Abstract: Disclosed is a disc insertion preventive device comprising a housing having a disc slot made on its front side, a generally stopper and a swinging mechanism. The stopper comprises a flat plate and front and rear blocking pieces dependent from the opposite lateral edges of the flat plate. The stopper is pivotally fixed to the housing with the front blocking piece directed toward the disc slot of the housing. The swinging mechanism is responsive to absence of a disc in the housing for inclining the stopper with the rear blocking piece down and with the front blocking piece up, thus preventing advance of a disc beyond the descendent rear blocking piece, and is responsive to presence of a disc in the housing for inclining the stopper with the rear blocking piece up and with the front blocking piece down, thus preventing insertion of another disc from the disc slot.

Abstract: The invention provides a recording/reproducing device which records management data unifying front and back sides. A management data input/output processing section reads data from a front side of an inserted recording medium, a management data creation section creates management data on the front side and temporarily stores it in a memory section. After prompting the user to turn over the recording medium, the device checks the turnover of the disk, and reads data on the back side and creates management data. The management data creation section creates unified management data which unifies the management data on the double-side and the unified management data is wrote onto the back side of the recording medium. When writing is completed, the device prompts the user to turn over the recording medium and records, upon recognizing that it is the front side, the unified management data onto the front side.

Abstract: To provide a recording and reproducing apparatus capable of recording data infallibly without being dependent on the copyright protection information. A recording format selected during timer recording operation of a broadcast program by the DVD recording/reproducing unit 5 is compared with a copyright protection information detected by a copyright protection information detecting means 8b, and it is determined whether the selected recording format is suitable for recording the broadcast program, wherein if it is determined that the format is not suitable, the recording format is changed compulsorily to the suitable recording format. Further, if data already exists in the DVD being set, the data is copied to the HDD recording/reproducing unit 6 and the DVD is initialized before recording data, so that the space for recording the broadcast program designated by the user can be ensured.

Abstract: The invention provides a disk reproducing apparatus and a disk reproducing method capable of reducing constrained reproduction by reproducing another type of reproducible data for the portion in which the designated type of data cannot be reproduced. In step S250, it is determined whether there is an error in the reproducing audio data or not, and if there is an error in the reproducing audio data, the procedure advances to step S260. In step S260, it is determined whether there are errors in all the audio data, and if there are errors in all the data, the procedure advances to step S270, whereas if not, the procedure advances to step S310. In step S270, it is determined that audio is not to be output. In step S310 and onward, other reproducible data are reproduced.

In a reproducing device 1 for reproducing a recording medium 2, if an operation of stop position storage means 12c of a microcontroller 12 is instructed by operation means 14 during reproduction of video, the stop position storage means 12c erases the oldest stop position from among stop positions stored in a stop position storage area 13a which is capable of storing a plurality of stop positions of a memory 13 which stores stop position information on positions at which the video is stopped and stores the stop position in a free space area of the stop position storage area 13a resulting from such an erasure, and can thereby store a plurality of stop positions through a simple operation.

Abstract: The invention provides a display device designed to reliably discharge air heated to a high temperature to the outside. Heat from a heating part mounted on a power supply substrate is transmitted to air inside an enclosure and the air heated to a high temperature moves upward by means of natural convection and is discharged through exhaust holes in the upper surface of a back cabinet. As a result of this, outside air is taken in through intake holes in the lower surface of the back cabinet, the outside air pushes up the air inside the enclosure from below and discharges it, and it is possible to thereby prevent the air inside the enclosure from becoming hot and forcibly take in/exhaust air, eliminate the necessity for any air blowing fan and thereby achieve cost reduction.
