Description

The present invention relates to a peeler-equipped printer having a peeler that peels a label from a long mount, and in particular, an operation mode in which the label is peeled and issued one by one, and the label is continuously peeled without being peeled from the mount. The present invention relates to a printer with a peeler that can be switched to an operation mode to be issued.

As a peeler of a printer with a peeler, there is known a structure in which a long mount on which a label is attached is guided while being bent at an angle of a right angle or more via a peeler member such as a peeler shaft. When the mount is transported along a transport path bent at an acute angle, the label attached to the surface of the mount is separated from the mount by the strength (rigidity) of the waist. The label peeled off from the mount is discharged from the label discharge port. The label discharged from the label discharge port is removed therefrom by the operator.

If the label discharged from the label discharge port remains without being removed by the operator and the subsequent label is discharged, the labels stick to each other at the label discharge port, resulting in a paper jam. The harmful effects of Therefore, in the label outlet,
An optical label sensor for detecting whether or not a label remains in the label discharge port is attached.

In the label peeling issue mode in which the labels are peeled off from the mount and issued one by one, printing of the next label is started when the optical label sensor detects that the discharged label is removed. On the other hand, in the continuous label issue mode in which the label is continuously issued with the label attached to the mount, the label is set as it is pulled out from the label discharge port without passing through the path for bending the mount. In this case, since the label or mount is always detected by the label sensor, the label issuing operation cannot be controlled based on the output of the label sensor.

Therefore, it is necessary to execute the label continuous issue mode by performing control processing for invalidating the output of the label sensor or changing the control mode of the label issue operation based on the output of the label sensor. In order to switch the control mode, an operation input for mode switching is required.

Patent Document 1 below discloses a label printer that can recognize an operation mode of label issuance according to a set state of a mount without requiring an operation input. In this label printer, a mount sensor is disposed in a mount discharge path through which the mount is passed in the label peeling issue mode. When the mount is detected by the mount sensor, it is recognized that the peeler is set to the label peeling issue mode.
Japanese Patent Laid-Open No. 08-295323

In a conventional printer with a peeler, in order to switch the label peeling issue mode to the label continuous issue mode, it is not based on a control form that invalidates the output of the label sensor arranged at the label discharge port or the output of the label sensor. A switching operation input for switching to the control mode is required. If the operator forgets to input the mode switching operation, the mount setting state in the peeler does not match the label issuance mode recognized by the printer control system,
A malfunction may occur. If such an operation input can be made unnecessary, the operability of the printer can be improved.

On the other hand, in the method of recognizing the switching of the label operation mode by disposing the mount sensor in the mount discharge path, it is necessary to dispose the mount sensor in addition to the label sensor, which causes an increase in size and cost accordingly. . Further, the mount discharge path is generally arranged in the vicinity of the label discharge port, and there is no room for installation space, so it is difficult to secure the installation location of the mount sensor.

In view of such a point, the problem of the present invention is to cope with the setting state of the peeler without requiring an operation input for switching the label issuing mode or a mount sensor for detecting the label issuing mode. The present invention proposes a printer with a peeler that can execute a label issuing mode.

That is, an object of the present invention is to propose a printer with a peeler that can recognize a peeler setting state based on an output of a label sensor arranged at a label discharge port. Also, in the label continuous issue mode, as in the label peeling issue mode, a printer with a peeler that can directly adopt the operation control based on the output of the label sensor is proposed.

In order to solve the above problems, the peeler-attached printer of the present invention is peeled off from a peeler that can be switched to an operating state in which a label can be peeled off from a long mount, or a retracted state in which no label peeling operation is performed. And a label discharge port for discharging the label remaining on the mount, and a label detection means for detecting whether or not the peeled label remains in the label discharge port, When the peeler is switched to the retracted state, the label detection means switches to the label undetectable state in conjunction with the switching because the detection output continues to be maintained in the output state indicating no label. It is characterized by that.
Also, a peeler that can be switched to an operating state in which the label can be peeled off from the long mount, or a retracted state in which the label peeling operation is not performed,
A label discharge port for discharging the peeled label and the label remaining on the mount,
Label detecting means for detecting whether or not the label after peeling remains in the label discharge port,
The label detection means is a label detection that is held with a predetermined urging force so as to stop at a first position arranged across the label discharge port, and can be pushed by the discharged label to turn in the label discharge direction. A lever and a lever detector for detecting whether the label detection lever is in the first position;
When the peeler is switched to the retracted state, the label detection lever moves in conjunction with the switching to a second position that does not interfere with the label discharged from the label discharge port. A part of the label detection lever is always held in the detection area of the lever detection unit, thereby forming a label undetectable state in which the label detection means is held in an output state indicating no label. It is characterized by.

In the printer with a peeler according to the present invention, when the peeler is switched to the retracted state, the label detecting means is switched to the label undetectable state in conjunction with this, and the detection output is not changed and is always kept in the label-free state. to continue. From this detection output state, it can be recognized that the peeler has been switched to the retracted state, that is, the label issuing mode has been switched to the label continuous issuing mode. For example, even if the mount is transported and discharged from the label discharge port, the detection output that normally changes does not change. Based on this, it can be recognized that the peeler has switched to the retracted state.

Further, since the detection output of the label sensor always indicates that there is no label at the label discharge port, it is possible to execute a continuous label issue mode in which labels are continuously issued based on this detection output. Therefore, the label peeling issue mode and the label continuous issue mode can be realized by the same operation control form based on the detection output of the label detection means without doing anything special.

Next, in the present invention, the label detection means is a photosensor that detects the presence / absence of a label based on detection light reflected or blocked by a label, and at least the light receiving portion of the photosensor is shielded so that the label cannot be detected. It has the shielding member which can form.

For example, in the case of using a reflection type photosensor, if the light receiving unit is shielded so that the reflected light is not received, the photosensor detection output is always kept in an unlabeled output state. Based on this output state, it can be recognized that the peeler has been switched to the retracted state, that is, the label issuing mode has been switched to the continuous label issuing mode.

Here, in the case where the peeler includes a mount pressing position capable of transporting the mount after the label is peeled off and a mount pressing roller capable of moving between the retracted position retracted from the mount pressing position, The operation state of the peeler is a state where the mount pressing roller is held at the mount pressing position, and the retracted state of the peeler is a state where the mount pressing roller is switched to the retracting position. In this case, an interlocking mechanism that moves the shielding member in conjunction with the movement of the mount pressing roller may be disposed.

In this case, a turning member that supports the mount pressing roller is disposed, and the turning member can be turned between a first turning position and a second turning position, and the first turning The mount presser roller may be in the mount presser position at the position, and the mount presser roller may be in the retracted position at the second turning position. As the interlocking mechanism, a cam mechanism that converts the turning motion of the turning member into the moving motion of the shielding member can be used.

Next, in the present invention, the label detection means is held by a predetermined urging force so as to stop at the first position arranged across the label discharge port, and is pressed by the discharged label. And a label detection lever that can pivot in the label discharge direction, and a lever detection unit that detects whether or not the label detection lever is in the first position. When switched to the label unpeelable state, in conjunction with the switching, the label is moved to a second position that does not interfere with the label discharged from the label discharge port, and at the second position, the label detection lever A part is always held in the detection area of the lever detection unit, and the label detection impossible state is formed.

When the peeler is switched to the retracted state, that is, when the label issuing mode is switched to the label continuous issuing mode, the label detection lever moves to the second position, and a part thereof is always held within the detection area of the lever detection unit. Is done. As a result, the detection output of the lever detection unit continues to be held in a state indicating no label where the detection lever is stopped at the first position. Based on the output state that does not change, it can be recognized that the peeler has been switched to the retracted state, that is, the label issuing mode has been switched to the label continuous issuing mode. Also, since the detection output does not change and there is always no label, the continuous label issuance mode is executed in the same control form as in the label peeling issuance mode based on this detection output without any special action. can do.

Here, even when the label detection lever moves to the second position, in order to keep a part of the label detection lever within the detection area of the lever detection unit, the label detection lever is detected by the lever detection unit. What is necessary is just to be able to turn to the said 2nd position from the said 1st position centering on the site | part located in an area | region.

In the case where the peeler includes a mount pressing position capable of transporting the mount after the label has been peeled and a retraction position retracted from the mount pressing position, the peeler The operating state is a state where the mount pressing roller is held at the mount pressing position, and the retracted state of the peeler is a state where the mount pressing roller is switched to the retracted position.

In this case, a swiveling member that supports the mount pressing roller is disposed, and the swiveling member is centered on a swiveling center line that passes through the detection region of the lever detecting unit, and the second swiveling position and the second swiveling position are set. Between the swiveling positions, the mount pressing roller is set to the mount pressing position at the first turning position, and the mounting press roller is set to the retracted position at the second turning position.

The label detection lever is supported by the pivot member, and the pivot member is the first member.
When the label detection lever is in the first position at the turning position, and the turning member is turned to the second turning position, the label detection lever may be switched to the second position.

Here, the label detection lever supported by the swivel member in the first swivel position is between the label discharge port and a mount discharge path for discharging the mount after the label is peeled off. It is desirable to be arranged in. If it does in this way, a label detection lever can be made to function as a guide member which guides a label after peeling from a mount so that it may not go to the mount side again.

Further, it is desirable to form a guide portion for guiding the label in the label discharge direction, such as a step, on the label contact surface of the label detection lever on which the discharged label contacts. Furthermore, the label contact surface is set so that the label sliding resistance in the label discharging direction is smaller than the label sliding resistance in the opposite direction so that the label can be smoothly guided toward the label discharge port. It is desirable that Further, the surface shape is formed so that the label contact surface contacts the label in a point contact or line contact state so that the label does not stick to the label contact surface of the label detection lever. It is desirable .

Next, in the printer with a peeler according to the present invention, the drive control unit that drives and controls the print head and the paper feed mechanism has the label detection means output the label after the paper feed operation of the predetermined amount by the paper feed mechanism. When the state is switched to the state, it is determined that the peeler is in the operating state, and otherwise, it is determined that the peeler is switched to the retracted state.

In the printer with a peeler according to the present invention, the state of the peeler can be recognized based on the output state of the label detection means. Based on this, the label operation mode can be switched to the label peeling issue mode and the label continuous issue mode. Therefore, it is not necessary to attach a sensor for detecting switching of the operation mode such as a mount sensor.

Also, there is no need for operation mode switching input operation, control processing for invalidating the detection output of the label detection means, etc., even if the label issuance mode changes, the operation control is output without any special action. The same can be done based on

Further, the state of the peeler is directly detected by the label detecting means, and the operation mode is switched based on this. Therefore, there is no adverse effect that the actual paper set state of the peeler does not match the designated label issuing operation mode.

Hereinafter, embodiments of a printer with a peeler to which the present invention is applied will be described with reference to the drawings.

[Embodiment 1]
1 to 9 show a peeler-equipped printer according to Embodiment 1 to which the present invention is applied.

FIG. 3 is a schematic cross-sectional view showing a portion of the recording paper transport path, and FIG. 4 is a schematic cross-sectional view showing a portion of the recording paper transport path with the opening / closing lid opened.
With reference to these drawings, the overall configuration of the peeler-equipped printer will be described first.

As shown in FIG. 1, the peeler-equipped printer 1 has a flat rectangular parallelepiped shape that is long in the front-rear direction as a whole. An open / close lid 4 and an open / close peeler unit 10 are disposed in the latter half of the upper surface of the printer outer case 2 of the printer 1 with peeler. A mount discharge port 11 extending in the printer width direction is formed between the opening / closing lid 4 and the peeler unit 10. The peeler unit 10 is formed with a label discharge port 12 extending in the printer width direction.

As shown in FIG. 2, the opening / closing lid 4 is supported in a state in which a rear end portion thereof can pivot about a support shaft 13 on the printer main body side extending in the printer width direction. The open / close lid 4 can pivot between a closed position 4A shown in FIGS. 1 and 3 and an open position 4B shown in FIGS. When the opening / closing lid 4 is opened, the roll paper storage unit 15 formed inside the rear portion of the printer is opened. As shown in FIG. 4, the front end portion of the peeler unit 10 is also supported so as to be pivotable about a support shaft 16 on the printer main body side extending in the printer width direction. The peeler unit 10 can pivot between a closed position 10A shown in FIGS. 1 and 3 and an open position 10B shown in FIGS.

The opening / closing lid 4 and the peeler unit 10 are locked at the closed positions 4A and 10A by a lock mechanism (not shown). A lid open button 17 is arranged on the right side of the opening / closing lid 4, and by operating this, the peeled state can be released and the peeler unit 10 and the opening / closing lid 4 can be opened in this order.

As shown in FIG. 3, the roll paper storage unit 15 formed inside the printer has a roll paper 1
4 is stored. The roll paper 14 has a configuration in which a long paper is wound into a roll. When the label is issued, the roll paper 14 is a roll of a long mount on which a label is attached at a predetermined interval.

As indicated by a two-dot chain line in FIG. 3, inside the printer, the paper 14 </ b> A fed out from the roll paper 14 loaded in the roll paper storage unit 15 is loaded with a mount outlet 11 and a label formed at the center of the upper surface of the printer. A conveyance path 18 that leads to the discharge port 12 is formed. This transport path 1
A thermal head 19 is arranged at a position midway 8. Printing surface 1 of the thermal head 19
9a and the platen roller 20 mounted on the opening / closing lid 4 side are pressed against each other by a predetermined force from the rear side of the thermal head 19 with the paper 14A interposed therebetween.

As shown in FIGS. 5B, 6C, and 8 to be described later, the sheet 14A is a long mount 14b and a fixed length that is affixed to the surface at fixed intervals. When the paper 14A is provided with the label 14c having the width, the thermal head 19 prints on the surface of the label 14c while the paper 14A is conveyed by the platen roller 20. The printed paper 14A is conveyed and discharged along either the label discharge path 18a guided to the label discharge port 12 or the mount discharge path 18b guided to the mount discharge port 11.

In the label discharge path 18a, a reflective photosensor 21 is disposed as a label detection means for detecting whether or not the label 14c remains in the label discharge port 12. In this example, the photo sensor 21 is attached to the peeler unit 10. Further, a cutter plate 22 is disposed in the label discharge path 18a, and the sheet 1 discharged from the label discharge port 12 is provided.
4A can be cut manually. This cutter plate 22 is also the peeler unit 10.
Is attached. These mounting positions will be described later (see FIGS. 5 to 7).

A peeler shaft 23 extending in the printer width direction is disposed at a branch point between the label discharge path 18a and the mount discharge path 18b. The peeler shaft 23 is a small-diameter shaft that guides the paper 14 </ b> A to the rear of the printer by curving the paper 14 </ b> A at a right angle or more, and is mounted on the opening / closing lid 4 side. Peeler shaft 2
3 is pressed against the platen roller 20 located on the lower rear side of the base plate 3 from the upper side in a state where the base sheet pressing roller 24 attached to the peeler unit 10 side can be rotated.

When the paper 14A is curved by the peeler shaft 23, the label 14c attached to the surface of the mount 14b is peeled off and separated from the mount 14b by its own waist strength (rigidity). After separation, the peeled label 14c is conveyed to the label discharge path 18a guided to the label discharge port 12. On the other hand, the mount 14 b is conveyed to the mount discharge path 18 b guided to the mount discharge port 11 while being sandwiched between the platen roller 20 and the mount pressing roller 24. Thus, in this example, the peeler 30 is constituted by the peeler unit 10 (mounting presser roller 24) attached to the printer main body side and the peeler shaft 23 attached to the opening / closing lid 4 side.
Is configured.

Here, the lid open button 17 is pressed to release the lock (not shown) and the peeler unit 1
When 0 is opened, the mount pressing roller 24 mounted thereon is separated from the outer peripheral surface of the platen roller 20, so that the mount discharge path 18b connected to the mount discharge port 11 is opened. When the peeler unit 10 is opened, the opening / closing lid 4 can be opened. When the opening / closing lid 4 is opened, the platen roller 20 mounted thereon is separated from the thermal head 19 and the transport path 18 is opened. When the roll paper 14 is replaced, a new roll paper 13 is put in this state, the paper 14A is pulled out therefrom, and then the opening / closing lid 4 and the peeler unit 1 are pulled out.
Close in order of zero. As a result, a paper set state in which the paper 14A passes between the thermal head 19 and the platen roller 20 and is drawn out to the label discharge port 12 or the mount discharge port 11 is formed.

(Peeler configuration)
Next, the configuration of the peeler 30 will be described in detail with reference to FIGS. 5 and 6. Fig.5 (a) is a perspective view which shows the peeler unit 10 switched to the operation state which performs label peeling operation | movement, FIG.5 (b) is the schematic sectional drawing. In addition, FIG. 6A and FIG.
It is the perspective view and partial perspective view which show the peeler unit set to the retracted state which does not perform peeling operation | movement, FIG.6 (c) is the schematic sectional drawing.

First, the peeler unit 10 attached to the printer main body side has a unit frame 31 that can be turned up and down around a support shaft 16 on the printer main body side, and a mount pressure roller support frame 35 that supports the mount pressure roller 24. (The swivel member), and the mount pressing roller support frame 35 is supported by the unit frame 31 in a state in which it can be swung up and down.

When the peeler unit 10 is closed with the mount pressing roller support frame 35 set at the upper first turning position 35A shown in FIGS. 5A and 5B, the mount pressing roller 24 is pressed from above the platen roller 20 with the sheet 14A interposed therebetween. Is set at the position 24A. This state is a state in which the mount 14a can be conveyed toward the mount discharge port 11 via the peeler shaft 23, and is a state in which the peeler capable of performing the label peeling operation is operable.

On the other hand, the mount presser roller support frame 35 is provided on the lower second side shown in FIGS. 6 (a) to 6 (c).
When the peeler unit 10 is closed with the swivel position 35B set, the mount press roller 2
4 does not hit the platen roller 20, but is set at the retracted position 24B retracted to the front position. This state is a state in which the mount 14a cannot be discharged toward the mount discharge port 11 via the peeler shaft 23, and is a retracted state of the peeler 30 in which the label peeling operation is not performed.

Accordingly, in the state where the peeler unit 10 is opened as shown in FIGS. 2 and 4, the mount pressure roller support frame 35 is set in a state where it is turned from the first turning position 35 </ b> A to the second turning position 35 </ b> B. When the unit 10 is closed, the peeler 30 can be switched to the retracted state.

Next, the structure of each part will be described in detail. The unit frame 31 that can turn up and down includes a connecting portion 32 that extends in the printer width direction, and left and right arm portions 33 and 34 that are bent at right angles from both ends of the connecting portion 32 to the back of the printer. . Shaft hole 3 at the front end of arms 33 and 34
3a and 34a are formed, and a support shaft 16 on the printer main body side is inserted therethrough in a rotatable state, and the unit frame 31 can turn up and down around the support shaft 16. The unit frame 31 is always urged upward (in the opening direction) by a torsion spring (not shown) attached to the support shaft 16.

Between the left and right arm portions 33 and 34 of the unit frame 31, a mount pressing roller support frame 35 is attached in a state in which it can pivot in the vertical direction. The mount pressing roller support frame 35 includes a connecting portion 36 extending in the width direction of the printer, and left and right arm portions 37 and 38 extending bent at right angles from both ends to the front of the printer. A mount pressing roller 24 is attached to the lower side of the connecting portion 36 in a rotatable state. Cylindrical support shafts 39 and 40 project outside the printer width direction at the front end portions of the left and right arm portions 37 and 38, and these support shafts 39 and 40 correspond to the left and right arm portions 33 of the unit frame 31. , 34 in a rotatable state.

A cutter plate 22 is attached to the rear surface of the connecting portion 32 extending in the printer width direction of the unit frame 31, and this surface serves as a label guide surface 22a. The front surface of the connecting portion 36 of the mount pressing roller support frame 35 is also a label guide surface 36a. In a state in which the mount pressing roller support frame 35 is in the first turning position 35A, the label guide surfaces 22a and 36a are opposed to each other from the front-rear direction of the printer at a constant interval, and thereby the label discharge path 1
8a and label outlet 12 are defined.

Here, as shown in FIG. 6B, a torsion coil spring 42 is attached to the support shaft 39, and the mount pressing roller support frame 35 is moved upward (first rotation position 35A) by one end of the torsion coil spring 42. ). The other end of the torsion coil spring 42 is connected to a lock plate 43 movably attached to a lower portion of the arm portion 37 and urges the lock plate 43 upward. Thus, the lock plate 43 is attached to the arm portion 37 so as to be movable up and down.

When the mount presser roller support frame 35 is turned toward the second turning position 35B, the end of the roller shaft 24a of the mount presser roller 24 supported thereon pushes up the hook 43a of the lock plate 43 and locks on the rear side. Is done. As a result, the presser roller support frame 35 is moved to the second turning position 35.
Therefore, a state in which the mount pressing roller 24 held there is set at the retracted position 24B is formed. In this locked state, the lock plate 4
When 3 is pushed up against the spring force, the mount presser roller 2 is released from the hook 43a of the lock plate 43.
4 ends of the roller shaft 24a. As a result, the mount pressing roller support frame 35 returns to the first turning position 35 </ b> A by the spring force of the torsion coil spring 42. In this way, the mount pressing roller support frame 35 can move between the first turning position 35A and the second turning position 35B.

Next, a rectangular opening 22b is formed at the right corner of the cutter plate 22 attached to the connecting portion 32 of the unit frame 31. From here, light is received and emitted by the reflective photosensor 21 for label detection. The surface 21a is exposed. A substantially rectangular shielding plate 44 is attached to the rear side of the cutter plate 22 so as to be slidable in the printer width direction.

FIG. 7A and FIG. 7B are explanatory views showing a cam mechanism for sliding the shielding plate 44. Referring to these figures, the arm 44a extends from the right end portion of the shielding plate 44 toward the support shaft 40 of the right arm portion 38 of the mount presser roller support frame 35, and the tip of the arm 44a. Is formed with a cam follower 44b. A cam surface 40 a extending in a spiral shape is formed on the circular outer peripheral surface of the support shaft 40, and a cam follower 44 b is pressed against the cam surface 40 a by a force of a spring 45 in a slidable state. Such cam surface 40
By the cam mechanism comprising a and the cam follower 44b, the shielding plate 44 is interlocked with the operation of the mount pressing roller support frame 35 turning from the first turning position 35A to the second turning position 35B.
It slides from the shielding release position 44A shown in (a) to the shielding position 44B shown in FIG. 7 (b).

The shielding plate 44 at the shielding release position 44 </ b> A is located on the side of the opening 22 b where the light emitting / receiving surface 21 a of the photosensor 21 is exposed. At this time, as shown in FIG. 5A, the photosensor 21 can receive reflected light for detection through the opening 22b. When the shielding plate 44 moves while sliding to the shielding position 44B, the lower half portion of the opening 22b is shielded by the shielding plate 44 as shown in FIG. As a result, the lower light receiving surface portion of the light receiving / emitting surface 21a of the photosensor 21 is covered and hidden. In this state, the photosensor 44 cannot receive the reflected light for detection, and therefore it is always kept in the detection output state indicating no label.

In addition, the photosensor 21 of this example is attached so that the light emitting / receiving surface 21a may be inclined downward with respect to the vertical surface, as can be seen from FIGS. 5 (b) and 6 (c). . If the photo sensor 21 is attached in this way, it is possible to prevent external light from entering the light receiving / emitting surface 21a through the label discharge port 12 and the like, and the photo sensor 21 from being in a false detection state.

(Drive control system)
FIG. 8 is a schematic block diagram of the drive control system of the printer 1 with peeler. The drive control system
A drive control unit 51 composed of a microcomputer or the like is provided, and a print command, label printing information, and the like are supplied to the drive control unit 51 from a host device (information processing terminal). When receiving a print command, the drive control unit 51 first identifies whether the operation mode is the label peeling issue mode or the label continuous issue mode from the detection output of the photosensor 21. And
In accordance with each operation mode, the drive motor 5 of the platen roller 20 is connected via a motor driver 52.
3 (paper transport mechanism) is driven and controlled to feed the paper 14A. Further, in synchronization with the feeding operation, the thermal pad 19 is driven via the head driver 55 to perform predetermined printing on the label. In the feeding operation of the paper 14A, the presence / absence of the paper 14A and the position of the label 14c are recognized based on the detection output of the paper detection sensor 54 disposed on the downstream side of the platen roller 20.

(Label issuing operation)
FIG. 9 is a schematic flowchart showing the label issuing operation by the printer 1 with the peeler. The label issuing operation and the operation of the peeler 30 will be described according to this flowchart.

The label is issued in one of an operation mode of a label peeling issue mode in which labels are issued one by one and a label continuous issuing mode in which labels are continuously issued without being peeled from the mount. In any case, the roll paper storage unit 15 has the roll paper 14 as
A sheet 14A having a configuration in which a label 14c of a predetermined length is attached to a long mount 14b at a predetermined interval is loaded into a roll.

In the label peeling issue mode in which the labels 14c are issued one by one, the peeler unit 10 is closed with the mount pressing roller support frame 35 of the peeler unit 10 set at the first turning position 35A (step ST1 in FIG. 9). . As a result, FIG. 5 (a) and FIG. 5 (b)
As shown, the paper 14A is bent downward from the upper outer peripheral surface portion of the peeler shaft 23,
It is sandwiched between the base sheet pressing roller 24 and the platen roller 20, and the leading end portion is pulled out from the base sheet discharge port 11.

When the label issuance command is received, the conveyance of the sheet 14A is started and the first label is printed (step ST2 in FIG. 9). The mount 14c is discharged from the mount discharge port 11. In the peeler shaft 23, each label 14c attached to the mount 14b is not curved together with the mount 14b due to its waist strength (rigidity). It peels from the surface of the mount and goes to the label discharge port 12 through the upper label discharge path 18a.

The light receiving / emitting surface 21a of the photosensor 21 for label detection is exposed on the label guide 22a on the front side of the printer that defines the label discharge path 18a. When the peeled label 14c reaches the label outlet 12, the photosensor 21 detects the label 14c.

When the detection output of the photosensor 21 for label detection changes to a state with a label after a predetermined amount of conveyance operation has been performed from the start of the label issuing operation, the drive control unit 51 performs the label peeling operation. It can be recognized that it is set to the operating state for performing
Based on this, the label issuing operation mode is set to the label peeling issuing mode (step ST3 → ST4 in FIG. 9).

Thereafter, the conveyance of the paper 14A is stopped, and after waiting for the label 14c to be removed, it waits. When the label 14c is removed by the operator, the detection output of the photosensor 21 returns to a state without a label. When the label 14c is transported to the position where it is removed, the leading end position of the next label has passed the printing position of the thermal head 19. For this reason, in order to once return the leading end position of the next label to the printing position of the thermal head 19, the paper 14
A is conveyed in the reverse direction. Thereafter, the printing operation (label issuing operation) is resumed from the leading edge of the next label (steps ST5 and ST6 in FIG. 9). In this way, labels are created and issued one by one. When the next label print command is not received from the host device, the process returns to the state of waiting for the next printing.

Next, the operation of the continuous label issue mode for issuing the labels 14c continuously will be described. In this case, the peeler unit 10 is opened and the mount pressing roller support frame 35 is moved to the second turning position 3.
Set to 5B. When the peeler unit 10 is closed in this state, FIGS.
), And the sheet 14A is not bent by the peeler shaft 23.
It is set in a state of being pulled upward along the label guide surface 22a (step ST1 in FIG. 9).

Further, when the mount pressing roller support frame 35 is set at the second turning position 35B, the shielding plate 44 of the label guide surface 32a slides from the shielding release position 44A to the shielding position 44B in conjunction with this operation, and the photosensor 21 It switches to the state which shielded the lower half part of the opening part 22b from which the light emitting / receiving surface 21a is exposed. Therefore, the lower light receiving surface portion of the light receiving / emitting surface 21a of the photosensor 21 is covered and the detection reflected light from the paper 14A cannot be received. As a result, the photosensor 21 is always kept in the detection output state indicating no label.

When the label issuance command is received, the conveyance of the sheet 14A is started and the first label is printed (step ST2 in FIG. 9). Since the peeler 30 does not function, the label 14c is discharged while attached to the mount 14b.

In this case, even after a predetermined amount of transport operation has been performed since the start of the label issuing operation,
The detection output of the photosensor 21 for label detection does not change to a state with a label. Therefore, the drive control unit 51 can recognize that the peeler 30 has been switched to the retracted state because the output state of the photosensor 21 is held in a state without a label. Based on this, the label issuing operation is performed in the label continuous issuing mode (steps ST3 to ST7 in FIG. 9).

Thereafter, the printing operation for the label 14c on the mount 14b is continuously performed based on the print command supplied from the host device without interruption of the conveyance of the paper 14A. In this way, the printed label 14c is continuously discharged while being stuck on the mount 14b. When printing is completed (step ST8), the process returns to the next print waiting state.

Even when printing is performed on a roll paper 14 on which a general long recording paper is wound instead of a label, the mount pressing roller support frame 35 is switched to the second turning position 35B, and the recording paper is It is set in a state of being pulled upward along the label guide surface 22a. In this case,
As in the case of issuing labels continuously, printed recording paper is continuously discharged.

As described above, in the printer 1 with the peeler in this example, when the peeler 30 is switched to the retracted state, the shielding plate 44 moves in conjunction with this, and the light receiving surface portion of the light receiving surface 21a of the reflective photosensor 21 for label detection. Shield. Even if the discharging operation of the label 14c is performed in this state, the detection output of the photosensor 21 is always kept in a state without a label and does not change to an output state with a label.

Therefore, the state of the peeler 30 can be recognized using the photosensor 21 for label detection without requiring a sensor such as a mount sensor for detecting the switching of the operation mode, and the operation mode is determined based on this. Can be set. For this reason, it is possible to detect the switching of the operation mode without causing an increase in cost and an increase in size, and an operation mode switching operation is unnecessary. Furthermore, since the actual state of the peeler 30 and the set operation mode always coincide with each other, there is no problem that the operator makes a mistake in the mode setting and the label is clogged in the label discharge port.

In this example, the reflection type photosensor 21 is used as the label detection means, but a transmission type photosensor in which the light emitting element and the light receiving element are arranged to face each other can also be used.

In this example, the light receiving surface portion of the light receiving / emitting surface 21a of the reflective photosensor 21 is covered by the shielding plate 42, but the entire light receiving / emitting surface 21a may be covered. Of course, a shielding member that covers the entire photosensor 41 may be used.

Furthermore, in this example, the shielding plate is slid through the cam mechanism, but it goes without saying that the shielding plate may be moved using an interlocking mechanism other than the cam mechanism. The moving form of the shielding plate is not limited to the linear slide, and the shielding plate may be moved between the shielding position and the shielding release position along a turning, rotating, or other movement locus. In addition to this, it is also possible to use a shielding member that opens and closes like a shutter mechanism or a diaphragm mechanism of a camera.

[Embodiment 2]
Next, FIG. 10 to FIG. 15 show a printer with a peeler according to Embodiment 2 to which the present invention is applied.

(overall structure)
FIG. 10 is an external perspective view of the printer with peeler according to the present embodiment. FIG. 11 is an external perspective view showing a state in which the opening / closing lid is opened, and shows a state in which the lower half portion of the printer outer case is removed. FIG. 12 is a schematic sectional view showing the recording paper conveyance path. First, the overall configuration of a printer with a peeler will be described with reference to these drawings.

The basic configuration of the printer with peeler 100 is the same as that of the printer with peeler 1 according to the first embodiment. As shown in FIG. 10, the printer 100 has a flat rectangular parallelepiped shape that is long in the front-rear direction. An open / close lid 104 and an open / close peeler unit 110 are disposed on the upper half of the upper surface of the printer outer case 102 of the printer 100 with peeler. Opening / closing lid 1
A mount discharge port 111 extending in the printer width direction is formed between 04 and the peeler unit 110. The peeler unit 110 has a label discharge port 112 extending in the printer width direction.

The opening / closing lid 104 has a support shaft 113 on the printer main body side whose rear end extends in the printer width direction.
Is supported so as to be able to turn around. The opening / closing lid 104 is in a closed position 104 shown in FIG.
It can turn between A and the open position 104B shown in FIG. When the opening / closing lid 104 is opened, the roll paper storage portion 114 formed inside the rear portion of the printer is opened.
The peeler unit 110 is also supported at its front end portion so as to be pivotable about a support shaft 116 on the printer body side extending in the printer width direction. The peeler unit 110 can pivot between a closed position 110A shown in FIG. 10 and an open position 110B shown in FIG.

The opening / closing lid 104 and the peeler unit 110 are locked at the closed positions 104A and 110A by a lock mechanism (not shown). A lid open button 117 is arranged on the right side of the opening / closing lid 104, and by operating this, the locked state is released and the opening / closing lid 1 is opened.
04 and the peeler unit 110 can be opened.

As shown in FIG. 12, roll paper 115 is stored in a roll paper storage portion 114 formed inside the printer. The roll paper 115 has a configuration in which a long paper is wound into a roll. In the case of issuing a label, a roll paper 115 is used in which a long mount on which labels are attached at regular intervals is wound into a roll.

As shown by a two-dot chain line in FIG. 12, inside the printer, the paper 114A fed out from the roll paper 115 loaded in the roll paper storage unit 114 is loaded with a mount discharge port 111 and a label formed at the center of the upper surface of the printer. A conveyance path 118 that leads to the discharge port 112 is formed.
A thermal head 119 is disposed in the middle of the transport path 118. The printing surface 119a of the thermal head 119 and the platen roller 12 mounted on the opening / closing lid 104 side.
0 is pressed against each other by a predetermined force from the rear side of the thermal head 119 with the paper 114A interposed therebetween.

As shown in FIGS. 13 to 15 described later, the sheet 114A is a long mount 114b,
In the case where the sheet 114A is provided with labels 114c having a certain length and width adhered to the surface at regular intervals, the sheet 114A is conveyed by the platen roller 120,
Printing is performed on the surface of the label 114c by the thermal head 119. The printed paper 114A is conveyed and discharged along either the label discharge path 118a guided to the label discharge port 112 or the mount discharge path 118b guided to the mount discharge port 111.
As will be described later, a label detection means including a label detection lever 139 and a photocoupler 140 for detecting whether or not a label remains in the label discharge port 112 is disposed in the label discharge path 118a. In this example, label detection means is attached to the peeler unit 110.

In the mount discharge path 118b connected to the mount discharge port 111, a label producing sheet 114A is provided.
A peeler roller 121 is disposed to be bent at a right angle or more and conveyed to the rear of the printer. A backing paper transporting roller 122 attached to the printer main body side is disposed behind the peeler roller 121. The backing paper transporting roller 122 has a peeler unit 1 attached thereto.
A base sheet pressing roller 123 attached to the side 10 is pressed in a state where it can be rotated. The mount sheet conveyance roller 122 rotates in synchronization with the platen roller 120.

A peeler 130 is configured by the peeler unit 110 (mounting sheet pressing roller 123), the peeler roller 121, and the mounting sheet conveying roller 122. When the peeler unit 110 is opened, the mount pressing roller 123 mounted on the peeler unit 110 is separated from the mount conveying roller 122, so that the mount discharge path 118b connected to the mount discharge port 111 is opened. Similarly, when the opening / closing lid 104 is opened, the platen roller 120 mounted on the lid 104 is separated from the thermal head 119, and the conveyance path 118 is opened. When the roll paper 115 is replaced, a new roll paper 115 is put in this state, and the paper 114A is pulled out therefrom.
The opening / closing lid 104 and the peeler unit 110 are closed in this order. As a result, a paper set state in which the paper 114A passes between the thermal head 119 and the platen roller 120 and is drawn out to the label discharge port 112 or the mount discharge port 111 is formed.

(Peeler configuration)
Next, the configuration of the peeler 130 will be described in detail with reference to FIGS. FIGS. 13 and 14 are cross-sectional views showing the peeler before and at the time of label issuance when the operation state is set to perform the label peeling operation, and FIG. 15 is a retracted state in which the peeling operation is not performed. It is sectional drawing which shows the peeler set to (2).

First, the peeler unit 110 attached to the printer main body side includes a unit frame 131 that can be swung up and down around a support shaft 116 on the printer main body side, and a mount pressing roller 12.
3 is supported by the unit frame 131 in a state in which it can pivot up and down.

The first press position 135A on the upper side shown in FIG. 13 and FIG.
When the peeler unit 110 is closed in the state of being set to 1, the mount presser roller 123 is moved to the paper 1
14A is sandwiched and set to the mount holding position 123A pressed from the upper side of the mount conveying roller 122. In this state, the mount 114b is removed from the mount discharge port 1 via the peeler roller 121.
The peeler 130 is in a state where it can be transported toward the head 11 and can perform a label peeling operation.
This is an operable state.

On the other hand, the mount pressing roller support frame 135 is moved to the lower second turning position 135 shown in FIG.
When the peeler unit 110 is closed in the state of being set to B, the mount pressing roller 123 does not hit the mount conveying roller 122 but is set to the retracted position 123B retracted to the front side position. In this state, the mount 114b is removed from the mount discharge port 111 via the peeler roller 121.
The peeler 130 is in a retracted state where the label peeling operation is not performed.

Therefore, in the state where the peeler unit 110 is opened as shown in FIG. 11, the mount pressing roller support frame 135 is set in a state of being swung from the first turning position 135A to the second turning position 135B, and in this state, the peeler unit 110 is set. Is closed, the peeler 130 can be switched to the retracted state.

Next, details of the structure of each part will be described. First, the unit frame 13 of the peeler unit 110.
1 includes a connecting portion 132 extending in the printer width direction and left and right arm portions 133 and 134 extending in the front-rear direction of the printer at both ends of the connecting portion 132. Shaft holes 133a and 134a are formed at the front ends of the arm portions 133 and 134, and a support shaft 116 on the printer main body side is inserted therethrough in a rotatable state. The unit frame is centered on the support shaft 116. 131 can be opened and closed.

The mount pressing roller support frame 135 attached to the unit frame 131 includes left and right turning arms 136 and 137 extending in the front-rear direction of the printer. A connecting portion 138 is bridged in the width direction of the printer at the front end portion of these printers, and a base sheet pressing roller 123 is bridged in a rotatable state below the connecting portion 138. In addition, the swivel arm 136,
The front end portion of the printer 137 is attached to the left and right arm portions 133 and 134 of the unit frame 131 so as to be turnable in the vertical direction.

A label detection lever 139 that can turn around the rotation shaft 123 a of the mount pressing roller 123 is attached to the mount pressing roller support frame 135. As shown in FIG. 13, the label detection lever 139 is held at a first position 139 </ b> A that is disposed so as to straddle the label discharge port 112 in the front-rear direction of the printer. This label detection lever 13
9 is pushed up by the label 114c discharged toward the label discharge port 112, and can turn as shown in FIG.

Here, a photocoupler 140 that functions as a lever detection unit is attached to the connection portion 132 of the unit frame 131. The detection area 140 a of the photocoupler 140 is located at the center of rotation of the mount pressing roller support frame 135. The tip 139a of the label detection lever 139
Is located in the detection region 140a. Label 1 from which the label detection lever 139 is discharged
When turned by being pushed by 14c, the tip end portion 139a is disengaged from the detection region 140a of the photocoupler 140. When the label detection lever 139 is no longer detected, the photocoupler 1
From 40, a label detection signal indicating that the label 114c remains in the label discharge port 112 is output.

(Label issuing operation)
The operation of the peeler 130 having this configuration will be described. As an operation mode for issuing labels, there are a label peeling issue mode for issuing labels one by one and a label continuous issuing mode for issuing labels continuously without peeling. In either case, the roll paper storage unit 115
The roll paper 114 is loaded with a roll of paper 114A having a structure in which a label 114c of a predetermined length is attached to a long mount 114b at a predetermined interval.

In the label peeling issue mode in which the labels 114c are issued one by one, the paper 114A is shown in FIG.
As shown in FIG. 3, the paper is passed over the peeler roller 121, passed between the mount transport roller 122 and the mount presser roller 123, and then set to be pulled out from the mount discharge port 111. When the sheet 114A is transported in this state, the mount 114b is discharged from the mount discharge port 111. In the peeler roller 121, each label 114c attached to the mount 114b depends on the strength (rigidity) of the waist. Mount 114 in the peeler roller 121
Without being bent together with b, it is peeled off from the mount surface and heads toward the upper label discharge port 112.

As shown in FIG. 14, the label 114 c is discharged while pushing up the label detection lever 139 disposed at the first position 139 </ b> A across the label discharge port 112. As a result, from the detection area 140a of the photocoupler 140, the leading end 139a of the label detection lever 139 is obtained.
And the photocoupler 140 outputs a label detection signal indicating that the label 114c remains in the label discharge port. As a result, it is detected that one label has been issued from the label discharge port 112. Thereafter, the conveyance of the sheet 114A is stopped, and the label 11
Wait until 4c is removed. When the label 114c is removed by the operator, the label detection lever 139 returns again to the first position 139A in FIG. 13, and the output of the photocoupler 140 stops. That is, it is detected that the label 114c is removed and no label remains in the label discharge port 112. Thereafter, the conveyance and printing operation (label issuing operation) of the paper 114A is resumed. In this way, labels are created and issued one by one.

Here, the label detection lever 139 of the present example includes the label discharge port 112 and the mount discharge path 118.
The turning center is located between b. Accordingly, the mount 11
The label 114c after being peeled off from 4b does not fall down to the mount 114b and stick to the mount 114b again. That is, after the tip of the label 114c peeled off from the mount 114b comes into contact with the label detection lever 139, the label detection lever 139 turns in the label discharge direction, and the label 114c slides along the label contact surface 139b. Then, it is guided in the label discharge direction.

In particular, the peeler roller 1 is provided on the label contact surface 139b of the label detection lever 139 of this example.
A step 139 c is formed at a position directly above 21. The leading end of the label 114c that is about to fall down to the mount 114b hits the step 139c, and the fall to the mount 114b is surely prevented, and the label detection lever 139 turns and moves toward the label discharge port 112. Guided.

It is desirable that the label contact surface 139b has a surface shape that contacts the label 114c in a point contact or line contact state so that the label 114c slides smoothly along the label contact surface 139b. . If the sliding resistance of the label 114c sliding on the label abutting surface 139b is set to be small in the label discharging direction and large in the opposite direction, the label 114c is moved along the label abutting surface 139b. It is more desirable because it can guide quickly in the label discharge direction.

Next, an operation for continuously issuing the label 114c will be described. In this case, as shown in FIG. 15, the mount pressing roller support frame 135 is turned from the first turning 135 </ b> A to the second turning 135 </ b> B, and the paper 114 </ b> A is set to be pulled out from the label discharge port 112. A label detection lever 139 is attached to a rotating shaft 123a of the mount pressing roller 123 supported by the mount pressing roller support frame 135 so as to be rotatable. Therefore, when the mount pressing roller support frame 135 is turned to the second position 135B, the label detection lever 139 also does not interfere with the label 114c discharged from the label discharge port 112, as shown in FIG.
Evacuated to the state.

As described above, the detection area 140a of the label detection lever 139 by the photocoupler 140.
Is located at the center of rotation of the mount pressure roller support frame 135. Accordingly, even when the mount pressing roller support frame 135 is turned to the second turning position 135B, the photocoupler 140 is also turned on.
In this detection region 140a, the state where the tip 139a of the label detection lever 139 remains positioned is formed. Therefore, the label detection signal is not output from the photocoupler 140, and the output state that the label 114c does not remain at the label discharge port 112 is always maintained. In other words, the label detection operation is disabled.

Accordingly, the printing operation for the label 114c on the mount 114b is continuously performed without interrupting the conveyance of the sheet 114A, and the created label 114c is continuously labeled with being attached to the mount 114b. It is discharged from the discharge port 112. Therefore, the operation control mode when issuing labels continuously may be exactly the same as the operation control mode when issuing labels one by one without doing anything special, and operation mode switching operation, etc. Is also unnecessary.

As described above, in the printer with a peeler according to the present embodiment, the peeler for peeling the printed label from the long mount, the label discharge port for discharging the peeled label, and the label discharge A label detection lever which is held by a predetermined urging force so as to stop at a first position arranged across the outlet, and which is pushed by the discharged label and is pivotable in the label discharge direction; and the label detection And a lever detector that detects that the lever is in the first position.

In this configuration, when the label is discharged from the label discharge port, the label detection lever is pushed by the label and pivots in the label discharge direction, and the label detection lever is released from the first position. Since the label detection lever is pushed by the label while the label remains in the label discharge port, the label detection lever cannot return to the first position across the label discharge port. While the lever detection unit detects that the label detection lever is out of the first position, the subsequent label issuing operation is not started.

Thus, it is detected whether the label remains in the label discharge port by mechanical engagement with the label remaining in the label discharge port. In addition, since the lever detection unit for detecting the position of the label detection lever may be disposed inside the printer, even if an optical sensor such as a photocoupler is used as the detection unit, it may be affected by external light. Absent. Therefore, unlike the case of using an optical sensor arranged at the label discharge port, it is possible to accurately detect whether or not the label remains at the label discharge port without being erroneously influenced by outside light or the like. .

In addition, when the label detection lever is retracted to the second position where it does not hit the ejected label during continuous issuance of labels, a state in which the label detection lever is always detected by the lever detection unit is formed. An output indicating that no label remains at the label discharge port is always obtained. Therefore, as in the case of issuing labels one by one, it is possible to perform continuous label issuing operation by operation control based on the output of the lever detection unit, and there is no need to perform different operation control without doing anything special Also, the operation mode switching operation is unnecessary.
