DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a confirmation apparatus for use in a recording / reproducing apparatus using a magnetic disk, a magnetic tape, an optical disk or the like as a recording medium, and confirms whether or not the recording medium is correctly set. 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 mounted on a floppy disk drive (hereinafter referred to as a "disk drive") provided in the camera.
FDD device) to record image information.

The magnetic disk 10 is provided rotatably in a disk pack 12 in which a floppy disk 11 as a magnetic recording medium is formed of a synthetic resin material, and a center core 13 is driven to rotate by a spindle motor. It is 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. The magnetic disk 10 is provided with a shutter 14. When the magnetic disk 10 is housed in the FDD device, the shutter 14 is opened, and the magnetic head comes into contact with the floppy disk 11.

That is, when the magnetic disk 10 is stored in the FDD device, two positioning pins (fixing pins) provided in the FDD device main body are moved to the positioning holes 12.
a, 12b, and the above-mentioned positioning surface portion 12c abuts on a part of the main body of the FDD device to be set in a recording / reproducing state. FIG. 5 shows a state in which the positioning pins 15 protrude into the positioning holes 12a.

Therefore, the positioning pin does not protrude into the positioning holes 12a and 12b, or the positioning surface 12c
Is not in contact with the main body of the FDD device, the recording or reproduction is not performed normally because the magnetic disk 10 is stored in an inclined state.

For this reason, the following various methods are used to confirm whether or not the FDD device sets the magnetic disk 10 correctly.

[0008] The magnetic disk 10 housed in the middle of assembling the parts is strongly pushed by hand, and it is confirmed from the feeling that the positioning by the positioning mechanism is performed.

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

Further, in the FDD apparatus which requires a more accurate position for storing the magnetic disk 10, the recording and reproducing operations are actually performed, and it is determined whether or not the recording / reproducing signal is lost. I was checking the status.

[0011]

The method of confirming by pressing hard by hand is subject to the condition that there are no obstacles (such as built-in parts) on the magnetic disk 10, so that the design and the production process are greatly restricted. In addition, there is a problem that the accuracy differs depending on the person who confirms, which is not realistic.

The method of visually confirming is not general because it is limited to those in which the stored state of the magnetic disk 10 is visible, and lacks accuracy.

In the method of confirming by recording / reproducing, it is necessary to assemble the recording / reproducing mechanism in advance and confirm it afterwards, so that the production process is restricted. In this confirmation, it is determined whether the magnetic disk 10 is actually positioned. Is not a confirmation.

The present invention has been made in view of the above circumstances, and has as its object to develop a confirmation apparatus used in a recording / reproducing apparatus capable of simply and accurately confirming whether or not a stored recording medium is correctly positioned. .

[0015]

In order to achieve the above-mentioned object, according to the present invention, a recording medium is housed in a non-conductive pack having a positioning hole and a positioning surface, and the recording medium is mounted on a conductive device main body. When stored in a recording and playback device,
A confirmation device for use in a recording / reproducing device having a configuration in which a positioning surface portion abuts a part of the device main body and a positioning pin of the device main body protrudes into a positioning hole to position the device in a recording / reproducing state. A confirmation tool having a conductive film formed on the periphery and its positioning surface is provided, and the confirmation tool is stored in the recording / reproducing apparatus. The conductive film around the positioning hole is used as a positioning pin, and the conductive film on the positioning surface is used as the main body of the apparatus. A recording medium setting confirmation device, characterized in that the circuit is formed by contacting the conductive film when each of the recording medium and the recording / reproducing device is in contact with each other. suggest.

[0016]

[Operation] The confirmation tool is stored in the recording / reproducing apparatus. At this time, the positioning pin protrudes into the positioning hole, the positioning surface portion abuts against a part of the device main body, and when the checking tool is set to 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 device body. 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 properly positioned.

When the positioning pin does not protrude into the positioning hole, or the positioning surface does not contact a part of the apparatus main body, and the checking tool is not set at 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, it does not indicate that the recording / reproducing apparatus is normally positioned.

As described above, it can be confirmed from the display of the detection display circuit means whether or not the setting is normally performed.

[0019]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a pseudo disk 20 manufactured as a confirmation tool. The pseudo disk 20 is the same as the conventional magnetic disk 10 and its positioning holes 12 are used.
The conductive films 21a and 21b are provided around the a and 12b, and the conductive film 21c is provided on the positioning surface 12c.

The conductive films 21a, 21b, 21c are formed on the disk pack surface to a thickness of several μm to several tens μm by processing means such as printing, etching, vapor deposition and the like. For the conductive films 21a, 21b, and 21c, the code fastening portions 22a, 22b, and 22c are integrally formed, and the code soldered to each of the code fastening portions 22a, 22b, and 22c is used. It is connected to a detection display circuit described later.

FIG. 2A is an enlarged sectional view of the positioning hole 12a, 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 slight distance X is provided between the conductive film 21a and the hole edge.

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

That is, if the pseudo disk 20 is inclined, the positioning pin 15 does not protrude into the positioning hole 12a, but the tip of the positioning pin 15 may try to protrude slightly into the positioning hole 12a. In such a case,
By providing the distance X, contact of the conductive film 21a with the positioning pin 15 can be prevented.

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

FIG. 3 shows an example of the detection display circuit. As shown, the conductive films 21a and 21b of the pseudo disk 20
21c is connected in parallel to the positive side of the DC power supply 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 a main body of the recording / reproducing apparatus so that the positioning pins 15 and 26 and the positioning surface portion 12c of the pseudo disk 20 come into contact with each other. Part 25 of 25a
Are connected to the negative electrode side of the DC power supply 23.
The positioning pins 15 and 26 are conductive pins integrally provided on the chassis 25.

In this embodiment, when the pseudo disk 20 is set in the recording / reproducing apparatus, the positioning pins 15, 26 enter the positioning holes 12a, 12b, and the positioning surface 12c
Abuts on a portion 25a of the chassis 25, and when a normal recording / reproducing state is established, all of the LEDs 24a, 24b, 24c are turned on.

That is, the conductive film 21a is
Contact, the conductive film 21b contacts the positioning pin 26, and the conductive film 21c contacts the portion 25a of the chassis 25, and the LED
A power supply circuit 24a, 24b, 24c is formed, and these LEDs are turned on at the same time.

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

On the other hand, when the pseudo disk 20 is set, if all the LEDs 24a, 24b, 24c do not light up, it can be understood that the magnetic disk cannot be set normally.

In this case, since the pseudo disk 20 is tilted, either or both of the positioning pins 15 and 26 do not protrude into the positioning holes, or the positioning surface 12c is part 25a of the chassis 25. Not in contact with

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

When the pseudo disk 20 is floating, all of the conductive films 21a, 21b, and 21c are out of contact, so that all of the LEDs 24a, 24b, and 24c remain off.

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

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

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

[0037]

As described above, the checking device of the present invention can check the setting state of the recording medium as long as the internal mechanism for setting the recording medium is provided, so that the design and production process of the recording / reproducing device are restricted. In addition, since it is only necessary to discriminate the display of the detection display circuit means, unlike the confirmation by human touch, a confirmation device with high accuracy is obtained.

Since there is no need to perform recording and reproduction,
A confirmation device that can reduce the confirmation time without troublesome confirmation operation.
