JP-A-9-58644

  Although not clearly described in the above-mentioned prior art, when creating a printed material having a notation corresponding to the weight measurement result, the user usually places the object to be measured on the weight measuring device, and operates the operation means. A series of handling procedures are required in which the user lowers the object to be measured from the weight measuring device after the printing device creates a printed matter by performing some appropriate operation, and the burden on the user is heavy. In particular, when a printed matter related to each of a plurality of objects to be measured is sequentially created, it is necessary to repeat the above procedure for each object to be measured.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a printing apparatus that can create a printed material on which the weight of the object to be measured is written with a small labor load and improve convenience.

  In order to achieve the above object, the present invention provides a printing apparatus connected to a weight measuring apparatus that measures the weight of an object to be measured and outputs corresponding weight data, and a conveying means that conveys a medium to be printed. A printing unit that performs printing on the printing medium conveyed by the conveyance unit, a cutting unit that cuts the printing medium printed by the printing unit, and a control unit. The means determines whether or not the corresponding weight value has increased or decreased based on the weight data from the weight measuring device; if it is determined in the determination process that the weight value has increased or decreased, the weight increase or decrease A calculation process for calculating a value; a printing process for controlling the conveying means and the printing means and performing printing on the print medium corresponding to the weight increase / decrease value calculated in the calculation process; the weight from the weight measuring device; When the weight value corresponding to the data becomes a predetermined value, the transport medium and the cutting means are controlled to cut the print medium printed by the printing process, and the weight increase / decrease value is displayed. A cutting process for generating a printed matter.

  In the printing apparatus of the present invention, the printing unit performs printing on the printing medium conveyed by the conveying unit, and the cutting unit cuts the printing medium on which the printing has been performed. Created. On the other hand, the printing device is connected to a weight measuring device that measures the weight of the object to be measured and outputs the corresponding weight data, and generates the above-described printed material that represents the print corresponding to the weight value of the object to be measured. be able to.

  That is, it is determined by the control means whether or not the weight value corresponding to the weight data from the weight measuring device has increased or decreased (determination process), and when it is determined that the weight value has increased or decreased, the weight increase or decrease value is calculated. (Calculation process). As a result, for example, when the user places a new measurement object on the weight measuring device and the weight value to be measured increases, the weight increase value is calculated, or the user can measure the weight on the weight measuring device. When the measured weight value decreases by lowering the measurement object, the weight decrease value is calculated. In the printing process, a print corresponding to the weight increase / decrease value (weight increase value or weight decrease value) calculated as described above is formed on the print medium.

  Thereafter, when the weight value of the weight data from the weight measuring device becomes a predetermined value (for example, zero), the control unit cuts the print-receiving medium on which the printing is formed as described above (cutting process). Thus, a printed matter is generated.

  This eliminates the need for an operation terminal for operating the printing device, and does not require a printing instruction operation for the printing device, and the user simply puts the object to be measured on the weighing device and then lowers it. The printed matter on which the weight increase / decrease value (weight increase value or weight decrease value) to be printed can be automatically created. As a result, the user's labor burden can be reduced and the convenience can be improved.

  According to the present invention, it is possible to create a printed material on which the weight of the object to be measured is written with a small labor load, and to improve convenience.

  Embodiments of the present invention will be described below with reference to the drawings.

<System outline>
In FIG. 1, the scale system WS includes a print label producing apparatus 100 as a printing apparatus and a weight measuring apparatus 200 (balance). The print label producing apparatus 100 and the weight measuring apparatus 200 are connected by a USB cable 159 so that information can be transmitted and received (details will be described later).

  The print label producing apparatus 100 includes a main body housing 2. On the front side of the main body housing 2, a discharge port 6 </ b> A is formed through which a label tape 20 </ b> A (see FIG. 2 described later) on which printing is formed is discharged to the outside. A liquid crystal display (LCD) 27 and a key input unit 4 are disposed on the front surface of the main body housing 2 above the discharge port 6A. The liquid crystal display 27 displays various screens and the like under the control of the CPU 44 described later. The key input unit 4 includes a plurality of (six in this example) keys. The main body housing 2 is provided with a host socket 105H.

  The weight measuring apparatus 200 is provided with a mounting table 200A on which an object to be measured (see luggage A, B, C, etc. described later) to be measured, and a target socket 205T.

  The USB cable 159 includes a first connector 159H that causes the connected device to function as a host, a second connector 159T that allows the connected device to function as a target, and a cable body disposed between the first connector 159H and the second connector 159T. 159M. In this example, the USB cable 159 has a first connector 159H attached (connected) to the host socket 105H of the print label producing apparatus 100, and a second connector to the target socket 205T of the weight measuring apparatus 200. 159T is installed. Therefore, in the functional relationship between the print label producing device 100 and the weight measuring device 200, the print label producing device 100 functions as a host device, and the weight measuring device 200 functions as a target device.

<Print label production device>
Next, a detailed configuration of the print label producing apparatus 100 will be described with reference to FIG.

  In FIG. 2, a label tape roll 20 in which a label tape 20 </ b> A (corresponding to an example of a print medium) having a predetermined width is wound in a roll shape is accommodated in the main body housing 2. The label tape 20A includes, for example, a long heat-sensitive sheet having a self-coloring property (so-called thermal paper) and a release paper bonded to one side of the heat-sensitive sheet with an adhesive. The label tape roll 20 is formed in a cartridge, for example, and the main body housing 2 is provided with a cartridge holder (not shown) to which the cartridge can be attached and detached. Instead of the cartridge system as described above, the label tape roll 20 is directly stored in the main body housing 2 and the label tape 20A is rotated while the label tape roll 20 is rotated inside the main body housing 2. You may make it pay out.

  The label tape 20A is fed from the label tape roll 20 and conveyed by a platen roller 26 (corresponding to an example of a conveying means). The platen roller 26 is driven by a platen roller motor 208, whereby the label tape 20A is fed out from the label tape roll 20 and conveyed. The platen roller motor 208 is controlled by a platen roller drive circuit 209.

  The label tape 20A to be conveyed is sandwiched between the thermal head 25 (corresponding to an example of a printing unit) and the platen roller 26 and guided to the discharge port 6A. In addition, when an appropriate identification mark is provided on the label tape 20A, the sensor 22 detects the mark and outputs a corresponding detection signal.

  The thermal head 25 includes a plurality of heating elements in a direction orthogonal to the transport direction of the label tape 20A. The platen roller 26 is disposed on the side of the thermal head 25 facing the surface on which the heat generating elements are provided. The heating element is energized according to the dot pattern data to be printed, whereby a desired text character or the like is printed on the printing area S of the label tape 20A passing between the thermal head 25 and the platen roller 26. . Driving (energization control) of each heat generating element provided in the thermal head 25 is performed by the print driving circuit 205.

  In this example, a cutter unit 21 (corresponding to an example of a cutting means) including a movable blade 21A and a fixed blade 21B is disposed inside the discharge port 6A. The label tape 20A printed by the thermal head 25 has a width orthogonal to the tape transport direction by the reciprocating movement of the movable blade 21A at a predetermined timing by an actuator (not shown) such as a cutting motor or solenoid. It is cut (divided) in the direction, and becomes a print label L of a predetermined length (see FIG. 5 described later) and is discharged from the discharge port 6A. Instead of such an automatic cutting operation by the driving force of the actuator, a manual cutting in which the user manually cuts the movable blade 21A back and forth may be used. Alternatively, the fact that the label tape 20A to be conveyed has reached a predetermined cutting position is displayed on the liquid crystal display 27 or the like, and the user who sees the display operates the predetermined cutting button of the key input unit 4 to operate the above. The movable blade 21A may be moved by an actuator to perform cutting.

  In this example, a half cutter 31 provided on the upstream side of the cutter unit 21 along the transport direction of the label tape 20A is disposed. The half cutter 31 partially moves the label tape 20A printed by the thermal head 25 in the thickness direction by reciprocating at a predetermined timing by an actuator (not shown) such as a half-cutting motor or a solenoid. Cut (half cut). Similar to the cutter unit 21, the half cutter 31 may be a manual half-cut by manually moving the half-cutter 31 by the user instead of the automatic cutting operation by the driving force of the actuator, and an appropriate display was seen. The movable blade 21 </ b> A may be moved by the above-described actuator by a user's operation of a half-cut button to perform half-cut.

  In FIG. 2, a control circuit 40 is disposed on a control board (not shown) in the main body housing 2.

  The control circuit 40 is provided with a CPU 44 (corresponding to an example of control means). The CPU 44 is connected to an input / output interface 41, a ROM 46, a flash memory (EEPROM) 47, and a RAM 48 (an example of storage means) via a data bus 42. The USB communication interface 43H is connected.

  The input / output interface 41 is connected to the print drive circuit 205, the platen roller drive circuit 209, the liquid crystal display 27, and the key input unit 4.

  The USB communication interface 43H performs information communication (for example, serial communication) using the USB cable 159 with the weight measuring device 200, which is a target device, via the host socket 105H.

  The RAM 48 temporarily stores various calculation results calculated by the CPU 44. The RAM 48 is provided with a reception buffer 48A for expanding and holding data received from the weight measuring device 200, a work memory (not shown) for storing various calculation data, and the like.

  The ROM 46 reads out, for example, print data developed in the reception buffer 48A and drives the thermal head 25 and the platen roller motor 208, and a control program related to execution of the flows shown in FIGS. Various programs necessary for control are stored.

  The CPU 44 performs processing according to a program stored in the ROM 46 in advance using the temporary storage function of the RAM 48, and controls the overall operation of the print label producing apparatus 100 (see flowcharts of FIGS. 7 and 13 described later).

<Creation of print label>
In the printed label producing apparatus 100 having the above configuration, as shown in FIG. 2, the thermal head 25 performs printing R on the label tape 20A conveyed by the platen roller 26, and the label tape on which printing R has been performed. When the cutter unit 21 cuts 20A, a print label L (corresponding to an example of a printed matter) is created.

  An example of the printed label L to be created is shown in FIG. This example is an example where the weight of the object to be measured placed on the placing table 200A of the weight measuring apparatus 200 is 1000 grams. In the print label L, the text character “ “Weight 100 g” is formed as the print R.

  Another example of the printed label L to be created is shown in FIG. This example is an example when a plurality of weight notations are performed corresponding to the weight detection results of the plurality of objects to be measured. That is, in correspondence with the case where the weights of the three objects to be measured are 100 grams, 200 grams, and 300 grams, the printing character R of the text character “Weight 100 g” representing each detection result on one printed label L, the text The print R of the characters “Weight 200g” and the print R of the text characters “Weight 300g” are successively formed in this order (details of the forming process will be described later).

<Features of this embodiment>
The feature of this embodiment lies in the flow of processing when the print label creating apparatus 100 creates a print label based on the weight detection result of the weight measuring apparatus 200 as described above. Hereinafter, the details will be described in order.

<Flow of printed label production 1>
FIGS. 5A to 5C show an example in which the print label L shown in FIG. 3 is created. That is, for example, from the state where nothing is placed on the mounting table 200A of the weight measuring device 200 as shown in FIG. 5A, the user places the load A having a weight of 100 g as shown in FIG. Then, the 100 g weight data is input to the print label producing apparatus 100, and the corresponding “Weight 100g” notation is printed on the label tape 20A. Then, as shown in FIG. 5 (c), when the user lowers the load A from the mounting table 200A, the cutter unit 21 cuts the portion of the label tape 20A upstream from the above notation (full). The print label L is generated by being cut and discharged from the discharge port 6A. As a result, the cut portion is positioned at the upstream end portion of the print label L, and the full cut line FC is formed by the cutting (see also FIG. 3 described above).

<Flow of printing label production 2>
FIGS. 6A to 6E show an example in which the print label L shown in FIG. 4 is created. That is, for example, when the user places a load A having a weight of 100 g as shown in FIG. 6B from a state where nothing is placed on the mounting table 200A of the weight measuring device 200 as shown in FIG. Similarly to the above, “Weight 100 g” corresponding to the weight data of 100 g is printed on the label tape 20A. Thereafter, when the user places a baggage B having a weight of 200 g on the baggage A as shown in FIG. 6C, a difference from the measurement result of 100 g is calculated. Thereby, the notation of “Weight 200g” corresponding to the difference 200g is printed on the label tape 20A in such a manner that it continues on the upstream side in the transport direction of the “Weight 100g”. At this time, a half cut line HC (see also FIG. 4 described above) is formed by the above-described half cutter 31 between the “Weight 200 g” described portion and the “Weight 100 g” described portion (see FIG. 4 described above). In FIG. 6, it is indicated by a solid line).

  Thereafter, when the user places a load C having a weight of 300 g on the load B as shown in FIG. 6D, a difference from the previous measurement result is calculated, and the difference corresponds to the difference 300 g. The expression “Weight 300g” is printed in such a manner that it continues on the upstream side in the transport direction of the “Weight 200g”. Also at this time, a half-cut line HC (see FIG. 4 described above) is formed by the half cutter 31 between the “Weight 300 g” notation and the “Weight 200 g” notation (the solid line in FIG. 6). Abbreviated).

  Then, as shown in FIG. 6 (e), when the user lowers all the packages A, B, C from the mounting table 200A, the last "Weight 300g" of the label tape 20A is performed by the cutter unit 21. The portion upstream of the notation portion is cut (full cut) to generate the print label L, which is discharged from the discharge port 6A. As described above, the cut portion is positioned at the upstream end portion of the print label L as a result, and the full cut line FC is formed by the cutting (see also FIG. 4 described above).

<Control procedure>
Next, in order to implement | achieve said method, the process procedure performed by CPU44 of the print label production apparatus 100 is demonstrated in detail based on the flowchart shown in FIG. The procedure executed below is a process executed by the CPU 44 based on the control program stored in the ROM 46 (the same applies to FIG. 13 described later).

  First, in step S10, the CPU 44 initializes weight information to be used later as an index of the execution timing of full cut to “0”.

  Thereafter, in step S20, the CPU 44 obtains the weight data from the weight measuring device 200, and whether or not the weight value represented by the weight data has changed (in other words, whether a new load or the like has been placed on the mounting table 200A). Determine whether. If the weight value does not change, this determination is not satisfied (S20: NO), and a loop standby is performed. If there is a change in the weight value, this determination is satisfied (S20: YES), and the routine goes to Step S30.

  In step S30, the CPU 44 determines whether or not the change in the weight value in step S20 is an increase. If the weight value decreases, the determination is not satisfied (S30: NO), and the process proceeds to step S100 described later. If the weight value has increased, this determination is satisfied (S30: YES), and the process proceeds to step S40. In addition, the process which performs said step S20 and step S30 is equivalent to an example of the determination process as described in each claim.

  In step S40, the CPU 44 determines whether or not the weight data from the weight measuring device 200 after having been determined to increase in step S30 as described above has passed for a fixed time (in other words, predetermined). It is determined whether or not the time variation of the plurality of weight data obtained is within a predetermined range and has been stabilized. The determination is not satisfied until a certain time elapses with almost no change (S40: NO), and the loop waits. If a certain time elapses with almost no change, the determination is satisfied (S40: YES), and the process goes to step S50. Transition. The process of executing step S40 corresponds to an example of a stabilization determination process described in each claim.

  In step S50, the CPU 44 calculates (determines) the determined weight value of the weight data, which has become stable in step S40.

  Thereafter, in step S60, the CPU 44 calculates a weight increase value by subtracting the weight information from the determined weight value calculated in step S50. The process of executing step S60 corresponds to an example of an increase calculation process described in each claim, and also corresponds to an example of a calculation process.

  In step S70, the CPU 44 determines whether or not the weight increase value calculated in step S60 has exceeded a predetermined threshold value. The significance of this threshold is as follows. That is, for example, a slight increase or decrease in weight may occur when a label is affixed to a luggage or a label affixed to a luggage is peeled off while the luggage is placed on the weight measuring device 200. The threshold value in step S70 is for excluding such a minute weight increase / decrease from the target of the printing process described later. If the weight increase value is less than or equal to the above threshold, the determination is not satisfied (S70: NO), and the same procedure is repeated by returning to step S20. If the weight increase value exceeds the threshold value, this determination is satisfied (S70: YES), and the process proceeds to step S80. Note that the process of executing step S70 corresponds to an example of a threshold value determination process described in each claim.

  In step S80, the CPU 44 controls the platen roller 26 and the thermal head 25 as described above to form (print) the print R corresponding to the weight increase value calculated in step S60 on the label tape 20A. The process of executing step S80 corresponds to an example of a printing process described in each claim.

  Thereafter, in step S85, the CPU 44 controls the half cutter 31 and the platen roller 26, and the portion of the label tape 20A on which the printing R is performed in step S80, where the printing R is formed (the printing area as the notation portion). Half-cut processing (formation of the half-cut line HC) is performed at a predetermined site upstream of S).

  In step S90, the CPU 44 updates the weight information by adding the weight increase value calculated in step S60 to the weight information held at this time (for example, in the RAM 48). (The updated weight information is again held in the RAM 48 or the like). Thereafter, the process returns to step S20, and the same procedure is repeated thereafter. Note that the process of executing step S90 corresponds to an example of a first incremental update process described in each claim, and also corresponds to an example of an update process.

  On the other hand, in step S100, where the determination in step S30 is not satisfied, the CPU 44 determines that the weight value represented by the weight data from the weight measuring device 200 is a predetermined value (for example, in the example shown in FIGS. 5 and 6). It is determined whether or not it is zero. If the weight value is a predetermined value, the determination is satisfied (S100: YES), and the process proceeds to step S110 described later. If the weight value is not the predetermined value, the determination is not satisfied (S100: NO), and the process proceeds to step S120.

  In step S120, the CPU 44 calculates a decrease in the weight value when it is determined in step S30 that the weight value has decreased as described above. At this time, the determined weight value is calculated after the weight value is stabilized in the same manner as in Steps S40 and S50 described above, and the determined weight value is obtained from the update information held at this time as in Step S60. The weight reduction may be calculated by subtracting. When step S120 is completed as described above, the process proceeds to step S130. The process of executing step S120 corresponds to an example of a decrease calculation process described in each claim and also corresponds to an example of a calculation process.

  In step S130, the CPU 44 reduces and updates (updates) the weight information by subtracting the weight decrease calculated in step S120 from the weight information held at this time (for example, in the RAM 48). The weight information is again held in the RAM 48 or the like). Thereafter, the process returns to step S20, and the same procedure is repeated thereafter. Note that the process of executing step S130 corresponds to an example of a first reduction update process described in each claim, and also corresponds to an example of an update process.

  On the other hand, in step S110, where the determination in step S100 is satisfied and the process proceeds, the CPU 44 controls the cutter unit 21 and the platen roller 26, and similarly to step S85, the label tape 20A that has performed printing R in step S80. A full cut process (formation of the full cut line FC) is performed at a predetermined portion upstream of the portion where the print R is formed (the print region S as the notation portion), and the print label L is generated. . That is, the label tape 20A is cut (divided) in the width direction. The process of executing step S110 corresponds to an example of a cutting process described in each claim. Thereafter, this flow is terminated.

<Effect of embodiment>
As described above, in the present embodiment, it is determined whether or not the weight value corresponding to the weight data from the weight measuring device 200 has increased (see Step S20 and Step S30 above), and it has been determined that the weight value has increased. In the case, the weight increase value is calculated (see step S60). Accordingly, the weight increase value is calculated when the user newly places a load on the weight measuring apparatus 200. In the printing process of step S80, the print R corresponding to the weight increase value calculated as described above is formed on the label tape 20A. Thereafter, when the weight value of the weight data from the weight measuring device 200 becomes a predetermined value (for example, zero) (see step S100), the label tape 20A on which the print R is formed as described above is cut. By doing this (see step S80 above), the print label L is generated.

  As a result, an operation terminal for operating the print label producing apparatus 100 is not required, and a print instruction operation for the print label producing apparatus 100 is not required, and the user appropriately loads the load on the weight measuring apparatus 200. By simply lowering it later, the print label L on which the corresponding weight increase value is written can be automatically created. As a result, convenience for the user can be improved.

  In the present embodiment, in particular, when it is determined in step S80 that the weight increase value exceeds the threshold value in the threshold determination process in step S70, printing R corresponding to the weight increase value is performed. As a result, for example, when a label is attached to the luggage while the luggage is placed on the weight measuring device 200, or when a slight increase or decrease in weight occurs such as when the attached label is peeled off, printing is performed. It can be excluded from processing.

  In this embodiment, in particular, the increase calculation process in step S60 is performed after the measurement result by the weight measuring device 200 in step S40 becomes stable. Thereby, it is possible to calculate the weight increase value with high accuracy.

  In the present embodiment, in particular, every time a piece of luggage is placed on the weight measuring device 200, the print R corresponding to the weight increase value is performed in the print process in step S80, and the first increase update process in step S90 is performed. When the weight information is updated in the increasing direction and all the loads on the weight measuring device 200 are unloaded and the weight information becomes zero, the label tape 20A is cut by the cutting process of step S110. As a result, one print label L (see FIGS. 4 and 6) having print notations corresponding to the weight value of each package in order can be generated.

  At this time, in particular, as shown in FIG. 8 and FIG. 6 described above, the printing order of the print R on the print label L generated and discharged from the discharge port 6A is from the downstream side in the transport direction (in other words, from the front end side in the discharge direction). The order is “Weight 100 g” → “Weight 200 g” → “Weight 300 g” toward the upstream side (in other words, the rear end side in the discharge direction). That is, as described above, there is a one-to-one correspondence with the order of luggage A → luggage B → luggage C when sequentially placed on the mounting table 200A of the weight measuring device 200. Thereby, it is easy for the user to understand the correspondence between each package and its weight value, which is particularly convenient.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and technical idea of the present invention. Hereinafter, such modifications will be described in order.

(1) Addition of arrow mark indicating stacking order In other words, in this modified example, as shown in FIG. 9, the print label R of “Weight 100 g” connected to each other via the half-cut line HC in the print label L Part, “Weight 200 g” print R notation part, “Weight 300 g” print R notation part, and above each of the weight A on the weight measuring device 200 as described above, the load A → the load B → the load C An arrow mark M indicating that the sheets are sequentially placed in order is also printed.

  According to this modification, by the printing of the arrow M, 100 g of luggage A is first placed on the weight measuring device 200, and then 200 g of luggage B is placed on the luggage A, and then The effect of knowing at a glance that 300 g of the load C is placed on the load B is obtained.

(2) Numbering is given to each notation. That is, in this modification, as shown in FIG. 10, the notation part of the print R of “Weight 100g” connected to each other via the half-cut line HC in the print label L, "Weight 200g" print R notation part, "Weight 300g" print R notation part, "No. 18-001", "No. 18-002", "No. 18-003" Numbering notation N is also printed.

  According to this modified example, when a bill corresponding to each of the above-mentioned notation parts in the printed label L is made by the above-mentioned numbering notation N, for example, “No. -001 "and the bill for 200g package B are given the same" No.18-002 "as above, and the bill for 300g package C is given" No.18-003 "as above. Can be clarified.

(3) When printing is performed when a load is sequentially unloaded from the weight measuring device, the flow of processing when creating a print label with the print label producing device 100 of the present modification corresponds to FIG. 5 and FIG. 6, respectively. This will be described with reference to FIGS.

<Flow of printed label production in this modified example 1>
FIGS. 11A to 11C show an example in which the print label L shown in FIG. 3 is created by the method of this modification. That is, for example, from the state where nothing is placed on the mounting table 200A of the weight measuring device 200 as shown in FIG. 11 (a), the user places the load A having a weight of 100g as shown in FIG. 11 (b).

  When the user unloads the load A from the mounting table 200A from this state, the 100 g weight data is input to the print label producing apparatus 100, and the corresponding "Weight 100g" notation is printed on the label tape 20A. (See the upper part of FIG. 11C). Then, further, the cutter unit 21 cuts (full cut) the upstream portion of the label tape 20A from the above notation to generate the print label L, which is discharged from the discharge port 6A (FIG. 11 (c). ) Refer to the lower part).

<Flow of printed label production in this modification # 2>
12A to 12E show an example in which the print label L shown in FIG. 4 is created by the method of this modification. That is, for example, as shown in FIG. 12 (a), from a state where nothing is placed on the mounting table 200A of the weight measuring device 200, the user can load 100g of luggage A and 200g of weight as shown in FIG. 12 (b). Load the luggage B and the luggage C weighing 300g. Thereby, the measurement result by the weight measuring apparatus 200 becomes 100g + 200g + 300g = 600g.

  After that, when the user drops the load C having the uppermost weight of 300 g as shown in FIG. 12C, the difference between the measurement result at this time (100 g + 200 g = 300 g) and the measurement result of 600 g is the same as above. Calculated. As a result, “Weight 300 g” corresponding to the 300 g weight data corresponding to the difference 300 g is printed on the label tape 20A.

  Thereafter, when the user further lowers the luggage B having a weight of 200 g as shown in FIG. 12 (d), the difference from the measurement result is calculated in the same manner, and the expression “Weight 200 g” corresponding to the difference 200 g is Printing is performed on the label tape 20A in a manner that is continuous to the upstream side of the “Weight 300g” in the transport direction. At this time, as in the above-described embodiment, a half-cut line HC (see also FIG. 4 described above) is formed between the “Weight 300g” notation and the “Weight 200g” notation (see FIG. 4 described above). 12 is indicated by a solid line).

  After that, when the user lowers the last package A having a weight of 100 g as shown in FIG. 12 (e), the difference from the previous measurement result is calculated, and the expression “Weight 100g” corresponding to the difference 100g is calculated. Is printed in such a manner that it continues to the upstream side of the “Weight 200 g” in the transport direction. Also at this time, a half-cut line HC (see FIG. 4 described above) is formed by the half cutter 31 between the “Weight 200g” notation and the “Weight 100g” notation (the solid line in FIG. 12). Abbreviated). Thereafter, the cutter unit 21 cuts (full cut) the upstream portion of the label tape 20 </ b> A from the last “Weight 100 g” notation to generate the print label L, which is discharged from the discharge port 6 </ b> A. The As described above, the cut portion is positioned at the upstream end portion of the print label L as a result, and the full cut line FC is formed by the cutting (see also FIG. 4 described above).

<Control procedure>
Next, a processing procedure executed by the CPU 44 of the print label producing apparatus 100 in order to realize the above technique in the present modification will be described in detail based on the flowchart shown in FIG. The same steps as those in FIG. 7 of the above embodiment are denoted by the same reference numerals, and description thereof will be omitted or simplified as appropriate.

  As shown in FIG. 13, the CPU 44 of the print label producing apparatus 100 according to the present modification proceeds to step S <b> 35 through steps S <b> 10 and S <b> 20 similar to the above embodiment.

  In step S35, the CPU 44 determines whether or not the change in the weight value in step S20 is a decrease. If the weight value increases, the determination is not satisfied (S30: NO), and the process proceeds to step S125 described later. If the weight value is decreasing, this determination is satisfied (S35: YES), and the process proceeds to step S40 similar to the above embodiment. In addition, the process which performs the said step S20 and step S35 is equivalent to an example of the determination process as described in each claim in this modification.

  Thereafter, the process proceeds to step S65 through steps S40 and S50 similar to those in the above embodiment.

  In step S65, the CPU 44 calculates a weight decrease value by subtracting the determined weight value calculated in step S50 from the weight information. The process of executing step S65 corresponds to an example of a decrease calculation process described in each claim, and also corresponds to an example of a calculation process.

  In step S75, the CPU 44 determines whether the weight reduction value calculated in step S65 has exceeded a predetermined threshold value. This threshold value is appropriately set in the same meaning as the threshold value in the above embodiment, and may be the same value as the threshold value in the embodiment or may be a different value. If the weight reduction value is equal to or smaller than the threshold value, the determination is not satisfied (S75: NO), and the process proceeds to step S95 described later. If the weight reduction value exceeds the threshold value, this determination is satisfied (S75: YES), and the process proceeds to step S77. The process of executing step S75 corresponds to an example of the threshold determination process described in each claim in this modification.

  In step S77, the CPU 44 controls the platen roller 26 and the thermal head 25 as described above to form (print) the print R corresponding to the weight reduction value calculated in step S65 on the label tape 20A. The process of executing step S77 corresponds to an example of a printing process described in each claim in this modification.

  Thereafter, in step S79, as in step S100, the CPU 44 determines whether or not the weight value represented by the weight data from the weight measuring device 200 has reached a predetermined value (for example, zero as described above). . If the weight value is a predetermined value, this determination is satisfied (S79: YES), and the process proceeds to step S110 described later. If the weight value is not the predetermined value, this determination is not satisfied (S79: NO), and the process proceeds to step S85 similar to the above embodiment.

  Thereafter, after the same step S85 as in the above embodiment, in step S95, the CPU 44 calculates the weight decrease value calculated in the step S65 from the weight information held at this time (for example, in the RAM 48). By subtracting, the weight information is reduced and updated (the updated weight information is again held in the RAM 48 or the like). Thereafter, the process returns to step S20, and the same procedure is repeated thereafter. Note that the process of executing step S95 corresponds to an example of a second reduction update process described in each claim and also corresponds to an example of an update process.

  In step S125, where the determination in step S35 is not satisfied, the CPU 44 calculates an increase in the weight value when it is determined in step S35 that the weight value has increased as described above. At that time, the determined weight value is calculated after the weight value is stabilized in the same manner as in Steps S40 and S50 described above, and the determined weight value is added to the update information held at this time as in Step S65. The weight increase may be calculated by adding. When step S125 is completed as described above, the process proceeds to step S135. The process of executing step S125 corresponds to an example of a first incremental update process described in each claim, and also corresponds to an example of an update process.

  In step S135, the CPU 44 increases and updates (updates) the weight information by adding the weight increase calculated in step S125 to the weight information held at this time (for example, in the RAM 48). The weight information is again held in the RAM 48 or the like). Thereafter, the process returns to step S20, and the same procedure is repeated thereafter. Note that the process of executing step S135 corresponds to an example of a second incremental update process described in each claim, and also corresponds to an example of an update process.

  On the other hand, in step S110 similar to the above that shifts when the determination in step S100 is satisfied, as described above, the CPU 44 controls the cutter unit 21 and the platen roller 26, and for the label on which printing R has been performed in step S77. A full cut process (formation of the full cut line FC) is performed at a predetermined portion upstream of the portion of the tape 20A where the print R is formed (the print region S as a notation portion), and the print label L is printed. Generate. That is, the label tape 20A is cut (divided) in the width direction. The process of executing step S110 corresponds to an example of the cutting process described in each claim in this modification. Thereafter, this flow is terminated.

  Also by this modification, the same effect as the above-mentioned embodiment is acquired. That is, it is determined whether or not the weight value corresponding to the weight data from the weight measuring device 200 has decreased (see Steps S20 and S35). If it is determined that the weight value has decreased, the weight decrease value is calculated. (See step S65 above). Thereby, the weight reduction value is calculated by the user unloading the load placed on the weight measuring device 200. In the printing process of step S77, the print R corresponding to the weight reduction value calculated as described above is formed on the label tape 20A. Thereafter, when the weight value of the weight data from the weight measuring device 200 becomes a predetermined value (for example, zero) (see step S79), the label tape 20A on which the print R is formed as described above is cut. By doing this (see step S110 above), the print label L is generated.

  As a result, as in the above-described embodiment, an operation terminal for operating the print label producing apparatus 100 is not required, and a print instruction operation for the print label producing apparatus 100 is not required. The print label L on which the corresponding weight reduction value is written can be automatically created simply by placing it on 200 and then lowering it. As a result, convenience for the user can be improved.

  In addition, in this modified example, each time a piece of luggage is unloaded from the weight measuring device 200, the printing R corresponding to the weight reduction value is performed in step S77 and the weight information is updated in the decreasing direction in step S95. After that, when all the packages on the weight measuring device 200 are lowered and the weight information becomes 0, the label tape 20A is cut at the step S110, so that the printing notation corresponding to the weight value of each package is provided in order. In addition, one print label L (see FIGS. 4 and 12) can be generated.

(4) Others In the above description, the case where the half-cut process (formation of the half-cut line HC) is performed by the half cutter in step S85 of FIG. 7 or FIG. 13 is described as an example. For example, when a so-called die-cut label type tape 20A is used, which is composed of an adhesive sheet and release paper, and the adhesive sheet is divided into a label part and a non-label part by cutting, the half cut in step S85 is performed. The processing may be omitted (only the full cut processing of the label tape 20A at the upstream end of the print label L in step S110). In this case, the print label producing apparatus 100 may not include the half cutter 31.

  Further, in the above, the arrows shown in FIG. 2 show an example of the signal flow, and do not limit the signal flow direction.

  The flowcharts shown in FIGS. 7 and 13 are not intended to limit the present invention to the procedures described above, but the procedures may be added / deleted or the order may be changed without departing from the spirit and technical idea of the invention. May be.

  In addition to those already described above, the methods according to the above-described embodiments and modifications may be used in appropriate combination.

  In addition, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
