A mounting device includes a case that has an insertion inlet for a mobile information terminal, a connector that establishes electrical connection to the mobile information terminal inserted in the insertion inlet, and an ejection mechanism that ejects the mobile information terminal after completion of processing through the connector. After the completion of the processing, by an action of the ejection mechanism, the mobile information terminal is popped up from the mounting device, and a user is understandably notified of the completion of the processing.
