Abstract

A film roll supporting device comprises a shaft body part, a shaft tip part, and a projection part. The shaft body part extends through a central hole of a film roll and having the film roll mounted thereon. The shaft tip part extends in an axis direction of a shaft from one end of the shaft body part on a side to be inserted into the central hole of the film roll. The projection part extends in a direction intersecting the axis direction of the shaft body part from the shaft tip part. The projection part abuts from below to a core of the film roll provisionally placed on the shaft tip part when the mounting of the film roll is performed. A cutout recessed in a direction intersecting the axis direction of the shaft body part is formed in the projection part.

Dependent claims

A film roll supporting device, comprising:

a cylindrical shaft body part, the shaft body part having a longitudinal central axis centered along a length of the shaft body part, the shaft body part having a first end and a second end that are spaced from one another along the longitudinal central axis;
a shaft tip part extending from the second end of the shaft body part along the longitudinal central axis, the shaft tip part including a clearance that has
a first end that extends downwardly from the longitudinal central axis proximate to the second end of the shaft body part, defining a bottom upper surface that lies below the longitudinal central axis, and
a second end that extends upwardly toward the longitudinal central axis, the second end of the clearance being spaced from the first end of the clearance,
the shaft tip part terminating in an upwardly-extending projection that arises from the second end of the clearance and extends above the longitudinal central axis, and
the upwardly-extending projection including a recessed cutout formed at an upper end thereof.

A film roll supporting device, comprising:

a base;
a cylindrical shaft body part supported generally horizontally on the base at a first end of the shaft body part, the shaft body part having a longitudinal central axis centered along a length of the shaft body part, and a second end that is spaced from the first end along the longitudinal central axis;
a shaft tip part extending from the second end of the shaft body part along the longitudinal central axis, the shaft tip part including a clearance that has
a first end that extends downwardly from the longitudinal central axis proximate to the second end of the shaft body part, defining a generally horizontal bottom upper surface that lies below the longitudinal central axis, and
a second end that extends upwardly toward the longitudinal central axis, the second end of the clearance spaced from the first end of the clearance,
the shaft tip part terminating in an upwardly-extending projection that arises from the second end of the clearance and extends above the longitudinal central axis, and
the upwardly-extending projection including a recessed cutout formed at an upper end thereof.
