ことについての自由度を少なくしている。As described above, in the conventional operation recorder, the circular chart paper is arranged in parallel with the dial such as a speedometer, so that the outer diameter is smaller than the recording paper. Therefore, the outer diameter was large in the vertical direction. The size of the outer diameter of the operation recorder depends on the design balance of the outer diameter of other instruments, for example, the engine tachometer, so the design around the instrument panel should be innovative. Is less flexible.

態になる。The opening / closing cover 30 is unlocked when a lock 22 provided at the center of the upper portion of the main body 20 is released, and the urging force of an opening / closing spring A wound around the shaft of the hinge portion 21 causes the opening / closing cover 30 to move as shown in FIG. Open as shown. by the way,
When the opening / closing cover 30 is opened, if the opening / closing cover 30 is not stopped until it is opened to a certain angle, the opening / closing cover 30 rotates until the urging force of the opening / closing spring A disappears and becomes unstable at that position.

ある。Therefore, an opening / closing stop mechanism is provided so that the opening / closing cover 30 stops within the range in which the urging force of the opening / closing spring A is working. That is, as shown in the exploded perspective view of FIG. 7, the opening / closing stop mechanism includes an opening / closing stopper 21a provided on the hinge portion 21 of the main body 20 and a locking member 31 of the hinge portion 31 also provided on the opening / closing cover 30.
and a. The open / close stopper 21a is a state in which a cylindrical support member 21b for supporting the shaft 23 of the hinge portion 21 of the main body 20 is cut out by about 3/4 in the axial direction, and is a locking member of the open / close cover 30. 31a
Similarly, the cylindrical engaging member 31b of the hinge portion 31 of the opening / closing cover 30 is in a state in which a half strong cutout is made in the axial direction.

Ａの付勢力が作用している。When the opening / closing cover 30 is closed, the opening / closing cover 30 is manually rotated around the hinge portion 21 of the main body against the urging force of the opening / closing spring A to be closed, and is provided on the inner surface of the opening / closing cover 30 and the main body 20. It is locked by the locking mechanism (not shown). When the opening / closing cover 30 is opened, the lock mechanism is opened by inserting a key into the lock 22 arranged on the upper front part of the main body 20 and operating.
Is opened by the biasing force of the opening / closing spring A around the hinge portion 21 of the main body 20. When the opening / closing cover 30 is rotated from the closed position to an opening angle of about 110 degrees, the tip end face of the locking member 31a of the opening / closing cover 30 hits the end face of the opening / closing stopper 21a of the hinge part 21 of the main body 20, and the opening / closing cover 30 is opened. Stops rotating. The biasing force of the opening / closing spring A acts up to this position.

ーの係止部材に無理な力がかかり損傷する虞がある。However, as described above, if the opening / closing cover is stopped by the opening / closing stopper if the opening / closing cover is rotated by a certain angle when the opening / closing cover is opened, the opening / closing cover may be stopped by something. Further, when a rotational force is applied to the open / close cover, the open / close stopper and the locking member of the open / close cover may be unduly applied and damaged.

【００１３】本発明は、開いた位置にある開閉カバーに

せることができないためである。Even in this case, as in the conventional case, when the opening / closing cover 30 is closed, the opening / closing cover 30 is manually rotated around the main body hinge portion 21 against the urging force of the opening / closing spring A to close the opening / closing cover 30. It is locked by a lock mechanism (not shown) provided on the inner surface of the body 30 and the main body 20. This state is shown in FIG. When opening the opening / closing cover 30, the lock 2 placed on the upper front part of the main body 20
When the key is inserted into 2 and operated, the lock mechanism is opened and the opening / closing cover 30 is opened by the urging force of the opening / closing spring A around the hinge portion 21 of the main body 20. When the opening / closing cover 30 is rotated from the closed position to an opening angle of about 110 degrees, the end face of the tip end portion of the locking member 31a of the opening / closing cover 30 engages with the engaging portion 21a 3 of the opening / closing stopper 21a of the hinge portion 21 of the main body 20.
Then, the rotation of the opening / closing cover 30 is stopped. The biasing force of the opening / closing spring A acts up to this position. FIG. 3 shows a state in which the opening / closing cover 30 is opened. The opening / closing cover 30 stops at this position because the opening / closing stopper 21a cannot be rotated because the biasing force of the opening / closing spring B is set higher than the biasing force of the opening / closing spring A.

２１ｂの半円筒状部２１ｂ1 等で構成されている。In this state, when an external force for further rotating the opening / closing cover 30 is applied to the opening / closing cover 30, the stopper 21a contacting the opening / closing cover 30 is pushed by the locking member 31a of the opening / closing cover 30 to open / close. While resisting the urging force of the spring B, it can rotate about 100 degrees further from that position and absorb the external force. Projection 21 of open / close stopper 21a
The position where a 2 abuts on the end face of the semi-cylindrical portion 21b 1 of the support member 21b is the maximum rotation position. Open / close cover 30
When the external force applied to is removed, the opening / closing cover 30 returns to the original opened and stopped position by the biasing force of the opening / closing spring B. FIG. 4 shows these states by an end view taken along the line CC ′ of FIG. (A) is a state in which the opening / closing cover 30 is closed, and (b) is a state in which the opening / closing cover 30 is
Shows a state in which it is opened to a certain position, and (c) shows a state in which the open / close cover 30 is further rotated by applying an external force. In addition,
In this example, the damage prevention mechanism for the open / close cover according to the present invention includes an open / close stopper 21a, an open / close spring B, and a semi-cylindrical portion 21b 1 of the support member 21b.
