SHEET CONVEYANCE APPARATUS AND IMAGE FORMING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240199354 titled 'SHEET CONVEYANCE APPARATUS AND IMAGE FORMING APPARATUS

The patent application describes a sheet conveyance apparatus with a unique ratchet mechanism for efficient transmission of drive force.

The apparatus includes a conveyance member, a drive source, a first member with a first ratchet portion, a second member with a second ratchet portion, and an urging portion.
The first ratchet portion has multiple transmission surfaces and a guide surface, while the second ratchet portion also has multiple transmission surfaces and a guide surface.
One of the first member and the second member can move axially between engaged and separated positions.
The number of times the members can move from separated to engaged positions while the second member rotates once with respect to the first member is limited.
This design ensures smooth drive transmission without excessive movement between the members.

Potential Applications: - Printing machines - Packaging equipment - Conveyor systems

Problems Solved: - Efficient drive transmission - Reduced wear and tear on components - Precise sheet conveyance

Benefits: - Improved reliability - Enhanced performance - Cost-effective operation

Commercial Applications: Title: Innovative Sheet Conveyance Apparatus for Enhanced Drive Transmission This technology can be utilized in various industries such as printing, packaging, and manufacturing for efficient sheet conveyance and drive transmission.

Questions about Sheet Conveyance Apparatus: 1. How does the ratchet mechanism in the apparatus improve drive transmission efficiency? The ratchet mechanism in the apparatus ensures smooth and precise drive transmission by limiting the movement between the members during rotation.

2. What are the potential benefits of using this sheet conveyance apparatus in printing machines? Using this apparatus in printing machines can lead to improved reliability, reduced maintenance costs, and enhanced overall performance.

Original Abstract Submitted

a sheet conveyance apparatus includes a conveyance member, a drive source, a first member including a first ratchet portion, a second member including a second ratchet portion, and an urging portion. the first ratchet portion has a plurality of first transmission surfaces and a first guide surface. the second ratchet portion has a plurality of second transmission surfaces and a second guide surface. one of the first member and the second member is movable in the axial direction between an engaged position and a separated position. the number of times the holding surface allows the one of the first member and the second member to move from the separated position to the engaged position while the second member rotates once in the rotational direction with respect to the first member is smaller than the number of contact positions included in the plurality of contact positions during the drive transmission period.
