Title: Wheel cassette mounting guide structure for printer
Inventor: NAGAYA SHUZO
IPC: B41J1/30
Filed: 1985-04-19
Abstract: PURPOSE:To guide a cassette and prevent a ribbon from being caught when a wheel cassette is mounted by forming a guiding surface of the wheel cassette through narrowing the tip width between the protrusions over which the ribbon of the ribbon cassette is stretched. CONSTITUTION:Between the two widths A and B, inclined guide surfaces 23 and 24 are formed to guide a wheel cassette 21 to a suitable place in the rear of a cutout concave 22 at the time of mounting of the cassette. The wheel cassette 21 stores a type wheel 25, and is guided by the guide surfaces 23 and 24, and through stretcher protrusions 18 and 19 for the ribbon 20 of the ribbon cassette 17 it is mounted on the carrier 14. Since the tip width between the stretcher protrusions for the ribbon of the ribbon cassette is narrowed to form the guiding surfaces of the wheel cassette, the ribbon cassette is guided by the guiding surfaces to a suitable position, resulting in the minimum occurrence of the ribbon being caught.

Abstract: PROBLEM TO BE SOLVED: To suppress deformation of a pressure plate part when a tap bolt is fastened tightly by forming a penetrating hole for penetrating a pair of outer side flat surfaces on a shaft, and forming a pair of holes formed on positions where a pair of pressure plate parts are conformed to each other, on a position conformed to the penetrating hole. SOLUTION: A penetrating hole 15 for penetrating a pair of outer side flat surfaces 12 which are formed in parallel with each other is formed on the top end part of a shaft 11. A pair of circular holes 16 are formed on positions which are conformed to each other at the width direction center part of a pair of pressure plate parts 7a', 7b' for composing a yoke 2a. In the case where the yoke 2a and the shaft 11a are connected and fixed to each other, the shaft 11a is inserted to the deep part of the base end part 6 of the yoke 2a, both circular hole 16 and the penetrating hole 15 are conformed to each other, a tap bolt 14a is inserted, a nut 18 is screwed and fastened tightly.  It is thus possible to prevent the inner side flat surfaces 8 of the pressure plate parts 7a', 7b' from being brought in tightly contact with the outer side flat surface 12, and also it is possible to prevent both pressure plate parts 7a', 7b' from forming in a non parallel with each other. It is possible to improve connecting strength of the shaft 11a and the yoke 2a.

Abstract: PURPOSE:To enable sufficiently-stable and highly-precise measurement of a current against vibration by disposing three non-polarization beam splitters in combination in a light emitting-sensing element and by unifying thereby forward and backward optical paths between the light emitting-sensing element and a Faraday effect material. CONSTITUTION:Lights emitted from three LEDs in an E/O converter 21 which is driven by a drive circuit 1 in an electronic circuit 15 proceed to a light emitting-sensing element 13 and they turn to be three linearly polarized waves through three polarizers 24a to 24c of which planes of polarization are shifted by 60 deg. from one another. Paths from a light emitting element to a light sensing element are unified by three non- polarization beam splitters 25 to 27. A unified polarized wave passes through a spatial optical path 28, reaches a turn-round integration type Faraday effect material 10 disposed so that a conductor 9 is inserted therein, turns round through the effect material 10 and is reflected by a mirror 17, and it goes back through the forward path and is emitted. Thereafter it passes through an analyzer 29 via the splitters 26 and 25 and is led to a photoelectric converter 32 and then a phase difference is detected by a phase detector 33. Thus, the light intensity ratio among the three lights does not change even when a part of the linearly polarized waves is absent.
