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.
In a tape player including a frame; the improvement in lockable mechanisms responsive to the insertion of a tape cassette into the player, said mechanisms comprising a slide member provided so as to slide relative to said frame; an actuating member rotatably fitted to said slide member; a lock-operating member mounted for movement relative to said actuating member in response to the insertion of a cassette into the tape player; an engaging member provided on said actuating member so as to engage with and disengage from said slide member; a projection formed on said lock-operating member for operating said engaging member, said projection being adapted to engage with and move said engaging member when said engaging member is operated in one direction; first guide means for guiding said engaging member into a locking position; means for resetting said lock-operating member; and a second guide means for guiding said engaging member and letting said projection pass over said engaging member when said lock-operating member is reset, said projection having on one side face thereof tow edges for changing over a guiding direction for the engaging member and, on another side face thereof, an inclined edge for pushing said engaging member into said second guide means to reset said projection.
