Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operation panel for a recording medium performance device, and more particularly to an operation panel for a recording medium performance device suitable for use in an audio device mounted on a car or the like that requires a small space.

In the case of a cassette tape deck or the like in a so-called car stereo system that is installed near the driver's seat of an automobile, the area allowed for its operating surface or display surface is extremely limited. As an example, 18
It is common to provide not only a hole for attaching and detaching the cassette half, but also a switch element for controlling the operation of the cassette tape deck body and a display element within a small area of about 5 cm.

The only places where the driver can easily operate are extremely limited spaces such as parts of the dart board or console, and therefore, in addition to the above-mentioned elements, there are also radio tuner function operation controls and other equipment in the small space mentioned above. It is also required to add various elements for display. As a solution for efficiently housing these various elements in such a small area, there is a structure proposed by the applicant of the present application (see Japanese Patent Application No. 57-32141).
That is, an operating element, a display element, etc. are provided on the front surface of the lid covering the cassette half insertion hole, and the lid is opened when the cassette half is attached or removed. By doing so, the lid body covering the cassette half insertion hole can be used also as an operation panel, and various elements can be arranged extremely efficiently in a small area.

In such a configuration, the operation switch elements and the like are arranged only on the front of the lid body, so if there are many elements, the element arrangement density will increase and cause erroneous operation, so elements that are used infrequently must be deleted. It has the disadvantage that it cannot be used.

The purpose of the present invention is to make it possible to arrange the operation switch elements, display elements, etc. without increasing the element arrangement density, even in a multi-functional recording medium performance device that requires many operation switch elements, display elements, etc. The goal is to provide an operation panel that can be used.

The operation panel of the recording medium performance device according to the present invention is configured to be openable and closable, and an operation switch element, a display element, etc. are arranged not only on the front side of the panel but also on at least one of the remaining surfaces of the panel other than the front side (for example, the back side). It is characterized by the fact that

The present invention will be explained below using the drawings.

FIGS. 1 and 2 are diagrams showing an embodiment of the present invention, in which an opening/closing panel of a lid covering a cassette half insertion hole of a cassette tape deck is also used as an operation panel. FIG. 1 shows a perspective view of the panel 1 when it is closed, and FIG. 2 shows a perspective view of the panel 1 when it is opened. A panel 1 is provided on the front surface of the tape deck main body 2 to cover a cassette half insertion hole 3 (see FIG. 2), and is configured to be openable and closable. On the front of this panel 1,
Electronic volume control switch 4 and 5
is installed. Both switches 4 and 5 have the function of increasing and decreasing the volume while they are pressed, respectively.

Also, PAUSE (pause), FF (fast forward), REW
Operation switches 6 to 10 such as (rewind), PLAY (reproduction), and STOP (stop) are provided on the front surface of this panel 1. These switches 6-10 are
In addition to functioning as the various operation command switches mentioned above when operating as a tape deck, it also functions as a switch for commanding various functions of the tuner when the tuner is in use, as shown at the bottom of each switch. That is, switches 6 and 7 are for down (frequency reduction) and up (frequency increase) during scan channel selection, and switches 8 and 9 are for down and up (frequency increase) during seek channel selection. Switch 10 is a reception frequency band setting switch. The functions of the switches 6 to 10 are selected by a switch 11 provided on the front surface of the deck body 2.

An open-eject switch 12 is further provided on the front surface of the panel 1, and a display section 1 is also provided.
3 is installed. This display section 13 uses, for example, a two-layer liquid crystal display element (LCD), with the first layer used for tape deck-related displays and the second layer used for tuner-related displays.

Next, the back side of the panel 1 will be explained with reference to FIG. 2. Reference numeral 14 is a loudness button, and 15 is a display element thereof, which is made of, for example, an LED (light emitting diode). 16 is a Dolby switch for tape noise reduction, and 17 is its display element. 18 and 19 are metal/normal switching switches for the tape and their display elements, 20 and 21 are auto blank skips for the tape.
(Skip) function on/off switch and its display element, 22 and 23 are the tuner's monaural/
A stereo selector switch and its display element.
Incidentally, on the left side of the front surface of the main body 2, knobs 24 and 25 for adjusting treble and bass are provided.

In this way, by attaching elements that are used relatively less frequently than the switch elements and display elements provided on the front side to the back side of the panel 1, not only the front side of the panel 1 but also the back side can be used effectively. It will be possible.

FIG. 3 shows another embodiment of the present invention, and shows the first and second embodiments.
Parts equivalent to those in the figures are designated by the same reference numerals. In this example, in addition to the front and back surfaces of the operation panel 1, necessary switch elements or display elements 24 to
26 is installed, making it possible to more efficiently handle the multi-functionalization of equipment. It goes without saying that a structure may also be used in which various elements are attached to both sides of the panel 1.

FIG. 4 is a schematic block diagram of the apparatus shown in FIGS. 1 and 2, in which equivalent parts are designated by the same reference numerals. Reference numeral 41 denotes a controller, and commands from various operation switch elements attached to the operation panel 1 are applied to this controller 41 and become necessary system command signals to the tape deck 42, tuner 43, and main amplifier 44.
performs various controls. 45 indicates a speaker. Displays corresponding to various operation switches are displayed on the panel 1, but such display sections and display elements are omitted in FIG. 4 for the sake of simplification.

Electrical connections between the operation switch elements and display section in the operation panel 1 and the controller 41 (preferably provided in the deck body 2) are made using flexible jumper wires. In order to reduce the number of signals, all signals from the operating switches may be digitized and transmitted in a serial transmission format. Furthermore, it is also possible to set it as wireless. That is, signals can be sent and received optically, and the panel can be separated from the main body to provide a remote control system.

As mentioned above, the recording medium playing device of the present invention includes a lid that exposes the recording medium insertion port of the playing device main body in an open state and hides it in a closed state. Each is provided with a keyboard switch and a display, and the front keyboard and display are also used to issue commands to devices other than the performance device and to display the operating status of the other devices. The part corresponding to the recording medium insertion slot is also used for arranging the keyboard switch and display, making the lid extremely effective. Therefore, it is possible to implement a large number of operation switches without downsizing, and for example, among the switches installed on the front of the lid, those that are used less frequently can be moved to the back of the lid and displayed on the front. It becomes possible to make the container large and easy to see. In addition, various modes set by the keyboard switch arranged on the back side of the lid can be easily checked by the display on the back side, so it is suitable for in-vehicle equipment. Furthermore, when the main body of the musical performance device is not in use, you can operate other devices and change the contents of the display to displays related to other devices by operating the keyboard switch on the front of the lid, without having to take the trouble to open or close the lid. Since it is also possible to switch, the operability is also extremely good.
