## Abstract

A recording apparatus includes a roll paper holder including a shaft portion which holds a roll paper such that the roll paper is capable of being fed, a temporal placement portion on which the roll paper is temporarily placed, and a roll paper lifting device which includes a placement portion on which the roll paper is placed, and lifts the roll paper to a height position of the shaft portion of the roll paper holder while an end of the roll paper in the temporarily placed state is placed on the placement portion so as to position a core port of a roll core of the roll paper and the shaft portion.

## Claims

### Claim 1

A recording apparatus comprising:
a roll paper holder including a shaft portion which holds a roll paper such that the roll paper is capable of being fed;
at least two rods which are arranged in parallel in a paper width direction;
a slide portion which is attached to the rods in a slidable manner and on which the roll paper is capable of being temporarily placed, wherein a space is formed between the roll paper in a state of being temporarily placed on the slide portion and the rods; and
a roll paper lifting device which includes a placement portion on which the roll paper is placed, and lifts the roll paper to a height position of the shaft portion of the roll paper holder while the roll paper in the temporarily placed state is placed on the placement portion so as to position a core port of a roll core of the roll paper and the shaft portion,
wherein the roll paper lifting device includes:
an elevating portion which has the placement portion and is capable of elevating in an up-down direction;
an operation lever which is rotationally movable about a fulcrum, and
a driving force transmission mechanism which converts rotational movement of the operation lever in an up-down direction to up-down movement of the elevating portion and transmits a driving force at a position of the operation lever, which is closer to the fulcrum.

### Claim 2 (depends on 1)

The recording apparatus according to claim 1,
wherein the placement portion of the roll paper lifting device is configured such that a position of a placement face of the placement portion when the elevating portion is located at a lower limit position in a range where the elevating portion moves up and down is identical to a position of a temporal placement face of the slide portion.

### Claim 3 (depends on 1)

The recording apparatus according to claim 1,
wherein the roll paper lifting device is configured such that:
a position of an upper face of the slide portion is located at a position lower than uppermost points of the rods, and
the placement portion is moved to the upper side from the position lower than the uppermost points of the rods with respect to the slide portion and lifts an end of the roll paper which is temporarily placed on the rods.

### Claim 4 (depends on 1)

The recording apparatus according to claim 1,
wherein the placement portion is configured so as to be swingable in accordance with an inclination posture of the roll paper.

### Claim 5 (depends on 1)

The recording apparatus according to claim 1,
wherein the roll paper holder is attached to a supporting main body of the roll paper holder through an adjusting portion which enables an angle of the shaft portion variable in accordance with an inclination posture of the roll paper.

### Claim 6 (depends on 1)

The recording apparatus according to claim 1,
wherein the elevating portion includes:
the placement portion; and
a rod member which is provided so as to extend to the lower side from the placement portion, and
the rod member is guided by a guiding portion provided on the slide portion so that the elevating portion is moved up and down in the vertical direction.
