Printer
Including a pair of support members sandwiching a roll-like print medium and a pair of swing members each including a holding pin for rotatably holding the print medium, mounted on the support member, capable of swing, respectively, and swinging in the direction where the pair of holding pins gets closer to each other by being brought into contact with the print medium, the swing member being mounted at a position biased to a taking-out direction side of the print medium in the support member and a length of the swing member in a swing radial direction being smaller than a length of the support member in a taking-in/out direction of the print medium.
1. A printer comprising:
first and second support members configured to sandwich a roll-like print medium;
a first swing member mounted on the first support member to swing around a first swing- member axis;
a second swing member mounted on the second support member to swing around a second swing-member axis;
the first swing member including a first holding pin configured to hold the print medium and swing around a first holding-pin fulcrum, the second swing member including a second holding pin configured to hold the print medium and swing around a second holding-pin fulcrum,
the first swing-member axis being different from the first holding-pin fulcrum and the second swing-member axis being different from the second holding-pin fulcrum.
2. A printer as set forth in claim 1 , wherein
each swing member of the first and second swing members is mounted in the respective support member at a position biased to a taking-out direction side of the print medium; and
a length of each swing member of the first and second swing members in a swing radial direction is smaller than a length of the respective support member in the taking-out direction.
3. A printer as set forth in claim 1 , wherein
each swing member of the first and second swing members is further configured to move in a linear direction.
4. A printer as set forth in claim 1 , wherein
each swing member of the first and second swing members has an initial contact point of the print medium below the respective swing-member axis.
5. A printer as set forth in claim 1 , wherein
the first swing member has an initial contact point of the print medium spaced from the first swing-member axis by a first distance and the first holding pin is spaced from the first swing-member axis by a second distance, the first distance being smaller than the second distance.
6. A printer as set forth in claim 1 , wherein
the first support member and the first swing member are configured to lock the first swing member.
