摘要： A plurality of parallel push rods is vertically movably supported between an inactive position to which each push rod is normally biased and an active position in which it engages a drive mechanism of the tape recorder. Each of the rods is provided with a notched portion. A latch bar having a plurality of projections arranged along one edge thereof is pivotally supported at one end and has its opposite end biased toward the push rods to permit its projections to engage each of the notched portions of the rods. The notched portion of the rods has a first notch with which the associated projection of the latch bar normally engages when the push rods are in the inactive position and a second notch with which that projection engages to lock the push rod in the active position. At least one of the push rods is provided with a protrusion in the direction toward the latch bar to cause it to rotate about its pivot to unlock another push rod from the active position.
摘要翻译：多个平行推杆可垂直地可移动地支撑在每个推杆通常被偏置的非活动位置和与磁带记录器的驱动机构接合的有效位置之间。每个杆设置有切口部分。具有沿着其一个边缘布置的多个突起的闩锁杆在一端枢转地支撑，并且其相对端朝向推杆偏置，以允许其突起接合杆的每个切口部分。棒的切口部分具有第一切口，当推杆处于非活动位置时，闩锁杆的相关联的突出部通过该第一切口与第二切口啮合，并且第二凹口与该突起接合以将推杆锁定在主动位置。至少一个推杆在朝向闩锁杆的方向上设置有突起，以使其围绕其枢轴旋转，以从主动位置解锁另一推杆。
