Claims

[Claim for Utility Model Registration] In a parallel signal transmission device in which a driver that transmits data and a receiver that receives data are connected by a parallel bus, it is detected that the bus that transmits data on the parallel bus is clamped. A clamp detecting means, a clamp talker for transmitting the position of the clamped pit to the receiving side, a selector for switching the signal to be transmitted by the clamped bit to a spare bus, and a spare bus driver for transmitting the output of this selector to the receiving side. a transmitting device equipped with the above; a spare bus receiver that receives the signal sent out by the spare bus driver; a clamp listener that receives the signal output from the clamp talker; A parallel signal transmission device comprising: a receiving device equipped with a selector for switching to a signal received by the spare bus receiver.
