  • Publication number: 20250001775
    Abstract: An auxiliary member is configured to be attachable to and detachable from a support member. An operation section performs, switching from the position adjustment state in which movement of the support member is allowed in the extending direction of the shaft member to the positioned state in which movement of the support member with respect to the shaft member in an extending direction of the shaft member is limited and, in conjunction, switching from an unlocked state in which a lock section does not contact an inner peripheral section of the roll medium to a locked state in which the lock section contacts the inner peripheral section of a roll medium. By being attached to the support member, the auxiliary member sets the support member into the positioned state even when the operation section is in the position adjustment operation position.
