DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a recording, reproducing, and recording/reproducing apparatus suitable for use in recording, reproducing, and recording/reproducing information on and from a tape-like recording medium housed in a tape cassette.
BACKGROUND ART
Heretofore, tape players for use as recording, reproducing, and recording/reproducing apparatus have a plurality of guide rollers which can be moved in certain directions to effect a tape loading operation by pulling a predetermined length of tape from a tape cassette and winding the tape around a rotary head cylinder and a tape unloading operation by rewinding and storing the drawn tape into the tape cassette. The guide rollers are moved by drive forces produced by a motor. Rotation of hub drive shafts for rewinding the tape in the tape unloading operation is also caused by drive forces of the motor.
Since the tape loading and unloading operations of the conventional tape players are carried out by the drive forces of the motor, the tape players have a large number of constituent parts, are complex in structure, difficult to be reduced in size, highly costly, and have a high power requirement.
DISCLOSURE OF THE INVENTION
It is therefore an object of the present invention to provide a tape player which can manually be actuated easily in tape loading and unloading operations without the need for the drive forces of a motor, has a smaller number of constituent parts, is simpler in structure, and may be reduced in size and cost.
According to the present invention, a recording, reproducing, and recording/reproducing apparatus for a tape-like recording medium housed in a tape cassette comprises, as shown in FIGS. 1 through 3, for example, a main chassis with a rotary head cylinder mounted thereon, and a subchassis coupled to the main chassis for sliding movement relative to the main chassis in directions toward and away from the rotary head cylinder, the subchassis having a pair of hub drive shafts and a plurality of guide rollers movable in a predetermined direction, the arrangement being such that the tape housed in the tape cassette loaded on the subchassis can be pulled out of the tape cassette and wound around the rotary head cylinder by moving the guide rollers in response to relative sliding movement of the main chassis and the subchassis.
The guide rollers are movable to a predetermined position on the main chassis by sliding movement of the subchassis.
A first slide member and a second slide member are disposed on the subchassis, the guide rollers being mounted on the second slide member, the first slide member and the second slide member being slidable upon sliding movement of the subchassis.
A means is mounted on the subchassis for increasing sliding movement of the second slide member with respect to sliding movement of the subchassis.
The first slide member has a tape holding member for preventing the tape in the loaded tape cassette from riding onto the rotary head cylinder.
The tape holding member has opening means for opening a lid of the tape cassette.
The recording, reproducing, and recording/reproducing apparatus further comprises a holder for holding the tape cassette, the holder being vertically movably mounted on the subchassis, the holder being slidable with the subchassis with respect to the main chassis when the holder is in a lowered position.
The recording, reproducing, and recording/reproducing apparatus further comprises a frame with a lid member attached thereto, the frame being angularly movably mounted on the main chassis, and a link mechanism for vertically moving the holder in ganged relation to angular movement of the frame.
The link mechanism comprises a cam plate slidable by the frame, the cam plate having a first cam groove inclined for vertically moving the holder, the holder having a shaft engaging in the first cam groove, and a second cam groove contiguous to the first cam groove and extending parallel to a direction in which the subchassis and the main chassis slide with respect to each other
