Description

  The present invention relates to a printing apparatus that can selectively use two power sources, an AC power source and a battery power source, and in particular, when the AC power source is used by changing the printing control when using the AC power source and the battery power source. The present invention relates to a thermal transfer type printing apparatus capable of performing high-speed printing for a long time when using a battery power source.

  Many portable electronic devices have come to be used because of their convenience. Many of such portable electronic devices employ a dual power supply system of an AC power source and a battery power source so that they can be used anywhere.

  There are no exceptions in the printing apparatus. For example, many printing apparatuses connected to a portable communication terminal apparatus and label printers using a label sheet as a printing medium can be driven by two power sources, an AC power source and a battery power source. .

  In such a dual power supply type electronic device, the capacity of a battery pack mounted or externally attached is limited due to a demand for a reduction in device size and weight. In such a device, when a battery power source is used, the operation of the device is stopped to prevent malfunction of the device when the voltage of the battery power source becomes a predetermined value or less. In particular, in the case of a printing apparatus, during printing operation, since the print head must be driven while moving the printing medium in the printing direction, a large amount of electric power is consumed. As a result, the time required to reach the lowest voltage that guarantees the normal operation of the apparatus is shortened, and as a result, the number of prints that can be guaranteed is greatly reduced.

  For this reason, in the conventional dual-power-source printing apparatus, various devices have been conventionally made in order to extend the usage time during battery operation as much as possible.

As an example of such a printing apparatus, for example, when the power consumption varies greatly depending on the black rate of the print data as in a thermal transfer printer, when using battery power, white data is used at a constant rate according to the black rate. (E.g., Patent Document 1), or setting the upper limit to the maximum use current when the heating elements constituting the thermal transfer thermal head are energized at the same time and driving at constant current ( For example, Patent Document 2), and further, when the battery voltage is lower than a predetermined position in a thermal ink jet printer, various types of forced energy application are reduced to a low energy printing mode (for example, Patent Document 3). The prior art is known.
Japanese Patent Laid-Open No. 5-124264 Japanese Patent Application Laid-Open No. 2001-232843 Japanese Patent Laid-Open No. 5-124264

  However, power saving measures at the time of battery power operation in such a conventional printing device can extend the operating time at the time of battery operation by reducing the peak value of current consumption, This restricts the inherent printing performance and degrades the printing quality. Furthermore, the countermeasure described in Patent Document 1 requires a significant change in the control program when the AC power source is driven and when the battery is operated, which complicates the program system in the apparatus. Further, the methods described in Patent Documents 2 and 3 require hardware such as a constant current drive circuit and a voltage control circuit, and software for selectively driving the hardware.

  The present invention has been made in view of the problems of the prior art, and in a two-power-supply type printing apparatus, the print quality is not deteriorated even when the battery is operated, and the control program and the control circuit are complicated. It is another object of the present invention to provide a printing apparatus in which the number of printable sheets is increased by reducing the maximum power consumption of the apparatus during battery operation.

  For this reason, the present application relates to a printing device that can be operated by either an AC power source or a battery power source, a printing unit that prints characters or figures on a printing medium, and a printing direction of either the printing medium or the printing unit. Moving means for moving the power supply, power supply detection means for detecting whether the power supply is an AC power supply or a battery power supply and outputting a power type signal, and a control means for controlling the printing means and the moving means. The control means switches the period of the print control signal for driving and controlling the print head constituting the printing means in accordance with the power supply type signal, and changes the moving speed by the movement means to the period of the print control signal. The printing apparatus is characterized in that the speed is controlled in synchronism with the printing speed.

  As a result, although the printing speed is somewhat reduced, it is possible to extend the operable time of the printing apparatus during battery operation without degrading the printing performance of the printing apparatus.

  Here, when the power supply type signal indicates AC power, the control means outputs a print control signal having a first cycle, and when the power supply type signal indicates battery power, the control unit starts from the first cycle. A print control signal having a long second cycle is output.

  The print control signal is a print strobe signal that defines an energization cycle and an energization time of the print head.

  Further, the moving means is configured to move a label sheet as the printing medium in the printing direction with respect to the printing means arranged at a predetermined position in the apparatus.

  The present invention is a dual-power-source printing apparatus that does not deteriorate the printing quality inherent to the printing apparatus even when the battery is operated, and does not complicate the control program or control circuit. By reducing the power consumption, it was possible to increase the number of printable sheets.

  Hereinafter, a case where an embodiment of a display device according to the present invention is applied to a label printer (label printer) will be described in detail with reference to the drawings.

  FIG. 1 shows an appearance of a label printing apparatus 1 to which the present invention is applied. Here, FIG. 1A shows an upper front perspective view of the label printing apparatus 1, and FIG. 1B shows a rear perspective view. In FIG. 1, when the operation start switch 6 is turned on, the label printing apparatus 1 starts operating. When a character including a series of numbers and symbols is input by the input means (key input unit) 3, the input character is displayed on the display panel 2. 1 is printed by an internal printing means (not shown).

  Printing is performed on a predetermined label sheet inserted in the label sheet insertion port 4 provided on the front side of the apparatus, and the printed label sheet is discharged from the label sheet discharge port 5 provided on the back side of the apparatus. Is done. Note that the print medium to be printed in this apparatus may be in the form of a roll or strip, and may be configured to be stored inside the apparatus main body.

  The key input unit 3 constituting the input means includes a plurality of alphabetic keys, numeric keys, kana character keys, function keys (function keys), space input keys, and the like. These keys can have a plurality of types of key input functions with one key by operating a shift key (function key) or the like. Similarly to a personal computer, the character data input by an alphabetic key, a kana character key, or the like has a function of being converted into a kanji character by operating a predetermined function key, similar to a word processor or the like.

  The display panel 2 displays input characters, characters converted to kanji based on the input character data, and the like. It is also possible to display characters and symbols for explaining operation guidance and functions for assisting the operation of the operator. In the case of a label printing apparatus, the display panel 2 is usually a liquid crystal display, but may be a display panel of another type such as a plasma spray. Unlike the display device such as a personal computer, the size of the display panel 2 usually has a display area of only a few lines because of its functional necessity and size restrictions. This is because it is sufficient for the display area of the display panel 2 to correspond to the size of the label to be printed.

  This printing apparatus adopts a dual power supply system using an AC commercial power supply and a battery power supply. Therefore, as shown in FIG. 1A, a power input terminal 120 for receiving an output terminal of an external AC adapter (not shown) is provided on the left side of the printing apparatus. Next to the power input terminal 120, a USB cable terminal 121 for connecting to an external device such as a PC is provided. As described above, in this embodiment, the AC adapter is externally attached, but it goes without saying that the AC adapter may be built in the apparatus and the power cord may be drawn from the apparatus main body.

  FIG. 2 is a bottom perspective view of the printing apparatus. As shown in the figure, a battery cover 122 is provided on the bottom surface. When the battery cover 122 is removed, a battery storage portion 123 for storing a battery is provided inside the bottom surface. In the present embodiment, six AA batteries are connected in series. The battery having such a configuration may be packaged and incorporated into the apparatus as a single battery package.

  FIG. 3 is a block diagram showing the basic configuration of the label printing apparatus.

  The printing apparatus includes a key input unit 3, a display panel 2, printing units 101 to 104, and a control unit (FIG. 3) for controlling them uniformly.

  The control means includes a control unit 115 (CPU), a ROM 116 for storing various processing programs, dictionary data for kana-kanji conversion, and fixed data, a working memory, various counters, and an operator (user) data input. A RAM 117 that is a rewritable memory for storing such fixed data and the like, a display character generator ROM 118 and a print character generator ROM 119, and a power supply unit 21 and the like which will be described in detail later are included.

  The printing means 101 to 104 include a thermal head 101 as a print head, a head driving unit (circuit) 130 that applies a voltage to a heating element constituting the thermal head 101, and a carriage 103 on which the thermal head 101 is mounted. A carriage motor driving unit 131 for driving a carriage motor for moving in a direction orthogonal to the conveyance direction, a pair of carry-in rollers 105 (FIG. 4) and a pair of carry-out rollers for carrying a label sheet as a printing medium in the apparatus. 106 (FIG. 4), a transport motor 107 for driving the transport motor, a transport motor drive unit 108, a lift motor 111 for moving the thermal head to a position where it is pressed against and separated from the ink ribbon, and this lift motor 111 is driven. The thermal head elevating motor driving unit 112 and the label sheet are inserted. A sheet detection unit 132 and the ink ribbon is fused to the label sheet by the thermal head ribbon take-up detecting unit 133 for detecting that, and is composed of.

  The display panel 2 includes a display panel such as a liquid crystal panel and a display driving unit 134 for driving the display panel.

  Next, an example of the circuit configuration of the power detection means that detects whether the power supply in the present invention is an AC power supply or a battery power supply and outputs a power supply type signal will be described.

  As described above, the printing apparatus employs a dual power supply system using an AC commercial power supply and a battery power supply. The AC adapter 11 shown in FIG. 3 has a power cord (not shown), and is a power supply device that rectifies an AC commercial frequency power supply voltage (for example, AC 100 V / 50 Hz) and outputs DC 9 to 10 V at the rated time. The DC voltage output from the AC adapter passes through the coil constituting the relay 12. On the other hand, the battery 15 is connected to a terminal that is turned ON / OFF by the coil of the relay 12.

  This relay 12 is for automatically selecting a power supply. That is, when a DC voltage is output from the AC adapter 11, a current flows through the coil, so that the contact is attracted to the “NO” side and the power supply from the battery 15 side is disconnected. When no DC voltage is output from the AC adapter 11, no current flows through the coil. Therefore, the contact is returned to the “NC” side by the action of the spring in the relay 12, and power is supplied from the battery 15 side. It will be. The diode 13 is a backflow prevention diode 13 for preventing a current from flowing to the AC adapter 11 side when power is supplied from the battery 15 side. Reference numeral 20 denotes a protective circuit that protects the device when the electrodes of the dry battery are stored upside down.

  The output voltage of the AC adapter 11 is simultaneously input to the voltage detection circuit 16 and input to the control means. As a result, the control unit 115 detects that power is being supplied from the AC adapter.

  When power is supplied from either the AC adapter 11 or the battery 15, a power supply voltage is normally supplied to the power supply circuit 21 in the apparatus. However, for example, when the output voltage drops from the power supply side during battery operation, the FET 14 which is a switch for disconnecting the power supply side from the power supply circuit 21 in the apparatus is connected to the power supply side and the apparatus in the apparatus. Provided between the power supply circuits 21. For this reason, the DC input voltage input to the power supply circuit in the apparatus needs to be constantly monitored in the control apparatus, and the DC input voltage is obtained by dividing the voltage proportionally divided by the two resistors 18 and 19 into the control circuit. Is input.

  By the way, since the FET 14 needs to supply power to the immediate power supply circuit 21 when the power switch is turned on, the FET 14 becomes conductive when the input signal from the ON / OFF circuit 17 is at a low level (at the time of zero potential). ON), and when the input signal from the ON / OFF circuit 17 is at a high level, it is cut off (OFF).

  The power supply voltage 21 in the apparatus incorporates a DC / DC converter for generating another DC voltage required in the present printing apparatus from DC 9V which is a DC input voltage.

  The control means of the present invention further includes a plurality of clock signal generation means having different frequencies. An oscillation signal f1 having a stable frequency is generated by the combination of the crystal resonator 22 and the oscillation circuit 23, and the oscillation signal f1 is input to the counter circuit 24, whereby a plurality of frequencies that are integer multiples of the oscillation frequency f1 are generated. Clock signals f2, f3, f4, etc. are obtained.

  The control means selectively uses a plurality of clock signals of different frequencies obtained in this manner, so that a print strobe that defines the energization period and energization time of the thermal head 101 will be described in detail later. A signal and a timing signal that regulates the movement of the thermal head 101 in synchronization with the print strobe signal are generated.

  FIG. 4 is a cross-sectional view of the apparatus for explaining the main mechanism constituent means inside the printing apparatus, and FIG. 5 is a mechanism configuration diagram viewed from the bottom side of the apparatus.

  As described in the basic configuration of FIG. 3, the printing means constituting the present invention includes a thermal head 101 that applies heat to a belt-shaped ink ribbon coated with solid ink to melt the ink and adhere to the sheet surface, and printing. A platen 102 that presses the ink ribbon and the sheet between the thermal head 101 at a position, and a print carriage 103 that is attached to the thermal head 101 and moves in a direction perpendicular to the moving direction of the sheet to perform line printing on the sheet surface. And a ribbon cassette 104 that contains an ink ribbon and is detachably attached to the print carriage.

  Further, as moving means for moving a label sheet as a printing medium, a pair of carry-in rollers 105 that sends a sheet inserted from the sheet carry-in port to the print position, and a sheet printed at the print position is discharged from the sheet carry-out port. A carry-out roller pair 106, a conveyance motor 107 that drives each roller pair, and a drive transmission system 108 thereof are provided.

  Further, in FIG. 5, the carriage motor 109 and its drive system 110 for moving the print carriage in the direction orthogonal to the label sheet conveyance direction and winding the ink ribbon, and the position where the ink ribbon is pressed against the print surface of the label. An elevating motor 111 and its drive system 112 for elevating and lowering the thermal head 101 at a position to be separated are provided.

FIG. 6 shows an example of a flowchart of an initial process when the printer is turned on.
When the power switch of the apparatus is turned on (S1), it is checked whether the level of the DC input (see FIG. 3) is equal to or higher than a predetermined value (for example, 9V) (S2). Displays a warning that the input voltage is low on the display panel or the like (S3).

  When the DC input level is greater than or equal to a predetermined value, initial processing such as various counters and constants is performed (S4), and then a voltage detection circuit is used to detect whether the power source is an AC power source or a battery power source. 16 (see FIG. 3) is read whether the output signal is high level or low level (S5). If the output signal is high level, the AC power supply is turned on. .

  If it is determined that the AC power is turned on, it is set to “high-speed printing mode”. If it is determined that the AC power is not turned on and the battery power is activated, it is set to “low-speed printing mode”. To do. After setting the print mode. Printing processing in the set printing mode is performed (S8).

  When the printing process is completed and the power supply 6 of the apparatus is turned off (S9), parameters and data for various setting conditions for continuing to the next printing process are set in the RAM 117 (FIG. 3) (S10). The initial before the printing process is terminated.

  7 to 9 show an example of a printing operation flow performed based on the printing mode set to either the “high-speed printing mode” or the “low-speed printing mode” in the above-described initial processing. Although the difference between the high-speed printing mode and the low-speed printing mode will be described in detail later, there is no difference in the basic operation of the printing process described below.

  In FIG. 7, first, the label sheet is inserted until it hits the nip portion of the carry-in roller pair 105, the label sheet is set at a predetermined position, and the print execution key is pressed with the input key. ”(S11), the conveyance motor 107 is driven (S12), and the carry-in roller and the carry-out roller 106 rotate in the forward direction. Thereby, the label sheet is conveyed in the forward direction.

  When the leading edge of the label sheet conveyed in the forward direction is detected by the sheet detection sensor SN1 (S13), the conveyance motor 105 stops a predetermined time after the leading edge of the label sheet is detected by the sheet detection sensor SN1 ( S14, S15). At this time, the first print line of the label sheet is positioned at the print position. Here, the time during which the label sheet is conveyed after the leading edge of the label sheet is detected by the sheet detection sensor SN1 (conveyance distance) varies depending on the type of print label and the arrangement of the print characters.

  Next, when the head of the print start position of the label sheet is positioned at the print position, the carriage motor 109 is rotated in the forward direction to move the print carriage 103 from the home position in a direction orthogonal to the label sheet conveyance direction (label sheet width direction). The movement is started (S16), and when a preset set time t2 has elapsed, the carriage motor 109 is stopped (S17, S18), and stopped at the print start position in the label sheet width direction.

  Next, in FIG. 8, when the print carriage 103 stops, the elevating motor 111 is driven in reverse (S19), and the thermal head 101 is lowered. Note that the transmission system for transmitting the drive from the lift motor 111 to the thermal head 101 is, for example, a combination of a link and a cam (not shown) so that the thermal head 101 repeatedly descends and rises by rotating the lift motor in one direction. ).

  In this way, when the thermal head 101 is lowered to a position where the ink ribbon is pressed against the label sheet surface (S20), the transport motor 107 is stopped (S21), and the print carriage 103 is printed by one line in the label sheet width direction. Move to the end position (S22).

  At this time, the ink ribbon is wound up in conjunction with the movement of the print carriage 103 in the print direction, and the heat applied to the thermal head 101 is controlled to start printing (S23). At this time, the carriage 103 moves at a speed of 35.3 mm / second when using a commercial power source with an AC adapter, and at a speed of 17.1 mm / second when using a battery power source. Printing is done.

  Next, the print carriage moves to the print end position for one line and the print operation for one line is ended (S24, S25).

  When the printing operation for one line is completed, the carriage motor 109 is stopped (S26), and the lift motor 111 is driven (S27), thereby driving the lift motor 111 by a predetermined amount to raise the thermal head 101. (S28, S29), the pressure contact state between the print head and the ink ribbon is released.

  Next, in FIG. 9, along with the end of the printing process described above, the carriage motor 101 is driven in reverse to return the print carriage 103 to the home position (S30). When the print carriage 103 reaches the home position (S31), the carriage motor 109 is stopped (S32).

  When the printing of the last line of the label sheet is not completed (S33), the transport motor 107 is driven (S34), the label sheet is transported by one print line (S35), and the printing operation of the line is performed. Is repeated (S15 to S32).

  In this way, when all the printing lines of the label sheet have been completed (S33), the transport motor 107 is driven to rotate forward (S36), and the label sheet is discharged to the label sheet discharge port 5 (FIG. 1) of the printing apparatus. (B)) to discharge outside. The discharge of the label sheet is performed by continuing the drive of the conveyance motor 107 after the set time (t4) has elapsed after the trailing edge of the label sheet has passed the sheet detection sensor SN1 (S37) (S38, S39). In this way, the printing operation for one label sheet is completed.

  FIG. 10 is a timing chart of the motor drive pulse signal and the print strobe signal in the high-speed print mode (when the AC power supply is activated).

  FIG. 11 shows a timing chart of the motor drive pulse signal and the print strobe signal in the low-speed print mode (during battery operation).

  As shown in FIGS. 10 and 11, the printing cycle of the thermal head 101 is defined by a print strobe signal. Since the drive pulse signal of the print carriage 103 is output in synchronization with the print strobe signal, the print strobe signal having a different period is output in the high-speed print mode and the low-speed print mode, so that the desired print mode can be obtained. Can be set. The print strobe signals having different periods are clock signals f2, f3, f4 having various frequencies obtained by dividing the basic oscillation signal f1 output from the crystal oscillation circuits 22 and 23 shown in FIG. Can be created by combining.

  As shown in FIG. 10, the print strobe signal is applied to the thermal head 101 in a low state to melt the ink on the ink ribbon to adhere the ink on the print medium (label sheet). In the high state, the voltage application to the thermal head 101 is canceled and the thermal head 101 is cooled in the meantime.

  Since the amount of heat necessary for the ink on the ink ribbon to melt is constant, the current value (peak) that flows through the thermal head 101 by increasing the application time to the thermal head 101 (T1 in FIG. 10, T2 in FIG. 11). Current) can be reduced. In addition, the lower the ratio of the low state (duty ratio) in one cycle of the print strobe signal, the lower the average power consumption per unit time consumed by the thermal head 101. It can be delayed.

  In this printing apparatus, the cycle of the print strobe signal in the high-speed printing mode shown in FIG. 10 is 2.7 milliseconds, and the energization time to the print head is 1% because the duty ratio is about 50%. .4 milliseconds. On the other hand, the cycle of the print strobe signal in the low-speed print mode shown in FIG. 11 is 5.5 milliseconds, and the energization time to the print head is 1.5 millimeters because the duty ratio is about 27%. Seconds.

  As a result, the duty ratio decreases from 50% in the high-speed printing mode to 27%, so that the average power consumption consumed by the thermal head 101 can be reduced by about 50% compared to the high-speed printing mode. It is.

  This delays the voltage drop of the battery output voltage, lengthens the usage time, increases the number of printed label sheets, and lengthens the high state (non-energized state) of the print strobe signal, thereby dissipating the thermal head. Since the time can be lengthened, the situation in which characters are crushed can be prevented and the printing quality can be improved at the same time.

  By the way, as described above, in the low-speed printing mode, the period of the print strobe signal is increased by about 50% from 2.7 milliseconds in the high-speed printing mode to 5.5 milliseconds. Although the printing time at the time becomes slower, the paper feed speed of the print line and the drive speed of the thermal head 101 in the printing process can be the same as the high speed printing mode even in the low speed printing mode, so the total printing time of one label sheet Is greatly affected by the print pattern such as the number of print lines, but only a delay of about 32% at maximum.

  In the above-described embodiment, the print carriage is moved on the label sheet stationary for each line to execute the print operation for one line, and the speed of the print carriage and the cycle of the strobe signal at that time are set as the power supply type. However, in a device that prints by moving the tape-like label sheet, and handling the tape-like label sheet that is smaller than the thermal head width, the label sheet transport speed and the strobe signal cycle are What is necessary is just to make it switch by classification.

  As described above in detail, in the printing apparatus according to the present invention, in the two-power-supply type printing apparatus of AC power source and battery power source, the printing means for printing characters or figures on the printing medium, the printing medium or the printing medium A moving means for moving any of the printing means in the printing direction; a power detection means for detecting whether the power supply is an AC power supply or a battery power supply and outputting a power type signal; the printing means and the moving means; Control means for controlling, and the control means switches a cycle of a print control signal for driving and controlling a print head constituting the printing means according to the power supply type signal, and moves by the moving means. The speed is controlled to a speed synchronized with the cycle of the print control signal.

  As a result, although the printing speed is somewhat reduced, the operating time of the printing apparatus when the battery power is driven is extended without reducing the printing performance of the printing apparatus.

  The present invention is a dual-power-supply type printing apparatus, which does not deteriorate the print quality even when the battery is operated, and does not complicate the control program or control circuit. A printing apparatus that increases the number of printable sheets by reducing the image quality is provided, and has industrial applicability.
