Abstract
Abstract A pinball game contains a plurality of drop target members each mounted for vertical movement between a raised position, above the playfield of the pinball game, and a lowered position below the playfield. Each target member is maintained in its raised position by a latch, and the target member may be knocked off its latch by impact from a pinball, causing the target member to drop to its lowered position. A latch may be withdrawn from a supportive position for its target member, causing the target member to drop without having undergone impact by a pinball. Structure is provided to elevate the target members to their raised positions, and there is a controller programmed to withdraw selected latches following the elevation of the target members.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
247 words
A drop target assembly for a pinball game wherein pinballs are put in play on a playfield, said drop target assembly comprising: a plurality of target members; means mounting each of said target members for movement, independent of the other target members, between a raised position in which the target member extends above said playfield and a lowered position in which the target member is located below the playfield; means actuable to elevate each target member to its raised position; a plurality of latch means, one for each target member; means mounting each latch means for movement, independent of the other latch means, between operative and inoperative positions; means normally urging each latch means toward its operative position; each of said latch means and its correponding target member comprising means cooperating to hold the target member in its raised position, when the latch means is in an operative position, and for permitting the target member to drop to its lowered position in response to impact, from a predetermined direction, by a pinball in play on the playfield; means, for each latch means, actuable to move said latch means from its operative to its inoperative position, thereby permitting the corresponding target member to drop to its lowered position; means operable to actuate individual latch-moving means in accordance with a predetermined program; and means for operating said actuating means in response to the movement of a predetermined number of said target members from their raised to their lowered positions.
Claim 2
Dependent Claim
