Title: Binoculars
Inventor: AKAGI KATSUTO
IPC: G02B7/28
Filed: 1991-05-17
Abstract: PURPOSE:To prevent the base line length of a range finding light from being affected by eye width adjustment, and to improve the accuracy of the range finding by constituting a binoculars so that a distance between objective lenses is not varied, although a distance between a pair of eyepieces is varied at the time of adjusting the eye width. CONSTITUTION:When eye width is adjusted by using a lens driving amount calculating means and a lens driving means, a distance between a pair of eyepieces is varied, but a distance between objective lenses 2, 3 is not varied. Therefore, the position of light receiving windows 8, 9 the range finding provided between a pair of objective lenses 2, 3 is not varied, as well. Accordingly, since base line length of a range finding light is not affected by eye width adjustment, the accuracy of the range finding is improved. Also, as for the objective lenses 2, 3, they become compact since its interval can be narrowed to eye width or below, and even if a pair of light receiving windows 8, 9 for the range finding are provided on the upper and the lower parts between its objective lenses 2, 3, the dimension in the transverse direction in the front part of the binoculars can be reduced, and its compact property is hardly spoiled.

Filed: 1983-08-04
Abstract: PURPOSE:To enable simple egg checking by inserting a tray set with eggs to an egg checking part by checking the eggs in said part when said tray is inserted therein and announcing the result thereof by lighting lamps. CONSTITUTION:A tray 2 set with eggs E in an egg housing part H is inserted into a body 1 from an inlet side 5 thereof. The normally opening contacts of a relay are closed by the tray 2.

Title: Image reader
Inventor: KOJIMA AKIO
IPC: H04N1/04
Filed: 1999-05-24
Abstract: PROBLEM TO BE SOLVED: To provide an image reader which reads an image with fixed resolution, even if the speed is not constant. SOLUTION: A sampling circuit 19 detects the output of a speed detection circuit 18 and a sensor drive circuit 5 calculates the cycle ti of a transfer pulse SH, based on the formula ti=1÷(Y×Vx), in accordance with a vertical scanning speed Vx of a detected line sensor 1. Here, Y is the resolution in the vertical sub-scanning direction. The circuit 5 produces a pixel clock and an image valid signal, which are synchronized with the pulse SH in addition to the pulse SH and outputs them to the sensor 1. Because the sensor 1 transfers electric charges of a photosensitive part to a shift register for output with an input of the pulse SH as a turning point, the period of the pulse SH becomes the storage time for an optical signal of the sensor 1.

Title: Sheet cutting device
Inventor: KOJIMA TAKASHI
IPC: B26D1/20
Filed: 1989-06-06
Abstract: PURPOSE:To prevent production of a gap between moving and stationary blades at an anticipatory intersection point even when the manufacture error of the moving blade is increased and to improve a cutting quality by a method wherein the moving blade is positively inclined based on the stationary blade so as to make concentrated contact with each other at the anticipatory intersection. CONSTITUTION:A sheet S is cut at an intersection A, anticipatory during movement of a circular blade 10, of two intersections A and B between a circular cutting edge 12 and a linear cutting edge 47. Since the circular blade 10 and a leaf spring 42b are brought into concentrated contact with each other at a straight line for interconnecting the two intersections A and B, a gap at the intersection A between the circular cutting edge 12 and the linear cutting edge 47 is kept at a proper value, and a cutting quality is improved. Since a sheet surface 46b on the leaf spring 42b side is separated away from a sheet support surface 46a on the leaf spring 42a side in the direction of the rotary central line of the circular blade 10, the cut edge of the sheet S is sufficiently separated away from a taper surface 80 in the direction of the rotation central line of the circular blade 10 until the cutting edge is brought into contact with the taper surface 80 of the circular blade 10. This constitution prevents bending of the sheet a during cutting.
