Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an eject device used in a magnetic recording tape running device.

In some conventional ejecting devices, a tape cassette holding means for removably holding a tape cassette is attached to a nokuntagraph mechanism. Then, the tape cassette holding means holding the tape cassette is moved in parallel by the pantograph mechanism between the first position and the second position in a direction along the rotation center line of the reel shaft of the magnetic recording tape running device. A tape cassette held by the tape cassette holding means when the tape cassette holding means is arranged in the first position.

The reel hub of the tape cassette is engaged with the reel shaft, and the reel hub of the tape cassette held by the tape cassette holding means is engaged with the reel shaft when the tape cassette holding means is disposed in the second position. .

Furthermore, in some conventional eject devices, one end of the tape cassette holding means is attached to the chassis of the magnetic recording tape transport device so as to be swingable between a first position and a second position. . The tape cassette holding means is the first
When the tape cassette holding means KJIIE! is positioned, the reel hub of the tape cassette held by the tape cassette holding means is engaged with the reel shaft of the magnetic recording tape traveling device, and the tape cassette holding means KJIIE! The decorative plate attached with D is disposed in the same plane as the outer surface of the nozzle of the magnetic recording tape running device. Further, the tape cassette holding means is the second tape cassette holding means.
When the reel hub and reel shaft of the tape cassette held by the tape cassette holding means are engaged with each other, the decorative plate of the tape cassette holding means is placed outside the housing of the magnetic recording tape traveling device. tilted relative to the surface.

In the conventional eject device having the above-mentioned configuration, the decorative plate attached to the tape cassette holding means and forming a part of the surface of the magnetic recording tape running device is designed to hold at least the tape held by the tape cassette holding means. It must have approximately the same orthographic area as the plane of the cassette housing, ie, the two surfaces that rotatably hold the reel hub.

Now, in recent years, in the industry of magnetic recording tape running devices in Japan, there has been a growing trend to make magnetic recording tape running devices thinner, reflecting the housing situation in Japan. This tendency is particularly noticeable in component type stereo cassette decks. In the case of component-type cassettes, tops, and keys, the cassette decks are stacked vertically together with other components such as amplifiers, chips, cabinets, and record players to save space.

Therefore, in the tape cassette, tode, and ki used in this way, in order to make it easy to visually confirm the increase or decrease in the diameter of the magnetic recording tape wound on the reel knob of the tape cassette, ) When the holding means is placed in the first position, the decorative plate of the tape cassette holding means is placed in the same plane as the vertical plane, i.e., the front surface, of the nousing of the cassette deck, and the tape held by the tape cassette holding means is The plane of the cassette housing is arranged parallel to the front surface of the cassette deck housing.

Therefore, the thickness of the skein, tode, and key is approximately the same as the length of the tape in the vertical direction, that is, the length of the decorative board in the vertical direction.
When reaching t, the space for arranging various operation switches and keys for operating the magnetic recording tape running device is reduced at the front of the housing of the cassette deck. In order to cope with this phenomenon, the dimensions of the various operating switches have been reduced, and the various operating switches are arranged on the decorative plate of the tray holding means.

However, the reduction in size of the operating switch causes problems such as erroneous operation of the operating switch and difficulty in handling when using the operating switch. The arrangement of the operating switch on the decorative board allows the operating switch to be electrically connected to the magnetic recording tape running device since the decorative board is movable between the first position and the second position. The electrical connection means 2, such as an electrical cord, is likely to be disconnected, creating a problem of reduced reliability of the magnetic recording tape running device.

This invention has been made based on the above circumstances, and an object of the present invention is to not only reduce the thickness of a magnetic recording tape running device, but also to improve the operability of various operation switches of the magnetic recording tape running device. Reliability can also be improved, and more importantly, the ejector malfunction due to the movement of the second substrate to the second position while the magnetic recording tape transport device is set to the magnetic placement tape transport mode can be improved. An object of the present invention is to provide an eject device for a magnetic recording tape running device that has a simple configuration that can prevent the above problems.

The length in the longitudinal direction of the cassette 20 is smaller than the length from the surface where the magnetic head/pinch roller insertion window is formed to the surface opposite this surface. Therefore, by making the magnetic recording tape running device thinner, the space for arranging various operation switches on the front surface of the housing of the magnetic recording tape running device is reduced by the vertical length of the housing of the tape cassette 20, that is, approximately the height. Even if they are the same, they can be sufficiently secured. Therefore, as shown in FIG. 1, although the magnetic recording chip traveling device has been made thinner, the various operation buttons 12 are not arranged on the decorative plate 26.

Therefore, with such a configuration, the length of the decorative board in the vertical direction and the length of the tape cassette in the vertical direction can be reduced. The space for arranging the operation switches of the magnetic recording tape running device is becoming thinner, which increases the length of the housing in the vertical direction, that is, the height.

Even if it reaches approximately the same level as the above, it can be sufficiently secured. Therefore, even though the magnetic recording tape running device has been made thinner, the size of the operation switch can be increased without disposing the operation switch on the decorative board. This means that the operability and reliability of the various operation switches of the magnetic recording tape running device are improved.

In addition, the guide pin of the third board is engaged by both the ejector, the auxiliary eject switch, and the ejector.
Since the sub-eject switch is held in the first position by the sub-eject switch while the magnetic recording tape running mode is set, the eject switch is held in the first position while the magnetic recording tape running mode is set. Even if the holding of the guide pin is released, the reel collar of the tape cassette and the reel shaft can be maintained in alignment by moving the second board to the second position, so malfunction of the ejecting device can be prevented. can.
