Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording and / or reproducing apparatus.
That constitute the front part of the outer housing of electronic equipment such as
And a front panel and this front panel.
The present invention relates to a recording and / or reproducing apparatus having an outer casing. [0002] Conventionally, a so-called optical disc play or the like
Recording and / or reproduction of information signals using a recording medium
Recording and / or playback device configured to perform
Have been. Such recording and / or playback devices are
A surface portion has an outer housing configured by a front panel,
Recording of information signals on the recording medium in the outer casing
And / or a recording and / or reproducing unit for performing reproduction is provided.
It is configured. An optical disc is used as the recording medium.
Disks such as magnetic disks, magneto-optical disks, and magnetic disks
Or using a recording tape configured as a tape cassette
Can be On the front panel, the recording medium is provided.
When the recording medium is inserted into and out of the outer casing
An opening is formed to enable operation. This opening
Corresponds to the shape of the recording medium, for example,
It has a slit-like shape. And this
The opening of the recording medium is not only used when the recording medium is inserted, but also
That is, the recording and / or reproducing apparatus is not in use.
To the recording and / or reproducing section of the recording medium
After the installation is completed, open the lid with the lid member.
It has been made to be. The lid member covers the opening.
By closing the cover, the intrusion of dust into the outer casing,
Inadvertent entry of fingers etc. into the outer housing
Prevent unexpected accidents such as damage to recording and / or playback unit
Is what you do. [0004] The lid member is attached to the front panel.
To be rotatable or slidable.
The opening is opened and closed by moving operation.
You. By the way, on the front part of the front panel,
Are various functions for operating the recording and / or playback unit.
Operation buttons are provided. [0006] By the way, as described above,
Recording and / or playback equipment with a
The size of the opening corresponds to the size of the recording medium.
As the size increases, the lid
The size of the material also increases. This lid member can be slid
In the case of supporting, this lid member can slide
The stroke should be at least larger than the width of this lid
There must be. Therefore, the size of this lid member is
The larger, the larger the slide stroke,
The length of the member supporting the lid member in the sliding direction of the lid member
Expands and cannot be stored in the outer housing.
U. Therefore, when the size of the lid member increases, the
Id stroke cannot be enlarged. [0007] Further, when the lid member is rotatably supported.
In this case, if this lid member becomes large, this lid member
Is rotated forward or inside the outer casing.
The amount of protrusion of this lid member to the side becomes large,
The operation of the operation button cannot be performed smoothly. The recording and / or reproducing apparatus is
With the diversification of operation modes, specific operation modes
There are many operation buttons that are used only when is selected
You. In recent years, remote controllers (remote control devices)
The recording and / or playback unit by improving the function of
Various operations are arranged on the front panel.
It can be performed without using the operation buttons. this
As described above, the operation button is provided for the recording and / or reproducing device.
There are many things that are not used under normal use conditions
And, rather, an aesthetic impairment, ie, the record and / or
Hinders freedom of front panel design for playback equipment
It is something to do. Therefore, the above recording and / or reproducing apparatus is
The lid member is for opening and closing the opening.
In addition, to cover and hide operation buttons that are not normally used
Used as a member. However, the lid member is
So that it can cover not only the opening but also the operation button
When configured, it will be larger than the lid opening.
The slide stroke cannot be expanded
Would. The present invention has been made in view of the above situation.
The opening through which the recording medium is inserted is large.
When the lid member that opens and closes this opening is made larger by molding
This lid can be used without increasing the size of the device configuration.
Support the material slidably with sufficient stroke
Provide a front panel made to be able to
The purpose is to: The present invention also relates to the above-described flow chart according to the present invention.
The front panel
At least some of the operation buttons provided are in the operation mode.
The lid member slidably supported according to the
Covered or exposed to the outside
It is an object to provide a recording and / or reproducing device. [0012] To solve the above-mentioned problems,
To achieve the object, the front panel according to the present invention comprises:
Opening through which recording medium is inserted and first rack gear
And a second rack gear having a second rack gear.
Pinion between the first rack gear and the first rack gear
Mesh with each of these rack gears with a gear interposed
Is slidably supported by the panel
A lid that opens and closes the opening by a ride operation
And a member. In the front panel according to the present invention, the second
Of the second rack gear and the panel portion.
Via a pinion gear between the first rack gear provided
And meshing with each of these rack gears
Sliding operation supported on the panel so that it can slide
Opening and closing the opening formed in the panel
The lid member that covers the first rack gear is connected to the pinion.
It is slid twice the on-gear travel distance. I
Therefore, each of the rack gears slides on the lid member.
Half the length of the stroke is enough. Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.
I will explain while. The front panel according to the present invention is shown in FIGS.
