A printing apparatus 10 includes support member 12 that supports a core body Ra of a roll medium R, a transport mechanism 17 that transports the print medium S drawn out from the roll medium R, a first accommodation sidewall 27 and a second accommodation sidewall 28 arranged in a width direction, a print head 22, and a trailing edge detection section 60 that detects that all of the print medium S that is drawable out from the roll medium R has been drawn out by the transport mechanism 17, wherein the first accommodation sidewall 27 has groove 50, and the roll medium R is accommodated in an accommodation section 11 by engaging the support member 12 with the groove 50 and the trailing edge detection section 60 detects that the support member 12 is separated from an engagement surface 52 of the groove 50.

An assembly for feeding backing ribbon for adhesive labels for labeling products to be labeled, comprising a splicing device and at least two supporting elements for the backing ribbon, the splicing device being intended to perform on command the splice between a first splicing region, formed on a first backing ribbon being unwound from a first supporting element, and a second splicing region, formed on a second backing ribbon wound on a second supporting element, the first backing ribbon supporting a plurality of adhesive labels which are arranged, mutually spaced, on the face directed toward the second splicing region; the first backing ribbon having, when associated with the respective first supporting element, at least one portion that is free from self-adhesive labels and forms the first splicing region; the portion is located substantially at the end of the first backing ribbon that is associated with the first supporting element.

Disclosed are a paper discharging mechanism and printing device having the same. The paper discharging mechanism includes: a frame provided with a paper outlet thereon; a swinging rack, configured to be swingable relative to the frame; a conveying roller assembly provided on the swinging rack; a first drive assembly, which is in a transmission connection with the conveying roller assembly and configured to drive the same to deliver a paper to the paper outlet; a first detection assembly, configured to detect a position of the swinging rack relative to the frame; the swinging rack swings in a direction away from the paper outlet when the paper outlet is blocked.

Provided is a sheet material end detection mechanism including: a sheet material information part indicating information on a sheet material wound around a core member in which a through hole is formed; a reader configured to optically read the sheet material information part; and a detection unit configured to detect that the sheet material is used up. The sheet material information part extends from a portion corresponding to the through hole at an end of the sheet material wound around the core member to a portion adjacent to the through hole on an inner surface of the core member. The detection unit detects that the sheet material is present when a read signal of the sheet material information part read by the reader is received and that the sheet material is used up when the read signal disappears.

Provided is a sheet material end detection mechanism including: a sheet material information part indicating information on a sheet material wound around a core member in which a light passing part is formed; a reader configured to optically read the sheet material information part; and a detection unit configured to detect that the sheet material is used up. A forming part is attached to an outer surface of the core member and an inner surface of the sheet material. The sheet material information part is formed in a portion of the forming part corresponding to the light passing part. The detection unit detects that the sheet material is present when a read signal of the sheet material information part read by the reader is received and that the sheet material is used up when the read signal disappears.

Provided is a sheet material end detection mechanism including: a sheet material information part indicating information on a sheet material wound around a core member in which a light passing part is formed; a reader configured to optically read the sheet material information part; and a detection unit configured to detect that the sheet material is used up. The sheet material information part is held at an end of the sheet material wound around the core member at a position corresponding to the light passing part. The detection unit detects that the sheet material is present when a read signal of the sheet material information part read by the reader is received and that the sheet material is used up when the read signal disappears.

Provided is a bag making and packaging machine having superior workability in film joining work. A bag making and packaging machine is a bag making and packaging machine that uses film having at least one character or a figure printed on its front side, and is equipped with a film roll support unit, a conveyance unit, a bag making unit, and a light emitting component. The film roll support unit supports a film roll in which the film is wound in a roll. The bag making unit processes the film to make bags. The conveyance unit is positioned between the film roll support unit and the bag making unit. The conveyance unit feeds the film to the bag making unit. The light emitting component illuminates, from the direction of the front side of the film, the film positioned between the film roll support unit and the conveyance unit.

A plurality of marks (11) equidistantly provided on both side edge parts (1a) of a long medium (1), a plurality of first indicator holes (12) equidistantly given on at least one of the side edge parts (1a), and a plurality of second indicator holes (13) given on at least one of the side edge parts (1a) on a straight line different from a row of the first indicator holes (12) at spacings shorter than spacings of the first indicator holes (12) are provided, and the second indicator holes (13) are each provided to a side of a trailing-end mark (11b), and each gradually comes closer to a leading-end mark (11a) as the long medium (1) runs toward a trailing end.
