Information processing apparatus

An information processing apparatus comprising:

• a host system;
• a rectifying element configured to output a signal input to one end to the other end;
• and
• a socket configured to connect a peripheral device,
• wherein the host system is connected to the other end,
• the socket includes a first signal terminal to which a first signal is input from the peripheral device and a second signal terminal to which a second signal is input from the peripheral device in a case where the socket is connected to the peripheral device, and the first signal terminal is connected to the one end,
• the first signal has a first voltage higher than a reference potential,
• the second signal has a second voltage higher than the reference potential in a case where the first voltage is equal to or lower than an operation voltage of the host system, and has a second voltage having no significant difference from the reference potential in a case where the first voltage is higher than the operation voltage of the host system, and
• the information processing apparatus further includes a circuit configuration configured to bring a potential of the one end close to the reference potential in a case where the first voltage is higher than the operation voltage of the host system.
