Title: Inkjet recording apparatus
Inventor: NAKAMURA HITOSHI
IPC: B41J19/18
Filed: 1993-04-02
Abstract: PURPOSE:To detect the remaining amount of ink by an inexpensive device with high accuracy by driving a head carrier loading an ink head and an ink tank with the use of a lead screw and providing a load detecting part at both ends of the lead screw. CONSTITUTION:When a recording data is transmitted to the recording apparatus and a motor shaft 1a of a head carrier driving motor 1 is rotated, a lead screw 4 is rotated via a belt 3 or the like. As a result, a pin of the apparatus is fitted in a lead groove 4c of the lead screw. At the same time, a head carrier 8 loading an ink recording head 11a and an ink tank 11 is reciprocated along a guide shaft 14. In this case, an elastic member 7 is set at an end face 4b of the lead screw in a manner to be in touch with the end face 4b. At the moment when recording is finished, the force of intertia acts on the head carrier 8 and the lead screw 4. When the volume in the ink tank 11 is changed, the force of inertia is also changed, resulting in the change of the shifting amount of the elastic member 7. Therefore, the remaining amount of ink is detected from the shifting amount of the elastic member 7.

Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To miniaturize the device and also to improve the performance by simple constitution. SOLUTION: A carrying direction of a disk 401 is changed by a turning operation of a disk carrier mechanism 300, and also the disk 401 is moved to be carried into a position at a prescribed height by an elevator operation, so that carrying speed is enhanced. Since an extra space, etc., are not required for changing the carrying direction of the disk 401, the device can be miniaturized. During the turning operation and the elevator operation of the disk carrier mechanism 300, no impact is given to the disk 401 under carrying and also a chucking member 370 by other members, thus enhancing the safety. Then, for example, since changing of the disks 401 in the magazine 400 can be performed via a mail slot 500, the operability is improved.  Since driving force of the chucking member 370 is given by a ball clutch mechanism 320 of endless constitution, driving force for various operations can be given by a single driving motor.

Abstract: PURPOSE:To decide optimum exposure by estimating the distribution of spectral transmitting density or the distribution of spectral transmissivity based on a few photometry values and using the estimated distribution of the spectral transmitting density or the estimated distribution of the spectral transmissivity. CONSTITUTION:It is assumed that the distribution of the spectral transmitting density is expressed by the linear sum of the distribution of the spectral transmitting density of eight main components. Light transmitted through a film is spectrally split to eight wavelength regions and the photometry thereof is executed (a step 106). Then, a coefficient for expressing the distribution of the spectral transmitting density by the linear sum of the distribution of the spectral transmitting density of eight main components is obtained based on eight photometry values and the distribution of the spectral transmitting density of eight main components. Based on the obtained coefficient and the distribution of the spectral transmitting density of eight main components, the distribution of the spectral transmitting density is estimated (a step 110). Then, the transmitting density which is equal to the transmitting density obtained when the photometry of the image of the film to be printed is executed by a photometry device whose distribution of spectral sensitivity is identical to that of a copying sensitive material is calculated by using the estimated distribution of the spectral transmitting density, the energy distribution of a light source and the distribution of the spectral sensitivity of the copying sensitive material and the exposure for printing the image of the film to be printed on the copying sensitive material is decided based on the calculated transmitting density.
