The mobile payment terminal device is connected to, for example, a vehicle-mounted communication device and can communicate with various devices via the vehicle-mounted communication device, as in the technique described in Patent Document 2 below.

Japanese Patent No. 5738008 JP, 2016-164503, A

In a moving environment (for example, in a taxi car), such a portable device may be connected to a control device (for example, a vehicle-mounted communication device) via a cable. At the tip of the cable, a connector that directly participates in the connection with the control device side is formed. In such a case, at the time of card payment, a portable device is handed over between a service provider (for example, a taxi driver) and a payer (for example, a taxi passenger). At this time, in a narrow moving environment, the cable may be pulled by something or the like, and the connection between the portable device and the connector of the cable may be disconnected. If this happens, the payment process will be hindered and the portable device may be damaged.

Such delivery of portable equipment is frequently performed during work in a mobile environment, and therefore some measures are required. For example, it may be possible to make the structure of the connector at the tip of the cable special. However, such a special structure cannot be adopted when adopting the shape of the connector conforming to the general-purpose standard (for example, USB) for compatibility with the control device.

Therefore, the present disclosure can prevent the detachment of the portable device even when the cable connected to the portable device is provided with a connector conforming to the general standard, and when the portable device is delivered or pulled by the movement. An object is to provide a possible connector structure and cable attachment structure.
