Further, the front surface 11a of the housing 11 is formed with a side portion 11a2 extending in the vertical direction toward the front surface 11a and a bottom portion 11a3 extending in the horizontal direction toward the front surface 11a, surrounding the recess 11a1 in an L shape. A connection terminal 15a included in the second interface 15 is attached to the side portion 11a2.

Accordingly, the portable terminal 6 is accommodated in the recess 11a1 by being inserted into the recess 11a1 of the housing 11 so that the portable terminal 6 is slid from right to left toward the side part 11a2 and the bottom part 11a3. Since the two interfaces 15 are connected, the work of attaching the mobile terminal 6 to the relay device 10 is facilitated.

Moreover, the housing 11 has a structure in which a triangular prism is placed horizontally.

Thereby, the three side surfaces of the triangular prism-shaped casing 11 become the front surface, the back surface, and the bottom surface, respectively, and when the relay device 10 is placed on a flat surface such as a table, the relay device 10 is not easily collapsed and high stability is ensured.

The relay device 10 according to the present invention is not limited to the above embodiment, and various modifications can be made. Hereinafter, main modifications will be described.

FIG. 5 is an external perspective view of the relay device 10a according to the first modification of the above embodiment, as viewed from the front surface 11a. As illustrated, in the relay device 10a, the connection terminal 15a included in the second interface 15 is attached to the side portion 11a2 so as to be slidable in the vertical direction toward the front surface 11a. In such a structure, for example, a guide for slidably holding the connection terminal 15a is provided on the surface of the side portion 11a2 on which the connection terminal 15a slides, and the inside of the housing 11 is connected by a cable such as a flexible printed circuit board.
