Image Forming Apparatus Groove Integration for Sub Scanning Downsizing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing configuration of image forming apparatuses with separate guides for drum cartridges and exposure heads in the sub scanning direction hinders the miniaturization of the apparatus in this direction.
Innovation Solution
The image forming apparatus integrates a groove system that guides both the installation of drum cartridges and the positioning of exposure heads in the sub scanning direction, allowing for a unified approach to reduce the overall size by eliminating the need for separate guides and positioning mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate guides for drum cartridges and exposure heads are provided in the sub scanning direction, then the positioning accuracy and installation guidance are improved, but the apparatus size in the sub scanning direction increases
Solution Approach 1:
The patent combines the drum cartridge guide function and exposure head positioning function into a single integrated groove structure. The groove is configured to simultaneously receive and guide the drum cartridge during installation while also serving as the positioning reference for the exposure head in the sub scanning direction, thereby eliminating the need for separate guiding components and reducing the overall apparatus size.
Solution Approach 2:
The groove structure performs multiple functions: it guides the drum cartridge installation, positions the exposure head in the sub scanning direction, and provides a reference for alignment between the exposure head and photoconductor drum. This multi-functional design replaces what would traditionally require separate dedicated components for each function.
2Ease of operation
If separate guides for drum cartridges and exposure heads are provided in the sub scanning direction, then the installation guidance and positioning are improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple guiding and positioning functions into a single groove structure, reducing the number of separate components. The groove is designed with specific geometric features that provide installation guidance for drum cartridges while simultaneously serving as the positioning reference for exposure heads, thereby simplifying the overall device structure.
Solution Approach 2:
The integrated groove serves as a universal component that performs multiple functions: guiding drum cartridge installation, positioning exposure heads, and providing alignment references. This multi-functionality eliminates the need for separate dedicated guides and positioning mechanisms, reducing device complexity.

AI summary
An image forming apparatus is disclosed which includes a housing, one or more drum cartridges, and one or more exposure heads. Each of the one or more drum cartridges includes a photoconductor drum and is installable in the housing. Each of the one or more exposure heads is configured to expose a corresponding photoconductor drum to light, and to be movable between an exposure position fit to expose the corresponding photoconductor drum to light and a retreated position away from the corresponding photoconductor drum. The housing has a groove through which to guide installation of the drum cartridge and in which to cause an exposure head in a corresponding exposure position to be located in place in a sub scanning direction.
