摘要： In a facsimile apparatus, an image to be transmitted is stored in a first memory and the stored image is transferred to and stored in a second memory, which is capable of being loaded to and unloaded from the facsimile apparatus. This processing is executed if certain conditions such as time are satisfied, and if the second memory has been loaded. After the transfer of the image data, the status of storage in each of the first and second memories is managed. In a case where the transmitted image that has been stored in the second memory is to be transferred to the first memory, a necessary condition is that the image stored in the loaded second memory coincide with the contents of the managed status of storage.

摘要： A data communication apparatus includes a data communication section for preforming data communication according to full duplex communication, a testing section for performing a communication test prior to the data communication, and a transmission controller for determining whether full duplex communication can be performed during a period of the communication test performed by the testing section. The testing section includes a backward signal generator, a backward signal detector, and a control signal analyzer. The backward signal generator and the backward signal detector may be replaced with an echo canceller.

摘要： A facsimile apparatus is disclosed in which a transmitting/receiving operation, as well as a copying operation, is performed by an operator in exactly the same manner regardless of whether an encrypting device is connected to the facsimile apparatus, and regardless of whether the encrypting device includes an NCU. When the operator picks up a handset, HOOK 16 and HOOK-A 25 both rise from logical "0" to logical "1". The operator confirms an outgoing call or a signal from another party's facsimile apparatus and presses a start button. Since HOOK-A 25 is at logical "1", the flow controller 11 causes CML 23 to rise from logical "0" to logical "1", thereby starting the transmitting/receiving operation. When the operator hangs up the handset, HOOK 16 and HOOK-A 25 revert to logical "0". When the transmitting/receiving operation subsequently ends, CML 23 reverts from logical "1" to logical "0". Even if DSR 22 at logical "1" is output by an encrypting device 200 connected to the apparatus, it does not affect the state of HOOK-A 25, which is the output of an OR gate 21, the reason being that the Q output 24 of flip-flop 20 is set by CML 23 and CML 23 is at the "1" level, therefore, the Q output 24 of flip-flop 20 is logical "0".
摘要翻译：公开了一种传真装置，其中操作者以完全相同的方式执行发送/接收操作以及复制操作，而不管加密设备是否连接到传真设备，并且不管加密设备包括一个NCU。当操作员拿起手机时，HOOK 16和HOOK-A 25都从逻辑“0”升高到逻辑“1”。操作员确认来电或来自另一方的传真设备的信号，并按下开始按钮。由于HOOK-A 25处于逻辑“1”，流控制器11使CML 23从逻辑“0”升高到逻辑“1”，从而开始发送/接收操作。当操作员挂断手机时，HOOK 16和HOOK-A 25恢复为逻辑“0”。当发送/接收操作随后结束时，CML23从逻辑“1”恢复到逻辑“0”。即使逻辑“1”的DSR 22由与设备连接的加密设备200输出，也不影响作为或门21的输出的HOOK-A 25的状态，其原因在于Q输出触发器20的24由CML23设置，CML23处于“1”电平，因此触发器20的Q输出24是逻辑“0”。
