Power supply circuit, image forming device, power panel and processing unit

Abstract

The invention provides a power panel with convenient assembly and disassembly, and further provides an image forming device not capable of generating poor connection among the power panel, an image carrier, a current-carrying device, a processing unit and the like. The method is characterized in that: a contact terminal (4) is arranged on a lateral surface of the processing unit (2); a contact terminal (92) on the body side is arranged at a position contacted with the contact terminal (4); the contact terminal (92) on the body side can be positioned in a displacing way along a direction vertical to a moving direction of the processing unit (2), and retreats in the direction vertical to the moving direction corresponding to the stress when moving from the processing unit (2) by attaching to the processing unit through a spring (93); and when the processing unit (2) is being mounted, the processing unit is connected with the contact terminal (4) on the processing unit side in a pressingway.

Description

technical field [0001] The present invention relates to power supply circuits for copiers, printers, facsimile machines, etc., image forming apparatuses, power boards, and processing units. In more detail, it relates to a processing unit or a power board that can be installed and detached from the image forming device, and is electrically connected to the image forming device body. Background technique [0002] In an image forming apparatus in which a detachable processing unit can be attached, when the processing unit is installed, necessary power is supplied from the main body to drive the processing unit. [0003] Therefore, in the image forming apparatus, a power supply board from which power is supplied to the processing unit is provided. [0004] The power supply board is usually detachably installed in the main body of the image forming apparatus, the power supply circuit from the power supply board to the processing unit is formed in the main body, and the circuit i...

Problems solved by technology

[0009] However, when the power supply circuit is formed by crimping such a leaf spring-shaped connecting member, accuracy in positional relationship between the processing unit 301, the power board 302, and the connecting member 304 is required. In addition, because the connecting member 304 is in the shape of a leaf spring, and the contact surface will be worn due to friction, which will also cause poor contact

[0010] Also, in this configuration, since the places where the processing unit 301, the power supply board 302, and the connecting member 304 are installed are limited, it also becomes a constraint on the mechanical design.
