Description

  The present invention relates to a stationary contactless communication terminal.

  Currently, non-contact communication terminals that use electronic money or credit cards as a reading target and read by non-contact communication using electromagnetic waves are provided. Especially, in stores and offices, they are placed on a mounting surface such as a desk. A stationary type is widely used. This type of stationary non-contact communication terminal is often kept near a specific place for a certain period of time, such as being permanently installed near a cash register of a store, for example, and is taken away by a third party other than the administrator. Therefore, a structure capable of preventing such removal and theft is required.

JP 2008-217186 A

  In order to prevent the stationary non-contact communication terminal from being taken away, the terminal is connected to an object that is difficult to move (for example, a desk existing at the place where the terminal is installed) in a state that is difficult to remove. A method is conceivable. For example, an engagement hole or the like is provided in the case of the terminal, and the case and the wire are connected through the hole, and the wire is connected to a fixed object such as a desk so that the wire is not removed. If locked, only the administrator who can unlock can move the contactless communication terminal, and the security can be improved.

  However, in a structure in which a hole is simply formed in the case and a connection component (security component such as a wire) is passed through this hole, the shape and configuration of the connection member that can be used to connect the terminal to a fixed object are limited. Therefore, there is a problem that the versatility is poor. For example, assuming a thin wire as a connection member and designing a small hole in consideration of space, strength, etc., when a user tries to use a thicker wire or replaces it with use It becomes impossible to cope when trying. In addition, even if the user wishes to fix security parts such as engaging members other than wires or locks directly to the case, it should be attached if the holes formed in the case do not have a shape corresponding to these security parts. I can't. Thus, simply forming a hole in the case has a low degree of freedom in selecting a security component and narrows the selection range of the security component. In addition, since it is difficult to select parts that are advantageous in terms of cost, there is a high possibility that the cost will be disadvantageous.

  Although not a stationary contactless communication terminal, in the field of notebook personal computers, a technology for connecting security wire slots as disclosed in Patent Document 1 is used. However, the technique of Patent Document 1 is not configured to solve the above problem. In other words, it is difficult to change the connection part connected to the notebook computer to a part other than a dedicated security wire slot (for example, a wire or a lock), and it cannot be denied that it has poor versatility. In addition, since the connecting parts that can be attached are limited to the dedicated security wire slot, it is not possible to cope with a change in which an inexpensive connecting part (wire, chain, etc.) is used, and the cost is very limited.

  The present invention has been made in order to solve the above-described problem, and in a stationary non-contact communication terminal that can be connected by a connecting component such as a wire and prevented from being taken away by a third party, the user can An object of the present invention is to provide a configuration with a high degree of freedom in selecting connection parts.
