Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label printer in which a label print start position is set and controlled by a feed amount from the time of label detection by a label sensor provided in the vicinity of a print section.

[0002]

2. Description of the Related Art In a conventional label printer, a label sensor is provided downstream of a peeling section which is close to a printing section, and the label sensor detects the leading edge of the label peeled from a mount sheet to feed the next label. Some printers set and manage the print start position. Such a label printer can maintain the printing position of each label accurately. However, such a label printer has the following drawbacks. First, as shown in FIG. 7, since the label 1 is held in the label printer in a state that it is usually wound in a roll shape, it has a curl. However, if the paper guide is provided on the upper surface side of the label 1 downstream of the peeling section, it becomes an obstacle when the label 1 is taken out, and if it is provided on the lower surface side of the label 1, the label 1 peeled from the mount will adhere. Therefore, the paper guide for the label 1 is not provided downstream of the peeling section. Therefore, the label 1 on the downstream side of the peeling portion is curved. Here, the strength of this bending is stronger in the label 1 located in the central portion than in the label 1 located on the outer peripheral portion of the roll. Therefore, the label 1 at the center is
The detection of the leading edge by the label sensor is delayed as compared with the label 1 on the outer peripheral portion of the roll. Therefore, when the label printer is used, the print state of FIG.
The print start position of the label 1 gradually shifts so that the print state shown in FIG. The label is issued in the direction indicated by the arrow in FIG.

Therefore, the setting of the print start position, specifically, the setting of the feed amount after the label sensor detects the label front end is appropriately changed. That is, as the bending of the label 1 becomes stronger and the detection of the leading end of the label 1 is delayed, the feeding amount can be set again to be smaller. Then, after changing the feed amount setting, operate the paper feed key or the test print key to check whether the print position is set correctly.
Issuing empty.

Further, when the size of the label is changed or the print content is changed, the feed amount from the time when the label leading edge, which is the print start position, is detected is initialized. For confirmation, the paper feed key and test print key are operated to issue a blank print. In other words, if you set the feed amount from the time when the label leading edge, which is the print start position, is set, the label issuance operation is performed to confirm the print misalignment regardless of the initial setting or resetting, and the blank label is issued. There is.

[0005]

When the feed amount from the time of detecting the label front end is set for positioning at the print start position, one label is issued as described above to check whether the print position is correct. Must. Therefore, it is troublesome that the label issuing operation must be performed every time the setting is performed.

[0006]

[Means for Solving the Problems] The print start position of a label is set and managed by the feed amount from the time of label detection by a label sensor which is provided in the vicinity of the print unit and detects a label peeled by a peeling unit. A label printer provided with a feed amount setting means for performing initial setting and resetting is provided with label issuing means for issuing one label based on the set value when the feed amount is set by the feed amount setting means. .

[0007]

When the feed amount setting means sets the feed amount from the time of label detection, which is the print start position of the label, the label issuing means issues one label based on the set value. For this reason, it is not necessary to perform a label issuing operation for issuing a label for checking print misalignment.

Next, FIG. 5 shows a setting screen 26 of this label printer with scale, in which a display column 27 for displaying various set values is fed from the time when the label front end, which is the print start position of the label 1, is detected. A column 28 is provided for displaying the set value of the quantity. Further, a key function display field 29 for displaying key functions on the keyboard 5 is provided, and by inputting the feed rate key indicated by the feed rate display 29a in the key function display field 29, the numeric keypad on the keyboard 5 can be operated. The input numerical value is internally input as the feed amount from the leading end, which is the print start position of the label 1.

Next, FIG. 1 is a flow chart showing the operation in the setting mode in which the above-mentioned setting screen 26 is displayed. First, the input of the ten keys is awaited (step 1). The input value is captured as various data. Here, it is judged whether or not the key input after inputting the ten keys is the feed amount key (step 2), and if it is the feed amount key, the value input by the ten key is set at the print start position of the label 1. It is written in the RAM 19 as a feed amount after a certain label front end is detected (step 3). The feed amount setting means is formed here. Then, the data is read (step 4), and the label 1 is programmed to be test-issued according to the data (step 5). The label issuing means is formed here. On the other hand, if it is not the input of the feed amount key, it is programmed to perform other processing according to the input key (step 6).

In such a structure, the label-equipped label printer prints the information edited on the basis of the measurement value of the balance 3 and the product data stored in advance in the printing unit 10, and prints the printed label. 1 is the peeling section 11 and the mount 1a
It is peeled from and is issued from the issuing port 2a. At this time,
The label printer unit 6 stops with the rear end of the label 1 slightly unpeeled, and the fact that the label 1 is taken out from the issuing port 2a indicates that the label installed between the peeling unit 11 and the issuing port 2a. When it is detected by the sensor 16, the next print issuance is started. The print start position of the label 1 is set and managed by the feed amount from the time when the leading edge of the label 1 is detected by the label sensor 16.

Here, in the label printer with scale of the present embodiment, in order to correct the deviation of the printing position due to the bending of the label 1, the operation mode is switched to the setting mode, the setting screen 26 is displayed and the printing is started. If the feed amount from the time when the leading edge of the label 1 is detected by the label sensor 16 which is the position is reset, that is, if a new feed amount is input using the ten keys and the feed amount key shown in the feed amount display 29a, the feed amount is changed. The label 1 for which printing has started in 1 is automatically test-issued for confirmation of print misalignment. Therefore, in the label printer with scale of the present embodiment, when the feed amount from the leading end of the label 1 which is the print start position is set, the print misalignment for confirming whether or not the correct print position has come out with the set value. Since it is not necessary to perform a label issuing operation for issuing the confirmation label 1, it is possible to contribute to an improvement in work efficiency, and it is possible to prevent forgetting to confirm the print misalignment. In this embodiment, the label 1 to be test-issued is blank in each column as shown in FIG. Further, in the present embodiment, the description has been given of the case where the feed amount is reset, but the print misalignment check is similarly performed when the feed amount is initially set when the label size is changed or the print content is changed. Label 1 for is test-issued.

[0015]

According to the present invention, the print start position of the label is set and managed by the feed amount from the time when the label is detected by the label sensor which is provided in the vicinity of the print part and detects the label peeled by the peeling part. A label printer provided with a feed amount setting means for performing initial setting and resetting is provided with label issuing means for issuing one label based on the set value when the feed amount is set by the feed amount setting means. Therefore, if you set the feed amount from the time when the label is detected, which is the print start position of the label, one label is issued by the label issuing means based on the setting. Since it is not necessary to perform the above, it is possible to contribute to the improvement of work efficiency, and it is possible to prevent forgetting to confirm the print misalignment.
