Abstract

PURPOSE:To improve the operability by indicating cassette tapes stored in a tray and indicating the cassette tape being in course of recording/reproducing or loading. CONSTITUTION:First, a control circuit 9 lights cassette presence/absence indicat ing means id2 corresponding to storage parts of a tray, where cassette tapes are stored, by a cassette presence/absence detecting means 3. When a cassette is selected by cassette selecting means SB1 to SB6, a cassette transporting means 6 is controlled to load the cassette, and a cassette indicating means Id1 is flickered by the output of a driving detection encoder 4 of the means 6. When loading of the cassette is terminated, the means Id1 is lit and the means Id2 is extinguished. Thus, the cassette tape being in course of recording/ reproducing or loading is indicated to improve the operability.

Description

Detailed Description of the Invention [Field of Application in Industry-1] The present invention is a method for selecting one of a plurality of cassette tapes arranged on one ray and transferring it to a tape drive means for recording. The present invention relates to a display device for displaying which cassette is in which state using a display means in a cassette changer that performs playback.

(Prior Art) Conventionally, compact disc autochangers have been common as this type of autochanger, but this autochanger has a display that shows how many compact discs are being played and which track is being played. However, in states other than playback, there was no display showing how many compact discs were stored, or whether a compact disc was being loaded.

[Problem to be solved by the invention]

As mentioned above, in conventional O-I changers, it is not known how many discs (cassette tapes) are stored, so when the operator selects a disc that is not on the tray ( cassette tape), and since no display appears when loading a disc, it is difficult to judge whether or not the loading operation is actually being performed, which can be confusing. There were other problems.

[Purpose of the invention]

The present invention is intended to solve the above-mentioned problems, and its purpose is to display the cassette tapes stored in the tray, display which cassette tape is being recorded or played back, and display the cassette tape being loaded. It is an object of the present invention to provide a display device for a cassette changer that can eliminate operational errors and confusion on the part of the operator by displaying the following.

[Summary of the Invention] The present invention aims to achieve the above-mentioned object, and its gist is to determine in which position on the tray the cassette tape is stored, and which cassette tape is stored in the tray. Was it transferred and attached to the tape drive means?
and a display device for a cassette changer in which display means indicates whether the tape is being transferred from the tray to the tape drive means.

5 is an encoder that detects the operating state of a cassette transfer means 5, which will be described later, from the tray 2; 5 is a cassette presence/absence detection means that detects that a cassette tape is mounted on the circuit drive means 7, which will be described later; 6 is a cassette from the tray 2, which will be described later. cassette transport means 7 for transporting the cassette tape to the drive means 7;
Reference numeral 8 indicates a cassette drive means for driving the cassette tape transferred by the cassette transfer means 6 for playback, recording, fast forwarding, rewinding, etc., 8 a tray drive means for protruding or storing the tray 2 from within the apparatus main body 1; is a control circuit such as a microcomputer that performs operations as shown in the flowcharts shown in FIGS. 3 and subsequent figures.

Next, the operation will be explained based on the above-described configuration with reference to the flowcharts from FIG. 3 onwards.

FIG. 3 is a flowchart for displaying whether or not a cassette tape is stored in tray 2, which is cassette selection means. In FIG. 3(a), the flowchart of each block portion 83 to S8 indicated by virtual lines is step 7 Sa and step sb shown in FIG. 31q(b).

First, the control circuit 9 monitors whether or not the tray 2 is in an open state (step s1), and if it determines that it is in an open state, the control circuit 9 shifts to the loading display shown in FIG. 4 without displaying the storage state of the cassette.

Also, step S1. When it is determined that the tray 2 is not in the open state, the assist l- of the tray 2 (monitors whether or not it is in the moving state) is determined to be in the moving state, and displays the storage state of the cassette I. The display shifts to the rotating display shown in FIG. 4 without changing the display.

When the control circuit 9 determines that the Louis 2 is in transit, it determines whether or not the cassette presence detection means 3 disposed in the first storage section of the tray 2 is turned on based on the cassette tape (step Sa). As a result of this judgment, if the cassette tape presence/absence detection means 3 is on, the first case I/presence display means 1d2, which indicates that a cassette tape is stored, is lit (step Sb). Further, if the cassette presence/absence detection means 3 is off, step S
Skip step b and proceed to the next step S4. This step S
In step 4, the same operation as in step knob S3 is performed, and when the cassette presence/absence detection means 3 detects a cassette, the second cassette presence/absence display means 1d is turned on]. below,
A similar operation is performed for all six storage sections of the tray 2 (step S8), and the cassette presence/absence detection means 1d2 corresponding to the section where the cassette tape is present is turned on, and when all operations are completed, FIG. Shift to the loading display.

Next, rope ink display will be explained with reference to FIG. The blocks (steps 317 to 522) indicated by virtual lines in FIG. 4(a) perform the same operations as the flowcharts hs] and a-3ld shown in FIG. 4(b).

When the cassette stored in the first storage section of the tray 2, which is the cassette selection means, is selected by the cassette selection means SB, the control circuit 9 controls the cassette transfer means 6 to move the first cassette I.・Loading is performed. Then, the control circuit 9 monitors whether or not the first cassette is being loaded. )
, monitors the output from the drive detection encoder 4 of the cassette transfer means, that is, monitors whether or not the cassette transfer means 6 is in operation (step 5la). When the control 'fσ circuit 9 receives the output from the encoder 4, it blinks the cassette display means 1d (step 5ob). If it is determined in step Sla that the transfer of the cassette by the cassette transfer means 6 has been completed, the cassette display means ld is turned on (step 5lc).

On the other hand, the control circuit 9 is operated in step S1b and step Slc.
When receiving the output from the above circuit presence display means 1d,
2 is turned off (step S1.d).

Further, in step Sll, if the cassette selection means SB is not operated, the control circuit 9 monitors whether or not the second cassette is being loaded (step 5L2); if the cassette transfer means SB2 is operated, the control circuit 9 monitors whether or not the second cassette is being loaded. For example, the operation shown in FIG. 4(b) is performed in step S18. Thereafter, in the same manner, the control circuit 9 repeatedly checks whether or not a loading command for the sixth cassette has been issued (step 516). If the command has been issued, the control circuit 9 performs the operations shown in FIG. 4(b) in steps 18 to 22. This will be done at

〔Effect of the invention〕

As described above, the present invention is capable of determining in what position the cassette tape is stored in the 1-ray, whether the cassette tape is transferred from the 1-ray and loaded onto the tape drive means, and whether the cassette tape is transferred from the 1-ray and loaded onto the tape drive means. Since the display means indicates whether the transfer is in progress to the drive means, it has the following effects: 1. It is possible to eliminate operational errors and confusion on the part of the operator.
