Abstract

PROBLEM TO BE SOLVED: To reduce the costs of a device main body by simplifying the structure of preventing the insertion of recording medium when another recording medium is already inserted into the device main body. SOLUTION: Two lid bodies 2 and 3 are attached to a rotary shaft 1. An insertion port 11 is closed by lid body 3 when the rotary shaft 1 is rotated by 90 deg. from the closed state of the insertion port 11 by the other lid body 2, and the rotary shaft 1 is rotated by 90 deg. following the insertion of a recording medium 12a into a main body. Thus, the insertion port 11 is closed by one of the lid bodies 2 and 3, and the incursion of dust or other trash into the main body is prevented. In addition, since the rotational range of the rotary shaft 1 is limited to 90 deg., the insertion of another recording medium 12b is prevented while the recording medium 12a is inserted in the main body.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medium processing apparatus for processing a recording medium such as a video cassette or a mini disk inserted into an apparatus main body, and more particularly, to a mechanism for opening and closing an insertion opening for inserting a recording medium into the main body. The present invention relates to a medium processing apparatus having an improved structure.

[0002]

2. Description of the Related Art Conventionally, media processing such as a video deck or an MD player for recording information on a recording medium such as a video tape or a mini disk (hereinafter simply referred to as MD) or reproducing the recorded information. There was equipment. The medium processing device is provided with an insertion port for inserting a recording medium into the apparatus main body as is well known, and transports the recording medium inserted from the insertion port to a processing position where a write head and a reproduction head are arranged. On the other hand, processing such as recording and reproduction of information is performed.
Further, the medium processing apparatus is provided with a lid that opens and closes the insertion port so that dust such as dust or dirt does not enter the inside of the main body from the insertion port into which the recording medium is inserted.

FIG. 11A is a diagram showing a structure of a mechanism for opening and closing an insertion port in a conventional medium processing apparatus. In this figure, reference numeral 20 denotes a chassis of the apparatus main body;
Reference numeral denotes an insertion port for inserting a recording medium into the apparatus main body, reference numeral 22 denotes a shaft fixed along the upper portion of the insertion port 21, and reference numeral 23 denotes a lid rotatably attached to the shaft 22. Normal,
The insertion slot 21 is closed by a lid 23 as shown in FIG. 11A, so that dust such as dust or dirt does not enter the inside of the main body. Then, as shown in FIG. 11B, when the recording medium 24 is inserted into the inside of the main body from the insertion port 21, the lid 23 pushed by the tip of the recording medium 24 rotates around the shaft 22 toward the inside of the main body. Then, the insertion port 21 is opened. Then, the recording medium 24 enters the apparatus main body from the opened insertion port 21. When the recording medium 24 is inserted into the main body to a certain extent, it is conveyed to a predetermined position inside the main body (a processing position where a write head and a reproduction head are arranged) by a loading mechanism (not shown) (FIG. 11 ( C)). Also, when the inserted recording medium 24 is transported to the processing position inside the main body, the lid 23
It returns to its original position by its own weight, and the insertion opening 21 is closed by the lid 23.

Further, the medium processing apparatus also has a discharge mechanism for discharging the recording medium 24 inserted into the main body to the insertion slot 21. At this time, the lid 23 is pushed against the rear end of the recording medium and rotates outwardly of the main body to open the insertion port 21, contrary to the insertion. Then, the recording medium is ejected from the opened insertion port 21 (see FIG. 11D).

In the above configuration, even if the recording medium 24a is already inserted into the main body (the state shown in FIG. 11C), another recording medium 24b is inserted into the insertion slot 21.
(See FIG. 12 (A)), the cover 21 rotates and the insertion opening 21 is opened.
4b also enters the main body, and the leading end of the recording medium 24b presses the rear end of the previously inserted recording medium 24a (see FIG. 12B). As a result, there is a problem that these two recording media 24a and 24b are damaged, and a mechanism inside the apparatus main body is damaged.

[0006] In order to solve this problem,
When a recording medium is inserted into the main body of the apparatus, a cover for opening and closing the insertion opening is locked to prevent another recording medium from being inserted into the main body of the apparatus (Japanese Patent Laid-Open No. Hei 6-1994). No. 20357, JP-A-8-14
No. 7844) has been proposed.

[0007]

However, the sensor described in Japanese Patent Application Laid-Open No. Hei 6-20357 discloses a sensor for detecting the presence or absence of a recording medium inserted in the main body, and a detection result of the sensor. A mechanism for locking or unlocking the lid that opens and closes the insertion opening by moving the lock plate based on this is necessary.
Japanese Patent No. 7844 discloses an interlocking lever having a complicated structure for switching between locking and unlocking of a lid in conjunction with a loading mechanism for transporting an inserted recording medium to a predetermined position inside the apparatus main body. Was needed. That is, the conventional mechanism for opening and closing the insertion slot for inserting the recording medium has a problem that the configuration is complicated and the cost of the apparatus body is high.

An object of the present invention is to reduce the cost of the apparatus main body by simplifying the configuration for preventing the insertion of another recording medium when a recording medium is already inserted inside the apparatus main body. It is to provide a device.

[0009]

SUMMARY OF THE INVENTION The present invention is directed to a medium processing apparatus for processing a recording medium such as a video cassette or a mini disc inserted into the main body from an insertion port, and is rotatable along one side of the insertion port. With the mounted rotation axis,
Two angles fixed substantially at right angles to the rotation axis, and two lids located outside the two angles and rotatably attached to the rotation axis to open and close the insertion port, An elastic member connected to the two lids and biasing the two lids inward of the two angles, wherein a rotation range of the rotation shaft is limited to about 90 degrees. Have been.

[0010] In this configuration, two angles are fixed to the rotating shaft rotatably mounted along one side of the insertion opening at a substantially right angle, and the two angles are sandwiched between the two angles. The lid is rotatably attached. In addition, since the two lids are urged inward of the two angles by the connected elastic members, they come into contact with the outer surfaces of the angles arranged at a right angle, and are positioned substantially at a right angle. For this reason, when the rotation axis is rotated by 90 degrees in a certain direction from a state where one lid closes the insertion opening, the insertion opening is closed by the other lid.

Therefore, when the recording medium is inserted into the apparatus main body and the rotation shaft is rotated by 90 degrees in conjunction therewith, when the recording medium is not inserted into the apparatus main body, the insertion opening is closed by one lid. When the recording medium is inserted into the main body, the insertion opening is closed by the other lid. When the recording medium is ejected from the apparatus main body, the rotating shaft may be rotated 90 degrees in a direction opposite to the direction in which the recording medium is inserted.

Further, since the rotation range of the rotating shaft is limited to 90 degrees, even if another recording medium is inserted while the recording medium is already inserted in the apparatus main body, the rotating shaft does not rotate. The other lid closing the insertion opening is locked by the angle with which the other lid is in contact, so that another recording medium can be prevented from being inserted into the main body.

The rotating shaft has a pressing portion having a surface substantially parallel to each of the two angles,
Since the plate spring that presses the pressing portion is provided, the state of the rotation shaft is stable when the rotation angle is 90 degrees. Therefore, the rotating shaft can be rotated exactly 90 degrees.

A projection is formed on at least one of the two lids at an end opposite to the rotary shaft. Thereby, the rotation of the lid with respect to the rotation axis becomes smooth, and the possibility of the lid being damaged can be reduced.

Further, by making the colors of the two lids different, it can be visually judged whether or not a recording medium has been inserted into the main body.

FIG. 1 is a perspective view showing the structure of an insertion opening and closing mechanism for opening and closing an insertion opening of a recording medium in a medium processing apparatus according to an embodiment of the present invention. FIG. It is a front view of an opening / closing mechanism. In the figure, reference numeral 1 denotes a rotating shaft rotatably attached to a chassis of the apparatus main body. 2, 3 open and close the insertion port provided in the main body;
The cover is a sheet, and is rotatably attached to the rotation shaft 1. Reference numerals 4 and 5 denote two angles fixed to the rotating shaft 1 at a substantially right angle, and formed with stopper portions with which the lids 2 and 3 abut. The lids 2 and 3 are disposed outside the angles 4 and 5, respectively.
Is mounted on the rotating shaft 1 so as to sandwich the same. Reference numeral 6 denotes a spring for connecting the lids 2 and 3,
Are urged inwardly of the angles 4, 5. further,
The rotary shaft 1 is formed with a rectangular column-shaped pressing portion 7 having a surface parallel to the angles 4 and 5, and the pressing portion 7 is pressed by a plate spring 8 solidified in the main body.

Hereinafter, the operation of the insertion opening / closing mechanism of this embodiment will be described. 3 to 5 are side views of the insertion opening / closing mechanism according to this embodiment. In the drawings, reference numeral 10 denotes a chassis of the apparatus main body, and reference numeral 11 denotes an insertion slot into which a recording medium is inserted. FIG. 3A is a diagram showing a state when a recording medium is not inserted into the apparatus main body, and FIG. 3B is an enlarged view showing a state of the rotating shaft at this time. When the recording medium 12a is not inserted into the main body, the insertion slot 11
The rotation axis 1 attached along the upper side of the
And the pressing portion 7 are in surface contact with each other, and the state is stable. At this time, the angle 4 extends substantially directly below the insertion port 11, and the angle 5 extends outward along the upper surface of the insertion port. As described above, the lids 2 and 3
Since the angles 4 and 5 are sandwiched and connected by the spring 6, the lid 2 is in contact with the outer surface (stopper portion) of the angle 4, and the insertion opening 11 is closed by the lid 2. ing. The lid 3 extends outward along the upper surface of the insertion slot 11 as shown.

Next, when the recording medium is inserted into the insertion slot 11, the lid 2 closing the insertion slot 11 is pushed by the tip of the inserted recording medium 12a, and the main body is pressed against the urging force of the spring 6. It rotates inward (see FIG. 4A). Therefore, the insertion opening 11 closed by the lid 2 is opened, and the recording medium 12a enters the inside of the main body. At this time, the lids 2 and 3 are connected to the recording medium 12a inserted as shown in the figure.
The recording medium 12a slides into the main body in this state. Note that the angle 4 is provided at a position that does not hit the recording medium inserted from the insertion slot 11. Further, when the recording medium 12a pushes the lid 2 into the inside of the main body, the rotating shaft 1 is rotating, and FIG.
As shown in FIG. 7, the leaf spring 8 and the pressing portion 7 are in contact with each other not with a surface but with a line (the leaf spring 8 is in contact with the side of the pressing portion 7).
(See FIG. 4B), the rotating shaft 1 is in an unstable state.

When the rear end of the inserted recording medium 12a is pushed to some extent, the recording medium 12a is transported to a recording / reproducing position (processing position) inside the main body by a loading mechanism (not shown). . At this time, the lid 3 that has been in contact with the upper surface of the recording medium 12a is
The recording medium 12a, which is drawn into the main body by the action of the spring 6, rotates inside the main body so as to follow the rear end of the recording medium 12a.
Further, the rotating shaft 1 is in an unstable state in which the leaf spring 8 and the pressing portion 7 are in contact with each other by a line instead of a surface, and is fixed to the rotating shaft 1 by the lid 3 rotating inside the main body. 5 is pressed, it rotates until it is in a stable state (a state where the leaf spring 8 and the pressing portion 7 are in contact with each other). Here, when the rotation shaft 1 is rotated 90 degrees from the state before the recording medium is inserted, the plate spring 8 and the pressing portion 7 come into a stable state in which they are in surface contact. That is, when the rotating shaft 1 rotates 90 degrees, the rotating shaft 1 enters a stable state in which the rotation stops.

When the rotating shaft 1 is in a stable state, the angle 5 extends from directly above the insertion port 11 to almost directly below.
The lid 3 is pulled by the spring 6 until it comes into contact with the angle 5, and the insertion opening 11 is closed by the lid 3 (see FIG. 5). On the other hand, the lid 2 extends inward along the upper surface of the apparatus main body, and is in contact with a projection 13 formed on the apparatus main body. The angle 4 is in contact with the lid 2.

In the state shown in FIG. 5 in which the recording medium 12a is inserted into the main body, another recording medium 12a is inserted through the insertion slot 11.
When b is inserted into the main body, the tip of the other recording medium 12b hits the lid 3 closing the insertion opening 11, and attempts to push the lid 3 inside the main body. However, as shown in FIG. 5, since the cover 2 is in contact with the projection 13 and the angle 4 is in contact with the cover 2, the rotation shaft 1 cannot rotate any more. Therefore, another recording medium 1
The lid 3 pushed to the tip of 2b cannot rotate inside the main body, and the insertion opening 11 is not opened. That is, it is possible to reliably prevent another recording medium 12b from being inserted into the apparatus main body into which the recording medium 12a is inserted.

The recording medium 12a inserted into the main body can be pushed out of the recording / reproducing position toward the insertion slot 11 by an ejection mechanism (not shown).
At this time, the rear end of the recording medium 12a hits the lid 3 closing the insertion slot 11, and pushes the lid 3 outwardly of the main body. Thereby, the lid 3 rotates around the rotation shaft 1 to the outside of the main body, and the insertion port 11 is opened. Further, when the recording medium 12a pushes the lid 3 to the outside of the main body, the rotating shaft 1 also slightly rotates, so that the leaf spring 8 and the pressing portion 7 shift to a state in which the leaf spring 8 and the pressing portion 7 are in contact with each other with a line (leaf spring). 8 is in contact with the side of the pressing portion 7) (see FIG. 6), and the rotating shaft 1 is in an unstable state.

The cover 2, which has been in contact with the surface of the recording medium 12a, is rotated outward by the action of the spring 6 so as to follow the leading end of the recording medium 12a discharged to the outside of the main body. In addition, the rotating shaft 1 is in an unstable state in which the leaf spring 8 and the pressing portion 7 are in contact with each other by a line, not a surface, and the angle 4 is pressed by the lid 2 rotating outside the main body. (The state in which the leaf spring 8 and the pressing portion 7 are in contact with each other). That is, when the inserted recording medium 12a is ejected, the rotating shaft 1 returns to the state shown in FIG.

As described above, in the medium processing apparatus according to this embodiment, two lids 2 and 3 are attached to the rotating shaft 1 and
From the state where the insertion port 11 is closed by the one lid 2, when the rotation shaft 1 is rotated by 90 degrees, the insertion port 11 is closed by the other lid 3,
The rotation shaft 1 is rotated by 90 degrees with the insertion of the recording medium 12a into the main body. The rotating shaft 1 is rotated by 90 degrees in the direction opposite to the direction at the time of insertion when the recording medium 12a is discharged from the main body. Therefore,
Since the insertion opening 11 is closed by one of the lids 2 and 3, it is possible to prevent dust such as dust and dirt from entering the inside of the main body. Further, since the rotation range of the rotating shaft 1 is limited to 90 degrees, when the recording medium 12a is inserted into the main body, even if another recording medium 12b is further inserted into the main body, the rotating shaft 1 Does not rotate, and the insertion slot 11 is not opened. Therefore, when the recording medium 12a is inserted into the main body, it is possible to prevent the further recording medium 12b from being inserted. In addition, this configuration does not require a sensor or the like for detecting whether a recording medium is inserted into the apparatus main body, and is a very simple configuration as compared with the conventional configuration. For this reason, the cost of the apparatus main body can be significantly reduced.

Further, since the leaf spring 8 is pressed against the quadrangular prism-shaped pressing portion 7 provided on the rotating shaft 1, the recording medium 12a is inserted into the apparatus main body or the recording medium 12a is discharged from the apparatus main body. The rotating shaft 1 can be surely rotated by 90 degrees.

In the above embodiment, the lids 2 and 3 are connected by the spring 6, but may be connected by rubber or another elastic body instead of the spring 6. Next, another embodiment of the present invention will be described. FIG. 7 is a front view of the insertion opening / closing mechanism according to this embodiment, and FIG. 8 is a side view thereof. The difference from the above-described embodiment is that the projections 2a, 3a (ribs 2a, 3a) are provided at the ends of the lids 2, 3 (ends opposite to the rotating shaft 1). As shown in FIGS. 7 and 8, the lid 2 is provided with a projection 2a on the outside thereof, and the lid 3 is provided with a projection 3a on the inside thereof.

When the recording medium 12a is inserted into the insertion slot 11 as shown in FIG. 8A, the recording medium 12a hits the projection 2a of the lid 2 and rotates the lid 2 inside the main body.
Here, since the protruding portion 2a is located relatively far from the rotation axis 1 of the lid 2, the lid 2 can be smoothly rotated. Therefore, the recording medium 12 hitting the lid 2
a and the possibility that the cover 2 hit by the recording medium 12a is damaged can be reduced. Further, since the projection 3a is formed on the inside of the lid 3, the recording medium 1 can be read from inside the main body.
When the recording medium 2a is ejected, the rear end of the ejected recording medium 12a hits the projection 3a, and the cover 3 can be smoothly rotated to the outside of the main body. Therefore, by forming the projection 3a inside the lid 3, it is possible to reduce the possibility that the lid 3 and the recording medium 12a are damaged when the recording medium 12a is discharged from the apparatus main body.

As described above, in this embodiment, the lid 2,
3, the projections 2a, 3a are provided, so that the lids 2, 3 can be rotated more smoothly, and the recording medium 12a hitting the lids 2, 3 or the lid 2 hitting the recording medium 12a. , 3 can be reduced.
Further, when the recording medium 12a is inserted or ejected, the recording medium 12a is held in a state where the lids 2 and 3 are in contact with the upper surface of the recording medium 12.
a slides, and if the cross-sectional shape of the protrusions 2a, 3a is rounded, the lid 2,
Damage due to contact between the recording medium 3 and the upper surface of the recording medium 12 can also be suppressed.

Further, the colors of the outer surfaces of the lids 2 and 3 may be different. In this way, it is possible to determine whether or not the recording medium 12a is inserted into the apparatus main body based on the colors of the lids 2 and 3 that close the insertion opening 11 as shown in FIGS. For example, if the lid 2 is blue and the lid 3 is red, if the lid closing the insertion port 11 is blue, the recording medium 12a is not inserted into the apparatus main body, and if the lid is red, It can be determined that the recording medium 12a is inserted inside the apparatus main body.

[0030]

As described above, according to the present invention, a very simple structure can be used for the apparatus main body without using a sensor for detecting whether or not the recording medium is inserted into the apparatus main body. When a recording medium is inserted, another recording medium can be prevented from being inserted into the apparatus main body. Therefore, the cost of the apparatus main body can be significantly reduced.
