    • A tape cartridge capable of reliably identifying difference in type among tape cartridges without causing a tape drive side to have increased costs is provided. On the outer surface of a main case, an identification indicator is formed in a stripe shape having a grain printed portion and a mirror surface portion arranged alternately toward a loading direction of a magnetic tape cartridge onto a tape drive. An indicator format of the identification indicator on the magnetic tape cartridge, which is displaced and moved in the loading direction when loading operation of the magnetic tape cartridge onto the tape drive is conducted, is read by an optical reader mounted on the tape drive. This makes it possible to obtain type information on the magnetic tape cartridge on the tape drive side.
    • 提供了一种能够可靠地识别磁带盒之间的类型差异,而不会导致磁带驱动器侧增加成本的磁带盒。 在主壳体的外表面上,识别指示器形成为具有纹理印刷部分和镜面部分的条形形状,其朝着磁带盒的装载方向交替布置在带驱动器上。 通过安装在磁带驱动器上的光学阅读器读取磁带盒上的识别指示器的指示器格式,该磁带盒的识别指示器在将磁带盒装载到磁带驱动器上时被沿着装载方向移位和移动。 这使得可以获得磁带驱动器侧的磁带盒上的类型信息。

    • A film camera system, includes a housing with a front end carrying an objective, and a housing wall formed with an opening, a film magazine, and a single connecting member having at least one bore for allowing passage of a film from the film magazine into the housing via the housing opening and vice versa. The connecting member is secured to the film magazine and can be so attached to the housing that the film magazine is selectively positionable with respect to the housing in a first position essentially above the housing and in a second position essentially at the rear end of the housing, while providing a light-tight cover for the housing opening in the first and second positions of the film magazine.

    • There is disclosed a microfilm search device for detecting the presence of frames from a density change in the running direction of a microfilm, in which even if a frame contains therein a portion having substantially the same density as that of an interspace between frames, the portion is prevented from being incorrectly determined as between-frames, and frames are correctly detected to prevent a search error. The device is provided with an encoder for outputting a sampling signal for each predetermined feeding amount of the microfilm; plural density sensors for detecting a film density in different positions along a width direction within a frame travel width to output density signals; a binarizing section for binarizing the density signals into binarized signals having a logic ZERO or ONE in synchronization with the sampling signal; a determination section for detecting the presence of frames using a logical product or a logical sum of the plural binarized signals to output a determination signal; and a searching section for searching for a desired frame based on the determination signal.
    • 公开了一种微缩胶卷搜索装置,用于根据微缩胶片的行进方向上的浓度变化来检测帧的存在,即使帧中包含与帧之间的间隙基本相同的密度部分, 被阻止被错误地确定为帧之间,并且帧被正确检测以防止搜索错误。 该装置设置有编码器,用于输出针对微缩胶片的每个预定进给量的采样信号; 多个密度传感器,用于在帧行进宽度内沿宽度方向的不同位置检测膜密度,以输出密度信号; 用于将密度信号二值化为具有与采样信号同步的逻辑“零”或“1”的二值化信号的二值化部分; 确定部分,用于使用多个二进制化信号的逻辑积或逻辑和来检测帧的存在,以输出确定信号; 以及搜索部分,用于基于确定信号搜索期望的帧。
