摘要： PURPOSE: To shorten moving distance of a pickup part as compared with such a structure that plural pickup parts are individually moved by piling at least more than one pickup part out of the plural pickup parts and moving this piled layer. CONSTITUTION: When the pickup part 200 is selected, and a command is issued to perform recording and reproducing by this pickup part, a moving device is controlled by operating control circuits 105 and 205 to lift the pickup parts 100 and ZOO in the direction of (a) in keeping their piled layer. Thus the pickup part 200 can be moved to a position capable of drawing out a disk 1c, and hence the disk 1c can be recorded and reproduced. Then, when the pickup part 100 is selected, and a command for its recording and reproducing is issued, the pickup part 100 is controlled to be separated from the pickup part 200 and also to be lifted in the direction of (a) by operating the control circuit 105. Thus, the disk 1c is drawn out and is recorded and reproduced by the pickup part 100.

摘要： PROBLEM TO BE SOLVED: To reduce a size of cartridge by providing subsequently a turn table loading aperture and recording/reproducing aperture and then setting the shortest distance up to the turn table loading opening/closing aperture from the rotation center longer than the recording/reproducing aperture width. SOLUTION: A small size disk 1b comprised in a disk cartridge 11 is partly exposed from a recording/reproducing aperture of a cartridge aperture 10 within a recording/reproducing apparatus and a shutter 12 covers the aperture 10 at the outside of apparatus. The shutter 12 is simply composed of a sheet of plate and it is opened and closed by right and left sliding caused by elasticity of coil springs 13a, 13b. The right and left width of the loading aperture provided through the turn table is defined as 2Wj, while the right and left width of the recording/reproducing aperture as 2Wi. Here, the setting is made to satisfy the condition Wj>=Wi. Thereby, when the shutter 12 is slid to the right or left, an allowance area is generated against the lateral width Wk of the disk cartridge 11 and the disk cartridge loading reference surface can be provided to this allowance area.

摘要： PROBLEM TO BE SOLVED: To attain the insertion and ejection of a disk cartridge without using the energizing means such as a spring, etc., when the disk cartridge is loaded, by making a shutter move in the direction to open an opening part in such a manner that a shutter moving means is linearly moved while bringing into contact with the shutter. SOLUTION: A shutter opening/closing mechanism 6 is provided with a guide groove 5 for controlling a shutter opening/closing pin 4 or the moving direction of the shutter opening/closing pin. The shutter opening/closing pin 4 is shaped so that the tip is columnar and also a chamfer is provided on a part thereof, while a contact part 3 to be in contact with the shutter opening/closing pin, 4 is provided on the shutter 2. When the disk cartridge 1 is inserted to the disk device, the contact part 3 is brought into contact with this shutter opening/ closing pin 4, and when the disk cartridge 1 is furthermore inserted, the shutter opening/closing pin 4 and the contact part 3 are connected and not separated during the loading operation of the disk cartridge 1.

摘要： PURPOSE:To improve the operability by providing a cassette inserting hole in one place on a VTR and automatically carrying a cassette into its corresponding mechanism in accordance with a kind of the inserted cassette. CONSTITUTION:A VHS mechanism, an 8mm mechanism and a common circuit (signal processing and servo circuit) are built in the device. Then, when a cassette is placed on a tray, what kind of the cassette is detected by a tape cassette detecting means. Its detected signal is transmitted to a system control means. Which mechanism should carry the cassette is decided, and then a cassette carrying means is immediately operated by this control means. When the cassette is loaded into its objective mechanism, a completion signal is transmitted by a cassette loading detecting means to a system control means. A signal of the system control means is transmitted to a circuit control means, where an optimum constant is set for operating under its system by the system control means.

摘要： PROBLEM TO BE SOLVED: To keep disk information within a disk holder even when disk cartridge is changed by arranging a removable disk holder to a small size disk cartridge and then providing, to the disk holder, a label area which can realize write or erase operation of necessary information. SOLUTION: A removable disk holder 5 is arranged to a disk cartridge body 1a of a disk cartridge 17a. A label area 30 which can realize free writing of necessary information to a disk 4 is provided to the disk holder 5. When the disk holder 5 is removed from the disk cartridge 1a, a holder arm provided at the disk holder 5 can hold the disk 4 to take out the disk 4. Thereby, at the time of moving the disk 4 from the disk cartridge, the information of disk 45 held by the disk holder 5 can also be moved simultaneously to easily check the contents of disk 4 via the disk holder 5.

摘要： PURPOSE:To improve operation convenience by opening a lid when a cassette is not in existence, ejecting the cassette when the cassette is in existence but a tape is not traveled and emitting light and a sound from a warning means when the cassette is in use. CONSTITUTION:When the cassette is made to approach a VTR 1 by hand, this approach is detected by a detecting means 4 using infrared rays, supersonic waves and magnetic force lines. When another cassette is housed in the VTR 1 under a tape stopping mode, a protective member 6 is moved downward to eject the cassette. When another cassette is already housed in the VTR 1 at the time of inputting a signal of the means 4 to a control means 2, whether the tape is travelling or stopped is moreover discriminated. When the tape is under traveling, a warning is issued. When the tape is in stopped state, the cassette housed in the VTR 1 is ejected. If this tape is desired to be replaced with other one under this tape traveling mode, a tape traveling stopping operation is performed by hand to cope with this action.
