and a calculation means which calculates, as the number of evacuees in the evacuation shelter, the number of the terminals which have transmitted the signals. ## Claims ### Claim 1 A calculation device comprising: a communicator configured to transmit a response request to a terminal in an evacuation shelter and receive, from the terminal responding to the response request, a signal according to an operation by a user of the terminal; and a calculator configured to calculate, as a number of evacuees in the evacuation shelter, a number of the terminals transmitting the signal, wherein the communicator transmits the response request a plurality of times, and wherein, when the terminal transmitting the signal does not respond to the response request, the calculator calculates a number of evacuees without including the terminal in the number of evacuees. ### Claim 2 (depends on 1) The calculation device according to claim 1 wherein the communicator receives, from the terminal transmitting the signal, a request for connection to an external network, and relays communication between the terminal and the external network. ### Claim 3 (depends on 1) The calculation device according to claim 1, wherein the calculator calculates, as a number of evacuee candidates, a number of the terminals responding to the response request. ### Claim 4 (depends on 3) A calculation system comprising: a setter; and a plurality of the calculation devices according to claim 3, wherein, in each of the calculation devices, the communicator transmits the response request to the terminal in the evacuation shelter, the terminal being different for each of the calculation devices, and the calculator calculates, as the number of evacuee candidates for the evacuation shelter, a number of the terminals responding to the response request, and outputs the number of evacuee candidates to the setter, and the setter sets a quantity of supplies to be allotted to the evacuation shelter, according to the number of evacuee candidates being output from the calculator. ### Claim 5 (depends on 3) A calculation system comprising: a setter; and a plurality of the calculation devices according to claim 3, wherein in each of the calculation devices, the communicator transmits the response request to the terminal in the evacuation shelter, the terminal being different for each of the calculation devices, and receives a signal, from the terminal responding to the response request, a signal according to an operation by a user of the terminal, and the calculator calculates, as the number of evacuees for the evacuation shelter, a number of the terminals transmitting the signal, and outputs the number of evacuees to the setter, and the setter sets a quantity of supplies to be allotted to the evacuation shelter, according to the number of evacuees being output from the calculator. ### Claim 6 A calculation method comprising: transmitting a response request a plurality of times to a terminal in an evacuation shelter; receiving, from the terminal responding to the response request, a signal according to an operation by a user of the terminal; and calculating, as a number of evacuees in the evacuation shelter, a number of the terminals transmitting the signal, wherein, when the terminal transmitting the signal does not respond to the response request, a number of evacuees is calculated without including the terminal in the number of evacuees. ### Claim 7 A non-transitory storage medium storing a program causing an information processing device to execute: processing of transmitting a response request a plurality of times to a terminal in an evacuation shelter; processing of receiving, from the terminal responding to the response request, a signal according to an operation by a user of the terminal; and processing of calculating, as a number of evacuees in the evacuation shelter, a number of the terminals transmitting the signal, wherein, when the terminal transmitting the signal does not respond to the response request, a number of evacuees is calculated without including the terminal in the number of evacuees. ### Claim 8 (depends on 1) The calculation device according to claim 1, wherein the communicator receives, from the terminal transmitting the signal, a request for connection to an external network, and relays communication between the terminal and the external network. ### Claim 9 (depends on 1) The calculation device according to claim 1, wherein the calculator calculates, as a number of evacuee candidates, a number of the terminals responding to the response request. ### Claim 10 (depends on 2) The calculation device according to claim 2, wherein the calculator calculates, as a number of evacuee candidates, a number of the terminals responding to the response request.
