The operation recorder, which has been obliged to be installed in large trucks, buses, taxis, etc. to record data, has been formed into a generally cylindrical shape by integrating it with instruments such as speedometers and odometers. A circular recording paper is arranged in parallel on the back side of a dial such as a speedometer.
Further, the conventional operation recorder is attached to an instrument panel in front of the driver's seat so that the driver can see the dial substantially from the front together with other instruments such as a tachometer.

However, such a conventional operation recorder is
Since it is structurally impossible to form with an outer diameter smaller than the recording paper, it is necessary to consider the speedometer integrated with the operation recorder and the size balance with the speedometer on the instrument panel. The size of each of the other instruments is limited, and thus the degree of freedom to design the instrument panel around is reduced. Therefore, the applicant of the present invention has previously proposed an operation recorder which can be configured separately from an instrument such as a speedometer and can reduce the size of the exposed portion on the instrument panel.

In the above-mentioned operation recorder, when the tray portion is pulled out from the main body, the recording paper is placed on the tray portion, and the tray portion is housed in the main body, by the recording needle arranged above the tray portion in the main body. Information is written on the information recording surface of the recording paper. The operation recorder prevents information from being drawn on the recording paper and prevents information from being damaged by interference between the recording needle and the recording paper or the recording needle and the tray section. The recording needle, which is sometimes in contact with the recording paper, is moved away from the recording paper when the tray part is taken in and out.

[0005]

Therefore, when pulling out the tray portion from the inside of the main body, it is necessary to separate the recording needle from the recording paper before the tray starts to move.
When the tray portion is stored in the main body, it is necessary to bring the recording needle into contact with the recording paper after the tray portion is completely stored in the main body.

The present invention has been made in view of the above circumstances, and an object of the present invention is to set a recording needle inside the main body to the recording paper when the tray portion on which the recording paper is placed is taken in and out of the main body. It is an object of the present invention to provide an operation recorder that can move the recording needle in and out of contact with the recording paper without interfering with the recording paper when the tray is moved in and out.

I was supposed to.

Further, according to the present invention, which one of the first and second positions the operating element, in which the opening / closing state detecting means moves to the first and second positions in response to the opening / closing operation of the lock, is selected. It is assumed that the switch has a switch that comes into contact with the operating element at one of the positions and the open / close state of the internal contact is switched by the contact of the operating element. Furthermore, in the present invention, the operator is provided on one of the main body and the tray section, the switch is the other of the main body and the tray section, and the tray section is located at the information recording location. It is provided at a position that comes into contact with the operating element at any one of the first and second positions when the operating element and the switch also function as the holding means detecting means. .

[0010]

According to the present invention, the recording needle moves from the separated portion to the contact portion while the tray portion moved from the recording paper exchange portion is held by the holding means at the information recording portion. The recording needle does not interfere with the recording paper when moving to. Similarly, in the state where the tray is held at the information recording position by the holding means and the lock is moved from the closed position to the unlocked position, the recording needle moves from the contact position to the separated position, and the recording is performed. Since the holding unit of the tray section can release the needle while the needle is separated from the recording paper, the movement from the information recording location of the tray section to the recording paper replacement location can be performed after the recording needle leaves the recording paper. Therefore, the recording needle does not interfere with the recording paper when the tray is moved to the recording paper exchange position.
