## Abstract

This disclosure discloses a printer comprising a roll storage part, a feeder, a printing head, a pair of guide members, a guide driving mechanism, a cover, a pressing roller, and a recessed part. The printing head is configured to perform desired printing on the print-receiving tape fed by a feeder. The pair of guide members are configured to determine a width-direction position of the print-receiving tape while sandwiching the stored roll. The guide driving mechanism is configured to make the pair of guide members move close to and away from each other by advancing and retreating in tandem in a width direction of the roll. The pressing roller is configured to contact the print-receiving tape near a feed-out position. The recessed part is configured to house at least a part of the pressing roller, provided to each position of the pair of guide members.

## Claims

### Claim 1

A printer comprising:
a roll storage part configured to store a roll that winds a print-receiving tape;
a feeder configured to feed said print-receiving tape fed out from said roll stored in said roll storage part;
a printing head configured to perform desired printing on said print-receiving tape fed by said feeder;
a pair of guide members configured to determine a width-direction position of said print-receiving tape fed out from said roll while sandwiching the stored roll, provided on said roll storage part;
a guide driving mechanism configured to make said pair of guide members move close to and away from each other by advancing and retreating in tandem in a width direction of said roll with respect to a reference position;
a cover that covers said roll storage part;
a pressing roller configured to contact said print-receiving tape fed out from said roll near a feed-out position, the pressing roller rotatably provided on said cover; and
a recessed part configured to house at least a part of said pressing roller, the recessed part provided to each position of said pair of guide members corresponding to said pressing roller.

### Claim 2 (depends on 1)

The printer according to claim 1, further comprising:
a support member that extends from said cover toward an area near said feed-out position and rotatably supports said pressing roller,
wherein said recessed part is configured to house both at least a part of said support member and at least a part of said pressing roller.

### Claim 3 (depends on 1)

The printer according to claim 1, wherein:
said recessed part is provided on said guide member so as to open on a cover side.

### Claim 4 (depends on 1)

The printer according to claim 1, wherein:
said guide driving mechanism is configured so that said pair of guide members are adjustable to selectively sandwich a plurality of different widths of tape rolls; and
a roller width of said pressing roller is smaller than a space between outer ends of said pair of guide members when a roll with a minimum tape width of said plurality of widths is sandwiched therebetween.

### Claim 5 (depends on 1)

The printer according to claim 1, wherein:
each guide member of said pair of guide members further comprises a guide protruding part that protrudes along said width direction, on a downstream side of said recessed part in a feed-out direction.

### Claim 6 (depends on 5)

The printer according to claim 5, wherein:
said guide protruding part is configured to contact and guide, from above an end part of said print-receiving tape in said width direction, the print-receiving tape fed out from said roll, when said cover is opened.

### Claim 7 (depends on 6)

The printer according to claim 6, wherein:
said guide protruding part is configured to not contact said print-receiving tape fed out from said roll, when said cover is closed.

### Claim 8 (depends on 5)

The printer according to claim 5, wherein:
said guide protruding part is configured to contact said print-receiving tape fed out from said roll and to be driven to rotate.

### Claim 9 (depends on 1)

The printer according to claim 1, further comprising:
a guide rail configured to be inserted through said pair of guide members and guide said pair of guide members,
wherein said recessed part is disposed above said guide rail.
