Abstract: PURPOSE: To obtain magnetic disk equipment being excellent in operability and inexpensive and scarcely having troubles by a simple construction. CONSTITUTION: When a disk cartridge 72 is inserted, a hook pin 79 proceeds into a fixing groove 75, a link 80 rotates counter-clockwise and a pin 82 pushes a lever 83 in the direction of ejection. Being further pressed in, the disk cartridge 72 comes into contact with positioning stoppers 88a and 88b and, at this position, it is held reliably at a prescribed operating position by a spring force of a spring 87. At the time of ejection, the lever 83 is pushed in the direction of insertion of the disk cartridge 72, the link 80 is rotated clockwise through the intermediary of a pin 82 and the hook pin 79 of the link 80 pushes the disk cartridge 72 in the direction of ejection. Then, a roller 84 comes into contact with a slant on the right side of a cam part of the lever 83, the lever 83 is actuated by the spring 87 and made to move in the direction of insertion, the link 80 rotates further clockwise and thereby the disk cartridge 72 is moved in the direction of ejection.

Abstract: PURPOSE:To accurately, easily, and automatically correct influence on both the change of beam landing and picture distortion applied to a cathode-ray tube(CRT) by earth magnetism. CONSTITUTION:A correction current based on the output of a geomagnetism sensor 45 is supplied to a Z axis correction coil 41 and an X-X axis correction coil 42. The geomagnetic component BHcostheta in the direction of Z axis is canceled by corrective magnetic flux generated from the Z axis correction coil 41, and an earth magnetic component BHsintheta in the direction of X axis is canceled by the magnetic flux generated from the X-X axis correction coil 42, then, the drift of the beam landing and that of the picture distortion can be automatically corrected.

Abstract: PURPOSE:To contrive to realize a heat transferring type printing device, with which printed image having uniform density characteristics can be obtained at all times. CONSTITUTION:Ink ribbon is made so as to have nearly uniform reflectance by laser beam. Before the starting of printing, laser beam is irradiated over the ink ribbon under the condition that dye does not luminesce so as to detect the output level of the laser beam, which is best for the ink ribbon, and to start printing at the best output level. By monitoring the strength of the beam reflected from the ink ribbon with a PD 52 during printing and adjusting the output level of the laser beam so as not to change the strength of the reflected beam, the laser beam having the best output level is projected to the ink ribbon during printing at all times. Thus, a heat transferring type printing device, with which printed image having uniform density characteristics is obtained at all times.

Abstract: PURPOSE:To save the number of photodetectors in one at minimum, the number of which have been requested for the number of resolution in a line direction, and to lower cost, by condensing reflected light from a document once through the use of a fluorescent condensing plate, and introducing it to the photodetector. CONSTITUTION:A LED array 2 is provided on the rear plane side of a flat substrate 6, and light from each LED in the LED array 2 is projected on the paper plane 1 of the document through a selfoc lens array 3. When incident light on plate planes of the fluorescent condensing plates 4 and 4' are abutted with fluorescent bodies, the bodies emit the light, and reflection is repeated, and the light is condensed on an end face intersecting orthogonally with the plate plane. The lengthy directions of the fluorescent condensing plates 4 and 4' are arranged so as to be along with the arranging direction of the LED array 2, and are formed in shapes being bent so as to cover the line-shaped part of the paper plane 1. Photodiodes 5 and 5' that are the photodetectors, are mounted so as to receive the light from one end faces 4a and 4a' (4a' and 5' are not shown in figure, because they are hidden) of the fluorescent condensing plates 4 and 4', and the same number of the photodiodes as those of LEDs are not necessary to be provided, and only one photodetector is required at minimum.

Abstract: PROBLEM TO BE SOLVED: To perform speed-variable recording/reproducing for a magnetic disk. SOLUTION: When a rotational number mode setting command is inputted from an I/F 41, a CPU 39 reads a control sequence from a storing means 40 and then controls each section based on the read sequence. Thus, each node SW driving circuit 34 sequentially switch-drives the field winding wires of a pulse motor 1-1 to reach a specified rotational number. In this case, feedback control is performed to reach the specified rational number instructed by the rotational number mode setting command.
