Abstract
According to one embodiment, an impact detection device includes a mobile body having mass, a supporting section, and a holding section. The supporting section includes a fixed end to be fixed to a detection target object, includes an attachment section, to a halfway position in a longitudinal direction of which separated from the fixed end the mobile body is attached, and is deformed between the fixed end and the attachment section if acceleration exceeding a fixed threshold was caused in the mobile body by impact applied to the detection target object. The holding section holds the mobile body moved by the deformation of the supporting section in a moving destination.
Claims20
An impact detection device, comprising:
- a mobile body having mass;
- a supporting section including
- a fixed end to be fixed to a detection target object, and
- an attachment section to which the mobile body is attached at a position separated from the fixed end,
- the supporting section is deformed between the fixed end and the attachment section if acceleration exceeding a fixed threshold occurs in the mobile body by impact applied to the detection target object;
- and
- a holding section configured to hold the mobile body moved by the deformation of the supporting section while keeping a state in which the mobile body is moved.
A method of detecting a presence or an absence of an impact applied to a detection target object without using electric power, comprising:
- deforming a supporting section between a fixed end and an attachment section if acceleration exceeding a fixed threshold occurs in a mobile body by impact applied to a detection target object, an impact detection device comprising the mobile body, the supporting section including the fixed end to be fixed to the detection target object, and the attachment section to which the mobile body is attached at a position separated from the fixed end;
- and
- holding, via a holding section, the mobile body moved by the deformation of the supporting section while keeping a state in which the mobile body is moved.
A copying machine, comprising:
- an image forming device;
- a mobile body having mass;
- a supporting section including
- a fixed end to be fixed to the image forming device, and
- an attachment section to which the mobile body is attached at a position separated from the fixed end,
- the supporting section is deformed between the fixed end and the attachment section if acceleration exceeding a fixed threshold occurs in the mobile body by impact applied to the image forming device;
- and
- a holding section configured to hold the mobile body moved by the deformation of the supporting section while keeping a state in which the mobile body is moved.
