Printer

Abstract

This printer is provided with: a holding chamber for holding a roll in which a band-shaped backing sheet is wound in a rolled form; an opening / closing cover for opening and closing the holding chamber; and a switching unit configured so as to be movable between a first position when printing using a first print mode and a second position when printing using a second print mode to switch print modes. A portion of the opening / closing cover comes in contact with the switching unit so that the switching unit is displaced from the first position in the direction of the second position when the opening / closing cover moves from an open state to a closed state.

Description

technical field [0001] The present invention relates to a printer, for example, a printer that prints required information such as characters, symbols, graphics, or barcodes on a label temporarily attached to a backing paper, and has a peeling and issuing function that removes the label from the backing paper and issues it. label printer. Background technique [0002] A label printer is a printer in which the platen roller is rotated with one end of a continuous sheet of paper temporarily pasting a plurality of labels on a tape-shaped backing paper between the thermal head and the platen roller. Print the required information on each label while the continuous paper is being exported and fed in sheet form. [0003] In this label printer, there are two types of distribution methods, continuous distribution and peel-off distribution. The continuous distribution method is a method in which a label serving as a printing medium is temporarily pasted on the backing paper, and th...

Problems solved by technology

[0007] In the past, in printers capable of switching the issuing mode, when the switching unit (for example, the movable body 11 in Patent Document 1) was configured to be movable between the continuous issuing position and the peeling issuing position, sometimes the The switching unit moves appropriately from the stripped release position to the continuous release position

Failure to properly set the switching unit to the continuous release position can sometimes cause functional problems with the printer

[0008] For example, there may be functional problems such as that the opening and closing cover of the printer cannot be closed, or the backing paper cannot be cut by a cutter even if it can be closed.

In addition, when the switching unit is not properly set to the continuous release position, the presence or absence of the peeling roller cannot be accurately detected by the sensor because the peeling roller of the switching unit is not arranged at an appropriate position.

That is, in the case of adopting a system structure in which the sensor detects whether the peeling roller of the switching unit is at a predetermined position and determines which of the continuous issuing mode or the peeling issuing mode is used, there is a problem as follows: if it cannot be detected Whether the release roller is present or not, the printer's issue mode cannot be accurately determined
