Operation Panel Mounting Layout for Serviceable Image Formers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face challenges in balancing user operability, miniaturization, and maintenance efficiency due to the arrangement of the operation unit, which interferes with sheet discharge and requires removal for maintenance, hindering space-saving designs and work efficiency.
Innovation Solution
The operation unit is mounted to a support frame via a fixing device that passes through a gap between the frame and support portion, allowing it to be removable without detaching the unit, and the control unit is accommodated below the operation unit, facilitating maintenance without removing the operation unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operation unit is arranged above the apparatus main body to improve user operability and enable space-saving design, then the apparatus can be miniaturized and the operation unit does not interfere with sheet discharge, but the operation unit blocks access to internal components for maintenance
Solution Approach 1:
The mounting structure is segmented into multiple components: the operation unit support portion, the fixing device, and the gap space. This segmentation allows the operation unit to be independently mounted and removed without affecting the entire apparatus structure, enabling easy maintenance access while preserving the space-saving design.
Solution Approach 2:
The gap between the frame and support portion acts as an intermediary space that accommodates the fixing device. This intermediary structure enables the operation unit to be securely mounted during normal operation while allowing easy removal for maintenance by accessing through the gap, thus resolving the contradiction between secure mounting and easy maintenance.
2Adaptability or versatility
If the operation unit is made larger to display more information and adapt to touch panels, then user interface capability is improved, but the apparatus size increases and interferes with sheet discharge path
Solution Approach 1:
The operation unit is positioned in the vertical dimension above the apparatus main body rather than extending horizontally. This dimensional change allows the operation unit to have sufficient display area and touch panel space without increasing the horizontal footprint of the apparatus, thus maintaining a compact size while providing enhanced user interface capabilities.
3Reliability
If the operation unit is fixed securely to the frame to ensure stability during operation, then operational reliability is improved, but the operation unit cannot be easily removed for maintenance
Solution Approach 1:
The fixing device provides dynamic mounting capability: during normal operation, the operation unit is securely fixed to ensure stability and reliability; during maintenance, the fixing device can be quickly released through the gap, allowing easy removal and reinstallation. This dynamic characteristic resolves the contradiction between secure fixing and easy removal.

AI summary
An image forming apparatus includes an apparatus main body configured to form an image on a sheet, an operation unit arranged above the apparatus main body in a vertical direction, a frame constituting the apparatus main body, a support portion configured to mount the operation unit to the frame, and a unit arranged within an area below the operation unit in the vertical direction, wherein the unit comprises a mounting portion configured to fix the unit to the frame, wherein the mounting portion is fixed to the frame by a fixing device in a state where the mounting portion passes through a gap formed between the frame and the support portion, and wherein the fixing device that fixes the mounting portion is removable in a state in which the operation unit is mounted to the frame via the support portion.
