Assisting apparatus and recording apparatus

An assisting apparatus comprising:

• a shaft member that is insertable into a winding core of a roll around which a sheet is wound;
• a moving member movable in a vertical direction, the moving member including the shaft member;
• a support member that supports the moving member such that the moving member is movable in the vertical direction;
• and
• an indicator configured to indicate a position of the moving member in the vertical direction by moving in conjunction with movement of the moving member, wherein
• the assisting apparatus is configured to assist in an operation of aligning a position of the roll in the vertical direction in a state in which the shaft member is inserted in the winding core, and
• the indicator includes a mark that enables visual identification that the position of the moving member in the vertical direction reaches a predetermined target position.

An assisting apparatus comprising:

• a shaft member that is insertable into a winding core of a roll around which a sheet is wound;
• and
• a detector configured to detect a relative position between the winding core and the shaft member inserted in the winding core, the detector including the shaft member, wherein
• the assisting apparatus is configured to assist in an operation of aligning a position of the roll in the vertical direction in a state in which the shaft member is inserted in the winding core, and
• the assisting apparatus further comprises a notifier configured to provide a notification when the detector detects that the relative position between the shaft member and the winding core reaches a predetermined target position.

An assisting apparatus configured to assist in an operation of aligning positions in a vertical direction of a rotation shaft of a roll using apparatus and a roll, the rotation shaft being insertable into a winding core of the roll around which a sheet is wound, the roll using apparatus being capable of using the roll in a state in which the roll is attached to the rotation shaft, wherein

• a first end portion of the rotation shaft in an axial direction is fixed to the roll using apparatus, the rotation shaft is insertable into the roll from a side corresponding to a second end portion that is opposite to the first end portion in the axial direction of the rotation shaft,
• the assisting apparatus comprises:
• an imager;
• and
• a display configured to display a captured image captured by the imager, wherein
• the imager is arranged such that images of the second end portion of the rotation shaft and an end portion of the winding core in an axial direction that is closer to the rotation shaft are included in the captured image.

A recording apparatus configured to perform recording on a sheet comprising:

• a rotation shaft that is insertable into a winding core of a roll around which the sheet is wound;
• and
• an assisting apparatus, wherein
• the roll is usable in a state in which the roll is attached to the rotation shaft of the recording apparatus,
• the assisting apparatus comprising:
• a shaft member that is insertable into the winding core of the roll around;
• a moving member movable in a vertical direction, the moving member including the shaft member;
• a detector configured to detect a position of the moving member in the vertical direction;
• and
• a notifier configured to provide a notification when the detector detects that the position of the moving member in the vertical direction reaches a predetermined target position, wherein
• the assisting apparatus is configured to assist in an operation of aligning a position of the roll in the vertical direction in a state in which the shaft member is inserted in the winding core, and
• when the moving member is at the target position, an inner circumference surface of the winding core of the roll and an outer circumference surface of the rotation shaft do not interfere with each other.
