Abstract
A circuit board unit includes a circuit board, and a relay. The circuit board includes an exposed terminal. The relay contacts the exposed terminal in a conductive manner. The relay includes a first contact and a second contact. The first contact contacts the exposed terminal. The second contact is disposed at a position away from the first contact and contacts and separates from a terminal of an apparatus in conjunction with attachment and detachment of the circuit board unit to and from a body of the apparatus. The relay relays conduction between the exposed terminal and the terminal that contacts the second contact.
Claims20
A circuit board unit comprising:
- a circuit board including an exposed terminal;
- and
- a relay contacting the exposed terminal in a conductive manner,
- wherein the relay includes:
- a first contact contacting the exposed terminal;
- and
- a second contact disposed at a position away from the first contact and configured to contact and separate from a terminal of an apparatus in conjunction with attachment and detachment of the circuit board unit to and from a body of the apparatus, and
- wherein the relay is configured to relay conduction between the exposed terminal and the terminal that contacts the second contact.
An attachment unit comprising:
- a circuit board including an exposed terminal;
- a relay contacting the exposed terminal in a conductive manner;
- and
- a holder holding the circuit board and the relay in a state in which a first contact of the relay is in contact with the exposed terminal,
- wherein the relay includes a second contact at a position away from the first contact, the second contact being configured to contact and separate from a terminal of an apparatus in conjunction with attachment and detachment of the attachment unit to and from the apparatus, and
- wherein the relay is configured to relay conduction between the exposed terminal and the terminal that contacts the second contact.
