Definitions
- a recording apparatusof the non-impact type comprises a thermal head having a plurality of islands generally disposed in a common plane which are thermally independent and can heat separately and selectively.
- the apparatus employs a print member composed of a heat-resistant back-up layer and a thin film of an adhesive resin of low melting point disposed over the back-up layer, and also employsa web of recording paper free of any thermosensitive material. When the thermal head and the recording paper are moved relative to each other in one direction, the print member is brought into intimate contact with both of the thermal head and the recording paper.
- the islands in the thermal head may be selectively energized to melt the adhesive resin therein and transfer the molten resin to the recording paper, thus accomplishing a print on the recording paper.
- the thermal head may be an assembly of plural thermal heads arrayed in a row so as to define a print line.
- FIG 35 SQ-I 59-2 59-3 RECORDING APPARATUS BACKGROUND OF THE INVENTION 1.
- Field of the Invention 1 This invention relates to a recording apparatus of the non impact type which uses a thermal head and a print member to record information on a web of recording pattern. After one character has been printed, the thermal elementmay be moved to a position for printing the next information, thus accomplishing a series of desired prints on the thermosensitive paper.
- thermosensitive paper is the only usable recording medium in this system and this means a much higher running cost as well as very much limited choice of available recording mediums.
- thermosensitive paper even once printed, is ready to be thereby impress the recording medium with the shapes of the printing types or the pins. Such system is commonly referred to as impact printer.
- the non-impact printers aregrouped into various types'such as the ink jet system whereby drops of ink are moved through theair in a controlled direction so as to adhere to recording paper to thereby depict any desired information on the recording paper, the thermal print system whereby 'e iothermic elements adjacent a sheet of thermosensitive provide any desired pattern on the thermosensitive paper, and the discharge print system whereby a discharge wire scans over a sheet of discharge breakdown paper with a discharge signal being applied between the discharge paper and the'discharge wire to thereby break down portions of the discharge paper which display the desired information.
- the thermal print system has been most popular inasmuch as it involves less of the mechanical drive portions and permits easier application of electrical controls.
- Such a thermal printer uses print elements which may be formed of semiconductor material, as shown in U.S. Pat. No. 3,496,333.
- print element comprises a semiconductor substrate formed with a plurality of thermally independent islands, each of which is provided with a semiconductor heating section. Any one of these islands may be selected to represent the information to be printed and a heating current may be applied to the selected island to cause the associated heating section to heat in the pattern of the information to be printed.
- the described thermal element may be disposed on a sheet of thermosensitive paper which maybe discolored in the portions thereof subjected to heat, and then the thermal element may be energized so that the se paper are selectively caused to generate heat to thereby v discolored by any extraneous heat applied thereto, and this leads to a serious problem in keeping the printed paper.
- SUMMARY OF THE INVENTION 1 may be contacted by a thermal head provided with moved relative to each other insuch contact position to effect printing.
- a recording apparatus-using heat to transfer the information is known from U.S. Pat. No. 2,9l.7,996, but this known apparatus may still be said to be of an impact type in that recording paper is impacted by heated pins with a carbon tape interposed therebetween, and this type is similar to the ordinary impact printers as far as the noise problem is concerned.
- a i It is therefore'an object of the present invention to prevent a recording apparatus of the non-impact type which does not employ any special recording medium but the commonly used plane paper for the recording p p It is another object of the present invention to present a recording apparatus of the non-impact type which can record information on'recording paper free of any thermosensitive material by means of a thermal head.
- mon plane and selectively energizable for heating may be brought into intimate contact with a print member which in turn maybe brought into intimate contact with a web of recording paper, and in such position said islands may be selectively energized to effect printing on the recording paper by means of the print member.

- FIG. 1 therev is shown an embodiment of the recording apparatus according to the present invention, which includes a carriage 11 carrying thereon a thermal head holder member 12 and a pair of reels l4, 15 with a length of print ribbon or member 13 wound thereon.
- the carriage 11 is reciprocally movable along a rail 16.
- FIG. 2A is a perspective view of the carriage as viewed in the direction of arrow a in FIG. 1.
- the holder member 12 is formed of a thermally and electrically good conductive material such as aluminum or the like and provided with a groove 17 formed in a portion thereof.
- a base member 19 of ceramics or similar material carrying thereon a thermal head I8 is received in and secured to the groove 17 as by bonding.
- the holder member 12 is secured to the carriage 11 as by screws 20, 21.
- a cord 22 for applying electrical signals therethrough to the thermal head 18 extends downwardly along the groove 17.
- the thermal head 18 may be of any type which comprises exothermic elements arrayed in a matrix form on a common plane and selectively energizable. For example, as described in US. Pat. No. 3,496,333, it may comprise thermally independent semiconductor islands arrayed in a matrix form on a substrate, and semiconductor resistors disposed in said islands and adapted to be selectively energized.
- the holder member 12 at the opposite sides of the thermal head 18 there are provided guide grooves 23 and 24 which may be formed by bevelling the holder member I2 at portions thereof so as to ensure the print ribbon 13 to move over the thermal head 18 without deviating therefrom.
- the print ribbon I3 is disposed on the carriage 11 with the portion thereof between the reels l4 and 15 passing round the grooves 23, 24.
- One of the reels 15 which is rotatable to supply the ribbon l3 therefrom is securely mounted on the carriage 11, while the other reel 14 serving as the takeup reel is constructed with a gear 24 secured to the rotatable spindl elof the reel 14 by means of a one-way clutch (to be described) and meshing with a rack plate 23 so that the reel 14 is rotated in the direction of arrow d for takingup the ribbon 13 during the righteard stroke (the direction of arrow b) of the carriage 11 along the rail 16 and that the reel 14 stops itstake-up function when the carriage ll reverts to its leftward stroke (the direction opposite to that of arrow b).
- FIG. 2B is an exploded perspective view which more particularly shows the take-up reel 14 with respect to the print ribbon take-up portion thereof.
- the gear 24 meshing with the rack plate 23 has a hollow cylindrical drum. 25 securely mounted thereon, and a rotatable member 28 having a diameter slightly smaller than that of the drum 25 and provided with two wedge-shaped cut-away portions 26 and 27 is; rotatably mounted within the drum 25.
- Cylindrical retainer members 29 and 30 are inserted into the cut-away portions 26 and 27 of the rotatable member 28, and adapted to be biased by springs 31 and 32 into pressure contact with the walls of the wedgeshaped portions.
- the drum 25, the rotatable member 28, the retainer members 29, 30 and the springs 31, 32 together constitute a one-way clutch so that rotation of the drum in the direction of arrow d causes the retainer members 29 and 30 to be urged more against the wedge-shaped portions to thereby rotate the rotatable member 28 with the drum 25.
- the retainer members 29 and 30 will be driven in the direction to retract from the wedge-shaped portions so that the rotatable member 28 can not follow the rotation of the drum 25, thereby maintaining itself in a stationary position.
- the one-way clutch is so designed that rotation of the gear 24 in the direction of arrow d causes rotation of the rotatable member 28 but rotation of the gear 24 in the opposite direction results in stoppage of the rotatable member 28.
- a threaded bore 33 is formed centrally through the rotatable member 28 and a rotary spindle 35 is threadably inserted into the threaded bore 33 through an aperture formed through the carriage 11.
- the rotary spindle 35 has a flange 36 secured to an intermediate portion thereof, and the upper portion of the spindle above the flange 36 is formed as a'square rod for securely receiving thereon the reel 14 formed with a complementary square aperture 37.
- the carriage 11 thus carrying thereon the thermal head and print ribbon is slidably mounted on the rail 16 which has the opposite ends thereof rotatably supported by side plates 38 and 39.
- the rack plate 23 is disposed parallel to the rail 16 and these two members are secured together by fixing plates 40 and 41 in such a manner that the rack plate is always in mesh engagement with the gear 23.
- a roller 42 Extending between and rotatably journalled to the side plates 38 and 39 is a roller 42 for deflecting the recording paper, and a transport roller 43 extends below the roller 42 and is also rotatably journalled to the side plates 38 and 39.
- a holder member 44 extends along the path of travel of the thermal head and has the opposite ends thereof secured to the side plates.
- the holder member 44 has a resilient member 45 of rubber, felt or like material attached to one side thereof which faces thethermal head.
- a web of recording paper 46 on which recording isto be done by the thermal head, may be passed downwardly and then upwardly over the paper transport roller 43 and further between the resil ient member 45 and the thermal head.
- a paper transport motor 47 is provided to drive the papertransport roller 43 via a'belt connecting a pulley 48'on the shaft of the motor 47 to a pulley 49 on the paper transport roller 43, thereby driving the recording paper in one direction.
- a pulse motor 51 is provided to move the carriage and has a pulley 52 secured to the rotary shaft thereof. Another pulley 53 is rotatably mounted to a portion of the side plate 38. A length of wire 54 connects the two pulleys 52 and 53 and one end of the wire 54 is secured to the carriage 11, so that rotation of the pulse motor 51 will cause movement of the carriage 11 along the rail 16.
- a spring 55 is provided between and secured to one end of the rack plate 23 and an arm extending inwardly from the side plate 39 so as to bias the rack plate 23 upwardly.
- a plunger 56 Secured to said oneend of the rack plate is a plunger 56 which, when energized, may attract the rack plate 23 downwardly against the force of the spring 55. It will thus be seenthat, when the plunger 56 is not in energized condition,"the rail 16 is biased into counterclockwise rotation by the spring action to maintain the thermal head in pressure contact with the printing paper with the print ribbon interposed therebetween.
- the print ribbon 13 will be described in greater detail.
- the print ribbon or member 13 comprises a heatresistant back-up layer coated with a thin film of adhesive resin of low melting point fusible by a heat applied thereto, the thickness of the film being in the range of several microns to several tens of microns.
- adhesive resin used herein means a thermoplastic resin having no tackiness in itself at room temperature but fusible at low temperatures (say, from about C to about C) to present an adhesive property, such as resin materials of low melting point among phenol resin, maleic acid resin, rosin, epoxy resin, etc., and it is commercially available under the tradename such as Steabelite (manufactured by Herculuspowder Co.) or EPICOAT 1004" (manufactured by Shell Oil Co.)
- the print ribbon was prepared by uniformly mixing 5 grams of Steabelite, 1 gram of H.B.B. dye (tradename, by Orient Kasei Co.) and 50 millilitters of methyl ethyl ketone and by applying a thin layer of such mixture over a film of Myler (tradename for polyethylene terephthalate) having a thickness of 6 to 9 microns.
- H.B.B. dye tradename, by Orient Kasei Co.
- Myler tradename for polyethylene terephthalate
- the thermal head 18 may be moved in the direction of arrow in FIG. 3E by the pulse motor while the back-up layer 58 of the print ribbon may be progressively separated from the recording paper. In this way, only a portion of the adhesive resin which has melted may be solidified to remain on the recording paper 46 in the manner as shown in FIG. 3B.
- the recording apparatus of FIG. is in its print cycle during which the plunger 56 is in its deenergized condition or the carriage 11 is moving in the direction of arrow b, the rail 16 is biased counterclockwise by the spring 55 so that the thermal head 18 is in pressure contact with the recording paper 46 with the print ribbon l3 interposed therebetween.
- a signal for selectively energizing the islands of the thermal head may be applied through the cord 22 for a predetermined length of time, whereafter the pulse motor 52 may be energized to move the carriage 11 in the direction of arrow b by an amount corresponding to one printed character, whereby the gear 24 meshing with the rack plate 23 may be rotated in the direction of arrow d. Since the one-way clutch secured to the gear 24 transmits the rotation in the direction of arrow d to the rotatable member 28 as noted previously, the rotary spindle 35 is rotated to turn the take-up reel 14 in the direction of arrow d to thereby take up the print ribbon 13 in accordance with the amount of movement of the carriage 11.
- the plunger 56 may be energized to rotate the rail 16 clockwise against the force of the spring 55, so that the carriage 11 in turn is rotated clockwise about the rail 16 to bring the thermal head out of engagement with the recording paper while keeping an intimate contact with the print member.
- a drive signal may then be applied to the pulse motor Slto move the carriage 11 in the direction opposite to that of arrow b while the motor 47 may be energized to feed the recording paper by an amount corresponding to one print line.
- the pulse motor 51 and the plunger 56 may both be deenergized to permit the thermal head to be again urged against the recording paper with the print member therebetween, in preparation for the next print cycle.
- the gear 24 keeps mesh engagement with the rack plate 23 even during the described leftward stroke of the carriage 11, but the rotary spindle is prevented from rotating by the action of the one-way clutch during such stroke.
- FIG. illustrates another embodiment of the recording apparatus according to the present invention.
- a rail 5 2-extends between and is rotatably supported by side plates 50 and 51, and another rail 53 extends generally parallel to the rail 52. These two rails 52 and 53 are secured together in a predetermined spaced relationship by'fixing plates 54 and 55.
- a carriage 56 is slidably mounted on these rails and securely carries thereon a holder member 57 having a thermal head secured thereto, and a one-way roller 58 consisting of a oneway rotatable drum covered with a resilient material such as rubberor the like.
- a lever 59 is pivotally mounted on the carriage 11 by means of a pin 60.
- a pinch roller 6l' is rotatably mounted on a portion of the lever 60 and biased into engagement with the one-way roller 58 by a spring (not shown).
- The-thermal head is 'mounted'on the holder member 57 just in the same way as described with respect to FlG. 2A, and may be supplied with an electrical signal through a cord 62.
- the thermal head- is provided with print ribbon guide grooves similar to those described with respect to the previous embodiment.
- a pair of supply reel 63 and take-up reel 64 is provided for a length of print ribbon 65.
- the print ribbon 65 may be supplied from the supply reel 63 to pass over guide rollers 66, 67 and then over the thermal head and between the one-way roller 58 and the pinch roller 61, whereafter the ribbon may pass over guide rollers 68, 69 and onto the take-up reel 64.
- Means for holding the print ribbon therebetween are provided adjacent the guide roller 68.
- Such means may comprise a frictional member 70 of rubber or like material secured to an unshown fixed member such as chassis or the like, and a second frictional member 73 provided on a pivotable lever 72 in opposed relationship with the frictional member 70 so as to permit the print ribbon to intervene therebetween.
- the lever 72 is pivotable about a pin 71.
- a spring 74 is secured to one end of the lever 72 so as to bias this lever for counterclockwise rotation about the pin 71, i.e., for rotation in such a direction that the frictional member 73 is moved away from the other frictional member 70.
- Electromagnetic means 75 is provided in opposed relationship with another portion of the lever 72 so that the electromagnetic means, when energized, may actuate the lever 72 into clockwise rotation to thereby cause the two frictional members 70 and 73 to hold the print ribbon fixedly therebetween.
- a spring 76 is secured at one end to a portion of the rail 53 and at the other end to a chassis 76 so as to bias the rail 53 in the direction of arrow 2, i.e., so as to bias the rail 52 for clockwise rotation.
- a further plunger 78 is secured to a portion of the fixing'plate 54 so that the plunger, when energized, may actuate the rail 53 in the direction opposite to that of arrow e, i.e., so as to rotate the rail 52 in counterclockwise direction.
- a resilient member 79 of rubber, felt or like material is provided at a location where the thermal head on the holder member 57 bears against when the carriage 56 is moved along the rails 52 and 53.
- a wire 80 having one end secured to the carriage 56 is wrapped around a pully 82 on a pulse motor ,81 so that the carriage 56 may be moved along the rails 52, 53 by the drive from the pulse motor 81.
- Designated by numeral 83 is a web of recording paper which may be the commonly used plane paper instead of the special paper such as thermosensitive paper.
- the electromagnetic means 75 is energized to cause the frictional members 70 and 73 to hold the print ribbon 78 therebetween while the plunger 78 isin unenergized condition.
- the carriage 56 is biased for counterclockwise rotation about the rail 52 to, thereby urge the unshown thermal head against the recording paper 83 with the print ribbon 65 intervening therebetween.
- the pulse motor 81 is energized to drive the carriage 56 leftwardly. Since the roller 58 is rotatable only in one direction and unrotatable in the other direction, this roller 58 cooperates with the roller 61 to hold the print ribbon 65 therebetween. Thus, the leftward movement of the carriage 56 causes the print ribbon to be transported from the reel 63. Since the other reel 64 is biased by an unshown mechanism in the direction for taking upthe print ribbon,the successive portions of the print ribbon transported with the leftward movement of the carriage 56 may be taken up on the reel 64.
- the recording paper' is advanced upwardly by an amount corresponding to one print line, by an unshown means.
- the electromagnetic means 75 is again energized to cause the frictional members 70 and 73 to hold the print ribbon 65 therebetween'while the plunger 78 is deenergized to permit the thermal head to be urged against the recording paper with the print ribbon interposed therebetween. It is now possible to start a new line printing by applying a drive signal from the cord 62 to the thermal head.
- FlGS. 6 and 7 illustrate still another embodiment of the recording apparatus according to the present invention in which printing can be provided on the recording paper only with the feed movement of the paper and of the print member.

- the thermal head assembly as shown in FIG. 6 is exclusively for use in numerical printing and comprises a row of 8-shaped elements, each of which comprises separately energizable, independent islands formed in a common plane and corresponds to one character.
- Such thermal heads 90 each comprising S-shaped elements are secured to the holder member 91 which may be formed of aluminum or other thermally and electrically good conductor, and a cord 92 isprovided forthe application of electrical signals to the thermal head.
- an exothermic unit is constituted as generally designated by 93.
- such exothermic unit 93 is secured to an unshown chassis or the like and a resilient member'97 is fixedly disposed in opposed relationship with the thermal head of the heating unit.
- A' web of recording paper 95v free of any thermosensitiv'e'material and a pri'ntmember 96 similar to the above-described one are supplied in overlapped relationship to a paper transport roller 94, so that the recording paper and the print member are sandwiched between the thermal head 90 and the resilient member 96, with the print member being contacted by the thermal head and with the recording paper being contacted by the print member.
- the paper transport roller 94 is directly connected to a pulse motor 98 and has a pulley 99 mounted on a portion thereof.
- the pulley 99 is connected to a pulley 101 on a print member take-up roller 100 by a belt 102 so that energization of the pulse motor 98 causes the recording paper and the print member to be fed-into between the thermal head assembly 90 and the resilient member 97 and that the print member having passed the thermal head assembly is taken up on the takeup roller 100.
- the print cycle continues throughout the operating time with the thermal head assembly continuously urged against the recording paper with the print member interposed therebetween.
