IPC: G02B13/22
Filed: 1994-03-23
Abstract: PURPOSE:To easily set a desired image formation magnification, and to hold an inter-object distance so as to be constant by changing the image formation magnification while holding such a state that a main light beam is made incident and emitted in parallel to an optical axis. CONSTITUTION:This system consists of three groups of lenses respectively having a positive focal distance, and focal distance f1 to f3 the first, second, and third group lenses fulfill the relation of expressions I and II. Then, the first, second, and third group lenses are arranged so as to be successively movable in the optical axial direction, and the focal distance of an entire optical system can be substantially infinite by making the synthesized focusing of the first group lens and the second group lens coincide with the front side focal point of the third group lens. Moreover, the entire optical system is arranged so as to be successively movable in the optical axial direction, and the object distance can be properly selected. Even when the object distance is changed, the formation magnification is not changed, and the variable magnification can be attained while holding the inter-object distance so as to be constant by moving the entire optical system and adjusting the object distance.

Filed: 1989-03-03
Abstract: PURPOSE:To attain the use of a mouse in a small space and to improve the operability of the mouse by continuing the movement of a cursor on a CRT even after the mouse stops its movement. CONSTITUTION:A mouse is provided with a continuous movement signal generating switch 1 together with a moving direction detecting part 2, a cursor movement signal generating part 3, a transmission data production part 4, and a mouse main body 5. When the switch 1 is depressed, a continuous movement signal 101 is validated and then invalidated in the case of releasing the switch 1. The part 3 receives the direction data 102 from the part 2 and stores the direction in an instant when the signal 101 is validated. Thus the information is continuously sent to the part 4 even after the mouse stops its movement as if the mouse were moving in the direction. The mouse stops when the signal 101 is invalidated. Consequently, the operability of the mouse is improved in a small space.
