## Abstract

A winding device includes a winding shaft that rotates and winds a print medium conveyed from a printing device having a conveyance roller that conveys the print medium, a gear, and a motor driving the conveyance roller and the gear. The winding device also includes a power transfer mechanism to connect to the gear and transfer power to the motor, and a lever disposed between the winding shaft and the conveyance roller in a conveyance path in a configuration in which the winding device is connected to the printing device. The lever may be moved between a first position in which the print medium bends and a second position in which the print medium bends at a shallower angle than at the first position.

## Claims

### Claim 1

A winding device attachable to a printing device having a conveyance roller configured to convey a print medium from a printing device and a motor, the winding device comprising;
a winding shaft configured to rotate and wind the print medium conveyed from the printing device;
a power transfer mechanism configured to connect to the gear and transfer power from the motor to the winding shaft; and
a lever disposed between the winding shaft and the conveyance roller in a conveyance path when the winding device is connected to the printing device,
wherein the lever is configured to move between a first position in which the print medium bends at a first angle and a second position in which the print medium bends at a second angle that is larger than the first angle.

### Claim 2 (depends on 1)

The winding device described in claim 1, wherein:
the power transfer mechanism includes an input gear that is connected to the gear, the input gear being configured to move relative to the gear.

### Claim 3 (depends on 2)

The winding device described in claim 2, wherein:
the input gear is inserted in an input unit insertion recess of the printing device; and
an input support unit rockably supports the input gear.

### Claim 4 (depends on 1)

The winding device described in claim 1, wherein:
the first position is lower than the second position.

### Claim 5 (depends on 1)

The winding device described in claim 1, further comprising:
an elastic member that the lever contacts when the lever is at or near the second position.

### Claim 6 (depends on 1)

The winding device described in claim 1, wherein:
the lever comprises a roller.

### Claim 7 (depends on 6)

The winding device described in claim 6, wherein:
the roller includes a plurality of roller segments distributed in an axial direction.

### Claim 8 (depends on 6)

The winding device described in claim 6, wherein:
the lever further comprises a roller lever that supports the lever and is configured to rotate on a pivot point.

### Claim 9 (depends on 1)

The winding device described in claim 1, wherein:
the power transfer mechanism includes a torque limiter.
