[0005] Patent Document 1: Japanese Patent Application Publication No. 2001-302073 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] However, this structure is only designed to improve the assembly workability of the parts and does not take into account the situation where multiple different embossing units are prepared and appropriately replaced according to the user's intended use.

[0008] The object of the present invention is to provide a printing apparatus that prepares different first units and second units according to the user's desired use and can selectively assemble the first units and second units, and in each case where the first unit is assembled and the second unit is assembled, the transport path of the printing medium can be set to the most suitable transport path for each unit.

[0009] Methods for solving problems

[0010] To achieve the above objectives, the present invention comprises: a main body having a receiving portion capable of receiving a printed medium; and an opening / closing cover supported on the main body in a manner that allows it to swing between a closed position covering the receiving portion and an open position opening the receiving portion, the opening / closing cover having: a cover guide portion capable of selectively assembling a first unit and a second unit, the first unit supporting a first impression roller in a rotatable manner, the second unit supporting a second impression roller different from the first impression roller in a rotatable manner, and the cover guide portion guiding the printed medium transported by the second impression roller when the second unit is assembled in the opening / closing cover; and a discharge port, on which the printed medium guided by the cover guide portion is discharged in a first direction, a partition wall portion provided in the first unit, the partition wall portion overlapping the cover guide portion in a manner that covers the cover guide portion when the first unit is assembled in the opening / closing cover, and separating the first impression roller side and the discharge port side.

[0011] In the printing apparatus of this invention, a first unit or a second unit is selectively assembled with an opening and closing cover for a receiving section containing the printing medium. The printing medium, guided from the receiving section, is subjected to predetermined processing by the first unit or the second unit and then discharged from the outlet outside the printing apparatus. The first unit has a first impression roller, which transports the printing medium during processing by the first unit. The second unit has a second impression roller, which transports the printing medium during processing by the second unit.

[0012] When the first unit and the second unit perform different processes, the appropriate transport path for discharge from the outlet may differ due to variations in the processing content and the type of printable medium being processed. In this invention, a cover guide is provided in the opening / closing cover to construct appropriate transport paths corresponding to each of these processes. The cover guide guides the printable medium transported by the second impression roller when the second unit is mounted in the opening / closing cover. The cover guide can guide the printable medium using appropriate transport paths for the processing performed by the second unit and the type of printable medium receiving that processing.

[0013] Furthermore, in this invention, a partition wall is provided in the first unit. The partition wall overlaps the cover guide in a manner that covers the cover guide when the first unit is assembled in the open / closed cover state. The partition wall separates the first impression roller side and the discharge port side. When the first unit is assembled in the open / closed cover, the printable medium transported by the first impression roller is transported in a transport path defined by the partition wall rather than the cover guide. The partition wall can guide the printable medium using a suitable transport path for the processing performed by the first unit and the type of printable medium receiving that processing.

[0014] Invention Effects

[0015] According to the present invention, in both the case where the first unit is assembled in the printing apparatus and the case where the second unit is assembled in the printing apparatus, the transport path of the printing medium can be set to the most suitable transport path for each unit.

[0046] Next, a printing apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings. It should be noted that in the following description, as... Figure 1 As shown, with the printing device placed on the table, the directions of front, back, left, right, up, and down are defined.

[0047] (Double tear strip unit)

[0048] Figures 1 to 8 This illustrates a case where a double tear strip unit 40, as a unit for specifically treating the printed medium, is assembled in the printing apparatus 1. Figure 1 In the printing device 1, there is a lower housing 10 as the main body, an upper front cover 11 and an upper rear cover 12 as an opening and closing cover, which together form a roughly rectangular three-dimensional housing 2.

[0049] The lower housing 10 has an operation panel 3 with various operation switches on its front surface, and hooks 4 for engaging the two ends of a shoulder strap (not shown) at the left and right corners from its front surface to the sides. The printing device 1 is hung on the shoulder by the shoulder strap and carried by the user. In this usage configuration, the front (facing forward) becomes the top (facing upward).

[0050] It should be noted that, although omitted in the illustrations, the lower housing 10 is equipped with various connection points, such as a USB port and an RS-232C connector, serving as a communication unit. Besides power supply, it can also connect to printing data input terminals (e.g., personal computers, barcode readers, etc.). Furthermore, in addition to the aforementioned communication units, it also features wired LAN, wireless LAN, and Bluetooth (registered trademark) functions. By using these various communication units to send text data to the printing device 1, it is possible to issue labels containing variable data (text, barcodes).

[0051] In addition, the labeling process can include various labels used in different settings, such as handling tickets and baggage tags for manufacturing / logistics, food display labels and price tags for retail, and specimen labels and drug manual labels for medical use.

[0052] like Figures 2-6 As shown, inside the printing device 1, located below the upper front cover 11, are arranged a rechargeable battery 5, a circuit board 6 and other electronic components related to drive and control, a detection unit 7 including an optical sensor for detecting the presence or absence of labels, a continuous mountain-shaped front tear strip 14 in the left-right direction, an outlet 15 disposed between the rear end of the upper front cover 11 and the front end of the upper rear cover 12, and a print head 16. It should be noted that the print head 16 is positioned opposite to the impression roller 17, which will be described later. The front tear strip 14 is a cutting blade used by the user to manually cut the printed media.

[0053] The upper front cover 11 is provided with a front mounting portion 20 for the cover member 30 to be detachably mounted via a pair of left and right screws 19. The male threaded portion of the screw 19 penetrates the cover member 30 and has a mounting hole 20a (see reference) that is open but not through to the upper surface of the front mounting portion 20 and has a bottomed female threaded hole shape. Figure 6 (B)) Screw coupling.

[0054] Here, assuming the mounting hole 20a of the front assembly 20 is a through hole, depending on the operating environment of the printing device 1, liquids such as water droplets, rainwater, or dust may enter the interior of the front assembly 20 through the through hole. In such a case, the printing device 1 may malfunction. However, by making the mounting hole 20a a non-through bottomed threaded hole, the intrusion of liquids or dust as described above can be prevented.

[0055] Below the upper rear cover 12 is a receiving section 22 that holds the roll 21 wound with the printing medium in a replaceable manner. The upper rear cover 12 functions as an openable cover that can swing between a closed position covering the receiving section 22 and an open position opening the receiving section 22, with a support section 10a located at the rear end of the lower housing 10 as a pivot point. Thus, the upper rear cover 12 can be opened and closed when changing the roll 21 and when changing the unit for specific processing described later.

[0056] Additionally, the rear end of the upper front cover 11 and the front end of the upper rear cover 12 are separated, and a discharge port 15 is provided in the separated portion. The printed media pulled out from the roll 21 and printed is discharged from the discharge port 15.

[0057] On the other hand, the upper rear cover 12 is provided with a double tear strip unit 40 that passes through a pair of left and right sides (in Figure 5 (B) and Figure 6 (B) Only one side is shown in the diagram) The rear assembly part 25 is assembled in a removable manner with screw 24.

[0058] The rear mounting portion 25 forms part of the upper rear cover 12, and has a cover guide portion 25a that is inclined in a front-low and rear-high manner in order to form a unit setting space 26 above, and a mounting hole 25b that is open to the lower surface of the rear mounting portion 25 and is not through, and has an inverted bottom threaded hole shape.

[0059] In this embodiment, the cover member 30 functions as a so-called dummy cover. The cover member 30 is installed in such a way that, when a unit that has undergone specific processing, such as the peeling unit 60 described later, is not mounted on the front mounting part 20, the appearance is not compromised by the exposure of the front mounting part 20.

[0060] like Figure 7 As shown, the double tear strip unit 40 includes a housing 41, an impression roller 17 pivotally supported between the two ends of the housing 41, a partition wall 42 located on the upper surface of the housing 41 and inclined in a front-lower-rear-higher manner, and a mountain-shaped rear tear strip 43 disposed in front of the partition wall 42 and continuous in the left-right direction. The partition wall 42 is fixed to the housing 41 by screws 44. The rear tear strip 43 is a cutting blade for the user to manually cut the printed media after printing.

[0061] The male threaded portion of screw 24 passes through housing 41 and engages with mounting hole 25b of rear assembly part 25.

[0062] Here, by setting the mounting hole 25b of the rear assembly part 25 to a non-through inverted bottom threaded hole shape, it is possible to prevent the intrusion of liquids or dust from the outside.

[0063] Thus, the front assembly 20 and the rear assembly 25 constitute an assembly that can replace various units, in addition to the cover member 30 and the double tear strip unit 40, with the various units that are specifically processed as described later, depending on its usage form (label issuance form).

[0064] In addition, the front assembly part 20 and the rear assembly part 25 constitute an assembly part having mounting holes 20a and 25b respectively, and selectively installing the double tear strip unit 40 and the cover member 30 via screws 19 and screws 24 that engage with mounting holes 20a and 25b.

[0065] Therefore, one of the double tear strip unit 40 and the cover member 30 is selectively installed on the front assembly part 20 or the rear assembly part 25, which serves as an assembly part. This installation is carried out by screws 19 and 24 that engage with mounting holes 20a and 25b. Thus, the user can easily install and remove the double tear strip unit 40 and the cover member 30 through simple screw operations.

[0066] At this time, as Figure 8As shown, the cover member 30 and the double tear strip unit 40 surround part of the outlet 15 from which the label L, which is pulled out of the roll 21 as the printed medium, is discharged.

[0067] The detection unit 7 is provided on the front assembly part 20 to detect the printed medium (i.e., the printed label L pulled out from the roll 21 in this embodiment) discharged from the discharge port 15 via the double tear strip unit 40 assembled on the rear assembly part 25.

[0068] In the case where the detection unit 7 is provided as a unit that can be detachably mounted to the front mounting section 20, rather than being provided on the front mounting section 20 itself, the wiring harness connecting the detection unit 7 and the circuit board 6 also needs to be detached whenever the unit is mounted or detached from the front mounting section 20, which is cumbersome. In this embodiment, since the detection unit 7 is provided on the front mounting section 20, it is not necessary to detach the wiring harness from the detection unit 7 whenever the unit is mounted or detached from the front mounting section 20, thus avoiding cumbersome procedures.

[0069] It should be noted that, as Figure 2 As shown, the detection unit 7 is covered by the upper front cover 11, which is a cover component. Figure 3 The image shows the front cover 11 removed. The interior of the detection section 7 is sealed by a drip-proof sealing member 27, which is an elastic member located on the front mounting section 20, inside the front cover 11. When the front cover 11 is assembled to the lower housing 10, the drip-proof sealing member 27 is in close contact with the back of the front cover 11, thereby preventing the intrusion of liquids or dust from the outside.

[0070] Here, after the user has created the label L using the desired print data, they can pinch the front end of the label L after it is discharged from the outlet 15 and use either the front tear strip 14 or the rear tear strip 43 to cut it off.

[0071] Thus, users can cut the printed label L from roll 21, for example, when label L is a receipt or a discontinuous sticker-like label L with a backing paper, such as a label for a medicine manual.

[0072] Thus, the printing device 1 includes: a housing 2, which is provided with an outlet 15 for discharging a label L; a front mounting portion 20 and a rear mounting portion 25, which are detachably mounted with a unit that surrounds at least a portion of the outlet 15 and performs specific processing on the label L; and a cover member 30, which is detachably mounted to the front mounting portion 20 when the unit is not mounted to the front mounting portion 20.

[0073] Therefore, the label L can be specifically processed (i.e., a cutting operation towards the rear side of the printing device 1) using the double tear strip unit 40 mounted on the rear mounting part 25. In addition, when the cover member 30 is mounted on the front mounting part 20, the cover member 30 covers the front mounting part 20 and forms part of the appearance of the printing device 1, thereby enabling the printing device 1 to maintain an attractive appearance.

[0074] In addition, since the interior of the detection section 7 is sealed by the anti-drip sealing member 27, it can prevent the intrusion of liquids or dust from the outside.

[0075] (Unlined unit)

[0076] Figures 9-14 The illustration shows a case where an unlined unit 50, serving as an adhesive-response unit, is assembled as a unit for specific processing of the printed medium. It should be noted that in the following description, the same reference numerals are used for structures identical to those in the described embodiment, and detailed descriptions thereof are omitted.

[0077] like Figures 9-12 As shown, the printing device 1 is composed of a lower housing 10, an upper front cover 11, and an upper rear cover 12 to form a housing 2. An operation panel 3 and a hook 4 are provided on the surface, and a battery 5, a circuit board 6, a detection unit 7, a front tear strip 14, a print head 16, and an impression roller 17 are provided inside.

[0078] The cover member 30 is attached to the front mounting part 20 of the upper front cover 11 in a detachable manner via a pair of left and right screws 19.

[0079] Below the upper rear cover 12, there is a receiving section 22 that can hold a roll 21, which is a strip of label L without backing paper (release paper) and has an adhesive layer on one side, which is the printing medium, in a replaceable manner.

[0080] In addition, the rear end of the upper front cover 11 and the front end of the upper rear cover 12 are separated, and an outlet 15 for the printed label L is provided in the separated part.

[0081] On the other hand, the upper rear cover 12 is provided with a pair of left and right (in) liningless units 50 via a pair of left and right (in) Figure 11 (B) and Figure 12 (B) Only one side is shown in the diagram) The rear assembly part 25 is assembled in a removable manner with screw 24.

[0082] In this embodiment, the cover member 30 functions as a so-called dummy cover. The cover member 30 is installed in such a way that, when a unit that has undergone specific processing, such as the peeling unit 60 described later, is not mounted on the front mounting part 20, the appearance is not compromised by the exposure of the front mounting part 20.

[0083] like Figure 13 As shown, the linerless unit 50 includes a housing 51 and an impression roller 17 pivotally supported between the two ends of the housing 51. Additionally, an eave-shaped limiting edge 52 extending over the impression roller 17 is integrally provided on the housing 51. The impression roller 17 of the linerless unit 50 uses a material that inhibits the adhesion of the adhesive layer of the printed medium. Furthermore, the surface of the limiting edge 52 is treated to inhibit the adhesion of the adhesive layer of the printed medium.

[0084] The male threaded portion of the screw 24 penetrates the housing 51 and engages with the mounting hole 25b, which is open but not through the lower surface of the rear-facing mounting portion 25 and has an inverted female threaded hole shape.

[0085] Thus, the front assembly 20 and the rear assembly 25 constitute an assembly that can be replaced with other units that have undergone specific processing, in addition to the cover member 30 and the double tear strip unit 40 described above or the linerless unit 50 shown in this embodiment, depending on its usage form (label issuance form).

[0086] In addition, the front assembly part 20 and the rear assembly part 25 constitute an assembly part having mounting holes 20a and 25b respectively, and selectively installing the linerless unit 50 and the cover member 30 via screws 19 and screws 24 that engage with the mounting holes 20a and 25b.

[0087] Therefore, one of the linerless unit 50 and the cover member 30 is selectively installed on the front assembly part 20 or the rear assembly part 25, which serves as an assembly part. This installation is carried out by screws 19 and 24 that engage with mounting holes 20a and 25b.

[0088] Therefore, the user can easily install and remove the unlined unit 50 and the cover member 30 by simple screw operation. In addition, one of the unlined unit 50 and the double tear strip unit 40 is selectively installed in the rear assembly part 25, which serves as the assembly part.

[0089] At this time, as Figure 14 As shown, the cover member 30 and the unlined unit 50 surround part of the outlet 15 from which the strip label L, which is a printed medium without lining paper, is discharged from the roll 21.

[0090] The detection unit 7 detects the label L (in this embodiment, the printed label L is pulled out of the roll 21) that is discharged from the discharge port 15 and whose discharge direction is restricted by the eave-shaped limiting edge 52.

[0091] Here, after the user has created the label L using the desired print data, they can pinch the label L that has been discharged from the outlet 15 and use the front tear strip 14 to cut it off.

[0092] In such a structure, the cover member 30 is assembled to the front assembly part 20 without assembling the unit to the front assembly part 20, which is designed to detachably assemble the unit that performs the specific processing on the label L.

[0093] Thus, the cover member 30 covers the front assembly part 20 and forms part of the appearance of the printing device 1, thereby enabling the printing device 1 to maintain a beautiful appearance.

[0094] (Peeling unit)

[0095] Figures 15-30 The illustration shows a case where a peeling unit 60, serving as a peeling unit, is assembled as a unit for performing specific processing on the printed medium. It should be noted that in the following description, the same reference numerals are used for structures identical to those in the above-described embodiment, and detailed descriptions thereof are omitted.

[0096] like Figures 15-18 As shown, the printing device 1 is composed of a lower housing 10, an upper front cover 11, and an upper rear cover 12 to form a housing 2. An operation panel 3 and a hook 4 are provided on the surface, and a battery 5, a circuit board 6, a detection unit 7, a front tear strip 14, a print head 16, and an impression roller 17 are provided inside.

[0097] The upper unit 70 of the peeling unit 60 is mounted on the front mounting part 20 of the upper front cover 11 in a detachable manner via a pair of left and right screws 19, replacing the cover member 30 described above.

[0098] Below the upper rear cover 12, there is a receiving section 22 that can hold a roll 21, which is a printing medium on which multiple labels L are discretely mounted on a strip of backing paper P and wound up, in a replaceable manner. For example, the labels L can be affixed in a way that allows them to be removed from the backing paper P.

[0099] In addition, the rear end of the upper front cover 11 and the front end of the upper rear cover 12 are separated, and an outlet 15 for the printed label L is provided in the separated part.

[0100] On the other hand, the upper rear cover 12 is provided with a lower unit 80 for the peeling unit 60 via a pair of left and right (in) Figure 17 (B) and Figure 18 (B) Only one side is shown in the diagram) The rear assembly part 25 is assembled in a removable manner with screw 24.

[0101] like Figures 19-21 As shown, from the backing paper P (reference) Figure 30 ) Peel off label L (refer to) Figure 30The peeling unit 60 has an upper unit 70 that replaces the cover member 30 and is mounted to the front assembly 20 by a pair of left and right screws 19, and a lower unit 80 that replaces the double tear strip unit 40 or the unlined unit 50 and is mounted to the rear assembly 25 by screws 24.

[0102] like Figures 22-24 As shown, the upper unit 70 includes a pair of left and right bracket portions 71, a platform portion 72 disposed between the front ends of the bracket portions 71, a discharge roller 73 spanning between the rear ends of the bracket portions 71, and a partition portion 74 that supports the two ends of the discharge roller 73 in a rotatable manner.

[0103] The bracket 71 is supported on the platform 72 by the shaft 71a in a swingable manner.

[0104] The platform 72 spans across the front end of the bracket 71 and has an appearance shape that is roughly the same as the cover member 30, forming a pair of through holes 71b through which the male threaded portion of the screw 19 passes (see reference). Figure 21 (B)).

[0105] Therefore, as Figure 25 and Figure 26 As shown, the upper unit 70 is assembled to the front mounting part 20 of the upper front cover 11 by screws 19. The screws 19 engage with the mounting holes 20a of the upper front cover 11.

[0106] The discharge roller 73 is a driven roller that rotates passively by abutting against the impression roller 17 at the upper rear part of the impression roller 17, thereby pinching and transporting the backing paper P.

[0107] The partition 74 includes a support 75 that supports the discharge roller 73 in a rotatable manner by covering the upper part of the discharge roller 73, and a guide 76 provided in front of the support 75 that separates the discharge outlet 15 into a front discharge outlet 15a and a rear discharge outlet 15b.

[0108] The guide section 76 has an integral guide surface 77 with a ridge 77a located at the lower middle part in the vertical direction and a plurality of ribs 78 that protrude forward from the guide surface 77 and are provided with predetermined intervals in the left and right directions.

[0109] The guide surface 77 is bounded by the ridge portion 77a, with its lower part being a downwardly bent backing paper guide portion 77b and its upper part being a label guide portion 77c that is curved and inclined in a front-low and back-high shape.

[0110] like Figures 27-29 As shown, the lower unit 80 is equipped with screws 24 (see reference). Figure 17 (B) and Figure 18(B) The upper rear cover 12 is equipped with a pair of left and right bracket portions 81 with through holes 81a, a peeling portion 82 that bends the backing paper P to separate it from the label L, and an impression roller 17 that is disposed below the peeling portion 82 and pivotally supported on the bracket portion 81.

[0111] The front end of the peeling section 82 has a cross-sectional shape of R, and the peeling section 82 bends the backing paper P. The bent backing paper P is sandwiched between the impression roller 17 and the discharge roller 73 and is transported. The label L attached to the backing paper P does not bend due to its own rigidity even though the backing paper P is bent, and therefore peels off from the backing paper P. In this way, the lower unit 80 gradually peels off the printed label L from the backing paper P by transporting the bent backing paper P.

[0112] Here, the upper rear cover 12, which serves as a cover supporting the lower housing 10 (which is the main body) and swings between the closed position of the covering and the open position of the receiving portion 22, can be selectively fitted with, for example, a double tear strip unit 40 as a first unit, a linerless unit 50 or a peeling unit 60 as a second unit, which is different from the double tear strip unit 40. Additionally, it includes: a cover guide 25a for guiding the label L transported by the impression roller 17 when the linerless unit 50 is fitted to the upper rear cover 12, or the backing paper P transported by the impression roller 17 when the peeling unit 60 is fitted to the upper rear cover 12; and a discharge port 15 for discharging the label L or backing paper P guided by the cover guide 25a towards the first direction (vertical direction) (upward). A partition wall 42 is provided on the double tear strip unit 40. When the double tear strip unit 40 is assembled to the rear mounting part 25 of the upper rear cover 12, the partition wall 42 is arranged to overlap with the cover guide part 25a in such a way as to cover the cover guide part 25a, and is inclined in a front-low and rear-high shape in such a way as to separate the impression roller 17 and the discharge outlet 15.

[0113] That is, for the upper rear cover 12 that holds the roll 21 on which multiple labels L are discretely pasted on the strip-shaped backing paper P, a double tear strip unit 40 or a peeling unit 60 may be selectively assembled.

[0114] The label L of the backing paper P guided from the receiving section 22 is discharged from the discharge port 15 to the outside of the printing device 1 after being pre-processed by the double tear strip unit 40 or the peeling unit 60.

[0115] When the double tear strip unit 40 is installed, the impression roller 17 of the double tear strip unit 40 is used to transport the liner paper P. When the peeling unit 60 is installed, the impression roller 17 and the discharge roller 73 of the peeling unit 60 are used to transport the liner paper P.

[0116] When the double tear strip unit 40 and the peeling unit 60 perform different processes, the appropriate transport path when the material is processed and the printing medium being processed may differ due to the different processing content and the different printing media.

[0117] Therefore, in order to provide a suitable transport path corresponding to each of these processes, a cover guide 25a is provided on the upper rear cover 12. The cover guide 25a guides the backing paper P transported by the impression roller 17 and the discharge roller 73 when the peeling unit 60 is mounted on the upper rear cover 12. For example, the cover guide 25a can guide the backing paper P after the label L has been peeled off in a form suitable for the process performed by the peeling unit 60 and the type of backing paper P receiving the process.

[0118] Additionally, a partition wall 42 is provided in the double tear strip unit 40. When the double tear strip unit 40 is mounted on the upper rear cover 12, the partition wall 42 overlaps with the cover guide 25a in a manner that covers the cover guide 25a. The partition wall 42 separates the impression roller 17 and the discharge port 15. When the double tear strip unit 40 is mounted on the upper rear cover 12, the backing paper P (or label L) transported by the impression roller 17 is transported in a transport path defined by the partition wall 42 rather than the cover guide 25a.

[0119] The partition wall 42 can, for example, define a transport path that guides the printing medium to the discharge port 15 in a manner suitable for the processing performed by the double tear strip unit 40 and the type of backing paper P (or label L without backing paper) receiving the processing.

[0120] In this way, a suitable transport path can be constructed depending on whether the double tear strip unit 40 is assembled on the upper rear cover 12 or the peeling unit 60 is assembled.

[0121] The cover guide 25a is positioned near the imprint roller 17 and discharge roller 73 mounted on the peeling unit 60 of the upper rear cover 12, and is located in the rear side in the front-to-back direction. It is inclined in a way that the closer it is to the rear, the closer it is to the upper side in the vertical direction.

[0122] In this way, by means of the cover guide 25a, which is inclined from the outlet 15 in a way that is lower in the front and higher in the back, when the peeling unit 60 is assembled on the upper rear cover 12, the printing medium (e.g., backing paper P) can be guided in a form that is suitable for the processing performed by the peeling unit 60 and the type of printing medium receiving the processing.

[0123] In addition, the partition wall 42 is positioned near the imprint roller 17 mounted on the double tear strip unit 40 of the upper rear cover 12 and in the front side in the front-rear direction. It is inclined in a way that the closer it is to the rear side in the front-rear direction, the closer it is to the upper side in the vertical direction, and the inclination angle is smaller than that of the cover guide 25a.

[0124] In this way, since the tilt angle of the partition wall portion 42, which is inclined in a way that is lower in the front and higher in the back, is smaller than the tilt angle of the cover guide portion 25a (gentle tilt), when the double tear strip unit 40 is assembled on the upper rear cover 12, the printed medium can be guided in a form that is suitable for the processing performed by the double tear strip unit 40 and the type of printed medium receiving the processing.

[0125] The dual tear strip unit 40 serves as a cutting blade that can manually cut the printed medium. It is independent of the front tear strip 14 and has a rear tear strip 43 that clamps the discharge port 15. When the dual tear strip unit 40 is installed, the user can selectively use the front tear strip 14 or the rear tear strip 43 to manually cut the discharged printed medium.

[0126] It should be noted that when the peeling unit 60 is assembled as the second unit, it is possible to use a printing medium on which multiple labels L are discretely pasted on a strip of backing paper P, peel (strip) the labels L from the backing paper P, and discharge the backing paper P and the labels L into the discharge port 15 in a state where the backing paper P and the labels L are separated.

[0127] On the other hand, when the linerless unit 50 is assembled as the second unit, the impression roller 17 uses a material that inhibits the adhesion of the adhesive layer of the printed medium, and performs a surface treatment on the surface of the limiting edge 52 to inhibit the adhesion of the adhesive layer of the printed medium. Therefore, it is possible to inhibit the adhesion of the adhesive layer of the printed medium to the impression roller 17 and the limiting edge 52, and to transport the printed medium to the discharge port 15.

[0128] Thus, the front assembly 20 and the rear assembly 25 constitute an assembly that allows for the replacement of the cover member 30 or the peeling unit 60 (upper unit 70) and the aforementioned double tear strip unit 40, the linerless unit 50 or the peeling unit 60 (lower unit 80) according to their usage form (label issuance form).

[0129] That is, the front assembly part 20 and the rear assembly part 25 have mounting holes 20a and 25b, which can selectively install the cover member 30 or the double tear strip unit 40, the cover member 30 and the upper unit 70 and lower unit 80 of the unlined unit 50 and the peeling unit 60 by means of screws 19 and screws 24 that engage with the mounting holes 20a and 25b.

[0130] Therefore, one of the peeling unit 60 (upper unit 70) and the cover member 30 is selectively installed on the front assembly part 20, which serves as an assembly part. This installation is carried out by screws 19 that engage with mounting holes 20a. Similarly, one of the double tear strip unit 40, the linerless unit 50, and the peeling unit 60 (lower unit 80) is selectively installed on the rear assembly part 25, which serves as an assembly part. This installation is carried out by screws 24 that engage with mounting holes 25b. Thus, the user can easily install or remove the peeling unit 60 or the cover member 30, as well as the double tear strip unit 40, the linerless unit 50, and the peeling unit 60, through simple screw operations.

[0131] At this time, as Figure 30 As shown, the peeling unit 60 surrounds part of the outlet 15 from which the labels L, which are peeled off from the backing paper P as printed media, are discharged from the roll 21 on which multiple labels L are discretely pasted on the strip-shaped backing paper P.

[0132] The detection unit 7 is fixed to the bottom surface of the front assembly part 20 and detects the presence or absence of the label L that has been peeled off from the backing paper P and discharged from the discharge port 15 via the peeling unit 60 mounted on the rear assembly part 25 in a non-contact manner. In this way, by setting the detection unit 7 on the front assembly part 20 instead of the peeling unit 60, the cumbersome process of loading and unloading the wire harness from the detection unit 7 every time the peeling unit 60 is loaded and unloaded can be avoided.

[0133] Furthermore, after creating label L using the desired print data, the user can paste the label L, which is discharged from outlet 15, onto the desired object to be pasted.

[0134] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the scope of the technical concept of the present invention is not limited to the embodiments described herein. It is obvious to those skilled in the art that various modifications, alterations, and combinations can be made within the scope of the technical concept of the present invention as set forth in the claims. Therefore, the technology resulting from these modifications, alterations, and combinations also falls within the scope of the technical concept of the present invention.

[0135] In addition to the methods described above, the above-described embodiments and variations can also be appropriately combined and utilized.

[0136] In addition, although not all examples are given, the present invention can be implemented with various modifications without departing from its spirit.
