    • A card (12) is inserted by pushing against a rubber roller (44) at the leading end of the card (12). The action of the rubber roller (44) pivots an actuation lever (24) to actuate a switch (36), which, in turn, starts a motor (16). The card (12) is moved inwardly by the rotation of the rubber roller (44) thereby pushing the card against support legs (62) causing a pinion (58) to engage with a rack (56) mounted on a card holder (48). The card holder (48) then holds the card (12) and is driven by the pinion (58) causing hook portions (84a, 84b) of pushing arms (72a, 72b) to engage the trailing edge (12b) of the card (12) thereby connecting the card (12) with contact pins (22) of an electrical connector (20) by pushing the card at its trailing edge.

    • A tape player having two belts wound around a motor shaft, with one further wound around flywheels provided with capstans and another further wound around a reel shaft drive system, said flywheels and said reel shaft drive system being adapted to be separately rotated by the different belts, respectively.BACKGROUND OF THE INVENTIONThis invention relates to a tape player art and more particularly to a tape player which can enjoy minimized wow and flutter as well as reduced thickness in construction.The reduction in thickness of a tape player will not only contribute to reduction of materials to be used for manufacturing of the tape player but also enable the tape player to be suitably installed with advantage in a limited space for a driver's seat in a car. In conventional mobile tape players, it is general that wow and flutter is caused principally by a load fluctuation in the tape drive system. The conventional mobile tape players generally employ such a system that flywheels are driven by a belt wound around a motor reel. The reel driver is driven through a flywheel drive of a constant rate and a drive system is formed through a fast-forward/rewind mechanism, so that the drive load applied thereby fluctuates considerably and wow and flutter is inevitably caused. On the other hand, to establish such a reel driver-drive system, there should be employed such a structure that a gear or wheel is mounted coaxially with the flywheel and the drive system should be formed through the gear or wheel coaxial with the flywheel. Consequently, the flywheel assembly becomes inevitably bulky and thick. Furthermore, the flywheel is provided with a capstan and a tape pack mounted thereon, requiring a further mechanism for loading/unloading the tape pack thereon which unavoidably limits the desired reduction in thickness of the tape player.
