Abstract

PURPOSE:To perform the stabilized opening and closing of a cassette cover by providing the projection part to regulate the fall to the inner side of a holder on the cover opening member provided on the side face of a cassette holder. CONSTITUTION:A cover opening member 17 is provided rotatably on the rotary shaft 18 of the side face of a cassette holder main body 8, rotated by a pin 19 provided on a frame 10 and made so as to open the cover of a cassette 2. The projection part 17a preventing the fall to the holder inner side is formed on the cover opening member 17. Consequently the cover opening member 17 does not fall to the holder inner side at the fitting time of the cassette 2 and the interference with the cassette 2 is prevented. The stabilized opening and closing of the cassette cover can be performed by executing a simple work only.

Description

Detailed Description of the Invention [Industrial Application Field 9.1J1 is for moving a cassette holder that holds a cassette containing a tape-shaped recording medium from a cassette insertion position to a fully loaded position and back. This invention relates to a cassette mounting device that moves.

[Prior Art] In conventional cassette holders used in magnetic recording and reproducing devices (hereinafter referred to as VTRs), the cassette holder must be lowered (
A member is provided for opening the rotating lid provided at the cassette opening when the cassette is moved down. This lid opening is done by a member, or by a fixed bolt provided on the frame of the cassette loading device, and when some external force is applied to the cassette holder when the cassette holder is brought down, the amount of force applied by the fixed member changes. However, there is a problem in that the cassette awn does not open and the cassette falls down or interferes with the cassette body.

That is, in a cassette loading device in which the user presses the cassette holder in the direction to complete loading the cassette, the direction of the force when pressing is not certain. For example, in order to open the rotary lid of the cassette, the lid is opened by pressing a suppressing part provided at the end of the lid, and when considering a structure in which the rotary lid is opened, the cassette holder is moved in the longitudinal direction of the rotary lid. If it bends, the lid opening member provided on the frame will become attached to the cassette body, which may impede the loading of the cassette, or the cassette lid will not open because it does not come into contact with the suppressor. Occurs/occurs.

To do this, a new member was added to the cassette holder body to open the lid, and the cassette lid was opened using a member, and the lid was opened using a fixed member attached to the frame of the cassette loading device. A configuration that allows the robot to move is being considered.

FIG. 4 is a side view showing the configuration of a conventional cassette loading device of this type, FIG. 5 is a cross-sectional view showing the configuration of the main part of FIG. 4, and FIGS. FIG. 2 is a diagram for explaining a tape cassette to which the present invention is directed.

In FIGS. 3(a) and (b), l is a cassette, 2 is a cassette body, and 3 is a rotating plate 3b which is rotated to the front of the cassette body 2 by a shaft 7, which is the rotation center of the rotating plate 3b that wraps around the side. The rotatable lid for the removably attached tape draw-out opening is normally locked by the locking pawl shown in the open state shown.

Reference numeral 5 denotes a lock release operation member connected to this lock pawl, and an insertion regulating groove 2a is formed on the left side of the cassette main body 2 along the insertion direction A of the cassette l from both sides of its front end to a position slightly past the rotary lid 3. The six-swivel lid 3, which is disposed in the same direction as shown in FIG. 4a and 4b indicate tape reels, and 6 indicates a gap between the cassette body 2 and the lid 3.

On the other hand, in the fourth (2I), 8 is the cassette holder main body,
9a and 9b are levers rotatably fixed to the cassette holder main body 8 and the frame lO attached to the VTR device main body shimmer, respectively. When the cassette holder main body 8 is pushed down, the levers 9a and 9b move counterclockwise. rotate in the direction. 11 is a protrusion provided integrally with the cassette holder 8 on the bottom surface of the cassette holder main body 8; 12 is an arrow 1;
This is a cassette suppressing member energized in three directions.

The protrusion 11 is configured to prevent unauthorized insertion, which may occur if the cassette l is inserted in the wrong state at the cassette insertion position, since the tip of the cassette 1 engages this protrusion 11 by 3W.

On the other hand, during this insertion, the upper surface of the cassette l is pressed downward by the suppressing member 12. The pressing member 12 is urged in the direction of the arrow 13 by the spring 15 around the shaft 14, and presses the upper surface of the cassette 1 downward.

Reference numeral 17 is a member for opening the lid, which is rotatable around a shaft 18, and when the cassette holder is down, it is rotated by a pin 19 provided on the frame 10 to open the lid of the cassette body 2. That is, as shown in Fig. 7FS5, the member 17 is provided outside the cassette holder main body 8, and the arAl
v l 7 b goes around the inside of the cassette holder 8 through the opening and is arranged so as to come into contact with the lower end of the rotary plate 3 b of the lid 3 .

[Problems to be Solved by the Invention] However, in the conventional cassette device installation as shown in FIGS. Due to variations in the dimensional tolerances of the parts, the tip of the member 17 when opening the lid has a very large wobble, and due to changes over time, the member 17 may fall inside the cassette holder body, and the lid opening part 17b is not connected to the cassette body 2. It interferes with.

In view of the above-mentioned points, the purpose of this MrJl cassette mounting device is to provide a cassette mounting device in which the lid opening provided on the side surface of the cassette holder body allows safe and reliable movement of the members.

[Means for Solving the Problems] In order to achieve the above object, the cassette mounting device of the present invention has a lid opening member on the side of the cassette holder that opens the rotating lid of the cassette as the cassette holder moves up and down. The lid opening member is provided with a protrusion on either the cassette holder side or the lid opening member to prevent the member from falling into the cassette holder.

[Function] With the configuration as described above, the cassette/lid opening member does not interfere with the cassette body, and the cassette lid can be opened and closed stably.

[Example] Fig. 1 is a side view showing the configuration of the cassette mounting device of the present invention, Fig. 2 is a sectional view of the main part of Fig. 1, and 17a is a projection provided on the member 17 for opening the lid. The same reference numerals as in FIGS. 3 to 5 indicate the same or phase 5 parts.

As shown in FIG. 2, the protrusion 17a is provided on the cassette holder main body 8 side of the lid opening member 17.

When the protrusion 17a comes into contact with the cassette holder main body 8, the end of the lid opening 17b has a ladder shape that does not cross the rotating plate 3a of the cassette rotating lid 3 and interfere with the cassette main body 2. (In addition, by making the shape of the lid opening part 17b as shown in FIG. 2 and increasing the contact area with the pin 19 provided on the frame IO, the cassette lid opening due to changes over time will be prevented from inside the cassette holder of the member 17. It is possible to reduce the amount of falling.

In the above-mentioned cassette loading device, the lid is opened by the member 17.
Is the cassette holder main body 8 falling inward or is the protrusion 17a
This prevents interference with the cassette lid opening 2. In addition, in this case, the protrusion 17a provided as a protrusion for the fA anti-glare IL is provided on the member side to open the lid, or
It is also possible to provide it on the cassette holder main body side, and it is better to choose one that is easy to process and inexpensive.

[Effects of the Invention] As explained below, this invention has a protrusion on the side surface of the cassette holder that prevents the member from falling inward to the inside of the cassette holder. The cassette lid can be opened and closed stably by providing the cassette holder side or the RI opening on either one of the members, and simply processing the member or the holder body to open the lid.
