As shown in FIG. 4, the tooth thickness of the teeth 9b-1 at the lower end of the rack gear 9b is thick, and the first groove 9b-2 from the lower end is a half groove filled halfway in the width direction. Therefore, the half groove 9b-2 of the rack gear 9b meshes with the teeth 23b of the gear 23, and the gear 23 and the rack gear 9b can be accurately and easily aligned.

Next, the operation of the moving mechanism of the display unit and the operation unit will be described with reference to FIGS. First, FIG.
As shown in (1), the display unit 9 is located in the concave groove 3a of the front panel 3, and the operation unit 8 is retracted and hidden behind the display unit 9. As shown in FIG. 6A, the positional relationship between the slider 10 and the operation unit 8 in this state is such that the slider 10 has moved leftward and the operation unit 8 has retreated. First, when the power switch 3b is pressed and the function button 3d is pressed, the motor 13 is driven, and the rotating shaft of the motor 13 and the motor pulley 15 rotate counterclockwise. The rotation of the motor pulley 15 is transmitted to a pulley 17a via a belt 16 and transmitted to a large-diameter gear 18a via a pinion gear 17b coaxial with the pulley 17a.
The rack gear 10d and the slider 10 move rightward when the pinion gear 19b rotates counterclockwise through the gear 19a. At the same time, the slider 10
The gear 22 and the gear 23 meshing with the rack gear 10a rotate counterclockwise, and the rack gear 9 meshing with the gear 23

Operability can be improved.

Next, when the function button 3d of the front cabinet 3 is pressed to switch to another mode that does not require the operation unit 8, the motor 13 is driven and the motor 1 is driven.
The rotation shaft 3 and the motor pulley 15 rotate clockwise. The rotation of the motor pulley 15 is transmitted to a pulley 17a via a belt 16, transmitted to a large-diameter gear 18a via a pinion gear 17b coaxial with the pulley 17a, transmitted to a gear 19a via a pinion gear 18b, and transmitted to a pinion gear. 19b rotates clockwise, so that the rack gear 1
0d and the slider 10 move to the left. Slider 1
Since 0 moves to the left, the engaging pins 8a and 8a 'of the operating portion 8 are guided by the forward portions 11b and 11b of the cam grooves 11 and 11', and the operating portion 8 retreats from the inside of the concave groove 3a. At the same time, the gear 2 meshing with the rack gear 10a of the slider 10
2 and the gear 23 rotate clockwise, the rack gear 9b meshing with the gear 23 is lowered, and the display unit 9 is lowered.

When the slider 10 moves further to the left, the engaging pins 8a, 8a 'of the operating portion 8 are guided by the introduction portions 11a, 11a of the cam grooves 11, 11', and the operating portion 8 is moved.
Moves to the rear of the concave groove 3a and the drive stop restricting portion 1
The operation pin 21a of the changeover switch 21 abuts on the end of the switch 0c, the drive of the motor 13 is stopped, and only the display unit 9 is exposed on the front panel 3 as shown in FIG.

Therefore, the operation panel 8 can be exposed to the front panel 3 only when it is necessary, and can be stored behind the front panel 3 when it is not required. Reduce the area,
The entire electronic device can be made compact.

When the operation section 8 is required, the operation section 8 can be exposed on the front panel 3 together with the display section 9. When the operation button 8b of the operation section 8 is pressed, the display section 9 is correspondingly pressed. Can be displayed on the
Operability is good.

Even if the operating button 8b of the operating section 8 is pressed, the operating section 8 is retracted because the engaging pins 8a, 8a 'of the operating section 8 are located in the holding sections 11c, 11c of the cam grooves 11, 11'. There is no danger that the operation button 8b can be pressed stably and reliably, and operability can be improved.

In the above-described embodiment, the moving mechanism of the display unit and the operation unit is applied to an electronic device. However, the present invention is not limited to this, and it goes without saying that a device other than the electronic device may be used.
