TECHNICAL FIELD OF THE INVENTION
The present invention relates to a printing apparatus, and more particularly to a printing apparatus such as a thermal transfer printer that prints on a long print medium.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a thermal head type printing apparatus using an ink ribbon, which prints on a printing medium such as a long sheet or a label (die-cut label) that is removably attached to a long sheet at an equal interval ( Printers) are known. In such a printing apparatus, as a transporting means for transporting the print medium as described above, a transport means for nipping and transporting the print medium by a pair of pressure-contacted transport roller members is generally used.
[0003]
By the way, in a printing apparatus in which a printing medium is nipped and conveyed by such a pair of conveying roller members, when a trouble occurs during a printing operation or when the printing medium is exchanged, the printing medium has a pair of rollers. It was inconvenient to remove the print medium while being held between the members. For this reason, there is a recording apparatus configured to release the pressure contact between a pair of conveying roller members as necessary (for example, see Patent Document 1).
[0004]
Further, there has been proposed a printer device configured to release the pressure contact only on one side in the longitudinal direction of the roller when releasing the pressure contact between the pair of transport roller members as described above (for example, see Patent Document 2).
[0005]

JP-A-11-322145 [0006]
[Problems to be solved by the invention]
However, in the above-mentioned Patent Document 1, when releasing the pressure contact between the pair of transport roller members, it is necessary to release the pressure contact over the entire area in the roller longitudinal direction. For this reason, when the pressure contact releasing means is provided at both ends in the roller longitudinal direction of the pair of conveying roller members, or when the pressure contact releasing means is provided only on one side in the roller longitudinal direction, the pressure contact releasing by the pressure contact releasing means on one side is performed. Since a mechanism for acting on the entire region in the longitudinal direction of the roller is required, the structure becomes complicated and the cost increases.
[0007]
Further, in Patent Document 2, since the release of the pressure contact between the pair of transport roller members is linked to the change in the transport direction of the print medium, the rapid release of the pressure contact is performed when some trouble occurs during the printing operation. However, the direction in which the pressure contact is performed and the direction in which the pressure contact is released are both limited to only one direction.
[0008]
