Description

  The present invention relates to a printer apparatus provided with a cutter for cutting recording paper, and more particularly to a printer apparatus provided with a chip storage unit for loading and storing cut chips.

  2. Description of the Related Art Conventionally, as one of printer apparatuses, there is known a method of performing printing on a roll-shaped recording paper, and then separating the printed material from the recording paper to obtain a desired printed material. As an example of such a printer apparatus, there is a thermal transfer recording type printing configuration in which an ink ribbon ink as shown in FIG. 23 is thermally transferred onto a sheet to record an image. In the printer apparatus 100, roll-shaped recording paper 101 is used as a recording medium, and yellow, magenta, and cyan pigments are printed on the ink ribbon 102 in advance. The roll-shaped recording paper 101 and the ink ribbon 102 are conveyed while applying an arbitrary pulse current to the heating resistor formed on the thermal head 105 attached to the heat radiating member 106 and printed on the ink ribbon. An image is formed by thermally transferring ink to the recording paper 101. In addition, an overcoat material for preventing image deterioration is applied to the ink ribbon as necessary.

  With respect to a series of printing processes of the thermal transfer recording type printer apparatus 100, first, the roll-shaped recording paper 101 is pulled out to a predetermined amount on the conveyance path by power from a drive source (not shown), and the conveyance roller 109 and the pinch roller. 110 nips the recording paper 101. Here, the pinch roller 110 presses the recording paper 101 against the conveying roller 109. The recording paper 101 is conveyed to a printing area via a decurling roller 112 in order to reduce curling caused by being wound in a roll. In this configuration, the supply side bobbin 104 of the ink ribbon 102 is set downstream of the thermal head 105 in the recording paper conveyance direction, and the take-up side bobbin 103 of the ink ribbon 102 is further upstream of the thermal head 105 in the recording paper conveyance direction. Therefore, when the ink of the ink ribbon 103 is thermally transferred to the roll-shaped recording paper 101, printing is performed while the recording paper is wound up upstream in the recording paper conveyance direction. In the case of such a configuration, the recording paper 101 is once pulled out from the roll-shaped recording paper 101 to a position where the recording paper writing position is arranged downstream of the thermal head heating resistor arrangement position in the recording paper conveyance direction, From this state, printing on the roll-shaped recording paper 101 is started.

  When the desired printing is completed, the writing end position of the recording paper is conveyed to the cutting position of the cutter mechanism 108 by the driving source, and the roll-shaped recording paper 101 and the printed matter are cut. Thereafter, the generated printed matter is discharged out of the casing by the paper discharge roller 111.

  In recent years, there has been a demand for a print product having no margin in the periphery of the generated print product. As one method for generating such a printed matter, when cutting the roll-shaped recording paper 101 and the printed matter, the printed screen side is cut from the boundary between the printed screen and the unprinted screen, There is known a method of further cutting and discharging the excess area remaining on the roll-shaped recording paper 101 side as chips after generating a non-printed product.

  When the above method is adopted, it is desirable to discharge chips to a place different from the place from which the printed material is discharged, and a structure for discharging and storing the chips and preventing the stored chips from being scattered around. Further, it is necessary to have means for detecting the loading of the stored chips, detection means for determining whether or not the member for storing the chips is disposed at an arbitrary position, and the like.

  As a method for setting a member for storing chips as described above, and for storing chips and detecting the load amount, for example, in Patent Document 1, the accumulated load amount of chips is stored in a nonvolatile storage element, and the total amount of chips is A warning is given to the user when the prescribed amount is exceeded. Further, for example, in Patent Document 2, a chip pressing member for preventing scattering of chips is set, and before the recording paper is cut by the cutter mechanism, the pressing member is retracted to a position where it does not interfere with falling chips, and after cutting By displacing to the chip pressing position, it is configured so that the chip pressing member does not hinder the storage of the chip into the storage member. Furthermore, in Patent Document 2, it is determined whether or not to warn the user by detecting whether or not the load is full in the load amount detection method.

JP 2004-182422 A JP 2006-192654 A

  However, in the prior art disclosed in Patent Document 1 described above, the stored chips remain unstablely loaded in the storage member, and the stored chips are moved into the casing when the bottom surface is shaken when carrying the casing. May not only cause trouble in the cutting operation and printing operation of the recording paper, but also cause a failure of the printer. Moreover, in the prior art disclosed in Patent Document 2 described above, it is necessary to retract the chip pressing member from the discharge path before cutting the chips, which may be an obstacle to further downsizing the apparatus. In addition, since the load detection method detects whether the load is full or not, for example, if you want to obtain multiple prints in succession, the chips in the storage member will become full during continuous printing. Then, once printing is interrupted, it is necessary to watch carefully during printing in order to perform printing without delay. Advance what extent the chip accommodating member before performing the printing in the prior art, possible to determine whether the chip is accommodated is difficult.

  The present invention is for solving the above-mentioned problems, the purpose of which is to achieve chip loading and storage, prevention of chip scattering in the storage member, and detection of the load amount with a simple structure, and It is to provide a compact chip storage device.

  In order to achieve the above object, a first invention according to the present application provides a chip storage for loading and storing cut chips in a printer having a cutter mechanism that is driven by a driving force from a driving source and cuts a recording medium. And a lid that covers a part of the chip accommodating portion and is configured to be opened and closed by driving the cutter mechanism, and is formed in the chip accommodating portion and presses the chips in conjunction with the opening and closing operation of the lid And a chip pressing member that is displaceable between a pressing position to be retracted and a retreat position in which the chip is retracted from the path in which the chip is accommodated in the accommodating portion, and the pressing member generates power from the opening and closing operation of the lid. The receiving position is set between a position where the chip is pressed and a fulcrum held by the chip container, and the movable range of the pressing member is set within the open / close range of the chip container and the lid. Characterize

  2nd invention which concerns on this application detects the said chip accommodation amount of the said chip accommodating part by changing the position which presses the said chip of the said press member.

  The third invention according to the present application is characterized in that the chip accommodating path to the chip accommodating portion is formed by opening and closing the lid.

  A fourth invention according to the present application is characterized by comprising a biasing means for biasing the lid in the closing direction.

  A fifth invention according to the present application is characterized in that the pressing member is formed entirely or partially by a conductive member.

  According to a sixth aspect of the present application, a detection unit that detects a position where the pressing member presses the chips is formed at a position facing the conductive portion of the pressing member and being able to contact the pressing member. The chip accommodation amount is detected by a change in position.

  A seventh invention according to the present application is characterized in that a part of the detection unit is a variable resistor in which a conductive paste is formed on an insulating substrate.

  The eighth invention according to the present application is characterized by having a notifying means for notifying the detection result of the detecting section.

  According to the present invention, since the movable range of the pressing member is set within the open / close range of the chip accommodating portion and the lid, the functions of the chip accommodating, the pressing into the accommodating portion, the detection of the loading amount, and the like are satisfied. The enlargement of the required area can be reduced.

  Further, according to the present invention, the entire pressing member or a part of the pressing member is formed of a conductive member, and the position where the chip is pressed to a position where the pressing member faces the conductive portion and can be contacted is detected. Since the detection unit is formed and the amount of chips contained is detected by the change in the pressing position, the user can easily check how much chips are contained in the member storage unit before printing. I can do it.

  Hereinafter, a preferred embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 shows an outline of a chip accommodating portion embodying the present invention. FIG. 2 schematically shows a thermal transfer recording printer embodying the present invention.

  According to FIGS. 1 and 2, the printer 1 uses a roll-like recording paper 2 as a recording medium, and yellow, magenta, and cyan pigments are printed on the ink ribbon 3 in advance. While applying an arbitrary pulse current to a heating resistor (not shown) formed on the thermal head 4 attached to the heat radiating member 41, the roll-shaped recording paper 2 and the ink ribbon 3 are transported to form an ink ribbon. An image is formed by thermally transferring the ink printed on the paper to the roll-shaped recording paper 2. In addition, an overcoat material for preventing image deterioration is applied to the ink ribbon as necessary.

  With respect to a series of printing processes of the thermal transfer recording type printer apparatus 1 as described above, first, the roll-shaped recording paper 2 is pulled out onto the conveyance path by a power from a drive source (not shown), and the conveyance roller 6 and the pinch roller 7 nips the roll-shaped recording paper 2. Here, the pinch roller 7 presses the roll-shaped recording paper 2 against the conveying roller 6. In order to reduce curling caused by the roll-shaped recording paper 2 being wound around the core, a decurling roller 11 is set in the conveyance path, and is conveyed to the printing area via this. In this embodiment, the supply-side bobbin 31 for the ink ribbon 3 is set downstream of the thermal head 4 in the recording paper transport direction, and the take-up bobbin 32 for the ink ribbon 3 is further upstream of the thermal head 4 in the recording paper transport direction. Is set, and when the ink of the ink ribbon 3 is thermally transferred to the roll-shaped recording paper 2, printing is performed while winding the recording paper upstream in the recording paper conveyance direction. In the case of such a configuration, the recording paper is once pulled out from the roll-shaped recording paper 2 to a position where the recording paper writing position is arranged at the downstream side in the recording paper conveyance direction from the arrangement position of the heating resistor of the thermal head, From this state, printing on the roll recording paper 2 is started.

  When the desired printing is completed, the writing end position of the roll-shaped recording paper 2 is conveyed to the cutting position of the cutter mechanism 9 by the drive source, and the roll-shaped recording paper 2 and the printed material are cut. Thereafter, the generated printed matter is discharged out of the casing by the paper discharge roller 10.

  In order to form a print without a border, first, when the roll-shaped recording paper 2 and the print are cut, the print screen side is cut from the boundary between the print screen and the unprinted screen. Then, after the print product having no edge is generated, in order to process the excess area remaining on the roll-shaped recording paper 2 side as chips, the roll-shaped recording paper 2 is further moved to the downstream side in the conveyance direction by a predetermined amount, at least the conveyance roller 10. Conveys the chips to a distance at which they can be nipped, then cuts the chips and discharges them to the chip container.

  In the present embodiment, by following the above-described process, the chips are discharged to the chip accommodating portion inside the housing, and a printed product without a border is formed.

  Next, the structure of the chip accommodating part 8 is demonstrated based on FIGS. 3-9.

  FIG. 3 is a development view of the chip accommodating portion 8. FIG. 4 is a perspective view showing a state in which the chip accommodating portion 8 and its components are combined. In the present embodiment, the chip accommodating portion 8 includes a chip accommodating lid 81, a pressing member 82, a coil spring 83 for biasing the lid, and a torsion spring 84 for biasing the pressing member to form a chip accommodating structure. Yes.

  The pressing member 82 is inserted into the chip accommodating portion 8 in a state where the support shaft 821 is inserted into the fulcrum opening 803 formed in the chip accommodating portion 8 and the torsion spring 84 is incorporated in the spring hooking portion 824 in advance. The urging force of the torsion spring 84 is in a state of being urged in advance toward the chip housing portion bottom surface side. Moreover, these assembly | attachment is performed in the space between the chip accommodating part 8 side surface and the partition wall 805. FIG. Thereby, the partition wall 805 has the role which partitions off the area | region which accommodates a chip | tip, and the area | region where the driving force transmission part of a chip accommodation cover and a press member is arrange | positioned.

  Next, the chip accommodating lid 81 is attached to the chip accommodating part 8 by sliding the slide part 812 in accordance with the slide groove 804 formed in the chip accommodating part 8. Further, the chip storage lid 81 is configured to be a chip storage portion by assembling a coil spring 83 having both ends fixed by a spring hook portion 813 formed on the pressing member holding portion 811 and a spring hook portion 807 formed on the pressing member 8 side. It is in a state of being biased toward the bottom side. From this state, the chip storage lid 81 has a structure capable of translational movement so as to open and close the opening 806 formed in the chip storage portion 8, and an external force is applied so that the chip storage lid 81 opens the opening 806. Then, when the external force is released, the chip accommodating lid 81 is moved by the action of the coil spring 83 until the opening 806 is in the closed position.

  Further, the pressing member 82 and the chip housing lid 81 are assembled while maintaining the relationship in which the transmission pin 822 is inserted inside the U-shaped inside of the pressing member holding portion 811. As described above, since the pressing member is pre-biased by the torsion spring 84 toward the chip housing portion bottom surface, an external force is applied to the chip housing lid, and the chip housing lid 81 moves the opening 806 to the open position. In this case, the pressing member holding portion 811 is configured to push the transmission pin 822 upward, and the pressing member 82 rotates in the direction opposite to the urging direction with the support shaft 821 as the center of rotation. At this time, the free end 823 formed on the pressing member 82 also rotates about the support shaft 821, but the partition wall 805 is provided with a free end opening 802 along the rotation locus of the free end 823. Therefore, the rotation operation of the pressing member 82 has a structure in which the rotation is not hindered by the interference of the chip accommodating portion 8 between the pressing position and the operating range in the opening direction.

  When the external force applied to the chip housing lid 81 is released, the force that pushes the pressing member holding portion 811 upward by the transmission pin 822 is also released at the same time. A series of operations of rotating to the bottom surface side of the accommodating portion 8 and moving to the pressing position is performed.

  FIG. 5 is a perspective view of the cutter unit 9. 6 to 9 are views showing the operations of the chip storage lid 81 and the pressing member 82 that operate in conjunction with the movement of the movable blade 91. The cutter unit 9 is formed so that the movable blade 91 and the fixed blade 92 are disposed. The movable blade 91 is held so as to be movable in the A / B direction of FIG. 6 by receiving power from the drive source. A pin 911 is formed on the movable blade 91.

  The chip accommodating portion 8 is incorporated into the printer apparatus 1 from a position where the pin 911 is inserted into the pin insertion groove 801, and stops at a position where the pin insertion groove 801 and the pin 911 face each other. As a result, the movable blade 91 moves in the A / B direction in response to power from the drive source, so that the pin 911 serves as a drive source that opens and closes the chip storage lid 81. That is, when the movable blade 91 moves in the direction A of FIG. 8 to the position where the roll-shaped recording paper 2 is cut as shown in FIGS. 8 and 9, the chip storage lid 81 moves in the opening direction. The pressing member 82 also rotates in the direction opposite to the urging direction. Further, when the movable blade 91 moves in the B direction to a position where the movable recording sheet 2 is retracted from the conveyance path, the chip accommodating lid 81 moves in the closing direction, whereby the pressing member 82 also moves to the bottom surface of the chip accommodating portion 8. It will move to the pressing position to the side.

  As described above, the chip accommodating portion 8 performs the opening / closing operation of the chip accommodating lid 81 and the raising / lowering operation of the pressing member 82 in conjunction with the cutting operation of the movable blade 91. In this embodiment, the opening / closing operation of the chip storage lid 81 is performed by sliding upward substantially from the position where the chip storage portion 8 is arranged, and the operating range of the pressing member 82 is the movable of the chip storage portion 8 and the chip storage lid 81. Since it operates within the range, the operating range is expanded to other areas before the chips are discharged into the chip accommodating portion 8, and the placement position of the chip accommodating portion 8 is excessively restricted, or printing is performed. Problems such as obstructing functions are reduced.

  Next, the operation of the movable blade 91 and the chip storage portion 8 when generating and discharging chips in the printer apparatus 1 will be described below.

  FIG. 10 is a diagram showing the printed area and the unprinted area of the roll-shaped recording paper, and the boundary between them. As described above, in order to obtain a borderless print, the printer apparatus 1 first completes a desired print, and then the writing end position of the roll-shaped recording paper 2 by the drive source, the print boundary 23 shown in FIG. Further, the roll-shaped recording paper 2 is conveyed until the position where the L1 has moved to the printing area 21 side reaches the cutting position of the cutter mechanism 9, and the roll-shaped recording paper 2 and the printed matter are cut. This L1 prints a distance that can guarantee that an unprinted area of the roll-shaped recording paper 2 will not be cut when a printed matter is generated even if the skew amount of the roll-shaped recording paper 2 or a conveyance error is taken into account. The distance is secured from the boundary portion 23. Thereafter, the generated printed matter is discharged out of the casing by the paper discharge roller 10.

  After discharging the printed matter, the roll-shaped recording paper 2 is further conveyed by a distance L2 downstream in the conveyance direction in order to treat the region including L1 remaining on the roll-shaped recording paper 2 side as chips. In the present embodiment, L2 indicates a distance at which at least the paper discharge roller 10 can nip chips. Thereafter, the roll-shaped recording paper 2 is cut at the chip cutting position 25 while the roll-shaped recording paper 2 is nipped by the paper discharge roller 10, and the chips 20 are generated. The chip 20 is discharged to the chip container by the subsequent operation of the printer device. In order to discharge the cut and generated chips 20 to the chip storage unit 8, the printer apparatus 1 performs the operations expressed in FIGS. 11 to 16.

  First, FIG. 11 shows a cross-sectional view in a state where the movable blade 91 cuts the roll-shaped recording paper 2 at the chip cutting position 25 by the power from the drive source. At this time, the chip storage lid 81 moves in the opening direction so as to form the opening 806 in conjunction with the movement of the movable blade. Further, the pressing member 82 is rotated in the direction opposite to the urging direction of the torsion spring 84 because the rotating force about the support shaft 821 is applied from the pressing member holding portion 811 formed on the chip housing lid 81 to the transmission pin 822. As a result, the pressing member rotates to the position where the free end 823 retracts from the discharge path when the chips 20 are stored in the chip storage member 8. The moving amount of the movable blade 91 at this time is set so that the chip accommodating lid 82 forms the opening 806 and moves in a predetermined amount in the opening direction to a position where it does not interfere with the fixed blade 92. Next, as shown in FIG. 12, the paper discharge roller 10 conveys the chips 20 by a predetermined amount and downstream in the roll recording sheet conveyance direction to a position where the rear end of the chips is close to the opening 806. Thereafter, as shown in FIG. 13, the paper discharge roller 10 performs return driving to the upstream side in the roll recording paper conveyance direction, and performs an operation of sending the chips 20 into the opening 806. At this time, the amount of rotation of the paper discharge roller 10 is given in advance a fixed amount of movement for both the amount of conveyance downstream in the conveyance direction of the roll-shaped recording paper and the amount of return conveyance upstream of the same.

  At this time, as described above, since the free end portion 823 of the pressing member is retracted to a position where it does not interfere with the chip 20, the chip 20 can enter the opening 806 without delay. Then, the chips 20 are placed on the bottom surface of the chip accommodating portion 8 as shown in FIG. The movable blade 91 is driven from the cutting position to the standby position by a driving source, and the movement of the movable blade 91 causes the chip housing lid 81 to receive a spring biasing force from the coil spring 83 to close the opening 806. Moving. Further, since the pressing force of the pressing member 82 in the direction of opening the opening 806 from the pressing member holding portion 811 to the transmission pin 822 is released, the pressing member 82 is moved from the paper discharge path retracted position by the spring biasing force of the pressing member biasing spring. Will move. By a series of operations of the movable blade 91, the chip storage lid 81, and the pressing member 82, the chip 20 can be generated from the roll-shaped recording paper 2 and can be stored in the chip storage unit 8. By repeating this series of operations, as shown in FIGS. 15 and 16, the pressing position where the chips 20 are placed and stacked in the chip accommodating portion 8 and the free end 823 of the pressing member 82 presses the chips 20 is as follows. It will be displaced with the load of the chips 20.

  In the present embodiment, by detecting the pressing position of the free end 823 of the pressing member 82 that fluctuates with the above-described loading amount, it is possible to detect the loading amount of the chips 20 loaded in the chip container 8. I can do it. Hereinafter, a description will be given based on FIGS. 17 to 22.

  FIG. 17 is a perspective view showing the configuration of the detection member 13 for detecting the load amount of the chips 20 in the present embodiment. The detection member 13 mainly includes a fixed contact portion 131, a variable contact portion 132, and a wiring joint portion 133. In this embodiment, the detection member 13 employs a configuration in which, for example, a phenolic resin containing carbon powder is printed on a printed wiring board having a paper phenolic resin copper-clad laminate as a base material and printed on the contact portion. The detection member is soldered to a wiring material such as a conductive wire at a wiring joint 133 and connected to a signal processing unit in which an integrated circuit or an arithmetic circuit is incorporated. FIG. 18 is a side perspective view of the chip accommodating portion 8. A free end opening 802 is formed on the side surface of the chip accommodating portion 8, and a free end side protruding portion 826 formed in a shape partially protruding from the free end 823 protrudes from the opening. Further, a support shaft side protruding portion 825 is formed on the support shaft 821 of the pressing member 82 and protrudes from the opening of the chip accommodating portion 8. In this embodiment, among the pressing member 82, the free end side protruding portion 826, the support shaft side protruding portion 825, and the region including these are electrically conductive members such as carbon, silver, nickel, tin, And a member formed of a thermosetting resin containing a conductive powder such as an alloy thereof, and so on, has a certain conductivity between the support shaft side protruding portion 825 and the free end side protruding portion. Yes. Further, as described above, the pressing position of the free end 823 that presses the chip 20 varies as the pressing member 82 places and loads the chip 20 in the chip storage unit 8. And the variable contact part 132 formed in the detection member 13 is formed in the shape along the displacement locus | trajectory of the free end part 823 of the pressing member 82 which fluctuates.

  As for the arrangement position of the detection member 13 in the printer apparatus 1, as shown in FIGS. 19 and 20, the chip accommodating part on the side from which the support shaft side detection part 825 and the free end side protrusion part 826 in the printer apparatus protrude. The detection member 13 is arranged at a position facing the eight side surfaces, and when the chip accommodating portion 8 is inserted into the printer apparatus 1, the fixed contact portion 131 and the free end side protruding portion 826 are arranged on the supporting shaft side protruding portion 825. The variable contact portion 132 is fixed at a position where it contacts.
