Abstract

PURPOSE:To load erectly a tape cassette by forming link mechanisms for supporting and driving a cassette holder and two guide groove parts for regulating the operating locus of the cassette on both the sides of the cassette holder. CONSTITUTION:When the tape cassette 1 is loaded, the cassette holder 2 and a guide plate 10 are moved along the long hole 6a of a holder garage 6 and the long hole 10a of a guide plate 10 in the approximate loading direction of the tape cassette 1, interlocking with the rotation of a driving gear 7. When the driving gear 7 continues to rotate, the guide plate 10 is rotated around the rotation supporting point 5a of the slide plate 5 along a guide groove 10b in the clockwise direction. After the projected shaft part 10c of the guide plate 10 has been moved up to the terminal of the arc part of the guide plate 10 has been moved up to the terminal of the arc part of the guide groove 12a, the projected shaft part 10c is guided by the straight part of the guide groove 12a of the guide member 12 and the guide plate 10 is straight moved in the approximately parallel direction to the axial direction of the reel board 11, so that tape reel in the tape cassette 1 is loaded to the reel board 11.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cassette loading device that can be used in video tape recorders and the like.

2. Description of the Related Art Conventionally, a tape cassette for a VH8 video tape recorder (hereinafter referred to as VTR) has an opening for drawing out the tape and a guard panel for shielding the opening. When a tape cassette configured to be inserted into a VTR is used and the VTR is constructed in such a way that the tape cassette is placed upright with the tape cassette installed, the tape cassette is placed in an upright position, as shown in Fig. 6. Most of them were equipped with a cassette loading device. In FIG. 6, 61 is the VTR body, 62 is a cassette holder, and the cassette 53, which can be seen through the transparent part in the ejected state, is used for taking out the cassette. 64 is a push button for operation, and 65 is a button that is rotatable around the support shaft 55a.
It is a bundle.

Problems to be Solved by the Invention In the above conventional configuration, when an ordinary tape cassette is used, two characters and two figures are written on the cassette.

Not only are all the labels etc. upside down making it hard to see, but
There was a problem in that the quality of the product was significantly lowered.

In the present invention, the tape cassette is installed upside down, and the characters, labels, etc. on the cassette are upside down.
The purpose is to eliminate the difficulty of viewing titles, etc., and prevent a decline in quality.

Means for Solving the Problems In order to solve the above-mentioned problems, the cassette mounting device of the present invention includes a link mechanism for supporting and driving the cassette holder on both sides of the cassette holder for storing the tape cassette, and a link mechanism for supporting and driving the cassette holder. It is constructed with two guide grooves that regulate the trajectory.

Effects of the present invention With the above-described configuration, when inserting a tape cassette into a cassette holder, it can be inserted from the front with the opening of the tape drawer reservoir of the cassette being slightly lower than horizontal, and after the cassette holder is moved, the tape cassette can be inserted from the front. When the tape cassette is in the upper position, that is, when the tape cassette is erected, the cassette can be seen through from the front.

Example The configuration of an embodiment of the present invention will be explained with reference to FIG.

A cassette holder 2 for storing a tape cassette 1 is rotatably held on a pivot point 611 of a slide plate 6 which is slidably held on a side plate 4 fixed to a substrate 3 along guide grooves 4a and 4b. It is held in the holder garage 6 so as to be slidable along a long hole 6& formed in the holder garage 6 and substantially parallel to the tape cassette insertion direction. Also, the long hole saK of the holder garage e? The protruding shaft portion 2 & of the cassette holder 2 that slides is rotatably held by the side plate 4 and rotatably attached to the tip of a lever 8 fixed to a drive gear 7 engaged with a drive source (not shown). A straight line that rotatably engages with one end of the link lever 9 held by the lever 9 and that also engages with the elongated hole 101L that engages with the rotation fulcrum 6a and the protruding shaft portion 6a provided on the slide plate 5. The guide plate 10 is rotatably engaged with one end of a guide plate 10 having a guide groove 10b formed by an arcuate portion and a circular arc portion. Further, the side plate 4 is formed by a linear part attached to the base plate 3 and substantially parallel to the axial direction of the reel stand 11, and a circular arc part centered on the rotation fulcrum 5IL of the slide plate 5, and the guide plate 1o
A guide groove 12 that guides the protrusion shaft portion 10c1 provided in the
A guide member 12 having an IL is fixed.

Next, the operation will be explained with reference to FIGS. 1 to 5. First, when the tape cassette 1 is inserted into the state shown in FIG. Start rotating clockwise. As the drive gear 7 rotates, the cassette holder 2 into which the tape cassette 1 has been inserted and the guide plate 1o move into the long hole 81 of the holder garage 6.
The tape cassette 1 is moved approximately in the insertion direction 7 of the tape cassette 1 along the elongated hole 1oaK of the guide plate 10 (tape cassette retracting operation), resulting in the state shown in FIG. When the drive gear 7 continues to rotate further, the guide plate 10 rotates clockwise along the guide groove 1ob using the rotation fulcrum 6a of the slide plate 50 as a fulcrum, as shown in FIG. At this time, the holder garage 6, cassette holder 2, and tape cassette 1 operate in the same manner as the guide plate 10. It goes without saying that the subsequent operations of the cassette holder 2, holder garage 6, and tape cassette 1 are the same as those of the guide plate 10.

The guide plate 10 is rotated to the state shown in FIG. 4 (the state in which the protrusion shaft portion 10C of the guide plate 1o has moved to the end of the circular arc portion of the guide groove 122L of the guide member 12), and then the protrusion shaft of the guide plate 10 is rotated. Part 10C+ is guide member 1
Guide plate 1 is guided by the straight part of guide groove 12a of No.
0 performs a linear motion in a direction substantially parallel to the axial direction of the reel stand 11, and stops in the state shown in FIG. 1 installation is completed.

As explained above, according to the configuration of this embodiment, the tape cassette inserted from the front makes a linear movement in the insertion direction, then performs a rotation operation, and then makes a linear movement again, so that the tape cassette is erected. The tape cassette can be loaded in this state.

Effects of the Invention As described above, according to the present invention, when inserting a tape cassette into a cassette holder, it can be inserted from the opening side for drawing out the tape, and when the tape cassette is attached to the reel stand, the tape cassette can be inserted from the opening side for drawing out the tape. Since the opening is located upward, an excellent effect can be obtained in that the tape cassette can be seen through from the front with the cassette erected.
