JP-A-2005-271433 (paragraph numbers 0023 to 0024, FIGS. 4 and 5)

  However, in the roll paper magazine described in Patent Document 1, when the roll core that has been emptied after the roll paper is completely consumed is replaced with a new roll paper, or with another roll paper having a different paper width or surface quality, When replacing the roll paper magazine, it is necessary to open the case body of the roll paper magazine and simultaneously remove the roll paper from the sealed package in the delivered state and store it in the case body. Since there is an opportunity to come into direct contact with the surrounding atmosphere, especially the outer peripheral part and both side edges of the roll paper are affected by the humidity in the atmosphere and are deformed into waves, etc., or affected by excessive drying conditions. As a result, fine cracks may occur on the ink receiving surface. When it is deformed into waves or the like due to moisture, the recording medium conveyed under the print head snakes or the distance from the print head to the receiving surface becomes non-uniform, which affects the image quality in either case. there is a possibility. On the other hand, even when fine cracks occur on the ink receiving surface due to excessive drying, the ink absorption rate may be non-uniform and the image quality may be affected.

  Accordingly, an object of the present invention is to provide a roll paper magazine in which when the roll paper is replaced, the roll paper is not easily affected by the surrounding atmosphere such as humidity. It is to provide.

A first characteristic configuration of the present invention is a roll paper magazine in which roll paper as a recording medium for printing is stored so that it can be drawn out.
A roll paper cartridge that contains the roll paper in a sealed state is provided with a loading portion for loading the roll paper in a predetermined posture so that the roll paper can be pulled out from an opening formed in the roll paper cartridge. is there.

  Therefore, in the roll paper magazine according to the first characteristic configuration of the present invention, the user of the printer obtains a roll paper cartridge containing the roll paper in a sealed state, for example, from a roll paper manufacturer or the like, and rolls from the roll paper cartridge. If the roll paper cartridge is set in the roll paper magazine without taking out the paper, the leading edge of the roll paper is pulled out from the opening formed in the roll paper cartridge, and is pulled out from the opening in the roll paper magazine. Since it is introduced into the printing section and printing can be performed, there is no opportunity to expose the entire roll paper to the surrounding atmosphere, and the influence of the surrounding humidity and the like is difficult to reach the roll paper.

  In another feature of the present invention, the roll paper cartridge is provided with an access means on the side surface of the roll paper cartridge for rotating the roll paper core in at least the rewind direction by an operation from outside the roll paper magazine. There is in point.

  With this configuration, the access means provided on the side surface of the roll paper cartridge is connected to the output shaft of the rewinding motor provided in the printer, etc., so that the roll paper cartridge is once pulled out to the print unit. By rewinding the roll paper back into the roll paper cartridge at the end of printing or the like, it is possible to prevent the leading portion of the roll paper from being exposed to the atmosphere in the printer casing for a long period of time.

  Another feature of the present invention is that a humidity control material is disposed inside the roll paper cartridge.

  With this configuration, the inside of the roll paper cartridge is easily kept near the specific adjustment humidity of the humidity control material due to the action of the humidity control material, so that one roll paper cartridge remains in the roll paper magazine for a long period of time. Even so, the roll paper inside is less susceptible to the atmosphere in the printer housing.

A fourth characteristic configuration of the present invention is a roll paper magazine in which roll paper as a print recording medium is stored so as to be drawable.
An airtight container-like magazine body provided with an opening for pulling out the roll paper, a pressure roller for holding the leading end of the roll paper and pulling out from the opening, and further sealing the opening The sealing means and the rotation blocking means for blocking the rotation of the pressure roller are provided so as to be removable manually.

  Therefore, in the roll paper magazine according to the fourth characteristic configuration of the present invention, the printer user obtains the roll paper magazine in a form in which the roll paper is already stored in the magazine body from the roll paper manufacturer or the like, and the sealing means. The rotation prevention means is removed, and the pressure roller is manually rotated slightly until the tip of the roll paper protrudes from the opening, and then set in the printer, the printing operation can be started. There is no opportunity to expose the paper to the surrounding atmosphere, and the influence of the surrounding humidity or the like hardly reaches the roll paper.

  Another feature of the present invention is that the sealing means is made of an adhesive tape, and the sealing means made of the adhesive tape and the above are joined to each other.

  With this configuration, after obtaining the roll paper magazine containing the roll paper, the printer user can remove the rotation prevention means from the pressure roller and pull it away from the roll paper magazine to join the rotation prevention means. The adhesive tape is also peeled off automatically, making it easy to set up a roll paper magazine.

  According to another feature of the present invention, the side surface of the magazine body is provided with a rotation operation means for rotating the roll core of the roll paper at least in the rewinding direction by an operation from outside the roll paper magazine. Further, the rotation prevention means for preventing the rotation of the rotation operation means is provided so as to be removable manually.

  In this configuration, the roll paper once drawn from the roll paper magazine to the printing unit is connected by connecting the rotation operation means on the side surface of the magazine body to the output shaft of the rewinding motor provided in the printer. By rewinding the paper in the roll paper magazine at the end of printing or the like, it is possible to prevent the leading portion of the roll paper from being exposed to the atmosphere in the printer casing for a long period of time. Further, until the roll paper magazine is set in the printer for the first time, the rotation operation means and the pressure roller are prevented from rotating by the rotation prevention means. A part extending from the pressed roll paper part to the main body of the roll can be held in a relaxed state. Therefore, it becomes difficult for the roll paper to be cut by the pulling force from the pressure roller due to vibration or contraction during transportation or storage before use.

Another feature of the present invention is that a humidity control material is disposed inside the magazine body.
With this configuration, the inside of the roll paper magazine is easily kept near the specific adjustment humidity of the humidity control material due to the action of the humidity control material, so that one roll paper magazine remains set in the printer for a long period of time. However, the roll paper inside is less susceptible to the atmosphere in the printer casing.
