    摘要: A device (1) for recording and playing back information signals has a connection apparatus (17) via which another such device (35) can be connected to the device (1) in order to carry out a copy operation. The other device (35) emits a control voltage U1 when a high level H with the "playback" mode of operation is switched on in the same. A copy instruction can be intentionally issued to the device (1) for example by actuating a key (46). The device (1) has a first detector (49) for detecting the control voltage U1 with a high level H emitted by the other device (35) and a second detector (50) for detecting an intentionally issued copy instruction. The "record" mode of operation is only switched on in the device (1) in order to carry out a copy operation in the event of both detectors (49, 50) being triggered simultaneously.
