Abstract

A medium transporting apparatus is used for transporting a label web including a carrier web and labels adhered thereto. A platen roller transports the label web in a transport path. A pressure roller is disposed downstream of the separating member with respect to the transport path, and causes the carrier web to be kinked. The pressure roller urges the carrier web against the platen roller. A support member is mounted on a cover and rotatably supports the pressure roller. The cover is pivoted between an open position and a closed. Immediately after the cover has moved to the closed position, the pressure roller contacts the platen roller and then slides by a predetermined amount on the circumferential surface of the platen roller in a direction away from the separating member. Thus, the carrier web sandwiched between the pressure and platen rollers becomes taut.

Dependent claims

A medium transporting apparatus, comprising:

a transporting member configured to transport a medium in a transport path;
a separating member via which the medium is transported by the transporting member in the transport path, the separating member being pivotally supported relative to a chassis of the medium transporting apparatus, the separating member including an edge member that abuts the medium to cause the medium to kink, and a support that supports the edge member and is pivotally supported about a rotational axis of the transporting member;
a pressure roller disposed downstream of the separating member with respect to the transport path, the pressure roller urging the medium, which has passed the separating member, against the transporting member;
and
a support member configured to rotatably support the pressure roller thereon, the support member being movable between a first position where the pressure roller is out of contact engagement with the transporting member and a second position where the pressure roller is in contact engagement with the transporting member via the medium, the separating member being configured to pivot in a direction away from the pressure roller due to movement of the support member from the first position to the second position, the support member including a cam configured to, when the support member moves from the first position to the second position, push said support to cause the edge member to pivot about the rotational axis of the transporting member in the direction away from the pressure roller.

A medium transporting apparatus, comprising:

a transporting member configured to transport a medium in a transport path;
a separating member via which the medium is transported by the transporting member in the transport path, the separating member being pivotally supported relative to a chassis of the medium transporting apparatus;
a pressure roller disposed downstream of the separating member with respect to the transport path, the pressure roller urging the medium, which has passed the separating member, against the transporting member, the pressure roller including a shaft with a first flat surface;
and
a support member configured to rotatably support the pressure roller thereon, the support member being movable between a first position where the pressure roller is out of contact engagement with the transporting member and a second position where the pressure roller is in contact engagement with the transporting member via the medium, the separating member being configured to pivot in a direction away from the pressure roller due to movement of the support member from the first position to the second position,
wherein the support member includes:
a portion having a hole receiving the shaft and a second flat surface defining a part of the hole, the second flat surface preventing the shaft from rotating when abutting the first flat surface;
and
an urging member configured to urge the shaft against the second flat surface so that the first flat surface abuts the second flat surface;
and
wherein the support member is configured to prevent the pressure roller from rotating when the separating member pivots in the direction away from the pressure roller, and allow the pressure roller to rotate in the second position;
wherein when the support member is in the second position, the transporting member presses the pressure roller against the urging of the urging member so that the first flat surface is out of abutting engagement with the second flat surface.

and
an urging member configured to urge the shaft against the second flat surface so that the first flat surface abuts the second flat surface;
wherein the support member is configured to,
when moving toward the second position while pressing the pressure roller against the transporting member via the medium, prevent the pressure roller from rotating to cause the pressure roller to slide by a predetermined amount on the transporting member in a direction away from the separating member, and
allow the pressure roller to rotate in the second position;
and
wherein when the support member is in the second position, the transporting member presses the pressure roller against the urging of the urging member so that the first flat surface is out of abutting engagement with the second flat surface.
