In the following examples, the label printer according to the present invention will be described in detail based on the examples. The present invention is not limited to the detailed description of the examples, and can be appropriately modified without departing from the gist of the present invention.

FIG. 1 is a schematic cross-sectional view of the label printer according to the present invention at the time of continuous issuance. In FIG. 1, the label printer 1 is mainly composed of a main body 2 and a cover 3 that rotates around a pivot axis 4. Further, in the roll paper 5, the label 7 is temporarily attached to the strip-shaped mount 6 at regular intervals and wound, and the label paper storage portion on the upstream side of the main body 2 with respect to the transport direction A (not shown). It is loaded in. When the roll paper 5 is loaded into the label paper storage portion, the cover 3 is rotated to open the entire upper surface of the main body 2. Here, continuous issuance refers to an issuance method in which the roll paper 5 printed on the label 7 and temporarily attached to the mount 6 is conveyed.

The platen roller 9 is arranged so as to be in contact with the thermal head 10 on the downstream side in the transport direction A from the label paper storage portion, the roll paper 5 is sandwiched between the platen roller 9 and the thermal head 10, and the platen roller gear described later. The platen roller 9 is driven by 9a to convey the roll paper 5 in the conveying direction A. Further, the print data is printed on the label 7 by applying it to a heat generating element (not shown) provided on the thermal head 10. In this way, the platen roller 9 and the thermal head 10 form a printing portion.

A pressing roller 8 stretched between the label paper storage portion and the printing portion so that the roll paper 5 does not loosen presses the upper surface of the label 7. Further, a positioning sensor 18 is provided below the mount 6 on the upstream side of the printing portion, and a black thin strip-shaped positioning mark (not shown) is formed in the width direction at a fixed position on the back surface of the mount 6. In this case, a reflective sensor is used as the positioning sensor 18 for detecting the positioning mark, and a transmissive sensor is used as the positioning sensor 18 for detecting the gap between the front and rear label 7 mounts 6. .. The output from these positioning sensors 18 is detected to control the printing start position in the printing unit.

A peeling portion 16 is provided on the downstream side of the printing portion to turn the mount 6 at an acute angle and peel the label 7 from the mount 6. Further, a cutter 17 composed of a fixed blade 17a and a movable blade 17b is housed in the cutter device 20 on the downstream side of the peeling portion 16, and the movable blade 17b is driven by a drive motor (not shown) to move up and down. .. In the case of continuous issuance, when the label 7 at the tip is printed by the printing portion, the intermediate portion of the gap between the label 7 at the tip and the mount 6 of the next label 7 is cut by being sandwiched between the fixed blade 17a and the movable blade 17b. It is conveyed so as to come to the cut portion, and the movable blade 17b is raised and cut. On the other hand, in the case of peeling issuance, which will be described later, when printed, a part of the label 7 is transported to the position where the label 7 is temporarily attached to the peeling portion 16, so that the cutter is controlled so as not to operate. The label 7 and the mount 6 peeled off by the peeling portion 16 are turned downward and conveyed.

A battery storage unit 19 for mounting a battery (not shown) is provided on the downstream side (rear end side) of the bottom of the main body 2, and the battery can be taken in and out from the rear end side. In addition to the case where such a type of label printer 1 is driven by a household power source and used as a desktop type, the label printer 1 is placed on a moving cart and brought to a site such as a store to price a product by battery drive. It may also be used as a discount.

FIG. 2 is a schematic cross-sectional view when switching from continuous printing to peeling printing of the label printer according to the present invention. In FIG. 2, the same parts as those in FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted. On the left and right (width direction) of the bottom surface side of the cutter device 20, the bottom surface of the U-shaped slide frame 22 provided integrally is extended so as to be the same as the bottom surface of the cutter device 20, and the side frame of the main body 2 The upper surface of the battery housing portion 19 is slid while sliding on the left and right (width direction) guide pins 21 protruding inward. Further, as shown in FIG. 3 , a discharge port 23 is provided in the space between the rear surface (the surface that abuts the main body 2) and the bottom surface of the cutter device 20, and when the rear surface of the cutter device 20 abuts the main body 2, the peeling portion 16 The mount 6 that is peeled off and transported is discharged from the main body 2 to the outside of the device of the label printer 1 via the discharge port 23.

Next, the procedure for switching from the continuous issuance state to the peeling issuance state will be described in detail with reference to FIGS. 1 and 2. First, the locking portion (not shown) between the cutter device 20 and the main body 2 is released from the state of continuous issuance in FIG. 1, and the left and right (width direction) U-shaped slide frame 22 is left and right (width direction). ), The cutter device 20 is pulled out so as to slide on the upper surface of the battery housing portion 19 while sliding, and when the guide pin 21 reaches the stroke end of the slide frame 22, it rotates slightly counterclockwise. , A large space is formed between the main body 2 and the main body 2 to separate them.

Then, the locking portion of the peeling frame 24 rotatably provided as a rotation mechanism is released from the left and right (width direction) side frames of the main body 2, and the peeling frame 24 is rotated from the peeling portion 16. Only the mount 6 is pulled out and passed between the driven roller 12 and the driving roller 13 and passed between the cutter device 20 and the main body 2. This state is shown in FIG.

After the mount 6 peeled off by the peeling portion 16 is switched to the transport path for issuing the peeling as shown in FIG. 2, the peeling frame 24 is then rotated clockwise to peel off the driven roller 12. Is brought into contact with the drive roller 13 so as to sandwich the above, and is locked to the main body 2. Then, the upper surface of the battery housing portion 19 is slid while rotating the cutter device 20 clockwise and sliding on the left and right guide pins 21, and when the rear surface of the cutter device 20 comes into contact with the main body 2, the cutter device 20 is locked. The state in which the label at the tip is peeled off and issued is shown in FIG. In this way, the opening / closing mechanism is configured so that the cutter device 20 can be separated from the main body or brought into contact with the main body.

FIG. 3 is a schematic cross-sectional view of the label printer according to the present invention at the time of peeling and issuing. In FIG. 3, a platen roller gear 9a (indicated by a two-point chain line) is rotatably provided coaxially with the platen roller 9 and meshes with the main drive gear 11 (indicated by a two-point chain line). When the main drive gear 11 is driven clockwise by a drive motor (not shown), the platen roller gear 9a meshing with the main drive gear 11 is driven counterclockwise, and the platen roller 9 also rotates counterclockwise. Be made to.

Peeling frames 24 are rotatably provided on the left and right side frames of the main body 2, and a rotatably driven roller 12 and a turning roller 15 are rotatably pivotally attached to the left and right peeling frames 24. The driven roller 12 is provided so as to be in contact with the drive roller 13, and the peeling portion 16 sandwiches the peeled mount 6. Further, a drive roller gear 13a (indicated by a two-dot chain line) is rotatably provided coaxially with the drive roller 13, meshes with the main drive gear 11, and the main drive gear 11 is driven clockwise by the drive motor. Then, the meshing drive roller gear 13a is driven counterclockwise, the coaxial drive roller 13 also rotates counterclockwise, and the mount 6 sandwiched between the driven roller 12 and the drive roller 13 is conveyed downward. NS.

The turning roller 15 rotatably provides the conveyed roll paper 5 on the peeling frame 24 below the peeling portion 16 so that the backing paper 6 is bent at an acute angle so that the label 7 can be easily peeled from the mount 6 at the peeling portion 16. Has been done. Then, the mount 6 in which the peeled mount 6 is sandwiched between the driven roller 12 and the drive roller 13 is conveyed downward.

The mount 6 sandwiched between the driven roller 12 and the driving roller 13 and conveyed downward is discharged from the discharge port 23. Since the cutter device 20 is locked to the upper part of the main body 2 from the battery storage portion 19 so that the battery can be easily attached to and removed from the downstream side to the upstream side, the label printer 1 may be used on a desktop. Even if it is placed on a moving cart at the site and used, the peeled mount 6 is passed through the discharge port 23 of the label printer 1 by using the space corresponding to the height of the battery storage portion 19 below the cutter device 20. It can be easily discharged to the outside of the device.

As shown in FIG. 3, after the label 7 at the tip is printed by the printing portion, the roll paper 5 is conveyed to the position where a part of the label 7 temporarily attached remains on the peeling portion 16, and is peeled off by the peeling portion 16. The issuing method of transporting the backing sheet 6 downward is called peeling issuing. The label 7, which is partially attached to the peeling portion 16, is removed by the operator.

A peeling sensor 14 is provided on the downstream side of the cutter 17 to detect whether or not the label 7 with a part temporarily attached to the peeling portion 16 has been removed by an operator. When the label 7 partially attached is removed by the operator, the peeling sensor 14 detects that the label 7 is absent, and is controlled so that the next label is peeled and issued by the output signal.

When switching from the peeling issuance of FIG. 3 to the continuous issuance of FIG. 1, the work can be performed in the reverse procedure so far. In addition, the label printer 1 can perform continuous issuance and peeling issuance by switching between continuous issuance and peeling issuance, and also has a cutter function. Therefore, the standard machine is specially shipped as an option with a cutter specification. There is no need to use one standard machine.

In this embodiment, a case where the space formed between the bottom portion of the main body 2 and the rotating mechanism and the cutter device 20 is arranged as the battery storage portion 19, but the rear end side of the main body 2 and the cutter are described. The bottom of the main body 2 can be raised so that the backing sheet 6 peeled off from the device 20 is formed by a space that can be discharged.

In recent years, various types of label printers have been adopted in retail stores according to the purpose, but there is a tendency to concentrate on label printers with multiple functions due to maintenance costs and complicated management.
