system to replace what would traditionally require separate dedicated sensors for each object type.
Solution Approach 2:
The patent applies dynamics by making the lighting interval adjustable based on the detected object type. The light emission control part dynamically changes the lighting interval according to whether the object is a bill or a bar-coded paper sheet, optimizing the reading process for each type while using the same physical sensor infrastructure.
2Measurement precision
If multiple dedicated sensors are installed for reading bills and bar-codes, then the authenticity judgment accuracy is maintained, but the device complexity and cost increase
Solution Approach 1:
The patent applies universality by enabling a single optical sensor to perform multiple functions: reading both bills and bar-coded paper sheets. The determining part distinguishes between the two object types and the light emission control part adjusts the lighting interval accordingly, allowing one sensor system to replace what would traditionally require separate dedicated sensors for each object type.
Solution Approach 2:
The patent applies parameter changes by modifying the lighting interval parameter based on the detected object type. The light emission control part adjusts this temporal parameter to optimize the optical reading process for either bills or bar-coded paper sheets, maintaining measurement precision through parameter optimization rather than through hardware multiplication.

AI summary
A bill processing apparatus capable of inexpensively performing an authenticity judgment of a bill and a paper sheet on which a bar code is printed is provided. The bill processing apparatus has light emitting parts (80a, 81b) for irradiating an identification object passing through a traveling route with light; a light receiving part (81a) receiving light from the identification object that is irradiated by the light emitting parts (80a, 81b); a determining part (232) determining whether the identification object is a bill or a paper sheet on which a bar code is printed based on the light received by the light receiving part (81a); and a light emission control part controlling the light emission of the light emitting parts (80a, 81b). The light emission control part changes the lighting interval according to the object determined by the determining part (232).
