Description

[0001]
[Industrial application fields]
The present invention relates to a cash register, and more particularly, to a cash register printing mechanism that performs journal printing for issuing a receipt and recording a sales history.
[0002]
[Prior art]
Conventionally, a cash register or POS terminal used in a retail store or the like (hereinafter referred to as “money register”) has two printing devices arranged therein. This printing apparatus is a receipt printing apparatus for printing a receipt issued to a customer, and the other printing apparatus is a journal printing apparatus for printing a sales record. Conventionally, a roll sheet having the same or different width has been separately prepared for each printing apparatus.
[0003]
Here, if the same width is used for the receipt and the journal sheet, the trouble of managing and storing two types of roll sheets can be avoided. However, since the journal sheet is for recording the sales history, the items to be printed are different from the receipt. Only the sales details, which are information for sales management, are printed on the journal sheet. On the other hand, information items that are not printed on the journal sheet, such as the store name, the advertisement text, the amount received, and the change, are printed on the receipt. For this reason, it is more reasonable to use roll sheets having different widths for normal receipts and journal sheets. Conventionally, there are many examples of cash registers configured to handle different widths.
[0004]
In either case, the consumption of the roll sheet for receipt and journal is different due to the difference in the print information items, and the replenishment timing of the roll sheet for both does not match.
[0005]
[Problems to be solved by the invention]
Thus, the conventional cash register includes two printing devices, a receipt printing device and a journal printing device, and further, roll sheets of the same or different width for each printing device and two rolls.・ It was necessary to provide a seat storage unit inside. This not only made it difficult to reduce the size of the cash register, but also prevented the cash register from being lowered by the two printing devices that accounted for a large portion of the cost of the cash register.
[0006]
Further, since the replenishment timings of the two roll sheets do not match, each roll sheet must be replenished separately. During the roll sheet replenishment time, the customer was kept waiting, resulting in a decrease in service to the customer and an inefficient store operation. Furthermore, it was necessary to manage two different types of paper for receipt and journal.
[0007]
In view of the problems of such a conventional cash register, the present invention provides a cash register that contributes to the miniaturization, cost reduction, and high reliability of the cash register and is easy to maintain. To aim.
[0008]
[Means for Solving the Problems]
In order to solve the problems of the prior art, a cash register according to the present invention includes a printing unit that prints the details of sales on a roll sheet, and the roll sheet is separated into left and right parallel to the running direction. Separating one of the separated roll sheets as a receipt sheet and the other as a journal sheet for recording a sales history, and winding it into a roll by a winding means after cutting. Configured to be stored by. This allows receipt printing and journal printing with a single printing device.
[0009]
Here, the printing means may be any of a dot impact printing system, a thermal transfer printing system, an ink jet printing system, or a laser printing system.
[0010]
The separator means includes a blade disposed on a travel path of the roll sheet, and the roll sheet is configured to be separated left and right as the vehicle travels, and further the roll sheet travels. A circular cutter attached coaxially to the roll / sheet conveyance shaft in the separator means for the purpose.
[0011]
With the above configuration, the cash register according to the present invention is composed of one printing device, one roll sheet, and a roll sheet storage portion, and a separate printing mechanism and roll printing unit for receipt printing and journal printing. There is no need to provide a sheet conveying mechanism. As a result, the present invention has realized a significant reduction in manufacturing cost by reducing the number of parts and a miniaturization of the cash register.
[0012]
Furthermore, the present invention is characterized in that a separation device is provided for separating one printed sheet so as to be separated into a receipt and a journal in the transport direction. Since one sheet is separated, there is no difference in the paper replenishment timing for the receipt and the journal, and the paper for the receipt and the journal can be replenished by one replenishment. Accordingly, it is possible to realize a cash register machine in which the number of paper replenishment is reduced by approximately half, which is consistent with the improvement of customer service and the paper cost is reduced.

【Example】
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
[0014]
As described above, the cash register according to the present invention performs receipt printing on one side of the wide roll sheet 1 and journal printing on the other side by one printing device, and the separator means 3 after printing performs this. Are separated into left and right, one is issued to the customer as a receipt, and the other is stored in the apparatus as a journal.
[0015]
In the cash register according to the present invention, a dot impact printing system, a thermal transfer printing system, and an ink jet printing system can be freely selected as a built-in printing apparatus. However, the printing apparatus according to these systems is limited. It is not something.
[0016]
FIG. 1 is a perspective view of a portion relating to printing in a cash register according to the present invention.
[0017]
The roll sheet 1 accommodated in the roll sheet storage unit is conveyed along the sheet travel path and reaches the printing apparatus 2. The roll / sheet travel path is provided with conveying roller means for conveying the roll / sheet 1, a drive mechanism, and the like (not shown).
[0018]
In this embodiment, receipt printing is performed on the left side and journal printing is performed on the right side. In the receipt printing column, the store name or logo, the date and time of issue, the name of the product or service that is the sales details of the product or service, the unit price and quantity, the amount received, the change, the amount of consumption tax, etc. are printed. In the journal printing column,
Usually, only the date and time and the sales details of the product or service are printed. Therefore, the print information in the journal print field is usually less than the receipt print field.
[0019]
These printings in the printing apparatus 2 are performed in series. That is, when the printing apparatus 2 is a line thermal type thermal transfer, the receipt column and the journal column are simultaneously printed. In the case of the dot impact method or the ink jet method, the receipt column and the journal column of the roll sheet 1 are printed by printing while the print head 2a is driven to move left and right. In either case, each time a line is printed, the roll / sheet conveying means feeds the sheet for one line.
[0020]
The printing apparatus 2 includes a print head 2a (in the figure, a thermal transfer type thermal head 2a) and a platen 2b that supports the roll sheet 1 and is disposed at a position opposed to the roll sheet 1.
[0021]
Usually, a predetermined message (retail store logo, greeting, etc.) can be stamp printed on the top of the receipt sheet issued to the customer. For this purpose, an electro stamp 10 is installed between the roll sheet storage unit and the printing apparatus 2. The position of the electro stamp 10 may be placed at another position on the roll sheet traveling path.
[0022]
The wide roll sheet 1 on which the receipt printing and the journal printing are performed is further transported and passes through the separator means 3 disposed on the transport path. Here, the roll sheet 1 is separated left and right in parallel with the running direction. In this embodiment, the left side is a receipt and the right side is a journal.
[0023]
FIG. 2 shows an example of the separator means 3. The separator means 3 includes a roll / sheet conveyance shaft 7, a rubber roller 8, and a blade 9. First, when the printed roll sheet 1 passes through the installation position of the separator means 3 by the rotation of the roll / sheet conveyance shaft 7 and the journal / sheet take-up spool 11, the blade 9 causes the blade 9 to move left and right in parallel in the running direction. Separated. In order to assist the separation of the blade 9, a roll / sheet guide 4 can be installed against the separator 3. The roll sheet guide 4 facilitates separate cutting of the roll sheet 1 by pressing the roll sheet 1 against the blade 9 from the back side.
[0024]
A separate printing area is defined in advance for the receipt and the journal sheet at the time of separation. FIG. 3 is a view showing a state in which the printed roll sheet 1 is separated into a receipt part and a journal part.
[0025]
The blade 9 is formed by thinly molding a material such as metal or ceramics in order to smoothly cut the roll sheet 1. The shape is a rotating circular blade in this embodiment, but it may be a fixed rectangular or triangular blade.
[0026]
When the separator means 3 cuts the roll sheet 1 left and right, paper dust is generated. If this is left unattended, it will adversely affect the detection operation of a light detector or the like placed inside the cash register, causing trouble for the cash register. For this reason, it is preferable to install the paper dust collecting cover 5 on the roll / sheet guide 4. The paper dust collecting cover 5 is periodically cleaned when the roll sheet 1 is replenished.
[0027]
FIG. 4 shows a state in which the roll sheet 1 printed as described above is separated into a receipt part and a journal part after printing.
[0028]
One of the sheets separated by the separator means 3 is cut by a receipt cutting means 6 having a cutter assembly 6a and a cutter receiver 6b and discharged from a receipt discharge port 12. The other is wound as a journal sheet on a journal sheet winding spool 11.
FIG. 5 is a diagram showing an example of a control block for controlling the cash registering machine configured as described above.
[0029]
A central processing unit (hereinafter referred to as “CPU”) 13 that operates based on a program is connected to a ROM 14 that records programs and constant data, and a RAM 15 that temporarily records variable data. Further, a printer controller 18 is connected to the CPU 13 via the interface 16. The printer controller 18 includes various detection devices constituting the printing device 2, a print head controller 17 that controls the print head 2 a, an electro stamp 10, a roll / sheet conveyance roller 19 that conveys the roll sheet 1, The journal / sheet take-up spool driving means 20, the roll / sheet conveying shaft driving means 21, the receipt cutting means 6 and the like are connected to control these operations.
[0030]
The CPU 13 has an input device 22 for inputting necessary information through a numeric keypad, a barcode scanner, or the like via the interface 16, and a display device for displaying product items and their prices based on such input information. 23 is connected. In the case of product code input by a barcode scanner, the CPU 13 accesses a price reference file (PLU file) stored in an external in-store processor or the like, and stores the product name and the price associated with the product code on the premises. Reading is performed via the communication line, the read data is displayed on the display device 23, and is printed on the roll sheet 1 by the printing device 2. In printing, receipt information is printed on one side of the roll sheet 1 and journal information is printed on the other side based on a predetermined format.
[0031]
The journal sheet portion corresponding to the line line on which the receipt electro stamp 10 is stamped is blank. In the case of using a dot impact type printing apparatus, the print head 2a may not be sent to the blank portion by storing the feed range of the print head 2a in the ROM 14 in advance. Printing time can be shortened by such control.
[0032]
The roll sheet 1 printed in this way is separated into a receipt and a journal sheet by the separator means 3. The separated roll sheet 1 is cut by the receipt cutting means 6 and discharged from the receipt discharge port 12 as a receipt. The other separated roll sheet 1 is wound around a journal sheet take-up spool 11 as a journal sheet. The journal sheet taken up on the journal sheet take-up spool 11 may be extracted when the roll sheet 1 is replenished.
[0033]
Although the embodiment of the present invention has been described above, the present invention can be variously modified in addition to the above-described embodiment. For example, the printing device 2 may be selected according to the mode of use, purpose, and the like. The arrangement of the printing device, the storage position of the roll sheet 1 and the winding position of the journal sheet are determined according to the size of the cash register and the various devices incorporated therein.
[0034]
【The invention's effect】
As described above, in the cash register according to the present invention, receipt printing and journal printing are performed on one roll sheet stored in one roll sheet storage unit by using one printing apparatus. As a result, the device has been dramatically reduced in size and cost.
[0035]
Also, since one roll sheet is separated after printing by one printing device, it is not necessary to replenish the receipt and journal sheet separately, and it is possible to refill the receipt sheet by replenishing one type of roll sheet at a time. Journal sheets will be replenished. As a result, the number of roll sheet replenishment has been halved, improving customer service and reducing roll sheet maintenance costs.
