摘要 <p>PURPOSE:To prevent an internal component from being broken owing to the impression of an excessive external force as a main body is made thinner by detecting the application of the external force and generating an alarm. CONSTITUTION:External force detecting means 40-a-40-c are provided nearby a liquid crystal display 2 as a component which is the weakest to an external force. The liquid crystal display 2 deforms with the external force, output signals from the external force detecting means 40-a-40-c are amplified by the deformation quantity to detect the impression of the external force exceeding a certain value, and an alarm means is actuated with its signal to warn the abnormality so that the deformation does not become larger. Consequently, the abnormal external force can be detected before the breakage of the component, so the component never gets out of order and the reliability of the product is improved.</p>
