Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a drive device in an optical memory device that records and/or reproduces information using a light beam.

[Conventional technology]

A drive device for an optical memory device using an optical disk or magneto-optical disk generally includes a spindle motor that rotates the disk, a pickup that records/reproduces information on the disk, a motor that drives the pickup in the disk radial direction, and a disk. A front panel with a cassette insertion slot is provided on the front of the deck unit, which has an autoloading/ejection mechanism for inserting and removing the cassette containing the cassette. I'm trying to escape.

In addition, in this type of drive device, in order to take out a cassette that remains attached to the deck unit due to a power outage or failure of the eject mechanism, for example, there is a method disclosed in Japanese Utility Model Application No. 63-40857. like,
A manual eject mechanism such as a manual rotation operation means for manually rotating the eject motor is provided.

[Problem to be solved by the invention]

However, in conventional drive devices, the front panel is fixed to the frame that holds the deck unit with screws or double-sided tape. For this reason, when the operating section of the manual eject mechanism is located inside the front panel, if you need to emergency eject a cassette from the deck unit in the event of a power outage or malfunction of the eject mechanism, it is troublesome and time-consuming to remove the front panel. Therefore, there is a problem that it takes a long time to quickly discharge the yl, and there is also a problem that the front panel is easily damaged when it is removed.

One way to solve this problem is to form an opening in the front panel so that the operating section inside the front panel can be operated from the outside through the front panel. A problem arises in that it is undesirable in terms of external design.

The present invention has been made in view of these conventional problems, and it is an object of the present invention to provide an optical memory drive device that is suitably configured so that the front panel can be attached to and detached from a container with a simple configuration.

[Means and effects for solving the problem] In order to achieve the above object, the present invention provides a front panel having an insertion opening for inserting a recording medium or a device main body to which this front panel is attached, which is elastically displaceable. a lock release operation part having a protrusion that is removably provided; and a locking part that is provided on the main body of the device or the front panel so as to be able to engage with the protrusion of the lock release operation part, the protrusion and the lock are engaged by the elastic force of the lock release operation part to lock the front panel to the device main body, and the lock release operation part is displaced against the elastic force to release the protrusion and the locking part. By releasing the engagement, the front panel is unlocked and can be removed from the device main body.
