[0021] 1. Structure of information terminal device

[0022] Figure 1 The information terminal device 100 shown is, for example, a so-called kiosk terminal. The kiosk terminal is used for providing service information, various payment, acceptance and other procedures.

[0023] The information terminal device 100 incorporates the roll paper printer 1 and the paper guide 10 . The information terminal device 100 also includes a touch panel 103 , a reader 104 , and an issue port 102 in a housing 101 .

[0024] It should be noted that the roll paper printer 1 and the paper guide 10 will be described in detail later.

[0025] The touch panel 103 includes a display device such as a liquid crystal display and an input device for detecting an operation on a displayed screen. The customer operates the screen based on the displayed menu via the touch panel 103 .

[0026] The information terminal device 100 includes a control unit (not shown) including a processor and a memory. The memory stores a program. The processor reads the program from the memory and executes it. The control unit executes various processes based on the operation detected by the touch panel 103 .

[0027] The reader 104 can read information such as an IC or a two-dimensional code carried on a customer's card, a portable terminal, or the like.

[0028] For example, in a hospital or the like, the information terminal device 100 acquires information including customer identification information from a customer's card or portable terminal via the reader 104 , prints a receipt via the roll paper printer 1 , and discharges the receipt from the issuing port 102 via the paper guide 10 .

[0029] In a small store, the information terminal device 100 obtains information including payment information from a customer's card through the reader 104 and performs payment, and prints a receipt through the roll paper printer 1, which is ejected from the issuing port 102 through the paper guide 10. In this case, the information terminal device 100 may also be provided with a so-called automatic change machine having the function of depositing and dispensing cash.

[0030] When the housing 101 of the information terminal device 100 is opened, the roll paper printer 1 and the paper guide 10 are exposed, allowing a service person to perform maintenance or the like.

[0031] 2. Structure of roll paper printer

[0032] The roll paper printer 1 is a roll paper printer for assembly in the information terminal device 100. Figure 2 As shown, the roll paper printer 1 includes a printer case 3 that can accommodate a roll paper R, and a cover 2 that can open and close the printer case 3. The cover 2 can rotate around a hinge 2a of the printer case 3. After opening the housing 101 of the information terminal device 100, the service personnel can open the cover 2 of the roll paper printer 1 and store the roll paper R in the printer case 3.

[0033] The cover 2 is equipped with a platen roller 30 , a first roll paper guide 4 , and a first blade 41 constituting a cutter 40 . On the other hand, the printer case 3 is equipped with a head 20 , a second roll paper guide 5 , and a second blade 42 constituting a cutter 40 .

[0034] When the cover 2 is closed, the platen roller 30 and the head 20 and the first blade 41 and the second blade 42 of the cutter 40 are located at positions facing each other. The cutter 40 is located downstream in the conveying direction T relative to the platen roller 30 and the head 20.

[0035] When the cover 2 is closed, a rectangular paper discharge port 6 is formed between the cover 2 and the printer case 3. The roll paper R is rotatably supported by the first roll paper guide 4 of the cover 2 and the second roll paper guide 5 of the printer case 3.

[0036] The platen roller 30 is formed in a cylindrical shape from a flexible material such as rubber or other resin.

[0037] The platen roller 30 and the head 20 sandwich the first paper P1 at a nip position 30a. The platen roller 30 transports the first paper P1 by a friction transport method, i.e., a friction feed method. The platen roller 30 is a so-called transport roller that transports the first paper P1. The platen roller 30 rotates in the clockwise direction, extracts the first paper P1 from the roll paper R accommodated in the printer case 3, and transports it in the transport direction T. At this time, the roll paper R also rotates clockwise.

[0038] Note that the paper P is generally referred to as paper that is wound around the paper roll R, pulled out from the paper roll R, printed, and cut, including the first paper P1 and the second paper P2 described later.

[0039] The platen roller 30 can convey the paper P to the issuing port 102 of the information terminal device 100 via the paper guide 10 .

[0040] The head 20 is, for example, a line thermal head and has a pressing mechanism (not shown) for pressing against the platen roller 30. The first paper P1 is nipped by the platen roller 30 and the head 20 at a nip position 30a with a predetermined pressure by the pressing mechanism.

[0041] The paper P is, for example, a long thermal paper. The first surface P1a of the first paper P1 is a conveying surface conveyed by the platen roller 30. The second surface P1b of the first paper P1, which is the opposite surface to the first surface P1a, is a printing surface coated with a developer.

[0042] The first surface P1a of the first paper P1 contacts the platen roller 30 to be conveyed, and the second surface P1b contacts the head 20 at the nip position 30a to be colored by heat generated by the head 20 for printing. The paper roll R is wound with the outer side serving as the printing surface.

[0043] The roll paper printer 1 includes a printer control unit (not shown). The printer control unit includes a processor that centrally controls the various components of the roll paper printer 1 , a memory, and the like. The memory stores programs. The processor reads the programs from the memory and executes various controls.

[0044] The printer control unit can control the paper P to be unwound from the paper roll by the platen roller 30 and conveyed, to be printed by the head 20 , to be cut by the cutter 40 , and so on.

[0045] 3. Structure of the Paper Guide of the First Embodiment

[0046] Reference Figure 2 , Figure 3 The paper guide 10 of the first embodiment will be described. Figure 2 As shown, the information terminal device 100 has a paper guide 10 for guiding the first paper P1 mounted on a housing 101. The paper guide 10 has a first opening 11 for inserting the first paper P1 from the rear and a second opening 12 for feeding the first paper P1 forward.

[0047] The paper guide 10 includes a first guide 15 capable of guiding the first paper P1 from below, a roller 17 capable of guiding the first paper P1 from above, a second guide 16 covering the roller 17 from above, and a mounting plate 18 for mounting the paper guide 10 on the housing 101 .

[0048] The mounting member 18a is a double-sided tape, adhesive, etc., and fixes the mounting plate 18 of the paper guide 10 to the inside of the housing 101. It should be noted that the mounting member 18a can be a screw, etc., and can detachably mount the mounting plate 18 to the inside of the housing 101.

[0049] As a result, the second opening 12 of the paper guide 10 is in a position communicating with the issuing port 102 formed as a rectangular hole in the housing 101, and the first paper P1 can be fed to the issuing port 102. In addition, when the housing 101 is closed, the first opening 11 of the paper guide 10 is in a position communicating with the paper discharge port 6 of the roll paper printer 1, and the first paper P1 discharged from the paper discharge port 6 can be inserted.

[0050] The first paper P1 conveyed in the conveying direction T by the platen roller 30 of the roll paper printer 1 and discharged from the paper discharge port 6 enters the first opening 11 as the entrance of the paper guide 10. At this time, the first paper P1 can be guided from above to the inclined surface 16b of the second guide 16 inclined forward and downward toward the first guide 15, and can smoothly enter the first opening 11.

[0051] In the paper guide 10 , the roller 17 is located opposite to the first guide 15 . The first surface P1a of the first paper P1 entering the first opening 11 is guided from below by the first guide 15 , and the second surface P1b is guided from above by the roller 17 .

[0052] The first opening 11 of the paper guide 10 is defined above by an end 16 a which is a front lower front end of the inclined surface 16 b of the second guide 16 , and is defined below by the first guide 15 .

[0053] The second opening 12, which is the exit of the paper guide 10 for the first paper P1, is communicated with the first opening 11 in the conveying direction T. The first paper P1 is conveyed in the conveying direction T by the platen roller 30 of the roll paper printer 1, enters the first opening 11 of the paper guide 10, and is delivered from the second opening 12. At this time, the first paper P1 is pressed from above by the roller 17 with a pressing force W as described later.

[0054] The up-down direction of the second opening 12 is defined by the roller 17 and the first guide 15 .

[0055] Alternatively, the left and right directions of the first opening 11 and the second opening 12 may be defined by opposing plate-like portions rising upward from the left and right ends of the first guide 15 or plate-like portions descending downward from the left and right ends of the second guide 16. Thus, the first paper P1 can be guided from left and right.

[0056] The portion of the first guide 15 that contacts the first paper P1 is formed as a flat surface in the front-rear and left-right directions. The first guide 15 is made of a resin such as polyethylene, for example.

[0057] In the first guide 15 , at least a portion that contacts the first paper P1 is covered with a sheet 15 a made of, for example, ultra high molecular weight polyethylene (Ultra High Molecular Weight Polyethylene).

[0058] Ultra-high molecular weight polyethylene is obtained by increasing the molecular weight of ordinary polyethylene to 1 million to 7 million. Compared with polyethylene, the sheet 15a of ultra-high molecular weight polyethylene can reduce the friction between the sheet 15a and the object in contact. In addition, compared with polyethylene, the sheet 15a of ultra-high molecular weight polyethylene can suppress the static electricity generated between the sheet 15a and the object in contact, and can further reduce the friction. The sheet 15a containing ultra-high molecular weight polyethylene is also called a so-called low friction sheet. As described later, the friction coefficient of the sheet 15a is smaller than the friction coefficient of the paper P. Therefore, the friction between the sheet 15a and the paper P is smaller than the friction between the papers P.

[0059] The first guide 15 can guide the first surface P1a of the first paper P1. The roller 17 can guide the second surface P1b of the first paper P1, which is the opposite surface to the first surface P1a, at a position facing the first guide 15.

[0060] As will be described later, the first paper P1 can be guided and held by the first guide 15 and the roller 17 .

[0061] The second guide 16 is arranged above the roller 17, that is, on the side opposite to the first guide 15. It should be noted that a plurality of arc-shaped ribs along the circumference of the roller 17 may be provided on the roller 17 side above the second guide 16 to press the roller 17 that bounces upward. This is because, as described later, the upper side of the groove-shaped support portion 14 is open, and therefore, the roller 17 may bounce upward together with the shaft 17a due to the movement of the first paper P1.

[0062] The roller 17 is formed in a cylindrical shape by resin such as plastic or rubber, and can rotate around a shaft 17 a by contacting the first paper P1 entering from the first opening 11 .

[0063] It should be noted that the roller 17 may be composed of a plurality of rollers, or may be partially provided with annular ribs on the circumference. The roller 17 having such a structure can contact the first paper P1 with good balance in the paper width direction.

[0064] The support portion 14 is in an arc shape on one side facing downward, that is, facing the plane of the first guide 15, and has a groove extending upward, that is, in a direction away from the plane of the first guide 15. The upper side of the groove-shaped support portion 14 is open. The support portion 14 of such a shape supports the shaft 17a so that it can move. In addition, the support portion 14 can contact the shaft 17a and allow the roller 17 pressed by the first paper P1 and the shaft 17a to move smoothly.

[0065] The support portion 14 is provided at the left and right positions of the shaft 17a, and can support the shaft 17a. It should be noted that the support portion 14 may also be provided on the first guide 15 or the second guide 16. The left and right support portions 14 may also be provided on the plate-like portions that stand upward from the left and right ends of the first guide 15 in a manner opposite to each other. Alternatively, the left and right support portions 14 may also be provided on the plate-like portions that descend downward from the left and right ends of the second guide 16 in a manner opposite to each other.

[0066] The support portion 14 may be formed integrally with the first guide 15 or the second guide 16 by resin.

[0067] When the support portion 14 is provided on the first guide 15 , the support portion 14 has a groove shape, and therefore the roller 17 can be thrown in from the open upper side of the support portion 14 and assembled easily.

[0068] On the other hand, when the support portion 14 is provided in the second guide 16, the support portion 14 and the second guide 16 can be handled as a unit in which the roller 17 is assembled. For example, the support portion 14 and the second guide 16 can be easily assembled and replaced with respect to the first guide 15 as a unit in which the roller 17 is assembled.

[0069] 4. Structure of Paper Guide of Second Embodiment

[0070] Reference Figure 4 , a paper guide 10a of the second embodiment will be described. The paper guide 10a will be described mainly with respect to the points that are different from the paper guide 10 of the first embodiment, and descriptions of the same structures as the paper guide 10 will be omitted. Figure 4 In the drawings, the same components as those of the paper guide 10 of the first embodiment are shown using the same reference numerals.

[0071] The support portion 14a of the paper guide 10a of the second embodiment is a long hole in an elliptical shape that is long in the vertical direction. The support portion 14a of such a shape can support the shaft 17a so that it can move. In addition, the support portion 14a can contact the shaft 17a and allow the roller 17 pressed by the first paper P1 and the shaft 17a to move smoothly.

[0072] The support portion 14a is provided at the left and right positions of the shaft 17a, and can support the shaft 17a. It should be noted that the support portion 14a may also be provided on the first guide 15. The left and right support portions 14a may also be configured as plate-like portions that stand upward from the left and right ends of the first guide 15 in a mutually opposed manner. In addition, the support portion 14a may also be configured to be integrally molded with the first guide 15 by resin.

[0073] When the support portion 14a is provided on the first guide 15, the support portion 14a can be handled as a unit by assembling the roller 17 to the support portion 14a. For example, the support portion 14a and the first guide 15 can be easily assembled and replaced as a unit to which the roller 17 is assembled.

[0074] As described above, the first paper P1 is fed from the first opening 11 of the paper guide 10a through the second opening 12 in the feeding direction T by the platen roller 30 of the roll paper printer 1 and discharged from the issuing port 102. At this time, the first paper P1 fed from the issuing port 102 may be pressed or caught by the customer's hand.

[0075] In this case, the first paper P1 in the paper guide 10a cannot be fed out from the second opening 12, while the first paper P1 that is still being fed enters from the first opening 11. As a result, there is a risk that the first paper P1 will be clogged in the paper guide 10a.

[0076] The paper guide 10a has a structure in which a portion of the second guide 16 covering the roller 17 from above is removed from the paper guide 10. As a result, the third opening 13 is formed above the paper guide 10.

[0077] The third opening 13 communicates with the upper rear portion of the first opening 11 . If the first paper P1 cannot be delivered from the second opening 12 due to the customer pressing the first paper P1 at the issuing port 102 , the first paper P1 can be delivered in a direction different from the second opening 12 through the third opening 13 .

[0078] That is, the first paper P1 newly introduced from the first opening 11 can be fed out from the third opening 13 in an upward direction different from the conveyance direction T. The third opening 13 can discharge the first paper P1 that cannot be fed out from the second opening 12 .

[0079] Note that the paper guide 10a has the inclined surface 16b similarly to the paper guide 10. Also, similarly to the paper guide 10, the paper guide 10a defines the upper side of the first opening 11 by the end 16a which is the front lower front end of the inclined surface 16b.

[0080] In this case, the inclined surface 16b of the paper guide 10a is configured to extend from the left and right ends of the first guide 15. In addition, the inclined surface 16b may be configured to be integrally molded with the first guide 15 by resin.

[0081] 5. Operation of the Main Parts of the Paper Guide 10

[0082] Next, refer to Figures 5 to 10, the operation of the main part of the paper guide 10 will be described. It should be noted that, although the following description is made by taking the example of the groove-shaped support portion 14 of the paper guide 10 of the first embodiment, the same is true for the long hole-shaped support portion 14a of the paper guide 10a of the second embodiment.

[0083] like Figure 5 As shown, the first paper P1 discharged from the paper discharge port 6 (not shown) of the roll paper printer 1 is transported in the transport direction T1 toward between the roller 17 and the first guide 15 .

[0084] It should be noted that the first paper P1 is in a state before being cut by the cutter 40 (not shown), and is transported in the transport direction T1 by the platen roller 30 (not shown) of the roll paper printer 1 located behind the roller 17 and the first guide 15. Then, the first paper P1 is discharged from the issuing port 102 (not shown) of the information terminal device 100.

[0085] The roller 17 contacts the first guide 15 via the sheet 15a, and presses the first guide 15 with a pressing force W. In this case, the pressing force W is generated by the weight of the roller 17 including the shaft 17a. It should be noted that the pressing force W may be generated via the roller 17 by a spring, rubber, etc. not shown.

[0086] The pressing force W is preferably in the range of 5 gf to 30 gf, and more preferably 7 gf. For example, the outer diameter of the roller 17 is 7 mm, and the outer diameter of the shaft 17 a is 3 mm.

[0087] When the roller 17 contacts the first guide 15 via the sheet 15a, the shaft 17a of the roller 17 can have gaps of distance L2 in front and behind and distance L1 in the bottom of the support 14. For example, the distance L2 is preferably 0.5 mm, and the distance L1 is preferably 1 mm.

[0088] The shaft 17a can move a distance L2 before and after the support portion 14. Since the shaft 17a is away from the support portion 14 by a distance L1, it can float from the support portion 14 together with the roller 17, and the roller 17 can reliably press the first paper P1 with a pressing force W as described later.

[0089] It should be noted that when the roller 17 contacts the first guide member 15 via the sheet 15a, the shaft 17a can be separated from the support portion 14 by the distance L1 and the distance L2. Figure 5 As shown, it is also possible not to contact the support portion 14 .

[0090] The support portion 14 is configured as a so-called U-shaped groove. A portion of the support portion 14 located at the lower side facing the plane of the first guide 15 is in an arc shape in accordance with the shape of the shaft 17a.

[0091] The support portion 14 has a front upper slope extending forward and upward from the arc-shaped portion below, and a rear upper slope extending backward and upward. The front upper slope is referred to as a first slope, and the rear upper slope is referred to as a second slope. The two slopes extend obliquely upward in a manner separated from each other before and after the arc-shaped portion of the support portion 14. That is, the two slopes are slightly inclined and face each other, and extend upward from the arc-shaped portion.

[0092] It should be noted that, in the U-shape, the surface extending upward may not be composed of an inclined surface, but may be composed of a vertical surface extending vertically upward, or may be composed of a combination of the inclined surface and the vertical surface.

[0093] It should be noted that the shape of the support portion 14 a of the second embodiment is a long hole, but the above-mentioned structure of the support portion 14 of the first embodiment is the same.

[0094] With the support portion 14 having such a structure, the shaft 17a of the roller 17 can move freely within the range of the support portion 14. In addition, if the shaft 17a contacts the support portion 14, it can move smoothly along any of the two inclined surfaces. The roller 17 can also move similarly together with the shaft 17a.

[0095] If you will Figure 5 The first paper P1 shown in FIG. 1 is further transported along the transport direction T1. Figure 6 As shown, the leading end of the first paper P1 enters between the roller 17 and the first guide 15 .

[0096] The roller 17 contacts the front end of the first paper P1 and is pressed, and moves forward and is lifted upward. In addition, the roller 17 can press the first paper P1 with a pressing force W while rotating in the counterclockwise direction. At this time, the shaft 17a of the roller 17 also moves forward and upward. The shaft 17a can smoothly move forward and upward along the front upper slope of the support portion 14 while contacting the front upper slope. In addition, the shaft 17a also rotates counterclockwise together with the roller 17.

[0097] In this way, the support portion 14 movably supports the shaft 17 a of the roller 17 , so that the conveyed first paper P1 presses the roller 17 , and the shaft 17 a can smoothly move together with the roller 17 .

[0098] The roller 17 can be pressed by the front end of the first paper P1 and move in a floating manner while rotating. Therefore, the front end of the first paper P1 can easily enter under the roller 17. That is, the load when the front end of the first paper P1 enters between the first guide 15 and the roller 17 is reduced by the support part 14 having such a structure, and the front end of the first paper P1 can easily enter.

[0099] Specifically, if Figure 5 As shown, when the roller 17 contacts the first guide 15 via the sheet 15a, the shaft 17a of the roller 17 can be located not in contact with the support 14. At this time, as described above, a gap is generated such that the shaft 17a does not contact the support 14 due to the distances L1 and L2.

[0100] like Figure 6 As shown, the first paper P1 enters between the roller 17 and the first guide 15, and the roller 17 contacts the first paper P1. At this time, the roller 17 can move forward and backward and up and down together with the shaft 17a through these gaps. Therefore, the first paper P1 can easily sneak under the roller 17, and the roller 17 can press the first paper P1 with the pressing force W generated by its own weight.

[0101] If you will Figure 6 The first paper P1 shown is further transported in the transport direction T1. Figure 7 As shown, the first paper P1 is pressed by the roller 17 from above with a pressing force W, and is guided forward by the roller 17 and the first guide 15. Next, the first paper P1 is cut into a predetermined length by the cutter 40 located behind the roller 17 and the first guide 15. For example, when the first paper P1 is issued as a receipt, the predetermined length is about 70 mm. Depending on the printed content such as the number of purchased goods, the receipt may be shorter than 70 mm or longer than 70 mm.

[0102] Hereinafter, the first paper P1 before being cut by the cutter 40 is simply referred to as the first paper P1 , and the first paper P1 cut to form paper pieces is also referred to as the second paper P2 .

[0103] The roller 17 is pressed by the first paper P1 between the roller 17 and the first guide 15. Figure 5 The position shown in FIG. 1 is moved upward by the thickness of the first paper P1. At this time, the shaft 17a of the roller 17 is also relative to the Figure 5 The position shown is moved upward by the thickness of the first paper P1 in the support portion 14. The thickness of the first paper P1 is, for example, in the range of 50 μm to 90 μm.

[0104] It should be noted that in Figure 7 2 shows a case where the shaft 17 a is not in contact with the support portion 14 , but there may be a case where the shaft 17 a is in contact with the first inclined surface or the second inclined surface of the support portion 14 .

[0105] Here, the friction coefficient between the first surface P2a of the second paper P2 and the sheet 15a of the first guide 15 is set to the second friction coefficient μ2. When the second paper P2 moves in the conveying direction T1, a second friction force F2 based on the second friction coefficient μ2 is generated in the opposite direction of the conveying direction T1 between the first surface P2a of the second paper P2 and the sheet 15a.

[0106] The second friction force F2, the second friction coefficient μ2, and the pressing force W of the roller 17 are in the relationship of F2=μ2×W. That is, the second friction force F2 is a value obtained by multiplying the second friction coefficient μ2 by the pressing force W. The second friction coefficient μ2 is preferably in the range of 0.05 to 0.2, and more preferably 0.1.

[0107] The second paper P2 can be held by the roller 17 by pressing with a pressing force W while being sandwiched between the first guide 15 and the roller 17. Furthermore, a second friction force F2 is generated in the opposite direction to the conveying direction T1 in which the second paper P2 falls. As a result, the second paper P2 is prevented from falling from the first guide 15. That is, the second paper P2 is prevented from falling from the issuing port 102 of the information terminal device 100.

[0108] For example, the second paper P2 printed by the head 20 and cut by the cutter 40 and issued as a receipt can be held by the pressing force W of the roller 17 while placed on the first guide 15. The customer can easily take out the second paper P2 held as a receipt without falling from the first guide 15 from the issuing port 102.

[0109] Figure 8 The following figure shows a case where the next first paper P1 is conveyed in a state where the second paper P2 placed on the first guide 15 is not removed but remains.

[0110] The first paper P1 discharged from the paper discharge port 6 is conveyed in the conveying direction T1 by the platen roller 30 of the roll printer 1. The leading end of the first paper P1 overlaps the second paper P2 placed on the first guide 15 and enters between the roller 17 and the first guide 15.

[0111] The roller 17 contacts and presses the front end of the first paper P1, and then moves forward and lifts upward. The roller 17 can press the stacked first paper P1 and second paper P2 with a pressing force W while rotating counterclockwise.

[0112] At this time, the shaft 17a of the roller 17 also moves further to the upper front direction. The shaft 17a can smoothly move along the upper front slope with the roller 17 while contacting the upper front slope of the support portion 14. And the shaft 17a also rotates counterclockwise with the roller 17.

[0113] In this way, the support portion 14 supports the shaft 17a of the roller 17 so that it can move, and thus the first paper P1 that is overlapped on the second paper P2 and transported can make the shaft 17a move smoothly together with the roller 17. In other words, when the first paper P1 and the second paper P2 are overlapped, the support portion 14 can freely move the roller 17 together with the shaft 17a and support them.

[0114] The roller 17 can be pressed by the front end of the first paper P1 and move in a floating manner while rotating. Therefore, the front end of the first paper P1 overlaps on the second paper P2 and easily enters under the roller 17. That is, by the support part 14 of such a structure, the load when the front end of the first paper P1 overlaps on the second paper P2 and enters between the first guide 15 and the roller 17 is reduced, and it can easily enter.

[0115] like Fig. 9 As shown, when the next first paper P1 is transported in the transport direction T1 , it overlaps on the second paper P2 and moves forward while being sandwiched between the roller 17 and the first guide 15 .

[0116] The roller 17 is pressed by the first paper P1 and the second paper P2 and moves upward by the thickness of the first paper P1 and the second paper P2.

[0117] The first paper P1 and the second paper P2 are sandwiched between the roller 17 and the first guide 15, and are applied with a pressing force W from the roller 17. At this time, the first paper P1 transported in the transport direction T1 tries to press the second paper P2 in the moving direction T2.

[0118] The friction coefficient between the second surface P2 b of the second paper P2 and the first surface P1 a of the first paper P1 is referred to as a first friction coefficient μ1.

[0119] A first friction force F1 is generated between the second surface P2b of the second paper P2 and the first surface P1a of the first paper P1 being transported. The first friction force F1, the first friction coefficient μ1, and the pressing force W of the roller 17 are in a relationship of F1=μ1×W. That is, the first friction force F1 is a value obtained by multiplying the first friction coefficient μ1 by the pressing force W. It should be noted that the first friction coefficient μ1 is preferably in the range of 0.3 to 1.0.

[0120] On the other hand, as described above, the second friction force F2 having the second friction coefficient μ2 is generated in the direction opposite to the transport direction T1 between the sheet 15 a of the first guide 15 and the first surface P2 a of the moving second paper P2 .

[0121] Since the friction coefficient of the sheet 15a is smaller than that of the paper P, the relationship of second friction coefficient μ2<first friction coefficient μ1 is achieved. For example, the second friction coefficient μ2 in the range of 0.05 to 0.2 is smaller than the first friction coefficient μ1 in the range of 0.3 to 1.0.

[0122] Since μ2<μ1, (F2=μ2×W)<(F1=μ1×W), that is, F2<F1. Thus, the second friction force F2 is smaller than the first friction force F1 by the sheet 15a. The second paper P2 is in a state of being easy to slide on the sheet 15a of the first guide 15 below relative to the first paper P1 stacked on it.

[0123] In the second paper P2 , the second friction force F2 is applied to the first surface P2 a in the direction opposite to the transport direction T1 , and the first friction force F1 is applied to the second surface P2 b in the transport direction T1 .

[0124] Furthermore, since F2<F1, the first friction force F1 acting in the transport direction T1 on the second paper P2 is greater than the second friction force F2 acting in the opposite direction to the transport direction T1.

[0125] As a result, a force of (F1-F2)=(μ1-μ2)×W acts forward in the conveying direction T1 or the moving direction T2. ​​Therefore, the second paper P2 moves forward in the conveying direction T1 or the moving direction T2 due to the conveyed first paper P1.

[0126] That is, the platen roller 30 of the roll paper printer 1 can move so as to push out the second paper P2 cut by the cutter 40 by conveying the first paper P1 before being cut by the cutter 40 .

[0127] like Fig.10 As shown in FIG. 1 , if the first paper P1 is further transported along the transport direction T1, the second paper P2 is further pushed and moved. If the rear end of the second paper P2 is pushed by the first paper P1 and separates from the roller 17 and the first guide 15, the pressing force W of the roller 17 no longer acts on the second paper P2, and the second paper P2 falls from the first guide 15. That is, the second paper P2 falls from the issuing port 102 of the information terminal device 100.

[0128] For example, the customer may not remove the second paper P2 issued as a receipt and held on the first guide 15 from the issuing port 102. In this case, the second paper P2 remaining on the first guide 15 without being removed can be dropped from the issuing port 102 by the structure of the paper guide 10 as described above.

[0129] This can prevent the customer from mistakenly taking the second paper P2, which is the previously issued receipt, instead of taking the next first paper P1, which is the newly issued receipt.

[0130] It should be noted that the roller 17 is pressed by the first paper P1 located between the roller 17 and the first guide 15. Figure 5 The position shown is moved upward by the thickness of the first paper P1.

[0131] The information terminal device 100 according to the above embodiment includes: a roll paper printer 1 that pulls out a first paper P1 from a roll paper R and performs printing and cutting; a paper guide 10 that guides the first paper P1; and an outlet 102 that discharges the first paper P1. In addition, the paper guide 10 includes: a first guide 15 that guides a first surface P1a of the first paper P1; a roller 17 that guides a second surface P1b of the first paper P1 at a position opposite to the first guide 15, the second surface P1b being the opposite surface of the first surface P1a; and a support unit 14 that supports a shaft 17a of the roller 17 so that it can move.

[0132] According to the above-mentioned information terminal device 100, the first paper P1 and the cut second paper P2 can be guided and held by the first guide 15 and the roller 17. Furthermore, the support portion 14 supports the shaft 17a of the roller 17 so as to be movable, so that the first paper P1 can move the shaft 17a together with the roller 17 and can easily enter between the first guide 15 and the roller 17. In addition, when the second paper P2 remains on the first guide 15, the second paper P2 can be dropped from the issuing port 102 by the first paper P1.

[0133] As mentioned above, although embodiment is described in detail with reference to drawings, the specific structure is not limited to embodiment, unless it deviates from the main point of this invention, it is possible to change, replace, delete, etc.

[0134] The head 20 of the roll paper printer 1 is described as a thermal head, but the printing method is not limited. For example, the head 20 may be an inkjet head. In this case, the inkjet head cannot contact the platen roller 30 and clamp the first paper P1, so a driven roller that faces the platen roller 30 and clamps the first paper P1 can be mounted on the printer box 3. In this case, the first paper P1 may also be ordinary paper or the like.

[0135] In the above description, an example is described in which the cover 2 of the roll paper printer 1 is equipped with the platen roller 30 and the first blade 41 constituting the cutter 40, and the head 20 and the second blade 42 are mounted on the printer housing 3, but the cover 2 and the printer housing 3 may be mounted oppositely. In this case, the first paper P1 is wound around the roll paper R so that the outer side becomes the conveying surface.

[0136] Alternatively, the first paper P1 may be label paper in which labels are affixed at predetermined intervals on a backing paper.

[0137] The information terminal device 100 may include a storage box for storing the dropped second paper P2 below the issuing port 102 .
