- This invention relates to an ink sheet reel on which an ink sheet used in the heat transfer recording system can be wound, an ink sheet cartridge using said ink sheet reel, and a recording apparatus using these.
- recording apparatus covers, for example, a facsimile apparatus, a typewriter, a copying apparatus and a printer.
- the facsimile apparatus of this heat transfer recording type has the advantages that plain paper or the like can be used as a recording sheet and that images can be recorded clearly.
- a supply reel for supplying an ink sheet and a take-up reel for taking up the ink sheet from the supply reel are loaded into a loading portion such as a recording cover, or the supply reel and the take-up reel as an ink sheet cartridge (hereinafter referred to as the ink cartridge) contained in a container are loaded into the loading portion such as the recording cover, and in order to enable this loading to be accomplished smoothly and easily, there is provided some gap axially of the reels between the supply reel or the take-up reel and the loading portion.
- spur gears are used as power transmission gears of the take-up reel and supply reel sides and power transmission gears of the conveying drive system side. Therefore, if a gap is provided between the supply reel or the take-up reel and the loading portion as previously described, the take-up reel and the supply reel may have lush in the axial direction, and this in turn leads to the disadvantage that oblique movement or skew or wrinkling of the ink sheet and unsatisfactory take-up of the ink sheet are caused.
- axial pressure side pressure
- spring means or the like becomes necessary, and this means an increased number of parts.
- Typical means of the present invention for achieving these object is characterized by being constituted by an ink sheet winding portion on which an ink sheet can be wound, and power transmission means provided in said ink sheet winding portion and creating an axial thrust in said ink sheet winding portion.
- An ink sheet reel on which an ink sheet to which the means of the prevent invention is applied can be wound, an ink sheet cartridge using such ink sheet reel, and a recording apparatus using these will hereinafter be described with respect to a preferred embodiment thereof with reference to the drawings.
- the embodiment described hereinafter is designed such that when a rotational force is transmitted to a gear which is power transmission means, an axial thrust is produced in the ink sheet winding portion of an ink sheet reel and the ink sheet winding portion is pressed toward on axial end side by this thrust and in the loading portion of the recording apparatus side, this ink sheet winding portion is stopped. Also, at this time, it is desirable that the thrust of the ink sheet reel of the supply side and the thrust of the ink sheet reel of the take-up side act in the same direction.

- the recording sheet 1 and an ink sheet 2 overlapping with each other are urged against a platen roller 4 by a recording head 3 as recording means, and by the platen roller 4 being driven in the direction of arrow, the recording sheet 1 is conveyed in the direction of arrow a, and by a driving mechanism 44 which will be described later, the ink sheet 2 is conveyed in the direction of arrow b.
- the recording head 3 is driven in conformity with an image signal, whereby ink applied to the ink sheet 2 is melted (including sublimation) and the melted ink is transferred to the recording sheet 1 to thereby form an image.
- the recording sheet 1 on which a predetermined image has been formed is further conveyed in the direction of arrow a and is cut by a cutter 5, whereafter it is conveyed and discharged out of the recording apparatus A by a pair of conveying rollers 6.
- the recording sheet 1 is contained in a roll holder 8 provided in the apparatus body 7.
- the roll holder 8, the platen roller 4, the cutter 5 and the pair of conveying rollers 6 are provided in the apparatus body 7.
- the ink sheet 2 is inserted in an ink cartridge 9 which will be described later.
- the ink cartridge 9 is removably loaded in a recording cover 11 as a loading portion pivotably constructed in the apparatus body 7 through a pivot shaft 10.
- the recording head 3 is provided at a predetermined location in the recording cover 11.
- the reading system B applies a light to an original 12 and converts the reflected light therefrom into an electrical signal, and transmits this signal to other apparatus or the recording apparatus in conformity with the operation mode.
- a plurality of originals 12 are placed on an original supporting table 13 formed on top of the recording cover 11, and these originals 12 are preliminarily conveyed by a preliminary conveying roller 14a and a pressing roller 14b and are separated and fed one by one by a separating roller 15a and a pressing piece 15b urged thereagainst, and the originals 12 are conveyed by a pair of conveying rollers 16a and 16b and discharged onto a discharge tray 17.
- a light is applied from a light source 18 to the surface of the original 12 while the original 12 is being conveyed, and the reflected light therefrom is caused to pass to a photoelectric conversion element 21 such as a CCD via a mirror 19 and a lens 20, and the image signal thereof is transmitted to the reconding system of the recording apparatus in the case of the copy mode, and is transmitted to the recording system of other apparatus in the case of the transmission mode.
- a photoelectric conversion element 21 such as a CCD via a mirror 19 and a lens 20
- the operation panel C is a panel for performing operations such as the mode switching operation, and is provided with keys for the various operations.
- This operation panel C is provided on the upper portion of an original conveying mechanism in the recording system B, and is constructed for pivoted movement relative to the apparatus body 7.
- One side of the operation panel C is equipped with a telephone set D for effecting transmission and reception.
- the reference numeral 22 designates an electric equipment substrate and the reference numeral 23 denotes a power source unit.
- the recording sheet 1 may be plain paper, plastic film or a sheet of any other material to which ink is transferable.
- a long footage of plain paper of B4 width or A4 width is used as the recording sheet 1.
- a sheet roll 1a comprising the recording sheet 1 wound into the form of a roll is contained in the roll holder 8 provided at a predetermined location in the apparatus body 7 (substantially at the center of Figure 1B).
- the recording sheet 1 may be urled.
- a decurling shaft 43 is provided near that side of the roll holder 8 which is against to the platen roller 4.
- the decurling shaft 43 rotates in conformity with tension acting on the recording sheet 1, and is designed to cooperate with a guide shaft 24 which will be described later to eliminate the curl of the recording sheet 1.
- the present embodiment in order to achieve a reduction in the running cost, adopts the so-called multiprint system in which the recording sheet 1 and the ink sheet 2 are conveyed for recording with a velocity difference provided therebetween.
- recording is effected with the conveyed length of the ink sheet 2 being made shorter than the conveyed length L of the recording sheet 1 (L/n : n>1), and as compared with the conventional recording system in which the conveyed length of the recording sheet is made equal to the conveyed length of the ink sheet 2, the use efficiency of the ink sheet 2 is n times as high.
- the ink sheet 2 is constructed, for example, of four layers as shown in Figure 14 wherein an ink layer capable of transferring ink n times is provided on base film.
- the second layer is base film which provides a support for the ink sheet 2.
- the second layer may advantageously be aromatic polyamide film of high heat resisting property or condenser paper, but conventional polyester film will also stand use.
- the thickness of this layer may advantageously be as small as possible in respect of the quality of print from its role as a medium, and may desirably be 3 ⁇ m - 8 ⁇ m because the strength of the film must be taken into consideration.
- the third layer is an ink layer containing therein a quantity of ink which can be transferred n times to the recording sheet 1.
- the chief components of this layer are resin such as EVA as an adhesive agent, carbon black or nigrosine dye for coloring, and carnauba wax or paraffin wax as a binding material, and these components are combined so as to stand n times of use in the same portion.
- Sensitivity and density differ depending on the amount of application of this layer, which may desirably be about 4 g/m2 - 8 g/m2, although it can be chosen as desired.
- the fourth layer is a top coating layer which is not concerned in printing and which is for preventing the ink of the third layer from being pressure-transferred to the recording sheet 1, and is formed of transparent wax or the like. Thus, it is only the transparent fourth layer that is pressure-transferred, and the ground stain of the recording sheet 1 can be prevented.
- the first layer is a heat resisting coat layer for protecting the second layer, i.e., the base film, from the heat of the recording head 3 which is a thermal head.
- This heat resisting coat layer is suitable for multiprint in which heat energy for n lines may be applied to the same portion (when black information is continuous), but whether it should be used or not can be suitably chosen. Also, it is particularly effective for base film of relatively low heat resisting property such as polyester film.
- the construction of the ink sheet 2 is not limited to what has been described above, but may also be an ink sheet comprising, for example, a base layer and a porous ink retaining layer provided on one side of the base layer and containing ink therein, or an ink sheet comprising base film and a heat resisting ink layer of minute porous net-like structure provided on the base film, the ink layer containing ink therein.
- the material of the base film may be, for example, film of polyimide, polyethylene, polyester, polyvinyl chloride, triacetyl cellulose, nylon or the like, or paper.
- the heat resisting coat layer is not always necessary, but the material thereof may be, for example, silicon resin, epoxy resin, fluorine resin, etholocellulose or the like.
- the ink sheet 2 having heat-sublimated ink mention may be made of an ink sheet comprising a substrate formed of polyethylene terephthalate, polyethylene naphthalate, aromatic polyamide film or the like, and a color material layer provided thereon and formed of guanamine resin and fluorine resin and containing spacer particles and dyestuff.

- the rotational torque acting on the shaft portion 33c of the cover stay 33 becomes smaller than the rotational torque acting on the pivot shaft 10 of the recording cover 11 and accordingly, it is possible to make the rigidity of the torsion coil spring 36 small.
- the recording apparatus A of the present embodiment uses the heat transfer system.
- this recording system is such that the recording sheet 1 and the ink sheet 2 are made to overlap with each other and the ink sheet 2 is heated in the form of an image pattern from the support sheet thereof, whereby the ink is melted and transferred to the recording sheet 1 to thereby form an image thereon. Therefore, the adhering force of the melted ink acts between the recording sheet 1 and the ink layer.
- the conveying force acting on the recording sheet 1 is transmitted to the recording cover 11 by said adhering force through the ink sheet 2, and a force for moving the cover 11 in the direction of conveyance of the recording sheet 1 acts.
- the ink When image formation is being normally carried out, the ink is melted and therefore, the adhering force is small and poses no problem. However, if during image formation, the melted ink solidifies for some reason or other with the recording sheet 1 and the ink sheet 2 overlapping with each other, a great adhering force will be created, whereby the recording cover 11 may be moved in the direction of conveyance of the recording sheet 1.

- a line passing through the centers of the pair of U-grooves 38a is disposed parallel to the supply reel 25 and the take-up reel 26 for the ink sheet 2.
- the adhering force created between the recording sheet 1 and the ink layer is transmitted to the recording cover 11 through the ink sheet 2 and is further transmitted to the apparatus body 7 through the restraining members 38 and the shaft 37.
- the restraining members 38 and the shaft 37 fit together with a predetermined tolerance and thus, the recording cover 11 is not moved in the longitudinal direction.
- the ink cartridge 9 is mounted in the recording cover 11 as the loading portion and the cover 11 is closed, whereby the longitudinal positions and the vertical positions of the reels 25 and 26 can be set by bearing grooves 39a, 39b, 40a, 40b and a support member 42, and by a thrust being caused to act on the reels 25 and 26, the lateral positions of the reels 25 and 26 can be set.

Abstract
Description
- This invention relates to an ink sheet reel on which an ink sheet used in the heat transfer recording system can be wound, an ink sheet cartridge using said ink sheet reel, and a recording apparatus using these.
- The term "recording apparatus" covers, for example, a facsimile apparatus, a typewriter, a copying apparatus and a printer.
- Description will hereinafter be made with a facsimile apparatus taken as an example of the recording apparatus.
- In recent years, there has been developed a facsimile apparatus of the so-called heat transfer recording type which uses an ink sheet.
- The facsimile apparatus of this heat transfer recording type has the advantages that plain paper or the like can be used as a recording sheet and that images can be recorded clearly.
- In the facsimile apparatus of said heat transfer recording type, a supply reel for supplying an ink sheet and a take-up reel for taking up the ink sheet from the supply reel are loaded into a loading portion such as a recording cover, or the supply reel and the take-up reel as an ink sheet cartridge (hereinafter referred to as the ink cartridge) contained in a container are loaded into the loading portion such as the recording cover, and in order to enable this loading to be accomplished smoothly and easily, there is provided some gap axially of the reels between the supply reel or the take-up reel and the loading portion.
- However, in the conventional facsimile apparatus of the heat transfer recording type, spur gears are used as power transmission gears of the take-up reel and supply reel sides and power transmission gears of the conveying drive system side. Therefore, if a gap is provided between the supply reel or the take-up reel and the loading portion as previously described, the take-up reel and the supply reel may have lush in the axial direction, and this in turn leads to the disadvantage that oblique movement or skew or wrinkling of the ink sheet and unsatisfactory take-up of the ink sheet are caused.
- Also, to prevent the oblique movement or the like of the ink sheet caused by the jolting of said reels, axial pressure (side pressure) must be applied to the reels and for this purpose, spring means or the like becomes necessary, and this means an increased number of parts.
- It is an object of the present invention to provide an ink sheet reel capable of receiving a drive force more reliably, an ink sheet cartridge using such ink sheet reel, and a recording apparatus using these.
- It is another object of the present invention to provide an ink sheet reel capable of conveying an ink sheet without wrinkling the ink sheet, an ink sheet cartridge using such ink sheet reel, and a recording apparatus using these.
- It is still another object of the present invention to provide an ink sheet reel capable of being easily loaded, an ink sheet cartridge using such ink sheet reel, and a recording apparatus using these.
- It is yet still another object of the present invention to provide an ink sheet reel capable of being loaded with good accuracy, an ink sheet cartridge using such ink sheet reel, and a recording apparatus using these.
- It is a further object of the present invention to provide an ink sheet reel on which an ink sheet can be wound and which is made free of lush or jolting in the axial direction without the number of parts being increased, whereby oblique movement or the like of the ink sheet can be effectively prevented to thereby improve the quality of recording an ink sheet cartridge using such ink sheet reel, and a recording apparatus using these.
- It is still a further object of the present invention to facilitate the loading of a supply reel and a take-up reel for an ink sheet or of an ink cartridge cotaining the supply reel and the take-up reel in a container into a recording cover and yet eliminate the axial jolting of the ink sheet reel without increasing the number of parts.
- It is yet still a further object of the present invention to provide an ink sheet reel on which an ink sheet can be wound and which can thus effectively prevent oblique movement or the like of the ink sheet to thereby improve the quality of printing, an ink sheet cartridge using such ink sheet reel, and a recording apparatus using these.
- Typical means of the present invention for achieving these object is characterized by being constituted by an ink sheet winding portion on which an ink sheet can be wound, and power transmission means provided in said ink sheet winding portion and creating an axial thrust in said ink sheet winding portion.

- An ink sheet reel on which an ink sheet to which the means of the prevent invention is applied can be wound, an ink sheet cartridge using such ink sheet reel, and a recording apparatus using these will hereinafter be described with respect to a preferred embodiment thereof with reference to the drawings. The embodiment described hereinafter is designed such that when a rotational force is transmitted to a gear which is power transmission means, an axial thrust is produced in the ink sheet winding portion of an ink sheet reel and the ink sheet winding portion is pressed toward on axial end side by this thrust and in the loading portion of the recording apparatus side, this ink sheet winding portion is stopped. Also, at this time, it is desirable that the thrust of the ink sheet reel of the supply side and the thrust of the ink sheet reel of the take-up side act in the same direction.
- Thereby, even if an axial gap is present between the ink sheet reels and the loading portion therefore, the ink sheet reels may not jolt and oblique movement or the like of the ink sheet will not occur.
- Also, in the case of an ink cartridge in which ink sheet reels are contained within a frame member, said thrusts are stopped not by the frame member, but by the loading portion of the recording apparatus side and therefore, any stress based on the thrusts is not produced in the frame member and it is not necessary to endow the frame member itself with rigidity.
- The recording apparatus A according to the present embodiment is constructed as the recording system of a facsimile apparatus. Figure 1A is a pictorial perspective view of the facsimile apparatus, Figure 1B is a cross-sectional view of the facsimile apparatus, and Figures 2A and 2B are perspective views of the recording apparatus A.
- The general construction of the facsimile apparatus will first be briefly described with reference to Figures 1A and 1B and Figures 2A and 2B. Hereinafter, description will be made with the direction of arrow x in Figure 2A being defined as the lateral direction, the direction of arrow y being defined as the longitudinal direction, and the direction of arrow z being defined as the vertical direction.
- The facsimile apparatus is comprised of the recording apparatus A as the recording system, a reading system B for reading the image of an original, and an operation panel C.
- The recording apparatus A forms an image on a recording sheet 1 in comformity with an image signal transmitted from other apparatus or an image signal transmitted from the reading system B which will be described later.
- That is, the recording sheet 1 and an
ink sheet 2 overlapping with each other are urged against aplaten roller 4 by arecording head 3 as recording means, and by theplaten roller 4 being driven in the direction of arrow, the recording sheet 1 is conveyed in the direction of arrow a, and by adriving mechanism 44 which will be described later, theink sheet 2 is conveyed in the direction of arrow b. In the conveyance process of the recording sheet 1 and theink sheet 2, therecording head 3 is driven in conformity with an image signal, whereby ink applied to theink sheet 2 is melted (including sublimation) and the melted ink is transferred to the recording sheet 1 to thereby form an image. The recording sheet 1 on which a predetermined image has been formed is further conveyed in the direction of arrow a and is cut by a cutter 5, whereafter it is conveyed and discharged out of the recording apparatus A by a pair ofconveying rollers 6. - The recording sheet 1 is contained in a
roll holder 8 provided in theapparatus body 7. Theroll holder 8, theplaten roller 4, the cutter 5 and the pair ofconveying rollers 6 are provided in theapparatus body 7. - In the present embodiment, the
ink sheet 2 is inserted in anink cartridge 9 which will be described later. Theink cartridge 9 is removably loaded in arecording cover 11 as a loading portion pivotably constructed in theapparatus body 7 through apivot shaft 10. Therecording head 3 is provided at a predetermined location in therecording cover 11. - The reading system B applies a light to an original 12 and converts the reflected light therefrom into an electrical signal, and transmits this signal to other apparatus or the recording apparatus in conformity with the operation mode.
- That is, a plurality of
originals 12 are placed on an original supporting table 13 formed on top of therecording cover 11, and theseoriginals 12 are preliminarily conveyed by apreliminary conveying roller 14a and apressing roller 14b and are separated and fed one by one by a separatingroller 15a and apressing piece 15b urged thereagainst, and theoriginals 12 are conveyed by a pair of conveyingrollers discharge tray 17. A light is applied from alight source 18 to the surface of the original 12 while the original 12 is being conveyed, and the reflected light therefrom is caused to pass to aphotoelectric conversion element 21 such as a CCD via amirror 19 and alens 20, and the image signal thereof is transmitted to the reconding system of the recording apparatus in the case of the copy mode, and is transmitted to the recording system of other apparatus in the case of the transmission mode. - The operation panel C is a panel for performing operations such as the mode switching operation, and is provided with keys for the various operations. This operation panel C is provided on the upper portion of an original conveying mechanism in the recording system B, and is constructed for pivoted movement relative to the
apparatus body 7. One side of the operation panel C is equipped with a telephone set D for effecting transmission and reception. - In Figure 1B, the
reference numeral 22 designates an electric equipment substrate and thereference numeral 23 denotes a power source unit. - The recording sheet 1 may be plain paper, plastic film or a sheet of any other material to which ink is transferable. In the present embodiment, a long footage of plain paper of B4 width or A4 width is used as the recording sheet 1. A sheet roll 1a comprising the recording sheet 1 wound into the form of a roll is contained in the
roll holder 8 provided at a predetermined location in the apparatus body 7 (substantially at the center of Figure 1B). - The recording sheet 1 may be urled. In order to eliminate such curl, a
decurling shaft 43 is provided near that side of theroll holder 8 which is against to theplaten roller 4. Thedecurling shaft 43 rotates in conformity with tension acting on the recording sheet 1, and is designed to cooperate with aguide shaft 24 which will be described later to eliminate the curl of the recording sheet 1. - The present embodiment, in order to achieve a reduction in the running cost, adopts the so-called multiprint system in which the recording sheet 1 and the
ink sheet 2 are conveyed for recording with a velocity difference provided therebetween. - According to this multiprint system, recording is effected with the conveyed length of the
ink sheet 2 being made shorter than the conveyed length L of the recording sheet 1 (L/n : n>1), and as compared with the conventional recording system in which the conveyed length of the recording sheet is made equal to the conveyed length of theink sheet 2, the use efficiency of theink sheet 2 is n times as high. - Accordingly, in the present embodiment, the
ink sheet 2 is constructed, for example, of four layers as shown in Figure 14 wherein an ink layer capable of transferring ink n times is provided on base film. - That is, the second layer is base film which provides a support for the
ink sheet 2. In the case of multiprint, heat energy is applied to the same portion many times and therefore, the second layer may advantageously be aromatic polyamide film of high heat resisting property or condenser paper, but conventional polyester film will also stand use. The thickness of this layer may advantageously be as small as possible in respect of the quality of print from its role as a medium, and may desirably be 3 µm - 8 µm because the strength of the film must be taken into consideration. - The third layer is an ink layer containing therein a quantity of ink which can be transferred n times to the recording sheet 1. The chief components of this layer are resin such as EVA as an adhesive agent, carbon black or nigrosine dye for coloring, and carnauba wax or paraffin wax as a binding material, and these components are combined so as to stand n times of use in the same portion. Sensitivity and density differ depending on the amount of application of this layer, which may desirably be about 4 g/m² - 8 g/m², although it can be chosen as desired.
- The fourth layer is a top coating layer which is not concerned in printing and which is for preventing the ink of the third layer from being pressure-transferred to the recording sheet 1, and is formed of transparent wax or the like. Thus, it is only the transparent fourth layer that is pressure-transferred, and the ground stain of the recording sheet 1 can be prevented.
- The first layer is a heat resisting coat layer for protecting the second layer, i.e., the base film, from the heat of the
recording head 3 which is a thermal head. This heat resisting coat layer is suitable for multiprint in which heat energy for n lines may be applied to the same portion (when black information is continuous), but whether it should be used or not can be suitably chosen. Also, it is particularly effective for base film of relatively low heat resisting property such as polyester film. - The construction of the
ink sheet 2 is not limited to what has been described above, but may also be an ink sheet comprising, for example, a base layer and a porous ink retaining layer provided on one side of the base layer and containing ink therein, or an ink sheet comprising base film and a heat resisting ink layer of minute porous net-like structure provided on the base film, the ink layer containing ink therein. The material of the base film may be, for example, film of polyimide, polyethylene, polyester, polyvinyl chloride, triacetyl cellulose, nylon or the like, or paper. Further, the heat resisting coat layer is not always necessary, but the material thereof may be, for example, silicon resin, epoxy resin, fluorine resin, etholocellulose or the like. - Also, as an example of the
ink sheet 2 having heat-sublimated ink, mention may be made of an ink sheet comprising a substrate formed of polyethylene terephthalate, polyethylene naphthalate, aromatic polyamide film or the like, and a color material layer provided thereon and formed of guanamine resin and fluorine resin and containing spacer particles and dyestuff. - The constructions of an ink sheet reel, a cartridge having the ink sheet reel, and a recording apparatus using these will hereinafter be described.
- In the recording apparatus A, a
supply reel 25 and a take-up reel 26 constructed as will be described later are independently mounted in therecording cover 11 as the loading portion, and theink sheet 2 wound on thesupply reel 25 is taken up onto the take-up reel 26, whereby thesheet 2 can be conveyed to carry out image formation. - However, the
ink sheet 2 in the present embodiment is loaded and held in acartridge 9A (the cross-section of which is shown in Figure 6B) as the frame member of anink cartridge 9 constructed as shown in Figures 3 to 6A-6B. Figure 6A is an enlarged cross-sectional view of the central portion of thecartridge 9A of Figure 6B. - The
ink cartridge 9 is constructed with thesupply reel 25 and the take-up reel 26 being mounted at predetermined locations in thecartridge 9A as the frame member and with theink sheet 2 wound on the supply reel being extended onto the take-up reel 26 side to thereby load the cartridge with theink sheet 2. By using thisink cartridge 9, the loading of the recording apparatus A with theink sheet 2 can be very easily and reliably accomplished in a stable state. - The
cartridge 9A in the present embodiment is molded as a unit of plastic, whereby the number of parts and the assembling cost are reduced. - As shown, the
cartridge 9A has afirst housing 9a, asecond housing 9b anddoors - That is, as shown in Figure 6 which is a cross-sectional view of the
cartridge 9A, a thin-walled portion 9e formed with a thickness smaller than the thickness of thefirst housing 9a and thesecond housing 9b is provided in the connecting portion between the twohousings walled portions first housing 9a and thedoors housing 9a. Thedoors piece 9h. - The thin-
walled portion 9e is constructed so as to serve as a hinge when thefirst housing 9a and thesecond housing 9b are closed in opposed relationship with each other after thesupply reel 25 and the take-up reel 26 are inserted into thecartridge 9A. Also, the thin-walled portions doors fork members 3c provided on both sides of therecording head 3 shown in Figure 2 when theink cartridge 9 has been mounted in the recording apparatus A. - The thin-
walled portions 9e-9g have flexibility and moderate strength. That is, the thicknesses of the thin-walled portions 9e-9g are set to appropriate dimensions in conformity with the plastic material used. - The thin-
walled portions 9e-9g may be formed over the full length and may be intermittently formed with predetermined lengths. - The moustache-like connecting
piece 9h (see Figures 3 and 4) connecting thedoors doors ink cartridge 9 when thecartridge 9 is not used. Also, theform members 3c provided on therecording head 3 are formed with such dimensions that when loading the recording apparatus A with theink cartridge 9, thefork members 3c bear against thedoors doors - The molding material of the
cartridge 9A may be resin such as polypropylene resin or ABS resin. - In the
cartridge 9A, awindow 9i, for inserting theplaten roller 4 therethrough is formed substantially centrally of thesecond housing 9b and a cut-away 9i₂ for permitting theshaft portion 4b of theplaten roller 4 to escape is formed continuously to the window 9i₁. - Side plates 9a₁ and 9b₁ are formed upright on both sides of the
first housing 9a and thesecond housing 9b, and the portions thereof which are adjacent to the thin-walled portion 9e and the open side are formed with curved surfaces of square circle. Also, in the open side curved surface, engagement recesses 9a₂ are formed on thefirst housing 9a side, and restraining projections 9b₂ for engagement with the engagement recesses 9a₂ are formed on thesecond housing 9b side. Further, in the open side curved surfaces of thefirst housing 9a and thesecond housing 9b, there are formed restraining projections 9a₃ and 9b₃ adapted to be engaged with a restrainingspring 41 provided on therecording cover 11 when theink cartridge 9 is mounted in therecording cover 11. - At predetermined locations on the side plates 9b₁ of the
second housing 9b, there are formedguide pins 9j which provide guides when theink cartridge 9 is mounted in therecording cover 11. - At predetermined locations on the side plates 9a₁ and 9b₁, there are formed u-grooves 9k for loosely fitting therein
bearings 27 mounted on thesupply reel 25 and u-grooves 9ℓ for loosely fitting thereinbearings 27 mounted on the take-up reel 26. Also, thefirst housing 9a and thesecond housing 9b are formed withopenings 9m through which thereel gear 25c of thesupply reel 25 and thereel gear 26c of the take-up reel 26 may be exposed. - In Figure 4, the
reference character 9n designates an identifying portion adapted to contact with a sensor 50 provided in therecording cover 11 when theink cartridge 9 is mounted in therecording cover 11, and identify the presence or absence of theink cartridge 9 or the size or the like of theink sheet 2 loaded in theink cartridge 9, by the sensor 50. - The
supply reel 25 and the take-up reel 26, as shown in Figure 3, havereel shafts 25a and 26a, respectively, having a longer dimension than the width dimension of theink cartridge 9. Flanges 25b₁, 25b₂, 26b₁ and 26b₂ each having a length substantially equal to the internal dimension of theink cartridge 9 are provided on the reel shafts 25a and 25b. Reel gears 25c and 26c as means for transmitting the motive power are integrally formed on the flanges 25b₁ and 26b₁, respectively. - In the present embodiment, the reel gears 25c and 26c are helical gears, and the torsional direction of the teeth of these reel gears
25c ard 26c is the direction from the flanges 25b, 26b, toward the flanges 25b₂, 26b₂, i.e., the direction in which a trust can be created in thereel shafts 25a and 26a at one axial end thereof. - Also, the opposite ends of the
reel shafts 25a and 26a are constructed so as to protrude outwardly of the reel gears 25c, 26c, and the flanges 25b₂, 26b₂. Thebearings 27 are rotatably mounted on these protruding ends. Accordingly, thereels grooves 9k and 9ℓ through thebearings 27 when thereels cartridge 9A of theink cartridge 9. Thebearings 27 protrude from thecartridge 9A of theink cartridge 9 and are fitted into bearinggrooves apparatus body 7 of the recording apparatus A. - Description will now be made of a case where the
ink sheet 2 is inserted into thecartridge 9A constructed as described above to thereby manufacture theink cartridge 9. - With the
cartridge 9A opened as shown in Figure 3, thesupply reel 25 having theink sheet 2 thereon and having thebearings 27 mounted on the opposite ends thereof is mounted in the U-grooves 9k of thesecond housing 9b. Also, the take-up reel 26 having thebearings 27 mounted on the opposite end thereof is mounted in the U-grooves 9ℓ. Then, the leading end of theink sheet 2 is drawn out from thesupply reel 25 and is attached to thereel shaft 26a of the take-up reel 26 as by an adhesive tape. Thereafter, thefirst housing 9a is bent about the thin-walled portion 9e and opposed to the second housing, and the engagement projections 9b₂ are brought into engagement with the engagement recesses 9a₂, whereby theink cartridge 9 loaded with theink sheet 2 as shown in Figures 4 and 5 can be manufactured. - The
ink cartridge 9 is mounted in therecording cover 11 through a mountinggroove 28 constructed as will be described later. - A recording unit is constituted by the
recording head 3 and theplaten roller 4. Therecording head 3 and theplaten roller 4 are disposed in opposed relationship with each other. Therecording head 3 is pivotably provided in therecording cover 11, and theplaten roller 4 is rotatably provided in theapparatus body 7. - In the case of the present embodiment, the
recording head 3 is a thermal head having a plurality of heat generating elements, and is pivotably mounted on a head supporting portion 3a provided in therecording cover 11. Also, therecording head 3 is biased toward theplaten roller 4 by aspring 3b disposed between thehead 3 and therecording cover 11. By this biasing force, therecording sheet 11 and theink sheet 2 overlapping with each other are urged against theplaten roller 4. -
Fork members 3c are provided on both sides of therecording head 3. Thesefork members 3c open thedoors ink cartridge 9 when thecartridge 9 is mounted in therecording cover 11, and have the positioning function for engaging theshaft portion 4b of theplaten roller 4 and thereby setting the position of therecording head 3 relative to theplaten roller 4. - The
platen roller 4 is provided downstream with respect to the direction of conveyance of the recording sheet 1, as shown in Figure 1B. Theplaten roller 4 is formed with aroller portion 4a conforming to the width dimension of the recording sheet 1 (see Figures 2A and 2B).Shaft portions 4b are formed at the opposite ends of theroller portion 4a, and thefork members 3c provided on therecording head 3 are engageable with theshaft portions 4b. - The
platen roller 4 is driven by the drive force of amotor 29. Themotor 29 is secured to aside plate 7a of theapparatus body 7. The rotation of themotor 29 is transmitted to theplaten roller 4 through power transmission gears 30a-30c. When carrying out image formation on the recording sheet 1, theplaten roller 4 is rotated in the direction of arrow as shown in Figure 1B to thereby convey the recording sheet 1 in the direction of arrow a, and after the recording sheet 1 is cut by the cutter 5, theplaten roller 4 is rotated in the direction opposite to the direction of arrow to thereby convey the recording sheet 1 in the direction opposite to the direction of arrow a. - The
apparatus body 7 in which theplaten roller 4, etc. are provided is formed into a lateral U-shape having rigidity as shown in Figure 2. Theapparatus body 7 is formed withside plates side plates partition plate 7c. Thepartition plate 7c has the function of spacing the recording apparatus A and the reading system B apart from each other. - The recording cover is openably and closably mounted on the
apparatus body 7 through apivot shaft 10. - In the present embodiment, the pivot axis of the
recording cover 11 relative to theapparatus body 7 is positioned at the end thereof which is adjacent to the original supporting table 13 formed on top of therecording cover 11 and which is sideways of the operation panel C. - That is, as shown in Figures 7 to 9A and 9B, the
recording cover 11 has its upper surface constructed as the original supporting table 13, which is formed with aninclined portion 13a downwardly inclined toward the reading system B. It is also constructed so that thehorizontal portion 13b of the original supporting table 13 may be substantially flush with the upper surface of the operation panel C. - At the end of the
recording cover 11 which is adjacent to the reading system B, i.e., the end of theinclined portion 13a of the original supporting table 13 as shown in Figures 7 and 8, there is provided ashaft member 31 havingpivot shafts 10 on the opposite sides thereof. Thisshaft member 31 is constructed so as to protrude to that side of therecording cover 11 which is adjacent to the original supporting table 13 and to position thepivot shafts 10 sideways of the operation panel C. Theinclined portion 13a is provided with aslider 13c for guiding the original 12, theslider 13c being slidable in accordance with the size of the original 12. - A pair of
opposed brackets 32 are secured to the ends of theside plates apparatus body 7 which are adjacent to thepartition plate 7c. Thesebrackets 32 provide a support portion for pivotably supporting therecording cover 11 relative to theapparatus body 7. For this purpose, as shown in Figure 9, eachbracket 32 is formed with apivot hole 10a for inserting thereinto apivot shaft 10 provided on therecording cover 11. Thepivot hole 10a may be a round hole, but in the present embodiment, it is in the form of a slot in which the recording cover is longitudinally movable relative to theapparatus body 7. - The
brackets 32, as shown in Figures 7 and 8, are constructed so as to position thepivot holes 10a formed therein at the sideways end of the operation panel C which is adjacent to the original supporting table 13. That is, they are constructed so as to position the pivot axis of therecording cover 11 at the sideways end of the operation panel C which is adjacent to the original supporting table 13. - By fitting the
pivot shaft 10 of therecording cover 11 into thepivot holes 10a formed in thebrackets 32, it becomes possible to openably and closably mount therecording cover 11 on theapparatus body 7, thereby positioning the pivot axis of therecording cover 11 at the sideways end of the operation panel C which is adjacent to the original supporting table 13. - By the pivot axis of the
recording cover 11 relative to theapparatus body 7 being positioned at the sideways end of the operation panel C which is adjacent to the original supporting table 13 as described above, the end portion of the operation panel C and the end portion of the original supporting table 13 do not interfere with each other when therecording cover 11 is opened. Therefore, it becomes possible to dispose the operation panel C closely adjacent to the original supporting table 13 and accordingly, it becomes possible to made the full length of the apparatus short. - When the
recording cover 11 is closed, a weight acting on the center of gravity of the recording, cover 11 and a rotational torque conforming to the horizongal distance from thepivot shaft 10 to the center of gravity act on thepivot shaft 10. Accordingly, when therecording cover 11 is caused to fall freely from its open position, a shock may be created by the action of said rotational torque when thecover 11 is closed. - So, in the present embodiment, a
torsion coil spring 36 is mounted on ashaft portion 33c provided on acover stay 33 for maintaining the open position of therecording cover 11 so that a braking force may be created by thespring 36. - That is, as shown in Figures 10 and 11A and 11b, the
cover stay 33 is pivotably mounted on theside plate 7b of theapparatus body 7 and apin 34 is provided on therecording cover 11. - The cover stay 33 is mounted on a mounting
portion 35 provided on theside plate 7b. The location of the mountingportion 35 is closer to the center of gravity G of therecording cover 11 than to thepivot shaft 10 which is the pivot axis of therecording cover 11 relative to theapparatus body 7. Thepin 34 is provided near the center of gravity of therecording cover 11. - The cover stay 33 is constituted by a
plate member 33b formed with agroove 33a and ashaft portion 33c for mounting thetorsion coil spring 36 thereon. Thegroove 33a is such that an arcuate groove 33a₁ is formed near theshaft portion 33c and a substantially straight groove 33a₂ is formed continuously to the arcuate groove 33a₁. Thepin 34 provided on therecording cover 11 is fitted in thegoove 33a, and the rotational force of therecording cover 11 is transmitted to the cover stay 33 through thepin 34. A projection 33a₃ formed at one end of the groove 33a₂ is for engaging thepin 34 to thereby maintain the open position of therecording cover 11. - A through-
hole 33d is formed axially through theshaft member 33c. By the cover stay 33 being fitted to ashaft 35a provided in the mounting portion through the through-hole 33d, thestay 33 is mounted on theapparatus body 7 for pivotal movement about theshaft 35a. - The
torsion coil spring 36 is mounted around theshaft member 33c. Onearm 36a of thetorsion coil spring 36 is inserted in agroove 35b formed in the mountingportion 35 and is fixed to theapparatus body 7, and theother arm 36b is a free end. Thetorsion coil spring 36 is mounted on theshaft member 33c in such a manner that it is freely tightened when the cover stay 33 pivots in a direction to close therecording cover 11 and it is freely loosened when the cover stay 33 pivots in a direction to open therecording cover 11. The inner diameter of thetorsion coil spring 36 is made substantially equal to or slightly smaller than the outer diameter of theshaft member 33c. Accordingly, a frictional load is always acting between thetorsion coil spring 36 and theshaft member 33c. - By the
pin 34 provided on therecording cover 11 being fitted in thegroove 33a in the cover stay 33 constructed as described above, it is possible to create a braking force by thetorsion coil spring 36 when therecording cover 11 is closed. - That is, while shift is made from the open position of the
recording cover 11 shown in Figure 8 to the closed position of therecording cover 11 shown in Figure 7 (that is, while therecording cover 11 is shifted by uniform angular velocity motion from its open position to its closed position), thepin 34 comes into engagement with the groove 33a₂ in the cover stay 33 as shown in Figure 11A. At this time, with the pivotal movement of therecording cover 11, thecover stay 33 rotates, but this angle of rotation is not great because the groove 33a₂ is straight. When the pivotal movement of therecording cover 11 progresses and thepin 34 comes into engagement with the arcuate groove 33a₁ as shown in Figure 11b, the angle of rotation of thecover stay 33 becomes greater. Accordingly, the frictional load between thetorsion coil spring 36 and theshaft member 33c becomes greater and thespring 36 is freely tightened, whereby a braking force acts on thecover stay 33. At this time, the rotational torque acting on theshaft portion 33c of thecover stay 33 becomes smaller than the rotational torque acting on thepivot shaft 10 of therecording cover 11 and accordingly, it is possible to make the rigidity of thetorsion coil spring 36 small. - The recording apparatus A of the present embodiment uses the heat transfer system. As previously described, this recording system is such that the recording sheet 1 and the
ink sheet 2 are made to overlap with each other and theink sheet 2 is heated in the form of an image pattern from the support sheet thereof, whereby the ink is melted and transferred to the recording sheet 1 to thereby form an image thereon. Therefore, the adhering force of the melted ink acts between the recording sheet 1 and the ink layer. The conveying force acting on the recording sheet 1 is transmitted to therecording cover 11 by said adhering force through theink sheet 2, and a force for moving thecover 11 in the direction of conveyance of the recording sheet 1 acts. - When image formation is being normally carried out, the ink is melted and therefore, the adhering force is small and poses no problem. However, if during image formation, the melted ink solidifies for some reason or other with the recording sheet 1 and the
ink sheet 2 overlapping with each other, a great adhering force will be created, whereby therecording cover 11 may be moved in the direction of conveyance of the recording sheet 1. - Therefore, in the present embodiment, the
recording cover 11 is fixed to theapparatus body 7 so that therecording cover 11 may not be moved in the longitudinal direction. - That is, as shown in Figures 7 and 8, a
shaft 37 is provided on theside plates apparatus body 7 downstream with respect to the direction of conveyance of the recording sheet 1. Thisshaft 37 is disposed with a predetermined degree of parallelism relative to the axial direction of theplaten roller 4. - On the opposite sides of the
recording cover 11, a pair of restrainingmember 38 are secured at a location opposed to theshaft 37. Each of these restrainingmembers 38 is formed into a fork-like shape having a U-groove 38a engaged by theshaft 37. The inner diametrical dimension of the U-groove 38 is designed with a predetermined tolerance of engagement relative to the outer diametrical dimension of theshaft 37. A line passing through the centers of the pair of U-grooves 38a is disposed parallel to thesupply reel 25 and the take-up reel 26 for theink sheet 2. By bringing the restrainingmembers 38 into engagement with theshaft 37 when therecording cover 11 is closed relative to theapparatus body 7, therecording cover 11 is accurately positioned relative to theapparatus body 7 and the movement of thiscover 11 in the longitudinal direction is prevented. - In the above-described construction, the adhering force created between the recording sheet 1 and the ink layer is transmitted to the
recording cover 11 through theink sheet 2 and is further transmitted to theapparatus body 7 through the restrainingmembers 38 and theshaft 37. At this time, the restrainingmembers 38 and theshaft 37 fit together with a predetermined tolerance and thus, therecording cover 11 is not moved in the longitudinal direction. - Description will now be made of the construction of the loading portion of the
recording cover 11 which is removably loaded with theink cartridge 9 and the construction of the gear portion of the conveying system for conveying theink sheet 2 in theink cartridge 9. - In the present embodiment, the
ink cartridge 9 is mounted in therecording cover 11 as the loading portion and thecover 11 is closed, whereby the longitudinal positions and the vertical positions of thereels grooves support member 42, and by a thrust being caused to act on thereels reels - The construction of the portion which is loaded with the
ink cartridge 9 will first be described specifically. A mountinggroove 28 for removably loading the loading portion with theink cartridge 9 is provided in opposed relationship with both sides of therecording cover 11, as shown in Figure 2. This mountinggroove 28 is formed by a hook-shaped groove to restrain theguide pin 9j of theink cartridge 9. On both sides of therecording cover 11,U-shaped bearing grooves bearings 27 fitted to the opposite ends of thereels bearings 27 are opposedly provided on the same extension at a predetermined interval. The bearinggrooves recording cover 11, and the bearinggrooves spring 41 for restraining the restraining projection 9b₃ of theink cartridge 9 is provided near the open end side of therecording cover 11. -
Support members 42 are provided on theside plates apparatus body 7 which are opposed to thebearing grooves recording cover 11. Thesupport members 42 bear against thebearings 27 fitted to the opposite ends of thereels bearings 27 toward the bearinggrooves reels recording cover 11. Each of thesupport members 42 is comprised of a case 42a secured to theside plate support piece 42b having one end thereof contained in the case 42a and the other end having a contact surface with respect to thebearing 27, and a spring contained in the case 42a. - Accordingly, the
guide pin 9j of theink cartridge 9 is fitted in and restrained by the hook-shaped groove 28a, theink cartridge 9 is rotated about theguide pin 9j and the restraining projection 9b₃ is restrained by the restrainingspring 41, whereby theink cartridge 9 is mounted in therecording cover 11. At this time, thebearings 27 fit in therespective bearing grooves recording cover 11 is closed, thebearings 27 are supported by thesupport pieces 42b of thesupport members 42 and are biased toward the bearinggrooves reels recording cover 11 set. - Also, when the
ink cartridge 9 is to be mounted in therecording cover 11 as previously described, it is possible to cause thecartridge 9 to bear against theguide shaft 24 rotatably provided in therecording cover 11 as shown in Figure 1, and insert the cartridge along thisguide shaft 24. Also, when theguide pin 9j of theink cartridge 9 is fitted into the mountinggroove 28 shown in Figure 2 and thereafter theink cartridge 9 is rotated, thefork members 3c provided on both sides of therecording head 3 bear against thedoors ink cartridge 9 and break away and open the moustache-like connectingpiece 9h connecting thedoors recording head 3 is inserted into theink cartridge 9. - When the
ink cartridge 9 is mounted in therecording cover 11 in the manner describe:d previously, the longitudinal positions of thereels grooves recording cover 11 is closed relative to theapparatus body 7, the vertical positions of thereels grooves support members 42. - Also, when the
ink cartridge 9 is mounted in therecording cover 11, the sensor 50 provided in thecover 11 bears against the identifyingportion 9n of theink cartridge 9 so as to be able to detect tle presence or absence of theink cartridge 9 or the size or the like of theink sheet 2 inserted in theink cartridge 9. - Description will now be made of the gear portion as the power transmitting means of the conveying system for the
ink sheet 2. - When the
ink cartridge 9 is mounted in therecording cover 11, thereel gear 26c of the take-up reel 26 may come into meshing engagement with a driveforce transmitting gear 44a (see Figure 13) constituting adriving mechanism 44 for the take-up reel 26 provided in therecording cover 11 and thereel gear 25c of thesupply reel 25 may come into meshing engagement with atension transmitting gear 45a constituting a backtension imparting mechanism 45 provided in theapparatus body 7 as shown in Figure 2. - The reel gears 25c and 26c of the
reels force transmitting gear 44a andtension transmitting gear 45a on therecording cover 11 side which mesh with the reel gears 25c and 26c are likewise constructed of helical gears. - As shown in Figure 12, the
reel gear 26c of the take-up reel 26 and the driveforce transmitting gear 44a on therecording cover 11 side are brought into meshing engagement with each other to cause a rotational force to act on the driveforce transmitting gear 44a, thereby creating an axial thrust in the take-up reel 26. - Also, the
reel gear 25c of thesupply reel 25 and thetension transmitting gear 45a on therecording cover 11 side are brought into meshing engagement with each other. When theink sheet 2 wound on thesupply reel 25 is taken up by the take-up reel 26, thesupply reel 25 is rotated by the tension acting on theink sheet 2. When said rotational force acts from thereel gear 25c onto thetension transmitting gear 45a on therecording cover 11 side, thereel gear 25c creates an axial thrust in thesupply reel 25. The helical gears 25c and 26c are installed so that at this time, the thrusts of theink sheet reel 25 on the supply side and theink sheet reel 26 on the take-up side may act in the same direction. - Accordingly, the thrusts acting on the
reels bearings 27 fitted in the bearinggrooves recording cover 11. Said thrusts are then transmitted from thebearings 27 to therecording cover 11 and after all, thereels cover 11 in a state in which they are positioned at the side end in the same direction. - In the
supply reel 25 and take-up reel 26 constructed as described above, an axial thrust acts during the conveyance of theink sheet 2. Therefore, thereels grooves recording cover 11. Accordingly, thereels ink sheet 2, whereby oblique movement of theink sheet 2 is prevented and there is no possibility of jam being caused by the oblique movement. Also, the thrusts of thereels grooves ink cartridge 9 and therefore, it is not necessary to endow theink cartridge 9 with rigidity. - If in the reel gears 25c, 26c, the drive
force transmitting gear 44a and thetension transmitting gear 45a which are constructed of helical gears as described above, the torsion angle of the helical gears is smaller than 3°, axial thrust will not be sufficiently obtained, and if the torsion angle is greater than 20°, axial thrust will become great but will hinder the rotation of the gears, and therefore the torsion angle is set to the range of 3° to 30°, and may preferably be set to the range of 4°-15°, and may most preferably be set to the range of 5°-10°. - Also, in the present embodiment, it is preferable that the number of teeth of each of the reel gears 25c and 26c be set to e.g. 52 and the number of teeth of each of the drive
force transmitting gear 44a and thetension transmitting gear 45a be set to e.g. 12. If the numbers of teeth of thegears - In the present embodiment, the multiprint system is adopted as the recording apparatus A, but in the case of such recording system, images are formed while the ink is sheared in the ink layer and therefore, to convey the
ink sheet 2, there becomes necessary the frictional force between theink sheet 2 and therecording head 3, plus the shearing force for the ink. For this reason, the conveying force for theink sheet 2 need be greater than the conveying force when the conventional one-time ink sheet is used. - Also, in the multiprint system, it is necessary that the
ink sheet 2 be reliably conveyed by 1/n lines each time images for one line are formed on the recording sheet 1, and it becomes possible to enhance the quality of recorded images by ensuring said conveyance to be effected reliably. - In order to satisfy such a condition, in the present embodiment, a
driving mechanism 44 for the take-up reel 26 for conveying theink sheet 2 is provided on a side of therecording cover 11, as shown in Figure 2B. Thedriving mechanism 44 is constructed as shown in Figure 13. - The
driving mechanism 44 is such that abracket 46 is secured to a side (in the present embodiment, the right side) of therecording cover 11 and adrive motor 44b is secured to thebracket 46. Amotor gear 44c is mounted on the shaft of thedrive motor 44b. Afirst reduction gear 44d, asecond reduction gear 44e and athird reduction gear 44f which is formed integrally with the driveforce transmitting gear 44a are rotatably mounted on thebracket 46 with a predetermined distance maintained between the shafts of the adjacent gears. Accordingly, the rotation of thedrive motor 44b is reliably transmitted to the driveforce transmitting gear 44a while being decelerated through thegears 44c to 44d-44f. - As described above, in the
driving mechanism 44 in the present embodiment, it is possible that the rotation of thedrive motor 44b is reliably transmitted to the driveforce transmitting gear 44a and accordingly, it becomes possible to reliably convey theink sheet 2 at a predetermined conveyance velocity. - In the present embodiment, as previously described, the restraining
member 38 is provided in therecording cover 11 and theshaft 37 engageable with the restrainingmember 38 is provided in theapparatus body 7, and by closing therecording cover 11, the restrainingmember 38 is engaged with theshaft 37, thereby preventing the movement of therecording cover 11 in the longitudinal direction. - Description will now be made of a back
tension imparting mechanism 45 for imparting back tension to the take-up reel 26. The backtension imparting mechanism 45, as shown in Figures 2A and 2B, is provided on theside plate 7a of theapparatus body 7. - The back
tension imparting mechanism 45 is comprised of a pivotable plate 45b₂ constructed on theside plate 7a for pivotal movement about a pivot fucrum 45b₁, a slide clutch 45c secured to the pivotable plate 45b₂ and connected to thetension transmitting gear 45a, and atension spring 45 for upwardly biasing the pivotable plate 45b₂. - In the back
tension imparting mechansim 45 constructed as described above, when thereel gear 25c of thesupply reel 25 comes into meshing engagement with thetension transmitting gear 45a and theink sheet 2 wound on thereel 25 is rewound, thereel 25 is rotated. The rotation of thesupply reel 25 is transmitted from thereel gear 25c to the slide clutch 45c through thetension transmitting gear 45a. Thereby, predetermined back tension is imparted to theink sheet 2. - Description will now be made of image formation in the recording apparatus A constructed as described above.
- First, the
recording cover 11 is opened as shown in Figure 8 and the sheet roll 1a is contained into theroll holder 8, and then the leading end of the recording sheet 1 is drawn out to theplaten roller 4. Then, theink cartridge 9 is mounted in therecording cover 11 in the manner described previously, whereby theink sheet 2 is loaded and thecover 11 is closed. By therecording cover 11 being thus closed, thesupply reel 25 and the take-up reel 26 mounted in theink cartridge 9 are fitted into the bearinggrooves reels member 38 provided on therecording cover 11 comes into engagement with theshaft 37 provided in the apparatus body, whereby therecording cover 11 is set at a predetermined position relative to theapparatus body 7 and is restricted in its longitudinal movement. - Where an original 12 is placed on the original supporting table 13 formed on top of the
recording cover 11 and the copying mode is selected in the operation panel C, the original 12 is read in the reading system B and at the same time, an image signal is transmitted to the recording apparatus A. At the same time, theplaten 4 is driven by themotor 29 to convey the recording sheet 1 in the direction of arrow a and theink sheet 2 is conveyed in the direction of arrow b by thedrive motor 44b. Therecording head 3 is driven in response to the transmitted image signal, whereby an image is formed on the recording sheet 1. The recording sheet 1 on which a predetermined image has been formed is further conveyed in the direction of arrow a and, when the end portion of the image comes to the cutter 5, the cutter 5 is driven to cut the recording sheet 1. The cut recording sheet is conveyed and discharged out of the apparatus by the pair of conveyingrollers 6. Also, the recording sheet 1 is conveyed in the direction opposite to the direction of arrow a by theplaten roller 4. - In the manner described above, a predetermined image can be formed on the recording sheet 1.
- The aforedescribed embodiment has been shown with respect to a case where the numbers of teeth of the drive
force transmitting gear 44a and thetension transmitting gear 45a are the same, but gears having different numbers of teeth may also be used. By freely choosing the numbers of teeth of the drive force transmitting gear and the tension transmitting gear, the conveyance velocity of the ink sheet by the drive force transmitting gear and the tension to the ink sheet by the tension transmitting gear and the back tension imparting mechanism can be selected independently of each other. If in the present embodiment, the numbers of teeth of the helical gears are chosen to 50 to 54, the number of teeth of the driveforce transmitting gear 44a may be set to 14-20, preferably 16-18. The number of teeth of thetension transmitting gear 45a may be set to 15-21, preferably 17-19. - If the numbers of teeth of the helical gears and the transmitting gears are so set, the torsion angle of the helical gears may be set to the range of 3° to 30° with the thrust created by the helical gears being taken into account, and may preferably be set to the range of 5° to 20°, and may most preferably be set to the range of 10° to 16°.
- Also, in the aforedescribed embodiment, an application of the present invention to the
ink cartridge 9 has been shown, but of course, the present invention is also applicable to a case where the recording apparatus is loaded with ink sheet reels (thesupply reel 25 and the take-up reel 26) which are not contained in thecartridge 9A. - Also, the multiprint system has been shown as being adopted as the heat transfer recording system, but the present invention is euqally applicable to a recording apparatus of the type in which ink is completely transferred to the recording sheet 1 by one time image recording.
- The helical gears mentioned herein refer to a gear in which the tooth face is helical and the pitch surface is a cylindrical surface and a gear which has a thread or multiple threads and is of a similar shape. The tooth face may be straight or curved relative to the cylindrical surface, or some of tooth faces may be opposite in direction on the cylindrical surface. In short, any gear which can create axial thrust is covered by the term "helical gears" used herein.
- So, in the aforedescribed embodin,ent, there has been shown a case where helical gears (the reel gears 25c and 26c) are used as gear means for creating an axial thrust, whereas this is not restrictive, but an axial thrust can also be created, for example by the use of level gears or the like, and it is to be understood that these gears are also covered by the term "helical gears" used herein.
- Also, there has been shown a case where the
recording cover 11 side is loaded with the ink cartridge 9 (thesupply reel 25 and the take-up reel 26), but theapparatus body 7 side may also be loaded with the ink cartridge. - The
ink cartridge 9 has been shown as having been molded as a unit by the use of plastic, but alternatively, thefirst housing 9a, thesecond housing 9b, etc. may be formed as discrete parts. - Also, there has been shown a case where the
cartridge 9A which is the frame member of theink cartridge 9 is constructed so as to cover theink sheet 2 substantially completely, except the portion in which therecording head 3, etc. are inserted, but alternatively, use may be made of a cartridge comprising a framework portion large enough to hold the ink sheet reels (thesupply reel 25 and the take-up reel 26). - In the aforedescribed embodiment, an ink sheet retaining ink therein from first is us<.d as the
ink sheet 2, but of course, use may also be made of a sheet which does not retain ink therein when it is wound on the supply reel, but is made to retain ink therein after it is fed from the supply reel. In such case, the sheet-like member wound on the supply reel may be any one capable of retaining ink therein, such as an ink sheet of the material as mentioned previously having minute porous net-like structure on the base film thereof. - The present invention, as described previously, is provided with an ink sheet winding portion on which an ink sheet can be wound, and power transmitting means provided in this ink sheet winding portion for creating an axial thrust in the ink sheet winding portion and therefore, can eliminate axial jolting without the necessity of providing spring means as in the prior art, thereby effectively preventing oblique movement or the like of the ink sheet and improving the quality of printing, as well as reducing the number of parts and achieving a reduction in cost.
- Also, where design is made such that said axial thrust is received by the loading portion of the recording apparatus, it is not required to endow the frame member itself of the ink cartridge containing the ink sheet reels in the frame member with rigidity, and this also leads to the possibility of reducing the cost.
- An ink sheet reel capable of being loaded into a recording apparatus has an ink sheet winding portion on which an ink sheet can be wound, and power transmission means provided so as to create an axial thrust in the ink sheet winding portion.
