Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a confirmation apparatus used in a recording / reproducing apparatus having a recording medium such as a magnetic disk, a magnetic tape or an optical disk, and confirms whether or not the recording medium is set correctly. It is for doing.

[0002]

2. Description of the Related Art FIG. 4 shows a 2-inch magnetic disk used in an electronic still camera. This magnetic disk is a floppy disk drive device (hereinafter
It is stored in an FDD device) to record image information.

In this magnetic disk 10, a floppy disk 11 which is a magnetic recording medium is rotatably provided in a disk pack 12 made of a synthetic resin material, and a center core 13 thereof is rotationally driven by a spindle motor. It can be recorded and played back.

In such a magnetic disk 10, two positioning holes 12a and 12b are formed on the surface of the disk pack 12.
And a positioning surface portion 12c are provided. A shutter 14 is provided on the magnetic disk 10, and when the magnetic disk 10 is housed in the FDD device, the shutter 14 is opened, and the magnetic head contacts the floppy disk 11.

That is, when the magnetic disk 10 is housed in the FDD device, the two positioning pins (fixing pins) provided in the FDD device body are positioned by the above-described positioning holes 12.
The positioning surface portion 12c is brought into contact with a part of the FDD device body to set the recording / reproducing state. Note that FIG. 5 shows a state in which the positioning pin 15 projects into the positioning hole 12a.

Therefore, the positioning pin does not project into the positioning holes 12a and 12b, and the positioning surface portion 12c
When the disk does not come into contact with the main body of the FDD device, the magnetic disk 10 is tilted and stored, so that the recording or the reproduction is not normally performed.

Therefore, whether or not the FDD device sets the magnetic disk 10 correctly is confirmed by the following various methods.

The magnetic disk 10 stored in the process of assembling the parts was strongly pressed by hand to confirm whether or not the positioning mechanism could perform the positioning.

Further, in the case where the storage state of the recording medium can be seen, it was visually confirmed whether or not the magnetic disk 10 was correctly positioned.

Further, in the FDD device which requires a higher degree of accuracy in the storage position of the magnetic disk 10, the recording / reproducing operation is actually performed, and it is determined whether or not there is a loss in the recording / reproducing signal, and the magnetic disk 10 is stored. I was checking the condition.

[0011]

The method of confirming by pushing hard with a hand is subject to a large restriction in the design and production process because there is no obstacle (such as a built-in component) on the magnetic disk 10. Another problem is that there are individual differences in accuracy depending on the person who confirms, which is not realistic.

The method of visually confirming is not general because it is limited to the one in which the stored state of the magnetic disk 10 can be seen, and is not accurate.

The method of confirming by recording / reproducing requires assembling the recording / reproducing mechanism in advance and then confirming it. Therefore, there is a restriction on the production process. In this confirmation, whether or not the magnetic disk 10 is actually positioned is determined. It does not confirm.

In view of the above situation, it is an object of the present invention to develop a confirmation device for use in a recording / reproducing device capable of easily and accurately confirming whether or not a stored recording medium is correctly positioned. .

[0015]

In order to achieve the above object, according to the present invention, a recording medium is housed in a non-conductive pack having a positioning hole and a positioning surface portion, and the recording medium is a main body of a conductive device. When stored in a recording / playback device,
A confirmation device used in a recording / reproducing device having a structure in which a positioning surface portion abuts a part of the device body and a positioning pin of the device body is inserted into the positioning hole to position in a recording / reproducing state. A confirmation tool in which a conductive film is formed on the periphery and its positioning surface portion is provided, and the confirmation tool is housed in a recording / reproducing apparatus. The conductive film around the positioning hole serves as a positioning pin, and the conductive film at the positioning surface portion serves as the device main body. A recording medium set confirmation device characterized in that a circuit is formed by contact of a conductive film when each of the parts is contacted, and a detection display circuit means for displaying that the recording / reproducing device is in normal positioning is provided. suggest.

[0016]

[Operation] The checking tool is stored in the recording / reproducing device. At this time, the positioning pin protrudes into the positioning hole, the positioning surface portion abuts against a part of the main body of the apparatus, and when the confirmation tool is set at a normal position, the conductive film around the positioning hole contacts the positioning pin, and The conductive film on the positioning surface contacts a part of the main body of the device. As a result, the detection display circuit means forms a circuit by the contact of the conductive film, and indicates that the recording / reproducing apparatus is normally positioned.

When the positioning pin does not protrude into the positioning hole, or the positioning surface does not abut on a part of the main body of the apparatus, the checking tool cannot be set in a normal position.
The conductive film around the positioning hole and the positioning pin are not in contact with each other, and the conductive film on the positioning surface is not in contact with a part of the apparatus main body. As a result, since the detection / display circuit means does not form a circuit, the recording / reproducing apparatus does not indicate that the recording / reproducing apparatus is normally positioned.

In this way, it can be confirmed from the display of the detection display circuit means whether or not it is normally set.

[0019]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will now be described with reference to the drawings. FIG. 1 shows a pseudo disk 20 manufactured as a confirmation tool. This pseudo disk 20 is the same as the conventional magnetic disk 10, and its positioning hole 12 is used.
The conductive films 21a and 21b are provided around a and 12b, and the conductive film 21c is provided on the positioning surface portion 12c.

The conductive films 21a, 21b, 21c are formed on the surface of the disk pack to have a thickness of several .mu.m to several tens of .mu.m by a processing means such as printing, etching and vapor deposition. Then, with respect to these conductive films 21a, 21b, 21c, the code fastening portions 22a, 22b, 22c are integrally formed, and the cords soldered to the respective code fastening portions 22a, 22b, 22c are attached. It is connected to a detection display circuit described later.

FIG. 2A is an enlarged sectional view of the positioning hole 12a portion, and FIG. 2B is an enlarged front view of the same portion.
As can be seen from these drawings, the conductive film 21a is provided in a ring shape on the outer periphery of the positioning hole 12a, but a small distance X is provided between the conductive film 21a and the edge of the hole.

By providing this distance X, the conductive film 21a does not come into contact with the protruding portion 15a of the positioning pin 15 but comes into contact with the step portion 15b of the pin 15.

That is, if the pseudo disk 20 is tilted, the positioning pin 15 does not project into the positioning hole 12a, but the tip of the positioning pin 15 may try to project into the positioning hole 12a to some extent. In such cases,
By providing the distance X, it is possible to prevent the conductive film 21a from coming into contact with the positioning pin 15.

The conductive film 21b also has a positioning hole 12b.
A distance X is provided between the edge of the hole and the edge of the hole.

FIG. 3 shows an example of the detection display circuit. As shown in the figure, the conductive films 21a, 21b of the pseudo disk 20,
21c is connected in parallel to the positive electrode side of the DC power source 23, and each parallel circuit has an LED 24 for display.
a, 24b and 24c are connected.

The negative side of the DC power source 23 is connected to a chassis 25, which is the main body of the recording / reproducing apparatus, so that the positioning pins 15 and 26 come into contact with the positioning surface 12c of the pseudo disk 20. 25a part of 25
And are connected to the negative electrode side of the DC power supply 23.
The positioning pins 15 and 26 are conductive pins provided integrally with the chassis 25.

In this embodiment, when the pseudo disk 20 is set in the recording / reproducing apparatus, the positioning pins 15 and 26 project into the positioning holes 12a and 12b, and the positioning surface portion 12c.
When a part of the chassis 25 comes into contact with a part 25a of the chassis 25 to bring about a normal recording / reproducing state, all the LEDs 24a, 24b, 24c are turned on.

That is, the conductive film 21a is positioned by the positioning pin 15.
, The conductive film 21b contacts the positioning pin 26, the conductive film 21c contacts the part 25a of the chassis 25, and the LED
Power supply circuits 24a, 24b, and 24c are formed, and these LEDs are turned on at the same time.

From this, it is understood that the recording / reproducing apparatus can normally set the magnetic disk by confirming that all the LEDs are turned on.

On the other hand, when the pseudo disk 20 is set, it can be seen that the magnetic disk cannot be normally set unless all the LEDs 24a, 24b and 24c are turned on.

In this case, since the pseudo disk 20 is tilted, either or both of the positioning pins 15 and 26 do not project into the positioning hole, or the positioning surface portion 12c has a portion 25a of the chassis 25. Is not in contact with.

Therefore, the conductive films 21a, 21b, 21
Any one or two of c becomes non-contact, and L
One or two of the EDs 24a, 24b, and 24c remain off.

When the pseudo disk 20 is lifted up, all the conductive films 21a, 21b and 21c are not in contact with each other, so that all the LEDs 24a, 24b and 24c remain off.

From this fact, the LEDs 24a, 24b, 2
If even one of 4c is turned off, it means that the magnetic disk is a recording / reproducing apparatus that cannot be normally set.

In the above-mentioned embodiment, the pseudo disk 20 is manufactured and used as a checking tool, but a checking tool can be similarly made for a magnetic tape, an optical disk, etc. to check the recording / reproducing apparatus.

Since a recording medium such as a floppy disk is not used directly as the checking tool, only a pack of recording medium may be used and the conductive film may be provided on this pack.

[0037]

As described above, the checking device of the present invention can check the set state of the recording medium as long as the internal mechanism for setting the recording medium is prepared, so that the design and production process of the recording / reproducing device are restricted. In addition, the confirmation device with high accuracy can be obtained because only the display of the detection display circuit means is different from the confirmation by the touch of the human hand.

Further, since it is not necessary to record / reproduce,
This is a confirmation device that can shorten the confirmation time without any trouble in the confirmation operation.
