Abstract

本发明的目的是尽可能迅速而方便地给操作者 提供与相应的实际磁带位置无关的有关磁带位置的 信息并能够迅速找到磁带的所需部分。
在插入盒式磁带(5)后自动地确定相应的实际磁 带位置,计数器(4)被设置为磁带位置的绝对值。
特别适用于VHS录像机。

Description

本发明基于一种记录装置。这种记录装置已公知于DE-OS3504311中。
这种类型的记录装置利用测试运转从卷盘的转速中就能够确定磁带相应的实际位置(一段时间)并且还能够确定与磁带相应的实际位置无关的磁带的剩余长度。在此,例如在按下按钮之后运行一个约2秒的短的测试运转,然后就以时和分显示剩余磁带长度。此外,在插入盒式磁带之后使计数器自动复“零”也是熟知的。
本发明的目的是对上述类型的记录装置进行改进以便能够给操作者迅速提供与磁带相应的实际位置无关的有关磁带位置的恰当而确定的信息,并且能够迅速而容易地找出磁带的所需部分。
上述任务已在由本发明中得到了解决。本发明进一步改进的优点在从属权利要求中给出。
因此,本发明能够在插入盒式磁带之后立即以数字的形式显示确定的磁带位置。上述确定的显示恰好等于磁带从头开始卷绕,计数器复“零”,磁带卷绕到上述磁带位置时所显示的磁带位置。在此,利用计数器就可重新计数,不需要把磁带倒带到起始端。插入盒式磁带之后显示的磁带位置被自动地作为磁带的起始端。其优点是以前所有的操作装置和其它操作特征无需更改就能使用。
本发明特别适用于录相机。但是,本发明也能用于如录音机的其它记录装置,例如DAT(数字录音磁带)录音机或模拟音频盒式录音机。
此外,计数器能够随时复“零”而不依赖于相应的实际磁带位置。如果需要的话,在显示时就能够以“零”显示相应的实际磁带位置。
在本发明的进一步改进中,手动输入(键盘输入)型盒式磁带的数据被用来确定磁带的位置。这对E195和E300型的盒式磁带特别有用,因为这些磁带还不能被这种装置自动清楚地识别。
以录相机为实例通过附图描述本发明。
图1表示将要插入盒式磁带的录相机。
图2表示已插入盒式磁带并且具有磁带位置绝对指示的录相机。
图1表示具有仍然空着的盒式磁带窗2、操作面板3、计数器4的显示、尚未插入的盒式磁带5和复“零”按钮6的录相机1。计数器4在位置“零”或在由先前磁带运转引起的任何其它位置上。
图2中盒式磁带5已被插入盒式磁带窗2。磁带插入后录相机1立即自动产生一个约2秒的短的测试运转。在上述测试运转期间,例如根据DE-OS3504311通过测量卷盘的转速就能确定实际的磁带位置。此后,已确定的该实际的磁带位置立即被计数器4以数字形式显示出来,其数字显示为“2640”。这也是开始计数时将计数器设置为“零”磁带以慢速或快进方式从头开始运转到如图2所假定的磁带位置时所显示的数目。在该测试运转中磁带加速运转一约5到10厘米的短距离。在测试运转结束确定了磁带位置之后将磁带倒带一段上述距离以便使其回到与测试运转无关的原来位置上。
利用按钮6计数器4能够被复位到“零”,不依赖于相应的实际磁带位置。由此,如果操作者需要的话,如图2所示的从磁带起始开始测量正确结果为2640的实际磁带位置被显示为0000。这样就删掉了实际的磁带位置2640。为了重新确定该实际磁带位置并且用计数器4把它显示出来,仅需把盒式磁带5从盒式磁带窗2中取出并重新插入。这样一来,用上述的方法就能自动地重新确定实际磁带位置2640并立即由计数器4显示。
