As a method of detecting the displacement of the key surface in a non-contact manner, for example, light is irradiated onto the upper surface of the key from above the key, and detection is performed in accordance with the amount of reflected light received. That is, since the upper surface of the key is lowered when the key is pressed and rises when the key is released, it is possible to determine that the key is pressed when the amount of received light is small and determine that the key is released when the amount of received light is large.

When infrared light is used as such light, it does not react to disturbance light (visible light), so that erroneous detection due to disturbance light can be prevented. Note that such a sensor can be constituted by an infrared LED and a phototransistor. Further, when such an optical sensor is used, the sensing level can be easily changed, and for example, by making the sensing level sweet, it is possible to make the sensor insensitive to search and play.

Further, it is more effective to provide the following correction means in each key press guide device. For example, as a correcting means, an adjuster or the like which is mounted on the keyboard instrument and abuts on the keyboard instrument is provided on the lower surface of the unit of the key press guide device, and the distance from the key surface can be adjusted (corrected) by the adjuster. Thus, the present invention can be applied to an arbitrary keyboard instrument while maintaining the detection accuracy of the optical sensor (key press detection means) for the keyboard. Such a correction means may be a volume or the like for adjusting the sensing level of the optical sensor.

As a correcting means, a member is provided at the end of the unit of the key press guide device (the end in the direction in which keys on the keyboard are arranged) so that the left and right lengths of the key press guide device can be extended and contracted. This member is placed on the time signature of the keyboard instrument (members at the left and right ends of the keyboard). As a result, the left and right lengths can be adjusted (corrected) and applied to keyboard instruments having different numbers of keys, such as 88 keys, 71 keys,.

In each key-pressing device, the key-press guide display means may illuminate the surface of the key with light.

FIG. 6 is a circuit diagram of the photosensor 6 and the detection circuit of the sensor units 4A and 4B. Although FIG. 1 shows one photosensor 6, the other photosensors 6 also have the same circuit. Infrared light emitting LED6
Numeral 1 is driven by a drive circuit (not shown) to emit infrared rays at a predetermined voltage.

A reference voltage V is applied to the collector of the phototransistor 62, and the emitter is grounded via a resistor R1 and connected to the base of a switching transistor Tr via a variable resistor R2. The divided voltage of the reference voltage V is applied to the collector of the switching transistor Tr by the resistor R3, and the emitter is grounded. Then, the collector voltage of the switching transistor Tr is output (detected signal).

With the above configuration, the infrared light emitting LED 61
Infrared light reflected from the upper surface of the key reflects the phototransistor 6
2 is received. At this time, if the key is not depressed, a constant light receiving amount is obtained by the phototransistor 62,
The emitter voltage corresponds to the amount of received light. Here, a voltage corresponding to the set value of the variable resistor R2 is applied to the base of the switching transistor Tr, and when the switching transistor Tr is turned on, the output voltage of the collector thereof becomes low level. On the other hand, when the key is pressed,
Since the optical path from the infrared light emitting LED 61 to the phototransistor 62 through the key upper surface becomes longer, the amount of light received by the phototransistor 61 decreases. Thus, when the emitter voltage of the phototransistor 62 decreases and the switching transistor Tr is turned off, the output voltage of the collector goes high.

As described above, when the output voltage of the collector of the switching transistor Tr is at a high level, it can be determined that the key is pressed, and when it is at a low level, it is determined that the key is released. Here, the threshold value for turning on / off the switching transistor Tr is variably set according to the set value of the variable resistor R2. Will be set. Therefore, by adjusting the set value of the variable resistor R2, it is possible to set the depth of the key depression that is regarded (detected) as a key depression.

If the sensing level of the photosensor 6 is set low by adjusting the variable resistor R2, it is possible to make the photosensor 6 unresponsive to the search and play. Further, adjusting the sensing level of the photosensor 6 by using the variable resistor R2 also corrects a variation in sensitivity of the photosensor 6 itself.

In the above embodiment, the number of illuminators 113 and the number of operation pads 411 are the same. However, when the number of illuminators and operation pads are different, the following is performed. When the number of the illuminators is larger than the number of the operation pads, for example, a part of the illuminators may be not used. If the number of operation pads is larger than the number of illuminators, for example, time sharing (time division) processing is performed by a program or hardware, and one illuminator is moved at two positions (2 A plurality of predetermined operation pads such as three operation pads), three positions,... Are illuminated as fixed positions. Further, for example, like a car headlamp, a plurality of filaments, a plurality of LEDs, or the like can share one lens body and emit light separately to illuminate in different directions. If such an illuminator is used, it is possible to cope with a large number of operation pads. Since the direction of the laser beam can be easily changed at a high speed, the laser beam may be used as the illuminating means. In this way, if the control is changed according to the number of illuminators and operation pads, the number of illuminators and operation pads can be input and set in the program, and the control can be selected according to the setting. You can take such a method.

As described above, since the processing according to the number of operation pads and the direction of illumination of the illuminator can be controlled by a universal pipe or a universal joint, the operation guide device of the present invention is set to a device having an arbitrary number of operation pads. be able to.

The operation guide device of the present invention can be applied not only to keyboards and operation pads (drums), but also to display of string holding positions of a koto, harp, violin and the like.
