Definitions

  • the present invention relates to a feeding and delivery structure for a cutform medium (e.g., a single sheet or film) for use with a printer having an automatic feeder for cutform media.
  • a cutform medium e.g., a single sheet or film
  • Document JP-A-2 286 269 shows an adjustable sheet guide for feeding recording media of various sizes to a printer.
  • a switch is included in the feeder to detect when postcard size media are used.
  • Another conventional device disclosed in Japanese Examined Patent Publication No. 63-53091 and as shown in Fig. 4 of the present application, has a cutform medium fed by an automatic feeder 101 disposed upstream of a platen 105, and conveyed by the platen and pressing rollers 106, 107.
  • the cutform medium is printed by a printing head 108 opposed to the platen 105, delivered upwardly by delivery rollers 109, 110 and stored in a stacker 111.
  • Such a printer is suitable for successive (e.g., continuous) processing of cutform media.
  • a single cutform medium different from those stored in the automatic feeder 101 is to be processed, the processing and handling thereof is troublesome. To eliminate this inconvenience, a sheet passage 112 for manual feeding and a manual feed guide 102 have been provided.
  • the manual feed guide 102 for the cutform medium also serves as a rear face of the stacker adapted to store the cutform medium having been printed by the print head 108, and is located on the same plane as the printed cutform medium.
  • a problem arises in that, if the cutform medium has a tendency to roll-up, a tip 104a of the cutform medium is rolled into the sheet passage 112 due to a rear or trailing end of the cutform medium remaining in the sheet passage.
  • Another problem in the conventional feeding and delivery structure is that the surface of the delivered cutform medium 104 is brought into contact with the rear face of the stacker. Therefore, when the cutform medium is electrostatically charged in a low humidity environment, the attraction of the cutform medium 104 to the stacker face increases. Hence, a comparatively thin cutform medium is buckled due to a force couple generated by the conveying force of the delivery rollers 109, 110 (e.g., indicated by arrow a in Figure 4) and the carrying load on the rear face of the stacker (e.g., as indicated by arrow b), and cannot be properly conveyed by the delivery roller 109.
  • An object of the present invention is to solve the above-mentioned problems of the conventional device, and to provide a feeding and delivery structure for a cutform medium which enables the cutform medium to be safely and reliably delivered without being rolled into a sheet passage, even if it has a tendency to roll-up during its conveyance.
  • Another aspect of the present invention is to provide a feeding and delivery structure for a cutform medium which enables a comparatively thin cutform medium to be delivered reliably.
  • a feeding and delivery structure for a cutform medium in a printer in which an automatic feeder for cutform media is disposed at a rear portion of a platen, includes delivery rollers disposed at upper portions of the platen, a stacker bottom face member provided at a rear portion of the delivery rollers and forming a stacker for storing delivered cutform media, and guide members slideably attached in the horizontal printing direction to front faces of guide plates provided at the front of the automatic feeder.
  • the guide members guide the side edges and the front face of a manually fed cutform medium and have front faces forming a rear face of the stacker.
  • the guide members may also have ribs formed on their front faces.
  • Fig. 1 is a sectional view of a feeding and delivery structure for a cutform medium according to a first embodiment of the present invention.
  • Fig. 2 is a partial perspective view of the feeding and delivery structure for a cutform medium of the first embodiment of the present invention.
  • Fig. 3 is a sectional view of a second embodiment of the present invention.
  • Fig. 4 is a sectional view of a conventional feeding and delivery structure for a cutform medium.
  • a cutform medium 4 fed by an automatic feeder 1 is conveyed by a platen 5 and pressing rollers 6, 7. Thereafter, the cutform medium 14 is printed by a printing head 8 opposed to the platen 5, passes between delivery rollers 9, 10 located above (e.g., upstream) the platen, and is delivered along front faces 3a of guide members 3 and stored in a stacker formed by a bottom face member 11 and the front faces 3a of the guide members.
  • the bottom face member is secured at one end to a shaft supporting delivery roller 9.
  • the guide members (3) are slideably supported by guide plates 2 as evident from Figure 2 in a direction S perpendicular to the feed direction of the cutform medium 4 in order to allow adjustment to cutform media 4 of different width.
  • the guide members 3 thus provide adjustable opposite U-type channels facing one another for delivering the manually fed cutform medium 4 to the printer. These channels preferably end below and behind the upper end of the bottom face member 11 which together with the free parts of the front faces 3a of the guide members 3 form the stacker for the printed cutform medium 4, as shown in detail in Figure 2.
  • the cutform medium 4 When a cutform medium 4 different from that stored in the automatic feeder 1 is to be printed, the cutform medium 4 is manually fed, with its side edges and its front face being guided by the guide members 3 and front faces 2a of guide plates 2 disposed in front of the automatic feeder 1. The cutform medium 4 is guided to a normal position by guiding its edges. Similarly to when the cutform medium 4 is fed by the automatic feeder 1, it is subsequently carried and conveyed by the platen 5 and the pressing rollers 6, 7.
  • the cutform medium After the cutform medium is printed by the printing head 8, it passes between the delivery rollers 9, 10 located upstream of the platen 5 and is delivered along the front face portions 3a of the guide members. Even if the cutform medium 4 has a tendency to roll up due to its conveyance by the platen 5, since a sheet feed passage is separated from a sheet delivery passage by the guide members 3, an upper end 4a of the delivered cutform medium is prevented from rolling into the sheet feed passage again because of a cutform medium 4 remaining in the sheet feed passage. Thus, the delivered cutform medium can be stored reliably and easily in the stacker formed by the stacker bottom face member 11 and the front face portions 3a of the guide members.
  • FIG. 3 Another embodiment of the invention, as shown in Fig. 3, illustrates a feeding and delivery structure for a cutform medium in which ribs 12 are formed on the front faces 3a of the guide members 3.
  • the attraction of the cutform medium 4 carried along the guide members 3 to the stacker face is reduced since the frictional and electrostatic forces created (e.g., in a low humidity environment) are reduced.
  • a comparatively thin cutform medium may be employed as compared to that of the conventional system, and a stable sheet feed operation may be performed.
  • a manual sheet feed passage and a sheet delivery passage of the cutform medium are separated by guide members for guiding the edges and front face of the cutform medium, so that the cutform medium is prevented from rolling into the feed passage during the manual feeding thereof.
  • the ribs are formed on the front faces of the guide members, a thinner cutform medium can be reliably delivered.
