The drive arm 122 is inserted into the groove 132 and rotates along the inner surface of the first outer casing side plate 61.

The video tape recorder 60 of the embodiment has the above-described configuration. Therefore, when the tape cartridge shown in FIG.
Is rotated clockwise by the spring force of the torsion coil spring 121 to make the connector 71 stand by at a position deviated from the movement locus of the tape cartridge 1.

When it is detected that the tape cartridge 1 has been inserted, the first and second slide plates 66 and 67 slide as shown in FIG. Lid member 16
Lower the end on the contact terminal side on the back side opposite to the above.

Further, the first and second slide plates 61 and 62
Slides, the lid member 16 side of the tape cartridge 1 descends, and the first slide plate 61
Of the slide plate engaging pin 126
And pushes down the pin 126 to move the drive arm 12
2 and the movable connector holder 72 are rotated, and the spring terminals 101... 101 of the connector 71 supported by the movable holder 72 are replaced with the contact terminals 53 of the auxiliary storage device 50.
... 53.

The spring terminal 101 makes sliding contact with the contact terminal 53 while rotating about the pivot shaft 111, and since the sliding distance of the spring terminal 101 with respect to the contact terminal 53 is large, the spring terminal 101 or the contact terminal If foreign matter has adhered to 53, the foreign matter is removed by sliding, and poor contact is prevented.

As shown in FIG.
When the length of each of the spring terminals 101 is changed,
In this order, p, 101q, 101r, 101s, and 101t come into contact with the contact terminal 53 and slide. For this reason,
The signal line terminal, the signal line ground terminal, the power line terminal, and the power line ground terminal are connected in this order, and the signal line terminal is connected before the power line terminal. Operation becomes stable.

Although the drive arm 122 of the connector holder drive mechanism 73 is pressed by the cam portion 129 provided on the slide plate 66, the drive arm 122 may be pressed by the cartridge holder 70.

[0064]

According to the recording / reproducing apparatus of the first aspect, the connector slides on and comes into contact with the contact terminal.
When foreign matter is attached to the contact terminal, the foreign matter can be removed to prevent poor contact beforehand. Therefore, it is possible to provide a highly reliable streamer or VTR for a tape cartridge equipped with a memory IC.

According to the recording / reproducing apparatus of the second aspect, since the length of protrusion of the spring terminal of the connector is changed,
The terminal of the signal line can be connected before the terminal of the power supply line, and the operation of the circuit is stabilized.
