The user can exchange the roll paper main body 16 by lifting the lid portion 14 upward by rotating the lid portion 14 about the shaft 19 as a rotation axis. At this time, when the lid portion 14 is lifted up to a predetermined height, the stopper function may work, and the lid portion 14 may be held in the raised state.

  The roll paper main body 16 is wound in a roll shape and stored in a roll paper holder (not shown) in the main body 18 of the printing terminal 1.

Below, each Example of the removal method of the paper dust by the printing terminal 1 mentioned above is described.
Example 1
In the method for removing paper dust by the printing terminal 1 described in the first embodiment, the air sucked by opening the lid portion 14 is discharged (sprayed) by closing the lid portion 14 with respect to the printing unit 10 and the platen 11. ), And blows away paper dust and dust adhering to the printing unit 10 and the platen 11.

  The printing terminal 1 according to the first embodiment is obtained by adding a removal mechanism to the configuration shown in FIG. The removal mechanism according to the first embodiment removes paper dust in conjunction with opening and closing of the lid 14 that constitutes a part of the printing terminal 1. That is, as will be described later, the removal mechanism sucks air when the lid portion 14 is opened, and discharges the air sucked when the lid portion 14 is closed to a predetermined place (for example, the printing unit 10 or the platen 11). . In addition, the removal mechanism of Example 2 and Example 3 which will be described later also removes paper dust in conjunction with opening and closing of the lid part 14 constituting a part of the printing terminal 1.

  As shown in FIG. 3A, the removal mechanism of the first embodiment includes a paper dust removing main body 30, an air suction path 31, an air discharge path 32, and a lid connection portion 33. In the printing terminal 1 according to the first embodiment, a part of the internal configuration of the printing terminal 1 illustrated in FIGS. 1 and 2 is omitted for easy understanding. The same applies to Example 2 and Example 3.

  The paper dust removing main body 30 has a bellows-like structure, for example, and is in a contracted state when the lid portion 14 is closed. When the user opens the lid portion 14 for replacing the roll paper main body 16 from this contracted state, the lid connecting portion 33 connecting the lid portion 14 and the paper dust removing main body 30 is lifted upward. When the lid connecting portion 33 is lifted upward, the paper dust removing body 30 is pulled upward accordingly.

  When the paper dust removing body 30 is pulled upward, the air sucked from the air suction port 34 is taken into the paper dust removing body 30 through the air suction path 31. When the lid part 14 is lifted and the stopper function of the lid part 14 is activated, the entry and exit of air between the paper dust removing body 30 and the air suction path 31 is blocked by a not-shown blocking plate or the like. By being blocked, the air taken into the paper dust removing body 30 does not leak outside through the air suction path 31.

  After the air is taken in, as shown in FIG. 3B, when the replacement of the roll paper body 16 is completed and the lid portion 14 is closed, the lid connecting portion 33 is interlocked with the downward movement of the lid portion 14. Be lowered. As the lid connecting portion 33 is lowered, the bellows-like paper dust removing main body 30 is pushed (pressed). By being pressed, the air taken into the paper dust removing main body 30 is discharged to the printing unit 10 and the platen 11 through the air discharge path 32 such as a tube. Paper dust and the like are very fine and tend to accumulate on the printing unit 10 and the platen 11 due to friction generated when the roll paper 17 is discharged. Therefore, air is discharged to the printing unit 10 and the platen 11.

  After the air is discharged, as shown in FIG. 3A, when the lid portion 14 is opened again, the blocking by the blocking plate between the paper dust removing body 30 and the air suction path 31 is released. As a result, air is taken into the paper dust removing body 30.

  As shown in FIG. 3C, the paper dust blown off by the discharge of air falls to the lower part of the enclosure surrounded by the partition plate 35. A paper dust tray 36 is arranged at the lower part of the enclosure, and the fallen paper dust is accumulated in the paper dust tray 36. With such a configuration, paper dust can be collected without scattering paper dust. When the paper powder tray 36 is filled with paper powder, the user slides the paper powder tray 36 and removes it from the main body 18 of the printing terminal 1, and discards the paper powder.

  Thereby, the user can clean the inside of the printing terminal 1 even by downsizing the printing terminal 1 without regularly cleaning the inside of the printing terminal 1 consciously. Further, since cleaning is performed in conjunction with an operation necessary for the operation of the printing terminal 1 such as roll paper replacement, malfunction of the printing terminal 1 and printing rubbing can be prevented. Further, in the printing terminal 1, since the cleaning member for removing paper dust or the like is not in direct contact with the print head or the platen 11, the life of the print head or the platen 11 can be extended.

(Example 2)
In the method for removing paper dust by the printing terminal 1 described in the second embodiment, the static electricity generating portion generates static electricity by opening the lid portion 14 for replacing the roll paper main body 16, and the static electricity generating portion Adhere dust. By adhering paper dust or the like, paper dust or the like adhering to the printing unit 10 or the platen 11 is removed.

  The printing terminal 1 according to the second embodiment is obtained by adding a removing mechanism to the configuration shown in FIG. As shown in FIG. 4, the removal mechanism of the second embodiment includes a lid detection unit 40 and a static electricity generation unit 41.

  The lid detection unit 40 detects opening and closing of the lid unit 14. The detection of opening / closing of the lid 14 is performed based on whether the main body 18 and the lid 14 are in contact with each other using, for example, a sensor. In this case, the lid 14 is closed if it is in contact, and the lid 14 is open if it is not in contact. Note that the method for detecting opening and closing of the lid 14 is not limited to this.

  The static electricity generator 41 is a device that generates static electricity, and generates static electricity when the lid detector 40 detects that the lid 14 has been opened. When static electricity is generated, paper dust or the like attached to the printing unit 10 or the platen 11 is attracted to and attached to the static electricity generation unit 41.

  Thereafter, when the replacement of the roll paper main body 16 is completed and the lid portion 14 is closed, the lid detection portion 40 detects that the lid portion 14 is closed, and accordingly, the static electricity generation portion 41 generates static electricity. Stop. By stopping the generation of static electricity, the paper dust or the like attached to the static electricity generation unit 41 is peeled off from the static electricity generation unit 41 and accumulated in the paper powder tray as in the first embodiment. When the paper dust tray is filled with paper dust, the user can discard the paper dust by sliding the paper powder tray and removing it from the main body 18 of the printing terminal 1.

  Thereby, the user can clean the inside of the printing terminal 1 even by downsizing the printing terminal 1 without regularly cleaning the inside of the printing terminal 1 consciously. Further, since cleaning is performed in conjunction with an operation necessary for the operation of the printing terminal 1 such as roll paper replacement, malfunction of the printing terminal 1 and printing rubbing can be prevented. Further, in the printing terminal 1, since the cleaning member for removing paper dust or the like is not in direct contact with the print head or the platen 11, the life of the print head or the platen 11 can be extended.

(Example 3)
The method for removing paper dust by the printing terminal 1 described in the third embodiment is a combination of the first and second embodiments. That is, air sucked by opening the lid part 14 is discharged (blowed) by closing the lid part 14 against the static electricity generating part to which paper dust or the like is adhered, and the paper dust adhered to the static electricity generating part is discharged. It is something that blows away.

  The printing terminal 1 according to the third embodiment is obtained by adding a removal mechanism to the configuration shown in FIG. As shown in FIG. 5A, the removal mechanism of the third embodiment includes a paper dust removing main body 50, an air suction path 51, an air discharge path 52, a lid connection part 53, a lid detection part 55, and a static electricity generation part 56. ing. The above-described configurations are the same as the functions of the configurations described in the first and second embodiments, and thus the description thereof is omitted.

  When the lid 14 is opened by replacing the roll paper main body 16 or the like, the air sucked in from the air suction port 54 passes through the air suction passage 51 by the upward movement of the paper dust removal main body 50, so that It is taken in. When the lid portion 14 is lifted and the stopper function is activated, the entry and exit of air between the paper dust removing body 50 and the air suction path 51 is blocked by a not-shown blocking plate or the like.

  At this time, the static electricity generation unit 56 generates static electricity based on the detection of opening of the lid by the lid detection unit 55. As a result, paper dust or the like adheres to the static electricity generation unit 56.

  After the air is taken in, as shown in FIG. 5B, when the replacement of the roll paper main body 16 is completed and the lid portion 14 is closed, the lid connecting portion 53 is lowered in conjunction with the downward movement of the lid portion 14. It is done. When the lid connecting portion 53 is lowered, the bellows-like paper dust removing main body 50 is pushed (pressed). By being pressed, the air taken into the paper dust removing main body 50 is discharged to the electrostatic charging unit through the air discharge path 52 such as a tube.

  In the second embodiment, it is assumed that the paper dust attached to the static electricity generation part is peeled off by stopping the generation of static electricity. However, immediately after the generation of static electricity is stopped, the adhered paper dust or the like may not be completely peeled off, so in Example 3, air is discharged to the static electricity generation part.

  The paper dust blown off by the air discharge accumulates in a paper dust tray provided in the printing terminal 1 as in the first and second embodiments. When the paper dust tray is filled with paper dust, the user can discard the paper dust by sliding the paper powder tray and removing it from the main body 18 of the printing terminal 1.

  Thereby, the user can clean the inside of the printing terminal 1 even by downsizing the printing terminal 1 without regularly cleaning the inside of the printing terminal 1 consciously. Further, since cleaning is performed in conjunction with an operation necessary for the operation of the printing terminal 1 such as roll paper replacement, malfunction of the printing terminal 1 and printing rubbing can be prevented. Further, in the printing terminal 1, since the cleaning member for removing paper dust or the like is not in direct contact with the print head or the platen 11, the life of the print head or the platen 11 can be extended.

  According to the printing terminal as described above, the user can clean the inside of the printing terminal without regularly cleaning it.

  Further, the above-described embodiment is not limited to the above-described embodiment, and various changes can be made without departing from the gist of the embodiment.
