the display panel 5, and four display windows 5a, 5b, 5c and 5d are opened at intervals of, for
example, 90 degrees around the circular hole 6 ing. In the vicinity of the display windows 5a, 5b,
5c and 5d, genre names of classic (CLASSIC), jazz (JAZZ), pops (POP) and rock (ROCK) are
described respectively. A mark 10 which is a display unit to be described later is exposed in any
one of the display windows 5a, 5b, 5c, 5d.
[0015]
A circular operation portion 8 a of the rotation operation portion 8 is rotatably fitted in the large
diameter circular hole 6 of the display panel 5. The rotation operation unit 8 is integrally formed
of a circular operation unit 8a and a disk portion 8b having a larger diameter than the circular
operation unit 8a. Fine irregularities are formed on the circumferential portion of the circular
operation portion 8a of the rotation operation portion 8 in order to make it easy for the finger to
be caught and rotated. That is, a step is formed at the boundary between the circular operation
portion 8 a of the rotation operation portion 8 and the disk portion 8 b. A plurality of, in this case
six, marks 10 are arranged at predetermined places on the periphery of the surface of the disk
portion 8b. The six marks 10 are arranged at an angle of about 68 ° with one mark 10 and
about 52 ° with the other mark 10 with respect to the marks 10 adjacent to each other. Thus,
when the rotary operation unit 8 is rotated, the mark 10 can be exposed on any one of the
display windows 5a, 5b, 5c, and 5d.
[0016]
A gear 11 is fixed to the center of the back surface of the rotation operation unit 8, and a pinion
gear 15 fixed to a shaft 13e of a rotary switch 13 having four contacts 13a, 13b, 13c and 13d is
engaged with the gear 11 doing. When the rotation operation unit 8 and the gear 11 rotate 30
°, the pinion gear 15 and the shaft 13e of the rotary switch 13 rotate 90 °, and the gear ratio
is set so that the contact is switched.

and the shaft 13e of the rotary switch 13 also rotates clockwise, so that the contacts of the
contacts 13a, 13b, 13c, 13d are continuously connected in a clockwise direction. It is supposed
to
[0018]
On the other hand, when the operation portion 8a of the rotation operation portion 8 is operated
to rotate clockwise, the disk portion 8b and the gear 11 fixed thereto also rotate clockwise. Then,
the pinion gear 15 meshing with the gear 11 rotates counterclockwise, and the shaft 13e of the
rotary switch 13 also rotates counterclockwise, and continues counterclockwise to the contacts
13a, 13d, 13c, 13b. Are connected in sequence. Thus, since the rotary switch 13 is used, the
rotation operation unit 8 can be freely rotated in a desired direction.
[0019]

frequency characteristic for ROCK. Further, when the rotary operation unit 8 is operated to rotate
clockwise by about 30 °, as shown in FIG. 4 (e), the disk portion 8b and the gear 11 are also
rotated by about 30 °, and the display window 5c of the POP is displayed. While the mark 10 is
exposed, the rotary switch 13 is rotated about 90 °, connected to the next contact 13c, and
adjusted to the frequency characteristic for POP.
[0021]
FIG. 5 is a view showing how marks are displayed in the display windows 5a, 5b, 5c and 5d of
the respective genres when the rotary operation unit 8 is operated to rotate counterclockwise.
FIG. 5A shows a state in which the mark 10 is exposed in the display window 5d of ROCK, and
the rotary switch 13 is connected to the contact 13d and adjusted to the frequency characteristic
for ROCK. Then, when the rotary operation unit 8 is operated to rotate about 30 degrees in the
counterclockwise direction, as shown in FIG. 5B, the disk part 8b and the gear 11 also rotate
about 30 degrees, and the display window 5a of CLASSIC The mark 10 is exposed, and the rotary
switch 13 is rotated about 90 °, connected to the next contact 13a, and adjusted to the
frequency characteristic for CLASSIC.
[0022]
Furthermore, when the rotary operation unit 8 is operated to rotate about 30 degrees in the
counterclockwise direction, as shown in FIG. 5C, the disk part 8b and the gear 11 also rotate
about 30 degrees, and the JAZZ display window 5b The mark 10 is exposed, and the rotary
switch 13 is rotated about 90 °, connected to the next contact 13b, and adjusted to the
frequency characteristic for JAZZ. Then, when the rotary operation unit 8 is operated to rotate
about 30 degrees in the counterclockwise direction, as shown in FIG. 5D, the disc part 8b and the
gear 11 are also rotated about 30 degrees, and the POP display window 5c The mark 10 is
exposed, and the rotary switch 13 is rotated about 90 °, connected to the next contact 13c, and
adjusted to the frequency characteristic for POP. Furthermore, when the rotary operation unit 8
is operated to rotate about 30 degrees in the counterclockwise direction, as shown in FIG. The
mark 10 is exposed, and the rotary switch 13 is rotated about 90 °, connected to the next
contact 13d, and adjusted to the frequency characteristic for ROCK.
[0023]
Therefore, since the rotary operation unit 8 can be rotated continuously in any direction, the
desired function can be selected quickly and smoothly, and the operability can be improved, and
08-05-2019

it is continuously rotated. Therefore, the rotation operation unit 8 and the switch 13 are not
subjected to an unreasonable force, and breakage or failure can be reliably prevented.
[0024]
In addition, when the rotary operation unit 8 is rotated, the function is switched by the switch 13
and the mark is displayed on the display window of the selected function, which is extremely
simple.
[0025]
In the above-described embodiment, the function of the function selection display device is the
adjustment of the frequency characteristic. However, the function is not limited to this, and it is
needless to say that other functions may be used.
[0026]
Although four functions are described, the present invention is not limited to this, and of course,
other plural functions such as two, three, and five may be used.
[0027]
As described above, according to the present invention, since the rotation operation unit can be
continuously rotated in any direction, a desired function can be selected quickly and smoothly,
and the operability is improved. In addition, since rotation is continuously performed, no
excessive force is applied to the rotation operation unit and the function switching means, and
breakage or failure can be reliably prevented.
[0028]
In addition, since the function switching means switches the function and the display unit is
displayed on the display window of the selected function when the rotary operation unit is
operated to rotate, it is extremely simple.
