    • In a tape cassette recording and/or reproducing apparatus capable of selective operation with a relatively large or small-sized cassette containing a respective pair of rotatable reels having a relatively large or small center-to-center distance, respectively; a cassette holder is movable between a cassette receiving and discharging position and a loading position and can receive a selected one of the large and small-sized cassettes when in the receiving and discharging position and can convey the selected cassette to the loading position; a pair of reel bases are movable relative to each other for varying the center-to-center distance therebetween; a reel base adjusting device is selectively driven in first or second modes for respectively moving the reel bases to first or second positions wherein the center-to-center distance therebetween is suitable for engagement with the reels of a large or small-sized cassette; a detector detects the size of a cassette received in the holder and assumes different conditions when detecting the large and small-sized cassettes, respectively; and a drive member is movable with the holder at least part of the way from the receiving and discharging position toward the loading position and is responsive to the condition of the detector for selectively driving the reel base adjusting device in the first and second modes, respectively, so as to dispose the reel bases in positions suitable for the size cassette being conveyed by the holder to the loading position.
    • 在能够分别具有相对较大或小尺寸的盒的选择性操作的带盒记录和/或再现装置中,该盒子分别具有相对较大或小的中心到中心距离的相应的一对可旋转卷轴; 磁带盒保持器可在盒接收和放电位置与装载位置之间移动,并且当处于接收和放电位置时可以接收大小盒中的所选择的一个,并且可以将所选择的盒传送到装载位置; 一对卷轴基座相对于彼此可移动以改变它们之间的中心到中心距离; 在第一或第二模式中选择性地驱动卷轴底座调节装置,以分别将卷轴基座移动到第一或第二位置,其中,它们之间的中心到中心的距离适合于与大型或小型磁带盒的卷轴接合; 检测器检测到在保持器中接收到的盒的尺寸,并分别检测大小盒时呈现不同的条件; 并且驱动构件能够与保持器一起从接收和排出位置朝着装载位置的至少一部分移动,并且响应于检测器的状态分别以第一和第二模式选择性地驱动卷轴基座调节装置 以便将卷轴基座布置在适合于由保持器传送到装载位置的尺寸盒的位置。
