Problems solved by technology

[0010] Like this, there is such a problem in the conventionally provided transport rollers: that is, since the surface of the rollers of the transport trays is smooth, if the rollers with smooth surfaces are used, debris, dust, etc. will be attached to the rollers, so that the rollers cannot be moved smoothly. shipping tray

Embodiment 1

[0037] Embodiments of the transport roller of the present invention will be described below with reference to the accompanying drawings. Fig. 1 is the front view of the conveying roller of the present embodiment, and Fig. 2 is an enlarged view showing the end face of line A-A in Fig. 1, and 1 in Fig. 2 is the conveying roller of the present embodiment.

[0038] The transport roller 1 of the present embodiment is composed of a shaft and a roller portion provided around the shaft other than both ends. That is, 2 in the figure is a shaft. In the present embodiment, the shaft 2 is formed by rigid bodies such as metal and hard resin. During use, the shaft 2 is connected to the drive unit and can rotate freely in the disk playback device.

[0039] Roller parts 3 are arranged around the outer periphery of the shaft 2. The roller parts 3 leave both ends to contact the disc and transport the disc to the turntable, or transport the disc on the turntable to the disc insertion port.

Abstract

Provided is a roller wheel for a disc delivery, which effectively prevents the disc delivery from degrading caused by the dust adhesion. The roller wheel for disc delivery (1) has a conical shape with a decreased radius along the length direction, and is provided with a plurality of linear or helical grooves (4) in the radial direction. The adhesive dust on the roller wheel is moved together with the roller wheel, and is scraped to the grooves by the surface of the wheel and the edge of the groove. Therefore, the degradation of delivery caused by the dust is prevented, and the delivery problem about the disc is effectively solved even the disc delivery device is long-term used or used under a dusty environment.

Description

technical field [0001] The present invention relates to a disc conveying roller used in a disc playback device loaded in a vehicle-mounted CD, a vehicle-mounted DVD, a vehicle-mounted navigator, a desktop personal computer, etc. Disc transport rollers that reduce disc transport performance due to the influence of dirt, dust, etc. Background technique [0002] Generally, disk playback devices have a disk transport mechanism for transporting a disc from a disc insertion port to a turntable, and such a disc transport mechanism provides a method for transporting a disc using transport rollers. [0003] Here, FIG. 10 is a perspective view of a disk playback device 31, and a disk playback substrate (not shown) is installed inside the disk playback device 31. As shown in FIG. In addition, the disc playback device 31 has a disc insertion port 32, and a disc such as an optical disc is inserted through the disc insertion port 32, and the disc is transported to a turntable inside the ...
