Description

An embodiment of the present invention relates to, for example, a product data processing apparatus including a printer for issuing a receipt.

Conventionally, a POS (point of sales) terminal having a scanner for reading product code information and a printer for issuing receipts is known. In order to hold the product code information over the scanner, a relatively large work space for handling the product is required on the front side of the scanner. Therefore, in this POS terminal, the scanner is placed on top of the printer, and the space in front of the printer is used as a work space.

On the other hand, when the receipt roll of the printer is exhausted, or when jam occurs in the printer, the printer is pulled out from the housing of the POS terminal to the work space in front of the printer, and the receipt roll is replaced or jam processing is performed.

Japanese Unexamined Patent Publication No. 2014-38649

Receipt roll replacement and jam processing work are often performed with the customer who purchases the product waiting, and it is desirable to complete the work in the shortest possible time and promptly hand over the receipt to the customer.

However, when the printer is pulled out to the work space and the work is performed like the above-mentioned conventional POS terminal, the receipt can be issued after the printer is returned to the original position in the housing after the work is completed. Time will be longer by that amount. Further, if the jam is not resolved when the printer is returned to the original position, it is necessary to pull out the printer again to perform the jam processing work, which is complicated and takes a lot of time.

Therefore, it is desired to develop a product data processing apparatus capable of promptly issuing a receipt after the receipt roll is replaced or the jam processing work is completed.

The product data processing device according to the embodiment includes a printer unit, a housing in which the printer unit is retractably housed, an open / close sensor for detecting an open / closed state of a cover of the printer unit, and a control unit. When the control unit detects that the cover is closed via the open / close sensor with the printer unit pulled out from the housing, if the printer unit can issue a receipt, the control unit permits the printer unit to issue a receipt. do.

Hereinafter, embodiments will be described in detail with reference to the drawings.
As shown in FIG. 1, the product data processing device 100 (hereinafter, simply referred to as the device 100) according to the embodiment has a housing 10 having a front surface 11 facing a store clerk who sells the product. A back cover 20 is detachably attached to the back side of the housing 10. The back cover 20 has an inclined back surface 21 facing a passage through which a customer who purchases a product passes. The back surface 21 functions as a display surface for displaying various information for the customer.

It is necessary to secure a relatively wide work space S on the front surface 11 side of the housing 10 for the store clerk to handle the product to be read. The front surface 11 of the housing 10 is formed on a flat surface (without protrusions) along the vertical direction in order to make the work space S as wide as possible. When the front surface 11 of the housing 10 is set to a flat vertical surface, the product does not hit the protrusions when the barcode of the product is held over the reading window 32 of the scanner unit 30, and workability can be improved.

A protection guide 110 is attached between the work space S and the housing 10 to prevent the basket containing the product from colliding with the housing 10 of the device 100. The protection guide 110 is provided so as to project upward from the upper surface 121 of the table 120 on which the basket is placed. The shape of the protection guide 110 is not limited to the one shown in the figure and may be any shape. Further, the protection guide 110 is not an essential configuration.

A scanner unit 30 and a printer unit 40 are provided side by side in the housing 10. In the present embodiment, the printer units 40 are arranged under the scanner unit 30 and housed and arranged in the housing 10. Therefore, the housing 10 of the device 100 has a relatively vertically long structure.

The scanner unit 30 has a front surface 31 that can be arranged flush with the front surface 11 of the housing 10. A reading window 32 for reading a bar code of a product is provided on the front surface 31 of the scanner unit 30. The scanner unit 30 can be arranged in a posture in which the reading window 32 is substantially parallel to the front surface 11 of the housing 10, and can be arranged in a posture in which the reading window 32 is inclined downward with respect to the front surface 11 of the housing 10. be. That is, the scanner unit 30 is provided with a tilt mechanism (not shown) that tilts the reading window 32 to an arbitrary angle.

The printer unit 40 is provided so as to be removable with respect to the accommodating portion 12 provided below the housing 10. That is, a rectangular box-shaped accommodating portion 12 for accommodating the printer unit 40 so that it can be inserted and removed is provided below the scanner unit 30. The front side of the accommodating portion 12 is open to the front surface 11 of the housing 10. As shown in FIGS. 2 and 3, two rails 43 and 43 (only one of which is shown) that support the bottom surface of the printer unit 40 are provided on the bottom of the accommodating portion 12.

As shown in FIGS. 2 and 3, the two rails 43, 43 are provided so as to be retractable from the accommodating portion 12 toward the work space S in front of the housing 10. The two rails support the printer unit 40 at a position where the printer unit 40 is pulled out from the front surface 11 of the housing 10 to the front side (work space S side) in the illustrated state of being pulled out from the housing 10. Further, when the printer unit 40 is pushed into the accommodating portion 12, the two rails 43, 43 shrink while supporting the bottom surface of the printer unit 40 and are accommodated in the accommodating portion 12 together with the printer unit 40.

A receipt roll (not shown) is housed and arranged in the printer unit 40. The receipt roll is, for example, a roll of elongated receipt paper having a width of about several tens of millimeters and a length of several tens of meters. The front surface 41 of the printer unit 40 is provided with a discharge port 42 for discharging the receipt separated from the receipt roll.

Further, an opening 44 for accessing the inside of the printer unit 40 is provided in the upper part of the printer unit 40 for exchanging the receipt roll and jamming. The opening 44 is provided with a cover 46 that opens and closes the opening 44. FIG. 3 shows a state in which the printer unit 40 is pulled out from the accommodating portion 12 of the housing 10 and the cover 46 is opened.

The accommodating portion 12 accommodating the printer unit 40 is provided at a position separated above the lower end of the housing 10. As a result, when the receipt roll is fed to the printer unit 40, the printer unit 40 can be largely pulled forward from the accommodating portion 12. That is, since the above-mentioned protection guide 110 is provided on the front surface 11 side of the housing 10, the accommodation unit 12 is provided at a position higher than the height at which the protection guide 110 projects upward from the upper surface of the table 120. The printer unit 40 pulled out from 12 does not interfere with the protection guide 110.

Receipt rolls with a relatively large diameter are used in order to reduce the number of replacements. Therefore, the printer unit 40 having the receipt discharge port 42 on the front surface 41 has a predetermined size in the radial direction of the receipt roll, that is, in the vertical direction and the front-rear direction of the printer unit 40. Therefore, in the present embodiment, the printer unit 40 is arranged below the housing 10, and the back side of the printer unit 40 is projected toward the inner surface of the back cover 20.

That is, in the present embodiment, the printer unit 40 having a larger dimension in the front-rear direction than the scanner unit 30 is arranged below the housing 10. Then, the scanner unit 30 was arranged on the printer unit 40. Further, the front surface 31 of the scanner unit 30 and the front surface 41 of the printer unit 40 are arranged substantially flush with the front surface 11 of the housing 10. Therefore, the back cover 20 that covers the back side of the housing 10 is formed into a wedge shape that is inclined downward toward the back side as shown in the figure.

By arranging the relatively large printer unit 40 at the bottom and the relatively small scanner unit 30 at the top in this way, the housing 10 can be stably installed.

As shown in FIG. 1, the device 100 has an operation panel 50 including a control board (not shown) equipped with a processor. The control board of the operation panel 50 functions as a control unit that controls the device 100. In addition, the device 100 optionally includes a keyboard 60 attached to the side surface of the operation panel 50 and a sub-panel 70.

The operation panel 50 has an operation screen 51 on the front side (clerk side) and is rotatably attached to the upper end of the housing 10. That is, the operation panel 50 is attached to the upper end of the housing 10 in a state where the orientation of the operation screen 51 can be changed. The operation panel 50 is arranged further above the scanner unit 30. The operation panel 50 is provided with a touch sensor on the operation screen 51 capable of displaying an image, and various input operations can be performed by a clerk touching various buttons displayed on the operation screen 51 with a finger.

The keyboard 60 includes a card reader 61. The keyboard 60 has a multiplication key, a subtotal key, and the like. The card reader 61 reads the data recorded on the credit card or the point card. Although FIG. 1 shows a card reader capable of reading a magnetic card, it may be capable of reading a contact type IC card or a non-contact type IC card.

The sub-panel 70 is attached so as to project to the side of the housing 10 via the arm 72. The arm 72 rotatably supports the sub-panel 70 in the illustrated posture in which the operation surface 71 of the sub-panel 70 is directed toward the customer and the posture in which the operation surface 71 is directed toward the store clerk. The sub-panel 70 can be used not only as a terminal operated by a customer, but also as an auxiliary terminal operated by a clerk.

FIG. 4 is a block diagram showing a circuit configuration of a main part of the printer unit 40 described above. The printer unit 40 is connected to the operation panel 50 and issues a receipt in response to a print request from the operation panel 50.

The processor 81, the main memory 82, the print head 83, the LED lamp 84, the receipt roll sensor 85, the jam sensor 86, the accommodation sensor 87, the open / close sensor 88, and the interface unit 89 are connected via the transmission line 90.

In the printer unit 40, a computer that performs information processing for controlling the printer unit 40 is configured by connecting a processor 81 and a main memory 82 via a transmission line 90. The printer unit 40 may further include an auxiliary storage unit connected to the transmission line 90, and the computer may be configured by including the auxiliary storage unit as an auxiliary storage portion. As the auxiliary storage unit, for example, EEPROM (registered trademark) (electric erasable programmable read-only memory) is used. As the auxiliary storage unit, an HDD (hard disk drive), an SSD (solid state drive), or the like can also be applied.

The processor 81 corresponds to the central part of the computer. The processor 81 controls each unit in order to realize various functions as the printer unit 40 according to the operating system, firmware, and application program.

The main memory 82 corresponds to the main memory portion of the computer. The main memory 82 includes a non-volatile memory area and a volatile memory area. The main memory 82 stores the operating system, firmware and application programs in the non-volatile memory area. Further, the main memory 82 may store data necessary for the processor 81 to execute a process for controlling each part in a non-volatile or volatile memory area. The main memory 82 uses the volatile memory area as a work area where data is appropriately rewritten by the processor 81.

The print head 83 prints an arbitrary image or character on the receipt roll under the instruction of the processor 81. The print head 83 is, for example, a well-known thermal head. The print head 83 is attached to the inside of a cover 46 provided on the upper part of the printer unit 40. That is, the print head 83 can be pulled out from the accommodating portion 12 together with the printer unit 40. Therefore, even when the printer unit 40 is pulled out from the accommodating portion 12, printing on the receipt paper is possible as long as the cover 46 is closed.

The LED lamp 84 functions as a notification means for notifying the operator of the state of the printer unit 40. The LED lamp 84 is provided on the front surface 41 of the printer unit 40. The LED lamp 84 is controlled to light in green when the printer unit 40 is in a printable state, and is controlled to light in red when the printer unit 40 is in a print prohibition state.

The receipt roll sensor 85 detects that the receipt roll is normally mounted in the printer unit 40. The jam sensor 86 detects that the receipt paper is jammed in the printer unit 40. The receipt roll sensor 85 and the jam sensor 86 function as an abnormality sensor for detecting an abnormality in the printer unit 40.

The accommodation sensor 87 detects the accommodation state of the printer unit 40 in the housing 10. That is, the accommodation sensor 87 detects that the printer unit 40 is normally mounted in the accommodation unit 12 of the device 100. Specifically, the accommodation sensor 87 detects that the printer unit 40 is attached to the accommodation unit 12, and the printer unit 40 is in the state of FIGS. 2 and 3 pulled out from the housing 10 of the apparatus 100. Detect that.

The open / close sensor 88 detects the open / closed state of the cover 46 of the printer unit 40. Specifically, the open / close sensor 88 detects that the cover 46 is arranged at a closed position that closes the opening 44 of the printer unit 40, and the cover 46 opens the opening 44 fully. Detects that it is placed in a position.

The cover 46 can be opened as shown in FIG. 3 with the printer unit 40 pulled out to the position shown in FIG. In other words, the cover 46 cannot be opened when the printer unit 40 is housed in the housing portion 12 of the housing 10 of the device 100.

An operation panel 50 is connected to the interface unit 89 via, for example, a communication cable. The interface unit 89 transmits and receives various data to and from the operation panel 50. As the interface unit 89, a ready-made device conforming to a well-known standard such as USB (universal serial bus) can be used.

The transmission line 90 includes an address bus, a data bus, a control signal line, and the like, and transmits data and control signals transmitted and received between the connected units.

Hereinafter, the first operation example of the printer unit 40 described above will be described with reference to FIG.

When the printer unit 40 is set to an operating state capable of issuing a receipt in response to a request from the operation panel 50, the processor 81 will be described below according to the firmware or application program stored in the main memory 82. Execute information processing.

As Act1, the processor 81 determines whether or not the receipt paper is out. Whether or not the receipt paper is out is determined by providing a sensor for detecting the receipt paper in the path for transporting the receipt paper and judging from the output of this sensor. Alternatively, it may be determined whether or not the receipt paper is out by checking the remaining amount of the receipt paper of the receipt roll housed and arranged in the printer unit 40 and comparing it with a preset threshold value. In this case, the remaining amount of the receipt paper is calculated by, for example, after exchanging with a new receipt roll, counting the number of receipts issued by the apparatus 100, and multiplying the average length of the preset receipts by the number of receipts issued. Can be done. When the processor 81 determines that the receipt paper has run out in Act1 (Act1; YES), the processor 81 proceeds to Act3.

When it is determined by Act1 that the receipt paper is not out (Act1; NO), the processor 81 detects the presence or absence of jam through the jam sensor 86 as Act2, and the printer unit 40 jams the receipt paper. Determine if you are doing it. When the processor 81 determines that the jam has occurred in Act2 (Act2; YES), the processor 81 proceeds to Act3. On the other hand, when it is determined that no jam has occurred in Act2 (Act2; NO), the processor 81 returns to Act1.

As Act3, the processor 81 first prohibits printing on the receipt paper by the printer unit 40. Next, the processor 81 turns on the LED lamp 84 in red as Act 4, and transmits a signal for displaying an error to the operation panel 50 via the operation screen 51. At this time, the error display is a content for notifying the operator of the receipt roll out or the occurrence of jam.

Then, the processor 81 determines whether or not the printer unit 40 is pulled out from the accommodating portion 12 of the housing 10 for the receipt roll exchange or jam processing as Act5. At this time, the processor 81 detects whether or not the printer unit 40 is in a state of being pulled out to the drawer position shown in FIG. 2 via the accommodation sensor 87. When it is determined in Act 5 that the printer unit 40 is in the pulled-out state (Act 5; YES), the processor 81 proceeds to Act 6.

As Act6, the processor 81 determines whether or not the cover 46 of the printer unit 40 is opened in the state shown in FIG. 3 via the open / close sensor 88. After determining that the cover 46 is in the open state in Act 6 (Act 6; YES), as Act 7, the processor 81 determines whether or not the cover 46 of the printer unit 40 is closed via the open / close sensor 88. do. Until the processor 81 determines that the cover 46 has been closed at Act 7 (Act 7; NO), that is, when the cover 46 is open, the operator performs receipt roll replacement work and jam processing work.

When it is determined by Act7 that the cover 46 is closed (Act7; YES), the processor 81 normally mounts the receipt roll as Act8 at a predetermined position in the printer unit 40 via the receipt roll sensor 85. Judge whether or not. Further, when it is determined by Act7 that the cover 46 is closed (Act7; YES), the processor 81 confirms that there is no jam of the receipt paper in the printer unit 40 via the jam sensor 86 as Act9.

Then, when it is determined in Act8 that the receipt roll is normally attached and there is no jam in Act9 (Act8; YES, Act9; YES), the processor 81 is set as Act10 in Act3. The printing prohibition is canceled, printing on the receipt roll is permitted, and the process proceeds to Act11.

As Act 11, the processor 81 turns on the LED lamp 84 in green, and transmits a signal for terminating the error display displayed via the operation screen 51 to the operation panel 50. As a result, the LED lamp 84 lights up in green.

In this state, the printer unit 40 is still pulled out to the position shown in FIG. 2, but is in a state where printing on the receipt roll is possible and a receipt can be issued. That is, according to the first operation example, if the printer unit 40 is in a state where the receipt can be issued and the cover 46 is closed, the receipt can be issued with the printer unit 40 pulled out to the customer. Receipts can be issued promptly.

Further, according to the first operation example, even when the printer unit 40 is pulled out, if the cover 46 is closed with no abnormality in the printer unit 40, the LED lamp 84 for notifying that the receipt can be issued is provided. Light up in green. Therefore, the operator can determine that the printer unit 40 can operate normally before accommodating the printer unit 40 in the accommodating unit 12, and can finish the receipt roll replacement work and the jam processing work at an early stage. You can find out at. As a result, it is not necessary to push the printer unit 40 into the accommodating unit 12 and then check the operation, and the receipt can be promptly issued to the customer.

Next, a second operation example of the printer unit 40 will be described with reference to FIG. Since Act1 to Act11 are substantially the same as the first operation example described above, most of the description thereof will be omitted here.

In the second operation example, the processor 81 determines that there is a receipt roll in Act8, determines that there is no jam in Act9, and then cancels the print prohibition set in Act3 as Act10 and permits the issuance of only one receipt. do. At this time, the processor 81 permits the issuance of only one receipt based on the code information of the product scanned immediately before prohibiting printing by Act 3, and proceeds to Act 11.

Then, the processor 81 turns on the LED lamp 84 in green as Act 11, and transmits a signal for ending the error display displayed via the operation screen 51 to the operation panel 50, and proceeds to Act 12. As Act 12, the processor 81 issues only one receipt and proceeds to Act 13.

After that, the processor 81 prohibits printing on the receipt paper by the printer unit 40 as Act 13, and proceeds to Act 14. Then, as Act 14, the processor 81 determines whether or not the printer unit 40 is accommodated in the accommodating portion 12 via the accommodating sensor 87, and when the printer unit 40 is accommodated in the accommodating portion 12 (Act 14; YES). Then proceed to Act15.

Finally, as Act 15, the processor 81 cancels the print prohibition state set in Act 13, and returns to Act 1.

As described above, according to the second operation example, since the issuance of only one receipt is permitted with the printer unit 40 pulled out, wait for the completion of the receipt roll replacement work or the jam processing work. Receipts can be issued promptly to customers who are present.

Further, according to the second operation example, after issuing the receipt only once, printing by the printer unit 40 is prohibited until the printer unit 40 is accommodated in the accommodating unit 12, so that the printer unit 40 is in a pulled out state. It is possible to prevent the process from being continued as it is.
