## Abstract

A jam prevention mechanism includes a used tape guide with a guide surface along which a used tape fed out from a tape feeder is guided in a guide direction following a longitudinal direction of the used tape. A pressing member presses, against the guide surface, the used tape guided along the guide surface. A support member removably supports the pressing member.

## Claims

### Claim 1

A jam prevention mechanism for a used tape fed out from a tape feeder, the jam prevention mechanism comprising:
a used tape guide having a guide surface along which the used tape is guided in a guide direction following a longitudinal direction of the used tape;
a pressing member that presses, against the guide surface, the used tape guided along the guide surface; and
a support member that removably supports the pressing member.

### Claim 2 (depends on 1)

The jam prevention mechanism according to claim 1, further comprising a cutter disposed downstream of and adjacent to the used tape guide in the guide direction to cut the used tape guided along the guide surface,
wherein the pressing member presses the used tape at a position near the cutter.

### Claim 3 (depends on 1)

The jam prevention mechanism according to claim 1, wherein the used tape guide also functions as the support member.

### Claim 4 (depends on 3)

The jam prevention mechanism according to claim 3, wherein the used tape guide includes a based surface portion with the guide surface, and an auxiliary surface portion with an opposite surface to the guide surface, and
the pressing member is removably supported by the auxiliary surface portion.

### Claim 5 (depends on 1)

The jam prevention mechanism according to claim 1, wherein the support member includes a plate-like edge portion extending toward an upstream side in the guide direction, the pressing member includes an insertion and removal section which pinches the edge portion in a direction of a thickness thereof, and the pressing member is supported by the support member by moving the insertion and removal section closer to the edge portion from the upstream side such that the edge portion is inserted into the insertion and removal section, whereas the pressing member is removed from the support member by pulling out the insertion and removal section from the edge portion toward the upstream side.

### Claim 6 (depends on 5)

The jam prevention mechanism according to claim 5, wherein the edge portion of the support member is shaped to be bent in a middle portion of the edge portion in the guide direction.

### Claim 7 (depends on 5)

The jam prevention mechanism according to claim 5, wherein the pressing member includes a band-like main body portion extending in the guide direction, and the insertion and removal section is provided at one longitudinal end of the main body portion, and the main body portion presses the used tape guided along the guide surface.

### Claim 8 (depends on 7)

The jam prevention mechanism according to claim 7, wherein the pressing member is a band-like plate spring such that the insertion and removal section thereof is a fold-back portion obtained by folding back one longitudinal end of the plate spring, and the main body portion thereof is formed of a remaining portion of the plate spring, and the main body portion when flexed comes into contact with the used tape so as to press the used tape using a resilient force resulting from the flexure of the main body portion.

### Claim 9 (depends on 7)

The jam prevention mechanism according to claim 7, wherein the used tape guide includes the guide surface inclined with respect to a vertical direction, and
the main body portion of the pressing member is swingably connected to the insertion and removal section, and the main body portion presses the used tape guided along the guide surface under a weight of the main body portion.

### Claim 10 (depends on 1)

The jam prevention mechanism according to claim 1, wherein the pressing member includes a guide section that guides the used tape fed out from the tape feeder toward a position which is on the guide surface and at which the used tape is pressed by the pressing member.
