DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a mechanism for pressing a recording sheet on a rotary table of an operation recorder for recording information such as a traveling speed and a traveling distance of an automobile on the recording sheet.

[0002]

2. Description of the Related Art In an operation recorder for recording information such as a traveling speed and a traveling distance of a vehicle on a recording paper while rotating a rotary table on which a circular recording paper is placed with the passage of time, the rotation of the rotary table is known. In order to reliably transmit the torque to the recording paper to prevent the recording paper from running idle, and to prevent the recording paper from spinning due to backlash between the rotary table and the recording paper, the recording position of information on the recording paper may be reduced. In order to prevent the position from deviating from the current time, the recording paper is pressed against the rotary table, so that the engagement claws of the rotary table are cut into the recording paper.

[0003] As a conventional mechanism for pressing the recording paper against the rotary table and causing the engagement claws to bite into the recording paper, for example, there is a mechanism disclosed in Japanese Patent Publication No. 53-23706. In this mechanism, a recording paper is placed on a rotary table, its center hole is fitted into a rotary shaft of the rotary table, and further, when the cover is closed so as to cover the recording paper, it is rotatably supported at the center of the cover. An annular fastening member engages with the front end side of the rotating shaft, and the engaging force pulls the fastening member toward the rotary table, so that the end face of the fastening member allows the recording paper portion around the center hole to be attached to the rotary table. The recording paper portion is pressed down so that the engaging claw of the rotary table bites into the recording paper portion.

The advantage of this conventional mechanism is that the position of the engaging claw is aligned with the end face of the fastening member when the cover is closed so that the pressing force of the fastening member is directly applied to the engaging claw portion of the rotary table. With this configuration, the engaging claw can be reliably engaged with the recording paper by pressing the fastening member. In addition, to increase the diameter of the tightening member within a range that does not affect the information recording on the recording paper, and to separate the position of the engaging claw from the rotation shaft to transmit the rotational force from the rotary table to the recording paper. Therefore, even if the amount of engagement of the engaging claw with the recording paper is small, the rotational force is transmitted from the rotary table to the recording paper, so that the pressing force of the fastening member on the recording paper is small. In that it can be done. Therefore, in the conventional mechanism, the recording paper is pressed by a relatively small force, such as a pulling force of the fastening member toward the rotary table, which is generated by the engagement of the fastening member with the rotating shaft, and the recording is performed on the engagement claw. Even when the paper is engaged, the rotation force of the rotary table can be sufficiently transmitted to the recording paper.

However, in an operation recorder in which recording for a plurality of days is continuously performed without exchanging recording paper, the above-described method of pressing the recording paper against a rotary table cannot be adopted. The reason is that the configuration of the recording paper for continuous recording is slightly different from the configuration of the normal recording paper. That is, the recording paper for continuous recording is composed of a plurality of recording papers, a backing paper on which these recording papers are superimposed, and a center hole of the backing paper which is attached to the center of the backing paper and inserted into the operation recording meter. And a connecting tape that is bridged between the outer edges of the recording paper and the mount to prevent relative rotation of each recording paper with respect to the mount. At the same time, the operation recorder for continuous recording is such that the cylindrical member is fitted on the rotating shaft, the recording paper for continuous recording is placed on the rotating table, and the recording paper for continuous recording is moved together with the rotating table with the passage of time. After recording the information by contacting the recording needle with the uppermost recording paper while rotating it, the connecting tape between the recorded recording paper and the backing paper is cut with a cutter, and the recording paper is cut at the upper end of the cylindrical member. It is configured to be attracted to the side so as to be independent of other recording papers, and to be held non-rotatably.

For this reason, if the recording paper for continuous recording is pressed directly to the rotary table by the fastening member as in the conventional recording paper pressing mechanism, the recorded recording paper is made independent from other recording papers. And it cannot be held unrotatably. Therefore, in an operation recorder capable of continuous recording, a method is employed in which a pressing member is engaged with the end of the cylindrical member, and the mount of the recording paper for continuous recording is pressed against the rotary table via the cylindrical member. ing.

In the case of the method in which the cylindrical member is pressed by the pressing member, the position of the engaging claw of the rotary table is radially outward of the rotary table from the cylindrical member, and the rotary table portion to which the pressing force of the pressing member is applied. Is shifted in the radial direction, so that the engagement claw does not bite into the backing paper compared to the conventional recording paper holding mechanism in which the holding force of the fastening member is directly applied to the rotary table portion provided with the engagement claw. , The amount of engagement is reduced. Therefore, it is conceivable to provide an engagement claw on the rotary table portion as close as possible to the cylindrical member so that the engagement amount of the engagement claw with the mount is as close to the conventional one as possible.

However, the position of the engaging claw is a cylindrical member, that is,
When approaching the rotating shaft side, the rotating torque of the rotating table for rotating the recording paper must be increased,
When the rotary table is rotated by the same torque as in the related art, it becomes impossible to transmit the rotational force to the recording paper. When the position of the engagement claw is brought closer to the rotation shaft, the engagement claw is lengthened so that the engagement between the engagement claw and the mount can withstand rotation of the rotary table with a larger torque than before. You have to increase the amount of digging into
The engaging claw is engaged not only on the backing sheet and the last day recording paper but also on the day preceding one day recording paper, which hinders the independent operation from the last day recording paper after recording. There is a risk.

On the contrary, the position of the engaging claw is changed to a cylindrical member, that is,
It is also conceivable to move the engaging claw away from the rotation shaft and instead urge the engagement claw toward the mount with a spring plate or the like so that the engagement amount of the engagement claw to the mount is as close to the conventional one as possible. In this case, since the elastic member is opposed to the elastic force of the spring plate, it is necessary that the pressing member presses the cylindrical member with a force larger than the conventional pressing force.

When these factors are taken into consideration, in order to reliably transmit the rotational force of the rotary table to the recording paper when recording information on the recording paper for continuous recording, the holding member needs to have a larger torque than the conventional one. It is necessary to adopt either a configuration for holding down the member or a configuration for rotating the turntable with a larger torque than in the past. Among them, in order to increase the rotational torque of the rotary table, it is necessary to change the internal power source such as a clock mechanism to a large torque source, which greatly affects the product cost, which is not preferable. Therefore, conventionally, in a state where the cylindrical member is fitted on the rotary shaft and the recording paper for continuous recording is placed on the rotary table, a cap is screwed into the tip of the rotary shaft, and the cylindrical member is pressed toward the rotary table with the lower surface of the cap. A presser holding mechanism was used.

[0011]

However, in the conventional cap-type holding mechanism, the rotary table rotates when the cap is screwed in, and a load is applied to a rotary drive source and an intermediate power transmission system of the rotary table. In order to reduce the load, it is necessary to secure a large accommodation space and make the gears of the power transmission system thick and increase the tooth surface, or it is necessary to form the gears with high rigidity at the cost of parts. There was a defect. Further, in the above-described conventional holding mechanism, since the cap is formed separately from the rotating shaft side, there is a problem that the cap may be lost while being removed from the rotating shaft. .

Further, in the conventional holding mechanism described above, when the cap is screwed in, the cylindrical member rotates with respect to the rotary table before the engaging claw is completely engaged with the mount, and the rotation according to the current time is performed. Even if the continuous recording paper is placed on the rotary table at the position, the rotational position of the continuous recording paper will be shifted after the cap is screwed, so the continuous recording paper is rotated according to the current time after the cap is screwed. In order to re-adjust the position, there is a problem that it is necessary to provide a manual rotation mechanism of the rotary table.

The present invention has been made in view of the above circumstances,
A first object of the present invention is to provide an operation recorder that can prevent an increase in the space for disposing a power transmission system of a rotating shaft and the cost of parts, and also prevent a rotational position shift of a recording sheet due to a pressing operation.
