Abstract

PURPOSE:To promote the operability by enabling a small size tape cassette as well as a standard size tape cassette to be directly inserted into the subject device. CONSTITUTION:A shutter 67 is moved integrally with a small size tape cassette holder 10 by tension springs 81 and 82 and brought into contact with the end parts of guide grooves 73 and 74 of a panel 2 in front of projecting parts 68 and 69, so that an unnecessary part for inserting the small size tape cassette in a tape cassette inserting hole 3 is covered to be concealed. In the case of using the small size tape cassette, when a tape cassette selecting button is pressed, the holder 10 is moved from a position which is not obstructive to the loading operation of the standard size type cassette to a position opposite to the cassette inserting hole 3. Under these circumstances, when the small size tape cassette is inserted, a similar operation to loading the standard size tape cassette is carried out to load this cassette into the device. By this method, the operability particularly is promoted.

Problems to be Solved by the Invention However, with the above configuration, when a standard tape cassette is installed in the device, the adapter for the small tape cassette inserted in the device must be removed from the device.
Must be stored outside the equipment. In addition, when using a small tape cassette, you must first insert the small tape cassette adapter stored outside the device into the device, and then insert the small tape cassette from the small tape cassette insertion slot at the top of the device. There was the troublesome problem of not being able to do so.

SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a magnetic recording and reproducing apparatus which is constructed so that a small tape cassette as well as a standard tape cassette can be directly inserted into the apparatus, thereby improving operability.

Means for Solving the Problems In order to solve the above problems, the magnetic recording and reproducing apparatus of the present invention has a cassette insertion slot into which a standard tape cassette or a small tape cassette smaller than the standard tape cassette is inserted, and a tape cassette insertion slot. a first holding means for holding a standard tape cassette inserted through the opening; a second holding means for holding a small tape cassette inserted from the cassette insertion slot; a tape drive means to be driven; a first holding means at a first position where a standard tape cassette is inserted into the first holding means from a cassette insertion slot; and a second position where a standard tape cassette is mounted on the tape drive means. a first moving means for reciprocally moving the standard tape cassette; a third position for not interfering with the movement of the standard tape cassette by the first moving means; and a fourth position for inserting the small tape cassette into the second holding means from the cassette insertion slot. selectively moving the second holding means to a fifth position for mounting the small tape cassette on the tape cassette drive means, and mounting or detaching the standard tape cassette from the tape drive means by the first moving means; The second holding means is configured to include a second moving means for moving the second holding means to the third position, and a locking means for locking the second holding means at the fourth position.

Effects of the present invention With the above-described configuration, when a standard tape cassette is used, the holder for the standard tape cassette is inserted from the cassette insertion slot, similar to conventional magnetic recording and reproducing devices dedicated to standard tape cassettes. It is only necessary to move the standard tape cassette back and forth between the position where it can be held and the position where it is installed in the device, so simply inserting the standard tape cassette into the cassette insertion slot is enough to load it into the device, and the time required to install it is also the same. It is equivalent to a device dedicated to tape cassettes, and does not impair operability. When using a small tape cassette, pressing the tape cassette selection button moves the small tape cassette holder from a position where it does not interfere with the mounting operation of the standard tape cassette to a position facing the cassette insertion slot. If you insert a small tape cassette into the cassette insertion slot in this state, it will perform the same loading operation as a standard tape cassette, and the small tape cassette will be loaded into the device. Operability can be significantly improved compared to devices that use adapters.

Further, the drive motor 33 rotates and the slide lever 24 moves to the right, but the slide lever 22 cannot move because the standard tape cassette 89 has already been attached. Therefore, the protrusion 27 of the slide lever 24 and the hole 26 of the slide lever 22 are separated, and the biasing force of the tension spring 25 acts on the slide lever 22, thereby pressing the standard tape cassette 89 onto the substrate 4.

The case of taking out a standard tape cassette from the device will be explained.

When you press the cassette eject button 97 provided on the front panel 2,
In the state shown in FIG. 6, the drive motor 33 rotates and drives the cam gear 30 to rotate counterclockwise. Therefore, the standard type tape cassette holder 7 is moved from the position shown in FIG. 6 to the position shown in FIG. 5 by performing the operation opposite to the above-described standard type tape cassette mounting operation. In the state shown in FIG. 5, the user can grasp a part of the standard tape cassette 89 protruding outside the apparatus 1 and take it out of the apparatus.

Next, the case where a small tape cassette is installed in the apparatus will be explained.

When the tape cassette selection button 98 is pressed in the standard tape cassette standby state shown in FIGS. 1 and 2, the drive motor 33 rotates and drives the cam gear 30 to rotate counterclockwise. The cam gear 30 is formed with a second grooved cam portion (not shown) having a stroke as shown in FIG. The fact that the cam gear 30 rotates counterclockwise from the state shown in FIG. 2 means that the rotation angle in FIG.
The second grooved cam part (not shown) has a stroke at 10°, and the slide lever 47 is slidably engaged with the second grooved cam part (not shown) by the cam follower 50.
slides to the right in Figure 2. Slide lever 4
The slide lever 45, which is in contact with the hole 49 of No. 7 and the protrusion 48, also slides to the right in FIG. Rotate to. Therefore, the drive arm 39 that is engaged with the gear 42 and the gear portion 41 rotates clockwise, and moves the small tape cassette holder 10 that is engaged with the protrusion 36 in the groove 40 along the guide groove 11 into the eighth position. Move it to the position shown in the figure. At this time, as shown in Figure 3,

Rotate further counterclockwise from the state shown in the figure. Further rotation of the cam gear 30 in the counterclockwise direction from the state shown in FIG. 12 means that the cam gear 30 further rotates in the negative direction from the rotation angle of -120° in the cam diagram of FIG. The cam portion (not shown) has a stroke. Therefore, the slide lever 47, which is slidably engaged with the second grooved cam portion (not shown) and the cam follower 50, further slides to the right from the position shown in FIG. Then, the slide lever 45, which is in contact with the hole 49 of the slide lever 47, also slides to the right in FIG. As the slide lever 45 moves to the right in FIG. 12, the gear 42 meshing with the rack part 46 of the slide lever 45 rotates counterclockwise, and the drive arm meshing with the gear 42 and the gear part 41 rotates counterclockwise. 39 further rotates clockwise from the position shown in FIG. Therefore, the small tape cassette holder 10 whose protrusion 36 is slidably engaged with the groove 40 of the drive arm 39 is guided by the guide grooves 11 and 12 and holds the small tape cassette 58 when the small tape cassette holder 10 moves to the 12th position. It moves further to the right from the position shown in the figure, and moves to the position shown in the plan view of FIG. At this time, the protrusion 62 of the conversion lever 51
The small tape cassette holder 10 engages with the lid holder 64 for opening the front lid 100 of the standard type tape cassette 89 formed in Figure 3, and moves the small tape cassette holder 10 downward in the guide groove 11, 12 to the position shown in Figure 14. When the small tape cassette 58 is mounted on the device, the switching lever 51 rotates counterclockwise in FIG. 14. Conversion lever 5

The tape cassette can be installed in a magnetic recording/reproducing device simply by inserting the desired tape cassette into the cassette insertion slot of the device, without using a small tape cassette adapter.

Furthermore, by providing the locking means for locking the second holding means in the fourth position, the second holding means is accurately positioned, making it easier to insert the small tape cassette, and The amount by which the tape cassette protrudes from the magnetic recording/reproducing device is also stable, and the amount that can be grasped by hand when taking out the small tape cassette is also constant, allowing for reliable operation.

Further, the first holding means holds the second holding means to the fourth holding means.
By driving the locking means that locks in position, the second holding means can be positioned at the small tape cassette standby position with a simple configuration and a single drive motor.

Furthermore, by making the bottom surface of the standard tape cassette inserted into the first holding means and the bottom surface of the small tape cassette inserted into the second holding means substantially the same, the standard tape cassette and the small tape cassette The cassette can be easily inserted into each holding means by being guided by the lower surface of the cassette insertion opening on the front panel.

Furthermore, when the second holding means moves to the fourth position, it substantially covers the part of the cassette insertion slot where the small tape cassette is not inserted, and also indicates that the small tape cassette is to be used. By providing a cover with a section, the user can visually confirm that the small tape cassette is being used, which reduces erroneous operations and increases the reliability of not inserting unnecessary items or exposing the inside. It has excellent properties and appearance.
