Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an operation display device for an auto player, which displays the operating state according to the operating mode during the operation of the auto player.

Generally, an auto player has an internal mechanical part and an external operating member such as a lever or a push button that are mechanically interlocked, and the operating members themselves are interlocked with each other.

In this auto player, the operating state can be confirmed by checking the direction in which the lever and push button are tilted and the state in which the push button is pressed.

Incidentally, in recent years, devices have been developed that utilize electric drive sources such as motors for some internal mechanisms and utilize switches for control.

Since it is not possible to determine which switch is closed in this device, a light spot indicator is provided near each switch and is lit to indicate the operating state.

However, in this case, the operating mode cannot be known unless the status of the light spot indicators near each switch is checked individually.
In addition, when performing the next operation, the above-mentioned confirmation must be performed before the next operation, and the number of parts also increases, resulting in an increase in the number of man-hours.

This idea was made in view of the above points, and its purpose was to provide a display consisting of one seven segment and a colon in one place, and to use this display to display all operating status. It is an object of the present invention to provide an operation display device for an auto player that allows easy confirmation of the operation mode, reduces the number of parts, and improves workability.

Another purpose of this invention is to automatically display the initial letter for each action in accordance with the automatic action of the auto player, so the listener can simply look at the display and
An object of the present invention is to provide an automatic player operation display device that allows the user to know the operation status of the player.

Next, one embodiment of this invention will be described with reference to the drawings.

A is the auto player body, 1 is the panel, 2 is the turntable, 3 is the tone arm, and 4 is the turntable 2
The rotation speed selection operation button 5 is a power switch that switches between actuation and automatic mode. Manual operation is possible by rotating it to the left from the intermediate position in Fig. 2, and manual operation is possible by rotating it to the right. Automatic operation takes place.

Reference numeral 6 denotes a display comprising a seven segment 61 and a colon 62, which is connected to the power switch 5, a group of switches to be described later, and switches provided in the internal mechanism to display the operating status.

T is a repeat switch that sets a repeat command to repeat the performance when pressed once, and cancels repeat when pressed again. 8 is an up/down switch that raises the arm elevation when pressed once and lowers it when pressed again. ,
9 is a start/eject switch that starts automatic performance, stops the performance midway, and returns the arm.

Next, the operation will be explained based on the above configuration. When the power switch 5 is now turned to the manual (AUTO0FF) side, the seven segment 61 of the display 6 will display "F".

In this case, the automatic operation is completely canceled, so even if the other switches 7 to 9 are operated, the arm 3 will not move and the display will not change.

Next, when the power switch 5 is turned to the automatic (AUTO0FF) side, the seven segment 61 of the display 6 displays "-" to indicate that the system is on standby.

In this state, when you place the record on the turntable 2 and press the start/eject switch 9, the seven segment 6
If 1, "S" is displayed to indicate that arm 3 is in lead-in operation.

When the arm 3 moves to the set position by this lead-in operation, the seven segment 61 displays "P".

When the performance ends and this is detected, the seven segment 61barRJ is displayed.

At the same time, the arm 3 performs a return operation and moves toward the armrest, and when the arm 3 returns to the armrest and enters the standby state again, the seven segments 61r-J are displayed.

Further, when the start/eject switch 9 is pressed during the above-mentioned performance, the arm 3 performs a return operation and moves toward the armrest, and the seven segment 61 displays rRJ.

On the other hand, when the repeat switch T is pressed, a repeat command is issued and the colon 62 of the display 6 is lit, and this state is maintained until the repeat switch 7 or the start/eject switch 9 is pressed again.

Further, when the up/down switch 8 is pressed, the seven segment 61 displays "U", and continues to be displayed until the switch 8 is pressed again.

The display device of this invention can be used not only for the above operations but also for various operations of conventional auto players.

As mentioned above, this idea is based on the fact that there is a
A seven-segment display is provided, and this display is automatically switched according to the player's actions, that is,
P at the time of play, S at the start of R1 at the time of return
Since the characters are displayed, the characters can be changed without any operation by the listener, so the listener can know the operating status of the player by looking at the characters, and the device is also simple and inexpensive. It is something.
