  • Patent number: 4344097
    Abstract: A lock mechanism for use in a tape player for locking a slide member provided slidably on a tape player frame. The slide member is attached by a pivotally movable actuating member. The actuation member is provided with a pin adapted to engage with and disengage from a locking hook portion formed on the slide member and provided in association with an operating member for carrying out a locking operation. The operating member has an engaging projection engageable with said pin to actuate the same. The frame has a first guide portion for engaging with the pin and guiding the same into a locking position and a second guide portion for letting the engaging projection pass during the resetting of the operating member. The engaging projection has, on one face, two side edges for changing over operational directions for the pin and, on another face, a diagonal edge for forcing the pin into the second guide portion to let the projection pass thereover.
