Displaceable Guide Member for Image Reading Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image reading apparatuses face issues with unsatisfactory setting properties when inserting media due to excessive space from the insertion port, leading to user burden and increased apparatus size.
Innovation Solution
An image reading apparatus with a displaceable medium placement portion and a guide member that adjusts between two inclination angles, guiding the medium during insertion and accommodation, reducing user burden and apparatus size by optimizing the guide member's position in association with the placement portion's movement.

Engineering Contradiction Analysis
1Ease of operation
If the space from the insertion port into the apparatus is made large to accommodate the medium placement portion, then the medium can be inserted and placed, but the setting property of medium insertion becomes unsatisfactory and the apparatus size increases
Solution Approach 1:
The guide member is configured to be displaceable between a first position and a second position. At the first position, the contact surface forms a first inclination angle with the placement surface to guide medium insertion. At the second position, the contact surface forms a second inclination angle with the placement surface. This dynamic adjustment allows the guide member to adapt to different operational states, improving medium insertion settings without requiring excessive fixed space in the apparatus.
Solution Approach 2:
The inclination angle of the contact surface relative to the placement surface is changed between two states. The first inclination angle is formed when the guide member is at the first position, and the second inclination angle is formed when the guide member is at the second position. By changing this geometric parameter, the guide member can effectively guide medium insertion while accommodating the medium placement portion, thereby improving setting property without increasing apparatus size.
2Ease of operation
If the guide member is positioned to guide medium insertion effectively, then setting property improves, but the space required in the apparatus increases
Solution Approach 1:
The guide member is configured to be displaceable between a first position and a second position. At the first position, the contact surface forms a first inclination angle with the placement surface to guide medium insertion. At the second position, the contact surface forms a second inclination angle with the placement surface. This dynamic adjustment allows the guide member to adapt to different operational states, improving medium insertion settings without requiring excessive fixed space in the apparatus.
Solution Approach 2:
The guide member can be accommodated within the insertion port when not in use, and extended when needed for guiding medium insertion. This nesting approach allows the guide member to provide its guiding function effectively while minimizing the space it occupies within the apparatus, thereby improving setting property without increasing the overall apparatus footprint.

AI summary
An image reading apparatus includes a guide member that guides a medium by bringing the medium into contact with a contact surface of a medium placement portion is displaceable between a first position at which the contact surface forms a first inclination angle with respect to a placement surface when viewed in a width direction and a second position at which the contact surface forms a second inclination angle with respect to the placement surface when viewed in the width direction, the guide member moves from a first position to a second position as the medium placement portion moves from an opening position to an accommodation position, and moves from the second position to the first position as the medium placement portion moves from the accommodation position to the opening position.
