Rotatable Housing Touch Panel Disable Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In processing terminals with rotatable housings, unintended operations can occur due to accidental touching of the touch panel when the user grips the second housing to rotate it, leading to potential misoperations and increased power consumption.
Innovation Solution
Incorporating an opening and closing sensor and a controller that detect the position of the second housing relative to the first housing, disabling the operation panel when the second housing is in the open position to prevent unintended operations and optimizing power usage.

1Ease of operation
If the touch panel is enabled during rotation operation, then the user can operate the terminal, but unintended operations occur due to accidental touching
Solution Approach 1:
The touch panel's operational state is dynamically adjusted based on the rotation angle of the second housing. The controller disables the touch panel when the rotation angle is within a predetermined range (indicating rotation operation), and enables it when the angle exceeds this range (indicating stable positioning). This dynamic state change prevents unintended operations during rotation while maintaining usability when stable.
2Duration of action of stationary object
If the touch panel remains enabled during rotation, then the display can be updated, but power consumption increases
Solution Approach 1:
The controller periodically monitors the rotation angle of the second housing and adjusts the touch panel state accordingly. When the rotation angle is within the predetermined range, the touch panel is disabled to save power. When the angle exceeds the range, the touch panel is enabled to allow user interaction. This periodic state adjustment optimizes power consumption while ensuring the display remains operational when needed.

AI summary
A processing terminal includes a first housing having an opening, a second housing, an operation panel disposed on the second housing. The second housing is rotatably attached to the first housing between a closed position in which the second housing closes the opening of the first housing and a non-closed position in which a gap is formed between the opening of the first housing and the second housing. The processing terminal further includes a sensor and a controller. The sensor is configured to detect at least one of the second housing in the closed position and the second housing in the non-closed position. The controller is configured to determine whether or not the second housing is in the non-closed position based on a detection result of the sensor and disable the operation panel upon determining that the second housing is in the non-closed position.
