<p>PURPOSE:To provide an intermittent controller between a bus and an electronic equipment capable of unnecessitating special works and saving power. CONSTITUTION:A system including the bus is provided with the bus 1 capable of transferring data, a first electronic equipment 3a connected with the bus 1 and a second electronic equipment 3b. An intermittent controller 5 between the bus and the electronic equipment is applied to this system. The intermittent controller 5 between the bus and the electronic equipment is composed of a bus cut-off/operation stoppage circuit 51 and a control circuit 52. The bus cut-off/operation stoppage circuit 51 operates by the command from the outside and forms a bus cut-off signal and an operation stoppage signal. The control circuit 52 electrically off the bus 1 and the first electronic equipment 3a or the second electronic equipment 3b by the bus cut-off signal from the bus cut-off/operation stoppage circuit 51 and stops the operation of a first electronic equipment 3a or a second electronic equipment 3b by the operation stoppage signal.</p> |
