Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the structure of a checkout lane. A barcode scanner 13 supported by a support member 12 is arranged on a soccer table 11, and an operation unit 14 is placed on the barcode scanner 13. By operating the barcode scanner 13 and the operation unit 14, the merchandise purchased by the customer is registered and the payment is made. The operation unit 14 includes an operation panel 14a including a display and a touch panel disposed on the display, and a keyboard 14b disposed on the side of the operation panel 14a.
It is constituted by.

FIG. 2 is a block diagram showing the configuration of the entire system. The operation unit 14 is provided with a CPU (central processing unit) 15 constituting a control unit main body, and the CPU 15 has a ROM (read / read) storing a control program. Only memory)
16, a RAM (random access memory) 17 provided with a memory used for various processes, a non-volatile memory 18 for storing setting information and the like, and the keyboard 14b are connected to each other.

A touch panel 141 of the operation panel 14a is connected to the CPU 15 via a decoder 19, and a liquid crystal display 142 of the operation panel 14a is connected to the CPU 15 via a liquid crystal driver 20.
A notification sound generating means including a buzzer driver 21 and a speaker 22 is connected. The decoder 19 calculates coordinates of a touch position based on a signal from the touch panel 141 and notifies the CPU 15 of the coordinates. Further, a height sensor 23 for detecting a height position of the operation panel 14a and an inclination sensor 24 for detecting an inclination of the operation panel 14a are connected to an I / O port of the CPU 15. Further, a communication driver 25 is connected to the CPU 15.

The operation unit 14 is connected to a POS terminal main body 27 for performing a product registration process from the communication driver 25 via an RS-232c interface 26. The bar code scanner 13 is connected to the POS terminal main body 27. The POS terminal main body 27 is connected via a network 28 to a host computer 29 having a file in which the price of each product, the product name and the like are stored.

The RAM 17 stores a table 17a shown in FIG. In the table 17a, a plurality of product items are assigned a number, a product item name, a packing form, and code information, and are classified and stored in a plurality of product groups. For example, the first merchandise group is a group in which merchandise with a high frequency of merchandise registration is collected, and has a group name of “priority”. The second product group is a group of products of leafy vegetables, and is given a group name of "leaf vegetables". The third product group is a group that collects products of root vegetables, and has a group name of “root vegetables”. The third product group is a group that collects products of root vegetables, and has a group name of “root vegetables”. The fourth product group is a group that collects the remaining vegetables and other products, and is named “vegetables and others”. The fifth merchandise group is a group of fruits merchandise, and is given a group name "fruit".

The packing form is information indicating the sales quantity, the sales amount, the sales size, and the like. For a commodity item having only one packing form, this information is set to “1”. Further, for example, for the product item “egg”, information indicating the size of each pack is used as packing form information.
It stores three packing form information of "M" and "S". Further, for example, for the product item “cucumber”, information indicating the number of each pack is used as packing form information, and for example,
Three pieces of packing form information “1”, “2”, and “5” are stored. For example, for the product item “watermelon”, information indicating the amount of each pack is used as packing form information, and, for example, three packing form information “1”, “」 ”, and“ １ ／ ”are stored. I have.

In this system, when the power of the POS terminal main body 27 is turned on, the POS terminal main body 27 is turned on.
Makes an inquiry about the setting information of the operation panel 14a to the host computer 29. In response to this, the host computer 29 reads the information of the product group name and each product item belonging to the product group from the file, that is, the product item name, package Read each information of form and code
It is transmitted to the S terminal main body 27.

When the POS terminal main body 27 receives the product group name and the information of each product item belonging to the product group from the host computer 29, it transmits it to the CPU 15 of the operation unit 14, and the CPU 15 receives the information and stores it in the RAM 17. A table having contents as shown in FIG. 3 is formed. Then, the liquid crystal driver 20 is driven based on the contents of the table, and the key button image 31 of each product group name is displayed on the left side on the liquid crystal display 142 of the operation panel 14a as shown in FIG. A key button image 32 of each product item belonging to the group name "priority" is displayed, and a product information display area 33 for displaying the product item name, packing form information, and price is formed on the upper side. That is, when the power is turned on, the merchandise items of the merchandise group name “priority”, which are collections of merchandise items with high registration frequency, are always displayed. The key button image 31 of each product group name is displayed so that the key button image of “priority” can be distinguished from the key button images of other product group names. For example, the key button images of other product group names are The display is made inconspicuous gray, and only the "priority" key button image is displayed normally.

Since the information of the table to be set is obtained from the host computer 29, the product group name of the table and the content of the product item of each product group are changed, and the display content of the operation panel 14a is changed. This can be easily performed by information from the host computer 29. Therefore, it is possible to easily cope with a significant change in the sale product.

Next, the registration operation in this system will be described. When registering a bar-coded product, the bar code is read by the bar code scanner 13, and the product code is sent to the host computer 29 via the POS terminal main body 27. The host computer 29 reads the price of the product corresponding to the product code from the file and transmits it to the POS terminal main body 27. The POS terminal main body 27 performs a registration process based on the product code, the number, the price, etc., adds the price to the totaling unit, prints out the product name, the number, the price on a receipt and supplies the price to the CPU 15. Thereby, the CPU 15 displays the product name, the number, and the price in the product information display area 33 of the operation panel 14a.

In the case of a product such as fresh food without a bar code, the key button image 32 of each product item on the operation panel 14a is used to determine whether or not this product is a "priority" product item. Confirm. If there is, touch operation is performed on the key button image of the corresponding product item.

If there is no product, the key button image of the product group to which the product belongs is touch-operated. This allows
The CPU 15 is a key button image 32 of the item on the right.
Is switched to the key button image of each product item of the product group by performing a touch operation based on the content of the table 17a. For example, if the product is “watermelon”, the image of “fruit” is touched from the key button image of the product group on the left. As a result, the key button image of "fruit" is switched to the normal display, and the "priority" which was the normal display until then is displayed.
The key button image is switched to gray display. Further, the key button image 32 of the commodity item on the right is switched to a key button image belonging to the group “fruit”.

Since there is a key button image of the merchandise item "watermelon" here, this image is touch-operated.
Thus, the display on the operation panel 14a becomes the display shown in FIG. That is, since the product item "watermelon" has three packing form information, one selling, one half selling, and one quarter selling, the key button image 34 for designating each packing form information is displayed on the screen. Display below. In addition, a product item name “watermelon” is displayed in the product information display area 33. At this time, the CPU 15 operates the buzzer driver 2.
1 to generate a notification sound from the speaker 22 to notify the operator that registration has not been completed.

Here, when the key button image 34 for designating the packaging form information is touched, the CPU 15 transmits the code information of "watermelon" to the POS terminal main body 27, and the POS terminal main body 27 28 to the host computer 29. (Code information output means) Host computer 2
In step 9, the price of the product corresponding to the product code is read from the file and transmitted to the POS terminal main body 27.
The POS terminal main body 27 performs a registration process based on the product code, the number, the price, etc., adds the price to the totaling unit, prints out the product name, the number, the price on a receipt and supplies the price to the CPU 15. As a result, the CPU 15 sets the product name, the packing form, and the price in the product information display area 33 of the operation panel 14a as shown in FIG.
To be displayed. Further, the key button image 34 for designating the packing form information is deleted.

In the case of one packing form such as the commodity item “chestnut”, when the key button image of “chestnut” is touched, the CPU 15 transmits the code information to the POS terminal main body 27. . Therefore, in this case, the key button image 34 for designating the packing form information
This eliminates the need for touch operation.

Then, the CPU 15 returns the display state of the operation panel 14a to the initial screen shown in FIG. Further, the CPU 15 sets the key button image 3 of the product group name.
After the touch operation of No. 1, the display state of the operation panel 14a is returned to the initial screen shown in FIG. 4 also when the touch operation of the key button image 32 of each product item is not performed even after a predetermined time has elapsed.

Therefore, a key button image corresponding to a product with a high registration frequency is always displayed on the operation panel 14a with priority, so that when registering a product with a high registration frequency, the key button image 32 of the product item is touched. Registration can be performed in a single step of operation, and operability can be improved. In addition, since only the key button images of the product items belonging to the product group are displayed by specifying the product group, the number of keys to be displayed at a time is reduced, and accordingly,
It is easy to find the corresponding key button image, and the key operation can be facilitated.

Next, the operation when the operator touches the key button image will be described. When the operator touches the touch panel 141 of the operation panel 14a with a finger, the decoder 19 calculates the coordinates of the touch position, and
Notify U15. At this time, the CPU 15 controls the buzzer driver 21 to drive the speaker 22 to generate a notification sound in order to notify that the touch operation has been performed reliably. The CPU 15 controls the liquid crystal driver 20 to display the cursor image 41 on the liquid crystal display 142 immediately below the touch position, as shown in FIG. 7, and furthermore, if this position is the position of the key button image, A rectangular mark 42 is displayed to inform the operator that the button has been recognized as a target.

When the operator moves the finger while touching the touch panel 141 of the operation panel 14a, the decoder 19 calculates the coordinate movement of the touch position accompanying the movement of the finger and notifies the CPU 15 of the movement. Accordingly, the CPU 15 controls the liquid crystal driver 20 to move the cursor image 41 and the mark 42 according to the movement of the touch position. Therefore, the operator can always reliably recognize which key button is being operated,
Operability can be improved.

Then, the operator operates the touch panel 141
When the finger is released from and the touch operation is released, the CPU 15 specifies the key button image at the position where the finger is released by a signal from the decoder 19, reads out the code information of the product item corresponding to this key button image from the table 17a, and It is transmitted to the POS terminal main body 27. In addition, the buzzer driver 21 is controlled to drive the speaker 22 to generate a notification sound different from the sound when the touch panel 141 is touched. Thereby, the operator knows that the touch operation on the key button image has been completed.

As described above, since the touch operation is not determined as long as the touch operation is performed on the touch panel 141 and the touch position is moved in that state, even if the operator touches a different key button image by mistake, the operator does not release his finger. Move to the correct key button image position and then release your finger,
Erroneous operation can be reduced. In addition, since different notification sounds are generated when the operator touches the touch panel 141 with a finger and when the finger is released, the operator can reliably know the operation state of the operation panel 14a, and the operability is improved. Can be improved.

Next, parallax correction when touching the touch panel 141 will be described. As shown in FIG. 8, the operation unit 14 is mounted on a barcode scanner 13 so as to be freely rotatable in the vertical direction, and the support member 12 supporting the barcode scanner 13 has its lower part provided on the soccer table 11. The lower part is inserted into the flange part 43 formed in a cylindrical shape, and is fixed with screws 44.

The height sensor 23 in which, for example, six position sensors having a light source 45 and a light receiving sensor 46 as a pair are arranged at a predetermined interval in the lower part of the flange portion 43 is arranged. The height sensor 23 is a position sensor at a position where the support member 12 is inserted.
OFF because it does not reach the light receiving sensor 46 because it is shaded by 2
The light from the light source 45 reaches the light receiving sensor 46 and the position sensor at the position where the support member 12 is not inserted is turned on.

Accordingly, the CPU 15 detects the signals of the position sensors from the height sensor 23 to determine which position sensors are OFF and which position sensors are ON, so that the soccer table 11 can be used.
The height H2 from the floor on which is mounted to the center of the operation panel 14a of the operation unit 14 can be ascertained.
That is, the height data H2 for each ON / OFF state of each position sensor is set in the nonvolatile memory 18 in advance,
The corresponding height data H2 is read out from the non-volatile memory 18 to know which position sensor is OFF and which position sensor is ON. Further, data L1 of the horizontal distance between the center position of the operation panel 14a and the position of the operator's eye is also set in the nonvolatile memory 18. This distance data L1 is determined by the width of the soccer table 11 and the mounting position of the barcode scanner 13, and there is almost no individual difference, and therefore there is only one type.

The inclination sensor 24 is attached to the back side of the upper end of the operation unit 14, and detects the inclination α of the operation unit 14, that is, the operation panel 14a with respect to the horizontal line, to detect C.
The PU 15 is notified.

The host computer 29 is provided with a database storing information on the eye height H1 of each operator 47. For example, before the operator starts the registration work, the card insertion section of the POS terminal main body 27 can be used. POS terminal 27 reads the ID of the ID card and sends it to host computer 29. The host computer 29 reads the height data H1 of the eye position of the corresponding operator from the database based on the ID, and returns it to the POS terminal main body 27. The POS terminal main body 27 supplies the height data H1 to the CPU 15.

Accordingly, the CPU 15 operates in the non-volatile memory 1
8 to read the height data H2 and the distance data L1,
By acquiring the height data H1 from the S terminal main body 27 and acquiring the inclination α from the inclination sensor 24, first, the operator looks down the angle of view β of the operation panel 14a by β = tan ⁻¹ (H1−H2) / L1... (1) Then, the intersection angle θ between the normal line of the operation panel 14a and the line of sight of the operator is calculated by θ = 90 (deg) −α (deg) −β (deg) (2).

As shown in FIG. 9, the operation panel 14a is provided above the liquid crystal display 142 with a predetermined gap d.
The touch panel 141 having a thickness tc is disposed at a distance from the touch panel 141. For example, the thickness tc of the touch panel 141 is
Is 3 mm and the gap d is 2 mm, the relationship between the intersection angle θ and the parallax L is as shown in FIG. This is shown in FIG.
When the operator who looks at the operation panel 14a from the direction c attempts to perform a touch operation on the key button image displayed at the position B on the liquid crystal display 142, the touch panel 14
On 1, the key button image appears at the position A ′, so the operator touches the position A ′. However, the position A 'on the touch panel 141 corresponds to the position A on the liquid crystal display 142. Therefore, the CPU 15 erroneously determines that the key button image displayed at the position A on the liquid crystal display 142 has been operated. Become. This is a phenomenon that occurs because a parallax L, which is a difference between the position B and the position A, occurs on the liquid crystal display 142.

In order to prevent such an erroneous operation due to the parallax L, data obtained by digitizing the contents shown in FIG. Then, the parallax L is obtained from the intersection angle θ obtained by the above equation (2), and the CPU 15 determines the coordinates of the touch position obtained from the decoder 19 in consideration of the parallax L. In other words, the determination is made by correcting the parallax L in the vertical direction of the operation panel 14a. (Position coordinate determination means)
This allows the operator to set A ′ on touch panel 141
Even if the position is touched, the CPU 15 determines that the key button image at the B position on the liquid crystal display 142 has been operated, and prevents an erroneous operation. Thus, the touch operation on the key button image can be reliably performed.

In this embodiment, a CPU 15 is provided on the operation panel side, and the CPU 15
M17, nonvolatile memory 18, decoder 19, liquid crystal driver 20, keyboard 14b, buzzer driver 2
1, the connection of the height sensor 23 and the inclination sensor 24 has been described. However, the present invention is not necessarily limited to this, and as shown in FIG.
7, a decoder 19, a liquid crystal driver 20,
A keyboard 14b, a buzzer driver 21, a height sensor 23, and a tilt sensor 24 are connected to each other, and ROM, RA
