Description

[0001]
BACKGROUND OF THE INVENTION
The present invention can be read by a computer storing a time switching device that shifts the current time on the switching date in an area where daylight saving time is introduced, and a program that includes a command for causing the computer to execute the operation of such a time switching device. The present invention relates to a recording medium.
[0002]
[Prior art]
Sales data processing devices such as electronic cash registers and POS (Point of Sales) terminals are used in various stores.
[0003]
Such a sales data processing apparatus has a function of printing sales data in the form of a receipt, a journal, a time zone report, or the like. In order to manage the sales data, that is, when and what products are sold, the sales data processing apparatus includes a time measuring means for measuring the current date and time.
[0004]
By the way, as is well known, in many advanced countries except Japan, daylight saving time has been introduced in order to promote energy conservation in summer, which increases living time by about one hour at a time. Therefore, in an area where such daylight saving time is introduced, it is necessary to shift the current date and time counted by the timing means to the switching date and time. Therefore, the change of the current date and time has to be performed manually by the operator after the end of business or before the start of business, which is troublesome.
[0005]
Therefore, a sales data processing device having a function of automatically performing such a time change operation has been developed.
[0006]
[Problems to be solved by the invention]
However, although the conventional sales data processing apparatus can change the time as described above, there is no specification for changing the time during business hours.
[0007]
On the other hand, in recent years, with the diversification of consumers, an increasing number of stores are open 24 hours or late night. In such stores, the daylight saving time switching occurs during the business hours.
[0008]
Therefore, the time of receipt printing time, journal printing time, time zone report calculation destination, etc. at this time becomes ambiguous, and there arises a problem that the time zone total cannot be printed with correct time distribution.
[0009]
An object of the present invention is to make it possible to print the total time zone with a correct time distribution even at the time of switching, thereby recognizing a time shift due to the switching of time and preventing confusion.
[0016]
[Means for Solving the Problems]
Claim 1 The means of the invention is as follows.
The time switching device includes a time measuring means, a first discriminating means, a current time changing means, a second discriminating means, and a printing means.
The time measuring means measures the current date and time.
The first determining means determines whether or not the current date and time counted by the time measuring means has reached a predetermined date and time.
The current time changing means shifts the current time in the time measuring means by a predetermined time when it is determined by the first determining means that the predetermined date has been reached.
The second discriminating unit discriminates whether or not a predetermined time has elapsed since the current time was shifted by a predetermined time by the current time changing unit based on the time measurement result by the clocking unit.
The printing means prints a message indicating that the current time is shifted by a predetermined time on the paper on which the sales data is printed until it is determined by the second determination means that the predetermined time has elapsed.
[0017]
Claims 2 The means of the invention is as follows.
The computer-readable recording medium stores a program including an instruction that causes the computer to execute the following processing when the current time is shifted by a predetermined time at a predetermined date and time.
The first process is a process for determining whether or not the current date and time has reached the predetermined date and time.
The second process is a process of shifting the current time by a predetermined time in the time measuring means for measuring the current date and time when it is determined that the predetermined date and time has been reached.
The third process is a process for determining whether or not a predetermined time has elapsed since the current time was shifted by a predetermined time based on the time measurement result of the time measuring means.
The fourth process is a process of printing a message indicating that the current time is shifted by a predetermined time on the paper on which the sales data is printed until it is determined that the predetermined time has elapsed.
[0018]
Claim 1 And claims 2 The operation of the means of the present invention is as follows.
When the current time arrives at a predetermined date and time that should be shifted by a predetermined time, the current time is shifted by the predetermined time, and then the current time is shifted by a predetermined time for a predetermined time with respect to the sheet on which the sales data is printed. Print a message.
Accordingly, it is possible to warn that the time switching has been performed for a predetermined time after the time switching, thereby recognizing a time shift due to the time switching and preventing confusion.

[0027]
FIG. 1B is a diagram showing the main configuration of the RAM 12. The current time memory 12A, summer time switching setting memory 12B, time zone setting memory 12C, time zone total memory 12D, flag area 12E, switching message character memory. Various memory areas such as 12F, work memory 12G and journal memory 12H are allocated.
[0028]
Here, the current time memory 12 </ b> A stores the current date and time according to the time measured by the clock 26.
[0029]
As shown in FIG. 2A, the summer time switching setting memory 12B includes a winter time switching date memory 12B1 that stores the date for switching from summer time to winter time, and a summer time switching date memory that stores the date for switching from winter time to summer time. 12B2 and a delay time memory 12B3 that stores a delay time (minutes) indicating how much time is shifted at the time of switching.
[0030]
As shown in FIG. 2 (B), the time zone setting memory 12C is a time number memory 12C1 that stores the number of business hours, a calculation start time memory 12C2 that stores a calculation start time that is a business start time, and a report that is printed out. An interval time memory 12C3 that stores an interval time (minute) that is an interval to be performed, and a final Z date memory 12C4 that stores a final Z date that is a date when the settlement process is executed last.
[0031]
As shown in FIG. 2C, the time zone total memory 12D includes one time memory 12D1 for storing one hour (minute) of one time zone memory for storing time zone totals. And a plurality of memories according to time zones. Here, the memory by time zone includes a number memory 12D2A for storing the total number of sales data in the time zone and a money amount memory 12D2B for storing the total amount of sales data in the time zone. Then, the number of the memory by time zone is as follows: the value of the time memory 12C1 is A, the value of the interval time memory 12C3 is B, the value of the delay time memory 12B3 is C, and the value of the time memory 12D1 is one memory. If D,
A x B / (the greatest common divisor of C and D (minutes))
It becomes. For example, if A = 8 hours, B = 60 minutes, C = 60 minutes, and D = 30 minutes, the number of memory by time zone is 8 × 60/30 = 16.
[0032]
As shown in FIG. 2D, the flag area 12E is set at the switching print FLGSN memory 12E1 for storing the switching print FLGSN set at the switching date and time from winter to summer, and at the switching date and time from summer to winter. The switching print FLGNS memory 12E2 for storing the switching print FLGNS and the switching print FLG memory 12E3 for storing the switching print FLG set when printing the switching message.
[0033]
The character memory 12F stores an arbitrary switching message. For example, "--DST START--" is printed as a switching message printed when switching from winter to summer, and printed when switching from summer to winter. "--DST END--" is stored as a switching message.
[0034]
The work memory 12G is used to hold various data when the CPU 10 executes a “time zone report issuing process” described later. As shown in FIG. 2E, the print memory time memory 12G1 , Print EWork time memory 12G2, number / money work memory 12G3, message work memory 12G4, work time memory 12G5, counter x12G6x, counter y12G6y, and the like.
[0035]
The journal memory 12H constitutes various sales totals, and the contents are updated every time sales data is registered. That is, as shown in FIG. 2F, the print data is sequentially stored every time sales data is registered. Further, when the current time is switched, data indicating that the switching has been performed is also stored.
[0036]
Next, the operation of the “time zone report issuance process” in such a configuration will be described with reference to a series of flowcharts shown in FIGS. Here, a program for realizing each function described in these flowcharts is stored in the storage medium 16 in the form of a program code readable by the CPU 10, and the contents thereof are loaded into the RAM 12. . The same applies to other flowcharts in the embodiments described later.
[0037]
That is, when the operator instructs the issuance of the time zone report by a predetermined operation of the input device 20, the CPU 10 first switches the switching printing stored in the switching printing FLGSN memory 12E1, the switching printing FLGNS memory 12E2, and the switching printing FLG memory 12E3. The FLGSN, the switching printing FLGNS, and the switching printing FLG are respectively reset (step S10).
[0038]
Thereafter, it is confirmed whether or not the current time stored in the current time memory 12A has passed the final Z date stored in the final Z date memory 12C4 (step S11). Proceed to
[0039]
On the other hand, if it is determined that the last Z date has passed, the current date stored in the current time memory 12A is the winter time switching date stored in the winter time switching date memory 12B1 or It is determined whether or not the date is later (step S12). If so, the switch print FLGSN stored in the switch print FLGSN memory 12E1 is turned on (= 1) (step S13), and the process proceeds to step S17 described later.
[0040]
On the other hand, if it is determined that the current date has not reached the winter time switching date, then the current date stored in the current time memory 12A is the daylight saving time switching date stored in the daylight saving time switching date memory 12B2. Determines whether or not the date is after that (step S14). If it is determined that the current date has not yet reached the daylight saving time switching date, the process proceeds to step S17 described later. On the other hand, when it is determined that the current date is the daylight saving time switching date or later date, the current date (time) stored in the current time memory 12A is further set to 0:00 or later time. If not, the process proceeds to step S17 to be described later. If it is determined that the current date is 0:00 or later, the switching print FLGNS stored in the switching print FLGNS memory 12E2 is turned on (= 1) (step S16), and the next time Proceed to step S17.
[0041]
Thus, in step S17, the values of the counter x12G6x and the counter y12G6y are both reset to “1”. After that, the calculation start time stored in the calculation start time memory 12C2 is read out and stored in the print work time memory 12G1 (step S18).
[0042]
Next, the calculation end time is calculated (step S19). That is, the interval time stored in the interval time memory 12C3 is added to the calculation start time stored in the printing SWork time memory 12G1, and the calculation result is stored in the printing EWork time memory 12G2.
[0043]
Then, it is determined whether or not the time stored in the print EWork time memory 12G2 is 24:00 or later (step S20). Otherwise, the process proceeds to step S29 described later. On the other hand, if so, it is further determined whether or not the switching printing FLGSN stored in the switching printing FLGSN memory 12E1 is on (step S21).
[0044]
Here, when it is determined that the switching print FLGSN is on, the current time stored in the current time memory 12A is the time obtained by adding the delay time stored in the delay time memory 12B3 to 0:00 or It is determined whether or not it is after (step S22). If not, the process proceeds to step S29 described later. On the other hand, if so, a process for switching to winter time is performed (step S23). That is, the result obtained by subtracting 24:00 from the time stored in the print EWork time memory 12G2 and further subtracting the Delay time stored in the Delay time memory 12B3 is overwritten and stored in the print EWork time memory 12G2. Then, after the print data (in this case, “--DST END--”) stored in the switching message character memory 12F is read out to the message work memory 12G4 in preparation for printing (step S24), step S28 described later is performed. Proceed to
[0045]
If it is determined in step S21 that the switching print FLGSN is not on, it is further determined whether or not the switching print FLGNS stored in the switching print FLGNS memory 12E2 is on (step S25).
[0046]
If it is determined that the switching print FLGNS is not ON, the process proceeds to step S29 described later. On the other hand, when it is determined that the switching print FLGNS is on, a process for switching to daylight saving time is performed (step S26). That is, a result obtained by subtracting 24:00 from the time stored in the print EWork time memory 12G2 and adding the Delay time stored in the Delay time memory 12B3 is overwritten and stored in the print EWork time memory 12G2. Then, after the print data (in this case, “--DST START--”) stored in the switching message character memory 12F is read out to the message work memory 12G4 for preparation for printing (step S27), the next step S28 is performed. Proceed to
[0047]
Thus, in step S28, the switching printing FLG stored in the switching printing FLG memory 12E3 is turned on (= 1).
[0048]
Thereafter, the number of items and the amount of the product are read (step S29). That is, out of a plurality of time zone total memories in the time zone total memory 12D, the data is read from the number memory 12D2A and the amount memory 12D2B of the xth time zone memory indicated by the value of the counter x12G6x, and the number and amount work Store in the memory 12G3. And the first time to output is read (step S30). That is, the calculation start time stored in the print work time memory 12G1 is stored in the work time memory 12G5.
[0049]
Next, it is determined whether or not the time stored in the print EWork time memory 12G2 is 24:00 or later (step S31). If not, the process proceeds to step S33 described later, and so on. If there is, the result obtained by subtracting 24:00 from the time stored in the print EWork time memory 12G2 is overwritten and stored in the print EWork time memory 12G2 (step S32), and the process proceeds to the next step S33.
[0050]
Thus, in step S33, the value of the counter x12G6x is incremented by "+1". Thereafter, the time stored in the time memory 12G5 is added to the time stored in the time memory 12D1 for one memory, and the result is overwritten and stored in the work time memory 12G5 ( Step S34). Then, it is determined whether or not the time stored in the work time memory 12G5 has reached the time obtained by adding the interval time stored in the interval time memory 12C3 to the time stored in the print SW work time memory 12G1 ( Step S35), if so, the number and amount stored in the number of cases / amount work memory 12G3 are the xth number indicated by the value of the counter x12G6x among the plurality of time zone memories in the time zone total memory 12D. The number of cases and the amount of money stored in the number-of-times memory 12D2A and the amount of money memory 12D2B of the time zone are added, and the results are overwritten and stored in the number of cases / amount work memory 12G3 (step S36). Then, the process returns to step S33.
[0051]
Thus, when the time in the work time memory 12G5 reaches the time obtained by adding the interval time to the time in the print SW memory time memory 12G1 in step S35, the printing process is performed (step S37). That is, the printing device 24 prints the time stored in the printing work time memory 12G1, the time stored in the printing Ework time memory 12G21, and the number and amount stored in the number / money work memory 12G3 on the receipt paper.
[0052]
Thereafter, it is determined whether or not the switching printing FLG stored in the switching printing FLG memory 12E3 is on (= 1) (step S38). If not, the process proceeds to step S40 described later. On the other hand, if the switching print FLG is on, the print data stored in the message work memory 12G4 is printed on the receipt paper by the printing device 24 (step S39). Then, the calculation start time is updated (step S40). That is, the interval time stored in the interval time memory 12C3 is added to the calculation start time stored in the print SW time time memory 12G1, and the calculation result is overwritten and stored in the print SW work time memory 12G1.
[0053]
Thereafter, it is determined whether or not the switching printing FLG stored in the switching printing FLG memory 12E3 is ON (= 1) (step S41). Otherwise, the process proceeds to step S46 described later.
[0054]
If the switching printing FLG is on, the switching printing FLG is reset (= 0) (step S42), and then it is determined whether or not the switching printing FLGSN stored in the switching printing FLGSN memory 12E1 is on. (Step S43).
[0055]
Here, when it is determined that the switching print FLGSN is on, the winter time is set (step S44). That is, a result obtained by subtracting 24:00 from the calculation start time stored in the print SW memory time memory 12G1 and further subtracting the delay time stored in the delay time memory 12B3 is overwritten and stored in the print SW work time memory 12G1. To do. Then, the switching printing FLGSN stored in the switching printing FLGSN memory 12E1 is reset (step S45), and the process proceeds to step S48 described later.
[0056]
On the other hand, if it is determined in step S43 that the switching print FLGSN is not on, the daylight saving time is set (step S46). That is, 24:00 is subtracted from the calculation start time stored in the print SW memory time memory 12G1, the delay time stored in the Delay time memory 12B3 is added to the result, and the calculation result is used as the print SW work time memory 12G1. Overwrite and memorize. Then, the switching printing FLGNS stored in the switching printing FLGNS memory 12E2 is reset (step S47), and the process proceeds to the next step S48.
[0057]
Thus, in step S48, the value of the counter y12G6y is incremented by "+1". Thereafter, it is determined whether or not the updated value of the counter y12G6y has exceeded the number of details to be printed on the report (step S49), and if not, the process returns to step S19.
[0058]
In this way, the above processing is repeated, and if the value of the counter y12G6y exceeds the number of details to be printed on the report, the receipt is issued, that is, the receipt paper is cut (step S50). Exit.
[0059]
Note that the current date and time stored in the current time memory 12A is changed as shown in FIG. This operation is performed periodically.
[0060]
That is, first, it is determined whether or not the current date and time stored in the current time memory 12A is the winter time switching date stored in the winter time switching date memory 12B1 (step S60). If not, the process proceeds to step S62, which will be described later. If so, the delay time stored in the delay time memory 12B3 is added to the current date and time stored in the current time memory 12A, and the calculation result is displayed as the current time. After overwriting the time memory 12A (step S61), the process proceeds to the next step S62.
[0061]
Thus, in step S62, it is determined whether or not the current date and time stored in the current time memory 12A is the daylight saving time switching date stored in the daylight saving time switching date memory 12B2. If not, the current time switching process is terminated, and if so, the delay time stored in the delay time memory 12B3 is subtracted from the current date and time stored in the current time memory 12A. The calculation result is overwritten and stored in the current time memory 12A (step S63), and the current time switching process is terminated.
[0062]
Through the above processing, reports as shown in FIGS. 7A to 8B are obtained.
[0063]
That is, (A) and (B) of FIG. 7 show an example in which the interval time is 60 minutes and the delay time is 60 minutes. Here, FIG. 7A is an example when changing from winter time to daylight saving time. In this case, summer switching print 30 indicating the start of daylight saving time at the stage when 24:00 of the last day of winter time has passed. It is carried out. On the other hand, FIG. 7B is an example when changing from summer time to winter time. In this case, the time changes when the time becomes 10:00, and the time changes to 0: After printing the time zone sales data of 00-1: 00, the winter switching printing 32 indicating the end of summer time is performed.
[0064]
8A and 8B show an example in which the interval time is 60 minutes and the delay time is 90 minutes. Here, FIG. 8A is an example when changing from winter time to daylight saving time. In this case, summer switching printing 30 is performed after the last day 24:00 of winter time. . On the other hand, FIG. 8B is an example when changing from summer time to winter time. In this case, the time changes when the time becomes 1:30, and the time changes. Sometimes the interval time has not passed yet, so sales data for the time zone of 01: 00-0: 30 is printed, and then the winter switching print 32 is performed.
[0065]
[Second Embodiment]
Next, a second embodiment of the present invention will be described.
[0066]
The configuration of the electronic cash register as the sales data processing apparatus to which the time switching apparatus according to the second embodiment is applied is the same as that in the first embodiment, and thus the description thereof is omitted.
[0067]
FIG. 9A is a flowchart of “receipt printing process”.
[0068]
That is, when the operator registers sales data by a predetermined operation of the input device 20, the CPU 10 first uses the printing device 24 to store the character “receipt” on the receipt paper and the current date and time stored in the current time memory 12A. The sales data registered in the journal memory 12H is printed (step S60). Thereafter, the current date and time stored in the current time memory 12A is within a predetermined number of days of the winter time switching date and time stored in the winter time switching date memory 12B1 or the daylight saving time switching date and time stored in the summer time switching date memory 12B2. It is determined whether or not the date is reached (step S61). If not, the current date and time stored in the current time memory 12A is the winter time switching date and time stored in the winter time switching date memory 12B1 or the daylight saving time switching date and time stored in the summer time switching date memory 12B2. Is determined (step S62). If not, the “receipt printing process” is terminated.
[0069]
On the other hand, if it is determined in step S61 that the current date / time is within a predetermined number of days of the winter time switching date / time or the daylight saving time switching date / time, the number of days before the switching date / time is calculated (step S63). As shown in FIG. 9B, the calculated number of days is printed by the printing device 24 (step S64), and this “receipt printing process” is terminated.
[0070]
If it is determined in step S62 that the current date / time has passed the winter time switching date / time or the daylight saving time switching date / time, it is determined whether the current date / time is the current day of any of the switching dates (step S65). If so, as shown in FIG. 9B, the summer switching message is printed by the printing device 24 if it is a summer switching day, and the winter switching message is printed by the printing device 24 if it is a winter switching day. Then, the “receipt printing process” is terminated.
[0071]
On the other hand, when it is determined in step S65 that the current date and time is not the current day of any of the switching dates, it is further determined whether or not the current date and time is within a predetermined number of days from any of the switching dates (step S67). . If not, the “receipt printing process” is terminated. If so, as shown in FIG. 9D, the switching start date is printed by the printing device 24 (step S68), and this “receipt printing process” is terminated.
[0072]
As mentioned above, although this invention was demonstrated by embodiment, this invention is not limited to the said embodiment, Of course, a various deformation | transformation change is possible.
[0073]
For example, although the above embodiment has described the printing process for a report or a receipt, the print target may be a journal.
[0074]
In the first embodiment, the print data stored in the switching message character memory 12F is stored in the message work memory 12G4 by determining whether it is the switching date in the “time zone report issuing process”. However, when the current time is shifted by a predetermined time in the current time switching process, the print data is stored in the message work memory 12G4, and if it is stored in the “time zone report issuance process”, it is printed. You may do it.
[0075]
【The invention's effect】
According to the present invention, when the current time arrives at a predetermined date and time when the current time should be shifted by a predetermined time, the current time is shifted by the predetermined time, and a message is printed on the paper on which the sales data is printed. Therefore, the time zone total can be printed with the correct time distribution even when the time is switched, thereby making it possible to recognize the time lag due to the time switching and prevent confusion.
