    摘要: A contact lens for intraocular observation capable of optically recognizing an inner portion of an eyeball by contacting the contact lens on a surface of a cornea of an eye to be inspected through a light ray transmitted through an inner portion of the contact lens comprising: an optical path dividing member provided on an optical path for leading a light ray incident on the inner portion of the contact lens to the eye to be inspected for dividing a portion of the light ray on said optical path; and an index provided at a position approximately optically conjugate with a portion to be observed of the eye to be inspected on a divided optical path divided by the optical path dividing member. The portion to be observed and said index can optically be recognized by at least partially superposing a first image of the index on a second image of the portion to be observed.

    摘要: Arrangement toy, including a plurality of elements to be arranged on arrangement areas, comprising a device which judges and indicates whether or not arrangement of the elements are arranged in the arrangement areas in a pre-determined order when a switch is depressed after arrangement of the elements is completed. Each of the elements is provided with a magnet or magnetic substance at a pre-designated position therein.A plurality of corresponding operative substances are fixed at such positions where the magnets or magnetic substances of the arranging elements are opposed thereto, respectively, when each arranging element is placed in its pre-determined position. The operative substances are provided independent of each other and cooperate with magnets or magnetic substances only when the arranging elements are arranged in the pre-determined order. Such cooperation is communicated to signalling means through withholding means. When the withholding means is released, the signalling means indicates that one or more of the arranging elements are positioned in the pre-determined order.
