Abstract
Abstract A disk player for use of playback of both of the single body of a digital optical disk and another digital optical disk encased in a cartridge by a single player. The disk player comprises a disk tray which is mounted on a main chassis and adapted to make its reciprocating movement in the fore-and-aft direction of the player to carry the single body of the disk to a predetermined position in the player. A cartridge carrier is mounted on a sub-chassis connected to and located above the main chassis and makes its reciprocating movement in the fore-and-aft direction to carry the cartridge encasing therein the disk to another predetermined position in the player. A mechanical chassis is tiltably connected to and located below the main chassis and movable upwardly and downwardly. A turntable is rotatably mounted on the mechanical chassis and driven by a motor supported to the mechanical chassis. Either one of the disks carried at the predetermined position is mounted on the turntable to be played back. An optical pickup is movably mounted on the mechanical chassis to pick a digital optical signal from the surface of the disk on the turntable.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
174 words
An apparatus for carrying out at least one of recording signals in and reproducing signals from one of both a naked disk and a disk encased in a cartridge, the disk being a disk shaped recording medium, the apparatus comprising: a disk tray for receiving the naked disk at a first position and to carry the naked disk to a second position at which loading of the naked disk is completed; a cartridge carrier for receiving the cartridge at a third position and carrying the cartridge to the second position at which loading of the cartridge is completed chucking means for chucking the naked disk at the second position, the chucking means selectively taking a first state and a second state, the naked disk being chucked by the chucking means at the first state; a turntable for driving one of the naked disk at the second position and the disk in the cartridge at the second position; and means for controlling the chucking means to selectively take the first state and the second state.
Claim 2
Independent Claim
174 words
An apparatus for carrying out at least one of recording signals in and reproducing signals from one of both a naked disk and a disk encased in a cartridge, the disk being a disk shaped recording medium, the apparatus comprising: a disk tray for receiving the naked disk at a first position and to carry the naked disk to a second position at which loading of the naked disk is completed; a cartridge carrier for receiving the cartridge at a third position and carrying the cartridge to the second position at which loading of the cartridge is completed chucking means for chucking the naked disk at the second position, the chucking means selectively taking a first state and a second state, the naked disk being chucked by the chucking means at the first state; a turntable for driving one of the naked disk at the second position and the disk in the cartridge at the second position; and means for controlling the chucking means to selectively take the first state and the second state.
Claim 3
Dependent Claim
47 words
An apparatus according to claim 1, wherein the controlling means selectively puts the chucking means into the first state in relation to loading of the naked disk at the second position and into the second state in relation to loading of the cartridge at the second position.
Claim 4
Dependent Claim
24 words
An apparatus according to claim 2, wherein the chucking means includes a chucking member which contacts with the naked disk at the second position.
Claim 5
Dependent Claim
17 words
An apparatus according to claim 3, wherein the chucking member is movably mounted on the cartridge carrier.
Claim 6
Dependent Claim
45 words
An apparatus according to claim 3, further comprising means for slidably moving the chucking member together with the cartridge carrier so that the chucking member is movable between two positions which correspond respectively to the first state and the second state of the chucking means.
Claim 7
Dependent Claim
24 words
An apparatus according to claim 5, wherein the cartridge carrier includes a holding device for holding the cartridge at the third position, when actuated.
Claim 8
Dependent Claim
48 words
An apparatus according to claim 6, further comprising a casing encasing therein the disk tray, the cartridge carrier, the chucking means, the turntable and the controlling means, wherein at least a part of the cartridge is inserted into the casing when the cartridge is at the third position.
Claim 9
Dependent Claim
72 words
An apparatus according to claim 7, wherein the controlling means includes first detecting means for detecting the actuation of the holding device, second detecting means for detecting the completion of loading of the cartridge at the first position, and a motor for moving the cartridge carrier together with the chucking member, when driven, the motor being driven in response to the detection of the first detecting means and the second detecting means.
Claim 10
Dependent Claim
79 words
An apparatus according to claim 1, further comprising a shutter opening-closing lever pivotally movably mounted on a stationary member and selectively movable between one position to open a shutter of the cartridge and another position to close the shutter, at least a part of the disk being exposed when the shutter is opened, and means for controlling the shutter opening-closing lever to selectively take the one position or the another position in relation to movement of the cartridge carrier.
Claim 11
Dependent Claim
28 words
An apparatus according to claim 9, wherein the shutter opening-closing lever has a cam follower which is movably associated with a cam surface formed on the cartridge carrier.
Claim 12
Dependent Claim
67 words
An apparatus according to claim 1, wherein the disk tray is slidably movable in a first direction to carry the naked disk from the first position to the second position, and the cartridge carrier is slidably movable in a second direction to carry the cartridge from the third position to the second position, the first direction and the second direction being horizontal and parallel with each other.
Claim 13
Dependent Claim
69 words
An apparatus according to claim 7, further comprising a first chassis encased in the casing, and wherein the disk tray is slidably movably mounted on the first chassis, a second chassis encasing in the casing and connected to the first chassis, the second chassis being disposed vertically spaced from the first chassis to form a two-stage chassis structure, the cartridge carrier being slidably movably mounted on the second chassis.
Claim 14
Dependent Claim
16 words
An apparatus according to claim 12, wherein the first chassis is located below the second chassis.
Claim 15
Dependent Claim
50 words
An apparatus according to claim 13, further comprising a third chassis which is pivotally connected to the first chassis to be tiltable relative to the first chassis in relation to a movement of the disk tray and of the cartridge carrier, the turntable being rotatably mounted on the third chassis.
