Definitions

  • This invention is directed to systems including devices, such as typewriters, which utilize at least two different cassettes, such as a typewritter ribbon cassette and a correction cassette.
  • U.S. Pat. No. 4,636,097 includes means for rendering the printer inoperable when the end of the typewriter ribbon in a cassette is sensed, or when there is no cassette in the printer.
  • Another such device is disclosed in IBM Technical Disclosure Bulletin, Vol. 25, No. 4, September 1982.
  • the cassette disclosed therein provides a signal to the device (such as a typewriter) which identifies the contents of the cassette, so that the device may adjust to the characteristics of the cassette contents.
  • Still another such device is disclosed in U.S. Pat No. 4,516,137 wherein the presence or absence of a thermal ribbon cassette is sensed by the printer. If a thermal ribbon cassette is present, the printer can print only undirectionally, whereas when the ribbon cassette is not present, the printer prints bi-directionally.
  • Patent Abstracts of Japan, Vol. 10, No. 216 (M-502) [2272], re. JP-A1-6154975, describes a system wherein the presence or absence of a detector on an ink ribbon cassette in a device is used (via a selection switch 24) to select an appropriate printing pressure in that device.
  • Patent Abstracts of Japan Vol. 9, No. 98 (M-375) [1821], re JP-A-59222380, describes a system wherein a tab/pair of tabs is provided on each monocolour ribbon cassette of the system so as to activate switches when inserted into a device to identify to that device the colour of the ribbon in the inserted cassette.
  • a typewriter ribbon cassette includes a plastic jacketing in which the ribbon and various components are conveniently housed. These components may include, among other things, a supply spool upon which a supply of typewriter ribbon is located, mechanism for assuring the uniform withdrawal of ribbon from the supply spool to the typewriter print point, and a take-up spool on which the typed ribbon is located.
  • a typewriter drive mechanism rotates the take-up spool to cause fresh ribbon from the supply spool to advance to the print point.
  • a typewriter ribbon cassette of this type is disclosed in U.S Pat. No. 4,302,118.
  • Such typewriter ribbon cassettes may contain various types of ribbons.
  • the ribbon may be of the single-strike carbon ribbon type or of the multiple-strike carbon ribbon type. If the ribbon is a single-strike carbon ribbon, the ribbon is incrementally fed in such a manner that upon a single character being typed on a portion of the ribbon, the ribbon is advanced so that the next character is typed on a fresh portion of the ribbon.
  • the ribbon is a multiple-strike ribbon, such as the "Multi-Strike" ribbon sold by Smith Corona Corporation, the ribbon is incrementally fed in such a manner that upon a character being typed on a ribbon, the ribbon is advanced a lesser distance so that the next character is typed on a ribbon portion comprising both a typed ribbon portion and a fresh ribbon portion. In this manner, significantly more characters may be typed on a multiple-strike ribbon than on a single-strike ribbon.
  • a typewriter correcting cassette may also include a plastic jacketing for conveniently housing a correcting tape and various components.
  • the components of a correcting cassette may include a supply spool, means for assuring the uniform withdrawal of correcting tape from the supply spool, and a take-up spool.
  • the correcting tape may be of two types, namely, the type commonly referred to as "lift-off” tape, in which the tape, upon striking the unwanted character, removes the unwanted character from the paper, or the type commonly referred to as "cover-up” tape, in which, upon the tape striking the unwanted character, a powdered material on the tape is transferred to and covers up the unwanted character on the paper.
  • the cassette with means for assuring that the cassette is functionally compatible with the corresponding second cassette of the combination or assembly upon the cassettes being inserted into a device, such as a typewriter in a system which utilizes the cassettes.
  • the means for assuring cassette compatibility will prevent the first cassette from being properly placed in the device and indicating to the operator that an attempt is being made to place into the device a cassette which is not compatible with another being so placed.
  • the present invention provides a system utilising a cassette assembly including selectively combinable first and second cassettes, said system comprising in combination: a device in which an assembly of a first and a second cassette are inserted for operation of the device; a first cassette for use in said device,said first cassette having an ink ribbon; and a second cassette for use in said device, said second cassette having a correction tape ; characterised in that there is further provided compatibility means comprising: a first structural feature provided on said first cassette at a location corresponding to the type of ink ribbon in said first cassette, a second structural feature provided on said second cassette at a location corresponding to the type of correction tape in said second cassette, the first and second structural features being adapted for inhibiting the proper mounting of said first and second cassettes in the device unless the ink ribbon in the first cassette is compatible with the correction tape in the second cassette.
  • the present invention further provides a method for assembling a system including a device and at least one assembly of selectively combinable first and second cassettes adapted for insertion into the device, the method comprising the steps of: providing the first cassette with an ink ribbon ; providing the second cassette with a correction tape ; and inserting the first and second cassettes into the device; characterised in that there is further provided the step of providing on said cassettes compatibility means, said compatibility means being disposed on said first and second cassettes in assembly-specific locations corresponding to the type of ribbon in said first cassette and the type of correction tape in said second cassette for inhibiting cassettes having incompatible ink ribbon and correction tape combinations from being properly placed in said device.
  • Cassette compatibility is also achieved, in general, by providing a switch means in the typewriter, printer, or the like, which controls the on - off condition of the typewriter, and means located on the ribbon cassette that activates the on-off typewriter switch means.
  • the ribbon cassette activating means will not activate the on-off typewriter switch when functionally incompatible cassettes are present in the typewriter.
  • the ribbon cassette activating means will activate the on-off typewriter switch only when either a single-strike ribbon cassette and a cover-up correction tape cassette are present in the typewriter or when a multiple-strike ribbon cassette and a lift-off correction tape cassette are present in the typewriter.
  • a first typewriter ribbon cassette 2 having a housing 4 within which a first typewriter ribbon 6 (which may be of the single-strike carbon ribbon type), and various other components, are housed.
  • a formation 8, such as a tab, extends from the right-hand portion of the bottom of the housing 4 for a purpose to be described hereinafter.
  • a single-strike carbon ribbon is of the type which is incrementally fed in such a manner that upon a character being typed on a ribbon portion, the ribbon is advanced so that the next character is typed on a fresh portion of the ribbon.
  • These components may include, among other things, a supply spool upon which a typewriter ribbon supply is located, a mechanism for assuring the uniform withdrawal of ribbon from the supply spool to the typewriter print point, and a take-up spool on which the typed ribbon is located.
  • a supply spool upon which a typewriter ribbon supply is located a mechanism for assuring the uniform withdrawal of ribbon from the supply spool to the typewriter print point, and a take-up spool on which the typed ribbon is located.
  • a cassette is presently being sold by Smith Corona Corporation under its "H Correctable" mark.
  • a first correction tape cassette 10 which is functionally compatible with the first typewriter ribbon cassette 2, and within which a first correction tape 12 of, for example, the lift-off type, together with other components, is housed.
  • the ribbon cassette 2 and the functionally compatible correction cassette 10 may be designated a cassette combination or assembly.
  • Typewriter actuating means causes the type element to strike the lift-off tape against the unwanted character on the paper, and the lift-off tape withdraws the unwanted character from the paper.
  • the components (not shown) in the first correction tape cassette 10 may include a supply roll of correcting tape, means for assuring the uniform withdrawal of correcting tape from the supply spool and a take-up spool.
  • the first correction tape cassette 10 also includes a flat portion 14 having a formation 16 illustrated as an opening, in the right-hand portion, through which the tab formation 8 of the first typewriter ribbon cassette 2 extends when the cassettes are inserted into the typewriter.
  • Fig. 1 further discloses a shiftable bracket section 18 adapted to operationally accommodate the first typewriter ribbon cassette 2 and the first correction tape cassette 10 thereon.
  • the shiftable bracket section 18 is pivotable about pivot points 20 by conventional typewriter means (not shown) for presenting either the first typewriter ribbon 6 or the lift-off first correction tape 12 to the typewriter print point.
  • the engagement of the tab formation 8 of the ribbon cassette 2 with the opening formation 16 of the first correct tape cassette 10 ensures that the cassettes are compatible with each other.
  • the cassettes 2 and 10 are configured so that unless the formations 8 and 16 are in operational engagement, the cassette assembly will not be capable of being inserted in the typewriter. Consequently, the typewriter will be inoperable.
  • Fig. 2 shows a second typewriter ribbon cassette 2a and a second correction tape cassette 10a which are generally similar in construction to the first typewriter ribbon cassette 2 and the first correction tape 10 shown in Fig. 1. Therefore, in large part, the same numerical reference numerals will be used in Fig. 2 as were used in Fig. 1, except that the letter "a" will be added to the reference numerals of Fig. 2.
  • a second typewriter ribbon cassette 2a having a housing 4a within which a second typewriter ribbon 6a, which may be of the multiple-strike carbon ribbon type, and various other components are housed.
  • a formation 44 such as a tab extends from the left-hand portion of the bottom of the housing 4a for the purpose to be hereinafter described.
  • a multiple-strike carbon ribbon is of the type which is incrementally fed in such a manner that upon a character being typed on a ribbon portion, the ribbon is advanced so that the next character is typed on a ribbon portion comprising both a typed ribbon portion and a fresh ribbon portion.
  • These components may include, among other things, a supply spool upon which a typewriter ribbon supply is located, mechanism for assuring the uniform withdrawal of ribbon from the supply spool to the typewriter print point, and a take-up spool on which the typed ribbon is located.
  • a supply spool upon which a typewriter ribbon supply is located may include, among other things, a supply spool upon which a typewriter ribbon supply is located, mechanism for assuring the uniform withdrawal of ribbon from the supply spool to the typewriter print point, and a take-up spool on which the typed ribbon is located.
  • a cassette is presently being sold by Smith Corona Corporation under its "H Multi-Strike" mark.
  • the second correction tape cassette 10a which is functionally compatible with the second typewriter ribbon cassette 2a, and within which a second correction tape 12a of, for example, the cover-up type, together with other components, is housed.
  • the ribbon cassette 2a and the functionally compatible correction cassette 10a may be designated a cassette combination or assembly.
  • Typewriter actuating means causes the type element to strike the cover-up tape against the unwanted character on the paper, and the cover-up tape is transferred to and covers up the unwanted character.
  • the components (not shown) in the second correction tape cassette 10a may include a supply roll of correcting tape, means for assuring the uniform withdrawal of correcting tape from the supply spool, and a take-up spool.
  • the second correction tape cassette 10a also includes a flat portion 14a having a formation 46 illustrated as an opening in the left-hand portion, through which the tab 44 of the second typewriter ribbon cassette 2a extends when the cassettes are inserted into the typewriter.
  • the shiftable bracket section 18 shown in Fig. 2 is the same bracket section shown in Fig. 1.
  • the engagement of the tab formation 44 of the ribbon cassette 2a with the opening formation 46 of the second correct tape cassette 10a ensures that the cassettes are compatible with each other.
  • the cassettes 2a and 10a are configured so that unless the formations 44 and 46 are in operational engagement, the cassettes will not be capable of being inserted in the bracket section 18. Consequently, the typewriter will be inoperable.
  • cassette compatibility may further be assured in a typewriter which has an on-off switch means as illustrated in Figs. 3-7.
  • Figs. 3, 5 and 7 show the first typewriter ribbon cassette 2 and the first correction tape cassette 10 of Fig. 1, thus in large part the same numerical reference numerals will be used in Figs. 3, 5 and 7 as were used in Fig. 1.
  • Fig. 4 shows the second typewriter ribbon cassette 2a and second correction tape cassette 10a of Fig. 2, thus in large part the same numerical reference numerals will be used in Fig. 4 as were used in Fig. 2.
  • the shiftable bracket section 18 has an opening 22 and an opening 24 in a front portion 26.
  • a clip 28 is clamped to the shiftable bracket section 18.
  • An on-off switch rocker 30 (the operation of which will be described hereinafter) is assembled to the shiftable bracket section 18 by means of a first finger 32 of the on-off switch rocker 30 extending through the opening 24 of shiftable bracket section 18.
  • a notch 34 in switch rocker 30 receives a wall portion 36 of the opening 24.
  • the first finger 32 seated against the wall portion 36 provides a first pivot point for the on-off switch rocker 30.
  • a second finger 38 of the on-off switch rocker 30 extends through the opening 22 in shiftable bracket section 18 and abuts against a wall portion 40 of the opening 22 to provide a second pivot point for the on-off switch rocker 30.
  • the second finger 38 is integrally molded with the on-off switch rocker 30 in such a manner that the second finger 38 is biased against the wall portion 40 and causes the first finger 32 to be biased against the wall portion 36 for holding the on-off switch rocker 30 assembled to the shiftable bracket section 18.
  • the first pivot point of the first finger 32 is substantially in alignment with the second pivot point of the second finger 38 to provide a common axis 42 for pivoting the on-off switch rocker 30 relative to the shiftable bracket section 18.
  • the shiftable bracket section 18 shown in Fig. 4 is the same bracket section shown in Fig. 3.
  • the on-off switch rocker 30 shown in Fig. 5 includes a generally planar portion 48 having two rearwardly extending arms 50 on which an upwardly extending right-hand finger 52 and an upwardly extending left-hand finger 54 are located.
  • a spring means 56 is connected at one end to the on-off switch rocker 30 and at its opposite end to the shiftable bracket section 18 at spring aperture 58. The spring 56 biases the on-off switch rocker 30 counterclockwise about the common axis 42.

  • the second switch contact 64 has an elongated contact surface with the elongation arranged substantially perpendicular relative to the first switch contact 62.
  • the contacts may be of different shapes, it has been found desirable to make the shapes elongated to reduce the manufacturing tolerances required to have the first switch contact 62 efficiently contact the second switch contact 64 during initial assembly and during continual typewriter operation thereafter.
  • the first and second switch contacts 62 and 64 are connected to electronics 66 mounted in the typewriter by lead lines 68.
  • the electronics 66 is connected to a power source for controlling the flow of electricity to the typewriter.
  • the spring 56 biases the on-off switch rocker 30 counterclockwise relative to the shiftable bracket section 18 to bias the first switch contact 62 in contact with the second switch contact 64 for closing the switch 60.
  • the switch 60 is closed when neither the first typewriter ribbon cassette 2 nor the second typewriter ribbon cassette 2a is inserted in the typewriter.
  • the electronics 66 senses that the switch 60 is closed and thereby prevents the flow of electricity to the typewriter.
  • the tab 8 contacts the right-hand finger 52 and pivots the on-off switch rocker 30 clockwise relative to the shiftable bracket section 18 to open the switch 60.
  • the tab 44 contacts the left-hand finger 54 and pivots the on-off switch rocker 30 clockwise to open the switch 60 (Fig. 4 ).
