## Abstract

A main body case is provided with an opening and closing lid supported in an openable and closable manner by a spindle at one end portion thereof as well as slidably attached in a direction orthogonal to a length direction of the spindle; a pair of unlocking knobs slidably arranged along a front surface of the opening and closing lid; and a locking portion formed on a main body case side that puts the opening and closing lid in a locked state by locking a step portion on a free end portion side of the opening and closing lid by sliding operating the opening and closing lid in one direction in a state where the opening and closing lid is closed.

## Claims

### Claim 1

A locking device comprising:
a lid supported to be openable and closable by a spindle at one end portion thereof and slidably attached to one side surface of a main body case in a direction orthogonal to a length direction of the spindle;
a pair of unlocking knobs slidably arranged along a front surface of the lid; and
a locking portion formed on a main body case side and configured to set the lid in a locked state by locking a free end portion side of the lid by sliding the lid in one direction in a state where the lid is closed, wherein
by sliding the pair of unlocking knobs in the locked state of the lid, a sliding operation of the lid in another direction is enabled to unlock the lid,
on a back side of each of the pair of unlocking knobs in a state where the lid is closed, a knob guide provided with a prism-shaped protrusion is arranged on the main body case side,
a projection pin is formed so as to project from a back surface of each of the pair of unlocking knobs, and a side surface of the projection pin of each of the pair of unlocking knobs is configured to position along any one of two orthogonal side surfaces of the prism-shaped protrusion formed in each of the knob guides, and
the sliding operation of the lid is enabled when each of the projection pins is positioned along a first side surface of the prism-shaped protrusion, and the sliding operation is disabled when each of the projection pins is positioned along a second side surface of the prism-shaped protrusion.

### Claim 2 (depends on 1)

The locking device according to claim 1, wherein
in a case where the lid is closed, a tip portion of each of the projection pins projecting on each of the back surfaces of the pair of the unlocking knobs abuts a tip portion of the prism-shaped protrusion provided on each of the knob guides, and
a tilted surface where the projection pin of the unlocking knob is dropped along the first side surface of the prism-shaped protrusion is formed in the tip portion of the prism-shaped protrusion provided on each of the knob guides.
