There is. In addition, the case 31 of the operation unit 30
The operation panel 31a on the front side of the device is provided with a disengagement operation body 38 as in the case shown in FIG.

In the case 31 of the operation unit 30, there is provided a turning lever 52 which turns about the shaft 51, the lower end of which is connected to the disengagement lock member 35 by a connecting pin 53, and the upper end 52a is disengaged. It faces the inclined surface 38b formed on the inner surface of the operating body 38. In this configuration example, the rotation lever 52 constitutes the lock release mechanism R2, or the rotation lever 52 serves as a lock release member. In the operation unit 30, the regulation member 54 is Y1-
The coil spring member 55 is provided so as to move back and forth in the Y2 direction, and is biased in the Y2 direction by the coil spring member 55. A pin-shaped pressed portion 54a is integrally formed at the tip of the regulating member 54, and the pressed portion 54a projects from the back surface of the operation unit 30, as shown in FIG. A recess 54b and a restricting surface 54c are formed side by side on the restricting member 54.

In this configuration example, the operation unit 30 is fixed to the rotation base 20 by locking the wedge-shaped tip portion 35c of the detachable lock member 35 in the locking hole 24b of the rotation base 20. As shown in FIG.
When the operation unit 30 is in the closed posture, the pressed portion 54a of the regulating member 54 is pushed by the front surface 12a of the nose portion 12 and moves in the Y1 direction. At this time, the regulating member 5
The concave portion 54b of No. 4 faces the turning lever 52 from the side surface, and the lower arm 52b of the turning lever 52 can enter the concave portion 54b. At this time, if the detachment operating body 38 is pressed,
The upper end 52a of the rotating lever 52 is pushed in the X1 direction by the inclined surface 38b at the inner end thereof, the rotating lever 52 rotates clockwise in FIG. 4, and the lower arm 5 of the rotating lever 52 moves.
2b enters the recess 54b, and the disengagement lock member 35 moves to X2.
The distal end portion 35c of the disengagement lock member 35 moves out of the locking hole 24b of the rotation base 20, and the operation unit 30 separates from the rotation base 20. At this time, since the regulation member 54 pushes the front surface 12a of the nose portion 12 by the elastic force of the spring member 55, the operation unit 3 in which the latch is released.
0 operates so as to jump out in the Y1 direction, and it becomes easy to hold the operation unit 30 by hand.

Further, the operation unit 30 has the rotating base 20.
When the rotation operation body 36 similar to that shown in FIG. 1 is pushed in the state of being fixed to the position, the rotation lock mechanism R1 is unlocked, and the rotation base 20 and the operation unit 30 are integrated. The elastic force of the torsion spring 16 causes the support shaft 15 to rotate about the fulcrum in the β direction. When the rotation base 20 rotates in the β direction from the closed posture, the pressed portion 5 of the regulation member 54 is pressed.
4a is separated from the front surface 12a of the nose portion 12, and the regulating member 5
4 moves in the Y2 direction by the elastic force of the spring member 55, and the lower arm portion 52b of the turning lever 52 faces the restriction surface 54c of the restriction member 54. In this state, the disengagement operation body 38 is pushed, and the inclined surface 38b causes the turning lever 52 to move.
In the case where the lower arm portion 52b hits the regulation surface 54c, the rotation is regulated even if it is rotated clockwise. Therefore, the detachment lock member 35 does not move in the X2 direction, and the lock between the operation unit 30 and the rotation base 20 cannot be released.

Also in this configuration, when the rotation base 20 is rotated to the open position, the operation unit 30 is not separated from the rotation base 20 even if the separation operation body 38 is pushed. The rotating operation body 36 and the detaching operation body 38 may be operated by sliding instead of pressing.

[0041]

As described above, according to the present invention, while the operation unit is in the closed posture, the operation unit can be rotated to the open posture and the operation unit can be detached from the closed posture. Therefore, both the opening operation and the detaching operation of the operation unit can be easily performed.

Further, when the operation unit is rotated in the direction of the open attitude, the operation unit cannot be removed even if the removal operation body is operated. Therefore, the removal operation body is erroneously operated in the open attitude, and the operation unit moves. You can prevent problems such as falling.
