Description
SUMMARY OF THE INVENTION The magnetic recording/reproduction apparatus of this invention records/reproduces information on/from a magnetic tape by drawing out the magnetic tape from a tape cassette and allowing the magnetic tape to pass around a rotary head cylinder, having a rotary head, for a predetermined arc. The apparatus includes: a first chassis into which the tape cassette is inserted; and a second chassis having the rotary head cylinder mounted thereon and guiding movements of the first chassis toward and away from the rotary head cylinder, wherein the first chassis includes a chassis driving plate mounted thereon for adjusting a position of the first chassis relative to the second chassis, the second chassis includes a chassis driving arm mounted thereon for driving the first chassis, the chassis driving plate has a cam surface having a portion which is not perpendicular to a direction of the movement of the first chassis, the chassis driving arm has a protrusion which engages with the cam surface, and the chassis driving plate is disposed so as to be positionally adjusted by being moved in a direction substantially perpendicular to the direction of the movement of the first chassis.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan view of an embodiment of the magnetic recording/reproduction apparatus according to the present invention, illustrating a state in which a cassette can be placed/removed (UNLOADED mode);
FIG. 11 is a cross-sectional view of a MIC-SW of one embodiment of the magnetic recording/reproduction apparatus, taken along line A�A of FIG. 1;
FIG. 11 is a cross-sectional view of the MIC-SW 11, taken along line A�A of FIG. 1. Referring to FIGS. 1 and 11, the MIC-SW 11 is secured to the sub-chassis 3 with a screw (not shown). A sub-chassis reinforcing plate 103 is secured to the sub-chassis 3 with a screw (not shown). A U-shaped end portion 104 of the sub-chassis reinforcing plate 103 engages with an end 105 of the MIC-SW 11 so as to reinforce the MIC-SW 11. The MIC-SW 11 is provided with a contact 106 which comes into contact with a memory 107 located in the cassette 1 for effecting output/input of signals. When the contact 106 is pressed by the cassette 1, the MIC-SW 11 receives a reactive force. Since the body of the MIC-SW 11 is normally made of plastic, it is vulnerable to creep deformation. According to the present invention, however, the MIC-SW 11 can be reinforced by the sub-chassis reinforcing plate 103, allowing the body of the MIC-SW 11 to be thinned and thereby the entire apparatus to be made small.
