Shock detecting apparatus and image forming apparatus comprises shock detecting apparatus
First Claim
1. A shock detecting apparatus comprising:
- a sensor which detects a shock received by an apparatus that is provided with the shock detecting apparatus;
a first memory which stores a first threshold value for detecting reception of a shock that cannot guarantee the function quality of the apparatus, but can enable operation of the apparatus;
a second memory which stores a second threshold value larger than the first threshold value for detecting reception of a shock that disables operation of the apparatus;
a third memory which stores shock detection information concerning a shock;
a control unit which compares the magnitude of a shock with the first and second threshold values when the sensor detects the shock, and controls to store the shock detection information concerning the shock in the third memory according to the comparison result; and
a battery which supplies power to the sensor and control unit even if power is not supplied from the power supply unit of the apparatus.
