Abstract

PURPOSE:To smoothly execute a transfer by equipping the title device with an extruding lever to regulate the trailing edge of a disk pack under a carrier state and a leading edge regulating member to regulate the leading edge of the disk pack under the carrier state. CONSTITUTION:A pack extruding lever 408 is inserted from a hole 202 for inserting, made to press a rear sidewall 902 of a video floppy VF, and made to carry the video floppy VF in a C direction. When other video floppy VF is selected, third and sixth motors M3 and M6 are driven, and a base 500 at a head fitting side and a base 600 at a regulating board side are turned in F and H directions respectively and widely opened. A second motor M2 is driven in a direction opposite to the above-mentioned direction, and a carrier member 400 is moved in a D direction. Thereafter, a front frame 416 is abutted on a front sidewall 904 of the video floppy VF and is made to transfer this video floppy VF along a fixed substrate 100. Then, an initial state can be obtained by slightly reverse-rotating the second motor M2 again after transferring the video floppy VF up to a position at which the rear sidewall 902 of the video floppy VF is abutted on the bottom surface of the housing part of a holder 200.

When returning the video floppy (VF) to its original holder storage position, the transport member (400) is moved in the direction DTIj in FIG. 3. The front frame (416) of the conveyance member (400>
It comes into contact with the front wall (904) of the bidet style floppy (VF) and sends the video floppy (VF) back in the direction shown in the figure.

In Figure 1, (500) is the head mounting side base;
(600) is the base on the regulation plate side. Regarding the regulation plate (regulation plate), please refer to Japanese Patent Application Laid-Open No. 57-113459 (GLI
B17/32) In the electronic still camera,
It is well known.

(502) is the rotation center axis, and the head mounting side base (
500) is the first rotation axis centered on this rotation center axis (502).
It rotates in the EF direction in the figure. (M3) is the third for this rotation.

) is a second solenoid for moving this regulating plate (610) in the IJ force direction. In addition, this regulation plate (610)
The reason why the magnetic disk (908 in Fig. 5) inside the video floppy (VF) is kept stationary is made to move in the direction of the IJ force, and the disk (908) is moved by the regulating plate (610) and the head (506). This is because the magnetic disk will deform if it continues to be held between the magnetic disks. For this reason, the regulation plate (610)
This is because it is necessary to retreat the magnetic disk to the magnetic disk restriction release position. This is shown, for example, in the article ``Kuchi - Kastill Video System'' on pages 100 to 105 (especially page 102) of the magazine ``Shashin Kogyo September 1962'' published by Shashin Kogyo Publishing Company. There is.

L The above operation will be explained.

The user attaches the holder (200) containing the video clip (VF) to the moving member (300).

The autochanger then operates to play the selected track of the selected video floppy (VF).

First, drive the third and sixth motors (M3) (M6),
Head mounting side base (500) and regulation plate side base (60
0) to the expanded position (initial position e) shown in FIG.

The first motor (Ml) is rotationally controlled to move the moving member (300) in the direction A in the figure so that the selected video floppy (VF) is positioned at a position where it is pushed out by the puncture pushing lever (408). .

The second motor (M2) is driven. This second motor (M
2) is driven by a ohm gear <406) gear (404
) can be transmitted to the conveying member (400) via the rack (402). The conveying member (400) moves along the fixed substrate (10) in the C direction.
0). The bank push-out bar (408) of this conveyance member (400) comes into contact with the rear wall (902> of the video floppy (VF) through the insertion hole (202) of the holder (200), and the video floppy (V
F) is transported in the C direction.

This video floppy (VF) can be transported to the recording/reproducing position as shown in FIG. The driving of the second motor (M2) is stopped.

Drive the 3rd and 6th motors (M3) (M6) in Fig. 1 to
00> in the EC direction in FIG. 1, so that a video floppy (VF) is held between them (500) and (600). At this time, the center hub of the video floppy (VF) is connected to the spindle shaft (506) and the pressing part (608).
) is located between. 3rd and 6th motor (M3) (M
6) Stop the drive.

The first solenoid (606) is driven as shown in FIG. 4 to securely fix the center hub of the video floppy (VF) to the spindle shaft (506).

The spindle motor (M4) is driven to rotate the magnetic disk at 3600 rpm. 2nd solenoid (61
2) to move the regulating plate (610) in the J direction in FIG. 1, and regulating the magnetic disk with this regulating plate (610). The head access motor (M5) allows the head (
508) to the selected track.

The reproduced signal from this head (508) is demodulated and stored in a memory (not shown). After this, the signals in this memory are read out and used, so there is no need for a reproducing operation by the head.

In addition, once storing the reproduced signal in memory in this way,
Japanese Patent Publication No. 59-79691 (HO4N S/783)
is shown. Note that this example is for noise prevention during head access, so it is specifically different from the present case.

In this way, when the data is stored in the memory, there is no need for a playback operation.

Therefore, the second solenoid (G12) is driven in the opposite direction to move the regulating plate (610) in one direction to release the regulation of the magnetic disk. Then, the drive of the spindle motor (M4) is stopped. This state is called stop mode.

After this, when another track of this video floppy (VF) is selected, the spindle motor (M4
), the second solenoid (612) is driven to move the regulation plate (610) in the J direction, and the rad access motor (M5) moves the head (506) to a newly selected track. The playback signal is stored in the memory, and the stop mode is activated again.

After this, when another video floppy (vF) is selected,
The third and sixth motors (M3) (M6) are driven in the opposite direction, and the head mounting side base (500) and the regulating plate side base (600) are rotated and expanded in the FH direction in Figure 1, respectively. Open.

The second motor (M2) is driven in the opposite direction, and the conveying member (400) moves in the D direction. As can be seen from FIG. 3, the front frame (416> is in contact with the front l! (904>) of the video floppy (VF),
) is transferred along the fixed substrate (100). Then, after transporting the video floppy (VF) until the rear side II (902) comes into contact with the bottom surface of the storage section of the holder (200), the second motor (M2) is rotated in the 9-degree reverse direction again as shown in FIG. It becomes the initial state. In addition, if the video floppy (VF) is placed as shown in Figure 1, the video floppy (VF) will fall into the holder (200) due to its own weight.
Therefore, the conveying member (400>) can be stored simply by moving from the position shown in FIG. 3 to the position shown in FIG.

Thereafter, the moving member (300) controls the rotation of the first motor (Ml) so that the newly selected video floppy (VF) is at a position where it is pushed out by the pack pushing lever (408). is moved.

Then, the newly selected video floppy (VF) is withdrawn and played back in the same manner as described above.
