Retractable Handle Discharge Tray for Compact Recording Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable recording apparatuses face challenges in size increase due to protruding handle sections and the need for additional components like display and operating sections, which complicate their design and usability.
Innovation Solution
A recording apparatus design featuring a discharge tray with a through section and handle section that can be accommodated within the casing, allowing for compact size and improved aesthetics, along with a scanner section that can operate in fixed or moving modes using acceleration sensors for image correction and posture detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a handle section is provided on a portable recording apparatus to enable easy carrying, then ease of operation is improved, but the size of the recording apparatus increases when the handle section protrudes from the paper feeding cassette
Solution Approach 1:
The handle section is designed to be movable between a protruding state for carrying and a retracted state for compact storage. The handle section can be lifted up and inserted into the paper feeding cassette, allowing it to dynamically change position based on whether the apparatus is being carried or stored, thus resolving the contradiction between ease of carrying and compact size.
2Adaptability or versatility
If a hand-held scanner is mounted on a recording apparatus to enhance functionality, then adaptability is improved, but the size of the recording apparatus increases due to additional display and operating sections
Solution Approach 1:
The discharge tray is designed to serve multiple functions: it acts as a paper discharge tray for the printer and simultaneously as a holding tray for the hand-held scanner. By making the discharge tray multi-functional, the patent avoids adding separate components for scanner support, thereby enhancing functionality without increasing the overall apparatus size.
3Ease of operation
If the discharge tray is designed with a through section and handle section positioned outside the casing for easy carrying, then ease of operation is improved, but dust may infiltrate through the opening when the discharge tray is in the retracted state
Solution Approach 1:
The handle section is extracted from the main body of the discharge tray and positioned separately at the rear end. This allows the handle section to be independently managed - protruding for carrying or retracted into the casing for protection - while the through section remains positioned to facilitate easy insertion and removal of the discharge tray without compromising dust protection.
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 design enables users to carry the apparatus in a compact form, suppresses size increase, prevents dust infiltration, and enhances image quality and user experience through mode detection and posture-based text orientation.
Implementation Method 1
an acceleration sensor that detects acceleration data in a case where the scanner section is separated from the printer section

AI summary
There is a problem in that, when a handle section is provided in a recording device, the handle section protrudes from a casing and the size of the recording apparatus is increased. A recording apparatus is provided with a recording head which records on paper and a discharge tray which is provided to be able to slide with regard to a casing and holds the paper which is recorded upon using the recording head and discharged, where the discharge tray has a through section which is formed on the downstream side in a discharge direction and a handle section which is formed at an edge section more to the downstream side in the discharge direction than the through section, the handle section is accommodated inside of the casing in a state where the discharge tray is accommodated in the casing, the through section and the handle section are positioned outside of the casing in a state where the discharge tray is drawn out from the casing, and the discharge tray is supported in a state of hanging down from the casing.
