Abstract

A rail configured to guide a carriage is provided. The rail includes a first unit and a second unit; and a coupling mechanism. The coupling mechanism is configured to couple a first target member, which is a coupling target that is either a first support or a first rack, to a second target member, which is a coupling target that is a second support or a second rack. The coupling mechanism includes a coupling member; a first fixing member; and a second fixing member. The first fixing member is configured to position the first target member and the coupling member, and the second fixing member is configured to adjust relative positions of the second target member and the coupling member, and is configured to fix the second target member and the coupling member at adjusted relative positions.

Dependent claims

A rail configured to guide a carriage traveling in a predetermined travel direction, the rail comprising:

a first unit and a second unit each extending in the travel direction, and lined up in series in the travel direction;
and
a coupling mechanism configured to couple the first unit and the second unit to each other, and
wherein:
the first unit and the second unit each comprise:
a support;
a rack fixed to the support and configured to engage with a pinion of the carriage;
and
a rail body fixed to the support while being parallel to the rack, and configured to guide travel of the carriage,
a width direction is a direction orthogonal to the travel direction when viewed in an up-down direction, a first side in the width direction is one side in the width direction, a second side in the width direction is another side in the width direction, a first support is the support of the first unit, a second support is the support of the second unit, a first rack is the rack of the first unit, and a second rack is the rack of the second unit,
the coupling mechanism is configured to couple a first target member, which is a coupling target that is either the first support or the first rack, to a second target member, which is a coupling target that is either the second support or the second rack,
the coupling mechanism comprises:
a coupling member having a reference abutment face configured to abut against both a first reference face, which is a reference face of the first target member facing the first widthwise side, and a second reference face, which is a reference face of the second target member facing the first side in the width direction;
a first fixing member configured to fix the coupling member to the first target member;
and
a second fixing member configured to fix the coupling member to the second target member,
the first fixing member is attachable to and detachable from at least either the coupling member or the first target member, and is configured to position the first target member and the coupling member by being attached, and
the second fixing member is configured to adjust relative positions of the second target member and the coupling member, and is configured to fix the second target member and the coupling member at adjusted relative positions.
