IMAGE FORMING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240103422 titled 'IMAGE FORMING APPARATUS

Simplified Explanation

The image forming apparatus described in the patent application includes a drive source, a rotary member, a first coupling movable in an axial direction, and a unit with a second coupling to receive the driving force from the first coupling.

• The apparatus body contains the drive source, rotary member, and first coupling.
• The unit is attachable to and detachable from the apparatus body and includes the second coupling.
• The rotary member has an abutting portion.
• The first coupling has an abutted portion to engage with the abutting portion.
• A first urging member in the apparatus body urges the first coupling in a direction opposite to the rotation direction.

1. 1. 1. Possible Prior Art

There may be prior art related to coupling mechanisms in image forming devices, but specific examples are not provided in the patent application.

1. 1. 1. Unanswered Questions
         1. How does the first coupling ensure a secure connection with the rotary member during operation?

The patent application does not detail the specific mechanisms that ensure the first coupling remains engaged with the rotary member under varying conditions.

1. 1. 1. 1. What materials are used in the construction of the first and second couplings to withstand the forces involved in image forming processes?

The patent application does not specify the materials used in the construction of the couplings, which could impact the durability and longevity of the apparatus.

Original Abstract Submitted

an image forming apparatus includes an apparatus body including a drive source, a rotary member, and a first coupling movable in an axial direction with respect to the rotary member, and a unit attachable to and detachable from the apparatus body, the unit including a second coupling configured to receive the driving force by engaging with the first coupling. the rotary member includes an abutting portion. the first coupling includes an abutted portion configured to be abutted with the abutting portion, and is configured to rotate in the first rotation direction together with the rotary member in a case where the abutting portion presses the abutted portion. the apparatus body further includes a first urging member configured to urge the first coupling in a second rotation direction opposite to the first rotation direction.
