The support rod 33 is spanned between the pair of guide walls 31b and 31c on the support surface side, ie, the upper side, of the plate portion 31a. Both ends of the support rod 33 are inserted into the support hole 31h and supported by the guide walls 31b and 31c. The support rod 33 is disposed inside the folded portion of the main body portion 111 of the bag bundle 100A, and the main body portion 111 of the bag 100 is wrapped around the rear outer surface of the support rod 33 and folded. That is, the support rod 33 has a function of aligning the bags 100 by defining the folding line of the bags 100 in the first direction and guiding the pulling direction of the bags 100 in a direction perpendicular to the support rod 33 .

A second damper portion is provided on the outer periphery of the support rod 33 to bias the bag 100 against the support rod 33 . The second damper section includes a presser piece disposed on the outer surface of the bent portion of the bag 100A, and a biasing member such as a spring that biases the presser piece toward the support rod 33. The second damper section suppresses disturbance of the bags 100 by pressing the bag bundle 100A against the support rod 33.

The engaging portion 34 includes a bracket 41 fixed to the sub-tray 32, a load sensor 42 fixed to one side of the bracket 41, and a hook 43 provided on one side of the load sensor 42. The engaging portion 34 is provided on the opening/closing plate 32a at a central position in the first direction.

The bracket 41 is formed by bending a sheet metal into an L-shape, for example, and integrally includes a first fixing piece 41a and a second fixing piece 41b that form an angle of 90 degrees with each other. The first fixing piece 41a is fixed to the surface of the opening/closing plate 32a along the first direction and the fourth direction. The second fixing piece 41b is arranged, for example, along a plane perpendicular to the first fixing piece 41a when the opening/closing plate 32a is in the closed state, and has an attachment hole penetrating in the fourth direction. The load sensor 42 is fixed to the second fixed piece 41b by being fastened to a mounting hole whose axial direction is along the fourth direction with a fastening member such as a tap screw 42a or a nut 42b.

The load sensor 42 is a tensile type load cell that detects tensile force using a strain gauge. The load sensor 42 has one side in the fourth direction connected to the bracket 41 and the other side connected to the hook 43 by a fastening member such as a tap screw 42c. The load sensor 42 is connected between the bracket 41 and the hook 43 and detects the tensile force acting in the direction in which the hook 43 moves away from the bracket 41. Further, the load sensor 42 is configured to be able to communicate with a control unit 70 provided in the checkout device 12 as a host computer, and transmits detection information to the control unit 70.

The hook 43 has a J-shape that includes a linearly extending shaft portion 43a and a hook portion 43b whose distal end side of the shaft portion 43a curves upward and further curves forward. The shaft portion 43a of the hook 43 extends along the surface direction of the plate portion 31a and the second plate and along a fourth direction which is a pulling direction orthogonal to the width direction.

In the bag holding device 11 configured as described above, the holding tray 30 is inserted forward from the tray opening 26a at the rear of the housing 20 along the tray path extending in the fourth direction downward from the front. It is positioned in contact with the rear surface of the front and rear side walls of the housing 20 and set in the housing 20. On the other hand, when the rear end portion of the holding tray 30 is pulled rearward from the rear tray opening 26a, the holding tray 30 is removed from the housing 20.

When the holding tray 30 is removed from the housing 20, the opening/closing plate 32a is rotated upward to open the plate portion 31a. In this open state, the main body portion 111 of the bag bundle 100A is placed on the plate portion 31a, the opening/closing plate 32a is closed, and the main body portion 111 of the bag 100 is wound around the support rod 33 so that the handle 112 is placed forward. The bag bundle 100A is placed on the holding tray 30 by folding the bag and placing the handle 112 on the opening/closing plate 32a. Furthermore, the bag bundle 100A is held on the holding tray 30 by hooking the hole 113a of the cutting part 113 with the hook 43. At this time, the bottom of the bag 100 is led out from the front tray opening 23a, and the folded part of the bag 100 is exposed to the outside from the rear tray opening 26a.

In such a bag holding device 11, when the user pulls out a bag from the rear tray opening 26a, when the bag 100 disposed on the outermost periphery of the support rod 33 is pulled in the pulling direction, the load sensor 42 detects the pulling force. and transmits it to the control section 70.

Further, when the user pulls out a bag from the front tray opening 23a, when the bag 100 disposed on the innermost circumference of the support rod 33 is pulled forward, the load sensor 42 detects the pulling force, and the control unit Send to 70. At this time, as shown by the arrow Fα in FIG. 4, the pulling angle may be oriented in various directions depending on the direction of the user's fingers. However, since the bag 100 is bent along the outer periphery of the support rod 33 extending in the first direction, the direction of the load applied to the hook 43 via the support rod 33 is as shown by arrows Fβ and F in FIG. It is converted toward a fourth direction perpendicular to the support rod 33. Therefore, the direction of the tensile force applied to the load sensor 42 is aligned in the fourth direction.

That is, when pulling out from either tray opening 23a or 26a, the direction of the load applied to the load sensor 42 is aligned in the fourth direction, which is orthogonal to the support rod 33 and is a predetermined guide direction guided by the plate portion 31a. .

Performs the withdrawal process to be transported to the ejection port or coin ejection port.

The control unit 70 includes a processor 71, a main memory 72, an auxiliary storage device 73, a communication interface 74, and a system transmission path 75.

The processor 71 corresponds to the central part of the control section. The processor 71 controls each part to implement various functions of the checkout device 12 according to an operating system or an application program. The processor 71 is, for example, a CPU (Central Processing Unit).

The main memory 72 corresponds to the main memory portion of the computer. Main memory 72 includes a nonvolatile memory area and a volatile memory area. Main memory 72 is a nonvolatile memory area that stores an operating system or application programs. The main memory 72 stores data necessary for the processor 71 to execute processing for controlling each unit in a volatile memory area. The above data may be stored in a non-volatile memory area. The main memory 72 uses a volatile memory area as a work area in which data is appropriately rewritten by the processor 71. The nonvolatile memory area is, for example, ROM (Read Only Memory). The volatile memory area is, for example, RAM (Random Access Memory).

The auxiliary storage device 73 corresponds to the auxiliary storage portion of the control section. For example, the auxiliary storage device 73 may be an EEPROM (Electric Erasable Programmable Read-Only Memory), an HDD (Hard Disc Drive), or an SSD (Solid State Drive). The auxiliary storage device 73 stores data used by the processor 71 in performing various processes, data created by processing by the processor 71, and the like.

The communication interface 74 performs data communication with the holding device 11 under the control of the processor 71 .
The system transmission path 75 includes an address bus, a data bus, a control signal line, and the like.

The control section 70 is connected to the operation display section 52, the reading section 53, the receipt processing section 54, and the money processing section 55, and controls the operation of each section. The control unit 70 drives the drive circuits of each unit, such as the monitor and the money processing unit 55, according to various programs based on data detected or input by various sensors, barcode scanners, card readers/writers, and touch panels. This controls the operation of each part.

In the control unit 70, data for bag management is stored in a storage unit such as a main memory 72 or an auxiliary storage device 73 as part of data necessary for product sales. The data for bag management is information such as the correspondence between the load and the number of sheets to be cut out, which is stored in advance, based on the relationship between the tensile load and the number of sheets to be cut out, for example. Here, FIG. 6 is a graph showing the relationship between the load related to the hook that supports the holding piece 113 of the bag bundle 100A and the number of bags to be cut when cutting the bags 100 from the bag bundle 100A. In FIG. 6, as shown in FIG. 8, the bag bundle 100A is hung by hooking the holding piece 113 on the hook member, and when the bag 100 is pulled downward while hanging downward without being bent, the hook member Indicates the load. As shown in FIG. 6, there is a correspondence between the number of bags pulled at one time and the load. FIG. 7 is a graph showing the relationship between the pulling angle and the load when the bag bundle 100A is suspended from the hook member as shown in FIG. 8 and the angle at which the bag 100 is pulled is changed. As shown in FIG. 7, the tensile load changes depending on the direction in which the bag 100 is pulled.

For example, the control unit 70 drives the money processing unit 55 at a predetermined timing based on data detected by various sensors, a barcode scanner, a card reader/writer, a touch panel, or input, and performs money deposit/withdrawal processing. Performs various processing such as accounting, judgment, deposit, change calculation, change supply, etc.

Further, the control unit 70 calculates the number of used bags 100 based on the detection result of the load sensor 42. For example, the processor 71 counts the peak number from the value and fluctuation of the load detected by the load sensor 42 and the bag management data stored in the storage unit, and calculates the number of sheets to be cut based on the peak value. Accordingly, the number of bags 100 used for one transaction process is calculated.

For example, the control unit 70 performs bag billing processing in which the calculated number of cut sheets is added to the total product price for each transaction. For example, when accounting for money, the bag price corresponding to the number of 100 bags cut out is added to the total product price. Further, as one of the bag management processes, the control unit 70 displays information regarding the number of bags 100 used at the time of each transaction, for example, on the operation display unit 52 or prints it on the receipt.

Further, the control unit 70 manages the remaining amount of bags based on the detection result of the load sensor 42. For example, the processor 71 calculates the remaining number of bags based on the detection result of the load sensor 42 by subtracting the counted cumulative number of cut sheets from the set number inputted when the bag bundle 100A was set, for example.

The control unit 70 performs a notification process to inform the user of the remaining amount of the bag, as an example of managing the remaining amount of the bag. For example, when the number of bags remaining falls below a certain value, the control unit 70 causes the operation display unit 52 to display notification information, such as a message or image, informing that the number of bags remaining is small as a notification process.

According to the checkout device 12 according to the present embodiment, the bags 100 can be stored and protected within the housing 20, and a portion of the bags 100 can be exposed from the tray openings 23a and 26a, thereby preventing the bags 100 from being scattered. , it is possible to achieve both ease of removal. Further, since the main body portion 111 of the bag 100 bent by the support rod 33 is held by the tray portion 30 tilted forward and downward, an appropriate tension is maintained by the weight of the bag 100, and the posture of the bag is stabilized. Therefore, handling of the bag 100 becomes easy. Moreover, since the number of bags 100 can be calculated from the load applied to the hook 43, it is possible to simply arrange the load sensor 42 between the hook 43 that supports the holding piece 113 of the bag 100 and the bracket 41 that supports the hook 43. With this configuration, it is possible to manage the number of sheets.

Furthermore, in the bag holding device 11, by placing the bag 100 on the plate portion 31a and aligning the posture of the bag 100, the pulling direction can be guided along the surface direction of the plate portion 31a. Furthermore, by having a structure in which the support rod 33 extending in the first direction is wrapped around and folded, the direction of the pull applied to the load sensor 42 can be aligned in the fourth direction orthogonal to the support rod 33. Therefore, even if the pulling angle varies, the direction of the load on the load sensor 42 can be stabilized, and the accuracy of calculating whether or not to cut out and the number of sheets to be cut can be improved.

It should be noted that the present invention is not limited to the above-described embodiments as they are, but can be implemented by modifying the constituent elements within the scope of the invention at the implementation stage.

For example, in the above embodiment, an example of displaying a message on a monitor is shown as an example of notification processing, but the invention is not limited to this. For example, a configuration that includes lighting and speakers and performs notification processing with light or sound You can also use it as
