Definitions

  • the present invention relates to a recording apparatus for printing images such as characters, marks, and the like on a recording medium, and more particularly to a recording apparatus capable of cutting a recorded portion of a long-sized recording medium to be used.
  • a recording apparatus is conventionally provided with a recording head, a platen for supporting recording paper which is fed with respect to the recording head, and a cutting unit disposed in a downstream side of the platen, for cutting the recording paper.
  • this paper upon completion of recording using the recording head on the recording paper, this paper is fed toward the cutting unit and is cut by the cutting unit.
  • the present invention has been made in view of the above circumstances and has an object to overcome the above problems and to provide a recording apparatus capable of preventing the occurrence of white lines and extreme overlap between recorded portions of a recording medium before and after a cutting operation.
  • a recording apparatus of this invention comprises a recording head having an arrangement row of recording elements, a feeding means for feeding an elongated recording medium in a direction of the arrangement row of recording elements with respect to the recording head, the feeding means feeding the recording medium by a first length approximately corresponding to a length of the arrangement row of the recording elements, a cutting unit for cutting the recording medium, disposed downstream of the recording head along a feeding direction of the recording medium, a first control means for controlling the feeding means to stop while a recording operation being performed with the recording head, and a second control means for controlling the feeding means to feed the recording medium by a second length less than the first length just before a cutting operation by the cutting unit and to feed the recording medium by a third length left by subtracting the second length from the first length after the cutting operation.
  • the second control means controls to feed the recording medium by a second feeding amount less than the first length just before a cutting operation by the cutting unit and by a remaining third amount after the cutting operation, and then controls the recording head to perform recording again on the recording medium. Accordingly, even if backlash is produced in the gear train used for a feeding mechanism for feeding the recording medium, resulted from that the recording medium is pulled by the cutter and the like of the cutting unit, it is sufficient to regulate the feeding amount of the recording medium corresponding to the backlash in feeding the recording medium by the remaining amount. This can prevent white lines and extreme overlap between recorded portions on the recording medium before and after the cutting operation.
  • a recording apparatus in the embodiment is a tape printing apparatus 1 for printing various images such as characters including alphabets and symbols, etc., and marks on a recording medium (tape) having a small or large width.
  • a tape station TS for recording the images with single color on a small-width recording medium D1 as a first recording medium
  • a wide station WS for recording the images with any of multiple or single color(s) on a large-width recording medium D2 as a second recording medium.
  • the tape printing apparatus 1 discharges the first recording medium D1 printed with a single color in the tape station TS from a discharge port (not shown) formed in a side wall (in a left side in Fig. 1) of a main body frame 2, alternatively, the second recording medium D2 printed with multiple or single color(s) in the wide station WS from another discharge port 2a formed in the substantially center of a front face of the main body frame 2.
  • a keyboard 3 has a return key, a plurality of character keys for inputting alphabet and other characters, mark keys, and further various keys, for example, edition keys such as a cancel key, selection keys for selecting a vertical/lateral printing.
  • the keyboard 3 is connected to the tape printing apparatus 1 through a cable 4, whereby signals representing data input with the various keys of the keyboard 3 can be transmitted to the tape printing apparatus 1.
  • a display 5 On the front right face of the main body frame 2 (in a right side in Fig. 1), also provided is a display 5 for displaying thereon the images such as characters and others input with the keyboard 3 in a plurality of lines.
  • a cover 7 is provided in another side (left side in Fig. 1) of the front face of the main body frame 2. This cover 7 can be opened forward. Accordingly, an user can open the cover 7 and insert, on a carriage CA, one of a tape cassette TC to be used for a recording operation in the tape station TS and an ribbon cassette RC of multiple or single color(s) to be used for a recording operation in the wide station WS according to which recording medium the user makes a choice, the first recording medium D1 or the second medium D2.
  • the tape printing apparatus 1 in the embodiment records images with a single color on the first recording medium D1 in the tape station TS.
  • the invention is not limited to this embodiment and may be modified to be printable with full colors.
  • Fig. 2 is a front view of main components of a recording mechanism of the tape printing apparatus 1 and Fig. 3 is a plane view of the same.
  • the tape station TS is a recording area disposed at a left side in the drawings of a base chassis HS of the main frame 2, as shown in Figs. 2 and 3.
  • the wide station WS is another recording area disposed at a right side in the drawings of the base chassis HS.
  • a recording operation is performed in a line recording mode wherein the first recording medium D1 drawn out of the tape cassette TC and an ink ribbon IR to be used for recording the images on the first recording medium D1 are fed in the same direction, namely, in a sideward direction toward the outside of the main frame 2, and the recording head (thermal head) HD fixedly supported on the carriage CA records images through the ink ribbon IR on the first recording medium D1. A recorded part of the first recording medium D1 is then discharged through the discharge port formed at the side of the main frame 2.
  • a recording operation is conducted on the second recording medium in a serial recording mode by moving the recording head HD in a main scanning direction, i.e., in a lateral direction in Figs 2 and 3, which intersects a feeding direction of the second recording medium D2, i.e., in an up and down direction in Fig. 3.
  • the second recording medium D2 is fed by a predetermined amount in the feeding direction, and the recording head HD records again while being moved in the main scanning direction.
  • a carriage moving mechanism CH moves the carriage CA mounting thereon the recording head HD reciprocatingly in the main scanning direction intersecting the feeding direction of the second recording medium D2
  • the recording head HD records images such as the characters "ABCDE” in a line in the main scanning direction and "FGHI” in another line at the same time, as shown in Fig. 4(b), on the second recording medium D2.
  • a feeding mechanism QH feeds the second recording medium D2 by a predetermined amount in correspondence with an arrangement length L1 of a plurality of heating elements serving as recording elements (see Fig. 4(a)) in the feeding direction, i.e., in an up and down direction in Fig. 3.
  • the carriage moving mechanism CH moves again the carriage CA in the main scanning direction with respect to the second recording medium D2, and the recording head records the characters "JKLMN" in a third line on the second recording medium D2, then repeating the same processing as above.
  • the feeding amount of the second recording medium D2 can be reduced by an amount corresponding to one or several heating element(s) than the length L1 of the arrangement of the heating elements.
  • the recording medium D2 is fed so that a back end of the recorded portion of the first line in the feeding direction of the recording medium D2 and a front end of the recorded portion of the second line are overlapped with each other by the length corresponding to one or several heating element(s), i.e., dot(s), which prevents the production of gap between the back end of the first line and the front end of the second line.
  • dot(s) which prevents the production of gap between the back end of the first line and the front end of the second line.
  • the feeding amount of the recording medium D2 can be controlled to correspond to the length L1 of the arrangement row of the heating elements or less than the same by one or several heating elements.
  • the recording medium D2 is thus fed by a feeding amount almost corresponding to the length of the heating element row.
  • this carriage moving mechanism CH is provided with a step motor SM disposed at a right side in the main frame 2, a small diameter gear SM2 attached so as to mesh with a driving shaft SM1 of the motor SM, a large diameter gear SM3 meshing with the gear SM2, a driving pulley SP2 which rotates integrally with the gear SM3 for rotating a timing belt, a follower pulley SP1 disposed in a left side in the main frame 2, which feeds the timing belt in cooperation with the driving pulley SP2, the timing belt TB laid over the pulleys SP1 and SP2 and secured to a rear end portion CA1 of the carriage CA, and a guide rod GD extending between both side walls of the main frame 2, penetrating a rear end portion CA2 of the carriage CA for supporting the carriage CA.
  • a guide rod GD extending between both side walls of the main frame 2, penetrating a rear end portion CA2 of the carriage CA for supporting the carriage CA.
  • the step motor SM When the step motor SM is driven to rotate regularly or reversely, the driving pulley SP2 is rotated in a direction or reverse through the driving shaft SM1 and the driving gears SM2 and SM3, moving the timing belt TB in a direction or reverse.
  • the carriage CA on which the recording head HP is mounted is moved by step-feeding between the pulleys SP1 and SP2 along the guide rod GD in a lateral direction in Figs. 2 and 3, whereby the carriage CA can be positioned at the tape station TS as shown by a solid line in Figs. 2 and 3 or can be moved reciprocatingly within the recording area of the wide station WS as shown in a two-dot chain line in Figs. 2 and 3.
  • a pulse number for controlling the step motor SM exactly corresponds to a feeding amount of the timing belt TB.
  • the timing belt TB is fed by a predetermined amount, thereby precisely moving the carriage CA.
  • the feeding mechanism QH for the second recording medium D2 is provided with support members ST1 and ST2 for supporting the second recording medium D2 as a rolled state, disposed in the back side of the main frame 2, paper feeding roller members JR1 and JR2 disposed in that order, parallel to the main scanning direction and separately from each other by a predetermined distance in the feeding direction (sub-scanning direction) of the second recording medium D2. More specifically, the supporting members ST1 and ST2 are respectively secured between a long side chassis HS2 of the chassis HS and a chassis KS. These supporting members ST1 and ST2 are inserted from both sides of the rolled second recording medium D2 into an axial hollow portion D2a thereof to support the second recording medium D2 (see Figs. 4). It is noted that a cassette case HSO shown by a two-dot chain line in Figs. 4(a) and 4(b) is preferably used to accommodate therein the rolled second recording medium D2, but it is not limited thereto.
  • a compression spring AB is attached to the supporting member ST1 fixed to the base chassis HS thereby to bias the supporting member ST1 toward the chassis KS.
  • the supporting member ST2 fixed to the chassis KS is movable toward the supporting member ST1 in correspondence with a width of the second recording medium D2, as shown by a one-dot chain line in Fig. 3. Accordingly, both the supporting members ST1 and ST2 can surely support the second recording medium D2 as rolled according to different widths of the second recording medium D2, for example, shown by a solid line or a two-dot chain line in Fig. 3.
  • the top end of the second recording medium D2 can thus be fed toward the roller members JR1 and JR2.
  • roller members JR1 and JR2 are each disposed rotatably between the long side chassis HS2 of the base chassis HS and the chassis KS secured in the wide station WS side, as mentioned above.
  • a step motor SN is mounted on a short side chassis HS1 of the base chassis HS in the tape station TS side.
  • Driving power of the motor SN in being regularly or reversely rotated is transmitted through a gear train GY disposed parallel to the long side chassis HS2 to the roller members JR1 and JR2 and the supporting member ST1, thereby rotating them clockwise or counterclockwise.
  • the gear train GY includes gears Y1 - Y7, ST3, and ST4 and others which will be described in detail.
  • the roller member JR1 is constructed of a pair of roller shafts JR1a and a plurality of separate rollers JR1b mounted on each of the upper and lower roller shafts JR1a, the rollers JR1b mounted respectively on the upper and lower shafts JR1a being in firmly contact to each other.
  • the roller member JR2 has the substantially same structure as the JR1a. With those roller members JR1 and JR2, the top end of the second recording medium D2 is caught between the rollers JR1b of the roller members JR1 and then between the rollers JR2b of the roller members JR2, so that the second recording medium D2 is fed forward in accordance with the rotation of the roller members JR1 and JR2 or backward to be rewound.
  • a second platen P2 is provided on the base of the main frame 2, below the carriage CA moving parallel to and between the roller members JR1 and JR2.
  • This second platen P2 is designed to have a substantially flat surface on which the second recording medium D2 is to be supported. If the second platen P2 is a cylindrical platen, the row of the heating elements of the recording head HD is orthogonal to the axis of the second platen P2, the heating elements in both sides of the row can not be fully in contact under pressure against such the cylindrical platen, so that it will tend to result in patchy and missing recorded medium. Consequently, to prevent the above problem, a flat platen is preferably used as the second platen P2.
  • a sensor mark SX is formed to be used for detecting a home position of the recording head HD in the wide station WS in the reciprocating movement of the recording head HD along the guide rod GD.
  • the home position based on the mark SX of the second platen P2 is a standard point for controlling the position of the recording head HD.
  • the mark SX is formed of two patterns each having a reflection part and a non-reflection part alternately arranged, and attached on the second platen P2.
  • a reflecting sensor (not shown) mounted on the carriage CA detects the mark SX as a target.
  • the control unit CP determines the position where the reflecting sensor detects twice a change point from the reflection part to the non-reflection part as the home position of the carriage CA.
  • the reason why the mark SX has two patterns is that if only one change point is used, the control unit CP should determine by mistake a border of a white recording medium D2 with respect to a black platen P2 as the change point. Accordingly, it is preferable to form the sensing mark SX having two patterns as above to prevent the error detection.
  • a detection sensor SW for detecting the top end of the second recording medium D2.
  • the second recording medium D2 is controlled to be fed in accordance with output signals from the sensor SW. For example, when the user sets the second recording medium D2 in a predetermined part of the main frame 2 and feeds the top end of the medium D2 toward the paper feeding roller members JR1 and JR2, the second recording medium D2 can be fed further forth.
  • the step motor SN is driven to regularly rotate, this regular rotation of the step motor SN is transmitted through the gear train GY to the both roller members JR1 and JR2 and the supporting member ST1 respectively, thus rotating them.
  • the control unit CP continuously drives the step motor SN until the sensor SW detects the top end of the second recording medium D2. It is noted that the control pulse number of the step motor SN exactly corresponds to the feeding amount of the recording medium D2, unless feeding errors such as a zigzag feeding.
  • the control unit CP controls, accordingly, the recording medium D2 to be fed by transmitting a predetermined number of pulses to the step motor SN.
  • a cutter unit KC for cutting the second recording medium D2 is disposed downstream of the roller member JR2. This cutter unit KC is operated timely to cut the recording medium D2 under feeding control. Any type of cutter unit KC, as long as it can cut the recording medium D2, may be used.
  • a type of cutter unit is to cut the second recording medium D2 with a blade KC1 (see Fig. 4 (a)) reciprocating in the width direction of the recording medium D2 (in a lateral direction of Fig. 3), another is to cut the same with a different blade KC1 having a length substantially corresponding to the width of the recording medium D2, movable up and down.
  • control unit CP conducts the following control operation in order to prevent the generation of white lines and extreme overlapping between portions recorded before and after the cutting operation.
  • the control unit CP controls to feed the top end of the recording medium D2 by a length each, generally, corresponding to the arrangement row (L1) of the heating elements as shown in Figs. 26(a) and (b) and to drive the recording head to record on the recording medium D2 after stopping it.
  • the recording head HD is driven again to record on the recording medium D2.
  • the control unit CP drives the roller members JR1 and JR2 to rotate thereby to feed the top end of the recording medium D2 by the length L1 of the heating element row, stops feeding the recording medium D2 and drives the recording head HD to record through the ink ribbon IR on the recording medium D2 in a main scanning direction while driving the carriage moving mechanism CH to move the carriage CA in that direction.
  • the control unit CP judges whether a recording operation is for the line of two lines before the time to cut the second recording medium D2. In the case of not recording on the line of two lines before a cutting time, the control unit CP drives the roller members JR1 and JR2 to feed the top end of the recording medium D2 by the length L1.
  • control unit CP drives, after the recording operation on the line, to feed the recording medium D2 by the feeding amount L3 which is less than the length L1 of the heating element row.
  • L4 remaining amount
  • the judgement of the control unit CP as to whether the current recording is for the line of two lines before the time to cut the second recording medium D2 depends on only the positional relation between the cutting unit KC and the recording head HD and, therefore, the recording medium D2 may be fed by the cutting unit CK driven after the recording of other lines than the line of two lines before the cutting time.
  • the cutting unit CK driven after the recording of other lines than the line of two lines before the cutting time.
  • it may be constructed so as to detect in advance the feeding amount more than a length corresponding to the backlash and regulate the feeding amount in feeding the recording medium D2 by the remaining amount.
  • the carriage CA can mount, on its mounting surface, selectively any one of the tape cassette TC accommodating the first recording medium D1 and the ink ribbon IR and others (see Figs. 2, 5, and 7) and the ink cassette RC accommodating only the ink ribbon IR (see Fig. 8).
  • a step motor SL (see Figs. 3 and 6) is mounted on the back side of the carriage CA.
  • This step motor SL is used for feeding the ink ribbon IR and the like accommodated in the tape cassette TC mounted on the carriage CA and for making the recording head HD press the second recording medium D2 or release from the same during a recording processing in the wide station WS.
  • the step motor SL is used as a driving power source for two purposes in order to effectively utilize the driving power of the step motor SL.
  • the recording head HD is mounted on the lower side of the carriage CA and, on its recording surface, is provided with a plurality of heating elements arranged in a row with a predetermined length (corresponding to a printing width L1 shown in Figs. 4(a) and 4(b)), the heating elements being able to heat per dot.
  • the tape feeding mechanism using the driving power of the step motor SL feeds the first recording medium (tape) D1 and others accommodated in the cassette TC mounted on the carriage CA toward the recording surface of the recording head HD in a direction orthogonal to the row of the heating elements.
  • the heating elements melt ink of the ink ribbon IR to make the ink adhere per dot to the first recording medium D1.
  • the tape cassette TC is, as shown in Fig. 7, constructed of a substantially rectangular cassette case which accommodates the first recording medium D1 to be used for a recording process in the tape station TS and the ink ribbon IR.
  • the ribbon cassette RC is, as shown in Fig. 8, constructed of a substantially rectangular cassette case which accommodates only the ink ribbon IR to be used in the wide station WS, without any recording medium, differently from the tape cassette TC.
  • the tape cassette TC accommodates the first recording medium D1 formed of transparent tape and the like having a small width, the ink ribbon IR used for printing on the first recording medium D1, and a double-sided adhesive tape YT to be adhered to the back of the printed recording medium D1, those being wound on reels TC1, TC2, and TC3 respectively as shown in Figs. 5 and 7. It is also provided with a reel TC4 for winding the used ink ribbon IR onto.
  • the unused ink ribbon IR wound on the reel TC2 is drawn therefrom and put on the first recording medium D1, and then fed into an open portion TC5 to pass between the recording head HD and the first platen P1. After that, the ink ribbon IR is separated from the first recording medium D1, and wound onto the reel TC4 driven by the step motor SL.
  • a cam member PC4a provided on the surface of the carriage CA is inserted in the reel TC4 of the tape cassette TC mounted on the carriage CA, and a driving cam follower TC4b is integrally fitted in the inside of the reel TC4, engaging with the cam member PC4a.
  • the reel TC4 Under the engagement of the driving cam follower TC4b and the cam member PC4a, the reel TC4 receives the driving power of the step motor SL through the gear train which will be described later, winding the used ink ribbon IR thereon.
  • the double-sided adhesive tape YT is accommodated in the tape cassette TC, which is wound on the reel TC3 with a releasable paper provided on the outside thereof.
  • the double-sided adhesive tape YT drawn from the reel TC3 is made to pass between a tape driving roller TC6 and a joint roller P3 thereby to adhere an adhesive surface of the tape YT on which no releasable paper is provided to the first recording medium D1.
  • the first recording medium D1 wound on the reel TC1 and drawn therefrom is fed between a pair of sensors SE for detecting a terminal end and a color of the medium D1 of the tape cassette TC and the ink ribbon IR of the ribbon cassette RC and via a guide pin TB1 into the opening portion TC5 of the tape cassette TC. Then, the first recording medium D1 is attached with the double-sided adhesive tape YT while passing between the tape driving roller TC6 rotatably disposed at a lower position in one side of the tape cassette TC, which is made to rotate by the driving power of the step motor SL, and the roller P3 disposed opposite to the roller TC6. The first recording medium D1 is discharged out of the tape cassette TC and then the main frame 2. At this time, the double-sided adhesive tape YT is adhered to the first recording medium D1 between both rollers TC6 and P3.
  • the roller P3 is supported in parallel with a first platen P1 on a roller holder LD.
  • This roller holder LD can make the roller P3 press against or separate from the roller TC6, and the first platen P1 press against or separate from the recording head HD at the same time. Since the platen P1 is required to be rotatable in order to feed the recording medium D1, a cylindrical platen is preferably used.
  • the tape driving roller TC6 is provided with a through hole TC8 as shown in Fig. 7, in which a cam follower TC9 is formed.
  • a cam member PC6b (see Fig. 9) formed on the surface side of the carriage CA is inserted in the through hole 8
  • the cam member PC6b is engaged with the cam follower TC9.
  • a cam member PC3a formed on the surface side of the carriage CA is inserted in the reel TC3.
  • This reel TC3 is, however, provided therein with no cam follower rotatable integrally with the reel TC3, so that the reel TC3 only idles, not participating in the feeding of the double-sided adhesive tape Yt.
  • the ribbon cassette RC used for recording character images on a surface D2b (see Fig. 4(b)) of the second recording medium D2 during a recording process in the wide station WS accommodates a reel RC1 for winding thereon an unused part of ink ribbon and a reel RC2 for winding thereon a used part of the ink ribbon.
  • the ink ribbon IR drawn from the reel RC1 is passed between the sensors SE, and is fed to an open portion RC3 of the ribbon cassette RC via a guide member RB1 (see Fig. 8), finally is wound on the reel RC2 via a guide member RB2.
  • the cam members PC4a and PC6b both formed on the surface of the carriage CA are inserted into reels RC4 and RC5 respectively.
  • These reels RC4 and RC5 of the ribbon cassette RC are not provided with any cam follower being rotatable integrally with the reels RC4 and RC5. Accordingly, the cam member PC4a and the tape driving roller TC6 only idle in receiving the driving power of the step motor SL, providing no influence on the feeding of the ink ribbon IR. There is no necessary to especially stop driving the cam member PC4a and the roller TC6.
  • the color ink ribbon IR in the ribbon cassette RC is applied thereon with a plurality of inks, for example, Cyan (C), Magenta (M), Yellow (Y), etc. by a predetermined length each, namely by a recording area of a line L2 (see Fig. 4(b)), which are repeatedly arranged in that order.
  • This is to make the recording head HD moving in the main scanning direction record on the second recording medium D2 with a single color by one line L2 through a part of the ink ribbon IR having any one color among magenta, cyan, and yellow in one line L2 length, and besides, with a mixed color by one line L2 through several parts of the ink ribbon IR.
  • the recording medium D2 is recorded by one line through a part of the ink ribbon IR having any one color among magenta, cyan, and yellow, and then on the same line through a different part of the ink ribbon IR having a different color and, if necessary, on the same line through a further different part of the ink ribbon IR.
  • the images with a mixed color of cyan, magenta, and yellow such as red, blue, etc. can be recorded on the second recording medium D2.
  • Deference points between the tape cassette TC and the ribbon cassette RC are in that the position of the reels TC2 and RC1 for winding thereon unused ink ribbon and the position of the reels TC4 and RC2 for winding thereon used ink ribbon in addition to whether the double-sided adhesive tape YT and the first recording medium D1 are accommodated or not.
  • the position of the reel TC1 of the tape cassette TC corresponds to the position of the reel RC1 of the ribbon cassette RC
  • the position of the reel TC3 for the double-sided adhesive tape YT corresponds to the reel RC2 of the ribbon cassette RC.
  • the tape cassette TC for a single color recording accommodates the ink ribbon IR of a single color, having a length corresponding to that of the first recording medium (tape) D1
  • the ribbon cassette RC for a multicolor recording is needed to accommodate the ink ribbon having a length three times or more as the length of a recording area because the ink ribbon IR is required to have three parts each having any one color of cyan, magenta, yellow, etc., for example, by a predetermined length each (namely, by one line). If the ribbon cassette RC is used for a single color recording, it is not necessary to apply three colors such as cyan, magenta, and yellow on the ink ribbon IR.
