Abstract

In a circuit board unit storing circuit boards in a plurality of columns and rows, mounting and demounting of the circuit boards are locked without increasing an external shape of a product compared to a conventional configuration. Substrates are provided that have cut-away portions and a lock structure of a circuit board unit includes a slide portion that is formed of a frame member having openings arranged in a grid shape into which the circuit boards are able to be inserted and that is slidably mounted on a circuit board insertion surface of a front mask, and projection portions that are provided in the slide portion and are fitted into the cut-away portions of the circuit boards stored in a case when the slide portion is slid in one direction.

First claim

1 . A lock structure of a circuit board unit in which circuit boards are detachably stored in a storage case,
wherein the circuit boards comprise cut-away portions, and wherein the lock structure of the circuit board unit comprises: a slide portion that is comprised of a frame member having openings arranged in a grid shape into which the circuit boards are insertable and that is slidably mounted on a circuit board insertion surface of the storage case; and projection portions that are provided in the slide portion and that are fitted into the cut-away portions of the circuit boards stored in the storage case when the slide portion is slid in one direction.

2 . The lock structure of a circuit board unit according to claim 1 , further comprising:
slide bars that are provided on both side surfaces of the slide portion in a direction perpendicular to a slide direction; case-side engaging portions that are provided in a center of the slide portion in the direction perpendicular to the slide direction; slide rails that are provided in the storage case and configured to slidably hold the slide bars; and slide-side engaging portions that are provided in the storage case and that are configured to engage with the case-side engagement portions.

3 . The lock structure of a circuit board unit according to claim 1 or 2 , further comprising:
lid portions that are provided in the openings of the slide portion and are able to be detached.

4 . The lock structure of a circuit board unit according to any one of claim 1 or 2 , further comprising:
a marker portion that is provided in the storage case and is viewable in a state in which the projection portions are disengaged from the cut-away portions of the circuit boards stored in the storage case.
