Abstract

PURPOSE:To contrive to improve operational properties so that a small-sized tape cassette can be used in the same way as a standard type tape cassette. CONSTITUTION:When a standard tape cassette 200 is inserted from a cassette insertion opening 111, the cassette comes into contact with the standard cassette first abutment part and second abutment part 123 of a blinder 120. The blinder 120 rotates by this contact. Thereafter, when the cassette 200 is moved in the X-direction, the cassette is guided by the standard cassette left guide part, right guide part and lower guide part 143 of a holder 140 and mounted in the holder 140. Then, when a small-sized type cassette 210 is inserted into the insertion opening 111, the cassette 210 abuts on a small-sized cassette abutment part and the blinder 120 starts rotation. After that, when the cassette 210 is moved in the X-direction, the blinder 120 rotates counterclockwise while starting the insertion of the cassette into the holder 140. In this case, the cassette 210 is guided by a small-sized cassette lower guided part 144, left guide part and right guide part and mounted in the holder 140.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cassette mounting device for a magnetic recording/reproducing apparatus which can be applied to either a standard tape cassette or a small-sized tape cassette.

0002

[Prior Art] In recent years, video tape recorders (hereinafter referred to as V
Cassettes used in magnetic recording and reproducing devices such as TR (abbreviated as TR) include not only standard tape cassettes but also small tape cassettes that are smaller than standard tape cassettes and are widely used in the camera-integrated VTR market. Conventionally, in order to record and play back this small tape cassette with a magnetic recording/playback device for standard tape cassettes, it was necessary to use a special adapter to obtain a tape loop equivalent to that of a standard tape cassette. However, a small tape cassette had to be attached to and detached from the adapter, resulting in poor operability.

[0003] Therefore, the present applicant has proposed a magnetic recording and reproducing apparatus that does not require the use of an adapter, as shown in Japanese Patent Application No. 119423/1993, which was previously filed. With this device, both standard tape cassettes and small tape cassettes can be selectively loaded into the device main body using one cassette holding means without using a dedicated adapter, which improves operability. This will lead to improvement.

0004

[Problems to be Solved by the Invention] However, the above configuration has the following problems.

(1) Since a reversing means corresponding to the standard type tape cassette and a small tape cassette, and a drive mechanism for the reversing means for operating the reversing means are required, compared to a magnetic recording/reproducing device exclusively for standard type tape cassettes, , the number of parts increases, which leads to an increase in costs.

(2) If only a cover means compatible with standard tape cassettes is provided, such as in a magnetic recording/reproducing device exclusively for standard tape cassettes, the user may insert a small tape cassette into the cassette insertion slot. When doing so, it is unclear from which position in the cassette insertion slot the cassette should be inserted, and furthermore, if that position is not a normal position, it is difficult to insert the cassette into the cassette holder.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention provides a magnetic recording and reproducing apparatus with improved operability, which allows use of small tape cassettes as well as standard tape cassettes.

[0008]

Means for Solving the Problems In order to solve the above problems, a magnetic recording and reproducing apparatus according to the invention as set forth in claim 1 has a cassette insertion slot into which a standard tape cassette or a small tape cassette smaller than the standard tape cassette is inserted. a holding means for holding a standard tape cassette or a small tape cassette inserted from the cassette insertion slot; an operating position that substantially covers the part of the holding means into which the standard tape cassette is inserted; The cover means is movable to a non-operating position that does not interfere with the operation of inserting the tape into the holding means, and has a guide portion that guides the small tape cassette inserted from the cassette insertion slot to a predetermined position in the holding means. be.

[0009]

[Operation] By adopting the above-described structure, the present invention clarifies the target position of the small tape cassette to be inserted into the device, and the small tape cassette inserted from the cassette insertion opening is guided to the guide portion of the covering means. It becomes possible to insert and hold the holding means.

Therefore, the standard tape cassette 200 can be inserted into the cassette holder 140 while abutting the standard cassette first abutting part 122 and the standard cassette second abutting part 123, as shown in FIG. On the other hand, the small tape cassette 21
0 is the standard cassette first contact portion 12 as shown in FIG.
2 right end portion 122a and standard cassette second contact portion 123
It is restricted in the directions of arrows x and x' in FIG. 2 by the left end 123a of the blinder 120, and can be inserted into the cassette holder 140 by coming into contact with the lower edge 120a of the blinder 120.

The operation of the magnetic recording/reproducing apparatus constructed as described above will be explained below with reference to FIGS. 1 to 7.

First, the operation of mounting the standard tape cassette 200 onto the cassette holder 140 will be described.

In FIG. 3, a standard tape cassette 20
0 through the cassette insertion opening 111, the standard tape cassette comes into contact with the standard cassette first contact portion 122 and the standard cassette second contact portion 123 of the blinder 120. Due to this contact of the standard tape cassette 200, the blinder 120 receives a rotational moment in the counterclockwise direction in FIG. 3, and rotates to the position shown in FIG. 6 against the biasing force of the blinder spring 127. After this, standard tape cassette 200
When the is moved in the direction of the arrow x in FIG. 3, the standard cassette is guided by the standard cassette left guide part 141, standard cassette right guide part 142, and standard cassette bottom guide part 143 of the cassette holder 140, as shown in FIG. It will be installed.

Next, the operation of mounting the small tape cassette 210 onto the cassette holder 140 will be described.

The position where the small tape cassette 210 is inserted is made clear by the standard cassette first abutting portion 122 and the standard cassette second abutting portion 123 of the blinder 120. Therefore, in FIG. 2, the small tape cassette 210
When the small tape cassette 2 is inserted from a position substantially opposite to the small cassette abutting portion 121 of the cassette insertion slot 111, the small tape cassette 2
10 abuts against a small cassette abutting portion 121 of a blinder 120. Due to this contact of the small tape cassette, the blinder 120 receives a rotation moment in the counterclockwise direction in FIG. 3, and starts rotating against the biasing force of the blinder spring 127. After that, when the small tape cassette 210 is moved in the direction of arrow x in FIG. 3, the blinder 120 rotates counterclockwise in FIG. The left end of the cassette second contact portion 123 causes the arrows x and x' in FIG.
Insertion into the cassette holder 140 is started under direction restrictions. At this time, the small tape cassette 210 is inserted while being guided by the small cassette lower guide part 144, the small cassette left guide part 144, and the small cassette right guide part 145 of the cassette holder 140. Then, as shown in FIG. 7, the cassette holder 140 is mounted while the blinder 120 maintains the restriction in the directions of arrows x and x' in FIG.

As described above, according to this embodiment, the operating position substantially covers the portion of the holding means into which the standard tape cassette is inserted, and the operation of inserting the standard tape cassette or the small tape cassette into the holding means is not hindered. By providing a cover means that is movable to a non-operating position and has a guide portion that guides a small tape cassette inserted from the cassette insertion slot to a predetermined position of the holding means, the position where the small tape cassette is inserted into the device can be adjusted. In addition, the insertion of the small tape cassette can be regulated during the entire process from the start of inserting the small tape cassette into the device to the completion of mounting it on the holding means, which improves the operability of inserting the cassette. I can figure it out.

Note that in this embodiment, the blinder 1
Although the shape of No. 20 was described above, the shape is not limited to this. For example, as shown in FIG. 8, the portion that contacts the small tape cassette 210 may be tapered relative to the portion that contacts the standard tape cassette 200, or as shown in FIG. The direction of the taper may be reversed. In any of the blinders, like the blinder 120 shown in FIG.
and the left end portion 123a of the standard cassette second contact portion 123, the same effects as in this embodiment can be obtained. That is, the small tape cassette 210 is placed in the cassette holder 140.
The shape may be arbitrary as long as the blinder is provided with a portion corresponding to the right end 122a of the standard cassette first contact portion 122 and the left end 123a of the standard cassette second contact portion 123 for insertion into the blind.

[0021]

As described above, the present invention provides 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 standard tape cassette or small tape cassette inserted from the cassette insertion slot. and is movable between an operating position that substantially covers a portion of the holding means into which a standard tape cassette is inserted, and an inoperative position that does not interfere with the operation of inserting a standard tape cassette or a small tape cassette into the holding means. and a cover means having a guide portion that guides the small tape cassette inserted from the cassette insertion slot to a predetermined position of the holding means, thereby making it clear where to insert the small tape cassette into the device, and Since the insertion of the small tape cassette can be restricted during the entire process from the start of insertion of the small tape cassette into the apparatus until the completion of mounting on the holding means, the operability of inserting the cassette can be improved. Furthermore, it is possible to restrict the insertion of small tape cassettes without adding any parts compared to conventional methods, and a special tape cassette is installed to detect whether a standard tape cassette or a small tape cassette is being inserted. Since no detection means is required, an inexpensive device can be provided.
