DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming an image on a label of a label sheet having a large number of labels stuck on the mount, and then bending the mount of the label sheet at a steep angle to at least the front edge of the label. The present invention relates to a label printer which peels off a label.

[0002]

2. Description of the Related Art In a conventional label printer, for example, a label sheet in which a number of labels are adhered on a backing made of continuous paper is conveyed by a sheet conveying mechanism, and the label of the conveyed label sheet is imaged by a printing mechanism. After the formation, the mount is bent at a sharp angle by a peeling member to peel off the front edge of the label and to project from the label issuing port.

[0003]

In the above-described label printer, since the label whose front half is peeled off from the backing paper is automatically issued, the operation of attaching the label to the product can be easily performed. . Here, when a label sheet is set in a label printer as described above, for example, a label sheet having a label attached to a backing sheet is inserted between a line head of a printing mechanism and a platen roller, and the printing mechanism is operated. The backing sheet of the inserted label sheet is wound around a peeling member and inserted between pinch rollers for backing up the backing sheet.

Here, for example, in order to improve the portability of the label printer, it is conceivable to abolish the backing mechanism of the backing sheet and to sequentially discharge the backing sheet. However, when such a label printer is implemented, it is assumed that the backing paper sequentially discharged when setting the label sheet on the label printer hinders the operation. For this reason, there is a demand for a proposal of a means for easily executing the setting of the label sheet in a label printer which sequentially discharges the sheet without winding the sheet.

[0005]

A printing mechanism is provided for conveying a label sheet having a large number of labels attached to a backing made of continuous paper to form an image on the label, and the printing mechanism forms an image on the label. In a label printer provided with a peeling member for peeling at least the front edge of the label by bending the backing of the peeled label sheet at a steep angle, the backing paper discharge opening from which the backing paper whose label has been peeled off by the peeling member is discharged to the main body housing. And a label issuing port from which the label is discharged is formed. The lower edge of the printer cover, which freely opens and closes the printing mechanism and the peeling member, is rotatable on the upper edge of the mount outlet of the main body housing. A stopper mechanism is provided for pivotally supporting and restricting the opening position of the printer cover, which is opened by rotating downward from above, substantially in parallel with the direction in which the backing paper is discharged.

[0006]

According to the present invention, a backing sheet discharge port for discharging the backing sheet from which the label has been peeled by the peeling member is formed in the main body housing, and a label issuing port for discharging the label is formed so that the printing mechanism and the peeling member can be freely opened and closed. The lower edge of the printer cover is rotatably supported on the upper edge of the backing paper outlet of the main body housing, and the opening position of the printer cover, which is opened by turning downward from above, is approximately parallel to the backing paper discharge direction. Is provided, the discharge direction of the backing sheet sequentially discharged when setting the label sheet is guided by the printer cover.

[0007]

An embodiment of the present invention will be described with reference to the drawings.
First, as illustrated in FIG. 2, the label printer 1 which is the label printer of the present invention is formed in a portable and portable type, and the portable handy terminal 2 is also portable.
In combination with the optical data transfer system 3.

The label printer 1 is provided with a shoulder belt 4 having an adjustable length above both sides and a belt handle 6 on one side. Here, the main body housing of the label printer 1 is composed of a front cover 7 and a rear cover 8 joined from front and rear.
Printer cover 9 and interface cover 1
0 is connected in parallel. Here, a horizontally long mounting sheet discharge port 11 is formed between the front cover 7 and the lower edge of the printer cover 9, and a horizontally long label issuing port is formed on the front face of the printer cover 9 which is pivotally supported to be openable and closable. 12 are formed. Further, in the optical data transfer system 3, an information input hole 13 is formed on the front surface of the interface cover 10, and an annular support ring 14 is attached to the outer peripheral portion.

On the other hand, the handy terminal 2 which is also a barcode scanner has an information output projection 16 protruding from a tip end of a sharp portion 15a formed at one end of a housing 15, and a keyboard 17 is provided on the upper surface of the housing 15. The display 18 is arranged. The information output projection 16 of the handy terminal 2 is formed in a tapered shape with a step like connecting a cone to a cylinder, and an optical lens is attached to a pointed end.

Further, in the label printer 1, as shown in FIG. 1, a sheet storage section 22 for exchangeably storing a label sheet 21 having a label 20 stuck on an elongated mount 19 is formed in the printer body. A seat cover 23 that covers the seat storage portion 22 so as to be openable and closable is attached to the rear cover 8. Further, the printing mechanism 24, which is openably and closably covered by the printer cover 9, has a structure in which a line head 25, which is swingable here, is pressed and held on a platen roller 26 which is a sheet conveying mechanism. A separating member 27 for separating the label 20 by bending the mount 19 of the label sheet 21 at an acute angle is provided between these members. A pinch roller 28 for transporting the backing sheet 19 of the label sheet 21 is in contact with the platen roller 26 from below. The pinch roller 28 protrudes from a distal end of an arm 29 that supports the pinch roller 28 in a swingable manner. The manual knob 30 is connected to the printer cover 9.
Is located on the back side.

In the label printer 1, a paper cutter 31 is formed at the lower edge of the printer cover 9 forming the upper edge of the mount paper outlet 11, and both sides of the paper cutter 31 are attached to the mount paper discharge port. A stopper mechanism (not shown) for regulating the opening position of the printer cover 9 by contacting the edge of the outlet 11 is formed.

In such a configuration, in the optical data transfer system 3, for example, when commodity data is input to the handy terminal 2 by operating the keyboard 17, reading a bar code, or the like, the data is transferred to a RAM (Random Access).
(Temporary Memory). Therefore, the information output projection 16 of the handy terminal 2 storing the product data is connected to the information input hole 13 of the label printer 1.
When the keyboard 17 is operated by inserting the product data into the device, the product data is output from the information output protrusion 16 of the handy terminal 2 as an optical signal. Therefore, this optical signal is photoelectrically converted by a light receiving element (not shown) in the information input hole 13 of the label printer 1, and is also temporarily stored in an internal memory such as a RAM, for example, to issue a bar code label or to store product information. Will be used for tasks such as management of
