<p>PURPOSE:To contrive to improve operability and feeling for an operation at the time of pushing a cassette in a device, by turning a driving arm directly by a rack having a double sheet structure provided at one side of a side plate being arranged at both sides of a cassette holder through a guide capable of being displaced horizontally. CONSTITUTION:In a state where the loading of the cassette has been completed, a gear 42 whose phase is fitted for a gear 37 provided at a first rack 34, is engaged with a gear 36 unified in one body with the driving arm 31. At the time of ejecting the cassette, the operation in the reverse direction of a loading operation is performed, and in a vertical operation period, the gear 42 on a second rack 40 is engaged with the gear 36 of the driving arm 31 as in the case of the gear of the first rack 34. The first rack is slided within a slotted hole provided at the second rack, by the driving arm provided with the second rack being engaged with an output gear, and capable of being displaced horizontally, and the gear engaged with the gear provided at the first rack being linked mutually with the second rack by a tension spring. In this way, it is possible to improve the operability, and the feeling for the operation at the time of inserting the cassette by a user.</p> |
