Abstract: In the connector device for IC card according to the present invention, when an IC card as inserted into the connector device is to be ejected, a push rod is projected up to a projecting position and is pushed in this state, whereby the IC card is ejected through a single transfer pin. In the event the push rod should be projected by mistake despite the ejection of the IC card being not required, a knob is turned at the projecting position, causing the transfer pin to shift from a first heart cam groove to a second heart cam groove, and in this state the push rod is pushed toward a push-in position. Since by turning a single transfer pin the IC card ejecting motion is cancelled and the IC card is maintained in its inserted state, the usual ejecting motion requiring frequent operations becomes simple and easy in comparison with the prior art.

Abstract: In an IC card connector device capable of holding a push rod 4 at a push position while an IC card 1 is connected, a heart-shaped cam groove 10 capable of holding the push rod 4 at two positions or a push position and a projecting position in association with a first transmission pin 15 and a circulating type cam groove 11 and an escape groove 12 which are selectively traced by a second transmission pin 16 in accordance with a projecting amount of the push rod 4 are formed on the outside surface of a frame 3 having a guide groove 3a which is formed on the inside surface thereof and into and from which the IC card 1 is inserted and withdrawn and the receiving portion 13b of a drive plate 13 which associates with an eject arm 5 is permitted to enter into and exit from the circulating type cam groove 11.

Abstract: A magnetic recorder/reproducer includes a rotary drum supporting first and second playback heads and first and second recording heads for reading information from and writing information in a tape running obliquely to a plane in which the heads rotate, the first playback head, the first recording head, the second playback head, and the second recording head being arranged in the order named in a direction in which the heads rotate, the recording heads being positioned on the rotary drum at a height different from the height at which the playback heads are positioned on the rotary drum, the arrangement being such that while information recorded in a given track on the tape is being reproduced by the ith (i=1, 2) playback head, information is recorded on the same track by the ith recording head. The recording and playback heads are switched over each time the rotary drum makes a half rotation at switching timings that are .pi./2 out of phase.
