AI Technical Summary

Benefits of technology

This design minimizes the number of components, reduces assembly and manufacturing costs, and enables smooth disk loading from any position without resistance, while maintaining effective ejection detection and handling.

Problems solved by technology

This arrangement needs many parts and accordingly results in an increase in the number of steps of assembly adjustment, leading to an increase in assembly cost.
In this case, if a disk is inserted from a position close to the second rotary arm, the disk will come into contact with the transport rollers but the first rotary arm will not be rotated sufficiently and accordingly will fail to switch on the switch SW2.
Unfortunately, the transport rollers will not start to rotate.
Disadvantageously, a coupling mechanism having a complicated structure is needed, thus allowing a disk drive to have a complicated configuration, which leads to an increase in manufacturing cost.

Embodiment Construction

[0035]As illustrated in FIG. 2, a disk drive 1 includes a housing 2 and a panel 3 secured to a front portion of the housing 2. The panel 3 has a slit-shaped opening 4. If the disk drive 1 is used in a vehicle, such as an automobile, the housing 2 is embedded in an instrument panel of the automobile and the panel 3 is flush with the instrument panel.

[0036]FIGS. 1 to 6 illustrate the disk drive 1 in an inverted orientation or upside down. When actually used, the disk drive 1 is oriented such that a Z1 direction indicates an upward direction and a Z2 direction indicates a downward direction. In FIGS. 1 to 8, a Y1 direction indicates a loading direction in which a disk is transported into the housing 2, and a Y2 direction indicates an unloading direction in which the disk is transported out of the housing 2. A transport center line O is a virtual line that passes through a central part of a transport roller 12 along its axis and a central part of the opening 4 along its width so as to e...

Abstract

A disk drive includes an insertion detection unit disposed at a position deviating from a transport center line in a first direction, a transport roller, and an opposing member that holds a disk together with the transport roller. The opposing member has a second guiding recess located in a second direction relative to the transport center line. The recess of the opposing member and the transport roller define a space therebetween to receive the disk inserted from a position deviating from the transport center line in the second direction.

Description

RELATED APPLICATION[0001]The present application claims priority to Japanese Patent Application Number 2014-040348, filed Mar. 3, 2014, the entirety of which is hereby incorporated by reference.BACKGROUND[0002]1. Field[0003]The present invention relates to a disk drive including a disk insertion detection unit.[0004]2. Description of the Related Art[0005]Slot-loading disk drives are typically used in vehicles. Japanese Unexamined Patent Application Publication No. 2008-135106 discloses a disk drive including two rotary arms arranged inside an opening through which a disk is inserted. The two rotary arms rotate independently of each other. One of the two rotary arms causes switching of a switch SW1 and switching of a switch SW2, and the other one of the two rotary arms causes switching of a switch SW3.[0006]When a disk is inserted through the opening, the rim of the disk presses the two rotary arms, thus rotating the rotary arms. When the two rotary arms rotate and at least one of th...
