[0002]

2. Description of the Related Art Handy scanners that scan barcodes attached to goods in a sales department, packages in a distribution department, and the like are widely used.

For example, in the case of a merchandise sales registration data processing device, a cashier touches a handy scanner to scan a bar code attached to the merchandise purchased by the customer. Then, the handy scanner converts the scan signal into code data and transmits it to a higher-level device (for example, an electronic cash register). Therefore, the electronic cash register can search for product data corresponding to the code data and register sales of the customer purchased product.

[0004]

By the way, the conventional handy scanner is formed so as to transmit the code data to a host device every time a scanning operation is performed. Therefore, for example, in the case of the commodity sales registration data processing apparatus, when there are a plurality of commodities with the same barcode, the scanning operation is repeated repeatedly for the number of commodities, or the upper apparatus One must move to the electronic cash register and manually enter the number using, for example, a keyboard.

[0005] Thus, the scanning operation requires a lot of trouble, and for example, the ability of the sales registration business for discounted goods and special sale goods is reduced. There is a similar problem in the distribution sector and the like.

It is an object of the present invention to provide a handy scanner which can repeat the same code data as many times as necessary by one scanning operation.

And the total number of transmissions (Nr) can be checked on the display 21.
It is formed so that it can be visually confirmed .

[0011]

The handy scanner 30 is shown in FIG.
The electronic cash register (upper device) 10 shown in FIG.

In FIG. 1, an electronic cash register 1
Reference numeral 0 denotes a control unit that connects the CPU 11, the ROM 12, and the RAM 13 via a bus, a clock circuit 14, a keyboard 20 (keyboard circuit 16), a display 21 (display control circuit 17),
It includes a printer 22 (printer drive circuit 24) and a drawer 23 (drawer opening device 25) connected via the input / output port 18, and is formed to be able to process merchandise sales registration data when switched to the registration mode. That is, code data (product data) is input by scanning a barcode attached to a product or operating a key using the handy scanner 30 to the keyboard 20 connected via the interface (I / F) 15. Do it.

As shown in FIG. 2, the handy scanner 30 includes a CPU 32, a ROM 33, a RAM 34, an optical unit / A / D converter 38 connected via an interface (I / F) 37, and a cable 39. An interface (I / F) 36 and the like for data transmission with the host device (10) are housed in the main body 31. The external shape is as shown in FIG.

That is, when the scanning operation is performed by touching the tip detection section with the bar code attached to the product, the CPU 3
2 receives a scan signal by an interrupt (INT1) process (ST30 in FIG. 5), and scan buffer 3 shown in FIG.
4SC (ST31). The scan signal is converted into code data, temporarily stored in a work area of the RAM 34, and then transmitted to the host device (10) (FIG. 4).
ST14).

Then, the transmission result O is sent from the higher-level device (10).
When K is received (YES in ST15), the CPU 32 sets the timer 35 for repeat transmission control described later (ST16), and the number of transmissions (Nr) for display control.
Is set to "1" (ST18). At this time, the buzzer control means (32, 33) operates, and the buzzer 45 generates a short sound for confirming normal transmission (ST17).

When the code stored in the scan buffer 34SC is abnormal due to the scan operation (S in FIG. 5).
(T32: NO) sets the number of transmissions (Nr) to "0" (ST35). This is for displaying “0” on the display 42 (ST27) because the code data cannot be transmitted even once. The number of transmissions (Nr) is determined by the RAM shown in FIG.
The count value Nr stored in the repeat counter 34R formed from the partial storage area 34. Therefore, this count value includes both the number of transmissions and the number of repeat transmissions.

The code data storage and holding means (34CD), which is one of the technical features of the present invention, stores and holds the code data originally transmitted to the host device (10) by the scanning operation. The code-data buffer 34CD shown in FIG.
Is formed from. This code data buffer 34C
The CPU 32 stores in D (ST33 in FIG. 5). In the case of this embodiment, this code data is stored and, at the same time, that effect (bit “1”) is set in the code data bit buffer 34B of FIG. 2 (S
T34). This is for the convenience of judging between the original transmission when the scanning operation is performed and the repeat transmission described later in detail (ST12 in FIG. 4).

By the way, as shown in FIG. 3, a repeat key 40 operable to be pressed and a readable display 42 are attached to the surface of the main body 31 from outside, specifically, while holding the main body 31. ing. The repeat key 40 is shown in FIG.
Are connected via a switch control circuit 41 shown in FIG.
3 are connected. The buzzer 45 is also connected via a buzzer control circuit 46.

The repeat key 40 is used when the code data stored and held in the code data storage and holding means (34CD) is to be repeatedly transmitted to the electronic cash register (upper device) 10.

That is, the repeat key 40 is set within the set time.
Is pressed, the interrupt (INT2) processing shown in FIG. 6 is skipped because the timer value is not zero (0). Then
In the main process (FIG. 4), the CPU 32 fetches this (ST10) and determines whether or not the code data presence bit is "1". Original transmission by previous scan (ST14)
Is set to "0" when (ST13) is performed,
NO is determined in ST12. If the transmission is normally normal (YES in ST15), the number of transmissions (Nr) is set to "1" (ST18).
O is determined.

When the above conditions are satisfied, the repeat transmission control means operates. This repeat transmission control means includes a CPU 3
2, ROM 33, interface 36,
This is executed in ST20 of FIG. That is, the CPU 32
Transmits the code data stored in the code data storage and holding means (34CD) to the higher-level device (10) repeatedly. In other words, if the repeat key 40 is pressed once after transmission, the same code data is transmitted once only. Therefore, the timer 35, that is, the set time is set again to permit the next repeat key 40 to be pressed (ST22). And
The count value (the number of transmissions) Nr is counted up (Nr =
Nr + 1) (ST24).

Also in the case of this repeat transmission, the buzzer control means (32, 33) operates to generate a short buzzer sound (ST2).
3) The display control means (32, 33) displays the latest count value Nr of the repeat counter 34R (ST27).

The set time is defined as the time when the code data is originally transmitted to the electronic cash register 10 by the scanning operation (YES in ST14 and ST15 in FIG. 4) and in the preceding repeat transmission (YE in ST20 and ST21 in FIG. 4).
This is understood as a period from when S) is performed, during which the next repeat key 40 can be pressed. Specifically, it is set by setting the timer 35 (ST16 OR ST22). Therefore, the code data can be repeatedly transmitted as many times as the number of the same product.

Next, the display control means controls the display of the current count value Nr of the repeat counter 34R on the display 42, and is formed by the CPU 32 and the ROM 33.
Is executed in ST27. The count value Nr displayed on the display 42 is the number of times the code data was originally transmitted by the scan operation (FIG. 5) (ST14) and the repeat transmission by pressing the repeat key 40 (FIG. 6) (ST20).
The total number of transmissions (Nr). Therefore,
When the scan operation is not performed even after the set time has elapsed, or when the transmission and the repeat transmission are malfunctioning (NO in ST15,
In (NO in ST21), the count value Nr of the repeat counter 34R is set to "0" (ST26), so "0" is displayed on the display 42 (ST27).

The buzzer control means includes a CPU 32, R
OM33 and a short buzzer sound (ST17, ST17)
23) and an intermittent buzzer sound for a fixed time (ST25) is generated (ST25). This buzzer control means (32, 33)
Indicates that the transmission of the code data to the host device 10 is normal.
Generates short buzzer sound in other cases, intermittent in other cases
Generates sound, that is, when it is normal and when it is not
Different buzzer sounds can be generated
It is formed as follows. In other words, easier handling
Is being planned.

When the set time set in the timer 35 has elapsed (timed out) (YES in ST11 of FIG. 4), the count value Nr of the repeat counter 34R is set.
Is set to "0" (ST28). Therefore, the display 42
Is displayed as zero ("0") (ST27).

Next, the operation of this embodiment will be described. When the power of the handy scanner 30 is turned on, an initialization process is performed by the main process (FIG. 4). The initialization process is performed in the bit buffer 34 having code data.
B, clearing the repeat counter 34R, the timer 35, the scan buffer 34SC, and the code data buffer (code data storage and holding means) 34CD. When this process ends, the scan operation (IN
T1) and pressing operation of the repeat key 40 shown in FIG. 6 (IN
It becomes a standby state of T2).

First, when a scan operation (FIG. 5) is performed, C
The PU 32 takes in the scan signal and stores it in the scan buffer 34SC (ST30, 31 in FIG. 5). The converted code data is normal (YES in ST32).
Then, the CPU 32 stores the code data in the code data buffer (code data storage / holding unit) 34CD (S
T33). Further, the code data bit "1" is set in the code data bit buffer 34B (ST3).
4). When the above is completed, the scan buffer 34SC is cleared.

Thus, the CPU 32 fetches the scan data based on the main processing (FIG. 4) (ST10),
Proceed to T12 and below. That is, in taking in the scan data, NO is determined in ST11 and the code data existence bit is “1” (YES in ST12), so that the code data existence bit is first set to “0” in ST13, The code data is read from the code data storage and holding means (34CD) and transmitted to the electronic cash register 10 (ST13, ST14). Thereby, the original transmission of the code data by the scanning operation is completed (YE in ST15).
S).

When the original transmission of the code data by the scanning operation is completed, the set time for permitting the pressing operation of the repeat key 40, that is, the timer 35 is set (ST1).
6). Thereafter, the buzzer control means (32, 33) operates to drive the buzzer 45 to generate a short sound as a transmission normal confirmation sound (ST17). Subsequently, the CPU 32 sets the count value Nr of the repeat counter 34R to “1” (ST
18). Therefore, the display control means (32, 33) displays "1" on the display 42 (ST27). That is, it can be visually confirmed that the code data has been transmitted to the host device (10) only once.

However, in case of transmission failure (NO in ST15)
Generates an intermittent sound (ST25). Since the count value Nr is set to "0" (ST26), the display 42
Displays "0". It can be seen that transmission was not originally performed.

Here, if there are five identical products in addition to the scanned product (one), the repeat key 40
Is pressed only once (FIG. 6), within a set time ( ST
(NO at 40), only that key data is stored. The CPU 32 fetches this (ST10), ST1
1, ST12 and ST19 are determined. In this case, ST
11, ST12 and ST19 are all NO. Thus, the repeat transmission control means (32, 33, 36) operates to repeat-transmit the code data stored in the code data storage and holding means (34CD) to the host device (10) (ST20, ST21: YES).

In the case of this repeat transmission, the transmission (S
As in the case of T14 to T18), the timer 35 is reset (ST) to permit the second pressing operation of the repeat key 40.
22), and a short sound is generated (ST23). The count value Nr becomes "2" which is an added value of "1" by the repeat transmission and "1" by the previous original transmission (ST14) (ST24). Therefore, "2" is displayed on the display 42.
Is displayed (ST27).

Thereafter, this procedure is repeated, and the code data is repeated for the remaining four times (YES in ST20 and ST21). The display value at the time when the repeat transmission of all five times is completed is “6” in total of “1” by the scan operation and the number of times (“5”) of pressing the repeat key 40. Therefore, it can be seen that the same code data could be quickly and accurately transmitted and input to the host device (10) six times by one scanning operation for six identical products.

Thereafter, after the set time elapses, the timer 35
Becomes "0", ST11 of the main processing (FIG. 4)
Then, the CPU 32 sets the count value Nr of the repeat counter 34R to "0" (ST in FIG. 4).
28). Therefore, zero ("0") is displayed on the display 42 (ST27).

In FIG. 4, when the data transmission by the scan operation is malfunctioning (NO in ST15), when the repeat transmission by the operation of pressing the repeat key is malfunctioning (ST2).
No. 1) is alerted by an intermittent sound for a fixed time (ST25). In such a case, it is sufficient to restart the scanning operation.

According to this embodiment, the handy scanner 30 is provided with the repeat key 40 which can be pressed from the outside of the main body 31, and the code data storage and holding means (34CD), the timer 35 and the repeat key are provided in the main body 31. Transmission control means (32, 33, 36) and repeat counter 3
4R, display control means (32, 33) and buzzer control means
(32, 33), and the code data by one scanning operation is provided a plurality of times as necessary by the host device (10).
Repeat transmission and whether transmission is normal
Can be confirmed by a buzzer sound and the total number of transmissions (Nr)
Since the total number of products can be visually checked on the display 21, the code data of the same product can be input quickly and accurately by a simple operation.

Since the repeat key 40 and the indicator 42 are attached to the surface of the main body 31 as shown in FIG. 3, the handling is extremely simple. Short sound by buzzer 45,
The generation of intermittent sounds further promotes this.

The count value Nr of the repeat counter 43R is the sum (N + 1) of one original transmission by the scan operation and N repeat transmissions by the repeat key 40.
Is displayed, the display 42 displays the total number of times of successful transmission so far. That is, since the total number of transmissions of the same code data can be easily known, accurate input can be performed.

If the time set by the timer 35 is set to an appropriate value, the operation of pressing the repeat key 40 becomes easy, and the operation can be performed so as not to hinder the scanning operation for the next product.

After the set time has elapsed, the repeat key 4
Since it is formed that the pressing operation of 0 is invalidated,
Erroneous transmission can be prevented.
