Integrated adjustable core support and medium guide device

An apparatus for mounting print media rolls of different core diameters, said apparatus comprising:

• a first support member having a first print media holding section comprising a first print media core support ear having a fixed upper portion and a lower portion adapted for vertical positional adjustment relative to said fixed upper portion to receive print media rolls of different core diameters, each of said upper and lower portions of said first print media core support ear being semi-circular-shaped of the same diameter, said first print media core support ear being circular-shaped when said lower portion of said first print media core support ear is positioned directly adjacent said upper portion of said first print media core support ear;
• and
• a second support member disposed opposite said first support member and having a second print media holding section comprising a second print media core support ear having a fixed upper portion and a lower portion adapted for vertical positional adjustment relative to said fixed upper portion to receive print media rolls of different core diameters, each of said upper and lower portions of said second print media core support ear being semi-circular-shaped of the same diameter, said second print media core support ear being circular-shaped when said lower portion of said second print media core support ear is positioned directly adjacent said upper portion of said second print media core support ear, wherein said second print media core support ear further comprises a nob coupled to said lower portion of said second print media core support ear for adjusting the vertical position of said lower portion, said lower portion:comprises a handle post perpendicularly extending through a vertical slot of said second support member for coupling with said nob, said handle post being tightly movable along said vertical slot.

An apparatus for mounting print media rolls of different core diameters, said apparatus comprising:

• a left support member having a first print media holding section which comprises a first print media core support ear having a fixed upper portion and a lower portion adapted for vertical positional adjustment relative to said fixed upper portion to receive print media rolls of different core diameters and a first print media guiding section-coupled to said first print media holding section;
• a right support member disposed opposite said left support member and having a second print media holding section which comprises a second print media core support ear having a fixed upper portion and a lower portion adapted for vertical positional adjustment relative to said fixed upper portion to receive print media rolls of different core diameters and a second print media guiding section coupled to said second print media holding section;
• and
• a connecting mechanism coupled between said left and right support members, said connecting mechanism adapted to adjust the spacing between said left and said right support members, said first print media guiding section comprises:
• a fixed guiding wall;
• a curved guiding rail perpendicularly coupled to said guiding wall at a bottom end;
• and
• a flat guiding cap perpendicularly coupled to said guiding wall at a front end, said guiding cap being horizontally angled down approximately 10°-20° relative to said front end.

A media holder comprising:

• a media support member having a recess;
• a first media core support portion fixedly coupled to said media support member at one end of said recess;
• and
• a second media core support portion movably coupled to said media support member and adapted for positional adjustment within said recess relative to said first media core support portion between a first position in which said second media core support portion is disposed adjacent said first media core support portion and a second position in which said second media core support portion is disposed at an opposite end of said recess,
• said first and second media core support portions forming an adjustable media core support for mounting media rolls of different core diameters.
