DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a merchandise sales data processing apparatus in which a plurality of terminal machines having a merchandise registration function and a higher-level machine for collectively managing these are connected so as to be able to perform data communication when each terminal is powered on. About.

[0002]

2. Description of the Related Art In FIG. 9, a merchandise sales data processing apparatus includes a plurality of terminal machines (for example, electronic cash registers) 10A to 10N having a merchandise registration function and a higher-level machine (for example, a file processor) for collectively managing them.
30, each of which has a terminal machine 1
0 and a data communication line (for example, LA
N) 1 to enable data communication. In addition, the host machine 30 has a data communication line (for example, ISD
N) 2 in many cases to be connected to the highest-level device (not shown) so that data communication is possible.

In such a merchandise sales data processing apparatus, each terminal machine 10 registers merchandise in a sales file 13F,
In addition to accounting for registered products, service point management, credit processing, etc. are performed. In addition, the host machine 30
Various data can be downloaded to each terminal machine 10, and sales data can be collected and collected into a master sales file 23F.
Data collection such as storing in

[0004] The operation of the host machine 30 is not necessarily synchronized with the operation time of each terminal machine 10. For example, with respect to data collection from the terminal machines 10, after all the terminal machines 10 have completed the product sales business (for example, PM1
0:00), and before the store opens (for example, AM)
8:00).

[0005]

By the way, the end of the work of the terminal machine 10 varies, but it is general that the power is turned off after the end of the work. In addition, in the power-off state, the data communication with the host device 30 cannot be performed, and it is constructed and operated as such.

Therefore, for example, when transferring data from the higher-level device 30 to some or all terminal devices 10 or collecting data from each terminal device 10 at 0:00 AM, the person in charge of the higher-level device 30 turns off the power. The power of each of the terminal devices 10 in the state must be individually turned on. This work is extremely time-consuming and time-consuming, and also involves risks. However, the method of collectively turning on and off the power of all the terminal devices 10 on the host device 30 side requires a special control system to be provided, and when all of the terminal devices 10 are to be used, all the terminal devices 10 must be provided. Turning on the terminal machine 10 is wasteful in terms of energy.

An object of the present invention is to provide a merchandise sales data processing apparatus capable of reliably turning on the power of an arbitrary terminal at an arbitrary time.

[0008]

According to a first aspect of the present invention, a plurality of terminal devices having a product registration function and a higher-level device that collectively manages the terminal devices are connected so that data communication can be performed when each terminal is powered on. In the merchandise sales data processing device, the host machine is formed so that the power-on reservation time for each terminal machine can be set and stored, and the power-on reservation time obtained for each terminal machine from the host machine can be set and stored. When the power-on reservation time set and stored is reached, the power of the own device is formed so as to be able to be turned on, and all or a part of the power of each of the terminal devices is surely turned off at an arbitrary time set and stored on the host device side. It is formed so that it can be turned on.

In this invention, the reservation time desired to turn on the power of each terminal machine is set and stored in the host machine. For example, when the power of the terminal is turned off, each terminal obtains the power-on reservation time of the terminal from the host device and stores the setting. Then, when the power-on reservation time set and stored after the power-off of the own device comes, the power of the own device is turned on. Therefore, by simply setting and storing the power-on reservation time for all or some terminal machines in accordance with the schedule of the host machine, the power of any terminal machine can be reliably turned on at the desired time on the host machine. Can be turned on for data communication.

[0010] Further, according to a second aspect of the present invention, there is provided a merchandise sales data processing system in which a plurality of terminal machines having a merchandise registration function and a higher-level machine for collectively managing these are connected so as to be able to perform data communication when each terminal is powered on. In the device,
A power-on reservation time table for setting and storing a power-on reservation time corresponding to each of the terminal devices, and a response control means capable of responding to the inquiry from each terminal device. Inquiry control means for inquiring each terminal unit about its own power-on reservation time to the higher-level device; a power-on execution reservation table capable of storing the responded power-on reservation time; A power-on execution control means for turning on the power of the own device when the power-on execution time stored in the execution reservation table is reached. The terminal device is formed so that its own power supply can be turned on.

In this invention, the inquiry control means of each terminal device inquires of the host device about its own power-on reservation time.
The response control means on the host device responds to the terminal device the power-on reservation time of the terminal device which is set and stored in the power-on reservation time table in advance. The terminal device that has received the response stores the power-on reservation time in the power-on execution reservation table in the terminal device. Thus, the reserved power-on execution control means turns on its own power when the time becomes the same as the power-on execution reservation time stored in the power-on execution reservation table.

Therefore, only by setting and storing the power-on reservation time for all or a part of the terminal machines in accordance with the schedule of the higher-order machine side, the higher-order machine side can set any terminal machine at any desired time. Data communication can be performed while the power supply is reliably turned on, and handling is easy.

According to a third aspect of the present invention, each terminal unit can set and store a fixed-interval power-on reservation time, and each of the reserved power-on execution control means sets and stores a fixed-interval power-on reservation time. In this case, the product sales data processing device is formed so that its own power supply can be turned on.

According to this invention, in addition to the power-on execution reservation time responded from the host device, each terminal unit can set and store the regular-interval power-on reservation time. Further, the reserved power-on execution control means can turn on the power of the own device when the set regular interval power-on reserved time is stored. Therefore, the same operation and effect as those of the invention of claim 2 can be obtained, and furthermore, the power-on reservation time for the self-machine which is set and stored or changed in the host machine after the self-machine power is turned off can be obtained. In addition, there is no restriction on the storage time of the setting of the power-on reservation time on the host machine side, and the applicability is wide.

Further, the invention according to claim 4 is characterized in that the reserved power-on execution control means is configured to turn on a power supply in a shorter one of the power-on reserved time and the regular interval power-on reserved time. Product sales data processing device.

In this invention, the reserved power-on execution control means turns on the power at the earlier one of the power-on reserved time and the fixed-interval power-on reserved time. Therefore, the same operation and effect as those of the third aspect of the invention can be obtained, and the power of the own device can be more reliably and accurately turned on while giving priority to the power-on reservation time set and stored by the upper device.

Further, according to the invention of claim 5, the power-on execution reservation signal can be transmitted to the host machine on condition that each of the terminal devices stores the power-on reservation time in the power-on execution reservation table. The power-on reservation time for each terminal machine formed and stored in the power-on reservation time table on condition that the host machine receives a power-on execution reservation signal from each terminal machine can be erased. It is a formed product sales data processing device.

In this invention, each terminal device transmits a power-on execution reservation signal to the host device on condition that the power-on reservation time is stored in the power-on execution reservation table. The host machine receiving this deletes the power-on reservation time from the power-on reservation time table. Therefore, the same operation and effect as those of the inventions of claims 2 to 4 can be obtained. In addition, the host machine can surely confirm the reservation acceptance of each terminal machine side, and the next set and stored next. Since the identification of the power-on reservation time becomes clear, the reliability and the usability can be further improved.

[0019]

Embodiments of the present invention will be described below with reference to the drawings. This product sales data processing device (10,
30) has a basic configuration similar to that of the conventional example (FIG. 9), and further includes a power-on reservation time table 33T and response control means (31, 32) in the host machine 30 as shown in FIG. Inquiry control means (11, 12) and power-on execution reservation table 1 for each terminal machine 10A to 10N
3T and a reserved power-on execution control means (11, 12) are provided so that the power-on reservation time Tr1 for each terminal device 10 can be set and stored in the host device 30, and each terminal device 10 is transferred from the host device 30 to the host device 30. The acquired power-on reservation time Tr1 can be set and stored, and when the set and stored power-on reservation time has come, the power supply (25) of the own device is formed to be able to be turned on, and the higher-level device 30 can set any desired time. The power supply (25) of all or a part of each of the terminal devices 10A to 10N is automatically and surely turned on, so that data communication can be reliably performed.

In FIG. 1, a host machine 30 includes a CPU 3

And data communication.

In the RAM 23, in addition to the master sales file 33F, a power-on reservation time table 3 shown in FIG.
3T is formed. The HDD and the like are not shown.

The reserved power-on time table 33T includes a reserved power-on time Tr1 corresponding to each terminal device 10.
Is set using the keyboard 34 (YES in ST10 of FIG. 5). Setting memory (ST1
1) is a power-on reservation time setting storage control means (CPU 3
1, ROM 32). As shown in FIG. 2, a plurality of power-on reservation times Tr1 can be set and stored for each terminal device 10.

Inquiry receiving means (CPU 31, ROM 32)
Receives the inquiry about the power supply reservation time from the terminal device 10 (YES in ST12). Then, the setting storage detection control means (CPU 31, ROM 32) searches the power-on reservation time table 33T (ST13), and detects the presence or absence of the power-on reservation time Tr1 for the terminal device 10 (ST14).

Here, the response control means is formed of the ROM 32 storing the response control program and the CPU 31. When it is detected that there is the power-on time in response to an inquiry from each terminal device 10, the power supply is controlled. The ON reservation time Tr1 is responded (present response) (ST15). In addition,
If it is detected that there is no response (ST1)

The power-on reservation time erasure control means includes:
When the signal receiving means (CPU 31, ROM 32) receives a power-on execution reservation signal from the terminal device 10 (ST
17 (YES), that is, on the condition that the reservation is received, the power-on reservation time Tr1 of the terminal 10 stored in the power-on reservation time table 33T is erased (ST18). Can be. Therefore, speaking of the terminal machine 10A in FIG.
First power-on reservation time Tr1 (1/23, 23:40)
Is erased, the next second power-on reservation time (1/2
4, 1:30) becomes clear and is not confused with the first power-on reservation time.

Next, each terminal machine 10 (10A)
As shown in FIG. 1, a CPU 11, a ROM 12, a RAM 1
3, a keyboard 14, a scanner 15, a display 16, a printer 17, an auto-open drawer 18, an interface (I / F) 19 for LAN1, a clock circuit (power-on timer) 20, and an interface (IS) for ISDN2.
/ F) 49 and has a product registration function and an accounting processing function.

The sales data is registered in a sales file 13F in the RAM 13. When the power supply unit (power supply) 25 is turned on, a product registration function and the like can be executed, and data communication with the host machine 30 is possible. Here, the power-on execution reservation table 13 shown in FIGS.
T, a power-on execution table 13Ta shown in FIG. 4B and a regular-interval on execution table 13Tr shown in FIG.

The power-on execution reservation table 13T contains the power-on reservation time Tr1 obtained (responded) from the host machine 30.
Is stored in the fixed interval on execution table 13T.
r stores the regular interval power-on reservation time Tr2. The details will be described later. Power-on execution table 13T
“a” substantially forms the power-on execution reservation table 13T, and is formally separated from the power-on execution reservation table 13T because a fixed-interval power-on function is provided in this embodiment.

The power supply unit 25 is a commercial power supply (AC10).
0V) as an input, for example, a drive power supply of DC12V or DC
A 5 V control power supply and the like can be generated and output, and the battery 26 can be charged. This battery 26
Has a capacity capable of switching the power supply unit 25 to the on state at least in the power off state, and can also drive the clock circuit 20 and the like.

The power ON-OF on the keyboard 14
When the power is turned off using the F switch (not shown),
Prior to this, normal processing (ST20 in FIG. 6) such as storage and storage of sales data is performed. This is the same as in the conventional example.

Here, the inquiry control means provided in each terminal device 10 performs a normal process (ST
20), the host machine 30 is notified of the power-on reservation time T of the machine itself.
A means for inquiring r1 is formed from the ROM 12 and the PU 11 in which the inquiry control program is stored.
1 is executed.

The power-on reservation time setting storage control means includes:
The response receiving means (CPU 11, ROM 12) formed of the OM 12 and the CPU 11 receives the response (ST22).
YES) and there is a response (YES in ST23)
In this case, the power-on reservation time Tr1 is stored in the power-on execution reservation table 13T as shown in FIG.
T24).

Signal transmission control means (CPU 11, ROM 1
2) is a condition that the power-on reservation time Tr1 is stored in the power-on execution reservation table 13T, that is, after the reservation is accepted, the power-on execution reservation signal to that effect is transmitted to the host machine 30. This is executed in ST25 of FIG.

Storage detection control means (CPU 11, ROM 1
2) search the power-on execution reservation table 13T (FIG. 7)
Then, it is detected whether or not the power-on reservation time Tr1 is stored (ST27). If it is detected that there is a memory (YES in ST27), the first time determination means (C
The PU 11 and the ROM 12) compare the current time (time) Ti with the power-on reservation time Tr1 to determine whether or not Ti> Tr1 (ST28).

When Ti> Tr1 (YE in ST28)
S) is meaningless because the current time Ti has passed the power-on reservation time Tr1, and the over-power-on reservation time erasure control means (CPU 11, ROM 12) erases the power-on reservation time Tr1 (ST29). .

When Ti ≦ Tr1 (N in ST28)
O) or when the power-on reservation time Tr1 is not stored (NO in ST27), the validity determination means (CPU1
1, ROM 12) is a fixed interval on execution table (specifically, "fixed interval on execution function column") 13Tr shown in FIG.
(ST30), and it is determined whether it is enabled (flag "1") or disabled (flag "0") (ST31).

When it is determined to be disabled (ST31)
NO), the first set means (CPU 11, ROM 1
2) replaces the power-on execution time Ta1 stored in the power-on execution reservation table 13T with the power-on execution time Ta1.
As shown in FIG. 3B, the power-on execution table 1
It is set to 3Ta (ST39). In this case, ST2
7 is a case of NO and ST28 is a case of NO. Then, after the first set clearing means (CPU 11, ROM 1
2) clears the power-on reservation time Tr1 from the power-on execution reservation table 13T (ST40).

Thus, the timer setting means (CPU 1
1, ROM 12) is a clock circuit (power-on timer) 20
The power-on execution time Ta1 is set (ST41). Thereafter, the power supply (25) is turned off (ST42).

The reserved power-on execution control means includes a ROM 12 storing a reserved power-on execution control program and a CPU.
The power supply (25) is turned on when the current time (time) Ti managed by the clock circuit 20 becomes the power-on execution time Ta1 set in the power timer (20). That is, even in the power-off state, the terminal device 10 itself turns on its own power supply (25) at a desired time (Tr1 = Ta1) on the host device 30, so that data communication with the host device 30 becomes possible. .

By the way, the validity judging means (11, 12)
When it is determined that the function is enabled (YES in ST31), the time creation means (CPU 11, ROM 12) sets the function start time Ts preset and stored in the "function start time column" of the fixed interval on execution table 13Tr shown in FIG. The regular interval power-on reservation time T is used as the regular interval power-on reservation time Tr2.
It is created and stored in r2 (ST32 in FIG. 8).

Second time discriminating means (CPU 11, ROM 1
2) comparing the regular interval power-on reservation time Tr2 with the current time Ti to determine whether or not Ti> Tr2 (S2).
T33). If Ti> Tr2 (YE in ST33)
In S), the regular interval power-on reservation time Tr2 does not make sense, so the process proceeds to ST39 in FIG. That is, the power-on execution time Ta1 set on the higher-level device 30 becomes valid (ST39 and thereafter).

When Ti ≦ Tr2 (N in ST33 of FIG. 8)
O) includes time updating means (CPU 11, ROM 12)
Is a fixed-interval power-on reservation time Tr2 (for example, 1 /
23, 22:00) and an interval Tint (for example, 2 hours) preset in the “interval field”, and updates the regular interval power-on reservation time Tr2 (1/24, 0:00) ( ST34).

Time determination means (CPU 11, ROM 12)
Determines the updated regular power-on reservation time Tr2 as the regular power-on execution time Ta2 (ST35), and stores it in the “regular power-on execution time” column shown in FIG. 4 (ST3).
5) Do it.

Third time determining means (CPU 11, ROM
12) is a fixed regular interval power-on execution time Ta2
Is compared with the power-on reservation time Tr1 obtained from the host machine 30 and stored in the power-on execution reservation table 13T (ST24 in FIG. 6), and it is determined whether or not Ta1 <Ta2 (ST36). . That is, the earlier time is prioritized.

When Ta2 ≦ Ta1 (YE in ST36)
S), the second setting means (CPU 11, ROM 12)
Sets the regular interval power-on execution time Ta2 in the power-on execution table 13Ta shown in FIG. 3B (ST37). Then, the second set after-clearing means (11, 12) clears the regular interval power-on execution time Ta2 from the regular interval on execution table 13Tr shown in FIG. 4 (ST38).

Thus, the power-on execution table 13Ta shown in FIG. 3B stores either the power-on execution time Ta1 or the fixed-interval power-on execution time Ta2, whichever is earlier (ST39 in FIG. 7 or FIG. 8 ST37).

Next, the operation and operation of this embodiment will be described. In the host machine 30, for example, January 23 (1/2
3) At 23:40, a terminal machine (for example, 10A, 1
0B, 10C), for example, when it is considered to collect sales data, timely (for example, 16:00), FIG.
Each terminal device 10A, using a keyboard 34 shown in FIG.
Power-on reservation time for each 10B and 10C (1/23, 2
3:40) Setting input of Tr1 (YE of ST10 in FIG. 5)
S). Then, the power-on reservation time setting storage control means (31, 32) stores it in the power-on reservation time table 33T shown in FIG. 2 (ST11). Terminal machine 1
A different power-on reservation time Tr1 may be set and stored for each 0.

In the host machine 30, it is only necessary to carry out this setting storage operation.

When a power-off request is made at the terminal 10A, for example, at 18:00, the operation of which has been completed, the power-off normal processing (ST2 in FIG. 6) is performed in the same manner as in the conventional example.
0) is performed. However, the power is immediately turned off (ST in FIG. 7).
42) No.

That is, the inquiry control means (11, 12) inquires the host device 30 about the power-on reservation time Tr1 for the own device (10A) (ST21 in FIG. 6). It should be noted that the present invention is not limited to the case where the power is turned off, and may be formed, for example, so that an inquiry can be made periodically.

On the host device 30, the inquiry receiving means (31,
32) receives the inquiry (YES in ST12 of FIG. 5).
Then, the setting storage detection control means (31, 32) searches the power-on reservation time table 33T shown in FIG. 2 (ST1).
3) The power-on reservation time Tr1 (1/23, 23:40) for the terminal device 10A is detected (Y in ST14).
ES). The response control means (31, 32) responds this time Tr1 to the terminal device 10A (ST15).

On the side of the terminal 10A receiving this response by the response receiving means (11, 12) (YES in ST22 and YES in ST23 in FIG. 6), the power-on reservation time setting control means (11, 12) sets The power-on reservation time Tr1 is stored in the power-on execution reservation table 13T shown in FIG. 3A (ST24). Thereafter, the signal transmission control means (11, 12) transmits a power-on execution reservation signal to the effect that the reservation is accepted to the host machine 30 (ST25).

In the host machine 30, the signal receiving means (31, 3)
2) receives the signal (YES in ST17 of FIG. 5), the power-on reservation time erasure control means (31, 32)
The power-on reservation time Tr (1/23, 23: 4) stored in the power-on reservation time table 33T shown in FIG.
0) is erased (ST18). Therefore, the duplicate response can be avoided, so that the next power-on reservation time (1/24,
1:30, 1/24, 2:00) can be easily identified, so that the reliability and the usability can be further improved.

Returning to the terminal device 10A, the storage detection control means (11, 12) searches the power-on execution reservation table 13T shown in FIG. 3A (ST26 in FIG. 7), and finds the power-on reservation time Tr1 (1). / 23, 23:40) is stored (YES in ST27). Then, the first time discriminating means (11, 12) controls the present time (time) managed by the clock circuit 20 [1/23, 18:00].
It is determined that Tr1 ≧ Ti (YES in ST28).

Subsequently, the validity determining means (11, 12)
However, the fixed interval on execution table 13Tr shown in FIG. 4 is searched (ST30), and it is determined whether the fixed interval on execution function is enabled (enabled) (ST31).

If it is not valid (NO in ST31),
The first setting means (11, 12) sets the power-on execution time Ta1 (1/23, 2) same as the power-on reservation time Tr1.
3:40) is set in the power-on execution table 13Ta as shown in FIG. 3B (ST39). Even if the current time Ti is valid (YES in ST31), the current time Ti is set to the regular interval power-on reservation time Tr2 (for example, 1/23, 17: 0).
0) (Y in ST32 and ST33 in FIG. 8).
In ES), the power-on execution time Ta1 set and stored in the host machine 30 has priority and is valid.

Thus, the first setting means (11, 12)
The power-on reservation time Tr1 shown in FIG.
The determined power-on execution time Ta1 is set in the power-on execution table 13Ta shown in (B) (ST3 in FIG. 7).
8) After the first set clearing means (11, 12)
Clears the power-on reservation time Tr1 from the power-on execution reservation table 13T shown in FIG. 3A (ST40).

Here, the timer setting means (11,
12) sets the power-on execution time Ta1 (1/23, 23:40) determined by the power-on timer (20) (ST41). Then, the terminal machine 10A
The power supply (25) is turned off (ST42).

Thereafter, the reserved power-on execution control means (11, 12) is driven by the battery 26, and the current time Ti read from the clock circuit 20 is changed to the power-on execution time set in the power-on timer (20). Ta1 (1 /
23, 23:40), the power supply unit 25
To turn on its own power supply (25).

Therefore, the terminal device 10A and the host device 30 are in a data communicable state.
0 can collect sales data from the terminal machine 10A.

Referring to FIG. 8, that is, the regular interval power-on reservation time T created by the time creation means (11, 12).
r2 (= Ts) [1/23, 22:00 shown in FIG. 4]
Is later than the current time Ti (1/23, 18:00) by the second time determination means (11, 12) (Tr2> T
i) (NO in ST33), the time updating means (11, 12) sets the function start time Ts (1/23,
22:00), an interval Tint that is set in advance to a temporary fixed interval power-on reservation time Tr2 (= Ts).
(2:00) is updated to the actual first regular interval power-on reservation time Tr2 (1/24, 0:00) (ST)
34).

Here, the time determination means (11, 1)
2) determines the regular interval power-on reservation time Tr2 as the regular interval power-on time Ta2 (1/24, 0:00) (S)
T35). The third time discriminating means (11, 12) supplies the power-on reservation time Tr1 (1/2) obtained from the host machine 30 side.
3, 23:40) and this time Ta2 (ST36).
I do.

If Ta1 <Ta2 (YE in ST36)
In S), the power-on reservation time Ta1 set on the earlier higher-level device 30 side, that is, the power-on reservation time Tr1 (1/2)
3, 23:40) becomes effective (ST39 and thereafter in FIG. 7). If Ta1> Ta2 (YES in ST36)
Then, the second setting means (11, 12) sets the regular interval power-on execution time Ta2 in the power-on execution table 13Ta shown in FIG. 3B (ST37). As a result, the second set-after-clearing means (11, 12) clears the regular interval power-on reservation time Tr2 from the regular interval on execution table 13Tr shown in FIG. 4 (ST38).

Therefore, based on the fixed-interval power-on execution time Ta2, the reserved power-on execution control means (11, 1)
When 2) automatically turns on the power supply (25) of its own device (10A), the host device 30 sends the next power-on reservation time Tr1
(For example, “1/24, 1:30” shown in FIG. 2) can be obtained.

Thus, according to this embodiment, the host device 30 is provided with the power-on reservation time table 33T and the response control means (31, 32), and each terminal device 1
0A to 10N are provided with an inquiry control means (11, 12), a power-on execution reservation table 13T, and a reserved power-on execution control means (11, 12), and the host machine 30 has a power-on reservation time for each terminal machine 10. Tr1 is formed so as to be settable and memorizable, and when the power-on reservation time Tr1 obtained from each of the terminal devices 10 from the host machine 30 can be set and stored and the stored power-on reservation time reaches the stored power-on reservation time, the power of the own device ( 25) can be turned on, so that all or a part of the power supply (25) of each of the terminal devices 10A to 10N at an arbitrary time desired (set and stored) on the host device 30 side.
