摘要:
Provided is a disk carrying mechanism, in which a guide member (32) is installed on a disk guide block (41) and the disk guide block (41) with the guide member (32) being disposed on an opposite side of a roller (31) with a carrying route therebetween. The guide member (32) is formed as a ridge extending in a direction orthogonal to a direction of a carrying route and inclined from a center part to a peripheral edge part of a disk so that its height can be increased.

A disc transfer section for transferring an optical disc by guide members and a transfer roller is disposed adjacent to an opening of a casing 110. A detector 500 for detecting the optical disc is disposed adjacent to the opening. When unloading the optical disc, the peripheral edge of the optical disc contacts with slide members so that the slide members are slid, thereby sensor switches SW1 to SW4 are appropriately switched on and off. Based on a time difference between the timings of the on/off switchings, the relation between a movement trajectory of the center of the optical disc and an axis of symmetry that is a straight line indicating a transfer direction at the center of the opening is judged in order to control the drive of a transfer motor according to the movement trajectory. The amount of advancement when the unloading is completed is kept constant.

A record medium reproduction unit has a main casing, a transfer device, a pair of sensing pins, a sensing device, and a decision device. The transfer device transfers a larger disk record medium and a smaller disk record medium into and out of the main casing. The sensing pins are movable toward and away from each other and each contact an outer edge of the larger disk record medium when the larger disk record medium enters the main casing. The decision device determines which is inserted into the main casing, the larger disk record medium, the smaller disk record medium, or a special form record medium such as a card-shaped CD based on information supplied from the pair of sensing pins.

A stepping motor driving system includes: a stepping motor that rotates at a predetermined angle according to a driving pulse signal, a vibration detector that detects vibration to output a vibration signal, and a stepping motor control unit that controls the driving pulse signal, which is applied to the stepping motor, to rotate the stepping motor at the predetermined angle. The driving pulse signal includes a start-up current which is required for rotating the stepping motor at a unit angle and a holding current which maintains a rotational angle of the stepping motor rotated by the start-up current. The stepping motor control unit changes the level of the holding current according to the vibration signal which is outputted from the vibration detector.

摘要:
A main frame supports a receiving-side connector to which a connecting-side connector is connected in movable manner toward inside. A holding unit holds the receiving-side connector that is moved to the inside. A connector biasing unit applies a biasing force toward outside to the receiving-side connector. A hold releasing unit releases a hold by the holding unit, and moves the receiving-side connector to the outside by the biasing force. A pressing-force applying unit applies, when the receiving-side connector is not moved by the biasing force, a pressing force for ejecting the receiving-side connector to the receiving-side connector.
摘要:
A connecting-side connector is connected to a receiving-side connector. A main frame supports the receiving-side connector in such a manner that the receiving-side connector is movable in a connection direction. A control unit performs a control of a movement of the receiving-side connector in the connection direction and a release of the control each time a pressing force is applied to the connecting-side connector in the connection direction.
