Description

  The present invention relates to a printing apparatus including a peeling mechanism for peeling a printed label from a mount.

  There is known a printing apparatus capable of switching between an operation mode in which a printed label is stuck on a mount and an operation mode in which a printed label is peeled off from the mount. . Patent Document 1 discloses a label printer that can be switched between a normal issue state and a peeling issue state. The label printer includes a peeling unit having a turning roller and a torsion spring. The peeling unit is movable so that the turning roller is separated from the platen roller in the normal issuing state, and the turning roller is in contact with the platen roller in the peeling issuing state. In the peeling issue state, the turning roller is pressed against the platen roller by the urging force of the torsion spring. The platen roller and the turning roller rotate with the mount sandwiched therebetween, and bend the mount so that the surfaces of the mount on which the label is not attached face each other. Thus, the peeling unit peels the printed label from the mount. In order to appropriately peel the printed label from the mount, it is preferable that the turning roller and the platen roller are appropriately brought into contact with each other.

  In the label printer, the turning roller is pressed against the platen roller by the urging force of the torsion spring. For this reason, the contact between the turning roller and the platen roller may be insufficient. On the other hand, when the urging force of the torsion spring is increased in order to properly contact the turning roller and the platen roller, the user may not be able to easily perform the operation of switching the operation mode. The reason is that when the user switches the operation mode from the peeling issue state to the normal issue state, a strong force is required to separate the turning roller from the platen roller against the urging force of the torsion spring. As described above, in the label printer, it is difficult to achieve both the proper separation of the printed label from the mount and the switching of the operation mode.

The holding mechanism 7 includes shaft support portions 71A and 71B (hereinafter collectively referred to as “a pair of shaft support portions 71”) and fixing members 73A and 73B (hereinafter collectively referred to as “a pair of fixing members 73”). .) Etc.

  As shown in FIG. 8, the shaft support portion 71 </ b> A is provided on the right side of the peeling mechanism 5. The shaft support portion 71A has a groove 711A extending in the front-rear direction on the left side surface. The shaft support portion 71 </ b> B is provided on the left side of the peeling mechanism 5. The shaft support portion 71B has a groove 711B extending in the front-rear direction on the right side surface. Hereinafter, the grooves 711A and 711B are collectively referred to as “groove 711”. The shaft portion 523 of the second member 522A of the peeling mechanism 5 is inserted into the groove 711A of the shaft support portion 71A. The shaft portion 523 of the second member 522B of the peeling mechanism 5 is inserted into the groove 711B of the shaft support portion 71B. The peeling mechanism 5 is movable in the front-rear direction as the shaft portion 523 moves along the grooves 711 of the pair of shaft support portions 71. Further, the peeling mechanism 5 can swing the rear end up and down around the shaft portion 523 by the respective grooves 711 of the pair of shaft support portions 71 supporting the shaft portion 523 in a swingable manner. It is.

  As shown in FIG. 9, the pair of fixing members 73 are plate-shaped. The pair of fixing members 73 are fixed to a pedestal 75 provided on the lower side of the peeling mechanism 5. The fixing member 73 </ b> A is provided on the right side with respect to the left and right center of the base 75. The fixing member 73 </ b> B is provided on the left side with respect to the left and right center of the base 75. The pair of fixing members 73 extend horizontally toward the rear side, extend obliquely upward to the rear from the rear end, bend at the upper end, and extend obliquely downward to the rear. The pair of fixing members 73 can be elastically deformed so as to move downward.

  When the peeling mechanism 5 moves forward according to the movement of the shaft portion 523 along the respective grooves 711 of the pair of shaft support portions 71, the upper end portions of the pair of fixing members 73 are a pair of the frame portions 52. The fixed portion 57 (see FIGS. 5 and 7) is in contact with the rear side, and the rearward movement of the pair of fixed portions 57 is restricted. Thereby, the backward movement of the peeling mechanism 5 is restricted. Further, the peeling mechanism 5 is held in a state of moving until the front end of the peeling mechanism 5 comes into contact with the rear end of the inclined portion 2A (see FIG. 1) of the main body 2 (see FIG. 1). In this case, the swing of the rear end of the peeling mechanism 5 is suppressed by the inclined portion 2A. As shown in FIG. 10, the peeling mechanism 5 holds the first member 521 of the frame portion 52 in a horizontal state. Hereinafter, the state of FIG. 10 in which the peeling mechanism 5 in the accommodated state has moved to the front side is referred to as a “fourth state”.

  On the other hand, when the pair of fixing members 73 are elastically deformed in the direction of moving downward, the peeling mechanism 5 can be moved to the front side. When the peeling mechanism 5 moves rearward along the respective grooves 711 of the pair of shaft support portions 71, between the rear end of the inclined portion 2 </ b> A (see FIG. 1) of the main body portion 2 and the front end of the peeling mechanism 5. A space is formed. In this case, the rear end of the peeling mechanism 5 is in a swingable state. For example, as shown in FIG. 11, the user can swing the rear end upward with the front end of the peeling mechanism 5 as the center. Further, the user can switch the peeling mechanism 5 from the housed state to the protruding state with the rear end of the peeling mechanism 5 being swung upward.

<Procedure for Operating the Printing Apparatus 1 in the Normal Mode>
A procedure for operating the printing apparatus 1 in the normal mode will be described with reference to FIGS. The user pushes down the lever 23 to open the lid member 3. The user attaches a roll to the paper holder 9 (see FIG. 2). The user pushes the support portion 54 of the peeling mechanism 5 toward the frame portion 52 to bring the peeling mechanism 5 into the accommodated state. Next, the user swings the rear end of the peeling mechanism 5 downward, and moves the peeling mechanism 5 forward while the first member 521 of the frame portion 52 is horizontal. The front end of the peeling mechanism 5 is in contact with the rear end of the inclined portion 2 </ b> A of the main body 2. The peeling mechanism 5 is held in the fourth state by the pair of fixing members 73 (see FIG. 9) coming into contact with the pair of fixing portions 57 (see FIGS. 5 and 7) from the rear.

  The user closes the lid member 3 in a state where the mount at the leading end portion of the tape extending from the roll is disposed behind the cutting portion 26A and the printing portion 26B (see FIG. 2). As shown in FIG. 12, in the closing process of the lid member 3, the pair of protrusions 53 (see FIG. 4) of the support portion 54 of the peeling mechanism 5 are respectively plate-like portions of the pair of moving members 341 of the lid member 3. Do not touch 34A. In the closing process of the lid member 3, the pair of engaging members 321 (see FIG. 2) are placed on the upper ends of the engagement extending portions 251 </ b> B of the plate-like members 251 of the pair of regulating members 25 (see FIG. 3). Contact from. The pair of restricting members 25 swings in the direction in which the upper end portion of the base portion 251A moves backward against the biasing force of a spring (not shown). When the pair of engaging members 321 moves into the engaging recess 251D, the pair of regulating members 25 swings in the direction in which the upper end portion of the base portion 251A moves forward by the biasing force of a spring (not shown). The engagement extending portions 251 </ b> B of the pair of regulating members 25 are disposed on the upper side of the pair of engaging members 321. As a result, the pair of engaging members 321 engage with the engagement extending portions 251 </ b> B and the engaging recesses 251 </ b> D of the pair of regulating members 25. Since the pair of restricting members 25 restricts the cover member 3 from returning to the open state by the biasing force of the spring 29A (see FIG. 2), the cover member 3 is closed as shown in FIG. Retained.

  Hereinafter, the distance between the shaft portion 523 and the first roller 32 when the lid member 3 is closed with the peeling mechanism 5 in the fourth state is referred to as a third distance L3. Specifically, the third distance L <b> 3 indicates a distance between an imaginary line passing through the axis of the shaft portion 523 and an imaginary line passing through the axis of the first roller 32. The third distance L3 is greater than the distance (second distance L2) between the shaft portion 523 and the second roller 51 in the accommodated state. For this reason, the 1st roller 32 and the 2nd roller 51 are spaced apart in the front-back direction.

  The user presses the switch 22. Printing by the printing unit 26B is started. The first roller 32 rotates in response to the drive unit rotating the gears 76 and 36 (see FIG. 9). The tape is sequentially fed from the roll and conveyed from the lower side to the upper side. At the same time, the heating element of the printing unit 26B generates heat. As a result, characters and figures are printed on the thermal label. The first roller 32 discharges the tape including the printed thermal label from the discharge port 26C. Since the second roller 51 is separated from the first roller 32 as described above, the second roller 51 does not contact the discharged tape. For this reason, the tape is discharged upward in a stretched state. Therefore, the printed thermal label is discharged in a state where it is stuck on the mount. The discharged tape is cut by the cutting unit 26A.

<Procedure for operating the printing apparatus 1 in the peeling mode>
With reference to FIGS. 14-17, the procedure in the case of operating the printing apparatus 1 in peeling mode is demonstrated. Since the procedure until the roll is mounted on the paper holder 9 is the same as that in the normal mode, the description thereof is omitted.

  The user moves the peeling mechanism 5 backward from the fourth state with the lid member 3 opened. The pair of fixing members 73 (see FIG. 9) is elastically deformed and moves to the front side of the pair of fixing portions 57 (see FIGS. 5 and 7). A space is formed between the rear end of the inclined portion 2 </ b> A (see FIG. 1) of the main body 2 and the front end of the peeling mechanism 5. The rear end of the peeling mechanism 5 is in a swingable state. The user rotates the peeling mechanism 5 around the shaft portion 523 and swings the rear end of the peeling mechanism 5 upward. Further, the user pulls out the support portion 54 of the peeling mechanism 5 from the frame portion 52. The peeling mechanism 5 switches from the housed state to the protruding state (see FIG. 11). Hereinafter, a state in which the lid member 3 is opened and a state in which the protruding peeling mechanism 5 swings the rear end upward (see FIGS. 2 and 11) is referred to as a “first state”. As shown in FIG. 2, in the first state, the first roller 32 of the lid member 3 and the second roller 51 of the peeling mechanism 5 are separated from each other.

  The user mounts the tip portion of the tape extending from the roll behind the cutting portion 26A and the printing portion 26B (see FIG. 2) and below the second roller 51 supported by the support portion 54 of the peeling mechanism 5. Arrange. The user performs an operation of closing the lid member 3 in this state. As shown in FIGS. 14 and 15, in the closing process of closing the lid member 3, the protruding portion 53 </ b> A of the peeling mechanism 5 (FIGS. 4 to 7) The protrusion 53B (see FIGS. 4 to 7) of the peeling mechanism 5 is in contact with the lower side of the plate-like portion 342A of the moving member 342. As the lid member 3 is gradually closed, the pair of projecting portions 53 moves rearward and obliquely downward along the lower side of each plate-like portion 34A of the pair of moving members 34. The peeling mechanism 5 swings the rear end downward about the shaft portion 523. The second roller 51 of the peeling mechanism 5 moves downward and gradually approaches the first roller 32 of the lid member 3 from above.

  As shown in FIG. 16, when the lid member 3 is closed, the pair of engaging members 321 are engaged with the pair of regulating members 25, and the lid member 3 is held in the closed state. The peeling mechanism 5 is held in a state where the first member 521 of the frame portion 52 is slightly inclined with respect to the horizontal direction. The second roller 51 of the peeling mechanism 5 is disposed obliquely above and behind the first roller 32 of the lid member 3. The first roller 32 and the second roller 51 are close to each other. However, in this state, a slight gap is formed between the first roller 32 and the second roller 51. Hereinafter, in response to the cover member 3 being closed from the opened state through the closing process, the protruding peeling mechanism 5 is swung from the first state, and the first roller 32 and the second roller 51 come close to each other. The state of FIG. 16 when the state is reached is referred to as a “second state”. The distance between the first roller 32 and the second roller 51 in the second state is smaller than the distance between the first roller 32 and the second roller 51 in the first state (see FIG. 11).

  Next, the user pushes down the support portion 54 of the peeling mechanism 5 in the second state. As shown in FIG. 17, the peeling mechanism 5 further swings with respect to the second state (see FIG. 16). The pair of protrusions 53 (see FIGS. 4 to 7) of the peeling mechanism 5 are formed in the engagement recesses 251 </ b> C and 252 </ b> B (see FIGS. 8 to 11) of the pair of regulating members 25 (see FIGS. 8 to 11). Move to the back side. Next, the user moves the peeling mechanism 5 to the front side. The pair of protrusions 53 of the peeling mechanism 5 enters the engagement recesses 251 </ b> C and 252 </ b> B of the pair of regulating members 25 from the rear side. At this time, the second roller 51 of the peeling mechanism 5 opposes the diagonally upper rear side of the first roller 32 of the lid member 3 with the mount interposed therebetween. The first roller 32 and the second roller 51 sandwich the mount. The engagement protrusions 252C of the pair of restricting members 25 restrict the rearward movement of the pair of protrusions 53 in a state where the pair of protrusions 53 of the peeling mechanism 5 has entered the engagement recesses 251C and 252B. . The pair of protrusions 53 are engaged with the engagement recesses 251C and 252B, and the state where the first roller 32 and the second roller 51 sandwich the mount is maintained. Hereinafter, the state of FIG. 17 in which the pair of projecting portions 53 of the peeling mechanism 5 in the projecting state is engaged with the engagement recesses 251C and 252B of the pair of regulating members 25 is referred to as a “third state”. The distance between the first roller 32 and the second roller 51 in the third state is smaller than the distance between the first roller 32 and the second roller 51 in the second state (see FIG. 16).

  Hereinafter, the distance between the shaft portion 523 and the first roller 32 in the third state is referred to as a fourth distance L4. Specifically, the fourth distance L4 indicates a distance between a virtual line passing through the axis of the shaft portion 523 and a virtual line passing through the axis of the first roller 32. The fourth distance L4 is greater than the third distance L3 (see FIG. 13) between the shaft portion 523 and the first roller 32 when the lid member 3 is closed with the peeling mechanism 5 in the fourth state. 5 is shortened by moving backward from the fourth state. The fourth distance L4 is substantially the same as the distance (first distance L1) between the shaft portion 523 and the second roller 51 in the protruding state. For this reason, in the third state, the first roller 32 and the second roller 51 can sandwich the mount.

  The user presses the switch 22. Printing by the printing unit 26B is started. The first roller 32 rotates in response to the drive unit rotating the gears 76 and 36 (see FIGS. 8 and 9), and discharges the tape including the printed thermal label from the discharge port 26C. The second roller 51 sandwiches the mount between the first roller 32, bends the mount backward, and discharges the mount backward. As a result, the heat-sensitive label printed in a state of being attached to the mount is peeled off from the mount and discharged upward from the discharge port 26C.

<Main functions and effects of this embodiment>
As described above, the printing apparatus 1 can switch the peeling mechanism 5 from the first state (see FIGS. 14 and 15) to the second state (see FIG. 16) in the closing process in which the lid member 3 is closed. . For this reason, the user can make the peeling mechanism 5 into the 2nd state which can be easily moved to a 3rd state (refer FIG. 17) according to obstruction | occlusion operation of the cover member 3. FIG. Therefore, the user can easily switch the printing apparatus 1 to the peeling mode by performing an operation of closing the lid member 3. Further, in the printing apparatus 1, the pair of regulating members 25 can regulate that the peeling mechanism 5 is switched from the third state to the second state. Accordingly, the printing apparatus 1 can stably operate in the peeling mode.

  The peeling mechanism 5 has a pair of protrusions 53 that protrude outward from both sides in the left-right direction. Each of the pair of regulating members 25 includes engagement recesses 251C and 252B and an engagement protrusion 252C with which each of the pair of protrusions 53 engages. The engagement protrusions 252 </ b> C restrict the separation mechanism 5 from switching from the third state to the second state by prohibiting the movement of the pair of protrusions 53. In this case, the pair of regulating members 25 can regulate the movement of the peeling mechanism 5 on both sides in the left-right direction. Therefore, since the printing apparatus 1 can appropriately maintain the peeling mechanism 5 in the third state, the label can be appropriately peeled from the mount by the peeling mechanism 5.

  The engaging recess 252C is made of resin. For this reason, when each of a pair of protrusion part 53 mutually contacts according to engaging with the engagement recessed part 252C, it can suppress that a pair of protrusion part 53 is shaved by the engagement recessed part 252C.

  Each of the pair of restricting members 25 includes an engagement extending portion 251B and an engagement recess 251D. In a state where the lid member 3 is closed, the pair of engaging members 321 of the lid member 3 engages in the engaging recess 251D and below the engaging extending portion 251B. Thereby, the rotation of the lid member 3 is restricted. As described above, the printing apparatus 1 can appropriately maintain the state in which the accommodating portion 24 is closed by the lid member 3 by the pair of regulating members 25. Further, the pair of regulating members 25 can regulate the rotation of the lid member 3 from the closed state to the opened state on both the left and right sides of the first roller 32. For this reason, the printing apparatus 1 can prevent the cover member 3 in the closed state from rattling. In this case, since the first roller 32 can appropriately press the tape against the printing unit 26B, printing by the printing unit 26B can be stably performed.

  Further, the pair of restricting members 25 can restrict the peeling mechanism 5 from switching from the third state to the second state, and at the same time restrict the lid member 3 from rotating from the closed state to the opened state. For this reason, compared with the case where each function is implement | achieved by another member, a number of parts can be reduced. Furthermore, it is possible to easily keep the distance between the first roller 32 and the second roller 51 constant as compared with the case where the respective functions are realized by separate members.

  In the printing apparatus 1, the backward movement of the peeling mechanism 5 in the fourth state (see FIGS. 12 and 13) is that the pair of fixing members 73 come into contact with the pair of fixing portions 57 of the frame portion 52 from the rear side. Regulated accordingly. In the printing apparatus 1, when the peeling mechanism 5 is in the fourth state, the first roller 32 and the second roller 51 are separated from each other and operate in the normal mode. For this reason, since the printing apparatus 1 can stably maintain the peeling mechanism 5 in the fourth state by the pair of fixing members 73, it can stably operate in the normal mode.

<Modification>
The present invention is not limited to the above embodiment, and various modifications can be made. In the above, the pair of regulating members 25 has the engagement recesses 251C and 252B and the engagement protrusion 252C. When the peeling mechanism 5 is in the third state, the engagement protrusion 252C restricts the movement of the peeling mechanism 5 to the rear side of the pair of protrusions 53, whereby the peeling mechanism 5 is switched to the second state. Regulated that. On the other hand, the pair of restricting members 25 may not have the engagement recesses 251C and 252B and the engagement protrusion 252C. For example, each groove 711 of the pair of shaft support portions 71 may be provided with a restriction portion that restricts the movement of the shaft portion 523 in a state where the peeling mechanism 5 is disposed in the third state. This restricting portion may restrict the peeling mechanism 5 from switching from the third state to the second state by restricting the movement of the shaft portion 523.

  Sites corresponding to the engagement recesses 251C and 252B and the engagement protrusion 252C may be provided in a mechanism different from the pair of restriction members 25. Then, the switching of the peeling mechanism 5 from the third state to the second state may be regulated by engaging another mechanism with the pair of protrusions 53 of the peeling mechanism 5. That is, the member that holds the lid member 3 in a closed state and the member that holds the peeling mechanism 5 in the third state may be separate members.

  In the above, the engagement extending portions 251B of the pair of regulating members 25 regulate the movement of the pair of engaging members 321 of the lid member 3, so that the lid member 3 is brought into the closed state by the urging force of the spring 29A. Restricted rotation to open state. On the other hand, for example, the spring 29 </ b> A may not be provided on the lid member 3. In this case, a member that restricts the rotation of the lid member 3 from the closed state toward the open state may not be provided.

  In the above description, the pair of fixing members 73 restricts the separation mechanism 5 from switching from the fourth state to the third state by restricting the separation mechanism 5 from moving backward from the fourth state. On the other hand, the separation mechanism 5 may be restricted from switching from the fourth state to the third state by a mechanism different from the pair of fixing members 73. For example, each groove 711 of the pair of shaft support portions 71 may be provided with a restriction portion that restricts the movement of the shaft portion 523 in a state where the peeling mechanism 5 is disposed in the fourth state. This restricting portion may restrict the peeling mechanism 5 from switching from the fourth state to the third state by restricting the movement of the shaft portion 523.

  In the above description, the distance between the shaft portion 523 and the first roller 32 in the third state (fourth distance L4) is the distance between the shaft portion 523 and the second roller 51 in the protruding state (first distance L1). It became almost the same. Here, “substantially the same” indicates a state in which the difference between the first distance L1 and the fourth distance L4 is within a distance obtained by adding the respective radii of the first roller 32 and the second roller 51. That is, the first distance L1 and the fourth distance L4 may differ by the length obtained by adding the respective radii of the first roller 32 and the second roller 51. Note that, when the substantially same condition is satisfied, in the third state, the first roller 32 and the second roller 51 can sandwich the mount.

Each of the engagement recesses 251C and 252B and the engagement protrusion 252C of the restriction members 25A and 25B is an example of the “pair of first engagement portions” in the present invention. The pair of engaging members 321 is an example of the “pair of second engaging portions” in the present invention. The engagement extending portions 251B and the engagement recesses 251D of the pair of regulating members 25 are examples of the “pair of third engagement portions” in the present invention.
