Abstract

A controller unit includes: a base unit having a slot; a module that includes a printed circuit board and that is mounted on the base unit; a pair of male and female connectors, one being included in the base unit and the other being included in the module; and a turning support that allows the module to be turned with respect to the base unit. A pair of a recess and a projection are provided to prevent wrong attachment. The base unit has one of the recess and the projection and the module has the other. The positions of the recess and the projection vary depending on the type of module.

First claim

What is claimed is:

1. A controller unit, comprising:
a base unit having a slot;
a module that includes a printed circuit board and that is mounted in the slot of the base unit;
a pair of male and female connectors, one being included in the base unit and the other being included in the module in order to electrically connect the base unit to the module; and
a turning support configuration of a fitting type that allows the module to be turned with respect to the base unit in order to join the pair of connectors together by turning of the module with respect to the base unit; wherein
the base unit includes a projection and the module includes a plurality of recesses such that the projection engages with a recess of the plurality of recesses before the pair of connectors are connected together,
the recess and the projection are located at positions separated from positions of the pair of connectors in the base unit and the module, and a distance between the positions of the pair of connectors and the positions of the recess and the projection varies depending on a type of combination of the modules that cannot be wrongly joined to the slots,
the module includes a casing and the plurality of recesses are a plurality of holes in the casing, and
the printed circuit board is mounted in the casing and an edge of the printed circuit board includes a recessed shape at a position corresponding to a position of one hole of the plurality of holes in the casing.

2. The controller unit according to claim 1 , wherein
each of the recess and the projection is located between a position of the turning support configuration and the position of the connector.

3. The controller unit according to claim 1 , wherein
a positional relationship between the recess and the projection to be fitted together in a combination that allows the projection to be fitted in the recess and a positional relationship between the pair of male and female connectors to be fitted together are such that, if the module that is going to be attached to the slot is not a right module for that slot, offset contact between the edge of the printed circuit board and the projection occurs before the pair of male and female connectors contact each other.

4. The controller unit according to claim 1 , wherein
the number of the plurality of holes that are formed in the casing of the module is the same as the number of types of combination of the modules that can be wrongly joined to the slots, and the recessed shape that is formed in the edge of the printed circuit board is formed only for one of the holes.

5. The controller unit according to claim 1 , wherein
an opening of the recessed shape has a greater width than an inner part of the recessed shape.

6. The controller unit according to claim 1 , wherein
in terms of a distance from the turning support configuration, the pair of connectors are located at the same position regardless of a type of the module.

7. The controller unit according to claim 1 , wherein the projection fits in the recessed shape of the printed circuit board when the module is mounted in the slot of the base unit.

8. The controller unit according to claim 1 , wherein the edge of the printed circuit board is configured to contact the projection before the module is mounted in the slot of the base unit at positions corresponding to the other holes of the plurality of holes in the casing.
