A voice recording-reproduction apparatus including a microphone, speaker, voice recording-reproduction circuit, recording medium, key input device and control circuit. The circuit is adapted to prepare a plurality of folders on the recording medium and to perform a data reading and processing operation for predetermined one of the folders in each mode. When a reproduction key of the key input device is depressed and if no data is recorded in the folder to be used in the mode at the time of the depression, the control circuit checks whether or not data is recorded in one of the other folders. When one of the folders is found to have data recorded therein, the control circuit sets the voice recording-reproduction circuit in a mode in which the folder is to be used for data reading and processing, and gives a reproduction command to the circuit.

Data reproduction circuit and voice recording reproduction apparatus comprising the circuit

A disk playback device has an opening-closing slide for moving a tray between a stacker and a disk discharge position, and a gear train for horizontally moving the tray between the stacker and a loading completed position. The device further has a first and second slide members for raising or lowering the tray as opposed to an optical head base after the tray is brought to the loading completed position by the gear train, and third slide member for raising or lowering the slide as timed with the ascent or descent of the tray. With the tray brought to the position of the head base, the third slide member further slidingly moves to raise the slide to couple the slide with another tray within the stacker.

Disk playback device with changer allowing playback of one disk while

A chassis has rotatably mounted thereon a magazine for accommodating a plurality of disks as positioned upright. A playback portion and an insertion-discharge portion are arranged respectively inside and outside the magazine radially thereof. Roller units for holding and transporting the disk are provided between the insertion-discharge portion and the magazine and between the magazine and the playback portion, respectively. The roller units are coupled together by a train of gears and driven by a motor M3 to rotate in directions opposite to each other. Control apparatus is disposed within the device main body for energizing the motor M3 for a specified period of time before the magazine is rotated to rotate the roller units in directions to draw the disk into the magazine.

Disk playback device and method of controlling the device

A disk playback device comprises a magazine having a plurality of disk spaces for accommodating disks in an upright position, and an inlet-outlet portion provided externally of the magazine for permitting the disk to pass therethrough into the magazine from outside a device main body. Sensors for detecting loading of the disk into the magazine are disposed beside a path of travel of the disk and connected to a processor for storing information as to presence or absence of the disk in each of the disk spaces. The device main body has an automatic loading mode wherein an empty disk space having no disk accommodated therein is searched for based on the information stored in the processor as to presence or absence of the disk, the magazine is rotated to position the empty disk space as opposed to the inlet-outlet portion and the operation to search for an empty disk space is repeated again after completely loading a disk into the empty disk space.

Disk recording-playback device and disk loading or unloading method

A control system for a disc playing device which facilitates selection of playing of discs by assigning identification codes comprising consecutive numbers to all disc holding grooves of a magazine. A memory of a microcomputer has a first storage area for storing the identification code of the magazine groove positioned as opposed to a disc insertion-discharge portion or playing portion, and a second storage area for storing the identification code of the groove accommodating the disc to be played. The direction of rotation of the magazine is determined by an arithmetic procedure based on the two identification codes stored in the first and second storage areas and on the difference in position between the insertion-discharge portion and the playing portion around the center of the magazine.

Control system for disc playing device

A magazine controlling method is disclosed for smoothly stopping a disk storing magazine. According to the method of the invention, the rotational speed of the disk storing magazine in rotation is reduced upon the magazine reaching a position a small distance short of a predetermined stop position, and the magazine is then stopped at the predetermined stop position.

Method for controlling a rotatable optical disk storing magazine

A framework of a wooden building has a pair of vertically extending pillars formed on opposite sides thereof with longitudinal grooves and a wall panel mounted between the pillars, having its side edges inserted in the grooves in the pillars. A diagonal pillar formed in the opposite sides thereof with grooves may be provided between the vertical pillars to support two triangular wall panels. A fitting such as a window sash may be mounted between the pillars so as to be sandwiched between upper and lower wall panels.
