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 device having abnormal sounding means.

[0002]

2. Description of the Related Art In a product sales data processing device having a control unit (CPU, ROM, RAM, interface, etc.), keyboard, printer, scanner, display, etc., the key in the keyboard is not depressed in a predetermined procedure. When an abnormality such as a key operation error or a paper out of a receipt / journal occurs, an abnormal sounding means such as a buzzer is sounded and a correction is required.

That is, as shown in FIG. 3, an error sound is emitted when an abnormality occurs (ST30), and a key operation error is corrected or the error is canceled by replenishing paper (ST).
31), the error sound is canceled (ST32).

The volume is adjusted according to the installation environment of the product sales data processing device. Generally, the volume is set to be noticeable by the cashier even when the store is busy and the noise is the loudest.

[0005]

However, if the abnormal sounding means is activated during a quiet period in the store, the cashier will be informed of his or her own operation mistakes, which is not only a mental burden but also a customer's anxiety. Suspicious of reliability. Moreover, this is all the more true when the sound is formed until the paper replacement work is started or the replacement is completed, that is, the abnormality is resolved. Further, in a quiet restaurant or the like, even if the volume is set to the minimum level, the sound may be very audible and the customer may feel uncomfortable.

It is an object of the present invention to provide a product sales data processing device having an abnormal sounding function capable of gradually changing the sound volume over time and adjusting the sound volume at each stage.

[0007]

SUMMARY OF THE INVENTION The present invention relates to a product sales data processing apparatus provided with an abnormal sounding means which sounds when an abnormality occurs such as a key operation error on a keyboard or a paper out of a printer. It is characterized in that a volume adjusting means is provided to switch to a plurality of stages so as to gradually increase the volume so that sound can be produced, and to adjust the volume at each stage.

[0008]

According to the present invention having the above-described structure, when there is a key operation error or a paper run-out, the abnormal sounding means is activated to generate a sound and alert the cashier. If the cashier does not notice, the volume will gradually increase over time, and the sound will be switched in multiple stages. Therefore, while the volume is low, the cashier can deal with it without being noticed by others including the customer. The volume at each stage can be adjusted and set by the volume adjusting means.
Therefore, the volume can be adjusted to an appropriate level according to the installation environment and the skill level of the cashier. Therefore, proper operation according to the situation can be performed without impairing the original function of calling attention when an abnormality occurs.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. This product sales data processing device is, as shown in FIG.
Abnormal sounding means (11,
Volume control means (20S, 1) for adjusting the volume at each stage by switching between a plurality of stages so that the volume gradually increases with time and producing sound.
1, 12, 13) are provided.

The general basic configuration means CPU 11, ROM
12, RAM 13, clock circuit 14, input / output port 15,
A control unit 10 including 18, a keyboard 20 (keyboard circuit 16) connected to the control unit 10, a display 21
(Display control circuit 17), printer 22 (printer drive circuit 24), drawer 23 (drawer opening device 25), bar code scanner 30 (scanner control circuit 31), and the like.

The basic functions of this basic configuration,
Since handling and the like is well known, further explanation is omitted.

Here, the abnormal sound generating means is composed of the ROM 12 storing the program shown in FIG. 2, the CPU 11 executing this program, and the electronic sound generating circuit for specifically sounding (sounding) when an abnormality (error) occurs. Buzzer 19
(Input / output port 15).

That is, when an error occurs such as an operation error of various keys of the keyboard or a paper out of the printer 22,
Sound is made at a preset volume (i = 1 in FIG. 2) (ST
12). Then, the volume (i) is switched by the soft timer 1 so as to gradually increase in a plurality of steps over time (ST11, 15, 17). That is, every time the soft timer 1 times out (YES in ST15), the volume (i = 1) is switched to (i = i + 1) (ST).
17). The volume (i) is stored in the RAM 13 and is incremented by "1" every time the time-out is reached. Buzzer 19
Is formed so as to sound with a volume corresponding to the volume (i). However, since it is necessary to regulate the maximum volume (imax), ST16 is introduced.

The setting time of the soft timer 1 can be changed by a numerical keypad of the keyboard 20 or the like. The same applies to the soft timer 2 described later.

When the key operation error is corrected or the paper is replenished to eliminate the error, the buzzer 19 is stopped (YES in ST13, 25).

Further, in this embodiment, since the paper replenishment work requires a relatively long time, while the cashier knows the occurrence of the abnormality by the sound of the buzzer 19 and is trying to eliminate it, the volume is unduly loud. Figure 2
The sound generation stop / redrive function shown in ST14 and ST20 to ST23 is provided.

That is, when the clear key 20C on the keyboard 20 shown in FIG. 1 is depressed, the soft timer 2 is activated and the error sound is released (Y in ST14).
ES, ST20, 21). Therefore, the cashier can settle down and supply paper. However, if you neglect it, the soft timer 2 counts up (ST2
2), the volume (i) is set to the minimum volume (i =
Return to 1) and play the error sound again (ST12)
Formed with things.

Next, the volume adjusting means sets the initial value (i = 1) of the volume (i) stored in the RAM 13 to, for example, (i =
By changing as in 3), the volume at each stage (i)
Is gradually increased to (i = 3), (i = 4), ... That is, by inputting with the setting key 20S on the keyboard 20, the CPU 11 causes the ROM
R based on the program (ST17) stored in 12
The value stored in the AM 13 is rewritten.

In this embodiment having such a configuration, when an abnormality occurs, the abnormal sounding means (11, 12, 15, 19) operates to start the soft timer 1 and sound an error sound (ST11, 12). The initial volume (i) is "1" (ST10). The error is not cleared (N in ST13
O) and the clear key 21C is not depressed (ST
14), the soft timer 1 counts up (YES in ST15), the volume (i) gradually increases over a plurality of stages (ST17). However, the maximum volume (imax) is limited (ST16).

Then, when the sound is produced at a certain stage, the clear key 21C is pushed down (YES in ST14).
Then, the soft timer 2 is started (ST20) and the error sound is canceled (ST21). It is only necessary to cancel the error (corresponding to YES in ST13) in the meantime, but if the error state continues even after the soft timer 2 counts up due to paper replenishment or the like, the volume (i) is set to the initial volume ( After returning to i = 1), an error sound is sounded again (ST11, 12).

According to this embodiment, however, the volume switching type abnormality generating means (11, 12, 15, 19) and the volume adjusting means (20S, 11, 12, 13) are provided, and the time elapses from the time when the abnormality occurs. The volume is gradually increased over multiple stages and the absolute value of the volume can be adjusted at each stage, reducing the mental burden of the cashier and eliminating the distrust of customers. is there. That is, proper operation according to the situation can be performed without impairing the alerting function when an abnormality (error) occurs.

Further, the abnormality generating means is the soft timer 1
Since the volume is switched with, and the setting time can be changed by key operation, more appropriate operation can be performed. The same applies to the soft timer 2 described later.

Further, since the volume adjusting means is formed so as to change the value of the volume (i) by operating the key 20C, it is not necessary to adjust the volume (i) for each switching step one by one. It is easy to handle. In addition, it can be optimally operated even in high-class restaurants.

Further, a sound generation stop / re-drive function (ST1
4, 20 to 23) are provided to stop the sound generation by the intention of the cashier, and as long as the abnormal condition continues, it is configured to return to the minimum volume and re-sound, so that the cashier does not feel discomfort and caution to the cashier again. You can call.
