Abstract

PROBLEM TO BE SOLVED: To obtain an optically reading terminal device efficiently executing correcting operation in warehousing and shipping management by speedily and precisely key-inputting even with a single hand. SOLUTION: When an operator corrects the quantity of merchandise master data, a difference between with the actual number of merchandise is inputted (S130). As the difference of the numerical values at warehousing and shipping management, etc., is not large and not more than one to three normally, the operation can cope with almost cases only by searching a necessary key from among '1', '2' and '3'. As the keys of '1', '2' and '3' are gathered positioned as the key group of the intermediate part of a main body case and the number of key winds are also small, the moving range of the tips of fingers is sufficiently narrowed. Thereby keys can be pressed speedily and precisely even by the tips of the fingers of a hand of extremely low freedom because of supporting a bar code reader handy terminal and the correcting operation is made efficient because the numerical portion is corrected by single hand (S140, S150).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical reading terminal device, and more particularly to an optical reading terminal device for optically reading a display pattern.
The present invention relates to an optical reading terminal device capable of specifying a management target associated with a display pattern and correcting numerical information set for the management target.

[0002]

2. Description of the Related Art Conventionally, when a computer manages the status of goods receipt / shipment and inventory in a warehouse or a mass retailer, light is emitted onto a display pattern such as a bar code attached to each product, and the light is emitted. There is known an optical reading terminal device that optically reads a display pattern from reflected light to transmit information on entry / exit of the product to a host computer side by optical communication or the like (Japanese Patent Application Laid-Open No. HEI 5-120664, JP-A-5-75855, JP-A-7-16243, and the like.

[0003] Such an optical reading terminal device is preliminarily provided.
The management data for each product is received from the host computer and stored in a database internally, and when checking the status of loading and unloading of the product, the operator affixes the product to the optical reading terminal device. Based on the product code read from the barcode, the number of incoming and outgoing goods registered for the relevant product from the database is displayed on the display unit of the optical reading terminal device.

[0004] The operator compares the numerical value managed by the host computer with the actual number of products read from the bar code, and if the numerical values do not match, the operator checks the optical number. An operation of correcting the numerical value by inputting an accurate numerical value with a key existing on the main body case of the reading type terminal device has been performed.

When the optical reading terminal device is returned to a predetermined table, the corrected numerical value is transmitted to the host computer by optical communication or the like, and the management information on the host computer is corrected. .

[0006]

Problems to be Solved by the Invention
Of Japanese Patent Application Publication No. 7-162
In the optical reading terminal device described in Japanese Patent Publication No. 43, an input key group is arranged on the side opposite to the bar code reading port, so that the bar code is read and the correction value is input with the key. When performing this, it is necessary to return to the other hand to press the key hidden in the palm at the time of reading, which is not preferable in terms of the efficiency of the correction work.

For this reason, in the optical reading terminal device described in a part of Japanese Utility Model Application Laid-Open No. 5-75855 and Japanese Patent Application Laid-Open No. HEI 5-120664, a main body case is provided to facilitate input of correction values. Of these, by providing key input means on the same side as the bar code reading port, the key input means can be operated with the other hand without switching the optical reading terminal device.

However, even if it is not necessary to change the hand, the other hand is still used for key input, and after all, the auxiliary work for counting the number of products performed with the other hand is interrupted. Must be used for key input,
The reduction in work efficiency has not been resolved.

In the former optical reading terminal device, some of the fingers supporting the optical reading terminal device are supported by one of the fingers supporting the optical reading terminal device without being changed. It is conceivable to operate a key with a finger, for example, an index finger or a middle finger. However, in order to input a correct numerical value, at least eleven keys, that is, ten keys and an enter key indicating the end of the input are necessary, and the eleven keys need not be operated with the index finger or the middle finger. Not be.

[0010] As described above, searching for and pressing a target key from a large number of keys widely distributed with the index finger or the middle finger is difficult because some of the fingers support the optical reading terminal device. It is difficult to press the key quickly and without fail under the condition that the degree of freedom of the operator is extremely limited, and it may not be possible when the operator's hand is small. Therefore,
Even such a method could not improve the efficiency of the correction work.

An object of the optical reading terminal device of the present invention is to enable quick and accurate key input even with only one hand, and to enable efficient correction work in storage management.

[0012]

Means for Solving the Problems and Effects of the Invention Here, one or more inventions are described, each having the structure and effect described below. The optical reading terminal device of the present invention optically reads a display pattern, specifies a management target associated with the display pattern, and corrects numerical information set for the management target. An information reading device, comprising: an information storage unit that stores numerical information related to the management target; an optical reading unit that optically reads a display pattern; and a display pattern read by the optical reading unit. Display means for specifying the management object to be represented and displaying numerical information stored in the information storage means with respect to the management object; input operation detection means for detecting an input operation from an operator; Correction means for adding and subtracting and correcting the numerical information on the management target stored in the information storage means based on an input operation input by the detection means. And it features.

Here, the display unit specifies the management target represented by the display pattern read by the optical reading unit, and displays numerical information stored in the information storage unit with respect to the management target. The operator confirms the numerical value of this display and compares it with the actual numerical value. If the actual numerical value is different from the actual numerical value, the operator stores the numerical value from the input operation detecting means in the information storage means. An input operation for correcting a numerical value can be performed.

The input is corrected by adding and subtracting numerical information on the management target by the correction means, so that the operator need not input all the numerical values, but only the difference. For example, the numerical value stored in the information storage means is “140” and the actual numerical value is “1” less than “13”.
If it is "9", it is conventionally "1", "3",
The three numbers of "9" are searched and input from the numeric keypad where a large number of keys are widely distributed, and the enter key is finally input. However, according to the present invention, only the key for decreasing "1" Alternatively, it is only necessary to input the key "1" and the enter key.

Normally, the difference (difference) in numerical values in the entry / exit management is not large, and is about 1 to 3 at most. Therefore, the operator can use the keys "1", "2" and "3". In most cases, you can find the key you need. For this reason, as compared with the conventional case where all the keys are input from the beginning, the key of the present invention is compared with the case where the key is searched and pressed from a large number of keys such as eleven keys including the keys “0” to “9” and the enter key which are widely distributed. In the optical reading terminal device, the moving range of the finger is sufficiently reduced.

[0016] Therefore, since the optical reading terminal device is supported by some of the fingers, the other fingers of the same hand having extremely low degree of freedom of movement can be set to "1", "2", and "3". With a maximum of six small keys, a key, an increase key, a decrease key, and an enter key, the range of movement of the fingertip is limited, so that the key can be pressed quickly and accurately enough. For this reason, the correction work becomes efficient.

It is to be noted that the numerical information relating to the management target is received, for example, from the host by the receiving means and stored in the information storage means. The numerical information on the management target stored in the information storage unit corrected by the correction unit is:
For example, the transmission unit transmits the data to the host. Note that the management target includes an article such as a product, and the display pattern includes, for example, a barcode attached to the article.

Further, the input operation detecting means includes a plurality of key input means, and a numerical value added to or subtracted from numerical information by an input operation differs for each key input means.
The keys "1", "2", and "3" described above may be used. In addition to the keys indicating the types of numerical values, the input operation detecting means includes two types of key input means. When an input operation is performed on one of the key input means, the numerical information is incremented by one, and the other key input means is provided. , The numerical information may be decremented by one. In other words, a numeric up key and a down key may be provided, and the number of operations may be increased or decreased. This operation can also be selected from three small keys of the maximum key, the increase key, the decrease key, and the enter key. Therefore, the fingertip can be moved within an extremely narrow range, and the target key can be quickly and accurately pressed. it can. Also, usually, the difference is not large, and is at most about 1 to 3 as described above, and since the difference has a high probability of 1 or 2, the operation can be performed only once or twice,
Even if the key increases or decreases by 1, the efficiency does not decrease.

The input operation detecting means includes a plurality of numerical key input means corresponding to numerical values having different sizes, and an addition / subtraction setting key input means for setting addition / subtraction.
The correction means, when an input operation is performed on any of the numeric key input means and the addition / subtraction setting key input means, for example, when addition is set by the addition / subtraction setting key input means, the numerical information Alternatively, a numerical value corresponding to the numerical key input means may be added. If the subtraction is set by the addition / subtraction setting key input means, the numerical information may be subtracted by the numerical value corresponding to the numerical key input means. For example, as described above, "1",
This is a case where keys “2” and “3”, an increase key, a decrease key, and an enter key are used.

Numeric key input means include "1",
Although the examples of the keys “2” and “3” have been described, only the keys “1” and “2” may be used. If the difference is "3", it is sufficient to input twice with "1" and "2". The number of keys is further reduced, the distribution range is narrowed, and the key can be pressed more quickly and accurately.

In the case where a numeric keypad for input operation is provided on the main body case of the optical reading terminal device, the key input means may double as a part of the numeric keypad. That is, the numeric keys "1", "2",
If the key "3" is arranged at a position where it can be easily pressed with a fingertip together with the increase key, the decrease key and the enter key, the ten keys can be used.

The main body case of the optical reading terminal device has, for example, a head portion and a grip portion having a width smaller than the head portion, and the head portion is located on the abdominal surface of the main body case for reading. The mouth may be provided, display means may be provided on the back side of the head, and input operation detection means may be provided on the back side of the gripping part.

Alternatively, the main body case may have a configuration in which an intermediate portion wider than the grip portion is provided between the head and the grip portion, and key input means is provided in the intermediate portion. With this configuration, when the operator supports the main body case with one hand, the intermediate portion provided with the key input means is wider than the grip portion, so the operator holds only the grip portion, It does not have the middle part.

Therefore, in such a state, if the user tries to operate the key input means with the finger of the hand holding the grip, usually the tip of the index finger or the middle finger, the key is located at the middle part closer to the head than the grip. Since there is an input means and the middle part is not hidden by the palm, a quick and accurate key input operation can be naturally performed with the fingertip of the hand holding the main body case.

Further, in this case, since the width of the intermediate portion is wider than that of the grip portion, the width of the key input means provided in the intermediate portion in the width direction of the main body case is different from that of the key input means provided in the grip portion. May be wider than the interval. In this way, even if the distribution range of the keys is widened, the number of keys remains small and only the interval between the keys is widened.
In operation with the fingertip of the hand holding the main body case, mistakes in pressing with an adjacent key are unlikely to occur, key operation can be performed more reliably, and work efficiency is good.

Further, in order to more reliably perform an operation with the fingertip of the hand supporting the main body case, the arrangement area of the key input means provided in the intermediate portion and the grip portion are separated. You may do it. If the grip portion and the arrangement area of the key input means are adjacent or close to each other, it may be difficult to perform an operation with the fingertip of the hand supporting the main body case. Preferably, it is completely separated from the part.

BEST MODE FOR CARRYING OUT THE INVENTION

[First Embodiment] FIG. 1 is a perspective view of a bar code reader handy terminal 2 as an optical reading terminal device to which some of the above-mentioned inventions are applied, and FIG. 2 is a front view.

The main body case 4 of the bar code reader handy terminal 2 comprises a head 6, a grip portion 8 and an intermediate portion 10. The grip 8 is narrower than the head 6,
An intermediate portion 10 is connected between the grip portion 8 and the head portion 6 in a tapered shape. The head 6 is provided with a reading port 12 eccentrically located on the abdominal surface 4 a side of the main body case 4, a liquid crystal display unit 14 as display means is provided on the back surface 4 b side of the head 6,
A key group 18 and 20 are provided on the back surface 4b side of the device, and a key group 16 as input operation detecting means is provided on the back surface 4b side of the intermediate portion 10.

The key group 16 provided in the intermediate unit 10
Has eight round keys arranged in two rows and four columns. Key group 18 provided on the gripping part 8 adjacent to the intermediate part 10
Has six round keys arranged in two rows and three columns.
The key group 20 provided on the gripping portion 8 on the opposite side to 0 has nine rectangular keys arranged in three rows and three columns.

The interval between the keys of the key group 16 arranged in the intermediate portion 10 is such that the intermediate portion 10 is wider than the grip portion 8 in the width direction, so that the key group 1
The key interval is wider than 8,20. The configuration inside the main body case 4 of the bar code reader handy terminal 2 is shown in a functional block diagram of FIG. The bar code reader handy terminal 2 is provided with a microprocessor 22 for controlling the functions of the entire apparatus, a light emitting diode 24 for illuminating the bar code B, a bar code reader 26 as an optical reader, a liquid crystal display 14, The key group 16, 1
A keyboard 30 comprising a trigger switch 28 on the side of the main body case 8 and 20, a communication unit 32 for optical communication with a host computer as a receiving means and a transmitting means, and a ROM or a RAM for storing master data to be described later. The memory 34 stores a processing program and temporarily stores data when the program is executed. The memory 34 counts time and calculates the current date and time. And a buzzer 38 for notifying the operator of the completion of the reading operation, an error or an abnormality.

The microprocessor 22 is supplied with electric power from a main battery 42 and a sub-battery 44 via a power supply controller 40. The power supply control unit 40 supplies power to the entire microprocessor 22 and peripheral circuits when a power key (ON) is pressed, or a part of the microprocessor 22 and peripheral circuits when no reading operation is performed for a long time. The power output to a part of the circuit is stopped to suppress the consumption of the main battery 42.

The main battery 42 is a storage battery, and when the bar code reader handy terminal 2 is set on the table 60, power is supplied through a terminal 46 that contacts a power supply terminal of a charging section 62 of the table 60. Supplied and charged.
The sub battery 44 is a backup storage battery, and is charged by the main battery 42.

When the operator turns on the trigger switch 28 and turns the reading port 12 toward the bar code B, the reflected light from the bar code B illuminated by the illumination light-emitting diode 24 passes through the imaging lens 48. Through this, an image is formed on the optical sensor 50 in which the light receiving elements are linearly arranged in one line. The optical sensor 50, which photoelectrically converts and reads the image of the barcode B, outputs to the barcode reading unit 26 as an electric signal representing an image pattern. The barcode reading section 26 binarizes the electric signal, reads the signal with the microprocessor 22, and converts the signal into information represented by the barcode B, for example, a product code.

For the bar code reader handy terminal 2 placed on the table 60, the bar code reader handy terminal 2 is communicated with the host computer 70.
Optical communication is performed bidirectionally via the communication unit 32 and the communication unit 64 of the table 60. The entry / exit information managed by the host computer 70 is transmitted by the host computer 70 to the barcode reader handy terminal 2 through two-way communication, and stored in the memory 34. The numerical information on the product code stored in the memory 34 corrected by the operation from the keyboard 30 is transmitted to the host computer 70 by two-way communication.

Next, FIG. 4 shows a flowchart of a quantity changing process among various processes executed by the microprocessor 22. In this quantity change processing, the number of incoming and outgoing goods of each product received from the host computer 70 is displayed on the liquid crystal display unit 14, and the operator confirms whether the number of incoming and outgoing goods matches the actual number of incoming and outgoing goods. If so, this is a process of correcting with the keyboard 30 of the bar code reader handy terminal 2.

When the quantity change processing is started, first, it is determined whether or not the bar code B has been read and the decoding has succeeded (S100). This is because, when the operator turns on the trigger switch 28, the lighting light emitting diode 2 is turned on.
4 irradiates the bar code B with light, the optical sensor 50 receives the reflected light, and the signal is determined by the microprocessor 22 decoding the signal via the bar code reading unit 26. You.

If the bar code B is read (S100
Then, when the bar code reader handy terminal 2 was previously set on the table 60, the bar code reader handy terminal 2 was sent from the host computer 70 to the memory 3
The product code represented by the bar code B is searched from the master data of the number of incoming and outgoing goods for each product stored in the storage device 4 (S110). When the search is completed, the product name corresponding to the product code and the number of entries and exits are displayed on the liquid crystal display unit 14 (S120).

For example, as shown in FIG. 2, "Product Name Onigiri" and "Number 10" are displayed. Next, it waits for a key input (S130). Here, when the operator compares the display content of the liquid crystal display unit 14 with the actual number of commodities and finds that the numerical value of the master data is different, the operator presses a numeric key, “+” Using the key and the "-" key, the displayed "quantity 10"
Correct the value of to the correct value. In this case, instead of directly inputting a correct numerical value, a difference between the correct numerical value and the displayed numerical value is input. The “+” key indicates a numerical value increase key, and the “−” key indicates a numerical value decrease key.

For example, if the actual number of “commodity rice balls” is “12”, the difference “2” is changed to “2” of the numeric keypad to correct “10” to “12”. This is done by pressing the key. Subsequently, the correction is made in the direction of increasing, so the "+" key is pressed. By inputting the "+" key, a process of increasing the quantity by the input numerical value is performed (S140). That is, the content of the display data temporarily set in the memory 34 is corrected to “number 12”, and at the same time, the display on the liquid crystal display unit 14 also changes to “product name rice ball” and “number 12”.

Conversely, if the actual number of “commodity rice balls” is “9”, the difference “1” is changed to “1” in the numeric keypad to correct “10” to “9”. This is done by pressing the key. Subsequently, since the correction is performed in the direction of decreasing, the "-" key is pressed. By inputting the "-" key, a process of reducing the quantity by the input numerical value is performed (S1).
50). That is, the content of the display data temporarily set in the memory 34 is corrected to “number 9”, and at the same time, the display on the liquid crystal display unit 14 also changes to “product name rice ball” and “number 9”.

Next, the operator presses an enter (ENT) key to inform the microprocessor 2 that the correction processing has been completed.
Inform 2 As a result, of the master data in the memory 34, “2” is added to the quantity “10” of “goods onigiri”, or “1” is subtracted, and corrected to “12” or “9”, The corrected master data is newly stored in the memory 34 (S160).

Next, it is determined whether or not the quantity changing process is completed (S170). If the operator starts reading the barcode B of the next product by operating the trigger switch 28 ("NO" in S170). ), The above-described processing is started again from step S100. If any key indicating the end of the quantity change process is pressed ("YE" in S170).
S "), the quantity change process ends.

In the first embodiment, as described above, when the operator corrects the quantity, the operator only has to input the difference from the actual numerical value. Normally, the difference between numerical values in entry / exit management etc. is not large, and it is at most about 1-3,
The operator can deal with most cases by searching for necessary keys from the keys of "1", "2", and "3". Therefore, as in the conventional case where all of the keys are entered from the beginning, a large number of keys widely distributed (keys of “0” to “9” and one of the enter keys)
Since the number of keys is small and the key group 16 is located as a group of keys 16 in the middle part 10 as compared with the case of searching and pressing from one key), the moving range of the fingertip is sufficiently narrow. For this reason, even with the fingertip of the hand that supports the bar code reader handy terminal 2 and has a very low degree of freedom of movement, the keys “1”, “2”, “3”, the increase key, the decrease key, and the enter key With a maximum of six keys, the number of keys is small and the moving range of the fingertip is limited, so that the keys can be pressed sufficiently quickly and accurately, and the correction work is efficient.

Also, "1", "2", "3", "ENTER", "ENT",
In the key group 16 in which the “+” and “−” keys are present, a smaller number of keys are located in the wide intermediate portion 10 compared to the grip portion 8 in which the other key groups 18 and 20 are arranged. Since the keys are arranged and the interval between the keys is sufficiently wide, the target key and the adjacent key can be operated accurately without being pressed by mistake.

As described above, the main body case 4 of the bar code reader handy terminal 2 has a tapered intermediate portion 10 between the head 6 and the grip portion 8 which is wider than the grip portion 8.
, And “1”, “2”, “3”,
It is formed in a state where a key group 16 in which keys of “ENTER”, “+” and “−” are present is arranged.
For this reason, when the operator grips the main body case 4 with one hand H as shown in FIG. 5, the intermediate portion 10 is tapered and wide, so that the grip portion 8 having the thinnest shape can be naturally held. Become. Therefore, the key group 16 of the intermediate unit 10 is not hidden by the palm of the hand H as compared with the key groups 18 and 20 of the grip unit 8, and the key group 16 of the intermediate unit 10 is Since the operation can be easily performed with the fingertip of the index finger F1 or the middle finger F2 of the present hand H, the operator can naturally perform quick and accurate key input operation.

In the example shown in FIG. 2, the power key (ON) and the "0" key are included in the key group 16 of the intermediate unit 10, but they are not directly related to the correction. Can be eliminated from the device, the number of keys is reduced, and the operation can be performed more accurately. In the first embodiment, steps S100, S110, and S120 by the microprocessor 22 correspond to processing as a display unit, and step S130 corresponds to processing as an input operation detecting unit.
Steps S140, S150, and S160 correspond to the processing as the correction unit.

[Second Embodiment] FIG. 6 is a front view of a bar code reader handy terminal 202 according to a second embodiment. The second embodiment is different from the first embodiment in that an intermediate portion 210 connecting the head 206 and the grip portion 208 includes an up (UP) key 212, a down (DOWN) key 214, and an enter (ENT) key. The key is located.

The up key 212 and the down key 214
As a result, a quantity change process as shown in FIG. 7 is performed. In this processing, steps S300 to S330, S360, and S370 other than steps S340 and S350 are respectively performed in steps S100 to S130 and S370 shown in FIG.
The processing is the same as the processing of S160 and S170.

In step S330, when the operator compares the display content of liquid crystal display unit 218 with the actual number of products and finds that the numerical values of the master data are different, the operator raises the value. By pressing the key 212 or the down key 214, the number displayed on the liquid crystal display unit 218 is increased or decreased, and the numerical value displayed on the liquid crystal display unit 218 is corrected to an actual numerical value.

When the up key 212 is pressed, the number displayed on the liquid crystal display 218 is incremented by one (S34).
0) When the down key 214 is pressed, the number displayed on the liquid crystal display unit 218 is decremented by one (S35).
0). Thus, the correction is made by pressing the up key 212 or the down key 214 until the difference becomes “0”.

For example, when the actual number of “commodity rice balls” is “12”, the up key 212 is pressed twice to increase the difference “2”, and the process proceeds to step S34.
“0” is executed twice, and “number 10” displayed on the liquid crystal display unit 218 is changed from “number 11” to “number 12”.

Conversely, if the actual number of “commodity rice balls” is “9”, the down key 214 is pressed once to reduce the difference “1”, and a step S350 is performed.
Is executed once, and “number 10” displayed on the liquid crystal display unit 218 is changed to “number 9”.

If the display on the liquid crystal display 218 matches the actual numerical value, the operator then presses the enter (ENT) key 216
To inform the microprocessor 22 that the correction process has been completed. As a result, in the master data in the memory 34, the quantity of “product onigiri” becomes “1”.
The data is corrected to “2” or “9”, and the corrected master data is newly stored in the memory 34 (S360).

According to the second embodiment, as described above, when the operator corrects the quantity, the difference from the actual numerical value is calculated by using the up key 212, the down key 214, and the enter key 2.
What is necessary is just to input with three keys of 16. Normally, the difference in numerical values in entry / exit management is not large, and at most 1 to 3
Since it is up to about, the operator presses the up key 212
Alternatively, the down key 214 may be pressed once to three times, and almost all cases can be dealt with with extremely few operations.

Therefore, since the number of keys is smaller than that in the first embodiment, the moving range of the fingertip is further narrowed. For this reason, even if the fingertip of the hand supporting the optical reading terminal device and having a very low degree of freedom of movement, the up key 21
2, up to three small keys, the down key 214 and the enter key 216, have a sufficiently limited range of movement of the fingertip, so that the keys can be pressed more quickly and accurately, and the correction work is efficient. Becomes

Further, similarly to the first embodiment, the main body case 204 of the bar code reader handy terminal 202 is provided.
Between the head 206 and the grip 208
A tapered intermediate portion 210 having a wider width is provided, and an up key 212, a down key 214, and an enter key 216 are arranged in the intermediate portion 210. Therefore, as in the case of FIG. 5, when the operator holds the main body case 204 with one hand H,
8 naturally. Therefore, the intermediate part 210
The up key 212, the down key 214 and the enter key 216 are not hidden by the palm of the hand H as compared with the key group existing in the gripper 208, and the up key 212, the down key 214 and the enter key The key 216 is a bar code reader handy terminal 20.
2 can be easily operated with the fingertip of the index finger F1 or the middle finger F2 of the hand H supporting the hand 2, and the operator can naturally perform quick and accurate key input operation.

Further, the number of the up key 212, the down key 214, and the enter key 216 provided in the intermediate portion 210 for changing the quantity is smaller than in the case of the first embodiment. The operation with the fingertip of the hand H of the user is further facilitated.

In the second embodiment, steps S300, S310 and S320 by the microprocessor 22 correspond to processing as display means, step S330 corresponds to processing as input operation detecting means, and steps S340 and S350. Steps S360 and S360 correspond to the processing as the correction means.

[Others] In the bar code reader handy terminal 2 according to the first embodiment, “1”, “2”,
After pressing the numeric key of “3”, the “+” and “−” keys were required to notify the microprocessor 22 of the increase / decrease, but in step S130, the numeric key was pressed after the “−” key was pressed. If it is determined that the number is to be reduced by pressing the number, and if it is determined that the number is to be increased by simply pressing the numeric key,
Since the "+" key can also be eliminated from the key group 16 of the intermediate unit 10, the number of keys is reduced, and a quicker and more accurate correction operation can be performed.

In the bar code reader handy terminal 202 of the second embodiment, the up key 212 and the down key 214 are independent of each other as shown in the left plan view and the right vertical sectional view in FIG. Although it is a push button type key, as shown in FIG. 8B, a seesaw type up key 312 and down key 314 which are connected and integrated inside the main body case 304 may be used. By doing so, the number of parts is reduced, leading to cost reduction.

Further, as shown in FIG. 8C, the up key and the down key may be integrally formed as a slide switch 416. In this case, the body case 40
