Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tape recorder cassette loading device, and more particularly to a cassette loading device that can be commonly used for analog compact cassettes and digital compact cassettes.

[0002]

[Prior Art]

 Recently, a digital audio cassette tape recorder (hereinafter abbreviated as DAT) has been put into practical use and is becoming widespread as a new audio device that is opposed to analog audio cassette tape recorders.

[0003]

[Problems to be solved by the device]

 With the practical use of the DAT, it has been strongly desired to develop a compact cassette that can be commonly used by the DAT and the analog audio cassette tape recorder. Therefore, a digital compact cassette (DCC) compatible with a conventional analog compact cassette (ACC) tape recorder has been developed, but this has a big difference in the structure of the ACC. That is, in the case of DCC, a dust cover is provided to completely cover the hub hole, the tape opening window, etc. and prevent dust and dust from entering. Therefore, in a tape recorder that can be used for both ACC and DCC, it is necessary to slide the slide type dustproof cover to open it when the DCC is loaded.

[0004]

[The purpose of the device]

 The present invention provides a cassette loading device for a DCC-ACC dual-use tape recorder equipped with an operation mechanism that discriminates between DCC and ACC, and when the cassette is DCC, slides the dustproof cover to open it. To aim.

[0005]

The main feature of the present invention is that it comprises a pin for engagement that contacts the DC C sent to the cassette to the slide start end side of the dustproof cover of the cassette and contacts the front of the cassette to the ACC. There is. A second invention of the present application comprises a cassette support frame forming a cassette transfer path, and an operation mechanism provided on the cassette transfer path end side of the frame, wherein the operation mechanism is a frame. A swinging member having a swinging fulcrum at a predetermined swinging angle position by a spring bias, and a DCC provided on the free end side of the swinging member and sent to the transfer path. For the ACC, it contacts the slide start side of the dust-proof cover of the cassette, and for ACC, it has an engaging pin member that contacts the front surface of the cassette, and a rotating fulcrum on the frame, A lever member that engages with the rear surface of the cassette placed at the end position of the cassette transfer path and holds it by urging, and the swing member, and the lever member is provided at the rotation angle position of the swing member. A strike that engages the recess provided to prevent the swinging member from turning back. In that it consists of a per pin member has a gist.

[0006]

[Action]

 According to the above configuration, when the DCC or ACC sent to the cassette transfer path is the DCC, the operation mechanism that operates in association with the movement of the cassette is provided in the cassette. The sliding dustproof cover is opened.

[0007]

【Example】

 The drawings show an embodiment of the present invention. 1 to 5, reference numeral A is a cassette support frame that forms a cassette transfer path. Reference numerals 1 and 1 are opposite side plates that form a frame, and reference numerals 2 and 3 are top plates that connect both side plates at the front and rear positions. A receiving plate 1a for supporting the cassette is integrally formed at the lower ends of the side plates 1 and 1. A leaf spring 4 is fixed to the upper portions of the side plates 1 and 1 to elastically press the cassette supported by the receiving plate 1a from the upper surface.

One end of the swinging member 5 is rotatably provided at a predetermined portion inside the top plate 2 with the screw shaft 6 as a fulcrum. A cassette-engaging pin member 7 projecting downward is fixed to the free end side of the swinging member 5, and a stopper pin member 8 used for a purpose described later is fixed to a predetermined portion on the upper surface side of the swing plate 5. It projects upward from an arc-shaped guide slit 9 formed in 2. Reference numeral 10 denotes a biasing coil spring for holding the swinging member 5 at a predetermined rotation angle position, one end of which is provided on the top plate side, and the other end thereof is passed through an arc-shaped guide slit 11 formed on the top plate 2 to provide the swinging member. 5 are locked respectively.

At a predetermined portion on the front side of the top plate 2, an intermediate portion of the V-shaped lever member 12 is rotatably provided with a screw shaft 13 as a fulcrum. Reference numeral 14 denotes an urging coil spring for holding the lever member at a predetermined rotation angle position. This urging causes the lever member 12 to move to a rotation angle position where the lever portion 12a protruding to one of the fulcrums abuts the side plate. In addition to being held, the protrusion 12b formed at the tip of the lever portion 12a protrudes into the cassette transfer path. The lever portion 12c protruding to the other of the fulcrums is formed with two recesses 12d and 12e used for the purpose described later. Reference numeral 12f is a guide projection, which is inserted into the guide hole 2a of the top plate 2.

6 to 7 show the loading state of the DCC. The structure of DCC is shown in FIGS. Reference numeral 15 is a DCC cassette, and 16 is a dustproof cover. The dust-proof cover 16 is normally held in a closed position by a built-in spring. Further, the cassette 15 is provided with a recess 17, a taper portion 18, and a recess 19 required for opening the dust cover, from the outside to the inside of the dust cover.

As shown in FIG. 6, the cassette 15 is inserted by pushing the protruding portion 12b of the lever member 12 protruding into the cassette transfer path. When the pin member 7 of the rocking member 5 enters the recess 17 on the cassette side during the transfer of the cassette, the rocking member 5 starts to rotate around the shaft 6 as a fulcrum, so that the pin member 7 prevents the dust cover. 16 is pushed in the opening direction, and further, the dustproof cover 16 is pushed to the open position by the pin member 7 which is displaced along the taper portion 18, at which position the pin member 7 enters the concave portion 19, and the opening operation is completed. At the same time, the cassette 15 is stopped by a stopper piece 1b provided on the side plates 1,1. Since the stopper pin member 8 enters the concave portion 12d of the lever member 12 due to the rotation of the swinging member 5 between them, the swinging member 5 is held at the rotated angular position, and therefore the dust cover 16 also. Holds in open position. The state is shown in FIG.

As described above, the reproducing operation is performed after the loading operation accompanied by the opening operation of the dustproof cover of the cassette is completed, but the description of the operation is omitted.

When the loading of the cassette is completed, the front end protruding portion 12 b of the lever member 12 is placed on the rear surface of the cassette 15. Therefore, when the cassette is pushed back in the direction opposite to the loading, the protrusion 12b is pushed away, the lever member 12 is slightly rotated, and the pin member 8 is released from the recess 12d. Rotates back together with the pin member 7.

12 to 13 show ACC loading states. Reference numeral 20 is an ACC cassette. In the case of ACC, during transfer of the cassette 20, the pin member 7 of the swinging member 5 abuts on the front surface of the cassette and is displaced along the front surface of the cassette as it is. Is stopped by. During this time, the swing member 5 rotates, the stopper pin member 8 enters the recess 12e of the lever member 12, and the swing member 5 is held at that position. The state is shown in FIG.

It should be noted that when the DCC is loaded, the pin member 8 enters the recess 12d of the lever member 12 and the swinging member 5 can be held in the rotating position. Therefore, the recess 19 on the DCC side for receiving the pin member 7 is omitted. May be

[0016]
