Description
この構成によれば、サーマルヘッドがプラテン軸と平行な姿勢を取るときに比べ、装着方向の手前側におけるサーマルヘッドの端部とプラテン軸との間隔が広くなる。したがって、カートリッジ装着部に第１テープカートリッジが装着される際に、装着方向の手前側におけるサーマルヘッドの端部に第１テープが引っ掛かることが抑制される。同様に、カートリッジ装着部に第２テープカートリッジが装着される際に、装着方向の手前側におけるサーマルヘッドの端部に第２テープが引っ掛かることが抑制される。 According to this configuration, the distance between the end of the thermal head and the platen shaft on the front side in the mounting direction becomes wider than when the thermal head takes a posture parallel to the platen shaft. Therefore, when the first tape cartridge is mounted on the cartridge mounting portion, it is possible to prevent the first tape from being caught on the end portion of the thermal head on the front side in the mounting direction. Similarly, when the second tape cartridge is mounted on the cartridge mounting portion, it is possible to prevent the second tape from being caught on the end portion of the thermal head on the front side in the mounting direction.
ここで、ヘッド加圧レバー２５は、ヘッド加圧リブ２６が第１係合位置から第２係合位置に回転する際に、ヘッド加圧リブ２６との係合部位を第１係合部位２５５から第２係合部位２５６へずらしながら、第１弾性位置から第２弾性位置へ回転する。このとき、ヘッド加圧レバー２５が第１係合領域２５３ａにおいてヘッド加圧リブ２６と係合する場合には、ヘッド加圧レバー２５は、ヘッド加圧リブ２６の単位回転量（例えば１°）に対して第１回転量で回転する。これに対し、ヘッド加圧レバー２５が第２係合領域２５３ｂにおいてヘッド加圧リブ２６と係合する場合には、ヘッド加圧レバー２５は、ヘッド加圧リブ２６の単位回転量に対して、第１回転量よりも小さい第２回転量で回転する。これは、上述したように、第２係合領域２５３ｂは、ヘッド加圧リブ２６から離れる方向に屈曲するようにして、第１係合領域２５３ａに連なっているためである。換言すれば、第２係合領域２５３ｂは、ヘッド加圧リブ２６のレバー側係合部２６３の移動軌跡に沿った形状に形成されている。このため、ヘッド加圧リブ２６の位置が、第２係合領域２５３ｂにおいてヘッド加圧レバー２５と係合する範囲で異なっても、ヘッド加圧レバー２５の位置はほとんど変わらない。
Here, the head pressurizing lever 25 changes the engaging portion with the head pressurizing rib 26 to the first engaging portion 255 when the head pressurizing rib 26 rotates from the first engaging position to the second engaging position. Rotates from the first elastic position to the second elastic position while shifting from to the second engagement portion 256. At this time, when the head pressurizing lever 25 engages with the head pressurizing rib 26 in the first engaging region 253a, the head pressurizing lever 25 has a unit rotation amount (for example, 1 °) of the head pressurizing rib 26. It rotates at the first rotation amount. On the other hand, when the head pressurizing lever 25 engages with the head pressurizing rib 26 in the second engaging region 253b, the head pressurizing lever 25 relatives to the unit rotation amount of the head pressurizing rib 26. It rotates at a second rotation amount smaller than the first rotation amount. This is because, as described above, the second engaging region 253b is connected to the first engaging region 253a so as to bend in the direction away from the head pressure rib 26. In other words, the second engaging region 253b is formed in a shape along the movement locus of the lever-side engaging portion 263 of the head pressure rib 26. Therefore, even if the position of the head pressurizing rib 26 is different in the range of engaging with the head pressurizing lever 25 in the second engaging region 253b, the position of the head pressurizing lever 25 is almost unchanged.
