摘要： A magnetic tape recorder for recording as well as for playback of sound, having a noise suppression device, and sensor member with an abutment surface for engaging against an unopened break through tab of a tape cassette for causing a locking mode for the recording device to be inoperative. The sensor member has an additional abutment surface arranged such that the latter abutment surface senses the wall of the cassette outside of the broken-through penetration opening of the cassette and the insert movement of the sensor member is limited in the opened penetration opening. The sensor member is connected with the locking device; such that in the absence of the limitation due to the absence of a cassette, the locking device, is also inoperative.

摘要： A cassette tape recorder for use with a cassette which has at least one opening on its wide side, through which opening, upon the insertion of the cassette into the device, there can be inserted at least one winding mandrel for engagement in the core of the tape spool, the cassette having at least one opening in one of its narrow sides, in which last mentioned opening, after the setting of the cassette on the winding mandrel by means of a feed device (which feed device can be transferred against the action of a spring into the operating position by means of a first control element and which feed device is again releasable out of this operating position by means of a second control element), the magnetic head is insertable in a direction perpendicular to the axis of the winding mandrel for the purpose of recording or playback, and which contains means which prevent a mechanical stressing of the magnetic head if with an inserted magnetic head, attempt is made to take the cassette from the device. The control element for release of the feed device for the magnetic head is moveable in the direction of the grabbing movement of the hand for the inserted cassette and is arranged bordering directly contiguous to the cassette in a manner such that the cassette can only be grabbed after the control element has been moved.

摘要： A switching device for a cassette tape recorder with which the magnetic head, by means of a feed device which is actuatable by a solenoid, is introducable into an opening of the cassette and is again removeable by means of a spring, whereby in the circuit of the solenoid there are disposed in series a first and a second electronic switch and a mechanically controlled first contact pair, and the first electronic switch is controlled by the service control elements for the tape transport (recording/playback or stop), the second electronic switch being controlled by a photoelectric device which is disposed in the region of grabbing of the fingers upon insertion or removal of the cassette and interrupts the circuit of the solenoid as long as the light beam is interrupted by the fingers and the first contact pair is controlled by a sensing pin which projects into the reception area of the cassette and interrupts the circuit of the solenoid as long as no cassette is located in the device, so that the magnetic head automatically is brought into its position of being pulled back from the cassette when the grabbing by the hand takes place and the magnetic head remains in this position when no cassette is located in the operative position, so that the magnetic head never can come into contact with the cassette housing.
摘要翻译：一种用于盒式磁带录音机的开关装置，通过该磁头可以通过由螺线管致动的馈送装置将磁头引入到盒的开口中，并且可以通过弹簧再次移除，由此在螺线管串联设置第一和第二电子开关和机械控制的第一触点对，并且第一电子开关由用于磁带传送（记录/重放或停止）的服务控制元件控制，第二电子开关由光电装置控制，该光电装置设置在插入或取出盒式磁带时抓住手指的区域，并且只要光束被手指中断，并且第一触点对由只要没有盒式磁带位于设备中，感测针就会突出到磁带盒的接收区域并中断电磁线圈的电路，所以使磁头自动进入其被抓住时从卡带被拉回的位置，并且当磁带没有位于操作位置时磁头保持在该位置，使得磁头不能与盒式外壳接触。
