BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation recorder for recording traveling information such as a traveling speed and a traveling distance of an automobile on recording paper, and particularly to a cartridge holding the recording paper along two directions intersecting each other. The present invention relates to a box-type operation recorder that is moved and positioned at a recording location.

[0002]

2. Description of the Related Art In order to record traveling information such as traveling speed and traveling distance of a vehicle, for example, Japanese Unexamined Patent Publication No. 10-2390.
A box-type operation recorder described in Japanese Patent No. 90 has been proposed. In this type of operation recorder, a cartridge holding a recording sheet can be freely attached to and detached from a main body having a recording needle and the like.

In the operation recorder described in Japanese Unexamined Patent Publication No. 10-239090 described above, conventionally, while the recording paper is rotated, recording of traveling information is performed by a recording needle that is in contact with the recording paper in a substantially vertical direction. It is carried out. The box-type operation recorder described above is adapted to put the recording paper in the main body along the horizontal direction from the front surface because the accommodation destination is in the console box which is opened only to the front and rear.

Therefore, for example, when the recording needle is fixed in the main body, it is necessary to vertically move the recording paper put in the main body to contact the tip of the recording needle. In a cartridge-type operation recorder that is advantageous for moving recording paper, it is necessary to move the holder in which the cartridge is loaded in two directions, horizontal and vertical.

A box-type operation recorder which realizes the movement of the holder in two directions is a box-shaped main body, a cartridge as a holder for holding the recording paper, the holder described above,
It has an intermediate frame and a guide frame.

The holder is movably provided between an attachment / detachment location where a cartridge or the like as a holder is attached / detached and a recording location where traveling information is recorded on the recording paper by the recording needle.

In the main body, the holder is moved toward the rear side of the main body from the loading / unloading location along the loading / unloading direction of the holder, and is positioned at the relay location once housed in the main body. It is moved from the relay point toward the recording point along an ascending / descending direction that intersects the loading / unloading direction such as an upward direction.

The intermediate frame is provided with a holder supporting portion for movably supporting the holder along an inclined direction in which the loading / unloading direction and the ascending / descending direction are combined. The guide frame is attached to the main body, and the recording needle described above is provided vertically.

The guide frame movably supports the intermediate frame along the loading / unloading direction. That is, both the holder and the intermediate frame are movably supported by the guide frame along the loading / unloading direction.

Further, when the holder is located at the above-mentioned relay location, the holder is restricted from moving along the loading / unloading direction so as not to move toward the inner side of the main body from this relay location. On the other hand, the intermediate frame is provided so as to be movable toward the inner side of the main body along the loading / unloading direction even after the holder is located at the relay position described above. Further, the intermediate frame is provided with a rack that meshes with a gear or the like to which a driving force of a motor attached to a guide frame or the like is transmitted.

In the holder supporting portion, the intermediate frame further moves toward the back side of the main body after the holder is located at the intermediate position and its movement along the loading / unloading direction toward the back side of the main body is restricted. By doing so, the holder is guided to rise toward the recording position.

With the above-mentioned configuration, the box-type operation recorder has the following features when the holder is moved from the loading / unloading location to the recording location.
The holder and the intermediate frame both move toward the intermediate position due to the driving force transmitted from the motor, etc., and after the holder is positioned at the intermediate position, the intermediate frame moves toward the back side of the main body. Will rise and will be located at the above-mentioned recording location.

[0013]

As described above, in the box type operation recorder, when the recording needle for recording the traveling information on the recording paper is fixed to the guide frame attached to the main body, the recording paper is held. In order to prevent the recording sheet and the recording needle from coming into contact with each other and damaging the recording needle when the holding body is taken in and out, the holding body is oriented in the loading / unloading direction and the up / down direction with respect to each other. Is moved along two different directions to position the recording paper at the recording position. For this reason, it has been necessary to provide the above-mentioned intermediate frame which is a separate body from the holding frame that detachably supports the holding body and the guide frame.

As described above, the box-type operation recorder has a holder, an intermediate frame, and the like, which are movable with respect to the main body, inside the main body. Further, in order to enable the smooth movement of the holder and the intermediate frame and the smooth guide of the holder support section described above, the holder support section and the section where the holder, the intermediate frame and the guide frame are connected to each other. The backlash is provided on the back. For this reason, the holder, the intermediate frame, and the guide frame can be slightly moved relative to each other along the width direction of the holding body, the loading / unloading direction, and the ascending / descending direction.

For this reason, when vibration from the vehicle is applied while the vehicle is running, the holder and the intermediate frame in the main body vibrate slightly with respect to the guide frame, that is, the main body, for example, along the ascending / descending direction, and the holder is mounted. The recording paper may be vibrated along a direction in which the recording paper comes into contact with and separates from the recording needle via a holder or the like. In this case, a force that changes at a frequency according to the above-mentioned vibration is applied from the recording paper to the recording needle,
There is a tendency that the recording accuracy when recording travel information on recording paper by the recording needle deteriorates.

Further, since the conventional box-type operation recorder described above accommodates the movable holder and the intermediate frame in the main body, when vibrations from the vehicle are applied during traveling, etc. , The holder and the intermediate frame may vibrate slightly and collide with each other. Then, it is conceivable that an abnormal noise is generated to give a driver an unpleasant feeling.

Therefore, an object of the present invention is to improve the recording accuracy and to improve the recording accuracy in a box type operation recorder in which the cartridge for holding the recording paper is moved in two directions intersecting with each other and positioned at the recording position. An object is to provide an operation recorder capable of suppressing abnormal noise.
