Abstract

A blade driving device comprising: a driving member; one or more blade members that are caused to undergo sliding motion by the driving member; a blade supporting unit for supporting the blade member slidably; and a frame for containing the driving member and a portion of the blade supporting unit, wherein the blade supporting unit comprises a blade chamber for containing a blade member between opposing thin plate members, along with an insertion portion that has an opening and that protrudes from a frame, wherein the opposing thin plate members are integrated together at least the tip end of the insertion portion.

First claim

The invention claimed is:

1. A blade driving device, comprising:
a driving member;
one or more blade members that to undergo sliding motion by the driving member;
a blade supporting unit supporting the blade member slidably; and
a frame containing the driving member and a portion of the blade supporting unit, wherein:
the blade supporting unit comprises a blade chamber for containing a blade member between opposing thin plate members, along with an insertion portion that comprises an opening and that protrudes from a frame,
wherein the opposing thin plate members are integrated together at least at a tip end of the insertion portion.

2. The blade driving device as set forth in claim 1 , comprising:
an adhesive agent reservoir provided at a tip end portion of the insertion portion.

3. The blade driving device as set forth in claim 1 , wherein:
the opposing thin plate members are folded back at a tip end of the insertion portion.

4. The blade driving device as set forth in claim 1 , wherein:
the blade chamber is formed by bending an outer edge of the thin plate member.

5. The blade driving device as set forth in claim 1 , wherein:
the blade chamber is formed through half-etching the thin plate member.

6. The blade driving device as set forth in claim 1 , wherein:
the blade chamber is formed through a spacer that is disposed between the opposing thin plate members.

7. A camera provided with a blade driving device as set forth in claim 1 .

8. A mobile electronic device comprising a camera as set forth in claim 7 .
