摘要： PURPOSE:To facilitate the replacement of cleaners and also to realize a disk cleaning job even at the time of reproduction by securing such a constitution where a cleaning member can be taken out of a front operating part and the cleaning job is carried out independently of the shift of a reproduction stylus. CONSTITUTION:A rotary arm 50 can move reciprocatively between the outermost circumference and the innermost circumference of a disk 24 and also turn from the innermost circumference up to the waiting position of a cleaning means while holding this cleaning means. A cleaner revolving means includes a cartridge holder 51, a cam gear 55, a base 57, a pinion gear 59, etc. A drive rack 27 shifts linearly the cleaning means up to the outside of this cleaning device. A cleaner shift means includes a rail 28, a drive gear 29, a worm 32, a cartridge guide, etc., in addition to the rack 27. A drive means contains a motor 31 which drives a cleaner revolving means and shifts the cleaner shift means. In such a constitution, the cleaner can be easily replaced at a front operating part and also a cleaning job is carried out even at the time of reproduction.

摘要： PURPOSE:To make it hard to develop internal stress and especially make it possible to shrink just after the outsert molding of a long rack gear or the like by a method wherein the rack gear to transform a rotary motion into a linear motion is molded integrally with a thin metal sheet so as to be allowed to shrink in a longitudinal direction. CONSTITUTION:A thin metal sheet 10 has one positioning hole 11 and a plurality of elongated holes 12-19, one corner of each of which is square and the other corner is curved [a square cornered hole has a mark (a) at the end of the hole numeral and a curved cornered hole has a mark (b)]. As an outsert molded item, a rack gear 20 is constituted in such a manner that the elongated holes 12a-19a are not molded since the struts of a mold are formed in said holes. On the other hand, the elongated holes 12b-19b are molded so as to act as anti-rotation catches. Accordingly, the rack gear 20 constituted in a mold extends as far as to the end face 10a of the thin metal sheet, resulting in allowing to shrink to a gear form through the shrinkage after molding. In other words, the sizes of the struts of the mold are formed larger in the order of 19a>12a and, after the shrinkage, 12a-19a are left in the form of the holes, which have nearly the same size with one another. Consequently, internal stress is hard to be applied to the rack gear through shrinkage.

摘要： PURPOSE:To surely detect information of a cover in a disk player of automatic loading type, by providing a mediate member abutting with an uneven part that transmits recorded information of the disk in a holding mechanism and abutting the mediate member against a detection switch of the player. CONSTITUTION:Simultaneously with a disk holding mechanism 90 becomes 'cover disk holding state', an abutting pin 291 that became in contact with the convex part of a notched part for discriminating information provided on the cover 3 slides in the direction of rear face of the disk holding mechanism 90 and projects from a fixed wall by a fixed quantity. When 'cover holding state' is passed and the disk holding mechanism 90 is shifted in the direction X2, the projected abutting pin 291 comes into abutting against corresponding cover detection switch 295 and judges that it is the convex part. Thus, as the information detecting mechanism of the cover 3 is divided into a holding means and a detecting section, drawing of lead wires is eliminated, and the main body can be made thin as it is provided in the direction of shifting.

摘要： PURPOSE:To perform video recording regardless of the video recording is performed indoors or outdoors by incorporating a light source in a lens barrel and to supply a proper quantity of light to only a subject by employing a zooming mechanism. CONSTITUTION:Light from the light source 33 passes through the circumferential part 34b of a convergent lens 34 and is reflected only at the circumferential part 35b of a hollow mirror to emit the light to the outside through lens systems 28, 17, 13, 12, 11, 3, 2, and 1. At this time, the irradiation range of the light is determined by a focusing lens 1 and it coincides with the range of the photography of an object by a photographic lens system. When a lens holding member 14 is as shown by a dotted line, zooming operation is in a telephoto side. Incident light from the object froms an image on an image pickup surface 27 through the lens systems 1, 3, 11, 12, 13, 17, and 28, hollow part 35a of the hollow mirror, and lenses 29, 30, 31, and 32, but light from the light source 33 is reflected only at the circumferential part 35b of the hollow mirror 35, so no excessive light strikes the image pickup surface.
摘要翻译：目的：无论视频记录是在室内还是室外进行，都可以通过在镜筒内装入光源来进行视频录制，并通过使用变焦机制向适合对象提供适量的光。构成：来自光源33的光通过会聚透镜34的圆周部分34b，并且仅在中空反射镜的周向部分35b处反射，以通过透镜系统28,17,13,12向外部发射光，此时，光的照射范围由聚焦透镜1确定，并且与摄影透镜系统的物体的摄影范围一致。当透镜保持构件14如虚线所示时，变焦操作在远摄侧。来自物体的入射光通过透镜系统1,3,11,12,13,17和28，图像拾取表面27上的图像，中空反射镜的中空部分35a以及透镜29,30,31和 32，但是来自光源33的光仅在中空反射镜35的周向部分35b反射，因此没有过多的光照射到图像拾取表面。

摘要： PURPOSE:To enable focusing while performing zooming by providing an operating means for zoom operation to a focusing ring. CONSTITUTION:While an operating switch 3 is in a neutral position, the 1st contact piece 10 and the 2nd contact piece 11 do not contact with a contact point 18 and a contact point 19 which are formed of a conductive material and are provided at the front ends of a switch 5 on a wide side and a switch 6 on a telephoto side and therefore a DC motor 14 does not operate. If the wide operating surface 3a of the switch 3 is pushed, the contact point 18 of the switch 5 conducts with the piece 1 and a zooming operation can be made even if the ring 4 is turned in any way. The 1st DC motor switch 20 and the 2nd DC motor switch 21 are changed over to contact points C1 and C2 sides, thus changing over the rotating direction on the motor 14 side in this stage is completed. The switches are similarly changed over to the contact point d1, d2 sides in the telephoto operation as well and therefore the motor 14 is run forward and backward in accordance with the telephoto operation and wide operation.

摘要： PURPOSE:To prevent backlash in an optical axis direction by pressing an engaging member allowed to be engaged with the opposed inclined planes of a guide groove of which sectional shape rectangular to the longitudinal direction is like a trapezoid always to the guide groove by an exciting means and by engaging the engaging member to the guide groove at the opposed inclined planes. CONSTITUTION:A cam follower 19 set up so that the diameter (d) is smaller than the expanded width W of a cam groove 16 and larger than the narrow width W' is fitted loosely and slidably to an axis 18 and pressed from the lower part to the cam groove 16 by a plate spring 20 to be engaged with the opposed inclined planes. If a moving lens barrel 12 is turned against a fixed lens barrel 11 the cam groove 16 is moved against the cam follower 19 and the lens barrel 12 is moved in the optical axis X direction while being turned. Even if the accuracy of the groove widths W, W' is low, the lens barrel 12 is prevented from the generation of backlash in the optical axis X direction because the cam follower 19 is always pressed to the opposed inclined planes.

摘要： PURPOSE:To prevent backlash in an optical axis direction by pressing and engaging an engaging member having a trapezoidal sectional shape in the rectangular direction to the longitudinal direction of a guide groove and allowed to be engaged with the guide groove at its opposed inclined planes always to/ with the guide groove by an exciting means. CONSTITUTION:A circular truncated cone type cam follower 19 set up so that the diameter (ld) of its small diameter part is smaller than the groove width W of a cam groove 16 and the diameter D of a large diameter part is larger than the groove width W is fitted loosely and slidably to an axis 18 and pressed from the lower part to a cam groove 16 by a plate spring 20 so that the opposed inclined planes are engaged with the cam groove 16. If a moving lens barrel 12 is turned against a fixed lens barrel 11, the cam groove 16 is moved against the cam follower 19 and the lense barrel 12 is moved in the optical axis X direction while being turned. Even if the accuracy of the groove width W is low, the lens barrel 12 is prevented from the generation of backlash in the optical axis X direction because the cam follower 19 is always pressed to the cam groove 16 at the opposed inclined planes.
