    • A camera includes a taking lens system changeable in focal length between at least a short focal length suitable for wide-angle photography and a long focal length suitable for telephotography. The lens system is held in a lens barrel which is axially displaced by means of a motor to change the lens system between at least the two different focal lengths. The camera is provided with a controller for sequentially controlling the motor to move the lens barrel in one axial direction so as to change the lens system to have one of the different focal lengths selected by a focal length selecting switch, to move the lens barrel in the opposite axial direction when the lens barrel does not reach a position wherein the taking lens system has the selected focal length in a predetermined time period, and to stop when the lens barrel reaches the position wherein the taking lens system has another one of the different focal lengths. For detecting the lens barrel at the axial position where the taking lens system has the different focal lengths, the camera is provided with a detector for detecting an unusual motion of the lens barrel in cooperation with the controller.
    • 相机包括可在适合于广角摄影的至少短焦距和适合于长焦摄影的长焦距之间的焦距可变的拍摄镜头系统。 透镜系统保持在透镜筒中,透镜筒通过电机轴向移位,以在至少两个不同焦距之间改变透镜系统。 相机设置有控制器,用于顺序地控制电动机沿一个轴向移动透镜镜筒,以便将透镜系统改变为具有由焦距选择开关选择的不同焦距之一,以将透镜镜筒移动到 当镜筒没有到达其中拍摄镜头系统在预定时间段内具有选定焦距的位置时相反的轴向方向,并且当镜筒到达其中拍摄镜头系统具有另一个不同的位置时 焦距 为了在拍摄镜头系统具有不同焦距的轴向位置处检测镜筒,相机配备有用于与控制器协作检测镜筒的异常运动的检测器。

    • A method for matching and splicing webs that splices, by use of splicing tape, a rear end of a strip-shaped flexible backing that is drawn and conveyed from an old roll and a front end of a strip-shaped flexible backing that is drawn and conveyed from a new roll, in a state in which the front end and the rear end are matched, wherein the method performs matching and splicing by executing: a preparation step of performing matching and splicing preparations by retaining a front end of a strip-shaped flexible backing of the new roll with one of a pair of cutting drums, and supplying splicing tape to a pair of splicing drums, respectively; a cutting step of cutting with the pair of cutting drums a strip-shaped flexible backing of the old roll and a strip-shaped flexible backing of the new roll in an overlapping state after the preparation step; a feeding step of feeding to a splicing position a rear end of the strip-shaped flexible backing of the old roll and a front end of the strip-shaped flexible backing of the new roll that are cut in the cutting step, as they are in a matched state; and a splicing step of using the pair of splicing drums to adhere and attach splicing tape to each of a front surface side and a rear surface side of a matching portion that is fed to a splicing position in the feeding step; wherein, in the preparation step, at least one of the pair of splicing drums is driven independently, and in the cutting step, the feeding step and the splicing step, the one of the pair of splicing drums is driven in synchrony with other drums.
    • 一种用于匹配和拼接网的方法,其通过使用拼接胶带将从拉伸的带状柔性背衬的拉伸和输送的带状柔性背衬的后端接合, 在前端和后端匹配的状态下,从新的卷筒输送,其中,所述方法通过执行以下步骤执行匹配和拼接:准备步骤,通过保持带状的前端 使用一对切割滚筒中的一个的新卷筒的柔性背衬,并将拼接胶带分别提供给一对拼接滚筒; 在所述制备步骤之后,以所述一对切割滚筒切割所述旧卷的带状柔性背衬和所述新卷的条形柔性背衬,处于重叠状态; 馈送步骤,将旧卷的带状柔性背衬的后端和新卷的带状柔性背衬的前端进给到拼接位置,该切割步骤在切割步骤中被切割 匹配状态 以及接合步骤,使用所述一对拼接鼓将拼接带粘合并将拼接带附接到在所述馈送步骤中被馈送到拼接位置的匹配部分的前表面侧和后表面侧中的每一个; 其特征在于,在上述制造工序中,独立地驱动上述一对拼接滚筒中的至少一个,并且在切断工序中,进给步骤和拼接工序中,一对拼接滚筒与其它滚筒同步地驱动。
