Printing device for printing image on tape like member

Abstract: A printing device (1) for selectively printing either a normal posture character image or a reverse posture character image on a tape-like image receiving member (25, 57) using a thermal head (17). In the normal posture character image printing, a non-lamination type printing tape (25) is used in which an imaging surface (25a) is exposed to the atmosphere. In the reverse posture character image printing, a lamination type printing tape (57) is used in which the imaging surface is protected by a transparent tape. A tape cartridge (21) which stores the non-lamination type printing tape and another tape cartridge (23) which stores the lamination type printing tape are both insertable into the same printing device. Depending on the type of cassette inserted into the printing device, the device is operated either in the normal or the reversed character image printing mode.

Description: The present invention relates to a printing device for printing an image on a tape-like member. Conventionally, a printing device for printing an image on a tape like image receiving member has been proposed. According to the conventional printing device, a tape cartridge which accommodates therein a tape and an ink ribbon is assembled in a main body of the printing device for printing an image on the tape. U. S. Patent 4,815,871 discloses such printing device in which a normal character image is printed on a non-adhesive surface of an adhesive tape provided with a releasable sheet, the printed surface being directly exposed to an atmosphere (this printing can be referred to as "non-lamination type printing" in which the imaging surface is not covered with any lamination layer for the purpose of image protection). Here, the "normal character image printing" implies that the printed image has a normal posture when viewing the resultant printed tape from the imaging side (see Fig. 6(a)). The tape printed with the image is adhered to a tape receiving member in such a manner that the printed image is directly exposed to the atmosphere. On the other hand, EP-A-0 322 918 (U. S. Patent 4,927,278) discloses another type of printing to the tape like member. The tape employed has transparency to which a reversed character image is printed. The imaging surface of the transparent tape is superposed with dual sided adhesive tape provided with a releasable sheet (this printing can be referred to as "lamination type printing" in which the imaging surface is covered with another tape for the purpose of image protection). Here, the "reversed character image printing" (Fig. 6(b)) implies that the printed image has a normal posture when viewing the resultant printed tape from a side opposite the imaging side. When the printed tape is adhered to a tape receiving member, the transparent tape is positioned as a top layer which protects the imaging surface, and the initially reversed image is then visible through the transparent tape in the normal character image. The lamination type printing has advantages in that the imaging surface can be protected by the top layer, to thereby enhance durability of the printed portion. However, this also provides drawback in that the structure of the tape cartridge becomes complicated, which leads to high production cost. In case of the non-lamination type printing, in contrast, even though simplified arrangement for the printing device can be provided, the printed surface is not protected by any laminated layer but is exposed to the atmosphere, to thereby degrade its durability Accordingly, conflicting problems exists in both lamination type and non-lamination type printing methods. If a tape cartridge for the lamination type is installed in a non-lamination type tape printer which provides the normal character image on the tape and printing is carried out to the tape, resultant printing image on the tape receiving member is reversed, since the imaging surface is observed from a side opposite tie imaging surface of the tape. On the other hand, if a tape cartridge for the non-lamination type is installed in the lamination type tape printer which provides the reverse character image on the tape and printing is made, the reverse character image is to be observed when the tape is adhered to the tape receiving member, since the imaging surface is directly observed from the imaging surface. A label printing apparatus produced by Varitronics and known as the MERLIN EXPRESS ELITE was apparently put on sale in the USA in March 1988. The MERLIN EXPRESS ELITE device is discussed in a Varitronics manual also apparently made available in 1988. The Varitronics manual refers to the MERLIN EXPRESS ELITE printing apparatus as being capable of taking tapes of ½" and 1" width. The MERLIN EXPRESS ELITE allegedly included a tape width detector for providing the device with the ability to discriminate between different widths of tape. The MERLIN EXPRESS ELITE device was apparently capable of printing in so-called "Inverted Type (Mirror Image" mode, in which mode the text was inverted to enable the label to be used on a glass door or window for example so as to be read from the outside. The MERLIN EXPRESS ELITE device was also capable of printing normally, i.e. not inverting the printed text. Operation of the MERLIN EXPRESS ELITE device was switched manually between the normal and "Inverted Type (Mirror Image)" printing modes. According to a first aspect of the present invention there is provided a printing device which includes printing means and which is for producing printed tapes using tape materials of at least two types provided in rolls within cartridges of respective different types, the tape materials being unwound and fed from the cartridge upon printing and including at least an image receiving member having an image receiving surface on which the printing means can form an image, and the cartridges of the respective different types each having a discriminating portion which represents its respective type, the printing means being operable in at least a normal image printing mode and a reversed image printing mode respectively appropriate for tapes in the two different types of cartridge, the printing device having tape cartridge accommodation means for receiving a cartridge containing tape to be printed, a feeding mechanism for feeding the tape materials in a first direction and memory means for storing therein character patterns; the printing means including a print head having an array of a plurality of image forming elements for transferring ink to form an inked image on the image receiving member, the array extending in a second direction transverse to the first direction; the device including print head driving means connected to the print head for selectively driving at least one of the image forming elements in accordance with printing data and a character pattern read from the memory means; signal generation means for generating one of a normal image printing mode signal and a reversed image printing mode signal, the normal image printing mode signal corresponding to the tape materials being of a first type and the reversed image printing mode signal corresponding to the tape materials being of a second different type; and switching means for causing the print head to operate in the normal image and reversed image printing modes selectively, the switching means being connected to the print head driving means to, in the normal image printing mode, normally drive the image forming elements so that the printed image has a normal orientation when viewed from a front surface of the tape-like image receiving member and to, in the reversed image printing mode, reversely drive the image forming elements with respect to the second direction in order to turn the character pattern about with respect to the second direction so that the printed image has a normal orientation when viewed from a back surface of the tape-like image receiving member; control means for selectively actuating the switching means in response to the normal and reversed image printing mode signals from the signal generation means; and the device including, in the accommodation means, tape cartridge discrimination means for discriminating between different types of tape cartridge by cooperating with the discriminating portions and providing an input to the signal generation means whereby to cause the signal generation means to generate either said normal image printing mode signal or said reversed image printing mode signal according to the type of the discriminated tape cartridge to cause the printing means to print in the said printing mode appropriate to the type of the discriminated tape cartridge. According to a second aspect of the present invention there is provided a printing device of the construction of the first aspect of the present invention, in combination with a tape cartridge for use in the printing device, the tape cartridge of said combination comprising: a cartridge case formed with an outlet port; a rotation shaft rotatably supported in the cartridge case; a tape-like image receiving member having an image receiving surface on one side thereof on which an image is formable by the printing means, the tape-like image receiving member being wound around the first rotation shaft and being unwindable for discharge from the cartridge case through the outlet port; and a discriminating portion arranged to cooperate with the tape cartridge discrimination means of the printing device and indicative of the type of tape cartridge. The present invention will be further described hereinafter with reference to the following description of an exemplary embodiment and the accompanying drawings, in which: Fig. 1 is a party exploded perspective view showing a printing device and its tape cartridge according to an embodiment of this invention; Fig 2 is a plan view showing an internal arrangement of a tape cartridge in which a normal character image can be printed according to the embodiment of this invention; Fig 3 is a plan view showing an internal arrangement of another tape cartridge in which a reverse character image can be printed according to the embodiment of this invention; Fig 4 is a block diagram showing a control circuit of the printing device according to the embodiment of this invention; Fig. 5 is a perspective view particularly showing a thermal head according to the embodiment of this invention; Fig. 6(a) is a plan view showing a printed tape in which a normal character images are printed; and Fig. 6(b) is a plan view showing a printed tape in which a reversed character images are printed. A printing device according to the embodiment of this invention will be described with reference to Figs. 1 to 6(b). Fig. 1 shows a rear perspective view of the printing device 1. The printing device includes a tape cartridge holding portion 5 for holding a tape cartridge 3 formed with an opening portion 19 and installing a printing tape 25. In the tape cartridge holding portion 5, a ribbon take-up cam 7 and a tape feed roller cam 9 are provided. These cams 7 and 9 are drivingly coupled to a drive motor 11 (Fig. 4) housed within an outer frame 1a of the printing device, and are rotatable in directions indicated by arrows in Fig. 1. The tape cartridge holding portion 5 is further provided with a movable projection 13 movable in a vertical direction. The movable projection 13 is normally biased toward the rear wall of the outer frame 1a (upwardly in Fig. 1). However, when the movable projection 13 is urged to be depressed into an interior of the frame 1a, the projection 13 will actuate a detector 15 (Fig. 4) provided within the outer frame 1a and connected to a control means described later with reference to Fig. 4) of the printing device 1. The tape cartridge holding portion 5 is also provided with a thermal head 17. The thermal head 17 is adapted to be confronted with the opening portion 19 of the tape cartridge 3 when the latter is assembled to the tape cartridge holding portion 5. The thermal head 17 is provided with an array of a plurality of heat generating elements 18, the array being directed perpendicular to a feeding direction of the printing tape as best shown in Fig. 5. For the tape cartridge 3, two different kinds of the tape cartridges, i. e. a non-lamination type tape cartridge 21 and a lamination type tape cartridge 23 are prepared as shown, respectively in Figs. 2 and 3. Referring first to the non-lamination type tape cartridge 21 shown in Fig. 2, a rotation shaft 29 is rotatably provided over which a rolled printing tape 25 is wound in a form of a tape roll 27. As described above, the printing tape 25 has one printing surface 25a to which an image is formed by the thermal head 17 and an opposite surface at which adhesive layer is formed to adhere a releasable tape. Within the tape cartridge 21, provided are an ink ribbon roll 33 of an ink ribbon 31 whose one surface is coated with an ink, and a take-up spool 35 to which a leading end of the ink ribbon 31 is fixed. The ink ribbon roll 33 is wound over a ribbon roll shaft 37 rotatably supported by a cartridge case 28. The take-up spool 35 has an inner peripheral surface 41 at which engaging protrusions 43 are protruded radially inwardly. The take-up spool 35 is rotatably supported by a hole 45 formed in the cartridge case 28. This ink ribbon take-up spool 35 is provided engageable with the ink ribbon take-up cam 7 when the take cartridge 21 is assembled into the tape cartridge holding portion 5. The printing tape 25 and the ink ribbon 31 are both fed to the opening portion 19a. However, after these are fed past the opening portion 19a, the ink ribbon 31 is directed to the ink ribbon take-up spool 35 as shown by a broken line in Fig. 2 whereas the printing tape 25 is discharged out of the cartridge case 28. The printing surface 25a of the printing sheet 25 confronts the inking surface of the ink ribbon 31. When the tape cartridge 21 is assembled to the tape cartridge holding portion 5 of the printing device 1, the printing tape 25 and the ink ribbon 31 are brought into pressure contact with each other at the opening portion 19a by the thermal head 17 and a pressure contact/release member 55. In this case, the printing surface 25a of the printing tape 25 is confronted with the thermal head 17. In other words, the printing surface 25a is positioned at radially inner side of the tape roll 27, and the inking surface of the ink ribbon 31 is positioned at radially inner side of the ink ribbon roll 33. In the tape cartridge 21, a tape feed roller 47 is rotatably provided at a position adjacent the opening portion 19a. This tape feed roller 47 is rotatably secured to a hole 49 formed in the cartridge case 28, and engagement protrusions 51 are radially inwardly protruded from an inner peripheral surface of the tape feed roller 47. When the tape cartridge 21 is assembled to the tape cartridge holding portion 5 of the printing device 1, the engagement protrusions 51 of the tape feed roller 47 are brought into engagement with the tape feed roller cam 9. The tape feed roller 47 is positioned in confrontation with a rotatable roller 55a secured to the pressure/release member 55. Further, a rectangular hole 53 is formed in the cartridge case 28. This rectangular hole 53 is positioned so that the movable projection 13 is aligned therewith when the tape cartridge 21 is assembled to the tape cartridge holding portion 5. In this assembling state, the movable projection 13 is positioned within the rectangular hole 53. Therefore, the protruding state of the movable projection 13 is maintainable (a wall of the tape cartridge does not depress the movable projection 13 into the interior of the frame 1a, i.e., upward position of the movable projection 13 in Fig. 1 can be maintained). Upon assembly of the tape cartridge 21 into the tape cartridge holding portion 5, the ink ribbon take-up cam 7 and the tape feed roller cam 9 are engaged with the ink ribbon take-up spool 35 and the tape feed roller 47, through the protrusions 43 and 51, respectively, and these are rotated in directions indicated by arrows in Fig. 2. In this case, the tape feed roller contacts the printing tape 25 under pressure in cooperation with the rotatable roller 55a of the pressure contact/release member 55. By the rotation of the tape feed roller 47, the printing tape 25 is discharged out of the tape cartridge 21. In view of the foregoing, according to the tape cartridge 21 shown in Fig. 2, when it is assembled to the printing device 1, the printing surface 25 is subjected to printing by the thermal head 17 through the ink ribbon 31. The selective actuations of the heat generating elements 18 of the thermal head 17 produce normal image as shown in Fig. 6(a) on the printing surface 25a opposite the releasable tape side 25b by thermally transferring ink of the ink ribbon 31 to the printing surface 25a, and the printed tape 25 is discharged by the rotation of the tape feed roller 47. Next, a lamination type tape cartridge 23 will be described with reference to Fig. 3. The tape cartridge 23 has a cartridge case 61 at which a rotation shaft 63 is provided. A tape roll 59 of a printing tape 57 is rotatably wound over the rotation shaft 63. The printing tape 57 is formed of a transparent film-like material, so that even if a reversed image is printed on one printing surface of the transparent tape 57 the printed image is visible as a normal image when viewing it from the opposite surface of the transparent tape 57. The printing tape 57 can be introduced into an opening portion 19b by a guide member provided in the cartridge case 61. In the tape cartridge 23, another rotation shaft 69 is rotatably provided, and a roll 67 of a dual sided adhesive tape 65 is wound over the rotation shaft 69. The dual sided adhesive tape 65 has both front and rear surfaces formed with adhesive agent, and a releasable tape is adhered to one adhesive surface thereof. Moreover, similar to the non-lamination type tape cartridge 21, there are provided an ink ribbon roll 73 of an ink ribbon 71, a take-up spool 75 for winding the ink ribbon 71 and a tape feed roller 77 for feeding the printing tape 57. Upon assembly of the tape cartridge 23 into the tape cartridge holding portion 5, the printing tape 57 is urged to be depressed onto the thermal head 17 through the ink ribbon 71 by the pressure contact/release member 55. Further, the printing tape 57 and the dual sided adhesive tape formed with the releasable tape are interposed between the tape feed roller 77 and the rotatable roller 55a. When the tape feed roller 77 is rotated in a direction indicated by an arrow in Fig. 3, the printing tape 57 and the dual sided tape 65 are discharged from the tape cartridge 23. In this case, the printing surface of the printing tape 57 is in facial contact with the adhesive layer of the dual sided adhesive tape 65. Thus, the printing tape 57 and the dual sided tape 65 becomes integral with each other at the tape discharge. In the lamination type tape cartridge 23, the printing tape 57 is integral with the dual sided adhesive tape 65, and the printed or imaging surface of the printing tape 57 is protected by the adhesive tape 65. The printed image is observed from a side opposite the printed surface. To this effect, the thermal head 17 produces a reversed image on the printed surface of the tape 57 as shown in Fig. 6(b). The reversed image is provided by turning the normal image by 180 degrees with respect to a line perpendicular to the tape feeding direction indicated by an arrow in Fig. 6(b). In other words, the reversed image is turned by 180 degrees from the normal image position with respect to a direction of an array of the heat generating elements 18 of the thermal head 17. It should be noted that the lamination type tape cartridge 23 is not formed with a hole corresponding to the rectangular hole 53 shown in Fig. 2. Therefore, when the tape cartridge 23 is assembled into the tape cartridge holding portion 5, the wall of the tape cartridge 23 abuts the movable projection 13 and depresses the movable projection 13 into the interior of the frame 1a against the biasing force applied to the projection 13. Fig. 4 shows one example of a control arrangement applied to the printing device 1 which can selectively provide normal or reversed image with selective employment of the non-lamination type tape cartridge 21 or the lamination type tape cartridge 23. According to the control arrangement, a CPU 81 is provided for overall processing, and to the CPU 81 connected are ROM 83, a RAM 85, a key board 87, the detector 15, a motor driver circuit 89 and a heat generating element driver circuit 91. The motor driver circuit 89 is connected to the drive motor 11, and the heat generating element driver circuit 91 is connected to the heat generating elements 18 of the thermal head 17. The ROM 83 stores therein a program which control operations of the CPU 81 and character patterns for the character printing. The key board 87 is adapted for inputting the print character data into the CPU 81 for obtaining a desired print character image. As described above, the detector 15 detects the movable projection 13. That is, if the non-lamination type tape cartridge 21 is assembled to the printing device 1, the movable projection 13 is not depressed into the interior of the frame 1a. Therefore, the detector 15 does not detect the movable projection 13, which is indicative of the assembly of the non-lamination type tape cartridge. On the other hand, if the lamination type tape cartridge 23 is assembled, the movable projection 13 is depressed into the interior of the frame 1a. Therefore, the detector 15 detects the movable projection 13, which is indicative of the assembly of the lamination type tape cartridge 23. Thus, the CPU 81 can determine, through the detector 15, as to which one of the tape cartridges is installed in the printing device 1. The motor driver circuit 89 is adapted to control the drive motor 11 in accordance with a tape feed data sent from the CPU 81. The tape feed data is provided upon manipulation to the key board 87. The heat generating element driver circuit 91 controls actuations of the respective heat generating element 18 in response to the character print data sent from the CPU 81. The CPU 81 provides the character print data in such a manner that order of the elements 18 in the array is selectively reversed in accordance with the result of the detection of the movable projection 13 by the detector 15. With this arrangement, if the non-lamination type tape cartridge 21 is assembled to the holding portion 5, the movable projection 13 maintains its protruding state. Therefore, the detector 15 does not detect the projection 13. Therefore, determination in the CPU 81 falls that the non-lamination type tape cartridge 21 is installed, and the normal character printing is to be carried out. Accordingly, the CPU 81 transmits data indicative of the normal character printing to the heat generating element driver circuit 91. In this case, the direction of one character is coincident with the direction of the array of the heat generating elements 18 (downwardly in Fig. 5). On the other hand, if the lamination type tape cartridge 23 is installed in the printing device 1, the movable projection 13 is depressed inwardly by the wall of the cartridge 23, so that the detector 15 can detect the projection 13. Therefore, determination in the CPU 81 falls that the lamination type tape cartridge 23 is installed and the reverse character printing is to be carried out. Accordingly, the CPU 81 transmit data indicative of the reverse character printing to the heat generating element driver circuit 91. In this case, the direction of one character is opposite the direction of the array of the heat generating elements 18. Of course, the manipulation to the key board 87 will provide the intended character images while feeding the printing tape. The releasable tape adhered to the printing tape 25 or the dual sided tape 65 is removed, so that the adhesive layer is exposed and the printing tape can be adhesively attached to an intended object or a tape receiving member. The tape feed roller cam 9 and the drive motor 11 are the feed mechanism, the thermal head 17 and the heat generating elements 18 are the print head, the heat generating element driver circuit 91 is the print head driving means, the CPU 81 and ROM 83 are the memory means, the CPU 81 is the signal generation means, the CPU 81, the movable projection 13 and the detector 15 are the switching means, and the CPU 81 is the control means. Further, the movable projection 13, the hole 53 and the detector 15 are the discrimination means. In view of the foregoing, according to the present invention, normal character image and reversed character image can be selectively printed on the tape like image receiving member. Therefore, the printing device of this invention is available for both non-lamination type printing and lamination type printing.
