Definitions

  • ABSTRACT A paper roll su pplies a paper band through an inlet opening in the housing of a business machine to a which transports the paper band back towards the paper roll.
  • PAPER GUIDING ARRANGEMENT FOR BUSINESS MACHINE IPAPIER GUIDING ARRANGEMENT FOR A BUSINESS MACHINE BACKGROUND OF THE INVENTION It is known to support paper roll resting on a housing wall on a pivoted carrier which moves downward as the diameter of the paper roll is decreased by supplying a paper band through an inlet opening of the housing to a platen which transports the paper band back towards and over the top of the paper roll.
  • Another object of the invention is to provide a paper guidtomatically covering the inlet opening of the housing when the diameter of the paper roll has .been reduced so that a paper band unwound from the paper roll can still enter through an inlet opening in the housing, while the free end of the paper band is prevented from entering the inlet opening.
  • Another object of the invention is to improve a known paper guiding arrangement by novel and unobvious structure of great simplicity serving the purpose of preventing a malfunction frequentlyoccurring when the diameterof the paper roll is reduced.
  • the carrier of the paper roll is provided with a closure means which covers the inlet opening through which the paper band passes to such an extent that the paper band can still be supplied to the platen, but cannot reenter the inlet opening after having passed around the platen.
  • One embodiment of the invention comprises a platen mounted in a housing having an inlet'opening, carrier means for rotatably supporting a paper roll in a position resting on the housing and being mounted from movement between a first position in which the carrier means is held by a paper roll having a great diameter, and a second position in which the carrier means is held by a paper roll having a small diameter, and resting on the housing, and a closure meansconnected or fixedly secured to the carrier means for movement with the same and substantially uncovering, and substantially covering, the inlet opening in the first and second positions, respectively, of the carrier means.
  • the arrangement is such that the paper band curved to a small diameter on a paper roll having a small diameter cannot reenter into the inlet opening after having passed about the platen.
  • the closure means When the inlet opening of the housing is substantially covered by the closure means, the same rests on the supplied paper band and on a paper guide supporting the paper band.
  • the carrier means includes two arms located on opposite sides of the paper roll and having journals projecting into a center opening of the same so that the paper roll is supported for turning movement on the carrier means.
  • the closure means is preferably a bar fixedly secured to the arms and extending between the same so that the closure bar moves with the carrier means whereas the diameter of the paper roll is progressively reduced due to the supply of thepaper band to the platen.
  • a particularly inexpensive and simple construction is obtained when the carrier means and closure bar together form an integral body, which is advantageously molded of a thermoplastic synthetic material.
  • FIG. 1 is a fragmentary vertical sectional view illustrating an embodiment of the invention.
  • FIG. 2 is a fragmentary perspective view illustrating the rear portion of a business machine provided with embodiment of the invention shown in FIG. ll.
  • the housing 1 of the business machine includes vertical supporting walls 1a carrying a shaft 2 on which a carrier 3 for a paper roll 8 is mounted for angular movement about the axis of shaft 2.
  • Carrier 3 includes a hollow sleeve 4 turnable on shaft 2 and a pair of arms 5 and 6 having journal portions 7 projecting into a central opening in paper roll 8 and supporting the same for turning movement.
  • a closure bar 9 is secured to the arms 5 and 6 and extends between the same so that turning of carrier 3 about shaft 2 will cause up and down movement of closure bar 9.
  • the lower edge 9a of closure bar 9 projects downward below the lower edges 10 and 11 of the arms 5 and 6.
  • sleeve 4, arms 5 and 6, journal 7, and closure bar 9 as an integral body consisting of thermoplastic synthetic material.
  • the lower peripheral portion of paper roll 8 rests on a wall portion 18a of housing ll when the roll still has a great diameter, as shown in solid lines, but when the diameter of the roll has been reduced, the lower portion of the roll rests on a curved wall portion 18, as shown in chain lines.
  • journals 7 move downward, and carrier 3 pivots downward about shaft 2 from a first higher position to a second lower position.
  • the closure bar 9 is located within the housing 1 adjacent an inlet opening which is formed between the edges of a pair of housing wall portions 17 and 17a.
  • a paper guide 12 is mounted for angular movement about a stationary shaft 13 supported on housing walls la.
  • a pressure roller 16 is mounted for turning movement on paper guide 12 and cooperates with a cylindrical conventional platen 20 mounted for turning movement on housing walls 1a.
  • the paper band 19 is guided from the lower peripheral portion of paper roll 8 through the inlet opening between wall portions 17 and 17a, over the top of paper guide 12, between platen 20 and pressure roller 16, and about platen 20 to pass between the same and a paper holder 14 by which the paper band 19 is guided toward and over the top of a full paper roll I8.
  • Paper holder 14 is mounted for angular movement on shaft 2 and has a portion abutting a portion of paper guide I2.
  • a pressure spring 15 urges paper guide 12 toturn in counterclockwise direction about shaft 13 so that the pressure roller 16 resiliently engages'platen 20.
  • the pressure of spring 15 can be adjusted to operation of manual adjusting means 15a.
  • Spring 15 also acts through paper guide 12 to bias paper holder 14 in counterclockwise direction into engagement with paper band 19 on platen 20.
  • pressure roller 16 is also moved away from platen 2i) and paper band 19 can be freely moved about theplaten.
  • carrier 3 When a full paper roll 8 having a great diameter is placed on the journals 7, carrier 3 is raised to a position determined by the diameter of the paper roll whose lower peripheral portion rests on the housing. Paper band I9'unwound from roll 1% is inserted into the housing through the space between wall portion 170 and the lower edge 90 of closure bar 9, and is placed on the top surface of paper guide 12, and inserted between pressure roller or pressure rollers 16 and platen 20.
  • closure bar 9 moves downward with carrier 3, and more specifically with arms 5 and 6 as the diameter of paper roll 8 is progressively reduced.
  • carrier 3 is in the lower position shown in chain lines in FIG. 1, and the lower edge 9a of closure bar 9 rests on the unwound paper band and through the same on the paper guide 12 as shown in chain lines in FIG. 1.
  • closure bar 9 of the invention does not prevent the use of a new paper roll of small diameter. It is only necessary to slightly raise a small paper roll together with closure bar 9 so that carrier 3 and closure bar 9 assume the higher position as shown in FIG. 1, whereupon the paper band can be unwound from the lower portion of the small paper roll and inserted between the lower edge 9a of closure bar 9 and paper guide 12.
  • closure bar is used in the present application in a descriptive manner, and it will be understood that any closure means for covering the inlet opening of the housing and connected with the carrier 3 may be used.
  • a cylindrical rod, or a comb-shaped plate may be used instead of bar 9.
