[0009] Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings. In the following drawings, identical or similar parts are denoted by the same or similar reference numerals. However, it should be noted that the drawings are schematic, and the ratios of dimensions, etc., may differ from those of reality. Therefore, specific dimensions, etc., should be determined by referring to the following description. Furthermore, there may be parts in the drawings where the relationships and ratios of dimensions differ from those of other parts. In this specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals to avoid redundant explanations, and elements not directly related to the present invention are omitted from the illustration.

[0010] (First Embodiment) The weighing device 1 according to the first embodiment of the present invention will be described below with reference to Figures 1 to 5.

[0011] The weighing device 1 according to this embodiment is configured to weigh or count multiple items in multiple batches.

[0012] In this embodiment, the weighing device 1 is described as weighing or counting mail items that are brought in in large quantities in tare bags such as carts, containers, bags, trolleys, or cardboard boxes. However, the present invention is not limited to this case and can also be applied to cases in which the weighing device 1 weighs or counts other items.

[0013] In this embodiment, it is assumed that each of these mail items has approximately the same weight. Examples of such mail items include credit card statements and direct mail.

[0014] As shown in Figure 1, the weighing device 1 according to this embodiment includes a weighing unit 11, a display unit 12, an input unit 13, a storage unit 14, and a control unit 15.

[0015] The weighing unit 11 is configured to weigh the weights of a plurality of postal items (articles). Here, when a plurality of postal items are brought in while being put in a tare bag, the weighing unit 11 starts weighing in that state and is configured to weigh the weights of the plurality of postal items in the state of being put in the tare bag (hereinafter, the weight of the postal item + the weight of the tare bag).

[0016] The display unit 12 is configured to display a screen (for example, the screens shown in FIGS. 2 to 4 described later, etc.) for performing various operations in such a weighing device 1.

[0017] For example, as shown in FIG. 2, the display unit 12 is configured to display the weight of the postal item weighed by the weighing unit 11 in an area 104 described as "weight".

[0018] The input unit 13 is configured to input various information such as input of the weight of the tare bag described later.

[0019] For example, as shown in FIG. 1, the input unit 13 is composed of a numeric keypad (number keys) for inputting numerical values from 0 to 9, a decimal point key for inputting a decimal point (the key described as "." in FIG. 1), and a delete key for deleting the numerical value input by the numeric keypad (the key described as "Delete" in FIG. 1).

[0020] Also, for example, as shown in FIG. 1, the weighing device 1 may include function keys F1 to F4, a zero point key for setting the current weighing state as the zero point (0 g) (the key described as "Zero" in FIG. 1), a tare key used when setting the weight of the tare bag (the key described as "Tare" in FIG. 1), a call key for calling a registered product (the key described as "Call" in FIG. 1), a subtotal key, etc.

[0021] Here, the subtotal key is a key for outputting the total number of postal items counted by the counting unit 11. For example, the subtotal key may be any one of the above-described function keys F1 to F4.

[0022] The memory unit 14 is configured to store various information, such as the weight of the tare bag, as described above. Specifically, the memory unit 14 is configured to store the weight of the tare bag when the tare key (and numeric keypad) is operated in order to perform the actual tare, the number of tare bags, and the master tare, as described later.

[0023] The control unit 15 is configured to calculate the weight of the mail by subtracting the weight of the tare stored in the storage unit 14 from the weighing value (weight of the mail + weight of the tare) from the weighing value (weight of the mail + weight of the tare) from the weighing value (weight of the mail + weight of the tare) from the weighing unit 11.

[0024] In this embodiment, the subtraction of the tare weight from the weighing value of the weighing unit 11 by the control unit 15 is referred to as "tare subtraction." Three types of tare subtraction are envisioned: tare subtraction based on the number of units, master tare subtraction, and actual tare subtraction.

[0025] The tare function subtracts the weight of the tare, entered using the numeric keypad and tare key, from the measured value of the weighing unit 11.

[0026] The master tare function subtracts the weight of the tare obtained from the registered master from the weighing value of the weighing unit 11. Here, the registered master contains weights for various types of tare.

[0027] Actual tare deduction is a method of tare deduction in which an empty tare bag is actually placed on the weighing unit 11 (for example, a scale), and the weight of the tare bag measured by the weighing unit 11 is subtracted from the measured value of the weighing unit 11.

[0028] Furthermore, if the weighing device 1 is a weighing device with counting specifications, the control unit 15 is configured to count the total number of mail items by dividing the calculated weight of the mail items by the weight of each individual mail item.

[0029] Here, the memory unit 14 is configured to store the result (actual) of the above-mentioned weighing or counting operation as history information 102 each time such operation is performed.

[0030] The display unit 12 is configured to display the screen shown in Figure 3 and the history information 102 described above when the area 101 labeled "Weighing History" shown in Figure 2 is pressed.

[0031] For example, as shown in Figure 3, the display unit 12 is configured to display the history information 102 related to the addition operation and the history information 102 related to the subtraction operation, etc.

[0032] Here, the addition operation is the operation of adding the weight (measured value) of the mail items measured by the weighing unit 11 described above, and the history information 102 related to the addition operation is the history information 102 that is labeled "0001", "0002", and "0004" in Figure 3.

[0033] Furthermore, the subtraction operation is a tare operation performed by the control unit 15 described above, and includes, for example, an operation to subtract the weight of the tare placed on the weighing unit 11 from the measured value (actual tare), an operation to input a number corresponding to the weight of the tare and subtract it from the measured value (number tare), and an operation to subtract the weight of the tare obtained from the registration master from the measured value (master tare). The history information 102 related to the subtraction operation is the history information 102 labeled "0003" in Figure 3.

[0034] Here, among the history information 102, the history information 102 relating to operations other than the subtraction operation described above (for example, the addition operation) will be referred to as specific history information 103.

[0035] The control unit 15 is configured to disable the deletion of the specific history information 103 if it is selected as a target for deletion from the history information 102.

[0036] In other words, the control unit 15 is configured to delete history information 102 other than the specific history information 103 (i.e., history information related to subtraction operations) if it is selected as a target for deletion, but not to delete the specific history information 103 if it is selected as a target for deletion.

[0037] This configuration makes it possible to avoid situations where specific history information 103 related to the addition of the weighing value of mail is accidentally deleted.

[0038] Furthermore, with this configuration, for example, if the wrong tare is placed on the scale when performing actual tare tare, if the wrong tare weight is entered when performing placement tare tare, or if the wrong tare weight is obtained when performing master tare tare, the history information 102 related to such subtraction operations can be deleted. As a result, in such cases, the operator can set the correct tare again and perform the subtraction operation (tare tare).

[0039] In this case, the display unit 12 may also be configured to display deleted history information 102 from the history information 102 described above.

[0040] For example, as shown in Figure 3, the display unit 12 may indicate that the deleted history information 102 has been deleted by changing the display method (in the example in Figure 3, by adding diagonal lines).

[0041] Here, the display unit 12 may change the display for the deleted history information 102 from "Subtraction" as shown in Figure 3 to "Deletion".

[0042] Furthermore, the display unit 12 may be configured to display the results after the above-mentioned addition and subtraction operations have been performed in the area 105 labeled "Subtracted Weight" as shown in Figure 4.

[0043] Here, the deleted history information 102 is not reflected in the results after the addition and subtraction operations described above have been performed.

[0044] With this configuration, by retaining the deleted history information 102, it becomes easier to confirm what operations the operator performed, and it also becomes easier to confirm whether there are any errors in the operations performed.

[0045] An example of the operation of the weighing device 1 according to this embodiment will be described below with reference to Figure 5.

[0046] As shown in Figure 5, in step S101, the worker performs the addition and subtraction operations described above.

[0047] In step S102, the storage unit 14 stores the history information 102 related to the above-described operation. The display unit 12 then displays this history information 102 on the screen shown in Figure 3.

[0048] In step S103, the operator selects the history information 102 to be deleted on the screen shown in Figure 3 and presses the area 106 labeled "Delete".

[0049] In step S104, the control unit 15 determines whether the history information 102 selected for deletion is the specific history information 103.

[0050] If the answer is Yes, the process proceeds to step S106; if the answer is No, the process proceeds to step S105.

[0051] In step S105, the control unit 15 deletes the history information 102 that was selected as the target for deletion.

[0052] In step S106, the control unit 15 disables the deletion of the history information 102 (specific history information 103) selected as the target for deletion (i.e., does not delete it).

[0053] According to this embodiment, it is possible to avoid situations where the recorded weight of mail is mistakenly deleted, and to avoid the trouble of having to re-weigh the mail.

[0054] Although the present invention has been described in detail using the embodiments described above, it will be clear to those skilled in the art that the present invention is not limited to the embodiments described herein. The present invention can be implemented in modified and altered forms without departing from the spirit and scope of the invention as defined by the claims. Therefore, the description herein is for illustrative purposes only and is not intended to be restrictive in any way to the present invention. [Explanation of symbols]
