Claims

[Scope of utility model registration request]

The erroneous erasure prevention nail detecting member includes first and second pressed portions formed on the eject operating member, and a pressing member having elasticity and arranged to be interlocked with the eject operating member. When not in operation, the first pressed part is pressed by the elastic force of the pressing member, and this pressing urges the detection member in a direction to move to the detection position, and when the eject operation member is operated, it is linked to this operation. The pressing member is moved, and this movement releases the pressing force on the first pressed part and presses the second pressed part, and this pressing moves the detection member to a non-detecting position. A cassette tape recorder configured to prevent accidental erasure.
