A circuit board for an image forming apparatuses to which a first integrated circuit or a second integrated circuit is provided, comprising:
- an electric part provided to a first surface of the circuit board;
- a first attachment part provided to the first surface, to which at least one terminal of the first integrated circuit is attachable;
- a first conductor pattern formed on the first surface and configured to constitute at least a portion of a first wiring which connects the first attachment part and the electric part;
- a second attachment part provided to a second surface opposite to the first surface of the circuit board, to which at least one terminal of the second integrated circuit is attachable;
- a second conductor pattern formed on the second surface and configured to constitute at least a first portion of a second wiring which connects the second attachment part and the electric part;
- and
- a connecting via penetrating through the circuit board, extending from the first conductor pattern to the second conductor pattern, and configured to constitute a second portion of the second wiring.
An image forming apparatus comprising;
- a voltage conversion unit, having a circuit board to which a first integrated circuit or a second integrated circuit is provided, configured to convert a value of a voltage input to the circuit board;
- and,
- a control unit configured to control the image forming apparatus based on the voltage converted by the voltage conversion unit,
- wherein the circuit board comprises:
- an electric part provided to a first surface of the circuit board;
- a first attachment part provided to the first surface, to which at least one terminal of the first integrated circuit is attachable;
- a first conductor pattern formed on the first surface and configured to constitute at least a portion of a first wiring which connects the first attachment part and the electric part;
- a second attachment part provided to a second surface opposite to the first surface of the circuit board, to which at least one terminal of the second integrated circuit is attachable;
- a second conductor pattern formed on the second surface and configured to constitute at least a first portion of a second wiring which connects the second attachment part and the electric part;
- and
- a connecting via configured to penetrate through the circuit board, extending from the first conductor pattern to the second conductor pattern, and to constitute a second portion of the second wiring.
An image forming apparatus comprising:
- a rotation member configured to rotate to form an image on a sheet,
- a drive source, and
- a circuit board to which a first integrated circuit or a second integrated circuit is provided,
- wherein the circuit board comprises:
- an electric part provided to a first surface of the circuit board;
- a first attachment part provided to the first surface, to which at least one terminal of the first integrated circuit is attachable;
- a first conductor pattern formed on the first surface and configured to constitute at least a portion of a first wiring which connects the first attachment part and the electric part;
- a second attachment part provided to a second surface opposite to the first surface of the circuit board, to which at least one terminal of the second integrated circuit is attachable;
- a second conductor pattern formed on the second surface and configured to constitute at least a first portion of a second wiring which connects the second attachment part and the electric part;
- and
- a connection via configured to penetrate through the circuit board extending from the first conductor pattern to the second conductor pattern, and to constitute a second portion of the second wiring.
