Title:
DATA RELAY APPARATUS
Document Type and Number:
Japanese Patent JP2023111115
Kind Code:
A
Abstract:
To suppress noises and crosstalks by reducing a wiring length of a pulse transformer and a communication module.SOLUTION: A data relay apparatus comprises: an optical communication part 200 that performs an optical communication with a portable terminal 100; a communication module 202 that performs a communication with an external device 102 that is connected with a wire via an external connector 204 on the basis of a result of the optical communication with the portable terminal 100; a pulse transformer 205 that is connected between the external connector 204 and the communication module 202; and a control substrate 209 on which the communication module 202 and the pulse transformer 205 are mounted. The communication module 202 is arranged on one surface of the control substrate 209, and the pulse transformer 205 is arranged at a position overlapped with the communication module 202 in view of a thickness direction of the control substrate 209 in the other surface of the control substrate 209.SELECTED DRAWING: Figure 4
