摘要： A checker-arm chain lubricating apparatus is provided that efficiently and surely performs lubrication on a small-size chain and a chain traveling at high speeds. When a checker arm, oscillated by a chain, is returned by the force of a return spring, a cam face of a plunger activating cam fixed to a cam shaft together with the checker-arm operates a plunger of a pump unit via a cam follower to jet lubricant from a lubricating nozzle to the chain. The above-mentioned cam face is formed at a position radially deviated from the center of the cam shaft and the normal direction of the cam face is at generally right angles to the axis of the cam shaft. Consequently, the plunger can be rapidly operated by a small oscillation angle of the checker arm and efficient lubrication in synchronization with chain travel can be performed by a small amount of lubricant jetted from the lubricating nozzle at high speeds.
摘要翻译：提供了一种检查臂链条润滑装置，其在小型链条和高速行驶的链条上有效且可靠地执行润滑。当由链条振荡的检查器臂由复位弹簧的力返回时，与校验臂一起固定到凸轮轴的柱塞启动凸轮的凸轮面经由凸轮从动件操作泵单元的柱塞将润滑剂从润滑喷嘴喷射到链条上。上述凸轮面形成在从凸轮轴的中心径向偏离的位置处，并且凸轮面的法线方向大致与凸轮轴的轴线成直角。因此，柱塞可以通过检查臂的小的振荡角快速操作，并且可以通过少量从润滑喷嘴高速喷射的润滑剂来执行与链条行进同步的有效润滑。

摘要： In a cassette for use in a magnetic recording and/or reproducing apparatus and which is of the type having a housing containing freely rotatable reels having magnetic tape wound thereon with the tape extending between said reels being guided to direct a run thereof across an access opening in said housing, an improved brake assembly is provided for automatically preventing excess slackness in the run of tape when the cassette is disengaged from the magnetic recording and/or reproducing apparatus and for automatically releasing the tape run when the cassette is so engaged. A holder having a resiliently flexible element slidably disposed in a gap provided therein is arranged with respect to a support element such that the free end portion of the element preferably having a low coefficient of friction normally urges a tape portion into pressing contact with the support element so as to provide the braking action. When the tape run is drawn out of the access opening or otherwise tensioned, however, the element is flexed thereby such that only the free end portion having the low coefficient of friction is in sliding contact with the tape, whereby the automatic release action is provided.

摘要： A tape cassette includes a housing; a supply reel rotatably mounted in the housing for supplying tape and having a lower flange section with teeth around the periphery thereof; a take-up reel rotatably mounted in the housing for taking up the tape; a pivot pin mounted in the housing between the supply and take-up reels; and a control member including a ring portion pivotally mounted on the pivot pin, a receiving plate secured to the ring portion and having a frictional contact surface in elastically forced contact with the underside of the lower flange section of the supply reel, and a lock member secured to the receiving plate, such that rotation of the supply reel in the rewind direction frictionally rotates the receiving plate about the pivot pin to pivot the lock member into engagement with the teeth to prevent rotation of the supply reel in the rewind direction and rotation of the supply reel in the forward playback direction frictionally rotates the receiving plate about the pivot pin to pivot the lock member out of engagement with the teeth to permit rotation of the supply reel in the forward playback direction.

摘要： A tape cassette is so arranged that an endless tape, stored in a tape accumulating portion in a cassette body, to which a front lid is pivotally movably secured, to thereby assume an open position and a closed position with respect to a front opening in the cassette, and pulled out of the cassette body, is again drawn into the cassette body, by means of a tape drawing reel mounted in a position displaced to one side from the center of the cassette body. A pair of elastic members are disposed in an elastically contracting relation to each other, with the free ends thereof facing a tape discharge gate within the cassette body, so that the endless tape can pass through the pair of elastic members. The tape cassette further includes a rotatably mounted, reverse rotation check member; and a flexible member attached at one end or in the intermediate portion thereof to the cassette body, with the other end maintained in pressure-contact with an elastic member surrounding the flank portion of the tape drawing reel. The flexible member is slidably connected in a portion between the fixed portion and the aforesaid other end to the reverse rotation check member. When the tape drawing reel is rotated in a reverse direction, the aforesaid other end portion of the flexible member is strongly pressed against the elastic member while being deformed, thereby pressing the reverse rotation check member against the tape drawing reel thereby impeding reverse rotation thereof.
摘要翻译：盒式磁带被布置为使得存储在盒体中的带存储部分中的环形带被可枢转地移动地固定到其上，从而相对于前盖中的前开口呈现打开位置和闭合位置磁带盒，并从磁带盒体拉出，再次通过安装在从盒体中心向一侧偏移的位置上的磁带引导盘进入磁带盒体。一对弹性构件彼此弹性收缩地设置，其自由端面向盒体内的带排出门，使得环形带可以穿过该对弹性构件。带盒还包括可旋转地安装的反向旋转检查构件; 以及在其一端或其中间部分附接到盒体的柔性构件，另一端与围绕带状牵引盘的侧面部分的弹性构件保持压力接触。柔性构件在固定部分和上述另一端之间的部分中可滑动地连接到反转止动构件。当带状卷取卷轴沿相反方向旋转时，柔性部件的上述另一端部在变形的同时被强力地压靠在弹性部件上，从而将反转止动部件压靠在带状卷取卷轴上从而阻止其反转。
