Title: Opening device for cartridge shutter
Inventor: ISHIDA MASAHIRO
IPC: G11B17/043
Filed: 1989-06-16
Abstract: PURPOSE:To miniaturize a drive device by setting the rotary center of an opening means at the deeper back of the cartridge storage position of a drive device and constituting the opening means by means of a main lever and an auxiliary lever. CONSTITUTION:The rotary center of the opening means which mechanically opens a shutter by using a cartridge 21 is set at the deeper back than the cartridge storage position in the drive device and the means consists of the main lever 24a and the auxiliary lever 24b, both of which can rotate. Since the opening means of the shutter consists of two levers 24a and 24b, the shutter 22 can smoothly be opened without resistance with respect to the cartridge 21 with a large opening width even if the rotary center of the lever 24a is positioned at the deeper back of the drive device.

Title: Line printer
Inventor: MOCHIDA SADAYOSHI
IPC: B41J29/54
Filed: 1995-06-22
Abstract: PURPOSE: To prevent the movement of a printing unit into a housing at the time of opening a cover by providing a stopper plate so provided as to stop to guide the unit into the housing at the time of energizing the one end of a rocking unit downward in a line printer having the unit drawably provided from the housing. CONSTITUTION: When a rolled sheet is set to a sheet container 4, first housing unit 2 is drawn from a housing 1, and the engaged state of the protrusion 8a of a hook 9 is released by a lever 9a. Then, since a cover 8 is opened and the upper end of a stopper rod 22 becomes free, the rocking stopper 23c of an rocking unit 23 is energized at its one end by an energizing spring, and the rod 22 is raised. At this time, when the unit 2 is, for example, intended to be inserted into the housing 1 without closing cover 8, one end of the stopper 23c is stopped by a stopper plate 31. Thus, before the cover 8 is collided with the housing 1, the insertion of the unit 2 is prevented by the stopper 23c and the plate 31.

Title: Image forming device
Inventor: IMANISHI MASAHIRO
IPC: B65H33/08
Filed: 1994-07-07
Abstract: PURPOSE:To obtain an image forming device with a composite function in which output paper sheets are easily sorted. CONSTITUTION:The image forming device with a facsimile communication function, a copy function and a printer function is provided with a multi-stage paper feed device. The 1st stage of the paper feed device adopts a cassette 1 for A4 size and the 2nd stage uses a cassette 2 for A4R size.

Title: Differential pressure measuring apparatus
Inventor: NISHIHARA TADASHI
IPC: G01L9/12
Filed: 1981-09-30
Abstract: PURPOSE:To lessen static pressure span errors, temperature span errors, and fastening span errors, by a method wherein bellows are utilized as pressure receiving elements and the radial strain of a housing is absorbed by a cylinder  part provided at the end of the bellows. CONSTITUTION:High measuring pressure is introduced into a measuring room 61 through an inlet port 611, and low measuring pressure is introduced into a measuring room 71 through an inlet port 711. The pressure introduced is transmitted to sealed liqid 4 and 5 through seal diaphragms 23 and 24. The pressure is then converted into the force at both inside and outside of a bellows 11. The displacement taken place at the top of the bellows 11 causes a movable electrode 12 to migrate, resulting in the change of inter-electrode capacitance between electrodes 12 and 16, and between electrodes 12 and 17.
