Card Cassette Shutter Fixing Mechanism for Secure Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing card cassette devices lack sufficient security measures to prevent unauthorized access and card loss, especially when not mounted on the main unit, and do not ensure a one-to-one correspondence with the main unit, leading to potential theft and inadequate security.
Innovation Solution
A card cassette device with a shutter fixing mechanism that secures the card outlet in a closed state when not mounted and an open state locking mechanism that allows the card outlet to be opened and locked only when mounted, using a solenoid and lock mechanism, ensuring secure operation and conformity verification with the main unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the card cassette device is made detachable for easy loading and adding of cards, then the ease of operation is improved, but the security against loss and theft of cards deteriorates
Solution Approach 1:
The shutter is preliminarily set to automatically close when the cassette device is detached from the main unit, preventing card loss before the detachment operation is completed. This preliminary security measure ensures that even if cards are present in the outlet, they cannot be stolen during the loading/adding process.
Solution Approach 2:
The shutter acts as an intermediary mechanism between the card outlet and the external environment. It mediates the security requirement by physically blocking access to cards during detachable operations, allowing the device to maintain both ease of operation and security through this intermediate protective element.
2Reliability
If a conventional locking mechanism is used to secure the card outlet, then the security is improved, but the device complexity increases
Solution Approach 1:
The shutter mechanism serves itself by automatically closing when the cassette device is detached, without requiring separate locking operations or complex lock structures. The detachment action itself triggers the security measure, eliminating the need for additional locking components and reducing overall device complexity.
Solution Approach 2:
The shutter performs multiple functions: it controls card dispensing during normal operation and simultaneously provides security locking when the device is detached. This multi-functionality eliminates the need for separate locking mechanisms, reducing device complexity while maintaining security.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents unauthorized access and ensures secure operation by maintaining the card outlet in a closed state unless properly mounted, enhancing security and ensuring only authorized devices can be used, thus achieving a higher security level with a simple structure.
Implementation Method 1
a stopper member moving device for moving the stopper member and/or the stopper member engaging hole to perform engagement or disengagement of the stopper member with/from the stopper member engaging hole

AI summary
A card cassette device of a card dispensing apparatus ensures elimination of measures for illegally opening a card outlet from the outside in a non-mounted state and makes it possible to open the card outlet according to the necessity in a mounted state, raising security level. A movable shutter for opening and closing a card outlet has a stopper member engaging hole and a lock member engaging hole. A stopper member is engaged with the stopper member engaging hole by a stopper member moving device, thereby fixing the shutter in its closed state in the non-mounted state. A lock member is engaged with the lock member engaging hole by a lock member moving device, thereby canceling the closed state of the shutter and locking the shutter in its open state in the mounted state.
