摘要： PROBLEM TO BE SOLVED: To reduce a load at the time of operating a selecting means. SOLUTION: As the time of detecting a misrecording preventing state of a cassette tape 20 is this misrecording preventing device 30, a pawl detecting lever 31 (reverse direction detecting means) is arranged in a prescribed position in accordance with movement of the pawl detecting laver 31 or the pawl detecting laver 32, and also the selecting means 40 composed of a direction laver 34, a recording laver 35 and a guard lever 36 is operated in accordance with the traveling direction of a tape. When a recording operation of the selecting means 40 is regulated, misrecording is prevented, and when this is not regulated, the recordable state is effected. Since the selecting means 40 is independently operated at the time of detecting the misrecording preventing state, energizing force of a return spring 31f or a return spring 33d as energizing means does not work on the selecting means 40, and hence power consumption at the time of operating selecting means 40 is reduced.

摘要： PURPOSE: To detect an end part of a magnetic tape in a simple method by specifying a remaining time of the magnetic tape from revolution numbers of a feed reel and a wind reel and a run time of the tape. CONSTITUTION: Reel pulse signals indicating rotation cycles of a feed reel 12 and a wind reel 14 are generated from relay rotation detectors 22 and 24 set below the reels 12 and 14, respectively. The reel pulse signals are sent to a remaining time detector 30. An FG pulse signal corresponding to a rotation speed of a motor of a capstan unit 20 is generated at a frequency generator 18 and fed to the remaining time detector 30. The detector 30 operates and specifies a remaining time of a magnetic tape 10 from the rotation cycles of the reels 12, 14, a run time of the magnetic tape selected by a memory unit 26 and a count of FG pulses. Then, a tape end position detector 50 compares the detected remaining time with a preliminarily set threshold value of an end part, thereby detecting the end part of the tape.

摘要： PURPOSE:To prevent the damage and the failure of a detection lever and a detection switch by making an one end side arm part a different member from the other end side arm part and attaining to bend it. CONSTITUTION:When no erroneous erasure preventing lug 5A exists on a loaded cassette 5, a first lever and a second lever are drawn by a spring 10 and rotated clockwise around a pivot. The tip of the bended handle part 2c of the lever 2 enters a recessed part 5a where the lug is eliminated, and the operating part 7c of the lever 7 is separated from a detection switch 6 to OFF operate the switch. When the lug 5A exists on the cassette 5, the tip of the bended handle part 2c is impossible entering the recessed part 5a, and the operating part 7c is pressed to the switch 6. At this time, since the spring 10 is lengthened further and rotated clockwise around the pin 8 of one end side arm part 7a of the lever 7, the excess press for the switch 6 is evaded, and the failure of the switch 6 is prevented.
