Description

[Detailed description of the invention] "Industrial application field" The invention is provided with a turntable and a leather pickup, for example, a compact disc is mounted on the turntable, the information of the disc is read by the leather pickup, and music is reproduced. Related to disc players.

2. Description of the Related Art Conventionally, there has been a technique of randomly selecting music on a disk based on a free-run (binary) counter output and playing the music randomly.

"Problems to be solved by the invention" In the prior art, when displaying a music selection start period by random music selection operation, it can be effectively displayed by providing a dedicated display, but the manufacturing cost is increased and There was a problem in selecting the installation location of the display.

[Means for Solving the Problems] However, in the present invention, in a disc player provided with a display having a seven-segment body arranged in a horizontal line for displaying time and the like, the same as the seven-segment body arranged in a horizontal line is provided. Each segment at the height position is set as one set, a random music selection operation is started by turning on a start switch, and a light emission operation is started for each segment of each set in order of height. It is.

[Operation] Accordingly, the seven-segment body of the display is operated in a mode other than the number to display the function. Therefore, for example, a new display means is additionally provided to display the head search operation of a song in a random performance of a disc player. Without increasing the manufacturing cost and expanding the display surface, the horizontal line extending across the entire display width of the seven-segment body arranged in a horizontal line moves up and down, so that the display of the cueing operation is separated. It can be easily confirmed even from a place where it is located, and can be properly displayed without being mistaken for other displays such as a level display.

"Example" Hereinafter, an example of the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory view of a main part, and FIG. 2 is an overall view of a disc player. A cartridge (1) containing six compact discs is mounted so as to be freely inserted and removed, a performance start switch (2) and a stop. The switch (3) and the power switch (4) are arranged on the front panel (5). The power switch (4) is turned on, the cartridge (1) is mounted, and the start switch (2) is operated. , The random performance is started, and the random performance is stopped by operating the stop switch (3).

Further, a display (7) having a plurality of sets of seven-segment bodies (6)... For displaying time and the like is provided on the front panel (5), and as shown in FIG. A random performance circuit (8) to be connected is constituted by a microcomputer, and a random selection circuit (9) for randomly selecting and playing a disc and a performance circuit (8) to the display (7) are connected. As shown in the figure, substantially horizontal segments (a)... (G) of the seven segment bodies (6).
.. (D) are configured to emit light in order of height by time division.

This embodiment is constructed as described above. As shown in the flow chart of FIG. 4, when the start switch (2) is operated to perform random play of the disc, the start switch (2) is detected to be turned on, and FIG. (A) (b) (c)
After the segments (a), (d), and (g) are caused to emit light as shown in FIG. 1, after the uppermost horizontal segments (a)... Are emitted almost simultaneously as shown in FIG. (B)
.. And the lower horizontal segments (d)... Are sequentially emitted in a time-division manner as shown in FIG. At the same time, a random music selection operation is performed by the selection circuit (9), and the music recorded on the disk is sequentially played at random, and the random performance of the disk is stopped by operating the stop switch (3).

[Effects of the Invention] As is apparent from the above embodiments, the present invention is applicable to a disc player provided with a display (7) having seven-segment bodies (6) arranged in a row and displaying time and the like. Each segment (a) (g) (d) at the same height position of the seven-segment bodies (6) arranged in a line
, A random music selection operation is started when the start switch (2) is turned on, and the light emission operation of each segment (a)... (G). Since the seven-segment body (6)... Of the display (7) is operated in a mode other than the number to display the function, for example, when displaying the beginning of a song in a random performance of a disc player, It is possible to suppress an increase in manufacturing cost and expansion of the display surface without adding a new display means, and in particular, a horizontal straight line over the entire display width of the seven-segment bodies (6) arranged in a horizontal line. Since the display moves up and down, the display of the cueing operation can be easily confirmed even from a remote place, and also has a practical effect such that the display can be properly displayed without being mistaken for other displays such as a level display. Than it is.
