Electronic apparatus
An electronic apparatus is to be electrically connected to another electronic apparatus. The electronic apparatus comprises a first contact, a memory and a processor. The first contact is a contact whose conductivity varies corresponding to a connection state with another electronic apparatus. The processor is coupled to the memory. The processor is configured to perform acquiring a value indicating the conductivity of the first contact when bringing the first contact into a contact state with another electronic apparatus and determining, based on the acquired value indicating the conductivity and a predetermined reference value, whether a connection between the electronic apparatus and another electronic apparatus is sufficient.

a first contact with conductivity varying corresponding to a connection state with the first electronic apparatus;
a sensor configured to detect the first electronic apparatus approximate to the sensor;
a memory; and
a processor coupled to the memory and the processor configured to perform:
restricting providing electricity to the first contact while the sensor does not detect the first electronic apparatus approximate to the sensor;
starting providing electricity to the first contact when the sensor detects the first electronic apparatus approximate to the sensor;
acquiring a value indicating the conductivity of the first contact when providing the electricity to the first contact; and
determining, based on the acquired value indicating the conductivity and a predetermined reference value, whether a connection between the electronic apparatus and the first electronic apparatus is sufficient,
wherein the first contact includes a spring,
the value indicating the conductivity is a force applied to the spring, and
the processor determines that the connection between the electronic apparatus and the first electronic apparatus is sufficient when the force applied to the spring is larger than a predetermined load.
