Abstract
An open/close counting device to be attached to one of a first die and a second die which constitute a die, the die being opened by relatively moving the first die and the second die, the open/close counting device counting the number of open/close times of the die. The open/close counting device includes an open/close detecting section provided so as to face a target face of the other of the first die and the second die and to detect relative displacement of the target face along a die moving direction in non-contact condition, and includes an output section to output the open/close times counted based on detection of open/close by the open/close detecting section.
