  • FIG. 1 is a side-lateral view of the internal structure of a printer according to an embodiment.
  • the printer which prints information on strip paper rolled into a roll, is provided with a printer main body 1 which can be horizontally or longitudinally mounted.
  • the printer main body 1 may be optionally mounted on a desk or hung on a wall.
  • FIG. 1 shows the horizontal mounting of the printer main body on a desk
  • FIG. 2 shows the longitudinal hanging of the printer main body on a wall.
  • the wider side 2 of the printer main body 1 in width direction is a mounting section 3 for mounting the printer main body 1 horizontally on a desk or longitudinally on a wall.
  • the printer main body 1 has an outer cover 7 that can be opened or closed by taking a hinge 6 as the center, and a hopper 9 that serving as an accommodation section for accommodating roll paper 8 and a printing section 10 serving as a printer member are arranged in the printer main body 1 .
  • the roll paper 8 consists of strip thermal paper (hereinafter referred to as paper) 8 b that is rolled on a roll core 8 a into a roll.
  • An arc-shaped protrusion surface 7 a is formed on the outer cover 7 to reserve a movement space for the roll paper 8 with the biggest roll diameter.
  • the printing section 10 consists of a platen 12 serving as a feeding section that is rotated under the drive of a platen motor and a thermal head 14 that is propped against the platen 12 under the elastic force of a head spring 13 .
  • a cutter 16 driven by a cutter motor and a sensor 17 for detecting the home position of the cutter 26 are arranged at the downstream side of the printer 10 .
  • a paper end sensor 19 is arranged at the upstream side of the printer 10 and located between the hopper 9 and the platen 12 to detect the existence of the paper.
  • an outer cover opening/closing sensor 20 is arranged on the upper portion of the platen 12 to detect the opening/closing of the outer cover 7 .
  • the hopper 9 has a first holder section 9 a and a second holder section 8 b for supporting the outer peripheral surface of the roll paper 8 .
  • a first recess 22 is formed on the first holder section 9 a
  • a second recess 23 is formed on the second holder section 9 b.
  • the paper 8 b when printing is implemented, the paper 8 b is fed as the platen 12 rotates, and information is printed on the paper 8 b using the thermal head 14 .
  • the printed paper 8 b is conveyed by a given distance to the cutter 16 to be cut into a given size and is then discharged.
  • the hopper 9 is molded based on a minimal draft angle.
  • FIG. 5 is a planar view of the hopper 9 in the printer main body 1 mounted on a desk (shown in FIG. 3 )
  • FIG. 6 is a front view of the bottom-dump hopper of FIG. 5 that is longitudinally cut.
  • the surface of the hopper 9 at the side of the mold stripping direction of the mould is set to be the opening section 25 from where the roll paper 8 is fed to the hopper 9 for accommodation.
  • the first holder section 9 a provided with the first recess 22 is formed on the inner bottom of the hopper 9 .
  • the roll paper 8 with a reduced roll diameter is accommodated in the first recess 22 .
  • the peripheral wall 26 of the hopper 9 is gradually enlarged from the inner bottom part towards the opening section 25 .
  • the peripheral wall 26 of the hopper 9 is gradually enlarged from the inner bottom part towards the opening section 25 , therefore, the clearances between the two ends of the roll paper 8 in width direction and the inner wall of the hopper 9 are gradually widened towards the opening section 25 .
  • the printer main body 1 When the printer main body 1 is mounted on a desk, as the roll paper 8 is held by the first holder section 9 a on the inner bottom of the hopper 9 , the clearances between the two ends of the roll paper 8 in width direction and the inner wall of the hopper 9 are narrow. Therefore, the movement of the roll paper in the width direction of the roll paper is regulated by the inner wall of the bottom-dump hopper, which prevents the occurrence of a position offset. As a result, even the paper 8 b fed from the hopper 9 is conveyed to the printing section 10 and the cutter 16 , the position offset in the width direction of the paper is small enough for an excellent printing and cutoff.
  • the printer main body 1 when the printer main body 1 is hung on a wall, as the roll paper 8 is held by the second holder section 9 b, the roll paper 8 is close to the opening section 25 . Therefore, the clearances between the two ends of the roll paper 8 in width direction and the inner wall of the hopper 9 are widened by the draft angle of the mould, especially, when the diameter of the roll of the roll paper 8 is reduced due to the consumption on the roll paper 8 , the clearance is further widened.
  • the roll paper 8 is likely to be subjected to a severe position offset in width direction, the paper 8 b that is conveyed from the hopper 9 to the printing section 10 and the cutter 16 is also subjected to a severe position offset, resulting in a poor printing and cutoff.
  • a protrusion section 28 is arranged in the hopper 9 to serve as a regulator to regulate the position offset (in width direction) of the roll paper 8 in the hopper 9 .
  • FIG. 7 is a front view of the bottom-dump hopper of FIG. 4 that is longitudinally cut
  • FIG. 8 is planar view of the bottom-dump hopper of FIG. 7 that is horizontally cut.
  • the protrusion section 28 serving as the regulator is wholly inwards protruded on the inner sides of two lateral walls of the second holder section 9 b of the hopper 9 .
  • the protrusion section 28 has an inclined guide side 28 a , along which the roll paper 8 falling under the action of gravity after being consumed and reduced in roll diameter is guided into the second recess 23 .
  • the two ends of the guided roll paper 8 in width direction are clamped between the lower ends of the guide side 28 a, thereby regulating the position offset of the roll paper in width direction.
  • the protrusion section 28 arranged in the hopper 9 can regulate and fix the position of the roll paper 8 in width direction even when the position of the roll paper 8 held in the hopper 9 is changed as the mounting gesture of the printer main body 1 is changed, therefore, the position of the paper 8 b fed from the hopper 9 is stabilized.
  • the paper 8 b in the printing section 10 or cutter 16 is subjected to no position offset and can be therefore printed or cut off excellently.
