Abstract

PURPOSE:To accurately set the position of a label, by providing a mode change-over switch performing changing-over of a label issue mode and a feed length setting mode, and further providing a means converting the operating speed of a stepping motor at the time of the feed length setting mode, and a feed length counter. CONSTITUTION:A feed length setting mode or a label issue mode is checked by looking at the state of a mode change-over switch 15 at the time of operation and, at the time of the label issue mode, the usual issue of a label is performed. Next, at the time of the feed length setting mode, the exciting pattern of a stepping motor 9 is changed by an operating speed converting means 16 converting the operating speed of the motor 9 to rotate the motor 9 slowly as compared with a usual case. When a feed key 12 is pushed, the motor 9 rotates by one pulse to add a feed length to a feed length counter 20. In this state, the label 1 is fed and, when the front edge of the label 1 is not detected by a label detector 8, the feed length counter 20 is cleared and, after the front edge of the label 1 is detected, feed quantity is stored, and the feeding of the label 1 is stopped when the label 1 reaches a predetermined position. By this method, the position of the label can be accurately set visually, and a desired stop position can be determined.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a label printer having a function of feeding a label to a stop position by operating a feed key.

2. Description of the Related Art In general, a feed key is provided to position a label at a fixed stop position when setting label paper. That is, it is set to stop when the feed key is fed a certain amount from the reference position determined by the detector by one operation of the feed key. If printing is started from this stop position, printing can be performed accurately according to the format of the label.

The feed amount differs depending on the size and format of the label, but the conventional method of setting the feed amount is to store the feed amount corresponding to the label being used in memory, and then turn a dip switch. The amount of feed to be drawn is set by

Problems to be Solved by the Invention Since the feed amount of the label is only selected from a predetermined fixed length, the feed amount is a variable value, and there are a limited number of types. be. Therefore, there is a problem in that the types of labels that can be used are limited.

Means for Solving the Problems A mode changeover switch is provided for switching between a label issuing mode and a feed length setting mode, and operation speed conversion means slows down the operation speed of the step motor when the mode changeover switch is in the feed length setting mode. A feed length counter is provided to add and store the feed amount when the feed length is set.

Since the feed speed of the step motor is slow in the operational feed length setting mode, the label position can be set accurately by visual inspection.This allows the desired stop position to be determined, and the feed amount is added up by the feed length counter. Since the feed amount is set and stored, it can be used as a set feed amount as desired.

Example An embodiment of the present invention will be described based on the drawings.

First, a long mount 2 to which a large number of labels 1 are attached is wound into a roll and held in a label supply section 3.

The backing paper 2 pulled out from the label supply section 3 passes between the platen 4 and the thermal head 5 while holding the label 1, and the backing paper 2 is sharply bent at the position of the peeling plate 6, and the winding section It is wound at 7. The label 1 peeled off at the peeling plate 6 is detected by a label detector 8. Further, the platen 4 and the winding section 7
A step motor 9 is connected to.

Such a device is housed in a case 10, and a label issuing port 11 is formed on the front side of the case 10, and a feed key 12 and a mode changeover switch 15 are also provided.

Next, a CPU 14 is electrically provided, and this CPU
14, the feed key 12, the mode changeover switch 15, the label detector 8, and the operating speed conversion means 16 are connected. Further, the step motor 9 is connected to the CPU l4, and the PROM
17 and RAM 18 are connected.

The RAM 18 has a built-in memory 19 as a feed amount storage means and a feed length counter 20.

In such a configuration, during operation, the state of the mode selector switch 15 is checked to determine whether to select the feed length setting mode or the label issuing mode, and if the mode is the label issuing mode, normal label issuing is performed. In other words, the label 1 stops at the position where the leading edge of the label 1 has been fed a predetermined length stored in the memory 19 after being detected by the label detector 8. and pursuant to the issuance order,
Labels are issued one by one. Further, in this case, if the feed key 12 is operated, one label 1 is fed out without being printed and stopped at a fixed stop position. Therefore, it is useful to press the feed key 12 when setting paper.

Next, in the case of the feed length routine, the operating speed of the step motor 9, specifically, the excitation pattern of the step motor 9 is changed by the operating speed conversion means 16 so that the step motor 9 rotates slower than usual.

Then, when the feed key 12 is pressed, the step motor 9 rotates by one pulse, which is added to the feed length counter 20. If feeding is performed in this state and the leading edge of the label l is not detected by the label detector 8, the feed length counter 20 is cleared, and after the leading edge of the label l is detected, the feed amount is recorded as described above. and stops feeding when the specified position is reached.

Thereby, the operator can set the feed amount at the desired position, and by transferring the set contents of the feed length counter 20 to the memory 19, the arbitrary feed amount setting is completed.

Effects of the Invention As described above, the present invention includes a mode changeover switch for switching between the label issuing mode and the feed length setting mode,
When the mode changeover switch is in the feed length setting mode, an operating speed conversion means for slowing down the operating speed of the step motor and a feed length counter for adding and storing the feed amount at the time of setting the feed length are provided. Since the feed speed of the motor is slow, the label position can be set accurately even by visual inspection.This allows the desired stop position to be determined, and the feed amount is added and memorized by the feed length counter. , which can be used as an arbitrary setting feed amount.
